Abstract

The invention discloses an electronic detonator bridge wire and a production method thereof. The electronic detonator bridge wire comprises a substrate and an alloy wire, wherein one surface of the substrate is an alloy wire surface and the other surface is a welding disk surface; notches are formed in two sides of the substrate; and the alloy wire penetrates through the notches and is coiled on the substrate. The alloy wire is welded on the substrate, so that a plurality of electronic detonator bridge wire combination bodies are produced and can be decomposed into single electronic detonator bridge wires. The electronic detonator bridge wire has the advantages of simple technology, high consistency, extremely small finished product size, low alloy wire damage rate and suitability for subsequent large-scale paster technology processing, is particularly suitable for paster technology processing and has a great advantage when mounted in an electronic detonator with a control chip.

Description

technical field [0001] The invention relates to an electronic detonator bridge wire monomer and a production method thereof. technical background [0002] The bridge wire monomers currently used in electronic detonators are mostly manufactured by welding or crimping alloy wires and two-legged metal brackets. It has the disadvantages of cumbersome manufacturing process, low reliability, poor consistency, easily damaged alloy wire and complicated follow-up process. In CN2864569Y, discloses a kind of new-type electric spark ignition head, and its composition comprises substrate, wire, bridge wire and ignition head, has a concave notch on the upper part of double-sided tin-plated copper clad board, and wire is made of welding block and double-sided The center of the lower two sides of the tin-plated copper-clad board is fixed, the bridge wire is placed in the upper end of the concave notch, and the two ends are respectively pasted and fixed with the surface layers of the upper ...
