Technical Field

The invention relates to the technical field of sockets, in particular to an anti-loosening and anti-short-circuit socket.

Background

The socket is used as a power utilization medium frequently used in daily life, and the convenience and safety of use of the socket are particularly critical. However, in the long-term use process, the finding is that in order to prevent the plug from loosening and falling off in the power utilization process, the socket is internally provided with a plugTwo groups of spring leaves which have elasticity and are used for clamping the plug are usually arranged, but along with the longer service time of the spring leaves, the friction loss with the plug is serious, the structure is changed, the clamping effect cannot be realized, the phenomena of looseness and poor contact are easy to occur, the contact resistance of the two groups of spring leaves is increased, heat is deposited, short circuit occurs, and fire can occur in serious cases; in addition, as can be seen from the formula I ═ P/U, when the voltage is constant, when a socket is connected to a high-power electrical appliance, such as an electric furnace, the current of the power transmission line is increased, and the joule law Q ═ I²Rt, it is known that the wire generates heat remarkably, and the wire insulation may be burned, which also causes a fire.

To solve the above problems, we propose a locking short-circuit prevention socket.

Disclosure of Invention

The invention aims to solve the problems in the background art and provides a looseness-proof short-circuit-proof socket.

In order to achieve the purpose, the invention adopts the following technical scheme: the utility model provides a locking short circuit socket that prevents moving, includes socket and plug, the socket includes inlays the dress in the wall body, square casing, the rear side inner wall fixed mounting of casing has two pairs of clamping spring leaf, and two pairs of clamping spring leaf respectively with live wire, zero line electric connection, the front end of casing and seted up the jack on the corresponding position of two pairs of clamping spring leaf, the plug includes the base member and inlays the two inserted sheets of dress in the base member front end, two inserted sheets can insert respectively through the jack and correspond a pair of clamping spring leaf, the front end of casing and seted up two strain holes between two jacks, the iron core is installed to the inner wall in strain hole, two the outer wall of iron core twines jointly the connecting wire one, the connecting wire one is spring-like winding many circles and the same to the spiral direction at the outer wall of two iron cores, is located between two iron cores a connecting wire electric connection has pressure switch, both ends of the first connecting wire are electrically connected with fixed conducting strips;

the rear side inner wall fixedly connected with of casing is criss-cross insulating heat conduction pole, both ends contact with two pairs of tight reeds of clamp respectively about the insulating heat conduction pole, the other one end fixedly connected with memory metal stick of insulating heat conduction pole, the memory metal stick is the bar-shaped structure when just normally, works as when memory metal stick temperature exceedes its abnormal temperature, turns round into the heliciform, and memory metal stick twists reverse 180, the one end fixedly connected with insulator spindle that insulating heat conduction pole was kept away from to the memory metal stick, the equal fixedly connected with in both ends of insulator spindle moves the conducting strip, two it is connected with mains supply through connecting wire two, converter jointly to move the conducting strip, two move the conducting strip and contact with two fixed conducting strips respectively and be connected.

In the anti-loosening and anti-short circuit socket, the insulating heat conducting rod is made of a ceramic material.

In the anti-loosening and anti-short circuit socket, the memory metal rod is made of nickel-titanium memory alloy.

Compared with the prior art, this locking short circuit prevention socket that moves has:

1. when an electric appliance needs to be powered by a plug and a socket, two inserting pieces of the plug are respectively inserted into a corresponding pair of clamping reeds through inserting holes, a pressure switch is pressed to be connected with a trigger closed circuit, a mains supply is converted into direct current through a converter and is connected into a first connecting wire and a second connecting wire, an electromagnet generates a stable magnetic field and generates magnetic attraction force on a permanent magnet, at the moment, the hand of a user stops pressing a base body, after pressing force on the pressure switch is removed, the pressure switch is continuously pressed due to the fact that the electromagnet and the permanent magnet generate the magnetic attraction force, the plug is firmly adsorbed on the socket, and the situation that due to the fact that the clamping reeds are too long in service time, the structure is changed and loosened, contact resistance is increased, and fire;

2. when a high-power electric appliance described in the background art is connected to a socket, and huge heat is generated in a loop, the huge heat is also generated by two pairs of clamping reeds, the clamping reeds conduct the heat to a memory metal rod through an insulating heat conducting rod, the memory metal rod continuously absorbs the heat until the abnormal temperature is reached, the memory metal rod is twisted into a spiral shape, namely the insulating rod is twisted in a rotating manner, when the memory metal rod rotates to the certain degree, the current direction in a trigger closed circuit can be changed, so that the magnetic poles of two electromagnets are changed, and a mutual repulsion force is generated on a permanent magnet, so that a plug can be pushed out of the socket, and the possibility of fire caused by the fact that the heat cannot be dissipated due to continuous electricity utilization is avoided.

In summary, the invention uses the same mechanism to deal with two different modes according to two situations mentioned in the background art, and corresponding solutions are provided no matter the plug is loosened or the power of the electric appliance is too high, so that dangerous situations are avoided.
