[0026] The present invention will be described in detail below with reference to the accompanying drawings and embodiments, but the present invention is not limited to these embodiments.

[0027] like Figure 1 and Figure 2 As shown, the utility model provides a cable connector, including a shell and a crimping ring 4, the shell having an annular mounting portion 1 and a conical crimping portion 2, the annular mounting portion 1 and the conical crimping portion 2 are coaxially arranged, and the diameter of the conical crimping portion 2 gradually decreases as it moves away from the annular mounting portion 1; the shell is provided with at least two groups of wire threading grooves 3 along the center line direction, and the adjacent sides of the two groups of wire threading grooves 3 are connected; a connecting portion 5 is provided on one side of the inner circumference of the crimping ring 4, and a conical extrusion portion 6 extends inwardly on the other side of the inner circumference of the crimping ring 4; the connecting portion 5 passes through the conical crimping portion 2 and is installed on the annular mounting portion 1, so that the conical extrusion portion 6 is crimped on the outer circumference of the conical crimping portion 2 to clamp the cables passed through the two groups of wire threading grooves 3, so that the two groups of cables are closely fitted to form line contact, thereby extending the effective contact length of the cables, so that when any cable is subjected to tension, its contact surface is not easily disconnected, thereby ensuring that the use effect is not affected.

[0028] Furthermore, the number of wire threading grooves 3 is set to 3-5, which is convenient for synchronous connection of multiple cables; one of the wire threading grooves 3 is located on the central axis of the shell, and the remaining wire threading grooves 3 are evenly distributed circumferentially around the central axis of the shell, and the wire threading grooves 3 on the central axis of the shell are respectively connected to the adjacent sides of the remaining wire threading grooves 3; specifically, the main cable can be inserted into the wire threading groove 3 on the central axis of the shell, and the auxiliary cable can be inserted into the wire threading groove 3 on the circumference of the main cable, and then the connecting part 5 is fixed on the annular mounting part 1, so that the conical extrusion part 6 presses the conical crimping part 2 on the outer periphery of multiple auxiliary cables, thereby completing the synchronous installation of multiple cables and ensuring uniform force between the multiple auxiliary cables and the main cable.

[0029] In one of the above embodiments, the tapered crimping portion 2 is a rubber sleeve, which is easy to deform after being subjected to the squeezing force, thereby clamping and fixing the cable.

[0030] In another embodiment described above, the outer periphery of the conical crimping portion 2 has a slot corresponding to the position of the wire threading groove 3, and a pressure plate 7 is provided in the slot. The pressure plate 7 extends to the outside of the slot away from the wire threading groove 3 and is adapted to the conical extrusion portion 6. One end of the pressure plate 7 is integrally formed and mounted on the annular mounting portion 1, and the other end of the pressure plate 7 is movably mounted in the slot. When the connecting portion 5 drives the conical extrusion portion 6 to move toward the side close to the annular mounting portion 1, the conical extrusion portion 6 presses the movable end of the pressure plate 7 into the slot to clamp and fix the cable in the wire threading groove 3. Furthermore, the side of the pressure plate 7 close to the wire threading groove 3 is an arc-shaped surface, which can increase the effective contact area between the pressure plate 7 and the cable, guide the cable during the clamping process, and prevent the pressure plate 7 from pinching off the cable core.

[0031] In the above, insulating sleeves 10 are provided at both ends of the housing. One end of the wire duct 3 passes through either insulating sleeve 10, and a wire hole 8 is formed in the insulating sleeve 10. When the cable core is inserted into the wire duct 3, the insulation layer of the cable extends into the wire hole 8, thereby improving the insulation effect. Furthermore, a plugging cap 9 is installed in the wire hole 8 to facilitate blocking the unused wire hole 8.

[0032] In this embodiment, the connecting portion 5 is threadedly mounted on the outer circumference of the annular mounting portion 1, which not only enables the clamping and securing of cables of different sizes, but also allows the clamping force to be adjusted by rotational force during the clamping process. In other embodiments, the connecting portion 5 can also be snap-fitted onto the outer circumference of the annular mounting portion 1 to facilitate quick cable clamping.

[0033] The above descriptions are merely several embodiments of the present invention and do not constitute any form of limitation to the present invention. Although the present invention is disclosed as a preferred embodiment as above, they are not intended to limit the present invention. Any technician familiar with the profession, without departing from the scope of the technical solution of the present invention, who makes slight changes or modifications using the technical contents disclosed above, is equivalent to an equivalent implementation case and falls within the scope of the technical solution.
