Abstract

There is provided an accumulator unit for insertion into a portable electronic device. The accumulator unit has an integrated charging unit and a charging port. The charging port is freely accessible in the inserted and non-inserted condition of the accumulator unit.

Claims (58)

1. An accumulator unit for insertion into a portable electronic device comprising:

a housing;

an integrated charging unit; and

a freely accessible charging port adapted to receive a plug of a charging cable;

wherein the housing of the accumulator unit is of a cuboidal configuration, the housing having

a top side;

an underside;

a first side wall;

a second side wall;

a front side; and

a rear side;

wherein the area of the top side and the underside is respectively at least three times as great as the area of the first or second side wall, a left-hand side wall, and/or the rear side;

wherein the rear side has a first contact surface and a second contact surface for providing an electrical voltage at the respective ends of the rear side;

wherein the front side has a projection having a wall arranged at an angle of between 5 and 45° relative to the rear side; and

wherein the charging port is arranged at said wall such that a removal direction of the accumulator unit from the portable electronic device is different from a removal direction of the plug from the charging port, so that the accumulator unit is removed from the portable electronic device when a cable extending from the plug is pulled in the removal direction of the accumulator unit.

2. The accumulator unit as set forth in claim 1 ;

wherein the charging port represents a standardized micro USB port.

3. The accumulator unit as set forth in claim 1 ;

wherein the rear side centrally has a nose.

4. The accumulator unit as set forth in claim 1 ;

wherein the top side has at least one nose serving for latching engagement of the accumulator unit in a receiving unit.

5. A portable electronic device comprising:

a receiving compartment for receiving an accumulator unit; and

an accumulator unit as set forth in claim 1 .

6. The portable electronic device as set forth in claim 5 ;

wherein the receiving compartment has electrical connections which can co-operate with electrical connections when the accumulator unit is inserted into the receiving compartment.

7. An ear phone comprising:

an accumulator unit having:

a housing;

an integrated charging circuit; and

a charging port which is freely accessible in the inserted state, and which is adapted to receive a plug of a charging cable; and

a receiving compartment for receiving the accumulator unit;

wherein the receiving compartment and the accumulator unit are of such a design configuration that a frictional action between the receiving compartment and the accumulator unit is less than a frictional action between a plug of a charging cable and the charging port; and

wherein the charging port is arranged at an angle of between 5 and 45° relative to the accumulator unit such that a removal direction of the accumulator unit from the ear phone is different from a removal direction of the plug from the charging port, so that the accumulator unit is removed from the ear phone when a cable extending from the plug is pulled in the removal direction of the accumulator unit.

8. An ear phone comprising:

an accumulator unit having:

a housing;

an integrated charging circuit; and

a charging port which is freely accessible in the inserted state, and which is adapted to receive a plug of a charging cable; and

a receiving compartment for receiving the accumulator unit;

wherein a holding force between the receiving compartment and the accumulator unit is less than a holding force between a plug of a charging cable and the charging port; and

wherein the charging port is arranged at an angle of between 5 and 45° relative to the accumulator unit such that a removal direction of the accumulator unit from the ear phone is different from a removal direction of the plug from the charging port, so that the accumulator unit is removed from the ear phone when a cable extending from the plug is pulled in the removal direction of the accumulator unit.

9. An ear phone comprising:

an accumulator unit having:

a first center line;

a housing;

an integrated charging circuit; and

a charging port which is freely accessible in the inserted state, and which is adapted to receive a plug of a charging cable;

a receiving compartment for receiving the accumulator unit; and

a plug of a charging cable, which can be plugged into the charging port, the plug having a second center line;

wherein an angle between the first and second center lines is between 5 and 45° such that a removal direction of the accumulator unit from the ear phone is different from a removal direction of the plug from the charging port, so that the accumulator unit is removed from the ear phone when a cable extending from the plug is pulled in the removal direction of the accumulator unit.

10. An accumulator unit for insertion into a portable electronic device comprising:

a housing having a front side and a rear side;

an integrated charging unit; and

a freely accessible charging port adapted to receive a plug of a charging cable;

wherein the rear side has a first contact surface and a second contact surface for providing an electrical voltage at the rear side;

wherein the front side has a section arranged at an angle of between 5 and 45° relative to the rear side; and

wherein the charging port is arranged at said section such that a removal direction of the accumulator unit from the portable electronic device is different from a removal direction of the plug from the charging port, so that the accumulator unit is removed from the portable electronic device when a cable extending from the plug is pulled in the removal direction of the accumulator unit.
