Embodiment Construction

[0016] The present invention will be further described below in conjunction with accompanying drawing:

[0017] Such as figure 1 , one A special intermediate connector for fireproof cables, which includes a copper tube 1, a ceramic ring sleeve 2, an end bolt 3, an end nut 4 and a compression ring 5, the ceramic ring sleeve 2 is arranged on the inner wall of the copper tube 1, and the two ends of the copper tube 1 are respectively One end bolt 3 is connected, and each end bolt 3 is threadedly connected with one end nut 4 .

[0018] A compression ring 5 is provided between the end bolt 3 and the end nut 4 .

[0019] Such as figure 2 , There are chamfers 6 on both sides of the compression ring 5 . The corresponding positions of the end bolt 3 and the end nut 4 have a chamfered slope matching with the chamfer 6 of the compression ring 5 . Such as image 3 The compression ring 5 is provided with notches 7 . The notch 7 can compress the compression ring 5 to re...

Abstract

The invention discloses an intermediate connector special for fireproof cables. The intermediate connector special for the fireproof cables is characterized by comprising a copper pipe (1), a ceramic ring sleeve (2), terminal bolts (3), terminal nuts (4) and compression rings (5), wherein the ceramic ring sleeve (2) is arranged on the inner wall of the copper pipe (1); the two ends of the copper pipe (1) are connected with the terminal bolts (3); and each terminal bolt (3) is in threaded connection with one terminal nut (4). In the intermediate connector special for the fireproof cables, the strength of a branch box can be effectively increased by connecting the terminal bolts with the terminal nuts, and heat can be effectively insulated and a good insulation effect can be achieved by arranging the ceramic ring sleeve; and because the branch points and the joints of the fireproof cables are the weakest parts of the fireproof cables for insulation, an inter-phase short circuit, a short circuit between wires and a short circuit between a wire core and an outer sheath can be effectively prevented by a ceramic liner.

Description

technical field [0001] The invention relates to a cable connection device, in particular to a special intermediate connector for fireproof cables. Background technique [0002] At present, fireproof cable intermediate connectors are used to connect fireproof cables. Fireproof cables have high insulation and heat insulation properties. However, the existing fireproof cable intermediate connectors cannot effectively insulate heat and insulation, and are easy to break at the connection. Disable fireproof cables at the connection. Contents of the invention [0003] The purpose of the present invention is to provide a special intermediate connector for fireproof cables, which can solve the technical problems of insulation, heat insulation and firm connection. [0004] Technical scheme of the present invention is: [0005] A special intermediate connector for fireproof cables, which includes copper pipes, ceramic ring sleeves, end bolts, end nuts and compression rings. One...
