[0017] Please refer to Figures 1-3 , the present utility model provides a technical solution for a leakage protector encapsulation housing structure:

[0018] As shown in Figures 1-3 the figure, it includes a lower encapsulation housing 1 and an upper encapsulation housing 2. The top end of the lower encapsulation housing 1 is fitted and connected with the upper encapsulation housing 2. A sealing component is provided at the fitting connection between the top end of the lower encapsulation housing 1 and the upper encapsulation housing 2. A leakage protection controller 6 is fixedly installed inside the lower encapsulation housing 1, and a protective cover 7 is provided on the top of the leakage protection controller 6.

[0019] Specifically, the leakage protection controller 6 inside the encapsulation housing is further protected by the protective cover 7. Through the setting of the sealing component, the sealing performance at the connection between the lower encapsulation housing 1 and the upper encapsulation housing 2 is increased.

[0020] As shown in Figure 1 、 Figure 2 and Figure 3 the figure, a plurality of threaded holes 5 are equidistantly opened on both sides of the top end of the lower encapsulation housing 1. A plurality of locking bolts 3 are threadedly connected to both sides of the top end of the upper encapsulation housing 2. The plurality of locking bolts 3 are threadedly connected to the corresponding threaded holes 5.

[0021] Specifically, by threadedly fixing the locking bolts 3 with the threaded holes 5, it is convenient to fix the lower encapsulation housing 1 and the upper encapsulation housing 2.

[0022] A plurality of terminal blocks 4 are equidistantly fixed on the top of the upper encapsulation housing 2. Specifically, through the setting of the terminal blocks 4, it is convenient to connect the wires of the leakage protector.

[0023] On both sides inside the upper encapsulation housing 2, sleeves 9 are fixedly provided. Inside the two sleeves 9, sleeve posts 10 are sleeved and connected. The bottom ends of the two sleeve posts 10 are fixedly connected to both sides of the top end of the protective cover 7. A first compression spring 8 is fixedly installed inside the sleeve 9, and one end of the first compression spring 8 is fixedly connected to the top end of the sleeve post 10.

[0024] Specifically, the first compression spring 8 squeezes the sleeve post 10 to move downward. By the downward movement of the sleeve post 10, the protective cover 7 is pushed to move downward, so that the bottom end of the protective cover 7 closely fits the inner wall of the lower encapsulation housing 1.

[0025] A sealing frame 11 is fixedly provided at the bottom of the inner wall of the upper encapsulation housing 2. A plurality of convex blocks 14 are equidistantly provided on both sides of the outer wall of the sealing frame 11.

A second compression spring 13 is fixedly installed inside each of the plurality of round holes 12, and one end of the second compression spring 13 is fixedly connected to one end of the corresponding convex block 14.

[0027] Specifically, the second compression spring 13 compresses the convex block 14 to be nested with the arc-shaped groove 15, which facilitates fixing the sealing frame 11 at the gap at the fitting position of the lower packaging shell 1 and the upper packaging shell 2, improving the sealing effect.

[0028] Working principle: For a leakage protector packaging shell structure of the present utility model, when using this leakage protector packaging shell structure, first, the leakage protection controller 6 is fixedly installed inside the lower packaging shell 1. Then, the upper packaging shell 2 is fitted with the lower packaging shell 1. When the upper packaging shell 2 is fitted with the lower packaging shell 1, at this time, the protective cover 7 covers the leakage protection controller 6, and the first compression spring 8 installed inside the sleeve 9 compresses the sleeve column 10 to move downward, so that the bottom of the protective cover 7 is in close contact with the surface of the lower packaging shell 1. At the same time, the sealing frame 11 at the bottom of the upper packaging shell 2 seals the gap between the lower packaging shell 1 and the upper packaging shell 2, improving the sealing performance of the connection. Then, the locking bolt 3 is manually rotated and threadedly fixed with the threaded hole 5 to complete the assembly between the lower packaging shell 1 and the upper packaging shell 2.
