Specific implementation mode
Below in conjunction with the accompanying drawings, the utility model is described further.
As shown, a kind of safe small power transformer, including shell 1, coil group 2, coil rack 3, terminals
Son 4, square through hole 5 and mounting hole 17, square through hole are arranged on shell, and mounting hole is arranged in square through hole opening both sides
Housing side on and have per side several mounting holes, it is some of be located at the side surface upper part, other is located under the side
Portion, coil group are arranged in square through hole, it further includes terminal mounting plate 6, shell mounting base 7 and baffle 8, the terminal installation
Plate, shell mounting base and baffle it is equal there are two, be located at square through hole opening both sides, with positioned at square through hole be open both sides shell
It is both provided with the first reinforcing rib 9 in the adjacent shell two side walls of body sidewall, housing bottom opens up fluted 10 and groove both ends
Notch is formed in the two side walls for being provided with the first reinforcing rib, groove slot bottom offers several heat emission holes, the connecting terminal
It is detachable to be fixedly connected on terminal mounting plate, terminal mounting plate mounting hole, terminal peace are offered on the terminal mounting plate
Loading board mounting hole is corresponding to the position of housing side upper mounting holes, and the shell mounting base is equipped with shell mounting base mounting hole
