Background technology
In recent years, the digital electric detonator technical development gets very fast, digital electric detonator based on technical factor design not of the same race also emerges in an endless stream, the applicant also once with regard to essential safety, the application of bio-identification aspect patent (patent name: a kind of intrinsic safety type electric detonator detonation system, application number: 200810227329.6 and patent name: a kind of digital electric detonator and initiation system based on biological identification technology, application number: 200810227330.9), satisfied certain demand in market.But at present, the bridge silk of digital electric detonator all be soldered directly to two stranded to payment to a porter together, after the energising, thereby make the heating of bridge silk reach the purpose of detonating primer.These two payment to a porter are annotated in plastic plug fixing by part, seal with detonator and connect to form detonator.But in the prior art, two payment to a porter need be screwed in together, this mode the line phenomenon may occur knocking when injection moulding, and the insulated hull burning of two payment to a porter is broken, causes two cores in the payment to a porter to bump together, thereby causes short circuit, causes the miso-fire accident; Two payment to a porter are screwed in together, and in the process of making, each operational motion is finished one, and inefficiency is unfavorable for continuous productive process, badly influences suitability for industrialized production.Because the bridge silk is at 0.01 to 0.05 millimeter, so it is welded with very high requirement,, then can cause faults such as rosin joint if weld improperly, cause detonator normally to detonate.
Detonator also is a purposes explosive the most widely in engineering explosion and the geological prospecting.Common detonator is generally metal shell, and oral area is sealed with gland, and payment to a porter is welded with scorching hot material by gland and in two payment to a porter, applies ignition charge around scorching hot material, and formations such as priming (or alms giver's medicine) and explosive are housed in its shell.In production, transportation and use because static is once being attached between payment to a porter and the Can, then ignition charge and near meeting cause spark discharge, can cause when serious that ignition charge gets angry and cause unexpected explosion.Therefore, the scope of application of plain detonator is subjected to restriction to a certain degree.Along with the development of oil, colliery, geological prospecting industry, requirement has been proposed to some extent all on antistatic property for the use of detonator.
The utility model content
For solving the shortcoming that existing technology exists, the bridging fibril welding set that the utility model provides a kind of digital electric detonator to use can weld the bridge silk easily, guarantees that two payment to a porter do not contact, and does not cause short circuit, and can play the effect of antistatic.
A kind of bridging fibril welding set for digital electronic detonator that the utility model embodiment provides comprises:
Two metal payment to a porter, medicine head, fixed block and shells; Described medicine head comprises bridge silk and the gunpowder that is coated on the bridge silk; Described two metal payment to a porter are arranged in described shell and extend to described housing exterior, the end that described two metal payment to a porter are arranged in described shell is used to weld described bridge silk, and the end that described two metal payment to a porter extend to described housing exterior is used to connect the firing circuit of digital electric detonator; Described two metal payment to a porter two ends are sheet; Described fixed block position is used for fixing described two metal payment to a porter; The groove that coincide with described fixed block shape is arranged on the inwall of described shell.
The bridging fibril welding set that is used for digital electric detonator that the utility model embodiment provides, the payment to a porter of detonator is fixed in the fixed block, have spacing between two payment to a porter in the fixed block, such two linea angulatas are arranged in parallel, and have solved two problems that line is short-circuited easily.
The beneficial effect of the existing relatively technology of the utility model is:
Adopt laminated structure by position at payment to a porter head place welded bridge silk, increased contact area, can increase substantially welding quality, the simplification production technology of bridge wire connection head and reduce the technology cost, be of value to the safety in utilization that the electrochemically resistant that improves bridge wire bond joint is learned corrosive power and product.Ultrasonic bonding requires low to the welding metal surface, oxidation or plating all can be welded; Weld interval is short, does not need any scaling powder, gas, scolder; The welding no-spark, Environmental Safety; Welding back good conductivity, the extremely low or near-zero of resistance coefficient.Fixed block and shell coating antistatic agent can play the effect of antistatic.The payment to a porter of detonator is fixed in the fixed block, has avoided the short circuit between two pieces payment to a porter.When payment to a porter and the welding of medicine head, payment to a porter is bed die not, removes repetition from toward the mould threading, directly finishes, and a plurality of operations can be finished by the machine that combines in like this, reaches the purpose of flowing water automated job.
Description of drawings
Fig. 1 is the profile that the bridging fibril welding set shell of digital electric detonator all is surrounded fixed block;
Fig. 2 is connected on the profile of metal payment to a porter place of welded bridge silk for the bridging fibril welding set shell of digital electric detonator does not surround fixed block.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
