    摘要: An overcurrent protection apparatus that protects, from overcurrent, a load circuit including an electric load and wiring electrically connected with each other is provided. The overcurrent protection apparatus includes: a semiconductor switching element that is configured to control energization to the load circuit; and a breaker that stops the semiconductor switching element upon detection of abnormality of overheat or overcurrent at the semiconductor switching element, the breaker having a latch operation mode of continuously stopping the semiconductor switching element even upon cancellation of abnormality detection, and a retry operation mode of canceling stoppage of the semiconductor switching element upon the cancellation of the abnormality detection. The breaker is configured to initially operate in the latch operation mode upon the abnormality detection, and then be switched to the retry operation mode after satisfaction of a predetermined condition.

    摘要: An electromagnetic relay includes a casing having a housing space open to an external to the casing through an opening. A base is joined to the casing to close the opening. A coil, a pair of fixed contact elements and a pair of movable contact elements are housed in the housing space. A vent hole set to a dimension making it possible to extinguish flame passing therethrough is formed in a portion where the casing and the base are joined together.

    摘要: A sound generator for a vehicle includes a sounder, a housing surrounding the sounder, a connector unit, a connecting terminal. The sounder includes a diaphragm, a voice coil connected to the diaphragm, and a lead wire extending from the voice coil. The connector unit includes an opening facing toward outside the housing. A vehicle connector is configured to be mounted on the connector unit to electrically connect the connector unit with a device in the vehicle. The connecting terminal is located to protrude inward the housing from the opening of the connector unit. The lead wire extending from the voice coil is directly connected to the connecting terminal in the housing.

    摘要: A piezoelectric sounding element includes a diaphragm made of metal and a piezoelectric element provided on at least one surface of the diaphragm. A non-fixed portion of the diaphragm includes the pair of long sides facing each other, a pair of short sides, shorter than the long sides, that face each other, and a pair of recesses, provided in the pair of long sides, that protrude so as to approach each other. The piezoelectric element is provided in a region between the pair of recesses of the diaphragm and the contour shapes of the non-fixed portion of the diaphragm and the piezoelectric element are defined so as to be symmetric with respect to a first imaginary line that bisects the pair of short sides and symmetric with respect to a second imaginary line that bisects the pair of long sides.

    摘要: A sound generator that generates sound by vibrating a diaphragm includes: a housing including a first space opened to the atmosphere by a sound emission hole and a second space separated from the first space by the diaphragm; and a shield plate disposed in the first space to face the diaphragm while being separated from the diaphragm. When the diaphragm is displaced toward the first space by a pressure difference between the first space and the second space, the diaphragm comes in contact with the shield plate to limit deformation of the diaphragm.

    摘要: In a main magnetic circuit, first pulling force generated based on a first component of the magnetic flux flowing through the main magnetic path pulls a movable core in a reciprocation direction of the movable core. The first pulling force increases with a reduction of a dimension of the gap. In an auxiliary magnetic circuit, second pulling force generated based on the second component of the magnetic flux flowing through the auxiliary magnetic path pulls the movable core in the reciprocation direction of the movable core. In the auxiliary magnetic circuit, the second pulling force with the dimension of the gap being within a first range is changed to be higher than the second pulling force with the dimension of the gap being within a second range, the second range being smaller than the first range.
