[0031] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0032] This embodiment relates to a cable butt joint, the overall structure of which is as follows: Figure 1 and Figure 2 As shown, it includes a housing 1, a base 4, a clamping assembly 5, and a fastener 6.

[0033] There are two shells 1 which are interlocked; openings 2 for cables to pass through are provided on both sides of the shell 1, a sealing gasket 3 is provided in the opening 2, a base 4 is fixedly arranged inside the shell 1, a clamping assembly 5 is slidably arranged inside the base 4, the clamping assembly 5 fixes the cable in the base 4, and a fastener 6 is passed through the two shells 1 and the base 4.

[0034] It is worth mentioning that the two shells 1 cover the base 4 and are inserted from the upper and lower ends of the base 4 respectively. Such a configuration can better protect the joints. The openings 2 are respectively opened on both sides of the shell 1 for a connected state. The cable is inserted into the base 4 from the opening 2. The sealing gasket 3 is in contact with the cable, which can improve the sealing of the shell 1 and prevent water vapor from entering. The clamping assembly 5 can fix the cable on the base 4 to prevent the cable from loosening. The fastener 6 can fix the shell 1 on the base 4 and ensure that the clamping assembly 5 remains in a tight state.

[0035] Based on the above overall introduction, an exemplary structure of the cable butt joint connector of this embodiment is as follows: Figure 2 As shown, a strip hole 7 is formed through the side of the base 4, a connecting groove 8 connected to the strip hole 7 is formed on the top of the base 4, and the clamping assembly 5 is located in the middle of the strip hole 7. Specifically, the opening direction of the strip hole 7 is the same as the opening direction of the opening 2, and is formed horizontally on the base 4. The cables are located at both ends of the strip hole 7, and the connecting groove 8 is located at the top of the base 4 and in the middle of the strip hole 7. The connecting groove 8 can facilitate the action of the clamping assembly 5, ensuring that the clamping assembly 5 can fix two cables at the same time when performing the clamping action, ensuring convenient installation.

[0036] As a preferred embodiment, Figure 5 As shown, in this embodiment, the clamping assembly 5 includes a top block 501 slidably arranged in the strip hole 7, a lifting block 502 driving the top block 501 to slide, and a connecting rod 503 rotatably connected between the top block 501 and the lifting block 502, and the lifting block 502 is lifted and lowered in the connecting groove 8. It should be noted that the top block 501 slides laterally along the strip hole 7, and the two top blocks 501 clamp the cable at both ends of the strip hole 7 respectively, and the lifting and lowering of the lifting block 502 can control the lateral sliding of the top block 501, and the connecting rod 503 is used to connect the lifting block 502 and the top block 501, and the two ends of the connecting rod 503 are respectively connected to the rotating shafts of the lifting block 502 and the top block 501, so that the vertical movement of the lifting block 502 can drive the top block 501 to complete the lateral movement, and the lifting block 502 can be lifted and lowered to be flush with the top of the connecting groove 8.

[0037] As a preferred embodiment, Figure 3As shown, in this embodiment, the fastener 6 includes a first bolt 601 and a second bolt 602. A first threaded hole 603 is formed at the tail of the first bolt 601. The first bolt 601 and the second bolt 602 pass through the two housings 1 respectively, and the second bolt 602 is screwed to the first threaded hole 603. A second threaded hole 604 is formed in the middle of the lifting block 502, and the first bolt 601 is screwed to the second threaded hole 604.

[0038] It should be noted that the first bolt 601 is penetrated on the upper end shell 1, and the second bolt 602 is penetrated on the lower end shell 1. After the second bolt 602 is inserted into the shell 1, it is screwed with the second bolt 602 hole. The second bolt 602 rises and falls in the first threaded hole 603. Such a setting can ensure that the first bolt 601 and the second bolt 602 can fix the shell 1 on the base 4, and the first bolt 601 and the second threaded hole 604 on the lifting block 502 are screwed. When the first bolt 601 rotates, it can drive the lifting block 502 to rise and fall. The lifting block 502 drives the top block 501 to slide through the connecting rod 503, ensuring that the top block 501 fixes the cable in the strip hole 7, and then rotates the second bolt 602, so as to fix the first bolt 601 on the shell 1. Since the first bolt 601 and the second bolt 602 are mutually fastened to the shell 1, it is ensured that the top block 501 always clamps the cable.

[0039] As a preferred example, Figure 4 As shown, the bottom of the base 4 of this embodiment is provided with a through hole 605 connected with the strip hole 7, and the first bolt 601 passes through the through hole 605. An auxiliary block 9 is fixedly provided at the bottom of the strip hole 7, and a trapezoidal groove 10 is provided on the auxiliary block 9. A trapezoidal block 11 is fixedly provided at the bottom of the lifting block 502, and the trapezoidal block 11 is inserted into the trapezoidal groove 10. Specifically, the through hole 605 is provided in the middle of the base 4 and the middle of the auxiliary block 9. The first bolt 601 can pass through the through hole 605 and be screwed with the second bolt 602. The auxiliary block 9 is located at the lower part of the lifting block 502. When the lifting block 502 descends, the lifting block 502 and the auxiliary block 9 abut against each other, and the trapezoidal block 11 on the lifting block 502 is inserted into the trapezoidal groove 10 on the auxiliary block 9. Since the terrain block and the trapezoidal groove 10 fit together, such a setting can improve the force strength of the lifting block 502 and prevent the top block 501 from shaking when the top block 501 clamps the cable.

[0040] As a preferred example, Figure 5 As shown, the base 4 of this embodiment is provided with a groove 12 in the same direction as the strip hole 7, and a conductive bar 13 is provided in the groove 12 to connect the two ends of the strip hole 7. Specifically, the groove 12 is provided around the inner wall of the strip hole 7, and the conductive bar 13 is laid in the groove 12. The arrangement of the groove 12 can ensure that the cable will not be affected when inserted into the strip hole 7, and the two ends of the cable inserted into the strip hole 7 are in contact with the conductive bar 13, and the conductive bar 13 can connect the two cables.

[0041] The cable butt joint in this embodiment ensures that water vapor cannot enter the cable in the joint through the coordinated arrangement of the sealing gasket 3 and the opening 2. The arrangement of the clamping assembly 5 ensures that two cables can be clamped at the same time by the clamping assembly 5, which facilitates the installation of the cables. The arrangement of the fastener 6 can improve the tightness of the clamping assembly 5, thereby preventing the cable from detaching from the joint. The arrangement of the conductive strip 13 ensures that the two cables can be connected. The arrangement of the outer shell 1 can improve safety.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
