DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1

[0025] See also Figures 1 to 5A corrosion-resistant electrical hardware comprises an upper jacket 1, a connecting ear plate 2 and a lower jacket 3. The connecting ear plate 2 is symmetrically rotatably connected to one side surface of the upper jacket 1, and the lower jacket 3 is also rotatably connected between the two connecting ear plates 2. A first T-shaped rod 15 is symmetrically inserted into the surface of the upper jacket 1, and the first T-shaped rod 15 is slidably connected to the upper jacket 1, and a first arc-shaped clamping plate 16 is fixedly connected to the bottom ends of the two first T-shaped rods 15, and a spring 14 is fixedly connected between the first arc-shaped clamping plate 16 and the upper jacket 1, and a second T-shaped rod 17 is symmetrically inserted into the surface of the lower jacket 3, and the second T-shaped rod 17 is slidably connected to the lower jacket 3, and the ends of the two second T-shaped rods 17 are fixedly connected to the second arc-shaped clamping plates 19, and the surface of the second arc-shaped clamping plate 19 is rotatably connected to an adjusting screw 18, which is inserted into the surface of the lower jacket 3 and is threadedly connected to the lower jacket 3.

[0026] The upper jacket 1 is rotatably connected to a threaded clamping rod 4 on one side away from the connecting ear plate 2, and a clamping groove 5 matched with the threaded clamping rod 4 is provided on the surface of the lower jacket 3 away from the connecting ear plate 2, and a knob 6 is threadedly sleeved on the surface of the threaded clamping rod 4.

[0027] The surfaces of the upper jacket 1 and the lower jacket 3 are both fixedly connected with rubber anti-skid pads 20 .

[0028] The surfaces of the upper jacket 1, the connecting ear plate 2 and the lower jacket 3 are all provided with acrylic waterproof coating with anti-corrosion performance.

[0029] The working principle of this embodiment is as follows: when using this type of power fitting, first place the upper jacket 1 on the surface of the cable to be clamped, and rotate the lower jacket 3 close to the upper jacket 1. At this time, rotate the threaded clamping rod 4 so that the threaded clamping rod 4 is clamped in the clamping groove 5, and then rotate the knob 6. As the knob 6 slides on the surface of the threaded clamping rod 4, until the knob 6 can no longer move, the positions of the lower jacket 3 and the upper jacket 1 are in the final fixed position (the two are horizontal to each other). Then the power personnel rotate the adjusting screw 18, and the adjusting screw 18 moves on the surface of the lower jacket 3. The movement of the adjusting screw 18 drives the second arc clamping plate 19 to gradually approach the first arc clamping plate 16. In this process, the first arc clamping plate 16 gradually squeezes the spring 14, so that the spring 14 is in a compressed state until the position of the first arc clamping plate 16 no longer moves. At this time, the cable can be firmly fixed between the second arc clamping plate 19 and the first arc clamping plate 16, thereby achieving the clamping and fixing of the cable.

[0030] By providing the rubber anti-skid pad 20 , the cable can be prevented from sliding between the first arc-shaped clamping plate 16 and the second arc-shaped clamping plate 19 during use, thereby reducing the probability of cable wear.

[0031] By applying acrylic waterproof coating, the corrosion resistance of the entire electrical fittings can be improved, thereby increasing the service life of the wire clamp fittings.

[0032] Embodiment 2

[0033] This embodiment is an improvement made on the basis of the first embodiment.

[0034] By setting the U-shaped clamping ring 8, the positioning block 9 and the fastening nut 10, during the actual installation process, the U-shaped clamping ring 8 can be sleeved on the adjacent cable surface, and then the positioning block 9 can be sleeved on the surface of the U-shaped clamping ring 8, and the fastening nut 10 can be tightened, so that the positioning block 9 can be stably clamped on the adjacent cable surface.

[0035] The surface of the inner rod 21 is symmetrically fixedly connected with a limit slider 11, the limit slider 11 is slidably connected to the outer cylinder 7, a fastening bolt 12 is inserted into the surface of the outer cylinder 7, the fastening bolt 12 is threadedly connected to the outer cylinder 7, and a smooth surface 13 is provided on the surface of the inner rod 21. The fastening bolt 12 passes through one side surface of the outer cylinder 7 and extends to the inside of the outer cylinder 7 and conflicts with the smooth surface 13.

[0036] During actual use, the user can loosen the fastening bolt 12 so that the fastening bolt 12 no longer contacts the smooth surface 13. At this time, the protruding length of the inner rod 21 in the outer tube 7 can be adjusted according to the distance between the two cables, so that the U-shaped clamp 8 and the upper and lower sleeves can be fixed to the two cables. Then, the fastening bolt 12 is tightened, so that the wire clamp hardware can be installed according to the distance between the two cables, and the application range is wide.
