Description

轴向二极管接线盒及其制造方法 技术领域
本发明涉及光伏接线盒技术领域，尤其涉及一种轴向二极管接线盒及其制造方法。
背景技术
随着太阳能发电的应用越来越普遍，与其应用密切相关的接线盒也不断推陈出新，太阳能发电采用矩阵形式排列的多组太阳能电池模块，将日光转换成电能，每一组太阳能电池模块与接线盒相连接，接线盒再与太阳能发电系统的其他部分相连接。
二极管是光伏电池接线盒中的关键组件，在使用过程中，二级管会产生热量，如果这些热量不及时散发出去，会影响到二极管的寿命，同时不能满足电气安全要求。并且，随着市场对大电流光伏接线盒需求加大，由于普通轴向二极管无法满足大电流需求，越来越多的厂商使用模块二极管代替轴向二极管，但是，模块二极管的使用需要新增模块二极管封装测试的相关设备，设备成本较高且测试周期较长。大电流应用的模块二极管生产工序复杂且产品造价高。
发明内容
