electrical connector

Abstract

The invention provides an electric connector, comprising: an insulating main body; a shielding piece disposed on the insulating main body; at least one grounding terminal located in the insulating main body, wherein the grounding terminal has a base portion, a first elastic arm is formed by bending and extending upward from the base portion, the first elastic arm is provided with a through groove,the left and right sides of the through groove have two inner side edges, a first contact portion is formed by extending backward from the first elastic arm, an abutting portion is formed by bendingand extending upward from the base portion to abut against the shielding piece, the abutting portion has a free portion, the width of the free portion is less than or equal to the distance between thetwo inner side edges, and the free portion is formed between the two inner side edges; and a plurality of signal terminals located in the insulating main body. The electric connector can shield the crosstalk of the signal terminals and can also reduce the space occupied by the grounding terminal.

Description

【Technical field】 [0001] The invention relates to an electrical connector, in particular to a shielded electrical connector. 【Background technique】 [0002] A shielded connector for electrically connecting a chip module to a circuit board, comprising: an insulating body, and a plurality of signal terminals and a plurality of grounding terminals accommodated in the insulating body, each of the signal terminals has a The first base is bent upward from the top end of the first base to form a first elastic arm, and extends vertically downward from the first base to form a first tail; each of the ground terminals has a second The base is bent and extended upwards from the top of the second base to form a second elastic arm and a crimping arm, the crimping arm is located on one side of the second elastic arm, extending vertically from the second base The lower part is extended to form a second tail portion; an upper shielding sheet, the upper shielding sheet covers the upper surf...

AI Technical Summary

Problems solved by technology

Since the crimping arm of the ground terminal abuts against the upper shielding piece, the crosstalk of the signal terminal can be shielded; however, since the crimping arm is arranged on the second elastic arm of the ground terminal side, so that the setting of the crimping arm increases the width of the ground terminal, resulting in an increase in the space occupied by the ground terminal and an increase in the material of the ground terminal, thereby increasing the production cost of the ground terminal, and in the insulation More grounding terminals and signal terminals cannot be arranged in the limited space of the body, which is not conducive to the transmission of more signals by the shielded connector, and thus is not conducive to improving the performance of the electrical connector
