Abstract
Abstract A method of manufacturing electrical contact sockets by stamping and forming sheet metal comprises steps of blanking a strip to form two pairs of arms extending in opposite directions on each side of the strip. The arms are twisted and bent about their own longitudinal axes and are then bent adjacent to the center of the strip to define a socket.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
150 words
A method of making contact sockets which are adapted to receive cylindrical contact pins having a diameter d, said method comprising the steps of, BLANKING AN ELONGATED STRIP OF SHEET METAL TO FORM ASSOCIATED PAIRS OF CONTACT ARMS EXTENDING FROM THE SIDES OF SAID STRIP, THE TWO ARMS OF EACH PAIR BEING SPACED-APART BY A DISTANCE SUBSTANTIALLY EQUAL TO THE DIAMETER D OF SAID PIN, SAID PAIRS BEING ALIGNED ON OPPOSITE SIDES OF SAID STRIP, TWISTING SAID ARMS ABOUT THEIR LONGITUDINAL AXES AT A LOCATION INTERMEDIATE THEIR ENDS TO ORIENT SURFACE PORTIONS OF SAID ARMS ON CIRCULAR LOCI HAVING A DIAMETER SUBSTANTIALLY EQUAL TO SAID DIAMETER D, THE TWO ARMS OF EACH PAIR ON THE SAME OF SAID STRIP BEING ORIENTED IN OPPOSITE DIRECTIONS WHEREBY, THE FOUR ARMS OF TWO ALIGNED PAIRS OF ARMS EXTENDING FROM OPPOSITE SIDES OF SAID STRIP CONSTITUTE ARMS FOR A SOCKET INTEGRAL WITH SAID STRIP.
Claim 2
Independent Claim
150 words
A method of making contact sockets which are adapted to receive cylindrical contact pins having a diameter d, said method comprising the steps of, BLANKING AN ELONGATED STRIP OF SHEET METAL TO FORM ASSOCIATED PAIRS OF CONTACT ARMS EXTENDING FROM THE SIDES OF SAID STRIP, THE TWO ARMS OF EACH PAIR BEING SPACED-APART BY A DISTANCE SUBSTANTIALLY EQUAL TO THE DIAMETER D OF SAID PIN, SAID PAIRS BEING ALIGNED ON OPPOSITE SIDES OF SAID STRIP, TWISTING SAID ARMS ABOUT THEIR LONGITUDINAL AXES AT A LOCATION INTERMEDIATE THEIR ENDS TO ORIENT SURFACE PORTIONS OF SAID ARMS ON CIRCULAR LOCI HAVING A DIAMETER SUBSTANTIALLY EQUAL TO SAID DIAMETER D, THE TWO ARMS OF EACH PAIR ON THE SAME OF SAID STRIP BEING ORIENTED IN OPPOSITE DIRECTIONS WHEREBY, THE FOUR ARMS OF TWO ALIGNED PAIRS OF ARMS EXTENDING FROM OPPOSITE SIDES OF SAID STRIP CONSTITUTE ARMS FOR A SOCKET INTEGRAL WITH SAID STRIP.
Claim 3
Dependent Claim
88 words
A method as set forth in claim 1 wherein said strip, after blanking, has a width substantially equal to d and including the steps of bending said arms in a common direction substantially normally of the plane of said strip whereby the four arms of two aligned pairs of arms on opposite sides of said strip define a contact socket with portions of said strip between said four arms defining the inner end of said socket, said method producing a continuous strip of sockets on parallel spaced-apart axes.
Claim 4
Dependent Claim
146 words
A method as set forth in claim 1 including the step of bending the base portions of said arms in a common first direction until said base portions of said arms extend transversely of the plane of said strip and bending intermediate portions of said arms in a common second direction which is transverse to said first direction and substantially parallel to the plane of said strip whereby, intermediate and end portions of said arms extend substantially parallel to the plane of said strip and away from said sides of said strip, the two arms of each pair of arms being twisted towards each other whereby, two of said strips and be placed against each other and secured to each other to provide a strip having contact sockets extending from each side thereof with the axes of said sockets being between the plane of said strips.
Claim 5
Dependent Claim
166 words
The method set forth in claim 1 wherein said strip, after blanking, has a width which is substantially equal to, and slightly greater than, 2 d and including the step of bending said arms in a common direction until they extend substantially normally of the plane of said strip, the two arms of each pair of arms being twisted in opposite directions towards each other and inwardly with respect to said strip, and including the further steps of blanking a second elongated strip to form arms as hereinabove set forth in claim 1, twisting the arms of associated pairs of arms on each side of said strip outwardly with respect to said second strip and towards each other, positioning said second strip centrally on said first strip with each pair of arms of said second strip opposed to a pair of arms of said first strip and securing said strips to each other thereby to produce a composite terminal strip having two rows of side-by-side terminals.
