Board terminal blocks are components used to electrically connect printed circuit boards. There are different types of terminal blocks, such as plug-in ends, tab ends, freestanding terminals, etc. There are various ways to mount the terminal block, including direct mounting, DIN rail mounting that can be mounted on the DIN rail with a single-action, PCBs that are fixed by soldering or connected by inserting cables, etc. For connection methods there are differences such as screws, screwless, etc. Many terminal blocks are screw terminals that fix mounting holes by processing the holes and binding the cables with screws. The connection direction is also straight or L-shaped, so it is necessary to select it depending on the connection location. Some products offer excellent stability while others are space-saving.
