Description
Technical field
The utility model relates to a kind of double-contact microswitch.
Background technology
Sensitive switch has small contact separation and snap-action mechanism, carries out the contact mechanism of switch motion by the stroke of regulation and the power of regulation.Masterpiece is used on action reed by actuated element by outer mechanical force, produces instantaneous operation when action reed is displaced to tie point, makes the moving contact of the end of action reed and the fixed contact quick-make of sensitive switch or disconnection.The leaf arrangement of the sensitive switch on domestic market only has pair of contact, aging along with mechanism, reed may produce warpage, loses efficacy and causes contact point loose contact, once occur that namely loose contact means that sensitive switch lost efficacy, this can reduce the useful life of sensitive switch.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of double-contact microswitch, and aging, the reed reduced because of structure lost efficacy and causes the probability of contact point loose contact, extended the useful life of sensitive switch.
For achieving the above object, the utility model adopts following technical scheme:
A kind of microswitch, comprise leaf support, reed and flexure strip, one end of flexure strip is connected on reed, the other end is formed with elastic free end, support is provided with location deck and elastic clamp seat, location deck is provided with the locating groove for blocking reed, flexure strip deck is provided with the shell fragment draw-in groove for embedding for the elastic free end of shell fragment, it is characterized in that, one end of reed arranges formation two moving contacts, reed is provided with the hollow-out parts extended towards the reed other end between two moving contacts and by one end of reed.
As a kind of preferred structure of the present utility model, during for making button pressed downwards, reed action is more level and smooth, feel is better, and reed is provided with a groove, and the position that this groove is connected with flexure strip by reed extends towards the direction away from moving contact.
Improve as one of the present utility model, flexure strip is connected to the rebate forming an arc between one end of reed and elastic free end, and hollow-out parts extends inwardly to rebate by one end of reed.
As further improvement of the utility model, hollow-out parts extends to the elastic free end of flexure strip by one end of reed.
Compared to prior art, the beneficial effects of the utility model are: do not changing in integrally-built situation, by pair of contact of the prior art is modified as two pairs of contacts, reduce because mechanism is aging, reed produces the probability that warpage inefficacy causes poor contact of contacts, as long as wherein any pair contact effectively contacts, switch can normally work, to remove after conventional flexure strip and reed beam design between bayonet socket, during button pressed downwards, reed action is more level and smooth, the better and longer service life of feel.

Wherein, 1, leaf support; 2, locating groove; 3, deck is located; 4, flexure strip deck; 5, flexure strip draw-in groove; 6, base; 7, fixed contact; 8, reed; 9, moving contact; 10, flexure strip; 11, hollow-out parts; 12, baffle plate.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further:
Fig. 1 and Fig. 2 is the structural representation of the first execution mode of double-contact microswitch, comprise leaf support 1 and reed 8, leaf support 1 is provided with location deck 3 and the flexure strip deck 4 of reed, location deck 3 and the outer ledge of flexure strip deck 4 all cave inward the reed locating groove 2 and the flexure strip draw-in groove 5 that are formed for blocking reed 8, one end of flexure strip 10 and reed 8 connect into an entirety as can be seen from Figure 1, the other end is connected in flexure strip draw-in groove 5, the other end of reed is stuck in locating groove 2, and locating groove 2 pairs of reeds 8 position.Two moving contacts 9 are provided with at the end of reed 8, relevant position on the base 6 of leaf support is also provided with two fixed contacts 7, a hollow-out parts 11 is formed between two moving contacts, have directly over two moving contacts 9 of reed 8 one piece with leaf support 1 one baffle plate 12, can limit reed 8 to top offset.
By being provided with two moving contacts 9 at reed 8 end, as long as two one of them energy normal ON of moving contact 9, sensitive switch just can normally work, and extends the useful life of sensitive switch.As shown in Figure 3, be provided with hollow-out parts 11 between two moving contacts 9, during work, external force is applied to wherein on any one moving contact, declines on the impact of another one moving contact, reduces the interlock impact between two moving contacts 9.Fig. 4 is a kind of preferred structure of reed in Fig. 3, during in order to make button pressed downwards, reed 8 action is more level and smooth, feel is better, reed is provided with a groove, the position that this groove is connected with flexure strip 10 by reed 8 extends towards the direction away from moving contact 9, increase the elasticity that two contacts 9 are respective, increase the useful life of reed 8 simultaneously.
Fig. 5 shows the structural representation of the reed 8 of the second execution mode, be that the hollow-out parts 11 on reed 8 extends to the rebate of flexure strip 10 with the difference of reed in Fig. 1, other structures do not do any change, this execution mode enhances the respective elasticity of each moving contact 9, a moving contact 9 is because the warpage of aging generation, and lost efficacy and loose contact, it can not have an impact to another moving contact 9, as long as another moving contact 9 did not also lose efficacy, switch still can normally work.
Fig. 6 shows the structural representation of the reed 8 of the third execution mode, be with the difference of Fig. 1 and Fig. 2, hollow-out parts extends to the elastic free end of flexure strip by one end of reed, that is, rebate is thoroughly into two pieces, other structures do not do any change, two moving contacts 9 are separated by present embodiment substantially completely, the elasticity that two moving contacts 9 of further enhancing are respective, reduce the interlock impact of two moving contacts 9, make the structure of reed more simple, saved material, reduce reed cost, add the useful life of reed.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection range of the utility model claim.
