How do cold-pressed ring terminals achieve a reliable electrical connection?
2026-05-03 [ Industry News ]
The cold-press ring terminal is an electronic component that establishes a reliable connection between a wire and an electrical device through the application of mechanical pressure; it belongs to the category of ring-type crimp terminals. Its primary function is to secure a wire to the terminal using a cold-press process—serving as an alternative to traditional soldering methods—making it suitable for low-frequency electrical connection applications, such as power line connections in electrical equipment and devices. Featuring brass contacts with a tin-plated surface finish, this terminal off......
Press-Type Quick-Connect Terminal
2026-04-22 [ Industry News ]
Press-fit quick-connect terminals fundamentally utilize the physical deformation of elastic metal springs to secure wires. When a wire is inserted into the terminal port, the internal spring is forced open and then rebounds, generating a continuous, uniform clamping pressure. This design eliminates the need for screw tightening, thereby preventing the issues—such as overheating or poor contact—that often plague traditional wiring due to loosening, oxidation, or insufficient contact surface area⚠️. The international electrical standard IEC 60998-2-1 explicitly mandates that such terminals must ......
The function of a low-voltage circuit breaker
2026-04-13 [ Industry News ]
A low-voltage circuit breaker is a type of switchgear that integrates control and protection functions. It is mainly used in power distribution systems with an AC voltage of 1000V or a DC voltage of 1500V or below. It can both manually or electrically connect and disconnect circuits, and can also automatically cut off the power supply when a fault occurs in the circuit to ensure electrical safety. Core protection functions1. Overload protection: When the line current exceeds the rated value and persists for a certain period of time, the circuit breaker will automatically open to prevent e......
The Difference Between Terminal Blocks and Copper Lugs？
2026-04-11 [ Industry News ]
1. Definitions and Functions**Terminal Blocks****Definition:** A terminal block is an accessory product used to facilitate electrical connections. Typically installed between wires and electrical equipment, it serves the function of transmitting electrical current and signals. **Function:** Its primary purpose is to simplify the connection and disconnection of wires while ensuring the reliability and safety of the electrical connection. Terminal blocks can streamline the installation process, enhance maintenance efficiency, and reduce the failure rate caused by poor contact. **Copper......
Are copper terminal blocks heat-resistant?
2026-04-10 [ Industry News ]
**Key Temperature Resistance Characteristics*** **Pure Copper (Red Copper):** Melting point of approximately 1083°C; features high thermal conductivity (approx. 401 W/(m·K)), enabling rapid heat dissipation to prevent localized overheating.* **Brass:** Composed of copper and zinc; exhibits relatively poor temperature resistance with a lower melting point (approx. 900–940°C) and is prone to softening and deformation at high temperatures.* **Tin-Plated Copper Terminals:** According to the national standard GB/T 14048.1-2023, at an ambient temperature of 40°C, ......
