Description

TECHNICAL FIELD

[0001] The utility model relates to power auxiliary equipment technical field, specifically, relate to a cable terminal lead curvature adjuster. BACKGROUND

[0002] For the cable terminal, the general requirement when installing is that three-phase lead lines need to be perpendicular to the busbar, achieving neatness and beauty. Especially for the power distribution cabinet using cable T-type separable connector for electrical connection, if the three-phase lead lines are not perpendicular to the power distribution cabinet busbar porcelain sleeve, it may cause the three-phase T-type separable connector tail end adapter to be too close, thereby causing inter-phase discharge at the adapter position and leading to breakdown. Therefore, it is required that the cable A and C phases have a certain curvature when installing, which can ensure that the cable A and C phase T-type separable connector tail end adapters maintain a safe distance from the B phase T-type separable connector tail end adapter, and also ensure that the cable A and C phase T-type separable connectors are installed vertically and aesthetically.

[0003] The original cable T-type separable connector installation requires adjustment of the A and C phase lead line curvature. For small cross-section cables, manual adjustment is generally used. For large cross-section cables, the commonly used method on site is to use a crowbar (steel or wood) as an auxiliary tool, and then manually adjust the curvature. This method can easily cause the following problems: first, the point contact between the crowbar and the cable can cause damage to the cable main insulation if the manual adjustment force is too large; second, due to the limitation of the support points in the cabinet, the deflection is difficult to control, and the adjusted lead line curvature position is often located at the adapter installation position, causing the adapter to be unable to tightly fit with the cable after installation, resulting in a gap that causes discharge.

[0025] In combination with Figures 1 to 9 the drawings, the present embodiment provides a cable terminal lead arc adjuster, which comprises a support, two rollers 1 are rotatably arranged on the support, a pressing claw 2 is rotatably arranged between the two rollers 1, and a space suitable for placing a cable is formed between the pressing claw 2 and the two rollers 1; the pressing claw 2 is connected with a piston joint 6 suitable for being connected with a hydraulic jack through a chain plate 5, and when the hydraulic jack acts on the piston joint 6, the piston joint 6 is suitable for driving the pressing claw 2 to rotate through the chain plate 5 to provide a bending force to the cable placed between the pressing claw 2 and the two rollers 1, thereby adjusting the arc of the cable.

[0026] In combination with Figures 1 to 9As shown, the support frame comprises two side plates 3 and side blocks 4 connecting the two side plates 3, and the two rollers 1 are arranged on the side plates 3 respectively. A fixed shaft is arranged on the two side plates 3, and the pressing jaw 2 is rotatably arranged on the fixed shaft. Here, the fixed shaft is a hexagonal shaft. The two ends of the fixed shaft extend out of the two side plates 3 respectively, and a wheel jaw 9 for mounting the roller 1 is arranged at each end of the fixed shaft. The roller 1 is rotatably mounted on the wheel jaw 9. A hexagonal slot is arranged on the side plate 3 for the hexagonal shaft to pass through, and the hexagonal shaft is fixed to prevent it from rotating. The middle part of the hexagonal shaft is an optical shaft for hinging the pressing jaw 2, so that the pressing jaw 2 can rotate on the hexagonal shaft. A hexagonal slot matching the hexagonal shaft is arranged on the wheel jaw 9 to fix the roller 1 on the hexagonal shaft. The hexagonal shaft passes through the wheel jaw 9 and is fixed by a blocking gasket 8 to prevent the wheel jaw 9 from being separated from the hexagonal shaft. In addition, an adjusting screw 10 can be detachably arranged on the wheel jaw 9. The adjusting screw 10 is adapted to pass through the wheel jaw 9 to fix the wheel jaw 9 on the hexagonal shaft. The adjusting screw 10 can assist the fixation of the wheel jaw 9 and prevent the wheel jaw 9 from shaking.

[0027] In this embodiment, the pressing jaw 2 is arranged in an arc shape, and the arc surface faces one side of the roller 1. Therefore, when the cable is pressed and bent, the damage to the surface of the cable can be reduced by face contact because the cable is generally cylindrical. Similarly, the roller 1 is provided with an inwardly recessed arc portion, which can adapt to the cable and prevent damage, and also prevent the cable from being separated when the cable is pressed and bent on the roller 1.

[0028] In operation, the piston joint 6 is used to connect with an external hydraulic jack. The piston joint 6 is hinged at one end of the chain plate 5, and the other end of the chain plate 5 is connected with the bottom of the pressing jaw 2. Therefore, when the hydraulic jack is lifted, the chain plate 5 is driven to rise, and then the pressing jaw 2 is driven to rotate around the fixed shaft, so as to convert the hydraulic lifting force into the pressing and bending force of the pressing jaw 2 on the cable. By this device, linear motion can be converted into rotary motion, and linear driving can save a large space requirement, so it is also suitable for narrow space. In addition, the roller 1 is movable, and when the cable arc is adjusted, the roller 1 is rolled in with the cable, which can effectively prevent the cable from being pulled.

[0029] It should be understood that the above is only a preferred embodiment of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solution falling within the concept of the present application belongs to the protection scope of the present application.

[0030] The above introduction of the drawings used in the embodiments only shows some embodiments of the utility model, and should not be regarded as limitation to the scope.
