Embodiment
Describe specific embodiment of the present invention below with reference to accompanying drawings in detail.Should be understood that accompanying drawing is not accurately pro rata and on the size of live width and parts, possibly is exaggerated that this only is for the convenience of explaining and clear.Further, the term that uses among this paper is through considering that its function in the present invention defines and can revising according to user or operator's custom or wish.Therefore, according to entirety presently disclosed term is defined.
Fig. 1 shows the plane graph of terminal box according to a particular embodiment of the invention; Fig. 2 shows the end view of terminal box according to a particular embodiment of the invention; Fig. 3 shows the front view of terminal box according to a particular embodiment of the invention; Fig. 4 shows diode and the plane graph of the syndeton between the radiator in the terminal box according to a particular embodiment of the invention.
Referring to Fig. 1 to 4, comprise the terminal component 50 of accepting power supply according to the terminal box of a specific embodiment, be arranged on the diode 70 of this terminal component 50; With the radiator 80 that closely contacts through die casting and diode 70.
Owing to radiator 80 closely contact with diode 70 through die casting, therefore do not need independent tightening member and can prevent diode 70 and radiator 80 between form the space, heat energy is reached from diode 70 conducts to radiator 80.
Correspondingly,, can be used for terminal box by the cheap diode that performance is low relatively because radiator 80 has improved radiating efficiency, and can be owing to diode overheated causes fault and inefficacy.
In the preparation process of radiator 80, after terminal component 50 being installed on each diode 70, the molding material that terminal component 50 and diode 70 are put into mould and will be used to form radiator 80 is injected into mould to form radiator 80.
Then, pull down mould after, solidify molding material to form and diode 70 close-connected radiators 80.
Because the radiator 80 that forms through die casting closely contacts with the positive of diode 70, the contact area between diode 70 and the radiator 80 increases, and has therefore promoted the radiating efficiency of radiator 80.
Further, be provided with a plurality of ribbon elements 30 according to the terminal box of specific embodiment, these ribbon elements 30 are connected to respectively on the terminal component 50 that diode 70 is installed.
Owing to be radiator 80 to be arranged on all diodes 70, therefore can easily radiator 80 be arranged on the terminal box through single die casting operation.
Like this, the conventional electrical connectors that radiator is connected to diode 70 is compared, can be reduced the quantity of assembly and make that the installation of radiator 80 is very easy according to the terminal box of this specific embodiment with using independent tightening member.
Further, owing to the terminal component 50 with the diode 70 that has been coupled carries out the die casting operation, so when radiator 80 closely contacts with the front of diode 70 and terminal component 50, the heat that radiator 80 absorption diodes 70 and terminal component 50 produce.Therefore, possibly realize that the more effective terminal box that prevents is overheated.
Reference numeral 12 representatives are electrically connected to the cable element 12 of terminal component 50.
Next, with describing the method for making terminal box according to a specific embodiment.
Fig. 5 shows the flow chart that a specific embodiment according to the present invention is made the method for terminal box.
Referring to Fig. 1 to 5, the method for making terminal box according to said specific embodiment comprises: diode 70 is installed on the terminal component 50 of accepting power supply (S10); Molding material is injected in the mould, and diode 70 is placed on (S20) in this mould; Pull down mould and solidify molding material (S30).
In the preparation process of radiator 80; At the base part 52 that each diode 70 is coupled to terminal component 50; So that the terminal 72 of diode 70 electrically connects after the coupling part 54 of terminal component 50; Terminal component 50 and diode 70 are put into mould and with molding material, for example alumina ceramic material is injected in the mould.
After injecting molding material,, pull down mould, solidify molding material to form the radiator 80 that closely contacts with the front of diode 70 and terminal component 50 through the predefined time.
Then, make terminal component 50 and diode 70 couplings in box 10 inside, and with in the ribbon element 30 insertion boxes 10 and through clamping element 56 ribbon element 30 being coupled to terminal component 50.
When through method for preparing radiator 80, radiator 80 is set on terminal box, through single die casting operation radiator 80 is closely linked to each other with a plurality of diodes 70.Therefore, can realize the installation of radiator than conventional electrical connectors more simply according to the method for this specific embodiment, wherein the radiator of conventional electrical connectors is to be coupled on a plurality of diodes 70 through single tightening member.
Further, because the coupling unit between terminal 72 and coupling part 54 is also surrounded by radiator 80, therefore can prevent the short circuit that loose contact therebetween causes.
Fig. 6 is the flow chart that another specific embodiment according to the present invention is made the method for terminal box.
Referring to Fig. 1 to 6, the method for making terminal box according to this specific embodiment comprises: diode 70 is installed on the terminal 50 of accepting power supply (S40); Ribbon element is assembled to each terminal component 50, and terminal component 50 and diode 70 are placed in the box 10 (S50); Molding material is injected in the box 10 (S60); Solidify molding material to form the radiator 80 (S70) that closely contacts with diode 70.
After being installed in diode 70 on the terminal component 50, terminal component 50 is placed in the box 10 and will ribbon element 30 be installed in respectively on the terminal component 50 through clamping element 56.
Then, with molding material, for example alumina ceramic material is injected in the box 10 and solidifies molding material to form the radiator 80 that closely contacts with the front of diode 70.
As described above, because independent mould is not provided, it is interior to obtain radiator 80 just molding material to be injected into box 10, can more simply radiator 80 be arranged on the terminal box than top specific embodiment.
Like this, in the terminal box according to said specific embodiment, it is overheated that radiator contacts to prevent diode with the front of diode, prevents whereby because the fault and the inefficacy of the overheated terminal box that causes of diode.
Further, in the radiator according to said specific embodiment, independent tightening member is not provided, but the positive of radiator and diode is closely contacted, reduce the quantity of parts whereby and reduce the size of terminal box through die casting.
Further, according to said specific embodiment, owing to can after diode and terminal component are assembled to box, again radiator be provided to diode, so radiator can be assembled to diode simply.
Although disclosed some specific embodiments in the present invention; But those skilled in the art is to be understood that these specific embodiments and only provides with exemplary approach; And under the situation of purport of the present invention and scope, can carry out various modifications, change and replacement.Further, the terminal box that is used for solar cell that this paper provides and the description of manufacturing approach thereof only are used for that the present invention is carried out exemplary illustration and main body of the present invention can be applied to other product.Protection scope of the present invention only is able to limit through appending claims and identity file thereof.
