electrical connector

Abstract

The invention discloses an electrical connector, which is docked with a mating connector and installed on a circuit board, comprising: a plurality of terminals fixed on an insulating body, the terminals have a contact portion and a conduction portion located behind the contact portion, The contact part is in electrical contact with the docking connector, the conduction part extends out of the insulating body and electrically contacts the circuit board; a grounding shell is covered outside the insulating body; a shielding shell is opposite to each other between a closed position and an open position When the insulating body is rotated, a first end of the shielding shell is electrically connected to the grounding shell. When the shielding shell is in the closed position, a second end of the shielding shell is electrically connected to at least one grounding medium. The grounding medium is installed and It is electrically connected to the circuit board. When the shielding case is in the open position, an observation window is formed between the shielding case and the grounding medium, and the conduction part is exposed in the observation window, which is used to reduce the grounding path of the shielding case and is beneficial to high frequency signal transmission.

Description

【Technical field】 [0001] The invention relates to an electrical connector, in particular to an electrical connector which improves the transmission effect of high-frequency signals. 【Background technique】 [0002] A conventional electrical connector has an insulating body, a plurality of terminals are disposed on the insulating body, and the terminals have a welding portion extending out of the insulating body for welding with a circuit board, and a shielding shell covers the insulating body and is welded to the circuit plate, the welding part extends backward from the shielding shell and the insulating body, and the front end of an auxiliary shielding cover is movably installed on the rear end of the shielding shell, and the auxiliary shielding cover can slide in the front direction relative to the shielding shell so that A first position and a second position are formed, and the auxiliary shielding cover can slide backward from the first position to the second position, an...

Problems solved by technology

[0005] However, if the rear end of the auxiliary shielding cover is directly welded to the circuit board to form a ground loop, this can shorten the grounding path of the current of the auxiliary shielding cover, but the auxiliary shielding cover cannot be movably installed on the rear end of the shielding shell. In other words, the first position for observing the soldering part cannot be formed, and the welding effect between the soldering part and the circuit board cannot be guaranteed, which in turn affects the signal transmission of the guaranteed terminal
