Temperature rise, pressure drop and the safe and reliable current interruption of point simultaneously ensure to reach service life, used either single-phase or multiphase product more
Double gap bridging contact contact structures, the bridge architecture of current most of product is flat contact mode.It is more next in power requirement
Under bigger demand, to increase the current capacity of bridge architecture, contact and bridge architecture volume can be increasing, volume increase band
The weight come make it that the moving part weight of whole product can be increasing, and this can seriously affect the ambient parameter of product, no
Higher ambient parameter (shock and vibration, directional sensitivity etc.) requirement can be met, current bridging contact contact structures are mainly
Increase the stability of bridge architecture by increasing the pressure of contact, but need bigger magnetic circuit power to drive and keep, this
It is opposite to need the demand of small power energy-saving with coil control terminal.Therefore, existing bridging contact contact structures exist volume compared with
Greatly, bridge architecture less stable, coil control terminal power are larger.
Utility model content
The purpose of this utility model is, there is provided a kind of V-type high reliability double gap bridging contact contact structures.This practicality
New structure is simple, and bridge architecture stability is higher, and the performance of anti-vibration and impact is stronger, and contact is stable, and moves
Reed, with suffering from one's own actions and from cleaning effect is wiped, has a wide range of application in V-type groove structure.
The technical solution of the utility model：A kind of V-type high reliability double gap bridging contact contact structures, including dynamic spring
Piece, movable contact spring lower section are provided with movable contact face, and movable contact face down either side is provided with one group of static contact spring piece, and static contact spring piece is provided with stationary contact
Face, pass through stationary contact face between static contact spring piece and form V-type groove structure.
In a kind of foregoing V-type high reliability double gap bridging contact contact structures, driving groove is provided with the movable contact spring,
It is provided with drive link in driving groove, is provided with overtravel above movable contact spring, the overtravel is located at drive link periphery.
A kind of foregoing V-type high reliability double gap bridging contact contact structures, in, the angle of inclination in the stationary contact face
α is 30 °.
A kind of foregoing V-type high reliability double gap bridging contact contact structures, it is characterised in that：The movable contact face with
The angle of inclination in stationary contact face is identical.
Compared with prior art, the utility model is on static contact spring piece by setting stationary contact face, makes quiet between static contact spring piece
Contact face forms V-type groove structure, makes in bridge architecture movable contact spring part by addition to contact force and frictional force, also by
The common effect of component on to stationary contact face, and set and stationary contact face angle degree identical movable contact below movable contact spring
Face, among making the V-type groove that the stationary contact face that movable contact spring is limited between static contact spring piece is formed, the stabilization of increase movable contact spring part
Property, not only improve product anti-vibration and impact performance, movable contact spring during being contacted with static contact spring piece have suffer from one's own actions in and
It is and simple in construction from wiping cleaning effect, have a wide range of application.In summary, of the present utility model simple in construction, bridge architecture is steady
Qualitative higher, the performance of anti-vibration and impact is stronger, and contact is stable, and contact resistance and pressure drop are relatively low, has and suffers from one's own actions
Neutralize from cleaning effect is wiped, have a wide range of application.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is stress diagram of the present utility model.
Mark in accompanying drawing for：1- movable contact springs, 2- movable contacts face, 3- static contact spring pieces, 4- stationary contacts face, 5- driving grooves, 6- are passed
Lever, 7- overtravels.
Embodiment
The utility model is further described with reference to the accompanying drawings and examples, but is not intended as to the utility model
The foundation of limitation.
Embodiment.A kind of V-type high reliability double gap bridging contact contact structures, as shown in figure 1, including movable contact spring 1, move
The lower section of reed 1 is provided with movable contact face 2, and the down either side of movable contact face 2 is provided with one group of static contact spring piece 3, and static contact spring piece 3 is provided with stationary contact face
4, pass through stationary contact face 4 between static contact spring piece 3 and form V-type groove structure.
Driving groove 5 is provided with the movable contact spring 1, drive link 6 is provided with driving groove 5, the top of movable contact spring 1 is provided with excess of stroke pressure
Spring 7, the overtravel 7 are located at the periphery of drive link 6；The tilt angle alpha in the stationary contact face 4 is 30 °；The movable contact face 2
It is identical with the angle of inclination in stationary contact face 4.
Stressing conditions of the present utility model are as shown in Fig. 2 movable contact face caused power on the stationary contact face that angle is α
Have：FIt is superThe pressure of=overtravel 7；F1And F2Respectively FIt is superParallel to contact plane direction and on contact plane direction
Component, f and f1The frictional force being subject to for contact.C is the armature travel L for being arranged on the lower section of drive link 6 in figureStroke, A is product
Contactor gap x and excess of stroke lThe excess of strokeSum, F in V-structure groove2For contact force, F1Component is much larger than the frictional force of contact itself,
F in the design2Contact force is the bigger the better.
Assuming that the contactor gap of product is designed as x=2mm, overtravel lThe excess of stroke=1mm, FIt is super=10N；α angles and component size
Relation and armature travel LStrokeProvide the value in special α angles as shown in Table 1 and Table 2, in table respectively with the relation of α angles,
It can be calculated by special angle angle value to show that (α is horizontal bridge when being 0 ° for influence of the α angles for contact force component and stroke
The structure of formula), so as to select suitable angle, the analysis of comprehensive angle power and the influence to stroke, α are typically chosen 30 ° or so most
To be suitable.
The relation of the α angles of table 1 and component size
The armature travel L of table 2StrokeWith the relation of α angles
