Abstract
An electrical crimp connector (1) comprises a crimp barrel (3) located within an insulating sleeve (4), and a quantity of gel (5) located within each end region of the insulating sleeve at each end of the crimp barrel. Each quantity of gel contains an aperture (10) to allow wires (2) to be inserted into the crimp barrel. Once the connector has been crimped, the gel located within each end region of the insulating sleeve seals it against moisture ingress, forming a moisture-resistant electrical connection.
Claims11
A device for forming a butt splice between two or more elongate electrical conductors, which comprises a crimp barrel, an electrically insulating sleeve, two quantities of gel and two ferrules, wherein the crimp barrel has two open ends, the sleeve is located about and extends beyond the ends of the crimp barrel and each quantity of gel is located within an end region of the insulating sleeve beyond a respective end of the crimp barrel for sealing each end of the splice against ingress of moisture, and each ferrule is located beyond a respective end of the crimp barrel, between the insulating sleeve and the gel, and wherein each quantity of gel contains an aperture to allow the insertion of one or more elongate electrical conductors into each end of the crimp barrel.
A device for forming a butt splice between two or more elongate electrical conductors, which comprises a crimp barrel, an electrically insulating sleeve, two quantities of gel and two ferrules, wherein the crimp barrel has two open ends, the electrically insulating sleeve is located about and extends beyond the ends of the crimp barrel, each quantity of gel is located within an end region of the insulating sleeve beyond a respective end of the crimp barrel for sealing each end of the splice against ingress of moisture, and each ferrule is located beyond a respective end of the crimp barrel between the insulating sleeve and the gel, and is capable of being crimped in order to compress at least part of the gel against an electrical conductor inserted into the crimp barrel and/or to provide strain relief for the electrical conductor.
A method of forming a butt splice between two or more insulated elongate electrical conductors by means of a device which comprises a crimp barrel, an electrically insulating sleeve, two quantities of gel and two crimpable ferrules, wherein the crimp barrel has two open ends, the sleeve is located about and extends beyond the ends of the crimp barrel and each quantity of gel is located within an end region of the insulating sleeve beyond a respective end of the crimp barrel for sealing each end of the splice against ingress of moisture, and each crimpable ferrule is located beyond a respective end of the crimp barrel between the insulating sleeve and the gel, and wherein each quantity of gel contains an aperture to allow the insertion of one or more elongate electrical conductors into each end of the crimp barrel, the method comprising:
- (i) stripping a length of insulation from the end of each conductor;
- (ii) inserting one or more of the conductors into each end of the device so that the end of each conductor extends into the crimp barrel and a portion of the insulation is surrounded by the insulating sleeve;
- and
- (iii) crimping each ferrule about the insulation of each conductor inserted therein.
