Abstract
The utility model discloses a circuit board structure, comprising a circuit board body and a power supply assembly, characterized in that the circuit board body is provided with a protective apparatus, the power supply assembly is arranged inside the protective apparatus, and the protective apparatus is provided with a through hole. The circuit board structure enables the sealing protective apparatus to be arranged on the power supply assembly to effectively protect the power supply assembly, thereby having no influence on the application of a switching power supply under the condition of high temperature and high humidity, preventing the power supply from breaking down, and being very safe; and the protective apparatus is also provided with the through hole for radiating heat and discharging water vapour inside the protective apparatus, thereby effectively radiating the heat and discharging the hot water vapour inside the protective apparatus.
Description
[technical field]
The utility model relates to a kind of board structure of circuit.
[background technology]
The control circuit board of existing a lot of household electrical appliance is mounted in the body, and wherein circuit board is directly to expose in body, and the Switching Power Supply assembly on the circuit board also is directly installed on the circuit board; Because electrical equipment is when work; There is steam to enter into body unavoidably, steam is contacted with circuit board, and the power supply module that is installed on the circuit board also can contacts with steam; Electricity can influence the use of Switching Power Supply under the situation of high temperature, high humidity; Cause Switching Power Supply to break down, even blast, user's personal safety is threatened.Also inconvenient to maintenance.
The utility model is exactly to make in view of the situation.
[utility model content]
The utility model has overcome the deficiency of prior art, and a kind of board structure of circuit of effectively protective circuit plate power supply module is provided.
The utility model adopts following technical scheme for solving the problems of the technologies described above:
A kind of board structure of circuit includes the circuit board body, and power supply module is characterized in that described circuit board body is provided with protective device, and power supply module is arranged in the protective device, and described protective device is provided with through hole.
Aforesaid a kind of board structure of circuit is characterized in that described protective device comprises the cavity and the base plate of hollow, and described power supply module places cavity.
Aforesaid a kind of board structure of circuit is characterized in that through hole is arranged on the cavity.
Aforesaid a kind of board structure of circuit is characterized in that power supply module comprises switch transformer, filter capacitor, switch I C, piezo-resistance, protective tube, voltage-stabiliser tube, rectifying tube electronic original part.
Aforesaid a kind of board structure of circuit is characterized in that described power supply module is provided with installation foot.
Aforesaid a kind of board structure of circuit is characterized in that installation foot is electrically connected with the circuit board body.
Aforesaid a kind of board structure of circuit is characterized in that described base plate is provided with and the corresponding installation foot of installation foot hole.
Aforesaid a kind of board structure of circuit is characterized in that described base plate is provided with installation foot.
Aforesaid a kind of board structure of circuit, through hole is arranged on the upper wall of cavity.
Aforesaid a kind of board structure of circuit, through hole is arranged on the sidewall of cavity.
The utility model compared with prior art has following advantage:
The power supply module that the utility model is employed in circuit board is provided with seal protecting device, can effectively protect power supply module, under high temperature, high humidity situation, does not influence the use of Switching Power Supply, avoids power supply to break down, and is as safe as a house.On protective device, also be provided with heat radiation, and the through hole that can the steam in the protective device be discharged, but efficiently radiates heat and the hot vapour in the protective device discharged.

[embodiment]
Below in conjunction with accompanying drawing the utility model is elaborated:
A kind of board structure of circuit includes circuit board body 1, and circuit board body 1 is provided with electric capacity, resistance, push-button switch etc., also is provided with power supply module 2 on the described circuit board body 1, also is provided with the protective device 3 that seals up power supply module 2 on the circuit board body 1.
On protective device 3, also be provided with heat radiation, and the through hole 4 that can the steam in the protective device be discharged.
Described protective device 3 comprises the cavity 31 of hollow and with the base plate 32 of cavity 31 sealing, and cavity 31 can adopt waterproof, insulating material such as silica gel to process, and described power supply module 2 places cavity 31.After power supply module 2 placed cavity 31, with 32 pairs of cavity 31 sealed package of base plate, after the encapsulation, protective device 3 can be protected switch power supply module 1 well again, avoids under high temperature, high humidity situation, breaking down.
Through hole 4 is arranged on the cavity 31, and is as shown in Figure 2, can be arranged on the upper wall of cavity 31, and as shown in Figure 1, through hole 4 can also be arranged on the sidewall of cavity 31.After a kind of board structure of circuit work, heat or hot gas that power supply module 2 heating backs produce can be discharged cavity 31 from through hole 4.
On base plate 32, be provided with and installation foot 21 corresponding installation foot holes 321.
