Shielding tail cover

Abstract

A shielding tail cover comprises a tail cover shell, a lining, a limiting sleeve, a crimping cylinder, a wire clamp and a screw, wherein a first step hole is formed in the tail cover shell, the lining is a tubular body internally provided with a step hole and externally provided with a cylinder, the limiting sleeve is a cylindrical body in which a plurality of wire core holes are formed, the lining is inserted into the wire core holes of the limiting sleeve, the limiting sleeve is arranged in the first step hole of the shell, the crimping cylinder sleeves an outer side of the lining, and two semi-circular arches of the wire clamp are buckled outside the crimping cylinder and are fastened by the screw. With a structure of arranging the lining in the shell, the problem of cable grounding is solved; the limiting sleeve is used for limiting axial movement of a cable; and with the adoption of the structure of the crimping cylinder and the wire clamp, the cable and the shell are fixed in a radial direction of the cable, so that the cable is stable and firm in connection, the phenomena that the cable is damaged and the shielding layer is damaged are prevented, and the shielding tail cover has the advantages of good shielding performance and high electromagnetic interference prevention capability.

Description

technical field [0001] The invention relates to the technical field of electric connectors and a device for shielding and fixing armored cables at the tail end of a connector, in particular to a shielding tail cover. Background technique [0002] With the rapid development of electronic equipment, in order to ensure information security, electronic jammers are also widely used in the field of communication and aerospace. In the electronic equipment of the prior art, the shielding grounding technology connected with the connector is mature, and the shielding sheath technology of the cable is correspondingly mature. And the problem of the connection strength of the cable has not been effectively solved. [0003] Because the electronic jammer itself releases high-power interference signals, it is required that the electronic equipment must use shielded connectors and configure shielded cables. Due to the defects of the tail cover clips of the shielded connectors, the existing ...

AI Technical Summary

Problems solved by technology

In the electronic equipment of the prior art, the shielding grounding technology connected with the connector is mature, and the shielding sheath technology of the cable is correspondingly mature. And the connection strength of the cable has not been effectively solved

[0003] Because the electronic jammer itself releases high-power interference signals, it is required that the electronic equipment must use shielded connectors and configure shielded cables. Due to the defects of the tail cover clips of the shielded connectors, the existing clips cannot be well grounded and the cable shielding layer The clamping force of the clamp is not enough, resulting in improper force application of the cable clamp. If the clamp is excessively clamped, the cable will be damaged. If the clamping force of the clamp is insufficient, the cable will come out, resulting in damage to the cable and damage to the shielding layer. intensified
