Description

Technical Field

[0001] This utility model relates to a tooling, specifically a tooling for detecting needle retraction. Background Technology

[0002] The connection of wire harnesses is mainly achieved by plugging in the male and female terminals of connectors. The reliability of the connection largely determines the stability of the circuit connection. If the retraction of the connector terminals is not detected in time, there is a risk of increased contact resistance and even damage to the machine. Currently, the connection effect is basically checked manually, following the four-step principle of "insert, listen, pull back, and look," emphasizing the importance of "pull back." Since the effectiveness of the pull-back action depends on the operator's skill level, the terminal retraction status is basically judged by the operator's pull-back operation, which indirectly leads to the risk of terminal retraction of connectors. The existing operation method mainly relies on the operator's awareness and skill in confirming the operation, using sound and mechanical force to assist in judgment. This results in low production efficiency, a high error rate, and a low quality level, making it impossible to guarantee 100% product quality.

[0003] Currently, a utility model patent with publication number CN208419795U discloses a connector pin retraction inspection fixture, including a detection body. The detection body consists of a detection insertion part, a cylindrical stop part, and a cylindrical handle part distributed from left to right. A positioning key is formed on the outer surface of the detection insertion part. Several detection holes are formed on the left end face of the detection insertion part. A compression spring is formed on the bottom surface of the detection holes. A detection head is fixed to the left end of the compression spring. The detection head slides left and right within the detection holes. Advantages of this utility model: simple operation, thorough inspection, and high inspection efficiency.

[0004] As can be seen from the above-disclosed technical content, as prior art, the utility model with announcement number CN208419795U uses the shape of the detection insertion part and the positioning key of the tooling to match the shape of the product to be inspected, and the position of the detection hole is set according to the position of the product pin. However, this patent can only be applied to the testing of one type of connector, and it is not flexible enough in use. Utility Model Content

One end of the module sliding seat has a fixed tube for mounting the connector module, and the other end of the module sliding seat is connected to the fixing bolts via a spring. Fixing bolts are provided on the upper surface of the main body. A detection correctness indicator buzzer and a detection travel indicator buzzer are fixedly mounted on the upper part of the main body. A connector module fixing lever is provided at the opening of the connector module's insertion part. An inlet hole is provided at the connection between the base plate and the main body.

The connector module fixing lever 9 is provided at the opening of the connector module 1. The wire inlet hole 8 is provided at the connection between the base plate 2 and the main body device 3. A proximity switch is provided below the module sliding seat 5.

[0016] A connector pin removal inspection fixture (hereinafter referred to as "the patent") with utility model announcement number CN208419795U uses the shape of the detection insertion part and the positioning key of the fixture to match the shape of the product to be inspected. The position of the detection hole is set according to the position of the product pin. However, the patent can only be applied to the testing of one type of connector, which is not flexible enough. The present invention, through the replaceable connector module 1, enables the fixture to adapt to a variety of connectors.

[0017] To further optimize the working efficiency of this application and enable the equipment to provide a stable operating platform, the base plate 2 has multiple fixing holes 4.

[0019] When this utility model is used, its specific operation is as follows: This device supplies power to the connector module 1, the correct detection indicator buzzer 6, and the detection travel indicator buzzer 7 via an external power supply through the inlet hole 8. First, the connector module fixing lever 9 is moved to insert the connector to be tested into the connector module 1. The connector module fixing lever 9 is then released to fix the connector in the connector module 1. The wire with the crimped terminal is inserted into the connector hole of the connector module 1, and the connector module 1 is fixed on the module sliding seat 5. At this time, the wire is pulled, and the connector module 1 and the module sliding seat 5 begin to move. When the module sliding seat 5 moves, the spring 11 is stretched, and the correct detection indicator buzzer 6 sounds. At the same time, if it moves further, the detection travel indicator buzzer 7 sounds, indicating that it cannot be pulled any further, otherwise the internal structure of the connector will be damaged. The wire is then released, and the connector module 1 and the module sliding seat 5 return to their initial natural state under the tension of the spring 11 and are limited by the starting bolt 10. The correct detection indicator buzzer 6 and the detection travel indicator buzzer 7 are controlled by a proximity switch located below the module slide base 5. Meanwhile, the connector module 1 can be replaced with different connectors to ensure multiple types of product testing. The main body 3 has four fixing holes 4 for secure placement.
