Description
Technical Field
The utility model relates to an inertial switch, in particular to a missile-borne high instantaneous inertial switch.
Background
Conventional hard target warheads often employ inertial-triggered fuzes to detonate the warheads. When the warhead reaches the target area, the fuze finishes all the disarming functions and is in a waiting state, and the fuze is required to judge that the warhead contacts the target, so that a detonation signal is given.
The inertial switch is one of the components commonly used for triggering fuses, one of which is the operating state of the control circuit. The inertial switch is closed after sensing a certain overload impact generated in the carrier transmitting or collision process, and a stable electric signal is sent to the fuze, and the fuze works after receiving the signal. The inertial switch has wide requirements in the fuze, especially in the electromechanical fuze, and is an important component for the electromechanical fuze to realize the functions of triggering detonation or landing self-destruction.
The inertial switch commonly used at present adopts the design scheme of a spring and a mass block, the mass block is used as a movable electrode, and the spring is compressed to move under the action of impact overload until the inertial switch contacts with the other electrode to close the switch. However, although the conventional inertial switch can be turned on instantaneously, the action of the inertial switch has a certain delay, generally about 100ms, and the individual difference of the switch can cause inaccurate control of the closing time of the inertial switch. Therefore, the existing inertial switch triggering has the problem of time delay, and cannot meet the use requirements of high sensitivity and high instantaneous degree.
Disclosure of Invention
The utility model aims to provide a missile-borne high instantaneous inertial switch. The utility model has the characteristic of effectively reducing or even eliminating the trigger delay.
The technical scheme of the utility model is as follows: the high instantaneous inertial switch includes one casing with two electrodes, one polar cover, one mass block inside the casing, one spring over the mass block and one insulating sleeve below the mass block.
In the missile-borne high instantaneous inertial switch, the upper side and the lower side of the joint of the pole cover and the shell are provided with the insulating gaskets.
In the missile-borne high instantaneous inertial switch, the pole cover comprises a cover body, and an annular folded edge is arranged at the bottom of the cover body; the insulating gaskets are positioned on the upper side and the lower side of the annular folded edge.
In the missile-borne high instantaneous inertial switch, the mass block comprises a mass block main body, an annular bump is arranged in the middle of the mass block main body, and an arc-shaped head is arranged at the upper end of the mass block main body; the insulating sleeve is sleeved below the annular protruding block, and the spring is located above the annular protruding block.
In the above-mentioned missile-borne high instantaneous inertial switch, the shell comprises a shell body, and a step opening is arranged at an opening at the upper part of the shell body.
Compared with the prior art, the utility model controls the on-off of the two electrodes by taking the shell and the pole cover as the two electrodes of the inertial switch and controlling the action of the mass block in the shell, so that the on-off of the two electrodes can be controlled, and a switching value signal can be instantly given out after overload impact. Specifically, through the overload impact given by the system, the mass block inside the shell compresses the spring to be far away from the shell (the bottom of the mass block is not contacted with the shell) under the action of inertia force, so that two electrodes outside the switch are converted into open circuits from the channels, the whole process has high instantaneous degree, and the time delay is controlled within 1ms (no time delay is caused in theory). Meanwhile, the inertial switch has the advantage of testability. In addition, the system is simple in structure, convenient to assemble, simple to process, capable of effectively guaranteeing consistency and convenient to accurately control the system. In summary, the utility model has the characteristic of effectively reducing or even eliminating the trigger delay.

Detailed Description
The utility model is further illustrated by the following figures and examples, which are not intended to be limiting.
Examples. The high instantaneous inertial switch comprises a shell 1 and a pole cover 2 as two electrodes of the switch, wherein a mass block 3 is arranged in the shell 1, a spring 4 matched with the pole cover 2 is arranged above the mass block 3, and an insulating sleeve 5 is arranged at the lower end of the mass block 3.
Insulating gaskets 6 are arranged on the upper side and the lower side of the joint of the pole cover 2 and the shell 1.
The pole cover 2 comprises a cover body 201, and an annular folded edge 202 is arranged at the bottom of the cover body 201; the insulating spacers 6 are located on the upper and lower sides of the annular flange 202.
The mass block 3 comprises a mass block main body 301, an annular bump 302 is arranged in the middle of the mass block main body 301, and an arc-shaped head 303 is arranged at the upper end of the mass block main body 301; the insulating sleeve 5 is sleeved below the annular protruding block 302, and the spring 4 is located above the annular protruding block 302.
The shell 1 comprises a shell body 101, and a step opening 102 is formed in an opening at the upper part of the shell body 101.
The device mainly comprises a shell 1, a pole cover 2, a mass block 3, a spring 4, an insulating sleeve 5 and an insulating gasket 6.
A plurality of layers of insulating gaskets 6 are further arranged between the pole cover 2 and the shell 1, and the insulating gaskets are positioned in the area between the stepped opening and the annular folded edge; an insulating gasket 6 is also arranged above the pole cover 2.
The shell 1 and the pole cover 2 are used as two electrodes of a switch, and in an initial state, a passage is realized through mutual contact of the mass block 3 and the spring 4.
When other conditions are constant and the overload value is smaller than the design value, the inertia force of the mass block 3 is smaller than the elastic force of the spring 4, the mass block 3 cannot act, and at the moment, the two electrodes of the switch are always kept in an initial state and are in a passage state. When the overload value reaches the design value, the inertia force of the mass block 3 is larger than the elastic force of the spring 4, the mass block 3 compresses the spring, the contact with the shell 1 is released, and the two electrodes of the switch are converted into open circuits from the passage.
The insulating sleeve 5 and the insulating spacer 6 ensure that the internal contact is not short-circuited when the inertial switch is in an operating state, and the open (i.e. disconnected) state is always maintained.
The inertial switch can be in a working state in a continuous overload period, and when the overload is small, the mass block 3 can be restored to the initial position under the action of the elastic force of the spring 4 to realize the reset, so that the testability of the utility model is realized.
The switch function can be realized by adjusting the weight of the mass block 3 and the elasticity of the spring 4 and matching different inertial impact forces, so that the device is suitable for various ammunition fuses and has wide application prospect and practical value.
