Abstract
The utility model discloses an improved lead structure of a ceramic heating bar, relates to a ceramic heater, in particular relates to an improved lead structure and belongs to the H05B3 category in IPC (Intellectual Property Classification). The ceramic heating bar consists of a ceramic cylinder core and a cylindrical ceramic layer, the cylindrical ceramic layer is formed by curled ceramic sheets tightly sleeved outside the ceramic cylinder core, a resistance heating circuit is printed on the inner side wall of the cylindrical ceramic layer, two distal ends of the resistance heating circuit respectively pass through two small holes of the inner side wall and are connected with two rectangular electrode pads of an outer side wall, and leads are respectively welded on the electrode pads. The improved lead structure, disclosed by the utility model, is characterized in that the distal ends of welding surfaces of the leads and the electrode pads are bent upward in a certain angle and then are guided out. The improved lead structure, disclosed by the utility model, has the advantages that the force applied to the leads can be completely applied to the whole electrode pads, thus the welding removal of the leads and the electrode pads is greatly avoided, and further the durability of the ceramic heating bar is improved.
Description
Technical field
The utility model relates to ceramic heater; Especially can be applicable to Automobile Detection transducer, vaporizer, electric iron, lambda sensor etc. needs the ceramic heat of heat temperature raising parts excellent; Specifically be the improvement structure to lead-in wire, it is other in the IPC classification, to belong to the big category of H05B3.
Background technology
Ceramic heater is a kind of efficient hot branch uniform heating device; Can guarantee that hot-face temperature is even; The focus and the cold spot of equipment have been eliminated; And have advantages such as long-life, good heat insulating, strong, corrosion-resistant, the diamagnetic field of mechanical performance, being widely used in Automobile Detection transducer, vaporizer, electric iron, lambda sensor etc. needs in heat temperature raising parts or other occasions.
The structure of existing ceramic heat rod is: the ceramic cylinder core body reaches by the curling tubular ceramic layer that forms outside the ceramic cylinder core body that also tightly is placed in of potsherd to be formed; Tubular ceramic layer madial wall is printed with the resistance heating circuit; It is continuous with two electrode pads of lateral wall that these heating circuit two ends pass two apertures of madial wall respectively, is welded with lead-in wire on the electrode pad respectively.
The weak point of existing ceramic heat rod is: two electrode pads of tubular ceramic layer lateral wall are drawn after parallel angle is welded with being of two linear lead-in wires, are prone to go between the stressed part that acts on, and cause to go between and the coming off of electrode pad.
The utility model content
Therefore; The utility model improves design to the unreasonable part of the lead-in wire existence of existing ceramic heat rod; The problem that the welding of solution lead-in wire and electrode pad comes off easily; The power that receives intactly is applied on the entire electrode pad when stressed so that go between, the welding of avoiding greatly going between with electrode pad comes off.
The utility model is realized through following technical scheme:
The electrode pad of ceramic heat rod improves structure; Wherein the ceramic heat rod curls and tightly is placed in the tubular ceramic layer that forms outside the ceramic cylinder core body by the ceramic cylinder core body and by potsherd and forms; Tubular ceramic layer madial wall is printed with the resistance heating circuit; It is continuous with two rectangular electrode pads of lateral wall that these heating circuit two ends pass two apertures of madial wall respectively, is welded with lead-in wire on the electrode pad respectively.Improvements are: the end of the solder side of described lead-in wire and electrode pad is drawn after upwards turning up an angle.
Further, the angle upwards turned up of the end of the solder side of described lead-in wire and electrode pad is 30 ° to 80 °.Lead-in wire adopts 30 ° to 80 ° the angle of turning up, and its stressed effect is better, and is easy to lead-in wire to the stressed dispersion of electrode pad, and the welding of avoiding greatly going between with electrode pad comes off.
The utility model adopts as above technical scheme, and the structure of lead-in wire is improved, and in the time of can making lead-in wire stressed the power that receives intactly is applied on the entire electrode pad, and the welding of avoiding greatly going between with electrode pad comes off.Thereby the durability that makes the ceramic heat rod use is improved.

Embodiment
Combine accompanying drawing and embodiment that the utility model is further specified at present.
Consult illustrated in figures 1 and 2; The ceramic heat rod curls and tightly is placed in the tubular ceramic layer 2 that ceramic cylinder core body 1 outside forms by ceramic cylinder core body 1 and by potsherd and forms; Tubular ceramic layer 2 madial walls are printed with resistance heating circuit 3; This heating circuit two terminal 31 passes two apertures of madial wall respectively and links to each other with two rectangular electrode pads 4 of lateral wall, is welded with lead-in wire 5 on the electrode pad 4 respectively.
Consult shown in Figure 3; Two electrode pads 4 of existing tubular ceramic layer lateral wall are to be to draw after parallel angle is welded with two linear lead-in wires 5 '; Be prone to go between 5 ' the stressed part that acts on electrode pad 4, cause coming off of lead-in wire 5 ' and electrode pad 4.
Consult shown in Figure 4ly, the lead-in wire of the utility model is to be similar " Z " font, promptly goes between 5 after the end of the solder side 401 of itself and electrode pad 4 is upwards turned up an angle, to draw.Preferably, lead-in wire 5 angles upwards turned up are 30 ° to 80 °.Lead-in wire adopts 30 ° to 80 ° the angle of turning up, and its stressed effect is better, and is easy to lead-in wire to the stressed dispersion of electrode pad, and the welding of avoiding greatly going between with electrode pad comes off.
The utility model improves the structure of lead-in wire, in the time of can making lead-in wire stressed the power that receives intactly is applied on the entire electrode pad, and the welding of avoiding greatly going between with electrode pad comes off.Thereby the durability that makes the ceramic heat rod use is improved.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; But the those skilled in the art should be understood that; In the spirit and scope of the utility model that does not break away from appended claims and limited; Can make various variations to the utility model in form with on the details, be the protection range of the utility model.
