Besides pin design, there are other types of connector plugs. For example, some connector plugs are designed with round or square contact pads, which can provide larger contact area and better electrical connection. Some connector plugs are designed with slots or contacts for connecting wire harnesses or circuit boards. In addition, connector plugs can have different lead numbers and layouts to meet specific application requirements.
Therefore, the connector plug is not necessarily a pin, and many different designs and forms can be adopted, which can be selected according to specific application occasions.
