The cable connector explosion-protection equipment of the present embodiment, its explosion-proof operation principle in use is summarized as follows：
Protected cable connector in cable connector explosion-protection equipment in the present embodiment, if it sends out in use
Raw blast, the shock wave and fragment of its generation of exploding can discharge both axially and radially, due to being hindered on axial direction by rigid mounting bracket 1
Gear, leaves behind the gap of very little in addition between the cable at cable connector two ends and the center hole 11-3 of mounting bracket 1, thus, it is quick-fried
The main radial direction to flexible structure of the fried shock wave produced and fragment discharges, and is only capable of discharging less shock wave energy on axial direction
Measure and destruction will not be produced to radially adjacent All other routes；The shock wave and fragment that blast is produced discharged in radial direction
Cheng Zhong, the shock wave energy that 5 pairs of interior protective cover 2, intervening guard cover 4 and outer protective cover are produced because cable connector explodes is played respectively
Buffering, release and the effect absorbed, while stopping the issuable fragment of blast step by step from inside to outside, so as to effectively prevent because of electricity
The harm that cable joint blast is caused to facility of the periphery including All other routes, ensures the safety of supply line.
Protected cable connector in cable connector explosion-protection equipment in the present embodiment, if occurring in use
Blast, its shock wave energy exploded is first buffered by interior protective cover 2, is let out because the buffer protection plate 21 of interior protective cover 2 is provided with
Gap between energy cushion hole 21-1, buffer protection plate 21 constitutes to let out and can buffered between slotted eye 23, buffer protection plate 21 by even
Connect spring 22 connect and interior protective cover 2 the structure design such as the elastic connection of two ends and mounting bracket 1；In the shock wave energy of blast
Under the impact of amount, the interior outside spreading of the elasticity of protective cover 2 realizes effectively buffering to the shock wave energy of blast and blast may be produced
Raw fragment is carried out first layer and stopped；
Because the energy release aperture 41-1 on the elastic construction and release protective plate 41 of intervening guard cover 4 and release are protected
Energy release slotted eye 43 grade design between plate 41, blast impulse wave energy of the intervening guard cover 4 after being buffered through interior protective cover 2
The outside spreading of the lower elasticity of impact, is discharged to the shock wave energy of blast and there may be and through interior protective cover 2 to exploding
Fragment carry out the second layer stop；
Similarly, outer protective cover 5 is due to the structure design of elastic connection between grid cover body and cover body, and outer protective cover 5 is passing through
The outside spreading of elasticity, eliminates and absorbs the shock wave of blast under the impact of the shock wave energy for the blast that intervening guard cover 4 discharges
Energy, and stop to exploding there may be and passing through the fragment of interior protective cover 2 and intervening guard cover 4 to carry out third layer.
Above example is the explanation to embodiment of the present utility model, rather than to limitation of the present utility model,
Person skilled in the relevant technique can also make various changes in the case where not departing from spirit and scope of the present utility model
Change and change and obtain corresponding equivalent technical scheme, therefore all equivalent technical schemes should be included into this practicality newly
The scope of patent protection of type.
