[0034] As shown in Figure 5 , Figure 6 and Figure 7 As shown in

[0035] As shown in Figure 6 and Figure 7 As shown in

[0036] As shown in Figure 6 and Figure 7 As shown in

[0037] As shown in Figure 5 As shown in

[0038] As shown in Figure 3 and Figure 4As shown, the upper cover member 100 comprises an upper cover body 101, a plurality of fixing sleeves 102 are embedded in the top of the upper cover body 101, the middle part of the fixing sleeve 102 is fixedly connected with a terminal post 103, the terminal post 103 is electrically connected with the circuit board 300, such a design can conveniently connect the external power line or signal line to the circuit board 300 through the terminal post 103, and realize the electrical connection of the motor starter.

[0039] As shown in Figure 3 and Figure 4 As shown, the middle part of the upper cover body 101 is provided with a positioning sleeve 104, and the circuit board 300 is provided with a corresponding through slot, the positioning sleeve 104 is movably inserted into the through slot, so that the accuracy and stability of the circuit board 300 during installation can be ensured, and the circuit board 300 is prevented from being deviated due to movement or vibration.

[0040] The lower cover body 201 and the upper cover body 101 are provided with a sealing member, which can enhance the sealing property between the lower cover body 201 and the upper cover body 101.

[0041] When the circuit board 300 is installed, the circuit board 300 is placed in the installation space of the lower cover member 200, then the circuit board 300 is pushed upward to make it contact with the locking assembly 204, the bottom of the circuit board 300 will first contact the inclined edge part of the locking block 2042, due to the design of the inclined edge part, when the circuit board 300 continues to move upward, the locking block 2042 will slide inward on the frame 2041, at the same time, the sliding rod 2043 is slid in the support plate 2044 and compresses the spring 2045;

[0042] With the further rising of the circuit board 300, the inclined edge part of the locking block 2042 will gradually pass over the edge of the circuit board 300, when the circuit board 300 reaches the predetermined position, the top of the circuit board 300 will abut against the bottom of the rubber pad 203 of the limiting strip 202, at this time, the elastic potential energy stored in the spring 2045 due to compression starts to release, the release force of the spring 2045 pushes the locking block 2042 to move, so that the bottom of the locking block 2042 tightly abuts against the bottom of the circuit board 300, thereby realizing the locking of the circuit board 300;

[0043] During the locking process, the locking block 2042 is kept in the locking position due to the continuous action of the spring 2045, so as to ensure the stable installation of the circuit board 300, at the same time, the limiting plate 2046 abuts against the support plate 2044, which prevents the locking block 2042 from being completely pulled out of the frame 2041, and further increases the structural stability and reliability of the locking assembly 204.

[0044] It is to be understood that the terms "including", "comprising", or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus.
