What is Safe Terminal Block ?

What is a safe and reliable terminal or connector product? It is estimated that everyone will say circuit safety. How can we make the circuit power safe? It may be difficult to outline clearly except for professional connector manufacturers and industry experts.Today let we're going to be talking about different types of Terminal Block connection types .

First of all, let's first understand the standard requirements of the high-quality terminal products themselves:

We must know that high-quality terminal products should be tested for mechanical structure safety, enclosure protection grade, insulation material, pollution level, leakage tracking index, terminal conductive materials, and anti-shock function. At present, professional manufacturers generally use professional testing equipment to test according to national standards. For example, our company mainly uses automatic 2.5-magnitude imaging instrument, rotary tensile tester, material tester, high-temperature sintering box, glow wire equipment, etc. to test the performance of these products.

In addition, there are differences in the requirements and standards for different series of terminal products:

The spring terminal has great requirements for the spring material and clamping force, must have high tensile strength and high corrosion resistance, and at the same time, the resistance must reach UL94 V-0; similarly, the screw terminal has certain torsion. Claim. If the terminal is mounted on a guide rail, the ability to fasten the clip foot is also an important consideration.

In addition to the above terminals, pluggable terminals and PCB terminals used on PCBs are currently the most widely used terminal products. The former requires that the insertion and removal forces be stable, and the contact resistance cannot increase after difficult insertion or insertion. Large-scale phenomenon; the latter requires that the solder pin material has a high conductivity and a small pin-to-pin tolerance.

Finally, Speed Pro. Xiaobian would like to say that the technical requirements for protection against electric shock and creepage distances and clearances between terminals and terminals, and terminals and other conductive components must meet the relevant standards. At the same time, Xiaobian personally think that the design of the terminal is also a factor that restricts the customer's choice.
