Rectangular Connectors commonly refer to the headers, plug-in receptacles and mating pins used to interface discrete components, printed circuit boards or custom applications. Their simple design and flexibility make them very popular in automobile, apparatus control and communication applications.

Headers of these rectangular connectors fit in a mating receptor or on a PCBwithout soldering. The standard adapted in these connectors is called “Plug & Play” because it allows for quick connections between assemblies. Furthermore, this standard requires insulated housing, a strain relief feature, secure crimp termination and positive lock that give substantial mechanical and electrical protection. These connectors can be crimped or soldered onto conductors.

Male pins are rectangular connectors which can be supplied as part of a female receptacle or housing assembly, ready for mating with a header. They are typically supplied with pins that can be crimped. Having a wide range of lengths, shapes, materials and constructions, male pins offer easy and reliable connections.

Depending on the application and environment, rectangular connectors can be divided into female (multi-port), male (multi-pin),header and plug,airstop and plastic,blade,SPST and SPDT,single-row and double-row,or centered and right-angle. Female connectors are generally applied for power, signal, control, communication,and auto connections while male connectors for insulation,protection,and grounding purposes.

In terms of working principle, rectangular connectors require two mating pieces. Prongs or pins on a male piece fit into holes on a female piece. The spring on the pins creates a secure connection once the two pieces are fit together. A variety of contact arrangements is possible using a variety of pin and socket configurations. The connectors also come in various gauges (thickness and rating of current flow) and can be used for a wide range of current, voltage, and frequency.

Rectangular connectors offer a reliable and robust solution for connecting assemblies that require a durable and secure connection. Their high performance, contact reliability and low cost means that they are suitable for a wide range of applications. From automotive, military, medical, industrial, computer and telecommunications to consumer and much more. They are designed to function reliably in extreme temperature ranges, resist corrosion, withstand mechanical shock and vibration, and provide reliable electrical connectivity.
