Anti-interference card edge connector

Abstract

The invention discloses an anti-interference card edge connector which comprises an insulating body, an upper-row terminal integrated piece and a lower-row terminal integrated piece, the upper-row terminal integrated piece comprises an upper-row terminal base body and a plurality of upper-row terminals, and main body parts of the upper-row terminals are fixed on the upper-row terminal base body; the lower-row terminal integrated piece comprises a lower-row terminal base body and a plurality of lower-row terminals, the main body parts of the lower-row terminals are fixed on the lower-row terminal base body, and the upper-row terminal base body and the lower-row terminal base body are respectively fixed in the upper-row terminal accommodating groove and the lower-row terminal accommodating groove at the two sides of the insulating body; the upper-row terminal contact arms of the upper-row terminals and the lower-row terminal contact arms of the lower-row terminals are inserted into the upper-row terminal accommodating grooves and the lower-row terminal accommodating grooves of the insulating body in a one-to-one correspondence mode, and the upper-row terminal welding parts of the upper-row terminals and the lower-row terminal welding parts of the lower-row terminals are located on the same welding plane outside the insulating body. According to the invention, the blocking of the holding part on the terminal to a high-frequency signal is avoided, the attenuation degree of the signal is effectively reduced, and the high-frequency performance of a product is greatly improved.

Description

technical field [0001] The invention relates to a connector, in particular to an anti-interference card edge connector. Background technique [0002] The card edge connector generally includes an insulating body, an upper row of terminals, a lower row of terminals, a lock and a grounding piece. The insulating body is formed with a central slot for the insertion of an electronic card and an upper row of terminals for the insertion of the upper row of terminals and the lower row of terminals. The terminal receiving slots of the upper row and the lower row of terminal receiving grooves, the contact arms of the upper row of terminals and the lower row of terminals and the contact parts of the lower row of terminals respectively enter the central slot through the upper row of terminal receiving grooves and the lower row of terminal receiving grooves, so as to realize the connection with the electronic card. The upper golden fingers are in contact with each other, and both the upp...

Problems solved by technology

[0003] With the continuous iteration of the communication network, high frequency has become an inevitable trend in the electronic communication industry. The higher the frequency, the shorter the wavelength. The above-mentioned upper row of terminals and lower row of terminals are equipped with a holding part, and the holding part will be sensitive to high frequency signals. Blocking, resulting in faster signal attenuation, resulting in serious signal loss, so the traditional terminal structure design is difficult to meet the requirements of high-frequency communication
