Abstract
Described herein are methods, devices, and systems for electrically connecting a plurality of shielded cable shields using a shield bridge conductor embedded in a polymer structure. The shield bridge conductor may electrically connect the cable shields of two or more phase conductor cables and a ground conductor cable.
Claims20
An apparatus, comprising:
- a plurality of conductors, wherein each conductor of the plurality of conductors is configured to conduct a different phase of a multi-phase power source;
- a plurality of cable shields, wherein each cable shield of the plurality of cable shields is configured to surround a respective one of the plurality of conductors;
- and
- a shield bridge comprising:
- a shield bridge conductor,
- a ground conductor cable, and
- a plurality of bonds,
- wherein each bond of the plurality of bonds is electrically connected to a respective cable shield of the plurality of cable shields, and
- wherein the shield bridge conductor is connected to the plurality of bonds and the ground conductor cable such that a short circuit is created between the plurality of cable shields using the shield bridge conductor.
6 more elements
A method, comprising:
- providing a plurality of shielded cables, each cable comprising a conductor surrounded by a cable shield, with an inner insulation between the conductor and the cable shield, and an outer insulation surrounding the cable shield;
- for each shielded cable of the plurality of shielded cables:
- stripping, from the shielded cable, a portion of the outer insulation to expose a portion of the respective cable shield;
- pulling the exposed portion of the respective cable shield from the cable to form a shield wiring electrically connected to the cable shield;
- electrically interconnecting shield wirings of the plurality of shielded cables to form a shield bridge conductor between the plurality of shielded cables;
- and
- connecting a ground conductor cable to an end of the shield bridge conductor.
4 more elements
A power device, comprising:
- a plurality of conductors, wherein each conductor of the plurality of conductors is configured to conduct a different phase of the power device;
- a plurality of cable shields, wherein each cable shield of the plurality of cable shields is surrounded by a respective one of the plurality of conductors;
- and
- a housing comprising:
- a shield bridge comprising:
- a shield bridge conductor,
- a ground conductor cable, and
- a plurality of bonds,
- wherein each bond of the plurality of bonds is electrically connected to a respective cable shield of the plurality of cable shields, and
- wherein the shield bridge conductor is connected to the plurality of bonds and the ground conductor cable such that a short circuit is created between the plurality of cable shields using the shield bridge conductor.
