Abstract

The invention discloses a double-branch cable for an electronic blasting system, and a mold, and relates to the technical field of cables. The cable comprise a conductor, an insulating part and a connecting part. The strength of the cable is improved through the tensile property of the high-strength alloy conductor, the wear resistance of the cable is improved through the insulating part and the connecting part which are made of wear-resistant materials and made of insulating materials, and the problem that in the laying process, a blasting system fails and even mistaken blasting occurs in advance due to damage of pulling and dragging to the cable is solved. Moreover, the situations of overlong distance and complex wiring in the actual use process of the digital electronic detonator are avoided. By changing the structure of the cable, the connecting part is added on the basis of the insulating part, a longitudinal water-blocking type connection double-parallel structure is formed through a high-pressure extrusion process, and meanwhile, an antistatic agent is further coated, so that the adhesive force between the conductor and the insulating part is improved, the longitudinal water-blocking performance is ensured, and the antistatic property is enhanced; and the connected double-parallel structure also solves the problems of knotting, twisting and entanglement and the like of the conventional twisted pair in the wiring process.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a double-branch cable used in an electronic blasting system. Background technique [0002] The traditional detonator blasting line is a twisted pair produced by simple copper core or steel core and ordinary plastic insulation material. The material factor limits the tensile strength of the cable, and the line will be damaged due to friction during construction and dragging. The uneven distribution of electric charge on the surface of the cable leads to the accumulation of static electricity. After reaching a certain intensity, there will be a danger of accidental explosion, which threatens the safety of buildings and personal property. [0003] And the cable structure used by the traditional electric detonator is that after the outer layer of the low-strength metal conductor is extruded and insulated, two insulated wires are twisted into strands, and then directly connected to the...
