Description

Technical Field

[0001] This application relates to the field of electrical connector manufacturing technology, and in particular to a quick assembly device for rectangular electrical connectors. Background Technology

[0002] Electrical connectors are essential and crucial basic electromechanical components in various engineering systems, primarily used for transmitting and controlling electrical signals, as well as connecting electrical components to each other. They are widely used, numerous, and of vital importance in fields such as weaponry, aviation, aerospace, communications, and automotive manufacturing. Rectangular electrical connectors consist of a plug and a socket, achieving circuit connection and disconnection through the mating and disassembly of the plug and socket. Currently, rectangular electrical connectors employ various connection methods, mainly including rack-mount connections, screw-locking connections, and center-screw connections. Rack-mount connections are direct-insertion connections, where the plug and socket are respectively mounted on the rack and unit assembly of the electrical equipment, relying on the movement of the unit assembly to achieve connection and disassembly. Screw-locking connections offer advantages such as simple processing, low manufacturing cost, and wide applicability, but their connection speed is relatively slow. Center-screw structures achieve connector mating and disassembly through screw sleeves and screws respectively mounted on the plug and socket. However, all of the above connection methods have certain limitations, especially unsuitable for applications requiring frequent plugging and unplugging and rapid connection. In practical applications, many products, especially underwater attack unmanned aerial vehicles (UAVs), require functional testing. During testing, the test equipment and the product under test (DUT) are typically connected via various cables to transmit and control electrical signals. In batch testing, the insertion and removal of rectangular electrical connectors is particularly frequent. However, in existing technologies, the connection and disconnection of rectangular electrical connectors mostly rely on manual operation. This requires forcefully inserting the connector's plug or socket into the socket or plug on the DUT, and then forcefully pulling it out after testing. This method is not only labor-intensive and inefficient, but also fails to meet the needs of rapid connection.

[0003] Therefore, there is an urgent need for a rectangular electrical connector structure that can achieve rapid connection and disconnection to improve work efficiency, reduce operational difficulty, and meet the needs of special application scenarios. Utility Model Content
