Abstract
Abstract A connector socket of the integrated wire termination system (IWTS) type adapted to receive any one of a plurality of different types of ''''standard'''' terminal (connector) pins inserted therein by a split sleeve tool. The socket includes a spring-biased pawl for engaging the annular shoulder on the terminal pin to lock it therein. A split sleeve spring biases the pawl against the periphery of the annular shoulder for large area of electrical contact between the socket and the pin. The socket is deep enough to receive terminal pins having different lengths of tips. A switch contact or terminal rivet structure may be provided on the front end. Insertion of a tool from the rear allows release of the terminal pin.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
280 words
An integrated wire termination system comprising: an electrically conducting connector member having a bore extending thereinto from one end thereof adapted to receive an arcuate-surface-shouldered terminal pin that is secured to the end of a wire with the portion of the pin on one side of its shoulder being of reduced size to provide space therearound within said bore for insertion of a split sleeve release tool; an aperture in the side of said connector member; an arcuate catch in said aperture; a split sleeve spring surrounding said connector member to bias said catch into said aperture; a linear cam surface on said catch extending forwardly at an inward angle whereby said catch is moved outwardly against the force of said spring by the terminal pin shoulder when the terminal pin is inserted into said bore; said catch having a lateral shoulder that snaps behind the terminal pin shoulder by force of said spring when the terminal pin has been fully inserted to lock the terminal pin within said bore in good electrical contact with said connector member to prevent removal of the terminal pin by pulling on the wire, and release of the terminal pin requiring insertion of the release tool around the reduced portion thereof within said bore to bias said catch free of the terminal pin shoulder and withdrawal of the terminal pin and tool together; and said bore in said connector member being large enough to receive the split sleeve release tool around the reduced portion of the terminal pin to engage said cam surface and cam said catch outwardly clear of the terminal pin shoulder to release the terminal pin for withdrawal from said bore.
Claim 2
Dependent Claim
280 words
An integrated wire termination system comprising: an electrically conducting connector member having a bore extending thereinto from one end thereof adapted to receive an arcuate-surface-shouldered terminal pin that is secured to the end of a wire with the portion of the pin on one side of its shoulder being of reduced size to provide space therearound within said bore for insertion of a split sleeve release tool; an aperture in the side of said connector member; an arcuate catch in said aperture; a split sleeve spring surrounding said connector member to bias said catch into said aperture; a linear cam surface on said catch extending forwardly at an inward angle whereby said catch is moved outwardly against the force of said spring by the terminal pin shoulder when the terminal pin is inserted into said bore; said catch having a lateral shoulder that snaps behind the terminal pin shoulder by force of said spring when the terminal pin has been fully inserted to lock the terminal pin within said bore in good electrical contact with said connector member to prevent removal of the terminal pin by pulling on the wire, and release of the terminal pin requiring insertion of the release tool around the reduced portion thereof within said bore to bias said catch free of the terminal pin shoulder and withdrawal of the terminal pin and tool together; and said bore in said connector member being large enough to receive the split sleeve release tool around the reduced portion of the terminal pin to engage said cam surface and cam said catch outwardly clear of the terminal pin shoulder to release the terminal pin for withdrawal from said bore.
Claim 3
Dependent Claim
61 words
The invention defined in claim 1, wherein: said connector member and said bore therein are long enough to receive any one of a plurality of different ''''standard'''' terminal pins that are alike from the rear end that is crimped onto the end of a wire up to and including the shoulder but differ in the length or diameter of front tip.
Claim 4
Dependent Claim
34 words
The invention defined in claim 1, wherein said connector member comprises: a constricting shoulder within said bore serving as a stop for the terminal pin shoulder to fix its locked position within said bore.
Claim 5
Dependent Claim
36 words
The invention defined in claim 1, wherein said connector member comprises: a front closed end; and a contact secured on said front closed end thereof adapting it for use as a stationary contact for a switch.
Claim 6
Dependent Claim
29 words
The invention defined in claim 1, wherein said spring and connector member comprises: registering means for orienting the spring so that its split is diametrically opposite to said catch.
Claim 7
Dependent Claim
44 words
The invention defined in claim 1, wherein said catch also comprises: a complementary arcuate surface that is biased by said spring against the arcuate surface of the terminal pin shoulder to provide a high pressure electrical contact between said catch and the terminal pin.
Claim 8
Dependent Claim
52 words
The invention defined in claim 6 wherein: said bore has an arcuate surface complementary to the arcuate surface of said terminal pin shoulder; and said spring acts through said catch to bias the arcuate surface on the other side of the terminal pin shoulder against the complementary arcuate surface of said bore.
Claim 9
Dependent Claim
159 words
An integrated wire termination system comprising: an electrically conducting connector member having a bore extending thereinto from one end thereof adapted to receive a shouldered terminal pin, said bore having a shoulder therein forming a stop for the shoulder on the terminal pin; an aperture in the side of said connector member; a pawl in said aperture; a split sleeve spring around said connector member biasing said pawl through said aperture into said bore; and said pawl having an inNer surface configuration within said bore comprising; a cam surface effective when acted upon by the terminal pin shoulder when the terminal pin is inserted in the bore for moving said pawl outwardly against the force of said spring; and a catch that snaps behind the terminal pin shoulder by force of said spring when the terminal pin has been inserted against said stop to lock the terminal pin within said bore in good electrical contact with said connector member.
Claim 10
Dependent Claim
159 words
An integrated wire termination system comprising: an electrically conducting connector member having a bore extending thereinto from one end thereof adapted to receive a shouldered terminal pin, said bore having a shoulder therein forming a stop for the shoulder on the terminal pin; an aperture in the side of said connector member; a pawl in said aperture; a split sleeve spring around said connector member biasing said pawl through said aperture into said bore; and said pawl having an inNer surface configuration within said bore comprising; a cam surface effective when acted upon by the terminal pin shoulder when the terminal pin is inserted in the bore for moving said pawl outwardly against the force of said spring; and a catch that snaps behind the terminal pin shoulder by force of said spring when the terminal pin has been inserted against said stop to lock the terminal pin within said bore in good electrical contact with said connector member.
Claim 11
Dependent Claim
50 words
The invention defined in claim 8, wherein said inner configuration of said pawl also comprises: a reentrant cam surface extending from the first mentioned cam surface to said pawl catch insuring that the terminal pin shoulder clears said pawl catch upon removal of the terminal pin with a retraction tool.
Claim 12
Dependent Claim
34 words
The invention defined in claim 8, wherein said integrated wire termination system also comprises: cooperating sides on said pawl and said aperture that prevent said pawl from falling through said aperture into said bore.
