Abstract
An insulation-displacement terminal (T) includes opposed side walls (12) and a wire-receiving space therebetween. Insulation-displacement portions (17) project from the side walls (12) and into the wire-receiving space. Each insulation-displacement portion (17) has two bases (18) that project from longitudinally spaced positions on the corresponding side wall (12). A blade (19) has two panels folded from the respective bases (18) and projecting further into the wire-receiving space. The folded blades (19) cut sharply into the resin coating (Wa) of a wire (W) urged into the wire-receiving space, and the bases (19) resist pulling forces on the wire (W). Therefore, a loose movement of the wire (W) in its longitudinal direction can be prevented.
Claims19
An insulation-displacement terminal fitting (T), comprising:
- an elongate bottom wall (11), first and second opposed side walls (12) extending up from the bottom wall (11) and defining a wire-receiving space therebetween, first and second insulation-displacement portions (16;
- 20;
- 23;
- 26) projecting inwardly from the respective side walls (12) and into the wire-receiving space, each said insulation-displacement portion (16;
- 20;
- 23;
- 26) comprising first and second bases (18;
- 21;
- 24;
- 27) formed unitarily with the respective side wall (12) and being spaced apart longitudinally, each said insulation-displacement portion (16;
- 20;
- 23;
- 26) further comprising a blade (19;
- 22;
- 25;
- 28) having first and second blade panels folded further into the wire receiving space from ends of the respective first and second bases (18;
- 21;
- 24;
- 27) most distant from the respective side wall (12).
An insulation-displacement terminal fitting (T) for use with a wire (W) having a core (Wa) with an outside diameter, the wire (W) further having an insulating coating (Wb) surrounding the core (Wa), the insulation-displacement terminal fitting (T) comprising:
- an elongate bottom wall (11), first and second opposed side walls (12) extending up from the bottom wall (11) and defining a wire-receiving space therebetween, first and second opposed insulation-displacement portions (16;
- 20;
- 23;
- 26) projecting inwardly from the respective side walls (12) and into the wire-receiving space, each said insulation-displacement portion (16;
- 20;
- 23;
- 26) comprising first and second bases (18;
- 21;
- 24;
- 27) formed unitarily with the respective side wall (12) and converging toward one another from spaced apart locations along the respective side wall (12), each said insulation-displacement portion (16;
- 20;
- 23;
- 26) further comprising a blade (19;
- 22;
- 25;
- 28) having first and second blade panels folded further into the wire receiving space from ends of the respective first and second bases (18;
- 21;
- 24;
- 27) most distant from the respective side wall (12), the blades (19;
- 22;
- 25;
- 28) on the opposed first and second insulation-displacement portions (16;
- 20;
- 23;
- 26) being spaced from one another by a distance less than the diameter of the core (Wa), the bases (18;
- 21;
- 24;
- 27) of the first insulation-displacement portion (16;
- 20;
- 23;
- 26) being spaced from the bases (18;
- 21;
- 24;
- 27) of the second insulation-displacement portion (16;
- 20;
- 25;
- 28) by a distance not less than the diameter of the core (Wa).
