Circuit board is placed in described groove.
As a kind of embodiment, the operator guards of described circuit board also comprises water proof ring;
Described mounting base arranges seal groove, and circuit board is trapped among centre by described seal groove;
Described water proof ring is pressed in described seal groove by described cover plate.
As a kind of embodiment, described cover plate is fixed on described mounting base by connector.
As a kind of embodiment, described connector is buckle, bolt, screw or pin.
As a kind of embodiment, described cover plate or described mounting base arrange breach, described breach is for placing described wiring sheath.
As a kind of embodiment, described cover plate, described mounting base arrange breach and lower breach respectively, and described cover plate is fixed on described mounting base, and described upper breach is corresponding with the position of described lower breach, form a combination line outlet, for placing described wiring sheath.
As a kind of embodiment, the material of described mounting base is plastics.
As a kind of embodiment, the gabarit of the described groove on described cover plate or described mounting base is round and smooth cambered surface.
Beneficial effect of the present invention is compared with the prior art: the anti-sealing of operator guards of circuit board is splashed to circuit board, and surrounding objects collides circuit board, effectively protective circuit plate, improves fail safe and the useful life of circuit board.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of the decomposing state of the operator guards of circuit board of the present invention;
Fig. 2 is the cross-sectional schematic of the operator guards of circuit board of the present invention.
Embodiment
The problem of easily making moist to solve circuit board, being collided, the operator guards proposing a kind of circuit board realizes the sealing to circuit board.
Below in conjunction with accompanying drawing, to above-mentioned being described in more detail with other technical characteristic and advantage of the present invention.
Refer to shown in Fig. 1, it is the schematic perspective view of the decomposing state of the operator guards of circuit board of the present invention, and the operator guards 100 of circuit board comprises mounting base 110, cover plate 120 and wiring sheath 130.
Circuit board is placed on mounting base 110; cover plate 120 covers on circuit boards; in the cavity that circuit board is enclosed between mounting base 110 and cover plate 120; play anti-sealing and be splashed to circuit board; surrounding objects is avoided to collide the object of circuit board; protective circuit plate effectively, improves fail safe and the useful life of circuit board.
Cover plate 120 is fixed on mounting base 110.
Wiring sheath 130 is placed between mounting base 110 and cover plate 120, and the circuit of circuit board, by wiring sheath 130, is connected with external power source.
More preferably, the material of wiring sheath 130 is rubber, and the size of the intermediate throughholes of wiring sheath 130 and the circuit of circuit board adapts.
As a kind of embodiment, arrange groove in the centre of cover plate 120 or mounting base 110, cover plate 120 is fixed on mounting base 110, and circuit board is placed in groove.General meeting arranges thin slice on mounting base 110, and thin slice snaps in the breach on circuit board, plays the effect of fixing circuit board.
In the present embodiment, arrange groove in the centre of cover plate 120, circuit board is placed in groove, and mounting base 110 is as the mounting platform of the operator guards 100 of circuit board, and its outer surface is plane, to fit to arbitrary installation site, and convenient location.
As a kind of embodiment, the operator guards 100 of circuit board also comprises water proof ring 140, and mounting base 110 arranges seal groove 112, and circuit board is trapped among centre by seal groove 112.
Shown in Fig. 2, it is the cross-sectional schematic of the operator guards of circuit board of the present invention, and when cover plate 120 is fixed on mounting base 110, water proof ring 140 is pressed in seal groove 112 by cover plate 120.
More preferably, the material of water proof ring 140 is rubber, and the pressure produced when cover plate 120 is fixed and power make water proof ring 140 produce slight distortion, and fitting cover plate 120 and mounting base 110 respectively in the two ends of water proof ring 140, makes the better tightness of the operator guards 100 of circuit board.
As a kind of embodiment, cover plate 120 is fixed on mounting base 110 by connector.
As a kind of embodiment, connector is buckle, bolt, screw or pin.
As a kind of embodiment, cover plate 120 or mounting base 110 arrange breach, breach is for placing wiring sheath 130.
As a kind of embodiment, in the present embodiment, cover plate 120, mounting base 110 arrange breach 124 and lower breach 114 respectively, cover plate 120 is fixed on mounting base 110, upper breach 124 is corresponding with the position of lower breach 114, upper breach 124 connects with lower breach 114, is combined to form a line outlet, for fixed placement wiring sheath 130.
As a kind of embodiment, the material of mounting base 110 is plastics.
