Products in the terminal strip and turret board family are interconnect products consisting of an array of solderable terminals or terminal posts mounted to a sheet of insulating material, most commonly used as a junction point between the inner workings of a device or system and the external wiring connected to it during the course of installation. Relatively simple and inexpensive to produce, they're often found in older equipment, though solderless terminal blocks are generally preferred for such tasks in modern applications.
