Abstract

An arrangment in a cellular mobile telephone apparatus includes a protective hatch or flip pivotably arranged on a housing of the apparatus. The flip is pivotable around an axial compartment in the housing and is arranged to physically cover at least part of a front side of the housing. The axial compartment includes a hinge which provides a mechanical connection between the flip and the housing and permits an electrical connection between the microphone and the printed circuit board of the telephone. The electrical connection between the microphone and a printed circuit board in the telephone housing includes a first wiring that leads from the microphone to a first contact. This first contact is fixedly arranged in the ear of the flip. A second contact rotatable in a hole in the axial compartment is connected to a second wiring that leads from the second contact to the printed circuit board of the telephone. When the first and second contacts are fixedly connected, they move together when the flip cover is rotated.

Claims

1. Arrangement at a cellular mobile telephone apparatus, comprising:

a protective flip pivotably arranged on a housing of said apparatus including a microphone, said flip being pivotable around an axle through at least one ear of the flip and arranged to cover at least a part of the front side of the housing,

said axle including hinge means at one end for providing a pivotable, mechanical connection between the flip and the housing as well as establishing an electrical connection between the microphone and the printed circuit board of the telephone along an axis of pivot for the flip,

wherein the electrical connection between the microphone and a printed circuit board of the telephone housing is divided into a first wiring leading from the microphone to a first contacting means, fixedly arranged in the ear of the flip, and a second contacting means fixedly connectable to the first contacting means, and pivotably arranged along the axle of the housing, and from the end of the second contacting means on the inside of the housing, a second wiring leading from the second contacting means to the printed circuit board of the telephone.

2. Arrangement according to claim 1, wherein the microphone is flex-film soldered to the first wiring.

3. Arrangement according to claim 2, wherein the first contacting means is included into a flex-film soldered unit also containing the microphone and the first wiring.

4. Arrangement according to claim 2, wherein the second contacting means is pivotably arranged in an indentation designed in the housing.

5. Arrangement according to claim 4, wherein the second contacting means has two knobs extending in radial directions perpendicular to the axle.

6. Arrangement according to claim 5, wherein the knobs on the contacting means have counterparts in the housing of the telephone to allow the second contacting means to penetrate the bottom of the indentation of the housing.

7. Arrangement according to claim 6, wherein the knobs are diametrically separated and are allowed to penetrate the indentation at an angle of approximately 30°

with regard to a plane parallel to the rear-side plane of the telephone in its assembled state.

8. Arrangement according to claim 1, wherein the second wiring at its end opposite to the second contacting means is attached to the printed circuit board via a disconnectable contact means.

9. Arrangement according to claim 1, wherein the second wiring is freely translatable within its extension limits.

10. Arrangement according to claim 1, wherein the second wiring is at least partly spirally wound.

11. An arrangement in a mobile radio, comprising:

a flip member including;

two opposing cars at one end for pivotally coupling the flip member to a housing about an axis running through the two ears;

a microphone;

a first connector fixedly arranged in one of the ears;

a first conductor coupled to the microphone at one end and to the first connector at the other end,

the housing including;

electronic circuitry for processing signals from the microphone;

a second conductor coupled at one end to the electronic circuitry an axial compartment insertable between the two ears and having a hole at one end such that the flip member is rotatable about the axial compartment;

a second connector rotatable arranged in the hole at the one end of the axial compartment and fixedly connectable via the hole to the first connector to electrically couple the first and second conductors such that when the first and second connectors are connected, the first and second connectors are non-rotatable with respect to each other.

12. The arrangement in claim 11, wherein when the flip member is rotated about the axis, the first connector fixedly arranged in the one ear rotates along with the flip member causing the fixedly connected second connector to rotate together with the first connector.

13. The arrangement in claim 11, wherein rotation of the first connector when connected to the second connector causes the second conductor to twist.

14. Arrangement according to claim 11, wherein the microphone is flex-film soldered to the first conductor.

15. The Arrangement according to claim 11, wherein the second conductor is attached to the electronic circuitry via a disconnectable contact means.

16. The arrangement according to claim 11, wherein the second conductor is freely translatable when the flip member is rotated.

17. The arrangement according to claim 11, wherein the second conductor is at least partly spirally wound.

18. The arrangement according to claim 17, wherein a surface of the hole of the axial compartment includes a corresponding groove for each of the knobs to allow the second connector to penetrate the hole of the axial compartment.

19. The arrangement according to claim 11, wherein the second connector includes two knobs extending in radial directions perpendicular to the axis.

20. Arrangement according to claim 19, wherein the knobs are diametrically separated and are allowed to penetrate the hole at an angle of approximately 30°

with regard to a plane parallel to the housing.
