Self-pretightening motion-isolation-type shielding connector

Abstract

The invention relates to a self-pretightening motion-isolation-type shielding connector. A plug comprises a plug shell and a plug contact piece. A socket comprises an outer shell, a socket shell, a socket contact piece, an isolation disk, balls, metal disks and a fixing bolt. One end of the outer shell is opened, the metal disk I, the isolation disk, the metal disk II and the socket shell are sequentially arranged in a cavity of the outer shell from inside to outside, a plurality of through holes are formed in the isolation disk, the balls are arranged in the through holes, installation through holes are formed in the socket shell, the metal disk I, the isolation disk, the metal disk II and the outer shell respectively, and the fixing bolt penetrates through the installation through holes to connect the socket shell, the metal disk II, the isolation disk, the metal disk I and the outer shell. The self-pretightening motion-isolation-type shielding connector can realize blind plugging, realize sealing and shielding through motion isolation, be used between a machine case and a machine frame, and solve the problem that contact pieces are damaged due to the fact that the amplitude of relative motion between a plug and a socket is large.

Description

technical field [0001] The invention relates to the technical field of connectors, in particular to a self-pretensioning motion isolation type shielding connector. Background technique [0002] A connector usually consists of two parts, a plug and a socket, such as figure 1 , 2 , 3, in most electronic equipment, the socket (5') is installed on the frame panel (4'), the plug (2') is installed on the chassis panel (1'), and the pin contact (6') and socket contacts (3') can be mated with each other. Normally, the chassis and the rack are installed together through two fixed points at the front, and for plugging and unplugging, there are two with proper clearance. Due to vibration during use, there must be relative movement between the chassis and the frame and between the plug (2') and the socket (5'), which will cause shaking of the contacts and cause changes in electrical properties , and even cause mechanical damage to the contacts. In addition, in order to solve shie...

AI Technical Summary

Problems solved by technology

Due to vibration during use, there must be relative movement between the chassis and the frame and between the plug (2') and the socket (5'), which will cause shaking of the contacts and cause changes in electrical properties , and even cause mechanical damage to the contacts

In addition, in order to solve shielding and sealing problems, the connector is usually provided with a shielding grounding spring (8') and an O-ring (7'). The shielding grounding spring (8') and the O-ring (7') are actually During use, due to the change of the gap during vibration, the shielding grounding spring (8') and the O-ring (7') are repeatedly subjected to alternating stress, which may cause plastic deformation and failure over time
