Terminal Blocks - Headers, Plugs and Sockets

Terminal blocks are a type of electrical connector used for establishing electrical circuits within power and control applications. These types of connectors provide a convenient and secure way of connecting multiple wires and cables, with ease. The main types of terminal blocks available on the market are headers, plugs and sockets, all of which have different key characteristics making them suitable for different types of applications.

Headers

Headers are widely used for cable connections, and connecting different electrical components such as circuit boards. Most headers are supplied as either single or double-row terminals and usually feature a insulated plastic cover.
These types of terminal blocks are primarily used for signal connections, as they can provide low-current connections, that are resistant to loosening caused by vibration. Unlike plug and sockets type terminal blocks, they offer less versatility, however they are good options for applications which require long-term reliability.

Plugs and Sockets

Plugs and sockets, otherwise referred to as ‘pluggable terminal blocks’, are a type of terminal block that greatly simplifies the complex process of connecting and disconnecting components. Unlike headers, they have no need for stripping or twisting of wires, instead providing a connector that has already been designed to fit correctly on the wiring harness itself. This feature, in combination with a simple insertion and locking motion, allows for an extremely fast connection.
These types of connectors are particularly useful in applications where quick, convenient connecting is advantageous over time saving. This particular type of terminal block also offers excellent protection against short circuits, accidental contact and other possible dangerous faults.

1862603 Application Field and Working Principle

The 1862603 terminal block is a single pin plug and socket connector, suitable for use in power and control applications. This model is rated for a AC/DC voltage of 1000V and an rated current of 32A. It is available in a wide range of sizes which are measured in DIN pitches (2.5, 5.0, 10.0, and 15.0mm).

The core operating principle of the 1862603 terminal block is its single pin connection. Power and/or control signals are supplied to the connector via a wire or cable, which is then securely locked in place. This is done through the utilisation of a locking mechanism and a screw type fitting that is tightly secured to the contact. The header also features two high strength contact springs, offering a reliable and secure connection by making continuous contact with the supplied wire or cable.
