Rectangular Connectors - Headers, Male Pins are a type of electrical connector widely used in a variety of applications. The design consists of an interface assembly which mates to a mating header, and uses a set of metal contact pins to make the electrical connections. This article will discuss the application field and working principle of the 640457-2 rectangular connector.

The 640457-2 connector is designed for a variety of applications, including automotive, military, power, IT, renewable energy, robotics and other industrial systems. It is designed for applications ranging from high-frequency, high-current and high-temperature 5G wireless data applications. It is rated at 100 current Amperes (A) and 1000 Volts (V) with a dielectric wihtstanding voltage (DWV) of 1500VAC for one minute. The connector contacts are made of corrosion resistant nickel-plating phosphor bronze and incorporate a floating force of 80—120g per contact.

The 640457-2 connector has two rows of contact pins with a total of nine pins in each row. It has two rows of receptacle connectors. The contacts are arranged in a 2 by 9 array with gaps between them. The two rows form a gap of 1mm between them, enabling the connector to face directly onto flat ribs of the mating connector if required. The contact pins of the mating connector are 0.5mm wide and have a surface mounted to the surrounding base material. The depth of the contact pins is 0.7mm, providing a secure connection.

The receptacle connectors are made of die-cast aluminium alloy and plated with multi-layer electroplating for superior corrosion resistance. They also incorporate a series of apertures and a spring element to ensure positive engagement with the mating connector. The contacts are preloaded to ensure a multi-point contact between the surfaces of the contact and female receptacle. The multiple points of contact provide superior electrical connections to the contact surface areas.

The 640457-2 connector uses a combination of press fit and pull fit connections for secure mating. The press fit connection is designed to provide a means of mechanically securing the connector into the mating connector. The pins are designed to be inserted into a pre-drilled hole in the mating connector, and are secured by pressing down on the contact pins. The pull fit connection is designed to securely hold the connector in place without having to apply any force to the contact pins. It is achieved by using a series of slots that surround the contact pins to create a secure fit between the connector and the mating connectors.

In conclusion, the 640457-2 connector offers a rugged, reliable design for a variety of applications. It offers an economical solution for connection terminations, providing superior electrical contact and multiple points of contact for the individual contact pins. The robust design and preloaded connection ensure an effective and reliable connection for the life of the system. The connector is suitable for use in a variety of applications, from automotive to industrial and power systems. It is also fully compliant with RoHS and CE standards to ensure safe operation in any environment.
