According to the charging port structure for the explosion-proof lamp, one end of the charging seat is sleeved with the insulation sleeve, the charging seat and the metal casing are further bonded and fixed into one body through arranging dual components of silica gel between the charging seat and the metal casing, a bonding connection face of the charging seat and the metal casing L is greater than or equal to 10mm, so a cathode of the charging port does not directly contact with the metal casing, the explosion-proof lamp can stand a withstanding voltage test with the tolerance frequency of 50Hz+/-0.5Hz, the alternating current voltage of 500V+/-50V and the time of 60s+/-5s, a width L of the bonding connection face satisfies requirements of GB3836.1-2010 and GB3836.2-2010, and the charging port structure not only can satisfy insulation and electrical strength test requirements, but also can satisfy requirements of the explosion-proof bonding connection face.
Description
Technical field
The utility model relates to lighting device, in particular a kind of charge port structure of explosion-proof lamp.
Background technology
Light fixture mobile for doing, emergency lighting generally uses rechargeable battery (as: lithium ion battery, Ni-MH battery etc.) to do power supply to light source power supply, battery is fixed on lamp interior, all by the charge port on light fixture, with charger, to light fixture, charge, as shown in Figure 1, traditional charge port structure comprises cradle, cradle arranges positive pole 101 and negative pole 102, positive pole 101 and negative pole 102 be corresponding charge port positive pole and the charge port negative poles of forming respectively, cradle is direct and metal shell 103 is fixing, the defect that existing charge port structure exists:
1. negative pole 102 and metal shell 103 conductings, can not pass through insulation resistance and Hi-pot test.
2. this structure does not meet the requirement of GB 3836.1-2010.
3. this structure does not meet the requirement of fireman's lighting standard.
Therefore, there is defect in prior art, needs to improve.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of and can meet insulation, Hi-pot test requirement, meet again the charge port structure of explosion-proof lamp of the requirement of explosion-proof adhesive joint face.
The technical solution of the utility model is as follows: a kind of charge port structure of explosion-proof lamp, comprise metal shell and cradle, described cradle one end is nested with an insulating case, between described cradle and described metal shell, by double-component silicon layer bonding is set, is fixed as one.
Be applied to technique scheme, in described charge port structure, described cradle is welded with both positive and negative polarity wire, and charge port structural correspondence is provided with charge port positive pole and charge port negative pole, and a pressing plate is also equipped with in charge port top anodal and charge port negative pole.
Adopt such scheme, the utility model is by being nested with an insulating case in cradle one end, and, between cradle and metal shell, by being set, double-component silicon layer bonding be fixed as one, so, charge port negative pole does not directly contact with metal shell, it is 50Hz ± 0.5Hz that explosion-proof lamp can tolerate frequency, alternating voltage is 500V ± 50V, last the withstand voltage test of 60s ± 5s, adhesive joint face width degree L meets the requirement of GB 3836.1-2010 and GB 3836.2-2010, charge port structure can meet insulation, Hi-pot test requirement, meet again the requirement of explosion-proof adhesive joint face.
Accompanying drawing explanation
Fig. 1 is the cross section structure schematic diagram of prior art.
Fig. 2 is cross section structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The present embodiment provides a kind of charge port structure of explosion-proof lamp, this charge port structure is suitable for industries such as having potential explosion hazard gaseous environment 1st district, 2nd district and public security fire-fighting, railway, army, electric power, metallurgy, mine, harbour, municipal administration and does in the light fixture of movement, emergency lighting, charge port structure can meet insulation, Hi-pot test requirement, meets again the requirement of explosion-proof adhesive joint face.
As shown in Figure 2, charge port structure comprises metal shell 206 and cradle 208, on cradle 208, be welded with positive and negative electrode wire, in charge port structure, correspondence arranges charge port anodal 202 and charge port negative pole 203, one end of cradle 208 is nested with an insulating case 205, and insulating case 205 is rubber insulation sleeve, between cradle 208 and metal shell 206, by double-component silicon layer 204 bonding are set, is fixed as one, and, the adhesive joint face L207 >=10mm of double-component silicon 204.
When each parts of assembling, first rubber insulation sleeve is packed in metal shell, then just will weld, the cradle of cathode conductor packs in rubber insulation sleeve, cradle and explosion-proof lamp internal wiring are seated, after completing, toward between cradle and metal shell, pour into double-component silicon again, after solidifying, two component silica gel forms two component layer of silica gel, cradle and metal shell bonding are fixed as one, so, by rubber insulation sleeve being set in cradle one end, when assembling, can play cradle temporary fixed, and the function of insulation, and, when filling double-component silicon, can prevent that double-component silicon from entering lamp interior, affect other components and parts, so, between cradle and metal shell, with insulating case and two component layer of silica gel insulation, can meet insulation, Hi-pot test requirement, meet again the requirement of explosion-proof adhesive joint face.
Wherein, the adhesive joint face L207 >=10mm of double-component silicon layer 204, adhesive joint face width degree L meets the requirement of GB 3836.1-2010 and GB 3836.2-2010.?
The shortest path that passes through adhesive joint face from the explosion-resistant enclosure inner side of volume V to outside should be: as V≤10cm
3time, be not less than 3mm; Work as 10cm
