Description

TECHNICAL FIELD

[0001] The application relates to the technical field of electrical connectors, in particular to a stainless steel band armored connecting structure of armored cable. BACKGROUND

[0002] As the core carrier of power transmission and signal transmission, cables play an irreplaceable role in modern industry, construction, communication, transportation and other fields. With the complexification of industrial environment and the high frequency of signal transmission demand, the protection performance of traditional cables faces severe challenges. Therefore, armored cables effectively improve the mechanical impact resistance, gnawing resistance of rodents, chemical corrosion resistance and other performances by adding a metal protective layer to the outer layer. Armored cables are made of different material conductors in a metal sleeve with insulation material, which are processed into a flexible and solid combination.

[0003] The existing stainless steel band armored cable includes a cable core, the cable core includes at least one insulated core wire, an isolation layer is arranged outside the cable core, a filling material is arranged at the gap between the insulated core wire and the isolation layer, a stainless steel armor layer is arranged outside the isolation layer, and an outer sheath is arranged outside the stainless steel armor layer; when the stainless steel band armored cable is connected with other components, a connector is usually used for connection. First, the outer sheath of the end portion of the stainless steel band armored cable is stripped. Since the tail portion of the connector is processed with threads, the stainless steel armor layer is screwed into the tail portion of the connector. After the tail portion of the stainless steel armor layer is sleeved with a metal sleeve, crimping is performed, so as to realize fixed connection of the connector and the stainless steel armor layer. Finally, the connector is connected with other components.

[0004] When the above-mentioned related stainless steel band armored cable is connected with other components, a special tool is used to crimp the stainless steel armor layer and the metal sleeve, so as to realize fixed connection of the stainless steel armor layer and the metal sleeve. However, since the crimping force between the stainless steel armor layer and the metal sleeve is unstable, the stainless steel band armored cable is prone to falling off, which affects the connection performance between the stainless steel band armored cable and the connector. SUMMARY

[0005] In order to improve the connection performance between the stainless steel band armored cable and the connecting structure, the application provides a stainless steel band armored connecting structure of armored cable.

[0006] The application provides a stainless steel band armored connecting structure of armored cable, which adopts the following technical scheme:

[0011] The first outer sleeve is coaxially sleeved on the armor layer and the threaded sleeve, and the threaded sleeve is located in the inner cavity of the first outer sleeve. The abutment ring is coaxially fixed on the inner side wall of the first outer sleeve. The inner diameter of the abutment ring is larger than the diameter of the armor layer, and the outer diameter of the threaded sleeve is larger than the inner diameter of the abutment ring.

[0017] By adopting the above technical solution, when connecting armored cables to external components, firstly, one end of the armored cable is passed through the first outer sleeve, and the armor layer and the sheath of the cable core at the end of the armored cable are stripped. Then, since the threaded sleeve is threaded to the armor layer, the threaded sleeve is fitted onto the end of the armor layer, making the end of the threaded sleeve flush with the end of the armor layer. A welding machine is then used to weld the threaded sleeve to the armor layer through the first welding hole, pulling the armored cable until the threaded sleeve abuts against the abutment ring. Next, the sleeve is fitted onto the end of the cable core, making the end of the sleeve flush with the end of the cable core. A welding machine is then used to weld the sleeve through the second welding hole. The first and second outer sheaths are welded to the cable core, adjusted to be closer to the first outer sheath, and connected using a connecting assembly to achieve a fixed connection. A connecting joint is then installed on the end of the second outer sheath furthest from the first. Finally, external components are installed on the connecting joint.

[0056] The implementation principle of the armored cable stainless steel strip armored connection structure in this application embodiment is as follows: When connecting the armored cable to external components, firstly, one end of the armored cable is passed through the first outer sleeve 11, and the armor layer 01 and the sheath of the cable core 02 at the end of the armored cable are peeled off. Then, since the threaded sleeve 12 is threadedly engaged with the armor layer 01, the threaded sleeve 12 is fitted onto the end of the armor layer 01, making the end of the threaded sleeve 12 flush with the end of the armor layer 01. Then, a welding machine is used to weld the threaded sleeve 12 and the armor layer 01 through the first welding hole 121. The armored cable is pulled until the threaded sleeve 12 abuts against the abutment ring 13. Secondly, the threaded connector 41 is fitted onto the cable core 02, and the threaded connector 41 is rotated to make the threaded connector 41 threadedly connected to the first outer sleeve 11, thus realizing the threaded connection. The head 41 is fixedly connected to the first outer sleeve 11; then the sleeve 22 is fitted onto the end of the cable core 02, making the end of the sleeve 22 flush with the end of the cable core 02; then the sleeve 22 and the cable core 02 are welded together by a welding machine through the second welding hole 221, and the signal transmission medium ring 24 is welded to the cable core 02; the second outer sleeve 21 is adjusted so that the second outer sleeve 21 moves toward the first outer sleeve 11 until it contacts the threaded connector 41, then the second outer sleeve 21 is rotated. Since the second outer sleeve 21 is threadedly connected to the threaded connector 41, the second outer sleeve 21 is fixed to the threaded connector 41. Finally, the connecting connector 3 is installed on the end of the second outer sleeve 21 away from the first outer sleeve 11, and the external components are installed on the connecting connector 3.
