Interposer assembly
An interposer assembly having a housing with contact positioning holes each having a first wall face and a second wall face. The interposer contact has a base portion with shoulder portions and contact arm portions. The base portion is closer to the first wall face. The contact arm portions are once bulged from both respective vertical ends of the base portion toward the first wall face and then curved toward the second wall face. The housing has a retaining protrusion and a pair of slit portions. The retaining protrusion retains the interposer contact inside the contact positioning hole. Each of the shoulder portions is inserted into the slit portion. The slit portion blocks the interposer contact from moving toward the second wall face.
1. An interposer assembly comprising:
a housing having:
(a) an upper face and a lower face parallel to each other,
(b) a plurality of contact positioning holes each having a first wall face and a second wall face facing each other and penetrating in a vertical direction between the upper face and the lower face of the housing,
(c) a pair of slit portions in each of the plurality of contact positioning holes, the slit portions extending from and expanding the contact positioning hole in a widthwise direction transverse to the vertical direction, and
(d) a retaining protrusion formed on the first wall face of each of the plurality of contact positioning holes; and
a plurality of elastically deformable interposer contacts each:
(a) having a vertical dimension longer than a thickness of the housing between the upper face and the lower face while being unloaded,
(b) inserted into each of the contact positioning holes and elastically deformed by pressing a first electronic component toward the upper face and pressing a second electronic component toward the lower face to make electrical connection between the first electronic component and the second electronic component and retained inside the contact positioning hole by the retaining protrusion,
(c) having a base portion having a pair of shoulder portions protruding from both sides in the widthwise direction and positioned closer to the first wall face, and
(d) having a pair of contact arm portions each having one bulge toward the first wall face starting on an upper end or a lower end of the base portion, respectively, then curved toward the second wall face and extending toward each other via upper and lower vertices, respectively;
wherein the base portion is closer to the second wall face than the two bulges.
2. The interposer assembly according to claim 1 , wherein each of the pair of slit portions in the housing has a catching portion catching the shoulder portion of the interposer contact inserted from the upper face to a predetermined position for blocking further insertion of the interposer contact toward the lower face.
3. The interposer assembly according to claim 2 , wherein each interposer contact is spaced from the second wall face of each of the contact positioning holes in the housing both while unloaded and while being pressed by the first component and the second component.
4. The interposer assembly according to claim 3 , wherein the pair of contact arm portions extend substantially vertically starting on both upper and lower ends of the base portion.
5. The interposer assembly according to claim 4 , wherein when the interposer contact is inside the contact positioning hole, the base portion is closer to the first wall face of the contact positioning hole.
6. The interposer assembly according to claim 2 , wherein each of the slit portions terminates at the catching portion in the vertical direction.
7. The interposer assembly according to claim 6 , wherein the catching portion is positioned at a midpoint of the contact positioning hole in the vertical direction.
8. The interposer assembly according to claim 2 , wherein each of the plurality of elastically deformable interposer contacts is simultaneously prevented from moving further toward the lower face of the housing by the pair of slit portions and from escaping through the upper face of the housing by the retaining protrusion.
9. The interposer assembly according to claim 1 , wherein each interposer contact is spaced from the second wall face of each of the contact positioning holes in the housing both while unloaded and while being pressed by the first component and the second component.
10. The interposer assembly according to claim 9 , wherein the pair of contact arm portions extend substantially vertically starting on both upper and lower ends of the base portion.
11. The interposer assembly according to claim 10 , wherein when the interposer contact is inside the contact positioning hole, the base portion is closer to the first wall face of the contact positioning hole.
12. The interposer assembly according to claim 1 , wherein the shoulder portions extend into the slit portions.
13. The interposer assembly according to claim 1 , wherein each of the slit portions extends from the upper face to the lower face in the vertical direction.
14. The interposer assembly according to claim 1 , wherein the first wall face has a retaining protrusion protruding into the contact positioning hole.
15. The interposer assembly according to claim 14 , wherein the retaining protrusion has a slope extending progressively into the contact positioning hole starting at the upper face.
16. The interposer assembly according to claim 1 , wherein each of the plurality of elastically deformable interposer contacts is simultaneously prevented from moving further toward the lower face of the housing by the pair of slit portions and from escaping through the upper face of the housing by the retaining protrusion.
