Abstract

An electrical connector (10) is disclosed having a one piece housing (12), a plurality of cavities (18,20,22,24) in the housing, arranged in two vertical stacks (14,16) of four cavities each, and a contact (26,28,30,32) in each cavity. The cavities in each stack are separated by thin walls (48,50,52) of the housing. Each of the contacts has a contact end (68) for mating with a mating connector, and a tail (78) that exits from the contact at a right angle to the mounting surface (36) of the connector. Some of the contacts (28,30,32) have support members (94,96,98,100,102,104) that extend from the contact to engage the floor (53) of the cavity while the upper surface of the contact is in engagement with the ceiling (51) of the cavity. There is a bearing structure established from the tails (78) through the support members and the thin walls (48,50,52) to the top surface (34) of the connector housing. This permits installation of the connector (10) to a circuit board (112) by applying an insertion force directly to the top surface of the housing.

Dependent claims

An electrical connector for mounting to a mounting surface of a circuit board and being electrically interconnected to circuitry on said circuit board, said connector comprising:

(a) an insulating housing having a top surface and a bottom surface defining a plane substantially parallel to said top surface, said bottom surface adapted to be mounted to said mounting surface of said circuit board, said housing having a plurality of spaced cavities formed therein stacked vertically between said top and bottom surfaces and separated by relatively thin walls so that each cavity has an upper wall and a lower wall;
(b) a plurality of contacts, one of which is in each respective said cavity, each said contact having a body, a contact portion extending from an end of said body, and a transition member extending from an opposite end of said body at right angles to said plane and joined to said body at a bend, a portion of said body at said bend being in engagement with said upper wall of its respective cavity,
wherein some of said contacts, have a support means extending from its body into engagement with said lower wall of its respective cavity for providing a vertical bearing structure between said upper and lower walls,
said support means arranged so that a longitudinal axis of each said transition member extends through a respective said lower wall, support means, and upper wall of each cavity vertically above thereby defining a vertical bearing structure between said top surface and each said transition member for inserting said transition members into engagement with said circuit board.

An electrical connector assembly adapted for mounting to a major surface of a circuit board having transition member receiving apertures formed therein, comprising:

(a) an insulating housing having a plurality of vertically stacked cavities arranged between said top and bottom surfaces, said bottom surface defining a plane that is coplanar with said major surface of said circuit board;
(b) a plurality of contacts, one of which is in each respective cavity, each said contact having a body, a contact portion extending from an end of said body, and a transition member extending from an opposite end of said body at right angles to said plane and joined to said body at a bend, a portion of said transition member adapted to be an interference fit with said transition member receiving holes, a portion of said body at said bend being in engagement with an upper wall of its respective cavity,
wherein some of said contacts, have a support means extending from its body into engagement with a lower wall, opposite said upper wall, of its respective cavity, for providing an insertion force transmitting structure between said upper and lower walls, said contacts being adapted for said mounting by inserting said portions of said transition members in said transition member receiving holes through the application of a downward insertion force to said top surface of said housing for transmitting said insertion force through said housing and said support means to said contact transition members through the engagement of said support means and said lower walls,
whereby, upon positioning said connector so that said portions of said transition members are partially inserted into their respective transition member receiving holes in said circuit board, and upon applying an insertion force to said top surface, said insertion force is transmitted through said housing and through said support means of respective contacts to said transition members and said portions of said transition members will be driven into their respective transition member receiving holes.
