Cellular -type low temperature terminal box

The utility model discloses a cellular -type low temperature terminal box, converges and takes room, thermal -insulated surge chamber at first diode room, second diode room, third diode room, thermal-insulated surge chamber sets up respectively between first diode room and the second diode room and between second diode room and the third diode room. A plurality of bypass diode are separated to this terminal box, have increased thermal -insulated surge chamber in the terminal box, its purpose is can slow thermal horizontal transmission speed, the safety of delay heat transfer in order to protect other diode when the diode high temperature that has damaged. 本实用新型公开了种分隔式低温接线盒，第二极管室、第二二极管室、第三二极管室、汇流带室、隔热缓冲室；所述隔热缓冲室分别设置在第二极管室与第二二极管室之间以及第二二极管室与第三二极管室之间。本接线盒把多个旁路二极管进行了分隔，在接线盒上增加了隔热缓冲室，其目的是能迟缓热量的横向传递速度，当损坏了的二极管高温时延迟热量传递以保护另外二极管的安全。
