Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable connector technology, and in particular to an anti-rotation structure for a cable connector. Background Technology
[0002] Cable connectors are electromechanical components used to connect wires, cables, and signal transmission between internal connections and patch panels in optoelectronic transmission equipment. Cable connectors are mainly used in various digital program-controlled exchanges, optoelectronic transmission equipment, etc., for transmitting data, audio, video and other communication signals. They ensure the speed and stability of signal transmission, and the flame-retardant materials used in the connector sheath also improve its safety factor. In addition, cable connectors are convenient to use and greatly reduce the loss rate of information transmission.
[0003] An existing anti-rotation structure for cable connectors (publication number: CN214899156U) has at least the following drawbacks:
[0004] In the aforementioned patent, the cable is fixed by pushing the push plate to drive the locking block, and the locking block pushes the bottom of the clamping block to extend below the through hole. This can effectively prevent the cable from rotating or shifting. However, the push plate and the clamping block are small in size, so the fixing effect is relatively limited. Furthermore, when the push plate and the clamping block are subjected to large forces, they may rebound, leading to fixing failure. Therefore, it is necessary to propose an anti-rotation structure for cable connectors to solve this problem. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-rotation structure for cable connectors.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An anti-rotation structure for a cable connector includes a connector head with a cable at one end and a threaded outer wall surface. It also includes an anti-rotation component disposed on the outer wall surface of the connector head to prevent the cable from rotating. The anti-rotation component includes a tail tube threaded to the outer wall surface of the connector head. The tail tube has a threaded outer wall surface and a locking nut is threaded onto it. Two second fixing holes are formed on the outer wall surface of the tail tube. A movable plate is movably fitted inside each of the second fixing holes. A first limiting plate is fixedly installed on one side of the movable plate. A spring is fixedly installed on one side of the first limiting plate. A limiting hole is formed inside one side of each of the second fixing holes, movably fitted with the first limiting plate. The spring is fixedly installed inside the limiting hole. The second limiting plate is fixedly installed on one side of the movable plate.
[0008] As a further embodiment of this utility model, the outer circular wall of the tail tube is provided with a plurality of first fixing holes, and the inner circular wall of the tail tube is movably fitted with a sealing sleeve, the sealing sleeve being movably fitted with the cable.
[0009] As a further embodiment of this utility model, a number of protruding strips are fixedly installed on the inner circular wall surface of the second limiting plate.
[0010] As a further embodiment of this utility model, the outer circular wall of the connector is threaded with a mating nut, the outer circular wall of the connector is movably fitted with a first sealing ring, and one end of the mating nut is provided with a second sealing ring, which is movably fitted with the connector.
[0011] As a further embodiment of this utility model, the inner circular wall of the threaded groove of the connector is threaded with a screw, and a guide groove is provided on one side of the movable plate.
[0012] As a further embodiment of this utility model, a third limiting plate is fixedly installed on the top and bottom surfaces of the movable plate, and a limiting groove is opened on the top and bottom surfaces of the second fixing hole, and the limiting groove is movably sleeved with the third limiting plate.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. By using the connector, cable, tail tube, first fixing hole, sealing sleeve, locking nut, and moving plate in combination, the cable can be prevented from rotating. Then, the second limiting plate, locking nut, and first fixing hole work together to fix the connecting cable initially and then twice. The double fixation can effectively prevent the connecting cable from rotating. Furthermore, the moving plate is pressed down by the tail tube and will not rebound, avoiding fixation failure and ensuring the fixation effect. It is quite practical.
[0015] 2. Through the setting of the sealing sleeve, the second sealing ring and the first sealing ring, the sealing sleeve seals the space between the tail tube and the cable, the second sealing ring seals the space between the tail tube and the connecting nut, and the first sealing ring seals the space between the connecting nut and the connector, thereby effectively preventing short circuits caused by water ingress between the connector and the cable connector. It can be used outdoors, and the sealing sleeve placed between the cable and the tail tube can effectively protect the cable. Attached Figure Description

The connector also includes an anti-rotation component, which is disposed on the outer circular wall of the connector 1 to prevent the cable 2 from rotating. The anti-rotation component includes a tail tube 3, which is threaded onto the outer circular wall of the connector 1. The outer circular wall of the tail tube 3 is threaded and has a locking nut 6 threadedly connected thereto. Two second fixing holes 8 are formed on the outer circular wall of the tail tube 3. A movable plate 7 is movably fitted inside the second fixing holes 8. A first limiting plate 10 is fixedly installed on one side of the movable plate 7. A spring 11 is fixedly installed on one side of the first limiting plate 10. A limiting hole 9 is formed on one side of the second fixing holes 8, which is movably fitted with the first limiting plate 10. The spring 11 is fixedly installed on one side of the limiting hole 9. A second limiting plate 12 is fixedly installed on one side of the movable plate 7.
[0026] In use, cable 2 is passed sequentially through locking nut 6, first fixing hole 4, sealing sleeve 5, and connecting nut 14, connecting its cable end to the mounting base of connector 1. Then, connecting nut 14 is screwed onto the outside of connector 1, and tail tube 3 is connected to the external thread of connector 1. Next, locking nut 6 is tightened to connect with the external thread of tail tube 3. Rotating locking nut 6 compresses the end of tail tube 3, while the several first fixing holes 4 allow the end of tail tube 3 to bend, further compressing the sealing sleeve 5 and thus fixing cable 2. Simultaneously, locking nut 6 compresses the guide groove 17 on one side of moving plate 7. With finger pressure on moving plate 7, it is pushed into the second fixing hole 8. Through the compression of the cable 2 sheath by second limiting plate 12 and the increased friction between second limiting plate 12 and cable 2 by protrusion 13, the initial and secondary fixing of cable 2 are achieved.
[0027] In this embodiment, the outer circular wall of the tail tube 3 is provided with several first fixing holes 4, the inner circular wall of the tail tube 3 is movably fitted with a sealing sleeve 5, the sealing sleeve 5 is movably fitted with the cable 2, the inner circular wall of the second limiting plate 12 is fixedly installed with several protrusions 13, the outer circular wall of the connector 1 is threadedly connected with a mating nut 14, the outer circular wall of the connector 1 is movably fitted with a first sealing ring 15, one end of the mating nut 14 is provided with a second sealing ring 20, the second sealing ring 20 is movably fitted with the connector 1, the inner circular wall of the threaded groove of the connector 1 is threadedly connected with a screw 16, a guide groove 17 is provided on one side of the moving plate 7, the top and bottom surfaces of the moving plate 7 are respectively fixedly installed with third limiting plates 18, the inner top and bottom surfaces of the second fixing hole 8 are respectively provided with limiting grooves 19, the limiting grooves 19 are movably fitted with the third limiting plates 18.
[0028] In use, the sealing sleeve 5, the second sealing ring 20, and the first sealing ring 15 seal the connection between the tail tube 3 and the cable 2. The second sealing ring 20 seals the connection between the tail tube 3 and the docking nut 14, and the first sealing ring 15 seals the connection between the docking nut 14 and the connector 1. This effectively prevents short circuits caused by water ingress between the connector 1 and the cable 2. It can be used outdoors, and the sealing sleeve 5, placed between the cable 2 and the tail tube 3, effectively protects the cable 2.
[0029] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: With the connector 1, when it is necessary to connect the connector 1 to the cable 2, first unscrew the connector 1 from the tail tube 3, hold the tail tube 3 and unscrew the locking nut 6. Then, pass the cable 2 sequentially through the locking nut 6, the first fixing hole 4, the sealing sleeve 5, and the mating nut 14, connecting its cable end to the mounting base of the connector 1. Next, screw the mating nut 14 to the outside of the connector 1, and then connect the tail tube 3 to the external thread of the connector 1. At the same time, gently pull the cable 2 to prevent it from bending inside the tail tube 3, and ensure that the sealing sleeve 5 is placed between the outside of the cable 2 and the inside of the end of the tail tube 3. Finally, tighten the locking nut 6 to... When the locking nut 6 is rotated and connected to the external thread of the tail tube 3, it will squeeze the end of the tail tube 3. Several first fixing holes 4 allow the end of the tail tube 3 to bend, thereby squeezing the sealing sleeve 5 and fixing the cable 2. At the same time, the locking nut 6 will squeeze the guide groove 17 on one side of the moving plate 7. With the finger pressing the moving plate 7, it will enter the second fixing hole 8. The second limiting plate 12 squeezes the outer sheath of the cable 2, and the protrusion 13 increases the friction between the second limiting plate 12 and the cable 2, thus achieving the initial and secondary fixing of the cable 2. This dual fixing method can effectively prevent the cable 2 from rotating, ensuring the fixing effect. Moreover, the moving plate 7 will not rebound when pressed down by the tail tube 3, ensuring a firm fixation, which is quite practical.
