Connectors Used With Electronics Boards
When it comes to building and maintaining electronic devices, the type of connector you choose plays an important role in determining the device’s reliability, performance, and cost. The right connector can ensure that current-carrying components are properly insulated, and it can also prevent damage from shock, moisture, or corrosion. As such, the choice of a connector is an important decision to be made by the device’s designer or engineer.
Among the many different types of connectors, some stand out for their unique features. For example, some are designed with a locking mechanism that secures the connector to its mating component, ensuring a steadfast and durable connection. Others are crafted with polarization or keying features, which prevent incorrect insertion and ensure that the connector is connected in the correct orientation. The type of material used for the connector’s housing can also affect its durability and resistance to environmental factors, such as temperature and humidity.
The most common type of connector in use today is the USB connector, which can be found in almost all electronic devices. The USB connector features four contact points: one receives power, and the other two transmit and receive data. These contacts are used to communicate between the motherboard and other parts of the system, such as a USB hub or external hard drive. Other types of connectors that are commonly used with electronics board include DB15 (for VGA), DB25 (for SATA), and DB37 (for DVI).

Aside from providing an electrical connection, PCB connectors can also provide mechanical stability. This is especially important in environments where the connector must withstand vibration and other environmental factors. To achieve this, the connector is typically constructed from a material that is both flexible and durable. The best materials for this purpose are plastics and metals. Plastics are preferred for their flexibility, while metals are often chosen for their durability and strength. New materials are also being introduced to the manufacturing process for improved performance and durability.
Other important characteristics of a connector are its termination method and lock mechanisms. For instance, some are designed with screw terminals that provide a firm connection to the pin header while allowing for easy wire insertion and removal. Other connectors are characterized by their crimp-style connections, which involve crimping a contact onto the end of a wire and inserting it into a terminal block that mates with the connector on the PCB. This type of connector is often used with ribbon cables, and it provides a quick and reliable connection in a wide variety of applications.
Other types of connectors include card edge connectors, which offer high-speed connections between a motherboard and expansion cards such as graphics cards and RAM modules. They are typically used for desktop and laptop computers. RJ11 connectors are another popular type of connector, which allow for telephone line connections to devices like phones, modems, and fax machines. These connectors have 2 to 6 contacts and are designed with a symmetrical shape that ensures proper insertion. Finally, Ethernet connectors, which are used to connect networks and other devices, feature 8 contacts and are a standard feature on most modern motherboards.
