While electronic circuits can process signals and produce outputs, they almost always need to be connected to external components, power sources, inputs or outputs. These connections are done with the use of Terminal Block Connectors, and they come in many different types, shapes, sizes and ratings. Choosing the wrong Terminal Blok connector for your design can cause a range of issues, from bulky product sizes to components catching fire, so understanding the different types of connectors is imperative. And while there are many connector types available (pin headers, sockets, DIN and DB, for example), this article will focus on terminal blocks specifically, since they are found in just about every single sector, ranging from domestic wiring to industrial rack systems connecting to various I/O.
In particular, when the terminal in the connection is short-circuited due to burnout, the advantages of the terminal will appear. After power failure, it can immediately take out the burned terminal replacement of the same type of new products, thus greatly shortening the maintenance time. For general wiring terminals, they are mainly divided into the following connection modes:
Screw connection adopts screw terminal connection, with maximum tightening torque of different specifications of screws
The most common type of welding is tin welding. The most important part of the solder connection is that the metal continuity should be formed between the solder material and the welded surface.
Crimping is a technique of connecting wires to contact pairs in order to compress and displace the metal within specified limits.
Wire Wrap Connection
Wire wrap is the direct winding of the wire on the angular contact winding column. When winding, the wire is wound under controlled tension, pressed into and fixed at the edges and corners of the contact-wrapped column to form an air-tight contact.
Puncture connection, also known as insulated displacement connection. It is suitable for connecting ribbon cable.
