What are the precautions for button battery holders?

Button batteries are widely used in various delicate components. Everyone must be familiar with the use of button batteries, and they are often seen in daily life. In fact, these are the benefits brought by technological progress, allowing such a small battery to play such a big role. When it comes to button batteries, we have to mention the issue of battery holders. The battery holder plays a very important role in button batteries. Many people simply call it a button battery holder. So, what are the precautions for button battery holders?

What are the precautions for button battery holders?

1. When choosing a button battery, pay attention to the diameter and thickness (height) of the battery, and choose according to the requirements of the installed electrical products;

2. Because the types of materials used in button batteries are different, it is determined according to the electronic products;

3. During use, prevent the positive and negative positions from being reversed;

4. It is not allowed to use a soldering iron to weld the leads on the battery;

5. It is forbidden to burn used batteries in the fire, because this will increase the battery temperature and cause the battery to burst;

6. Unless otherwise specified, button batteries are basically disposable batteries and cannot be charged to avoid bursting;

7. Try to avoid using button batteries in high temperature environments to reduce battery discharge losses;

8. Try to avoid holding the button battery card and negative pole with two fingers for a long time, or short-circuiting the positive and negative poles of the battery with a metal conductor, which will cause short-circuit damage to the battery.

What are the basic structural components of a mobile phone battery holder?

1. Contact

It is the central part of the connector, used to complete the electrical connection function. The contact pair is composed of a positive contact and a negative contact, and the electrical connection is made by plugging the negative and positive contacts together.

(1) The positive contact is a rigid component, which is cylindrical (round pin), square column (square pin) or flat (insert). The positive contact is usually made of brass and phosphor bronze.

(2) The negative contact is the socket, which is the key part of the contact pair. It relies on the elastic structure to deform elastically when plugged into the pin, generating elastic force to form a close contact with the male contact, thereby completing the connection. There are many types of sockets, including cylindrical (slotted, shrinking), tuning fork, cantilever (longitudinal slot), folding (longitudinal slot, 9-shaped), box-type (square socket), and hyperbolic wire spring socket.

2. Insulator

The insulator is also often called a base or insert. Its function is to arrange the contacts according to the required position and spacing to ensure the insulation performance between the contacts and between the contacts and the housing. Good insulation resistance, withstand voltage and processing performance are the basic requirements for selecting insulating materials processed into insulators.

3. Shell

Also known as the shell, it is the outer cover of the adapter. It provides mechanical maintenance for the built-in insulating mounting plate and pins, and provides alignment when the plug and socket are inserted, thereby fixing the adapter to the device.

4. Accessories

Divided into structural accessories and installation accessories. Accessories such as circlips, positioning keys, positioning pins, guide pins, coupling rings, cable clamps, sealing rings, and sealing gaskets. Installation accessories such as screws, nuts, screws, spring rings, etc. Most accessories have standard parts and universal parts.
