[0020] The outer wall of the limit column 44 is rotatably connected to the outer wall of the spring plate 43, the outer wall of the spring plate 43 is slidably connected to the outer wall of the limit plate 42, the outer wall of the clamping block 45 is clamped with the inner wall of the shell 2, and the fool-proof component 3 includes a fixed plate 32, and the fixed plate 32 is provided with two groups, and the inner wall of each group of fixed plates 32 is slidably connected to the limit rod 33 through a slide groove 36, and the slide groove 36 is opened in the wall of the fixed plate 32, and the limit rod 33 slides between the push plate 46 and the fixed frame 41 to lock the position of the push plate 46, and the outer walls at both ends of the limit rod 33 are fixedly connected with a top spring 34.

[0021] The end of the top spring 34 away from the limit rod 33 is fixedly connected to the outer wall of the fixing plate 32, and the elastic potential energy is released by the top spring 34, thereby pushing the limit rod 33 to slide between the push plate 46 and the fixing frame 41, and the outer walls at both ends of the limit rod 33 are fixedly connected with connecting plates 35, and the outer wall of the limit rod 33 is slidably connected to the outer wall of the push plate 46, and the outer wall of the limit rod 33 is slidably connected to the outer wall of the fixing frame 41, and the side of the connecting plate 35 away from the limit rod 33 is fixedly connected with the pull plate 31, and the bottom of the fixing plate 32 is fixedly connected to the outer wall of the top of the fixing seat 1.

[0022] Working principle:

[0023] When in use, first press the quick-connect components 4 on both sides of the fixing base 1, then slide the shell 2 onto the fixing base 1, and then release the pressure on the quick-connect components 4 so that the quick-connect components 4 lock the shell 2, and then lock the position of the quick-connect components 4 through the anti-foolproof component 3 to prevent the quick-connect components 4 from being accidentally touched when wiring the circuit breaker, thereby preventing the internal components from being exposed.

[0024] When using the quick-connect assembly 4, it is only necessary to press the push plate 46 on the fixing frame 41, and the push plate 46 pushes the card block 45 to rotate along the fixing column 47. A spring plate 43 is connected between the card block 45 and the limiting plate 42, and the limiting column 44 is used to limit the position of the spring plate 43. Therefore, the card block 45 can squeeze the spring plate 43 during the movement, so that the spring plate 43 accumulates elastic potential energy. After the card block 45 rotates, the top of the card block 45 is away from the shell 2, and the shell 2 can be placed. After the shell 2 is placed, the force on the push plate 46 can be released, and the spring plate 43 can release the elastic potential energy to push the bottom of the card block 45 to move so that the top of the card block 45 can slide into the groove in the shell 2.

[0025] It should be noted that before using the quick-connect assembly 4, the lock of the quick-connect assembly 4 by the anti-foolproof assembly 3 must be released. You only need to pull the pull plate 31 upwards, because the two sides of the pull plate 31 are connected to the limit rod 33 through the connecting plate 35, so that the pull plate 31 can synchronously drive the limit rod 33 to slide out from between the push plate 46 and the fixed frame 41, so as to release the lock on the push plate 46. When the push plate 46 needs to be locked, you only need to release the pulling force on the push plate 46, and release the elastic potential energy through the top spring 34 on the fixed plate 32, so that the top spring 34 can push the limit rod 33 to slide downward along the slide groove 36, thereby sliding back into between the push plate 46 and the fixed frame 41.

[0026] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
