Description
Technical field
The utility model relates to a kind of family expenses and similar applications socket, a kind of specifically band shutter the two poles of the earth, three pole sockets.
Technical background
In order to improve the product safety in utilization, on the family expenses socket, all have shutter.The unlatching of the socket protective door of family expenses and similar applications in the market and closure are that the compression of dependence spring and resilience are ordered about shutter and made reciprocal linear slide basically; because it is bigger with the pressing plate contact-making surface of its support; frictional force each other is also big; often there is shutter not reset and latch inserts the phenomenon have some setbacks, influences the usability of socket.And major part can only prevent that dust from entering and can not prevent effectively that the one pole plug from inserting that serviceability is absolutely unsafe.
The utility model content
The purpose of this utility model is to solve the deficiency that above-mentioned prior art exists, and provides a kind of serviceability and security performance to be with shutter the two poles of the earth, three pole sockets more reliably.
The technical scheme that this socket adopted is: a kind of band shutter the two poles of the earth; three pole sockets; it comprises cover plate; torsion spring is inserted at the two poles of the earth; the two poles of the earth shutter; three extremely insert torsion spring; three utmost point shutters; pressing plate; sleeve component; pedestal; jack is set in the cover plate; have the two poles of the earth fixing hole and the two poles of the earth fixed leg and three utmost point fixing holes and three utmost point fixed legs under the cover plate; the two poles of the earth are inserted torsion spring and three and are extremely inserted torsion spring and be inserted in respectively under the cover plate in the two poles of the earth fixed leg and three utmost point fixed legs; the two poles of the earth are inserted torsion spring and three and are extremely inserted the short pin of torsion spring and insert respectively under the cover plate in the two poles of the earth fixing hole and three utmost point fixing holes; the two poles of the earth shutter and three utmost point shutters overlap the two poles of the earth fixed leg and three utmost point fixed legs under the cover plate respectively; the long pin that the extremely slotting torsion spring of torsion spring and three is inserted at the two poles of the earth stretches out from the two poles of the earth shutter and three utmost point shutters respectively; pressing plate is fixed under the cover plate; the sleeve component pedestal of packing into, cover plate is fixed on the pedestal.
The utility model shutter and cover plate adopt the fit of hole and axle, when latch inserts, shutter is that rotating shaft is rotated the sleeve mouth in the sleeve component is exposed with the fixed leg on the cover plate under the active force of latch, makes latch contact with sleeve in the sleeve component; When latch was extracted, shutter is spinning reduction under the effect of torsion spring.
Prevent that for two pole sockets the one pole latch from inserting, its function is: after the one pole latch inserts jack, with the two poles of the earth shutter contact-making surface be the inclined-plane, the two poles of the earth shutter is subjected to the active force of downward and horizontal both direction respectively like this.Be subjected to the active force of downward direction when the two poles of the earth shutter after, with the pivot point on it is that the axle center is rotated down clockwise, after rotating to certain angle, the boss of the two poles of the earth shutter contacts with the pressing plate of support, stop it again to the lower stress rotation, another Side of pivot point is upturned along jack simultaneously; When being subjected to the active force of horizontal direction, the two poles of the earth shutter is blocked by the block on the pressing plate, and one side of perk blocked by the jack sidewall, and it is mobile so just to stop the two poles of the earth shutter to be rotated in the horizontal direction, reaches the purpose that prevents that the one pole latch from inserting.
Prevent that for three pole sockets the one pole latch from inserting; its function is: the unlatching of three utmost point shutters and closure are to rely on the earth electrode latch in the three-terminal polarized plus plug to drive; and earth electrode is not charged; and be fixed on cover plate and the pressing plate, its freedom of movement is for being that moving back and forth of certain angle spinning reduction carried out in rotating shaft so that fixed leg to be arranged under the cover plate.Do not having under the situation of plug insertion socket; three utmost point shutters are sealed three jack apertures; when the one pole latch inserts firewire jack or zero line jack; because shutter is fixed between cover plate and the pressing plate; be subjected to have displacement space on the force direction; latch can't contact sleeve component, has reached the purpose that prevents that the one pole latch from inserting.
