Terminal blocks or also called terminal boards or strips are electrical devices used to connect two or more electrical wires or cables. They are similar to a track side strapping devices but typically used on a different scale. Often termed jumper wires, they are available in a range of sizes and materials and identified by part number like 1803439. As they form a secure, reliable connection, terminal blocks are very useful in constructing a secure, reliable circuit.

Conductor Type

One of the major classifications of 1803439 terminal blocks is conductor type. This classification includes screw-type, spring-type and pluggable-type terminal blocks. Screw-type terminal blocks require a screwdriver to connect wiring, while spring-type terminal blocks use spring-loaded terminals to easily connect wiring. Pluggable-type terminal blocks use modular blocks in a U-shaped design to allow quick connections and ampacity control. In addition, insulated terminal blocks are another popular type.

Current and Voltage Rating

Current rating and voltage rating are two additional important classifications of 1803439 terminal blocks. Current rating is an indication of the maximum current the terminal block can safely carry without overheating or arcing of the component. Voltage rating indicates the maximum voltage the terminal blocks are rated to safely handle. Terminal blocks can also be classified as low voltage, medium voltage, and high voltage, depending on the ratings.

Functional Specification

The functional specifications of 1803439 terminal blocks include the spacing between terminals, the size of the hole to be punched out, and the pitch of the terminals. Spacing of the terminals refers to the distance between pins. The size of the hole to be punched out is important to ensure that the wire can pass through the hole securely and that the terminals can be connected. The pitch of the terminal refers to the distance center sided between two adjacent terminals.

Application Field and Working Principle

Terminal blocks, like the 1803439 model, are widely used in many field, such as industrial automation, home automation, communications systems, control panel design, LED lighting systems and more. In these fields, the terminal blocks are used to provide an efficient method to interconnect components within a device. The main working principle of terminal blocks is to provide a secure, reliable connection between electrical components. Over time, manufacturers have developed multiple terminal block types that offer various features such as current and voltage ratings, number of pins, spacing between pins, and a variety of materials.
