[0026] Please see Figures 1-4 This embodiment discloses a connection structure for twisted-pair cables, including a male cable connector 1 and a female cable connector 2 that are plugged into each other. In this embodiment, a first locking member and a second locking member that can lock each other are respectively provided on the male cable connector 1 and the female cable connector 2, so that the first locking member and the second locking member lock each other after the male cable connector 1 and the female cable connector 2 are connected. Compared with the connection method of using tape wrapping in the prior art, the locked male cable connector 1 and the female cable connector 2 improve the connection strength.

[0027] Preferably, the first locking member includes a cylindrical member sleeved on the male cable connector 1, wherein the cylindrical member is movable along the axial direction of the male cable connector 1, one end of the cylindrical member is connected to the male cable connector 1 by an elastic member, and the other end is provided with a locking block 9; for example Figure 3 As shown, this embodiment provides one arrangement of the locking blocks 9. The locking blocks 9 are protrusions, there are two of them, and they are arranged opposite each other on both sides of the cylindrical component. In addition, there may be one or more locking blocks 9.

[0028] Preferably, the second locking member includes a limiting sleeve 10 disposed on the female cable end 2, the outer wall of the limiting sleeve 10 having a limiting groove 11 into which the locking block 9 can slide, and the inner end of the limiting groove 11 being bent to one side to form a locking groove.

[0029] The outer diameter of the cylindrical component is smaller than the inner diameter of the limiting sleeve 10, so that the cylindrical component can be inserted into the limiting sleeve 10. The cylindrical component is screwed so that it can rotate radially within the limiting sleeve 10. At this time, the locking block 9 slides into the locking groove along the limiting groove 11, so that the cylindrical component and the limiting sleeve 10 are fitted on the outside of the male cable head 1 and the female cable head 2 and locked and fixed.

[0030] It should be noted that the limiting groove 11 is opened along the axial direction of the limiting sleeve 10, with one end open and the other end bent to one side to form a slot. The slot and the limiting groove 11 form an "L" shape.

[0031] In this embodiment, as Figure 3 As shown, the cylindrical component includes a connecting sleeve 6 and a locking sleeve 8 that are inserted into each other. The locking sleeve 8 is inserted into the connecting sleeve 6, and a positioning groove 7 for engaging an elastic element is formed between the locking sleeve 8 and the connecting sleeve 6. Specifically, the locking sleeve 8 is a hollow cylinder, with one end of the connecting sleeve 6 open and the other end forming an annular cylinder. The hollow cylinder is inserted into the annular cylinder, with a gap between the end of the hollow cylinder and the annular portion of the annular cylinder, and the two are connected by a threaded assembly. The positioning groove 7 is an annular groove provided at the gap.

[0032] In this embodiment, as Figure 4 As shown, the elastic element includes a fixing sleeve 3 fixed to the outside of the male cable connector 1. A sliding ring 5 is connected to the rear side of the fixing sleeve 3 via a spring 4, and the sliding ring 5 is embedded in the positioning groove 7. It should be noted that the sliding ring 5 can rotate freely within the positioning groove 7.

[0033] The first and second locking components are provided with an outer protective sleeve 18 that covers the connection end of the male cable head 1 and the female cable head 2. The sleeve covers the outside of the first and second locking components to form an outer protection, preventing the intrusion of moisture and dust, and effectively preventing damage to the connection point of the male cable head 1 and the female cable head 2.

[0034] In this embodiment, the outer protective sleeve 18 includes a retractable outer sleeve 13, specifically a telescopic sleeve. One end of the outer sleeve 13 is connected to the female cable connector 2 via a first connector 12, and the other end is connected to the male cable connector 1 via a detachable connection structure. The first connector 12 is a closed cover, which closes one end of the outer sleeve 13 to the female cable connector 2. Since the other end is a detachable connection structure, the outer sleeve 13 can be disengaged from the male cable connector 1 when inserting or removing the male cable connector 1 and the female cable connector 2, or when the first locking member and the second locking member are unlocked.

[0035] Specifically, the detachable connection structure includes a movable flange assembly disposed on the outer sleeve 13 and an assembly flange 17 disposed on the male cable connector 1, with the movable flange assembly being assembled on the assembly flange 17.

[0036] The movable flange assembly includes a second connector 14 fixed to the end of the outer sleeve 13. Several lugs 16 are evenly distributed around the second connector 14, and the lugs 16 are fixed to the assembly flange 17 by bolts. The second connector 14 is a ring.

[0037] A sealing ring 15 is provided on the outer wall surface of the second connector 14. The sealing ring 15 increases the sealing performance of the second connector 14 after it is assembled with the assembly flange 17.

[0038] In use, insert the male cable connector 1 into the female cable connector 2, push the connecting sleeve 6 to drive the locking sleeve 8 and the locking block 9 into the limiting groove 11, and then rotate to make the locking block 9 lock into the slot on one side of the limiting groove 11. At this time, the sliding ring 5, under the action of the spring force of the spring 4, pushes the connecting sleeve 6, the locking sleeve 8 and the locking block 9 backward, so that the locking block 9 is locked in the slot. The locking sleeve 8, the locking block 9 and the limiting sleeve 10 are used to position and reinforce the male cable connector 1 and the female cable connector 2, preventing the female cable connector 2 from detaching from the surface of the male cable connector 1.

[0039] After the connection is completed, the outer sleeve 13 is sealed outside the first and second locking parts by the assembly of the lug 16 and the assembly flange 17, forming an outer protection to prevent the intrusion of water vapor and dust, and effectively prevent damage to the connection between the male cable head 1 and the female cable head 2.

[0040] In summary, this connection structure for twisted-pair cables, through the second connector 14, sealing ring 15, lug 16, mounting flange 17, and outer protective sleeve 18, solves the problem that during the use of this device, the connection position is usually sealed by heat shrinking the protective sleeve, and after sealing, it usually requires professional scissors to cut open. In subsequent maintenance of the connection position, the cable is easily damaged due to cutting, which is inconvenient for people to use.
