Abstract

A safety power socket comprises a socket and conductive parts arranged in the socket, wherein the upper end surface of the socket is provided with a plurality of groups of plug jacks and an upper cover; the upper cover is provided with a plurality of groups of square holes for plug pins going through; the square holes are positioned right above the plug jacks; the two sides of the internal surface of each square hole are respectively provided with a chute; a dust-proof cover is arranged between the two chutes at the two sides; the upper end surface of the dust-proof cover is provided with a push plate in a protruding manner, and the lower end surface thereof is provided with a spring seat; the lower end surface of the upper cover is provided with a bulgy rod corresponding to the spring seat in a protruding manner; and a spring is arranged between the spring seat and the bulgy rod in a penetrating manner. When the plug is not inserted in the jack of the socket, the dust-proof cover on the upper cover covers the jack under the effect of spring force, thus being capable of preventing foreign matters from entering the jack, avoiding the accident of electric shock, and simultaneously being capable of preventing dust, therefore, the service lives of the socket and electric equipment are prolonged.

Description

A kind of safety power source plug socket

(1) technical field

The utility model relates to a kind of supply socket, relates in particular to a kind ofly can prevent to get an electric shock and prevent that dust from entering the supply socket of jack.

(2) background technology

In the middle of our life and production, in order to provide source current to power consumption equipment, generally use single-phase and three-phase socket, the connection and the disengagement of general socket and plug, make various electric equipments switch on or off power supply, being a kind of electric elements that very generally use, almost is that various electric equipments are requisite.But at present this socket that uses has many shortcomings, so that often has accident to take place, and this is that then electric equipment is cut off the electricity supply because during electricity consumption, we enter power consumption equipment with in the plug insertion socket hole with guide current, after using up, plug are extracted in socket aperture.The shortcoming of this supply socket of generally using is conspicuous: after the first, plug is extracted, it is charged that jack remains, under the more situation of laboratory or the more socket of electric equipment, employed lead or metal device are strayed into also can cause in the socket aperture and get an electric shock or equipment breakdown.Especially child is ignorant of electricity knowledge, might touch the electric-conductor in the socket aperture, causes electric shock accidents.The second, in we lived and produce, some operation had a large amount of dusts, for example, the production process of cement plant, asphalt felt-making factories etc. neutralizes our each family in the cleaning room, perhaps supply socket not cleaning for a long time, extraneous dust is invaded in the jack of supply socket easily, and is deposited on the contact of jack, thereby influence the conductivity between the contact, increase resistance, make the contact heating, consume a large amount of electric energy simultaneously, even cause short circuit, generation equipment or life accident.

(3) summary of the invention

Have above-mentioned deficiency in the prior art in order to overcome, the utility model provides a kind of generation that can prevent to touch the electric-conductor in the socket and cause electric shock accidents, can also prevent that dust from falling into the safety power source plug socket of the effect of socket simultaneously.

The technical scheme in the invention for solving the technical problem is: a kind of safety power source plug socket, comprise socket and be installed in the interior conductive pieces of socket, the upper surface of described socket is provided with several groups of plug-sockets, described socket upper surface is provided with a loam cake, cover on described and be provided with several groups and can hold the square hole that the plug latch passes through, described square hole be positioned at described plug-socket directly over, each square hole inner face both sides is provided with chute, sliding pivot one dust cap between the chute of described both sides, convex with a push pedal on the upper surface of described dust cap, the lower surface of described dust cap is provided with a spring base, the lower surface of described loam cake convexes with and the corresponding prominent bar of described spring base, and places a spring between described spring base and described prominent bar.

As further improvement of the utility model, the both side edges of described socket respectively is equipped with outstanding slide rail, and the both side edges of described loam cake is provided with and the corresponding draw-in groove of described slide rail, and described loam cake is fixed on the slide rail of described socket by draw-in groove.

Further improve as of the present utility model, described push pedal is positioned at the right-hand member of the upper surface of described dust cap, and described spring base is positioned at the middle part of left end of the lower surface of described dust cap, and described prominent bar is positioned at the left side of described spring base.

Described safety power source plug socket can be several groups two spring hole scokets, also can be several groups of Three-hole sockets, can also be the combining of two spring hole scokets and Three-hole socket, and offers corresponding square hole as long as cover on described, is provided with dust cap at the square hole place and device gets final product.

The utility model in use, before plug did not also insert socket, described dust cap covered the square hole that covers on directly over the jack under the effect of spring force.When user's desire is inserted the utility model with plug, the chute slippage that can borrow the push pedal on the dust cap firmly dust cap to be covered on described, thus expose receptacle sockets, in the jack with plug insertion socket, thereby connect power consumption equipment.When not needing to use, pull the plug out of the socket, dust cap restores to the original state under the effect of spring force, and the square hole that covers on directly over the jack is covered.

The beneficial effects of the utility model are: 1. when plug does not insert jack on the socket, on the dust cap that covers jack is covered, can prevent that foreign matter from entering in the jack, thereby prevent the generation of electric shock accidents.2. can prevent dust,, can seal jack, avoid dust to enter, thereby avoid the dust incrustation of contact, make power consumption equipment often be in the dinner state, so just increase the useful life of socket and power consumption equipment when with after not using.3. corresponding dust cap of each group jack and device thereof on the described socket can be organized jack to each like this and carry out different control, and be easy to use, safe and reliable.
