D-Sub connectors, such as the 4-745130-1, feature flat-shaped contact points arranged in a row, known as pins, which connect two components or edges in an electrical circuit. Accessories associated with this type of connector include backshells, nuts, washers, clamps and strain relief devices. The contact points in this connector are arranged in dual rows and can support up to 9 contact terminations in one connector. Female connectors have sockets that allow the pins of the male connector to be inserted, forming an electrical connection. These connectors are popular in computer applications, such as the connection of a printer to a laptop, as they offer a strong, stable connection and low contact resistance.The contact points of the 4-745130-1 connector feature a d-shaped form and can handle both serial and parallel communications. This type of contact has excellent contact transmission capacity as it enables significant resistance to electrical and mechanical stress and has superior breakage. These features all make it an ideal choice for extending and connecting the output of a printer or any other electronic device.These connectors typically feature a pre-assembled mate/unmate force, which when connected, ensures reliable contact force for high-frequency applications. The contact forces are protected by an anti-pullback design which prevents the mating contacts from unwanted disconnections due to external forces or shocks. In addition, the pre-assembled mating and unmating force also minimizes the overall mated cycle times, offering reliable performance even in high-vibration and shock scenarios.The contact material used for the 4-745130-1 connector is usually copper-alloy, with gold plating or silver plating available for preventing oxidation or corrosion in environments where moisture is present. The pin insulator is typically constructed of a dielectric material and is designed to prevent pin-to-pin contact, which would create a short circuit.The 4-745130-1 connector has a variety of applications due to its robust design and contact transmission capacity. It is appropriate for a range of industries, including medical, telecommunications, aviation and automotive. The connector has the ability to be used both indoors and outdoors, making it a versatile choice for many applications.In terms of its working principle, the 4-745130-1 connector facilitates an electrical connection using contact insertion and retention. The contact pins located on the connector, which are also referred to as tongue pieces, are inserted into the socket on the female connector. This causes the contacts to become engaged with each other and form an electrical connection, which is the basis of the connector’s functioning.To further protect the contact pins from physical and electrical damage, a strain relief device can be used. This works by reducing mechanical stress on the contacts, something which can be caused by expansions and contractions in the connecting wires due to temperature changes. The use of a strain relief device ensures that the contacts remain firmly engaged for the duration of the connection.Overall, the 4-745130-1 D-Sub connector is a versatile and reliable connector. Featuring protection against mechanical and electrical damage, as well as a low contact resistance, the connector is suitable for a range of applications in the medical, automotive, aviation and telecommunication industries.
