What device connects two or more conductors using mechanical pressure without solder?

The device that connects two or more conductors using mechanical pressure without solder is known as a pressure connector. Pressure connectors achieve connectivity by using a mechanism that compresses a conductive element against the wire, ensuring a reliable electrical connection without the need for soldering. This method is particularly advantageous in situations where soldering may be impractical or where the wires may need to be disconnected and reconnected frequently.

Pressure connectors, also referred to as wire clamps or crimp connectors in some configurations, provide a secure connection that is less susceptible to loosening over time compared to some other methods. They are commonly used in various low-voltage applications, making them a practical choice for professionals in the electrical and low-voltage special systems fields.

While connector blocks and terminal strips serve also to connect wires, they typically require additional components or methods, such as screws, to secure the connection properly, while wire nuts are designed for twisting together multiple wire ends rather than applying mechanical pressure directly to a single conductor.
