DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for inspecting a connector comprising a connector housing and terminals mounted on the housing.

[0002]

2. Description of the Related Art A connector attached to an end of an electric wire such as a wire harness has a terminal attached to the end of the electric wire and a connector housing to which the terminal is attached. The operation of attaching the connector to the wire harness is performed by inserting a terminal connected to the end of the electric wire into the connector housing in advance. In this operation, it is required that the terminal is properly mounted on the connector housing. Therefore, the connector is inspected using a test jig to check whether the state of the terminal mounted on the connector housing is normal.

[0003]

As described above, the connector connected to the electric wire is inspected by the inspection jig. As a result, the worker who attaches a check mark to the connector judged to be a non-defective product. , Bag in specified quantity. However, since the above-mentioned marking and bagging were performed manually, the marking was forgotten, wrongly attached, and the number of bags packed was excessive or insufficient.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and is an inspection system of a connector for inspecting a mounting state of a terminal mounted on a connector housing. An inspection jig indicated by an electric signal, a marker operated by the electric signal, a mark for displaying a test result on the connector, and a counter operated by the electric signal to count the number of non-defective connectors inspected. It is characterized by having.

According to the present invention, the marker is operated by an electric signal indicating the inspection result from the inspection jig, and a mark indicating the inspection result is attached to the connector. Can be accurately marked, and it is possible to prevent forgetting to attach a mark and mistakenly attaching the mark. Further, since the number of non-defective connectors of the inspected connector is counted based on the electric signal from the inspection jig, non-defective products are packed in an accurate number in a bag, so that the number of bags can be prevented from being excessive or insufficient.

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a configuration diagram of an embodiment of a connector inspection system according to the present invention. In FIG. 1, reference numeral 20 denotes an inspection jig for conducting a continuity inspection of the male terminal of the connector, reference numeral 40 denotes a control box for inputting an electric signal from the inspection jig 20, and reference numeral 50 denotes a connector based on an electric signal output from the control box 40. A marker 60 for marking the inspection result is a counter for counting the number of non-defective connectors based on an electric signal output from the control box 40.

The inspection jig 20 has a structure as shown in FIGS. 2 (a) and 2 (b). 2A and 2B, reference numeral 21 denotes a base frame, and reference numeral 22 denotes a connector holding unit attached to the base frame 21, which holds a connector 31 to be inspected. Reference numeral 23 denotes a pin receiving portion that moves in the left-right direction in the figure along a guide key 32, and is urged leftward in the figure by a coil spring 30 attached to a guide shaft 27 fixed to the base frame 21. Is not in the position shown in FIG. Also, the pin receiving portion 23
Is provided with a fitting recess for fitting to the tip of the connector 31, and the fitting recess is provided in the fitting recess for conducting the conduction test.
Is provided. 26 is rotated in the clockwise direction (arrow A) in FIG.
3 is an operation lever that is brought into contact with the left end portion and moves the pin receiving portion 23 rightward in FIG. The operation lever 26 rotates about the pivot pin 28, and when not operated, is stopped by a lever stopper 29 as shown in FIG.

To check whether the male terminal 39 of the connector 31 is properly mounted on the connector housing, the connector 31 is mounted on the connector holding portion 22 and the operation lever 2 is mounted.
6 is rotated in the clockwise direction (arrow A) in FIG. As a result, the pin receiving portion 23 moves rightward in the drawing against the urging force of the coil spring 30 attached to the guide shaft 27, and the fitting concave portion of the pin receiving portion 23 fits into the distal end portion of the connector 31. I do. At this time, when the male terminal 39 is normally mounted, the conductive pin 24 is previously set so that the male terminal 39 contacts the conductive pin 24 and the male terminal 39 and the conductive pin 24 are electrically connected. Position it in advance. And then
The male terminal 39 comes into contact with the conductive pin 24, and is electrically connected to the male terminal 3.
9 and the conduction pin 24 conduct, thereby detecting that the male terminal 39 is properly mounted.

The control box 40 shown in FIG. 1 outputs a desired electric signal from an output terminal 42 in response to an electric signal to an input terminal 41.

The marker 50 in FIG. 1 uses an electromagnetic solenoid, and has a stamp 52 attached to the tip of a shaft 51 that performs a stroke operation. The marker 50 causes the shaft 51 to perform a stroke operation electrically by an electric signal,
Mark 1

The counter 60 in FIG. 1 counts the electric signals and displays the count data on the display unit 61.

This embodiment is characterized in that the inspection jig 20,
Control box 40, marker 50, and counter 6
0 is systematized. That is, as shown in FIG. 1, the electric wires 24 connected to the conductive pins 24 of the inspection jig 20.
a, and the electric wire 39 a connected to the male terminal 39 of the connector 31 attached to the inspection jig 20 is connected to the input terminal 41 of the control box 40. The output terminal 42a of the control box 40 and the marker 50 are connected by an electric wire 53, and the output terminal 42b and the counter 60 are connected by an electric wire 62.

The system of the present embodiment operates as follows. 1) The connector 31 is mounted on the inspection jig 20 and the operation lever 26 is manually rotated in the direction of arrow A in FIG. 2) When the male terminal 39 of the connector 31 is properly mounted, the male terminal 39 contacts the conductive pin 24, the male terminal 39 and the conductive pin 24 are electrically connected, and the electric wires 24a and 39a are connected. The connection is conducted, and an electric signal is input to the control box 40. 3) The control box 40 outputs an electric signal for operating the marker 50 from the output terminal 42a through the electric wire 53 according to the electric signal. In addition, the output terminal 42b connects the electric wire 62
An electric signal for operating the counter 60 is output through the counter. 4) The marker 50 is activated by an electric signal from the control box 40, and the shaft 51 performs a stroke operation to mark the connector 31. Also, the counter 60
The electric signal from the control box 40 is counted, and the count data is displayed on the display unit 61. The connector 3
