High frequency connector

Abstract

The invention discloses a high-frequency connector. The high-frequency connector comprises an insulating body, a contact terminal, a grounding lug and a shielding case. The insulating body comprises a base and a tongue plate, the front end surface of the tongue plate is recessed backwards to form an inserting slot, and the contact terminal is exposed inside the inserting slot; the grounding lug is arranged corresponding to the front part of the inserting slot and on the front side of the contact terminal; the ground lug comprises a base plate part, a plurality of first spring pieces, a plurality of second spring pieces and a plurality contact protrusions, wherein the first spring pieces, the second spring pieces and the contact protrusions are integrally formed from the base plate part through stamping; every first spring piece is provided with a first elastic butting part, which is protruded towards the inserting slot and exposed inside the inserting slot,, and the first spring piece is provided with a second yielding through slot communicating the upper surface and the lower surface of the base plate part; every second spring piece is suspended inside the corresponding second yielding through slot; the contact protrusions are formed between every two neighboring two first spring pieces; the shielding case wraps the outer surface of the tongue plate; the second spring pieces and the contact protrusions are pressed by the shielding case and electrically abut against the inner wall of the shielding case to effectively disperse stress of the grounding lug during insertion and extraction and further to avoid deformation of the first spring pieces due to overlarge stress.

Description

technical field [0001] The invention relates to the technology in the field of connectors, in particular to a high-frequency connector. Background technique [0002] The current connector has gradually developed into an ultra-thin type, and undoubtedly the distance between the upper and lower rows of contact terminals has also been further reduced, resulting in stronger signal interference between the contact terminals, which is not conducive to the transmission of high-frequency signals; The way is to set the grounding piece to form a better shielding effect when the plug and socket are connected to each other and improve the anti-interference ability. However, the shrapnel on the traditional grounding piece is likely to be caused by large stress during the multiple insertion and extraction process. The deformation of the shrapnel affects the contact stability of the ground sheet, and the shielding effect is difficult to be guaranteed, which affects the transmission stabili...

[0002] The current connector has gradually developed into an ultra-thin type, and undoubtedly the distance between the upper and lower rows of contact terminals has also been further reduced, resulting in stronger signal interference between the contact terminals, which is not conducive to the transmission of high-frequency signals; The way is to set the grounding piece to form a better shielding effect when the plug and socket are connected to each other and improve the anti-interference ability. However, the shrapnel on the traditional grounding piece is likely to be caused by large stress during the multiple insertion and extraction process. The shrapnel is deformed, so it affects the contact stability of the ground sheet, and the shielding effect is difficult to guarantee, which affects the transmission stability of high-frequency signals
