As shown in fig. 4, guide grooves 21 extending to the side doors 8 are provided on the top and bottom walls of the main body 1. The terminal plate 7 is slidably connected to the guide groove 21. When operations such as maintenance and the like are required, the wiring board 7 can be pulled to slide outwards along the guide groove 21, which is beneficial to facilitating the operations such as maintenance and the like. When the maintenance operation is completed, the terminal block 7 is pushed to slide inward along the guide groove 21, thereby facilitating the operation. Meanwhile, the guide groove 21 can play a role in fixing and limiting the position of the wiring board 7, and the structure is simplified.

In a specific embodiment, in order to ensure that the wiring board 7 slides smoothly along the guide groove 21, protruding strips 22 for cooperating with the guide groove 21 may be further protrudingly provided at both top and bottom ends of the wiring board 7. This arrangement can reduce the contact area of the terminal plate 7 with the guide groove 21, thereby reducing friction and ensuring smooth sliding. Preferably, the end of the protruding strip 22 facing away from the side door 8 is small in width relative to the end close to the side door 8. The arrangement is such that the relatively inner protruding strip 22 is in a clearance fit with the guide groove 21, and the relatively outer protruding strip 22 is in a closer fit with the guide groove 21. This arrangement ensures stable connection of the terminal block 7 to the main body 1 while ensuring smooth sliding of the terminal block 7 with respect to the guide groove 21.

In addition, in order to ensure stable connection between the side door 8 and the main body 1 and prevent accidental opening, a latch mechanism may be provided therebetween.

As shown in fig. 4 and 5, specifically, the latch mechanism includes a fixed bar 19, a fixed plate 10, a support plate 14, a reset member 12, a rotational bar 15, a bar 16, and a reset torsion spring (not shown in the drawings). Wherein, the fixed barrier strip 19 is arranged on the bottom wall of the main body 1 and is of a strip-shaped structure. The fixing plate 10 is fixedly disposed on the side door 8, and is of a strip plate structure, and forms a general cantilever structure after being fixed. The supporting plate 14 is disposed opposite to the fixing plate 10, and has substantially the same structure as the fixing plate 10. Meanwhile, the support plate 14 is configured to be relatively slidably coupled with respect to the fixing plate 10. A reset member 12 is disposed between the support plate 14 and the fixing plate 10 for actuating the reset of the support plate 14. For example, the restoring member 12 may be a spring located between the fixing plate and the supporting plate. The rotating barrier 15 is hinged at the free end of the support plate 14 and is used for forming a clamping fit with the fixed barrier 19. The setting of pin 16 protrudingly is in keeping away from of fender rotation blend stop 15 the end of side door 8 for it is spacing to rotate blend stop 15, prevents to rotate blend stop 15 and continue to rotate and the unstability that forms at the joint in-process. The reset torsion spring is arranged between the rotating barrier strip 15 and the supporting plate 14 and is used for ensuring the reset of the rotating barrier strip 15.

As shown in fig. 6, during the closing of the side door, the swing bar 15 approaches the fixed bar 19 along with the side door 8, and after the swing bar 15 contacts the fixed bar 19, the swing bar 15 is urged to rotate relative to the support plate 14 as the side door 8 continues to close. With the side door 8 continuing to be closed, the rotary blocking strip 15 rotationally crosses the fixed blocking strip 19 from outside to inside and reaches the clamping position, and at the moment, under the action of the reset torsion spring, the rotary blocking strip 15 returns to the clamping position to form clamping connection with the fixed blocking strip 19. In addition, due to the arrangement of the stop lever 16, when the side door 8 is pulled, the stop lever 16 prevents the rotation stop strip 15 from rotating, and therefore stable clamping of the side door 8 and the main body 1 is guaranteed.

The through-nails 11 pass through the supporting plate 14 in a clearance manner and then are fixed with the fixing plate 10. Meanwhile, one end of the through nail 11 is provided with a limiting piece 13 abutted against the side wall of the support plate 14 so as to prevent the through nail 11 from falling off relative to the support plate 14. Wherein, the reset piece 12 is sleeved on the outer wall of the through nail 11.

To disengage the rotating bar 15 from the fixed bar 19, the support plate 14 can be actuated to move along the piercing pin 11, as shown in fig. 7. The support plate 14 moves the rotating barrier 15 so that the rotating barrier 15 is dislocated to release the engagement of the rotating barrier 15 with the fixed barrier 19. At this time, the side door 8 can be pulled open. After no force is applied to the support plate 14, the support plate 14 can be reset by the reset member 12.

When needs are installed, maintained or detected inside, through pulling handle 4 for handle 4 drives cabinet door 3 and rotates. The support plate 14 is then pushed so that the swing bar 15 is released from the restriction of the fixed bar 19, and the side door 8 is pushed, whereby the side door 8 can be opened. Then, the wiring board 7 is moved to pull out the wiring board 7 from the inside of the main body 1, thereby facilitating observation of the inside of the main body and facilitating installation and maintenance.

After the completion of the maintenance work, the terminal block 7 is pushed back to the inside of the main body 1, and then the side door 8 is turned. When one end of the side door 8 is close to the main body 1, the side door 8 is tightly attached to the main body 1 under the action force of the magnetic strip 9. Meanwhile, the side door 8 drives the small supporting plate 14 and the like to move, so that the rotating barrier strip 15 is in contact with the fixed barrier strip 19 and the rotating barrier strip 15 rotates, and then after the fixed barrier strip 19 is separated from the rotating barrier strip 15, the rotating barrier strip 15 falls back under the action of self gravity and the reset torsion spring, so that the rotating barrier strip 15 is connected with the fixed barrier strip 19 in a clamping manner. At this time, the rotation bar 15 is restricted by the bar 16 to prevent the rotation bar 15 from rotating continuously, so that the side door 8 is locked by the latch mechanism.
