Abstract

The utility model discloses a cable connecting fitting part. In order to provide a cable connecting device which can work even when the both ends of the joints of a cable are not on the same axial cord or the ends of the cable are bended suddenly, a universal joint which is provided with axial direction butt joint component outer sleeves and axial direction butt joint components installed on the both ends of outer sleeve tubes is proposed. The universal joint comprises a locating piece and a universal head. The outer end surface of the universal head is provided with a conducting ring and a protection ring (protective cover) which are in butt joint with each other in the axial direction. Adhesive or electric conduction adhesive is arranged between the outer sleeves, between the locating piece, the outer sleeve tubes and the universal head, and between the universal head, the protection ring, the conducting ring and the metal surfaces of the ends of the cable. An anticorrosive coating is coated on the bare surface of the cable connecting device.

Description

Universal electric cable connecting device

The utility model belongs to the cable connection fittings.

The different length specification is made in the different requirements of the cable that uses because of making, constructing and use at present, needs in use to connect with jockey, and adopts maintenance by gas pressuriztion.Present this jockey generally is to adopt the plumbous matter sleeve pipe that adds infusion epoxy resin by soldering, soldering, or described by the bonding all kinds of forming metal cover compositions of bonding agent as Chinese patent CN87205620, CN87205623 and CN88209720.This cable connecting arrangement is because the terrain trend of cabling causes the cable joint two ends not to be in same axis or cable socket suddenly during case of bending; and to cable louding not when the crooked suddenly existing cable joint of same axis or cable socket installs second protection additional, then can't construct.

Be not in same axis or cable socket suddenly during case of bending for providing a kind of when the cable joint two ends, still the cable connecting arrangement that can construct proposes the utility model.

The utlity model has axially to outer tube that is connected into and axially the universal joint that is contained in the outer tube two ends being connected into.Axially the universal joint that is connected into is made up of the Universal-head that is contained in axial butt joint half locating piece in the endoporus of outer tube two ends, axially docks and form an above through hole, the Universal-head end face be equipped with the semiconductive ring of axial butt joint and axially butt joint and forming be convenient to be installed with the elongated slot guard ring (or protective cover) of the Universal-head rotation of cable.Between the outer tube, between locating piece and outer tube, the Universal-head, adopt bonding agent or electrically conducting adhesive bonding between Universal-head and guard ring, conducting ring, the cable socket metal surface respectively; scribble corrosion protective covering at the cable connecting arrangement exposed surface; universal joint can be bowl shaped structure, also can be spherical structure.

The utility model adopts axially butt joint, be convenient to the cable joint that continues with soldering or bonding method cable connecting arrangement be installed, the gimbal structure of employing, make be not in same axis or the crooked suddenly cable joint in termination, still can connect construction, thereby reach the utility model purpose.
