[0034] Applying the technical solution of this embodiment, the cable connection device includes a first mounting seat 10, a second mounting seat 20 and a protective tube 30. The first mounting seat 10 is used to fix the first cable 1. The first mounting seat 10 includes a mounting seat body 11, a driving structure 12 and a clamping structure 13.

Through the above-mentioned arrangement, the first mounting seat 10 can fix the first cable 1, and the second mounting seat 20 can fix the second cable 2, so that after the first cable 1 and the second cable 2 are connected, the relative position between the first cable 1 and the second cable 2 can be more stable. The mounting seat body 11 can support the driving structure 12 and the clamping structure 13. The driving structure 12 can drive the second ends of the plurality of clamping members 131 to move toward the direction close to the center of the avoidance opening 111 or toward the direction away from the center of the avoidance opening 111, so that the plurality of clamping members 131 can clamp the first cable 1 or the plurality of clamping members 131 can loosen the first cable 1. The avoidance opening 111 allows the first cable 1 to pass through the mounting seat body 11, so that the first cable 1 is connected to the second cable 2. The protective tube 30 can protect the first end of the first cable 1 and the second end of the second cable 2. Therefore, the technical solution of this embodiment effectively solves the problem of poor connection stability of the first cable 1 and the second cable 2 in the related art.

[0035] It should be noted that the structure of the second mounting seat 20 is the same as that of the first mounting seat 10. In this embodiment, the first cable 1 and the second cable 2 are both electrical cables.

The driving ring 121 can drive the multiple rotating shafts 1311 to rotate, and then the rotating shafts 1311 can drive the clamping plates 1312 to move when rotating, so that the free ends of the clamping plates 1312 can move toward the direction close to the center of the avoidance opening 111 to achieve the clamping of the first cable 1 by the multiple clamping plates 1312, or the free ends of the clamping plates 1312 can move toward the direction away from the center of the avoidance opening 111 to achieve the loosening of the first cable 1 by the multiple clamping plates 1312.

[0037] It should be noted that the number of the clamping members 131 in this embodiment is 10. The plurality of clamping members 131 are evenly arranged inside the driving ring 121. An insulating pad is arranged on one side of the clamping plate 1312 facing the center of the avoidance opening 111.

[0038] The cable connection device also includes a plurality of heat shrink tubes. A heat shrink tube is provided on the side of the first mounting seat 10 away from the second mounting seat 20.

A heat shrink tube is also provided on the side of the second mounting seat 20 away from the first mounting seat 10. By using a hot air gun, the heat shrink tube can be wrapped around the outer surface of the second cable 2 to achieve insulation protection.

[0039] Every two clamping plates 1312 are disposed on the outer wall of the rotating shaft 1311 in a staggered manner at different heights.

[0040] like Figures 3 to 5 As shown, in this embodiment, the clamping plate 1312 is arc-shaped, one of any two adjacent clamping plates 1312 is a first clamping plate, and the other is a second clamping plate, and the first clamping plate and the second clamping plate are stacked in the direction from the first mounting seat 10 to the second mounting seat 20. Through the above arrangement, the first clamping plate and the second clamping plate can clamp the first cable 1 more effectively, so that the position of the first cable 1 is more stable.

[0041] It should be noted that the 10 clamping members 131 of the first mounting seat 10 of the present embodiment are divided into a first clamping group, a second clamping group, a third clamping group, a fourth clamping group and a fifth clamping group which are arranged in sequence. The first clamping group, the second clamping group, the third clamping group, the fourth clamping group and the fifth clamping group each include two clamping members. The first clamping member in the first clamping group, the second clamping member in the first clamping group, the first clamping member in the second clamping group, the second clamping member in the second clamping group, the first clamping member in the third clamping group, the second clamping member in the third clamping group, the first clamping member in the fourth clamping group, the second clamping member in the fourth clamping group, the first clamping member in the fifth clamping group and the second clamping member in the fifth clamping group are arranged in sequence.

The first clamping member in the second clamping group, the first clamping member in the third clamping group, and the first clamping member in the fifth clamping group are located in the same plane on the side away from the second mounting seat. The above arrangement enables the clamping structure 13 to clamp the first cable 1 more stably and to clamp the first cable 1 at different positions.

[0042] like Figure 7 and Figure 8 As shown, in this embodiment, a plurality of driving teeth 1211 are arranged on the inner wall of the driving ring 121, a plurality of rotating shafts 1311 are arranged at intervals along the circumference of the driving ring 121, a plurality of transmission teeth 13111 are arranged on the rotating shaft 1311, and the driving teeth 1211 mesh with the transmission teeth 13111. The transmission teeth 13111 can mesh with the driving teeth 1211, and then when the driving ring 121 rotates, the plurality of rotating shafts 1311 can be driven to rotate simultaneously.

[0043] It should be noted that the driving structure 12 further includes a first driving screw, which is rotatably disposed on the mounting seat body 11 and is threadably engaged with the outer periphery of the driving ring 121. A plurality of rotating shafts 1311 are located inside the driving ring 121. The first driving screw is a worm, and the outer periphery of the driving ring 121 is a worm wheel.

[0044] like Figures 6 to 9As shown, in this embodiment, the first mounting seat 10 further includes a limiting seat body 14 and a plurality of abutting structures 15. The limiting seat body 14 is arranged on the side of the mounting seat body 11 facing the second mounting seat 20. A plurality of mounting holes 141 are arranged on the limiting seat body 14. The plurality of mounting holes 141 are arranged one by one corresponding to the plurality of wire cores 3 of the first cable 1. A abutting structure 15 is arranged in each mounting hole 141. The limiting seat body 14 can protect the first cable 1. The wire core 3 of the first cable 1 can pass through the mounting hole 141, which is convenient for connecting the wire core 3 of the first cable 1 with the second cable 2. The abutting structure 15 can limit the wire core 3 of the first cable 1, which is convenient for connecting the first cable 1 with the second cable 2.

[0045] It should be noted that the mounting hole 141 is a strip-shaped hole, which extends in a direction perpendicular to the axis of the wire core 3 .

[0046] like Fig. 9 As shown, in this embodiment, a plurality of abutting structures 15 are movably arranged on the limiting seat body 14, and each abutting structure 15 and the hole wall of the mounting hole 141 corresponding thereto jointly form a clamping channel 40 for clamping the wire core 3. The abutting structure 15 can move on the limiting seat body 14, so that the abutting structure 15 can clamp the wire core 3 together with the hole wall of the mounting hole 141, and fix the wire core 3 in the clamping channel 40, or the abutting structure 15 moves in a direction away from the wire core 3, so that the wire core 3 can move in the mounting hole 141.

[0047] like Fig. 9 As shown, in this embodiment, the abutting structure 15 includes an abutting plate 151 and an elastic reset member 152. The abutting plate 151 is movably arranged in the mounting hole 141 along a direction perpendicular to the axis of the mounting hole 141, and the elastic reset member 152 is arranged between the limiting seat body 14 and the abutting plate 151. The elastic reset member 152 can apply elastic force to the abutting plate 151, so that the abutting plate 151 can clamp the wire core 3 together with the hole wall of the mounting hole 141. When the abutting plate 151 moves in a direction away from the wire core 3, the elastic reset member 152 can make the abutting plate 151 move toward the wire core 3, so that the abutting plate 151 and the hole wall of the mounting hole 141 can clamp the wire core 3 together.

[0048] It should be noted that the surface of the side where the abutting plate 151 contacts the wire core 3 is an arc surface, and an insulating pad is also provided on the arc surface. A mounting groove is provided on the side of the mounting hole 141 away from the wire core 3, and an elastic reset member 152 is provided in the mounting groove. The abutting structure 15 also includes a connecting rod, the first end of which is movably provided in the mounting groove, and the second end of the connecting rod is connected to the abutting plate 151. A first stop plate is provided at the notch of the mounting groove, and a second stop plate is provided at the first end of the connecting rod. The first stop plate cooperates with the second stop plate to prevent the connecting rod from falling off the mounting groove. The elastic reset member 152 is provided between the side of the mounting groove away from the wire core 3 and the second stop plate.

[0049] The elastic reset member 152 comprises a compression spring. Of course, in other embodiments, the elastic reset member may also be a tension spring.

[0050] like Figure 1 As shown, in this embodiment, the cable connection device further includes a connection member 50, the first end of the protection tube 30 is connected to the first mounting seat 10, and the connection member 50 is connected between the second end of the protection tube 30 and the second mounting seat 20. The connection member 50 can connect the protection tube 30 with the second mounting seat 20, and the first end of the protection tube 30 is connected to the first mounting seat 10, so that the relative position of the first mounting seat 10 and the second mounting seat 20 can be stabilized, thereby making the connection between the first cable 1 and the second cable 2 more stable.

[0051] It should be noted that the protection tube 30 includes an insulating tube and a fixing plate arranged on a side of the insulating tube close to the second mounting seat 20, and the cable connection device also includes a mounting plate, which is arranged on a side of the second mounting seat 20 facing the first mounting seat 10, and the fixing plate and the insulating plate are connected by a connecting member 50. The connecting member 50 includes a connecting bolt.

[0052] like Figure 1 and Fig.10 As shown, in the present embodiment, the cable connection device further comprises a fixing member 60 and an anti-slip member 70 pivotally connected to the fixing member 60, the fixing member 60 is connected between the mounting seat body 11 and the external connection structure, and the anti-slip member 70 has an anti-slip outward swing position for preventing the fixing member 60 from falling off from the external connection structure and an avoidance recovery position for avoiding the external connection structure. The fixing member 60 can connect the mounting seat body 11 and the external connection structure. When the anti-slip member 70 is in the anti-slip outward swing position, the risk of the fixing member 60 being detached from the external connection structure can be reduced. When the anti-slip member 70 is in the avoidance recovery position, the anti-slip member 70 will not interfere with the movement of the fixing member 60.

[0053] like Fig.10 and Fig.11As shown, in this embodiment, the fixing member 60 includes a fixing nail 61, and a receiving space 611 is provided in the fixing nail 61. The anti-slip member 70 includes an anti-slip hook 71, and the anti-slip hook 71 is swingably provided in the receiving space 611. The fixing nail 61 is also provided with an avoidance groove 612 connected to the receiving space 611. When the anti-slip member 70 is switched from the avoidance recovery position to the anti-slip outward swing position, the anti-slip hook 71 extends out of the fixing nail 61 from the avoidance groove 612. Through the above arrangement, the anti-slip hook 71 can be connected to the fixing nail 61, so that the anti-slip hook 71 can be switched between the avoidance recovery position and the anti-slip outward swing position.

[0054] The external connection structure may be soil, or may be a structure matching the structure of the anti-detachment hook 71 .

[0055] It should be noted that the second mounting seat 20 is also provided with a fixing member 60 and an anti-slip member 70. Preferably, the first mounting seat 10 is provided with fixing members 60 and anti-slip members 70 on both sides in the direction from the first mounting seat 10 to the second mounting seat 20, and the second mounting seat 20 is also provided with fixing members 60 and anti-slip members 70 on both sides in the direction from the first mounting seat 10 to the second mounting seat 20.

[0056] The anti-slip component 70 also includes a second driving screw and a driving block that cooperates with the second driving screw. A connecting hole is also provided on the fixing nail. The second driving screw is threadedly matched with the connecting hole. The middle part of the anti-slip hook 71 is hingedly connected to the side wall of the avoidance groove 612. The first end of the anti-slip hook 71 is hingedly connected to the side of the driving block away from the second driving screw. When the second driving screw rotates, it can drive the driving block to move toward the bottom of the fixing nail 61, and then the driving block can drive the second end of the anti-slip hook 71 to extend out of the avoidance groove, that is, the anti-slip hook 71 moves to the anti-slip outward swing position.

[0057] The beneficial effects of the technical solution of this embodiment are as follows:

[0058] 1. The first driving screw is rotated to drive the driving ring 121 to rotate, and the rotation of the driving ring 121 can drive the rotating shaft 1311 to rotate, and then the rotating shaft 1311 can drive the clamping plate 1312 to rotate, so that the free ends of the multiple clamping plates 1312 can clamp the first cable 1, so that the position of the first cable 1 is tightened. In addition, the multiple clamping members 131 of this embodiment can clamp the first cables 1 of different diameters, so that the versatility of the clamping structure 13 is better, avoiding the problem that the clamping structure in the traditional cable connection device cannot adapt to the first cables of different diameters, resulting in the inability to clamp the first cable.

[0059] 2. The elastic potential energy of the elastic reset member 152 drives the abutting plate 151 to move toward the wire core 3 along the mounting hole 141, so that the wire core 3 is clamped between the abutting plate 151 and the hole wall of the mounting hole 141, so that the first cable 1 is not easy to shake when connected, which facilitates the connection of the first cable 1 and the second cable 2. After the first cable 1 and the second cable 2 are connected, the relative position between the first cable 1 and the second cable 2 can be more stable.

[0060] 3. The first mounting seat 10 and the second mounting seat 20 are separately arranged, so that the staff can easily observe the connection status of the first cable 1 and the second cable 2, and then fix the fixing plate and the mounting plate by connecting bolts, and further close the protection tube 30 to protect the connection between the first cable 1 and the second cable 2. Compared with the traditional device, the device can protect the first cable 1 and the second cable 2 by the protection tube 30, and fix the threads between the fixing plate and the mounting plate by connecting bolts, and the bolts can be turned to open the protection tube 30, and the first cable 1 and the second cable 2 inside it can be inspected, thereby improving the inspection and maintenance efficiency of the staff.

[0061] The use process of the cable connection device of this embodiment is as follows:

[0062] When the first cable 1 and the second cable 2 need to be connected, the staff first strips the first cable 1 and the second cable 2 at the joint to expose the wire core 3 on the outside, and then respectively passes one end of the first cable 1 and the second cable 2 through the heat shrink tube, and makes the first cable 1 located inside the first mounting seat 10 and the second cable 2 located inside the second mounting seat 20, and then passes the wire core 3 through the mounting hole 141, and twists the wire core 3 of the first cable 1 and the wire core 3 of the second cable 2 together, and wraps them with electrical tape or insulating tape, and then the staff rotates the first driving screw of the first mounting seat 10, and the rotation of the first driving screw drives the driving ring 121 to rotate, and the rotation of the driving ring 121 drives the rotating shaft 1311 to rotate, and the rotation of the rotating shaft 1311 can drive the clamping plate 1312 to rotate, and at this time the clamping plate 1312 can abut against the first cable 1 to tighten the position of the first cable 1 to prevent The first cable 1 shakes to improve the stability of the connection, and then the first driving screw of the second mounting seat 20 is rotated. The rotation of the first driving screw of the second mounting seat 20 drives the driving ring 121 to rotate. The rotation of the driving ring 121 drives the rotating shaft 1311 to rotate. The rotation of the rotating shaft 1311 can drive the clamping plate 1312 to rotate. At this time, the clamping plate 1312 can abut against the second cable 2 to tighten the position of the second cable 2 to prevent the second cable 2 from shaking and improve the stability of the connection. Secondly, the staff abuts the fixing plate and the mounting plate at one end of the protective tube 30 against each other, and rotates the connecting bolt so that the connecting bolt passes through the fixing plate and is located inside the mounting plate to complete the installation of the protective tube 30. At this time, the protective tube 30 will protect the joint between the first cable 1 and the second cable 2. Finally, the staff uses a hot air gun to fit the two sets of heat shrink tubes to the outer walls of the first cable 1 and the second cable 2 respectively to achieve insulation protection.

[0063] When docking the core 3 of the first cable 1 and the core 3 of the second cable 2, the staff lifts the top plate 151 upwards, and passes the core 3 of the first cable 1 through the mounting hole 141 of the first mounting seat 10 and the core 3 of the second cable 2 through the mounting hole 141 of the second mounting seat 20. Then the staff releases the top plate 151. At this time, the elastic potential energy of the elastic reset member 152 drives the top plate 151 to move toward the core 3, so that the core 3 is clamped between the hole wall of the mounting hole 141 and the top plate 151. At this time, the staff twists the core of the first cable 1 and the core of the second cable 2 together, wraps them with electrical tape or insulating tape, and completes the docking.

[0064] Finally, after the first cable 1 and the second cable 2 are connected, the staff can fix the first mounting seat 10 through the fixing piece 60. After the fixing is completed, the staff moves the anti-detachment hook 71 to the anti-detachment outward swing position, so that the anti-detachment hook 71 is connected to the external connection structure, avoiding the separation of the fixing piece 60 from the external connection structure, and improving the fixing stability of the first mounting seat 10 and the second mounting seat 20.
