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 spacer 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, cables may experience arcing, meaning they move along their length. Multiple cables connected by cable anti-galling spacers may exhibit uneven arcing. In existing technology, the clamps of the cable anti-galling spacers are fixed to the cables as a single unit. This means that while the cable anti-galling spacers restrict the arcing of the cables, they can damage the cables when the arcing force is large, which is not conducive to protecting the cables. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned shortcomings by providing a cable anti-galloping spacer that is beneficial for protecting cables when they are jerking unevenly—a cable anti-galloping spacer with a sleeve.

[0006] The technical solution of this invention is implemented as follows: a cable anti-galloping spacer with a sleeve rod, comprising a spacer rod body, wherein the spacer rod body includes clamps at both ends and an insulator in the middle, wherein the clamps are components that connect the cable and the insulator, characterized in that: the clamp ends have outer retaining rings; it also includes a sleeve rod installed on the cable, wherein the sleeve rod comprises two sleeve rod parts, the cross-section of the sleeve rod parts is an arc-shaped structure, the sleeve rod parts have recesses inside, and the sleeve rod parts have screw holes. During assembly, the recesses of the two sleeve rod parts face each other to form a sleeve rod hollow core for accommodating the cable, and screws are inserted into the screw holes to connect the two sleeve rod parts and form a sleeve rod, wherein a slide rail for accommodating the retaining ring is formed in the middle of the outer side of the sleeve rod, and the retaining ring is on the slide rail outside the sleeve rod; there are limiting protrusions at both ends of the sleeve rod, the limiting protrusions being components that prevent the retaining ring from sliding out.

[0007] Furthermore, the sleeve rods are in pairs. In use, the two sleeve rods are installed on two different cables respectively. Each clamp has a retaining ring, and the two retaining rings are respectively on the slide rails of the two sleeve rods.

[0008] Furthermore, it also includes a spring, one end of which is connected to the end of the sleeve rod, and the other end of which is connected to the retaining ring.

[0009] Furthermore, the hollow sleeve core has flared openings at both ends.

[0010] Furthermore, the hollow core of the sleeve also contains a rubber layer.

[0011] The beneficial effect of this invention is that such a cable anti-galling spacer has the advantage of protecting the cable when the cable is jerking unevenly. Attached Figure Description

[0016] The cable anti-galloping spacer with sleeve of the present invention will be further described below with reference to the embodiments.

[0017] As shown in the figure, a cable anti-galling spacer with a sleeve includes a spacer body 1, which includes clamps 2 at both ends and an insulator 3 in the middle. The clamps are components that connect the cable and the insulator. The clamps are characterized by having an outer retaining ring 21 at the end of each clamp. It also includes a sleeve 4 installed on the cable. The sleeve 4 includes two sleeve body parts 41. The cross-section of each sleeve body part is an arc-shaped structure. Each sleeve body part has a notch 42 inside and a screw hole 43 on it. During assembly, the notches of the two sleeve body parts face each other to form a sleeve core that accommodates the cable. Screws 44 are inserted into the screw holes to connect the two sleeve body parts and form a sleeve. A slide rail 45 is formed in the middle of the outside of the sleeve 41 to accommodate the retaining ring. The retaining ring is located on the slide rail outside the sleeve 41. There are limiting protrusions 46 at both ends of the sleeve 41. The limiting protrusions are components that prevent the retaining ring from sliding out.

[0018] With the above-described configuration of this invention, when the two connected cables move unevenly, the spacer bar body can slide relative to each other on the slide rail. Figure 1 , 3 The direction of the middle arrow F is the direction of sliding, which can prevent the cable from being twisted and achieve the purpose of this invention.

[0019] In one embodiment, the length of the slide is 1-1.5 meters.

[0020] In one embodiment, the length of the spacer body is 4 to 5 times the length of the slide.

[0021] Furthermore, the sleeve rods are in pairs. In use, the two sleeve rods are installed on two different cables respectively. Each clamp has a retaining ring, and the two retaining rings are respectively on the slide rails of the two sleeve rods.

[0022] This invention also has the advantage that both ends of the spacer bar can slide relative to each other, resulting in better performance.

[0023] Furthermore, it also includes a spring 5, one end of which is connected to the end of the sleeve rod, and the other end of which is connected to the retaining ring.

[0024] This invention also has the advantage that the more effort is required for the retaining ring to slide towards the end of the slide, the more effort is required. Under normal circumstances, the retaining ring is located in the middle of the slide, which can resist the cable shaking caused by strong winds.

[0025] Furthermore, the hollow sleeve core has flared openings 47 at both ends.

[0026] This design also has the advantage of better protecting the cable and preventing damage to the cable at the end of the sleeve.

[0027] Furthermore, the hollow core of the sleeve also contains a rubber layer 6.

[0028] This design also provides the advantage of better cable protection.

[0029] 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.
