For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] like Figure 1-6 As shown, the leakage-proof electrical housing proposed by the utility model comprises a housing 1 , bolt holes 11 opened at four corners of the housing 1 , and bolts 3 connecting two housings 1 through the bolt holes 11 .

[0032] It includes an anti-leakage component 2, the number of which is the same as the number of bolt holes 11, and each anti-leakage component 2 fills the corresponding bolt hole 11. The anti-leakage component 2 includes an anti-leakage insulating plug 21 filled in the bolt hole 11 for blocking the bolt 3, an anti-slip inner edge ring 22 fixedly connected to the opening of the bolt hole 11 to increase the seal and limit the anti-leakage insulating plug 21 in the bolt hole 11, an insulating top cap 23 fixed to the top of the anti-leakage insulating plug 21, and a T-shaped lifting shaft 24 movably sleeved with the insulating top cap 23 and fixedly connected at the bottom inner wall of the anti-leakage insulating plug 21. Specifically:

[0033] refer to Figure 6, the anti-leakage insulation plug 21 is made of insulating rubber material, which also has a certain elastic force. The anti-leakage insulation plug 21 is composed of an outer edge portion 211, a flat top portion 212, and a V-shaped expansion portion 213 connecting the outer edge portion 211 and the flat top portion 212, forming an expansion structure. The advantage of the expansion is that the bottom end of the V-shaped expansion portion 213 can be tightly attached to the inner wall of the bolt hole 11, and cooperate with the anti-slip inner edge ring 22 to form a limit to prevent the anti-leakage insulation plug 21 from slipping out of the bolt hole 11. The outer wall of the outer edge portion 211 and the inner wall of the anti-slip inner edge ring 22 are inclined surfaces that can fit together to form a limit.

[0034] In this embodiment, the first connecting bar 4 is included to connect the various leakage prevention components 2 into an integral structure to facilitate overall operation and prevent loss. The two ends of the first connecting bar 4 are fixedly connected to the insulating top caps 23 at corresponding positions.

[0035] In this embodiment, a second connecting bar 5 is included for simultaneously driving two T-shaped lifting shafts 24 to move vertically, and both ends of the second connecting bar 5 are respectively fixedly connected to the T-shaped lifting shafts 24 at corresponding positions, and a pressing plate 41 is fixedly connected to the first connecting bar 4 on which the second connecting bar 5 is installed, so that the stability of the anti-leakage component 2 can be maintained by the pressing plate 41 when the second connecting bar 5 is lifted.

[0036] The working principle of this embodiment is: in order to prevent the current from being conducted out through the bolt 3 when the electrical components inside the housing leak, the anti-leakage insulating plug 21 can be filled into the bolt hole 11 to block the bolt 3. Figure 6 The bottom end of the anti-leakage insulating plug 21 expands outward and can be closely attached to the inner wall of the bolt hole 11, and refer to Figure 3 The anti-slip inner edge ring 22 in the bolt hole 11 can prevent the anti-leakage insulating plug 21 from slipping out of the bolt hole 11 because the anti-slip inner edge ring 22 blocks the upper side.

[0037] In this embodiment, when the leakage-proof insulating plug 21 is installed into the bolt hole 11, the T-shaped lifting shaft 24 can be lifted upward first, and the bottom end of the T-shaped lifting shaft 24 drives the bottom of the leakage-proof insulating plug 21, that is, Figure 6 The flat top 212 in the middle moves upward, and the flat top 212 pulls the V-shaped outward expansion part 213 to deform inwardly as shown by the arrow in the figure, thereby reducing the outward expansion diameter of the bottom end of the leakage-proof insulating plug 21, so that it can smoothly enter the bolt hole 11 through the middle hole of the anti-slip inner edge ring 22. After the leakage-proof insulating plug 21 is installed, the T-shaped lifting shaft 24 is pressed back, and the deformation recovery ability of the leakage-proof insulating plug 21 restores it to its original state. The outward expansion bottom of the leakage-proof insulating plug 21 is close to the inner wall of the bolt hole 11 and is blocked by the anti-slip inner edge ring 22 and will not fall out of the bolt hole 11;

[0038] In addition, when pulling the T-shaped lifting shaft 24 upward, one hand can press the pressing piece 41 and the other hand can lift the second connecting bar 5 upward to simultaneously drive the two T-shaped lifting shafts 24 to move upward at the same time, thereby simplifying the operation process.

[0039] In summary, by filling the anti-leakage insulating plug 21 in the bolt hole 11, the bolt 3 can be isolated from the outside of the shell, thereby achieving an anti-leakage function; the anti-leakage insulating plug 21 with a certain elastic force composed of the outer edge portion 211, the flat top portion 212 and the V-shaped outer expansion portion 213, combined with the anti-slip inner edge ring 22, can form mutual limitation to increase the stability of the anti-leakage insulating plug 21 in the bolt hole 11; by pulling the T-shaped lifting shaft 24, the anti-leakage insulating plug 21 is deformed and concave, which facilitates the loading and removal of the anti-leakage insulating plug 21 in the bolt hole 11; the various anti-leakage components 2 can be connected to each other as a whole through the first connecting bar 4, which is convenient for overall operation and prevents loss; and multiple T-shaped lifting shafts 24 can be pulled at the same time through the second connecting bar 5 to improve operating efficiency.

[0040] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
