Abstract

The utility model relates to a safety power supply socket, belonging to the technical field of electrical apparatus elements. The structure is that a spring piece is fixed on the spring sheet of a socket. The spring piece is connected and is fixed in an insulation mode with a switch on a power cord. In addition, the switch is movably connected with the spring piece. The utility model has the advantages that the spring sheet on the socket is not arranged with electricity at ordinary time. Only if the insertion sheet of a plug is inserted in a proper position, a power supply can be conducted and communicated. Thus, a safety problem for the electricity utilization of the socket is thoroughly solved.

Description

Safety power source plug socket

The utility model belongs to the electric elements technical field, relates to a kind of improvement of supply socket.

At present, all to be lead be connected with spring leaf in the shell in general supply socket, have jack on the shell, the socket that has is considered from security standpoint, be provided with spring stop piece on jack, but all there is a problem in these two kinds of sockets, is exactly that inserted sheet on the plug contacts with the spring leaf of socket and when also not being inserted into, inserted sheet is promptly charged, and inserted sheet will bring safety problem to the user like this.

The purpose of this utility model provides a kind of plug and is only inserting the safety power source plug socket that just can switch on after supply socket puts in place.

Technical solutions of the utility model are as follows:

Be fixed with a shell fragment in the spring leaf of socket bottom, the switch insulation on shell fragment and the power line is connected and fixed, and switch can with the shell fragment interlock.

The utility model has the advantages that: the spring leaf on the socket is not when time spent or plug slice contact, and spring leaf is all not charged, and only after inserted sheet was inserted into, power supply was just understood conducting, like this with regard to the thorough Electrical Safety problem that has solved socket.

Fig. 1 is the circuit diagram of safety power source plug socket;

Fig. 2 is spring leaf and the switch junctions composition on the safety power source plug socket.

Wherein: the 1st, shell fragment, the 2nd, switch, the 3rd, power line, the 4th, spring leaf, the 5th, jack housing, the 6th, plug slice, R are that resistance, D are light-emitting diodes, shell fragment 1 can be arranged in the zero line jack of socket, live wire be provided with can with the switch 2 of shell fragment 1 insulation interlock, when plug slice 6 inserts the socket endoporus, inserted sheet 6 contacts conducting with the spring leaf 4 of socket on the one hand, oppresses shell fragment 1 on the one hand and drives switch 2 closures.Socket and plug all are in charged conducting state, and after plug slice 6 was extracted the spring leaf 4 of socket out, shell fragment 1 resetted, and switch 2 also disconnects thereupon, and the spring leaf 4 of socket is in non-electriferous state.

Claims

1, a kind of safety power source plug socket, form by spring leaf 4 and jack housing 5, it is characterized in that: be fixed with a shell fragment (1) in the spring leaf (4) of socket bottom, shell fragment (1) is connected and fixed with switch (2) insulation on the power line, and switch (2) can with shell fragment (1) interlock.
