Abstract
Abstract A terminal is provided for use in interconnecting the magnet wire of a field coil of an electric motor to another circuit element such as a lead wire. The terminal is insulatively mounted on the field core, preferably before winding the coils. The terminal includes a channel part adapted to be crimped to the magnet wire and a socket part adapted to receive the circuit element.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
164 words
A terminal to facilitate the connection of an electrical conductor wire thereto, comprising: an insulating block having a hole therein; and a one-piece electrically conductive terminal connector having offset first and second portions joined by a joining portion; said first portion having a generally tubular form and being inserted into said hole and frictionally held therein; said second portion being located outside said block and being a generally U-shaped channel to receive said conductor wire, and having collapsible side walls and a base portion, said base portion being generally tangent to said first portion and all imaginery lines passing longitudinally along said channel parallel to said base being located outside said first portion, and said side walls having opposed notches therein near the extremity of said second portion to form a main segment of sufficient length to securely hold said conductor wire and a severable segment whereby said conductor wire may first be temporarily gripped by collapsing said side walls of said severable segment.
Claim 2
Dependent Claim
164 words
A terminal to facilitate the connection of an electrical conductor wire thereto, comprising: an insulating block having a hole therein; and a one-piece electrically conductive terminal connector having offset first and second portions joined by a joining portion; said first portion having a generally tubular form and being inserted into said hole and frictionally held therein; said second portion being located outside said block and being a generally U-shaped channel to receive said conductor wire, and having collapsible side walls and a base portion, said base portion being generally tangent to said first portion and all imaginery lines passing longitudinally along said channel parallel to said base being located outside said first portion, and said side walls having opposed notches therein near the extremity of said second portion to form a main segment of sufficient length to securely hold said conductor wire and a severable segment whereby said conductor wire may first be temporarily gripped by collapsing said side walls of said severable segment.
Claim 3
Dependent Claim
57 words
A terminal as claimed in claim 1 wherein said first portion includes a tang extending diagonally across said first portion and joined to one side of said first portion, said tang including a curved portion extending outside of said first portion for increasing the effective force exerted by said tang against an element inserted in said socket.
Claim 4
Dependent Claim
41 words
The terminal as claimed in claim 1 further including a conductor wire lying in said second portion between said side walls with said conductor wire having an end being at least partially enveloped by the side walls of the severable segment.
Claim 5
Independent Claim
131 words
A method of securing an electrical conductor to a one-Piece electrical terminal connector having a U-shaped channel to receive said conductor and having a terminal contact portion, said channel having a main portion and a severable portion, said method comprising the steps of: positioning said conductor in said channel so that a portion of the conductor to be severed is positioned in the severable portion of the connector; crimping the walls of said severable portion causing them to collapse against the conductor thereby to temporarily secure the conductor in the channel, crimping the main portion of the channel to secure the conductor therein and to complete the electrical connection between the conductor and the connector; and severing the severable portion of the connector and the portion of the conductor held therein.
Claim 6
Independent Claim
131 words
A method of securing an electrical conductor to a one-Piece electrical terminal connector having a U-shaped channel to receive said conductor and having a terminal contact portion, said channel having a main portion and a severable portion, said method comprising the steps of: positioning said conductor in said channel so that a portion of the conductor to be severed is positioned in the severable portion of the connector; crimping the walls of said severable portion causing them to collapse against the conductor thereby to temporarily secure the conductor in the channel, crimping the main portion of the channel to secure the conductor therein and to complete the electrical connection between the conductor and the connector; and severing the severable portion of the connector and the portion of the conductor held therein.
