Abstract
The utility model relates to a photonegative complementary solar energy water heater rainproof terminal box which is composed of an upper cover, a fuse box cavity body, a guard wire sleeve, etc. The utility model fundamentally solve the problem of safe use of the joint position of a connecting lead of a water heater. Because the joint position is screened by a rain terminal box, the joint position cares nothing for wind blowing, solarization and rain. The utility model not only enhance the service life, but also enhance safety performance.
Description
The utility model belongs to a kind of anti-rainwater terminal box, relates to a kind of anti-rainwater terminal box that is used on the light-electricity complementary solar water heater.
The photoelectric complementation type solar water heater is subjected to the influence of building structure and environment when mounted, and the lead that it connected will be determined mounting distance, trend and lead Len req according to height and other certain situation of floor.Therefore in process of production, need heater (or insertion heater) to be contained in the inner water tank termination and heater to be drawn lead pass outside the water tank outer end cap is suspended on, when being user installation by the time, again according to the structure in house, measured the length of required lead, fixed installation is finished after the lead trend, is connected with the outer electric heater lead of water tank more at last.Adopt the terminal place of this connected mode generally all to adopt electrician's adhesive plaster parcel, the time has been grown adhesive plaster through aging easily the coming off of exposing to the sun and rain, and exposed terminal easily causes Danger Electric shock risk.
The purpose of this utility model provides a kind of anti-rainwater terminal box, and this terminal box is used for the photoelectric complementation type solar water heater, can the terminal of electric heater be shielded and protect, thereby improved the security performance of using.
For achieving the above object, the utility model is taked following design: a kind of anti-rainwater terminal box that is used on the light-electricity complementary solar water heater, form by loam cake, safety box cavity, wire bushing etc.Described safety box cavity bottom fixedly is equipped with plural tap bolt, is fixing spring pad and nut on it; Having a protecting cap with tap bolt opposite position hole passes bolt and is fixed in the safety box cavity; From the tap bolt body that protecting cap stretched out, be installed with the metal connection post respectively; Leave the cabling space between protecting cap and safety box cavity, have wire hole on the pairing safety box cavity wall in this space; Described safety box cavity bottom center has a circular transitional pore, is with internal thread in the hole, and the bell wire bushing that this internal thread and upper end have the external screw thread boss interconnects; Described safety box cavity upper end is by the fixed connecting piece loam cake that linked closely.
The anti-rainwater terminal box of light-electricity complementary solar water heater has fundamentally solved the safe handling problem at water heater connection terminal place, because the joint is shielded by the rainwater terminal box, be not afraid of wind, Exposure to Sunlight, drench with rain, both improved useful life, improved security performance again.
The utility model is described in further detail below in conjunction with accompanying drawing.

The anti-rainwater terminal box of light-electricity complementary solar water heater is divided into three kinds on A type, Type B, C type.A type terminal box profile is designed to circle; Type B terminal box profile is designed to square or rectangle; Terminal box appearance design of C type and A type are similar, just remove the internal thread under ground strip and the wire bushing from.Why being designed to above multiple shape, is convenient use the when cooperating different electric heaters.
Following elder generation is a main embodiment with A type terminal box, specifically is illustrated.
As Fig. 1-shown in Figure 4, the anti-rainwater terminal box of light-electricity complementary solar water heater is made up of loam cake 1, safety box cavity 2, wire bushing 3 etc.Described safety box cavity 2 bottoms fixedly are equipped with three tap bolts 4, are fixed with spring pad and nut on it.Have the protecting cap 5 with opposite position hole, three tap bolt holes, pass and be bolted in the safety box cavity 2.The tap bolt body 4 that is stretched out from the protecting cap is installed with three metal connection posts 6 that can connect live wire, zero line and earth connection respectively, wherein also is mounted with one on the bolt 4 of earth connection simultaneously and extends to the outer metal ground strip 15 (as shown in Figure 7) of safety box cavity.Leave cabling space 7 between protecting cap 5 and the safety box cavity, have wire hole 8 on the pairing safety box cavity wall in this space.5 of safety box cavity bottom 9 and above-mentioned protecting caps are hollow, and this space and described cabling space 7, wire hole 8 are interconnected.Safety box cavity bottom 9 centers have a circular transitional pore 10, are with internal thread in the hole.The bell wire bushing 3 that this internal thread and upper end have external screw thread boss 11 interconnects.
Be waterproof better, described boss 11 is equipped with silicone rubber O-ring with transitional pore 10 internal thread interface places.The lower end port inner wall of described bell wire bushing 3 has the internal thread button.
At described safety box cavity 2 upper surface madial walls, be evenly distributed with boss 12 simultaneously, have tapping screw thread button 13 on it to cavity circle centre position projection.Having coincide with safety box cavity 2 with the loam cake 1 of diameter mutually with described tapping screw thread button 13 respective aperture positions 14 and with safety box cavity 2 snaps onto one.Screw is passed hole 14, and self tapping is tightened in screw buckle 13.For preventing that rainwater from bleeding in the hole seat 14, can dispose the silicone rubber seal pad at hole seat 14.
During use, the lead (live wire, zero line, ground wire) of solar-electricity heater is passed from bell wire bushing 3, and be separately fixed on the tap bolt 4 of safety box cavity 2 bottoms, with spring washer and nut that wire cover is tight, fasten, cover protecting cap 4 and loam cake 1.In the time of need installing Deng the user, can determine its conductor spacing according to building structure, take loam cake 1 apart, live wire, zero line and the earth connection of lead are attempted by on three metal connection posts 6 from the wire hole introducing respectively, buckle loam cake, with the bar screw pass hole 14 and with the screw buckle 13 of safety box cavity 2 upper surfaces, loam cake 1 can be fixed after firmly screwing, in hole 14, insert the silicone rubber seal pad afterwards.
Fig. 5 is the Type B terminal box, and this box body is square (or rectangle), and its internal structure is all consistent with A type terminal box.
Fig. 6 is a C type terminal box, this box body profile is the same with the A type all cylindrical, just removed the internal thread on ground strip 15 and the bell wire bushing 3 lower port inwalls from, and extend a step in a flat following bottom periphery, in the step end opening or end opening install a segment interface screw thread outward additional so that complement one another with insertion heater ring flange termination external screw thread or internal thread.
