Description

Technical Field

[0001] This utility model relates to the field of leakage current protection device technology, and in particular to an integrated multi-circuit leakage current protection device. Background Technology

[0002] Integrated multi-line leakage current protection devices, as core equipment for ensuring electrical safety, can simultaneously monitor and protect multiple power supply lines from leakage, greatly improving the integration level and space utilization of the power supply system.

[0003] Because multiple power supply wires of different types and purposes need to be connected, these wires are usually directly connected to the wiring ports of the protector. The lack of a dedicated organization, storage and guidance structure results in the wires being randomly distributed and tangled on the outer surface of the protector. This messy wiring method not only occupies a lot of space and poses serious safety hazards, but also makes the wire markings unclear. When the leakage current protector malfunctions and needs to be disassembled for repair, the staff has to spend a lot of time sorting out and identifying the corresponding circuit and connected equipment of each wire, which greatly reduces the repair efficiency and prolongs the fault handling time. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated multi-circuit leakage current protector, which solves the problem of excessive connecting wires on the outer surface of the leakage current protector, which leads to cumbersome subsequent disassembly and maintenance and poses a significant safety hazard.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: An integrated multi-circuit leakage current protector includes a housing. The leakage current protector body is detachably installed in the inner cavity of the housing. Multiple side plates are fixedly installed on the outer surface of the housing. Multiple insertion holes are opened on the top of the outer surface of the side plates. Multiple storage slots are opened in the middle of the outer surface of the side plates. A reset spring is fixedly installed at the bottom of the inner cavity of the storage slot. A winding block is fixedly installed on the other side of the reset spring. A pull ring is provided on the other side of the winding block. A front magnet is fixedly installed on the rear side of the winding block. A rear magnet is fixedly installed on the rear side of the inner cavity of the storage slot. Multiple strip grooves are opened at the bottom of the outer surface of the side plates. A folding rod is rotatably installed in the inner cavity of the strip groove. A guide tube is rotatably installed at one end of the folding rod through a round shaft. A rubber pad is fixedly installed on the inner wall of the guide tube. A spring clip is provided in the middle of the guide tube.

[0006] Preferably, a sealing sleeve is fixedly installed on the top of the inner cavity of the socket. The sockets are evenly distributed on the top of the outer surface of the sub-side plate. The position of the sockets matches the position of the wire mounting holes on the outer surface of the residual current device (RCD) body. Thus, in use, one end of other external connecting wires passes through the socket and extends into the inner cavity of the mounting hole on the outer surface of the RCD body, thereby connecting other electrical equipment and the RCD body. The sealing sleeve, in conjunction with the sealing sleeve, seals and protects the end of the connecting wire that extends into the socket.

[0007] Preferably, the side panels are fixedly installed on the left, rear and right sides of the housing. The surfaces of the side panels at different positions are coated with different colors of pigment. In use, the side panels at different positions and coated with different colors of pigment can be used to insert connecting wires of different types or connected to electrical equipment at different positions, thereby distinguishing different wires and facilitating subsequent maintenance and repair.

[0008] Preferably, the take-up block is movably mounted in the inner cavity of the storage slot via a return spring. The upper and lower sides of the inner cavity of the storage slot are arc-shaped. The length of the take-up block and the unstretched return spring combination matches the depth of the inner cavity of the storage slot. The front magnet and the rear magnet are installed in corresponding positions. Thus, in use, the take-up block is pulled out of the inner cavity of the storage slot by the pull ring, which makes it easy to wrap excess wire around the outer surface of the take-up block. After wrapping, the pull ring is released, and under the elastic force of the return spring, the take-up block automatically retracts into the inner cavity of the storage slot, thereby protecting the wire on the outer surface of the take-up block and preventing the wire from easily detaching from the outer surface of the take-up block.

[0009] Preferably, one end of the folding rod is rotatably connected to the inner wall of the strip groove, and the other end of the folding rod is rotatably connected to the guide tube through a round shaft. The folding rod can be completely retracted into the inner cavity of the strip groove. Therefore, during use, the telescopic design of the folding rod and the rotatable connection between the folding rod and the inner cavity of the strip groove make it easy to adjust the length and position of the folding rod according to the actual use.

[0010] Preferably, the rubber pad is fixedly installed on the inner wall of the guide tube and the inner wall of the spring clip. The upper and lower sides of the inner cavity of the rubber pad are arc-shaped. In use, the arc-shaped design of the upper and lower sides of the inner cavity of the rubber pad facilitates the insertion of the wire. Combined with the rubber material of the rubber pad and the spring clip set in the middle of the guide tube, the friction between the inserted wire and the outer surface of the wire is increased, preventing the wire from easily sliding in the inner cavity of the guide tube.

[0011] Compared with the prior art, the advantages of this utility model are as follows:

[0012] 1. This utility model utilizes the combined use of a winding block structure and a return spring structure. During operation, the folding rod is first stretched and the position of the guide tube is adjusted. Then, the wire is passed through the guide tube, and all excess wire is stretched to the storage groove. Next, the tension spring is stretched to move the winding block out and wrap the excess wire around the outer surface of the winding block. After completion, the pull ring is released, and the return spring force is used to retract the winding block into the inner cavity of the storage groove for protection. Finally, the wire plug is inserted into the socket and connected to the leakage current protector body. This achieves the effect of evenly placing the wire, facilitating subsequent daily maintenance of the leakage current protector, and improving the safety of use. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figures 1 to 4 This embodiment provides an integrated multi-circuit leakage current protector, including a housing 1. The leakage current protector body 2 is detachably installed inside the housing 1. Multiple side plates 3 are fixedly installed on the outer surface of the housing 1. The side plates 3 are fixedly installed on the left, rear and right sides of the housing 1. The surface of the side plates 3 at different positions is coated with different colors of pigment. In use, the side plates 3 at different positions and coated with different colors of pigment are used to insert different types of connecting wires or to electrical equipment at different positions, so as to distinguish different wires and facilitate subsequent maintenance and repair.

[0020] Multiple insertion holes 4 are provided on the top of the outer surface of the side plate 3. A sealing sleeve is fixedly installed on the top of the inner cavity of the insertion hole 4. The insertion holes 4 are evenly distributed on the top of the outer surface of the side plate 3. The position of the insertion holes 4 matches the position of the wire mounting hole on the outer surface of the leakage current protector body 2. Thus, when in use, one end of other external connecting wires passes through the insertion hole 4 and extends into the inner cavity of the mounting hole on the outer surface of the leakage current protector body 2, thereby connecting other electrical equipment and the leakage current protector body 2. With the cooperation of the sealing sleeve, the end of the connecting wire extending into the insertion hole 4 is sealed and protected.

[0021] Multiple storage slots 5 are provided in the middle of the outer surface of the side plate 3. A return spring 6 is fixedly installed at the bottom of the inner cavity of the storage slot 5. A winding block 7 is fixedly installed on the other side of the return spring 6. A pull ring 8 is provided on the other side of the winding block 7. A front magnet 9 is fixedly installed on the rear side of the winding block 7. A rear magnet 10 is fixedly installed on the rear side of the inner cavity of the storage slot 5. The winding block 7 is movably installed in the inner cavity of the storage slot 5 through the return spring 6. The upper and lower sides of the inner cavity of the storage slot 5 are arc-shaped. The length of the combination of the winding block 7 and the unstretched return spring 6 matches the depth of the inner cavity of the storage slot 5. The installation positions of the front magnet 9 and the rear magnet 10 are corresponding. In use, the winding block 7 is pulled out of the inner cavity of the storage slot 5 by the pull ring 8, which makes it easy to wind the excess wire around the outer surface of the winding block 7. After winding, the pull ring 8 is released. Under the elastic force of the return spring 6, the winding block 7 automatically retracts into the inner cavity of the storage slot 5, thereby protecting the wire on the outer surface of the winding block 7 and preventing the wire from easily falling off the outer surface of the winding block 7.

[0022] Multiple strip grooves 11 are provided at the bottom of the outer surface of the side plate 3. A folding rod 12 is rotatably installed in the inner cavity of the strip groove 11. One end of the folding rod 12 is rotatably connected to the inner wall of the strip groove 11, and the other end of the folding rod 12 is rotatably connected to the guide tube 13 through a round shaft. The folding rod 12 can be completely retracted into the inner cavity of the strip groove 11. Therefore, in use, the telescopic design of the folding rod 12 and the rotatable connection between the folding rod 12 and the inner cavity of the strip groove 11 make it easy to adjust the length and position of the folding rod 12 according to the actual use.

[0023] One end of the folding rod 12 is rotatably mounted with a guide tube 13 via a round shaft. A rubber pad 14 is fixedly installed on the inner wall of the guide tube 13. A spring clip 15 is set in the middle of the guide tube 13. The rubber pad 14 is fixedly installed on the inner wall of the guide tube 13 and the inner wall of the spring clip 15. The upper and lower sides of the inner cavity of the rubber pad 14 are arc-shaped. Therefore, when in use, the arc-shaped design of the upper and lower sides of the inner cavity of the rubber pad 14 facilitates the insertion of the wire. In combination with the rubber material of the rubber pad 14 and the spring clip 15 set in the middle of the guide tube 13, the friction between the wire and the outer surface of the wire is increased after insertion, preventing the wire from easily sliding in the inner cavity of the guide tube 13.

[0024] Working principle: First, assemble the entire structure correctly. Then, sort the wires and select the installation direction of the wires according to the type of wire or the location of the electrical equipment to which the wires are connected. Then, pass the wires one by one through the guide tube 13. When passing through the guide tube 13, press the spring clip 15 to open it to facilitate the passage of the wires. After all the wires have passed through the guide tube 13, release the spring clip 15. The friction between the wires inside the guide tube 13 and the inner wall of the guide tube 13 is increased by the spring clip 15 and the rubber pad 14, and the wires inside the guide tube 13 are clamped to prevent the wires from moving easily.

[0025] Then manually pull the pull ring 8 to move the winding block 7 out of the inner cavity of the storage slot 5. Next, wrap the excess part of the wire around the outer surface of the winding block 7. After all the wire is wrapped, release the pull ring 8. Under the elastic force of the return spring 6, the winding block 7 automatically retracts into the inner cavity of the storage slot 5, thereby protecting and fixing the wire on the outer surface of the winding block 7. Finally, insert one end of the wire into the socket 4 and connect it to the body 2 of the leakage current protector.

[0026] By assembling the wires that should be inserted at different side plates 3 on the outer surface of the outer casing 1 in the same way as described above, we can avoid the problem of wires being placed randomly, resulting in too many wires, which would affect the daily maintenance and repair during subsequent use and pose a significant safety hazard.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
