The solar photovoltaic junction box comprises an upper shell and a lower shell, and is characterized in that the lower shell is provided with a notch, a fixed plate is arranged at the notch, a bus bar, a diode and a hole type connector are arranged on the fixed plate, and the fixed plate is made of a high temperature-resisting material in an integral injection molding way, and has higher heat-conduction coefficient. In the solar photovoltaic junction box, the lower shell is designed to have a split structure by an integral injection molding mechanism; and according to the use requirements at different positions, the material with a good heat-resisting property is adopted for manufacturing the fixed plate, and a material with a high weather-resisting property is adopted for manufacturing a base body of the lower shell, so that the characteristics of the materials are fully utilized so as to solve the difficult problem in the filed of junction boxes in the prior art.
Description
Technical field
The utility model relates to photovoltaic terminal box technical field, specifically a kind of photovoltaic terminal box of longer service life.
Background technology
Solar battery component junction box is the connector between solar module and solar charging controller for electric consumption, is the cross-cutting comprehensive electric product that the design of a current collection gas, Machine Design combine with material science.The status of solar battery component junction box in the composition of solar components is extremely important, and main effect is that the electric power that solar cell produces is connected with outside line.Terminal box sticks together by the backboard of silica gel and assembly, and the lead-out wire in the assembly links together by the internal wiring in the terminal box, and internal wiring and External cable link together, and make assembly and External cable conducting.Diode is arranged in the terminal box, guarantee that assembly can operate as normal when being in the light.
Solar battery component junction box must possess following characteristic:
Shell have high anti-aging, ultraviolet-resistant capacity;
2. all connected mode employings connect the plug-in type mode soon and connect.
The present following problem of various photovoltaic terminal box ubiquities:
1, because the heating of terminal box internal body diodes make that the temperature in the box can be accumulated to 130 degrees centigrade, and common plastic casing can cause the housing thermal deformation under this temperature;
2, water resistance is poor;
3, busbar dismounting inconvenience;
Simultaneously, because terminal box is operated in outdoor, need waterproof, must make hermetic structure, and might produce instantaneous pressure in the terminal box, not allow to use exposed metal heat sink, these requirements make the temperature in the housing sharply to raise, cause the housing localized heat distortion that fits with diode, housing is come off on solar panel.Because terminal box will have equal useful life with solar panel, the life-span will reach 20 years, and the damage of terminal box may cause fatal infringement to cell panel.
The utility model content
Existing photovoltaic terminal box non-refractory high pressure, useful life are short in order to solve, the problem of waterproof effect difference and high temperature deformation, and the utility model provides a kind of safe high temperature resistant, waterproof and on-deformable photovoltaic terminal box.
The technical scheme in the invention for solving the technical problem is: this kind photovoltaic terminal box, comprise the upper shell and the lower house that can snap together, bus-bar, diode and eyelet terminal are installed in the described terminal box, it is characterized in that, has a breach on the described lower house, one fixed head is installed in indentation, there, bus-bar, diode and eyelet terminal all are installed on the fixed head, described fixed head is to adopt resistant to elevated temperatures material integrated injection molding, and has the higher coefficient of heat conduction; Lower house adopts aging-resistant material integrated injection molding, and described fixed head and lower house utilize the characteristic of different materials, and it is anti-aging high temperature resistant again making terminal box.
Described fixed head and lower house are by the buckle loose joint.
Described breach is square.
The breach next door of described lower house also is provided with the lead-in wire perforation.
Ventilated membrane with ventilative effect is set on the described upper shell.
Be respectively equipped with seal groove on the contact-making surface of described upper shell and lower house, place rubber weather strip in the described seal groove.
The beneficial effects of the utility model are: lower house is designed to split formula structure by the one injecting mechanism, instructions for use according to different parts, adopt the good material fixed head of heat resistance, the material of employing good weatherability is the lower house matrix the most, characteristics have separately been made full use of, promptly reduce cost, improved overall performance again greatly.Fixed head can not produce thermal deformation, and prolong useful life greatly, and comprehensive waterproof is effective, has solved a great problem in present terminal box field.Security performance is good, can bear the voltage of big electric current and 1000 volts, and that volume can be done again is little, and save and reduced raw-material use, be that other terminal boxes are incomparable.
Description of drawings
Fig. 1 is a upper shell front view of the present utility model;
Fig. 2 is a lower house front view of the present utility model;
Fig. 3 is a fixed head front view of the present utility model;
Among the figure: 1 upper shell, 11 air vent holes, 2 lower houses, 21 rectangular indentation, 22 first buckles, 23 bus-bar mounting grooves, 24 diode installing holes, 25 eyelet terminal installing holes, 26 lead-in wire perforation, 27 cable outlets, 3 fixed heads, 4 seal grooves.
Embodiment
As Fig. 1～shown in Figure 3,
The photovoltaic terminal box comprises upper shell 1, lower house 2, fixed head 3 three big mouldings.
Wherein, upper shell 1 adopts the injection molding of weather-proof UV resistant, at air vent hole 11 of centre design of upper shell, ventilated membrane is installed in the air-vent, a ventilated membrane protective cover is installed at ventilated membrane place in the upper shell outside, can play waterproof and ventilative double action.
Upper shell 1 and lower house 2 snap together by the bayonet socket of dual-side, and the seal groove 4 of default annular is laid sealing strip and got final product in seal groove on the contact-making surface of two housings.
Embodiment recited above is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; this area person skilled all should expand as in the determined protection range of the utility model claims various distortion of the present utility model and improvement.
