画像形成装置において従来用いられている高圧接点端子台においては、これに保持された高圧接点には、高圧基板の各端子に弾性的に接触して所定の接触圧を保持することができる板バネが使用され、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端子と板バネとをネジ等の締結部品で締結する構成が採用されていたため、端子の板バネへの取り付け及び取り外しが面倒で、多くの高圧接点が設けられたカラー画像形成装置等においては、その作業に多くの時間を費やし、作業能率が悪いという問題があった。   In a high-voltage contact terminal block conventionally used in an image forming apparatus, a leaf spring that can hold a predetermined contact pressure by elastically contacting each terminal of a high-voltage substrate is connected to the high-voltage contact held by the terminal block. Is used, and the terminal and leaf springs attached to the ends of the wires extending from the various process units are fastened with fastening parts such as screws, so it is troublesome to attach and remove the terminals to and from the leaf springs. In a color image forming apparatus provided with many high-voltage contacts, there is a problem that a lot of time is spent on the work and work efficiency is poor.

本発明は上記問題に鑑みてなされたもので、その目的とする処は、各種プロセスユニットと高圧基板とを簡単且つ効率良く接続することができる高圧接点端子台を提供することにある。   The present invention has been made in view of the above problems, and an object of the present invention is to provide a high voltage contact terminal block capable of easily and efficiently connecting various process units and a high voltage substrate.

上記目的を達成するため、請求項１記載の発明は、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おいて、前記高圧接点をバネ接点で構成するとともに、該バネ接点にＶ字状部を形成し、前記プロセスユニットと前記高圧基板とを接続する電線の一端に取り付けられた丸端子を前記バネ接点のＶ字状部に係合させて固定するようにしたことを特徴とする。   In order to achieve the above object, the invention described in claim 1 is a high voltage circuit for holding a high voltage contact for electrically connecting various process units of the image forming apparatus and a high voltage substrate having a high voltage power source for supplying a high voltage thereto. In the contact terminal block, the high-voltage contact is constituted by a spring contact, a V-shaped portion is formed in the spring contact, and a round terminal attached to one end of an electric wire connecting the process unit and the high-voltage substrate is It is characterized by being engaged and fixed to the V-shaped part of the spring contact.

請求項２記載の発明は、請求項１記載の発明において、前記バネ接点のＶ字状部以外の部位を前記高圧基板に接触させることを特徴とする。   According to a second aspect of the present invention, in the first aspect of the present invention, a portion other than the V-shaped portion of the spring contact is brought into contact with the high-pressure substrate.

請求項１記載の発明によれば、プロセスユニットと高圧基板とを接続する電線の一端に取り付けられた丸端子をバネ接点のＶ字状部に押し当てれば、バネ接点のＶ字状部が弾性変形して丸端子の移動を許容し、丸端子の円孔がバネ接点のＶ字状部を通過した時点でバネ接点のＶ字状部が弾性によって元の状態に復帰して丸端子の円孔に係合し、これによって丸端子が固定されてバネ接点に接続されるため、単に丸端子を高圧接点端子台に押し込むだけの簡単な操作で該丸端子をワンタッチで容易にバネ接点に接続することができ、電線を介して各種プロセスユニットと高圧基板とを簡単且つ効率良く接続することができる。   According to the first aspect of the present invention, if the round terminal attached to one end of the electric wire connecting the process unit and the high voltage substrate is pressed against the V-shaped portion of the spring contact, the V-shaped portion of the spring contact is elastic. When the round terminal is deformed to allow movement and the round hole of the round terminal passes through the V-shaped part of the spring contact, the V-shaped part of the spring contact returns to its original state due to elasticity and the circle of the round terminal Since the round terminal is fixed and connected to the spring contact by engaging with the hole, the round terminal can be easily connected to the spring contact with a single operation by simply pushing the round terminal into the high-voltage contact terminal block. The various process units and the high-voltage board can be easily and efficiently connected via the electric wires.

請求項２記載の発明によれば、バネ接点のＶ字状部以外の部位を高圧基板に接触させることによって高圧基板をバネ接点と丸端子及び電線を介してプロセスユニットに接続することができる。   According to invention of Claim 2, a high voltage board | substrate can be connected to a process unit via a spring contact, a round terminal, and an electric wire by making parts other than the V-shaped part of a spring contact contact a high voltage board.

The electric wire 4 is electrically connected by the high voltage contact terminal block 1 according to the present invention.

本発明に係る上記高圧接点端子台１は、図４及び図５に示すように、本体フレーム３に外方から差し込まれて固定されており、図６に詳細に示すように、絶縁性の高い樹脂にて一体成形された接点保持部材９を有している。   As shown in FIGS. 4 and 5, the high-voltage contact terminal block 1 according to the present invention is fixed by being inserted into the main body frame 3 from the outside. As shown in detail in FIG. The contact holding member 9 is integrally formed of resin.
