Referring to fig. 1 to 3, a connector assembly 10 according to an embodiment of the present invention includes a first connector 20 and a second connector 30. In the present embodiment, the first connector 20 is a device-mounted connector mounted on an electronic device (not shown). In addition, the second connector 30 is connected to the front end of the cable 50. However, the present invention is not limited thereto. For example, the first connector 20 may be configured to be connected to various cables. The second connector 30 may be mounted on an electronic device or a circuit board.
As understood from fig. 1,2, 5 and 7, the first connector 20 and the second connector 30 can be fitted to each other in the front-rear direction. More specifically, the second connector 30 can be fitted to the first connector 20 from the rear. In the present embodiment, the front-rear direction is the X direction. The X direction is forward and the +x direction is backward.
As shown in fig. 4, the first connector 20 has at least one first contact 22, a plurality of additional contacts 24, and a first housing 26. In the present embodiment, the number of the first contactors 22 is two. In addition, the number of additional contactors 24 is four. However, the present invention is not limited thereto. The first connector 20 may be one or three or more. The number of the additional contactors 24 is not particularly limited, and may be omitted.
As shown in fig. 4, the first contact 22 and the additional contact 24 are held by the first housing 26. In the present embodiment, the first contactor 22 and the additional contactor 24 are respectively made of metal. In more detail, the first contact 22 and the additional contact 24 are formed by punching a metal plate, respectively. The first case 26 is made of an insulator, for example, an insulating resin. In the present embodiment, the first connector 20 is insert molded together with the first contact 22 and the additional contact 24. In addition, the additional contactor 24 is not directly related to the present invention, and thus, a description thereof will be omitted hereinafter.
As shown in fig. 4 and 6, the first contactors 22 are respectively plate-shaped and extend in the front-rear direction. However, the present invention is not limited thereto. The shape of the first contactor 22 is not particularly limited, and may be at least partially cylindrical or cylindrical.
As shown in fig. 6, each of the first contactors 22 has a first connection portion 220, a first held portion 222, a wide portion 224, and a first contact portion 226, respectively. In the present embodiment, the first connecting portion 220, the first held portion 222, the wide portion 224, and the first contact portion 226 are arranged in this order in the front-rear direction.
As shown in fig. 6, the first connection portion 220 of the first contactor 22 has a substantially square shape when viewed in a lateral direction orthogonal to the front-rear direction. In the present embodiment, the lateral direction is the Y direction.
As shown in fig. 6, the first held portion 222 of the first contactor 22 has a rectangular shape long in the front-rear direction, and extends rearward from the first connection portion 220. The first held portion 222 has a smaller size than the first connecting portion 220 in the up-down direction orthogonal to both the front-back direction and the lateral direction. In the present embodiment, the vertical direction is the Z direction. The +Z direction is upward and the-Z direction is downward.
As shown in fig. 6, the wide portion 224 of the first contactor 22 extends rearward from the first held portion 222. In the up-down direction, the size of the wide portion 224 is larger than that of the first held portion 222. The rear portion of the wide portion 224 is tapered so as to be reduced in size in the up-down direction as going rearward.
As shown in fig. 6, the first contact portion 226 of the first contactor 22 extends rearward from the wide portion 224. In the up-down direction, the size of the first contact portion 226 is smaller than the size of the wide portion 224. The rear portion of the first contact portion 226 is tapered so as to be reduced in size in the up-down direction as going backward.
As understood from fig. 4 and 6, the first held portion 222 is held by the first housing 26. In the present embodiment, not only the first held portion 222 but also the first connecting portion 220 and the wide portion 224 are partially held by the first housing 26, respectively. However, the present invention is not limited thereto. The first housing 26 may hold the first held portion 222 at least partially.
As shown in fig. 6, a recess 228 recessed upward is formed in the front-rear direction center of the wide portion 224. Due to the recess 228, a part of the wide portion 224 constitutes a first locking portion 230 protruding downward in the up-down direction. In other words, the first contactor 22 has the first locking portion 230 protruding downward. In the present embodiment, the first locking portion 230 is located between the first contact portion 226 and the first held portion 222 in the front-rear direction. The first locking portion 230 has a first locking surface 232 that faces forward in the front-rear direction.
Referring to fig. 9 to 11, the second connector 30 includes at least one second contactor 32 and a second housing 36. In the present embodiment, the number of the second contactors 32 is two. The number of second contacts 32 corresponds to the number of first contacts 22 of the first connector 20. The second contactors 32 are each made of metal. In more detail, the second contactors 32 are formed by punching and bending one metal plate, respectively. The second housing 36 is formed of an insulator, for example, an insulating resin. The second housing 36 holds the second contactor 32.
As shown in fig. 11 and 12, the second contactor 32 has a second connection portion 320, a second held portion 330, and a pair of second contact portions 340, respectively. The second connection portion 320 has a first tube portion 322 and a second tube portion 324, and is connected to the cable 50. The second held portion 330 is located forward of the second connecting portion 320, and has a front portion 332 and a rear portion 334.
As can be understood from fig. 9 and 10, the rear portion 334 of the second held portion 330 is formed in a quadrangular tube shape and extends in the front-rear direction. A blocked portion (fixed portion) 342 is provided on the upper surface of the rear portion 334. The front portion 332 of the second held portion 330 extends forward from the rear portion 334. The front 332 opens upwardly, forwardly and laterally.
As shown in fig. 12, the second contact portions 340 extend laterally inward and obliquely forward from the rear portion 334 of the second held portion 330, respectively. The second contact portions 340 have contact points, respectively. The contact points are opposed to each other in the lateral direction. As shown in fig. 8, the second contact portion 340 contacts the first contact portion 226 of the first contactor 22 in a fitted state in which the first connector 20 and the second connector 30 are fitted to each other. In more detail, the contact point of the second contact portion 340 is in contact with the first contact portion 226 of the first contactor 22.
As shown in fig. 9 and 10, the second case 36 has a substantially rectangular parallelepiped shape that opens forward and backward. More specifically, the second housing 36 has a bottom plate portion 360, a pair of side plate portions 362, a middle plate portion 364, and an upper plate portion 366. The second housing 36 has a pair of engaging portions (a hooking portion, a fixing portion) 370 at an upper portion thereof. The second housing 36 has a pair of second locking portions 380 and supporting portions 384 corresponding to the second locking portions 380, respectively, at a lower portion thereof.
As understood from fig. 9 and 14, the stopper portions 370 are lance-shaped locking portions (lance/catches) (lance), respectively. More specifically, the stopper 370 is formed in a cantilever shape and extends obliquely downward and forward. The stopper 370 is elastically deformable. The stopper 370 has a stopper surface 372 facing obliquely upward and forward. The stopper surface 372 is displaceable at least in the up-down direction due to elastic deformation of the stopper portion 370. However, the present invention is not limited thereto. The catch portion 370 may be formed as a simple recess or projection.
As will be understood from fig. 10 and 14, the support portions 384 are each formed in a cantilever shape and extend forward. The supporting portions 384 support the corresponding second locking portions 380. The second locking portion 380 is located at the front end of the supporting portion 384. The second locking portion 380 has a second locking surface 382 that faces rearward in the front-rear direction. In the present embodiment, the second engagement surface 382 is formed as an inclined surface that extends obliquely upward and rearward from the support portion 384. The second locking surface 382 may be a single plane or a curved surface. The second engagement surface 382 may be a plurality of continuous flat surfaces or curved surfaces, or a combination of flat surfaces and curved surfaces. The second locking surface 382 contacts the first locking surface 232 (see fig. 6) at an acute angle in a fitted state in which the first connector 20 (see fig. 6) and the second connector 30 are fitted. Accordingly, when the second connector 30 is pulled rearward with respect to the first connector 20, the second connector 30 is made not to easily separate from the first connector 20. The support 384 is elastically deformable. The second locking portion 380 is displaceable at least in the up-down direction due to elastic deformation of the supporting portion 384.
As shown in fig. 14, in the present embodiment, the stopper portion 370 is located rearward of the support portion 384 in the front-rear direction. However, the present invention is not limited thereto. The blocking portion 370 may be located at a position at least partially overlapping the supporting portion 384 in the front-rear direction. With this configuration, the second connector 30 can be reduced in size in the front-rear direction.
As will be understood from fig. 9, 10 and 14, in the present embodiment, the stopper portion 370 is provided on the upper plate portion 366, and the support portion 384 is provided on the bottom plate portion 360. However, the present invention is not limited thereto. The blocking portion 370 may be provided on the bottom plate portion 360, and the supporting portion 384 may be provided on the upper plate portion 366. Alternatively, the blocking portion 370 and the supporting portion 384 may be provided on the side plate portion 362. In either case, the stopper 370 and the support 384 are provided at different positions from each other in a plane orthogonal to the front-rear direction. The purpose is to achieve both downsizing and strength securing of the second housing 36.
As shown in fig. 12 and 14, the second housing 36 has a pair of receiving portions 386. The receiving portions 386 correspond to the second contactors 32, respectively. In addition, the receiving portion 386 receives at least the first contact portion 226 of the first contact 22 in a fitted state in which the first connector 20 and the second connector 30 are fitted to each other. The bottom plate portion 360, the side plate portion 362, the middle plate portion 364, and the upper plate portion 366 of the second housing 36 constitute a peripheral wall portion surrounding the accommodating portion 386. As understood from fig. 13, the peripheral wall portion and the support portion 384 surround the accommodation portion 386 in a plane orthogonal to the front-rear direction. As understood from fig. 6 and 8, the receiving portions 386 receive the corresponding second contactors 32, respectively. In the present embodiment, the second locking portion 380 protrudes into the corresponding receiving portion 386.
As shown in fig. 12 to 14, the second housing 36 further has a guide portion 388 and a guide portion 390 corresponding to the receiving portion 386, respectively. The inducing portion 388 is formed of three flat surfaces provided on the upper plate portion 366, the side plate portion 362, and the middle plate portion 364. These planes intersect the front-rear direction. This is to facilitate insertion of the first contact portion 226 of the first contactor 22 into the receiving portion 386. The guide portion 390 is located rearward of the inducing portion 388 and extends rearward in the front-rear direction. In the front-rear direction, the guide 390 is preferably large in size. This is to suppress tilting of the first contact portion 226 inserted into the receiving portion 386.
As shown in fig. 12, the guide portion 390 has a pair of guide side surfaces 392 opposed to each other so as to be laterally apart (spaced apart). In the lateral direction, the dimension between the guide sides 392 is slightly larger than the dimension of the first contact portion 226 (see fig. 4). This is to allow insertion of the first contact portion 226. In addition, the dimension between the guide sides 392 is smaller than the dimensions of the second locking portion 380 and the support portion 384 in the lateral direction. This is because, in order to secure the strength of the support portion 384 and the second locking portion 380, their sizes are increased in the lateral direction.
As will be appreciated from fig. 14 and 15, the second contactor 32 is inserted into the receiving portion 386 of the second housing 36 from the rear. At this time, the blocked portion 342 elastically deforms the blocking portion 370 and moves forward of the blocking portion 370. When the blocked portion 342 moves forward of the blocked portion 370, the blocking surface 372 is located rearward of the blocked portion 342 due to the restoring force of the blocked portion 370. The blocking surface 372 located rearward of the blocked portion 342 prevents the second contactor 32 from moving rearward relative to the second housing 36.
As shown in fig. 4 and 15, when the second contactor 32 is inserted into the receiving portion 386 of the second housing 36, the second held portion 330 contacts the inner surface of the receiving portion 386 of the second housing 36 and is held by the second housing 36. The second contact portion 340 is located in the receiving portion 386.
As understood from fig. 6 and 8, when the first connector 20 and the second connector 30 are fitted to each other, the first contact portion 226 of the first contactor 22 is received in the receiving portion 386. At this time, the guide portion 388 and the guide portion 390 of the second housing 36 guide the accommodation of the first contact portion 226 into the accommodation portion 386. The first contact portion 226 received in the receiving portion 386 is in contact with and electrically connected to the second contact portion 340 located in the receiving portion 386. In this way, in the mated state in which the first connector 20 and the second connector 30 are mated with each other, the first contact portion 226 and the second contact portion 340 are positioned in the receiving portion 386, and protected from the outside by the second housing 36.
As can be understood from fig. 6, when the first connector 20 and the second connector 30 are fitted to each other, the wide portion 224 (the first locking portion 230) is also accommodated in the accommodating portion 386. When the first locking portion 230 enters the receiving portion 386, it abuts against the second locking portion 380, and presses the second locking portion 380 downward. The second locking portion 380 moves downward due to the elastic deformation of the supporting portion 384. When the first locking surface 232 moves rearward than the second locking surface 382, the first locking surface 232 is positioned rearward of the second locking surface 382 due to the restoring force of the supporting portion 384. The first locking portion 230 is positioned in the receiving portion 386, and the first locking surface 232 faces the second locking surface 382. When the second connector 30 is to be moved rearward relative to the first connector 20, the first engagement surface 232 abuts against the second engagement surface 382, thereby preventing the second connector 30 from being disengaged. This can maintain the fitted state of the first connector 20 and the second connector 30.
As can be understood from fig. 6 and 8, the front end of the second housing 36 constitutes an abutment 396 that abuts against the first housing 26. The tip of the second locking portion 380 functions as a part of the abutting portion 396. The first housing 26 has an abutted portion 262 opposed to the abutting portion 396 of the second housing 36. In the present embodiment, the abutted portion 262 is the rear surface of the first housing 26.
As can be understood from fig. 2, 3, and 6, the first engagement surface 232 is spaced apart from the abutted portion 262 in the front-rear direction and is opposed to the front edge 229 of the recess 228 in the non-fitted state. In the present embodiment, the front edge 229 of the recess 228 of the first contact 22 is formed on the same plane as the abutted portion 262 of the first housing 26. Accordingly, the front edge 229 of the recess 228 of the first contact 22 may be considered as part of the abutted portion 262. Therefore, the first engagement surface 232 can be opposed to the abutted portion 262. The front edge 229 of the recess 228 is buried in the first housing 26 and may be located forward of the rear surface of the first housing 26 in the front-rear direction. In this case, the first engagement surface 232 is opposed to the rear surface of the first housing 26. Therefore, in this case, the first locking surface 232 can be said to face the abutted portion 262. In this way, the first engagement surface 232 faces the abutted portion 262. When the first connector 20 and the second connector 30 are not fitted, nothing exists between the first locking portion 230 and the abutted portion 262.
As can be understood from fig. 6, in the fitted state in which the first connector 20 and the second connector 30 are fitted to each other, the second locking portion 380 is located between the abutted portion 262 and the first locking surface 232. The second locking portion 380 protrudes into the receiving portion 386, and is engaged with the first locking portion 230 of the first contactor 22. In this way, the first locking portion 230 of the first contactor 22 and the second locking portion 380 of the second housing 36 function as a fitting locking mechanism. The fitting locking mechanism is not a structure that locks the housings to each other. Therefore, according to this structure, the connector assembly 10 in the up-down direction can be made smaller in size than the connector assembly of patent document 1. The second locking portion 380 is not located further forward than the abutting portion 396 in the front-rear direction. According to this structure, the connector assembly 10 can be reduced in size in the front-rear direction.
The embodiments of the present invention have been described above specifically, but the present invention is not limited to the embodiments, and various modifications and alterations can be made. For example, in the above embodiment, the first locking portion 230 is formed by forming the recess 228 in the wide portion 224, and a protruding portion protruding downward in the vertical direction may be provided as the first locking portion 230 in a connecting portion (corresponding to the wide portion 224) connecting the first connecting portion 220 and the first contact portion 226.
In the above embodiment, the first contactor 22 has a plate shape, but may be a cylinder or a cylindrical shape. In this case, the first contactor 22 may be formed in a structure in which a plurality of cylinders or cylinders having different diameters are continuous. In this case, the first locking portion 230 may be provided by forming a recess or a hole (corresponding to the recess 228), or may be provided by forming a protrusion.
In the above embodiment, the first locking portion 230 is not displaceable in the vertical direction. However, as shown in fig. 16, the first locking portion 230 supported by the cantilever-like support portion 384A may be provided so that the first locking portion 230 is displaceable at least in the up-down direction. In this case, the second locking portion 380 may or may not be displaceable in the up-down direction. In the present invention, at least one of the first locking portion 230 and the second locking portion 380 may be supported by the support portion 384 and/or 384A, and may be displaceable in the up-down direction by elastic deformation of the support portion 384 and/or 384A. In addition, when both the first locking portion 230 and the second locking portion 380 are movable in the up-down direction, the amount of deformation of each of the support portions 384 and 384A when the first connector 20 is engaged with the second connector 30 can be reduced. On the other hand, in the case where only one of the first locking portion 230 and the second locking portion 380 is movable in the vertical direction, the structure is simple, and the relative positional accuracy of the first locking portion 230 and the second locking portion 380 can be improved.
