Abstract
Abstract A connector including a rotation symmetric contact pin mountably received within a bore in a housing. The housing includes a stop chamber adapted to lockingly engage resilient stop springs tangentially attached to the contact pin when the pin is inserted into the bore such that the resilient stop springs extend from the contact pin into the stop chamber. Rotation of the contact pin retracts the stop springs into openings in the contact pin and permits withdrawal of the contact pin from the bore.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
155 words
A connector assembly comprising: a connector housing; a bore in said connector housing; a stop chamber in said bore; a contact pin rotatably received by said bore for removingly mating with said stop chamber, said contact pin having a contact end extending from said connector housing when said contact pin is received by said bore, a terminal receiving end and at least one aperture between said contact end and said terminal receiving end; and resilient locking tab means attached, at one end, to said contact pin proximate said aperture for maintaining said contact pin in either a lock state or a release state with respect to said connector housing, said lock state comprising the engagement of said locking tab means with said stop chamber when said pin is inserted into said bore, said release state comprising the retraction of said locking tab means into said aperture when said connector pin is rotated within said bore.
Claim 2
Dependent Claim
155 words
A connector assembly comprising: a connector housing; a bore in said connector housing; a stop chamber in said bore; a contact pin rotatably received by said bore for removingly mating with said stop chamber, said contact pin having a contact end extending from said connector housing when said contact pin is received by said bore, a terminal receiving end and at least one aperture between said contact end and said terminal receiving end; and resilient locking tab means attached, at one end, to said contact pin proximate said aperture for maintaining said contact pin in either a lock state or a release state with respect to said connector housing, said lock state comprising the engagement of said locking tab means with said stop chamber when said pin is inserted into said bore, said release state comprising the retraction of said locking tab means into said aperture when said connector pin is rotated within said bore.
Claim 3
Dependent Claim
18 words
The connector assembly of claim 1 wherein said resilient locking tab extends tangentially away from said contact pin.
Claim 4
Dependent Claim
36 words
The connector assembly of claim 2 wherein two resilient locking tabs are provided on diametrically opposite sides of said contact pin and are synchrenously extended on retracted upper rotation of said contact pin within said bore.
Claim 5
Dependent Claim
12 words
The connector assembly of claim 1 wherein the contact pin is cylindrical.
Claim 6
Dependent Claim
18 words
The connector assembly of claim 1 wherein the resilient locking tab is rounded off at its unattached end.
Claim 7
Dependent Claim
15 words
The connector assembly of claim 1 wherein the resilient locking tab is of spring steel.
Claim 8
Dependent Claim
20 words
The connector assembly of claim 1 wherein the resilient locking tab is welded onto the contact pin at said aperture.
Claim 9
Dependent Claim
24 words
The connector assembly of claim 3 wherein the housing includes four stop chambers dispersed at equal angular distances on the circumference of said bore.
Claim 10
Dependent Claim
45 words
The connector assembly of claim 3 wherein the portion of said contact pin proximate said terminal receiving end has a greater diameter than the portion proximate said contact end and wherein said resilient locking tabs are located on said enlarged portion of said contact pin.
Claim 11
Dependent Claim
30 words
The connector assembly according to claim 9 wherein each of said locking tabs has a width which corresponds approximately to the diameter of the enlarged portion of said contact pin.
Claim 12
Dependent Claim
26 words
The connector assembly of claim 4 wherein a plurality of resilient locking tabs are respectively arranged in spaced relation along the axis of said contact pin.
