Abstract
The utility model relates to a leading fuse with a safety switch used for mines, laying roads, city directional blasting and other harsh environments. The fuse with a safety switch is composed of a detonator socket 1, a working head 2 and lead wire cables 3 connected with each other in turn. The energy of a control fuse and the leading fuse can be strictly separated, and detonation can happen via the simultaneous action of controlling and detonating voltage. The utility model has high safety, small size, light weight, high-temperature resistance and high-voltage resistance without any influence from stray electronic charges and mechanical friction in use.
Description
The utility model relates to the cap sensitive system, particularly because a kind of safety switch fuse of adverse circumstances such as oil, mine, open circuit, city directional blasting.
Existing fuse does not have safeguard protection mostly, resembles the more frequent impact type fuze system of using, and is bulky, costs an arm and a leg; And be easy to jam, ignite so that can not fuse get angry, on-the-spot stray voltage, energy, static can cause the mistake letter at any time, and control letter and fuse energy can not strictly separate, make the on-the-spot fuze system that uses very dangerous, and all have only mostly at normal temperatures and use.The purpose of this utility model is to provide a kind of safety switch fuse that control letter and the strictness of fuse energy are separated.
The utility model by detonator socket 1, worker bow 2, lead-in cables 3 forms, detonator socket 1 is positioned at the end of switch fuse, and links to each other with working head 2, lead-in cables 3 links to each other with working head 2.Working head 2 is equipped with 5 spring hole scokets, and wherein middle is the shielded lead hole, and each two hole internal communication of both sides are plugged in the detonator lead-in wire respectively.
Advantage of the present utility model is more can adapt to adverse circumstances compared with similar products; but in HTHP place also operate as normal; control, ignition voltage are done the time spent simultaneously and just can be ignited; before ignition; circuit is with the whole shielding protections of detonator; and ground connection, be not subjected to the influence of any spuious electric charge, mechanical friction in the use, thereby be safe and reliable.And volume is little, in light weight.
Fig. 1 is the utility model schematic diagram.
Fig. 2 is a circuit controling drawing
Fig. 3 is a detonator socket schematic diagram
Below in conjunction with accompanying drawing the utility model is further specified:
As shown in the figure, detonator socket 1 is positioned at the end of switch fuse, and link to each other with working head 2, lead-in cables 3 links to each other with working head 2, and the outside of switch fuse is surrounded by exotic material, operate portions 2 has microelectronic circuits, working head 2 is equipped with 5 spring hole scokets, and wherein, the centre is the shielded lead hole, each two hole internal communication of both sides are plugged in the detonator lead-in wire respectively; Lead-in cables 3 inside have two lines to be the input of control voltage, and two lines are for igniting the voltage input, and one is the bonding line.
Use of the present utility model divides two-stage, and one-level amount high temperature can reach 90 ℃, and secondary amount high temperature can reach 130 ℃.
