Abstract

The invention relates to the field of electric connectors, and particularly relates to a differential connector and a differential pair arrangement structure and a differential connector plug thereof. The differential connector plug comprises more than two signal modules which are laminated in a layered way. Every two signal modules are combined to form a signal module pair. The two signal modules of the same signal module pair form first and second signal modules. At least one differential pair of the first and second signal modules is first and second differential pairs. The differential pair contact members of the first and second differential pairs are first and second differential pair contact members. At least one of the two first differential pair contact members of at least one first differential pair and at least one of the two second differential pair contact members of at least one second differential pair have a point of intersection on the projection of the first and second signal modules in the layering direction. According to the differential connector plug, a shielding plate does not need to be additionally arranged so that the structure is simple, and the problems of low assembling efficiency and high processing cost caused by the complex structure of the present differential connector can be solved.
