Rectangular Connectors - Headers, Receptacles, Female Sockets are one of the most common types of connectors in the electronics industry today and their use spans across a variety of application fields. The working principle of a rectangular connector involves a set of eight or more parallel gold-plated contacts, with up to 16 pins in a 0.100-inch grid pattern. The two pieces of the connector, the header and the receptacle, are held together with a retainer, a detent, or a spring clip. The header and receptacle are spray-painted with an insulating material and the contacts feature a solder cup that is secured around the pins inside the connector.

Rectangular Connectors are most commonly used in high-density applications where the connecter\'s small housing is an essential requirement. Common application fields include computers, industrial controls, audio-visual equipment, telecommunications equipment, and robotics. The working principle of a Rectangular Connectors involves taking advantage of a very simple, yet effective method of assembly and interconnection - by connecting two parallel rows of pins, using an interference fit between the two halves.

The key feature of a rectangular connector is its ability to provide multiple contacts in a very compact space. This allows for connections to be made with multiple traces, as well as with multiple contacts. In addition, when a connector is mated, there is no electrical contact between the header and receptacle. This prevents any potential problems caused by over-mating two connectors, which could lead to an electrical short circuit.

When a rectangular connector is used, the header is placed on one side of the board and the receptacle is placed on the other side. The contacts are then soldered into place. After the solder has cooled, the finished assembly is then loaded onto the board. The interference fit between the header and receptacle helps ensure secure connection of both components and prevents any accidental disconnection.

The header and receptacle of a Rectangular Connectors are usually manufactured from copper or brass. Each contact is a soldered cup, with its pins pointed inward. The contacts are then sprayed with an insulating material and the insulation is then secured with a retaining clip or detent. The clips or detents are designed to ensure that the header and receptacle stay connected.

Each pin inside the Rectangular Connectors is typically gold plated and offers a very low resistivity, ensuring that the electrical connections remain strong. The receptacles also include a spring-loaded clip, which keeps the contacts connected. This ensures that the connection remains secure even when the two parts of the connector are moved or bent.

In short, Rectangular Connectors are one of the most important components in the electronics industry today. Their applications span across many different fields and have become indispensable. Their working principle is simple yet effective, and the ability to provide multiple contacts in a compact space makes them essential elements in any design.
