端子部に接触する誤接続のおそれがあり、また端子部を
幅狭にすれば接触金具も小さくしなければならないので
充分な接触面積が得られず、接触抵抗が大きい欠点が生
じる。(Problem to be solved by the invention) Equipment incorporating heaters, such as copying machines and facsimile machines, are required to be more and more compact, and accordingly, heaters are also becoming smaller.
In this case, the terminal part also needs to be formed narrowly, making it necessary to tighten manufacturing accuracy tolerances, and also to prevent the contact fittings of the socket from coming into contact with adjacent terminal parts. There is a risk of connection, and if the width of the terminal portion is made narrower, the contact fittings must also be made smaller, so that a sufficient contact area cannot be obtained, resulting in a drawback of high contact resistance.
さらに、近年に到り、発熱部を中間部の複数個所から分
岐し、分岐されたそれぞれの導電部を基板の端部に延在

である。このものは複数の端子部を幅狭い基板の端縁に
並設したので、個々の端子部がさらに小形になり、かつ
端子部間の間隔も狭くなり。Furthermore, in recent years, the heating section has been branched from multiple locations in the intermediate section, each branched conductive section has been extended to the edge of the board, and multiple terminal sections have been connected to these multiple conductive sections, respectively. A heater was developed that was placed parallel to the edge of the board. This product allows you to freely select the heated length (effective length) of one heating section by selecting the required terminal section and energizing it according to the size of the object to be heated, such as copy paper. This is to ensure safety by ensuring that the temperature does not rise in areas that do not come into contact with each other. In this device, a plurality of terminal portions are arranged side by side on the edge of a narrow substrate, so each terminal portion becomes smaller and the distance between the terminal portions becomes narrower.
このため、製造精度誤差は一段と厳しく、誤接続がより
多く発生しやすく、かつ接触抵抗がより大きくなり接触
金具の損耗が激しい欠点がある。For this reason, manufacturing accuracy errors are more severe, erroneous connections are more likely to occur, contact resistance is increased, and the contact fittings are subject to severe wear and tear.
そこで、本発明の課題は個々の端子部を可及的に大きく

大幅に増加し、端子部を大きくしたものである。(Means for Solving the Problems) The present invention relates to an improvement of a heater in which an electric heating element including a heating part and a terminal part is formed on the surface of an elongated heat-resistant substrate along the longitudinal direction of this board. No. 1 is a device in which a plurality of terminal portions are arranged side by side on the side edge of the substrate, thereby increasing the width of the terminal portion by arranging the terminal portions side by side in the length direction with a relatively large margin. A second aspect of the present invention provides a device in which a plurality of terminal portions are arranged separately on both the front and back surfaces of the substrate, thereby greatly increasing the area in which the terminal portions can be installed and making the terminal portions larger.
さらに、請求項の第３は端子部のうち少なくとも１個を
複数に分岐して基板の表裏両面に分けて配置したことに
より、端子部の面積を実質的に太きくしたものである。Furthermore, in a third aspect of the present invention, at least one of the terminal parts is branched into a plurality of parts and disposed separately on both the front and back surfaces of the board, thereby substantially increasing the area of the terminal part.

By arranging the terminal portions in the direction, the area of the terminal portions and the distance between them can be made large, so the contact resistance can be reduced by making the contact fittings large, eliminating erroneous contacts, and when forming the terminal portions. The margin for dimensional errors can be increased. In addition, since the second plurality of terminal parts are arranged separately on both the front and back surfaces of the board, the area of each terminal part and the interval between them can be made large, and the contact fitting with the socket can be made large to make contact. Reduces resistance, eliminates erroneous contacts, and provides 1.
The margin for dimensional errors can be increased. Furthermore, the third aspect of the present invention is that at least one of the terminal parts is branched into a plurality of parts and disposed separately on both the front and back surfaces of the board, so that the terminal part becomes substantially larger and the contact resistance can be reduced. The margin for dimensional errors can be increased.
