[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] According to an embodiment of the present invention, a bend-resistant cable connector is provided.

[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-4 As shown, the anti-bending cable connector according to an embodiment of the present invention includes a connector body 1, a threaded portion 2 integrally formed on the connector body 1, and an anti-bending portion 3 provided above the threaded portion 2. The upper end of the threaded portion 2 is provided with a plurality of notches 13. The top end of the anti-bending portion 3 is integrally provided with a fastening cap 5, and the bottom end of the anti-bending portion 3 is fixed with a nut 4 threadedly connected to the threaded portion 2. A flared inner wall 11 is provided at the connection between the anti-bending portion 3 and the nut 4. One end of the threaded portion 2 with notches 13 abuts against the flared inner wall 11. Supports 6 are fixed on the left and right sides of the fastening cap 5, and a threaded post 7 is threadedly connected to the surface of the support 6. A limiting block 8 is bonded to one end of the threaded post 7, and a connecting shell 10 is provided around the limiting block 8 and sleeved with the end of the threaded post 7. An arc-shaped clamp 9 is fixed on the connecting shell 10. The cable connector of this device is composed of the threaded portion 2 and the anti-bending portion 3 threadedly connected above it. The anti-bending portion 3 is similar to a spring structure.

[0023] In one embodiment, the portion of the threaded part 2 that abuts against the flared inner wall 11 has a tapered structure, and several notches 13 are arranged around the center of the threaded part 2. With this structure, it is easy to tighten the port diameter of the threaded part 2 through the gaps of the notches 13, meet the cable clamping requirements, and is suitable for the installation of cables of different sizes.

[0024] In one embodiment, the connecting shell 10 is composed of an annular portion and an L-shaped support leg, and the L-shaped support leg of the connecting shell 10 is connected to the arc clamping piece 9, and the annular portion of the connecting shell 10 is sleeved with the threaded post 7. With this structure, the connecting shell 10 serves as a connector between the threaded post 7 and the arc clamping piece 9, so that the arc clamping piece 9 does not rotate with the rotation of the threaded post 7.

[0025] In one embodiment, a water-blocking sealing ring 12 is embedded inside the connector body 1, and two hexagonal nuts are provided on the connector body 1 from bottom to top. This structure facilitates the water blocking and installation of the connector body 1.

[0026] In one embodiment, the anti-bending part 3 is in a whole tower-shaped spiral structure, and the side surface of the fastening cap 5 is provided with a clearance opening corresponding to the arc-shaped clamping piece 9. With this structure, the joint body 1 can be bent arbitrarily, meets the inclination of the cable at any angle, and has the advantage of anti-bending through the elastic support of the tower-shaped spiral structure.

[0027] In one embodiment, the support 6 is provided with a screw hole corresponding to the threaded column 7, and the threaded column 7 is provided with a butterfly hand rotating part away from the support 6. With this structure, the threaded column 7 is easily screwed with the support 6, and the threaded column 7 is easily rotated.

[0028] Working principle:

[0029] In use, first, the cable is inserted into the joint body 1 and the anti-bending part 3 installed above the joint body 1. When the cable is clamped, the threaded column 7 screwed on the support 6 is rotated to push the arc-shaped clamping piece 9 into the inside of the fastening cap 5, so that the arc-shaped clamping piece 9 is clamped and connected with the cable inserted into the anti-bending part 3. On this basis, the nut 4 at the bottom of the anti-bending part 3 is rotated to gradually compress the upper end of the threaded part 2 in the process of deepening into the nut 4. Since the upper end of the threaded part 2 is provided with a plurality of openings 13 around, the upper end of the threaded part 2 is compressed by the horn-shaped inner wall 11 to tighten its caliber, so as to realize the tightening of the cable in the joint body 1, easily clamp and lock the cable of different sizes, and have high adaptability and reliable installation.
