Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention inspects the fitting state of a connector, and inspects the housing state of terminal fittings arranged on the connector, and determines whether the inspection is successful. The present invention relates to a connector terminal fitting detection tool and a connector terminal fitting detection method to be confirmed after an inspection. 2. Description of the Related Art FIG. 16 is a perspective view of a connector terminal detector 23, and FIG.
7 is a cross-sectional view showing the inside of FIG. 7. By rotating a cam lever 53, a guide shaft 47 on which a compression coil spring is mounted is slidably inserted, and the detector main body 33 moves to the connector receiving portion 31 side and contacts therewith. Let go. As a result, the continuity inspection pin 57 connected to the power supply 63 built in the inspection recess 59 of the detector main body 33 comes into contact with and separates from the connector 27 attached to the connector receiving portion 31, and the continuity inspection of the connector terminal is performed. . On the other hand, the detector main body 33 is provided with a fixing hole 97 opened on the upper surface side, and a pen 95 is fixed. In this case, the pen point 93 is slightly protruded into the inspection concave portion 59, and when the detector main body 33 is moved to the connector receiving portion 31 side to fit the connector 27 into the inspection concave portion 59, the fitting operation causes Mark 1 indicating on the upper surface 27b of the connector 27 that the connector 27 has been tested for continuity.
13 is described. When conducting continuity inspection of the connector 27, the terminal fitting 6
In a state in which the cam 7 cannot be engaged with the locking spacer 73 because it is partially inserted into the terminal accommodating chamber 69, the detector main body 33 can be moved to the connector receiving portion 31 side even when the cam lever 53 is operated. Since it cannot be performed, it is possible to detect that the locking spacer 73 is incompletely mounted on the connector 27, that is, that the terminal fitting 67 is half-inserted into the terminal housing chamber 69. [0005] In the prior art, the end mark 113 indicating that the continuity test has been completed is provided with the detector main body 33 for connecting the connector 27 to the test recess 59. The movement of the connector 27 to the side of the connector 31 is indicated on the upper surface 27b of the connector.
9 is half-inserted state and even if it is actually a defective inspection,
Since the movement of the detector main body 33 is performed halfway, the completion mark 113 is written on the upper surface portion 27b of the connector. It is difficult to identify good products. On the other hand, a connector that has passed the continuity test due to good fitting with the detector indicates that the test has been completed as a passing product even if the continuity test is poor due to current interruption due to disconnection of the terminal. Since the completed mark 113 is already written on the connector upper surface portion 27b, it is not possible to confirm whether the inspection is good or defective after the inspection. In the inspection according to the prior art, the continuity inspection of the connector terminal is mainly performed as the final inspection.
It is difficult to early detect a terminal mounting defect and a mating defect of a connector in the middle of a production line, and when there are a plurality of connector production lines and a product to be inspected is mixed, a defective product is inspected during the continuity inspection. It is difficult to specify which production line is used even if a product is found. [0008] Therefore, the present invention enables random and easy inspection of connector terminal fitting anywhere on a production line, and confirms whether the inspection is good or defective after completion of the fitting inspection. It is an object of the present invention to provide a connector terminal fitting detecting tool and a connector terminal fitting detecting method capable of confirming a housing state of a terminal fitting of a connector by providing a display means capable of detecting the connector terminal fitting.

When the connector 2a is bent by contacting the detection pin 4, the lock 5 does not engage with the locking pit 6 and is not locked by the detector 1a, so that no lock sound is generated and the connector front end face 14
Due to the formation of a gap between the connector 9 and the detector fitting portion 15, the end mark 17 of the pen 9 is not written on the front end face 14 of the connector. From this, it is possible to reliably detect that the connector 2a is not fitted to the detector 1a, that is, that the connector 2a is not properly accommodated in the terminal fitting, and that the connector 2a is in the terminal fitting test. It is easily confirmed after the inspection that the product is defective and has not passed the inspection. FIG. 11 is a sectional view of the detector 1b, and FIG.
2 is a perspective view of the connector 2b. The display means is a projection-like claw 10 provided integrally with the detection tool 1b and protruding from a fitting portion 15 of the detection tool 1b, which abuts on the front end surface 14 of the connector. A mark is displayed on the connector front end surface 14 only when it is confirmed that the terminal fitting inspection is good by being fitted and locked, and after the inspection is completed, it is ensured that the connector 2b is a good inspection product. You can check. FIG. 13 is a cross-sectional view showing a state in which the connector 2b is mounted on the detector 1b. Since the terminal fittings of the connector 2b are well mounted, the detection pins 4 are inserted into the terminal receiving chamber 16 without any trouble. Then, the lock 5 of the connector 2b is

Locked to. At this time, the locking sound generated at this time confirms that the fitting inspection of the connector 2b is good, and at the same time, the indentation 18 indicating that the inspection is non-defective is formed as a recess on the connector front end face 14 by the projection-like claw 10. In rare cases, it is possible to easily confirm that the connector 2b has completed the inspection as a non-defective product after the inspection. FIGS. 14 and 15 are sectional views showing a state in which the connector 2b is half-inserted into the detector 1b.
When the connector 2b is bent by contacting the detection pin 4, the lock 5 does not engage the locking pit 6 and is not locked by the detector 1b.
Due to the formation of a gap between the connector 4 and the detector fitting portion 15, the mark 18 formed by the projection-like claw 10 is not displayed on the front end face 14 of the connector. This means that the connector 2b is not fitted to the detector 1b, that is, the connector 2b
It is possible to reliably detect that the housing state of the terminal fitting is defective, and to easily confirm after completion of the inspection that the connector 2b is defective in the terminal fitting inspection and has not passed the inspection. . As shown in FIG. 1 to FIG. 4, a notation tool for indicating on the front end face 14 of the connector 17 that the fitting inspection is good is a fixing tool penetrating the detection tool 1a. By changing the shape and size of the hole 7, it can be applied to writing tools other than the pen 9. In the above embodiment, the example of the connector terminal fitting detecting tool for inspecting the fitting of the female connector has been described. The invention can be applied. As described above, according to the first aspect of the present invention, when the connector is locked by the detector and the terminal metal fitting is in a good state and complete fitting of the connector is detected. Only by providing a display means on the front end of the connector with a mark indicating that the connector inspection is good on the front end face of the connector, it is easy to distinguish between a good inspection product and a defective product after the inspection. You can check. According to the first aspect of the present invention, since the display means is a projection-like claw, the mark indicating that the fitting inspection is good is provided. It is displayed on the front end face of the connector as a dent, so it can be easily distinguished from the end mark by a pen and there is no fear that the display will disappear due to friction like ink, and it is easy to distinguish between good and defective products after inspection Can be confirmed. According to the first aspect of the present invention, the projection-like claw, which is the notation tool, is provided integrally with the detection tool main body so as to protrude from a fitting portion of the detection tool abutting on the front end face of the connector. Therefore, the connector front end face can be brought into contact with the notation tool only when the inspection is good and the connector is completely fitted to the detection tool. [0040]
