Terminal blocks are some of the most versatile and important components in any electrical equipment. It is necessary to understand the different types of terminal blocks, their applications and workings, to get the most out of them.

This article aims to provide an overview of the ‘999411’ terminal block, which is a type of wire to board. Whilst other block types are available, the 999911 block allows the neatest connection of individual wires to the printed circuit board, making them ideal for prototyping or even production.

999411 Application field

The 999911 terminal block provides a secure connection between a single wire and a circuit board. The connection is best suited to small signal circuits, such as digital, analog or AC/DC. The security of the connection ensures that there are no environmental conditions, such as vibration, humidity or dust, which could cause the connection to be lost or corrupted.

The terminal block is especially useful in prototyping, where the connection between a number of test components (such as inputs for sensors) and a circuit board need to be made quickly and easily. It is also well suited to production, albeit in lower quantities than other block types.

999411 Working Principle

The 999911 terminal block operates using a simple principle, called the ‘claw on wire’ principle. This principle revolves around the three parts of the block: the conductive terminal, the insulation housing and the actuator (claw).

The wire is inserted into one end of the block, into the insulated housing. The actuator is then pushed down onto the wire, and the conductive terminal bites into the wire, creating a secure contact. The wire can then be easily disconnected by pushing the actuator again.

The security of the connection is ensured through notching, which involves the conductive terminal biting into the wire. The notching creates cuts in the outer sheath of the wire, which helps to increase the grip of the contacts.

999411 Proficiency

The 999911 terminal block has some unique advantages that make it the perfect choice for certain applications. Firstly, its small size means that it is perfect for use in densely packed applications. Secondly, the actuator makes connection and disconnection easy and safe. Thirdly, the ‘claw on wire’ principle ensures that the connection is secure, regardless of the environment. Finally, the notching of the wire enhances the grip of the contacts, ensuring that the connection is always secure.

These advantages make the 999911 terminal block the perfect choice for any situation where secure connections need to be made between a single wire and the circuit board. Whether it is used for prototyping or production, the 999911 terminal block provides a secure and reliable connection.
