Abstract

These invention publics a kind of ceramic heater (1) and its brand iron for heating. The invention is composed of heating resistor (2), ceramic body that connects to the heating resistor (2) and educes picture (3), hole (4) in the ceramic heater (1), hole conductor coating (5) formed at hole inner side at any rate, electrode welding pattern (6) linking between the ceramic heater (1) and hole conductor coating (5), connecting wire member (7) on the electrode welding pattern (6) at least, metallic material (9) filled between the conductor coating (5) and educed picture (3). Thereby the coupling part of wire guiding member can be more durability to the heating-cooling cycles and has longer life.

Description

technical field [0001] The present invention relates to a ceramic heater and a heating soldering iron using the same, and more particularly to a ceramic heater and a heating soldering iron using the ceramic heater for the following devices: heaters for heating air-fuel ratio detection sensors for automobiles, and heaters for carburetors. Heaters, spark plugs, vaporizers, ignition / carburizers for petroleum furnaces, sealing machines, various industrial machines, heaters for soldering irons, heaters for curling irons, etc. Background technique [0002] Conventionally, as heaters for air-fuel ratio sensors and other automotive heaters, such as Figure 4 (a) shows the cylindrical ceramic heater. This ceramic heater is constituted by, for example, embedding a heating resistor 22 made of a refractory metal such as W, Re, or Mo in a ceramic body 21 mainly composed of alumina, and at the end of the heating resistor 22 Lead member 27 is connected to lead member 27 via electrode pad ...
