electrical connector

Abstract

An electrical connector is used for a pair of abutting components to plug backwards and is characterized by comprising an insulation body, at least one upper grounding terminal, at least one lower grounding terminal and a shielding sheet, wherein the at least one upper grounding terminal and the at least one lower grounding terminal are vertically and oppositely arranged on the insulation body, the shielding sheet is arranged between the upper grounding terminal and the lower grounding terminal and is provided with at least one elastic arm, the at least one elastic arm is bent and extends, theelastic arm is provided with a first contact part, a second contact part and a third contact part which sequentially extend, the first contact part is in contact with the upper grounding terminal, the second contact part is in contact with the lower grounding terminal, the third contact part is in contact with the same upper grounding terminal, a first connection part is connected with the firstcontact part and the second contact part, a second connection part is connected with the second contact part and the third contact part to improve elasticity of the elastic arm of the shielding sheet,the contact forces among the elastic arm, the upper grounding terminal and the lower grounding terminal are increased, so that a stable grounding effect is achieved, and the material used for manufacturing the shielding sheet is saved.

Description

Technical field [0001] The invention relates to an electrical connector, in particular to an electrical connector for improving the shielding effect of a shielding sheet. Background technique [0002] As the frequency of electrical connector transmission signals becomes higher and higher, the shielding structure of the electrical connector has a higher standard. The shielding structure is required to have a better and more stable grounding effect to meet the high-frequency transmission performance of the electrical connector Requirements. An existing electrical connector with a shielding structure includes an insulating body. The front end of the insulating body is provided with a mating cavity for the insertion of a mating element. The insulating body is provided with upper and lower rows of terminals. The front ends of the lower two rows of terminals are exposed in the mating cavity to be connected to the mating connector. The upper row of terminals has a plurality of upper gr...

Problems solved by technology

[0003] Since the upper elastic arm and the lower elastic arm are respectively torn and formed by the substrate, they are set separately, the force arm is short, the elasticity is poor, the contact force with the upper and lower ground terminals is weak, the contact effect is unstable, and the substrate area is large, which wastes materials It is also easy to accumulate charges, which affects the shielding effect of the shielding sheet on the interference signal, resulting in the inability of the electrical connector to achieve excellent high-frequency signal transmission performance
