Abstract

The utility model discloses a safe socket. The safe socket comprises a first dry reed pipe and a second dry reed pipe, wherein the first dry reed pipe and the second dry reed pipe are both provided with solenoid coils matched with the first dry reed pipe and the second dry reed pipe, the first dry reed pipe is respectively connected in series with a zero wire and a socket leg I, the second dry reed pipe is respectively connected in series with a live wire and the socket leg I, the first dry reed pipe is connected in parallel with the second dry reed pipe and is successively connected in series with a current limiting resistor, a diode and a switch so as to form a loop. The safe socket provided by the utility model utilizes the earthing leg of a three-core plug to control a switch in the circuit, each hole of the socket which is extracted from the plug can not generate electricity, and the security of children is fully guaranteed.

Description

Safety socket

Technical field

The utility model belongs to the daily living article field, is specifically related to a kind of safety socket.

Background technology

Supply socket is the most frequently used with the workplace at home device.But their existence is a kind of greatest threat to children's safety.Therefore, people are devoted to address this problem always.At present, there are several series products on the market.One class is to adopt the passive type protection socket of air switch or Leakage Protective Rule, and its shortcoming just can be moved after being to only have human body to contact with it to some extent, also is not safety so in fact; One class is the active protection socket that installs emergency exit or socket cover additional, and its shortcoming is this curiosity that more can excite children of covering, and they can expect that fully way takes away socket cover or destroy emergency exit at a glance actually, and such result well imagines; Also having a class is exactly the protection socket of plug and socket mix proportion electromagnetic switch, and its shortcoming is that this mode is must plug supporting with socket, universal difficult.

The utility model content

Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, a kind of safety socket is provided, with the switch in the grounding leg control circuit of three-prong plug, plug one is extracted in each hole of socket not charged, has fully guaranteed children's safety.

The technical scheme that the utility model adopts is: a kind of safety socket, comprise the first tongue tube and the second tongue tube, be equipped with the solenoid that matches on the first tongue tube and the second tongue tube, described the first tongue tube is connected with zero line, socket one pin respectively, described the second tongue tube is connected with live wire, socket one pin respectively, the first tongue tube and the second tongue tube are in parallel, then connect with current-limiting resistance, diode, switch successively, form the loop.

The beneficial effects of the utility model are: with the switch in the grounding leg control circuit of three-prong plug, plug insertion socket, socket just can work.When taking off plug, switch resets, and cuts off the power supply on the contact in the socket, and is not charged in each hole of socket, guaranteed children's safety.

Description of drawings

Fig. 1 is the utility model structural representation.

Embodiment

Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.

As shown in Figure 1, a kind of safety socket, comprise the first tongue tube and the second tongue tube, be equipped with the solenoid that matches on the first tongue tube and the second tongue tube, described the first tongue tube is connected with zero line, socket one pin respectively, and described the second tongue tube is connected with live wire, socket one pin respectively, and the first tongue tube and the second tongue tube are in parallel, then connect with current-limiting resistance, diode, switch successively, form the loop.

These component sizes that the utility model needs are little, these elements can be made an assembly and be installed in the socket.Its operation principle is: with the switch in the grounding leg control circuit of three-prong plug, plug insertion socket, socket just can work.When taking off plug, switch resets, and cuts off the power supply on the contact in the socket, and is not charged in each hole of socket, guaranteed children's safety.

Claims

1. safety socket, it is characterized in that: comprise the first tongue tube and the second tongue tube, be equipped with the solenoid that matches on the first tongue tube and the second tongue tube, described the first tongue tube is connected with zero line, socket one pin respectively, described the second tongue tube is connected with live wire, socket one pin respectively, the first tongue tube and the second tongue tube are in parallel, then connect with current-limiting resistance, diode, switch successively, form the loop.
