Abstract

The utility model relates to a ceramic power plug in the manufacturing field of electric appliance, which comprises an upper cover, a lower cover and a plug, wherein the lower cover and the plug are structured integrally; plug built-in jacks are arranged in triangular shape, OO shape or pq shape; one end of the lower cover is provided with a convex post; one end of the upper cover is provided with pressing blocks which are respectively used for pressing an earth wire, a null line and a live line in electric wires, the plug built-in jacks are internally provided with metal parts the ends of which are connected with the electric wires; the ceramic power plug with the structurally integrated plug and the lower cover is simple and durable in structure and easy in manufacturing; the upper cover, the plug and the lower cover are made of ceramic material so as to be heat-resisting particularly, thus the problems of softening and burnout caused by the heating of the electric wires inside the plug can be effectively prevented; the ceramic material with high dielectric constant has better insulation effect than plastic, and can prevent the accident of electric leakage and electric shock.

Description

A kind of ceramic attaching plug

Technical field

The utility model relates to electrical equipment and makes the field, specifically is meant a kind of ceramic attaching plug that electric equipment uses.

Background technology

After policies of reform and opening to the outside world were carried out by China, people's living standard was greatly improved, and household electrical appliance such as television set, refrigerator, electric rice cooker etc. have become indispensable electrical equipment, and popularity rate improves day by day, reaches near saturation condition a few days ago.Past, the electricity charge were higher relatively because income is low, and people just purchase some lower powered household electrical appliance such as fan and so on.Today, income has improved, the improvement of living, people also understand the life that pursuit of enjoyment is high-quality more, therefore a large amount of high-power electric appliances enters ordinary citizen family.Air-conditioning, microwave oven, electromagnetic oven, electric rice cooker, electric frying pan, electric heater, electric water-boiling device etc. all appear in the common family, in these power consumptions high-ranking official, except the air-conditioning caloric value is less, caloric value during other electrical work is very big, and its heat can be delivered to plug and electric wire from electrical equipment itself.

In addition, the high-power electric appliance power consumption increases, and the electric wire overcurrent increases greatly, and the also as easy as rolling off a log heating of electric wire, plug causes blowing circuit, causes large area blackout then, takes place often.Even sometimes also can the breaking out of fire accident, jeopardize the person and property safety.

The easiest above-mentioned place of conducting heat and generating heat that causes is the metalwork among plug, and metalwork is connected part with electric wire.If it is bad that metalwork is connected with electric wire, perhaps using can get rusty for a long time causes area of passage to reduce, and can produce heating, even the phenomenon that sparkles occur.The plug of prior art great majority adopt plastics to add inorganic fillings as shell, and the plug the inside heating occurs and when sparkling, and the plastic casing of plug can deliquescing, even can burn, and occurs fire incident when serious.

In order to solve the thermo-labile problem of plastic plug, people improve this, use plug portion instead ceramic material, and loam cake and lower cover still use plastic products.Though heat-resisting effect increases like this, but still can not thoroughly deal with problems, accident still happens occasionally.

Summary of the invention

In order thoroughly to solve the plug heating deliquescing that prior art exists even to burn problem, the utility model proposes simple in structure, heat-resisting, durable, manufacturing, use, a kind of ceramic attaching plug easy to maintenance.

The technical scheme that the utility model uses is as follows:

A kind of ceramic attaching plug comprises loam cake, lower cover and plug, and loam cake is connected by bolt with lower cover, is provided with jack in the plug, and described lower cover and plug are integral structure; The built-in jack of described plug is a kind of during isosceles triangle, OO font or pq font are arranged; One end of described lower cover is provided with second circular groove, and the centre is provided with down screw hole, and the other end is provided with projection; One end of described loam cake also is provided with upper half-round slot, and the centre is provided with the hole of tightening up a screw, and the other end is provided with briquetting, forms groove between two briquettings; In the built-in jack of described plug metalwork is set, the end of metalwork connects electric wire.

The used ceramic material of the utility model is that high temperature sintering forms more than 1000 degrees centigrade, preferred aluminium oxide ceramics and stabilization zirconium oxide ceramic.

The beneficial effects of the utility model are:

1) plug and lower cover are integral structure, and be simple in structure, durable, easy to manufacture;

2) loam cake, plug and lower cover are ceramic structure, and promptly whole plug is the ceramic material manufacturing, and ceramic material is that high temperature sintering forms more than 1000 degrees centigrade, and is heat-resisting especially, and what can prevent effectively that the electric wire heating causes in the plug feels like jelly, burns problem.

3) ceramic dielectric constant height, promptly insulation effect is more much higher than plastics, can prevent that electric leakage and electric shock accidents from taking place.
