Abstract
Abstract An electrical shunt includes a U-shape contact having a unitary body molded directly in a housing into which pin contacts may be inserted for connection to and via the shunt. A method of making an electrical shunt formed of an electrically conductive contact having plural contacting portions for connection with respective external members inserted to connection therewith and an electrically non-conductive housing includes molding electrically non-conductive material directly to at least part of such contact to form such housing, whereby such housing and contact form an integral structure, including forming relatively open chamber areas within the housing for exposure therein of such contacting portions, and forming an opening in such housing for insertion therein of respective external members for electrical connection with respective contacting portions.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
222 words
A method of making an electrical device including an electrically conductive member supported in a molded body of electrically non-conductive material, the molded body including therein an open chamber in which a compliant portion of the conductive member is movable and exposed for electrically connecting with an external member inserted into the chamber through an open end of the chamber, the conductive member also having a base portion to which the body is molded to anchor the conductive member in the body, the method comprising the steps of placing the conductive member in a mold, molding the body using the mold while using a mold core within the cavity of the mold to form the chamber in the body, and removing the molded body from the mold with the conductive member supported therein, said placing step including inserting the compliant portion of the conductive member into a cavity space in the mold core with the conductive member extending through an open end of the cavity space to locate the base portion of the conductive member outside the cavity space, and said molding step including closing the mold with a part thereof cooperating with the mold core and conductive member to close off the open end of the cavity space to prevent the material of the body from flowing into the cavity space.
Claim 2
Independent Claim
222 words
A method of making an electrical device including an electrically conductive member supported in a molded body of electrically non-conductive material, the molded body including therein an open chamber in which a compliant portion of the conductive member is movable and exposed for electrically connecting with an external member inserted into the chamber through an open end of the chamber, the conductive member also having a base portion to which the body is molded to anchor the conductive member in the body, the method comprising the steps of placing the conductive member in a mold, molding the body using the mold while using a mold core within the cavity of the mold to form the chamber in the body, and removing the molded body from the mold with the conductive member supported therein, said placing step including inserting the compliant portion of the conductive member into a cavity space in the mold core with the conductive member extending through an open end of the cavity space to locate the base portion of the conductive member outside the cavity space, and said molding step including closing the mold with a part thereof cooperating with the mold core and conductive member to close off the open end of the cavity space to prevent the material of the body from flowing into the cavity space.
Claim 3
Dependent Claim
43 words
The method of claim 1, wherein said closing step includes using a pair of core elements projecting into the mold cavity respectively to engage opposite edge surfaces of the conductive member to provide a shut-off at the open end of said core cavity.
Claim 4
Dependent Claim
35 words
The method of claim 1, wherein said closing step includes engaging respective sides of the conductive member against adjacent side walls of the cavity space to close off the open end of the cavity space.
Claim 5
Dependent Claim
32 words
The method of claim 1, wherein said molding step includes using conductive members with beveled corners engageable by the core elements to urge an off-center conductive member to a relatively centered position.
Claim 6
Dependent Claim
44 words
The method of claim 1, wherein said molding step includes molding the body with stop portions between the core elements and mold core, such stop portions being operative in the electrical device to limit maximum insertion penetration of respective external members into the body.
Claim 7
Dependent Claim
56 words
The method of claim 1, wherein said molding step includes using the core elements to form openings to the side of the body opposite the open end of the chamber, the openings being operative in the electrical device for permitting passage therethrough of electrical members electrically connecting with the compliant connecting portions of the conductive member.
Claim 8
Dependent Claim
37 words
The method of claim 1, wherein said placing step includes engaging an end of the conductive member against a bottom surface of the cavity space properly to locate the conductive member with respect to the mold core.
Claim 9
Dependent Claim
14 words
The method of claim 1, wherein the mold core is generally O-shape in cross-section.
Claim 10
Dependent Claim
35 words
The method of claim 1, wherein said closing step includes engaging respective sides of the conductive member against adjacent side walls of the cavity space to close off the open end of the cavity space.
Claim 11
Dependent Claim
37 words
The method of claim 1, wherein said placing step includes engaging an end of the conductive member against a bottom surface of the cavity space properly to locate the conductive member with respect to the mold core.
Claim 12
Dependent Claim
51 words
The method of claim 1, wherein said molding step includes molding the body with at least one stop portion adjacent the end of the mold core, said stop portion being operative in the electrical device to limit maximum insertion penetration of the external member into the body of the electrical device.
Claim 13
Independent Claim
244 words
A method of making an electrical device including an electrically conductive member supported in a molded body of electrically non-conductive material, the molded body including therein an open chamber in which a compliant portion of the conductive member is movable and exposed for electrically connecting with an external member inserted into the chamber through an open end of the chamber, the conductive member also having a base portion to which the body is molded to anchor the conductive member in the body, the method comprising the steps of placing the conductive member in a mold, molding the body using the mold while using a mold core within the cavity of the mold to form the chamber in the body, and removing the molded body from the mold with the conductive member supported therein, said placing step including inserting the compliant portion of the conductive member into a cavity space in the mold core with the conductive member extending through an open end of the cavity space to locate the base portion of the conductive member outside the cavity space, said molding step including closing the mold and closing off the open end of the cavity space to prevent the material of the body from flowing into the cavity space, and said closing off step including closely positioning respective sides of the conductive member adjacent side walls of the cavity space to block flow of the material of the body therebetween into the cavity space.
