Abstract
This application relates to a dispensed or injected structural reinforcement or hardening element, such as an injected internal strain relief, as incorporated into electrical cables. An electrical cable includes a cable portion comprising one or more electrical conductors that are positioned within an internal volume of the cable portion. Additionally, an electrical connector component is positioned at a terminating end of the cable portion. In addition, an internal strain relief element is positioned within the internal volume of the cable portion such that the internal strain relief element at least partially surrounds one or more of the electrical conductors, wherein the internal strain relief element comprises a cured injectable fluidic substance.
Claims20
An electrical cable, comprising:
- a cable portion comprising an electrical conductor that is positioned within an internal volume of the cable portion;
- a hollow tube that is positioned within the internal volume of the cable portion, wherein the hollow tube is adjacent the electrical conductor;
- an electrical connector component that is positioned at a terminating end of the cable portion;
- and
- an internal strain relief element that is positioned within the hollow tube, wherein the internal strain relief element comprises a cured injectable fluidic substance.
An electrical cable, comprising:
- a cable portion comprising a plurality of electrical conductors that are positioned within an internal volume of the cable portion;
- an electrical connector component that is positioned at a terminating end of the cable portion;
- a hollow tube that is positioned within the internal volume of the cable portion, wherein the hollow tube is adjacent the plurality of electrical conductors;
- and
- a plurality of internal strain relief elements separated by the plurality of electrical conductors and positioned within the internal volume of the cable portion such that the plurality of internal strain relief elements surround at least a portion of the plurality of electrical conductors, wherein the plurality of internal strain relief elements comprise a cured injectable fluidic substance.
An electrical cable, comprising:
- a cable portion comprising a cable bulk surrounding a plurality of electrical conductors positioned within an internal volume of the cable portion, the cable bulk defining a central region;
- an electrical connector component that is positioned at a terminating end of the cable portion;
- a hollow tube that is positioned within the internal volume of the cable portion, wherein the hollow tube is adjacent the plurality of electrical conductors;
- and
- an internal strain relief element that is positioned at the central region and between the plurality of electrical conductors, wherein:
- a shape of the cable portion is dictated by the internal strain relief element;
- and
- the internal strain relief element comprises a cured injectable fluidic substance.
