Shield ground spring and connector and connector assembly using the shield ground spring

Abstract

The invention relates to a shielding grounding spring, a connector employing the same, and a connector assembly. The shielding grounding spring comprises an annular body, and the annular body is provided with a grounding spring inner hole, wherein the grounding spring inner hole is used for the inserting of a housing of a corresponding adaptive connector from the front to the back. The annular body is provided with a plurality of spring pieces which are arranged along the peripheral direction at intervals, face the center of the grounding spring inner hole to extend in a suspension manner and are used for the sliding top-pressure cooperation with the housing of the adaptive connector. The annular body is provided with a plurality of U-shaped clamping pieces which are arranged at intervals along the peripheral direction. Each U-shaped clamping piece is provided with a clamping mouth which faces the direction departed from the center of the grounding spring inner hole. The invention also provides the shielding grounding spring which can be reliably fixed with the housing of the connector, the connector employing the shielding grounding spring, and the connector assembly.

Description

Technical field [0001] The present invention relates to a shielding ground spring and a connector and a connector assembly using the shielding ground spring. Background technique [0002] LRM is the first letter of Line Replaceable Module, which translates to field replaceable module or field replaceable module. LRM series connector is a modular rectangular hybrid connector, which can realize optical, radio frequency, differential and electrical between equipment The integrated transmission of this signal meets the functional requirements for reliable transmission of high-speed data and high-frequency data, as well as the functional requirements for power distribution between boards and sub-board systems. In order to meet the needs of replacement, the LRM connector assembly includes a plug module shell, a plug connector, a socket connector and a chassis panel. The plug connector is installed on the plug module shell, the socket connector is installed on the chassis panel, and the...

Problems solved by technology

[0003] With the change of the use environment, more and more users require that the LRM connector can realize the requirements of sealing and circumferential shielding at the same time. Due to the small size of the LRM product, how to realize the complete sealing and better shielding of the product becomes a problem. A technical problem that is difficult to solve. When the existing shielding grounding spring is used, it is directly welded and fixed on the wall of the inner hole of the socket housing. This has the following problems. The shielding grounding spring is not easy to locate during the welding process. , due to the contact friction between the plug shell and the shielding ground spring, the welding point between the shielding ground spring and the socket shell is opened, and the shielding ground spring moves relative to the socket shell, which causes the shielding ground spring and the socket shell to not be well connected. contact, which may eventually cause the shield to ground to fail
