Description
Technical field
The present invention relates to a kind of universal shock closers.
Background technology
Aircraft is emitting flight course, and sensing overload or impact acceleration need to be carried out using different types of closer, with
The next step action of aircraft is carried out, shock closer is the important of certain trigger unit and other security insurance components in aircraft
Component part is only closed in shock closer, and the trigger unit can just be made to carry out the postorder actions such as trigger action.Traditional
Shock closer only senses that the impact acceleration in front could be closed, and sensing direction scope is small, has been difficult to meet to fly
By the requirement of the environment such as lateral overbump closure when row device lands.In addition traditional shock closer often its design volume
Greatly, complicated, weight requires height greatly, to fit precision, it is difficult to meet aircraft miniaturization trend.
1) traditional omnidirectional mechanism can only be directed toward the forward direction of aircraft, flying object that can not be to rear or the left and right sides
Flying object detected, it is impossible to the flying object of rear or the left and right sides is reacted in corresponding system, it is impossible to which rear is flown
Row object carries out control survey；
2) traditional omnidirectional mechanism uses mechanical structure, and the volume of design is big, complicated, weight is big, and centre passes
Rotating ring section is more, requires height to fit precision, response characteristic is relatively low；
3) closed-loop control system is complicated, reliability is relatively low.
Invention content
In order to solve the above technical problems, the present invention provides a kind of universal shock closer, the universal shock closer energy
It realizes that certain trigger unit and other securing members are applied to the overload impact power of aircraft sensing different directions, simplifies structure, contracting
Small size and weight meet the design of aircraft miniaturization and the requirement of different directions overload impact.
The present invention is achieved by the following technical programs.
A kind of universal shock closer provided by the invention, including compression spring, inertia trigger member, ball, upper contact pin, welding
Column, lower contact pin；Compression spring is cased in the inertia trigger member, inertia trigger member bottom is fixed in compression spring lower end, inertia trigger member
Ball is laid in bottom surface, and inertia trigger member upper end is extended in the lower end of welded post, and inertia trigger member and weldering under equilibrium state
It connects column not contact, ball is in electrical contact with lower contact pin, and welding top end is electrically connected and is fixed with contact pin.
The ball is located at inertia trigger member bottom centre position.
The inertia trigger member and welded post are sleeved in insulation sleeve, in the middle part of insulation sleeve in inertia trigger member and welded post it
Between position have step-like protrusion, compression spring upper end is fixed in the step-like protrusion of insulation sleeve.
The insulation sleeve is fixed inside the shell, and ball is placed in bottom position in shell.
The top edge placement of the insulation sleeve has dielectric adhesive, and insulation sleeve is fixed on shell by dielectric adhesive.
The lower contact pin is fixed on outside the bottom end of shell.
The inertia trigger member is coaxially disposed with compression spring.
The beneficial effects of the present invention are：The work(such as direction scope is very big, impact acceleration range is wide are overloaded with inductive kick
Can, meet different use environment requirements, simple in structure, volume very little is easy for installation, light-weight, and reliability is high, is conducive to
The Miniaturization Design of aircraft.

Specific embodiment
Be described further below technical scheme of the present invention, but claimed range be not limited to it is described.
A kind of universal shock closer as shown in Figure 1, mainly by shell 1, insulation sleeve 2, compression spring 3, inertia member, ball 5,
Upper contact pin 6, dielectric adhesive 7, welded post 8 and lower contact pin 9 form.Welded post 8 is crimped on insulation sleeve 2, by ball 5, inertia
Trigger member 4,3 priority of compression spring are loaded on insulation sleeve 2 in shell 1, and riveting shell is turned in the end face that shell 1 and insulation sleeve 2 coordinate
1, insulation sleeve 2 is made to be fixed in shell 1, riveting end face to shell 1 using dielectric adhesive 7 is sealed and secure weld column 8
In 2 hole of insulation sleeve.Upper contact pin 6 is with lower contact pin 9 to being respectively welded in the bottom surface slot of the inner and outer shell 1 of 8 end face groove of welded post.
Inertia trigger member 4 and ball 5 are the components that shock closer can slide, and inertia trigger member 4 has certain set
Quality is counted, inertia trigger member 4 senses various environmental stress, further according to the drag size of compression spring 3, determines inertia trigger member 4 first
Whether slide to 8 direction of welded post, even trigger.
Contact pin 6 and lower contact pin 9 are not turned under general state, when inertia trigger member 4 is by the inertia of preceding impact
In power effect lower slider to the hole of welded post 8,4 low side ball 5 of inertia trigger member will be rotated by slight lateral force, inertia
By ball 5 indirectly with shell 1 with connecting, 4 front end of inertia trigger member is in close contact trigger member 4 with 8 endoporus of welded post so that on
Contact pin 6 and lower contact pin 9 are connected.When inertia trigger member 4 is acted on lower slider to the hole of welded post 8 by the inertia force of lateral impact
Interior, 4 low side of inertia trigger member is rotated around ball 5, the lateral inner hole wall coordinated respectively with shell 1 of inertia trigger member 4 and welding
8 inner hole wall of column is in close contact so that upper contact pin 6 and lower contact pin 9 are connected.
The mechanism of shock closer is：Under initial flight device and aircraft mechanical environment condition, compression spring is designed
Drag is more than the various stress that the welded post direction suffered by inertia trigger member is slided so that inertia trigger member cannot slide into weldering
It connects in the hole of column, ensures the safety of aircraft；When aircraft and target press scheduled orientation percussion, Inertia of design trigger member
What is be subject to rushes inertia force more than compression spring drag, and the be hit effect of power of inertia trigger member slides into position in welding post holes, upper to insert
Circuit path between needle 6 and lower contact pin 9.
It is of the invention as a result,：
1) it is simple in structure, volume very little, according to different use environments need inductive kick overload can from several g to
Hundreds of g；Impact acceleration range is big；
2) coordinated using ball sphere and inertia trigger member, can meet and be impacted by different directions, use process
In, using the installation in multiple and different directions, it can be achieved that universal impact function；
3) it is connected and designed using contact pin, installed in printed board convenient for being directly welded at, it is easy to assembly.
