Description

Technical Field

[0001] The present invention relates to the technical field of cable junction boxes, and particularly to a cable junction box. Background Art

[0002] The main functions of a cable junction box are to connect and protect cables. It can reliably connect the core wires of multiple cables together to achieve circuit conduction and ensure the stable transmission of electricity or signals. At the same time, the junction box provides a closed space for cable connection, which can prevent foreign matters such as dust and moisture in the outside world from entering, avoid the core wires of the cables from getting damp, short-circuited or corroded, thereby extending the service life of the cables. In addition, it can protect operators from electric shock hazards, playing a role in insulation and safety protection, and is an important component to ensure the safe and stable operation of the cable system.

[0003] During the use of existing cable junction boxes, the junction box is connected to the cable core wires through terminal blocks or terminal posts. When connecting the cable core wires, due to the limited size of the junction box and the large number of internal circuits in the junction box, it is time-consuming and laborious for workers to check or repair the inside of the junction box. Moreover, the cable core wires are wound around the outside of the terminal post. As the use time extends, the wound cable core wires will gradually spread to both sides, resulting in the gradual detachment between the cable core wires and the terminal post, thus affecting the normal transmission of current.

[0004] In view of the above problems, a cable junction box is proposed. Summary of the Invention

[0007] The terminal post includes bottom rings. The bottom rings are located at both ends of the terminal post. A round hole penetrates through the upper bottom ring. A winding body is arranged on the lower side of one side of the terminal post. The winding body is connected to a rotating ring on one side. The rotating ring is movably sleeved on the middle and lower part of the terminal post. The rotating ring is rotationally connected to the top of the terminal post through a telescopic rod above.

[0008] Furthermore, a splicing plate is installed at intervals inside the housing, and two insertion plates are provided on both sides above the splicing plate. Grooves are opened on both sides above the splicing plate, and the grooves are arranged above the inside of the housing. The bottom of the splicing plate is obliquely connected with a connecting plate, and one end of the connecting plate is fixedly connected to the edge of the chassis.

[0009] Furthermore, the splicing plate is located in the middle of the square groove inside the housing, and a waterproof shell is provided on one side of the inner wall of the housing, and a square groove is also reserved inside the waterproof shell.

[0010] Furthermore, a shell cover is provided above the housing, and the shell cover seals the upper part of the housing through the magnetic attraction ring at the edge. An insertion wire tube penetrates straight through the inside of the housing, and a cable body is arranged inside the insertion wire tube. An insertion post block is provided above the insertion wire tube, and a round hole is arranged inside the insertion post block.

[0011] Furthermore, a connecting column connected to the shell base is provided at the bottom of the central ring. A side plate is provided on one side of each chassis, and a notch for equipment splicing is provided on the opposite side of the side plate. The wiring posts are installed at intervals above the chassis through the bottom ring at the bottom end.

[0012] Furthermore, a sealing ring is provided inside the shell cover, and an insertion post penetrating through the inside of the insertion post block is provided at the lower end of the shell cover. A plurality of isolation plates are provided below the shell cover.

[0013] Furthermore, the winding body includes a cable groove penetrating through the inside. A connecting plate connected to the rotating ring is provided on one side above the winding body, and a handle is provided on the opposite side of the connecting plate. A wire clamping groove is provided above the winding body. A telescopic column is movably connected to the middle and lower part of the wiring post, and the telescopic column is located below the rotating ring. The top of the telescopic rod moves annularly inside the rod groove. The rod groove is arranged inside the upper bottom ring.

[0014] Furthermore, the isolation plates are located on the sides of the wiring posts, and the isolation plates correspond to the edges of each chassis up and down.

[0015] Furthermore, the winding body moves up and down outside the wiring post through the rotating ring and the telescopic rod. Threads are provided at the top of the wiring post, and the handle corresponds to the position of the round hole inside the upper bottom ring.

[0019] 2. When the cable junction box is in use, a shell cover is installed above the shell. A sealing ring is arranged at the connection between the shell cover and the shell. The sealing ring can prevent external moisture from entering the inside of the shell and play a moisture-proof role for the internal cable. Moreover, an isolation plate is connected below the shell cover, and the isolation plate isolates each group of terminal posts, which can prevent electromagnetic interference and ensure the data transmission of the cable;

[0020] 3. When assembling the cable junction box, a winding body is arranged on one side of the terminal post. The cable is inserted into the inside of the cable body for fixation. And the cable body moves circularly outside the terminal post through the setting of the rotating ring and the telescopic rod, so that the cable core is wound around the outside of the terminal post through the setting of the winding body. The quick installation of the cable core can be realized, and at the same time, the winding body is fixed through the setting of inserting the handle into the round hole inside the bottom ring. At the same time, the winding body is tightened and fixed through the thread above the terminal post, so that the cable core is always wound and bound on one side of the terminal post, which can prevent the cable core from loosening and falling off later and the situation of unstable current transmission.

And the rotating ring 81 is rotatably connected to the top of the terminal post 8 through the upper telescopic rod 84.

[0048] In the above invention, the terminal 8 is fixedly installed above the chassis 7 through the bottom ring 82 at the lower end, and a rotating ring 81 is sleeved below the middle of the terminal 8. One side of the rotating ring 81 is fixedly connected to the winding body 83. The winding body 83 rotates and rises outside the terminal 8 through the rotating ring 81. When the winding body 83 rotates, the cable passing through the inside can be wound around the outside of the terminal 8 to bundle and fix the cable and the terminal 8.

[0049] Preferably, as shown in Figure 8 the winding body 83 includes a cable groove 85 passing through the inside, and a connecting plate 87 connected to the rotating ring 81 is arranged on one side above the winding body 83.

[0053] The cable is wound around the outside of the terminal 8, and the cable is inserted into the cable groove 85 inside the winding body 83. The cable is fixedly wound around the outside of the terminal 8 by the clockwise rotation of the winding body 83 and the swivel 81. During maintenance, the handle 88 on one side of the winding body 83 is taken out from the circular hole inside the bottom ring 82, and then the wound cable is removed from the outside of the terminal 8 by the reverse rotation, and the cable is replaced. During replacement, multiple groups of terminal posts 8 are assembled together, and a chassis 7 is correspondingly arranged below each group of terminal posts 8. The chassis 7 can be separated by the side panels 73 and the notches 74 on the sides. After the chassis 7 is separated, the corresponding terminal posts 8 and the splicing plate 11 can also be separated, and the terminal posts 8 can be checked separately. The lines of the separate terminal posts 8 are simple and clear, which improves the maintenance efficiency of the staff. Finally, the cable is wound around the outside of the terminal post 8 again by the winding body 83, the swivel 81 and the telescopic rod 84, so that the cable is fixed on the outside of the terminal post 8 to prevent the cable from loosening.
