Abstract

A crimped terminal (or splice) has a housing (10) including a barrel (11) receiving an insert sleeve (13). The barrel (11) has a lug (12) received in a complementary notch (14) formed in the insert sleeve (13), thereby circumferentially keying the insert sleeve (13) to the barrel (11), preventing relative rotation therebetween, and reinforcing the housing (10) during the crimping process. This eliminates cracking of the housing (10) during crimping while improving heat dissipation.

Claims

1. A crimped assembly for terminating an end of a wire, the assembly having a housing, the housing having a hollow barrel provided with an insert sleeve which is received within the barrel and abuts against an interior wall thereon, wherein the wire is received through the open end of the barrel and within the insert sleeve, and wherein the housing is crimped over the insert sleeve and the wire, thereby retaining the wire;

a protruding lug on the barrel, the protruding lug extends axially from the interior wall, radially inwardly of the barrel, and in the direction toward the open end thereof, and the insert sleeve having a notch receiving the protruding lug on the barrel, thereby circumferentially keying the insert sleeve to the barrel and preventing relative rotation therebetween, improving heat dissipation, and reinforcing the housing and the insert sleeve when the housing is crimped over the insert sleeve and the wire.

2. The assembly of claim 1, further including a tapered insertion ring within the barrel for guiding the wire therein, and the barrel having an internal indentation rearwardly of the tapered insertion ring and substantially adjacent thereto, thereby retaining the tapered insertion ring in the barrel.

3. The assembly of claim 2, wherein the tapered insertion ring is formed from a plastic material.

4. The assembly of claim 1, wherein the insert sleeve is perforated.

5. The assembly of claim 1, wherein the crimped assembly comprises a terminal for a single wire.

6. The assembly of claim 1, wherein the crimped assembly comprises a splice between respective wires.

7. The assembly of claim 1, wherein the wire has a plurality of strands, and wherein a removable funnel is inserted through the open end of the barrel of the housing, thereby facilitating insertion of the wire strands into the barrel.

8. The assembly of claim 7, wherein the funnel has a forward nipple received in the barrel.

9. The assembly of claim 8, wherein the funnel is split longitudinally to facilitate removal of the funnel following insertion of the wire into the barrel and prior to the crimping operation.

10. A crimped assembly for terminating an end of a wire, the assembly having a housing comprising a hollow barrel provided with an open end, wherein an insert sleeve is received within the barrel, wherein the wire is received through the open end of the barrel and within the insert sleeve, and wherein the housing is crimped over the insert sleeve and the wire, thereby retaining the wire, a tapered insertion ring is provided within the barrel for guiding the wire therein, the barrel having an internal annular indentation rearwardly of the tapered insertion ring and substantially adjacent thereto, thereby retaining the tapered insertion ring, a protruding lug is provided on the barrel, the insert sleeve having a notch receiving the protruding lug on the barrel, the cooperation of the protruding lug on the notch circumferentially keying the insert sleeve to the barrel and preventing relative rotation therebetween, improving heat dissipation, and reinforcing the housing and the insert sleeve when the housing is crimped over the insert sleeve and the wire.

11. A crimped assembly for terminating an end of a wire having a plurality of strands, the assembly having a housing comprising a hollow barrel provided with an open end, wherein an insert sleeve is received within the barrel, wherein the wire is received through the open end of the barrel and within the insert sleeve, and wherein the housing is crimped over the insert sleeve and the wire, thereby retaining the wire, a removable funnel is inserted through the open end of the barrel, to facilitate insertion of the wire strands into the barrel, a protruding lug is provided on the barrel, the insert sleeve having a notch receiving the protruding lug on the barrel, thereby circumferentially keying the insert sleeve to the barrel and preventing relative rotation therebetween, improving heat dissipation, and reinforcing the housing and the insert sleeve when the housing is crimped over the insert sleeve and the wire.
