Basic knowledge of connectors

Connectors are used to connect the sub parts of a circuit together. Usually, when using connectors, it may be necessary to disconnect the sub parts under specific circumstances, such as power input and output. The disconnection and connection with the circuit board, the insertion of headphones, and so on are all considered connectors.

Connector Gender

Gender - The gender of a connector refers to whether it is inserted or not, and is usually "male" or "female" (child, please seek a more comprehensive explanation from your parents). Unfortunately, in some cases, connectors may appear as' female 'but may be referred to as' male'.

Polarity

Polarity - Most connectors can only be connected in one direction. This characteristic is called polarity, and connectors with devices to prevent them from connecting incorrectly are called polarized.

contact

Contact point - The contact point is the business part of the connector. They are metal components that come into contact with each other, forming an electrical connection. This is also a problem prone area: the contacts may become dirty or oxidized, or the elastic force that presses the contacts together may dissipate over time.

spacing

Spacing - Many connectors consist of a repetitive pattern of contact arrays. The distance between connectors is the distance from the center of one contact to the center of the next contact. This is important because there are many contact series that look very similar, but their heights may vary, making it difficult to know if your purchased connector can pair properly. By purchasing connectors with the same spacing, these troubles can be avoided.
