This utility model discloses a mine explosion-proof electrical control box, including an explosion-proof electrical control box body. A first terminal is installed on the upper side of the explosion-proof electrical control box body, and a second terminal is installed on the lower side of the explosion-proof electrical control box body. The back of the explosion-proof electrical control box body is attached to the front of a back plate. A buffer pad is fixed to the back of the back plate. Ear plates are fixed to the top and bottom sides of the back plate. A mounting hole is opened on the upper front of the back plate, and the mounting hole is connected to the rear end of a horizontal threaded rod. A support plate is fixed to the front end of the horizontal threaded rod. A positioning groove is opened at the center of the top surface of the support plate. A mounting groove is opened on the lower front of the back plate, and a locking bolt is installed in the mounting groove. This mine explosion-proof electrical control box adopts a novel structural design, which can not only stably position the connected multi-strand cables and avoid excessive bending damage at the cable connection, but also support and guide the cables, facilitating cable arrangement.

This utility model relates to the field of circuit board technology and discloses a circuit board with a built-in heat dissipation and airflow guiding structure. The circuit board includes a circuit board body with a copper heat-conducting strip embedded inside. A heat dissipation base is connected to the front end of the circuit board body, and a guide pipe is connected to the outside of the heat dissipation base. A heat dissipation fin holder is connected to the front end of the guide pipe, and a cooling fan is mounted on the top of the heat dissipation fin holder. A connector is mounted on the left side of the circuit board body, and a CPU module is mounted on the front end of the circuit board body. This utility model, by setting up a heat dissipation and airflow guiding structure, allows heat to be transferred through the heat dissipation base to the guide pipe and heat dissipation fin holder during use. Then, by activating the cooling fan, the heat on the heat dissipation fin holder is dissipated, thus achieving the heat dissipation and airflow guiding function.
