Introduction

Terminal blocks, sometimes referred to as board-to-wire connectors, are electrical connectors designed to join two separate electrical circuits together. They serve as a kind of cable joining technique, allowing reliable and efficient interconnection of equipment and protecting against unwanted electrical transients. Terminal blocks come in a variety of styles, colors, and sizes to meet various requirements.1786630000 or 17866-30000 are terminal blocks designed for use in wire-to-board connections. It is designed for mating with 3.81mm (0.15 in) pitch flat ribbon cable. It consists of 3.2mm (0.126 in) male and female contacts. The contact design ensures reliable contacts for a wide variety of wire sizes and shapes. There is a locking lever which varies in design depending on the type of application. This locking mechanism securely grasps a round or flat wire, eliminating the need of a strain relief.

Design Features

The 17866-30000 terminal block features a modularized design that enables easy assembly and is suitable for a wide range of applications, including automotive, power supplies, and telecoms. The terminal block can be snapped onto the board, eliminating soldering and providing strain relief for the captive wires. It is designed for reliable connections while eliminating wire misconnections. The two-piece terminal block design utilizes a one-piece contact as well as a quick-connect terminal, allowing for fast and easy installation. The contact and terminal are both screw-type and can be combined seamlessly during installation.The 17866-30000 terminal block is UL recognized, CSA certified, and RoHS compliant. It is constructed from corrosion-resistant materials and is designed to withstand extreme temperatures. It is available in three colors: green, black, and white. The terminal block is rated for a maximum current of 10A and a dielectric strength of 250V.

Working Principle

The 1786630000 terminal block operates by connecting two metallic conductors. The male contact of the terminal block acts to conduct the electrical current from the male conductor to the female conductor at the other end of the terminal block. When the two metallic conductors are connected, the current flows through the wire to the connection point of the female contact in the terminal block.When the male contact is inserted into the female contact, the two contacts come together and create an electrical connection. This connection completes an electrical circuit. The terminal block also provides isolation, preventing the current from traveling in the opposite direction. This ensures that only the intended current is passing through the terminal block.

Conclusion

The 17866-30000 terminal block is a reliable and efficient interconnection solution that is perfect for a variety of applications. It is designed to withstand extreme temperatures and can be quickly and easily installed. The terminal block is UL recognized, CSA certified, and RoHS compliant. The two-piece design utilizes a one-piece contact as well as a quick-connect terminal, allowing for maximum reliability without the need for soldering.
