とがある。Conventional technology In television channel tuners and RF modulators, the shield cover is removably attached to the opening of the shield case that houses the printed wiring, but the partition plate between the shield cover and the shield case is formed by cutting out pieces on the shield cover. (Utility Model Application Publication No. 59-81088). However, such cut-and-raised pieces of the shield cover have openings in the cut-and-raised portions, which may not be sufficient as a measure against leakage of high-frequency signals.

易かつた。Problems to be Solved by the Invention On the other hand, as shown in FIG. the shield cover 3
It is proposed to partially insert it into the hole 4 opened in the hole 4 and connect and secure it with solder 5. In this case, although the shield cover 3 loses its removability due to solder fixation, a complete shield effect and electromechanical contact structure can be obtained. However, in this structure, since the end face of the partition plate 2 is directly inserted into the hole 4 of the shield cover 3, it is difficult for the solder 5 to adhere to both parts, and soldering defects are likely to occur.

法の増加を抑止する。Function In the shield structure of the present invention, the notch of the second shield member is filled with solder in order to obtain a complete shield connection that does not leak high frequency signals. At the same time, the soldering area with the first and second shield members becomes larger, which helps in reliable soldering. In particular, soldering between the bent end of the first shield member and the notch of the second shield member and the recessed part adjacent to the notch improves soldering reliability in that solder flow is prevented. , suppressing increase in external dimensions due to solder build-up.
