PCB screw terminal block is used extensively in building wiring for the distribution of electricity - connecting electrical outlets, luminaires and switches to the mains, and for directly connecting major appliances such as clothes dryers and ovens drawing in excess of 15 amperes. PCB screw terminal blocks are commonly used to connect a chassis ground, such as on a record player or surge protector. Most public address systems in buildings also use them for speakers, and sometimes for other outputs and inputs. Alarm systems and building sensor and control systems have traditionally used large numbers of screw terminations.
PCB direct welding screw type terminal block is one of the branches of the whole connector, but its main characteristics are the same. It mainly gives play to its main performance through connection, and plays a relatively large role in different fields. For example, in the power industry, wiring terminal is mainly a plug-in connection equipment, which is mainly used for control and connection. It is also very convenient to use. PCB direct welding screw type terminal block is a basic accessory used to realize electrical connection. It is a fixed part connecting the end points or contacts between wires, appliances and control boards, which is called wiring terminal. The function of PCB direct welding screw type terminal block is to ensure that the electrical connection is firm, safe and beautiful, and improve the convenience and rapidity of electrical installation and maintenance.
Pluggable PCB terminal block with screw lock is a series of products with a push-in-design for connecting wires to the terminal blocks which are used to realize the electrical connection of electronic components. It is usually used in the distribution box, which is more convenient for wiring, and generally bears less power. The pluggable terminal block connector is composed of two parts: one part compresses the wire and then plugs into the other part, which is welded to the PCB board. The mechanical principle of the connection bottom and the anti-vibration design ensure the long-term airtight connection of the product and the use reliability of the finished product.
