State terminal mounting plate, shell mounting base and baffle it is equal there are two, be located at square through hole opening both sides, the connecting terminal can
It is detachably fixed and is connected on terminal mounting plate, terminal mounting plate mounting hole, terminal installation are offered on the terminal mounting plate
Plate 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,
Shell mounting base mounting hole is corresponding to the position of housing side Lower mounting hole, and kidney slot, baffle are provided in shell mounting base
Upper and lower part be both provided with, the baffle corresponding to terminal mounting plate mounting hole position of location hole and baffle top location hole
The location hole of lower part is corresponding to shell mounting base mounting hole position, and coil group end and coil can be accommodated by being offered in the middle part of baffle
The cavity of skeleton end, baffle top, which contacts with terminal mounting plate bottom and opens at the top of baffle, is equipped with threading via hole, and threading leads to
Hole is connected to cavity, axially vertical, the position of position and coil rack gap that opens up of the axial direction of threading via hole and square through hole
It sets corresponding.
The utility model has the beneficial effects that：It is simple in structure after using this structure, to original transformer shell
Structure does not change, and facilitates the manufacture of transformer.The connecting pin of coil and coil and connecting terminal can be prevented to be exposed to outer, just
It in the dismounting of connecting terminal, convenient for wiring and can be good at playing protection effect, improve service life so that transformer passes through
It is durable long.

Specific implementation mode
Below in conjunction with the accompanying drawings, the utility model is described further.
As shown, a kind of durable small power transformer, including shell 1, coil group 2, coil rack 3, terminals
Son 4, square through hole 5 and mounting hole 6, 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 7, shell mounting base 8 and baffle 9, the terminal installation
Plate, shell mounting base and baffle it is equal there are two, be located at square through hole opening both sides, the detachable fixation of connecting terminal
Be connected on terminal mounting plate, offer terminal mounting plate mounting hole on the terminal mounting plate, terminal mounting plate mounting hole with
The position of housing side upper mounting holes is corresponding, and the shell mounting base is equipped with shell mounting base mounting hole 10, shell installation
Seat mounting hole is corresponding to the position of housing side Lower mounting hole, and kidney slot 11, the top of baffle are provided in shell mounting base
, the baffle lower part corresponding to terminal mounting plate mounting hole position of location hole 12 and baffle top location hole are both provided with lower part
Location hole it is corresponding to shell mounting base mounting hole position, coil group end and coil rack can be accommodated by offering in the middle part of baffle
The cavity 13 of end, baffle top, which contacts with terminal mounting plate bottom and opens at the top of baffle, is equipped with threading via hole 14, and threading leads to
Hole is connected to cavity, axially vertical, the position of position and coil rack gap that opens up of the axial direction of threading via hole and square through hole
It sets corresponding.
