Terminal Blocks – Wire to Board

Terminal blocks are a type of electrical connection used commonly in the industrial industry and within panel-based and individual equipment designs. Typically disengageable, they are used for joining two or more electrical conductors together in an isolated environment without the need for a continuous connection. Terminal blocks are also known as terminal strips, terminal boards or connector blocks.

995021 application field and working principle are one type of terminal block that is used for wire to board connections. It has a simple and compact design that makes it well suited for densely populated boards. The design of the block requires minimal force to insert a wire into its respective terminal. This is the main difference between a 995021 block and other terminal block types.

995021 terminal blocksare designed to provide a SMD plug-in connection for board to board applications. They are able to secure and pass power and signal between two separate boards without the need for wiring. The terminal block eliminates soldering and is able to provide a reliable connection, even in hostile environmental conditions.

The 995021 Terminal is a 2-part design, using a connector block and a contact block. The connector block is made from an insulating material, often rated to UL V0 (flame retardant). This is important in order to meet fire safety requirements.The contact block is normally plated with either gold or silver and is designed to securely grasp the wire when inserted. Most terminal blocks support wire sizes from 0.2mm² to 6.0mm².

Installation of the 995021 terminal block is a simple and straightforward process. In most cases a groove is placed at the back of the terminal block allowing it to fit over a panel cut-out. The connector block is then snapped onto the contact block with the two parts merging together.

The wire insertion process requires some force as the contact block expands as the wire enters and located into the right position at the base of the connector block. The process is made easier by the use of test probes or an insertion tool, both of which are available from a number of suppliers at competitive prices.

When inserted correctly, the wire is held tightly in place, protecting the full terminal block from sideways movement and ensuring the electrical connection is secure. The upper side of the connector also has an insulating cover that can be snapped into place, helping to improve the overall safety of the system.

In conclusion, 995021 terminal blocks are a type of wire to board connection that is designed to offer an effective and fast connection between two boards. It features a simple and compact design that is easy to install in densely populated boards. The terminal block ensures the connection is secure, even in hostile working environments, making it a popular choice for many applications.
