Abstract

The invention concerns a button cell, particularly for a tire pressure sensor, with a first electric pole formed by a first front side and a second electric pole (4) formed by a second front side opposite to the first front side;

• • with a first contact tab mounted on the first front side, which includes a substantially flat extension inside the plane of the first front side, or with a first contact tab formed by the first front side;
  • with a second contact tab mounted on the second front side, which extends from the plane of the second front side at an angle substantially up to the plane of the first front side;
  • with an insulation layer mounted on the button cell, at least in the region of the first and second contact tabs or over the external periphery of the button cell.

The invention is characterised in that the insulation layer includes a plurality of openings, which traverse the insulation layer completely and which are distributed over the surface of the insulation layer.

Claims

1. A button cell, particularly for a tire pressure sensor, with a first electric pole formed by a first front side and a second electric pole formed by a second front side opposite to the first front side;

with a first contact tab mounted on the first front side, which first contact tab includes a substantially flat extension inside the plane of the first front side or with a first contact tab formed by the first front side;

with a second contact tab mounted on the second front side, which second contact tab extends from the plane of the second front side at an angle substantially up to the plane of the first front side;

with an insulation layer mounted on the button cell, at least in the area of the first and second contact tabs or on the external periphery of the button cell;

characterised in that

the insulation layer includes a plurality of openings, which traverse the insulation layer completely and which are distributed over the surface of the insulation layer.

2. A button cell according to claim 1, characterised in that the insulation layer is designed as a netting.

3. A button cell according to claim 1, characterised in that the insulation layer is designed as a netting tube, in particular a shrink netting tube stretched on the button cell.

4. A button cell according to claim 1, characterised in that the first and/or the second contact tab penetrates the insulation layer and is covered partially by the insulation layer.

5. A tire pressure sensor

with a housing;

with a pressure transducer outside, on or inside the housing;

with transmitting electronics on or inside the housing;

with a power supply;

characterised in that

the power supply contains a button cell according to claim 1.

6. A tire pressure sensor according to claim 5, characterised in that the pressure transducer, the transmitting electronics and the button cell are positioned inside the housing and the housing is filled with a casting compound, at least partially, in particular over its whole base.

7. A tire pressure sensor according to claim 5, characterised in that a circuit board is provided in the housing, on which the button cell is soldered, clamped or fastened otherwise with both contact tabs to provide an electrical contact.

8. A tire pressure sensor according to claim 5, characterised in that the housing is connected in an articulated manner to a tire valve.

9. A button cell according to claim 2, characterised in that the insulation layer is designed as a netting tube, in particular a shrink netting tube stretched on the button cell.

10. A button cell according to claim 2, characterised in that the first and/or the second contact tab penetrates the insulation layer and is covered partially by the insulation layer.

11. A button cell according to claim 3, characterised in that the first and/or the second contact tab penetrates the insulation layer and is covered partially by the insulation layer.

12. A tire pressure sensor

with a housing;

with a pressure transducer outside, on or inside the housing;

with transmitting electronics on or inside the housing;

characterised in that

the power supply contains a button cell according to claim 2.

13. A tire pressure sensor

with a housing;

with a pressure transducer outside, on or inside the housing;

with transmitting electronics on or inside the housing;

with a power supply;

characterised in that

the power supply contains a button cell according to claim 3.

14. A tire pressure sensor

with a housing;

with a pressure transducer outside, on or inside the housing;

with transmitting electronics on or inside the housing;

with a power supply;

characterised in that

the power supply contains a button cell according to claim 4.

15. A tire pressure sensor according to claim 6, characterised in that a circuit board is provided in the housing, on which the button cell is soldered, clamped or fastened otherwise with both contact tabs to provide an electrical contact.

16. A tire pressure sensor according to claim 6, characterised in that the housing is connected in an articulated manner to a tire valve.

17. A tire pressure sensor according to claim 7, characterised in that the housing is connected in an articulated manner to a tire valve.
