Description

Multi-touch detection safety socket

The invention relates to the technical field of power sockets, especially a multi-touch detection safety socket.

The design of the power socket has a long history, and it usually has a housing, a power circuit is installed in the housing, and at least one set of jacks are pierced on the housing, which is mainly used to allow the plug to be plugged in. Electric appliances provide power.

However, the common traditional sockets in the early days did not have a safety design. If water is accidentally splashed into the socket, it is easy to cause electric shock to the user or short-circuit the power circuit, which will affect the safety of electricity use. Moreover, the sockets in general households and public places are usually set at the lower part of the wall not far from the ground, and the socket power supply is turned on all day long without safety protection, which makes it easy for children to use flat needles, iron wires, tweezers, etc. Electric shock caused by insertion of sharp metal objects, especially if the ground is wet and accidentally inserted indiscriminately, is more life-threatening.

A common relatively simple protective measure is to insert a plastic protective cover with a plug-like structure into the power socket. However, this will cause the user to remove the plastic protective cover every time the power socket is used. The plastic protective cover must be inserted again, which is inconvenient for the user. And the plastic protective cover can still be easily removed by hand. Once the plastic protective cover is removed, the jack of the power socket will still be exposed, and children who like to play and plug in randomly may still have the risk of electric shock.

In addition, there are a variety of safety sockets on the market that can solve the above problems, but the design of these conventional safety sockets is relatively complicated, the assembly of multiple components is time-consuming and labor-intensive, and the practicability and functions are not yet perfect, so further improvements are required. necessary.

In view of this, the main purpose of this creation is to provide a multi-touch detection safety socket, which mainly includes: a power supply housing, a power control switch, and a plurality of detection switches; wherein the power supply housing is provided with at least one socket , there are at least two conductive contact shrapnels inside the socket, and at least two jacks are opened on the upper surface of the socket facing the two conductive contact shrapnels to accommodate plugs of standard plugs; the power control switch is set in the power supply housing, One end is connected to an external power supply, and the other end is electrically connected to the two conductive contact springs to control the power on and off of the two conductive contact springs, and the plurality of detection switches are arranged in the socket, and the interval distribution is arranged on the two sockets. Around the hole, the plurality of detection switches are connected in series one by one to form a safety detection circuit, and finally the two detection switches on both sides are electrically connected to the power control switch, wherein each detection switch has at least one touch terminal to protrude Stretch in this jack that it is close to, for the plug-in of standard plug-in to touch all detection switches to be in conduction, just can make this power control switch start and make these two conductive contact shrapnels provide normal energization.

In a preferred implementation, the plurality of detection switches are eight in total and divided into two groups, and each group has four intervals distributed at the front and rear positions corresponding to the two sides of each jack.

In a preferred implementation, in the safety detection circuit formed, the two detection switches separated on the front or rear sides of each jack are connected by a vertical jumper, and the two detection switches on the outside front and rear The switches are connected by crossing jumpers, and the rear two detection switches on the inner side of the two jacks are connected by short jumpers, and the two front detection switches on the inner side are electrically connected with the power control switch.

In a preferred implementation, the socket is a Chinese standard socket with two eight-shaped sockets and a grounding hole.

In a preferred implementation, the socket is a U.S. socket with two parallel sockets and a grounding hole.

In a preferred implementation, the power supply casing is further wall-plug type, including: a cover, a base, and a socket bracket, the cover has two socket holes and is detachably combined with the base, and is connected with the base An accommodating space is enclosed, the socket bracket is arranged in the accommodating space, and two assembly positions are arranged on it for disposing two of the sockets.

In a preferred implementation, the power supply housing is further in the form of an extension cable, comprising: an upper housing and a lower housing, the upper housing has at least two socket holes and is detachably combined with the lower housing, and is connected to the lower housing The lower casing encloses an accommodating space, and the lower casing is provided with at least two assembly positions for disposing at least two of the sockets.

Compared with the existing conventional structure, the advantage of the multi-touch detection safety socket of this creation is that the plurality of detection switches are connected in series one by one and arranged around the two jacks to form an effective safety detection circuit. When the standard plug-to-plug contact detection switch is in conduction, the power control switch can only be activated so that the two conductive contact shrapnels can provide normal energization. On the contrary, if one circuit is missing and abnormal, the power supply will not be available, which can avoid the risk of electric shock caused by children inserting metal objects on one or both sides, so as to effectively improve the safety of electricity use.
