Example Embodiment

[0019] Example 1

[0020] like Figures 1 to 6 As shown, this embodiment provides a power junction tube, which is made of thermoplastic elastomer as a whole, including a connecting tube 1, two fixing tubes 2 and a circular cover plate 3; the connecting tube 1 is a hollow cylindrical structure, and its The inner wall is provided with an internal thread 11; the fixed pipe 2 is a cylindrical structure matched with the connecting pipe 1, one end of the fixed pipe 2 is provided with a first external thread 21 matching the internal thread 11, and the other end is provided with a round cap The second external thread 22 matched with the plate 3; the fixed pipe 2 includes a tapered section and a fixed section, the tapered section and the fixed section have the same outer diameter; the inner diameter of the tapered section gradually decreases from inside to outside , forming a tapered structure 23 on the inner wall; the wall of the tapered structure 23 is provided with a barbed one-way...

Example Embodiment

[0021] Example 2

[0022] like Figures 1 to 6 As shown, this embodiment provides a kind of power connection pipe, and the difference from Embodiment 1 is that the fixers are arranged in the shape of a "ten" and installed on the fixing section; the bottom of the fixing plate 27 is provided with a Anti-slip rubber anti-slip gasket; the middle section of the connecting pipe 1 is provided with an observation window made of polycarbonate material; the thermoplastic elastomer includes the following components: 50-60 parts by weight of ethylene acrylate elastomer rubber , 40-50 parts by weight of sarin resin, 5-10 parts by weight of epoxy resin, 4-6 parts by weight of zinc stearate, 10-30 parts by weight of filler, 3-5 parts by weight of hexamethylene bismuth Amine carbamates.

Abstract

The invention provides a power wiring pipe, which adopts split connection. The power wiring pipe comprises movably-connected fixing pipes for fixing a line and a connection pipe connecting the two fixing pipes, wherein the connection pipe and the fixing pipes are in threaded connection; one end of the fixing pipe has a conical structure, the inner wall of the conical structure is provided with a clamping tongue, and the other end is provided with multiple fixing devices; a round cover plate and the fixing pipe are in movable connection; the inner diameter of an annular cover is consistent withthe maximum inner diameter of the fixing pipe, and the inner wall is provided with a rubber dustproof plate. The power wiring pipe has the advantages of light weight, simple structure, good sealing performance and the like.

Description

technical field [0001] The invention relates to the technical field of electric equipment maintenance, in particular to an electric connection tube. Background technique [0002] In the prior art, crimping or winding connection is often used for connection between wires. For crimping connection, when the wire bears a large tensile force, it is necessary to increase the crimping length to prevent falling off during use; for winding connection, the joint process is rough and the reliability is poor. Therefore, special-purpose power junction tubes appear in the market, and the structure of the power junction tubes in the prior art is relatively simple, usually adopting metal connectors to simply fix the two connection heads respectively and then connect them; the fixing method usually adopts Simple bolt tightening secures. This kind of fixing method has poor fixing effect, and the long-term use of bolts is easy to damage the rubber insulation layer coated on the surface of th...
