Field of the Invention The present invention relates to a connector terminal inspector, and more particularly, to a connector attached to an end of a wire harness formed by bundling a plurality of electric wires, the connector being fixed to and housed at one end of the plurality of electric wires. The present invention relates to a connector terminal inspector used to inspect the continuity and insertion posture of a wire terminal.

[0002]

2. Description of the Related Art Conventionally, as this type of inspection device, for example, a configuration as shown in FIG. 5 described in Japanese Patent Application Laid-Open No. 6-123753 is known. In the figure, an inspection portion 2 is provided in a groove-shaped underframe 1 having a U-shaped cross section at an intermediate position so as to be movable in the groove in that direction, and a connector C to be inspected is provided at one end thereof. A connector holding portion 3 for holding the connector at a predetermined position is fixedly provided. The connector C is held in the connector holding unit 3 so that the connector mounting surface side of the connector C on which the mating connector is mounted faces the inspection unit 2 side. The inspection unit 2 has an inspection probe 22 protruding from the front surface facing the connector C held by the connector holding unit 3.

[0003] Although not described in detail, the connector holding portion 3 is shaped so that when the connector C is mounted and stored in the connector holding portion 3 from above, the connector C can be accurately positioned without play. , Is formed in the structure.
In the connector C mounted and housed in the connector holding section 3, a plurality of wire terminals (not shown) whose wire ends are electromechanically connected are housed, and the connector holding section 3 is a wire extending from each wire terminal. The wire harness W / H, which is a bundle of electric wires, is drawn out to the outside.

On the other hand, an operation lever 41 for moving the inspection unit 2 in the groove of the underframe 1 is provided at the other end of the underframe 1, and the operation lever 41 is connected to a link attached to the action point thereof. The operation unit 4 is connected to the rear surface of the inspection unit 2 via an operation lever 42 and includes an operation lever 41 and a link 42.
By pushing the operating lever 41 forward and standing up, a pushing force and a pulling force are applied to the inspection unit 1, and the inspection unit 2 can be reciprocated on the underframe 1.

[0005] In addition, as shown in FIG.
On the front side thereof, there is a concave portion 22 into which the connector mounting surface side of the connector C slightly fits, and a through hole extending in the moving direction of the inspection section 2 is formed in the bottom wall of the concave portion 22 so that the inspection probe 22
Is inserted, and the inspection probe 2 is inserted into the through hole.
The second head projects into the recess 23. The inspection probe 22 is connected to the connector C mounted on the connector holding unit 3.
Are arranged in a number corresponding to the positions of the plurality of electric wire terminals C1 housed therein.

Although not shown, the inspection probe 22 is urged in the connector direction, and is divided into a front probe and a rear probe at a middle portion by a predetermined interval. When it comes into contact with the wire terminal in C and retreats, the front probe and the rear probe, which are divided into two, come into contact with each other.

Therefore, the wire terminal C1 of the connector C
Is connected to the inspection circuit unit 5 via the connector C connected to the other end of the wire harness W / H where the connector C is connected to one end, and the rear probe is directly connected to the inspection circuit unit. As a result, the closed circuit formed by the contact between the front probe and the rear probe as described above is connected to the test circuit unit, and the current flowing through this closed circuit is detected by the test circuit unit. Performs a continuity test. When the current detection is not performed for the wire terminal where the closed circuit is to be formed, the wire terminal C1 is not mounted, and the wire terminal C1 contacts the front probe because the mounting posture is inappropriate. It is predicted that the connection has not been made or that the wire corresponding to the wire terminal has a break.

[0008]

However, some of the connectors include an optional wire used only when it is necessary to operate optional devices or optional functions as wires connected to the housed wire terminals. Some have electric wire terminals. In those having such an optional wire terminal, the wires connected thereto are cut off midway without reaching the connector at the other end of the wire harness W / H, and bundled so that they can be pulled out when necessary. It is in a state of being wound around the outer circumference of another electric wire.

As described above, since the optional electric wire has an open circuit, as described above, the front probe and the rear probe come into contact with each other, so that the wire harness W / H
Depending on whether or not a closed circuit was formed through the electric wire, it was not possible to inspect that the optional electric wire terminal was correctly mounted and accommodated in the connector C.

Therefore, one end of the inspection wire is inserted from the wire terminal insertion port side of the wire on the side opposite to the side where the connector is mounted, and is brought into contact with the wire terminal to which the optional wire is connected. By connecting the other end of the electric wire to the inspection circuit and conducting a continuity test in the same way as other electric wire terminals, it is possible to inspect whether the optional electric wire terminal is inserted into the connector in the correct posture I have to.

[0011] However, such an inspection involves very troublesome work for inserting the inspection wire into the terminal insertion port and maintaining the contact state of the inspection wire with the wire terminal. However, there is a problem that the method cannot be applied to a device in which the terminal insertion port is closed as described above.

In view of the above-mentioned conventional problems, the present invention provides a connector having an electric wire terminal to which an optional electric wire which is drawn out and cut off to form an open circuit is connected. It is an object of the present invention to provide a connector terminal inspector which can easily inspect whether or not a wire terminal is correctly mounted and accommodated.

In the case of this printed circuit board 23a3,
Since a21 and wiring patterns 23a32 are provided in a number corresponding to the wire terminals of the connector C, output pins (23a33 in FIG. 1) are connected to the wiring patterns 23a32 corresponding to the wire terminals to which the cut wires are connected. With this arrangement, it is possible to cope with the case where the wire of any wire terminal is cut off by one type of printed circuit board 23a3. The eight wiring patterns 23a32
Are formed using both sides of the substrate in consideration of the layout.

In the terminal inspection device having the above configuration, FIG.
As shown in (2), after a connector (not shown) is mounted from above the connector holding section 3, a force is applied to the connector holding section 3 by operating operating means (not shown) to operate in the direction of the inspection section 2. As shown in FIG. 4, the connector mounting surface side of the connector held by the connector holding unit 3 is fitted into the recess 25 a of the guide member 25 of the inspection unit 2. When the connector C has the wire terminal C1 in a normal insertion posture, the front conductive pin 22a1 of the inspection probe 22 interferes with the wire terminal C1, so that it retreats against the bias of the coil spring 22a14.

Coil interference 22a14
Of the rear conductive pin 22
Since there is no contact with the tip of b1, conduction is disabled and defective products are confirmed. Therefore, the connector terminal inspector described above uses the one in which the number of the inspection probes 22 corresponding to the number of the wire terminals of the connector is supported by the support block 23 in correspondence with the position of the wire terminal of the connector. A continuity test of the electric wire connected to the device can also be performed.

Never be. Therefore, when inspecting this type of wire terminal C1 for a missing or defective orientation, the wire connected to the output pin 23a33 and the wire connected to the rear conductive pin 22b1 are connected. 23
a3 wiring pattern 23a32, coil spring 22
By checking whether or not a circuit passing through a14 is formed to achieve electrical conduction, it is possible to inspect the wire terminal C1 to which the option wire is connected for a missing or poor posture.

In the above-described embodiment, when the front probe 22a and the rear probe 22b come into contact with each other, the front conductive pins constituting the front probe are provided as means for electrically connecting to the rear probe via the front probe. Although the energizing coil spring and the wiring pattern of the printed circuit board that is in constant contact with it are used, other configurations are possible without being limited to this. For example, a brush that constantly contacts the front probe may be drawn out. However, in the configuration using a coil spring for urging the front conductive pin and the wiring pattern of the printed circuit board which is always in contact, the wiring pattern of the printed circuit board is selected for those having the same arrangement of the wire terminals. Since it is possible to cope with the problem, the versatility is high that it can be used for testing a larger number of connectors, and the configuration is effective in simplifying the configuration and increasing the degree of integration.
