摘要: In an electromagnetic relay device, a stationary core is coaxially arranged in an exciting coil, and constitutes a magnetic circuit. A yoke is arranged to surround an outer periphery of the exciting coil and the second end of the exciting coil to constitute the magnetic circuit. The yoke has an opening that is located to be closer to the first end of the exciting coil than to the second end of the exciting coil, and that faces the stationary core. A movable core is located to face the stationary core via the opening. The movable core is pulled to the stationary core upon the exciting coil being energized. A return spring is made of a magnetic member that is volutely wound in an axial direction of the stationary core. The return spring urges the movable core to be separated from the stationary core.

摘要: An electromagnetic relay includes: a coil; a housing that supports the coil; a non-movable portion supported by the housing and including a fixed core and a fixed magnetic path defining member; and a movable portion provided to be reciprocally movable along a center axis line of the coil according to an energization state of the coil. The movable portion includes a movable core disposed to face the fixed core along the center axis line. The movable portion integrally has a flange portion protruding in a coil radial direction perpendicular to the center axis line to define a separation distance and/or a facing area in a magnetic gap between the fixed magnetic path defining member and the movable core by abutting against the non-movable portion.

摘要: A stationary core is in an exciting coil. A yoke covers an outer periphery and an axial end of the exciting coil to form a magnetic circuit and has an opening portion. The movable core faces the stationary core through the opening portion and is attracted toward the stationary core on energization of the exciting coil. A return spring urges the movable core against the attraction direction. A first gap is formed between the stationary core and the movable core on deenergization of the exciting coil. A second gap is formed between the yoke and the movable core on deenergization of the exciting coil. The second gap allows the yoke and the movable core to generate an attractive force therebetween on energization of the exciting coil. The return spring is made of a magnetic material to magnetically bridge the first gap or the second gap.

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: 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.

摘要: A vehicle approach alert device includes: a memory memorizing a warning sound source data for emitting a warning sound from an external sound emitting unit and a canceling sound source data for emitting a canceling sound from an internal sound emitting unit. The canceling sound cancels the warning sound transmitted from the external sound emitting unit to inside of the vehicle. The vehicle approach alert device further includes: a control part configured to read the warning sound source data from the memory to cause the external sound emitting unit to emit the warning sound based on the warning sound source data, and to read the canceling sound source data from the memory to cause the internal sound emitting unit to emit the canceling sound based on the canceling sound source data to be synchronized with the warning sound.
