Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of general-purpose adjustable torque of circular connector, which is a kind of connector shell of same shell number and different key position can be adapted by key groove wall and outer protection wall;Different shell number connector shell can be adapted by replacing key groove wall and outer protection wall;The tightening torque is adjusted by pre-tightening force push rod, and the safe torque when adapting different shell is adapted. BACKGROUND

[0002] The circular connector is widely used in aerospace systems, and there are many types of connector shells, and the same shell number has multiple key positions. During the production of cable assemblies, each type of shell number and key position combination needs to be matched with the corresponding shell as a disassembly tool, increasing material costs and management costs. In addition, the torque is difficult to control during the assembly and disassembly process of the ordinary tool, and the torque may be too large to damage the connector. Therefore, a general-purpose disassembly tool with high universality and controllable torque is needed. SUMMARY

[0003] To solve the problem of the large number of existing circular connector tool shells, the inconvenience of carrying out tasks in the field, and the uncontrollable torque that may damage the product. The utility model provides a new general-purpose adjustable torque disassembly tool for circular connectors. The tool is adapted to the connector shell of the same shell number and different key positions by key groove wall and outer protection wall. Different shell number connector shells can be adapted by replacing key groove wall and outer protection wall. The tightening torque is adjusted by pre-tightening force push rod, and the safe torque when adapting different shell is adapted, meeting the needs of production.

[0004] The utility model solves the technical problems by adopting the following technical solutions: the tool is adapted to the connector shell of the same shell number and different key positions by key groove wall and outer protection wall. Different shell number connector shells can be adapted by replacing key groove wall and outer protection wall. The tightening torque is adjusted by pre-tightening force push rod, and the safe torque when adapting different shell is adapted.

[0005] The utility model has the advantages that only one set of key groove wall and outer protection wall is needed to adapt the assembly and disassembly of multiple key position connector shells of the same shell number. By replacing the key groove wall and outer protection wall, all circular connector shells can be adapted. The tightening torque is adjusted and the color change of the observation hole is observed to realize the safe assembly and disassembly of the circular connector, with the characteristics of small size, full function and high safety.

[0018] The keyway wall (1) is inserted into the outer protective wall (2), the fixed magnet (4) is installed in the countersunk holes at both ends of the support rod (3), the support rod (3) is inserted into the rectangular hole below the keyway wall (1) and the outer protective wall (2), the outer protective wall (2) is installed into the torsion bearing (5), the torsion bearing (5) is installed into the universal housing (6), the preload push rod (7), the preload spring (8), and the top cap (9) are arranged in sequence on the preload retainer (11), the preload retainer (11) is fixed inside the universal housing (6), the preload push rod (10) is inserted into the threaded hole above the universal housing (6) and rests on the top cap (9), the bottom plate (12) is at the bottom of the universal housing (6) and is fastened with screws.

[0019] The keyway wall (1) can be adapted to housings with different key positions of the same housing size. By replacing the keyway wall (1) and the outer protective wall (2), housings of different housing sizes can be adapted. By adjusting the preload push rod (10) to press against the top cap (9), compressing the preload spring (8), and pushing the preload push rod (7), when removing the tail cover of the round series connector, the torque bearing (5) rotates slightly and presses against the preload push rod (7). At this time, the green block on the torque bearing (5) can be seen through the small round observation hole on the universal housing (6). When the torque is too large, the preload spring (8) is compressed by the preload push rod (7), and the torque bearing (5) rotates further. At this time, the red block on the torque bearing (5) can be seen through the small round observation hole on the universal housing (6). At this time, the force should be stopped to prevent damage to the connector. The tightening process is similar to the removal process, and the structure is maintained by the preload on the other side. By adjusting the preload push rod (10) to push the top cap (9), the edge of the top cap (9) is aligned with the different torque marking positions of the rectangular observation hole on the universal housing (6), so as to achieve precise control of torque when assembling and disassembling different housings and reduce the possibility of connector damage due to excessive torque.
