What are the precautions for button cell holders?

Button cell batteries are widely used in various delicate components. Everyone is certainly familiar with the use of button cell batteries; they are frequently seen in daily life. In fact, these are all benefits brought about by technological advancements, allowing such small batteries to play such a significant role. Speaking of button cell batteries, we must mention battery holders issues, battery holders play a very important role in button cell batteries; many people simply call them button battery holders . So, what are the precautions for button cell holders?

What are the precautions for button cell holders?

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

2. Because the types of materials used in button cell batteries are different, they should be determined according to the electronic product;

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

4. Do not use a soldering iron to solder leads onto the battery;

5. Do not throw used batteries into a fire, as this will increase the battery temperature and cause the battery to burst;

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

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

8. Try to avoid holding the button cell battery's tab and negative electrode with two fingers for a long time, or short-circuiting the positive and negative electrodes of the battery with a metal conductor, which will cause the battery to short-circuit and damage.

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

1. Contact

is the central part of the connector, used to complete the electrical connection function. It consists of a positive contact and a negative contact to form a contact pair, and electrical connection is achieved through the insertion of the negative and positive contacts.

(1) The positive contact is a rigid component, and its shape is cylindrical (circular pin), square columnar (square pin), or flat (insert). Positive contacts are usually made of brass and phosphor bronze.

(2) The negative contact, or socket, is a key part of the contact pair. It relies on an elastic structure to elastically deform when mating with the pin, generating elasticity to form a tight contact with the male contact, thus completing the connection. There are many types of sockets: cylindrical (slotted, crimped), tuning fork, cantilever (longitudinally slotted), folding (longitudinally slotted, figure 9), box-type (square socket), and double-curved wire spring sockets.

2. Insulator

Insulators are also often called bases or inserts. Their function is to arrange the contacts at the required positions and spacing, ensuring 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. Housing

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

4. Accessories

Divided into structural accessories and mounting accessories. Retaining rings, locating keys, locating pins, guide pins, connecting rings, cable clamps, sealing rings, sealing gaskets, etc. Mounting accessories, such as screws, nuts, bolts, and spring rings. Most accessories have standard parts and general-purpose parts.
