Title: Electrical connector
Claims: I claim: 1. An electrical connector comprising: a housing and a contact member; said housing made of plastic material having formable and deflectable character; said housing having a box like body and a cover; a hinge structure integral with and interconnecting said body and said cover; said box like body having an open side and a closed side; said cover adapted hingedly to be positioned to enclose said open side of said body; said box like body having wall portions integral with said closed sides; said wall portions having edges disposed at said open side; said edges adapted to be contiguous with said cover portion; said contact member being made of flat resilient sheet metal and having a middle portion provided with generally flat opposite sides and a plurality of generally flat contact portions having opposite sides and being integral with said middle portion, said contact member positioned in said body by a pair of first projections extending from said closed side of said box like body; said pair of first projections holding said middle portion of said contact member in fixed position adjacent said closed side of said body and thereby preventing substantial movement of said contact member in directions longitudinally of said contact portions; second projections integral with said cover and disposed between said pair of first projections extending from the closed side of said body; said second projections holding said middle portion of said contact member adjacent to said closed side of said body; said contact portions having said opposite sides disposed generally at right angles to said opposite sides of said middle portion; said body having wall portions substantially parallel with said opposite sides of said flat contact portion; said contact portions each having a conductor contacting and wedging edge; a conductor engaging wall portion of said body closely adjacent each wedging edge of each of said contact portions; said body having a conductor receiving opening in some of said wall portions adjacent each of said wedging edges of said contact portions; whereby electrical conductors may be inserted through conductor receiving openings and forced between respective wall portions and said wedging edge portions of said conductor portions and whereby resilient character of said contact portions allows said wedging edge portions to be forced into an angular wedging relation to the respective conductors thereby causing wedging entrapment thereof in said body. 2. The invention as defined in claim 1 wherein said first projections comprise a pair of spaced apart projections integral with said closed side of said body and straddle said middle portion of said contact member. 3. The invention as defined in claim 2 wherein said second projections which are integral with said cover are provided with opposite surfaces disposed in closely spaced proximity to respective wall portions of said body; said contact portions of said contact member being held between said opposite surfaces and said respective wall portions of said body. 4. The invention as defined in claim 1 wherein said contact member at said wedging edge portions of said contact portions, being adapted wedgingly to engage and entrap an electrical conductor whereby said integral middle portion of said conductor member conductively couples all of such conductors. 5. The invention as defined in claim 1 wherein said body is provided with converging surfaces in said side walls defining said conductor receiving openings; said coverging surfaces converging inwardly toward the interior of said box shaped body thereby defining inwardly converging openings; said converging surfaces thus adapted to wedgingly hold a conventional insulator sheath of an electrical conductor extending through a respective conductor receiving opening. 6. The invention as defined in claim 1 wherein said cover is fused to said body. 7. The invention as defined in claim 1 wherein said body at said open side thereof is provided with ledge portions; said cover being provided with respective and cooperative interlocking ledge portions whereby said cover is adapted to be snapped closed over the open side of said body. 8. The invention as defined in claim 1 wherein a rivet extends through said cover and said closed side of said body thereby holding said cover contiguous with the open side of said body and enclosing the same. 9. The invention as defined in claim 1 wherein a metal clip straddles said body and said cover thereby holding said cover in contiguous position with the open side of said body and enclosing the same. 10. The invention as defined in claim 1 wherein said cover at the open side of said body is cemented thereto, thereby holding said cover in closed position relative to the open side of the said body. 11. An electrical connector comprising a housing and a contact member; said housing made of plastic material having formable and deflectable character; said housing having a box like body and a cover; a hinge structure integral with interconnecting said body and cover; said box like body having an open side and a closed side; said cover adapted hingedly to be positioned to enclose said open side of said body; said box like body having wall portions integral with said closed side; said wall portions having edges disposed at said open side; said edges adapted to be contiguously engaged with said cover portion; said contact member being made of flat resilient sheet metal and being generally H-shaped with a pair of generally parallel flat and elongated contact portions each having opposite ends and a generally flat cross bar portion integral with said contact portions and disposed between said opposite ends of said contact portions; said resilient metal contact member positioned in said body by first projections extending from said closed side of said body which hold said cross bar of said contact member in fixed position adjacent said closed side and thereby preventing substantial movement of said contact member in directions longitudinally of said contact portions and second projections which are integral with said cover having opposite surfaces disposed in closely spaced proximity to respective wall portions of said body; said contact portions of said contact member being held between respective ones of said surfaces and respective wall portions; said flat cross bar portion having opposite sides; said flat contact portions having opposite sides disposed at substantially right angles to said opposite sides of said cross bar portion; said sides of said contact portions being disposed adjacent opposite ones of said wall portions of said box like body; said opposite ends of said contact portions being disposed substantially at right angles to other ones of said wall portions of said body and in close proximity thereto; said opposite ones of said wall portions of said body having conductor receiving openings therein; said openings located near said opposite ends of said contact portions whereby electrical conductors may be inserted through said conductor receiving openings and forced between said opposite ends of said contact portions and respective other ones of said wall portions of said body; and whereby the resilient character of said contact portions allows said opposite ends thereof to be deflected and forced into an angular wedging relation to the respective conductors thereby causing wedging entrapment thereof in said body. 12. The invention as defined in claim 11 wherein said first projections comprise a pair of projections integral with said closed side of said body and straddle said cross bar portion of said contact member. 13. The invention as defined in claim 11 wherein said contact member at both opposite ends of both of said contact portions each being adapted to wedgingly entrap an electrical conductor whereby said integral cross bar portions conductively couples all of said conductors. 14. The invention as defined in claim 11 wherein converging surfaces of said side wall portions define said conductor receiving openings; said converging surfaces converging inwardly toward the interior of said box like body and said converging surfaces thus adapted to wedgingly hold a conventional insulation sheet of an electrical conductor.
