Description

Technical Field

[0001] The present invention relates to the technical field of power applications, and particularly relates to a cable terminal support and fixator. Background Art

[0002] The length of the cable terminal will vary according to the installation position of the cable terminal, the cable model, and the type of connecting device.

[0003] In the operation and management of the power grid, we found that in many cases, the insulating straight pipe in the cable terminal accessories does not match the actual required length, and most of them need to be lengthened. However, if the insulating straight pipe of the cable is increased too long, the cable core will swing with the wind, and the core will cause fine cracks in the insulating layer of the cable during the process of dancing with the wind. These fine cracks will be broken down by the uneven electric field over time, resulting in insulation damage. Therefore, the present invention proposes a cable terminal support and fixator to solve the problems existing in the prior art. Summary of the Invention

[0004] In view of the above problems, the present invention proposes a cable terminal support and fixator. The cable terminal support and fixator is sleeved on the insulating straight pipe in the cable terminal accessories through a fixing component. By tightening the first insulating screw, the fixing component is closely attached to the insulating straight pipe. Through the cooperation of the support rod and the tension support rod with the connector, a stable support effect is achieved, and the length of the support rod inserted into the connector can be adjusted arbitrarily according to the on-site installation situation, better adapting to the installation position.

[0005] To achieve the purpose of the present invention, the present invention is realized through the following technical solutions: A cable terminal support and fixator includes a fixing component and a connecting component. The fixing component is sleeved on the cable terminal insulating straight pipe, and multiple groups of the fixing components are provided. A connecting component is connected between adjacent two groups of the fixing components. The connecting component includes a connector, a support rod, and a tension support rod. Two groups of the support rod and the tension support rod are provided. One ends of the two groups of the support rods are clamped in the connector respectively. The two groups of the tension support rods are respectively connected to the outer ends of the two groups of the support rods. The outer ends of the two groups of the tension support rods are respectively connected to the adjacent two groups of the fixing components. The fixing component is a hollow cylinder. The fixing component includes a semi-circular column and a locking piece. Two groups of the semi-circular columns are provided in a matching manner. Locking pieces are provided at both ends of the two groups of the semi-circular columns. First screw holes are provided on the locking pieces. The locking pieces on the two groups of the semi-circular columns are fixed through the first screw holes in cooperation with the first insulating screw. The connector is composed of two groups of matching blocks. An arc-shaped card slot is provided inside the block. Two groups of the arc-shaped card slots are provided. Second screw holes are provided at the upper and lower ends inside the two groups of the blocks. The two groups of the blocks are fixed through the second screw holes in cooperation with the second insulating screw.

[0006] A further improvement lies in that: a resilient filling piece is provided inside the side wall of the semi-cylindrical column, and at least three groups of resilient filling pieces are provided. A reinforcing block is provided inside the resilient filling piece, and multiple groups of reinforcing blocks are provided.

[0007] A further improvement lies in that: friction protrusions are provided inside the arc-shaped card slot, and multiple groups of friction protrusions are provided. A notch is provided in the arc-shaped card slot between two adjacent groups of friction protrusions, and a ball is rotatably installed inside the notch. A spring is connected between the inner side of the ball and the inner side of the notch.

[0008] A further improvement lies in that: the fixing component is made of insulating epoxy resin, and the length of the fixing component 1 is 35 - 45 mm. The inner diameter of the fixing component is adapted to the cable model.

[0009] A further improvement lies in that: the tension support rod is in the shape of an "S", and the tension support rod has elastic deformation. The tension support rod offsets the lateral force caused by the wind sway of the cable through elastic deformation.

[0010] A further improvement lies in that: the connector, the support rod, and the tension support rod are all made of insulating epoxy resin. The support rod is a cylindrical shape with a diameter of 8 - 12 mm.

[0011] The beneficial effects of the present invention are as follows: In the present invention, the fixing component is sleeved on the insulating straight pipe in the cable terminal accessory. By tightening the first insulating screw, the fixing component is closely attached to the insulating straight pipe. Through the cooperation of the support rod and the tension support rod with the connector, a stable support effect is achieved. Moreover, the length of the support rod inserted into the connector can be arbitrarily adjusted according to the on-site installation situation, better adapting to the installation position. At the same time, through the elastic deformation of the "S"-shaped tension support rod, the lateral force caused by the wind sway is offset to achieve an anti-vibration effect, reducing the cracking of the cable insulation layer caused by the cable core dancing with the wind. In summary, the installation is convenient, the fixing effect is good, the anti-vibration effect is obvious, and the whole is made of insulating epoxy resin, which can effectively prevent the formation of magnetic flux circulation from damaging the insulation layer of the cable.

Specific implementation manner

[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0019] According to Figure 1 、 2 、3, 4, and 5 as shown, this embodiment proposes a cable terminal head support and fixator, including a fixed component 1 and a connection component. The fixed component 1 is sleeved on the insulating straight pipe of the cable terminal, and multiple groups of the fixed component 1 are provided. A connection component is connected between adjacent two groups of the fixed component 1. The connection component includes a connector 2, a support rod 3, and a tension support rod 4. Two groups of the support rod 3 and the tension support rod 4 are provided. One ends of the two groups of the support rod 3 are respectively clamped in the connector 2. The two groups of the tension support rod 4 are respectively connected to the outer ends of the two groups of the support rod 3. The outer ends of the two groups of the tension support rod 4 are respectively connected to the adjacent two groups of the fixed component 1. The fixed component 1 is a hollow cylinder. The fixed component 1 includes a semi-circular column 5 and a locking piece 6. Two groups of the semi-circular column 5 that are adapted to each other are provided. Locking pieces 6 are provided at both ends of the two groups of the semi-circular column 5. First screw holes 7 are provided on the locking pieces 6. The locking pieces 6 on the two groups of the semi-circular column 5 are fixed through the cooperation of the first screw holes 7 and the first insulating screws 8. The connector 2 is composed of two groups of adapted blocks 9. An arc-shaped card slot 10 is provided on the inner side of the block 9. Two groups of the arc-shaped card slot 10 are provided. Second screw holes 11 are provided at the upper and lower ends inside the two groups of the block 9. The two groups of the block 9 are fixed through the cooperation of the second screw holes 11 and the second insulating screws 12. When in use, the fixed component 1 is sleeved on the insulating straight pipe in the cable terminal accessory, and the first insulating screw 8 is tightened to make the fixed component 1 fit tightly with the insulating straight pipe. Then, the length of the support rod 3 clamped in the connector 2 can be adjusted arbitrarily according to the on-site installation situation, so as to adjust the length of the connection component and stably support.

[0020] A toughness filling piece 13 is provided inside the side wall of the semi-circular column 5, and at least three groups of the toughness filling piece 13 are provided. A reinforcing block 14 is provided inside the toughness filling piece 13, and multiple groups of the reinforcing block 14 are provided. The two groups of the semi-circular column 5 are fixed on the insulating straight pipe through the cooperation of the first screw holes 7 on the locking pieces 6 and the first insulating screws 8. The toughness filling piece 13 and the reinforcing block 14 are used to make the semi-circular column 5 more firm when being clamped.

[0021] The inner side of the arc-shaped card slot 10 is provided with friction protrusions 15, and there are multiple groups of friction protrusions 15. In the arc-shaped card slot 10 between adjacent two groups of the friction protrusions 15, a notch 16 is provided, and a ball 17 is rotatably installed inside the notch 16. A spring 18 is connected between the inner side of the ball 17 and the inner side of the notch 16. When adjusting the length of the adjusting support rod 3 inserted into the connector 2, loosen the second insulating screw 12, and the ball 17 bounces under the action of the spring 18, and the support rod 3 will not be damaged by friction when moving in the arc-shaped card slot 10. When fixing, tighten the second insulating screw 12 to make the two clamping blocks 9 close, and the ball 17 is pressed into the inner side of the notch 16. At this time, the friction protrusion 15 contacts the support rod 3 and will not slip.

[0022] The fixing component 1 is made of insulating epoxy resin, and the length of the fixing component 1 is 40 mm. The inner diameter of the fixing component 1 is adapted to the cable model. It can protect the insulating layer of the cable straight pipe and will not form scratches or hidden damages to the whole during the sleeving process.

[0023] The shape of the tension support rod 4 is S-shaped, and the tension support rod 4 has elastic deformation. The tension support rod 4 cancels out the lateral acting force of the cable swaying due to the wind through elastic deformation. It reduces the cracking of the cable insulating layer caused by the cable core dancing with the wind.

[0024] The connector 2, the support rod 3 and the tension support rod 4 are all made of insulating epoxy resin, which can effectively prevent the magnetic flux from forming a circulating current and damaging the insulating layer of the cable. The support rod 3 is a cylindrical shape with a diameter of 10 mm.

[0025] The cable terminal head support and fixator is sleeved on the insulating straight pipe in the cable terminal accessory through the fixing component 1. The fixing component 1 is tightly attached to the insulating straight pipe by tightening the first insulating screw 8. The support rod 3 and the tension support rod 4 cooperate with the connection of the connector 2 to achieve the effect of stable support. Moreover, the length of the support rod 3 inserted into the connector 2 can be adjusted arbitrarily according to the on-site installation situation to better adapt to the installation position. At the same time, the elastic deformation of the "S"-shaped tension support rod 4 cancels out the lateral acting force of the wind sway to achieve the anti-vibration effect and reduce the cracking of the cable insulating layer caused by the cable core dancing with the wind. To sum up, it is convenient to install, has a good fixing effect, an obvious anti-vibration effect, and is made of insulating epoxy resin as a whole, which can effectively prevent the magnetic flux from forming a circulating current and damaging the insulating layer of the cable.
