Electronic apparatus
View Patent ↗According to one embodiment, an electronic apparatus includes a connector electrically connecting a sub-board to a main board, a heat producing component mounted on the sub-board, a heat pipe opposed to the heat producing component, a pressing member, and fixing members. The pressing member includes a main part opposed to the heat pipe, and a plurality of fixing parts extending from the main part and being located closer to the connector than the main part is. The plurality of fixing members fix the fixing parts of the pressing member to the sub-board, and fix the sub-board to support members at positions that are closer to the connector than the main part is.
1. An electronic apparatus comprising:
a housing;
a main board contained in the housing;
a sub-board having a first surface facing the main board, and a second surface on the other side of the first surface;
a connector provided along an edge portion of the sub-board and electrically connecting the sub-board to the main board;
a heat producing component having a first side mounted on the second surface of the sub-board and a second side opposite the first side;
a heat pipe thermally connecting to the second side of the heat producing component;
a pressing member comprising a main part pressing the heat pipe against the heat producing component, a first fixing part located close to a first end portion of the connector, and a second fixing part located close to a second end portion of the connector;
two support members interposed between the main board and the sub-board, and arranged at positions corresponding to the first and second fixing parts of the pressing member; and
two fixing members which fix the first and second fixing parts of the pressing member to the sub-board, and fix the sub-board to the support members at positions that are closer to the connector than the main part is.
2. The electronic apparatus of claim 1 , wherein
each of the fixing parts comprises a first through-hole part,
the sub-board comprises a second through-hole part that communicates with the first through-hole part for each of the fixing parts,
each of the support members is fixed to the main board, and comprises a threaded hole part communicating with the second through-hole part, and
each of the fixing members is inserted in the first through-hole part and the second through-hole part, and is engaged with the threaded hole part.
3. The electronic apparatus of claim 1 , wherein
the fixing parts are arranged in a longitudinal direction of the connector.
4. The electronic apparatus of claim 1 , wherein
the pressing member further comprises a third fixing part with the three fixing parts formed into a substantial Y-shape and the first and second fixing parts formed into a substantial V-shaped part opposed to the connector.
5. The electronic apparatus of claim 1 , wherein
the pressing member further comprises third and fourth fixing parts with the four fixing parts formed into a substantial X-shape and the first and second fixing parts formed into a substantial V-shaped part opposed to the connector.
6. The electronic apparatus of claim 1 , wherein the connector is a stacking connector.
7. An electronic apparatus comprising:
a housing;
a main board contained in the housing;
a sub-board having a first surface facing the main board, and a second surface on the other side of the first surface;
a connector provided along an edge portion of the sub-board and electrically connecting the sub-board to the main board;
a heat producing component having a first side mounted on the second surface of the sub-board and a second side opposite the first side;
a heat radiating member thermally connecting to the second side of the heat producing component;
a pressing member comprising a main part pressing the heat pipe against the heat producing component, a first fixing part located close to a first end portion of the connector, and a second fixing part located close to a second end portion of the connector;
two support members interposed between the main board and the sub-board, and arranged at positions corresponding to the first and second fixing parts of the pressing member; and
two fixing members which fix the first and second fixing parts of the pressing member to the sub-board, and fix the sub-board to the support members at positions that are closer to the connector than the main part is.
8. The electronic apparatus of claim 7 , wherein
each of the fixing parts comprises a first through-hole part,
the sub-board comprises a second through-hole part that communicates with the first through-hole part for each of the fixing parts,
each of the support members is fixed to the main board, and comprises a threaded hole part communicating with the second through-hole part, and
each of the fixing members is inserted in the first through-hole part, and the second through-hole part, and is engaged with the threaded hole part.
9. The electronic apparatus of claim 7 , wherein
the fixing parts are arranged in a longitudinal direction of the connector.
10. The electronic apparatus of claim 7 , wherein
the pressing member further comprises a third fixing part with the three fixing parts formed into a substantial Y-shape and the first and second fixing parts formed into a substantial V-shaped part opposed to the connector.
11. The electronic apparatus of claim 7 , wherein
the pressing member further comprises third and fourth fixing parts with the four fixing parts formed into a substantial X-shape and the first and second fixing parts formed into a substantial V-shaped part opposed to the connector.
