Technical Field

The invention relates to the technical field of power connectors, in particular to an overheated self-power-off extension socket.

Background

Along with the improvement of science and technology and the improvement of industrial level, not only rely on the socket of fixing on the wall to realize connecting between consumer and the circuit, can also realize the power supply to consumer through row's socket, the appearance of row's socket has made things convenient for people's life very much.

The existing extension socket reduces resistance by increasing the cross-sectional area of a wire copper core so as to reduce the generation of a heating phenomenon, but when a short circuit or an overload phenomenon occurs in an extension socket circuit, the heat productivity of the circuit is rapidly increased, the internal temperature of the extension socket can be rapidly increased, cables and various electronic components can be easily ignited, so that a fire disaster occurs, although some extension socket shells use flame retardant materials, the continuous high temperature still can cause irreversible damage to plugs and partial components at the connection part, and even can influence the normal use of electric equipment, so that an overheating self-power-off extension socket is provided.

Disclosure of Invention

The invention aims to solve the problems that in the prior art, when the internal temperature of a power strip rapidly rises, the power strip cannot be automatically cut off, electronic components cannot be irreversibly damaged after the temperature reaches a certain value, and electric equipment cannot be normally used.

In order to achieve the purpose, the invention adopts the following technical scheme:

an overheated self-power-off extension socket comprises an extension socket shell, wherein two straight plates are symmetrically arranged on the inner bottom wall of the extension socket shell, an insulating plate is arranged on the two straight plates in a sealing and sliding mode, a telescopic sleeve and two conductive grooves are formed in the insulating plate, electric connecting pieces are symmetrically welded on two sides of the insulating plate and are electrically connected with the corresponding conductive grooves, a round hole and two slots are formed in the top wall of the extension socket shell, the position of the round hole corresponds to that of the telescopic sleeve, the position of each slot corresponds to that of the corresponding conductive groove, a communication port is formed in the middle of the insulating plate, the position of the communication port corresponds to that of the telescopic sleeve, and two conductive rods are further arranged on the inner side wall of the extension socket shell;

the utility model discloses a sealed slide-type multi-plug socket, including insulation board, row's shell, guide way, sealed slide and link to each other with the guide way, rotate on the diapire of insulation board and be provided with two bafflers, and be connected with reset spring between two bafflers, be equipped with the guide way on arranging the inner diapire of inserting the casing, and the bottom of every baffler all links to each other with the guide way is sealed to slide, guide way and two bafflers all are.

Preferably, an evaporation liquid is filled between each barrier plate and the corresponding straight plate, and a non-compressive fluid is filled between the two barrier plates.

Preferably, the included angle between the planes of the two baffle plates is an acute angle, and the range of the acute angle is 15-30 degrees.

Preferably, the bottom end of each barrier plate is provided with a round angle.

Preferably, two placing grooves are symmetrically formed in the extension socket shell, the positions of the two placing grooves correspond to the positions of the corresponding conducting rods respectively, and a transparent plate is hermetically mounted in each placing groove.

The invention has the beneficial effects that:

1. through setting up devices such as baffler board, straight board, insulation board, telescope tube, when circuit overload or short circuit, the heat accessible insulation board that circuit joint department produced transmits in to the evaporant with straight board, and the evaporation of evaporant can promote the baffler and remove to indirect drive telescope tube extension, then ejecting with the plug, the electric connection piece also no longer contacts with the conducting rod simultaneously, borrows this automatic power off who realizes arranging the plug.

2. The non-compressible fluid is extremely difficult to compress, so as long as the evaporation amount of the evaporation liquid reaches a certain value, the telescopic sleeve can overcome certain resistance to change into an extension state, so that the plug is forced to move upwards, and the purpose of breaking and fire prevention is achieved.

3. The bottom of baffler is equipped with the fillet, can make baffler bottom more mellow and full through setting up the fillet, guarantees that it can be in the same direction as smooth removal on the guide way, and simultaneously, the fillet design can make the leakproofness between baffler and the guide way better, avoids two kinds of different liquid to take place to mix.

4. After the plug is inserted, the contact area between the straight plate and the evaporating liquid is increased by the movement of the blocking plate, and the evaporating liquid has larger specific heat capacity, so that the plug can absorb partial heat and reduce the working temperature of the extension socket.

5. This device accessible standing groove in the temperature sensing color change material judge arrange insert and internal circuit's operating temperature whether be higher than safe temperature, if the colour of temperature sensing color change material changes, people can in time discover, then extract the plug, seek the reason to components and parts in the circuit receive irreversible harm.

In conclusion, the invention can reduce the working temperature of the extension socket when in use, and can automatically eject the plug when the circuit is overloaded or short-circuited, thereby achieving the purpose of overheating and self-power-off and avoiding fire caused by overhigh temperature of the extension socket.
