II. Screw Terminal Blocks: Characteristics
Screw terminal blocks secure wires using screws, resulting in a robust structure. They are one of the most common types of terminals in industrial applications.
Main Features:
- Secure wire fixation with strong tensile strength
- Suitable for medium to high current applications
- Low cost and high versatility
- Available in various configurations, including PCB mount screw terminals, 2-pin, 3-pole, etc.
III. Spring/Screwless Terminal Blocks
Spring terminal blocks use spring clips to secure wires, eliminating the need for screws and improving assembly efficiency.
Key Advantages:
- Fast wiring, reducing labor time
- Excellent vibration resistance
- Suitable for high-density PCB designs
IV. PCB Mounting Terminals and Barrier Terminal Blocks
In applications requiring high insulation distance and safety, barrier terminal blocks are widely used,
suitable for power supplies, power control, and industrial equipment.
V. How to Choose the Right Terminal Block?
When selecting a terminal block, it is recommended to focus on:
1. Terminal spacing (Pitch)
2. Current and voltage ratings
3. Wiring method (screw/spring/pluggable)
4. PCB mounting method
5. Frequency of future maintenance
Conclusion:
Whether it's pluggable terminals, PCB-mounted terminals, or spring terminals, choosing the right terminal solution can significantly improve system stability.

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.
First and foremost, the materials used in the terminal blocks play a crucial role in their overall quality. The insulation housing should be made of flame-retardant engineering plastic, while the conductive components should be made of copper alloy materials. This is because the plastic insulation material and the conductive components directly influence the quality of the terminal block, determining its insulation and conductivity functions.In addition, the production process of the terminal blocks is also critical. If the production process is not up to standard, the thread processing is not done properly, and the torque is not within specifications, the terminal block will lose its ability to connect wires effectively.Furthermore, the appearance of the terminal blocks is also important. A high-quality terminal block should not only meet the functional requirements, but also have a visually appealing appearance. A well-designed terminal block can make a positive impression on users and enhance the overall user experience.In conclusion, when it comes to high-quality terminal blocks, it is essential to consider the materials used, the production process, and the overall design of the product in order to ensure optimal performance and reliability.
