Rectangular Connectors – Headers, Male Pins are used for a variety of applications. The application field covers airframes, computing and communication applications, automotive, industrial, and medical equipment. This article will focus on the 178303-2 connectors in depth, discussing their application field, as well as how they work and their advantages.

Application Field: The 178303-2 is a receptacle type connector used for terminating flat cable assemblies. It is designed for high reliability mechanical connection with easy, secure solder-less terminations and contact retention. It offers the highest degree of contact continuity and contact retention common in the industry. It has 12 positions, 5.08mm pitch, and 2.54mm spacing.

Typical applications include cell phone and base station, wireless communications, computers, router and modem equipment, and network systems. It is most commonly used in the communication and industrial control market due to its reliable connections and secure terminations.

Working Principle: The 178303-2 connectors use contact-locking technology that ensures a secure connection, provides a self-cleaning contact surfaces, and will consistently provide a highly reliable connection over time. The contact technology has two sets of contact pins that are engaged when the connector is inserted into the mating receptacle. The first set of contacts is used to lock the connector in the mating receptacle while the second set of contacts provides an electrical connection.

The mechanism works by a spring metal contact pushing against the yellow contact locator in the middle of the connector. This contact then pushes the female pin in the mating receptacle, resulting in a positive connection. The contact locator also ensures that the connector will not disengage from the mating receptacle, even when subjected to mechanical vibration.

Advantages: The 178303-2 connectors have several advantages over mechanical connectors. They are much more reliable due to the contact-locking mechanism, and have a longer lifespan than mechanical connectors. They also offer faster installation time and higher mating force, as well as a higher degree of contact retention. Finally, the 178303-2 connectors have a much smaller size than mechanical connectors, making them a great option for space-constrained applications.

Overall, the 178303-2 connectors offer excellent performance in terms of their application field, working principle, and advantages. They provide a reliable and secure connection, which is especially important in the communication and industrial control markets. These connectors are highly durable and offer superior contact retention, making them a great choice for many applications.
