1967-1

Since 1967, terminals and connectors have become an integral part of our daily lives. But how did these components originate, what were their applications in the industry, and how did they work? Here, we will discuss the applications and workings of one type of terminal from 1967; PC pins, single post connectors.

One of the oldest uses for these connectors was in the cable network systems. In these systems, cables were connected to the surface of the connector in order for them to carry signals between components. This allowed for the use of multiple components, such as computer network cards, which could communicate with each other through the use of PC pins. The current ratings for these connectors in 1967 was 3A, meaning they were capable of handling higher amperage than many of the competing connections at the time.

In addition to cable network systems, these connectors were used in telephone and other communication lines. They were robust and allowed for quick installation of communication lines such as PBX lines and computer data lines. With the addition of identifying nozzles and strain reliefs, these connectors were used for a variety of applications including industrial control systems, automation, and motor control systems. This allowed engineers to quickly install these lines in complex applications without worrying about the connector’s integrity.

Regarding the working principle, a metal pin was inserted into a square sleeve and held in place by a latch and locking mechanism. The pin was then connected to the other components by a wire or ribbon. This was a reliable and secure electrical connection. As mentioned previously, the current rating for these connectors was 3A. This ensured that the pins could handle higher voltage and current than many of the alternative connectors.

To conclude, PC pins, single post connectors, were popular from 1967 onwards. They were typically used in cable network systems, telephone and communication lines, and industrial control systems. As far as their working principle, it is a simple metal pin inserted into a square sleeve and held in place by a latch and locking mechanism. The current rating for them is 3A which made these connectors even more popular.
