Abstract

In an electronic apparatus having a first and a second casing part, when the casing parts are rotated relative to each other about a hinge structure, a first and a second sleeve constituting a connector are also rotated relative to each other. A flexible conductive member is received in the sleeves so as to set up electrical connection between circuit portions built in the casing parts. The connector is removable from the circuit portions of the casing parts. In the event of assembly, the electrical connection is set up only if the connector is connected to the circuit portions.

Claims

1. An electronic apparatus comprising:

a first casing part and a second casing part each accommodating a respective circuit portion therein;

a hinge structure which mechanically connects said first casing part and said second casing part such that the casing parts are rotatable relative to each other; and

a connector which electrically connects said circuit portions, said connector contained within a housing having a first end which extends into and insertably engages said first casing part and a second end which extends into and insertably engages said second casing part.

2. An electronic apparatus as claimed in claim 1, wherein the housing of said connector comprises a first sleeve having the first end thereon and a second sleeve having the second end thereon, wherein said first sleeve and said second sleeve are rotatable relative to each other about an axis passing through said first sleeve and said second sleeve, and wherein a flexible conductive member which electrically connects said circuit portions to each other is received in said first sleeve and said second sleeve.

3. An apparatus as claimed in claim 2, wherein said first casing part and said second casing part comprise respective bearings connected together by screws, and wherein said first sleeve and said second sleeve are positioned coaxially with and between said bearings.

4. An apparatus as claimed in claim 2, wherein said flexible conductive member comprises a flexible printed circuit board removably connected to connectors provided in said first casing part and said second casing part, and wherein said first sleeve and said second sleeve comprise respective coupling portions for respectively receiving and supporting opposite ends of said flexible printed circuit board.

5. An apparatus as claimed in claim 2, wherein said first sleeve and said second sleeve rotate in reverse directions relative to one another.

6. An apparatus as claimed in claim 2, wherein a first end of said flexible conductive member resides in the first end of the housing and a second end of said flexible conductive member resides in the second end of the housing, and wherein the first end of said flexible conductive member matably contacts the circuit portion in said first casing part and the second end of said flexible conductive member matably contacts the circuit portion in said second casing part.

7. An apparatus as claimed in claim 6, wherein the first end and the second end of the flexible conductive member matably contact respective circuit portions in said first casing part and said second casing part in a manner which conforms with a PCMCIA standard.

8. An apparatus as claimed in claim 2, wherein said flexible conductive member is a flat cable.

9. An electronic apparatus as recited in claim 1, wherein said hinge structure further includes:

a first set of bearings on said first casing part;

a second set of bearings on said second casing part;

at least one coupling member which couples said first set of bearings to respective ones of said second set of bearings,

wherein said first set of bearings, said second set of bearings, and said coupling member mechanically connect said first casing part to said second casing part, so that said connector bears substantially none of mechanical forces exerted on said hinge structure by said first casing part and said second casing part.

10. An apparatus as claimed in claim 9, wherein the housing of said connector includes two stubs respectively disposed on opposing sides of the housing, said connector being mounted between at least said one of said first set of bearings and said second set of bearings by inserting said stubs into complementary recesses in one of said first set of bearings and said second set of bearings.

11. An apparatus as claimed in claim 10, wherein the housing of said connector is removable from said at least one of said first set of bearings and said second set of bearings when said hinge structure releases said first casing part from said second casing part.

12. An electronic apparatus as recited in claim 1, wherein said connector includes a flexible conductive member for carrying signals between the circuit portions.

13. An electronic apparatus as recited in claim 12, wherein said flexible conductive member is disposed within said hinge structure in a coiled configuration.

14. An electronic apparatus as recited in claim 13, wherein said connector further includes:

a first sleeve rotatably coupled to a second sleeve, with respective portions of said flexible conductive member being disposed within said first sleeve and said second sleeve.

15. An electronic apparatus as recited in claim 14, wherein said flexible conductive member flexes within at least one of said first sleeve and said second sleeve to relieve stresses exerted on said flexible conductive member as a result of said first sleeve rotating relative to said second sleeve.

16. An electronic apparatus as recited in claim 14, wherein said first sleeve and second sleeve form a modular unit.

17. An electronic apparatus as claimed in claim 1, wherein at least one of the first end and the second end of the housing is adapted for coupling to a third casing part which performs at least one function different from said first casing part and said second casing part.

18. An electronic apparatus as recited in claim 1, wherein said electronic apparatus is one of the group consisting of a telephone and a portable computer.

19. An electronic apparatus comprising:

a first casing part and a second casing part each accommodating a respective circuit portion therein;
