Problems solved by technology

[0006] However, in the method of the above-mentioned Patent Document 1, the inspection must be carried out after the inspection probe is directly brought into contact with the terminals of both the inspection signal supply side and the inspection signal receiving side of the inspection signal harness by the inspection device. Inspect the shape of the connector of the cut crimped wire terminal of the wire harness to make it. Every time a dedicated inspection probe must be reliably in contact with at least a part of the terminal mounted on the connector
[0007] In addition, terminal deformation may occur due to aging, wear, or damage of inspection probes
[0008] Also, as connectors become smaller and denser, the cost of making jigs that match the connectors also increases

[0027] First refer to figure 1 The principle of checking the mounting state of terminals to which the device for confirming the mounting state of terminals of the present invention is applied will be described. figure 1 It is a schematic diagram for explaining the basic principle of the terminal mounting state confirmation device for detecting the mounting state of the crimping electric wire terminal to the connector according to the first embodiment of the present invention.

[0028] exist figure 1 Among them, 10 is a connector shell (hereinafter referred to as "connector") constituting the end of the wire bundle to be inspected. At a predetermined position in the connector 10, one end of a predetermined specification cut and crimped wire 300 is Insert the terminal to the specified depth.

[0029] The cut and crimped electric wire 300 attached to this connector is cut to a predetermined length in advance, and a terminal of a predetermined specification to be attached to the...

[0110]In the above description, an example in which a storage space for accommodating a connector is provided approximately in the center of the accessory part has been described. However, the present invention is not limited to the above examples. For example, one accessory part may have two or more accommodation spaces for accommodating two or more connectors. Alternatively, two or more accessory parts may be accommodated in the connector housing part of the connector holding part, and a connector may be accommodated in each accessory part. With the above configuration, it is possible to check the state where the terminals are inserted into two or more connectors.

[0111] A second embodiment of the present invention in which a plurality of connectors are accommodated in the connector accommodating portion of the connector holding portion will be described with reference to FIG. 6 . Fig. 6 is a diagram for explaining accessory parts of a second embodiment of the present inv...

[0119] In addition, in the embodiments described above, an example in which the X-axis or Y-axis sensor boards are arranged opposite to each other with the connector housings interposed therebetween has been described. However, the present invention is not limited to the above example, and the two sensor boards may be positioned on one side of the connector housing portion with a certain distance apart and approached approximately in parallel.

[0120] For example, by attaching sensor boards to both sides of a thin-plate-shaped insulating material and placing them on the inner wall surface of one side of the connector housing, the two sensor boards are separated by a certain distance on one side of the connector housing. It is sufficient to position and set approximately parallel.

[0121] In addition, the arrangement method of the sensor board is not limited to the above example, and may be embedded in the side wall, or attached to the side wall of the attachment part when us...

Abstract

An inspection jig for a harness inspection device, where, even when specifications of a connector constituting harness are changed, it can be dealt with by a small change, eliminating need for newly making all jigs, as has been conventionally done, every time when connector specifications are changed. A connector-holding section (400) having a receiving section (450) for receiving a connector housing (10), wherein sensor plates are provided on side inner wall sections, which are opposite to each other, of the receiving section (450), an alternate current signal is applied to a terminal inserted in a connector (10), the alternate current signal from the terminal is detected by the opposite sensor plates, the relative distance between the sensor plates and the terminal is detected by an inspection control section (100) based on the signal detected by the opposite sensor plates, the position of the terminal installed in the connector is detected from a relative value of the detection signal at the sensor plates, and thus whether or not the terminal is correctly inserted is confirmed. When the outer size of the connector is smaller than the connector-receiving section (450), the connector (10) is set in a through-hole (465a,b) of an attachment member (460a, 460b), and the connector (10) is received in the connector-receiving section (450) together with the attachment member (460a,b).

Description

technical field [0001] The present invention relates to a mounting inspection jig capable of inspecting the installation of crimped electric wires with fixed terminals in connectors, even with various types of connector housings, by replacing only a part of the jig. Background technique [0002] When manufacturing a wire harness, it is necessary to confirm whether the wire harness is assembled correctly. Conventionally, for example, in Patent Document 1, each input terminal of the input terminal group on the main body side of the inspection device and each connection terminal of each output terminal of the output terminal group are connected to the input-side connector and the output-side connector on the work panel side, respectively. On the device, in the operation of the storage mode before the inspection, insert the connectors at both ends of the model wire harness on the input side and output side connectors on the work panel side, and connect the terminals and connecto...
