Embodiment 1

[0023] Embodiment 1: The number of screw-connected intermediate connection terminals 3 in the internally threaded seamless pipe 1 is three, which can realize the continuous connection of three-core cables. Unscrew the screw fastening screw 5 counterclockwise, connect the ends of the cables on both sides to the two ends of the screw-connected intermediate connection terminal 3 as shown in the figure, and then tighten the screw fastening screw 5 clockwise to fasten the cables on both sides cable. Operate the remaining two screw-type intermediate connection terminals 3 in the same way. A peep hole 6 is provided at the middle end of the plane where the screw hole is provided, and the peep hole 6 is mainly used for detecting temperature and observing whether the wire connection is good. The exposed part of the cable core is protected by high-temperature resistant heat-shrinkable tube and high-pressure waterproof self-adhesive tape.

Embodiment 2

[0024] Embodiment 2: The number of screw-connected intermediate connection terminals 3 in the internally threaded seamless pipe 1 is 4, which can realize the continuous connection of four-core cables. Unscrew the screw fastening screw 5 counterclockwise, connect the ends of the cables on both sides to the two ends of the screw-connected intermediate connection terminal 3 as shown in the figure, and then tighten the screw fastening screw 5 clockwise to fasten the cables on both sides cable. Operate the remaining three screw-type intermediate connection terminals 3 in the same way. A peep hole 6 is provided at the middle end of the plane where the screw hole is provided, and the peep hole 6 is mainly used for detecting temperature and observing whether the wire connection is good. The exposed part of the cable core is protected by high-temperature resistant heat-shrinkable tube and high-pressure waterproof self-adhesive tape.

Abstract

The invention discloses a mineral cable multi-core intermediate connector, belongs to the field of cable installation, and solves the problems that the traditional intermediate connector is troublesome to install and has poor degree of safety of installation, and conductors cannot be tightly connected. The mineral cable multi-core intermediate connector mainly comprises an internal threaded seamless pipe, wherein the two ends of the internal threaded seamless pipe are respectively provided with a gland sealing end, and at least one screwed connection intermediate connecting terminal is arranged in the internal threaded seamless pipe. The mineral cable multi-core intermediate connector provided by the invention has the advantages of simple and convenient installation, high strength and safety, tight connection between the cable conductors, good conductive effect, simple structure, easiness in manufacturing, and high practical value, and can be widely applied in the field of cable installation.

Description

technical field [0001] The invention relates to a cable connection device, in particular to a multi-core intermediate connector for mineral cables. Background technique [0002] Since the production length of mineral insulated cables is limited by the length of the cable raw materials, or is affected by the configuration of different electrical circuit cables during the laying-out process, during the cable laying and installation process, it is necessary to use an intermediate connector to connect two cables of the same specification. Ensure that the line length requirements are met. [0003] In actual use, common brass tubes are often used as outer sheath tubes, and copper crimping tubes are used for crimping connections whether single-core or multi-core. Chinese Patent No. CN 102468640A, published on May 23, 2012, the name of the invention is a special intermediate connector for fireproof cables. This application discloses an intermediate connector for connecting cables t...
