Abstract

The utility model provides an electron detonator plastics seals stopper, includes the bayonet socket stopper, the one end of bayonet socket stopper is provided with the wire, be provided with wire metal inner core in the bayonet socket stopper, be provided with the wire on the wire metal inner core and connect the long section, the wire connects the long section to be the tinned metal wire. Due to the adoption of the technical scheme, compared with the prior art, the metal wire extending out of the top end of the plastic sealing plug body of the electronic detonator is tinned, and is easy to weld with the circuit board of the electronic detonator, so that the yield is greatly improved; meanwhile, the welding part of the extension section and the lead section forms a protrusion, so that the tensile strength of the detonator plastic sealing plug is improved, the process of twisting twist of the lead before injection molding of the sealing plug can be replaced, and the tensile strength of the electronic detonator is higher.

Description

Plastic sealing plug for electronic detonator
Technical Field
The utility model belongs to the technical field of civilian blasting equipment, concretely relates to stopper is sealed to electron detonator plastics.
Background
The detonator tube plug is a plastic sealing plug and is used for being inserted into a detonator tube shell and sealing the opening part of the detonator tube shell; the existing plastic sealing plug of the electronic detonator is generally composed of a plug body and a detonator lead penetrating through the plug body; the top part of the lead extending out of the plug body is stripped to expose the split wire skin, the metal lead is welded (soldered) with an electronic circuit board of an electronic detonator, the metal lead is generally made of copper or iron, the copper metal lead is rarely used due to too high cost, a galvanized iron metal lead is adopted in most cases, but the galvanized iron lead is difficult to weld with the electronic detonator circuit board, and welding defects such as insufficient welding, false welding, sticking, copper foil tilting and the like are easy to occur. The yield in the production of the electronic detonator is reduced, and the reliability of the finished product of the electronic detonator is reduced.
Disclosure of Invention
To the technical problem, the utility model provides an electron detonator plastics seals stopper, concrete technical scheme is:
the utility model provides an electron detonator plastics seals stopper, includes the bayonet socket stopper, the one end of bayonet socket stopper is provided with the wire, be provided with wire metal inner core in the bayonet socket stopper, be provided with the wire on the wire metal inner core and connect the long section, the wire connects the long section to be the tinned metal wire.
The plastic sealing plug of the electronic detonator consists of a plug body and a detonator lead; the lead is divided into two sections, the first section is composed of a detonator lead penetrating through the tail end of the plug body and is called a lead section, and the second section is composed of two tinned metal wires extending out of the top end of the plug body and is called an extension section; the lead section leads are stripped to expose two metal leads and are communicated with the two long section tinned metal leads in a welding, riveting or crimping mode, and the like, then the two sections of leads are coated by the injection molding plug body at the joint to form the electronic detonator plastic sealing plug, and the long section tinned metal leads extend out of the top end of the plug body by a proper length and are conveniently welded with an electronic detonator circuit board.
Due to the adoption of the technical scheme, compared with the prior art, the metal wire extending out of the top end of the plastic sealing plug body of the electronic detonator is tinned, and is easy to weld with the circuit board of the electronic detonator, so that the yield is greatly improved; meanwhile, the welding part of the extension section and the lead section forms a protrusion, so that the tensile strength of the detonator plastic sealing plug is improved, the process of twisting twist of the lead before injection molding of the sealing plug can be replaced, and the tensile strength of the electronic detonator is higher.
Drawings
FIG. 1 is a schematic structural view of the present invention;
in the figure, 1-lead, 2-bayonet plug, 3-lead metal core and 4-lead extension section.
Detailed Description
As shown in fig. 1, an electronic detonator plastic sealing plug comprises a bayonet plug 2, wherein a lead 1 is arranged at one end of the bayonet plug 2, a lead metal inner core 3 is arranged in the bayonet plug 2, a lead extension section 4 is arranged on the lead metal inner core 3, and the lead extension section 4 is a tinned metal wire.
