Description
光伏组件接线盒 技术领域
本发明涉及太阳能光伏应用技术领域, 尤其涉及一种光伏组件接线 。 背景技术
随着全球能源貪源的日益枯竭, 人类寻找新的可替代型能源的步伐 也在不断加快。 太阳能是一种可再生资源。 将太阳能转化为电能既能节 约能源, 緩解供电紧张问题, 又能减少环境污染, 因此, 太阳能光伏技 术越来越受到公众的关注和青睐。 太阳能电池是由能产生光伏效应的材 料, 诸如硅、 种化镓、 硒铟铜或其他材料等制成, 从而利用光伏效应将 光能转换成电能。 目前由多片太阳能电池单元组合而成的光伏组件被大 量投入使用, 例如, 光伏组件被应用于构建发电系统, 或用于作为建筑 物的幕墙或安装于建筑物的屋顶上等。 而将光伏组件的功率输出到外部。 同时, 光伏组件接线盒也是光伏组件 做成系统的关键连接装置, 光伏组件接线盒的作用是防止光伏组件局部 被遮挡时产生热斑效果。 在光伏組件接线盒内通常包括多个功能部件, 例如用于连接光伏组件的汇流条的连接端子、 起旁路作用的二极管以及 电缆等。
在使用中, 通常需要将光伏组件接线盒固定到光伏組件上以进行能 量传输工作。 然而, 现有的光伏组件接线盒大多采用一体式制造, 即使 有少数型号是采用盒盖和盒体的构造加工, 但成形后亦采用灌胶整体密 封, 无法实现分离。 这种一体式结构的光伏组件接线盒是整体粘接在光 伏组件的背面, 因此, 在光伏组件接线盒安装到光伏組件上之后, 一旦 光伏组件接线盒在使用中出现任何故障, 例如盒内某个功能部件损坏的 话, 则此时不能轻易将光伏组件接线盒从光伏组件上拆卸下来, 需要整 体拆除光伏组件接线盒, 但这却很容易对光伏组件造成损伤, 使得整个 光伏组件无法使用 , 从而导致光伏组件接线盒的维护成本颇高。
因此, 有必要提供改进的技术方案以克服现有技术中存在的技术问 确认本
发明内容
本发明要解决的主要技术问题是提供一种光伏组件接线盒, 其便于 维护。

优选地, 所述光伏组件接线盒还包括侧向锁扣装置, 在所述第一连 接器与所述第二连接器沿预定的插接方向完成插接时, 所述侧向锁扣装 置阻止所述第一连接器与所述第二连接器沿偏离所述插接方向的方向移 动。

如图 3和图 4所示, 第一连接器 10设置接线腔 110, 第一连接端子
12延伸进入接线腔 110, 光伏组件 200的汇流条 202在接线腔 1 1 0内电 连接到第一连接端子 12。 其中, 接线腔 110包括相对的上开口 1101和 下开口 1 102 , 光伏组件 200的汇流条 202通过下开口 1102进入接线腔 110内。 第一连接器 10还包括接线腔盖 1 3 , 接线腔盖 13封盖于上开口 1 101。 优选地, 在接线腔盖 13上设置有密封介质注入孔 131及透气孔 1 32。 在光伏组件 200的汇流条 202与第一连接端子 12电连接之后, 盖 上接线腔盖 13 , 并且, 通过接线腔盖 13上的密封介质注入孔 1 31, 在接 线腔 110内填注密封介质。
如图 3和图 4所示, 第一连接器 10的第一本体 11包括基座部 11 1 及插接部 112 , 基座部 111具有固定到光伏组件 200的安装面 1110, 基 座部 111在安装面 1110上的投影的面积比插接部 112大。 插柱 1 120形 成在插接部 112。 接线腔 110连通到安装面 1110。 在基座部 111的安装 面 1110设置有容胶槽 1112 , 容胶槽 1112环绕接线腔 110设置, 并且容 胶槽 1112环绕基座部 111的周边, 基座部 111通过涂敷于容胶槽 11 1 2 内的粘结剂粘接到光伏组件 200上。优选地,基座部 111在靠近插柱 1120 的位置上设置有多个散热孔 1114 ,在第二部分 2与第一部分 1插接之后, 多个散热孔 1114对应于第二部分 2的第二本体 21的位置, 从而, 在光 伏组件接线盒 1 00的使用过程中, 可以辅助将第二部分 2内部的热量散 发掉。
在一种优选的实施方式中,如图 6和图 7所示,第二连接器 20还包 括相对于第二本体 21固定的导电基片 23 ,导电基片 23包括与第二连接 端子 22相当数量的导电区域 230 ,每个导电区域 230电连接一个第二连 接端子 22 , 例如, 第二连接端子 22可以铆接到导电区域 230。每个导电 区域 230之间设置隔断部 232 , 隔断部 232选择性地断开或短路位于其 两侧的导电区域 230, 其中被隔断部 232断开的导电区域 230之间连接 电子元件 24 , 例如, 电子元件 24可以垾接到导电区域 230。

230之间的隔断部 232、 电连接第 2根和第 3根第二连接端子 22的两个 导电区域 230之间的隔断部 232、 以及电连接第 3根和第 4根第二连接 端子 22的两个导电区域 230之间的隔断部 232均被断开,并在断开的电 连接第 1根和第 2根第二连接端子 22的两个导电区域 230之间、断开的 电连接第 2根和第 3根第二连接端子 22的两个导电区域 230之间、以及 断开的电连接第 3根和第 4根第二连接端子 22的两个导电区域 230之间 分别连接二极管 24。 然而, 图 8仅为本发明的一种示例性实施方式, 本 发明并不限于此。 根据实际光伏组件 200的大小和规格, 本发明可能并 不需要将每一个导电区域 230都断开而在被隔断部 232断开的导电区域 230之间连接电子元件 24 , 也就是说, 本发明并不需要断开每一个隔断 部 232。
在本发明的另一种实施方式中, 本发明可以几个导电区域 230为一 组, 以导电区域为单元选择性地断开, 在断开的导电区域组之间才连接 电子元件 24。 也就是说, 在一些情况下, 导电区域组内的导电区域 230 之间的隔断部 232并不需要断开。 例如, 参照图 9所示, 电连接第 1根 和第 2根第二连接端子 22的两个导电区域 230之间的隔断部 232、 以及 电连接第 2根和第 3根第二连接端子 22的两个导电区域 230之间的隔断 部 232被断开,而电连接第 3根和第 4根第二连接端子 22的两个导电区 域 230之间的隔断部 232未断开而短路位于其两侧的导电区域 230, 并 在断开的电连接第 1根和第 2根第二连接端子 22的两个导电区域 230 之间、以及断开的电连接第 2根和第 3根第二连接端子 22的两个导电区 域 230之间分别连接二极管 24。
替代地, 在本发明的又一实施方式中, 本发明也可以间隔断开隔断 部 232。 例如, 参照图 10所示, 电连接第 1根和第 2根第二连接端子 22 的两个导电区域 230之间的隔断部 232、 以及电连接第 3根和第 4根第 二连接端子 22的两个导电区域 230之间的隔断部 232被断开,而电连接 第 2根和第 3根第二连接端子 22的两个导电区域 230之间的隔断部 232 未断开而短路位于其两侧的导电区域 230, 并在断开的电连接第 1根和 第 2根第二连接端子 22的两个导电区域 230之间、以及断开的电连接第 3根和第 4根第二连接端子 22的两个导电区域 230之间分别连接 DC/AC 逆变器或者 DC/DC优化器 24。
以上结合图 8至图 10所示的描述仅为对本发明的示例性解释和说 明, 而不作为对本发明的限制, 实际上, 本发明的隔断部 232可以根据 实际需要由使用者选择性地断开或短路位于其两侧的导电区域 230, 并 在被隔断部 232断开的导电区域 230之间连接电子元件 24,从而使得本 发明的第二部分 2的内部配置更加灵活。
在本实施方式中, 每根电缆 3至少电连接一个导电区域 230, 并且, 每根电缆 3通过至少电连接一个导电区域 230, 从而实现每根电缆 3至 少电连接一个第二连接端子 22。
在一种优选的实施方式中,隔断部 232由预隔断部 2321及选择性短 路部 2322组成,预隔断部 2321是预设地切除导电基片 23而形成,选择 导电区域 2'30短路、,并且适合被选择性地切 而断开短路部 2322两侧的 导电区域 230的电连接。 优选地, 预隔断部 2321在靠近选择性短路部 2322的部位具有较大的宽度, 从而, 更加便于断开隔断部 232。
在一种优选的实施方式中, 第二部分 2还包^ ^热片 25。 在导电基 片 23上设置散热片安装部 234, 散热片 25安装到散热片安装部 234并 且与电子元件 24热接触, 从而可以将电子元件 24产生的热量及时散发 掉, 避免电子元件 24的损坏。
本发明的第二部分 2还包括绝缘基座 26, 绝缘基座 26套装在导电 基片 23的靠近第二连接端子 22的侧部上, 并且, 收容在第二本体 21 内部, 从而保证整个导电基片 23的尺寸和结构稳定性。
本发明的第二部分 2的内部结构是通过如下方式进行组装的。首先, 将第二连接端子 22压铆到导电基片 23上;其次,将二极管 24焊接到导 电基片 23的预断开的导电区域 230之间; 然后, 将绝缘基座 26从第二 连接端子 22的插接端一侧套装入, 并安装到导电基片 23的侧部上; 再 次, 将散热片 25组装到导电基片 23的散热片安装部 234上, 从而让二 极管 24能够较好的散热, 同时也能够支撑导电基片 23, 在断开隔断部 232时保护二极管 24;将预断开的导电区域 230之间的隔断部 232断开, 实现第二部分 2的内部电路;将电缆 3电连接到导电 反的导电区域 230 上; 最后, 組装上绝缘的笫二本体 21 , 从而, 完成整个第二部分 2的装 配。

优选地, 光伏组件接线盒 100还可以包括侧向锁扣装置 6 , 在第一 连接器 10与第二连接器 20沿预定的插接方向完成插接时, 侧向锁扣装 置 6阻止第一连接器 10与第二连接器 20沿偏离插接方向的方向移动。 在一种实施方式中, 侧向锁扣装置 6的锁扣方向设置成与正向锁扣装置 5的锁扣方向相互垂直, 侧向锁扣装置 6包括在第一部分 1上沿垂直于 插接方向设置的沟槽 61、 以及在第二部分 上沿垂直于插接方向设置的 锁钩 62 ,当第二部分 2与第一部分 1配合时,锁钩 62锁扣在沟槽 61中, 从而, 能够进一步防止第二部分 2在垂直于插接方向的方向上的松动, 有效确保第一连接器 10的第一连接端子 12和第二连接器 20的第二连接 端子 22的接触力度。
优选地,第一连接器 10的第一连接端子 12与第二连接器 20的第二 连接端子 22分别对称地排列, 在第二本体 21上设置有凸块 21 3, 相应 地, 在第一本体 11—上设置有凹槽 113 , 当第一连接器 10与第二连接器 20按照预定的插接方向插接时, 第二本体 21的凸块 213顺利地插入于 第一本体 11的凹槽 113中;而当第一连接器 10与第二连接器 20按照与 预定的插接方向不同的方向插接时,第二本体 21上设置的凸块 21 3会被 第一本体 11的凹槽 113以外的部分阻挡而无法完成插接,从而,通过设.
置凸块 213及其相配合的凹槽 113 , 能够有效确保第一连接器 1 0与第二 连接器 20之间的正确插接。 然而,在本发明的其他实施方式中, 也可以 在第一本体 11上设置凸块 213, 而在第二本体 21上设置凹槽 1 1 3 , 凸块 21 3与凹槽 113的配合同样可以起到防误插作用, 从而, 也能够实现本 发明的第一连接器 10与第二连接器 20之间的正确插接。

本发明的光伏组件接线盒 1 00通过将其第一部分 1与第二部分 2分 离, 从而, 企业的所有组件产品可以做成一种规格。 此外, 第二部分 2 由于生产周期短, 生产效率高, 可按订单生产, 企业避免了大批量的库 存, 而后根据市场需求, 可实施工程时再组装, 或者, 也可由企业装配 后出货。 而且, 由于是按订单生产, 可根据客户需求配固定长度的电缆 3 , 避免后电缆 3的浪费。 因此, 本发明的光伏组件接线盒 100具有较好 的灵活性和实用性, 具有广泛的市场应用前景。
以上实施方式仅用于说明本发明, 而并非对本发明的限制, 有关技 术领域的普通技术人员, 在不脱离本发明的精神和范围的情况下, 还可 以做出各种变化和变型,因此所有等同的技术方案也属于本发明的范畴, 本发明的专利保护范围应由权利要求限定。
