Description

Technical Field

[0001] The utility model relates to the technical field of railway communication, in particular to a railway communication cable box. Background Art

[0002] Railway communication cable boxes include cable boxes, branch cable boxes and intermediate cable boxes. Specifically, the cable box is a box for cable lead-out, lead-in, branching and jointing; the branch cable box is usually installed at the cable branch point to divide several core wires of a cable into cable boxes for each branch cable; the intermediate cable box is a cable box that can lead to equipment and pass cables.

[0003] However, the existing cable boxes cannot lock the positions of the connected cable ends, resulting in that when two or more cables are connected, the connected ends of the cables are easily detached from the cable box, making cable connection difficult and time-consuming. To this end, we propose a railway connection cable box that can save cable connection time. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 4 The utility model provides a technical solution: a railway communication cable box, comprising a lower box body 1 and a box cover 2, one end of the box cover 2 is rotated to cover the top of the lower box body 1, a metal ring 7 is fixed to the inner bottom of the lower box body 1, a metal conduction rod 13 is welded to one side of the metal ring 7, one end of the metal conduction rod 13 is welded and fixed to a wiring frame 9, a grounding terminal 8 is welded to one side of the metal ring 7, and the grounding terminal 8 is connected to a wall or underground, which can drain the leakage current to the underground to avoid leakage of the lower box body 1 or the box cover 2.

[0022] The lower box body 1 and the box cover 2 are both made of insulating material. A wiring frame 9 is fixed to the inner bottom of the lower box body 1. The wiring frame 9 is a "mouth"-shaped hard frame with a through hole in the middle. A pressing rod 10 is threadedly connected to the top of the wiring frame 9. The lower end of the pressing rod 10 applies pressure to the surface of the wire 16 passing through the wiring frame 9, which can prevent the wire 16 from moving inside the wiring frame 9. A first wire inlet tube 14 is provided on one side of the lower box body 1 opposite to the opening of the wiring frame 9. The first wire inlet tube 14 is used to limit the surface of the wire 16 so that the wire 16 passes through the interior of the lower box body 1. A second wire inlet tube 17 is penetrated and connected to the other side of the lower box body 1 relative to the side where the first wire inlet tube 14 is located.

[0023] Wires 16 are passed through the first and second inlet pipes 14 and 17 , respectively. Limiting tubes 15 are threadedly connected to the surfaces of the first and second inlet pipes 14 and 17 . The limiting tubes 15 can prevent the wires 16 from shifting at the connection with the lower box body 1 .

[0024] Preferably, Figure 2 As shown, a closed frame 3 is welded on one side of the box cover 2, and the closed frame 3 is tangent to the inner wall of the lower box body 1. Threaded holes 4 are respectively opened on one side of the lower box body 1 and the box cover 2. Screws adapted to the threaded holes 4 can be used to fix the lower box body 1 and the box cover 2.

[0025] Preferably, Figure 1 As shown, a fixing hole 5 is opened on the inner wall of the lower box body 1, and the fixing hole 5 includes a screw hole and a limiting recess. The limiting recess passes through the screw hole coaxially, and the diameter of the limiting recess is larger than the aperture of the screw hole. After the screw is connected to the fixing hole 5, the force-applying end of the screw can be accommodated by the limiting recess.

[0026] Preferably, Figure 1 As shown, a through hole 6 is formed on one side of the lower box body 1 opposite to the fixing hole 5. The through holes 6 are opposite to the fixing hole 5 and the number of the through holes 6 is equal to the number of the fixing holes 5. The through holes 6 can improve the convenience of connecting the fixing hole 5 with the screw.

By using screws that match the fixing holes 5, the fixing strength of the lower box body 1 can be further strengthened. When connecting the cables, the wires 16 to be connected are respectively passed through the first inlet tube 14 and the second inlet tube 17 into the lower box body 1 and the wiring frame 9. The part of the wire 16 that passes through the wiring frame 9 applies pressure to the surface of the wire 16 through the lower end of the pressing rod 10, so that the connecting end of the wire 16 is limited in the lower box body 1, freeing the hands of the connection personnel, facilitating the connection of the wire 16, and reducing the convenience of connecting different wires 16. By fixing the metal ring 7 welded to the surface of the wiring frame 9 and the grounding terminal 8 inside the lower box body 1, the risk of electric shock on the surface of the lower box body 1 and the box cover 2 after the wire 16 leaks can be avoided, thereby improving the safety of the cable box.
