Description
Technical field
The utility model relates to a kind of photovoltaic cell junction box, comprises box body, is provided with plurality of conducting strips in the box body, links to each other with diode between per two adjacent conductive sheets.
Background technology
Along with the application of solar power generation is more and more general, also constantly weed out the old and bring forth the new with the closely-related photovoltaic cell junction box of its application, many groups solar module that solar power generation adopts matrix form to arrange, convert daylight to electric energy, each group solar module is connected with terminal box, and terminal box is connected with other parts of solar power system again.During terminal box work, key component diode wherein can produce heat, distributes if heat is untimely, will have influence on the life-span of terminal box.The Chinese patent publication number is 201717276 to disclose the terminal box that a kind of diode heat conduction and heat radiation is handled, its diode top is provided with the heat conduction section bar, when the diode adstante febre, heat can be transferred to the heat sink section bar of box body outer setting by the heat conduction section bar, in this way diode is carried out radiating treatment.But its shortcoming is the heat that diode produces can all be dispersed on the heat sink section bar by the heat conduction section bar, and having quite a few still to be full of in box body can't distribute.In addition, it is inside and outside that heat sink section bar and heat conduction section bar are installed at box, in case come off from box body, just can't reach the radiating effect of expection.
For this reason, the someone expects following technical scheme, is about to heat-conducting glue and is poured in the terminal box, and the heat of diode generation will distribute by heat-conducting glue like this.After adopting this structure, the diode radiating performance strengthens, but its shortcoming is a terminal box is to be fixedly installed togather with solar module, when diode damages, since the diode circumfusion heat-conducting glue, people can't take out diode in box body, terminal box can only be pulled down from solar module by force, can cause solar module impaired like this.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of photovoltaic cell junction box, not only can effectively distribute the heat that diode produces, and when diode damages, can be convenient for changing terminal box simultaneously, can not damage solar module.
For this reason, the technical solution adopted in the utility model is such: photovoltaic cell junction box, comprise box body, be provided with plurality of conducting strips in the box body, link to each other with diode between per two adjacent conductive sheets, be provided with dividing plate in the box body, box body is divided into ante-chamber and back cavity, conducting strip passes dividing plate, and an end that is connected with busbar is positioned at ante-chamber, and an end that is connected with diode is positioned at back cavity; The box body bottom of back cavity is closed, is perfused with heat-conducting glue; It also comprises a base plate, is connected under the box body by connector.
The utility model further improves, and the box body bottom of described ante-chamber has opening, and the position that described base plate is corresponding with ante-chamber also has opening.
The connected mode of base plate and box body can be to be fastened and connected by fastener, also can be to connect with bolt, can also use chute-convex tendon to connect.
The utility model further improves, and has at least four fasteners on the described base plate.
The utility model further improves, and described fastener is six, and wherein two are positioned at the base plate front end, and four are positioned at base plate rear end.
The utility model further improves, and described base plate and box body ante-chamber cooperation place have seal washer.
The utility model further improves, and described seal washer is two.
Box body of the present utility model is divided into ante-chamber and back cavity by dividing plate, and conducting strip passes dividing plate, and the conducting strip front end is positioned at ante-chamber, and the conducting strip rear end is positioned at back cavity; Do not pour into heat-conducting glue in the ante-chamber, ante-chamber mainly is provided with for connecting busbar, and the box body bottom of preferred ante-chamber has opening, can therefrom be inserted in the box body for busbar to be connected with the conducting strip front end; Be provided with diode in the back cavity, the conducting strip rear end links to each other with diode, after in back cavity, pouring into heat-conducting glue, the heat that diode produces will all be dispersed in the heat-conducting glue, utilize the heat-conducting glue good heat-conducting, be dispersed into the box body outside rapidly, adopt after this kind technical scheme, the terminal box radiating effect strengthens.Dividing plate makes heat-conducting glue can not enter ante-chamber, so busbar can not surround by heat-conducting glue, and busbar still can insert in the box body easily or take out in box body.
Because back cavity has poured into heat-conducting glue, in case the phenomenon that diode damages takes place, whole terminal box just has to remove replacing from solar module, take place for fear of this situation, the utility model comprises a base plate, the base plate fixed bonding is on battery component, and box body is fastened and connected on base plate.If diode is damaged like this, the terminal box that need more renew, the box body that only needs to have the terminal box of diode is taken down from base plate and is got final product.For more convenient use, when the box body bottom of ante-chamber has opening, also have opening at the base plate corresponding position, can make things convenient for busbar to insert in the terminal box.
With base plate and box body bottom fastening the time, base plate is provided with preferred six fasteners, and wherein two are positioned at the base plate front end, and four rear ends that are evenly distributed on base plate are arranged, and makes that like this base plate and terminal box bottom fastens, sealing effectiveness is better.
Certainly, except above-mentioned fastener connects, also can select other connected modes for use, box body is connected with base plate such as bolt connection, chute connection etc.
In addition, in order to reach better sealing effectiveness, the utility model has increased seal washer at the base plate place corresponding to box body ante-chamber position, is preferably two, makes base plate and box body in conjunction with tightr.
