At present, as shown in fig. 1 and 2, a power module 400 and a plurality of daughter boards 300 are disposed side by side on one side of a motherboard 200, and the width of the electronic card is relatively large. In order to reduce the width of the electronic plug-in box, some electronic plug-in boxes are provided with a power module outside the box body, and the power module and a main board inside the box body are connected through a plurality of cables. However, in some places with severe electromagnetic environments, the transmission of the power provided by the power module in the cable may be disturbed due to the longer path of the current transmission between the power module and the motherboard caused by the cable, and particularly when the voltage provided by the power module is low, the anti-interference capability is weak, which results in a degradation of the quality of the power provided by the power module. In other electronic enclosures, the number of power boards in the power module is reduced by increasing the size of the power boards in the power module, and the width of the electronic enclosure is reduced by reducing the width of the power module. However, after the size of the power board is changed, the size of the main board and each of the sub boards also need to be changed, which increases the design cost and the design cycle of the electronic plug box.

Through repeated thinking and verification, the inventor finds that if the power module is fixed on one side of the main board, which is away from each daughter board, the main board is electrically connected with the power module through a plurality of electrical connectors. Therefore, the power module and each daughter board are respectively located on two opposite sides of the main board, the width of the electronic plug box is effectively reduced, and in addition, the transmission path of current between the power module and the main board is shorter, so that the power provided by the power module is not easy to be interfered, and the power quality provided by the power module is ensured. Meanwhile, the structure of the daughter board does not need to be changed, which is beneficial to reducing the design cost and the design period.

In view of this, the inventor devised an electronic plug-in box, in which a main board is mounted in a box and located at a second side of the box, each sub-board is mounted in the box and located at a side of the main board facing a first side of the box, a power module is disposed at an outer side of the box and fixed to the box, and the power module is located at a side of a back ion board of the main board, and the power module is electrically connected to the main board through a plurality of electrical connectors. Therefore, the width of the electronic plug box is effectively shortened, and meanwhile, the quality of the power supply provided by the power supply module can be guaranteed.
