Anti-loose sealing electric connector special for case

Abstract

The invention discloses an anti-loose sealing electric connector special for a case. The electric connector comprises a plug shell and a socket shell matched and plugged with the plug shell, a pin assembly is assembled in the plug shell through a pin insulator in a sealed mode, a jack limiting glass body is installed in the socket shell, and a plugging hole body assembly is installed on the jack limiting glass body in a limiting and matched mode; and a connecting ring is arranged outside the plug shell, the socket shell sequentially comprises a threaded pipe column A, a threaded pipe column Band a case matching body, the connecting ring consists of a sleeving part and a threaded part, a locking nut is in threaded connection with the outer part of the threaded pipe column B, and an annularlimiting step is arranged at the end part of the case matching body. Electric plugging between electronic components inside and outside the case can be realized, the connection tightness and the sealing performance between the socket shell and the case assembly are improved, an exposed area cannot appear at the case connection position after the socket shell and the plug shell are plugged, the safety and the sealing performance are enhanced, and the external interference condition is also prevented.

Description

technical field [0001] The invention relates to the technical field of electrical connectors, in particular to an anti-loosening and sealing electrical connector specially used on a chassis. Background technique [0002] An electric control cabinet or other equipment with a cabinet often needs to be installed with several connectors, and the electrical connection with other external electronic components or electronic devices is realized through the connectors. In the prior art, connecting holes are usually opened at the positions where the chassis needs to be connected, and connectors are installed at the positions of the connecting holes to realize electrical connection with external components. Since the positions of the connecting holes are exposed, this will lead to the overall sealing of the chassis. Performance, security, and anti-interference are all weakened. The plug and socket of the existing connector are easily separated from each other by external impact or ot...

AI Technical Summary

Problems solved by technology

In the prior art, connecting holes are usually opened at the positions where the chassis needs to be connected, and connectors are installed at the positions of the connecting holes to realize electrical connection with external components. Since the positions of the connecting holes are exposed, this will lead to the overall sealing of the chassis. Safety, security, and anti-interference are all weakened

The plug and socket of the existing connector are easily separated from each other by external impact or other forces, resulting in the defect of disconnection of the connector, and the existing connector is not provided with an anti-loosening mechanism, which leads to the failure of the connector plug and the socket. Very easy to loosen and fall off

[0003] With the improvement of the performance requirements of the whole machine, there are higher and higher requirements for the sealing performance, vibration resistance and shock resistance performance of the connector and the connector installation position. The overall requirements of equipment with a chassis, while traditional connectors are difficult to cope with increasingly harsh environments, it is imminent to propose new connector solutions
