Abstract

An electronic unit according to the present invention, the first support member has a first base body, and a first contact member extending from the first base body and making contact with the first main surface of the substrate. The second support member includes a second base body, and a second contact member extending from the second base body and making contact with the second main surface of the substrate. At least part of the area on the first main surface that corresponds to the region at which the second contact member is in contact with the substrate overlaps with the region at which the first contact member is in contact with the substrate. This electronic unit is capable of suppressing distortion in the substrate even when an impact is applied from the exterior. The electrical connection between the electronic component and the substrate can therefore be prevented from being disrupted.

Claims

1. An electronic unit comprising:

a substrate including a first main surface and a second main surface opposite to the first main surface, on which an electronic component is mounted, and

a support member that supports the substrate,

wherein the support member includes a first support member and a second support member, with the substrate being sandwiched between the support members;

the first support member has first side walls disposed on both ends,

the first side walls each have a first side wall end portion,

the first side wall end portions are formed substantially perpendicular to the first side walls, an end surface of each first side wall end portion comes into contact with the first main surface of the substrate,

the second support member has second side walls disposed on both ends,

the second side walls each have a second side wall end portion,

the second side wall end portions are formed substantially perpendicular to the second side walls, an end surface of each second side wall end portion comes into contact with the second main surface of the substrate,

the first side wall end portions, the substrate, and the second side wall end portions are fastened together,

the first support member has a first contact member between the first side walls, and an end portion of the first contact member comes into contact with the first main surface of the substrate,

the second support member has a second contact member between the second side walls, and an end portion of the second contact member comes into contact with the second main surface of the substrate,

at least part of the area at which the first contact member is in contact with the substrate overlaps with a region at which the second contact member is in contact with the substrate, and

the first support member and the second support member are configured substantially to reduce distortion of the substrate in a direction perpendicular to the first main surface and the second main surface.

2. The electronic unit according to claim 1, wherein the first contact member and at least one of the first side walls are formed as a single body.

3. The electronic unit according to claim 1, wherein the second contact member and at least one of the second side walls are formed as a single body.

4. The electronic unit according to claim 1, wherein the first contact member and the second contact member are capable of being in contact with the substrate at the region that experiences the largest amount of distortion.

5. The electronic unit according to claim 1, wherein the center line of the first contact member and the center line of the second contact member are matched, and the center lines are center on the surface of the contact members that is in contact with the substrate.

6. The electronic unit according to claim 1, wherein the first contact member and the second contact member are capable of being in contact with the substrate in the vicinity of the electronic component.

7. An electronic apparatus comprising:

a housing,

an electronic unit that includes a substrate and a support member, the substrate having a first main surface on which an electronic component is mounted and a second main surface opposite to the first main surface, the support member that supports the substrate, the electronic unit being contained in the housing,

wherein the support member includes a first support member and a second support member, with the substrate being sandwiched between the support members;

the first support member has first side walls disposed on both ends,

the first side walls each have a first side wall end portion,

the first side wall end portions are formed substantially perpendicular to the first side walls, an end surface of each first side wall end portion comes into contact with the first main surface of the substrate,

the second support member has second side walls disposed on both ends,

the second side walls each have a second side wall end portion,

the second side wall end portions are formed substantially perpendicular to the second side walls, an end surface of each second side wall end portion comes into contact with the second main surface of the substrate,

the first side wall end portions, the substrate, and the second side wall end portions are fastened together,

the first support member has a first contact member between the first side walls, and an end portion of the first contact member comes into contact with the first main surface of the substrate,

at least part of the area at which the first contact member is in contact with the substrate overlaps with a region at which the second contact member is in contact with the substrate, and

the first support member and the second support member are configured substantially to reduce distortion of the substrate in a direction perpendicular to the first main surface and the second main surface.
