Description
Technical field
The utility model relates to a kind of terminal box, and especially a kind of solar photovoltaic assembly terminal box belongs to technical field of electric power transmission facility.
Background technology
Understand according to the applicant, the existing terminal box that is used for solar photovoltaic assembly all adopts the diode plug-in unit structure of connecting terminal in succession, its binding post is carrier with the terminal box, not only self integrated level is not high, patch inconvenience, and diode is tired easily with the place of electrical connection of splicing ear in the long-term use, influences electrical connection properties.
The utility model content
The purpose of this utility model is: at the shortcoming that above-mentioned prior art exists, propose a kind of solar photovoltaic assembly terminal box that patches conveniently, can keep the desired electrical switching performance.
In order to reach above purpose, solar photovoltaic assembly terminal box of the present utility model comprises the circuit board that is placed in the terminal box, described circuit board is a printed circuit board of assigning rectifying device, and the terminals of described printed circuit board are fixed with crimping terminal of collector belt respectively; Conduction deck and jump ring are housed in the insulation clamp hood of described crimping terminal of collector belt; Described conduction deck lining is stuck in the inwall of insulation clamp hood, and extends the overhanging end that is electrically connected with printed board from the insulation clamp hood bottom; Described jump ring is " people " font, towards a side of insulation clamp hood inwall extend on one side, have the trend that is pressed on the described conduction deck corresponding surface; The plug-in mounting lower end, upper end of described insulation clamp hood is pressed in the button on the jump ring, and a side of described button has the tape punching of confluxing of leading to described conduction deck.
During wiring, as long as push button, jump ring is bent downwardly, from perforation, inserts the band that confluxes again, release button, jump ring will be pushed down the band that confluxes, and make it and conduct electricity the reliable of deck and contact, and free-handly just can finish, and will be very convenient.And when band was confluxed in drawing, jump ring will make to conflux was with second that presses to deck more tightly, forms self-locking, thereby has guaranteed that wiring is reliable, work safety.
Of the present utility model further improving is that the box body of described terminal box is respectively equipped with at least two corresponding place's jacks with lid and is with the pin of barb.When covering lid on box body, pin inserts jack, and by the barb dual pivot locking elements, thereby guarantee good compactness, have waterproof effect.
It is that described arrangement device outside is fixed with radiator that the utility model further improves.Therefore can keep working stability, increase the service life.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the structure for amplifying schematic diagram of crimping terminal of collector belt among Fig. 1 embodiment.
Embodiment
Embodiment one
The solar photovoltaic assembly terminal box (BOX175B-03) of present embodiment as shown in Figure 1, box body 1 internal fixation of terminal box is settled printed circuit board 2, assign one group of rectifier diode 3 as rectifying device on the printed circuit board, each is put diode 3 outsides in order and is fixed with radiator 4 respectively.The terminals of printed circuit board 2 are fixed with one group of crimping terminal of collector belt 5.The box body of terminal box is respectively equipped with jack for 1 four jiaos, and the correspondence position of lid 6 is provided with the pin of band barb, but so box body and lid plug-in card sealed.7 is cables among the figure, the 8th, and connector.
Crimping terminal of collector belt as shown in Figure 2, its inside has is equipped with conduction deck 5-2 and jump ring 5-3 in the insulation clamp hood 5-1 of cavity volume.Conduction deck 5-2 lining is stuck in the inwall of insulation clamp hood 5-1, and extends the overhanging end that is electrically connected by the welding realization with printed board 2 from insulation clamp hood 5-1 bottom.Jump ring 5-3 is " people " font, constitute by the vertical edges and the inclination flanging that connect by the arc bend transition, the vertical edges vertical edges relies on first side of insulation clamp hood inwall, and with first applying of conduction deck, arc bend is hinged in insulation clamp hood by limit shaft 5-6.The inclination flanging extends towards second side of relative first side of insulation clamp hood inwall, has the trend that is pressed on second of the conduction deck 5-2.The plug-in mounting lower end, upper end of insulation clamp hood 5-2 is pressed in the button 5-5 on the jump ring inclination flanging.One side of this button has the tape punching 5-5 that confluxes that leads to second of conduction deck.
Push button is bent downwardly jump ring, and the elongated end of inclination flanging breaks away from second of deck, and put into the band that confluxes this moment from perforation, release button again, and jump ring will be pushed down the band that confluxes, and it is reliably contacted with second of deck.When upwards band was confluxed in drawing, jump ring will make to conflux was with second that presses to deck more tightly, forms self-locking.After the energising, electric current is imported crimping terminal of collector belt by busbar, through the conduction of deck, electric current is imported printed board, is exported by the diode in the printed board again.When band was confluxed in dismounting, as long as push button, the band that can will conflux was extracted out.
Evidence, the terminal box of present embodiment is closely reliable, has waterproof effect, and diode radiating is good, and contact resistance is little, and the plug-in structure of crimping terminal of collector belt makes the integrated degree height, attaching is convenient, has reduced the influence of terminal box to component power output.。
In addition to the implementation, the utility model can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of the utility model requirement.
