Abstract
The utility model relates to an electric iron used in electronic and household appliance maintenance by electricians, in particular to a printed circuit ceramic heating core. A through hole is arranged in the middle of a ceramic bar. The connecting position of a guide line and the ceramic bar is located on the inner side of the through hole and is communicated with a printed circuit. The printed circuit ceramic heating core is simple in structure, convenient to assemble and good in safety of utilization, and ensures uniformity, insulativity and reliability of the heating core in installing.
Description
Technical field
The utility model relates to the electric iron that electronics, electrician and electric appliances service are used, specifically the ceramic heater of electric iron.
Background technology
The period of the ceramic heater that uses in the electric iron is long-standing, particularly often and in a large number uses electric iron on electronics industry, and electric iron is easy to use, safe and good and cheap, for industrial production has played very large effect.In recent years, the printed circuit ceramic heater occurs, compared early stage ceramic heating core performance more superior, early stage ceramic heater adopts resistance wire to be wound on the porcelain tube, and skin carries out sealed insulation with ceramic outer tube, and insulating properties are higher, but the life-span is not long, and packaging effect is not ideal; The printed circuit ceramic heater adopts printed circuit to do heater, by high temperature sintering, printed circuit is wrapped in the environment of vacuum, so insulating properties is higher, the life-span is longer, and dimensional accuracy is better, more and more is subject to liking of user.The exit of the printed circuit of the printing ceramic heater that uses now is the circumferential surface that is positioned at ceramic rod, two wire bonds connect at exit, when being assembled to heat generating core on the electric iron, the heat generating core coated outside weldering and is chewed, weldering is chewed and is connected on the flange that clamp nut is fixed on handle is connected with shell by push pipe, the exit of heat generating core is owing to being positioned at the circumferential surface of ceramic rod, so be difficult to accomplish good insulation, easily in use cause the damage of heat generating core, and the outside dimension of exit is greater than ceramic rod, virtually strengthened the volume of heat generating core, structure to electric iron has certain restriction, so directly affect the structure of electric iron and the security performance of use, increased maintenance cost, and incured loss through delay working time and progress.
Summary of the invention
The purpose of this utility model is to provide a kind of printed circuit ceramic heater in order to overcome above-mentioned the deficiencies in the prior art part, and it is simple in structure, and is easy to assembly, guarantees heat generating core in the uniformity of installing, insulating properties and reliability, and security is good in the use.
Technical solution of the present utility model is on the basis of existing ceramic rod, printed circuit, lead-in wire, and through hole is arranged in the middle of ceramic rod, and the junction of lead-in wire and ceramic rod is positioned at the inboard of through hole, and the junction communicates with printed circuit.
Through hole in the middle of the above-described ceramic rod is circular hole or polygonal hole, and the quantity of through hole is one or more.
Ceramic rod of the present utility model be shaped as circle or polygon.
Operation principle of the present utility model is on the basis of ceramic rod, printed circuit, lead-in wire, and through hole is arranged in the middle of ceramic rod, and the junction of lead-in wire and ceramic rod is positioned at the inboard of through hole, and the junction communicates with printed circuit.Through hole in the middle of the ceramic rod is circular hole or polygonal hole, and the quantity of through hole is one or more.Ceramic rod be shaped as circle or polygon.Because lead-in wire is positioned at the inboard of ceramic rod with the junction of ceramic rod, so when assembling, can not hinder the installation of the element that matches with it, and can improve the insulation degree of heat generating core.When voltage adds to lead-in wire, be connected with printed circuit by the junction, because printed circuit has resistance, can produce heat, make the ceramic rod heating.
The utility model has the advantages that it is simple in structure, easy to assembly, guarantee heat generating core in the uniformity of installing, insulating properties and reliability, security is good in the use.
