1-172681-2 Rectangular Connectors - Headers, Male Pins

Introduction

1-172681-2 rectangular connectors are a type of connector commonly used in electrical and electronic applications, specifically in the field of electrical components and appliances. This type of connector is based and derives from the plug-and-socket connectors or headers and male pins. It generally comprises of a female receptacle (or "socket connector") and a corresponding male plug. This type of connector is primarily used to provide a secure and safe connection for signals, power, and data transmission.

Design and Structure

The 1-172681-2 rectangular connectors - headers, male pins, feature a female receptacle which is a rectangular-shaped plastic body. The receptacle has a number of metal pins or male plugs which are held in a plastic housing that is constructed into the female connector. The metal male plugs are typically flattened and consist of a gold-plated metal or brass material with a dimple on one side. The pins are divided into two sets of pins and alternating pin sides are usually provided with a dimple on its head. The metal plug head has a circular groove beneath its head which facilitates the insertion of the plug into the female connector. The female connector has a series of flanges on its body that hold the pins in place while inserting into the housing.

Application Field and Working Principle

The 1-172681-2 rectangular connectors - headers, male pins, are used for a wide range of applications in the field of industrial, automotive, and consumer electronics. It is commonly used in device connection, signal and power distribution, and other wiring applications such as instruments, LED panels, computers, and other electronics. The working principle of 1-172681-2 rectangular connectors revolves around making and maintaining an electrical contact between two or more components in a circuit. This is achieved by inserting the male plug into the correctly sized female connector, and the two are then secured together by screws and/or snap fasteners. This creates an electrical connection between the two components. The electrical current will flow through the pins in the male plug and the female connector to the other components in the circuit.

Benefits and Limitations

The 1-172681-2 rectangular connectors - headers, male pins, offer a number of advantages over other types of connectors. Firstly, the Metal material and gold plated design offers a strong and highly durable connection. Secondly, the pins are arranged to create an efficient connection which reduces the risk of short circuit and offers a secure and safe connection. Thirdly, the female connector can accommodate a range of different plug configurations which is beneficial when connecting multiple devices. However, these connectors are also limited by several factors including their size, pin configuration, and the complexity of the mounting process. Furthermore, they are more expensive in comparison to other types of connectors, such as ribbon or board to board connectors.

Conclusion

The 1-172681-2 rectangular connectors - headers, male pins, is a widely used connector for a wide range of applications in the field of industrial, automotive, and consumer electronics. This type of connector provides a strong and durable connection and offers a secure and safe connection for signals, power, and data transmission. Although there are some limitations to this type of connector, it still remains one of the most preferred connector types for many electronics applications.
