Abstract
The utility model discloses a waterproof and radiating structure for a circuit board box cover. The waterproof and radiating structure is characterized in that waterproof ribs are arranged on the periphery of through holes of the circuit board box cover; one side of each waterproof rib is formed into a waterproof top cover disposed above the corresponding through hole and the other side is a waterproof turnup located below the waterproof top cover; and a ventilation opening formed between the waterproof top cover and the waterproof turnup is located on a vertical plane. The waterproof and radiating structure achieves the effects of ventilation, heat dissipation and water resistance. The ventilation openings are formed on the vertical planes, so that condensed water is effectively prevented from seeping into a circuit board via the ventilation openings and the electric safety is guaranteed.
Description
Technical field
The utility model relates to a kind of circuit board lid waterproof radiating structure.
Background technology
Usually can design a lid for the protection of circuit board element and electrical protection on circuit board; but electric component is in operation and can produces amount of heat; therefore some through holes can be set usually for heat radiation; but machine can produce condensed water while moving under varying environment; condensed water may be by the through hole for heat radiation; enter on circuit board, thereby have influence on electrical safety.
The utility model content
The utility model is for avoiding the existing weak point of above-mentioned existing structure, and a kind of circuit board lid waterproof radiating structure is provided, so that the circuit board lid can dispel the heat and can waterproof, guarantees electrical safety.
The utility model is that the technical solution problem adopts following technical scheme:
The characteristics of the utility model circuit board lid waterproof radiating structure are: the periphery at the through hole of circuit board lid arranges waterproof rib, described waterproof rib forms in a side water-proof top cover, the opposite side be positioned at above through hole and is positioned at waterproof flange below described water-proof top cover, and the ventilating opening be formed between described water-proof top cover and waterproof flange is positioned on the plane perpendicular with the circuit board lid.
Compared with the prior art, the utility model can ventilation and heat, again can waterproof, and its ventilating opening is formed on perpendicular, can effectively avoid condensed water to infiltrate on circuit board by ventilating opening, guarantees electrical safety.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation;
The A-A view that Fig. 2 is Fig. 1;
Number in the figure: 1 circuit board lid, 2 through holes, 3 water-proof top covers, 4 waterproof flange, 5 ventilating openings.
Embodiment
Referring to Fig. 1 and Fig. 2, in the present embodiment, circuit board lid waterproof radiating structure is that periphery at the through hole 2 of circuit board lid 1 arranges waterproof rib, waterproof rib forms in a side water-proof top cover 3, the opposite side be positioned at above through hole and is positioned at waterproof flange 4 below water-proof top cover 3, the ventilating opening 5 be formed between water-proof top cover 3 and waterproof flange 4 is positioned on the plane perpendicular with circuit board lid 1, shown in Fig. 2, is on perpendicular.
In the present embodiment for the heat radiation ventilating opening in perpendicular, surrounding is subject to the encirclement of water-proof top cover and waterproof flange, the heat radiation in also can play reliable waterproof action.
Claims (1)
