Abstract
The invention discloses a cantilever type inertia switch. The cantilever type inertia switch comprises a hollow cylindrical shell, an insulating base, an electrode stem and a spherical contact, and is characterized in that the insulating base is fixed at one end of an inner cavity of the cylindrical shell, the middle part of the insulating base is provided with a through hole, one end of the electrode stem is embedded into the through hole and fixedly connected with the insulating base, the other end of the electrode stem extends outward along the axial direction thereof, passes through the through hole and is suspended at the middle part of the inner cavity of the cylindrical shell, and the electrode stem is fixedly connected with the spherical contact. The inertia switch disclosed by the invention can overcome resistance of the electrode stem under an overload action in any directions except for the axial direction so as to carry out deflection movements until being contacted with the cylindrical shell, the inertia switch is closed, and an ignition control circuit is connected. The cantilever type inertia switch has a universal closing function, thereby solving a key technology for reliably triggering a hard target against fuse under a large striking angle condition, and enabling the fuse to act reliably under various missile and target intersection conditions.
Description
Technical field
The present invention relates to the technical field of inertia switch, open in particular to a kind of beam type inertia
Close.
Background technology
Inertia switch is a kind of vitals that anti-hard goal fuse is conventional, is mainly used in identifying war
The information of pan percussion target, controls the duty of fuse the control of catch fire circuit.Work as warhead
During percussion target, inertia switch is experienced impact acceleration and is closed, and triggers or turn on the ignition of fuse
Control circuit, allows the ignition power supply charged discharge starting electric spark workpiece, completes function of detonating.
Traditional inertia switch uses spring and the design of mass, and mass is as galvanic electricity
Pole, under the effect of impact acceleration, compression spring motion, closes out until contacting with another pole
Close.But, traditional inertia switch can only realize the closure function on a direction, exists and leads
Logical threshold range width, precision are low, the deficiency of response time length.Additionally, traditional inertia switch
Be limited to the winding process level of mechanical processing technique level, particularly spring, exist volume big,
The shortcomings such as debugging cycle length, production cost are high.
Summary of the invention
Present invention aim to provide a kind of beam type inertia switch, this inertia switch profit
With beam type electrode stem as drag element, it is possible to experience the mistake of any direction in addition to axially
Carry Guan Bi, there is universal closure function, and volume is little, precision is high, fast response time, full
Foot fuse miniaturization, functionalization growth requirement.
For achieving the above object, the beam type inertia switch designed by the present invention, including hollow
Tubular shell, insulating base, electrode stem and ball, described insulating base is fixed on cylinder
One end of shape housing cavity, the middle part of described insulating base is provided with through hole, one end of described electrode stem
Embedding interior the fixing with insulating base of through hole to be connected, the other end of described electrode stem prolongs axially outward along it
Stretch and pass through hole and be suspended in the middle part of tubular shell inner chamber, and fixing with ball be connected.So,
Ball can overcome the anti-of electrode stem under the overload effect on any direction the most in addition
Masterpiece yaw motion, until contacting with cylindrical housing, inertia switch closes, and connects and gets angry
Control circuit, has universal closure function, solves anti-hard goal fuse under the conditions of the big angle of entry
The reliable key technology triggered, enables fuse reliable action under the conditions of multiple bullet mesh crosses.
Further, the first wire and the second wire, described first wire and cylindrical case are also included
The outer wall of body connects, and described second wire is connected through through hole with electrode stem.
Further, described tubular shell, electrode stem and ball are conductor.
Compared with prior art, it is an advantage of the current invention that:
One, the ball of the present invention can overload effect on any direction beyond axial
Under overcome the drag of electrode stem to make yaw motion, until contacting with cylindrical housing, inertia is opened
Close Guan Bi, connect the control of catch fire circuit, there is universal closure function, solve anti-hard goal and draw
Letter is the reliable key technology triggered under the conditions of the big angle of entry, enables fuse to cross at multiple bullet mesh
Under the conditions of reliable action.
Its two, volume of the present invention is little, light weight, adapted to fuse miniaturization, light-weighted
Exhibition trend, has a extensive future.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of a kind of beam type inertia switch；
Wherein, tubular shell 1, insulating base 2, electrode stem 3, ball 4, through hole 5,
First wire the 6, second wire 7.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail:
A kind of beam type inertia switch shown in figure, including the tubular shell 1, absolutely of hollow
Edge seat 2, electrode stem 3 and ball 4, insulating base 2 is fixed in tubular shell 1
The one end in chamber, the middle part of insulating base 2 is provided with through hole 5, and one end of electrode stem 3 embeds through hole 5
In fix with insulating base 2 and to be connected, the other end of electrode stem 3 extend axially outward along it pass logical
Hole 5 is suspended in the middle part of tubular shell 1 inner chamber, and fixing with ball 4 is connected.Cylindrical case
The maximum overall dimensions of body 1 is Φ 6mm × 14mm, and the reliable Guan Bi overload values scope of design is
110g～200g.
In technique scheme, also include the first wire 6 and the second wire 7, the first wire 6
Being connected with the outer wall of tubular shell 1, the second wire 7 is connected through through hole 5 with electrode stem 3.
Tubular shell 1, electrode stem 3 and ball 4 are conductor.
During assembling, first ball 4 is connected fixing with electrode stem 3, then by solid for electrode stem 3
It is scheduled on insulating base 2, then insulating base 2 is loaded in tubular shell 1, finally at electrode stem
The termination of 3 and the outer wall of tubular shell 1 respectively weld first wire the 6, second wire 7.
After having assembled, the most radially 0 °, 120 °, 240 ° of three directions, edge, each direction
30 ° of axial plane, 60 °, 90 °, 120 °, 150 ° of five angles be centrifuged inspection, really
Protect the centrifugal Guan Bi overload values on inertia switch all angles direction all at Guan Bi overloading threshold model
In enclosing.
Finally this inertia switch is carried out random vibration performance test radially, result display vibration
During Guan Bi, root-mean-square acceleration can reach 29g, shows that this inertia switch resistance to shock is strong, energy
Enough adaptation is similar to the relatively harsh severe trajectory environment such as Snake-wriggling maneuver, supersonic flight.
Above, the detailed description of the invention of the only present invention, it is noted that any be familiar with this area
Technical staff in disclosed technical scope, the change that can readily occur in or replacement,
All should contain within protection scope of the present invention.
