Abstract

The utility model discloses a safety socket which comprises a jack, a wiring hole and a conductive copperplate. The socket is divided into a wiring chamber (1) and three functional chambers (2, 3, 4). A plug passes through a rubber valve cap (8) to contact the conductive copperplate (9), and a button (10) is arranged below the conductive copperplate (9). The button (10) is provided with a rubber valve through each chamber. The safety socket has the characteristics of electric shock prevention, creepage prevention, ionic discharge prevention, dust prevention, multi-plug mutual breakdown interference prevention, water prevention, breakdown prevention, contact arc spark reduction, the conductive independent switching effect of a socket hole, low cost of a valve, etc. The safety socket is suitable for being used in an unfavorable environment in which dampness is high, temperature fluctuates within a certain range, etc.

Description

Safety socket

The utility model relates to a kind of socket mechanism.

Guarantee that it is the important topic of socket research that socket secure uses always, touched electric shock for preventing the contact on the socket by the people, many methods are to adopt plug to insert back rotation one angle can touch conductive contact blade, but this method dust protection not.Chinese patent 92240658 " socket " with safety device, solved socket dustproof problem, be characterized in upper surface at Socket casing, be provided with a motion block that has pin holes equally, this motion block hole and housing can stagger at ordinary times and socket aperture is closed, but the motion block pin holes overlaps the location during use, does not use pin holes to be closed and does not expose.This method is safer, but not direct, and two actions will be arranged during use, and is also non-watertight.

The purpose of this utility model designs the electrical socket of a kind of protection against electric shock, dustproof, waterproof.

The utility model contains jack with socket, wiring hole, conductive copper plate, socket is divided into wiring chamber (1) and three functional compartments (2,3,4), on external chamber (2): a rubber valve gap (8) is arranged on the jack, there is electricity to lead copper sheet (9) under the rubber valve gap (8), conductive copper sheet (9) is fixed on the dividing plate (5) by screw (11), there is a button (10) conductive copper sheet (9) below, button (14) is a long column, its upper semisection conduction, the lower semisection insulation is non-conductive, one plug insertion (21) is arranged on the conductive copper sheet, button (10) is by having a rubber every dish (13) on the two Room mouths, button is spring (14) by (10) below, and spring (14) below has a spring (16) again for contact guide card (15), contact guide card (15) below, three Room mouths have a rubber shell fragment (19) under the contact conducting strip (15), lead inserts conductive copper plate (17) by wiring hole in the wiring chamber, conductive plate (18) is connected to the conductive copper sheet (9) of a Room from four Room, also has a unidirectional valve (20) on the dividing plate of three Room and wiring chamber.

The utlity model has protection against electric shock, anticreep, anti-ionic discharge, anti-dust, prevent that multitap punctures interference, waterproof, anti-breakdown, the electric lonely spark of reduction contact mutually, socket aperture conducts electricity the effect of independent break-make, guide card friction enhanced effect in plug and the socket aperture, characteristics such as the valve cost is low, can be applicable in the adverse environments such as humidity is excessive, temperature fluctuates within the specific limits and use, and safety, can save the energy loss that causes by common socket and eliminate its intrinsic unfavorable factor, simultaneously can be applied to plug by reinforced design with high power load.

Accompanying drawing 1 is the utility model front view;

Accompanying drawing 2 is not with the electric conductor front view for the utility model;

Accompanying drawing 3 is the utility model end view;

Accompanying drawing 4 is not with the electric conductor end view for the utility model;

Accompanying drawing 5 is the utility model conductive copper sheet schematic diagram;

The utility model is described in further detail below in conjunction with the course of work of accompanying drawing embodiment

The plug bipod inserts the dustproof valve of socket, button (10) moves down, contact guide card (15) is pushed rubber valve open, the right and left contact conductive plate (17), (18), spring (14,16) is compressed, because the frictional force of plug and conductive copper sheet (10) patchhole is greater than the elastic force of spring (14,16), plug inserts the back electricity that puts in place from conductive plate (18), inserts on the conductive copper sheet (9) to conductive plate (14) through contact guide card (11) to reach expectation function.And do not insert the socket aperture of plug, and button (11) is not depressed, and the conductive copper sheet no power can effectively prevent other jack touching electric leakage.
