Embodiment Construction

[0044] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0045] see figure 1 as well as figure 2 As shown, the present invention discloses an electrical connector 100, including a housing 10, several terminal modules 20 mounted on the housing 10, several shielding elements 30, and fixing elements 40 for fixing the terminal modules 20 and base 50 .

[0046] see image 3 as well as figure 1 , figure 2As shown, the housing 10 includes a butt wall 11 and a side wall 12 . The abutting wall 11 and the side wall 12 jointly define a receiving groove 13 for receiving the terminal module 20 and the shielding element 30 . The docking wall 11 is used for mating with a docking connector (not shown), and a number of docking holes 111 are disposed thereon. The docking hole 111 penetrates the docking wall 11 a...

Abstract

The invention provides a shielding element and an electric connector, the shielding element comprises a base part and a butt joint part which is formed by extending outwards from one side of the base part along a first direction, and one side, far away from the base part, of the butt joint part is provided with a butt joint edge; the butt joint part is provided with a short pile grounding prevention contact arm, one end of the short pile grounding prevention contact arm is located on the butt joint edge, and the other end of the short pile grounding prevention contact arm extends towards the base part in the first direction. Compared with the prior art, the shielding element provided by the invention is provided with the anti-stub grounding contact arm, so that the shielding element, the grounding terminal and the grounding terminal of the butting connector are connected to form an integral body, the backflow path of the grounding is improved, the electromagnetic isolation between the differential signal terminal pairs is increased, and the insertion loss and crosstalk are improved.

Description

technical field [0001] The invention relates to the field of connectors, in particular to a shielding element and an electrical connector with the shielding element. Background technique [0002] Backplane connectors are widely used in communication technology. It is a commonly used connector for large-scale communication equipment, ultra-high-performance servers and supercomputers, industrial computers, and high-end storage equipment. The backplane connector usually includes a plurality of signal modules arranged at intervals along the left and right directions, and each signal module includes an insulator, a plurality of differential signal terminal pairs arranged at intervals along the up and down direction and fixed to the insulator, a first shielding member and a second shielding member. The shielding member, the first shielding member and the second shielding member are assembled on opposite sides of the insulating member in a left-right direction. However, the mating...
