Abstract
The utility model relates to a modular solar module special connection box, which comprises a box cover and a box body. The modular solar module special connection box is characterized in that a shim die set is arranged in the box body, a shim of the shim die set is tightly clung with aluminum-based or copper-based coatings which are arranged on the surface of the shim, diode modules are welded, connected and fixed with the aluminum-based or copper-based coatings in a paster mode. The number of the aluminum-based or copper-based coatings is four, the aluminum-based or copper-based coatings are not connected mutually, and two ends of the diode modules are respectively and electrically connected with two neighboring aluminum-based or copper-based coatings. The number of the diode modules is three and the diode modules are arranged in series. The utility model has the advantages that the diode modules are welded, connected, and fixed with the aluminum-based or copper-based coatings in the paster mode, the structure is simple, the assembly and performance testing are convenient, and the connection box is suitable for batch production. The shim of the aluminum-based or copper-based coatings with large area has good heat dissipation performance, and after the encapsulating compound technique is adopted, the heat dissipation performance is prominent. The power stability of the component is guaranteed. Since the box body has small structure, the material cost of the box body is lowered.
Description
Technical field
The utility model relates to a kind of terminal box of solar module special use, it is characterized in that terminal box internal components modularization and with the Combination Design of aluminium base/copper base wad sheet.
Background technology
The terminal box that can be used for solar module in the market has a lot.The junction box structure design comprises diode component in lid, box body, the box body, input contact and output lead, and the solar module lead-in wire connects the input contact of terminal box, and electric current is by the output output of box body internal bypass diode through output lead.The box body of this terminal box itself is bigger than normal, and diode component is a discrete component in the box body, is connected and fixed by wire bonds.
The volume of terminal box box body own is bigger than normal, the corresponding material cost that improved, and with air as heat insulation medium, radiating effect is often bad, power loss is bigger than normal.Moreover along with the power of solar module improves constantly, the terminal box box body also can not unrestrictedly amplify.Discrete component makes the also rather inconvenience of finished product assembling Performance Detection by the mode that wire bonds is connected and fixed, and does not detect the importance of having ignored bypass diode, and that gives battery component again itself has been with potential safety hazard.
The utility model content
The purpose of this utility model is: provide that a kind of simple in structure, assembling test is convenient, the modular solar energy battery component special junction box of good heat dissipation effect.
For achieving the above object, the technical scheme of taking is: a kind of modular solar energy battery component special junction box, comprise the pad module that lid, box body and box body are built-in with, it is characterized in that: aluminium base/copper base coating that the pad of described pad module and described gasket surface are equipped with fits tightly, diode (led) module and described aluminium base/copper base coating SMD be welded to connect fixing.
Described aluminium base/copper base coating quantity is four, does not connect mutually, two ends of described diode (led) module are electrically connected with adjacent two blocks of aluminium base/copper base coating respectively.
Described diode die number of blocks is three, arranged in series.
The pad module can be connected and fixed by the buckle above the terminal box box body or screw and box body itself.Pad is common pcb board base material.
Good effect of the present utility model is: adopt diode (led) module with described aluminium base/copper base coating is SMD to be welded to connect fixingly, simple in structure, assembling, performance test are all very convenient, are fit to production in enormous quantities.Large-area aluminium base/copper coating pad has good thermal diffusivity, after the technology that adopts encapsulating, its thermal diffusivity can be more outstanding.The pressure drop of diode itself seldom when electric current passes through, can not impact the power output of assembly, has so just guaranteed the stable of component power.Also, reduced the material cost of box body because this body structure of box body is small and exquisite.
Description of drawings
The utility model is described in further detail below in conjunction with embodiment.
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A structural representation of Fig. 1.
Among the figure, 1-pad; 2-aluminium base/copper base coating; 3-diode (led) module.
Embodiment
A kind of modular solar energy battery component special junction box, comprise the pad module that lid, box body and described box body are built-in with, it is characterized in that: the pad of described pad module 1 fits tightly with aluminium base/copper base coating 2 that described pad 1 surface is equipped with, diode (led) module 3 with described aluminium base/copper base coating 2 SMD be welded to connect fixing.
Described aluminium base/copper base coating 2 quantity are four, do not connect mutually, two ends of described diode (led) module 3 are electrically connected with adjacent two blocks of aluminium base/copper base coating 2 respectively.
Described diode (led) module 3 quantity are three, arranged in series.
The pad module can be connected and fixed by the buckle above the terminal box box body or screw and box body itself.Pad is common pcb board base material.
When assembly in work time, the electric current of solar module conducts to the input contact C of terminal box box body internal gasket module through lead-in wire, through diode (led) module 3 bypasses, the electric current output procedure is finished in the output of output contact B lead.
Since be adopt diode (led) module 3 with described aluminium base/copper base coating 2 is SMD to be welded to connect fixingly, simple in structure, assembling, performance test are all very convenient, are fit to produce in enormous quantities.In the time of electric current process pad module, the diode (led) module 3 own pressure drops of adopting are very little, large-area aluminium base/copper base coating 2 has good performance of heat dissipation, and the utility model is the packaging technology that adopts encapsulating, electric current can both operate as normal under various defined terms by can the power output of pad module not being impacted.
