Embodiment Construction

[0014] Examples of electrical connectors are Figure 1~5 As shown: it includes a housing 8 with a plug-in end at the front end and a shielding assembly arranged in the housing. The shielding assembly includes a shielding ring 4 and a compression ring 7. The shielding ring 4 includes an axis extending in the front and rear direction in contact with the housing The shielding ring body, the compression ring 7 includes a compression ring body whose axis extends along the front and rear directions, and the front end of the inner hole of the shielding ring body has a shielding wire connection hole section 11, and the shielding wire connection hole section 11 is gradually enlarged from the back to the front In this embodiment, the shielding wire connection hole section 11 is tapered, and the hole wall of the shielding wire connection hole section is spaced around the circumference to be provided with three lengths extending along the front and rear directions and extending to the fron...

Abstract

The invention relates to an electrical connector. The electrical connector includes a shielding assembly having a shielding ring, the shielding ring includes a shielding ring body whose axis extends along a front-back direction, the front end of an inner hole of the shielding ring body has a shielded wire connecting hole segment for insertion of a rear end wire pressing segment on a corresponding hold-down ring in an anastomotic manner from front to back to be in contact connection with a corresponding shielded wire, the shielded wire connecting hole segment is of a flaring structure whose caliber gradually largens from back to front, and at least two wire pressing deformation grooves whose lengths extend along a front-back direction and front ends extend to a front end face of the shielding ring body are arranged at an interval along a circumferential direction on a hole wall of the shielded wire connecting hole segment. The electrical connector provided by the invention solves the problem in the prior art that the hold-down ring cannot elastically press a shielding layer.

Description

technical field [0001] The present invention relates to electrical connectors for electrical signal transmission. Background technique [0002] For electrical connectors, it is necessary to connect the shielding layer of the cable to the housing of the electrical connector to achieve shielding of the cable. The existing common shielding methods mainly include two forms: the outside of the housing and the inside of the housing. The structure connected to the outside of the housing is to connect the shielding layer to the terminal attachment of the electrical connector or the terminal reserved on the housing. This form is not suitable for use in outdoor or other harsh environments. The structure connected inside the shell mostly adopts the form of shielding ring and compression ring. The shielding ring is connected with the shell, and the shielding layer of the cable is compressed and fixed between the compression ring and the shielding ring. The housing is electrically conne...
