Abstract
The utility model discloses a coupling assembly of a copper conductor and an aluminum enameled wire. The coupling assembly comprises a copper conductor joint of which the insulating layer is peeled and an aluminum enameled wire joint, wherein the aluminum enameled wire joint is wound on the copper conductor joint, and a compression sleeve is sleeved over the copper conductor joint. The inner wall of the compression sleeve is axially provided with a spiral embedding groove, where the aluminum enameled wire joint is embedded in. One end of the compression sleeve is arranged on the sealing ring at the leading-out end of the aluminum enameled wire joint and the copper conductor joint, and a thermal-shrinking type protecting pipe is sleeved over the insulating layer from the outside of the compression sleeve to the aluminum enameled wire joint. The coupling assembly is simple and reasonable in structure, and convenient for installation and use, ensures isolation of the joint from ambient air after connection, and prevents oxidation. The coupling assembly has excellent stability and may not be easily loosened when pulled or dragged, thereby effectively ensuring the normal use of the joint.
Description
Technical field
The utility model relates to a kind of wire rod syndeton, is specially the coupling assembling of a kind of copper conductor and aluminium enamel-covered wire.
Background technology
The connected mode that copper conductor mostly adopts crimping to be connected with aluminium enamel-covered wire, removes the outer insulation of copper conductor and aluminium enamel-covered wire to form joint during crimping, re-use crimp head and connect, and is finally wound around electrical adhesive tape and carries out insulation processing.And the press connection joint structure of this insulation processing is reasonable not, after connection, can not effectively completely cut off air, joint is easily oxidized, and stability is not good, after long-time use easily Tensile, pull impact and become flexible, cause joint loose contact.
Utility model content
The purpose of this utility model is to provide the coupling assembling of a kind of copper conductor and aluminium enamel-covered wire, press connection joint structure with traditional connected mode in solution prior art is reasonable not, after connection, can not effectively completely cut off air, joint is easily oxidized, and stability is not good, after long-time use easily Tensile, pull impact and become flexible, cause the problem of joint loose contact.
For achieving the above object, the technical solution adopted in the utility model is:
The coupling assembling of a kind of copper conductor and aluminium enamel-covered wire, it is characterized in that: include copper wire lead and the aluminium enamel-covered wire joint of peelling off insulating barrier, described aluminium enamel-covered wire joint is wrapped in copper wire lead, in described copper wire lead, cover has clamping sleeve, described clamping sleeve inwall is axially arranged with spiral caulking groove, described aluminium enamel-covered wire joint is embedded in the spiral caulking groove of clamping sleeve, described clamping sleeve one end is provided with the sealing ring being nested with on aluminium enamel-covered wire joint and copper wire lead exit, described clamping sleeve outside to the insulating barrier upper sleeve gasket of copper conductor and aluminium enamel-covered wire has thermal shrinkage type protecting pipe.
Described a kind of copper conductor and the coupling assembling of aluminium enamel-covered wire, is characterized in that: between described sealing ring and protecting pipe, by fin and draw-in groove, closely cooperate.
The beneficial effects of the utility model are:
The utility model is simple and reasonable, easy to install, adopts the design of protecting pipe fitted seal ring, has effectively guaranteed the isolation performance of joint and outside air after connection, prevents oxidative phenomena; Employing arranges the design of spiral caulking groove at clamping sleeve inwall, joint is had good stability, and joint is also difficult for loosening when being subject to stretching, pulling, and has effectively guaranteed the normal use of joint.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
