The H3151 are a series of high-quality self-locked PC pin connectors. They are also known as single- post terminal blocks with high-contact reliability. The PC pins are housed in a bright white-injected dielectric body. This construction of the terminal blocks ensures that it provides superior electrical insulation and an optimum connection between the mating members. The self-locking mechanism of the terminal blocks prevents any accidental unplugging of the wires.

The primary application of the H3151 terminal blocks is for connecting various components on various printed circuit boards (PCB). Depending on the application, the H3151 connectors are available in a variety of pole sizes ranging from 2 up to 10. Additionally, the contact spacing of the terminal blocks ranges from 5 to 8.25 mm. This makes them suitable for applications of different board sizes. Furthermore, the terminals are available in combination with long pins for a good, secure connection.

The terminals are made of nickel-plated brass contacts which provide durability and low contact resistance. The terminals’ contact surfaces also feature an anti-corrosion coating that ensures that no moisture can build up and cause short circuits. Additionally, the terminals are designed to withstand high vibration and shock, and they include a strain relief for extra durability.

The working principle of the H3151 PC pin connectors is quite simple. The terminal blocks feature a “push - to-connect” system in which the user inserts the wire into the contact holes and pushes the lever or knob to lock it in place. The terminals also come with self-locking mechanisms which prevent accidental unplugging of the wires by locking them in place once they are inserted.

Furthermore, the H3151 terminal blocks also come with a safe disconnect system, which disconnects the power when the terminal blocks are unlocked. This ensures that the equipment is not damaged by power surges or power outages. Additionally, the terminals include labeling to ensure clear identification of all the connections, even when there are a large number of them.

Overall, the H3151 PC pin connectors are a reliable and durable option for connecting various components on PCBs. Their self-locking and safe disconnect systems offer secure and dependable connections, and their anti-corrosion coating prevents the possibility of short circuits due to moisture accumulation. Furthermore, the terminals offer good contact reliability and are capable of working in high vibration and shock environments.
