Definitions
- the present disclosure relates to electrical devices.
- Patent Document 1 describes a vehicle sound generator used in a vehicle alarm, a vehicle approach notification device, and the like.
- a current is passed through a voice coil to vibrate a diaphragm connected to the voice coil to generate sound.
- the voice coil is electrically connected to an external harness through metal fittings of the sounding body and terminals of the connector.
- an electric board on which a circuit for driving the sounding body is formed may also be arranged inside the case of the sound generator.
- the terminals and terminal fittings are connected via circuits on this electrical board.
- An electrical device such as the sound generator described in Patent Literature 1 may be mounted, for example, in an engine room of a vehicle, in which case the electrical device is exposed to a temperature environment ranging from low to high. Electrical devices used in such an environment may malfunction due to the stress of expansion and contraction due to temperature changes.
- the present disclosure aims to provide an electrical device capable of suppressing the occurrence of defects in an electrical substrate due to temperature changes.
- An electric device includes an electric board, a housing, a shaft, a concave portion, and an adhesion portion.
- the electrical board has a board hole.
- the housing accommodates the electrical board.
- the shaft portion is arranged in the housing, has a distal end and a proximal end fixed to the housing, and is inserted through the substrate hole.
- the recess is arranged in the housing, fixed to the housing, and has a recessed shape facing the tip of the shaft.
- the bonding portion is interposed between the hole peripheral portion forming the peripheral edge of the substrate hole in the electric substrate and the recess, and between the shaft portion and the recess. and glue.
- the substrate hole is sized so that a gap is formed between the hole peripheral portion and the shaft portion.
- the electric board is held by the adhesive portion and the shaft portion, and the gap between the hole peripheral portion and the shaft portion and the deformation of the adhesive portion prevent the housing and the electric substrate from being separated from each other due to temperature changes. It can absorb expansion and contraction differences. Therefore, bending deformation of the electric board due to the difference in expansion and contraction between the housing and the electric board is less likely to occur than in the case where the shaft portion is fitted into the board hole without a gap, for example. Therefore, it is possible to suppress the occurrence of defects in the electric substrate due to temperature changes.
