Abstract
Abstract A female contact having a shell that encloses a collet that has an opening in a first end of the collet and that has a second end that is configured so that, when a male pin is inserted through the first end of the collet, it pushes on the second end of the collet either directly or indirectly through some mechanism such as a spring. This female contact has a small diameter that makes it particularly suitable for certain applications and in some embodiments extends outward from the shell to facilitate inserting a male pin into the collet.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
161 words
A female contact comprising: an electrically conductive shell having an opening in a first end, the first end of said shell lying in a plane; a collet inserted through said opening in the first end of said shell; said collet having a first end that includes an opening through which a male pin is to be inserted; said collet also having a second end with means connected to the second end that is configured such that the inserted male pin engages the means, whereby, when this female contact is mated to a male contact, the collet is pressed into said shell by force transmitted by said means and applied to the second end of said collet; a portion of said collet at the first end of the collet being configured such that when the female contact is mated with the male contact having the male pin, the portion of the collet makes electrical contact with the shell substantially in the plane.
Claim 2
Dependent Claim
161 words
A female contact comprising: an electrically conductive shell having an opening in a first end, the first end of said shell lying in a plane; a collet inserted through said opening in the first end of said shell; said collet having a first end that includes an opening through which a male pin is to be inserted; said collet also having a second end with means connected to the second end that is configured such that the inserted male pin engages the means, whereby, when this female contact is mated to a male contact, the collet is pressed into said shell by force transmitted by said means and applied to the second end of said collet; a portion of said collet at the first end of the collet being configured such that when the female contact is mated with the male contact having the male pin, the portion of the collet makes electrical contact with the shell substantially in the plane.
Claim 3
Dependent Claim
48 words
A female contact as in claim 1 wherein said second end of the collet includes an elastic member, in contact with the second end, against which said male pin presses when said male and female contacts are mated, thereby pressing against said second end via said elastic member.
Claim 4
Dependent Claim
39 words
A female contact as in claim 1 wherein said collet further comprises a projection which extends into a slot in said shell to retain the collet within the shell while allowing the collet to slide longitudinally within the shell.
Claim 5
Dependent Claim
54 words
A female contact as in claim 1 further comprising means for extending said collet outward through said opening in the shell when the female contact is not in contact with a male contact and for allowing the collet to be pressed into said shell when the female contact is mated with a male contact.
Claim 6
Dependent Claim
31 words
A female contact as in claim 4 wherein said means for extending comprises an elastic member connected between the second end of the collet and a second end of the shell.
Claim 7
Dependent Claim
50 words
A female contact as in claim 1 wherein, at the first end of the collet, the portion of the collet flares outward such that when the female contact is mated with the male contact, this flaring portion of the collet makes electrical contact with the shell substantially in the plane.
Claim 8
Dependent Claim
37 words
A female contact as in claim 6 wherein the first end of the shell includes a sloping wall and wherein said electrical contact between the collet and the shell occurs on this sloping wall of the shell.
Claim 9
Dependent Claim
86 words
A female contact as in claim 7 wherein said shell and collet are coaxial with a common axis A, wherein said flaring portion of the collet has an inner surface that forms an angle α with axis A, wherein the sloping wall at the first end of the shell forms an angle β with axis A and wherein angle α is greater than angle β so that the point of contact between the flaring portion of the collet and the shell is substantially in the plane.
Claim 10
Dependent Claim
28 words
A female contact as in claim 8 wherein, as the female contact is mated with a male contact, the collet forms a wiping electrical contact with the shell.
Claim 11
Dependent Claim
34 words
A female contact as in claim 8 wherein, when the female contact is mated with a male contact, the first end of the shell is substantially coplanar with the first end of the collet.
Claim 12
Dependent Claim
51 words
A female contact as in claim 8 that is mated to a male contact having a male pin having a sufficient diameter and length that, as the male pin is being inserted into the open end of the collet, the collet presses inward against the male pin forming a wiping contact.
Claim 13
Dependent Claim
36 words
A female contact as in claim 1 wherein a portion of the collet between its first and second ends is slotted to provide an axially flexible element for accommodating a range of lengths of male pins.
Claim 14
Dependent Claim
39 words
A female contact as in claim 12 wherein said collet further comprises a projection which extends into a slot in said shell to retain the collet within the shell while allowing the collet to slide longitudinally within the shell.
