Description

Technical Field

[0001] This invention relates to the field of electrical technology, and more specifically to cable anti-galling spacers. Background Technology

[0002] Multiple cables are mounted on the pole and installed in parallel on the tower. When there is wind, the cables will swing. Due to the uneven force, sometimes the distance between the cables is too small, which will cause discharge and affect the normal use of the cables. Therefore, cable anti-galloping spacers were developed. The two ends of the cable anti-galloping spacers are installed on different cables to prevent the distance between the two cables from being too small.

[0003] The cable anti-galloping spacer includes a spacer body, which includes clamps at both ends and an insulator in the middle. When in use, the clamps at both ends are clamped onto different cables to prevent the cables from galloping and becoming too close together, thus avoiding the discharge phenomenon.

[0004] During use, because the cable is coiled, it often twists and turns, especially under strong winds. In existing technology, the clamps of the cable anti-galloping spacers are fixed to the cable, meaning the clamps are integrally fixed to the cable and rigidly (non-rotatable) connected to the insulator. This causes torque to be generated at the clamp connection point, damaging the cable at that location and affecting its strength. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned shortcomings by providing a cable anti-galling spacer that can reduce damage to cables when they twist and is beneficial to cable protection.

[0006] The technical solution of the present invention is implemented as follows: a cable anti-galling spacer includes a spacer body, the spacer body including clamps at both ends and an insulator in the middle, characterized in that: the clamps include two C-shaped outer shell units and two C-shaped retaining ring units, the two C-shaped outer shell units are hinged together at one end by a first hinge shaft to form an outer shell, the outer shell has a circular cavity for accommodating the retaining ring, the two C-shaped retaining ring units are hinged together by a second hinge shaft to form a retaining ring, the retaining ring is rotatably installed inside the circular cavity of the outer shell, and a locking member is installed at the other end of the two C-shaped outer shell units.

[0007] Furthermore, the retaining ring monomer also contains a layer of rubber material.

[0008] Furthermore, the insulator comprises multiple insulator units, with a rotating ring and a rotating head mating between adjacent insulator units. This rotating ring and rotating head are a first rotating ring and a first rotating head, and the first rotating ring and the first rotating head are mating and connected. The direction of relative rotation of the first rotating ring and the first rotating head is perpendicular to the length of the insulator.

[0009] Furthermore, there is a cooperating rotating ring and rotating head between the card and the insulator. This rotating ring and rotating head are a second rotating ring and a second rotating head, and the second rotating ring and the second rotating head are connected in a cooperative manner. The direction of relative rotation of the second rotating ring and the second rotating head is perpendicular to the length of the insulator.

[0010] The beneficial effects of this invention are: such a cable anti-grace spacer can reduce the damage to the cable when the cable twists and turns, and is beneficial to the protection of the cable. Attached Figure Description

[0015] The cable anti-galloping spacer of the present invention will be further described below with reference to the embodiments.

[0016] As shown in the figure, a cable anti-galling spacer includes a spacer body, which includes clamps 1 at both ends and an insulator 2 in the middle. The clamps consist of two C-shaped housing units 11 and two C-shaped retaining ring units 12. The two C-shaped housing units are hinged together at one end by a first hinge pin 13 to form a housing. Each C-shaped housing unit has a mounting component, such as a small hole, at one end for mounting the first hinge pin. The housing has a cavity inside to accommodate the retaining ring. The two C-shaped retaining ring units are hinged together at one end by a second hinge pin 14 to form a retaining ring. Each C-shaped retaining ring unit has a mounting component, such as a small hole, at one end for mounting the second hinge pin. The retaining ring is rotatably mounted inside the cavity of the housing. A locking member 15 is installed at the other end of the two C-shaped housing units.

[0017] In the prior art, the internal mechanism of the spacer bar body does not rotate. When the mechanism is fixed to the cable, the cable and the mechanism form an "I" shape. During strong winds, the cable often rotates, for example... Figure 3 In F1, the direction the cable twists is the same direction the wind blows. Because the cable is clamped in the clip, it is often damaged at the part of the clip that is fixed in place.

[0018] Because this invention adopts the above-mentioned improved technical solution, that is, the cable can be rotatably installed in the clamp, even in strong winds, the cable can be rotatably installed in the clamp, that is, the direction of cable rotation is as follows: Figure 3 The direction of F1 will not damage the cable, thus enabling the implementation of the purpose of this invention.

[0019] The retaining ring can be rotatably installed inside the circular cavity of the housing. For example, the outer periphery of the retaining ring and the inside of the housing have a mating annular groove 51 and a rotating block 52 installed in the groove, respectively.

[0020] When the two C-shaped retaining rings are open, the cable 4 can be placed in the recess of one retaining ring. Then, the two C-shaped retaining rings are closed to form a retaining ring. At this time, the two C-shaped outer shells 11 are in the open state, and the retaining ring is installed in the recess of one C-shaped outer shell 11. The two C-shaped outer shells 11 wrap around the retaining ring. The other ends of the two C-shaped outer shells are locked with a locking device, so that the cable can rotate inside the shell.

[0021] The locking components mentioned include, for example, various latches in the prior art, or any other components that can fix the other end of the two C-shaped housing units together.

[0022] The insulator has a retaining ring unit connected to a clamp on its left side, and another retaining ring unit connected to the insulator on its right side.

[0023] As a major contribution of this invention, the applicant has discovered that when a cable twists in the wind, damage is caused to the cable by using cable anti-galling spacers of the prior art, i.e., damage is caused to the cable by clamps locking the cable.

[0024] exist Figure 1 In the diagram, the left-hand locking mechanism is shown as follows: a schematic diagram of the two C-shaped outer shell units 11 and the two C-shaped retaining ring units when open; the right-hand locking mechanism is shown as follows: a schematic diagram of the two C-shaped outer shell units 11 and the two C-shaped retaining ring units when closed, with the retaining rings inside the circular cavity of the outer shell, meaning that the retaining rings can be rotatably installed inside the circular cavity of the outer shell.

[0025] Furthermore, the retaining ring monomer also contains a layer of rubber material 3 inside.

[0026] Specifically, there is an additional layer of rubber material 3 inside the two C-shaped retaining rings.

[0027] This design also provides the advantage of a more secure cable clamping mechanism.

[0028] Furthermore, the insulator comprises multiple insulator units, with a rotating ring and a rotating head mating between adjacent insulator units. This rotating ring and rotating head are a first rotating ring 21 and a first rotating head 22, and the first rotating ring and the first rotating head are mating and connected. The direction of relative rotation of the first rotating ring and the first rotating head is perpendicular to the length of the insulator.

[0029] This invention is configured to resist the effects of the two connected cables, such as... Figure 3 The damage to the cable caused by the twisting in the F2 direction. The direction of relative rotation between the first rotating ring 21 and the first rotating head 22 is as follows: Figure 1 As shown in F3.

[0030] Furthermore, the card and the insulator are connected by a rotating ring and a rotating head, which are a second rotating ring 23 and a second rotating head 16. The second rotating ring and the second rotating head are connected in a cooperative manner, and the direction of relative rotation of the second rotating ring and the second rotating head is perpendicular to the length of the insulator.

[0031] The relative rotation direction of the second rotating ring and the second rotating head is as follows: Figure 1 As shown in F4.

[0032] This invention is configured to resist the effects of the two connected cables, such as... Figure 3 The damage to the cable caused by twisting in the F2 direction.

[0033] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
