Jig for welding fuse

Abstract

The utility model discloses a jig for welding fuses. The jig comprises a lower template and an upper template, a welding groove matched with the fuse is formed in the lower template, and a first fixing hole is formed in the lower template; and the upper template is detachably arranged on the lower template. The elastic material pressing structure is arranged on the lower end face of the upper die plate, when the upper die plate and the lower die plate are closed, the elastic material pressing structure extends into the welding groove and abuts against the fuse, if the elastic material pressing structure abuts against the warping part of the fuse, the elastic material pressing structure can elastically deform, and therefore the fuse can be welded. When the fuse is welded, the other elastic material pressing structures are not influenced to continue to close the die downwards, so that all the elastic material pressing structures on the jig are fully pressed and contacted with the corresponding fuses, and the fuses are not displaced in the subsequent welding process under the pressing of the elastic material pressing structures, so that a worker can weld the fuses in place, and the welding efficiency is improved. And the reject ratio after the fuse is welded is effectively reduced, and even the reject ratio can be zero.
