Introduction

A Terminal Block or Wire to Board connection is a common electrical connection used to join wires to printed circuit boards (PCBs). The 1-1546073-7 is an example of a Terminal Block with a two-part connection system.The two-part connection system makes it easier to install wires on a PCB, as one side consist of a male spade kit that fits into the female spade opening on the PCB. This type of connection is often used for connecting wires with different diameters or lengths, depending on the application.

Features

The 1-1546073-7 Terminal Block has an ergonomic design. It has an insulated two-part system which eliminates the need for costly heat shrink tubing or solder. The terminal block features an internal spring retention clip which secures the male spade firmly into place on the PCB. It also has a controlled force spring retention clip which provides reliable stress relief for the wire connection.The terminal block has two terminal block varieties- a 6-pin and a 9-pin selection. The pin spacing for the 6-pin variety is 2.54mm, while for the 9-pin variety it has a spacing of 2.36mm. The terminal block has a current rating of 30A per pin (150A max) and a voltage rating of 300VAC/DC. It can also be used for tin-plated wire termination.

Application Field and Working Principle

The 1-1546073-7 terminal block is ideal for a wide range of applications, such as consumer electronics, automotive, industrial, medical, and robotics. It is suitable for Wire-to-Wire or Wire-to-Board connections, as well as grounding connections.The working principle of a terminal block is quite simple. The two primary components of the terminal block are the female spade and the male spade. The female spade is secured to the PCB and the male spade is inserted from the other side of the board. The male spade has a spring-loaded clip that sits inside the female spade and secures the connection once the pin is inserted. This ensures the connection is secure and is able to withstand vibrations and shocks.The connection is also protected from corrosion and oxidation. The materials used for the terminal block are chosen for their strength and ability to withstand temperature and environmental changes. The terminal block is also designed to ensure the wires do not come loose and are able to carry the maximum current the wire is rated for.

Conclusion

The 1-1546073-7 terminal block is a reliable and robust connection system used in a variety of electronic, automotive, and industrial applications. It features a two-part connection system with a male and female spade, and an interna spring retention clip which secures the connection. It also features a current rating of 30A per pin and a voltage rating of 300VAC/DC. Its materials and design are chosen for their ability to withstand temperature and environmental changes. This makes the 1-1546073-7 a great choice for a wide range of applications.
