機械的な固定作用が同時に行われている。In other words, the rotary operation lever of the connector of the present invention is locked by the spring properties of the contacts, and when the lever is locked, there is electrical contact between the contact portion of the contact and the foil-like conductor of the printed circuit board, and the blade portion of the contact and the printed circuit board. At the same time, mechanical fixing is performed.
前述の実施例ではインシュレータとレバーは一体として
説明したが、これらは別体でもよくこの場合はレバーを
インシュレータに組込んだ状態が製品となる。In the above-mentioned embodiment, the insulator and lever were described as being integrated, but they may be separate bodies, and in this case, the product is a state in which the lever is assembled into the insulator.
またプリント基板の代りにジャパーリード線も用いられ
る。Also, a Japer lead wire can be used instead of a printed circuit board.

の外力が働いても抜は難く極めて信頼性が高い。As mentioned above, according to the connector of the present invention, since the spring properties of each contact are used to lock the lever, a locking force proportional to the number of contact cores can be obtained, and complete electrical contact with the printed circuit board can be made. Since the inserted printed circuit board is fixed by the bite of the blade provided at the free end of the contact, external forces such as tensile force and vibration act on the printed circuit board, compared to conventional connectors that simply press the printed circuit board. It is difficult to remove and is extremely reliable.
さらにインシュレータと回動操作レバーの一体成形品を
使用すれはローコストで済む利点がある。Furthermore, the use of an integrally molded product of the insulator and the rotary operation lever has the advantage of being low cost.
