Abstract

PURPOSE:To enable an inspection tool to be moved and workability to be improved and prevent disconnection by mounting a conduction inspection tool on a plate material so that it can move freely through a flexible tube and then allowing a lead wire to be passed through a tube with much room in longer direction. CONSTITUTION:A screw sleeve with flange 12 is inserted into a wire penetration hole 3 which is provided on a plywood 30, it is screwed into one edge of a flexible tube 10 through a washer 11, and then the tube 10 is fixed to the plate 30. Also, a conduction inspection tool 20 which is connected to a branch terminal of a wire harness is fixed to other edge of the tube 10 by screw the rear edge part. A lead wire 21 which is extended from the rear edge part passes through the tube 10 with room in the direction of the length and is connected to a connector 22 at a lower surface side of the plywood 30. Then, conduction inspection is performed by connecting a lead wire from a conduction measuring equipment to this connector 22. Thus, an inspection tool can be moved owing to flexibility and shape-retaining property of the flexible tube and disconnection can be prevented since the wire is protected by the flexible tube.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a conduction plate for continuity testing used in conducting a continuity test of a wire harness, and particularly to a continuity plate that can improve the workability of the continuity test.

[Prior art and problems with the invention]

Continuity testing of a wire harness is performed by connecting a continuity measuring device to each branch terminal, and the connection between the terminal and the continuity measuring device is performed using a continuity testing jig for the lead wire terminal led from the continuity measuring device. be exposed.

By the way, such a continuity test is usually performed on many wire harnesses of the same shape, so as shown in Figure 5, each branch terminal position of the wire harness is tested in consideration of workability and durability. In addition, a conduction plate 50 is used in which a continuity test jig 51 is fixed to a plate material 52 in advance.

However, in the case of a wire harness in which the branch terminals are close to each other or located above and below each other, when the continuity test jig 51 is fixed in place, they will come into contact with each other, so that the branch terminals may be placed in positions that do not match the branch shape of the wire harness. The continuity test jig 51 may need to be fixed. When conducting a continuity test using such a continuity plate 50, the branch terminal of the wire harness may not reach the continuity test jig 51, or the wire harness must be forcibly pulled to connect, making the work very laborious. It's a difficult situation.

In order to prevent this, sufficient consideration must be given to the placement of the continuity test jig 51. However, if it is impossible to mount the continuity test jig 51 in the proper position, as shown in FIG. It is used without being fixed.

Therefore, as shown in FIG. 7, if the continuity test jig 51 is pulled when connecting the wire harness a, tension is directly applied to the lead wire 53 that connects the continuity test jig 51 and the continuity measuring device. This may cause breakage of the lead wire 53, or may cause premature damage to the lead wire due to friction between the lead wire and the plate material.

Therefore, an object of the present invention is to make a continuity testing jig movable and to protect the lead wires.

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention provides the above-mentioned continuity plate in which a continuity test jig is fixed to the plate material in accordance with the branch terminal of the wire harness, in which the continuity test jig is movably connected to the plate material through a flexible tube. The lead wire is attached to the flexible tube, and the lead wire is passed through the flexible tube with a margin in the length direction.

[Effect]

In the conduction plate configured as described above, the continuity test jig is moved three-dimensionally within a certain range and held at that position due to the flexibility and shape retention of the flexible tube, as in the conventional case. . In addition, since the lead wires are passed through the flexible tube with some room in the longitudinal direction, even if the flexible tube is deformed due to the movement of the continuity test jig, tension is immediately applied to the lead wires. Never.

(Example〕 Examples will be described below with reference to the drawings.

As shown in FIG. 2, this continuity plate has another continuity testing jig 20 attached via a flexible tube 10 in a narrow space between continuity testing jigs 20a directly fixed to a plywood board 30.

The mounting structure of the continuity test jig 20 is as shown in FIG. As shown in the figure, the flanged sleeve 12 is inserted into the wiring through hole 31 provided in the plywood board 30, and the threaded sleeve 12 is screwed into one end of the flexible tube 10 through the washer 11. is fixed to a plywood board 30.

A continuity test jig 20 connected to the branch terminal of the wire harness is fixed to the other end of the flexible tube 10 by screwing the rear end, and the lead wire 21 extending from the rear end has an allowance in the length direction. It passes through the flexible tube 10 while holding it, and is connected to the connector 22 on the lower surface side of the plywood board 30.

Therefore, by connecting a lead wire from a continuity measuring device to this connector 22, a continuity test can be performed. Furthermore, as shown in FIG. 3, due to the flexibility and shape retention of the flexible tube 10, the continuity test jig 2 can be freely used within a certain range.
0 can be moved and held.

Therefore, as shown in Figure 4, it is now possible to connect the wire harness in the vertical direction, making it possible to conduct continuity tests that follow the shape of the wire harness without applying excessive load. .

Further, although not shown in the drawings, the continuity testing jig may not be directly fixed to the plate material, but may be entirely fixed to the plate material via a flexible tube. By doing this, the space on the board can be used quite effectively.

〔effect〕

As described above, the continuity plate of the present invention employs a configuration in which the continuity test jig is attached to the plate material via a flexible tube, and the wiring of the continuity test jig is passed through the flexible tube. The conductivity test jig can be moved due to its flexibility and shape retention, and the connection direction with the wire harness can also be arbitrarily specified.

Therefore, even if it is not possible to attach the continuity test jig to the optimal position on the plate material as in the past, there is no need to forcibly pull the wire harness, resulting in good workability. In addition, since the wiring is protected by a flexible tube, no load is applied directly to it, which helps prevent wire breakage. This widens the tolerance range for the layout of the continuity test jig, making it possible to There is no need to waste time on revision work.
