General knowledge of round hole busbar connectors
Next for us to introduce some common sense about circular hole exhaust, hope to help us.
Round hole Pin and stem adapter, English name: Pin Header. This connector is widely used in electronics, electrical appliances, PCB board in the appearance, its role is in the circuit is blocked or isolated between the circuit, play the role of bridge, take on the mission of current or signal transmission. Generally, it is used together with the row bus to form a plate-to-plate connection; Or it can be used together with the electronic wire harness terminal to form the connection of plate-to-wire; It can also be used independently for board to board connection.
Because the specifications required by different products are not the same, there are also various types of specifications for needle arrangement, which are classified according to the specifications for electronic professional needle arrangement connectors:
