Connector capable of preventing pins from being damaged

Abstract

The invention relates to a connector capable of preventing pins from being damaged. The connector comprises a shell, a pin contact piece, and an insulator filled between the pin contact piece and the shell. The inner hole of the shell is provided with an insulating plate with a through hole for a pin to pass through. The peripheral surface of the insulating plate is in a guide fit with the wall of the inner hole of the shell. An elastic piece is arranged between the insulating plate and the insulator. The connector is provided with a forward move limit structure and a backward move limit structure of the insulating plate. The forward move limit structure comprises a guide pillar fixed on the insulating plate. The guide pillar is slidably arranged in the guide hole of the insulator in an anti-dropping manner. The guide pillar is in a guide fit with the guide hole. When the connector is plugged with an adaptive connector, the shell of the adaptive connector can firstly contact the insulating plate. Due to the radial positioning effect exerted by both the inner hole of the shell on the upper end of the insulating plate and the guide pillar on the lower end of the insulating plate, the insulator can be accurately guided along the axis of the shell. Thus, the insulating plate is prevented from deflection relative to the axis of the shell. Meanwhile, since all pin contact pieces pass through the hole in the insulating plate, the bending deformation of the pin contact piece is avoided.

Description

technical field [0001] The invention relates to a connector which can prevent pins from being damaged. Background technique [0002] like figure 1 As shown, during the use of plugs and sockets with large shell sizes, such figure 1 The case where the housing of the plug shown touches the pin contacts of the socket, this contact sometimes bends the pins, and at this time, the bent pins cannot be inserted into the socket accurately, if the plug, If the socket continues to be mated, the pins will be folded into the inner cavity of the socket housing, and the broken pins will be overlapped with other pins, causing a short circuit of the socket. If you want the pins to be protected by the socket housing from being touched, you need to lengthen the front end of the connector housing, such as figure 2 As mentioned above, the project proves that for a plug with an inner diameter of φ55, if the pin is to be scooped-proof, the socket housing must be lengthened by at least 20mm, and...
