Rectangular Connectors - Headers, Receptacles, Female Sockets have been a mainstay of reliable and robust interconnection solutions for over a century. Modern configurations are typically robust due to optimized contact geometry and housings which may include material reinforcements and heatshrinks. The 147738-3 are an example of a popular rectangular connector that offers reliable operation over a large range of industries and applications.

The 147738-3 connector system is of the two-piece variety, consisting of a pair of crimpable female contacts housed in a plastic insulator, and a mating male or female connector. The contacts are made of stainless steel, and together with the thermoplastic insulator and gold plated mating contacts, provide excellent electrical and environmental performance.

The 147738-3 is well suited for many applications due to its simple two-piece construction, small size, and robustness. It is capable of powering up to 5A and can handle up to 500V of power at 500Hz temperatures. Due to its high contact force and resistance to vibrations and shocks, the 147738-3 is commonly used in electric vehicle applications, industrial systems, and networking applications.

Regarding the working principle, the 147738-3 rectangular connectors employ a simple interface with a pair of metal female contacts housed in the plastic insulator and the mating male or female contacts. The female contacts are crimped onto the wires, and the male contacts are then inserted into the insulator. When fully inserted, the contact elements of the connector are in electrical contact with one another, and the contact surfaces are locked in place to maintain connection integrity.

The 147738-3 contacts are designed to ensure reliable connections over time and provide a very low contact resistance. The contact is made from stainless steel, plated with a combination of nickel and gold. This combination ensures low electrical contact resistance and provides protection against corrosion while maintaining a high temperature rating, up to 500V at 500Hz.

The 147738-3\'s two-piece design eliminates the need for an expensive enclosure or jacket. The contacts are crimped onto the leads, which are then inserted into the insulator. This provides a secure connection and simplifies installation. Furthermore, the insulator features a flange, which helps with the alignment of the contacts and provides a robust, tight connection.

The 147738-3 two-piece connector can provide reliable and robust connections in a variety of settings. Its stainless steel contacts, gold plated mating connections, and low contact resistance make it suitable for electric vehicles, industrial applications, and networking. Furthermore, its simple two-piece design simplifies installation and eliminates the need for an expensive housing.
