 Model 1-147437-3 is a type of terminal used in PC pin, single post connectors. This type of terminal has become increasingly popular in various industries due to its versatility and reliability. This article will discuss the application field and working principle of model 1-147437-3.

Application Field

Model 1-147437-3 terminal connectors are primarily used in industrial settings, such as in factory assembly lines and production lines. They are also used in automotive, aerospace and medical equipment applications. This type of terminal is designed for reliable, long-term operation and is rugged enough to withstand the rigors of industrial use.

Model 1-147437-3 terminal connectors are often used in applications where space constraints prevent use of larger connectors, such as those found in router or switch boards. They are also used in applications where resistance to vibration, shock or corrosion is required, such as those found in mining equipment or some space applications.

Working Principle

Model 1-147437-3 terminal connectors utilize a cylindrical surface-mount contact with an inner conductor that is crimped onto the conductor being terminated. A spring-loaded pin then forces the outer surface of the contact onto the PCB pad and establishes an electrical connection between the two. The contact is held in place by an insulating jacket.

The contact is designed to provide superior electrical performance, including low contact resistance and superior durability. The contact height is designed to be within the PCB minimum thickness tolerance, which keeps the contact from protruding above the top surface of the PCB. This ensures that the contact is protected from potential damage caused by vibration or shock.

The spring-loaded pin is designed to ensure a long-term, secure connection between the contact and the PCB pad. This pin is compressed when the contact is crimped onto the conductor. The compression of this pin results in a secure connection between the two, and prevents any electrical connection loss due to movement or vibration.

Model 1-147437-3 terminal connectors are durable and reliable, making them ideal for industrial and commercial applications. Their small size and low profile make them suitable for use in space-constrained areas, and their superior electrical performance and secure connection make them suitable for vibration and shock-prone applications.
