[0022] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in conjunction with the embodiments below. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model. As used in this article, the terms up and down and left and right are not limited to their strict geometric definitions, but include reasonable and inconsistent tolerances for machining or human errors. The specific features of this multi-strand cable connector are described in detail below:

[0023] Reference Figure 1-Figure 8According to an embodiment of the utility model, a multi-strand cable connector includes a connector body 10, and connecting tubes 12 are fixed at both ends of the left and right ends of the connector body 10. A circumferentially distributed locking plate 21 is fixed on one end of the outer side of each connecting tube 12, and a locking block 22 is fixed on the inner side of each locking plate 21. A pipe sleeve 13 is threadedly fitted on the outer periphery of each connecting tube 12, and a locking ring 20 is fixed in each pipe sleeve 13. Two upper and lower symmetrical clamping boxes 15 are arranged in the connector body 10, and a clamping seat 16 is fixed in each clamping box 15. Four connecting rods 19 are fixed on the upper end surface of the lower clamping box 15, and a limiting rod 29 is arranged on the upper end of each connecting rod 19, and each limiting rod 29 can abut against the upper clamping box 15.

[0024] A cavity 14 that passes through the joint body 10 from left to right is provided in the joint body 10, and a clamping box 15 on the lower side is fixed on the lower side wall of the cavity 14. A box cover 11 is provided in the upper end surface of the joint body 10, and the front end surface of the box cover 11 is hinged to the front end surface of the joint body 10. A connecting plate 18 is fixed on the lower side wall of the cavity 14, and the rear end surface of the connecting plate 18 is fixed on the rear side wall of the cavity 14. Two left-right symmetrical limiting protrusions 24 are provided on the upper end of the connecting plate 18. Two left-right symmetrical limiting cavities 23 are provided in the front end surface of the joint body 10, and the two limiting protrusions 24 can be respectively inserted into the limiting cavities 23 on the corresponding sides, thereby realizing the fixation between the box cover 11 and the joint body 10.

[0025] The clamping seats 16 on the upper and lower sides are provided with equidistantly distributed isolation grooves 17, and the left and right ends of the isolation grooves 17 are opened. The clamping seats 16 on the upper and lower sides can abut against each other. Through the mutual abutment between the two clamping seats 16, the isolation grooves 17 on the upper and lower sides can clamp the connection positions of multiple cables.

[0026] Four limiting grooves 25 are provided in the upper end surface of the upper clamping box 15, and the four connecting rods 19 can pass through the upper clamping box 15. A through cavity 30 that passes through left and right is provided in the upper end of each connecting rod 19, and each through cavity 30 is collinear with the limiting groove 25 on the corresponding side. The four limiting rods 29 are respectively located in the four through cavities 30, and each limiting rod 29 is provided with a through groove 28 that passes through front and back. A connecting shaft 27 is fixed between the front and rear side walls of each through cavity 30, and each connecting shaft 27 passes through the through groove 28 on the corresponding side, and each through groove 28 can respectively abut against the lower side wall of the limiting groove 25 on the corresponding side, so that the through groove 28 can limit the movement of the upper clamping box 15, thereby fixing the clamping boxes 15 on the upper and lower sides.

[0027] A storage cavity 26 is provided in each connecting rod 19, and the upper end of each storage cavity 26 is connected to the through cavity 30 on the corresponding side. The left and right ends of each limit rod 29 are arc-shaped. The storage cavity 26 is used to store the limit rod 29 and make it vertical so that the upper clamping box 15 can be detached from the connecting rod 19.

[0028] The two connecting tubes 12 are connected to the cavity 14, and the outer side surface of each locking plate 21 gradually shrinks toward the axial direction of the connecting tube 12 in the direction away from the cavity 14. The inner side surface of the locking ring 20 is parallel to the outer side surface of the locking plate 21. The locking ring 20 can abut against the outer periphery of the locking plate 21. By rotating the pipe sleeve 13, the locking ring 20 can be moved closer to the locking plate 21, thereby causing the locking plate 21 to shrink inward.

[0029] When used specifically:

[0030] The multiple cables are inserted through the connecting tubes 12 on the left and right sides respectively, and the cable connection positions are placed in the cavity 14 .

[0031] After the multiple cables are connected respectively, after the line connection is covered with insulating tape, the multiple cables are placed in the multiple isolation grooves 17 on the lower side.

[0032] Then, the upper clamping box 15 is covered on the lower clamping box 15, and the four connecting rods 19 are all passed through the upper clamping box 15. Then, the four limiting rods 29 are respectively pulled out from the storage chambers 26 on the corresponding sides, and then rotated to make them horizontal, so that the four limiting rods 29 are respectively abutted against the limiting grooves 25 on the corresponding sides.

[0033] At this time, due to the limiting effect of the limiting rod 29, the clamping boxes 15 on the upper and lower sides are fixed, so that the isolation grooves 17 on the upper and lower sides clamp the multiple cables, thereby isolating the multiple cables from each other, protecting the cables while preventing them from leakage and short circuit.

[0034] Then the two sleeves 13 are rotated to move inwards, thereby driving the locking ring 20 to move toward the locking plate 21 on the corresponding side, so that the locking plate 21 contracts inwards, and the locking block 22 contracts inwards to clamp the cable.

[0035] Finally, the box cover 11 is closed, and the limiting protrusion 24 is inserted into the limiting cavity 23 .

[0036] It is clear to those skilled in the art that various modifications to the above embodiments can be made without departing from the overall spirit and concept of the present invention. All of them fall within the protection scope of the present invention. The protection scheme of the present invention shall be subject to the claims attached to the present invention.
