Abstract
Abstract An apparatus for attaching slotted plate terminals or the like to individual wires such as the wires of a stator coil in an induction motor is disclosed. A rotatable arbor positions the stator in alignment with an insertion track and ram. A terminal is inserted by moving it along the tracks and into a cavity in an insulating housing mounted on the stator. A guide track along which an insertion ram moves a terminal also acts as a depth control for accurate positioning of the terminal.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
268 words
A method of attaching a contact terminal to an electrical conductor and positioning said terminal and said conductor in a terminal receiving cavity in an insulating housing, said terminal having conductor receiving means for establishing electrical contact with said conductor upon relative movement of said terminal towards the axis of said conductor, said method comprising the steps of: positioning said insulating housing with said cavity in alignment with an elongated insertion ram having a forward end and a rear end, said ram being movable towards and away from said cavity, positioning said conductor between said cavity and said forward end of said ram with said conductor spanning said cavity, positioning said terminal in a guide track between said ram and said conductor with said terminal in alignment with said cavity and with said conductor receiving means in alignment with said conductor, positioning a depth control device having first and second ends with said first end against an appropriate reference surface of said housing and between said housing and a ram stop fixed to said ram and located at said rearward end of said ram, and moving said ram along said guide track with said front end of said ram pushing said terminal into said cavity so that said conductor receiving means establishes electrical contact with said conductor, with further movement of said ram being prevented when said ram stop abuts said second end of said depth control device, whereby the final position of said conductor and said terminal with respect to said reference surface is determined by the relative length of said depth control devices and said ram.
Claim 2
Independent Claim
268 words
A method of attaching a contact terminal to an electrical conductor and positioning said terminal and said conductor in a terminal receiving cavity in an insulating housing, said terminal having conductor receiving means for establishing electrical contact with said conductor upon relative movement of said terminal towards the axis of said conductor, said method comprising the steps of: positioning said insulating housing with said cavity in alignment with an elongated insertion ram having a forward end and a rear end, said ram being movable towards and away from said cavity, positioning said conductor between said cavity and said forward end of said ram with said conductor spanning said cavity, positioning said terminal in a guide track between said ram and said conductor with said terminal in alignment with said cavity and with said conductor receiving means in alignment with said conductor, positioning a depth control device having first and second ends with said first end against an appropriate reference surface of said housing and between said housing and a ram stop fixed to said ram and located at said rearward end of said ram, and moving said ram along said guide track with said front end of said ram pushing said terminal into said cavity so that said conductor receiving means establishes electrical contact with said conductor, with further movement of said ram being prevented when said ram stop abuts said second end of said depth control device, whereby the final position of said conductor and said terminal with respect to said reference surface is determined by the relative length of said depth control devices and said ram.
Claim 3
Dependent Claim
43 words
A method as set forth in claim 1 wherein said conductor is initially laced into slots on the inner and outer sidewalls of said cavity, said inner slot being deeper than said outer slot so that said conductor initially obliquely spans said cavity.
Claim 4
Dependent Claim
56 words
A method as set forth in claim 2 wherein said conductor is cut along said outer sidewall before said terminal has been completely inserted into said cavity, and continued movement of said terminal into said cavity draws the cut end of said conductor into said cavity leaving no exposed conductor on the outside of said housing.
Claim 5
Dependent Claim
54 words
A method as set forth in claim 3 wherein the step of positioning said depth control device comprises the movement of said guide track so that the first end of said guide track abuts said reference surface and the opposite end of said guide track comprises said second end of said depth control device.
