Abstract

Abstract A contact socket for electrical devices including a base member made from insulating material and having an opening in the form of an elongated window opening to one side of the base member and leading to an enlarged diameter chamber opening to the opposite side of the base member. The chamber terminates into a reduced diameter neck portion leading along a portion of the window for receiving a narrowed neck of a contact member. The contact member has a widened portion longer than the elongated window and has a shoulder engaging the top of the base member, a narrower portion fitting in the elongated window and a connecting portion leading from the narrower portion. A pair of wings extend radially from the connecting portion beneath the narrower portion. The enlarged diameter chamber has oppositely inclined top surfaces converging to an apex. When the contact member is inserted in the socket through the window with the shoulder abutting the top of the base, the wings will lie along the apex of the chamber and, as twisted, will engage the inclined surfaces of the top wall of the chamber and be cammed thereby to tighten the contact member in the window and bring the shoulder in firm engagement with the top of the base. An insulating compound can be inserted into the chamber to seal the window and the solder side of the contact member.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 156 words
In a contact socket for electrical devices, a base made from insulating material having top and bottom surfaces and an elongated window leading through the top surface thereof and having communication with the bottom surface thereof, a main chamber leading from said window and opening to the bottom surface of the base and having at least one arcuately inclined top camming surface, a twisting chamber extending upwardly of said inclined camming surface and recessed in side walls of said window, a flat contact part having a shoulder engageable with the top of said base, a reduced width portion fitting within said window, a reduced neck depending from said reduced width portion and having oppositely extending wings defining the lower margins thereof and having engagement with said inclined camming surface of said main chamber and bringing said shoulder into tight engagement with the top surface of said base upon twisting movement of said wings about said neck.
Claim 2
Dependent Claim 156 words
In a contact socket for electrical devices, a base made from insulating material having top and bottom surfaces and an elongated window leading through the top surface thereof and having communication with the bottom surface thereof, a main chamber leading from said window and opening to the bottom surface of the base and having at least one arcuately inclined top camming surface, a twisting chamber extending upwardly of said inclined camming surface and recessed in side walls of said window, a flat contact part having a shoulder engageable with the top of said base, a reduced width portion fitting within said window, a reduced neck depending from said reduced width portion and having oppositely extending wings defining the lower margins thereof and having engagement with said inclined camming surface of said main chamber and bringing said shoulder into tight engagement with the top surface of said base upon twisting movement of said wings about said neck.
Claim 3
Dependent Claim 95 words
The socket device of claim 1, wherein the top of said main chamber forms said inclined camming surface and is arcuately inclined upwardly in opposite directions toward an apex in alignment with the longitudinal center of said window, accommodating the top surfaces of said wings to lie along said apex when inserting the contact part through said window and having camming engagement with the top surfaces of said wIngs to cam said shoulder of said contact part into tight engagement with the top surface of said base, upon twisting of said wings about said neck.
Claim 4
Dependent Claim 41 words
The socket device of claim 2, in which a connector member depends from said wings to serve as a solder connector, and wherein the window has parallel side walls spaced apart a distance substantially equal to the thickness of said connector.
Claim 5
Dependent Claim 53 words
The socket device of claim 3, in which the twisting chamber comprises aligned recesses in said parallel side walls of said window having partial cylindrical wall portions, with a top wall closing the twisting chamber to the top surface except through the window, and with said window forming a generally cylindrical twisting chamber.
Claim 6
Dependent Claim 22 words
The socket device of claim 3, in which the downwardly opening camming main chamber is filled with an insulating and sealing compound.
