Related to inspection jigs.

[0002]

2. Description of the Related Art As a conventional continuity inspection jig for a connector of this type, there is, for example, one shown in FIGS.
In FIG. 4, reference numerals 1 and 2 denote split jigs. These split jigs 1 and 2 can be approached or separated by an actuator such as an air cylinder or a hydraulic cylinder (not shown). A plurality of contacts 1a, 2a are provided in parallel on the opposing surfaces of the split jigs 1, 2, and the contacts 1a, 2a are connected to a conduction device via lead wires (not shown).

[0005] On the other hand, in FIG. 5, reference numeral 3 denotes a connector main body, and a connector terminal 4 is provided inside the connector main body 3, and the connector terminal 4 has a terminal 6 a of an electric wire 6 constituting a wire harness 5. Are connected. The connector body 3 has a plurality of openings 3a.
The opening 3a communicates with the connector terminal 4, and the contacts 1a and 2a can contact the terminal 6a through the opening 3a.

In the continuity inspection device having such a configuration, after the terminal 6 is connected to the connector terminal 4, FIG.
As shown in FIG. 4A, the connector main body 3 is set between the dividing jigs 1 and 2, and then the actuator is driven by an operation unit (not shown) to bring the dividing jigs 1 and 2 close to each other. The contacts 1a and 2a are brought into contact with the terminals 6 through the openings 3a as shown in b).

Next, by conducting the terminal 6a from the contacts 1a, 2a, it is checked whether or not the electric wire 6 is connected to the connector terminal 4 without being broken.

[0006] Thereafter, the actuator is driven by the operation unit to separate the jigs 1 and 2 and the connector body 3 is removed.

[0007]

However, in such a conventional continuity inspection apparatus, an operation of moving the split jigs 1 and 2 closer to and away from each other by an actuator is required. However, there is a problem that the workability of the inspection work is deteriorated and the structure of the inspection device is complicated and the cost is increased by the necessity of the actuator.

Accordingly, an object of the present invention is to provide a simple and low-cost connector continuity inspection jig which can improve the operability of the continuity inspection.

[0009]

According to the first aspect of the present invention,
In order to solve the above-mentioned problem, there is provided an inspection jig for inspecting continuity when a connector terminal provided inside a connector main body and a terminal of an electric wire are connected, wherein the connector is passed through an opening formed in the connector main body.

And a biasing member for biasing the contact so as to protrude from an inner peripheral surface of the main body jig.

In this case, when the connector main body is inserted into the main body jig, the contact collides with the connector main body and retracts into the inner peripheral surface of the main body jig against the urging force of the urging member. Furthermore, when the connector body is inserted into the body jig, the contact is located at the opening, so that the contact is urged by the urging member, protrudes from the inner peripheral surface, and is connected to the connector terminal through the opening. In order to make contact with the terminal, the continuity of the wire is inspected by a contact.

When the connector main body is moved from the main body jig in the direction opposite to the insertion direction after the inspection is completed, the contact retracts from the opening into the inner peripheral surface of the main body jig against the urging force of the urging member. The connector body can be removed from the body jig.

As described above, the contact can be easily brought into contact with and separated from the terminal of the electric wire by the operation of inserting / removing the connector main body from / to the main body jig, so that the workability of the continuity test can be improved, and Since the conventional actuator is not required, the configuration of the continuity inspection device can be simplified and the manufacturing cost can be reduced.

According to a second aspect of the present invention, in order to solve the above-mentioned problem, in the first aspect of the present invention, the tip of the contact is curved.

In this case, it is possible to prevent the contact from being caught on the connector body when the connector body is inserted into or removed from the body jig.
