[0024] The following is combined with Figure 1 -Attached Figure 4 This application is described in further detail.

[0025] The embodiment of the present application discloses a cable connection device that is easy to maintain, including a box body 10 for protecting the cable connection. The box body 10 has openings at both ends and is hollow inside. A window is provided on one side of the box body 10. The box body 10 has a cavity inside for installing the cable. The cavity, the opening and the window of the box body 10 are connected. The openings at both ends of the box body 10 can extend two cables to be connected respectively. The two cables to be connected enter the cavity in the box body 10 through the openings at both ends of the box body 10 and are connected to form a cable connection point.

[0026] A guide rail 20 is provided in the cavity of the box body 10, and the central axis of the guide rail 20 is perpendicular to the central axis of the box body 10. A hollow installation cylinder 30 is provided on the guide rail 20. Two cables to be connected enter the cavity in the box body 10 through the openings at both ends of the box body 10 and then extend into the installation cylinder 30 for connection, that is, the connection point of the cable is located inside the installation cylinder 30. The installation cylinder 30 is also used to install a detection component. A groove for installing the detection component is opened on the installation cylinder 30. The detection component for detecting the working status of the cable connection can be installed outside the groove of the installation cylinder 30;

[0027] The side of the installation tube 30 close to the window of the box body 10 is fixedly connected to the connecting rod 31, and the end of the connecting rod 31 away from the installation tube 30 is fixedly connected to the sealing door 40, which is located outside the box body 10. The length and width of the sealing door 40 are greater than the length and width of the window of the box body 10. The sealing door 40 is used to close the window of the box body 10;

[0028] The guide rail 20 is provided with a locking member 21 for locking the installation cylinder 30. When the sealing door 40 closes the window of the box body 10 and the installation cylinder 30 is locked by the locking member 21, the locking position of the installation cylinder 30 deviates from the central axis of the box body 10 and is away from the sealing door.

[0029] The following is a further introduction based on specific usage scenarios.

[0030] When in use, the operator passes the two cables to be connected through the openings at both ends of the box body 10 respectively. After entering the box body 10, the two cables are connected in the installation cylinder 30 to form a cable connection point. At this time, the locking piece 21 locks the position of the installation cylinder 30, so that the installation cylinder 30 is in a locked state. In this case, the installation cylinder 30 is away from the central axis of the box body 10 in the direction away from the window of the box body 10. In this way, the position of the installation cylinder 30 is away from the window of the box body 10, which reduces the influence of the external environment of the box body 10 on the cable connection and improves the working stability of the cable connection.

[0031] When the operator needs to inspect the detection component outside the installation cylinder 30, there is no need to disassemble the box body 10, and only needs to pull the sealing door 40 outward. As the sealing door 40 moves away from the box body 10, the installation cylinder 30 connected to the sealing door 40 through the connecting rod 31 will also move synchronously with the sealing door 40. As the operator increases the force to pull the sealing door 40 outward, the installation cylinder 30 will overcome the locking of its position by the locking piece 21 and continue to move outward. When the installation cylinder 30 moves to the maximum stroke of the guide rail 20, it stops moving. At this time, the installation cylinder 30 and its detection component are located on the inside of the window and exposed to the operator, and the operator can carry out maintenance work.

[0032] Of course, when the installation cylinder 30 and its detection component are located on the inside of the window and are not sufficient for the operator to carry out maintenance work, the operator can continue to pull the sealing door outward to cause the installation cylinder 30 to break away from the restraint of the guide rail 20. Since the installation cylinder 30 is the connection point of the two cables, the two cables will limit and pull the position of the installation cylinder 30 to prevent the installation cylinder 30 from being out of the control of the power line. After the operator completes the maintenance work, the installation cylinder 30 is placed back on the guide rail 20, and then moves in the direction close to the window of the box body 10 until the sealing door 40 closes the window of the box body 10. At this time, the installation cylinder 30 is locked by the locking piece 21.

[0033] It can be seen that during the entire maintenance process, the operator saves the work of disassembling and reassembling the box body 10, thereby improving the efficiency of the maintenance work.

[0034] In general, in the embodiment of the present application, the detection component is installed on the outside of the installation tube 30 by cooperating with the sealing door 40, the connecting rod 31 and the installation tube 30. When the device needs to be maintained, the operator does not need to disassemble the box body 10, but only needs to pull the sealing door 40 outward to extend the installation tube 30. The operator saves the work of disassembling and reinstalling the box body 10, thereby improving the efficiency of the maintenance work.

[0035] As a feasible specific implementation method of the embodiment of the present application, the cavity of the box body 10 includes two parts, including an avoidance cavity 11 and a placement cavity 12 whose central axes are parallel to each other. The central axis of the placement cavity 12 is not colinear with the central axis of the box body 10. The avoidance cavity 11 is used to place the installation cylinder 30 and the cable connection point when the installation cylinder 30 is in a locked state. The avoidance cavity 11 is away from the window of the box body 10. When the sealing door 40 closes the window of the box body 10 and the installation cylinder 30 is locked by the locking piece 21, the locking position of the installation cylinder 30 is located in the placement cavity 12.

[0036] In combination with a specific usage scenario, when in use, the connection point of the cable is located inside the mounting cylinder 30, and the locking position of the mounting cylinder 30 is located in the avoidance cavity 11, which is away from the window of the box body 10. In this way, the external environment affects the mounting cylinder 30, the cable connection point, and the distance length of various detection components installed on the mounting cylinder 30, thereby reducing the impact of the external environment on the mounting cylinder 30, the cable connection point, and various detection components installed on the mounting cylinder 30, and significantly improving the service life of the device and its ability to resist harsh usage environments.

[0037] When the connection point of the cable is in the installation barrel 30, the cable needs to be bent after entering the box body 10. In a possible implementation method of the embodiment of the present application, two groups of winding posts 13 are arranged in the avoidance cavity 11 of the box body 10. The two groups of winding posts 13 are respectively arranged at one end of the avoidance cavity 11 close to the opening of the box body 10. The cable entering the box body 10 is bent by contacting and clinging to the pillar. After the rigid limit of the pillar, the bent cable enters the installation barrel 30 for connection, which increases the total length of the cable inside the box body 10, making the inside of the box body 10 The cable state can adapt to the displacement of the installation tube 30. Furthermore, the number of winding poles 13 in a group is two. One of the two winding poles 13 belonging to the same group is close to the central axis of the box body 10, and the other winding pole 13 is close to the window of the box body 10 and away from the central axis of the box body 10. The cable entering the box body 10 is bent twice. In addition to further improving the redundancy of the cable inside the box body 10, the same cable is in close contact with the two pillars of the same group. The friction between the cable and the pillars can improve the stability of the cable during installation.

[0038] As a feasible specific implementation method of the embodiment of the present application, the installation cylinder 30 can slide on the guide rail 20. The installation cylinder 30 is installed with a slider 32. The slider 32 is U-shaped. The U-shaped slider 32 opening is downwardly sleeved on the guide rail 20. The installation cylinder 30 is slidably connected to the top of the guide rail 20 through the slider 32. The operator can check the part that needs to be inspected by pulling the installation cylinder 30, without the need to disassemble the box body 10 as a whole, which significantly improves the overall efficiency of the operator in maintaining the cable connection device.

[0039] In a feasible implementation method of the embodiment of the present application, the locking member 21 includes a spring piece 22 installed on the guide rail 20, and the spring piece 22 has an arc-shaped protrusion 23. The arc-shaped protrusion 23 has a tendency to stick to the rail under the elastic force of the spring piece 22. When the arc-shaped protrusion 23 contacts the rail and there is no external stress applied to the mounting tube 30, the arc-shaped protrusion 23 and the spring piece 22 will confine the mounting tube 30 to a locked position. When the operator applies force to pull the mounting tube 30 outward, the slider 32 at the bottom of the mounting tube 30 pushes the arc-shaped protrusion 23 and the spring piece 22 out of the locked position.

[0040] As a feasible specific implementation method of the embodiment of the present application, the sealing door 40 has a sealing ring 41 and a buckle 42 on the side close to the box body 10, and the box body 10 has a snap-on seat adapted to the snap-on 42. The sealing door 40 is detachably connected to the outside of the box body 10 through the snap-on 42. After the operator completes the maintenance, the sealing door 40 and the box body 10 can be tightly connected together through the matching setting of the snap-on 42 and the snap-on seat, which reduces the time for the operator to reinstall and significantly improves the overall efficiency of the operator in maintaining the cable connection device.

[0041] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
