Description

本発明は、画像形成装置の各種プロセスユニットとこれらに高電圧を供給する高圧電源を備えた高圧基板とを電気的に接続する高圧接点を保持する高圧接点端子台に関するものである。   The present invention relates to a high-voltage contact terminal block that holds a high-voltage contact that electrically connects various process units of an image forming apparatus and a high-voltage substrate having a high-voltage power source that supplies a high voltage thereto.

電子写真方式によって画像を形成するプリンタや複写機等の画像形成装置には、像担持体ユニット、帯電ユニット、現像ユニット、転写ユニット、クリーニングユニット、定着ユニット等の高電圧を必要とする各種プロセスユニットが設けられているが、これらのプロセスユニットに高電圧を供給するための高圧電源を備えた高圧基板と各種プロセスユニットとは離れた位置にそれぞれ配置されている。   Various image processing units that require high voltage, such as image carrier units, charging units, developing units, transfer units, cleaning units, and fixing units, in image forming apparatuses such as printers and copiers that form images by electrophotography However, the high-voltage substrate provided with a high-voltage power supply for supplying a high voltage to these process units and the various process units are arranged at positions separated from each other.

そこで、高圧接点端子台に保持された複数の高圧接点と高圧基板の各端子とを接続するとともに、各高圧接点に各種プロセスユニットから延びる電線の端部に取り付けられた例えば丸端子を接続することによって各種プロセスユニットと高圧基板とを電気的に接続する方式が採用されている。   Therefore, a plurality of high-voltage contacts held on the high-voltage contact terminal block and each terminal of the high-voltage board are connected, and for example, a round terminal attached to an end of an electric wire extending from various process units is connected to each high-voltage contact. Therefore, a method of electrically connecting various process units and the high voltage substrate is employed.

又、画像形成装置に限らず適用される着脱型の接点端子台についても各種の提案がなされている（例えば、特許文献２，３参照）。
