Description

Technical Field

[0001] This application relates to the field of busbar technology, and more particularly to busbars with dustproof joints. Background Technology

[0002] Busbar trunking is a closed metal conductor device that collects and distributes electrical energy. It consists of conductive bars, insulating materials, and a metal shell. It replaces traditional cables to achieve high current transmission and is widely used in power distribution scenarios such as buildings and industrial plants. It has advantages such as large current carrying capacity, flexible wiring, and convenient maintenance. It can adapt to complex power distribution needs and improve the reliability of power supply systems.

[0003] Chinese Patent No. CN222072709U discloses a busbar trunking with a dustproof connector, relating to the field of power transmission technology. This invention includes a first busbar trunking and a second busbar trunking. The protective mechanism includes a first protective shell and a second protective shell. Baffles are provided on both sides of the first protective shell. Mounting slots are provided on both sides of the first and second busbar trunkings. Limiting blocks are provided inside both the first and second protective shells. This invention, through the first and second protective shells and the fixing of the limiting blocks, improves the sealing performance of the connector. This improved sealing further prevents external factors such as dust and moisture from entering the busbar trunking. The baffles are located between the first and second protective shells, and their main function is to block the gap between them, which is a potential dust entry point. This effectively prevents dust from entering the busbar trunking through this gap.

[0004] However, in the aforementioned patent, when the first and second protective shells are used to seal the connection joint of the busbar trunking with dustproof seal, bolts are required to connect the first and second protective shells to the busbar trunking. This makes the installation and fixing process cumbersome, and subsequent maintenance and repair will also be difficult to disassemble, thus failing to achieve the effect of quick assembly and disassembly. Therefore, to solve the above problems, we provide a busbar trunking with a dustproof joint. Utility Model Content

[0005] The purpose of this invention is to provide a busbar trunking with a dustproof connector to solve the problems mentioned in the background art.

[0006] The embodiments of this application adopt the following technical solutions: A busbar trunking with a dustproof connector includes two busbar trunking bodies. Two dustproof shells are shared on the exterior of the two busbar trunking bodies. Two sliding covers and two locking seats are fixedly connected to the outer surfaces of the two dustproof shells, respectively. A tension spring is fixedly connected to the inner wall of each sliding cover. A sliding plate is fixedly connected to one end of each tension spring. A locking plate is hinged to one side of each sliding plate via a pin. A locking protrusion is provided on one side of each locking plate. A locking groove is formed on one side of each locking seat. The outer surface of the locking protrusion is in close contact with the inner wall of the locking groove. A detachable handle is fixedly connected to the upper surface of the locking plate.

[0007] Preferably, two positioning blocks are fixedly connected to the outer surfaces of the two busbar trunking bodies, and two positioning sleeves are fixedly connected to the outer surfaces of the two dustproof shells, with the outer surfaces of the positioning blocks in contact with the inner walls of the positioning sleeves.

[0008] Preferably, each of the two dustproof shells has a strip groove on one side that is close to each other, and the inner wall of each of the two strip grooves is provided with a strip dustproof pad. The two strip dustproof pads are in contact on one side that is close to each other. A dustproof sealing layer is fixedly connected to one side that is close to each other, and the two dustproof sealing layers are in contact with the outer surface of the busbar trunking on one side that is close to each other.

[0009] Preferably, two grooves are formed on the upper surface of both dustproof shells, and two aluminum alloy heat dissipation strips are fixedly embedded on the outer surface of both busbar grooves.

[0010] Preferably, a connector is provided between the two dustproof shells, and conductive bars are provided at both ends of the two busbar trunking bodies, with the ends of the two conductive bars that are close to each other extending into the interior of the connector.

[0011] The above-described technical solutions adopted in the embodiments of this application can achieve the following beneficial effects: This busbar trunking with dustproof connectors allows the positioning sleeve of the dustproof housing to quickly align and fit into the positioning block of the busbar trunking after the busbar's conductive busbar is connected to the connector. This alignment can be completed without the need for bolts. Additionally, pulling the disassembly handle stretches and stores the tension spring inside the sliding cover. After flipping the locking plate and releasing the handle, the tension spring resets, causing the locking protrusion to engage with the locking slot, thus locking the two dustproof housings securely to the outside of the connector. During maintenance, the two dustproof housings can be quickly disassembled by reversing the operation. The entire process requires no tools, solving the problem of the cumbersome installation and disassembly operations of traditional dustproof housings that require bolt connections. This device achieves rapid disassembly and assembly through an elastic locking and positioning structure, improving operational efficiency. Attached Figure Description

A locking groove 9 is provided on one side of the locking seat 4. The outer surface of the locking protrusion 8 is in close contact with the inner wall of the locking groove 9, locking the trunking. The upper surface of the locking plate 7 is fixedly connected with a disassembly handle 10; specifically, the busbar trunking 1 provides an installation carrier for conductive components, the dust cover 2 provides protection for its joints, the sliding cover 3 provides installation space for the tension spring 5 and the sliding plate 6, the tension spring 5 can stretch and store force and reset, and can provide elastic driving force for locking, the sliding plate 6 drives the locking plate 7 to move, the locking protrusion 8 of the locking plate 7 cooperates with the locking groove 9 of the locking seat 4 to achieve quick locking, the disassembly handle 10 makes it easy for the operator to pull the locking plate 7, and locking and unlocking can be completed by flipping, without the need for bolts or tools, simplifying the disassembly and assembly operation.

[0017] In this embodiment, two positioning blocks 11 are fixedly connected to the outer surfaces of the two busbar trunking bodies 1, and two positioning sleeves 12 are fixedly connected to the outer surfaces of the two dustproof shells 2. The outer surfaces of the positioning blocks 11 are in contact with the inner walls of the positioning sleeves 12. Two grooves 13 are formed on the upper surfaces of the two dustproof shells 2. Two aluminum alloy heat dissipation strips 14 are fixedly embedded on the outer surfaces of the two busbar trunking bodies 1. A connector 19 is provided between the two dustproof shells 2. Conductive bars 15 are provided at both ends of the two busbar trunking bodies 1. The ends of the two conductive bars 15 that are close to each other extend into the interior of the connector 19. Specifically, the positioning blocks 11 cooperate with the positioning sleeves 12 of the dustproof shells 2 to achieve quick and accurate alignment of the dustproof shells 2, avoiding installation misalignment that affects the protective effect. The grooves 13 of the dustproof shells 2 are easy to disassemble and remove. The aluminum alloy heat dissipation strips 14 of the busbar trunking bodies 1 have high thermal conductivity and can quickly conduct operating heat to ensure equipment stability. The connector 19 realizes the docking of the conductive bars 15 of the two busbar trunking bodies 1, which can provide a reliable interface for power transmission and ensure smooth current transmission.

[0018] In this embodiment, each of the two dustproof shells 2 has a strip groove 17 on one side that is close to each other. The inner wall of each of the two strip grooves 17 is provided with a strip dustproof pad 18. The two strip dustproof pads 18 are in contact on one side that is close to each other. A dustproof sealing layer 16 is fixedly connected to one side that is close to each other on one side of the two dustproof shells 2. The two dustproof sealing layers 16 are in contact with the outer surface of the busbar trunking 1. Specifically, the strip grooves 17 provide installation and fixing space for the strip dustproof pads 18. The two strip dustproof pads 18 fit tightly together, preventing dust from entering from the joint gap of the dustproof shells 2. The dustproof sealing layer 16 fits the surface of the busbar trunking 1, filling the gap between the dustproof shells 2 and the busbar trunking 1, forming a dustproof barrier, improving protection reliability, preventing dust from entering the joint and affecting the contact performance of the conductive busbar 15, and adapting to dusty environments.

[0019] Working principle: During installation, align the conductive bars 15 of the two busbar trunking bodies 1 with the connectors 19 and then place two dustproof shells 2 on the joints of the busbar trunking bodies 1. Align the positioning sleeves 12 of the dustproof shells 2 with the positioning blocks 11 of the busbar trunking bodies 1 to achieve quick positioning of the dustproof shells 2. Then, pull the disassembly handle 10 on the dustproof shells 2 to move the locking plate 7 and the sliding plate 6, causing the tension spring 5 inside the sliding cover 3 to stretch and store force. After pulling to a suitable distance, flip the locking plate 7 so that the locking protrusion 8 is aligned with the locking seat 4 of the other dustproof shell 2. Slowly release the disassembly handle 10, and the tension spring 5 returns to its original position, pulling the sliding plate 6 and causing the locking protrusion 8 to engage with the locking slot 9, completing the quick locking of the two dustproof shells 2. No bolts are required for fixing, improving installation efficiency. After locking, the strip dustproof pads 18 in the strip grooves 17 of the two dustproof shells 2 fit tightly together, and the dustproof sealing layer 16 contacts the outer surface of the busbar trunking 1, forming a double dustproof seal to prevent dust from entering the joint. The aluminum alloy heat dissipation strips 14 of the busbar trunking 1 accelerate the dissipation of heat generated during operation. During maintenance, simply pull the disassembly handle 10 to stretch the tension spring 5, flip the locking plate 7 to disengage the locking protrusion 8 from the locking slot 9, and the two dustproof shells 2 can be quickly disassembled. When removing the dustproof shells 2, the positioning sleeve 12 slides along the positioning block 11 to ensure smooth disassembly, solving the problems of troublesome operation and inconvenient maintenance of traditional bolt connections.
