Introduction:
691121710004 Terminal Blocks - Wire to Board are widely used in electronic and electrical circuits. These blocks provide a stable and secure connection between two wires or cables. They are manufactured for use in high-power and difficult environments, and they provide a reliable connection between components for long term operation. They also offer protection against moisture and vibration, electrical noise, hot or cold extremes, shocks, and mechanical damage.

Application Field:
Terminal blocks are used in many different applications, both in residential and commercial environments. They are used to maintain electrical and electronic circuits, which include power, control, and instrumentation circuits. In residential environments, these blocks are typically used in power supply circuits, residential audio-visual systems, medical and scientific equipment, security systems, solar panels, and motor control circuits. In commercial applications, they are often used in power supply circuits such as central air conditioners, elevators, escalators, and industrial installations. Additionally, they are commonly used in military applications, some medical equipment, aerospace, automotive, and computer components.

Working Principle:
The working principle of 691121710004 Terminal Blocks - Wire to Board is simple but effective. Basically, they are used to create a secure and reliable connection between two electrical pieces. The two wires to be connected are inserted into holes along the opposite edges of each block. Once the wires are inserted, a screw is tightened to create a reliable secure connection. Depending on the type of application the blocks may be insulated with a specific type of insulation material to prevent electrical shorts. The shape of the terminal block also helps to resist vibration and temperature changes, although it is the insulation that provides the most protection.

Plugs and Wire Strips:
691121710004 Terminal Blocks - Wire to Board also come with plugs and wire strips that can be used to make the connection complete. The plugs are used to connect the terminals together. The wires are then inserted through the holes in the plugs and connected to the terminals. Wire strips can also be used to make it easier to connect the two wires. The wire strip is inserted into one of the blocks and the wire is then soldered to the terminals. The wire strips help to reduce the risk of stripping or melting the insulation on the wires.

Steady Performance:
One of the greatest advantages of using 691121710004 Terminal Blocks - Wire to Board is their steady performance over time. When subjected to long-term, high-power utilization, the blocks will remain in place without significant wear and tear. In addition, the insulation on these blocks is designed to withstand temperature extremes, shocks, and mechanical damage without breaking or degrading. This makes them an excellent choice for applications that require a secure, reliable, long-term connection.

Conclusion:
691121710004 Terminal Blocks - Wire to Board are a common component of many electronic and electrical systems. They provide a secure, reliableconnection between two wires or cables, and they are manufactured for use in high-power and difficult environments. Their steady performance over time and protection against temperature extremes, shocks, and mechanical damage make them an ideal choice for many applications. Additionally, their use of plugs, wire strips, and insulation further enhances their reliability and performance.
