3215915 Connectors, Interconnects

Terminal Blocks, also known as Din Rail, Channel, are the components responsible for linking and connecting two or more circuits or circuits. Din Rail, Channel is widely used in many areas such as industrial automation, instrumentation, test and measurement, and it also serve as an important component for power distribution and acquisition of ground loops in circuit design.

In terms of 3215915 application field and working principle, terminal blocks is a kind of connection components,can connect wires or cables of tested signals of electrical equipment, used to ensure the reliable transmission of measuring signals in electric power system. According to size, materials, switching signals, etc., terminal blocks of different types can provide a variety of coding and connection options, which are widely used in thermal power plants, substations, factories, mines, etc. With regard to working principle, terminal blocks are basically structured by a combination of an accelerated contact spring and a special shaped plug.

Terminal Blocks of Din Rail, Channel can be further classified into two kinds, first one is a Din Rail mount terminal block, the other is called solderless terminal block.

Din Rail mount terminal block is the most common type of terminal block. It has a shape that is punched into a groove of a steel block called a DIN rail. This flat-cut terminal block is the most cost-effective type of terminal block and is often used on machine equipment and small motor control gear.

Solderless type terminal blocks have features such as no use of solder, no difficult wiring, and the ability to quickly splice or repair the contact point at any time. To use solderless type terminal blocks, generally require pre-formed termination components, such as pre-twisted or pre-crimped wire. Depending on whether the termination requires insertion or not, the solderless terminal block is divided into plug-in type and non-plug-in type. The plug-type solderless terminal gives multiple contacts with positional accuracy and can handle high frequencies by means of contact denticles. Non-plug-in solderless terminal refers to spring-clamp type or screw-clamp type, which is cheaper than the plug-in type, but is not so reliable.

In short, Din Rail, Channel are the components responsible for connecting two or more circuits which plays a decisive role in terms of industrial automation, instrumentation, power generation and other fields. And 3215915 application field and working principle are that terminal blocks can provide a variety of connection options, Din Rail mount terminal block and solderless terminal blocks are two most common types.
