What do I need to know about using female connectors?

The female connector is one of the many connectors that are often used as a connection on PCB boards for electronic products. When using different PCB boards, they should be selected according to the corresponding requirements of the electronic products and equipment. Generally speaking, size and the available space of the electronic device are the key points to consider, because generally speaking, the smaller the size, the smaller the contact spacing and the higher the contact density. Such a tight contact design generally means less insulation and lower forces.

I. The use of female connectors need to know what is the knowledge of 1, the first thing to consider when purchasing is the purchase is able to meet the voltage and current requirements of the electronic PCB board, to know the connector products are used for low-level circuits or power supply circuits. Because there is no current can not work, so the purchase should choose the contact plating is not easy to oxidize, because it can not penetrate the oxide layer in the conditions of small current, low voltage. 2, the general business in the production of electronic products need to purchase the mother of the connector, it is recommended to select the high temperature resistance, because the electronic products in the process of using the working temperature. If you choose high temperature resistant in the production of electronic products, you can reduce the adverse effects in high temperature conditions. If the use of non-high-temperature resistant connectors, in the operating temperature is too high will not be able to withstand, may cause the connector or electronic PCB board burned, affecting the use of electronic products. 3, if the production of electronic equipment products used in the use of fewer insertion and extraction, you can consider low-cost ordinary contacts. Because the contact pressure is an important indicator of the connector, if the contact pressure is larger, it means a larger insertion force and pull-out force, which directly affects the contact resistance and wear and tear of the contact parts. 4, do not frequently unplug and insert the connector that has been fixed to the PCB board of the row of female connectors, because if the connector terminals and other components are worn to a certain degree, when this wear and tear to reach a certain wear-resistant value, the mechanical life will be reduced This will affect the service life of the connector. Do not insert diagonally when used on electronic equipment, as this may cause the pin connection of the female connector to not be fully connected to the electronic equipment, and other connections or lines on the electronic equipment should not be inserted or removed at will. Otherwise, it may lead to some data abnormality or connection loss when using.
