The utility model aims at overcoming the defects of the prior art and providing a waterproof structure of a leakage protector with simple structure and good waterproof performance.
Description
[technical field]
The utility model relates to a kind of waterproof construction of earth leakage protective device.
[background technology]
Under many circumstances; earth leakage protective device is the electrical equipment of outdoor use; waterproof there is very high requirement; the waterproof effect at existing earth leakage protective device wire hole place is difficult to reach requirement, and the earth leakage protective device that needs a kind of good water-proof effect offers outdoor electrical equipment to satisfy the requirement of outdoor electrical equipment to water resistance.
[utility model content]
The utility model purpose is to have overcome the deficiencies in the prior art, provides a kind of simple in structure, the waterproof construction of the earth leakage protective device that water resistance is good.
The utility model is achieved through the following technical solutions:
A kind of waterproof construction of earth leakage protective device; comprise housing 1; it is characterized in that: described housing 1 is provided with wire hole 101; on the described wire hole 101 sealing ring 2 is housed; the described sealing ring 2 outer claw-like clamping rings 3 that are equipped with, described claw-like clamping ring 3 is outer to be set with and to cooperate the locking nut 4 that pushes described forked clamping ring 3 lock sealing circles 2 with described housing 1.
The waterproof construction of aforesaid earth leakage protective device is characterized in that: described locking nut 4 outer ends are inboard to be cancave cambered surface.
The waterproof construction of aforesaid earth leakage protective device is characterized in that: described housing 1 is provided with the protective cover 5 that prevents the stubborn described locking nut 4 of mistake.
The waterproof construction of aforesaid earth leakage protective device is characterized in that: described housing 1 two ends are equipped with wire hole 101.
The waterproof construction of earth leakage protective device according to claim 1 is characterized in that: described sealing ring 2 has the cylindric of flange for outer wall.
Compared with prior art, the utility model has following advantage:
1, the utility model adopts claw-like clamping ring and locking nut to lock sealing ring, and simple in structure, water resistance is good.
2, the utility model housing is provided with protective cover, can prevent effectively that the people from unscrewing locking nut for misoperation, guarantees the water resistance of sealing ring.

[embodiment]
A kind of waterproof construction of earth leakage protective device; comprise housing 1; described housing 1 is provided with wire hole 101; on the described wire hole 101 sealing ring 2 is housed; the described sealing ring 2 outer claw-like clamping rings 3 that are equipped with, described claw-like clamping ring 3 is outer to be set with and to cooperate the locking nut 4 that pushes described forked clamping ring 3 lock sealing circles 2 with described housing 1.
Inboard, described locking nut 4 outer ends is a cancave cambered surface.
Described housing 1 is provided with the protective cover 5 that prevents the stubborn described locking nut 4 of mistake.
Described housing 1 two ends are equipped with wire hole 101.
Described sealing ring 2 has the cylindric of flange for outer wall.
During use, power line is passed from wire hole 101, cover is loaded onto sealing ring 2, claw-like clamping ring 3, locking nut 4 successively, threaded engagement on locking nut 4 and the housing 1 is tightened, the cancave cambered surface effect of in the rundown process because locking nut inboard is inwardly tightened up the claw-like clamping ring and is compressed sealing ring 2, make and form sealing between sealing ring 2 and the power line, form sealing simultaneously between compresses seal 2 and the housing 1.
The utility model adopts claw-like clamping ring and locking nut to lock sealing ring, and simple in structure, water resistance is good.
The utility model housing is provided with protective cover, can prevent effectively that the people from unscrewing locking nut for misoperation, guarantees the water resistance of sealing ring.
