Problems solved by technology

Although the copper conductor can be reused, it also requires a processing fee of 2,000 yuan / ton, which is 6,044 yuan. The insulation and shielding materials cannot be reused and must be scrapped
[0005] Therefore, the fixed and continuous connection of the wires in the prior art is difficult to meet the actual production requirements of CCV, especially for large-section split conductors. Every time a wire is replaced, the machine must be started and stopped once, and continuous production cannot be performed. This not only wastes a lot, but also affects production. efficiency

Embodiment 1

[0026] Embodiment 1: see figure 1 — Figure 7 , the cross-linked cable catenary type continuous vulcanized wire connector of the present invention includes compression sleeves 1.1 and 1.2 respectively used to connect two wires at the left and right ends, and a connecting sleeve 2 in the middle to form a traction rotatable connector in series ( figure 1 ). Among them, the connection wire compression sleeve 1.1, 1.2 ( figure 2 ), an integral structure consisting of three sections of a hollow crimping tube (sleeve for short) 5.1 with an outer diameter not greater than the diameter of the wire, a thin neck 5.2, and an embedded pulling head 5.3 with a diameter larger than the thin neck. The inner wall of the hollow crimping tube 5.1 is processed with The internal thread can increase the frictional force with the wire to ensure that the crimping is firm and reliable. The head 5.3 has a radial through hole 5.4 for inserting the anti-rotation pin. Intermediate linker 2 ( image 3...

Embodiment 2

[0027] Example 2: see Figure 8 , 9 , as in embodiment 1, wherein the continuous wire is a round wire concentric twisted wire. The intermediate connector is a connecting rod 6 with an enlarged spherical head 6.1 and 6.2 at both ends. The compression sleeve connecting the two wires is an integral structure composed of hollow crimping tubes 1.1.1 and 1.2.1 whose outer diameter is not larger than the diameter of the wires, and an axial blind hole connection part 1.1.2 and 1.2.2 at the other end. The end has a shrinkage cavity structure, and the blind hole section has a gap 1.6.1 that can be embedded in the sub-methine connecting rod. As mentioned above, there are radial through holes in the blind hole section and the head of the methionine for inserting anti-rotation pins. The CCV production method is basically the same as that of Example 1, the front and rear wires 4.1.1 and 4.2.1 are connected, and an outer layer is respectively stripped off and inserted into a compression s...

Embodiment 3

[0028] Embodiment 3: see Figure 10 , 11 , as mentioned above, the intermediate connector is omitted, and the non-connecting wire ends of the two connecting wire compression sleeves 1.1.3 and 1.2.4 respectively have the pulling head 1.1.7 in the structure of half sub-methine, and the pulling head 1.1.7 for pulling and inserting. The blind hole section 1.2.3 of the mouth, the blind hole section and the sub-methine head each have a radial insertion pin through hole 1.1.8, and the blind hole section has a gap 1.2.3 that can be embedded into the sub-methine head. When in use, the traction head of one compression sleeve is embedded, and the blind hole section of the other compression sleeve is provided with a constriction to form a rotatable traction connection, and the pin is inserted to be relatively fixed. The production method is basically the same as above.

Abstract

The invention relates to a discontinuous conductor connector for catenary continuous vulcanization (CCV) production of cross-linked cables and a non-stop connection preparation method. The connector is characterized in that front and rear splicing conductors are provided with a compaction sleeve respectively; one end of the compaction sleeve is in rotatable traction connection with a connecting sleeve or a connecting rod mutually or respectively; a connecting coincidence part is provided with insertable pins so as to form a conductor connector; after a front conductor and a rear conductor areassembled and connected, the conductor connector ensures that connected front and rear conductors can rotate respectively; and after the conductor connector is subject to up traction, the pins are immediately inserted to ensure that the front and rear conductors can only synchronously rotate. The connector and the preparation method can realize the CCV non-stop multi-conductor splicing continuousproduction of the cross-linked cables, avoid the waste caused by the on / off of each conductor, also greatly improve production efficiency, and solve the problem puzzled for a long time that the continuous production cannot be performed during cross-linking CCV production.

Description

technical field [0001] The invention relates to an interrupted wire connector for catenary continuous vulcanization (CCV) production of cross-linked cables, and a preparation method for CCV cross-linked cables, which can ensure the continuous production of CCV cross-linking machines without stopping the machine, and is especially suitable for the division of ultra-high voltage cross-linked cables Continuous connection of conductor wires and continuous production without stopping. Background technique [0002] Cable cross-linking (such as cross-linked polyethylene insulation) catenary continuous vulcanization (CCV) preparation requires continuous start-up, for example, generally about ten days. However, due to the limitation of the conductor weight, loading capacity and other factors, it is impossible to use the whole conductor at one time. In this way, in the continuous production process, the conductors must be connected continuously to ensure the continuous production of t...
