Abstract
Abstract A female electrical connector element for connecting a wire lead to a male contact pin has a first end which is crimped to the wire lead and a second end in the form of a socket. The socket includes a cantilevered contact floor and a separate spring contact in opposed relation to the cantilevered contact floor. The male contact pin is inserted between the spring biased contact surface and the cantilevered contact floor to establish an electrical connection. In accordance with the method of fabricating the connector, the cantilevered contact floor is supported sequentially by a series of forming surfaces at a bight portion thereof while the contact floor is being bent through 180°. The side flanges of the female component are then folded over the contact for making an enclosure for defining the socket that retains the unitary spring contact.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
164 words
In a method for forming a female electrical terminal socket which is adapted to be affixed at one end to a wire lead and which has a socket at the other end for receiving a male contact pin urged into abutment with a portion of the socket by a contact spring, the improvement comprising the steps of forming the female socket from a unitary blank by: a) folding a pair of side flanges to extend substantially normal with respect to a base portion to form a channel; b) bending a cantilevered contact floor about a bight thereof into alignment with the channel so as to overlie the base portion; c) while bending the cantilevered contact floor, supporting the cantilevered contact floor continuously at the bight thereof to minimize the formation of cracks; and d) bending the side flanges so that free ends thereof overlie the cantilevered contact floor in spaced relation with respect thereto to form a space therebetween for receiving the contact spring.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
14 words
The improvement of claim 1, wherein the female electrical terminal is made of steel.
Claim 4
Dependent Claim
52 words
The improvement of claim 1, wherein the cantilevered contact floor is bent in a series of discrete steps from a first orientation in which the cantilevered contact floor extends in the same direction as the front base portion to the position in which the cantilevered contact floor overlies the front base portion.
Claim 5
Dependent Claim
39 words
The improvement of claim 3, wherein the discrete steps comprise a first discrete step of about 60°; a second discrete step of about 30°; a third discrete step of about 60°; and a fourth discrete step of about 30°.
Claim 6
Dependent Claim
14 words
The improvement of claim 4, wherein the female electrical terminal is made of steel.
Claim 7
Dependent Claim
51 words
The improvement of claim 3, wherein supporting the cantilevered contact floor while the floor is bent is accomplished by sequentially placing a series of supporting surfaces having progressively smaller angles with respect to the base portion of the blank between the cantilevered contact portion and the base portion of the blank.
Claim 8
Dependent Claim
39 words
The improvement of claim 6, wherein the discrete steps comprise a first discrete step of about 60°; a second discrete step of about 30°; a third discrete step of about 60°; and a fourth discrete step of about 30°.
Claim 9
Dependent Claim
14 words
The improvement of claim 7, wherein the female electrical terminal is made of steel.
