One end of the V-shaped shoulder of the elastic rod 32 is integrally formed with the holder 20, and the V-shaped is narrowed by pressing the other end with a finger. A wedge portion 32a is integrally formed at the tip of the elastic rod 32. Therefore, if the elastic rod 32 is pushed into the attachment / detachment hole 31, the wedge portion 32a is caught and the elastic rod 32 cannot be removed from the attachment / detachment hole 31. If the other end is pushed in the direction of arrow F with a finger, the V-shape narrows and the wedge portion 32a comes out of the attachment / detachment hole 31, and the elastic rod 32 comes out of the attachment / detachment hole 31. That is, the wedge portion 32
By providing a plurality of pairs of attaching / detaching means 30 consisting of a V-shaped elastic rod 32 having a and the attaching / detaching hole 31, the terminal plate 10 and the holder 20 can be fixed facing each other and can be separated. Is. A conventional pair that replaces the attaching / detaching means 30 is
There are many, for example, by splitting the end of a mushroom-shaped thing vertically,
It can be attached / detached even if it is inserted into a round hole, and it may have a structure similar to a hook such as clothes.

While the columnar body 11 is provided on the terminal plate 10, a push plate 21 having a push hole 21a that can be fitted into the columnar body 11 is fixed to the holder 20 via a coil spring 22. Instead of the coil spring, a leaf spring, a disc spring having a plurality of stacked layers, or the like may be used. The detaching force of the attaching / detaching means 30 is made larger than the pressure contact force of the spring 22. The surface of the terminal plate 10 that can be pressed against each other and the pressing plate 2
At least one of 1 and 1 is an electrically conductive conductor. To make the surface of the terminal board 10 electrically conductive, the conductor 12 is molded on the terminal board 10. If there are multiple conductors 12,

[0015]

According to the terminal connecting device for electric equipment of the first aspect of the present invention, since the detaching force of the attaching and detaching means is larger than the pressure contact force of the spring, the attaching and detaching means can be attached and detached by the attaching and detaching means. If you push in, the push plate with a push hole that can be fitted into the columnar body will not come off as it is because the terminal of the electric wire is pressed against the terminal plate by the pressing force of the spring. If you remove the attachment / detachment means,
The terminals can be removed from the terminal board. Therefore, there is an effect that the work of attaching and detaching the terminal of the electric wire to the terminal plate can be easily performed without using a screw.

According to the second aspect of the present invention, when the bar-shaped terminal of the electric wire is inserted into the insertion hole and the attaching / detaching means is attached, the bar-shaped terminal supported by the insertion hole is pressed into contact with the pressing plate so that the pressing plate is electrically conductive. Since it is a conductor of, it has an effect of exhibiting the function of terminal connection. According to the third aspect of the present invention, when the rod-shaped terminal of the electric wire is inserted into the insertion hole and the attaching / detaching means is attached, the rod-shaped terminal supported by the insertion hole opening to the surface of the terminal plate is pressed by the pressing plate and also contacts the terminal plate. However, since at least one of the surface of the terminal plate and the pressing plate is an electrically conductive conductor, there is an effect of exhibiting the function of terminal connection.
