Technical Field

[0001] This utility model belongs to the field of high current connector technology, and specifically refers to a cable bending structure. Background Technology

[0002] High-current connectors are fundamental to industrial power transmission and play a crucial role. Proper selection and scientific design of high-current connectors can ensure the efficient, safe, and stable operation of power systems. A high-current connector typically consists of head and tail connectors at both ends and a cable in the middle, which usually contains one or more core wires to meet the requirements of high-current transmission.

[0003] Typically, the two ends of a high-current connector are not connected in a straight line; misalignment or angular displacement may occur at the head and tail joints. Therefore, the cable needs to be bent to meet the required mating angle. However, when the core wire inside the cable is thick (1.5cm), it is not easy to bend manually, and the bends in the cable need to be pre-shaped. Utility Model Content

[0010] Preferably, the inner walls of both the first and second internal fixation members are provided with a plurality of interlaced ribs forming a grid structure.

[0011] The second specific plan is: The internal fixing component includes collars respectively fitted at both ends of the bend, and a connecting piece connecting the two collars; the collars and the connecting piece are integrally formed on the surface of the cable by injection molding, and the connecting piece is attached to the outer side of the bend.

Detailed Implementation

[0023] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0024] This utility model discloses a cable bending structure, including a cable 1 bent at a preset angle, an inner fixing member 2 fixed at the bending point 11 of the cable 1, and an outer fixing member 3 covering the surface of the inner fixing member 2.

[0025] Through the above solution, this utility model fixes the shape of the bend 11 by installing an inner fixing member 2 at the bend 11 of the cable 1, thereby maintaining the relative angle of the bend 11; at the same time, the inner fixing member 2 is also covered by an outer fixing member 3, which can not only reinforce the inner fixing member 2 to prevent it from moving or demolding, but also cover the inner fixing member 2.

[0026] In some embodiments of this utility model, the external fixing member 3 is injection molded using the same material as the surface layer of the cable 1, which enables the high-current connector to maintain a consistent appearance by using the same material as the surface layer of the cable 1.

[0027] Furthermore, the surface of the aforementioned inner fastener 2 is provided with several grooves 20. Thus, during the injection molding process of the outer fastener 3, the material of the outer fastener 3 flows into the grooves 20 and, after curing, forms a columnar structure that inserts into the inner fastener 2, thereby improving the bonding strength between the outer fastener 3 and the inner fastener 2.

[0028] In some embodiments of this utility model, connectors are provided at both ends of the cable 1, namely the head and tail connectors of a high current connector.

[0029] Specifically, refer to Figure 1-4 The first embodiment of the present invention is shown in the figure.

[0030] In the first embodiment, the aforementioned internal fixation member 2 includes a first internal fixation member 21 and a second internal fixation member 22 with a separate design. Both the first internal fixation member 21 and the second internal fixation member 22 are made of metal material and have sufficient strength and hardness to tighten and fix the bend 11 of the cable 1, and can effectively maintain the shape of the bend 11, that is, maintain the relative angle of the bend 11.

[0031] Furthermore, a plurality of mating posts 211 and mating holes 221 are respectively provided at the edge joint of the first internal fixation member 21 and the second internal fixation member 22. The mating posts 211 are inserted into the corresponding mating holes 221 to realize the assembly of the first internal fixation member 21 and the second internal fixation member 22.

[0032] Secondly, the first internal fixation component 21 and the second internal fixation component 22 are connected by welding after assembly to form an integral structure.

[0033] Furthermore, the inner walls of the first internal fixation member 21 and the second internal fixation member 22 are provided with a number of interlaced ribs 212 and 222 forming a grid structure.

[0034] refer to Figure 5 As shown, a second embodiment of the present invention is illustrated.

[0035] In the second embodiment, the aforementioned inner fixing member 2 includes collars 23 respectively fitted onto both ends of the bend 11, and a connecting piece 24 connecting the two collars 23. The collars 23 and the connecting piece 24 are integrally formed on the surface of the cable 1 by injection molding, and the connecting piece 24 is attached to the outer side 111 of the bend 11. Thus, the connecting piece 24 serves as a reinforcement on the outside of the bend 11, connecting the collars 23 at both ends into one piece, which can help maintain the shape of the bend 11. At the same time, during the injection molding of the outer fixing member 3, the material of the outer fixing member 3 is injected into the position of the bend 11 located between the two collars 23, forming a step around the connecting piece 24. After curing, a protrusion structure is formed between the two ends of the inner fixing member 2, improving the bonding between the outer fixing member 3 and the inner fixing member 2.

[0036] Furthermore, each of the aforementioned collars 23 has at least one groove 20 on its circumferential surface.

[0037] refer to Figure 6 As shown, a second embodiment of the present invention is illustrated.

[0038] In the third embodiment, the aforementioned internal fixation member 2 is coated on the circumferential surface of the turning point 11 by injection molding, and a groove 25 is provided at the inner side 112 of the turning point 11. Thus, by designing the groove 25 at the inner side of the turning point 11, the thickness of the internal fixation member 2 at this location is reduced, decreasing the material's resistance and thus maintaining its shape. Simultaneously, during the injection molding of the external fixation member 3, the material of the external fixation member 3 is poured into the groove 25, and after curing, forms a protrusion structure inserted between the two ends of the internal fixation member 2, improving the bonding strength between the external fixation member 3 and the internal fixation member 2.

[0039] Furthermore, at least one countersunk hole 26 is provided within the aforementioned settling tank 25, which can further reduce the resistance of the material. Preferably, the countersunk hole 26 is located in the middle of the settling tank 25.

[0040] Meanwhile, at least one groove 20 is provided on both ends of the aforementioned internal fixing member 2.

[0041] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
