Drawings

Fig. 1 is a schematic structural diagram of a socket for suppressing use of a high-power electrical appliance according to an embodiment of the present invention;

description of reference numerals:

1. a socket body; 2. a power line; 3. accommodating grooves; 4. a self-healing fuse; 5. a protective cover.

Detailed Description

In order to explain the technical content, the objects and the effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.

The utility model discloses the most crucial design lies in: when the power of the used electric appliance is larger, the current is blocked, so that the use of the high-power electric appliance is forbidden, and when the power of the used electric appliance is smaller, the use can be automatically recovered.

The utility model provides a socket that electric appliance used is used to containment high power, include the socket ontology who is connected with the power cord, the holding tank has been seted up on socket ontology's surface, be equipped with two fixed orificess of two pins of fixed self-resuming fuse in the holding tank, two fixed orificess establish ties on the power cord, it has the visor that seals the holding tank still to articulate on the side of holding tank.

Through network inquiry, a self-recovery fuse with a rated voltage of 240V allows passing currents of: various models such as 0.1A, 0.2A, 0.5A, 1A and 2A are available. And the electric appliances that the student can use are: desk lamps, mobile phone or flat panel chargers, small fan lamps, and the like. Through calculation, the maximum power does not exceed 1A when the electric hair drier is used, and the power of the electric hair drier and the electric heater is generally more than 4A. Fuses of three types of 0.5A, 1A and 2A can be bought through Tanbao and inserted into two fixing holes of the accommodating groove respectively for replacement, and the most suitable type under different scenes is determined.

The working principle of the self-recovery fuse is as follows: self-resuming fuse utilizes positive temperature coefficient's resistive material absolutely, when using high power to use electrical apparatus, the electric current ratio in the circuit is great, because this fuse is direct series connection to the circuit in, the sharp rising resistance of temperature also follows the grow, so the voltage that this fuse branch arrived also follows the increase, lead to the high power to use the diminishing at electrical apparatus both ends, the electric current in the circuit also diminishes, so can not normally work with electrical apparatus, play the effect that the containment used high-power electrical apparatus.

Further, in the above socket for suppressing the use of the high power electrical appliance, the self-recovery fuse is a self-recovery fuse allowing a current of 2A or less to pass. The use of the 2A self-healing fuse can better meet the requirements.

Furthermore, in the socket for restraining the use of the high-power electric appliance, the side face of the socket body is provided with a heat dissipation groove, and the heat dissipation groove is covered with a heat conduction silica gel sheet in an attached mode. The existence of heat conduction silica gel piece not only can effectively derive the heat, still can effectively keep apart socket ontology inner structure, avoids electric leakage to take place and debris get into socket ontology.

Furthermore, in the socket for restraining the use of the high-power electric appliance, the side surface of the socket body is provided with the USB interface. The side that corresponds through the socket body broadside is equipped with two USB interfaces, can satisfy the needs of most occasions to the USB interface, and the suitability is strong.

The utility model discloses a socket that electric appliance used is used to containment high power can be used to in the students' dormitory, has following advantage: when a high-power electric appliance is connected, the socket is directly powered off, other circuits in a dormitory are normal, and the socket is recovered to be normal when the high-power electric appliance is pulled down. The socket can effectively prevent students in a residence from using high-power electric appliances, so that the students can safely use electricity, and the workload of a student management teacher is effectively relieved; the design of the protective cover is convenient for replacing and protecting the self-recovery fuse.
