Rectangular connectors are electrical connectors used on various types of electrical systems, as well as for a variety of uses, ranging from computer to automotive applications. A particular type of such connector is BCS-145-L-D-HE-074. This type of connector is an industry standard for connectors of this family. It consists of two plastic (or sometimes metal) housings, the header and back-shell, into which contact pins are inserted, allowing for electrical contact between the two housings.

The BCS-145-L-D-HE-074 is known as a “rectangular” connector, since its shape is that of a rectangular, more specifically with a 0.650 inch width x 0.440 inch height. It is a dual housing connector with a locking mechanism to ensure connection integrity, and it has female contacts in the back-shell, allowing for secure signal and power transmission from the back-shell to the header. The application field for this type of connector includes networking, industrial, automation, and automotive electronics.

The working principle of the BCS-145-L-D-HE-074 is relatively simple, yet very efficient. The connector consists of two parts; the header and the back-shell. The header typically contains the pins, while the back-shell contains the receptacles. Upon mating, the pins make contact with the receptacles, creating an electrical connection that is secure and robust. The back-shell also contains two locking clips which ensure that the connection is secure and tamper proof.

In order to ensure robust and reliable transmissions, special features are built into the connector, such as insulation displacement contacts (IDC) and split-beam contacts. In the case of IDC, instead of the traditional insertion of wire into the back-shell, the contacts are instead occupied by a flat ribbon cable, and when secure, the cable cuts through a special insulation material built in the contact and creates a secure electrical connection. The split-beam contacts of the BCS-145-L-D-HE-074 consist of a two layers metal contact with an upper split and lower flat part, allowing for improved mating forces and retention, as well as reduced mating and unmating volume.

As mentioned before, this type of connector is used in many fields, including networking, industrial, automation, and automotive electronics. It is particularly suitable for applications where space is a real constraint. For example, the connectors can be useful for Ethernet connections in electronic boards, as the typical size constraints and demanding mating system allow for a secure connection without taking up much space on the board. In industrial applications, they can be used in order to allow for quick and reliable connections between motors and controllers, for example, reducing the installation and response times of machines. In automative applications, they are used for diagnostics. The split-beam contacts provide for improved connections that are both easy to install and reliable. Finally, they also have applications in the medical field, for example in connection between imaging tools and patient electrodes.

To sum up, the BCS-145-L-D-HE-074 is a particularly useful rectangular connectors due to its small size and secure locking mechanism which allow for tight connections in space constrained applications. It has a variety of uses in industries such as networking, industrial, automation, and automotive electronics, as well as in the medical field. Its working principle consists of the insertion of pins into the back-shell which make contact with the receptacles, while special features such as split-beam contacts ensure improved mating forces and retention.
