度当りによる騒音を防止するようにしたソレノイドに関
する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solenoid, and more particularly to a solenoid which prevents noise caused by a hit between an armature and a yoke which occurs when the armature returns.

命を高めることを目的とするものである。The former (FIG. 4) described in the prior art requires a separate arm for mounting a cushioning member, and the latter requires processing such as bending the armature base to the side of the yoke. The disadvantage that the cost is inevitably high due to the necessity is inevitable. Therefore, the present invention also has a structure which absorbs the noise generated when the armature is returned by using the buffer member. In particular, in the present invention, the buffer member is used, and this type of solenoid swings the armature around the fulcrum shaft of the yoke. It is an object of the present invention to prevent a stiffness between the fulcrum shaft and the armature fitting portion, which is likely to be caused by the structure in which the armature is movably fitted and supported, to prevent wear of both, and to increase the operating life of the armature. .

And the other end of the armature, which is always biased to return by a spring, is swingably fitted and supported, and a buffer member such as rubber which causes the armature to hit upon return of the armature is provided. Is interposed in a gap between a fulcrum shaft of the yoke and a fitting portion of an armature fitted to the shaft.

ソレノイドの一般的形態である。DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 1 denotes a yoke having an L-shaped side surface. An exciting body 4 comprising an exciting coil 2 and an iron core 3 is attached to a horizontal plate of the yoke 1, and an upper end of a vertical plate of the yoke 1. On both sides, a narrow plate-shaped fulcrum shaft 5 is protruded by the plate portion. On the fulcrum shaft 5, notched U-shaped fitting portions 7 formed on both side edges of the base of the armature 6 are swingable. It is loosely inserted.
The front end surface of the armature 6 is freely attracted to the iron core 2, and the yoke 1 is attached to the rear end of the armature 6.
This is a general form of such a solenoid, which locks the other end of a spring 8 having one end fixed thereto, thereby always restoring the armature 6.

時の騒音をも阻止するものである。According to the excitation of the solenoid, the armature 6 pivots on the fulcrum shaft 5 and swings against the spring 8 and is attracted to the iron core 2. When the suction is released, the armature 6 is restored by the restoring force of the spring 8. Is done. In this return state, the two diagonal corners 7a and 7b of the fitting portion 7 of the armature hit the fulcrum shaft via the cushioning member 9 and thus come to the fulcrum shaft 5 at the corners 7a and 7b. And the noise at the time of the return of the armature 6 is also prevented by hitting the corner edges 7a and 7b against the buffer member 9.

供することができる。According to the present invention as described above, the following effects are obtained. (A) Since the buffer between the armature and the armature fitted on the shaft is interposed in the gap between the fulcrum shaft of the yoke and the fitting portion of the armature, noise can be prevented by returning the armature. In particular, to prevent wear of both the fulcrum shaft and the armature fitting part to prevent wear,
Thus, the operating life of the armature can be increased. (B) Since no special member or process is required for mounting the cushioning member, there is no cost increase and the device can be provided at low cost.
