Description

ROTARY TYPE ELECTRIC COMPONENT}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of rotary electrical components, such as rotary switches, rotary encoders, rotary volumes, and the like, and more particularly to the structure of rotary electrical components having a click mechanism for generating click and rotational torque during rotation.

As a conventional structure of a rotating electrical component having a click mechanism, a rotating body having an operating shaft is provided in a case such as a switch, an encoder, a volume, or a housing main body, and a cam groove having an uneven portion is formed in the circumferential direction of the rotating body. And a click member, for example, a ball, a coil spring, a leaf spring, or the like, is provided so as to slide in contact with the cam groove, and the cam groove and the click member are accompanied by a rotation operation of the operating shaft such as a switch, an encoder, a volume, and the like. Sliding contact produces a click feeling and rotational torque during rotation.

In this case, the cam groove constituting the click mechanism is integrally formed in the rotating body having the operation shaft, and the ball, the coil spring or the leaf spring, which is the click member, is also integrally formed in the case or the housing body. It is received and held in the holding member of the click member.

Therefore, click mechanisms such as switches, encoders, and volumes, which are conventional rotary electric parts, are integrally provided inside the casing or the housing body of switches, encoders, and volumes.

However, in the above-described configuration of the click mechanism of the rotary electric component, the cam groove constituting the click mechanism is integrally formed in the rotating body, and the ball, the coil spring, the leaf spring, and the like, which are the click members, are also used. Since it is held by the holding member integrally formed in the case or the housing main body, in order to obtain various click feelings or rotational torques as necessary, the uneven portion of the cam groove of the rotating plate must be changed or the click member must be changed. In the use of the leaf spring, there is a problem that the mold must be newly pore each time.

In addition, when the click mechanism is changed, the case and the housing main body must also be changed along with it, which causes problems such as an increase in the type of parts and an increase in cost.

Accordingly, in the present invention, the above-mentioned problems are solved, and various clicks are changed by changing a combination of a ball, a coil spring, etc. held by the holding member in one type of component without changing the cam groove of the case, the housing main body, and the rotating body. An object of the present invention is to provide a structure of a rotary electric component having a click mechanism part in which a sense or rotation torque is obtained.
