Terminal blocks are a type of electrical connector comprising terminals arranged in tabs or blocks that can be connected to, or disconnected from, the electric circuit or other external components. The type of terminal blocks covered in this article are the headers, plugs, and sockets.

The 1776481-3 terminal block is a 4 Pre-Insulated female tab to male socket terminal block. It has 4-way flat sockets and tabs, and is rated for 250 Volts (250V) and 4A. The terminal block uses connection technology to enable quicker and more secure assembly than traditional socket/tab connections.

The 1776481-3 terminal block has several applications in the electrical and electronic industries. They can be used, for example, to interconnect wires and other components in electrical and electronic equipment, or to couple connectors on printed circuit boards. The low profile design of the 1776481-3 is ideal for applications where multiple connections need to be made in a small space.

The working principle of the 1776481-3 terminal block is relatively straightforward. When the terminal block is pressed against a mating connector, the resilient female tabs spring out and grip the male sockets. The sockets are then held firmly in place with the tabs, and the electrical connection is established. The connection is further secured by the locking screws, which are easily tightened by hand.

The 1776481-3 terminal block offers various advantages over traditional wiring methods. It is easy to assemble, saves time, and provides secure electrical connections. It is also corrosion-resistant, making it suitable for a range of applications. The terminal block is RoHS compliant, flame-retardant, and designed to meet UL94V-0 standards.

In summary, the 1776481-3 terminal block is a 4 Pre-Insulated female tab to male socket terminal block. It is easy to assemble and provides secure electrical connections, and is suitable for a range of applications. Its working principle is that when the terminal block is pressed against a mating connector, the resilient female tabs spring out and grip the male sockets, and the connection is further secured by the locking screws.
