Description

Technical Field

[0001] The utility model relates to the technical field of electric connectors, in particular to a rectangular aviation socket. Background Art

[0002] Rectangular aviation socket, as a kind of aviation plug, is an electromechanical component that connects electrical circuits. It is widely used in complex industrial environments and outdoor environments such as aviation, aerospace, navigation, national defense, military, and electricity. Rectangular aviation socket is a type of connector developed for application scenarios such as complex industrial environments and outdoor environments. It is formally called "industrial connector". It is mainly used for circuit connection between cables and cables, and cables and equipment of electrical and electronic equipment to realize the transmission of signals and electrical energy.

[0003] In the existing technical solution, a rectangular high-voltage electrical socket connector is proposed, including a shell, a mounting plate installed in the shell, the mounting plate is glued and fixed to the shell, the high-voltage wire and the pin contact are crimped and then installed in the mounting plate, and the tail of the shell also has a blocking rib.

[0004] In order to solve the problem that the mounting plate is easily detached from the rear of the shell during multiple plugging and separation operations, the prior art uses a method of fixing the pin contact and the mounting plate by bonding to ensure good voltage resistance performance. Since there are blocking ribs at the rear of the shell, the blocking ribs of the shell can prevent the mounting plate from detaching from the shell when the socket connector and the matching plug connector are plugged in and separated, but the connection between the plug and the socket is poor, and it is easy to fall off after plugging, which leads to the problem of reduced service life of the rectangular aviation socket.

[0020] By adopting the above technical solution, the function of preventing wrong insertion is achieved through the cooperation between the anti-insertion ring, the assembly plate and the baffle.

[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0022] 1. The utility model provides a rectangular aviation socket. During the plug-in installation process of the base shell and the plug shell, the clamping plate is tightly combined with the top of the locking block, and the connecting column at the bottom of the clamping plate applies pressure on the rubber pad, causing the rubber pad to push the pushing block to move downward along the slide rail after being stressed, and cooperates with the connectivity of the stretching rod to urge the clamping mechanism to perform a downward pressing action, thereby enhancing the effectiveness of the locking mechanism and further improving the protective performance of the plug.
