Rectangular Connectors – Arrays, Edge Type, Mezzanine (Board to Board)Rectangular connectors (0459703187) and their various array and edge types, also referred to as mezzanine board to board connectors, are being widely used in the electrical, electronic, and industrial control industries both for providing terminals and interconnects, protecting against fault conditions, and helping to maintain reliable, low-cost signal connections. Connectors can be relatively simple, one-piece construction or quite complex requiring multiple parts and tools to install.An individual rectangular connector is made up of two sides, a housing and a receptacle, each with one or more contacts which mate to establish a connection. Rectangular connectors come in various shapes and sizes, with specialized types for specific applications such as edge card connectors, flat ribbon cable connectors, and specialized hermaphroditic applications. Edge type connectors provide terminals along the end of the assembly, while array connections provide terminals along the length, allowing more than one connection in a single row or along an edge.The primary components that make up a rectangular connector are a housing and a receptacle, along with contacts, leads, strain relief, and a grounding fingers or star tongue. Each of these components functions to provide a reliable, low-cost connection. The housing provides environmental protection and support for the contacts, while the receptacle provides signal pathways and retention to maintain contact alignment and makes connection easier for the installer. The contacts provide signal and power connections, and the leads, strain relief, and grounding fingers or star tongue perform supporting functions, such as providing reliable grounds and reducing weight and cost.Connectors size and design can be tailored to meet specific customer requirements. Design changes can be as simple as adjusting contact spacing or size, adding or removing shielding, or adding additional components for special functions such as filtering, current sensing, or bus wiring. An example of a popular rectangular connector is the Molex Series mate-connect, which features special strain reliefs and a special grounding feature to provide an enhanced connection. It also has multiple connector types available to meet different specific needs, such as line cards, lower power applications, and high speed environments.When selecting a rectangular connector, there are several factors that should be considered. Orientation, pin and contact spacing, material, and the shape and size are all important, as each factor can affect the ability of the connector to perform in the environment in which it is used. Additionally, the type of connector should be chosen according to the application. Edge Card type connectors are typically used for low-profile applications, while Arrays can be used for larger, higher-profile applications such as backplanes or panel components.Rectangular connectors provide a cost effective solution for making reliable, low-cost connections, and are used in countless applications across many industries. Knowing the advantages and disadvantages of the various types of connectors, and the factors to consider when selecting a specific connector, will help to ensure that the ideal solution is found for the application.
