Description
Technical field
The utility model belongs to Electrical Safety resist technology field, is specifically related to a kind of leakage protecting plug of energy waterproof.
Background technology
Leakage protecting plug is also referred to as residual current protecting plug.When electrical leakage, in electric loop, will inevitably some electric current not to flow back to transformer from live wire through center line, but flow into the earth through electric conductors such as ground wire or human bodies, form a tributary beyond main circuit, be exactly our said electric leakage at ordinary times.When this part electric current, when human body flows into the earth, just cause the people to get an electric shock.The effect of leakage protecting plug is the electrical equipment connect when this plug, during if there is electric leakage, does not also reach before the magnitude of current of injury human body just automatically by dump the protection personal safety at leakage current.
Existing leakage protecting plug, as Chinese utility model patent Granted publication CN2609228, disclose a kind of " safety plug of capable of preventing earth wire charge "; Again for example, Chinese utility model patent Granted publication CN2562439, disclose a kind of " leakage protecting plug ", and the technical characterstic of above-mentioned patent publication us is all that earth leakage protective device is placed in to bayonet cap, makes plug possess creepage protection function.But they all do not have waterproof seal, be not suitable for the place that water or humidity are larger, otherwise frequent outage will occur, terminal appliance can't normally be used.
For above-mentioned existing problems, a kind of leakage protecting plug with water-proof function occurs again in the market, but usually all only limited to front, local waterproof, be useful in the little place of general humidity.When having the larger place of water or humidity to use, for example, in bathroom, not enough and easily make the electronic component of leakage protecting plug inside be short-circuited because of water inlet or lose efficacy due to the measure of waterproof sealing, can lose defencive function equally.
For this reason, the applicant has done actively and effectively to explore, and has finally found the technical scheme addressed the above problem, and has taked to the experiment proved that it is practicable under strict secrecy provision.
Summary of the invention
The purpose of this utility model is the leakage protecting plug that a kind of energy waterproof will be provided; it is protection against the tide, waterproof effectively; thereby greatly improved the safety and reliability of leakage protecting plug when having place that water or humidity are larger to use, made its scope of application wider, longer service life.
The purpose of this utility model reaches like this, a kind of leakage protecting plug of energy waterproof, comprise upper cover, lower cover with pin holes, be arranged on the pin on pin base, be placed in actuating mechanism and circuit board in the containing cavity that upper cover becomes with lower cover institute enclosure, line card, the first lampshade, the second lampshade, reset button key and test button, be characterized in: described upper cover offers groove under the use state with on the contacted end face of lower cover, described lower cover is provided with flange under the use state with on the contacted end face of upper cover, described flange is embedded in described groove and uses sealant sealing between the two, be arranged with pad on described pin, pin inserts in the pin holes of lower cover, and makes pad between described lower cover and described pin base, and described pad is realized the sealing between the pin holes of pin and lower cover by fluid sealant or O type rubber ring, described line card seals with sealing ring at the contact site with upper cover, lower cover, described the first lampshade, the second lampshade and test button be arranged on respectively on described cover and and described upper cover between all adopt the mode structure of ultrasonic bonding for being tightly connected, described reset button key is arranged on described and covers, this reset button key adopt rubber make and by the extruding of actuating mechanism and circuit board and between described upper cover structure for being tightly connected.
In a specific embodiment of the present utility model, described pad is provided with chamfering on the face contacted with pin, and described fluid sealant or O type rubber ring are placed in described chamfering.
In another specific embodiment of the present utility model, described sealing ring is O type rubber ring.
The utility model is due to after adopting said structure, the beneficial effect had: owing to having additional the fit structure of flange and groove between the contact-making surface contacted with lower cover at upper cover and using sealant sealing; Have additional pad on pin, described pad is provided with chamfering on the face contacted with pin, is provided with fluid sealant or O type rubber ring in described chamfering, for the sealing between the pin holes to pin and lower cover; Described upper cover, lower cover are adopting the seal with elastometic washer of O type equally with described line card position; Described first, second lampshade and test button respectively and the mode structure that all adopts ultrasonic bonding between described upper cover for being tightly connected; Described reset button key adopt rubber make and by the extruding of actuating mechanism and circuit board and between described upper cover structure for being tightly connected; thereby realized the comprehensive sealing to leakage protecting plug; greatly improved leakage protecting plug at the safety and reliability that have the larger place of water or humidity to use; make its scope of application wider, longer service life.
