Abstract
The utility model discloses a kind of Anti-drop plug and sockets, belong to security appliance field.Including push switch, potential device, calutron, the push switch is respectively arranged in plug two sides, and the induction coil is installed on plug and female contact face, and the suction sheet is installed on socket position corresponding with electromagnetic coil installation site on plug.In the case where plug is powered, cannot be pulled out easily by external force；Only when no current in socket, or two sides key is simultaneously when pressing, it could be extracted easily, solving existing plug is easily influenced by external force during use and generates obscission, and children accidentally touching energization plug and the problems such as bring security risk, structure is simple, and safety is available, it is easy to spread, practicability with higher.
Description
Technical field
The utility model provides a kind of Anti-drop plug and socket, belongs to security appliance field.
Background technique
With the rapid development of science and technology, electronic equipment is more and more frequently used by people, the power supply connection one of electronic equipment
As use plug and socket, in real life, the plug on household electrical appliance will carry out plug operation with power outlet, in life
Plug and socket between connection type be mostly to be directly connected to, in use, be easy to receive external force and fall off,
In the group for having children at home, children, which accidentally pull out, to be easy to cause and its serious safety accident, most of for fortune in the prior art
Plug is fastened with mechanical structure, also has and it is fastened with electromagnetic method, it is existing to be carried out tightly with electromagnetic method
Solid structure it is mostly more complicated, higher cost is unfavorable for promoting on a large scale, thus for solve existing issue devise by letter
Single structure provides magnetic force and fastens between plug and socket, realizes strong adsorption force, structure is simple, securely and reliably, easily pushes away
Extensively.
Utility model content
In view of the deficienciess of the prior art, the utility model aim is to provide a kind of Anti-drop plug and socket, pass through
Push switch, Electromalgnetic locking mechanism, suction sheet solve the problems mentioned above in the background art, and the utility model structure is simple,
Strong adsorption force, it is safely and effectively, at low cost, it is easy to spread.
To achieve the goals above, the utility model is to realize by following technical solution: a kind of Anti-drop plug, packet
Include push switch, potential device, calutron, in which: the push switch is by key, contact chip, pressing tablet, reset spring group
At push switch is two, is located at the side of plug, and key lower end and pressing tablet are fixed, and contact chip outer end is respectively and electric
The connection of source conducting wire, contact chip inner end are overlapped on pressing tablet and are separated by key, and it is solid that reset spring one end is connected to plug inside
Fixed, the reset spring other end and pressing tablet lower end are fixed；When on key without external force, contact chip is mutual with pressing tablet always
Contact, when on key by external force, contact chip moves on to key upper end；Potential device is AC transformer, and the transformer is defeated
Enter for plug electric current, output connects calutron；Calutron is at least one electromagnetic induction coil for being mounted on plug mouth.
The further key is isolation material, and contact chip is conductor.
The further electromagnetic induction coil is three.
It is non-conductive layer that the further pressing tablet upper end, which is conductive layer lower end,.
The suction sheet with electromagnetic induction coil cooperation is provided on the further socket panel.
The further suction sheet is iron plate or other magnetisable materials.
The utility model has the beneficial effects that generating magnetic force to plug by electromagnetic induction coil using after voltage transformation
It is fastened in socket, only when two sides switch while pressing or in socket when no current, plug can be unpluged easily；One
Aspect plays the role of power-assisted when being inserted into socket；On the other hand, it ensure that the safety that plug uses, it is therefore prevented that plug receives outer
Power is easy to fall off, and plugs caused electrical shock safety accident.Contact chip, pressing tablet, reset spring Combination Design make
Electromagnet pressing power-off is easy to use.

Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the utility model:
A kind of Anti-drop plug, including push switch, potential device, calutron, the push switch by key 2, connect
Contact 4, pressing tablet 7, reset spring 6 form, and push switch is two, are located at the side of plug, 4 outer end of contact chip difference
It is connected with power lead, 4 inner end of contact chip is overlapped on pressing tablet 7 and is separated by key 2, and the key is this reality of isolation material
Applying a key is plastic material, and contact chip is that conductor the present embodiment contact chip is copper sheet.Pressing tablet upper end is under conductive layer copper sheet
End is non-conductive layer plastics, and reset spring one end is connected to plug inside and fixes, and the other end and 7 lower end plastic layer of pressing tablet are solid
It is fixed；When on key 2 without external force, contact chip 4 contacts with each other with pressing tablet 7 always, when on key by external force, contact
Piece moves on to key upper end；Potential device is AC transformer 9, and the input of transformer 9 is plug electric current, and output connects electromagnetic installing
It sets；Calutron is three electromagnetic induction coils 3 for being mounted on plug mouth, and electromagnetic induction coil is fixed on plug two metal sheets
Two sides, as shown in Figure 1.
The suction sheet 5 cooperated with electromagnetic induction coil 3 is provided on socket panel.The suction sheet be iron plate or other
Magnetisable material such as iron, nickel, cobalt etc., the present embodiment are iron plate.Three iron plates are located at the two sides of socket outlet, position and plug
Electromagnetic induction coil is corresponding.
Family voltage 220V is reduced to 12V (drawn by figure by the transformer 9 being connected in parallel on firewire and zero curve in the present embodiment
The number of turns is not practical the number of turns), it also can according to need and be reduced to other suitable voltages, be powered moment, electric current passes through such as Fig. 1 institute
The electromagnetic induction coil 3 shown generates induced magnetic field, is bonded with the suction sheet on socket, as shown in Figure 4；The plug enable is stable
Combined with socket, when two pressing keys all by external force when or socket in no current when, electromagnetic induction coil is not
Magnetic field is generated, plug can be unpluged easily.
