Embodiment Construction

[0022] Example 1 of the shield of the present invention, such as figure 1 As shown, there is a shielding sleeve 1, which is provided with an opening 2 (of course, it can also be a card slot in other embodiments) for engaging with an electrical connector. The front end of the shielding sleeve 1 is provided with an electrical connection The contact part of the connector housing conductively connected, the contact part is the front end surface of the shielding sleeve; the front end of the shielding sleeve 1 has two relief areas on its sleeve wall in the circumferential direction, and the shielding sleeve 1 has two relief areas. There are respectively a first relief gap 3 and a second relief gap 3'extending to the front face of the shield sleeve. The relief gaps are used for the crimping screws of the power supply connector to pass through. The back end of the shield sleeve 1 is integrated conductively connected with The hoop is used to hoop the outer circumference of the shielding ...

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 shield and an electrical connector plug using the shield 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 the transmission of circuits, lightning protection has become an important factor that has to be considered. At present, in order to prevent the destruction of lightning, people A common method is to install a shielding layer outside the wires of the cable to prevent lightning damage to the circuit. Electrical connectors are the key components for connecting power and electrical equipment. With the rapid development of communication technology, electrical connectors are communicating The application in the field is becoming more and more extensive. At present, there are various electrical connectors for electrical connection in the communica...
