Abstract
The invention discloses a photovoltaic junction box which comprises an upper cover and a base which are bucked together. An electric conductor and an axial diode are arranged in the base, and fool-proof units are arranged between the upper cover and the base; the fool-proof units refer to a positioning block located on the upper cover and a positioning groove located in the base, the positioning block and the positioning groove are matched with each other, and the positioning grooves on the bases of the photovoltaic junction boxes of different types are different in position. The photovoltaic junction box has the advantage that the upper cover and the base are not easy to buckle wrongly during assembling.
Description
Technical field
The present invention relates to photovoltaic accessory technical field, especially relate to a kind of photovoltaic junction box.
Background technology
Photovoltaic junction box is the connector between the solar cell array and solar charging controller for electric consumption of solar module formation.As photovoltaic accessory the most conventional, its common deficiency is: be easy to when 1, upper cover and base are assembled detain mistake.Namely, terminal box has TUV certification and UL certification two type, but the upper cover of the terminal box of this two type and base just the same in profile and structure, only using unconspicuous Logo mark as differentiation, identification is difficult to, so to be easy to occur the upper cover lid of TUV to enter on UL base or UL upper cover lid to be entered the phenomenon on TUV base when production operation.2, radiating effect is bad.The axial diode mainly contained in terminal box adopts human weld usually, and scolding tin is uneven, consistency is poor, and electric conductor adopts the copper sheet of Split type structure to be then unfavorable for two kinds of reasons such as heat radiation.
Summary of the invention
The object of this invention is to provide a kind of photovoltaic junction box, it has when upper cover and base are assembled not easily detains wrong feature.Further, it also has the good feature of radiating effect.
The technical solution adopted in the present invention is: photovoltaic junction box, comprises the upper cover and base that are buckled together, and is provided with electric conductor and axial diode in this base, be provided with anti-misoperation device between described upper cover and base.
Described anti-misoperation device is be positioned at the locating piece that this covers and the location notch be positioned on this base, and this locating piece and location notch cooperatively interact, and on the base of dissimilar photovoltaic junction box, the position of location notch is different.
Described axial diode adopts SMT mode to be welded.
Described electric conductor adopts the preparation of monoblock copper sheet.
The present invention is advantageously:
1, not easily mistake is detained when upper cover and base are assembled.Photovoltaic junction box of the present invention has anti-misoperation device, thus an OLIVE BUCKLE is wrong, then namely upper cover cannot be anchored on base, effectively prevent the generation of detaining wrong phenomenon.
2, radiating effect is better.Axial diode in photovoltaic junction box of the present invention adopts SMT mode to be welded, make diode evenly and more firm be welded on conducting strip, in conjunction with being a monoblock copper sheet with electric conductor, avoiding the more and unmanageable situation of heat radiation point, ensure that the excellent radiating effect of terminal box.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is upper cover and the stereogram of base when decomposing state of the photovoltaic junction box of embodiments of the invention;
Fig. 2 is the base of the photovoltaic junction box of embodiments of the invention and the stereogram of internal part thereof.
In figure:
10, upper cover;
20, base;
30, electric conductor;
40, axial diode;
51, locating piece, 52, location notch.
Embodiment
Embodiment, is shown in shown in Fig. 1 and Fig. 2: photovoltaic junction box, comprises the upper cover 10 and base 20 that are buckled together, and is provided with electric conductor 30 in this base 20, this electric conductor 30 is welded with axial diode 40.
Further say, between this upper cover 10 and base 20, be provided with anti-misoperation device.So-called fool proof is a kind of behavior restraint means of preventing to correct, and uses the method for limiting avoiding producing mistake, allows operator does not need cost attentiveness, intuition is errorless completes correct operation also not need experience and professional knowledge to get final product.Anti-misoperation device has multiple.In the present embodiment, this anti-misoperation device is the locating piece 51 be positioned on this upper cover 10 and the location notch 52 be positioned on this base 20, and this locating piece 51 and location notch 52 cooperatively interact.That is, locating piece 51 is stuck in corresponding location notch 52 and if only if when locating piece 51 is stuck in corresponding location notch 52, can realize the fastening of upper cover 10 and base 20.And on the base 20 of dissimilar photovoltaic junction box, the position of location notch 52 is different, and on the base 20 of identical type, the position of location notch 52 is identical.That is, location notch 52 on the base 20 of the terminal box of TUV auth type is different with location notch 52 position on the base 20 of the terminal box of UL auth type, and the position being all the location notch 52 on the base 20 of the terminal box of TUV auth type is identical, the position of location notch 52 on the base 20 of the terminal box that is all TUV auth type is identical.Like this, be anchored on the base 20 of the terminal box not belonging to of the same type with it once a upper cover 10, namely locating piece 51 cannot snap in location notch 52, and namely this upper cover 10 and this base 20 cannot fasten, and then effectively prevent the generation of detaining wrong phenomenon.
Further say, this axial diode 40 adopts SMT(surface mounting technology, the abbreviation of Surface Mount Technology) mode is welded on corresponding electric conductor 30, and electric conductor 30 adopts monoblock copper sheet to prepare.Like this, by improving quality and the uniformity of welding, and avoiding the mode adopting polylith copper sheet, greatly improving the heat dispersion of this terminal box.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
