Abstract
Abstract Method and apparatus for simplifying the process of connecting external lead wires to windings in a dynamoelectric machine is disclosed wherein there is provided a plurality of pairs of intermeshable electric connectors and at least one annular insulating member having one connector of each pair affixed thereto and external lead wires connected to certain ones of the affixed connectors with the other connector of each pair being connected to selected winding leads. The other connector of each pair may also be affixed to another annular insulating member so that, when the two annular members are in a juxtaposed position, respective pairs are aligned, and additional conductors may be provided on either insulating member for interconnecting windings as desired. The annular members may also function to surround the winding end turns at one end of the machine stator to confine and protect those end turns.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
127 words
In a dynamoelectric machine stator having windings disposed in slots of the stator core and extending therefrom at opposite stator ends to form end turns, a winding connector for attaching external lead wires to the leads of the windings comprising: a plurality of pairs of intermeshable electrical connectors; an annular insulating member having one connector of each pair affixed thereto and external lead wires connected to certain ones of the affixed connectors, the other connector of each pair being connected to selected winding leads; and at least one generally U-shaped insulating member straddling end turn portions for supporting the other connector of each pair in a respective location to allow simultaneous interengagement of connector pairs when the annular insulating member is juxtaposed with the U-shaped insulating member.
Claim 2
Dependent Claim
127 words
In a dynamoelectric machine stator having windings disposed in slots of the stator core and extending therefrom at opposite stator ends to form end turns, a winding connector for attaching external lead wires to the leads of the windings comprising: a plurality of pairs of intermeshable electrical connectors; an annular insulating member having one connector of each pair affixed thereto and external lead wires connected to certain ones of the affixed connectors, the other connector of each pair being connected to selected winding leads; and at least one generally U-shaped insulating member straddling end turn portions for supporting the other connector of each pair in a respective location to allow simultaneous interengagement of connector pairs when the annular insulating member is juxtaposed with the U-shaped insulating member.
Claim 3
Dependent Claim
20 words
The combination of claim 1 further comprising another annular insulating member having the other of each connector pair affixed thereto.
Claim 4
Dependent Claim
34 words
The combination of claim 2 wherein portions of the annular insulating members are adapted to at least partially surround the end turns at one stator end to confine and protect the surrounded end turns.
Claim 5
Dependent Claim
27 words
The combination of claim 1 wherein there are more winding leads than external lead wires, the annular member having conductor means thereon for interconnecting selected connector pairs.
Claim 6
Dependent Claim
112 words
In a dynamoelectric machine, structure for effecting the interconnection of stator winding leads with external lead wires comprising: a plurality of electrical connectors each crimped to a respective stator winding lead; a multiple lead wire harness having a common external connector at one end thereof and an individual terminal on each lead wire at the other end thereof; and means coupling the electrical connectors to respective lead wires at the ends thereof remote from the external connector including a pair of annular insulating members relatively movable into a juxtaposed position to simultaneously form electrical connections to all of the electrical connectors to electrically couple the electrical connectors to their respective lead wires.
Claim 7
Dependent Claim
112 words
In a dynamoelectric machine, structure for effecting the interconnection of stator winding leads with external lead wires comprising: a plurality of electrical connectors each crimped to a respective stator winding lead; a multiple lead wire harness having a common external connector at one end thereof and an individual terminal on each lead wire at the other end thereof; and means coupling the electrical connectors to respective lead wires at the ends thereof remote from the external connector including a pair of annular insulating members relatively movable into a juxtaposed position to simultaneously form electrical connections to all of the electrical connectors to electrically couple the electrical connectors to their respective lead wires.
Claim 8
Dependent Claim
136 words
In a dynamoelectric machine stator having windings disposed in slots of the stator core and extending therefrom at opposite stator ends to form end turns, a winding connector for attaching external lead wires to the leads of the windings comprising: a plurality of pairs of intermeshable electrical connectors, one connector of each pair being connected to selected winding leads and insulatingly supported near winding end turns; at least one insulating member of generally U-shaped cross section with the U straddling end turn portions for supporting the said one connector of each pair; and a multiple lead wire harness having a common external connector at one end thereof and the other connector of each pair connected to respective lead wires at the ends thereof remote from the external connector for connection to corresponding insulating member supported connectors.
