Embodiment
[0027] see image 3 , Figure 4 and Figure 5 , the connection method of armored cable wrapping steel tape, mainly includes the following steps:
[0028] First, proceed to step S1: when opening the double-layer steel strip, the first layer of steel strip 2 is opened from the left cutting position A with a sharp knife, and the second layer of steel strip 3 is opened from the right cutting position B with a sharp knife;
[0029] Step S2: After opening the above two layers of steel strips 2 and 3 and separating them to the two sides, the next step is to strip off the sheath layer and insulating layer to expose the copper conductor in the center layer;
[0030] Then step S3: Then, according to the phase sequence, the copper conductor and the copper conductor are clamped and connected with the C-shaped clamp 4. If the five-core cable is connected to the three-core branch, then according to the color separation requirements, one phase is connected to the live wire, and the two-pha...

Abstract
The invention discloses a connecting method of wrapping steel strips for armored cables. The method comprises the following steps of: (1) firstly, opening two layers of steel strips, opening the first layer of the steel strip from a left position with a sharp knife and opening the second layer of the steel strip from a right position with the sharp knife; (2) splitting the two layers of the opened steel strips apart and then stripping a protection layer and an insulation layer in a cable so as to expose a conductor in the central layer; (3) connecting the conductors of the groups of well-stripped cables with a C-shaped clamp according to the phase sequence; (4) carrying out a recovery process, binding up the C-shaped clamp and the conductors with an insulation strip and a hot melt adhesive tape and then stacking the steep strips at both sides together according to an original opening direction; and (5) finally, binding up the steel strips at the left and the right and the combined cables together with steel wires. The connecting method provided by the invention is novel and has a simple steel strip recovery process, and a joint position is seamless without redundant part so that poor insulativity or breakdown cannot be resulted in.
Description
technical field [0001] The invention relates to the field of cables, in particular to a connection method for wrapping steel strips of armored cables. Background technique [0002] Armored cables are made of different material conductors packed in metal sleeves with insulating materials and processed into a bendable solid assembly. The armored cable mechanical protection layer can be added to the cable of any structure to increase the mechanical strength of the cable and improve the ability to resist erosion. It is designed for areas that are susceptible to mechanical damage and erosion. The purpose of adding an armor layer to the cable is not only to enhance the mechanical protection such as tensile strength and compressive strength to prolong the service life, the armored cable also has a certain resistance to external forces, such as preventing mice from biting, so as not to cause electricity through the armor. Transmission problem. [0003] In the process of making arm...
