ATSC4R is a broadcast standard established to enable reliable digital television broadcasting. Its backbone is the technology of UHF/VHF transmission medium. By relying on the compressed signal technology, it not only has a stable and strong broadcasting signal, but also provides a wide range of broadcast services. In addition, ATSC4R can also provide service coverage to the rural and remote areas in the coverage area.

In terms of terminals, ATSC4R terminals, also known as TV sets, are divided into two categories: digital TV sets and set-top boxes. In terms of connection, ATSC4R terminals use corresponding terminals such as DIN rail terminal blocks.

DIN rail terminal blocks is a kind of terminal, which is a Kind of Double connection technology, which has superior characteristics of fast connecting and reliable connection. In addition, the use of special DIN rail terminal block also greatly reduces the installation space. The DIN rail terminal block is composed of a central busbar, side connected terminal and downstream connected terminal, which is the terminal connection interface commonly used in various control systems. The features of the DIN rail terminal block are compatible with dynamic current, high temperature resistance, and high pressure withstand.

Channel type terminal blocks is one of the basic terminal form of channel type distribution devices, it has two kinds of terminal block interlocked structure and open two terminal blocks, respectively, suitable for 14-22 AWG wire (0.2 ~ 6.0mm2). Channel type terminal blocks on each terminal has a contact spring, when in use, just insert the contact spring into the terminal block, the wire can be connected to the terminal block, which is also the biggest advantage of the terminal block, it is very convenient to use.

The working principle of the terminal block is quite simple. After the terminal block is installed on the device, the electric signal wiring can be connected directly, which is convenient, quick, low cost and reliable. The connection of the terminal block is very reliable, and the contact between the terminals is stable due to the positive and negative spring contact. In addition, the terminals of the terminal blocks are easy to install, easy to operate and very secure.

In conclusion, ATSC4R terminal blocks use DIN rail type and channel type terminal blocks to complete the connection of the whole system. The terminal blocks are characterized by convenient installation, stable connection signal and reliable connection. In addition, the use of these terminal blocks can reduce the size of the wiring system and save the cost.
