[Prior art]

 In wire harnesses used for wiring electrical components in automobiles, connectors are used to connect the wire harnesses to each other and to connect the wiring harness to electrical components. This connector generally has a housing made of a synthetic resin material and a terminal fitting attached to the housing. The housing includes a female housing and a male housing that can be combined with each other, and a female terminal fitting and a male terminal fitting that can also be connected to the terminal fittings. Then, for example, a female terminal fitting is attached to the female housing to be called a female connector, and a male terminal fitting is attached to the male housing to be called a male connector. When the female connector and the male connector are connected to each other, the male and female housings are fitted together, and the male and female terminal fittings to be interconnected are coupled to each other to achieve the electrical connection.

By the way, there are cases where the terminal fitting is forgotten to be attached to the housing, or the terminal fitting is not inserted to the correct mounting position. In such a case, a malfunction occurs in the electric components of the automobile. Therefore, at the final stage of wire harness production, it is necessary to thoroughly inspect whether the terminal fittings are correctly and securely attached to the housing.

Therefore, conventionally, in order to inspect the mounting state of the terminal fittings, various connector continuity inspection devices for conducting a continuity test of the connector have been proposed. FIG. 6 is a diagram showing a simplified configuration of a conventional connector continuity inspection device. Referring to FIG. 1, the conventional connector continuity inspection device includes a base 1. The base 1 is fixed on an inspection drawing board (not shown) on which a wire harness assembled by bundling a plurality of covered electric wires is placed. On the base 1, there are provided a connector receiving portion 3 for holding the connector 2 to be inspected and an inspection portion 4 facing the connector receiving portion 3. The connector receiving portion 3 is fixed to one end of the base 1, and the inspection portion 4 is slidably attached to the base 1. The inspection unit 4 is provided with a plurality of detectors (not shown) provided corresponding to the plurality of terminal fittings mounted on the connector 2 to be inspected. Further, a lever mounting piece 11 is erected at the end of the base 1 opposite to the connector receiving portion 3. A lever 7 is rotatably attached to the lever attachment piece 11 around the horizontal axis 5. A cam portion 71 protruding toward the inspection portion 4 is integrally formed on the lever 7. The cam portion 71 is in contact with the back surface of the inspection unit 4.

In conducting the continuity inspection, the connector 2 to be inspected is attached to the connector receiving portion 3, and the lever 7 is rotated in the A direction shown in FIG. 6A. With the operation of the lever 7, the cam portion 71 presses the inspection portion 4, and the inspection portion 4 slides toward the connector receiving portion 3. As a result, as shown in FIG. 6B, the terminal fitting (not shown) of the connector 2 and the detector (not shown) of the inspection unit 4 come into contact with each other. As a result, conduction between the terminal fitting and the detector is obtained.

[0006]

[Problems to be solved by the device]

 By the way, recently, in order to meet the needs of consumers, automobiles are provided with different types of optional functions corresponding to grades, for example. As a result, the number of electrical components used has increased, and the branching shape of the wire harness has become more complicated. As a result, electric wires are gathered from multiple directions at a specific part of the wire harness, such as a fuse box. As a result, the wires are not connected in the correct positions and wiring mistakes occur, or the space for installing a fuse box etc. is wide.

In order to deal with such a situation, a so-called composite connector in which a plurality of sub connectors are combined with a main connector is used in a fuse box or the like where many electric wires are concentrated. In other words, this composite connector is configured so that the connection port of the main connector and the connection port of each sub-connector intersect with each other and that the wires with the same pull-out direction can be arranged and connected. Therefore, it is possible to prevent incorrect wiring and to effectively use the limited space of a car.

However, in the conventional connector continuity inspecting apparatus as shown in FIG. 6, the inspecting unit 4 having the detector for detecting the quality of conduction can be slid only in one direction. Therefore, in order to conduct a continuity test of a composite connector having connection ports in more than two directions, the main connector and sub-connector must be separately conducted before they are combined. I have to do it. When conducting a continuity test after combining the main connector and sub-connector, it is necessary to have the same number of continuity test devices as the number of connectors with different opening directions of the connection ports. A continuity check must be performed. That is, in any of the above cases, the same work had to be repeated several times without ending one conduction test. As a result, the continuity check takes time and effort. Moreover, the repetition of the continuity test induces the forgetting of the test. As a result, it is easy to forget to attach the terminal fittings of the connector.

The present invention has been made in view of the above technical background, and an object thereof is to provide a connector continuity inspection device capable of performing a continuity inspection of a composite connector having connection ports in two or more directions at one time.

[0010]

[Means for Solving the Problems]

A main inspection means that is compatible with each of the terminal fittings, and that includes a plurality of detectors protruding toward the connection port of the main connector, and a composite connector held by the connector receiving means. Among them, it is arranged facing the connection port of the sub connector, corresponds to each terminal fitting of the sub connector to be inspected, and includes multiple detectors protruding toward the connection port of the sub connector. Sub-inspection means, operation means for bringing the main inspection means close to a predetermined position with respect to the connection port of the main connector held by the connector receiving means, and separating the main inspection means from the adjacent position to the original position, and the above-mentioned operation. When the main inspection means is brought close to the connection port of the main connector by the means, the sub-inspection means is brought close to a predetermined position with respect to the connection port of the sub-connector along a direction intersecting the moving direction of the main inspection means. When the main inspection means is separated from the connection port of the main connector by the operation means, the auxiliary inspection means is moved from the proximity position to the original position along a direction intersecting the moving direction of the main inspection means. Those which comprise interlocking means for.

[0011]

[Action]

 In the above problem solving means, there is provided interlocking means for interlocking with the movement of the main inspection means by the operating means so as to bring the sub-inspection means into and out of contact with the connection port of the sub-connector held by the connector receiving means. ing. Therefore, when the main inspection means is brought close to the connection port of the main connector by the operating means, the sub-inspection means can be brought close to a predetermined position with respect to the connection port of the sub-connector by interlocking with this. On the other hand, when the main inspection means is moved away from the connection port of the main connector by the operating means, the sub-inspection means can be moved away from the proximity position to the original position in conjunction with this.

As described above, by simply operating the operating means, it is possible to inspect the mounting states of the terminal fittings of the main connector and the sub connector in which the connection ports intersect each other at once.

Next, when the lever is rotated in the X4 direction, the main inspection unit 80 is pressed by the cam portions 103 and 104 of the lever, and the main inspection unit 80 moves along the main slide rails 501 and 502. Slide forward (X2 direction). Along with this, the taper surface 111a of the pressing arm 111 contacts the sliding roller 112. From this state, when the lever is further rotated in the X4 direction and the rotation is completed until the lever stands substantially vertically, the state shown in FIG. 5 is obtained. That is, from the state shown in FIG. 3, if the rotation operation of the lever is continued, the main inspection unit 80 is slid further forward. At this time, the sliding roller 112 rolls along the tapered surface 111a of the pressing arm 111, and as a result, the sub-inspection unit 90 moves forward along the sub-slide rails 601 and 602 (Y2 direction) against the biasing force of the coil spring. Slide into and fit into the bent portion of the pressing arm 111. Further, when the lever is rotated to a position where it stands in a substantially vertical position, the main inspection unit 80 slides to the most front position and comes close to a predetermined position with respect to the connection units 201 to 203 of the main connector C1. . Following this, the sub-inspection unit 90 also slides to the frontmost position and approaches the predetermined positions with respect to the connection ports 401 to 403 of the sub-connectors C21 to C23. As a result, the terminal fittings T11 to T13 installed in the main connector C1 and the detectors 803a and 804a of the main inspection unit 80, and the terminal fittings T21 to T23 and the sub inspection unit installed in the sub connectors C21 to C23. The 90 detectors 905a to 907a abut. As a result, the terminal fittings T11 to T13 installed in the main connector C1 and the detectors 803a and 804a of the main inspection unit 80, and the terminal fittings T21 to T23 installed in the sub connectors C21 to C23 and the sub inspection unit 90. Conduction with the detectors 905a to 907a is obtained.

As described above, by simply operating the levers, the mounting states of the terminal fittings T11 to T13 and T21 to T13 mounted in the main connector housing C1 and the sub-connectors C21 to C23 that are combined in a state of being orthogonal to each other. (Continuity test) can be done at once. Therefore, the continuity inspection can be performed once without repeating the same work. As a result, the continuity inspection does not take time and effort. Also, since the inspection only needs to be done once, it is possible to avoid forgetting the inspection which is likely to occur by repeating the inspection many times. Therefore, it is less likely to forget to attach the terminal metal fittings, which may lead to malfunction of the electric components of the automobile.

It should be noted that the present invention is not limited to the above embodiment, and many modifications and changes can be made within the scope of the present invention. In the above-mentioned embodiment, the inspection unit provided with the detector is provided at two places, and the configuration is described in which the inspection unit is moved toward and away from the two directions intersecting each other with respect to the composite connector. It is also possible to provide three or more inspection parts and to make the inspection parts approach and separate from the composite connector in three or more directions intersecting each other.

Further, if the interlocking mechanism for interlocking the main inspection unit and the sub inspection unit is devised, the sub slide rail is set to the upright state, and the main inspection unit is moved horizontally toward and away from the composite connector. If the sub-inspection unit is configured to approach and separate in the vertical direction, it is possible to perform a three-dimensional continuity inspection.

[Effect of device]

 As is apparent from the above description, according to the present invention, it is possible to simultaneously inspect the mounting states of the terminal fittings of the main connector and the sub-connector whose connecting ports intersect each other by operating the operating means. it can. Therefore, it is not necessary to repeat the same work, and the continuity test of the composite connector can be done only once. As a result, there are excellent effects that the continuity inspection does not take time and labor, and that forgetting to attach the terminal metal fittings that may cause malfunction of the electric components of the vehicle does not easily occur.
