What are battery holder connectors? What are the main types and what are their characteristics?

A battery holder connector is a connector used to connect a battery to an electronic device. It is usually designed as a snap-on connector to ensure that the battery is securely fastened inside the electronic device and easy to replace. There are more types of battery holder connectors, including pin header, snap type, spring type, etc. Below we will introduce the characteristics of each of them. Pin Header A pin header is a connector that connects a battery to an electronic device via pins. It consists of multiple metal pins which can be inserted into the positive and negative terminals of the battery and secured to the seat of the electronic device. Header connectors typically have good electrical performance because the pins make good contact with the battery and have low resistance. However, header connectors are more difficult to maintain because the pins need to be aligned when connecting, and if the pins are bent or damaged, the entire connector needs to be replaced. Snap-on Snap-on connectors are easy-to-use connectors that connect a battery to an electronic device via a snap mechanism. Snap connectors usually have good electrical and mechanical properties, and have a reliable fixing function to ensure that the battery will not fall off in use. However, snap type connectors usually take up a large amount of space, so their size needs to be taken into account when designing them. Spring-loaded Spring-loaded connector is a connector that connects a battery to an electronic device by means of a spring. It consists of one or more springs that can be inserted into the positive and negative terminals of the battery and secured to the seat of the electronic device. Spring-loaded connectors typically have good mechanical properties, can accommodate different battery sizes, and are easy to replace. However, spring-loaded connectors can have poor electrical performance because the springs do not contact the battery as closely as the pins, resulting in higher resistance. Other than the common battery holder connectors mentioned above, there are some other types of connectors, such as SMT patch type and copper chip type. These connectors are usually used for small batteries or occasions that require soldering on PCB boards, and have the advantages of small size and easy installation.
