DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] Reference Figure 1-7 , the utility model is used to disclose a cable wiring device.

[0029] For details, please refer to Figure 1-3 :

[0030] The invention comprises a first sleeve 1, a second sleeve 2, a plug 9 and a slot 11. The second sleeve 2 is threadedly connected to the inside of the first sleeve 1. The length of the device can be changed by twisting the first sleeve 1 and the second sleeve 2. One end of the first sleeve 1 is fixedly connected to the first fixing seat 4. The material of the first fixing seat 4 is ceramic or plastic. The plug 9 is located at the axial position of the limit sleeve 8. One end of the plug 9 is fixedly connected to the inside of the first fixing seat 4 and passes through the first fixing seat 4. The first fixing seat 4 is used to fix the plug 9 and play an insulating role. The slot 11 is located at the axial position of the second sleeve 2. The plug 9 and the slot 11 are made of copper and the surface is silver-plated. An isolation sleeve 13 is provided between the slot 11 and the second sleeve 2. The isolation sleeve 13 is made of rubber and is used to provide elastic force to the surface of the slot 11 and can effectively insulate. One end of the second sleeve 2 is fixedly connected to the second fixing seat 5. The material of the second fixing seat 5 is ceramic or plastic. One end of the slot 11 is fixedly connected to the second fixing seat 5 and passes through the second fixing seat 5. The second fixing seat 5 is used to fix the slot 11 and play an insulating role. The plug 9 is inserted into the interior of the slot 11 to electrically connect the plug 9 and the slot 11.

[0031] When wiring, separate the first sleeve 1 and the second sleeve 2, connect the plug 9 and one end of the slot 11 to the port where the cable is disconnected, respectively, and then screw the second sleeve 2 into the first sleeve 1 through a thread, so that the plug 9 is inserted into the slot 11, so that the cable forms a passage. By twisting the first sleeve 1 and the second sleeve 2 to change the length of the device, the length of the cable can be adjusted, which can minimize the change in the overall length of the cable after wiring.

[0032] The surface of the second sleeve 2 is threadedly connected with a push ring 6, and the other end of the first sleeve 1 is fixedly connected to a limiting sleeve 8, which is used to limit the first waterproof ring 7 and prevent the first waterproof ring 7 from direct contact with the outside world, thereby improving the service life of the first waterproof ring 7. One side of the push ring 6 is located on the surface of the second sleeve 2 and is slidably connected to the first waterproof ring 7. The material of the first waterproof ring 7 is silicone, and one side of the push ring 6 is used to be slidably connected to the inside of the first waterproof ring 7;

[0033] After adjusting the length of the cable, twist the push ring 6 to move it toward the direction close to the first sleeve 1, drive the first waterproof ring 7 to move toward the direction close to the limiting sleeve 8, insert it into the inside of the limiting sleeve 8, twist the second sleeve 2 with force to squeeze the first waterproof ring 7, so that the first waterproof ring 7 is deformed inside the limiting sleeve 8, and fills the gap between the first sleeve 1 and the second sleeve 2, which can effectively prevent water from entering the first sleeve 1 and the second sleeve 2, thereby improving the service life of the device;

[0034] A plurality of protrusions 10 are provided on the surface of the plug 9. The protrusions 10 are arc-shaped rings that are higher in the middle and lower on both sides. The protrusions 10 and the plug 9 are an integrated structure. A plurality of dividing grooves 12 are evenly distributed on the side of the slot 11. The slot 11 is divided into multiple parts by the dividing grooves 12 to increase the elastic deformation ability of the slot 11. When the plug 9 is inserted into the slot 11, the inner wall of the slot 11 is squeezed by the protrusions 10, causing the slot 11 to undergo elastic deformation, thereby increasing the contact stability between the slot 11 and the plug 9. The isolation sleeve 13 then applies an inward elastic force to the slot 11, which can further increase the stability of the electrical connection between the slot 11 and the plug 9.

[0035] See Figure 4-7 In another embodiment:

[0036] It also includes two connecting sleeves 18, which are respectively fixedly connected to one side of the second fixing seat 5 and the first fixing seat 4, and are located on the outside of the wiring port 16. The outside of the connecting sleeve 18 is threadedly connected to the dust cover 3, and the connecting sleeve 18 and the dust cover 3 are used to isolate the wiring port 16 from the outside. The inside of the connecting sleeve 18 and one side of the wiring port 16 are plugged with a second waterproof ring 14, and a gasket 15 is provided between the second waterproof ring 14 and the wiring port 16. The gasket 15 can make the second waterproof ring 14 more evenly stressed when squeezed. One end of the inner wall of the dust cover 3 is fixedly connected to a pressure ring 19, which is used to be plugged into one end of the connecting sleeve 18;

[0037] As can be seen from the above structural design, before connecting the cables, the two dust covers 3 are removed and respectively put on the ports where the cables are disconnected, and then the conductor part of the cable is fixed inside the wiring port 16. The dust cover 3 is twisted to move the dust cover 3 in the direction close to the first sleeve 1 and the second sleeve 2, thereby driving the pressure ring 19 to move and inserting the pressure ring 19 into the interior of the connecting sleeve 18, thereby squeezing the second waterproof ring 14, causing the second waterproof ring 14 to deform, thereby filling the gap between the second waterproof ring 14 and the cable insulation layer, which can effectively prevent rainwater from entering the interior of the dust cover 3 and improve the stability of the device.

[0038] It also includes two wiring ports 16, which are respectively located on one side of the second fixing base 5 and the first fixing base 4. The wiring ports 16 are respectively fixedly connected to the protrusion 10 and one end of the slot 11 by bolts. The interior of the wiring ports 16 is connected to a pressing block 20 that slides up and down. The top of the pressing block 20 is rotatably connected to a threaded column 17. The threaded column 17 is threadedly connected to the wiring port 16. The top of the threaded column 17 is provided with a hexagonal countersunk hole. The pressing block 20 and the wiring port 16 are both conductors and are electrically connected to the slot 11 and the plug 9.

[0039] As can be seen from the above structural design, when in use, the conductor of the cable is inserted into the interior of the wiring port 16, and the threaded column 17 is screwed downward using a tool, driving the pressing block 20 to move downward, pressing the cable conductor, thereby fixing the cable.

[0040] From the above, we can know that:

[0041] The present invention addresses the technical problem that the existing patents cannot adjust the length of the cables when connecting them, which is very inconvenient during use. The present invention adopts the technical solutions of the above embodiments. At the same time, the implementation process of the above technical solutions is as follows:

[0042] Technical principle: When in use, when wiring, separate the first sleeve 1 and the second sleeve 2, remove the two dust covers 3, and put them on the ports where the cables are disconnected, insert the conductor of the cable into the interior of the wiring port 16, use a tool to twist the threaded column 17 downward, and drive the pressure block 20 to move downward, compress the cable conductor, thereby fixing the cable, twist the dust cover 3, and move the dust cover 3 in the direction close to the first sleeve 1 and the second sleeve 2, drive the pressure ring 19 to move, and insert the pressure ring 19 into the interior of the connecting sleeve 18, thereby squeezing the second waterproof ring 14, causing the second waterproof ring 14 to deform, thereby filling the gap between the second waterproof ring 14 and the cable insulation layer, which can effectively prevent rainwater from entering the interior of the dust cover 3;

[0043] Then, the second sleeve 2 is screwed into the interior of the first sleeve 1 through a thread, and the plug 9 is inserted into the interior of the slot 11, so that the cable forms a passage. By twisting the first sleeve 1 and the second sleeve 2, the length of the device is changed, thereby adjusting the length of the cable, which can minimize the change in the overall length of the cable after wiring;

[0044] After adjusting the length of the cable, twist the push ring 6 to move it toward the direction close to the first sleeve 1, drive the first waterproof ring 7 to move toward the direction close to the limiting sleeve 8, insert it into the inside of the limiting sleeve 8, twist the second sleeve 2 with force to squeeze the first waterproof ring 7, so that the first waterproof ring 7 is deformed inside the limiting sleeve 8, and fills the gap between the first sleeve 1 and the second sleeve 2, which can effectively prevent water from entering the first sleeve 1 and the second sleeve 2, thereby improving the service life of the device;

[0045] Through the above configuration, this application can certainly solve the above technical problems and achieve the following technical effects:

[0046] By screwing the second sleeve 2 into the interior of the first sleeve 1 and inserting the plug 9 into the interior of the slot 11, a passage is formed for the cable. By twisting the first sleeve 1 and the second sleeve 2 to change the length of the device, the length of the cable is adjusted, which can minimize the change in the overall length of the cable after wiring.

[0047] By twisting the push ring 6, it moves toward the direction close to the first sleeve 1, squeezing the first waterproof ring 7, causing the first waterproof ring 7 to deform inside the limiting sleeve 8, filling the gap between the first sleeve 1 and the second sleeve 2, and effectively preventing water from entering the first sleeve 1 and the second sleeve 2, thereby improving the service life of the device.
