Abstract (en)

The connector consists of a tube (12) with an inner cylinder (11) which has its cavity divided into two sections (13, 14) by a middle partition (15) and lined with a highly inflammable material (2). Two fuses (4, 5) are inserted into the cavities and held in place by end caps (3), while the inner cylinder's outer surface has a spiral groove (16) containing a slow-burning material, such as a compacted powder. The groove is connected to the two inner cavities by a hole (17, 18) at each end.
