Abstract

The invention discloses a power socket and a conductive contact spring. A power plug is inserted into the power socket so that the power plug and the power socket are in contact so as to switch on a power supply. After the power socket is used repeatedly, the conductive contact springs in the power socket are deformed so as to cause poor contact, an increase in contact resistance, heating and short circuit, and even fire hazards. A technical scheme for solving the problems is that the conductive contact springs in the power socket are produced by memory alloy with a one-way shape memory effect; the one-way shape memory alloy has a characteristic of restoring to high temperature phase shape when being heated; by means of the characteristic, when being in poor contact with the power plug and heated because of deformation, the conductive contact springs may automatically restore to original shapes so that a problem is solved that the conductive contact springs are subjected to poor contact because of deformation. Since the conductive contact springs in the power socket have the functions of automatically restoring to original shapes when being heated, the service life of the power socket is greatly prolonged and fire hazards are prevented.

Description

Supply socket and conductive contact shell fragment

Technical field

The present invention relates to supply socket field, can automatic restorable socket and conductive contact shell fragment thereof after particularly relating to the distortion of a kind of conductive contact shell fragment.

Background technology

At present, known plug inserts supply socket and electrical equipment and power supply can be connected, and electrical equipment is then started working, and in actual life, plug and socket are extensively used by people.

But, in actual use procedure, because the shape of plug is different, with plug Reusability on a socket of various shape, just there will be the distortion of plug conductive contact flat spring, cause plug and female contact bad and make the situation that contact resistance increases, cause plug and socket to generate heat, sometimes short circuit is formed, even breaking out of fire.

And also do not have in the market a conductive contact shell fragment can be made to use distortion after can automatic restorable socket, there is no similar product through consulting yet.

Summary of the invention

For the defect of above prior art, the technical problem to be solved in the present invention is: the automatic restorable supply socket of energy after providing a kind of conductive contact shell fragment to generate heat, namely has the socket of self-healing function.

Technical scheme of the present invention is for achieving the above object: the employing of the material of the conductive contact shell fragment in conventional electrical socket is had the memorial alloy making that the electric conductivity of one way shape-memory effect is good.

The one way shape-memory effect of marmem refers to that memorial alloy is out of shape at low temperatures, can return to the shape before distortion after heating, and shape when can not recover low temperature when again cooling.

Heating energy makes memorial alloy revert to the phase transition temperature of temperature value this memorial alloy of the shape before distortion again.

The present invention utilizes this characteristic of marmem to solve the problem on deformation of supply socket conductive contact shell fragment just.After supply socket conductive contact shell fragment selects the memorial alloy with one way shape-memory effect to make, conductive contact shell fragment is just provided with the automatic restorable function of heating.When the conductive contact shell fragment of supply socket and Plug contact bad time, the contact resistance of conductive contact shell fragment and plug increases thereupon, plug and socket is caused to generate heat, when heating temp reaches the phase transition temperature of conductive contact shell fragment, conductive contact shell fragment just utilizes its " memory " shape function and makes its shape automatically restore to reset condition, thus makes plug and conductive contact shell fragment recover good contact.

Another object of the present invention is to provide one and has automatic restorable conductive contact shell fragment.

The phase transition temperature value of memorial alloy can be changed by the proportioning components and Technology for Heating Processing changing memorial alloy.When making conductive contact shell fragment, selecting suitable phase transition temperature memorial alloy, again through the process of corresponding Technology for Heating Processing after being made by machining, the conductive contact shell fragment of various required phase transition temperature value can be made into.

The above supply socket comprises unit supply socket, polynary supply socket, Fixed power-supply socket, mobile power socket etc., and the conductive contact shell fragment of the various shapes be simultaneously made into by memorial alloy is applicable to above various socket.

The beneficial effect of this supply socket is: can prevent supply socket to generate heat because of loose contact the electric pole short circuit caused, prevent from leading to fire, simultaneously because it has the automatic restorable function of heating, so considerably increase the life-span of socket.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the invention will be further described.

In figure: 1 is the pin of plug, 2 is conductive contact shell fragments of socket, and 3 is shells of plug, and 4 is shells of socket.

Embodiment

Below in conjunction with Figure of description, the present invention is described in further detail.

The conductive contact shell fragment of supply socket in accompanying drawing is made by the memory alloy material with one way shape-memory effect.

Accompanying drawing 2 shows plug and is normally connected with the conductive contact shell fragment of supply socket, and face contacts with face, and contact is good.

Accompanying drawing 3 shows socket after Reusability, and the conductive contact shell fragment of distortion and plug form the state of loose contact, and form point and the connection of putting, contact resistance increases thereupon, causes plug and conductive contact shell fragment to generate heat.When heating temp rises to the memorial alloy phase transition temperature of conductive contact shell fragment, the shape of conductive contact shell fragment just because the memory effect of memorial alloy returns to reset condition, thus gets back to the good contact in face and face.
