Description

Technical Field

[0001] This utility model relates to the field of substation technology, specifically a quick-plug connection structure for an explosion-proof substation module. Background Technology

[0002] Traditional substation module connections typically employ bolting or welding for electrical connections. While these methods are robust, they are extremely inconvenient in scenarios requiring frequent module replacement or maintenance. Particularly in explosion-proof substation environments, where stringent safety and sealing requirements necessitate careful installation and removal, traditional methods can damage the original explosion-proof structure, increasing safety hazards. Furthermore, traditional connection methods are time-consuming, impacting work efficiency and failing to meet the demands of modern power systems for rapid response and efficient maintenance. Therefore, developing a safe and convenient quick-plug connection structure is crucial for improving the operational efficiency and safety of explosion-proof substations. Utility Model Content

[0003] The purpose of this invention is to provide a quick-plug connection structure for an explosion-proof substation module to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a quick-plug connection structure for an explosion-proof substation module, comprising plug-in terminals and fixed terminals. A connecting collar is fixedly connected to the outer wall of the plug-in terminal near the fixed terminal. Two plug-in connecting blocks are fixedly connected to the two side walls of the connecting collar near the plug-in terminal. A plug-in limiting block is fixedly connected to the outer wall of the two plug-in connecting blocks away from the connecting collar. A fixed collar is fixedly connected to the outer wall of the fixed terminal near the plug-in terminal. Limiting holes are provided on the side walls of the fixed collar that match the positions of the two plug-in connecting blocks. The two plug-in limiting blocks are inserted into the limiting holes.

[0005] As a further embodiment of this utility model: the outer walls of the two fixed collars that match the positions of the limiting holes are each provided with a releasable limiting button, and the ends of the two releasable limiting buttons near the limiting holes are releasable from the insertion and removal limiting block.

[0006] As a further embodiment of this utility model: the fixed terminal includes an outer isolation covering layer, and an insertion groove is fixedly connected to the inner wall of the outer isolation covering layer near the insertion terminal, and the insertion groove is through-hole at the end near the insertion terminal.

[0007] As a further improvement of this utility model: a fixed wire core is fixedly connected to the inner wall of the plug-in slot, and the end of the fixed wire core away from the plug-in terminal is arranged to extend outward.

[0008] As a further embodiment of this utility model: the inner wall of the plug-in terminal is fixedly connected with a plug-in wire core, the inner wall of the plug-in wire core is hollow, and the plug-in wire core is inserted and connected to the plug-in slot.

[0009] As a further improvement of this utility model, a fixing flange is fixedly connected to the outer wall of the fixed terminal at the end away from the plug-in terminal.

[0010] Compared with existing technologies, the advantages of this utility model are as follows: By using pluggable and fixed terminals, along with pluggable limit blocks and releaseable limit buttons, this utility model enables rapid connection and disconnection of modules, significantly shortening assembly and disassembly time and improving work efficiency. The explosion-proof design, with its outer insulating coating, effectively prevents explosive gases or dust from entering the connection structure, ensuring the safe operation of the substation. Simultaneously, the snap-fit ​​design of the pluggable limit blocks and releaseable limit buttons ensures the stability of the connection.

[0011] The insertion and connection of the plug-in conductors into the plug slots, combined with the sealing effect of the outer insulating sheath, effectively prevents the influence of external media on the electrical connection, improving the stability and durability of the connection. This connection structure is suitable for various specifications of explosion-proof substation modules, has good versatility and interchangeability, and reduces maintenance costs.

[0018] Please see Figures 1-4 In this embodiment of the utility model, a quick-plug connection structure for an explosion-proof substation module includes a plug-in terminal 1 and a fixed terminal 2.

[0019] A connecting collar 3 is fixedly connected to the outer wall of the plug-in terminal 1 near the fixed terminal 2. Two plug-in connecting blocks 31 are fixedly connected to each of the two side walls of the connecting collar 3. A plug-in limiting block 32 is fixedly connected to the end of the plug-in connecting block 31 away from the connecting collar 3.

[0020] A fixing collar 4 is fixedly connected to the outer wall of the fixed terminal 2 near the plug-in terminal 1. A limiting hole 41 is opened on the side wall of the fixing collar 4 that matches the position of the plug-in connection block 31. The plug-in limiting block 32 is inserted and connected to the limiting hole 41.

[0021] A releasable limit button 42 is also provided through the outer wall of the fixed collar 4. The end of the releasable limit button 42 near the limit socket 41 can be released from the insertion limit block 32.

[0022] The fixed terminal 2 includes an outer isolation covering layer 24. The inner wall of the outer isolation covering layer 24 near the plug-in terminal 1 is fixedly connected to a plug-in groove 23. The inner wall of the plug-in groove 23 is fixedly connected to a fixed wire core 22.

[0023] The inner wall of the plug-in terminal 1 is fixedly connected with a plug-in wire core 11, and the plug-in wire core 11 is inserted into the plug-in slot 23.

[0024] A fixing flange 21 is fixedly connected to the outer wall of the fixed terminal 2 away from the plug-in terminal 1, which is used to install the fixed terminal 2 on the substation module.

[0025] In practical applications, the plug-in terminal 1 is aligned with the fixed terminal 2, so that the plug-in limiting block 32 is inserted into the limiting socket 41, and at the same time the plug-in wire core 11 is inserted into the plug-in slot 23 to complete the electrical connection.

[0026] When it is necessary to disconnect, press the release limit button 42 to release the plug-in limit block 32 from the release limit button 42, and then pull out the plug-in terminal 1.

[0027] The working principle of this utility model is as follows: During connection, the plug-in terminal 1 is mechanically engaged with the fixed collar 4 and the limiting insertion hole 41 on the fixed terminal 2 through the plug-in connecting block 31 and plug-in limiting block 32 on the connecting collar 3, ensuring the stability of the connection. At the same time, the plug-in wire core 11 in the plug-in terminal 1 is electrically connected with the plug-in groove 23 and the fixed wire core 22 in the fixed terminal 2 to realize the transmission of electrical energy.

[0028] During disassembly, pressing the releasable limit button 42 on the retaining collar 4 releases the insertion / removal limit block 32 from the releasable limit button 42, allowing the insertion / removal terminal 1 to be pulled out from the retaining terminal 2. This design ensures both the stability of the connection and facilitates quick assembly and disassembly, improving work efficiency and safety.
