A first clamping protrusion 331 is provided on the side of the first end plate 33 close to the plug hole 32, and a second clamping protrusion 341 is provided on the side of the second end plate 34 close to the first plug hole 31.

[0024] See also Figure 4 , Figure 5 The protection door assembly 2 includes a first protection door 21 , a second protection door 23 , and a spring 22 mounted between the first protection door 21 and the second protection door 23 .

[0025] Specifically, the first protection door 21 has a first slot 213 at one end and a boss 211 at the other end, with a key 212 on the side wall of the boss 211. The second protection door 23 has a second slot 232 at one end and a receiving hole 231 at the other end.

[0026] The boss 211 is inserted into one end of the spring 22, and the key 212 provided on the side wall of the boss 211 is interference fit with the inner diameter of the spring 22, so that the spring does not fall off during assembly. The other end of the spring 22 is assembled in the accommodating hole 231, which limits the spring 22 and provides space for the compression of the spring 22. The first protection door 21 and the second protection door 23 connected by the spring 22 are assembled between the first end plate 33 and the second end plate 34. The first clamping protrusion 331 is used as a female connector to cooperate with the first clamping groove 213 as a sub-connector, and the second clamping protrusion 341 is used as a female connector to cooperate with the second clamping groove 232 as a sub-connector, so that the first protection door 21 and the second protection door 23 will not pop out under the action of the spring.

[0027] The first protection door 21 and the second protection door 23 are placed in the installation position by squeezing the spring 22, and the spring 22 is released, so that the first protection door 21 and the second protection door 23 can be pressed against the first end plate 33 and the second end plate 34, and the first clamping protrusion 331 is matched with the first clamping groove 213, and the second clamping protrusion 341 is matched with the second clamping groove 232, so as to facilitate assembly and improve assembly stability and safety.
