Abstract
Provided is a conjunction box, mainly comprising a box body, a box cover, and a conductive chip arranged inside the box body, wherein two sides of the box body are each provided with a cable conductor coupling end. The conjunction box is characterized in that: the lower side of the box body is provided with heat radiation convex ribs via longitudinal arrangement; the cable conductor coupling ends are each externally connected with a segment of cable; the cable is provided with a cable interface; and the cable interface can be connected to different cables according to the requirements. The conjunction box of the utility model, with the installation of heat radiation convex ribs and cable interfaces, raises the heat radiation effect and cuts the manufacturing cost.
Description
Technical field
the utility model relates to and a kind of solar energy converting is become the accessory of the equipment of electric energy, is specifically related to a kind of being arranged between solar module and the power consumption equipment, is used for the terminal box that electric energy is derived.
Background technology
pollution-free, inexhaustible solar energy is more and more favored by people; Solar power generation is a kind of clean type energy resource system; Can directly utilize the luminous energy in the sunlight; It is for people to use to convert it into electric energy, almost is applicable to Anywhere---and therefore building, factory and residential building will inevitably progressively become one of necessary energy source of our daily life after the several years.
absorb daylight through settling many solar modules of arranging with matrix form; Convert thereof into electric energy, battery module is made up of a plurality of solar cell series connection, and the back side of each battery module is equipped with terminal box; By terminal box electric energy is derived through cable; Can contain the bypass diode as the bypass rectifying element in the box as required, this bypass diode is connected with the direction opposite with the output voltage of battery, so that divide the electric current of the reverse biased of galvanic battery; Draw two positive and negative electrode module stube cables by terminal box; Every stube cable is connected with adjacent battery module through cable connector; Enlarge power output with this, stube cable of each of two modules of outermost end is used to realize the electric energy output of whole solar cell group.
when solar module absorbs solar power generation work, have electric current through diode when reality is used; Make diode produce heat heat, if can not be timely and effectively with these heats derivation and lost, the accumulation of these heats; Can make the temperature of terminal box raise; If surpass the resistance to extreme temperature of device in the terminal box, will damage device and terminal box, thereby cause solar module to damage; In order to meet the use standard of the Europe and the U.S., two positive and negative electrode module stube cables of being drawn by terminal box all adopt long cable, certainly will cause the rising of manufacturing cost so simultaneously.
Summary of the invention
the utility model purpose provides a kind of terminal box, through the improvement to structure, has improved the radiating effect of terminal box, and has practiced thrift manufacturing cost.
are for achieving the above object; The technical scheme that the utility model adopts is: a kind of terminal box, mainly constitute by box body, lid and the conductive chip that is arranged in the box body, and the box body both sides are provided with the cable link; Said box body downside is vertically arranged and is provided with the heat radiation convex tendon; Said cable link is externally connected with one section cable, and said cable is provided with cable interface, and said cable interface can connect different cables according to demand.
In
technique scheme, the cable link of box body both sides connects one section cable respectively, and this cable is two authentication cables; Cable is provided with cable interface; When the actual use of terminal box,, can connect the cable of different length through cable interface in order to meet the Europe use standard different with the U.S.; Avoid all adopting long cable, and then practiced thrift cost with the same in the past.Is connected with conductive chip in the middle of the box body, said conductive chip directly contacts with box body, and the heat that produces in the electric energy transmitting process, the heat radiation convex tendon of can be directly offering through the box body downside be heat and outside air heat exchange, the function of completion derivation heat, heat radiation.
are technical scheme further; A kind of terminal box according to claim 1; It is characterized in that: said conductive chip is arranged in the box body back side; The said box body back side is provided with projection, and said conductive chip surface offers the through hole that matches with said projection, and said conductive chip is provided with diode.
even in the above-mentioned scheme, earlier diode is welded on the conductive chip, then conductive chip is installed in the box body fixing conductive chip, the part of the short circuit diode on the punching press disconnection conductive chip.
are technical scheme further, and said heat radiation convex tendon is provided with two at least.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
1, because the utility model through be provided with at least two heat radiation convex tendons at the box body downside, is arranged at the box body back side with conductive chip, make conductive chip directly contact with the convex tendon that dispels the heat; With heat and outside air heat exchange, improved radiating effect through the heat radiation projection, connected one section cable at the cable link; Cable is provided with cable interface; Thereby can connect the cable of different length, satisfy actual needs, practice thrift cost.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment one;
Fig. 2 is a conductive chip structural representation among the utility model embodiment one.
wherein: 1, box body; 2, conductive chip; 3, cable link; 4, heat radiation convex tendon; 5, cable interface; 6, through hole.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
embodiment one: referring to Fig. 1, shown in 2, a kind of terminal box mainly is made up of box body 1, lid and the conductive chip 2 that is arranged in the box body 1; Box body 1 both sides are provided with cable link 3, and said box body 1 downside is vertically arranged and is provided with at least two heat radiation convex tendons 4, and said cable link 3 is externally connected with one section cable; Said cable is provided with cable interface 5; Said cable interface can connect different cables according to demand, and said conductive chip 2 is arranged in the box body back side, and the said box body back side is provided with projection; Said conductive chip surface offers the through hole 6 that matches with said projection, and said conductive chip is provided with diode.
Standard is used according to difference when terminal box is used in reality in
, connects the cable of different length through cable interface; Avoided waste; Practiced thrift cost, conductive chip directly contacts with box body, the heat that conductive chip produces; The heat radiation convex tendon of can be directly offering through the box body downside is accomplished the function that derives heat, heat radiation with heat and outside air heat exchange.
