[0025] The present invention will be described in detail below through specific embodiments to enable a better understanding of the present invention. However, the following embodiments do not limit the scope of protection of the present invention.

[0026] Example 1

[0027] This embodiment discloses a convenient installation type anti-loosening cable connector.

[0028] like Figures 1 to 4 As shown, this embodiment includes a connector body 1, which includes a cable fixing component 2 and two sheath fixing components 3. The two sheath fixing components 3 are sleeved on both ends of the cable fixing component 2. The cable fixing component 2 is rotated to tighten the two cables. The cable fixing component 2 has several grooves 4 at both ends, and the sheath fixing component 3 has several protrusions 5 at one end. The grooves 4 and protrusions 5 engage with each other, and the cable fixing component 2 and the sheath fixing component 3 are fixed by the grooves 4 and the protrusions 5.

[0029] When the sheath fixing member 3 is sleeved on the cable fixing member 2, the cooperation of the groove 4 and the protrusion 5 can provide accurate positioning and stable connection, prevent relative rotation between the two, and enhance the overall stability of the joint. The sleeving structure further enhances the connection tightness between the cable fixing member 2 and the sheath fixing member 3, and also plays a certain sealing effect, preventing dust, moisture, etc. from entering the inside of the joint and affecting the connection performance of the cable.

[0030] The cable fixing member 2 and the sheath fixing member 3 are internally provided with a fixing clamp 6, which includes a fixed end 7 and a pushing end 8. The fixed end 7 is fixed to the inner wall of the cable fixing member 2 and the sheath fixing member 3. The other side of the inner wall of the cable fixing member 2 and the sheath fixing member 3 is provided with a limiting hole 9. The pushing end 8 is provided with a rotating hole 10, and a bolt 11 is screwed on the rotating hole 10. The end of the bolt 11 is sleeved with the rotating hole 10.

[0031] When it is necessary to fix the cable, the bolt 11 is rotated. Since the bolt 11 is screwed with the rotating hole 10, the rotation of the bolt 11 will make the pushing end 8 move along the direction of the limiting hole 9, so that the distance between the pushing end 8 and the fixed end 7 is reduced. The arc groove 14 tightly clamps the cable and the sheath, realizing firm fixation of the cable.

[0032] The cable fixing member 2 is provided with an inner shrink groove 12 at both ends, and the sheath fixing member 3 is provided with an extension pipe 13 at one end. The extension pipe 13 is sleeved with the inner shrink groove 12.

[0033] The sleeving structure of the extension pipe 13 and the inner shrink groove 12 plays a certain sealing effect to a certain extent, which can prevent dust, moisture, etc. from entering the inside of the joint, protect the cable and the joint from the invasion of the external environment, and prolong the service life of the cable joint.

[0034] The side adjacent to the fixed end 7 and the pushing end 8 is provided with an arc groove 14, which is used for clamping the cable and the sheath.

[0035] The shape of the arc groove 14 is matched with the cable and the sheath, which is used for clamping the cable and the sheath.

[0036] The top of the bolt 11 is provided with a knob 15.

[0037] The operator can directly operate the bolt 11 by rotating the knob 15, without using additional tools, which greatly improves the convenience of installation and disassembly.

[0038] Preparation: The end portions of the two cables to be connected are appropriately treated to remove the insulation layer and expose the conductor of appropriate length.

[0039] Cable joint: insert two ends of the cable into the cable fixing part 2, and make the conductor part of the cable in the right position. Rotate the knob 15 on the top of the bolt 11 to make the advancing end 8 move to the fixed end 7, and the arc groove 14 gradually clamps the cable until the right clamping force is reached, and then rotate the cable fixing part 2 to make the two ends of the cable relatively tighten.

[0040] Connecting fixing part: the two sheath fixing parts 3 are respectively sleeved on the two ends of the cable fixing part 2, and the recess 4 and the protrusion 5 are accurately engaged, and the extension pipe 13 is closely sleeved with the retracted groove 12.

[0041] Sheath locking: rotate the knob 15 on the top of the bolt 11 to make the advancing end 8 move to the fixed end 7, and the arc groove 14 gradually clamps the sheath until the right clamping force is reached.

[0042] The specific embodiments of the utility model are described in detail above, but it is only as an example, the utility model is not equal to the specific embodiments described above. For those skilled in the art, any equivalent modification and replacement to the utility model are also in the scope of the utility model. Therefore, any equivalent transformation and modification made without departing from the spirit and scope of the utility model should be covered in the scope of the utility model.
