• Several ways to connect PCB terminal blocks

  Aug 20, 2024

  1. Screw connection: This method uses screw terminals to connect wires. It is important to consider the maximum and minimum wire cross-sections allowed, as well as the maximum torque for different screw sizes.2. Soldering connection: The most common soldering method is tin soldering. It is essential to ensure that a continuous metal connection is formed between the solder material and the surface being soldered. Different types of soldering connections include solder tab style, eyelet solder tab style, and arc notch solder tab style.3. Crimp connection: Crimping is a technique where metal is compressed and displaced within specified limits to connect wires to contact pairs. Good crimp connections can produce metal intermolecular flow, resulting in symmetrical deformation of the wire and contact material. This type of connection is similar to cold welding and can withstand harsh environmental conditions.4. Wrapping connection: Wrapping involves wrapping the wire directly around the angular contact pillar. The wire is wrapped, pressed, and fixed at the angular contact pillar to create a sealed contact.

• When using PCB terminal blocks for wiring applications, it is important to keep in mind the following precautions.

  When using PCB terminal blocks for wiring applications, it is important to keep in mind the following precautions:1. Always ensure that the power is switched off before starting any wiring operations. Never attempt to work on the terminal blocks while they are live. If you are unsure whether the power is off, use a voltage tester to verify. Additionally, if there are sliding buttons on the terminal blocks or switches, it is advisable to replace them if they are worn out to prevent any risk of electric shock.2. When connecting to the power source, make sure to install PVC conduit for wire routing. Avoid leaving wires hanging loosely without any proper support or fixation on support brackets or busbars.3. Pay attention to the length of the wires when connecting to the switch box. It is recommended to keep the wire lengths within a suitable range and properly route them through conduits. Avoid pushing the wires directly into the switches for fixing.By following these precautions, you can ensure safe and efficient operation of the PCB terminal blocks. If you have any further questions or need assistance, please feel free to contact us.

• What is PCB terminal block?

  Jul 01, 2024

  PCB terminal block refer to electrical connection devices for connecting on printed circuit boards (PCBs). They provide a reliable and convenient way to connect and disconnect circuits, and are usually used to fix wires or connect plugs, sockets and other devices.   There are many types of PCB terminals, the most common of which include:   1. Pluggable terminal block:The Pluggable PCB Terminal Blocks are available in different configurations to suit your specific needs. The main types include male parts and female parts, with standard pin spacings of 2.5mm, 3.5mm, 3.81mm, 5.0mm, 5.08mm, 7.5mm, and 7.62mm. Homnecks provide flexibility for various design requirements and compatibility with different systems.   2.Screw terminal block: a convenient and efficient solution for your PCB assembly needs. Our Screw Terminal Block can be directly soldered onto your PCB board, allowing for easy and secure wire connections. The screw terminals provide a reliable and secure connection that can easily be loosened or tightened for quick and convenient wire adjustments.   3. Barrier  terminal block: PCB Barrier Terminal Block, designed for high-performance controller products that require superior electrical properties. Featuring a plastic material made of flame-retardant PA66 and tin-plated copper metal components, our Barrier Terminal Block offers excellent electrical performance. This makes it ideal for applications where high current and voltage requirements are a priority. 4.Spring Terminal: Spring terminals use spring mechanisms to achieve circuit connection by clamping wires or terminal pins. This type of terminal usually has the characteristics of quick connection and disconnection, which is convenient for maintenance and replacement.   Our terminal blocks are manufactured with high-quality materials to ensure reliable performance and durability. They are designed for easy installation and maintenance, making them ideal for a wide range of industrial and commercial applications.
