The materials used in Sup products fully meet the requirements of the electronic industry, and all the selected materials have passed the quality inspection procedures of ISO 900 1: 2000 certification. Choosing materials that meet the requirements of environmental protection is one of the important basis for us to choose materials.

As a conductive material, copper has excellent electrical and mechanical properties. Choosing copper materials with different properties can not only meet the forming requirements of Sup terminal for conductive parts, but also meet the electrical requirements in use, and there is no danger of stress cracking. Tin alloy plating on the surface of copper conductor can ensure good contact performance and low contact resistance. Tin alloy coating not only has good electrical properties, but also has good corrosion resistance. Tin alloy surface treatment can protect the solderability of terminals and connector pins of printed circuit boards. In order to improve the wear resistance of the connector, this part also adopts tin alloy, which can also maintain long-term solderability.

In order to meet the actual requirements of different products, different materials can be selected according to specific applications. Nylon 6.6 is preferred as the best insulating material for terminals and connector housings. It is also recognized by almost all international testing institutions. Because of its excellent leakage current breakdown resistance, it reaches CTI 600 according to IEC 1 12 standard, which can reduce the creepage distance between air and leakage current. It has been used as the foundation material of Supu Wharf. Nylon 6.6 is elastic and rigid, and can resist the corrosion of most chemical agents. It is classified as fire extinguishing V-0 or (V-2) according to UL94. The modified nylon 6.6 used by Supra terminal does not contain halogen, fluorocarbon, chlorine-containing carbohydrate, silicone, asbestos, cadmium and formaldehyde, so all insulation materials used by Supra terminal do not contain toxic components.

All clamping springs used in SUPP wharf are made of high-quality, selected and reliable nickel-chromium spring steel CrNi, which has been proved by years of practical experience to have high tensile strength and high corrosion resistance. It can resist sea salt spray, urban waste gas and industrial gases such as sulfur dioxide and hydrogen sulfide. At room temperature of 22℃, it can resist 30% salt solution and 30% dilute phosphoric acid.

The investigation on the actual use of SUP terminals of many customers confirms that taking manual wiring as an example, spring clamping terminals save more than 50% time than threaded terminals. Even if an electric screwdriver is used, spring clamping still has the advantage of saving time. In many cases, the preparation work of wires, such as wire pressing, cold jointing or tin plating, can save more time if it can be omitted. )

Screw clamping connection "depends entirely on the operator", that is, the tightness of screw clamping needs the operator's judgment. This may be controlled to some extent by the setting of a specific torque screwdriver by the operator or manufacturer. When wiring in the field, it is more difficult to ensure proper screw clamping density. The automatic clamping function of the spring allows the unskilled operator to complete high-quality contact connection. No matter who operates, accurate and consistent contact connection can be completed. The tool used is only a standard screwdriver, and the Supu spring terminal has the forms of front connection, side connection and 45-degree connection.

Wiring steps of spring terminal: Insert tool-Insert insulated wire-Pull out tool, and the wire will be automatically clamped.

The super spring terminal-clamping force can be automatically adjusted according to the wire diameter, and the same connection quality can be achieved regardless of whether the operator is skilled or not;

Supu spring terminal-contact can realize air tightness, low contact resistance, corrosion resistance, vibration resistance, impact resistance and extended maintenance.

Unlike screw terminals, spring terminals do not need frequent inspection or re-tightening, and will become loose due to interference, temperature cycling, broken stranded wires, etc. After using the spring terminal, its inherent reliability will reduce downtime and user maintenance times. According to statistics, 35-50% of equipment maintenance is caused by poor contact. Considering the high maintenance cost and the loss of production time, this saving is very meaningful.

For the purpose of safety, reliability and easy troubleshooting, many industry standards and national standards stipulate "one line per card". Supp spring terminals can provide users with two-wire, three-wire or four-wire contact terminals, and adjacent or spaced terminals can be easily connected together by using upper insulation bridges. In both cases, each wire has its own contact clip, and because of the front connection characteristics, it does not need more space than the two-wire terminal.

In the design of spring clamping, the proportional clamping force is given according to different wire numbers. The larger the wire diameter, the greater the clamping force. The flat surface area of the spring matched with the guide rod with special curved surface can provide a firm connection without damaging the wires. At the same time, the angle of the spring is designed as a special property, and when the drawing force is applied, the clamping force also increases.

Supp spring terminals and connectors have complete wire inlets, which can tightly clamp wires. The shell design of Supu, combined with the unique performance of the spring, ensures that the conductor is automatically positioned in the contact area, which can effectively avoid stranded wires.
