BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness inspection device for inspecting continuity of a wire harness.

[0002]

2. Description of the Related Art FIGS. 5 (a) and 5 (b) show a wire harness inspection device (hereinafter referred to as "inspection device") 1 of this type. In the figure, the inspection apparatus 1 includes an inspection table 8 in which an inspection plate 7 is fixed on four legs 5 standing on the floor 3.
And a plurality of connector terminal inspection tools 9 fixed on the inspection plate portion 7 of the inspection table 8 and a display device (not shown) connected to the connector terminal inspection tools 9 and displaying the continuity inspection result of the wire harness. ..

The connector inspection tool 9 is a so-called toggle clamp type inspection tool, and as shown in FIG. 5 (b), side walls 11 and 11 (however, only one side is shown in FIG. 5 (b)).
A connector receiving portion 15 is formed at one end of a U-shaped base 13 having a lever, and a lever 17 is rotatably supported on both side walls of the other end. A continuity inspection unit 19 is movably arranged in the middle of the base 13. The continuity inspection unit 19 and the lever 17 are connected by a link 21, and the continuity inspection unit 1 is rotated by the rotation of the lever 17.
9 is adapted to come into contact with and separate from the connector receiving portion 15.

The continuity inspection section 19 is a connector A to be inspected.
A recess 23 into which the tip of FIG. 5A is fitted is formed, and in this recess 23, a detector (continuity inspection pin) that comes into contact with a terminal fitting (not shown) housed in the connector A is formed. ) Are provided in a protruding manner by the number of terminal fittings of the connector A. The detector is connected to a control device (not shown).

The connector receiving portion 15 is the inspection portion 1 described above.
9 and a connector insertion portion 25 formed with a fitting recess into which the connector A to be inspected is fitted, and a support plate 27 that supports the connector insertion portion 25 (Japanese Patent Laid-Open No. Sho 60).
-140160 publication).

In order to inspect the continuity of the wire harness W and the connector A by the inspection device 1 as described above, the connector A connected to the tip of the wire harness W is placed in the connector receiving portion 15 of the connector terminal inspection tool 9. Insert each. Next, the lever 17 of the connector terminal inspection tool 9 is rotated to bring the continuity inspection section 19 close to the connector A, and the detector is brought into contact with the terminal fitting of the connector A to inspect continuity.

The electric wires 57 are connected to the rear ends of the terminals 1 and 51 via terminal fittings 59 and connected to the control device 87.

The continuity inspection pin 51 is shown in FIG.
As shown in (b), after being inserted through the compression coil spring 55 arranged in the through hole 47 of the detector body 35, it projects to the back side of the detector body 35, and the projected rear end portion is Terminal fitting 59 crimped to the end of the electric wire 57
Is fitted to. A pin stopper 61 is formed on the continuity inspection pin 51 in the through hole 47 on the connector insertion portion 43 side along the axis-perpendicular direction, and the pin stopper 61 and the spring fixed to the rear end side of the through hole 47. The compression coil spring 55 is arranged between the stopper 65 and the stopper 65. As a result, the continuity check pin 51 is biased toward the connector insertion portion 43 side by the compression coil spring 55. A peripheral wall 53 is formed around the continuity inspection pins 51, 51.
It is designed to be inserted between a connector housing (not shown) of the connector A and a cover portion.

The support lever 37 of the connector is shown in FIG.
As shown in (a) and (b), a lever support plate 67 fixed to the support plate portion 41 is rotatably supported by a rotary shaft 71, and one end portion is formed in the detector body 35. It penetrates through the recess 68 and projects toward the connector insertion portion 43 side. The other end of the drive shaft 7 of the solenoid 39 passes through a rectangular through hole 69 formed in the support plate 41.
3 is rotatably connected.

One end of the support lever 37 of the connector on the connector insertion portion 43 side is bent at a substantially right angle toward the connector insertion portion 43 side and is attached to the back portion 75 of the connector A inserted into the connector insertion portion 43. An engaging portion 77 that engages is formed. The solenoid-side end 79 is rotatably connected by a pin 85 to a drive shaft 73 that is pulled into the solenoid main body 81 when energized, and projects from the solenoid main body 81 by the biasing force of the compression coil spring 83 when not energized. ing.

The solenoid 39 is the solenoid body 8
1 and the drive shaft 7 inserted in the solenoid body 81
3, the solenoid body 81 is fixed to the support plate portion 41.

This solenoid 39 is
2A, the back portion 75 of the connector A inserted into the connector insertion portion 43 engages with the engagement portion 77 of the support lever 37, and the connector insertion portion 43 supports the connector A. However, once the connector is engaged, it is difficult to release it by the compression coil spring 83, but it is preferable to adjust the compression coil spring 83 to a force that can be easily released with a finger. Then, in the energized state, the support lever 37 resists the urging force of the compression coil spring 83 and rotates clockwise around the rotation shaft 71 (direction of arrow a in the figure).
2 to the connector insertion portion 4 as shown in FIG.
The engagement state of the engagement portion 77 with the back portion 75 of the connector A inserted into the connector 3 is released.

Further, in this state, the detection parts 49 of the continuity inspection pins 51, 51 of the continuity inspection part 45 come into contact with the terminal fittings accommodated in the terminal accommodating chamber of the connector A.

Next, when the switch is turned on in step S2, the continuity inspection section 45 inspects the continuity of the connector A and the wire harness W in step S3. The result of this continuity test is determined in step S4. If the continuity of all the connectors and wire harnesses is normal, the notifying means 91 is activated to notify that the continuity is normal, and the solenoid 39 is driven in step S5 to connect the back portions 75 of the plurality of connectors A to each other. The engagement of the support levers 37 is released at the same time. When the support lever 37 is disengaged from the back portion 75 of the connector A, the connector A is pushed outward from the connector insertion portion 43 by the biasing force of the compression coil spring 83.

Then, in step S6, it is determined whether or not to continue the inspection, and if it is not continued, the continuity inspection ends. To continue the continuity check, step S1
The following is executed again. If there is a conduction failure in the connector in step S4, the notification means 9 is sent in step S7.
1 is activated to notify the operator that there is a poor continuity of the connector.

Although the solenoid 39 is used as a means for driving the support lever 37 in the above embodiment, the support lever 37 may be manually driven.

Further, in the above embodiment, the example in which the compression coil spring 55 as the urging means is provided in the continuity inspection pin 51 has been shown, but the means for urging the connector A may be another portion or another structure. ..

Further, in the above embodiment, an example in which a solenoid is used as the driving means has been shown, but the present invention is not limited to this, and other means may be used.

Further, in the above embodiment, the support lever 37 was driven via the solenoid 39 as the driving means, but the driving means may be directly provided with the engaging portion of the connector.

Further, in the above embodiment, the support lever 37 is engaged with the back portion 75 of the connector A, but the back portion of the connector A may have another shape such as a concave portion, a convex portion or a groove portion formed in the connector A. ..
