る。[Detailed Description of the Invention] The present invention relates to a terminal board for shielded electronic components. FIG. 1 shows an intermediate frequency transformer among shield components to which the present invention is applied. In the figure, 1 is a shield case, 2 is a bobbin, 3 is a coil, 4 is a terminal board, 5 is a terminal, and 6 is a tongue piece provided at the bottom of the shield case 1 for inserting a wiring board.

ることを目的とする。 Incidentally, the lead 7 of the coil 3 wound around the bobbin 2 is wound around the terminal 5 and soldered as shown in FIG. 2, but since the distance between the shield case 1 and the terminal 5 is small, the tip 7' may come into contact with the shield case 1. In order to prevent this, in the conventional intermediate frequency transformer, as shown in FIG. The purpose is to provide a terminal board that is not required.

を押し広げるのに有効に作用する。 A terminal board for a shielded electronic component of the present invention is a shielded electronic component including a terminal board having a protruding terminal on the bottom surface and a lead connected to the terminal. , and is characterized in that a thin protruding side is provided with a notch and its lower end is pushed outward, and the protruding side is brought into elastic pressure contact with the inner surface of the shield case. The embodiment will be described below with reference to FIGS. 4 and 5. The terminal plate 4 of the present invention has a thin protruding side 9 hanging downward around its bottom surface, and has a groove 10 between the protruding side 9 and the periphery of the bottom surface, so that the protruding side 9 can be Notches 11 are also provided at several locations. This protrusion 9 is the fifth
As shown in Figure A, it is elastically pushed outward. The kerf 10 and the notch 11 are the protruding side 9

有する。 Since the terminal board of the present invention has the above-mentioned structure, when the shield case 1 is fitted, the protruding side 9 elastically presses against the inner surface of the shield case 1 and connects with the terminal 5, as shown in FIG. 5B. The terminal 5 is insulated from the shield case 1 to prevent the tip of the lead connected to the terminal 5 from coming into contact with the shield case. Since the protruding side 9 is pushed outward, it is possible to easily wrap the lead 7 of the coil 3 around the base of the terminal 5, and when soldering, the protruding side 9 is pushed outward. It will not be damaged by fire. Further, since the protruding side 9 can be formed by integral molding when molding the terminal plate 4, the productivity is superior to that of the insulating layer 8 shown in FIG. 3, and there is an advantage that it can be provided at a low cost.
