Slapper detonator ignition special transfer wire and injection molding method of lead plate thereof

Abstract

The invention discloses a slapper detonator ignition special transfer wire. The wire comprises a detonator and a lead plate and further comprises a base inlay, a two-core socket and a plug. The base inlay is detachably connected with the two-core socket, the two-core socket is connected with the plug, the two-core socket keeps the detonator and the lead plate to be vertical all the time, and the base inlay is used for keeping the lead plate horizontal when the lead plate is subjected to impact force, and the plug is communicated to the experimental socket.

Description

technical field [0001] The invention relates to the field of new electrical connectors, in particular to a special transfer wire for ignition of a shock plate detonator and an injection molding method for a lead plate thereof. Background technique [0002] The impact test of existing industrial detonators needs to be tested in a special explosion box with heat insulation and pressure insulation. During the test, the lead plate and the test support must be kept vertical, and the detonator is placed in the center of the lead plate and should be kept perpendicular to the lead plate. The ends of the foot wires are respectively connected to one end of the connecting wire. Before the test, use the detonator resistance inspection instrument to check the circuit. After confirming that it is correct, connect the ends of the connecting wire to the detonation output terminal respectively, and detonate the electric detonator. [0003] From the point of view of the ignition method, the e...

Problems solved by technology

During the entire wiring process, there is a risk of short circuit, open circuit, and voltage substandard, which will lead to unsuccessful ignition, resulting in failure of the test or failing to achieve the test effect

[0004] During the test, the detonator and the lead plate are required to maintain a high degree of verticality, but the whole set of devices cannot guarantee this point

[0005] The lead plate is required to be level during the test, and although the lead plate is placed horizontally in the whole set of devices, the lead plate is not positioned when it is impacted, so it cannot be guaranteed that the lead plate remains horizontal during the test

[0006] During the explosion process of the detonator, it is necessary to ensure that most of the energy acts on the center of the lead plate. However, in the prior art, the internal space of the detonator test explosion box is relatively large, and most of the energy of the detonator will be lost, resulting in untrue test data.

[0007] And the lead plate is extremely soft and easy to deform, and it is easy to deform under high temperature and high pressure during injection molding in the mold, resulting in unqualified products such as breakage and tilting of the lead plate after injection molding; because the surface of the lead plate is uneven and the hardness of the lead plate is very low, it cannot The use of conventional lathe lathes results in the front and rear sides being covered with PEEK material during injection molding, which makes the components unqualified
