Abstract

A connector is disclosed which draws static charges to ground. The connector comprises a male plug having a generally non-yielding terminal attached to a projection extending from its mating surface and a female receptacle having at least one terminal mounting cavity in a mating surface and a flexible female terminal in the cavity. The female receptacle has a metal cover on its outer surface which is connected to ground. The male terminal and projection is dimensioned so as to permit insertion through the aperture in the cover and into a slot in the female housing. The flexible female terminal remains contained within the slot of the female housing and below the cover prior to making contact with the male terminal.

Claims

1. A static charge removal connector comprising:

a male plug (21) including a male housing (22) having a base, a terminal mount (23), and at least one male terminal (24) fixed to the terminal mount (23);

a female receptacle (1) comprising a female housing (2) having at least one terminal mounting cavity (3) and a flexible female terminal (4) in the cavity, said female housing (2) having a metal cover (11) integrally connected to ground bars (15) and applied to a top surface (10) of said female housing (2) said cover (11) having apertures (41) through which said terminal mount (23) with said male terminal (24) can be inserted;

said terminal mount (23) projecting from a floor (29) of the male housing (22) of the male plug (21), and physically dimensioned so as to permit insertion through the aperture (41) in said cover (11) and into a slot (12) in the female housing (2), said male terminal (24) being fixed to said terminal mount (23) with a contact section (26) of said male terminal (24) laid on the top of said terminal mount (23), thus permitting the contact section (26) of said male terminal (24) to come to contact the contact section (6) of said flexible female terminal (4) when said male plug (21) is mated with said female receptacle (1); and

said female terminal (4) which is yieldingly deformable remains contained within slot (12) of said female housing (2) prior to making contact with the male terminal (24),

said female terminal having a base section (7) with two ends mounted within said female housing (2), one end integrally connected to a solder tail section (9) adapted to be connected to a trace on a printed circuit board and the other end integrally connected to a flexible bent section (5) which supports one end of a flat contact section (6) with the other end of the flat contact section (6) supported by a flexible arm (8),

whereby the upward force provided by the flat contact section (6) against the male terminal (24) due to the support at both ends of the flat contact section by the flexible bent section (5) and the flexible arm (8) is generally equal across the entire length of the contact section (6).

2. A static charge removal connector according to claim 1 wherein said metal cover (11) comprises front, rear and opposite side sections (13) and (14) to cover corresponding front, rear and opposite side surfaces of said female housing (2), said opposite side sections (14) having ground pieces (15) integrally connected.

3. A static charge removal connector according to claim 2 wherein a plurality of female terminals (4) are contained within slots (12) arranged at regular intervals in staggered relation in said female housing (2) and wherein a plurality of male terminals (24) are arranged in said male housing (22) at the same regular intervals in staggered relation as the intervals of the female terminals.
