Substrate holding structure
View Patent ↗Disclosed is a substrate holding structure including: a cylindrical side wall portion that forms an accommodating space; a holding wall portion protruding inward of the accommodating space from the side wall portion; a plurality of press fit terminals held by the holding wall portion, protruding toward an opening of the side wall portion, and pressedly inserted into holes of a substrate accommodated in the accommodating space; and a flexible arm portion protruding toward the opening from a position closer to the side wall portion than the press fit terminals of the holding wall portion, have flexibility, and having a hook portion configured to lock a surface on the opening side of the substrate, wherein distal end positions of the press fit terminals and the arm portion are closer to the holding wall portion than an end surface on the opening side of the side wall portion.
1. A substrate holding structure comprising:
a cylindrical side wall portion that forms an accommodating space;
a holding wall portion protruding inward of the accommodating space from the side wall portion;
a plurality of press fit terminals held by the holding wall portion, protruding toward an opening of the side wall portion, and pressedly inserted into holes of a substrate accommodated in the accommodating space; and
a flexible arm portion protruding toward the opening from a position closer to the side wall portion than the press fit terminals of the holding wall portion, and having a hook portion configured to lock a surface on the opening side of the substrate, wherein
distal end positions of the press fit terminals and the arm portion are located closer to the holding wall portion than an end surface on the opening side of the side wall portion.
2. The substrate holding structure according to claim 1 , further comprising:
a stopper portion that restricts movement of the substrate toward the holding wall portion side beyond a predetermined position.
3. The substrate holding structure according to claim 1 , wherein
the arm portion is inclined with respect to an insertion direction of the substrate toward the accommodating space such that the arm portion is directed inward of the accommodating space as it extends from the holding wall portion toward the opening.
4. The substrate holding structure according to claim 2 , wherein
the arm portion is inclined with respect to an insertion direction of the substrate toward the accommodating space such that the arm portion is directed inward of the accommodating space as it extends from the holding wall portion toward the opening.
5. The substrate holding structure according to claim 1 , wherein
the arm portion abuts the side wall portion in a state where a deformation amount of the arm portion is within an elastic deformation range when the arm portion is pressed toward the side wall portion.
6. The substrate holding structure according to claim 2 , wherein
the arm portion abuts the side wall portion in a state where a deformation amount of the arm portion is within an elastic deformation range when the arm portion is pressed toward the side wall portion.
7. The substrate holding structure according to claim 3 , wherein
the arm portion abuts the side wall portion in a state where a deformation amount of the arm portion is within an elastic deformation range when the arm portion is pressed toward the side wall portion.
8. The substrate holding structure according to claim 4 , wherein
the arm portion abuts the side wall portion in a state where a deformation amount of the arm portion is within an elastic deformation range when the arm portion is pressed toward the side wall portion.
