Power supply with PCB board protection architecture

Technical Field

The utility model relates to a new forms of energy field especially relates to a power with PCB board protection architecture.

Background

Power supplies have been applied to new energy vehicles as one of important devices in the field of new energy. Some new energy vehicles are generally provided with a power supply placing box, and the inner side of the power supply placing box is provided with a plug-in slot for the power supply to be inserted in a matching mode. Referring to fig. 1, a conventional power supply for an automobile mainly includes a cover plate 1 and a PCB 2, the cover plate 1 is formed with a cavity 10 having an opening at a bottom, the PCB 2 includes a PCB body 21 and a plugging edge 22, the plugging edge 22 is directly formed on the PCB body 21, a component, which may be a connector 23, is disposed on the PCB body 21, and the entire PCB 2 is fixed below the cover plate 1. When a power supply needs to be inserted into the inner side of the power supply placing box, the plugging edge of the PCB is inserted into the plugging groove in the inner side of the power supply placing box until the plugging edge is finally plugged in place. Therefore, the traditional power supply is arranged in the power supply arrangement box of the automobile, and the power supply provides electric quantity support for the control work of the automobile.

However, the conventional power supply structure has disadvantages: in the process of arranging the power supply in the power supply arranging box, external force is applied to the power supply, so that the inserting edge of the PCB is inserted into the inserting groove in the power supply arranging box, and once the inserting edge is bent due to the influence of the applied external force, the bent inserting edge can drive the PCB main body to be bent, the normal work of components on the PCB main body is influenced, and the power supply can not be supplied to the outside normally.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a power with PCB board protection architecture is provided to above-mentioned prior art.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: a power supply with a PCB board protection structure, comprising:

a cover plate having a cavity with a bottom opening;

the PCB is arranged at the bottom of the cover plate, the PCB main body is arranged at the opening at the bottom of the cover plate, and the inserting edge is arranged at the outer side of the cover plate;

the PCB is characterized by further comprising a bottom plate, wherein the bottom plate is arranged below the PCB, and the PCB main body is fixed between the cover plate and the bottom plate.

In the power supply with the PCB protection structure, the PCB is provided with two plugging edges which are respectively positioned at the left side and the right side of the PCB main body.

In the power supply with the PCB protection structure, the PCB main body is fixed to the bottom plate and the cover plate by screws, respectively.

In order to improve the heat dissipation effect of the power supply, in the power supply with the PCB protection structure, the cover plate is made of a heat dissipation material.

Further, in the power supply with the PCB protection structure, the cover plate is a metal cover plate.

In a further improvement, in the power supply with the PCB protection structure, a conduit post and a connector are disposed on the PCB main body.

Compared with the prior art, the utility model has the advantages of: the utility model discloses a power among has on the basis of apron and PCB board at traditional power, increases and has set up the bottom plate, sets up the bottom plate in the below of PCB board and makes the PCB board main part fix between apron and bottom plate, and the grafting limit of PCB board is located the apron outside. Like this, when inserting the inserting groove of power arrangement incasement with the grafting limit of power, even if the grafting limit produces the bending because of receiving external force, PCB board main part also can not be because of the crooked bending deformation that produces along with it of grafting limit, has protected the PCB board, has so not only avoided the PCB board main part to receive the damage, but also has ensured the normal work of PCB board to guarantee the external normal power supply of this power.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

The embodiment provides a power supply with a PCB protection structure, which can be applied to an automobile to ensure the normal operation of automobile control. Referring to fig. 2, the power supply with the PCB protection structure of the embodiment includes a cover plate 1, a PCB 2 and a bottom plate 3, wherein the cover plate 1 is made of a heat dissipation material, for example, the cover plate 1 is a metal cover plate, and the cover plate 1 is formed with a cavity 10 with an opening at the bottom; the PCB 2 is provided with a PCB main body 21 and two inserting edges 22, the two inserting edges 22 are respectively positioned on the left side and the right side of the PCB main body 21, a connector 23 and a conduit column 24 are arranged on the PCB main body 21, the conduit column 24 can represent and display the working state of a power supply, the connector 23 and the conduit column 24 are both positioned in the cavity 10 of the cover plate 1, the PCB 2 is positioned at the bottom of the cover plate 1, the PCB main body 21 is positioned at an opening at the bottom of the cover plate 1, and the inserting edges 22 are positioned on the outer side of the cover plate 1; the bottom plate 3 is disposed under the PCB 2 and the PCB body 21 is fixed between the cover plate 1 and the bottom plate 3.
