What does the environmental performance of a connector refer to?

7 月 18, 2023 通过 admin 0 评论

When selecting connectors, we often consider the environmental performance and understanding what it entails. Specifically, what does the environmental performance of a connector refer to?

1.Temperature resistance Currently, the upper operating temperature limit for connectors is 200°C, excluding a few specialized high-temperature connectors, and the lower temperature limit is -65°C. Since connectors generate heat at the contact points during operation, resulting in temperature rise, it is generally recommended that the operating temperature equals the sum of the ambient temperature and the contact temperature.

2.Moisture resistance The intrusion of moisture can affect the insulation performance of connectors and cause rusting of metal components. The conditions for constant damp-heat testing include a relative humidity of 95% and a temperature of +40±20°C, with a minimum test duration of 96 hours as specified by product requirements. Alternating damp-heat testing is even more rigorous.

3.Salt Spray Resistance When connectors operate in environments containing moisture and salt, the metal structural components and contact surfaces of the connectors may undergo electrochemical corrosion, affecting the physical and electrical performance of the connectors. To assess the connector’s ability to withstand this environment, salt spray testing is conducted. This involves suspending the connectors in a temperature-controlled test chamber and spraying them with compressed air carrying a specified concentration of sodium chloride solution to create a salt spray atmosphere. The exposure time is determined by product specifications, typically lasting at least 48 hours.

4.Vibration and Shock Resistance Vibration and shock resistance are important performance characteristics of electrical connectors, particularly in special application environments such as aerospace, railway, and transportation. They serve as important indicators for evaluating the mechanical robustness and electrical contact reliability of electrical connectors.

The above are the four key points of common connector environmental performance criteria. In addition to these, other environmental performance aspects of electrical connectors include sealing capability, liquid immersion, and low pressure resistance.

Introduction to 5 common wiring methods for terminal connectors:

7 月 18, 2023 通过 admin 0 评论

Terminal connectors enable safe, reliable, and efficient electrical connections, and are used in fields such as power electronics, electrical control, and power supply for signal and voltage transmission. Additionally, using terminal connectors for wiring results in a neater appearance and facilitates maintenance in the long run.

There are five common wiring methods for terminal connectors:

1.Insulation displacement connection:

Also known as IDC (Insulation Displacement Connection), it features high reliability, low cost, and ease of use, making it suitable for flat cable connections. In this method, there is no need to strip the insulation layer of the cable. The pointed tip of the “U”-shaped spring contact of the terminal connector pierces the insulation layer, allowing the cable conductor to slide into the slot of the spring contact and be clamped, forming a tight electrical connection.

2.Screw connection:

The screw connection method uses a screw-type terminal block for connections. It is important to consider the permissible maximum and minimum wire cross-sections for the connection, as well as the maximum tightening torque allowed for different screw specifications.

3.Crimping:

 Crimping is a technique used to compress and displace metal within defined limits in order to join wires to contact pairs. A good crimp connection results in the flow and intermixing of metals, causing symmetrical deformation of the wire and contact material. This type of connection is similar to cold welding and offers excellent mechanical strength and electrical continuity, making it suitable for harsh environments. However, crimping is a permanent connection method and can only be used once.

4.Welding:

The most common form of welding is soldering, where the crucial aspect is the formation of a continuous metallic bond between the solder and the surface being soldered. Therefore, for terminal connectors and cold-pressed terminals, solderability is of utmost importance.

5.Wrapping:

Wrapping involves directly winding the wire around the angular post of a contact component. During wrapping, the wire is wound, pressed, and secured at the angular post of the contact component under controlled tension to form an airtight connection.
