Kunshan spring: Battery spring is one of the important components of the connection between the battery and the appliance, its role is to connect the positive and negative terminals of the battery and the appliance lead wire terminals, so that the appliance can work properly.

In the purchase of battery springs, you need to consider a variety of factors, including size, material, elasticity, conductivity and so on.

In this article, we will introduce how to select the right battery spring, I hope to help our readers.

First, the size

When shopping for battery springs, you first need to understand the size of the battery spring.

The size of the battery spring should match the model of the battery, otherwise it can not be used. Usually, the size of the battery spring is determined by its length, width, height and shape. When purchasing a battery spring, you need to pay attention to the following points:

1. The length of the battery spring should match the battery, otherwise it cannot be connected properly.

2. The width of the battery spring should be the same as or slightly larger than the width of the battery pole piece to ensure a solid connection. If the width of the battery spring is too small, it is easy to break or lead to poor contact.

3. The height of the battery spring should be matched with the wire terminals of the appliance to ensure a solid connection. If the height of the battery spring is too high, it will easily lead to poor contact or short circuit.

Second, the material

The material of the battery spring is also one of the important factors to consider when purchasing.

Battery spring is usually made of metal materials, commonly used materials are steel, copper, phosphor bronze, aluminum and so on. Different materials have different characteristics of the battery spring, need to be selected according to the specific circumstances:

1. Steel: steel battery spring hardness, poor elasticity, short service life.

2. Copper: copper battery spring conductivity, elasticity is better, longer service life.

3. Phosphor bronze: phosphor bronze material battery spring in the conductivity and elasticity are good performance, long service life.

4. Aluminum: aluminum battery spring lightweight, conductive, but less flexible, easy to break.

Third, elasticity

The elasticity of the battery spring is also one of the factors to consider when buying. Good elasticity of the battery spring can better fix the battery, and ensure the stability of the connection. Generally speaking, the elasticity of the battery spring is related to its material, thickness, design and so on. When shopping, you can identify the elasticity of the battery spring in the following ways:

1. Gently bend the battery spring with your hand to see its ability to return to its original state. A battery spring with good elasticity should be able to return to its original shape quickly.

2. Press the spring gently with the tip of your finger to see how hard it bounces back. Good elasticity of the battery spring should rebound strength, comfortable feel.

Fourth, conductivity

Battery spring conductivity is also one of the important factors to consider when purchasing. Good conductivity of the battery spring can ensure the normal operation of electrical appliances. In the purchase of battery springs, you should pay attention to the following points:

1. You should choose a battery spring made of metal material with good electrical conductivity.

2. Battery springs with smooth surfaces should be selected to ensure that they are not obstructed when connected to electrical appliances.

3. When connecting the battery spring and electrical appliances, you should ensure that the contact surface between the connecting terminals is smooth and clean to ensure excellent conductivity.

In short, when shopping for battery springs, you need to consider a number of factors, including size, material, elasticity, conductivity and so on.

Only buy the right battery spring, to ensure that the normal operation of electrical appliances, and safe and reliable.
