Many people ask, "What kind of connector does a battery need? Can't you just press it into the slot? Why is there a special battery connector?" In the following short series, we will explain the structure and some knowledge about battery connectors:

The basic structure of a battery connector includes: ① contact elements, ② insulator, ③ housing, and ④ accessories

1. The contact point is the core of a connector that performs the function of electrical connection. The contact pair generally consists of a positive contact piece and a negative contact piece.

The positive contact part is a rigid part, shaped as a cylinder (round pin), square column (square pin), or flat (insert). The positive contact point is usually made of brass and phosphor bronze.

The negative contact part, a key component of the contact pair, is the jack. When inserting the pin, elastic deformation relies on the elastic structure, and the elastic force comes into close contact with the positive contact part to complete the connection. The structural forms of jacks include pillars (grooves, constrictions), tuning forks, cantilever beams (longitudinal grooves), folds (longitudinal grooves), boxes (square jacks), and double-curved spring jacks, etc.

2. Insulators are also commonly referred to as substrates or plugboards. Their function is to arrange contact elements according to the required position and space, ensuring insulation performance between the contact elements and the housing. Good insulation resistance, voltage resistance, and workability are the basic requirements for selecting insulating materials to be processed into insulators.

3. The shell, also known as the housing, is the outer cover of the connector, providing mechanical protection for the built-in insulating mounting plate and lock. It also performs alignment when the plug and socket are inserted to secure the connector to the device.

4. Accessories are divided into structural accessories and installation accessories. Structural accessories include clamping rings, locating keys, locating pins, guide pins, connecting rings, cable clamps, sealing rings, gaskets, etc. Installation accessories such as screws, nuts, bolts, spring coils, etc., mostly include standard parts and common parts.
