Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable connection technology, and in particular to a connector. Background Technology
[0002] When laying cables, it is often necessary to connect two or more cables. This connection is often made by direct connection followed by insulation. However, this method affects the connection strength, electrical connection effectiveness, and insulation performance. Furthermore, the deterioration of insulation often leads to overheating at the connection point, thus impacting the power system. Utility Model Content
[0003] This utility model provides a connector to overcome the shortcomings of the prior art, solving the problems of poor insulation and weak connection strength, and has strong practicality.
[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:
[0005] A connector includes a rectangular block with multiple through holes at both ends. Each through hole has a circular groove at both ends, with an injection hole connected to the groove. A spherical groove is located in the middle of each through hole, with a through hole connected to the groove. Wires pass through the through holes, and the connection point of two wires is located at the spherical groove. The spherical groove is filled with a conductive filler, and the circular groove is filled with adhesive, which adheres to the outer layer of the wires. During connection, the exposed sections of the cables are twisted together in the spherical groove and welded at the joint using hot-melt solder. The resulting spherical structure becomes the main load-bearing component, thereby enhancing the connection strength between the cables. The circular groove not only secures the cables with adhesive but also seals them to prevent affecting the insulation of the connection. The rectangular block is made of a material with insulating and high-strength properties.
[0006] Furthermore, in order to facilitate cable splicing operations and to perform insulation and strengthen the connection after twisting and splicing, a cutting slit is provided on the rectangular block. The cutting slit penetrates the side wall of the rectangular block and cuts the rectangular block and its connecting holes, circular grooves and spherical grooves along the height direction of the rectangular block. The through hole and the liquid injection hole are located in the upper half of the rectangular block.
[0007] Furthermore, to avoid the problem of tin overflow during the injection of hot-molten tin, multiple baffles are provided on the upper wall of the lower half of the rectangular block. The baffles are located between two adjacent spherical grooves, and multiple slots are opened on the lower wall of the upper half of the rectangular block, with the baffles passing through the slots.
[0008] Furthermore, in order to improve the strength and insulation effect of the rectangular blocks, they are made of ceramic.
[0009] Furthermore, in order to facilitate the injection of hot-melt solder, an upper extension ring is provided in the upper half of the rectangular block and concentric with the through hole.
[0010] Furthermore, to facilitate the injection of hot-melt solder, the upper end of the through hole is tapered, and the lower end of the tapered structure is the smaller end.
[0011] Furthermore, in order to improve the insulation effect, an inner rod is inserted through the through hole, and an end cap is provided at the upper end of the inner rod. The lower end of the end cap is connected to the upper extension ring by a thread to seal the through hole.
[0012] Furthermore, in order to fix the rectangular block, multiple screws are inserted through the rectangular block, and the two ends of the screws are connected to the first nut by threads. The inner end of the first nut acts on the upper and lower walls of the rectangular block.
[0013] Furthermore, in order to fix the cable and prevent the connection from being directly stressed when the cable is pulled, connecting plates are respectively fitted at both ends of the screw. The two ends of the screw are respectively connected to a second nut by thread. The second nut acts on the connecting plate. A clamping plate is provided at the other end of the connecting plate located at the same end. A constraint groove is opened on the inner wall of the clamping plate, and a soft buffer layer is provided on the inner wall of the constraint groove.
[0014] The advantages of the above technical solution are:
[0015] This invention improves the connection strength and insulation effect of cables after they are connected. Attached Figure Description

[0022] Figure 6A three-dimensional structural diagram of the end cap is shown. Detailed Implementation
[0023] like Figures 1-6 As shown, a connector includes a rectangular block 1 made of ceramic. Multiple connecting holes 10 are provided at both ends of the rectangular block 1. Circular grooves 11 are provided at both ends of the connecting holes 10. Liquid injection holes 14 are connected to the circular grooves 11. A spherical groove 12 is provided at the middle position of the connecting holes 10. Through holes 15 are connected to the spherical groove 12.
[0024] A rectangular block 1 has a cutting slit 100 that penetrates the sidewall of the rectangular block 1 and cuts along the height of the rectangular block 1, including the connecting hole 10, the circular groove 11, and the spherical groove 12. The through hole 15 and the injection hole 14 are located in the upper half of the rectangular block 1. The upper wall of the lower half of the rectangular block 1 has multiple baffles 16 located between adjacent spherical grooves 12. The lower wall of the upper half of the rectangular block 1 has multiple slots 13, with the baffles 16 passing through them. An upper extension ring 17 is provided in the upper half of the rectangular block 1, concentric with the through hole 15. The upper end of the through hole 15 has a tapered structure, with the lower end being the smaller end. An inner rod 20 passes through the through hole 15, with an end cap 2 at its upper end. The lower end of the end cap 2 is threaded onto the upper extension ring 17. Multiple screws 3 are threaded through the rectangular block 1. The two ends of the screws 3 are connected to the first nut 30 by threads. The inner end of the first nut 30 acts on the upper and lower walls of the rectangular block 1.
[0025] The wires pass through the connecting hole 10, and the connection point of the two wires is located at the spherical groove 12, which is filled with conductive filler. The circular groove 11 is filled with adhesive, which is bonded to the outer layer of the wires. Connecting plates 4 are respectively fitted at both ends of the screw 3, and second nuts 31 are respectively threaded to both ends of the screw 3. The second nuts 31 act on the connecting plates 4. A clamping plate 40 is provided at the other end of the connecting plate 4, and a constraint groove 41 is opened on the inner wall of the clamping plate 40. A soft buffer layer is provided on the inner wall of the constraint groove 41.
[0026] In this specific application, the operator first connects the cables. During the connection, the operator twists the exposed sections of the cables together.
[0027] Then, the cable is placed in the lower half of the spherical groove 12 of the rectangular block 1. This process is repeated until all the cables are in place. The rectangular block 1 is then fixed by the screw 3 and the first nut 30. In order to improve the insulation effect, the cable segment passing through the circular groove 11 has a complete insulation layer on its outside.
[0028] Then, insulating glue is injected into the circular groove 11 through the connecting hole 10 so that the insulating glue fills the circular groove 11 and the connecting hole 10.
[0029] Then, the clamp 40 is used to fix the cable by tightening the second nut 31.
[0030] Next, the operator injects molten tin into the spherical groove 12 through the injection hole 14 to fill the spherical groove 12 and waits for the tin to cool. During the cooling process, the outflowing tin is scraped off to avoid affecting the insulation effect of the rectangular block 1.
[0031] Finally, the end cap 2 is threaded onto the upper extension ring 17.
[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
