DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding type multi-pole connector in which flat joint surfaces are slid and disengaged from each other, and a number of contacts exposed on both joint surfaces are brought into contact with each other. .

[0002]

2. Description of the Related Art Conventionally, for example, as shown in FIG. 12, a video camera 1 is fitted to an adapter 2 to electrically connect a power supply and other circuits between the two via connectors 3 and 4. A device that connects to the television receiver 6 via a TV has been developed.

[0003] Also, as shown in FIG.
Is electrically connected to the adapter 2 via a cable 7. Connectors 3 a and 4 a are connected to both ends of the cable 7, and one connector 4 a is connected to the connector 3 of the video camera 1. Further, the other connector 3 a is fitted to the connector 4 of the adapter 2.

The connectors 3 and 4 need to have a function of holding the video camera 1 on the adapter 2 in addition to the electrical connection between the contacts. For this reason, as shown in FIG. The connector 4 is provided integrally with fitting ribs 9, 9 on both sides of the joining surface 8, and the guide concave grooves 11, into which the fitting ribs 9, 9 are inserted, on both sides of the video camera 1 side joining surface 10. The video camera 1 is mounted on the adapter 2 by fitting and sliding the two, and necessary circuits are electrically connected.

In addition, since the contacts on the adapter 2 side particularly include a live part such as a power supply, a cover 12 is provided so that these parts are not exposed when the video camera 1 is removed. As shown in FIG. 15, the cover 12 pushes the contact spring piece 13 constituting the contact so as to be pulled down to a position lower than the surface of the joint surface 14.

[0006]

In the conventional device as described above, the cover is operated so as to deflect the contact spring in the pulling-in direction.
There has been a problem that the stability of contact deteriorates in a short period of time.
Further, in the conventional device, when the number of contacts that come into contact with each other is small, a sufficient space can be taken. Therefore, a structure in which the contact spring 21 is mechanically pulled in by the movement of the cover 22 can be adopted. When the number of points increases, there is a problem that the size must be increased due to the necessity of increasing the contact interval.

Further, in the conventional device, when the connector is not joined, the cover 22 is easily opened by an external force. For example, when the cover 22 is pushed in the sliding direction with a finger, the live portion protrudes, and the contact between the contacts is removed. However, there were problems such as short-circuiting with fingers.

In view of such a conventional problem, the present invention can be downsized even when a large number of contacts are provided in a narrow space, and when the connector is not joined without fatigue of the contact spring.
It is an object of the present invention to provide a highly reliable slide type multi-pole connector in which the outside is completely covered so that stable contact can be obtained for a long period of time and the cover is not easily opened by an external force.

[0009]

The features of the present invention for solving the conventional problems as described above and achieving the intended object are as follows.
The male connector is disengaged from each other by sliding with respect to the female connector, and a large number of contacts are exposed on the mutually sliding joint surfaces of the connectors. In the slide-type multipolar connector, the male connector is provided integrally with a pair of fitting ribs having both side edges of a joint surface protruding in an extending direction in a connector insertion / removal direction. On both sides of the joint surface, a guide groove for inserting the fitting rib of the male connector is provided in the connector sliding direction, and both sides of the female connector are slidable in the guide groove. A contact cover that is fitted and urged by a spring on the side that covers the surface of the contact is provided, and within the guide groove, at a position that covers the contact surface. Serial contactors cover slide incapable locked, by a fitting rib of the male connector lies in having a cover locking pawl spring piece in which the locking is released.

Further, the spring piece with the cover locking claw has a cover locking claw integrally at the tip end thereof, and the intermediate length portion and the fitting rib of the male connector are provided at the operating end position of the fitting side of both connectors. A detent concave portion and a convex portion that fit each other may be provided.

[0011]

In the slide type multipolar connector according to the present invention, when the male connector is not fitted, the contact cover of the female connector is pushed out by a spring and covers the outer surface of the contact. In this state, the movement of the contact cover in the opening direction is restricted by the spring piece with the cover locking claw. From this state, when the male connector slides by fitting the fitting rib on the side edge of the male connector into the guide concave groove of the female connector, the spring piece with the claw is engaged with the contact cover by the fitting rib. The contact cover is pushed to the release side, the opening of the contact cover is restricted, and the contact cover is pushed open together with the male connector. Then, when the connectors are fitted to the fitting-side slide ends, the contacts of the connectors come into contact with each other, and the circuit is electrically connected. Also, by removing the male connector from this state and sliding it in the direction,
The contactor cover is pushed out together with the slide of the male connector by the spring, and the male connector is pulled out, so that the spring piece with the cover locking claw returns to the original position,
The contact cover is prevented from opening (claim 1).

[0012] Further, by providing a concave portion and a convex portion for engaging with each other in the spring piece with the cover locking claw and the fitting rib of the male connector, the male connector is completely located at the slide end position in the fitting direction. This informs the worker of the insertion, and also exerts the effect of preventing the male connector from coming off (claim 2).

A protrusion 36b is fitted in the guide groove 30, and is guided by the groove to be separated from the shielding position on the contact 23B and from the contact 23B and housed in the casing 21B. The slider is slid between the open position and the trailing edge side is pressed by a spring 33B and is urged to the shielding position side.

Spring pieces 35, 35 with cover locking claws for restricting the slide of the contact cover 26B are provided in both the guide concave grooves 30, 30 of the female connector B.
The two spring pieces 35, 35 are cantilevered, are formed integrally with the casing 21B so as to face each other, and have locking claws 35a for preventing the cover from opening at the distal ends. Is integrally formed with a protrusion 35b that serves both as a moderation of the completion of the fitting of the male connector A and for a claw opening operation. A space is formed in the back so that the spring piece 35 can bend toward the back.

When the contact cover 26B is at the contact-closing position, the spring piece 35 having the above-mentioned configuration is such that the locking projection 36a on the rear side is locked by the locking claw 35a as shown by the solid line in FIG.
, And the contact cover 26B is kept open. Next, the fitting rib 25 of the male connector A is fitted and inserted into the guide groove 30 so that the protrusion 35b at the center of the spring piece 35 is The spring pieces 35 are pushed in the direction to open each other at the tips, and the locking claws 35a at the tips are
