Abstract

The present invention relates to a battery sensor assembly for a vehicle, and more particularly, to a battery sensor assembly for a vehicle, in which a clamp terminal, a shunt resistor, an attachment terminal, and a printed circuit board are easily assembled.

Claims

1. A battery sensor assembly for a vehicle, comprising:

a clamp terminal connected to a negative electrode terminal of a battery;

a shunt resistor connected to the clamp terminal;

a printed circuit board connected to the shunt resistor; and

an attachment terminal connected to the shunt resistor,

wherein a body of the shunt resistor is fixed by sequentially passing through the attachment terminal, the printed circuit board, and the clamp terminal from a lower side.

2. The battery sensor assembly of claim 1, wherein the body of the shunt resistor is formed in a cylindrical shape having a predetermined diameter.

3. The battery sensor assembly of claim 1, wherein the shunt resistor is provided with a head part having a larger diameter than that of the body at an end of a lower side of the body.

4. The battery sensor assembly of claim 1, wherein a nut, which is in contact with an upper surface of the clamp terminal, is fastened to an end of an upper side of the body of the shunt resistor.

5. The battery sensor assembly of claim 1, wherein a riveting part, which is in contact with an upper surface of the clamp terminal, is formed at an end of an upper side of the body of the shunt resistor.

6. The battery sensor assembly of claim 1, wherein a ring-shaped isolator is coupled to an outer peripheral surface of the body of the shunt resistor, so that the shunt resistor is not in contact with the attachment terminal, the printed circuit board, and the clamp terminal.

7. The battery sensor assembly of claim 1, wherein an outer peripheral surface of the body of the shunt resistor is in contact with the attachment terminal, the printed circuit board, and the clamp terminal by any one method of soldering, screw engagement, and pressing.

8. The battery sensor assembly of claim 1, wherein the clamp terminal includes a through hole having a diameter equal to or larger than a diameter of the body of the shunt resistor.

9. The battery sensor assembly of claim 1, wherein the printed circuit board includes a through hole having a diameter equal to or larger than a diameter of the body of the shunt resistor.

10. The battery sensor assembly of claim 1, wherein the attachment terminal includes a through hole having a diameter equal to or larger than a diameter of the body of the shunt resistor.

11. The battery sensor assembly of claim 1, wherein solder patterns are provided between the clamp terminal and the printed circuit board, and between the printed circuit board and the attachment terminal.

12. The battery sensor assembly of claim 1, wherein conductive plates including elastic pieces are provided between the clamp terminal and the printed circuit board, and between the printed circuit board and the attachment terminal.

13. The battery sensor assembly of claim 1, wherein elastic conductive pads are provided between the clamp terminal and the printed circuit board, and between the printed circuit board and the attachment terminal.

14. The battery sensor assembly of claim 1, wherein portions of the clamp terminal, the printed circuit board, and the attachment terminal, through which the shunt resistor passes, are surrounded by a housing together with the shunt resistor.
