Abstract

A lamp socket assembly which includes a plastic socket body having a tubular portion adapted to receive a socket insert along a first axis and having a connector portion integral therewith which receives the wire terminals along a second axis which is substantially perpendicular to the first axis.

Claims

1. A lamp socket assembly including a plastic socket body having a tubular portion for receiving a socket insert along a first axis and having a connector portion for receiving a plurality of female wire terminals along a second axis which is substantially perpendicular to the first axis, said socket insert having a front end provided with a feed terminal and a ground terminal for electrical engagement with the contacts of a lamp bulb, each of said terminals having an integral blade member projecting outwardly from the rear end of said socket insert along axes substantially parallel to the longitudinal center axis of said socket insert, and said connector portion having spaced cavities formed therein for receiving said wire terminals along axes parallel to said second axis and for positioning said wire terminals in the socket body so when said socket insert is axially inserted into said tubular portion along said first axis, said blade member of each of said feed terminal and said ground contact mate with said wire terminals for providing electrical current to said lamp bulb.

2. A lamp socket assembly including a plastic socket body having a tubular portion for receiving a socket insert along a first axis and having a connector portion for receiving a plurality of female wire terminals along a second axis which is substantially perpendicular to the first axis, said socket insert being cylindrical in configuration and having a front end provided with a pair of feed terminals and a ground terminal for electrical engagement with the contacts of a lamp bulb, each of said feed terminals and said ground terminal having an integral blade member projecting outwardly from the rear end of said socket insert along spaced axes each of which is substantially parallel to the longitudinal center axis of said socket insert, and said connector portion having three laterally spaced and generally square cavities formed therein for receiving said wire terminals along axes parallel to said second axis and for positioning the latter in the socket body so when said socket insert is axially inserted into said tubular portion along said first axis, said blade member of each of said feed terminals and said ground contact mate with said wire terminals for providing electrical current to said lamp bulb.

3. A lamp socket assembly including a plastic socket body having a tubular portion formed with a circular opening for receiving a socket insert along a first axis and having a connector portion for receiving a plurality of female wire terminals along a second axis which is substantially perpendicular to the first axis, said socket insert being cylindrical in configuration and having a front end provided with a pair of feed terminals and a ground terminal for electrical engagement with the contacts of a snap-in wedge type lamp bulb, each of said feed terminals and said ground terminal having an integral blade member projecting outwardly from the rear end of said socket insert along spaced axes each of which is substantially parallel to the longitudinal center axis of said socket insert, and said connector portion having three laterally spaced and generally square cavities formed therein for receiving said wire terminals along axes parallel to said second axis and for positioning the latter in the socket body so when said socket insert is axially inserted into said tubular portion along said first axis, said blade member of each of said feed terminals and said ground contact mate with said wire terminals for providing electrical current to said lamp bulb, and said socket insert and said tubular portion having cooperating means for locking said socket insert in said opening of said tubular portion when said socket insert is inserted into said tubular portion.

4. The lamp socket assembly set forth in claim 3 wherein each of said cavities in said connector portion is generally circular at its entrance end and generally square in cross section in the area defined by said circular opening in the tubular portion of the socket body.

5. The lamp socket assembly set forth in claim 4 wherein each of said cavities in the area of said tubular portion is defined by a pair of side walls, an end wall, a front wall, and a back wall.

6. The lamp socket assembly set forth in claim 5 wherein the front wall faces the open end of the circular opening in the tubular member and is formed with a slot for allowing said blade member to extend into the receptacle portion of the wire terminal located in the associated cavity.

7. The lamp socket assembly set forth in claim 3 wherein said cooperating means for locking said socket insert in said tubular portion includes a pair of spring arms integrally formed with the socket insert and a pair of diametrically opposed openings formed in the tubular portion.

8. The lamp socket assembly set forth in claim 3 wherein said circular opening in said tubular portion and the outer peripheral portion of the socket insert are formed with cooperating means for properly indexing said socket insert during the insertion of the latter into the tubular portion.

9. The lamp socket assembly set forth in claim 8 wherein said cooperating means is a rib formed on the inside diameter of said tubular portion and a slot formed in the outer peripheral portion of the socket insert.
