[0028] From the above description, it can be seen that the beneficial effects of the utility model are: the structure of the junction box is simple and novel, the terminal block 1 and the shell 2 are detachably connected through the locking structure 5, and when the personnel operate the locking structure 5, the locking structure 5 can be locked and unlocked without using tools. Therefore, the disassembly and assembly operation of the junction box structure is very convenient.

[0029] Furthermore, the locking structure 5 further includes an arc-shaped arm 55 , and the connecting piece 52 is connected to the locking piece 51 via the arc-shaped arm 55 .

[0030] It can be seen from the above description that the arrangement of the arc-shaped arm 55 allows the connecting piece 52 and the operating portion 53 to be closer to the housing 2 when the locking structure 5 is in the locked state, thereby reducing the risk of the locking structure 5 being accidentally unlocked.

[0031] Furthermore, a first reinforcing rib 551 is provided on the arc-shaped arm 55 .

[0032] Furthermore, a second reinforcing rib 521 is provided on the connecting piece 52 .

[0033] Furthermore, a third reinforcing rib 531 is provided on the operating portion 53 .

[0034] It can be seen from the above description that the provision of the first reinforcing rib 551 / the second reinforcing rib 521 / the third reinforcing rib 531 can improve the structural strength of the locking structure 5, thereby reducing the failure risk of the locking structure 5, which is beneficial to extending the service life of the locking structure 5.

[0035] Furthermore, the connecting piece 52 and the operating portion 53 are connected to form a convex structure.

[0036] It can be seen from the above description that when the locking structure 5 is in the locked state, the operating portion 53 can be very close to the housing 2 .

[0037] Furthermore, a middle area of ​​one end of the operating portion 53 away from the connecting piece 52 has an open convex structure 532 , and a protruding direction of the open convex structure 532 is away from the housing 2 .

[0038] It can be seen from the above description that the open convex structure 532 can facilitate personnel to operate the locking structure 5 .

[0039] Furthermore, a concave-shaped shielding rib 22 is provided on the housing 2 , and a avoidance opening 221 is provided on the shielding rib 22 corresponding to the open convex structure 532 .

[0040] It can be seen from the above description that the shielding rib 22 can shield the edge area of ​​the operating portion 53 except the open convex structure 532, thereby reducing to a greater extent the risk of the lock structure 5 being accidentally rotated, resulting in the lock structure 5 being unlocked.

[0041] Furthermore, the locking cylinder 21 is cylindrical.

[0042] It can be seen from the above description that the cylindrical lock post 21 can make the unlocking and locking process of the lock plate 51 smoother.

[0043] A power supply device comprises the above-mentioned junction box structure.
