Card edge connector assembly and positioning method of the same

摘要

A card edge connector assembly comprising a first card edge connector comprising a first insulative housing, a pair of first latching arms disposed on opposite ends of the first insulative housing and a plurality of first conductive terminals retained in the first insulative housing; a second card edge connector including a second insulative housing, a pair of second latching arms located on the opposite ends of the second insulative housing and a plurality of second conductive terminals retained in the second insulative housing. The first and second terminals define pin-shaped solder portions respectively, wherein the first and second insulative housings define protruding portions and recessed portions mutually engaged with each other when the first and second insulative housings are disposed in a head to head arrangement. It can shorten distance between the first and second card edge connectors, which is conducive to miniaturization of connector assembly.

主权项

1. A card edge connector assembly adapted to being mounted on a mother board, comprising:
a first card edge connector comprising a first insulative housing with a first central slot, a pair of first latching arms disposed on opposite ends of the first insulative housing and a plurality of first conductive terminals retained in the first insulative housing; a second card edge connector including a second insulative housing with a second central slot, a pair of second latching arms located on the opposite ends of the second insulative housing and a plurality of second conductive terminals retained in the second insulative housing; the first and second conductive terminals defining pin-shaped solder portions respectively, wherein a rear wall of the first and second insulative housings respectively define protruding portions extended outwardly from the rear wall and recessed portions mutually engaged with each other when the first and second insulative housings are disposed in a head to head arrangement and the first and second latching arms extend far away from each other; wherein the first insulative housing defines a first key and the second insulative housing defines a second key, the first and second keys are aligned with each other, wherein the first conductive terminals are divided into upper and lower rows and accommodated in the first insulative housing, and the second conductive terminals are also divided into upper and lower rows and accommodated in the second insulative housing, corresponding upper and lower rows of terminals are offset from each other, wherein a fixed member is located between the first card edge connector and the second card edge connector and make them bounded to each other; and wherein the first and second insulative housing are same in external structures.
