Electrical connector

Abstract

The present invention discloses an electrical connector. The electrical connector comprises an insulation body. Multiple terminals comprise an upper row terminal group and a lower row terminal group,and the multiple terminals are fixed on the insulation body. The upper row terminal group comprises at least one first grounding terminal, and the lower row terminal group comprises at least one second grounding terminal. A shielding piece is contained in the insulation body, the shielding piece is located between the upper row terminal group and the lower row terminal group, and the shielding piece comprises at least an opening, a first elastic arm and a second elastic arm, wherein the first elastic arm and the second elastic arm form interlaced arrangement separately from two opposite sidesof the inner edge of the opening. The first elastic arm extends towards the first grounding terminal(s), and the first elastic arm and the first grounding terminal(s) are contacted with each other. The second elastic arm extends towards the second grounding terminal(s), and the second elastic arm and the second grounding terminal(s) are contacted with each other. The extending starting points of the first elastic arm and the second elastic arm are separately a first position and a second position, and the extending end points are separately a third position and a fourth position. The third position is more close to the second position compared with the fourth position to ensure that the elastic arm lengths of the first elastic arm and the second elastic arm are long enough, so that the first elastic arm and the second elastic arm are not prone to fatigue when the first elastic arm and the second elastic arm are contacted with the grounding terminals repeatedly, the durability is enhanced, and the service life is improved.

Description

technical field [0001] The invention relates to an electrical connector, in particular to an electrical connector capable of improving high-frequency problems. Background technique [0002] A known electrical connector, which includes an insulating body and a number of butt terminals fixed to the insulating body, including a plurality of upper row terminals and a plurality of lower row terminals, both of which have grounding terminals. A shielding sheet is arranged between the terminal row and the lower row of terminals, and an opening is arranged on the shielding sheet, and a first elastic arm and a second elastic arm extend from the opening to respectively contact the grounding terminals of the upper row and the lower row to achieve the effect of grounding. Solve high frequency problems. However, the first elastic arm and the second elastic arm extend toward each other on two opposite sides of the inner edge of the opening, so the length of the first elastic arm and the s...

AI Technical Summary

Problems solved by technology

However, there are fewer and fewer existing electrical connectors, so the specifications of the shielding sheet are also fewer and fewer. The length of the first and second elastic arms is only less than or equal to half the width of the opening, and their elasticity is insufficient when they contact the ground terminal. Tired easily, affecting durability and shortening service life
