Description

Technical Field

[0001] This utility model relates to the field of cable branch box technology, and specifically provides an insulating support structure for the base of a cable branch box. Background Technology

[0002] Cable distribution boxes are enclosed devices used in power distribution lines to connect cables to each other or cables to other electrical equipment. They are characterized by full insulation, full enclosure, corrosion resistance, and maintenance-free operation. They can realize functions such as cable splitting, branching, transfer, circuit control, and protection. They can split the main trunk cable into multiple smaller cables to meet the power supply needs of different loads. They can provide transfer when the cable length is insufficient or there are too many joints, improving line safety. They can be equipped with secondary equipment such as fuses, knife switches, and indicator lights to realize overcurrent, short circuit, and grounding protection. Distribution boxes with switches or circuit breakers can also realize functions such as switching, remote control, and automation.

[0003] Insulating supports are important connecting components of cable branch box bases. Common forms of insulating supports are insulating columns or insulating brackets. These supports use high-strength insulating materials (such as epoxy resin, composite insulators, or ceramics) to support busbars and branch boxes while also achieving electrical isolation. Existing base plate insulating supports are not simple enough in layout, have limited support strength, and poor end insulation. Therefore, it is necessary to design the structure of insulating supports in branch boxes to ensure neat cable arrangement and support protection on the base, improve the arc insulation of busbars, and improve the overall service life and safety of the product.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following description is provided in conjunction with the appendix. Figure 1-5 The present invention will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and do not constitute a limitation thereof.

[0019] An insulating support structure for a cable branch box base includes a support plate body 1 placed on the base and arc-insulating plates 2 evenly distributed at both ends of the support plate body 1. The arc-insulating plates 2 are used to isolate the busbar from the outside of the support plate body 1, which can greatly improve the insulation performance. At the same time, the two ends of the busbar can be close to the arc-insulating plates 2, and the arc-insulating plates 2 can also support the busbar. The arc-insulating plates 2 are provided with wire-passing holes 3. When it is necessary to connect wires from the busbar, the connecting wires can be bolted to the busbar and then the connecting wires can be directly passed through the wire-passing holes 3. The operation is simple, the required connecting wires are short, and it will not cause internal winding.

[0020] The support plate body 1 includes Figure 1 The diagram shows a busbar receiving area 4 and reinforcing support areas 5 located on both sides of the busbar receiving area 4. The busbar is installed within the busbar receiving area 4, and the width of the arc-insulating plate 2 is not less than the width of the busbar to provide better arc-insulating effect for the busbar. Figure 1 , Figure 2 As shown, the arc-insulating plate 2 is an isosceles trapezoidal plate with the width of the upper plate 6 being smaller than that of the lower plate 7. The upper plate 6 and the lower plate 7 are connected by a waist plate 8. The arc-insulating plate 2 with the isosceles trapezoidal structure has better support strength. A reinforcing plate 9 is provided in the middle and lower part of the waist plate 8. The outer wall of the reinforcing plate 9 is coplanar with the outer wall of the waist plate 8. The reinforcing plate can better support the arc-insulating plate 2 and improve the overall strength of the support plate body 1. The width of the arc-insulating plate 2 between the reinforcing plates 9 is not less than the width of the busbar to ensure insulation capacity.

[0021] A limiting plate 10 is connected between the symmetrical reinforcing plates 9 on both ends of the arc-insulating plate 2. The limiting plate 10 is located on the upper end of the support plate body 1, and a busbar receiving area 4 is formed between the limiting plate 10 and the arc-insulating plate 2. When a rectangular busbar is used, the rectangular busbar is placed within the busbar receiving area 4, and usually does not fill the entire busbar receiving area 4. When the busbar used is... Figure 4 When the T-shaped busbar shown is installed, part A of the T-shaped busbar can be accommodated between the limiting plates 10, and part B can be locked in the busbar locking groove above. The limiting plates 10 can install and limit the T-shaped busbar. This insulation support structure has strong versatility. At the same time, the busbar accommodating area 4 can also facilitate ventilation and heat dissipation.

[0022] Multiple connecting strips 11 are evenly arranged on the upper end of the support plate body 1, which are connected to the limiting plates 10. The connecting strips 11 are perpendicular to the limiting plates 10 and parallel to the arc-insulating plate 2. The height of the connecting strips 11 is less than the height of the limiting plates 10. The connecting strips 11 can support the busbar, raise the busbar, and leave a heat dissipation gap between the busbar and the support plate body 1, thereby improving ventilation and heat dissipation performance and increasing the overall service life of the product.

[0023] like Figure 1-3 As shown, the wire hole 3 is located at the lower part of the arc insulation plate 2 and between the reinforcing plates 9. The wire hole 3 is provided on both ends of the arc insulation plate 2 or on one of the arc insulation plates 2. In this embodiment, the wire hole 3 is provided on one arc insulation plate 2, which is used for scenarios where only one end of the base needs to be connected to the wire. Alternatively, depending on the actual situation, wire holes 3 can be opened on both arc insulation plates 2. At the same time, there are two wire holes 3 on one arc insulation plate 2. The two wire holes 3 are set close to the reinforcing plate 9 to facilitate wire exit and avoid interference.

[0024] The reinforcing plate 9 is a tapered plate structure with an inner diameter that gradually decreases from top to bottom. This structure can further improve the support performance of the reinforcing plate 9. The reinforcing support area 5 is located outside the limiting plate 10. The reinforcing support area 5 includes an outer end support platform 12 that is parallel to the limiting plate 10. The outer wall of the outer end support platform 12 is coplanar with the outer wall of the support plate body 1. The height of the outer end support platform 12 is less than the height of the limiting plate 10. While providing reinforcing support, it can form a height difference with the limiting plate 10 for better ventilation and heat dissipation. A heat dissipation area 13 is formed between the outer end support platform 12 and the limiting plate 10, which can further improve heat dissipation performance while ensuring strength.

[0025] When using, such as Figure 5 As shown, Figure 5 A represents the busbar, B represents the insulating pressure plate, and C represents the base. The support plate body 1 is located on the upper end of the base, and the busbar is located in the middle of the support plate body 1 and is parallel to the support plate body. The busbar is pressed onto the support plate body 1 by the insulating pressure plate.
