Abstract
The invention discloses a safety protection socket which comprises an insertion component, a pressing connection component, a first clamping linkage component, a second clamping linkage component and a conductive connection component. When a plug is inserted to the insertion component, the plug props against the first clamping linkage component and drives the second clamping linkage component to act, and the plug props against the pressing connection component so as to enable the pressing connection component to shift downward, thus a first conductive contact part of the conductive connection component is contacted with a second conductive contact part mutually to form an electrical connection; and when the plug is pulled out of the insertion connection component, the first clamping linkage component and the second clamping linkage component are far away from the pressing connection component so as to enable the pressing connection component to shift upward, thus the first conductive contact part of the conductive connection component is separated from the second conductive contact part so as to form an open circuit.
Description
Technical field
The invention relates to a kind of design of socket, particularly in the time that one of them conductive insert that inserts foreign matter or plug inserts, be electroless state about a kind of, and the safety protection socket of power supply only just can be provided in the time of the pair of conductive inserted sheet correct insertion simultaneously of plug.
Background technology
Generally speaking, the plant in electrical appliance or workplace at home, all needs to utilize one to be plugged on the jack of socket from the extended wire and plug of equipment, and make power supply via in electric wire access arrangement and produce expection function.In society now, under the situation that people improve year by year for the utilization rate of electrical appliance, the demand of socket also increases day by day, so though at home or the setting of workplace socket be not one of three step, look around and be also not difficult to find their existence.
As shown in Figure 1, it is the schematic diagram that is related to that shows traditional plug and supply socket.Traditional supply socket 100 is made up of a upper shell cover 11 and a lower cover 12, the top surface of upper shell cover 11 is provided with two jacks 111 that can insert for the inserted sheet 131 of plug 13, so that the inserted sheet 131 on plug 13 contacted to the conductive copper sheet 14 in lower cover 12, and the power supply on conductive copper sheet 14 can be transferred in used electric equipment via the inserted sheet of plug 13 131.
But, though traditional socket can provide people to locate easily, but because its jack long term exposure is in outside, provide the live wire of electric current pin end and be equipped with in its hole, not only very easily cause the situation of the impaired of electric power system or electric leakage due to the intrusion of foreign matter, and with general applied supply socket at present, power line is directly connected on two conductive holders in socket, be communicated with accordingly the inserted sheet of the plug inserting, only because of the jack of supply socket, be generally open state, as long as accidentally one of them conductive insert of conducting objects or plug is inserted, just very easily occur to get an electric shock unexpected, especially child or the child of ignorant in family, because the cause of strong curiosity often will have conductive metal sharp shaped material (as pin, awl ... etc.) stretch in the jack of socket and cause the facts of electric shock to occur.
