Abstract
The invention discloses a high-speed transmission card edge connector which is provided with an insulation body, a plurality of upper conductive terminals and a plurality of lower conductive terminals. A plurality of upper terminal grooves and a plurality of lower terminal grooves are arranged on the insulation body, the upper conductive terminals are fixedly held on the upper terminal grooves, and the lower conductive terminals are fixedly held on the lower terminal grooves. Two lateral walls which form the upper conductive terminals are different in widths, two lateral walls which form the lower conductive terminals are different in widths, the narrow portions of the grooves can effectively prevent the terminals from swinging and overturning, the wide portions of the grooves lead large gap zones to be formed between adjacent terminals, and insulation media between the adjacent terminals change from the existing single even media to uneven media. A large number of gaps exist and dielectric coefficient of the insulation media is different from that of the air in the gaps so that the total media attribute of adjacent terminals change to lead the corresponding capacitance effect to change, the purpose of improving characteristic impedance on the condition of ensuring that the terminals do not swing or deflect is achieved, and high-speed digital transmission requirements are met.
