What is the installation method for the button cell battery holder?

What are the installation methods for a coin cell battery holder?

A coin cell battery holder is used to hold coin cell batteries. It is usually soldered onto a PCB to facilitate the supply of coin cell batteries to modules such as clocks or other consumer electronics. So, what are the installation methods for a coin cell battery holder?

What are the installation methods for a coin cell battery holder?

There are two installation methods for coin cell battery holders: insertion and surface mount.

What are some suggestions for selecting a coin cell battery holder?

1. Installation efficiency;

2. Accuracy and suspension;

3. Coin cell battery space occupancy. In many miniature instruments, coin cell batteries are key components;

4. Cost of the coin cell battery holder. Common plastic materials include LCP, PPS, and PBT, while common metal leaf materials include iron, steel, and copper (metal leaf plating treatments such as nickel, tin, and gold). Different materials vary in terms of temperature resistance, corrosion resistance, drop resistance, conductive stability, and refined appearance.

5. If PCB space is a concern, battery clips (pure hardware) can be chosen, but the positive and negative poles of the battery clip are separate components, adding an assembly step. For example, for a separate remote control, choose a positive battery clip and a negative battery clip, or use gold, nickel, or tin deposition processes.

What are some common problems with coin cell battery holders?

1. How to identify the positive and negative poles of a coin cell battery:

Usually, the coin cell battery marked with a "+" is the positive pole, and the back is the negative pole; the outer casing at the edge of the coin cell battery is also the positive pole, so most of the coin cell batteries in the coin cell battery pack are facing upwards, because the side end of the coin cell battery pack has a metal leaf to prevent the coin cell battery from falling out. This is the positive metal leaf, which will adhere tightly to the positive edge of the coin cell battery. Due to the large-area electrode contact of the positive metal leaf, the stability of the electrode contact is effectively improved. If the positive and negative poles of the coin cell battery are reversed, the battery can be jammed, but the battery will short circuit.

2. How to remove the battery from the coin cell battery holder:

Products with coin cell battery holders facilitate the replacement of old and new coin cell batteries, and the metal leaf can be easily moved. After careful searching, you can find a way to remove the coin cell battery. Some coin cell battery holder designs may require a small insulating plastic piece to help remove the coin cell battery.

3. Coin cell battery holders cannot be soldered with tin:

(1) Add solder paste to reduce surface tension and improve wettability;

(2) Increase the soldering temperature;

(3) Change the solder paste.

What are the functions of a battery holder and a lamp holder?

A battery holder is a box designed to provide the voltage required for the power supply of an appliance, and a lamp holder is connected to cooperate with the lighting of the lamp. If the alarm has five wires, the other three wires are connected to the three anti-theft wires on the controller. The red wire is the positive pole, the black wire is the negative pole, and the blue wire is connected to the door lock.
