Abstract
Abstract The disclosure relates to a one-piece molded housing having terminals located therein in a cavity for making electrical contact with a printed circuit board and the like. At one end of the terminal are circuit engaging fingers for engaging a circuit on a printed circuit board, and at the other end is a hole for receiving a screw which secures the terminal end to the housing in conjunction with a nut; the screw receiving under its head the bared end of wire conductor. This end of the terminal may also have extending therefrom a tab portion for mating engagement with a receptacle terminated wire conductor.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
331 words
An edge connector for making electrical connection to a printed circuit board and the like comprising an elongated housing of electrically insulating material having a front face and a backface, an elongated cavity in said front face adapted to receive therein one edge of a printed circuit board, said front face including a plurality of recesses, a plurality of apertures in said housing, each aperture communicating with said backface and one each of said recesses, said cavity having a rear wall, a first sidewall and a second sidewall spaced from each other and normal to said rear wall, said first sidewall having raised ribs on its inside surface offset from said passageways, said raised ribs limiting the width of said cavity thereby limiting lateral movement of said printed circuit board upon insertion into said cavity, a plurality of passageways in said housing in communication between said rear wall and said backface, a contact positioned within at least one of said passageways, one end of said contact including circuit engaging means extending from one end of said passageway into said cavity for engaging circuitry on said printed circuit board, said circuit engaging means comprising at least one curved finger cantilevered to said contact, the free end of said finger engaging said inside surface of said first sidewall with an intermediate portion of said finger extending above the height of said raised ribs so as to make electrical contact with said circuitry on said printed circuit board, and the other end of said contact including wire conductor termination means for making electrical contact with a wire conductor, said termination means including a hole, and screw means cooperating therewith for securing said wiRe conductor to said other end of said contact, and wherein said screw means comprises a screw passing through said hole in said contact and through one of said apertures and extending into a respective one of said recesses, and a nut received in said recess and being threaded onto said screw.
Claim 2
Dependent Claim

An edge connector for making electrical connection to a printed circuit board and the like comprising an elongated housing of electrically insulating material having a front face and a backface, an elongated cavity in said front face adapted to receive therein one edge of a printed circuit board, said front face including a plurality of recesses, a plurality of apertures in said housing, each aperture communicating with said backface and one each of said recesses, said cavity having a rear wall, a first sidewall and a second sidewall spaced from each other and normal to said rear wall, said first sidewall having raised ribs on its inside surface offset from said passageways, said raised ribs limiting the width of said cavity thereby limiting lateral movement of said printed circuit board upon insertion into said cavity, a plurality of passageways in said housing in communication between said rear wall and said backface, a contact positioned within at least one of said passageways, one end of said contact including circuit engaging means extending from one end of said passageway into said cavity for engaging circuitry on said printed circuit board, said circuit engaging means comprising at least one curved finger cantilevered to said contact, the free end of said finger engaging said inside surface of said first sidewall with an intermediate portion of said finger extending above the height of said raised ribs so as to make electrical contact with said circuitry on said printed circuit board, and the other end of said contact including wire conductor termination means for making electrical contact with a wire conductor, said termination means including a hole, and screw means cooperating therewith for securing said wiRe conductor to said other end of said contact, and wherein said screw means comprises a screw passing through said hole in said contact and through one of said apertures and extending into a respective one of said recesses, and a nut received in said recess and being threaded onto said screw.
Claim 3
Dependent Claim
69 words
An edge connector as set forth in claim 1 wherein each said recess has a first wall common with said cavity, second and third spaced parallel walls adjoining said first wall and normal thereto, and a fourth wall joining said second and third walls, spaced from and parallel to said first wall, and wherein said second and third walls act as supports for said second sidewall of said cavity.
Claim 4
Dependent Claim
53 words
An edge connector as set forth in claim 2 wherein said contact is positioned in said passageway by insertion into said passageway, said passageway having shoulder means therein, and said contact having stop means protruding therefrom for engagement with said shoulder means thereby allowing for proper positioning of said contact within said passageway.
Claim 5
Dependent Claim
34 words
An edge connector as set forth in claim 3 wherein said other end of said contact additionally includes a terminal portion integral therewith, said terminal portion adapted to mate with a terminated wire conductor.
Claim 6
Dependent Claim
37 words
An edge connector as set forth in claim 3 including a key element, and wherein said first and second sidewalls of said cavity have located on their front face edges means to selectively receive said key element.
Claim 7
Dependent Claim
27 words
An edge connector as set forth in claim 3 wherein each said passageway contains a contact and each cooperating recess and aperture contains a nut and screw.
