Abstract
Abstract An electrical connector ( 1 ) comprises an upper housing ( 2 ), a bottom housing ( 3 ) and a terminal module ( 4 ). The upper housing and the bottom housing together define a space and a mating port ( 20 ) positioned near the space. The terminal module has a base ( 40 ), a tongue ( 41 ) extending in the mating port from the base in a mating direction, and a plurality of signal terminals ( 7, 8 ) and grounding terminals ( 5, 6 ) therein. The signal terminals are disposed opposite sides of the tongue in pairs. A square hole ( 418 ) is formed in the tongue and aligned with every two opposite signal terminals.
