Continuation of "DESCRIPTION OF PRIOR ART"
Finally, the prior art discloses a socket contact member which is capable of performing a wiping and a contact action. The latter principle is broadly referred to in U.S. Patent Number 4,062,610 of December 13, 1977 to Doty et al. As shown therein, two surfaces on the contact perform a wiping action when such surfaces come into contact with an inserted post.
It is apparent from the foregoing that the prior art fails to teach, or even suggest, an electrical connector possessing a dual-in-line contact feature which performs wiping and contact functions on an inserted pin, and a separable gas tight contact feature between the connector and a printed circuit board.
SUMMARY OF THE INVENTION
The invention pertains to an electrical connector including a receptacle body which is provided with a plurality of passageways extending from the top wall of the body through the bottom wall of the body. A dual-in-line contact member is disposed in each of the passageways. Each of the contact members has a first convex portion and a second convex portion facing toward the interior of the passageway in a pin facing direction, as well as a depending contact leg portion which projects through the bottom wall of the passageway and extends in a pin opposing direction.The receptacle is adapted to receive corresponding male pin contacts or posts of a plug member, such that a pin contact is inserted into each of the passageways of the receptacle. The first and second convex portions of the contact members provide first and second contact points for the inserted pin, and perform wiping functions with respect to the pin.
The receptacle is adapted to be separably mounted in electrical communication on a printed circuit board by means of the contact legs contacting a conductive strip on the printed circuit board. The contacts are adapted to be associated with through holes and/or solder pads provided on the printed circuit board. The contact utilize soft metals at high contact pressures so that, upon mating of the contacts, the metal is upset and the resultant joint prevents contamination gases from entering the contact area.
According to one aspect of the invention there is provided an electrical connector for electrical mating with a plug member having a plurality of male contact members and for electrical mounting on a printed circuit board, said electrical connector comprising a receptacle body, said body being defined by front and rear walls, a pair of end walls, a bottom wall and a top wall, a plurality of spaced passageways formed in said body and extending through said body from said top wall to said bottom wall, a single contact member received within each of said passageways, each of said contact members having a contact surface provided within its respective passageway, a depending gas tight contact portion provided on each of said contact members, said gas tight contact portions extending through said bottom wall of each passageway of said receptacle body and depending therefrom, said receptacle being adapted for electrical mating with said plug member by insertion of each of said male contact members into a respective one of said passageways, such that said contact surface electrically contacts said male contact member, said receptacle being adapted to be separably mounted on a printed circuit board by said contact portions contacting a conductive strip on said printed circuit board.
According to another aspect of the invention there is provided an electrical connector for electrical mating with a plug member having a plurality of male contact members and for electrical mounting on a printed circuit board, said electrical connector comprising an insulative receptacle body being defined by front and rear walls, a pair of end walls, a bottom wall and a top wall, a plurality of spaced passageways formed in said body and extending through said body from said top wall to said bottom wall, a shoulder member projecting from a portion of said body into each of said passageways, a single contact member received within each of said passageways, each of said contact members having a contact surface provided within its respective passageway, first and second contact points provided on said contact surface, a projection provided on each of said contact members for engaging said shoulder in said respective passageway for retaining said contact members in said passageways, a depending contact portion provided on each of said contact members, said contact portions extending through said bottom wall of each passageway of said receptacle body and depending therefrom, said receptacle being adapted for electrical mating with said plug member by insertion of each of said male contact members into a respective one of said passageways, much that said first and second contact points electrically contact and wipe said male contact member, said receptacle being adapted to be separably mounted on said printed circuit board by said contact portions contacting a conductive strip on said printed circuit board.
