摘要： An insert terminal containing case includes a bottom wall, four side walls, and an opening at the upper portion, wherein a terminal made of a metal plate is vertically fixed to at least one of the four side walls by insert molding. A groove is vertically arranged at the outer side surface of the side wall fixing the terminal, the groove extending downward, the outer side surface of the terminal is partially exposed at the groove, and the inner side surface opposite the outer side surface of the terminal exposed at the groove is partially exposed at the inner side surface of the side wall. Therefore, when the terminal is provided in the case by insert molding, molding can be performed only using upper and lower dies. Furthermore, the terminal can be reliably exposed at the inner surface of the side wall. The insert terminal containing case has the minimum difference between the opening dimension of the case and the dimension of a piezoelectric diaphragm and is molded without using a sliding die.
摘要翻译：插入式端子容纳壳体包括底壁，四个侧壁和在上部的开口，其中由金属板制成的端子通过嵌入成型垂直地固定到四个侧壁中的至少一个。在固定端子的侧壁的外侧表面上垂直设置有槽，槽向下延伸，端子的外侧表面部分地暴露在槽处，并且与端子的外侧表面相对的内侧表面在侧壁露出的部分露出在侧壁的内侧面。因此，当通过插入成型将端子设置在壳体中时，可以仅使用上模具和下模具进行模制。此外，端子可以可靠地暴露在侧壁的内表面。插入式端子容纳盒在壳体的开口尺寸和压电膜片的尺寸之间具有最小的差异，并且在不使用滑动模具的情况下被模制。

摘要： A piezoelectric electroacoustic transducer includes a piezoelectric sounding body in which bending vibration is generated by applying an alternating signal between two electrodes, a case housing the piezoelectric sounding body, and a pair of terminals insert-molded in the case. In the piezoelectric electroacoustic transducer, internal connection portions of the pair of terminals are exposed on the inside surface of the side wall portion of the case so as to extend in a direction that is substantially perpendicular relative to the piezoelectric sounding body, and the internal connection portions of the terminals are electrically connected to the electrodes of the piezoelectric sounding body by using conductive adhesive. The internal connection portions of the terminals do not largely extend inside the case and accordingly, the dimensional difference between the case and the piezoelectric sounding body is minimized.
摘要翻译：压电式电声换能器包括：压电发声体，其中通过在两个电极之间施加交变信号产生弯曲振动，容纳压电发声体的壳体和嵌入成型在壳体中的一对端子。在压电电声换能器中，一对端子的内部连接部分暴露在壳体的侧壁部分的内表面上，以便在相对于压电发声体基本上垂直的方向上延伸，并且内部连接端子的部分通过使用导电粘合剂电连接到压电发声体的电极。端子的内部连接部分在壳体内部没有大的延伸，因此壳体和压电发声体之间的尺寸差最小化。

摘要： A package of a surface-mountable electronic component to be reflow-soldered to a circuit board at about 250° C. or more includes a case and a cover. The cover has a softening temperature lower than the reflow temperature, and the case has a softening temperature higher than the reflow temperature. In the package, softening the cover compensates for the stress on the bonded surfaces resulting from a difference in thermal expansion between the case and the cover caused during reflow.
