Abstract

A cover for a housing including a number of press-fit pins which have at least two different press-fit zones. A battery sensor including a cover of this kind, and a method for producing a battery sensor are also disclosed.

First claim

The invention claimed is:

1. A cover for a housing, comprising:
a carrier structure, and
a number of press-fit pins which protrude from the carrier structure,
wherein the carrier structure is sheathed by a cover material,
wherein each press-fit pin of a first group of press-fit pins in each case has a first press-fit zone and a second press-fit zone, wherein the first press-fit zone is arranged closer to the carrier structure than the second press-fit zone, and wherein the first press-fit zone has a larger maximum cross-sectional area than the second press-fit zone,
wherein the cover is connected to a first joining partner and a second joining partner, wherein the first joining partner is a measurement resistor and the second joining partner is a printed circuit board, and
wherein the first press-fit zones are pressed into the first joining partner and the second press-fit zones and also press-fit zones of the press-fit pins of a second group are pressed into the second joining partner.

2. The cover as claimed in claim 1 , wherein
the first press-fit zone and the second press-fit zone are respectively at a distance from one another;
or
the first press-fit zone directly adjoins the respective second press-fit zone.

3. The cover as claimed in claim 1 , wherein
the first group comprises four press-fit pins which are arranged in a first pair and a second pair one behind the other.

4. The cover as claimed in claim 1 , wherein
the cover further has an integrated plug.

5. The cover as claimed in claim 1 , wherein
the carrier structure connects a number of press-fit pins to other pins and/or other electrical conductors.

6. The cover as claimed in claim 1 , wherein
the cover is part of a housing which encloses an interior space.

7. The cover as claimed in claim 1 , wherein
the press-fit pins of the first group of press-fit pins are formed in a materially cohesive manner with the carrier structure.

8. The cover as claimed in claim 7 , wherein each press-fit pin of a second group of press-fit pins has a cross-sectional area which is consistently smaller than the maximum cross-sectional area of the first press-fit zone; and
wherein the second group comprises a pair of press-fit pins which are arranged next to one another.

9. The cover as claimed in claim 1 , wherein
each press-fit pin of a second group of press-fit pins has a cross-sectional area which is consistently smaller than the maximum cross-sectional area of the first press-fit zone;
wherein the second group comprises a pair of press-fit pins which are arranged next to one another.

10. The cover as claimed in claim 9 , wherein
further has an integrated plug, and
the press-fit pins of the second group are connected to electrical conductors of the plug.

11. A battery sensor, having
a measurement resistor, and
a measurement circuit which is configured to measure a voltage drop across at least a portion of the measurement resistor,
wherein
the measurement resistor is in the form of part of a housing which encloses the measurement circuit,
wherein the battery sensor has a lower and/or an upper cover, wherein the measurement resistor and the cover or the covers together form the housing, and
wherein at least one of the covers is designed as claimed in claim 1 , the first press-fit zones are pressed into the measurement resistor, and the measurement circuit is mounted on a printed circuit board into which the second press-fit zones are pressed.

12. A method for producing a battery sensor as claimed in claim 11 , the method comprising:
providing a cover comprising:
a carrier structure, and
a number of press-fit pins which protrude from the carrier structure,
wherein the carrier structure is sheathed by a cover material, and
wherein each press-fit pin of a first group of press-fit pins in each case has a first press-fit zone and a second press-fit zone, wherein the first press-fit zone is arranged closer to the carrier structure than the second press-fit zone, and wherein the first press-fit zone has a larger maximum cross-sectional area than the second press-fit zone,
pressing the first press-fit zones into a measurement resistor, and
pressing the second press-fit zones into a printed circuit board.

13. The battery sensor as claimed in claim 11 , wherein at least one of the covers further has an integrated plug, and the press-fit pins of the second group are connected to electrical conductors of the plug and press-fit zones of the press-fit pins of the second group are pressed into the printed circuit board.

14. The battery sensor as claimed in claim 13 , wherein the at least one of the covers comprises four press-fit pins which are arranged in a first pair and a second pair one behind the other, the first pair is arranged in front of the second pair as seen in a direction of current of the battery sensor, a connecting line between the press-fit pins of the first pair is oriented transversely in relation to the direction of current, and a connecting line between the press-fit pins of the second pair is oriented transversely in relation to the direction of current.

15. A method for producing a battery sensor as claimed in claim 13 , the method comprising:
providing a cover comprising:
a carrier structure, and
a number of press-fit pins which protrude from the carrier structure,
wherein the carrier structure is sheathed by a cover material, and
wherein each press-fit pin of a first group of press-fit pins in each case has a first press-fit zone and a second press-fit zone, wherein the first press-fit zone is arranged closer to the carrier structure than the second press-fit zone, and wherein the first press-fit zone has a larger maximum cross-sectional area than the second press-fit zone,
pressing the first press-fit zones into a measurement resistor, and
pressing the second press-fit zones into a printed circuit board.

16. The battery sensor as claimed in claim 11 , wherein the at least one of the covers comprises four press-fit pins which are arranged in a first pair and a second pair one behind the other, the first pair is arranged in front of the second pair as seen in a direction of current of the battery sensor, a connecting line between the press-fit pins of the first pair is oriented transversely in relation to the direction of current, and a connecting line between the press-fit pins of the second pair is oriented transversely in relation to the direction of current.
