Abstract

The invention relates to a shielding element and an electrical connector plug using the same. The shielding element comprises a shielding sleeve and a clamping sleeve, wherein the clamping sleeve is used for clamping a shielding layer of a cable, and is conductively connected with the shielding layer of the cable; cable channels communicated with each other are formed on the shielding sleeve and the clamping sleeve; the front end of the shielding sleeve is provided with a contact part for conductively connecting an electrical connector shell; the clamping sleeve comprises a permanent seat integrally connected to the rear end of the shielding sleeve and a pressing plate for buckling with the permanent seat to clamp the shielding layer of the cable inserted into the cable channels; and a tile-shaped concave surface is formed on at least one of the pressing plate and the permanent seat. The shielding element provided by the invention can be sleeved to the tail end of an electrical connector, conductively connected with the shielding layer of the cable by the clamping sleeve and conductively connected with the electrical connector shell by the shielding sleeve, so the shielding layer of the cable can be effectively connected by the electrical connector shell and prevented from shielding failure at the wiring position of the electrical connector, thereby effectively solving the problem that the conventional electrical connector cannot prevent lightning.

Description

technical field [0001] The invention relates to the technical field of electrical connectors, in particular to a shielding member and an electrical connector plug using the shielding sleeve. Background technique [0002] With the rapid development of science and technology, people are becoming more and more aware of the dangers of lightning, especially in circuit transmission, lightning protection has become an important factor that has to be considered. At present, in order to prevent the damage of lightning, people A common practice is to set a shielding layer outside the wires of the cable to prevent lightning from damaging the circuit. Electrical connectors are key components for connecting power supplies and electrical equipment. With the rapid development of communication technology, electrical connectors The application in the field is becoming more and more extensive. At present, there are various electrical connectors for electrical connection in the communication f...
