Description

Technical Field

[0001] The utility model relates to the technical field of cable branching, in particular to a high-voltage cable branching box which is convenient for assembly and disassembly. Background Art

[0002] A cable junction box is a device used to branch, connect and convert cable lines. It is mostly used outdoors. Cable junction boxes are divided into two categories according to their electrical structure: one category does not contain any switching equipment, and the box only has accessories for processing and connecting the cable ends. It has a relatively simple structure, a small size, and a single function. It can be called an ordinary junction box; the other category is that the box not only has the accessories of an ordinary junction box, but also contains one or more switching devices. It has a relatively complex structure, a large size, many connecting devices, and is difficult to manufacture with high cost. It can be called an advanced junction box.

[0003] The cable junction box is a very important facility in electrical equipment. However, the cable junction box currently used does not have a dust-proof device inside. When some of the internal wiring terminals are not in use, dust is easily accumulated and the wiring ports may be blocked, resulting in poor contact when wiring.

[0004] For example, in the high-voltage cable junction box disclosed in Chinese patent CN218449439U, the cover is opened, and the cover is connected to the box body by a hinge. When the cover is opened, the gas spring inside it will extend and support the cover to prevent the cover from falling. The wiring terminal is moved out from the inside of the protective groove, and the wiring terminal moves around the rotating shaft until one side of the wiring terminal is attached to the pad to support the wiring terminal. At this time, the wiring port is exposed and wiring can be carried out. This device can prevent the wiring port from being exposed to the outside when the wiring terminal is not in use, thereby effectively preventing dust from entering the wiring port.

[0005] However, the lower end of the junction box is not provided with a disassembly and assembly mechanism, so it is difficult to disassemble and inspect or move to other working positions after being fixed on the ground.

[0006] For this reason, we urgently need to provide a high-voltage cable distribution box that is convenient for disassembly and assembly. Utility Model Content

[0007] The utility model aims to provide a high-voltage cable junction box which is easy to disassemble and assemble, so as to solve the problem in the above background technology that the lower end of the junction box is not provided with a disassembly mechanism, so that it is difficult to disassemble for maintenance or move to other working positions after being fixed on the ground.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-voltage cable junction box that is easy to disassemble and assemble, comprising a base and a junction box, the base being fixed on the ground, the junction box being connected to the upper end of the base, the upper end of the base being connected to a mounting mechanism, the mounting mechanism comprising a disassembly unit and a wiring unit, the disassembly unit being arranged at the upper end of the base, and the wiring unit being arranged at the lower end of the junction box.

[0009] The disassembly and assembly unit includes a first spring, an insertion rod and a pull rod, wherein the first spring is connected to the inside of the base, the insertion rod is fixedly connected to one end of the first spring, and the pull rod is fixedly connected to one end of the upper side of the insertion rod close to the first spring.

[0010] A further improvement is that a mounting groove is provided in the middle position of the upper end of the base, and rectangular grooves are symmetrically provided inside the base at the left and right ends of the mounting groove, one end of the first spring away from the insertion rod is fixedly connected to the end of the inner side of the rectangular groove away from the mounting groove, and the outer side of the insertion rod is slidably connected to the inner side of the rectangular groove, so that when the first spring bounces, the insertion rod can be driven to slide along the inner side of the rectangular groove.

[0011] A further improvement is that a sliding groove is provided inside the base at the upper end of the rectangular groove, and insertion holes are provided at the left and right ends of the lower interior of the junction box. The inner side of the outer sliding groove of the pull rod is slidably connected, and the outer side of the end of the insertion rod away from the first spring is plugged into the inner side of the insertion hole, so that the junction box can be fixed to the installation groove at the upper end of the base by inserting the end of the insertion rod away from the first spring into the insertion hole.

[0012] A further improvement is that the wiring unit includes a sealing plate, a sponge block, an interface, a fixed frame, a second spring and a baffle, the sealing plate is connected to the front end of the branch box, the sponge block is connected to the upper end of the sealing plate, the interface is fixedly connected to the middle position on the left side of the inner front end of the branch box, the fixed frame is connected to the outer end of the branch box, the second spring is fixedly connected to the inner rear end of the fixed frame, and the baffle is fixedly connected to the front end of the second spring.

[0013] A further improvement is that the upper side of the fixed frame is fixedly connected to the outside of the junction box below the interface, and the outer side of the baffle is slidably connected to the inner side of the fixed frame, so that when the second spring bounces, the baffle can be driven to slide along the inner side of the fixed frame.

[0014] A further improvement is that a connecting groove is provided inside the junction box below the front end of the interface, the outer side of the sealing plate is slidably connected to the inner side of the connecting groove, and the lower end of the sealing plate abuts against the upper end of the baffle plate, so that after the sealing plate is slid into the connecting groove and is located at the front end of the interface, the baffle plate is pushed forward by the second spring rebound, so that the front end of the baffle plate is located at the lower end of the sealing plate, thereby fixing the sealing plate to the front end of the interface.

[0015] A further improvement is that a through hole is opened at the upper end of the sealing plate, and the lower end of the sponge block is fixedly connected to the inner bottom end of the through hole, so that after the interface is wired, the data line can be located in the through hole through the expansion and contraction of the sponge block, so that the interface remains closed after wiring.

[0016] In summary, the present application discloses a high-voltage cable distribution box that is easy to disassemble and assemble.

[0017] The technical solution places the lower end of the junction box in the installation groove, and then pushes the insertion rod through the rebound of the first spring so that the end of the insertion rod away from the first spring is inserted into the insertion hole, so that the junction box can be fixed to the installation groove at the upper end of the base, and the installation of the junction box is completed. Then, by pulling the pull rod to the left and right ends to drive the insertion rod to move until it is no longer located in the insertion hole, the junction box can be removed from the upper end of the base, so that the junction box can be conveniently and quickly disassembled and assembled through the disassembly and assembly unit.

[0018] Furthermore, after the sealing plate is slid into the connecting groove and is located at the front end of the interface, the baffle is pushed forward by the second spring rebound so that the front end of the baffle is located at the lower end of the sealing plate. The sealing plate can be fixed to the front end of the interface to protect the interface and play a dust-proof role, effectively preventing dust from entering the wiring port.
