The utility model relates to a sealed confluence box, which comprises a confluence box body. The front face of the confluence box body is provided with a holding opening and a holding opening. The door body is connected by hinges, and the holding opening is surrounded by a sealed receiving slot, which corresponds to the position of the sealing receiving slot on the door body, surrounded by a reserved slot and reserved. The groove is provided with a sealing component whose thickness is higher than the depth of the reserved groove. Thus, an independent flat-edge sealing strip is arranged on the door body, which can fill the possible gap between the door body and the holding opening during the closing period of the door body to ensure that the sealing is closed and that no foreign matter intrudes into the door body. Sealing strip is flat-edged structure, unconventional I-shaped stacking, no fold, no skin breakage and water droplet attachment. The magnetic core is wrapped in the flat sealing strip, which can realize effective automatic adsorption and prevent misopening without door lock. The independent reserved positioning bracket is used to realize the spatial pre-planning for the subsequent installation of various components.

技术介绍
在太阳能光伏发电系统中,为了减少太阳能光伏电池阵列与逆变器之间的连线使用到汇流箱。结合多年防雷系统设计经验,研制出了多种型号汇流箱。用户可以将一定数量、规格相同的光伏电池串联起来,组成一个个光伏阵列,然后再将若干个光伏阵列并联接入光伏汇流防雷箱,在光伏防雷汇流箱内汇流后,通过控制器,直流配电柜,光伏逆变器,交流配电柜,配套使用从而构成完整的光伏发电系统,实现与市电并网。为了提高系统的可靠性和实用性,在光伏防雷汇流箱里配置了光伏专用直流防雷模块、直流熔断器和断路器等,方便用户及时准确的掌握光伏电池的工作情况,保证太阳能光伏发电系统发挥最大功效。现有汇流箱在加装门体后,门体与汇流箱本体之间存在一定的间隙,无法实现密封闭合,导致外界诸如粉尘、雨水等异物侵入,影响汇流箱本体内各类期间的正常工作与使用寿命。目前,也有一些户外汇流箱会在门体上安装密封条,但是此类密封条都是工字形堆叠,且缺乏一定的密封收纳结构。门体闭合后,会出现较为严重的密封条变形,长时间使用后会出现开裂,缩短使用寿命,影响实际的密封效果 ...
