Description

Technical Field

[0001] This application belongs to the field of cable construction technology, specifically relating to a wire tensioning and fixing device. Background Technology

[0002] In the existing technology, during the circuit erection process, needle-type porcelain insulators are usually used to support or suspend the conductors and form electrical insulation between the tower and the conductors. Traditional needle-type porcelain insulators are usually made of insulating parts such as porcelain parts and metal accessories such as steel feet, iron caps, flanges, etc., glued together with adhesives or mechanically clamped.

[0003] In existing technologies, during circuit installation, it is usually necessary to fix wires to pin-type porcelain insulators. The current method of fixing wires typically involves manually binding and securing them to the insulators with aluminum wire. In actual operation, the stability of the wire fixation is affected by the different operating techniques of different operators, resulting in low stability. Furthermore, external factors can cause vibrations between the wire and the insulator. After prolonged use, the aluminum wire will loosen or wear, significantly reducing the stability of the wire fixation. In addition, although wire fixers for pin-type porcelain insulators have appeared on the market, existing wire fixers usually include multiple pressure plates and fastening bolts. By placing the wire between two pressure plates and then tightening it with the fastening bolts, the wire is fixed to the pin-type porcelain insulator. In actual use, disassembly and assembly are difficult, making it inconvenient for operators to conduct regular inspections and maintenance. Therefore, there is an urgent need for improvement. Utility Model Content

[0004] This application addresses the problem that in existing technologies, conductors are typically fixed to needle-type porcelain insulators using manual aluminum wire bundling, where the stability of the fixation is often affected by the operator's bundling technique. In actual use, the fixation stability is low and easily affected by environmental factors. Severe weather will accelerate the aging of the aluminum wire, thereby reducing the lifespan of the conductor. Furthermore, existing conductor fixing devices have complex structures, are difficult to disassemble and assemble, and are inconvenient for operators to conduct regular inspections and maintenance. Therefore, this application proposes a conductor tensioning and fixing device.

[0005] This application adopts the following solution: a wire tensioning and fixing device, including a fixing seat matched on a needle-type ceramic insulator, and a clamping mechanism disposed above the fixing seat. The fixing seat is used for detachable connection with the needle-type ceramic insulator, and the clamping mechanism is used for clamping the cable. The clamping mechanism includes a clamping base disposed on the fixing seat and a pressure block disposed on the clamping base. The cable can be clamped between the clamping base and the pressure block. The clamping base and the pressure block are made of elastic material.

[0006] In some possible embodiments, the clamping base includes a main body and a first clamping groove provided on the main body, into which a cable can be inserted. When the cable is inserted into the first clamping groove, the pressure block can be inserted into the first clamping groove to clamp the cable between the clamping base and the pressure block.

[0007] In some possible embodiments, the pressure block includes a block body and a second clamping groove provided on the block body. The first clamping groove and the second clamping groove together form a clamping hole for clamping a cable. When the cable is inserted into the first clamping groove, the pressure block can be inserted into the first clamping groove. The outer periphery of the cable can simultaneously fit against the inner wall of the first clamping groove and the inner wall of the second clamping groove, so that the cable is clamped between the clamping base and the pressure block.

[0008] In some possible embodiments, the block includes an arc-shaped body, an inclined block disposed on the lower end of the arc-shaped body, and a vertical portion disposed on the upper end of the arc-shaped body. The second clamping groove is disposed on the arc-shaped body. When the cable is inserted into the first clamping groove, the inclined block can abut against the inner wall of the first clamping groove.

[0009] In some possible embodiments, the wire tensioner retainer,

[0010] Define the angle between the inclined block and the arc-shaped main body as A;

[0011] The A satisfies the following relationship: 45°≤A≤60°.

[0012] In some possible embodiments, the fixing base includes a first base body disposed on the needle-type porcelain bottle, a second base body disposed on the needle-type porcelain bottle, and a fastening component disposed between the first base body and the second base body, the fastening component being used to adjust the distance between the first base body and the second base body so that the first base body and the second base body are fixed on the needle-type porcelain bottle.

[0013] In some possible embodiments, the first base is provided with a first fixing groove, and the second base is provided with a second fixing groove. The first fixing groove and the second fixing groove together form a fixing hole, into which the needle-type porcelain bottle can be matched and extended.

[0014] In some possible embodiments, the fastening assembly includes a first fastening hole on the first seat, a second fastening hole on the second seat located at a corresponding position to the first fastening hole, and an adjusting screw that simultaneously passes through the first fastening hole and the second fastening hole. When the adjusting screw rotates relative to the first seat and / or the second seat, the first seat / second seat moves toward / away from the first seat / second seat, so that the first seat and the second seat are fixed to the needle-type ceramic bottle.

[0015] In some possible embodiments, a handheld part is provided at the end of the adjusting screw for the user to hold.
