The utility model belongs to the technical field of broadcast digital multi-mode receiving and expanding machines, and discloses a broadcast digital multi-mode receiving and expanding
machine which comprises a box body, one side of the box body is provided with a wiring board, one side of the wiring board far away from the box body is provided with a plurality of wiring holes, the box body is internally provided with a structural groove, and one side of the wiring board is provided with a wire placing groove. A wire containing box is fixedly connected into the wire containing groove, one end of the wire containing box extends into the structural groove, and a connecting wire is arranged on one side of the wire containing box. According to the device, through cooperative use of the rotating shaft, the heat dissipation groove and the heat dissipation fan, heat dissipation can be effectively carried out on the whole box body, normal use of the broadcast digital multi-mode receiving and amplifying
machine is prevented from being affected by overheating, through arrangement of the filter screen, external dust can be effectively prevented from entering the box body to damage internal elements, and the service life of the broadcast digital multi-mode receiving and amplifying
machine is prolonged. Through cooperative use of a compression spring, a
sponge layer and a protective shell, the box body can be effectively protected, and the broadcast digital multi-mode receiving and expanding machine is prevented from being damaged due to falling or external
impact.
