Buckling structure of electric connector

Abstract

The invention relates to a buckling structure of an electric connector, which comprises an insulating body, a shielding shell, a cover plate and two locking fasteners, two sides of the cover plate are respectively provided with a turning piece with a top and a downward-bent inserting and fixing part, the inserting and fixing part of each turning piece is provided with a buckling hole, the two locking fasteners are provided with U-shaped pieces for inserting the inserting and fixing part on the two sides of the cover plate, the outer side wall of each U-shaped piece obliquely extends towards an inner clamping groove to be provided with a positioning buckle used for being buckled to the buckle hole of the corresponding inserting and fixing part, and the two locking fasteners fixed to the two sides of the cover plate are each provided with a positioning protruding block on the opposite inner side face. The two locking fasteners on the two sides of the cover plate slide and buckle the two positioning bumps in the two positioning holes of the shielding shell in the vertical direction to be locked and positioned, and the two locking fasteners on the two sides of the cover plate push in the horizontal direction to slide the two positioning bumps out of the two positioning holes of the shielding shell to be unlocked and released; and the cover plate moves upwards to be separated from the insulating body and the shielding shell, so that the locking fastener is tightly buckled on the electric connector and is not easy to loosen.

Description

technical field [0001] The invention relates to a snap-fit ​​structure of an electrical connector, in particular to the problem that a latch is tightly snap-fitted on an electrical connector and is not easy to loosen. At the same time, the locking and unlocking of the latch are simple electrical connections device structure. Background technique [0002] With the vigorous development of modern electronic communication technology, the transmission rate of electronic signals is increasing day by day. The electrical connectors used in computers and electronic products must be suitable for transmitting high-frequency and high-speed signals, and are installed between the liquid crystal display and the system motherboard. The high-frequency signal transmission system often uses a low voltage differential signal (Low Voltage Differential Signal, LVDS) connector, which uses extremely low voltage amplitude to transmit data at high speed, and has the advantages of low power consumptio...

AI Technical Summary

Problems solved by technology

[0003]The main structure of the existing low-voltage differential signal connector includes an insulating body, a signal terminal and a shielding shell. The insulating body has a plug-in space, and the signal terminal Inserted into the insulating body, and the engaging part on the signal terminal is fixed inside the insulating body, the butt joint part of the signal terminal extends into the insertion space, and the welding part of the signal terminal extends out of the insulating body; the shielding shell covers On the insulating body, the shielding shell is fixedly connected to the insulating body, and the shielding shell has an inwardly bent contact spring, which can shield the electromagnetic wave noise by connecting the contact spring to the preset plug connector, and connect a The long sheet-shaped locking part is installed at the locking points on both sides of the insulating body, and the cable is installed at a preset position by a twisting and buckling method, and is electrically connected to the signal terminal. Low-voltage differential signal connectors often have insufficient joint strength in the vertical direction in use, and the locking parts are prone to loosening, which needs to be improved by those engaged in this industry
