[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION This invention relates to a connector such as a connector for electric wiring (connector plug) of an automobile, particularly a state in which a tip of a cylindrical casing does not project outward to an end supporting portion provided inside thereof. The present invention relates to an improvement of a jig used for connecting a connector to a continuity inspection circuit (continuity inspection device) when performing a continuity inspection on a connector having a terminal lock member inserted and attached.

2. Description of the Related Art As jigs of this type, there are a connector support base fixedly mounted on a base frame for immovably supporting a connector to be subjected to a continuity test, and a pivot pin provided on the base frame at a distance from the connector support base. Between the connector support base of the base frame and the operation lever, which is swingable so as to approach and separate from the connector support base supported by the connector support base A terminal block having a connector mating recess with a terminal in the connector support base facing portion, which is installed so as to be able to be pushed to, and a spring which is engaged with the terminal block and urges the terminal block to abut the operating lever. The one provided is commonly used.

In this conventional jig, a connector to be inspected for continuity is supported laterally on a connector support base so that a tip portion (substantially the first half portion) including a tip portion thereof projects toward the terminal block side. In this state, by swinging the operating lever toward the terminal block, the terminal block is pushed toward the connector support base against the force of the spring, and finally the connector mating recess of the terminal block Mate it to the front,
After checking the conduction state by contacting the terminal of the connector with the terminal attached to the terminal block, release the swing of the operating lever to separate the terminal block from the connector support base with the acting force of the spring. Then, the engagement between the connector engaging recess of the terminal block and the connector is released, and at the same time, the operation lever is swung to the side opposite to the terminal block for use in the next continuity test.

[0004]

However, in the above-mentioned conventional jig, the terminal lock member inserted in the terminal hooking portion of the casing has an incomplete terminal hooking in the terminal hooking portion. If the insertion block is stopped (blocked) in the middle of the connection, when the terminal block is engaged with the connector by swinging the operation lever, the operation lever pushes the terminal block strongly. Since the terminal lock member is pushed forcibly against the insertion restraint state, there is a problem that the terminal lock member and the terminal hooking portion of the casing are damaged (damaged). In addition, despite such damage to the connector components, the terminals of the connector and the terminals of the terminal block may come into contact with each other and become conductive. Therefore, if this damage is overlooked, it is mistaken for a good product. There is also the problem of doing.

Therefore, according to the present invention, when the terminal flock member is incompletely attached to the casing as described above, complete mating of the connector mating recess of the terminal block with the connector is prevented. By doing
The purpose is to prevent damage to the connector terminal lock member and the like.

[0006]

According to the present invention, according to the present invention, the pivot pin of the operating lever can be moved toward and away from the terminal block on the base frame in the jig having the conventional structure as described above. This is achieved by engaging the pivot pin with a spring that urges the pivot pin toward the terminal block side with a force that substantially opposes the action force of the terminal block biasing spring.

[0007]

In the jig of the present invention, in the case of a connector in which the terminal lock member is not completely inserted into the casing, when the terminal block is pushed by the swinging of the operation lever, it is attempted to engage with the connector. , When the connector mating recess of the terminal block abuts the tip of the terminal lock member in the insertion restrained state and tries to push the terminal lock member, this pushing force is applied to the action force of the terminal block biasing spring. The corresponding reaction force is added, and the reaction force that exceeds the action force of the biasing spring of the pivot pin of the operation lever as a whole,
As a result of acting on the pivot pin via the terminal block and the operating lever, the biasing spring of the pivot pin is compressed and the pivot pin, and thus the lower end of the operating lever, moves to the side opposite to the terminal block.
That is, the pressing force against the tip of the terminal lock member of the terminal block, which is induced through the swing of the operation lever, causes the compression of the pivot pin biasing spring of the operation lever, and thus the pivot pin (pivotally attached portion) of the operation lever. It is absorbed by the movement to the opposite terminal block side, the terminal block does not move to the connector support side, and the terminal lock member receives no pushing force. Therefore, the connector mating recess of the terminal block is not completely mated with the connector, and the terminal of the connector mating recess does not come into contact with the terminal of the connector.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT The drawings illustrate a preferred embodiment of the jig of this invention. The jig shown in the drawing moves the connector 30 forward and in the width direction of the base frame 11 into the groove of the front end portion of the groove-shaped base frame 11 including the bottom plate (bottom wall) 12 and the pair of side plates (side walls) 13. The connector support base 14 that supports the terminal 1 is fixed in the groove of the central portion of the base frame 11 on the front side thereof.
7 with connector mating recess 16 and terminal 1 on the rear side
The terminal block 15 having the lead wire 18 for connecting 7 to the continuity checker is slidably engaged with the bottom plate 12, the side plates 13 and the guide 19 attached to the lower portions of the side plates so as to extend in the front-rear direction, and the groove is formed. The terminal block 15 of the bar 20 is mounted so as to be movable back and forth inside, and penetrates the lower portion of the terminal block 15 on the bottom plate 12 of the base frame 11 and extends back and forth.
The coil spring 21 for urging the terminal block 15 toward the rear side opposite to the connector support base is wound between the connector support base 14 and the connector support base 14, and further, in the vertical center of the rear part of the side plates 13 of the base frame 11, A pivot pin support member 22 having a pin insertion hole 23 extending in the front-rear direction is fixed so that the pin insertion hole 23 communicates with the inside and outside of the side plate 13, and is slid into the pin insertion hole 23 of the pivot pin support member 22. The lower end of a bifurcated operating lever 25 having a triangular cam-shaped pressing portion 26 at the lower part is pivotally attached via a pivot pin 24 freely inserted, and the inside of the upper rear end of the side plates 13 A lever stopper 27 for restricting the rearward swing of the operating lever 25 is attached to the pivot pin support member 22, and the pivot pin 2 is attached to the pivot pin support member 22 in a steady state (in the most extended state).
4 is provided on the terminal block side, and a coil spring 28 for urging the terminal block 15 by an acting force that opposes the maximum acting force of the coil spring 20 that urges the terminal block 15 rearward is provided.

The jig of this illustrated example has a terminal lock member 32.
In the case of the connector 30 which is completely inserted into the casing 31 as indicated by the chain double-dashed line, the operation lever 25 has its pivot pin 24 substantially the pin insertion hole 23 of the pivot pin support member 22 from beginning to end. When the terminal block 15 is swung in the state of being located at the front end of the connector block, the front end face portion around the connector fitting recess 16 abuts the rear end face part of the connector support base 14, and the connector fitting recess 16 of the connector 30. It can be pushed until it is completely engaged with the first half portion protruding from the connector support base 14.

On the other hand, the terminal lock member 32 is the casing 31.
If the connector fitting recess 16 of the terminal block 15 hits the tip of the terminal lock member 32 when it is not completely inserted into the casing and protrudes from the tip of the casing 31, the tip of the terminal lock member 32 is newly added. The reaction force of the pressing force acts on the pivot pin urging coil spring 28 via the terminal block 15, the operating lever 25 and the pivot pin 24.
Via compression of the pivot pin 24 and thus the operating lever 25
The lower end portion of moves to the rear and absorbs this reaction force.
As a result, even when the operation lever 25 is swung to the front side of the terminal block 15 to the limit of its swing, the terminal block 15 does not advance to the connector support side at all, and the terminal lock member 32 of the connector 30 is not pushed. At the same time, the terminal 17 of the connector engaging recess 16 of the terminal block 15 is connected to the connector 3
It does not touch the 0 terminal.

[0011]

As is apparent from the above, according to the jig of the present invention, in the case of a connector in which the terminal lock member is not completely inserted, the connector mating recess of the terminal block has the tip of the terminal lock member. After the contact with the terminal block, the pivot part of the operating lever only moves to the side opposite to the terminal block.
Therefore, since the terminal lock member is not pushed at all,
There is no risk of damage to the terminal lock member or the terminal hooking part of the casing, and because the connector mating recess of the terminal block and the connector do not mate completely, the two terminals do not touch and there is always a non-conducting abnormal connector. Detected as.
