Summary of the invention
Based on above the deficiencies in the prior art, the technical problem that the utility model solves is to provide a kind of lightning protection device, can effectively protect the safe operation of electronic equipment, avoids the existence of Leakage Current, and result is simple, and cost is low.
In order to solve the problems of the technologies described above, the utility model provides a kind of lightning protection device, comprises housing, the pole piece that powers on two of described housing top, two bottom electrode sheets in described housing, contacts with described two bottom electrode sheets and the lightning protection component between described two bottom electrode sheets; Described two power on pole piece and described two bottom electrode sheets removably connect, described shell inner surface covers one deck fireprotection layer, described fireprotection layer inside is except filling with and have fluid sealant in described two power on spaces pole piece, two bottom electrode sheets and lightning protection component, and the described two pole piece upper ends that power on are relatively set with circular arc projection.When thunderbolt occurs, high-tension electricity is relatively set with circular arc projection and is formed circular arc around electric discharge by the two pole piece upper ends that power on, and high-tension electricity is discharged rapidly; At housing, cover one deck fireprotection layer, can effectively completely cut off electric arc and leak produced high temperature and make the shell of lightning protection device unaffected, the generation of Accident prevention effectively, guarantees the safety of electronic equipment.
As the preferred implementation of technique scheme, the lightning protection device that the utility model embodiment provides further comprises the part or all of of following technical characterictic:
As the improvement of technique scheme, the spacing between circular arc projection that pole piece upper end is oppositely arranged that described two power on is 1.6-3mm.
As the improvement of technique scheme, in an embodiment of the present utility model, described lightning protection component bottom is extended with boss to both sides, and described two bottom electrode sheets are positioned on described boss.
As the improvement of technique scheme, in an embodiment of the present utility model, described housing is plastic casing.
Compared with prior art, the technical solution of the utility model has following beneficial effect:
Lightning protection device of the present utility model, by two pole pieces that power on are set on housing top, when thunderbolt occurs, high-tension electricity is relatively set with circular arc projection and is formed circular arc around electric discharge by the two pole piece upper ends that power on, and high-tension electricity is discharged rapidly; At housing, cover one deck fireprotection layer, can effectively completely cut off electric arc and leak produced high temperature and make the shell of lightning protection device unaffected, the generation of Accident prevention effectively, guarantees the safety of electronic equipment.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, below the accompanying drawing to embodiment is briefly described.
Fig. 1 is the lightning protection device structural representation of the utility model preferred embodiment.
Embodiment
Below in conjunction with accompanying drawing, describe embodiment of the present utility model in detail, it is as the part of this specification, by embodiment, principle of the present utility model is described, other aspects of the present utility model, feature and advantage thereof will become very clear by this detailed description.In the accompanying drawing of institute's reference, in different figure, same or analogous parts represent by identical drawing reference numeral.
As shown in Figure 1, for the structural representation of the lightning protection device of the utility model preferred embodiment, lightning protection device of the present utility model comprises housing 1, the pole piece 2 that powers on two of described housing 1 top, two bottom electrode sheets 3 in described housing 1, contact with described two bottom electrode sheets 3 and the lightning protection component 4 between described two bottom electrode sheets 3; Described two power on pole pieces 2 removably connect with described two bottom electrode sheets 3, and described housing 1 inner surface covers one deck fireprotection layer 5, and described fireprotection layer 5 inside are filled with and had fluid sealant except described two spaces that power on pole piece 2, two bottom electrode sheets 3 and lightning protection component 4.
Further, described two pole piece 2 upper ends that power on are relatively set with circular arc projection 21, and when thunderbolt occurs, the high voltage being produced by thunderbolt forms circular arc around electric discharge by the circular arc projection 2 being oppositely arranged, high voltage is discharged rapidly, reduce high-tension electricity and enter in housing 1.Preferred as one; two power on, and projection that pole piece 2 upper ends are oppositely arranged is circular arc; two power on, and projection that pole piece 2 upper ends are oppositely arranged can be also other shape; such as " V " type, T-shape or zigzag etc.; when thunderbolt occurs; the high voltage being produced by thunderbolt is by the V-arrangement projection the being oppositely arranged electric discharge that tapers off to a point; high voltage is discharged rapidly; do not changing under the prerequisite of essence of the present invention; only change two versions that power on the projection that pole piece 2 upper ends are oppositely arranged, also ought be interpreted as and belong to the utility model scope required for protection.
Preferably, the spacing between circular arc projection 21 that pole piece upper end is oppositely arranged that described two power on is 1.6-3mm, can guarantee so better to discharge high voltage between two circular arc projections 21, to reduce the destruction of high voltage to electronic equipment.
Further, described lightning protection component 4 bottoms are extended with boss 41 to both sides, and described two bottom electrode sheets 3 are positioned on described boss 41, and so setting prevents from entering into the impact of the high-tension electricity of housing 1 on electronic devices and components effectively.
Further, described housing 1 is plastic casing, described housing 1 inner surface covers one deck fireprotection layer 5, and plastic casing and fireprotection layer 5 can further prevent that lightning protection device is on fire, have effectively completely cut off electric arc and have leaked produced high temperature and make the plastic casing of lightning protection device unaffected.
Lightning protection device of the present utility model, by two pole pieces that power on are set on housing top, when thunderbolt occurs, high-tension electricity is relatively set with circular arc projection and is formed circular arc around electric discharge by the two pole piece upper ends that power on, and high-tension electricity is discharged rapidly; At housing, cover one deck fireprotection layer, can effectively completely cut off electric arc and leak produced high temperature and make the shell of lightning protection device unaffected, the generation of Accident prevention effectively, guarantees the safety of electronic equipment.
The above is preferred implementation of the present utility model; certainly can not limit with this interest field of the utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvement and change, these improvement and change are also considered as protection range of the present utility model.
