Rectangular Connectors - Housings

Rectangular connectors, also known as D-subs, perform a vital role in linking satellite connections in computing, avionics, telecommunications, and other industrial engineering applications. A rectangular connector typically consists of a connector housing, which provides a receptacle for housing a connector insert and holds the contacts captive, and a mating connector insert that provides termination points for a cable assembly or an insulated wire. 0874390800 is a rectangular connector housing that is commonly used in many engineering and industrial applications.

Description

The 0874390800 connector housing is a four-position rectangular connecting housing with a polarization feature. It features two equally spaced insertion sides, dimensions of 2.81 ” x 0.80 ”, and a thermoplastic resin body. When mated, its internal contacts secure firmly, and avoid looseness, loosening, and scratching. In addition, mating is aided by an offset of its contact sections of 5.00mm, making it easier to insert. The 0874390800 connector housing is available for use in a wide range of cable sizes, including 0.37mm² to 1.5mm², and wire sizes of 18 to 28 AWG.

Application Fields

The 0874390800 is ideal for use in various environments, including in computer and telecommunications applications. The housing is more often than not paired with an 0874390801 insert, which is designed to mate with components such as the 0874390805. This resilient and non-captive contact provides a secure connection with minimal space requirements. It is typically used with cable applications, such as in electronic assemblies and computers, but is also suitable for a wider range of uses, like avionics.

Working Principle

The 0874390800 is designed with a thermoplastic resin body that ensures durability and mechanical strength throughout its lifetime. Its precision-mounted contacts, which are protected with a protective cap, ensure secure and reliable mating. When mated, the holder secures the contacts, and prevents electrical arcing, looseness, or other instances of looseness. Furthermore, the connector’s metal jack screws are used to ensure secure mechanical retention to the mating components. The screw length typically ranges between 1.5 inches to 3 inches. It also features contacts that are designed to give reliable crimp termination.

Conclusion

The 0874390800 is a rectangular connector housing designed for a wide variety of applications. Its features such as the thermoplastic resin body, precision mounted contacts, and the metal jack screws making it reliable and secure. The connector housing is typically used with the 0874390801 insert, and is suitable for a variety of environments in industrial or engineering applications. Additionally, its contacts provide reliable crimp termination which ensures that electrical arcing and looseness are avoided when mated.
