Abstract

According to one embodiment, an electronic device includes a casing, a flexible wiring member, and a first electrical component, for example. The casing is provided with an opening. The flexible wiring member includes an insulating film, a lead mounted on the insulating film, and a connection terminal, and extends through the opening. The sealant is filled in the opening. The first electrical component is encapsulated by the casing and electrically connected to a second electrical component outside the casing through the flexible wiring member.

Claims

a casing provided with an opening;

a flexible wiring member that extends through the opening;

a sealant filling the opening; and

an outer electrical component being outside the casing and electrically connected to the flexible wiring member.

2. The hard disk drive according to claim 1, wherein the casing is hermetically sealed.

3. The hard disk drive according to claim 2, wherein the casing is filled with gas different from air.

4. The hard disk drive according to claim 3, wherein the gas includes helium.

5. The hard disk drive according to claim 1, wherein the flexible wiring member comprises two flexible wiring members which are extending in a direction away from each other in at least outside of the casing.

6. The hard disk drive according to claim 5, wherein the two flexible wiring members are coupled in the opening.

7. The hard disk drive according to claim 6, further comprising:

a connection interposed between and coupling the two flexible wiring members in the opening.

8. The hard disk drive according to claim 7, wherein the two flexible wiring members are electrically connected through a conductive portion which is extending through a via in the connection.

9. The hard disk drive according to claim 7, wherein the connection has insulating property.

10. The hard disk drive according to claim 1, wherein the flexible wiring member is provided on an outer face of the casing.

11. The hard disk drive according to claim 1, wherein the flexible wiring member is a flexible printed circuit board.

12. The hard disk drive according to claim 1, wherein

the outer electrical component includes a circuit board mounted on an outer face of the casing, and a connector mounted on the circuit board and electrically connected to the flexible wiring member.

13. The hard disk drive according to claim 12, wherein the connector includes an elastic contact that is elastically deformed and electrically connected to a contact on the flexible wiring member.

14. The hard disk drive according to claim 13, wherein the contact includes two rows of contacts.
