Abstract
Power cables that include plug housings having an improved appearance as well as employ a halogen-free cable while providing adequate fire resistance. One example provides a power cable having cable plug with a substantially unitary body. Another example provides a power cable that is formed using halogen-free materials. To provide adequate fire protection, a strain relief formed using multiple materials is used.
Claims23
A cable plug comprising:
- a strain relief that allows passage of a cable;
- an assembly comprising a nonconductive insulative housing and power and ground conductors, the assembly further comprising passages, the passages connected to the conductors;
- a plurality of contact pins located in passages in the assembly and having a contact portion extending beyond the assembly such that contact may be made with opposing contacts in a compatible connector receptacle;
- a circuit board fixed to the assembly and contact pins;
- a light-emitting diode fixed to the circuit board;
- a magnetic attraction plate positioned around the contact portion of the contact pins;
- and
- a cylindrical unitary housing made from a single piece of material and having a first opening for the cable and a second opening for the attraction plate, the attraction plate and cylindrical unitary housing enclosing the assembly, the plurality of contacts, the circuit board, and the light-emitting diode,
- wherein the magnet attraction plate and the contact portion protrude through a second opening in the unitary housing.

A cable plug comprising:
- a unitary housing made from a single piece of material and having a cylindrical shape and having a first opening at an end to accept a cable;
- an assembly housed in the unitary housing and comprising a nonconductive housing and power and ground conductors, the power and ground conductors coupled to the cable;
- a circuit board coupled to the assembly;
- a plurality of contacts coupled to the circuit board;
- a magnetic attraction plate positioned around the plurality of contacts, the attraction plate and the plurality of contacts protruding through a second opening in the unitary housing;
- a first light-emitting diode coupled to the circuit board;
- a first light pipe over the first light-emitting diode;
- and
- a first light insulator surrounding the first light-emitting diode and the first light pipe to limit illumination in a first and second direction and to allow illumination in a third direction,
- wherein a third opening in the unitary housing is aligned with the first light-emitting diode in the third direction.
