Abstract
Abstract Disclosed is an arrangement for providing an electrical connection to the enamelled wire of a coil of an electrical motor. The arrangement includes a circuit board carrying at least one conductive component such as an electrical trace on the surface of the circuit board. A conductive pin-type contact, also carried by the circuit board, is electrically connected to the conductive component. An insulating body is carried by the electrical motor and includes passageways for receiving at least two pin-receiving receptacle terminals. The receptacle terminals have inwardly-extending rib members for engaging the enamelled wire when the enamelled wire and the pin-type contact are inserted therein. The rib members are operative to penetrate the enamel covering to establish electrical contact with the wire.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
120 words
An arrangement for providing an electrical connection to the enamelled wires of the coil of an electrical motor, comprising, in combination: a circuit board carrying at least one conductive component; a conductive pin-type contact carried by said circuit board and electrically connected to said conductive component; an insulating body carried by said electrical motor, said insulating body defining at least two receptacle-receiving passageways therein; and conductive-pin receiving terminals having wall means defining a pin-receiving cavity and engaging means associated with said wall for electrical engagement with one said enamelled wire and one said pin-type contact inserted into said cavity, said engaging means operative to penetrate the enamel covering said wire to establish electrical contact with said wire and said pin.
Claim 2
Dependent Claim
120 words
An arrangement for providing an electrical connection to the enamelled wires of the coil of an electrical motor, comprising, in combination: a circuit board carrying at least one conductive component; a conductive pin-type contact carried by said circuit board and electrically connected to said conductive component; an insulating body carried by said electrical motor, said insulating body defining at least two receptacle-receiving passageways therein; and conductive-pin receiving terminals having wall means defining a pin-receiving cavity and engaging means associated with said wall for electrical engagement with one said enamelled wire and one said pin-type contact inserted into said cavity, said engaging means operative to penetrate the enamel covering said wire to establish electrical contact with said wire and said pin.
Claim 3
Dependent Claim
43 words
The combination of claim 1 wherein said motor further includes latching means carried by said insulating body for latching to said circuit board, said receptacle terminals arranged to mate with said pin-type contacts as said latching means are latched to said circuit board.
Claim 4
Dependent Claim
18 words
The combination of claim 1 wherein said engaging means comprise inwardly-extending rib members formed in said receptacle terminal.
Claim 5
Dependent Claim
32 words
The combination of claim 1 wherein said receptacle terminal has a pin-receiving end and defines a slot extending from said pin-receiving end along at least two-thirds the length of said receptacle terminal.
Claim 6
Dependent Claim
19 words
The combination of claim 1 wherein said insulating body is supported by a stack of plates of the motor.
Claim 7
Dependent Claim
25 words
The combination of claim 1 wherein said engaging means comprises an end section of said receiving terminal wall conically tapered in the direction of insertion.
Claim 8
Dependent Claim
21 words
The combination of claim 3 wherein each said rib member has a single edge for penetrating the enamel covering said wire.
Claim 9
Dependent Claim
20 words
The combination of claim 3 wherein each said rib member has two edges for penetrating the enamel covering said wire.
Claim 10
Dependent Claim
42 words
The combination of claim 1 wherein said insulating body includes wall means defining said receptacle-receiving passageways, said wall means slotted along their length to produce a resiliently-expandable passageway which augments the mating contact force of said engaging means with said pin-type contact.
