Description

  The present invention relates to a battery lid device that holds a battery in a storage portion and is fixed to the insertion port in a state in which the entire insertion port is covered by sliding in a predetermined direction from the temporarily closed state, and a battery storage including the same Relates to the device.

  Conventionally, as a battery box which is a battery storage device of an electronic device such as a digital still camera, for example, an AA battery is inserted vertically into a storage portion, and a battery lid device (hereinafter simply referred to as a lid). There is a type that closes). In this type of battery box, electrode contact pieces, which are conductive portions, are provided on the bottom surface of the storage portion and the inner side surface of the lid, respectively. For example, the bottom side of the storage unit is a positive electrode and the lid side is a negative electrode. When the battery is stored in the storage unit and the lid is closed, each contact piece comes into contact with each terminal of the battery. .

  By the way, in such a type of battery box, if the direction of the battery is wrongly inserted, that is, reversely inserted, a current flows in an unintended direction in the design, causing a problem such as a short circuit. In view of this, various attempts have been made so far to prevent this reverse insertion and to prevent the circuit from being affected even if it is reversely inserted.

  For example, a reverse insertion prevention structure in a battery box having a negative electrode on the lid side is known (see, for example, Patent Document 1). Specifically, as shown in FIGS. 9 to 11, an escape hole 14 having a diameter slightly larger than the diameter of the positive electrode terminal 13 of the battery 12 is formed in the central portion of the lid-side battery contact piece 11. Since the diameter of the negative electrode terminal 15 of the battery 12 is larger than the escape hole 14, when the battery 12 is correctly inserted as shown in FIG. 10 (a), the lid-side battery contact piece 11 is connected to the negative electrode terminal 15 of the battery 12. In full contact with On the other hand, when the battery 12 is reversely inserted as shown in FIG. 10B, the positive terminal 13 of the battery 12 is placed in the escape hole 14. Thereby, it is possible to prevent the positive electrode terminal 13 of the battery 12 from erroneously contacting the lid-side battery contact piece 11.

  Incidentally, the allowable range of the dimensions of each part of the battery 12 is determined by IEC (International Electrotechnical Commission) standards. For example, as shown in FIG. 9, the allowable range of the diameter D1 of the AA size battery 12 is 13.5 mm to 14.5 mm, the minimum diameter of the negative electrode terminal 15 is 7 mm (the maximum diameter is not set), and the diameter of the positive electrode terminal 13 The allowable range of D2 is defined as 4.2 mm to 5.5 mm. The storage portion 17 that receives this is naturally set to be larger than the diameter D1 of the battery 12 (for example, 14.6 mm of the maximum battery diameter +0.1 mm). Then, the battery 12 manufactured with the minimum allowable dimension or a size close to the minimum allowable dimension moves greatly in the storage portion 17 as shown in FIGS. 11 (a) and 11 (b). In the configuration, there is a possibility that the positive electrode terminal 13 of the battery 12 inserted in reverse is in contact with the lid-side battery contact piece 11.

  For this reason, it is necessary to design the lid-side battery contact piece 11 assuming the positive electrode terminal 13 having the smallest diameter D1 and the largest diameter in preparation for the case where the battery 12 is reversed. Specifically, the diameter D3 of the escape hole 14 of the lid side battery contact piece 11 is 6.6 mm (the maximum diameter of the positive electrode terminal 13 is 5.5 mm + the clearance between the battery 12 having the minimum allowable dimension 12 and the housing portion 17 is 1.1 mm). If it is designed to be large and the minimum diameter of the negative electrode terminal 15 is less than 7 mm, the distance between the positive electrode terminal 13 and the escape hole 14 when the battery 12 having the minimum allowable dimension moves to the maximum can be 0.2 mm, with a certain margin. You can have it.

However, the positive terminal 13 of the battery 12 and the lid-side battery contact 11 may come into contact with each other due to factors such as design tolerances, assembly errors, and the minimum allowable size of the battery tilted with respect to the lid-side battery contact 11. There can be. On the other hand, if the diameter D3 of the escape hole 14 of the lid side battery contact piece 11 is widened to avoid contact between the positive electrode terminal 13 of the battery 12 and the lid side battery contact piece 11, the negative electrode when the battery 12 is correctly inserted The contact area with the terminal 15 is reduced, and the reliability of conduction is impaired.
Japanese Patent No. 3258933 (page 2-3, FIG. 5-6)

  As described above, the contact between the positive electrode terminal and the conductive portion when the battery is inserted backward is ensured while ensuring the reliability of conduction between the negative electrode terminal and the conductive portion when the battery is correctly inserted into the storage portion. A configuration that can be surely prevented is desired.

  This invention is made in view of such a point, and it aims at providing the battery cover apparatus which can prevent the illegal conduction | electrical_connection of the battery wrongly inserted in the accommodating part, and a battery accommodating apparatus provided with the same. .

  The battery lid device according to claim 1 has a first terminal having either positive or negative polarity and a second terminal having a smaller outer diameter than the first terminal and having a polarity opposite to the first terminal. With respect to a storage portion having an insertion port into which a battery can be inserted, the insertion port is covered with the entire insertion port by sliding in a predetermined direction from a temporarily closed state that covers at least a part of the insertion port. A lid device for a battery that is fixed to the housing and holds the battery in the storage portion, the lid body being slidable in the predetermined direction, provided on the lid body, wherein the second terminal can be inserted. And a concave portion in which the first terminal cannot be inserted, and a conductive portion that is provided outside the concave portion of the lid main body and can be brought into contact with the first terminal. The second terminal facing the insertion port of the battery erroneously inserted into the storage portion is temporarily closed The inserted second portion of the battery inserted into the inserted portion in a temporarily closed state is formed by sliding the lid body relative to the inserted portion. And a holding part that guides and holds it.

  When the battery is mistakenly inserted into the storage portion, the lid main body is temporarily closed, so that the second terminal facing the insertion port is inserted into the inserted portion, and the lid main body is slid from the temporary closed state. When the closed state is established, the second terminal of the battery is guided and held by the holding portion. For this reason, even if a battery having a battery body having a minimum allowable dimension is erroneously inserted into the storage portion, the held second terminal does not come into contact with the conduction portion, so that unauthorized conduction can be reliably prevented.

  The battery lid device according to claim 2 is the battery lid device according to claim 1, wherein the conducting portion is formed along at least a part of the periphery of the holding portion.

  Then, by forming the conducting part along at least a part of the periphery of the holding part, the area of the conducting part can be increased, and the contact between the second terminal of the battery correctly inserted in the storage part and the conducting part Area is secured.

  The battery storage device according to claim 3, wherein the storage portion includes an insertion port into which the battery can be inserted, and the battery lid according to claim 1, wherein the insertion port can be closed by a sliding operation in at least a predetermined direction. Device.

  In addition, by providing the battery lid device according to claim 1 or 2, even when the battery is erroneously inserted into the storage portion, unauthorized conduction can be reliably prevented.

  According to the present invention, it is possible to prevent unauthorized conduction of a battery erroneously inserted into the storage unit.

  Hereinafter, the configuration of a battery lid device according to an embodiment of the present invention will be described with reference to FIGS.

  In FIG. 5, reference numeral 21 denotes a camera. The camera 21 is, for example, a digital still camera, and includes a camera body 22, a lighting device 23 that is a strobe device provided integrally with the camera body 22, and a battery storage device. And a battery box 24. The camera body 22 includes a case body 25 and a lens barrel 26 attached to the front surface of the case body 25. The lens barrel 26 includes a photographing lens having a so-called zoom mechanism that can change the angle of view. In addition, although not shown in the figure, the case body 25 controls an image sensor that captures light passing through the photographing lens, an image processing circuit that processes a signal output from the image sensor, a recording medium that records image data, and each unit. A control device or the like is stored. The case body 25 is provided with operation means such as a shutter button and a zoom lever for changing the angle of view, and display means such as a liquid crystal display panel serving as a finder is provided on the back side.

  As shown in FIGS. 1 to 8, the battery box 24 is rotated with respect to the box body 31 as a storage device body integrally formed on one side of the case body 25 and the box body 31. And a battery lid device 32 (hereinafter simply referred to as a lid 32) slidably provided.

  The box body 31 is formed so as to bulge to the front side of the case body 25. A storage part 35 capable of storing, for example, two batteries 34 is formed therein, and the battery 34 is inserted into the storage part 35. An insertion slot 36 is formed in the lower part.

  As shown in FIGS. 5, 7, and 8, the battery 34 serves as a power source for an image processing circuit or the like. For example, an AA size substantially cylindrical battery body 41 and a shaft of the battery body 41 are provided. A negative electrode terminal 42 that is a cylindrical first terminal protruding at one end in the direction, and a cylindrical second terminal that protrudes at the other end in the axial direction of the battery body 41 and has a smaller outer dimension (diameter) than the negative electrode terminal 42. And a positive electrode terminal 43 which is a terminal. The battery main body 41, the negative electrode terminal 42, and the positive electrode terminal 43 are substantially coaxial.

  The storage unit 35 includes storage units 35a and 35b that each store one battery 34, for example. A wall-shaped partition part 35c that partitions the storage parts 35a and 35b is formed between the storage parts 35a and 35b. Also, one battery contact piece that contacts the positive electrode terminal 43 of the battery 34 inserted into the one storage part 35a at the bottom of one storage part 35a, that is, inserted so that the positive electrode terminal 43 side is the bottom side. 47 is provided, and the bottom of the other storage portion 35b is correctly inserted into the other storage portion 35b, that is, contacts the negative electrode terminal 42 of the battery 34 inserted so that the negative electrode terminal 42 side is the bottom side. The other battery contact piece 48 is provided.

  Here, the allowable ranges of the dimensions (diameter dimensions) of the battery main body 41, the negative electrode terminal 42, and the positive electrode terminal 43 of the battery 34 are determined by IEC standards. For example, the allowable range of the diameter of the AA size battery 34 Is 13.5 mm to 14.5 mm, the minimum diameter of the negative electrode terminal 42 is 7 mm (the maximum diameter is not set), and the allowable range of the diameter of the positive electrode terminal 43 is 4.2 mm to 5.5 mm. For this reason, the storage portions 35a and 35b are each set to be larger than the maximum diameter of the battery main body 41 of the battery 34. Therefore, when the batteries 34 stored in the storage portions 35a and 35b have a minimum allowable size or a size close to the minimum allowable size, the batteries 34 move up and down and left and right in the plan view in the storage portions 35a and 35b, respectively.

  One battery contact piece 47 is electrically connected to the plus side of an image processing circuit, for example.

  The other battery contact piece 48 is electrically connected to the minus (ground) side of an image processing circuit, for example.

  The insertion port 36 is opened and closed by the lid 32, and is formed in the lower part of the case body 25 so as to open. Further, the insertion port 36 is formed in a stepped shape with respect to the bottom surface of the case body 25.

  On the other hand, as shown in FIGS. 1 to 6, the lid 32 has a lid body 51 formed in a plate shape, and projects from the lid body 51 so that the lid body 51 can be moved relative to the case body 25. Hinges 52, 52 to be attached, and a lid-side battery contact member 53 attached to the lid body 51. The lid-side battery section member 53 includes a positive electrode guard 55 having insulating properties as one erroneous insertion conduction preventing member fitted in a central portion of the negative electrode side contact piece portion 54 as the first contact piece portion, and a second contact piece. And a negative electrode guard 57 having an insulating property as another erroneous insertion conduction preventing member attached to the positive electrode side contact piece portion 56 as a portion. The lid 32 is fixed to the case body 25 with the insertion port 36 closed, thereby positioning and holding the batteries 34 in the storage portions 35a and 35b in an electrically connected state.

  The lid body 51 is formed in such a size that the entire insertion port 36 can be closed. A plurality of claw portions 58 that are lid-side locking portions are formed in the vicinity of the outer edge portion of the lid body 51. These claw portions 58 are for locking the lid main body 51 to the case body 25 side by being respectively locked to locking portions 59 provided on the case body 25 side. Further, a release button 60 for releasing the hook 60a from the case body 25 of the lid body 51 is provided on the design surface side of the lid body 51, that is, the surface side forming the outside of the case body 25. Yes.

  The hinge 52 includes a shaft body 61 that is slidably mounted in the front-rear direction at a position near the rear side of the lower portion of the case body 25. Both ends of the shaft body 61 are pivotally supported with respect to the case body 25. Accordingly, the lid main body 51 is rotatable with respect to the insertion port 36 and is slidable in the front-rear direction which is a direction along a predetermined direction. Then, the lid body 51 is turned to the insertion port 36 side to be in a temporarily closed state that covers a part of the insertion port 36, and is horizontally slid (slid) from the temporarily closed state to the hinge 52 side. As a result, it is positioned and fixed with respect to the insertion port 36 to be in a closed state covering the entire insertion port 36.

  The negative electrode side contact piece 54 is made of metal and is continuous in the longitudinal direction in the sliding direction of the lid body 51.

  The positive electrode side contact piece portion 56 is electrically connected to the negative electrode side contact piece portion 54 in the lid main body 51. Therefore, in the state where the two batteries 34, 34 are inserted in the respective storage portions 35a, 35b in the correct insertion direction and the lid 32 (lid body 51) is closed, the negative terminal of the battery 34 on the one storage portion 35a side. 42 and the positive electrode terminal 43 of the battery 34 on the other storage portion 35b side are electrically connected in series via a negative electrode side contact piece portion 54 and a positive electrode side contact piece portion 56, respectively. A predetermined constant voltage is generated between 47 and 48.

  Inside the positive electrode guard 55, as shown in FIG. 8, the positive electrode terminal 43 of the battery 34 inserted in the direction opposite to the correct insertion direction, that is, reversely inserted (erroneously inserted) is insulated from the guard, that is, the negative electrode side contact piece 54. A positive electrode guard groove 64 is provided as a recess for this purpose. The positive electrode guard groove 64 has a guide region 66 as an insertion portion having an outer diameter dimension sufficiently larger than the positive electrode terminal 43 and smaller than the negative electrode terminal 42, and a positive electrode having a maximum allowable dimension, that is, a maximum diameter. It has a storage area 67 as a holding portion that is large enough to accommodate the terminal 43 and smaller in width than the guide area 66. For this reason, the positive electrode guard groove 64 is formed in a shape in which large and small circles are combined along the front-rear direction. The depth dimension of the positive electrode guard groove 64 is formed to be approximately the same as the protruding dimension of the positive electrode terminal 43 from the battery body 41. Therefore, the positive electrode terminal 43 inserted into the positive electrode guard groove 64 does not go out of the positive electrode guard groove 64 in each of the temporarily closed state and the closed state.

  The guide region 66 is a space portion formed in a substantially circular shape. When the lid body 51 is temporarily closed, the guide region 66 is present from the region where the positive terminal 43 of the battery 34 that is reversely inserted into the one storage portion 35a is present. Is also formed large. The guide region 66 includes curved wall portions 66a and 66a as first guide wall portions that are curved so that the width dimension gradually decreases toward the storage region 67 side.

  Here, the region where the positive electrode terminal 43 can exist refers to the position of the positive electrode terminal 43 in a state where the battery 34 having the minimum allowable dimension has moved most in the one storage portion 35a. For this reason, the guide region 66 is formed so that the positive terminal 43 of the battery 34 reversely inserted into the one storage portion 35a is always stored in the temporarily closed state.

  On the other hand, the storage area 67 is a space formed continuously with respect to the guide area 66 on the side opposite to the hinge 52 of the lid body 51. The storage area 67 includes straight wall portions 68 and 68 as second guide wall portions that are linearly formed continuously from the guide region 66 to the opposite side of the hinge 52, and the straight wall portions 68 and 68. It is demarcated by an arcuate arc wall portion 69 which is continuous between them. Therefore, the storage area 67 is formed in a long hole shape with respect to the guide area 66.

  The straight wall portions 68 and 68 are set to have a width slightly wider than the maximum diameter dimension of the positive electrode terminal 43 of the battery 34, and are continuous with the curved wall portions 66 a and 66 a of the guide region 66. For this reason, these linear wall portions 68, 68 are used when the positive terminal 43 of the reversely inserted battery 34 stored in the guide region 66 is slid from the temporarily closed state to the closed state by sliding the lid body 51. It is formed so as to be guided (guided) relatively to the storage area 67.

  The negative electrode side contact piece 54 has the battery 34 placed in one storage portion 35a at a position along the outer side of the one linear wall 68 and the outer side of the arcuate wall 69 that is the periphery of the storage region 67. A conductive region 54a is formed as a conductive portion with which the negative electrode terminal 42 comes into contact in the closed state when correctly inserted into the connector. That is, the conduction region 54a has an arc shape, extends to the vicinity of the end of the positive electrode guard groove 64, in other words, to the vicinity of the storage region 67, and is formed along the storage region 67. The conduction region 54a is formed so as to intersect with the possible range of the negative electrode terminal 42 of the battery 34 inserted in one storage portion 35a in the correct direction.

  Here, the possible range of the negative electrode terminal 42 is the position of the negative electrode terminal 42 in a state in which the battery 34 having the minimum allowable dimension is most moved in the one storage portion 35a (the range indicated by an imaginary line in FIG. 3). 42a-42d). For this reason, the conduction region 54a is formed so that the negative electrode terminal 42 of the battery 34 correctly inserted in the one storage portion 35a always comes into contact in a closed state.

  On the other hand, the negative guard 57 is formed along the edge of the positive side contact piece 56 opposite to the hinge 52, and the positive terminal 43 can be inserted and the negative terminal 42 cannot be inserted. The notch hole 73 is partitioned. From the cutout hole 73, the positive electrode side contact piece 56 is exposed. Further, the cutout hole 73 is open on the hinge 52 side of the lid body 51. For this reason, when the battery 34 is correctly inserted into the other storage part 35b, the positive terminal 43 is inserted into the notch hole part 73 in the temporarily closed state and the closed state, and the positive side contact piece part is inserted through the notch hole part 73. 56, and when the battery 34 is reversely inserted into the other storage portion 35b, the negative terminal 42 contacts the negative guard 57 in the temporarily closed state and the closed state, and the negative terminal 42 and the positive side contact piece 56 It is comprised so that contact may be prevented.

  Next, the operation of the above embodiment will be described.

  When the battery 34 is stored in the one storage portion 35a, the positive electrode terminal 43 side is inserted from the insertion port 36 with the bottom portion side of the one storage portion 35a. Further, when the battery 34 is stored in the other storage portion 35b, the negative electrode terminal 42 side is inserted from the insertion port 36 as the bottom side of the other storage portion 35b.

  As a result, the positive terminal 43 of the battery 34 inserted into one storage part 35a comes into contact with the one battery contact piece 47 and is conducted, and the negative terminal 42 of the battery 34 inserted into the other storage part 35b is connected to the other. The battery contacts with the battery contact piece 48 and becomes conductive.

  Next, when the lid 32 (lid body 51) is rotated to the case body 25 side, each claw portion 58 comes into contact with each locking portion 59 and is temporarily closed.

  In this state, when the lid 32 (lid body 51) is slid toward the hinge 52, the claw portion 58 is locked to the case body 25 side with the lid body 51 closing the entire insertion port 36, and the lid 32 is closed. The (lid body 51) is positioned and fixed with respect to the insertion slot 36, and the batteries 34, 34 are held in the storage portions 35a, 35b. In this state, as shown in FIG. 3, the negative electrode terminal 42 of the battery 34 inserted into one storage portion 35a comes into contact with the conduction region 54a of the negative electrode side contact piece portion 54, and the other storage portion 35b. The positive electrode terminal 43 of the battery 34 inserted in is inserted into the cutout hole portion 73 and is brought into contact with the positive electrode side contact piece portion 56 to be conducted.

  On the other hand, as shown in FIG. 1 (b), the lid 32 (lid body 51) is rotated toward the case body 25 in a state where the battery 34 is mistakenly inserted in the one storage portion 35a, so that the temporarily closed state is obtained. Then, as shown in FIG. 1A, the positive terminal 43 of the battery 34 is placed in any position in the guide region 66.

  When the lid 32 (lid body 51) is slid to the hinge 52 side (arrow d direction) as shown in FIG. 2 (b) from this temporarily closed state, as shown in FIG. 2 (a), the guide The positive electrode terminal 43 inserted into the region 66 is drawn between the straight wall portions 68 and 68 by the curved wall portions 66a and 66a of the positive electrode guard groove 64, and further into the storage region 67 along the straight wall portions 68 and 68. By being pulled in and held at a predetermined position in the storage area 67, the battery 34 is held in one storage part 35a, and the positive terminal 43 does not contact the negative contact piece 54.

  As described above, in the above-described embodiment, when the battery 34 is reversely inserted into the one storage portion 35a, the battery 34 is moved when the lid 32 (lid body 51) is slid from the temporarily closed state to the closed state. The positive terminal 43 can be guided and held in a predetermined storage area 67. For this reason, when the battery 34 having the battery body 41 of the minimum allowable dimension is erroneously inserted into the one storage portion 35a, the positive electrode terminal 43 can be positioned with respect to the negative electrode side contact piece 54, and the negative electrode side contact piece 54 Since it does not move in the vicinity, it is possible to reliably prevent the positive terminal 43 from conducting illegally to the conduction region 54a.

  Further, by preventing such unauthorized conduction, it is possible to prevent an unfavorable influence on a circuit that uses the battery box 24 as a power source, such as an image processing circuit of the camera 21.

  In addition, since the negative electrode side contact piece 54 and the positive electrode guard 55 can be easily configured by changing the shape of the same component as the conventional one, it is possible to prevent an increase in cost due to an increase in the number of components and an increase in manufacturing man-hours. .

  Further, by forming the conduction region 54a of the negative electrode side contact piece portion 54 along a part of the periphery of the storage region 67 having a relatively small outer diameter in the positive electrode guard groove 64, the entire negative electrode side contact piece portion 54 is formed. The area of can be taken widely. For this reason, when the battery 34 is correctly inserted into one storage portion 35a, a large contact area between the negative electrode terminal 42 of the battery 34 and the conduction region 54a of the negative electrode side contact piece portion 54 can be secured. The conduction region 54a can be reliably brought into contact with, and the reliability of conduction can be improved.

  In the above-described embodiment, the battery box 24 can be applied to any electric device that requires the battery to be inserted in a predetermined direction, in addition to being applied to the camera 21.

  In addition, the battery box 24 is provided with the storage portions 35a and 35b. However, when the battery box 24 corresponds to one having one storage portion, for example, one storage portion 35a and the negative electrode side contact piece portion 54 of the lid 32 are provided. And the structure of the positive electrode guard 55 may be applied. Furthermore, even if the battery box 24 includes three or more storage units, the lid 32 can be used correspondingly.

  Moreover, although the battery 34 has been described as being AA size, for example, a battery of other sizes such as single size or single size can be handled. Further, the battery 34 can be a button type battery, for example. However, since a button type battery usually has a small negative electrode diameter, the relationship between the positive electrode terminal and the negative electrode terminal is reversed from that of the above embodiment, that is, the first terminal is the positive electrode terminal and the second terminal is the negative electrode terminal. Need to design.

  As long as the lid 32 is at least in a closed state by sliding, the configuration for making the temporarily closed state can be arbitrarily selected.

  The positive electrode guard 55 can be formed not only by attaching a separate part to the lid body 51 but also integrally with the lid body 51.

  The present invention can be applied, for example, as a battery storage device and a battery lid device included in a digital still camera.
