Abstract
Abstract A connector socket of the integrated wire termination system (IWTS) type adapted to receive a ''''standard'''' terminal (connector) pin inserted therein by a split-sleeve tool. The socket includes an integral retainer formed thereon for engaging the annular shoulder of the terminal pin to lock it in electrically conducting relation therewithin. This integral retainer is a split spring sleeve that has a notch at its forward end on the side opposite the split providing a catch. The socket has an aperture in one side. This split and notched sleeve is placed around the aperture section, and the part back of the notch is formed partly through such aperture to form a catch for engaging the annular shoulder of the terminal pin. Insertion of a split-sleeve release tool from the rear allows release of the terminal pin for disconnection.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
188 words
An integrated wire termination system having an integrally formed retainer comprising: an electrically conducting connector socket having a bore extending thereinto from the rear end thereof adapted to receive a shouldered terminal pin; an aperture in the side of said connector socket; and a spring-biased catch extending through said aperture partly into said bore for engaging the annular shoulder of the terminal pin pressed into said bore and to bias the terminal pin against the internal wall of said connector socket for good electrical contact therewith; said catch comprising a split sleeve retainer of resilient material surrounding said socket and held thereon and having a notch at its forward end on the side opposite the split and overlying said aperture; and a portion of said split sleeve retainer back of said notch overlying said aperture being formed through said aperture to cause the edge of said notch to serve as a catch for the terminal pin shoulder and to provide an inclined inner surface that may be engaged by a release tool to bias said catch clear of said shoulder for release of said terminal pin for disconnection.
Claim 2
Dependent Claim
188 words
An integrated wire termination system having an integrally formed retainer comprising: an electrically conducting connector socket having a bore extending thereinto from the rear end thereof adapted to receive a shouldered terminal pin; an aperture in the side of said connector socket; and a spring-biased catch extending through said aperture partly into said bore for engaging the annular shoulder of the terminal pin pressed into said bore and to bias the terminal pin against the internal wall of said connector socket for good electrical contact therewith; said catch comprising a split sleeve retainer of resilient material surrounding said socket and held thereon and having a notch at its forward end on the side opposite the split and overlying said aperture; and a portion of said split sleeve retainer back of said notch overlying said aperture being formed through said aperture to cause the edge of said notch to serve as a catch for the terminal pin shoulder and to provide an inclined inner surface that may be engaged by a release tool to bias said catch clear of said shoulder for release of said terminal pin for disconnection.
Claim 3
Dependent Claim
188 words
An integrated wire termination system having an integrally formed retainer comprising: an electrically conducting connector socket having a bore extending thereinto from the rear end thereof adapted to receive a shouldered terminal pin; an aperture in the side of said connector socket; and a spring-biased catch extending through said aperture partly into said bore for engaging the annular shoulder of the terminal pin pressed into said bore and to bias the terminal pin against the internal wall of said connector socket for good electrical contact therewith; said catch comprising a split sleeve retainer of resilient material surrounding said socket and held thereon and having a notch at its forward end on the side opposite the split and overlying said aperture; and a portion of said split sleeve retainer back of said notch overlying said aperture being formed through said aperture to cause the edge of said notch to serve as a catch for the terminal pin shoulder and to provide an inclined inner surface that may be engaged by a release tool to bias said catch clear of said shoulder for release of said terminal pin for disconnection.
Claim 4
Dependent Claim
188 words
An integrated wire termination system having an integrally formed retainer comprising: an electrically conducting connector socket having a bore extending thereinto from the rear end thereof adapted to receive a shouldered terminal pin; an aperture in the side of said connector socket; and a spring-biased catch extending through said aperture partly into said bore for engaging the annular shoulder of the terminal pin pressed into said bore and to bias the terminal pin against the internal wall of said connector socket for good electrical contact therewith; said catch comprising a split sleeve retainer of resilient material surrounding said socket and held thereon and having a notch at its forward end on the side opposite the split and overlying said aperture; and a portion of said split sleeve retainer back of said notch overlying said aperture being formed through said aperture to cause the edge of said notch to serve as a catch for the terminal pin shoulder and to provide an inclined inner surface that may be engaged by a release tool to bias said catch clear of said shoulder for release of said terminal pin for disconnection.
Claim 5
Dependent Claim
85 words
The invention defined in claim 1, wherein: said connector socket comprises a generally cylindrical member having said bore extending from the open rear end almost to the forward end thereof; and the section within said split sleeve retainer being of reduced external diameter affording an enlarged collar at the rear end thereof and a shoulder at the forward end thereof for holdIng said split sleeve retainer in place; the resilience of said split sleeve retainer affording spreading thereof sufficiently to assemble it over said collar.
Claim 6
Dependent Claim
34 words
The invention defined in claim 1, wherein: the portion of said split sleeve retainer formed through said aperture is provided with a configuration affording large angle long arcuate distance engagement with the terminal pin.
