Description

Technical Field

[0001] The present invention relates to the field of cable installation, and particularly to a street clamp and a method for using the same. Background Art

[0002] When erecting cable lines, the cable lines are generally straightened and fixed by street clamps. The traditional street clamp consists of a street clamp bracket that can be installed on a wall or a utility pole and a porcelain roller for supporting the cable. When using the traditional street clamp for mid-section cable erection, in order to fix the cable on the street clamp, generally one of the following two fixing methods is adopted: First, the cable generally clings to the porcelain roller, and then the cable is bundled and fixed to the porcelain roller by means of tying wire winding. This kind of street clamp has low efficiency, and there is no unified standard for the bundling method and the bundling tightness, with great randomness, which easily leads to insecure wire fixing. After long-term use, it will become loose or even fall off. The tying wire usually adopts metal wires such as aluminum wires, which are directly wound on the outer skin of the cable, causing damage to the outer skin of the cable, easily resulting in dangers such as overheating of the cable or even leakage and short circuit, and there is a potential leakage hazard due to the direct contact between the insulated cable and the metal wire; Second, the cable is fixed on the street clamp through an externally provided wire clamp, but the structure of the externally provided wire clamp is relatively complex, the operation is inconvenient, and the use cost is relatively high.

When laying cables, it is generally divided into mid-section laying of cables and terminal laying of cables. When laying cables in the mid-section, more cables are needed to straighten the cables. When using traditional cables for mid-section laying of cables, the cables pass through the cables and are then fixed to the tiles by means of wire wrapping or external wire clamps. The work efficiency is low and the operation is inconvenient. A street code in the present embodiment is used in the middle section of cable installation, which has its own wire clamp. When installing the cable in the middle section, the wire clamp of the street code itself is used to clamp the cable. Specifically, the cable is placed in the left recessed portion. At this time, the left side of the cable is located in the left recessed portion, and the locking block 121 is attached to the fixing block 120. The right side of the cable is located in the right recessed portion on the fixing block 120. The left recessed portion and the right recessed portion are abutted to form a cable clamping channel 122. At this time, the cable is placed in the cable clamping channel 122, and the locking block 121 is installed on the fixing block 120 through a locking member. The wire clamp clamps the cable, which has the advantages of simple structure and easy use. The street code in this embodiment can be provided with 2 to 5 wire clamps on the mounting base 100, and the locking block 121 on each wire clamp can adopt different colors, corresponding to different cables, and use colors to distinguish the properties of each cable. For example, 5 wire clamps are provided on the mounting base 100, and the locking blocks 121 in the 5 wire clamps are red, green, blue, yellow, and black from top to bottom. Red, green, and blue represent the live wires of the ABC three-phase wires, yellow represents the neutral wire N, and black represents the ground wire. The live wires, neutral wires, and ground wires of the ABC three-phase wires are clamped one by one in the 5 wire clamps.
