Substrate connection structure
A substrate connection structure includes a first substrate, a second substrate, a first connection terminal plate, a second connection terminal plate, and a fastening member. The first connection terminal plate extends away from the first substrate and includes a flat portion. The second connection terminal plate extends away from the second substrate and includes a flat portion. At least one of the flat portions includes a screw insertion portion. The fastening member fastens the first connection terminal plate and the second connection terminal plate through the screw insertion portion in a state in which the flat portions are in contact with each other.
1. A substrate connection structure comprising:
a first substrate including two opposite surfaces, wherein a semiconductor element is mounted on at least one of the two surfaces;
a second substrate facing the first substrate and including two opposite surfaces, wherein a semiconductor element is mounted on at least one of the two surfaces;
a first connection terminal plate extending away from the first substrate, wherein the first connection terminal plate includes a basal end, which is fixed to the first substrate, and a flat portion;
a second connection terminal plate extending away from the second substrate, wherein the second connection terminal plate includes a basal end, which is fixed to the second substrate, and a flat portion, and at least one of the flat portions includes a screw insertion portion; and
a fastening member that fastens the first connection terminal plate and the second connection terminal plate through the screw insertion portion in a state in which the flat portions are in contact with each other.
2. The substrate connection structure according to claim 1 , wherein
one of the first and second connection terminal plates includes the screw insertion portion,
the other one of the first and second connection terminal plates includes a threaded hole engaged with the fastening member, and
the screw insertion portion is larger than the threaded hole.
3. The substrate connection structure according to claim 1 , wherein at least one of the first and second connection terminal plates includes a tolerance accommodation portion that deforms to allow the first and second substrates to approach each other and accommodate tolerance.
4. The substrate connection structure according to claim 3 , wherein the tolerance accommodation portion includes a slot formed in the corresponding connection terminal plate.
5. The substrate connection structure according to claim 1 , wherein
the first connection terminal plate includes a leg portion, which extends from the basal end toward the second substrate, and wherein the flat portion of the first connection terminal plate extends from a tip end of the leg portion parallel to the first substrate, and
the second connection terminal plate includes a leg portion, which extends from the basal end toward the first substrate, and wherein the flat portion of the second connection terminal plate extends from a tip end of the leg portion of the second connection terminal plate parallel to the second substrate.
