Abstract
Description
Technical Field
[0001] This utility model relates to the field of aircraft connector testing technology, specifically a testing fixture for aircraft connectors. Background Technology
[0002] Aviation connectors, also known as aviation plugs, are electrical connectors specifically designed for the aviation industry. They were first widely used in aviation, hence the name, and have gradually expanded to other fields with high reliability requirements. Their main function is to achieve stable transmission of current or signals through the contact between the socket and the pin. These connectors typically have a metal shell and internal conductive components to ensure a strong and stable connection.
[0003] Currently, in the production process of aviation connectors, it is usually necessary to check whether the internally installed pins are missing or properly inserted. Since the traditional method often relies on visual inspection by personnel, the inspection efficiency is low, and visual fatigue is easy to occur during long-term work, which can lead to missed inspections and increase the defect rate of the product output. Utility Model Content
[0004] The purpose of this utility model is to provide a testing fixture for aircraft connectors, which can quickly test the PIN pins in the aircraft connectors, effectively improving the efficiency of the testing operation, and bringing great convenience to the daily work of personnel.

The overall operation is convenient and fast, effectively improving the efficiency of the testing operation and bringing great convenience to the personnel's testing work.
[0025] Example 2:
[0026] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, a positioning frame 2 is fixedly connected to the middle of the top of the workbench 1. There are five positioning frames 2, and the distance between two adjacent positioning frames 2 is equal. Guide slide rods 4 are fixedly connected to both ends of the top of the inner cavity of the support frame 3. The surface of the movable cross plate 6 is movably connected to the surface of the guide slide rod 4. A limit plate is fixedly connected to the bottom of the guide slide rod 4. Guide slots 22 are opened on both sides of the contact rod 14. A guide plate 21 is fixedly connected to the upper end of the inner cavity of the guide sleeve 15. The surface of the guide plate 21 is movably connected to the upper end of the guide slot 22. A second spring 23 is fixedly connected between the bottom of the guide plate 21 and the bottom of the inner cavity of the contact rod 14. A first spring 20 is fixedly connected between the middle end of the bottom of the inner cavity of the insulating seat 19 and the bottom of the second conductive contact plate 18. A maintenance plate 9 is fixedly installed on the right side of the outer surface of the operating box 5 by screws. The maintenance plate 9 is rectangular in shape. Accommodation slots 11 are opened on both sides of the work box 7. The upper end of the movable frame 8 is movably connected to the surface of the accommodation slot 11.
[0027] In this technical solution, the positioning frame 2 effectively positions the aviation connector to be tested placed on the top of the workbench 1, preventing displacement and misalignment of the aviation connector during testing. The guide slide 4 and the limiting plate guide and limit the moving horizontal plate 6, preventing tilting during movement. The guide slot 22, guide plate 21, and second spring 23 effectively limit and guide the guide sleeve 15 and the contact rod 14, preventing rotation of the contact rod 14 during movement. The second spring 23 is compressed during the upward movement of the contact rod 14, generating tension on the contact rod 14 so that it can move downward and reset. The first spring 20 provides effective elastic support for the bottom of the second conductive contact plate 18. The inspection plate 9 facilitates maintenance and repair work inside the control box 5. The receiving slot 11 accommodates the moving frame 8.
[0028] The working principle of this utility model is as follows: The workbench 1 provides effective support for the aircraft connector to be tested. When testing the aircraft connector, starting the drive motor 10 rotates the screw 12 along the bearing on the work box 7. The rotation of the screw 12 moves the moving frame 8, the moving cross plate 6, and the operating box 5 downwards. During the movement of the operating box 5, the guide sleeve 15 and the contact rod 14 move downwards, allowing the contact rod 14 to pre-contact the top of the PIN pin inside the aircraft connector. Then, with the continuous movement of the operating box 5, it contacts the top of the aircraft connector, allowing the PIN pin inside the connector to support the contact rod 14. This allows the contact rod 14 to move along the surface of the guide sleeve 15. The movement of the contact rod 14 moves the insulating seat 19 and the second conductive contact plate 18, allowing each set of second conductive contact plates 18 to respectively... The indicator light 13 contacts the bottom of the two sets of first conductive contact plates 17, thereby enabling the circuit of the indicator light 13 to be connected to the external battery through multiple sets of first conductive contact plates 17 and second conductive contact plates 18. This causes the indicator light 13 to light up, indicating to the personnel that the PIN pins of the aircraft connector are of acceptable quality. If the PIN pins inside the aircraft connector are missing or not properly inserted, the corresponding contact rod 14 will not be able to make contact between the second conductive contact plate 18 and the first conductive contact plate 17 during movement, causing the circuit of the indicator light 13 to fail to connect and light up. This indicates to the personnel that there is a PIN pin quality problem with the aircraft connector, allowing personnel to discover it in time and take appropriate action. With the overall cooperation, this testing fixture for aircraft connectors can simultaneously test the PIN pins of multiple sets of aircraft connectors. The overall operation is convenient and quick, effectively improving the efficiency of the testing operation and bringing great convenience to the personnel's testing work.
