Abstract

This application provides a sampling component, including a body portion and a lap portion. The body portion is configured to transmit a sample signal. The lap portion laps the body portion at one end and laps a point for sampling at the other end, to acquire the sample signal; and the lap portion is provided with a fusing structure configured to implement fusing protection on the body portion.

Claims (36)

1 . A sampling component, comprising a body portion and a lap portion, wherein

the body portion is configured to transmit a sample signal; and

the lap portion laps the body portion at one end and laps a point for sampling at the other end, to acquire the sample signal; and the lap portion is provided with a fusing structure configured to implement fusing protection on the body portion;

wherein the lap portion comprises connecting portions and a fusing portion, wherein the connecting portions include a first connecting portion and a second connecting portion, wherein

the first connecting portion is located at one end of the fusing portion to connect the fusing portion to the point of sampling; and the second connecting portion is located at the other end of the fusing portion to connect the fusing portion to the body portion;

wherein the second connecting portion uses a flexible circuit the same as the body portion and the first connecting portion is made of a different material to that of the second connecting portion and has a stronger structural strength to that of the second connecting portion.

2 . The sampling component according to claim 1 , wherein the body portion comprises a wire and an insulation layer, the insulation layer wraps the surface of the wire to isolate the wire, and the wire is exposed from the insulation layer at a position corresponding to the point for sampling, wherein the one end of the lap portion laps the wire at the exposed position.

3 . The sampling component according to claim 1 , wherein the body portion comprises a plurality of wires and a plurality of lap portions, wherein

the wires are exposed from the insulation layer at positions corresponding to points for sampling respectively; and

the one end of each lap portion laps a respective one of the wires at the exposed position.

4 . The sampling component according to claim 1 , wherein the lap portion laps the body portion perpendicularly.

5 . The sampling component according to claim 1 , wherein the fusing portion comprises a chip resistor or a resistance wire.

6 . The sampling component according to claim 1 , wherein the fusing portion comprises an etched wire.

7 . The sampling component according to claim 1 , wherein one of the first and second connecting portions of the lap portion is a flexible flat wire, and a sectional area of the wire in the fusing portion is smaller than that of the wire in the connecting portion.

8 . The sampling component according to claim 1 , wherein the first and second connecting portions and the fusing portion are provided with a laminating film on the surface.

9 . The sampling component according to claim 1 , wherein the second connecting portion is disposed at an exposed position of a wire in the body portion through welding, pressing, riveting or bonding.

10 . A battery, comprising:

a battery cell; and

the sampling component according to claim 1 ,

wherein the sampling component is connected to the battery cell via the lap portion to implement sampling on the battery cell.

11 . An electric apparatus, comprising the battery according to claim 10 , wherein the battery is configured to supply electric energy.

12 . A method for manufacturing a sampling component, comprising:

providing a body portion and a lap portion, wherein the body portion is configured to transmit a sample signal;

making one end of the lap portion lap the body portion and the other end of the lap portion lap a point for sampling to acquire the sample signal; and

providing a fusing structure in the lap portion, wherein the fusing structure is configured to implement fusing protection on the body portion

wherein the lap portion comprises connecting portions and a fusing portion, wherein the connecting portions include a first connecting portion and a second connecting portion, wherein

13 . The method according to claim 12 , wherein the body portion comprises an insulated wire exposed at a position corresponding to the point for sampling, wherein the second connecting portion laps the wire at the exposed position.

14 . A method for sampling a battery, comprising:

providing a lap portion and making one end of the lap portion lap a point for sampling of a battery to acquire a sample signal;

providing a body portion and making the other end of the lap portion lap the body portion to transmit the sample signal to a control system via the body portion; and

providing a fusing structure in the lap portion to implement fusing protection on the body portion when the body portion is short-circuited;

wherein the lap portion comprises connecting portions that include a first connecting portion and a second connecting portion, wherein

the first connecting portion is located at one end of the fusing structure to connect the fusing portion to the point of sampling; and the second connecting portion is located at the other end of the fusing structure to connect the fusing structure to the body portion;
