Technical Field

[0001] This utility model relates to the field of cable connection component technology, and in particular to a communication cable connection component that is easy to install and disassemble. Background Technology

[0002] Communication cables are wires that transmit electrical or optical signals. They are usually composed of several or groups of wires, with at least two wires twisted together in each group, resembling ropes. They are widely used in home decoration, power, communication and related transmission applications.

[0003] In existing technologies, when connecting two communication cables, it is necessary to peel off the insulation layer, manually twist the corresponding colored cable cores together, manually wrap multiple layers of insulating tape, or put a heat shrink tube on the connection point and heat it with a heat gun or torch to shrink and tighten it. However, this connection method is not very convenient for installation and disassembly. Utility Model Content

[0041] See Figures 1-7 A communication cable connection assembly that is easy to install and disassemble includes: a cable core fixing sleeve, a first connecting sleeve, and a second connecting sleeve.

[0042] The cable core fixing sleeve includes: a sleeve 1, with a plurality of cable core connection channels 2 extending through the sleeve 1. The number of cable core connection channels 2 can be determined according to the number of cable cores in the communication cable, for example, see... Figure 2 The sleeve 1 contains two cable core connection channels 2, which can be used to connect communication cables with two cable cores. See [link / reference]. Figure 3 The sleeve 1 has four cable core connection channels 2, which can be used to connect four cable cores of communication cables. The sleeve 1 has several threaded holes in the middle of its side wall that communicate with the cable core connection channels 2. Each cable core connection channel 2 corresponds to one threaded hole. When in use, the insulation layer of the cable core is peeled off, the cable cores of the two cables are inserted into the corresponding cable core connection channels according to their functions, the crimping screws 3 are inserted into the threaded holes and tightened to fix the two cable cores and complete the electrical connection.

[0043] Both the first and second connecting sleeves include: a threaded tube 4, one end of which is connected to a fixed tube 5; threads are provided on both ends of the outer wall of the sleeve 1; the threaded tube 4 is used for threaded connection with the sleeve 1; several clamping claws 6 are connected to the end of the fixed tube 5 away from the threaded tube 4, with gaps between adjacent clamping claws 6 to provide elastic deformation capability for inward contraction; grooves are provided in the clamping claws 6 to jointly fix a lip seal ring 20; a first sealing tube 7 is connected to the end of the threaded tube 4 of the first connecting sleeve away from the clamping claws 6; a second sealing tube 8 is connected to the end of the threaded tube 4 of the second connecting sleeve away from the clamping claws 6; the diameter of the first sealing tube 7 is larger than the diameter of the fixed tube 5, so that the connection between the first sealing tube 7 and the fixed tube 5 forms a... The docking platform is equipped with a first sealing ring 9. The outer diameter of the second sealing tube 8 matches the inner diameter of the first sealing tube 7. The inner diameter of the second sealing tube 8 is slightly larger than the outer diameter of the fixing tube 5. A limit plate 10 is connected to the outer wall of the second sealing tube 8, and a second sealing ring 11 is connected to the limit plate 10. During connection, the threaded tube 4 of the first connecting sleeve is turned. After tightening, the first sealing tube 7 just covers the position of the crimping screw 3. Then, the threaded tube 4 of the second connecting sleeve is turned. During the turning process, the second sealing tube 8 enters the first sealing tube 7. After tightening, the end of the second sealing tube 8 is pressed and connected with the first sealing ring 9, and the end of the first sealing tube 7 is pressed and connected with the second sealing ring 11, thereby protecting and sealing the position of the threaded hole used to fix the cable core.

[0044] To fix the first and second connecting sleeves to the two cables respectively, sliding locking sleeves are connected to the fixing tubes. Each sliding locking sleeve includes a first receiving groove 12 formed on the outer wall of the fixing tube 5, and a sliding sleeve 13 slidably connected to the outer wall of the fixing tube 5. A second receiving groove 14 is formed on the inner wall of the sliding sleeve 13. A spring 15 is sleeved on the fixing tube 5 and located within the first and second receiving grooves 12 and 14. A limit groove 16 is formed on the outer wall of the fixing tube 5. (See [reference]) Figure 6 The limiting groove 16 is located above the first receiving groove 12. The inner wall of the end of the sliding sleeve 13 away from the clamping claw 6 is connected to the limiting block 17. The limiting block 17 is slidably connected in the limiting groove 16. An L-shaped sliding groove 18 is provided in the limiting groove 16. A slider 19 is connected on the limiting block 17. The slider 19 is slidably connected in the L-shaped sliding groove 18.

[0045] When a cable needs to be passed through, slide the sliding sleeve 13 upwards, compress the spring 15, and slide the slider 19 upwards along the vertical groove of the L-shaped groove 18. When it reaches the top, rotate the sliding sleeve 13, and the slider 19 enters the horizontal groove of the L-shaped groove 18 to fix the sliding sleeve 13. At this time, several clamping claws 6 open outwards in a trumpet shape. Pass the cable through the fixing tube 5 and the threaded tube 4 first, fix the cable core in the cable core fixing sleeve, and connect the threaded tube 4 to the cable core fixing sleeve. Then rotate the sliding sleeve 13, and the slider 19 enters the vertical groove of the L-shaped groove 18. Slide the sliding sleeve 13 towards the clamping claws 6. The inner wall of the end of the sliding sleeve 13 facing the clamping claws 6 has a sloping structure. By squeezing the clamping claws 6 through the sloping surface, the clamping claws 6 simultaneously retract towards the center and squeeze the lip seal ring to achieve a radial dynamic seal between the cable sheath and the clamping claws. At this time, the spring 15 is in the normal state and provides preload.

[0046] When disassembly is required, slide the sliding sleeve 13 upwards, compress the spring 15, open the clamping claw 6, and turn the threaded tube 4 to remove the entire first connecting sleeve and the second connecting sleeve from the cable core fixing sleeve. Then, remove the fixing crimping screw and pull out the cable core.

[0047] It is worth noting that, firstly, this utility model designs a cable core fixing sleeve with several cable core connection channels that run through it. The fixed channel design, which prevents mis-insertion, ensures correct wiring. The connection is firm and reliable through crimping screws, and the operation is simple and quick. In addition, a first connecting sleeve and a second connecting sleeve are provided. The first connecting sleeve and the second connecting sleeve are detachably connected to the cable core fixing sleeve through the threaded tubes on the first connecting sleeve and the second connecting sleeve. The fixing sleeve, clamping claws, and sliding locking sleeve are used to fix it to the cable, thus protecting and sealing the cable core fixing sleeve and preventing pulling.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
