Description

Technical Field

[0001] The invention relates to the technical field of insulator clamps, and in particular to an insulator clamp with a locking structure. Background Art

[0002] In the power transmission and distribution system, insulators play a vital role. They are not only the indispensable supporting and fixing components of the transmission line, but also the key to ensure the stable transmission of electric energy. The traditional insulator fixture design often relies on some relatively basic mechanical structures to achieve the fastening and binding of cables. However, these traditional fixing methods that have been used for many years have gradually exposed some shortcomings and limitations that cannot be ignored in practical applications.

[0003] The primary problem is that the stability of the fixing effect is obviously insufficient. Limited by the relatively simple design of traditional clamps and the lack of complex mechanisms, the cables are very likely to become loose or displaced after being tested by natural environments such as wind, sun, rain, frost, etc. for a long time. Especially when encountering extremely harsh weather conditions, such as strong winds and heavy rains, the external forces on the cables will be significantly enhanced, which is undoubtedly a severe challenge to the fixing ability of traditional clamps. In such a situation, the fixing effect of the cable is often greatly reduced, or even completely ineffective, resulting in serious consequences such as the cable falling off or breaking during power transmission.

[0004] Unstable fixation will not only reduce the service life of the cable, but also pose a major threat to the safe and stable operation of the entire power system. Once the cable falls off or breaks due to failure of fixation, it will directly lead to power transmission interruption, affecting the normal power demand of the majority of users. In serious cases, it may also trigger a series of chain reactions, such as equipment damage, power outages, etc., causing immeasurable losses to social and economic life. It can be seen that the existing technology still needs to be improved and enhanced.

The locking through hole 5 is arranged with a connecting section 501 and a positioning section 502 from the outside to the inside, and a connecting thread 601 and a positioning thread 602 are arranged in sequence on the rod of the locking bolt 6. The connecting section 501 is provided with an internal thread matched with the connecting thread 601, and the positioning thread 602 extends into the locking cylinder 7 and is connected with the internal thread on the inner wall of the locking cylinder 7. The outer wall of the locking cylinder 7 is provided with the guiding ridge 702, and the guiding groove is opened on the inner wall of the locking through hole 5 along the axial direction of the locking through hole 5. The end of the locking cylinder 7 away from the locking bolt 6 is provided with the wedge groove 701, and the wedge groove 701 is clamped at the thread of the fastening bolt 3 to form a lock.

[0029] In this embodiment, the locking through hole 5 also includes an operating section 503, and the operating section 503 is arranged on the outside of the connecting section 501. The head of the locking bolt 6 is located in the operating section 503. It can be understood that the setting of the operating section 503 makes the head of the locking bolt 6 located in an easy-to-operate position, which facilitates the locking operation. At the same time, the operating section 503 can block the contact between the outside and the head of the locking bolt 6, further ensuring the locking effect.

[0030] Preferably, it further includes anti-skid ribs, which are arranged on the surface of the positioning groove and arranged along the length direction of the positioning groove. The provision of the anti-skid ribs significantly improves the fixing effect of the positioning groove on the cable, and is arranged along the length direction of the positioning groove, which increases the friction between the cable and the cable, thereby effectively preventing the cable from sliding during use. In more detail, the insulating gasket 1 is also provided with reinforcing ribs, which have the same direction as the anti-skid ribs, and the reinforcing ribs are provided on opposite sides of the fastening boss 2.

Optionally, the thickness of the first connecting portion 402 and the second connecting portion 403 is 0.3-0.5 times the thickness of the first arc-shaped body 401.

[0033] In more detail, the second arc-shaped arm 41 includes a second arc-shaped body 411, a third connecting portion 412 and a fourth connecting portion 413, the third connecting portion 412 and the fourth connecting portion 413 are respectively provided at both ends of the second arc-shaped body 411, the third connecting portion 412 is flush with the upper surface of the first arc-shaped body 401, and the fourth connecting portion 413 is flush with the lower surface of the second arc-shaped body 411, the thickness of the second arc-shaped body 411 is greater than the third connecting portion 412 and the fourth connecting portion 413, the third connecting portion 412 and the fourth connecting portion 413 are provided with the arc-shaped opening 42, the direction of the arc-shaped opening 42 is perpendicular to the direction of the fastening boss 2, and the arc-shaped opening 42 provided on the third connecting portion 412 and the fourth connecting portion 413 is horizontally arranged; optionally, the thickness of the third connecting portion 412 and the fourth connecting portion 413 is 0.3-0.5 times the thickness of the second arc-shaped body 411.

[0034] In this embodiment, the thickness of the first connecting portion 402 and the second connecting portion 403 is half of the thickness of the first arc-shaped body 401, and the thickness of the third connecting portion 412 and the fourth connecting portion 413 is half of the thickness of the second arc-shaped body 411.

Aluminum alloy has the characteristics of light weight, high strength, good corrosion resistance, easy processing and good conductivity. Polymer insulating materials are used to isolate charged or different potential conductors. In aluminum alloy mechanical structures, polymer insulating materials are often used as electrical insulating layers to prevent current leakage or short circuit. By casting or coating polymer insulating materials on aluminum alloy parts, a strong and insulating protective layer can be formed to improve the electrical safety and reliability of the equipment.

The outer cover body 8 is composed of polymer materials such as polyethylene (PE) and polyvinyl chloride (PVC), and has the characteristics of good insulation performance, light weight, and easy processing. It is suitable for occasions with electrical insulation and lightweight requirements. The size and shape of the outer cover body 8 should match the insulating gasket 1 to ensure that it can be tightly covered on the insulating gasket 1 and the fixing bolt, and will not interfere with its function. Therefore, the outer cover body 8 can effectively protect the insulating gasket 1 from mechanical damage, corrosion and pollution, and extend its service life.
