[0001] This utility model relates to the field of voltage switching equipment technology, specifically a modular voltage switching device that can be quickly plugged in and unplugged. Background Technology

[0002] In power electronic equipment, voltage switching devices are key components for achieving different voltage outputs. With the continuous development of power systems and the diversification of application scenarios, higher requirements are placed on the flexibility, convenience and reliability of voltage switching devices.

[0003] Currently, common modular voltage switching devices on the market often require plugging and unplugging multiple voltage modules one by one, which is cumbersome, time-consuming, and prone to asynchronous plugging and unplugging, affecting the normal operation and efficiency of the equipment. In addition, existing plug-in connectors may misalign the plugs during the plugging and unplugging process, resulting in damage to the plug core. Therefore, this utility model proposes a modular voltage switching device that can be quickly plugged and unplugged to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a modular voltage switching device that can be quickly plugged in and out, in order to solve the problems mentioned in the background art.

[0006] The main body of the device is equipped with multiple sets of voltage module groups;

[0007] The quick-connection mechanism includes several sets of locking pins, which are installed below the fixed plate. The fixed plate is mounted on the adjusting plate by a spring. An adjusting handle is provided in the middle of the fixed plate. The adjusting handle passes through the adjusting plate. Both ends of the adjusting plate are slidably installed in the guide grooves formed by the outer shell of the device body.

[0008] The plug-in connector is provided with a slot that matches the locking pin. When multiple plug-in connectors are inserted into the voltage module group terminal, the locking pin is moved to the slot directly below by sliding the adjustment plate and pulling the adjustment handle. The adjustment handle is then released, the locking pin is inserted into the slot, and the adjustment handle is pressed and pushed to realize the synchronous insertion and removal of the plug-in connectors.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 4 This utility model provides a technical solution: a modular voltage switching device that can be quickly plugged in and out, including a device body 1, voltage module groups 2, plug-in connectors 3, and a quick plug-in connection mechanism 4; the device body 1 is provided with multiple voltage module groups 2; the quick plug-in connection mechanism 4 includes several sets of locking pins 41, which are installed below a fixed plate 42. The fixed plate 42 is installed on an adjusting plate 45 by a spring 43. An adjusting handle 44 is provided in the middle of the fixed plate 42, which passes through the adjusting plate 45. The two ends of the adjusting plate 45 are slidably installed in the guide groove formed by the outer shell of the device body 1; the plug-in connector 3 is provided with a slot 31 that matches the locking pins 41. When multiple plug-in connectors 3 are inserted into the ends of the voltage module groups 2, the locking pins 41 are moved to the slot 31 directly below by sliding the adjusting plate 45 and lifting the adjusting handle 44. The adjusting handle 44 is released, and the locking pins 41 are inserted into the slot 31. Pressing and pushing the adjusting handle 44 realizes the synchronous plugging and unplugging of the plug-in connectors 3.

[0024] The quick-connection mechanism 4 enables the simultaneous insertion and removal of multiple plug-in connectors 3. Operators only need to slide the adjustment plate 45, pull and push the adjustment handle 44 to make the locking pin 41 accurately engage with the slot 31 on the plug-in connector 3. This avoids the tedious operation of traditional plugging and removing one by one, greatly improves the voltage module switching efficiency, and saves operation time.

[0025] Please see Figures 1 to 4 The plug-in connector 3 has a guide block 32 integrally formed on one end, and the guide block 32 is adapted to the limiting groove 12 on the outer shell of the main body 1 of the device.

[0026] Please see Figures 1 to 4 The outer shell of the main body 1 of the device is provided with multiple sets of partitions 13. Several sets of voltage module groups 2 are arranged at intervals through multiple sets of partitions 13. The partitions 13 can define independent installation space for the voltage module groups 2. During maintenance, only the fixing screws of the corresponding modules need to be loosened, without disassembling adjacent parts.

[0027] Please see Figures 1 to 4Guide posts 46 are inserted into the guide groove of the outer shell of the main body 1. The two ends of the adjusting plate 45 pass through the guide posts 46 in the guide grooves on both sides and are connected to them. One end of the guide post 46 is provided with a threaded structure 461. The guide post 46 is installed in the guide groove of the outer shell of the main body 1 in a spiral manner through the threaded structure 461 at the end.

[0028] During installation, the threaded connection allows the guide post 46 to be accurately fixed in the predetermined position within the guide groove, ensuring the straightness and stability of the two ends of the adjustment plate 45 as they slide along the guide post 46. This effectively prevents the adjustment plate 45 from shifting or getting stuck during the sliding process, and ensures the precise alignment of the locking pin 41 with the slot 31, thus improving the reliability of the insertion and removal operation.

[0029] Please see Figures 1 to 4 The locking pin 41 is connected to a stud 411 at the end. The locking pin 41 is installed below the adjusting plate 45 through the stud 411 at the end. During long-term use, the locking pin 41, as a component that frequently participates in the insertion and removal action, may wear or be damaged. After using the stud 411 for connection, it is not necessary to disassemble the entire quick insertion and removal connection mechanism 4. The damaged locking pin 41 can be replaced separately by simply unscrewing the stud 411, which reduces maintenance costs and time.

[0030] In use, align the multiple plug-in connectors 3 with the ends of the multiple voltage module groups 2 on the main body 1. Since the guide blocks 32 on the end of the plug-in connectors 3 are adapted to the limiting grooves 12 on the outer shell of the main body 1, the guide blocks 32 can slide along the limiting grooves 12, playing a guiding role and helping the plug-in connectors 3 to be accurately inserted into the ends of the voltage module groups 2. At this time, slide the adjusting plate 45. The two ends of the adjusting plate 45 slide along the guide groove formed by the outer shell of the main body 1. At the same time, the adjusting plate 45 moves on the guide post 46. Then, pull the adjusting handle 44 upward. The adjusting handle 44 drives the fixing plate 42 to move upward. The spring 43 under the fixing plate 42 is compressed, causing the locking pin 41 under the fixing plate 42 to move upward and lock the plate. When the fixed pin 41 moves to the position directly below the slots 31 of the multiple plug-in connectors 3, the adjusting handle 44 is released, and the compressed spring 43 returns to its original shape, generating a downward force that pushes the fixed plate 42 and the locking pin 41 below it downward. Several sets of locking pins 41 are inserted into the slots 31 of the corresponding plug-in connectors 3. When plugging or unplugging is required, the adjusting handle 44 is pressed, causing the adjusting handle 44 to move the fixed plate 42 and the locking pin 41 as a whole. At the same time, the adjusting handle 44 is pushed horizontally outward. Under the action of the locking pins 41, the multiple plug-in connectors 3 are simultaneously pulled out of the voltage module group 2. Conversely, by operating the adjusting handle 44 in the opposite direction, the multiple plug-in connectors 3 can be simultaneously inserted into the voltage module group 2.

[0031] 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.
