Electrical connection system with discrete wire interconnections
First Claim
1. An electrical connection apparatus comprising:
- a housing constructed and arranged with an upper portion and a bottom portion, a lower row of apertures and an upper row of apertures formed in said upper portion, wherein said apertures in said upper row are staggered with respect to said lower row of apertures, said adjacent apertures in the upper and the lower rows defining a first spacing therebetween, wherein said first spacings accommodate discrete electrical lead wire connections,said apertures in the lower and the upper rows connected by through holes to a row of apertures in the bottom portion of the housing, said apertures in said bottom portion defining a second spacing therebetween, wherein said first spacings are larger than said second spacingselectrical contacts arranged and constructed in and extending substantially through said housing from said apertures in said upper portion of said housing to said apertures in said bottom portion, wherein said electrical contacts are designed to accommodate said stagger, said electrical contacts having two ends, a first end having contact area for connecting to said discrete electrical lead wire, and a second end including a contact area for connecting to a male or female contact of a mating header.

Abstract
An electrical connector for joining individual, electrically conductive wires, to a printed circuit board. The wires may be individual solid or stranded types. A contact, provided within the connector housing, is arranged with a first end forming an area for attaching the wire and with a second end arranged usually with female contacts for connecting to a header on the printed circuit board. The wires are stripped of any insulation and mechanically attached to a contact in the connector. The wire is placed between a pressure plate and an area of the contact. A screw is rotated forcing the pressure plate and the contact area together physically squeezing the wire so that the wire is securely attached to the contact area to provide a good electrical contact. The second end of the contacts forms a female cantilevered contact arranged to mate with a header of a row of male pins soldered to the printed circuit board. The connector provides for offsetting the contact areas on adjacent contacts such that the spacing between the contacts accepting the wire are farther apart that the female contacts accepting the pins on the printed circuit board.

8. An electrical connection apparatus comprising:
-
a first housing, a second housing constructed and arranged to mate with said first housing forming a unified housing defining an upper portion and a bottom portion of said unified housing with an upper row of apertures, a lower row of apertures formed in said upper portion, and a row of apertures in said bottom portion arranged substantially in a single straight line row, and said apertures in said upper row staggered with respect to said apertures in said lower row, and wherein spacings of adjacent of said apertures in said upper portion are larger that spacings of said apertures in said bottom portion when measured center to center, wherein said larger spacings accommodate discrete wire connections, electrical contacts arranged and constructed in said apertures and extending substantially through said housing from said upper portion to said bottom portion, said electrical contacts having first ends arranged in apertures in the upper portion for making electrical connections to discrete wires and second ends arranged in the apertures in the bottom portion for making electrical connections to male or female pins of a mating header, and wherein each of said first ends includes a contact area arranged for receiving an electrically conductive wire, each of said contact areas having a through hole, and where each of said second ends includes dual beam female contacts, and extensions are constructed on said electrical contacts, said extensions arranged to mechanically engage said housing such that said contacts are secured to said housing, a screw with a threaded shaft arranged to extend through said hole, said screw having a slotted head suitable for receiving a screw driver, a pressure plate with a through hole, said pressure plate arranged between said contact area and the head of the screw, a nut threaded onto the shaft of the screw, said nut positioned with said pressure plate between the nut and the screw head, wherein, with an electrical wire placed between said contact area and said pressure plate, the wire is mechanically secured to said contact providing electrical conductivity between said wire and said contact area by tightening said screw.
