Abstract
Official abstract text for this publication.
An electrical device includes a housing, a drive unit arranged inside the housing a substrate arranged inside the housing, and a terminal electrically connecting the substrate with an external portion outside the housing. On the substrate, a circuit driving the drive unit is formed. The terminal includes a terminal protrusion exposed from an inner wall surface of the housing and protruding toward the substrate. The terminal is connected to the substrate at an end portion of the terminal protrusion. The substrate is fixed inside the housing by a first substrate attachment portion and a second substrate attachment portion arranged at a position farther from a connecting portion between the terminal and the substrate than the first substrate attachment portion. The second substrate attachment portion has higher flexibility than the first substrate attachment portion.
First claim
Opening claim text (preview).
What is claimed is: 1 . An electrical device comprising: a housing; a drive unit arranged inside the housing; a substrate arranged inside the housing and on which a circuit configured to drive the drive unit is formed; and a terminal electrically connecting the substrate with an external portion outside the housing, wherein the terminal includes a terminal protrusion exposed from an inner wall surface of the housing and protruding toward the substrate, and is connected to the substrate at an end portion of the terminal protrusion, the substrate is fixed inside the housing by a first substrate attachment portion and a second substrate attachment portion arranged at a position farther from a connecting portion between the terminal and the substrate than the first substrate attachment portion, and the second substrate attachment portion has higher flexibility than the first substrate attachment portion. 2 . The electrical device according to claim 1 , wherein the terminal includes a terminal bent portion between a portion penetrating the housing and the terminal protrusion, and the terminal bent portion is exposed from the inner wall surface of the housing. 3 . The electrical device according to claim 1 , further comprising a terminal metal electrically connecting the drive unit and the substrate, wherein the drive unit is supported by a frame, the terminal metal includes a terminal metal protrusion exposed from the frame, the terminal metal protrusion protrudes toward the substrate, the substrate is connected to an end portion of the terminal metal protrusion, and the terminal metal protrusion is longer than the terminal protrusion. 4 . The electrical device according to claim 3 , wherein the terminal metal includes a terminal-metal bent portion between an end portion connected to the drive unit and the terminal metal protrusion, and the terminal metal protrusion protrudes toward the substrate from the terminal-metal bent portion. 5 . The electrical device according to claim 4 , wherein the terminal metal includes a terminal-metal curved portion having a curved shape between the terminal-metal bent portion and the terminal metal protrusion. 6 . The electrical device according to claim 1 , wherein the first substrate attachment portion protrudes from a partition wall inside the housing, and the first substrate attachment portion is connected to an inner wall surface of the housing via a connecter protruding from a lateral surface of the first substrate attachment portion. 7 . The electrical device according to claim 1 , wherein the second substrate attachment portion protrudes from a partition wall inside the housing, and a lateral surface of the second substrate attachment portion is separated from an inner wall surface of the housing.
