Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector with a switch, and particularly to connecting an antenna to a main body of a communication device in an ultra-high frequency band, for example, a band of several hundred MHz to several GHz, or another line in a transmission line in an electronic device. The present invention relates to a connector with a switch that is used when connecting a connector and the like and that can switch signals by the connection.

[0002]

2. Description of the Related Art As a connector of this type, a fixed connection piece and a movable connection piece connectable to the fixed connection piece are arranged in a case, and another male connector is inserted into the case to displace the movable connection piece. There is known a configuration in which a fixed connection piece is pressed into contact with the fixed connection piece, or a movable connection piece that is pressed in advance is separated from the fixed connection piece to perform a switch operation.

[0003]

However, in the conventional connector with a switch, the male connector is inserted from the outside along the movable connecting piece to displace the male connector to perform the switch operation. Depending on the case, it may be necessary to insert the male connector to be connected from the direction intersecting the movable connecting piece. In particular, for connectors that are connected by flat bonding to the circuit board of electronic equipment, fixed connection pieces and movable connection pieces that are generally located along the circuit board are made to project in a plane from both sides of the case, and the internal movable connection It is easy to have a structure in which the male connector is inserted from above toward the bottom toward one side,
It has been desired to provide a connector with a switch which has a simple structure and can be used in such a manner.

Further, in the connector with a switch for switching the signal of the ultra-high frequency band, it is necessary to keep the fixed connection piece and the movable connection piece in a reliable contact state, and in addition to simple pressure contact, special measures are required. The present invention has been made in order to solve such a conventional drawback, and a connector to be connected can be inserted toward a movable connecting piece, and a connector with a simple switch for performing a switch operation by the inserted connector. For the purpose of provision. Another object of the present invention is to provide a connector with a switch that can obtain a reliable contact state between the fixed connection piece and the movable connection piece.

[0005]

In order to solve such a problem, the present invention supports a fixed connection piece on a case, and a movable connection piece is supported on the case so that its open end side is displaceable. A branch connection piece to which an external connector is connected is erected on the movable connection piece on the pressure contact surface side with the fixed connection piece, and there is no external pressure along the branch connection piece. In this state, the movable connecting piece is formed so as to be elastically pressed against the fixed connecting piece and to be separated from the fixed connecting piece against the elastic force by the pressure from the outside. Further, in the present invention, it is preferable that the movable connecting piece is curved so as to urge the fixed connecting piece.

[0006]

According to the present invention having such means, by connecting the external connector to the branch connecting piece and pressing the movable connecting piece directly or indirectly, the movable connecting piece is moved in the connected state. When the connection piece separates from the fixed connection piece and the external connector is removed, the movable connection piece returns to its original state, and the fixed connection piece is pressure-contacted to establish conduction. Further, in the configuration in which the movable connection piece is formed in a curved shape, a stress acts on the movable connection piece such that the movable connection piece slides on the fixed connection piece at the time of pressure contact with the fixed connection piece.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view showing an embodiment of a connector with a switch according to the present invention. In FIG. 1, a case 1 is formed by covering a flat insulating substrate 3 with a conductive cover 5 and integrating it, and a recess 7 formed in the substrate 3 includes a fixed connection piece 9 and a movable connection piece 11 which will be described later. A switch mechanism is formed. The fixed connection piece 9 is formed by bending an elongated elastic conductive piece in a stepwise manner on the way, supporting the bent portion by the substrate 3, and projecting one tip end side from the lower side surface of the substrate 3 to form the external connection terminal 9a. The other tip side is projected to the upper part in the recess 7 to form the fixed contact 9b.

The movable connecting piece 11 has an elastic conductive piece longer than the fixed connecting piece 9 supported by the substrate 3 at a position facing the fixed connecting piece 9, and one tip side of the movable connecting piece 11 from the lower side surface of the substrate 3. The external connection terminal 11 a is made to project, and the other end side is made to project into the recess 7. The movable connection piece 11 is a portion located in the recessed portion 7, and is a branch connection piece 15 defined by a U-shaped slit 13 formed along the longitudinal direction.
(See FIG. 2), the branch connection piece 15 is shown in FIG.
As shown in the figure, it is stood up and bent, and the tip is slightly curved.

The movable connecting piece 11 is curved and formed in the recess 7 so as to bulge in the rising direction of the branch connecting piece 15, and the tip portion of the movable connecting piece 11 is fixed in the recess 7 (fixed contact 9b).
Is pressed against the lower surface in the figure. That is, the movable connection piece 11
Is curvedly formed in the recess 7 toward the pressure contact surface side (upper side surface in FIG. 1) with the fixed connection piece 9, so that the tip end thereof is in pressure contact with the lower surface of the fixed connection piece 9 and the fixed connection piece 9 ( A stress is applied so as to slide on the lower surface of the fixed contact 9b). The cover 5 forming the case 1 integrally has a tubular portion 17 that surrounds the branch connection piece 15, and the inside of the tip of the tubular portion 17 is a small diameter portion 19.

A pressing cylinder 21 surrounding the branch connecting piece 15 is fitted in the cylindrical portion 17. This pressing cylinder 21 is made of an insulating material, and one end has a small outer diameter so as to be fitted into the small-diameter portion 19 of the cylinder portion 17 so as not to come off, while the other end extends to the movable connecting piece 11. Although the movable connector 11 is displaced by being pressed by the insulating layer 27 of the male connector 25, which will be described later, and the movable connector 11 is pushed down, the elastic force of the movable connector 11 is normally urged in the direction of the small diameter portion 19. ing. As shown in FIGS. 1 and 4, the hollow portion 21 a of the pressing cylinder 21 has a central conductor 27 of the male connector 25.
Is an insertion hole that is inserted from the tip side, but one side (right side in FIG. 1) of the pressing cylinder 21 becomes thin and the branch connection piece 1
There is play that can be displaced so that 5 opens to the external connection terminal 11a side. In addition, as shown in FIG. 6, which will be described later, the pressing cylinder 21 is configured such that the cylindrical portion 17 is fitted in a recess 23 formed along the axial direction so as not to rotate.

Next, as shown in, for example, FIG. 5, a usage example of the connector with a switch according to the present invention described above is such that the center conductor 27 is supported in the conductive cover 29 through the insulating layer 31, and the conductive cover 29 is supported. An example will be described in which the insulating layer 31 is projected from the front end surface (lower end surface in the drawing) of the above and the male connector 25 having the central conductor 27 projected longer than this is connected. When the central conductor 27 protruding from the conductive cover 29 is inserted into the hollow portion 21a of the pressing cylinder 21 and press-fitted between the branch connection piece 15 and the pressing cylinder 21 itself, the central conductor 27 is inserted.
Slides in contact with the tip of the branch connection piece 15 to push it apart, and the tip of the insulating layer 31 is inserted into the pressing tube 2 during insertion.
Since it is pushed down by hitting 1, the movable connecting piece 11 is pushed down by the pressing cylinder 21 against the urging force thereof.

As a result, the tip of the movable connecting piece 11 falls apart from the fixed connecting piece 9 and the connection between the movable connecting piece 11 and the fixed connecting piece 9 is broken. In the process, the central conductor of the male connector 25 is cut off. The connection between the movable connection piece 11 and the fixed connection piece 9 is cut off after the connection state of 27 and the branch connection piece 15. That is, as shown in FIG.
Is the A terminal, the movable connection piece 11 is the B terminal, and the branch connection piece 15 is the C terminal.
Terminal A, B terminal and C terminal are connected, and then A terminal and B terminal
The connection between the terminals is cut off, and the B and C terminals are connected.

As described above, in the connector with a switch of the present invention, the connector 25 is inserted in such a direction as to intersect with the movable connecting piece 11. For example, as shown in FIG. Even in the connection configuration, the connector 25 can be easily inserted and connected from above to enable the switch operation. Moreover, since the switch mechanism is simply formed by the fixed connection piece 9, the movable connection piece 11, and the branch connection piece 15 formed upright from the fixed connection piece 9, the configuration is extremely simple, inexpensive, and easy to miniaturize.

Further, since the movable connecting piece 11 is curved in the concave portion 7 toward the fixed connecting piece 9 side (upper side in the drawing), the tip end of the movable connecting piece 11 slides on the lower surface of the fixed connecting piece 9. The contact state between the fixed connection piece 9 and the movable connection piece 11 by pressing is extremely reliable and stable. Furthermore, if a connector 25 is used that pushes down the pressing cylinder 21 after the central conductor 27 contacts the branch connection piece 15, the connector 25 is in a state of conducting to the branch connection piece 15, that is, the movable connection piece 11 and the fixed connection piece 9. Since the connection with the fixed connection piece 9 is cut off after passing through the movable connection piece 1 during the switch operation by the connector 25,
1 does not become open.

Therefore, for example, when an ultra-high frequency signal is applied from the fixed connection piece 9 side with the movable connection piece 11 side as a load, fluctuation of the load seen from the fixed connection piece 9 side can be suppressed during the switch operation by the connector 25. This makes it possible to reduce the signal reflection and spurious emission.
Therefore, as shown in FIG. 8, the circuit element 3 of the electronic device is
Even in the configuration in which the switch-equipped connector 41 of the present invention is inserted in series in the middle of 7 and 39 and the test signal is switched and applied from the branch connection piece (C terminal) 15 of the switch-equipped connector 41, the circuit is opened when the test signal is switched and applied. Therefore, the inspection based on the test signal can always be performed in a stable operation state.

By the way, in the above-mentioned embodiment, the movable cylinder 11 is indirectly pushed down by the pressing cylinder 21 along the branch connecting piece 15 from the outside, but the present invention is not limited to this. For example, the structure may be such that the branch connection piece 15 itself is pushed down and the movable connection piece 11 is pushed down,
Even if the movable connecting piece 11 is indirectly pushed down, the pushing member is not limited to the pressing cylinder 21, but may be any member that pushes down the movable connecting piece 11 along the branch connecting piece 15 from the outside.

However, as described above, the male connector 2
If the central conductor 27 of No. 5 is configured to be in sliding contact with the branch connection piece 15, the mutual electrical contact state will be ensured.
Furthermore, the branch connection piece 15 in the present invention is the movable connection piece 1.
It is not necessary to provide the slit 13 in 1 to stand up so as to cut and raise it, and a separate one may be set upright on the movable connection piece 11, but it is bent from the movable connection piece 11 as in the above-described embodiment. If it is installed upright, the number of parts is small and it is easy to manufacture and inexpensive. The connector to be inserted and connected to the switch-equipped connector of the present invention can be implemented in various configurations, and includes, for example, a configuration in which a part of the antenna is used as a connector in addition to the connector in the narrow sense.

[0018]

As described above, in the connector with a switch of the present invention, the case is made to support the fixed connection piece, and the case is made to support the movable connection piece such that the open end side is displaceable and is pressed against the fixed connection piece. A branch connection piece to which an external connector is connected is erected on the fixed connection piece side of the movable connection piece, and the fixed connection piece is elastically attached to the fixed connection piece without external pressure along the branch connection piece. Since the movable connecting piece was formed so as to be pressed against the body and to be separated from the fixed connecting piece against its elastic force by the pressure from the outside, insert the connector to be connected toward the movable connecting piece to operate the switch. Is possible. Moreover,
Since substantially one fixed connection piece and one movable connection piece can be used, the structure is simple and inexpensive. Further, in the configuration in which the movable connection piece is curved, stress acts on the movable connection piece to slide on the fixed connection piece when the fixed connection piece is pressed, so that the fixed connection piece and the movable connection piece can be reliably and A stable contact state can be obtained.
