伝えない事を目的としている。A circuit diagram and an external view corresponding to FIG. 1 are shown in FIG. In the case of FIG. 1, as can be seen from FIG. 4, no external force is applied to the rectifying element, and stress in that sense is not accumulated in the rectifying element. Therefore, an object of the present invention is to prevent external force applied from the secondary terminal side from being directly transmitted to the rectifying element or the rectifier stack.

スタツク２となっている。）Embodiments of the rear rectifying transformer according to the present invention will be described below. FIG. 4 is an external view showing the schematic configuration thereof. Further, FIG. 1 is a circuit configuration diagram thereof. A direct current is obtained by transforming the AC voltage applied to the input terminal 4 by the transformer 1 and then rectifying it by the rectifying element 12. (In FIG. 4, the rectifying element is assembled into a rectifier stack 2.)

It is well understood that no external force is directly applied to the rectifying element or rectifier stack. Further, since the rectifying element portion is not exposed to the outside as compared with the conventional type, it is protected from dust (particularly dust containing metal powder).

る。Also, for example, in the conventional circuit shown in FIG. 2, it is possible to dispose a rectifying element or a rectifier stack on the back surface of the secondary output terminal, but from the output terminal to the rectifying element or rectifier stack. Since it is necessary to connect between them with a copper band, etc., it is necessary to prepare an extra space by this copper band, and the electrical loss further increases by that amount. Therefore, the external dimensions are increased, the weight is naturally increased, and further, extra heat is generated.

Furthermore, according to the transformer outline drawing and the rear rectification welding transformer shown in FIG. 4, it can be seen in a sheet metal factory, etc. The special effect of protecting the rectifier stack from dust containing metal powder is obtained.
