Embodiment
Refer to Fig. 1 ~ 3, the photovoltaic junction box of one embodiment of the invention, the lid (not shown) that comprise box body 1, with box body 1, coordinates, be arranged on metal terminal 3 in box body 1, be electrically connected the convergent belt (not shown) of diode 5, the cable 4 that is electrically connected at metal terminal 3 one ends and connection metal terminal 3 other ends of metal terminal 3.Metal terminal 3 has horizontally extending first surface 31, the second surface 32 be oppositely arranged with first surface 31, is connected four sides of first surface 31 and second surface 32, comprising the first side 33 and the second side 34 of being oppositely arranged with the first side 33, this metal terminal 3 also has the electrical junction 35 that extends upward to be electrically connected diode 5 from second surface 32.In this example, this metal terminal 3 is set to two, and diode 5 is set to one, and two pins of this diode 5 are electrically connected respectively two metal terminals.
Arrangement section 13 comprises from body 11 and extends upward the first support portion 131 and the second support portion 132 formed in order to support first surface, described the first support portion 131 near peristome 15, the second support portions 132 near cable trough 121.The setting of mutually staggering of this first support portion 131, the second support portion 132 and holding part 14.
At this, for the part that fixing metal terminal 3 is connected with cable 4, above-mentioned box body 1 also comprises from body 11 and extends upward and form and be positioned at the clamping part 16 of 131 both sides, the first support portion in order to clamp metal terminal 3.This clamping part 16 is close to respectively the first side 33 and the second side 34.For the ease of metal terminal 3 heat radiations, enclose and form a heat-dissipating space 17 by this first support portion 131 and clamping part 16, and, due in the present embodiment, this first support portion 131 is T-shaped structure, so this heat-dissipating space 17 is comprised of two parts simultaneously.Clamping part 16 comprise away from the section of facing directly 161 of cable trough 121 and certainly the section of facing directly 161 towards cable trough 121 near and downward-sloping slope section 162, because this slope section 162 is downward-sloping setting, therefore metal terminal 3 does not contact with clamping part 16 in this slope section 16, there is gap between the two, thereby the air in heat-dissipating space 17 can flow out from this gap, has further improved the radiating effect of heat-dissipating space 17.
Refer to Fig. 4, holding part 14 comprises the support division 141 supported on second surface 32 and the extension 142 that supports support division 141, this support division 141 comprises two the first support divisions 1411 that are oppositely arranged and the second support division 1412, extension 142 comprises respectively from body 11 and extends upward the first extension 1421 and the second extension 1422 formed in order to support respectively the first support division 1411 and the second support division 1412, this first extension 1421, the second extension 1422 is positioned on the same level line with clamping part 16, therefore the first extension 1421, the second extension 1422 also is close to respectively the first side 34 and the second side 34, also can play the purpose of auxiliary fixing metal terminal 3.
Above-mentioned the first extension 1421, the second extension 1422, the first support division 1411 and the second support division 1412 enclose the clasp chamber 143 formed in order to containing section metal terminal 3, and body 11 has 143 louvres 111 that perforation body 11 forms from described clasp chamber downwards.The metal terminal that is positioned at these louvre 111 tops partly has the first through hole 36 and the second through hole 37 that simultaneously connects first surface 31 and second surface 32, this second through hole 36 is close to electrical junction 35, by this first through hole 36 and the second through hole 37, can be convenient to box body 1 internal heat dissipating.
Above-mentioned box body 1 also comprises the holding block 18 that extends upward formation from body 11, this holding block 18 is arranged on 132 both sides, the second support portion, form the first holding block 181 and the second holding block 182, meanwhile, be formed with on metal terminal 3 with this holding block 18 and fix the fixing slot 38 coordinated, fix respectively the first fixing slot 381 and the second fixing slot 382 in the first holding block 181 and the second holding block 182, at this, this fixing slot 38 forms from the first side 33 and second side 34 indents of metal terminal, cooperation by upper holding block 18 and fixing slot 38 can prevent that metal terminal from moving forward and backward.
Although be the example purpose, the preferred embodiment of the present invention is disclosed, but those of ordinary skill in the art will recognize, in the situation that do not break away from by the disclosed scope and spirit of the present invention of appending claims, various improvement, increase and replacement are possible.
