Abstract

A card edge connector includes an insulative housing, a number of contacts retained in the insulative housing and an ejector retained the insulative housing to lock an electronic card. The insulative housing includes a central slot for receiving the electronic card and two end portions located on opposite sides of the central slot respectively. The card edge connector also includes a metal member located on the end portion of the insulative for electrically connecting to the metal member. Thus, The card edge connector having a higher electrical function.

First claim

We claim:

1. A card edge connector, comprising:
an elongated insulative housing having an central slot for insertion of a daughter card and a pair of end portions located on opposite sides of the central slot respectively;
a plurality of terminals retained in the housing and protruding into the central slot for mating with the daughter card; and
at least one lock mechanism pivoted at one end portion for locking with the daughter card; wherein
the card edge connector further comprise a metal member located on the end portion of the insulative housing for electrically connecting to the daughter card; wherein
the metal member defines a contacting arm for electrically connecting to the daughter card and a mounting portion adapted to be mounted on a printed circuit board; wherein
the metal member includes a contacting member and a mounting member, one side of the contacting member connects to the daughter card and another side connects to the mounting member, and said mounting member is mounted on the printed circuit board and retained in the end portion; wherein
a receiving room is formed on a top region of the end portion to receive the lock mechanism, the housing defines a retaining wall around the receiving room for abutting against the lock mechanism, and the contacting member is associatively moveable with the lock mechanism and clamped between said lock mechanism and said retaining wall in a longitudinal direction along which said central slot extends; wherein
said contacting member defines a body section, a horizontal section perpendicular to the to the body section, a clamping section perpendicular to the horizontal section which extends on a reverse direction of the body section and an elastic section obliquely bending towards a same side of the body section, the clamping section is clamped between said lock mechanism and said retaining wall, said elastic section abuts against on a upper side of the mounting member; wherein
the lock mechanism defines an internal surface faced to the retaining wall, a pair of protecting walls are formed on opposite sides of the internal surface, said protecting walls are located on outer sides of the contacting arms respectively; wherein
said internal surface defines a pair of holes located between said two protecting walls, a pair of locking portions are symmetrically formed on the internal surface and located under said holes, said body section defines a pair of retaining arms extending towards to the internal surface and said retaining arm is retained in the hole, said body section defines a pair of openings located under retaining arms, said openings are retained between two locking portions, a vertical groove is formed at a central of the internal surface and an abutting portion is formed in the vertical groove, said abutting portion is located under the locking portion, the clamping section is retained between the abutting portion and the retaining wall.

2. The card edge connector as claimed in claim 1 , wherein said retaining arm is located under the contacting section.
