Description
Technical field
The utility model relates to a kind of plug, especially a kind of leakage protecting plug.
Background technology
Increasingly universal along with industrial production facilities equipment and household electrical appliance, the chance of people and electrical contact gets more and more, and power consumption equipment breaks down and causes the get an electric shock situation of injures and deaths of personnel to happen occasionally.In order to personal safety and device security, earth leakage protective device is widely used as an effective electrical safety technique device, and plays the important and pivotal role.Based on earth leakage protective device principle; protected better to make user; a lot of product is all configured with leakage protecting plug now; when the electric equipment be connected with leakage protecting plug occurs to leak electricity; leakage protecting plug can within a few tens of milliseconds automatic cut-off power; make user from the harm of getting an electric shock, the life security of protection user.
Leakage protecting plug is generally arranged on some electrical equipment used in wet environment, and in place (as swimming pool, shower house, kitchen, toilet etc.) moist especially, because human epidermal resistance reduces, the danger of getting an electric shock and dying increases greatly.But existing leakage protecting plug only comes waterproof, protection against the tide by housing; not enough to the protection of plug self; steam enters plug may damage plug, can not reset or plug can not play earth leakage protective effect after causing plug power-off, affects the normal use of plug.
Summary of the invention
For above-mentioned reasons, the purpose of this utility model is to provide a kind of waterproof, moistureproof leakage protecting plug.
For achieving the above object, the utility model adopts a kind of leakage protecting plug, comprise housing, wire, be arranged on the leakage protection module in housing, two power pins be connected with leakage protection module and grounding pin, described leakage protection module comprises wiring board, electric leakage zero-sequence transformer, ground connection zero-sequence transformer, solenoid, reset button, testing button, contact pressing plate, reed and grounding contact, electric leakage zero-sequence transformer, on ground connection zero-sequence transformer and solenoid connection line plate, reset button and testing button are arranged in the circuit board, contact pressing plate is arranged on reset button lower end, solenoid center is provided with iron core, iron core is connected with locking plate, the locking plate other end is connected in reset button through contact pressing plate, ground wire in wire is connected with grounding contact through ground connection zero-sequence transformer, grounding pin is connected with grounding reed, grounding reed is horizontal below contact pressing plate, the corresponding grounding contact in grounding reed top arranges earthing contact, live wire in wire is connected with reed through electric leakage zero-sequence transformer with zero line, reed is horizontal above contact pressing plate, corresponding two power pins in reed top are provided with moving contact, described housing is wrapped with rubber sleeve, on housing, corresponding reset button and testing button form reset button hole and testing button hole respectively, described reset button is wrapped with the reseting sleeve that rubber is made, reseting sleeve upper end is closely set in reset button hole, testing button is that rubber is made, the upper end of testing button is closely set in testing button hole.
The utility model is set to described rubber sleeve injection mo(u)lding further outside housing.
The utility model is set to described reset button lower end side further and forms locked groove, and the corresponding reset button of locking plate forms lockhole, and reset button is through in lockhole, and the corresponding locking plate of contact pressing plate forms locking plate hole, and locking plate is stuck in locked groove through locking plate hole.
The utility model is set to described contact pressing plate further and extends to form support bar to both sides, and support bar is arranged on the downside of reed.
The beneficial effects of the utility model are at the outer injection moulding last layer rubber sleeve of housing, play the effect of insulative water-proof, also exposed button outside is all superscribed rubber layer or adopt elastomeric material to make, make the gap between button and housing enough little, the object of waterproof can be played, improve the utility model useful life in wet condition.The utility model has power line earth leakage protective and earth-leakage protection simultaneously; there is electric leakage and all power line and earth connection can be disconnected in any line; protection more comprehensively; and electric leakage first disconnects during earth leakage protective; disconnected after ground connection; during reset, earth connection is connected, and designs like this and can prevent electrostatic from remaining, and improves the protective value of the utility model to electrical equipment and personal safety.
