Below in conjunction with the accompanying drawings and embodiment to the present invention embodiment be described in detail.
As shown in figure 1, according to one embodiment of present invention, the present embodiment discloses a kind of small-sized low inductance high pressure electrical connection
Device is mainly made up of 6 parts, sees Fig. 1, and it is forced down including installing plate 1, connection ring 2, wire spring socket 3, casing 4, tail-hood 5 and height
Inductance coaxial cable 6.
Installing plate 1 is passed through using the plastics such as the polyphenylene sulfide that intensity is higher, insulating properties are preferable, be easy to injection, casing 4
The higher stainless steel and other metal materials machine of intensity, which adds, to be formed, and casing 4 is put into the liquid injected after injection mold used in installing plate 1
Body plastics cooling and solidifying forms the electric connector semi-finished product that installing plate 1 and casing 4 are fixed together.
The side wall of installing plate 1 is by the keyway of one longitudinal direction of mould formation, and width and length and the contact pin type of keyway impact piece
The key matching of detonator institute band.Jack of the bottom of installing plate 1 provided with one section of not hookup wire spring socket 3, this section of jack diameter should be able to be protected
Demonstrate,prove the insertion of Slapper detonator tape insulation sleeve portion contact pin, electric connector when length should ensure that application 5000V.1min high pressures
Air breakdown phenomenon is occurred without between two wire spring sockets.
Wire spring socket 3 is made up of copper jack and the coil spring silk of surface gold-plating, patches length and diameter should ensure that and impact
