In terms of the function of 1776267-6, the terminal is connected directly to mains, transformer or battery. The contact parts of the terminals are made of conductive phosphor-bronze. The contact surface is plated with Au to guarantee a superior service life and enhanced conductivity.1776267-6 is equipped with a clamping-yoke spring, which can compensate for positioning tolerance and provide a fixing force. With this mechanism, wires of multiple sizes can be connected. The free ends are tensioned so that the insert/housing can be mated with the connective contact point without entanglement.The general specifications of 1776267-6 include a 2.5mm2 veneer tappet, 1100N (250 lbf) contact resistance, 15.5m (1.5A) contact resistance, Degrees of protection to IP20, 22000 cycles of dielectric strength and -25°C to 85°C operating temperature range.

In general, the working principle of a 1776267-6 terminal block is simple. It consists of two parts-the action plunger and the contact spring. The plunger is connected to the control knob, and the contact spring holds the wire firmly against the contact point. When the user applies force to the plunger, the wire is clamped firmly onto the contact point thus establishing a connection between the two elements. The plunger and contact spring are designed to ensure that the connection is held in place even when subjected to vibration or extreme temperatures.The design also allows for a quick and easy disconnection of the wire. The user can simply depress the plunger to release the wire. This disconnection feature is important in applications requiring frequent maintenance or upgrades.

In conclusion, 1776267-6 is ideal for wire to board connections. It has an easy installation and handling, and various pinning, forming and guiding options. The electrical capacity is up to 6A and 600V, with various board options. Additionally, it is equipped with a clamping-yoke spring, which ensures a fixing force and durable connection. All the electrical and mechanical properties and functions of 1776267-6 enable it to be used in a wide range of applications.
