Description
Technical field
The present invention relates to novel electric connector field more particularly to a kind of dedicated patchcord of Slapper detonator ignition and its lead
The injection moulding process of plate.
Background technique
Existing industrial detonator impact test need to be tested every in the dedicated explosion case of pressure heat-insulated, when test stereotype with
Test support need to be kept vertically, and detonator is placed on stereotype center and should be vertical with stereotype holding, and the end of detonator wire is divided
Do not connect with one end of connecting wire, meter check route is checked with detonator resistance before testing, after confirmation is errorless, by connecting wire
End be respectively connected to detonation output end, detonate electric cap.
In terms of sparking mode, existing test method is after detonator wire is connected with connecting wire, then by connecting wire from
It is connected in explosion case, is connected to priming device output end, need the on-off for checking route with inspection apparatus every time during the connection process,
To judge whether route is connected.During entire wiring, there is short circuit, open circuit in route, and voltage risk not up to standard can be led
Cause igniting unsuccessful, failure or not up to test effect so as to cause test.
Detonator and the stereotype is required to keep high perpendicular in test, and package unit not can guarantee this point.
Require stereotype horizontal in test, though and stereotype is placed horizontal in package unit, and stereotype does not have when being hit power
There is positioning, not can guarantee the level of stereotype holding during the test.
Detonator need to guarantee that energy largely acts on stereotype center in blast process, and the test of prior art detonator is quick-fried
Fried case inner space is larger, can lose most of energy of detonator, cause test data untrue.
And stereotype dead-soft, it is easily-deformable, it is easily-deformable by high temperature and pressure when being molded in mold, cause stereotype to break after injection molding
It splits, the rejected products such as inclination；Due to the uneven surface of stereotype, and stereotype hardness is very low, then can not be flat using conventional lathe vehicle,
Two sides is paved with PEEK material before and after causing in injection molding, keeps component unqualified.
Summary of the invention
The present invention overcomes the deficiencies in the prior art, a kind of embodiment are provided, it is expected soluble problem.
Above-mentioned purpose of the invention has the technical scheme that
A kind of Slapper detonator is under fire dedicated patchcord, including detonator and stereotype, which is characterized in that including pedestal inlay,
