Abstract
The invention discloses a durable micro switch. The durable micro switch comprises a shell, an operating knob, a pull hook, a transverse spring, a normally-closed contact and a normally-open contact. A sliding groove is formed in the shell in the vertical direction, and the operating knob is vertically inserted into the sliding groove. The pull hook is installed below the operating knob and connected with the transverse spring. The transverse spring is installed on a spring slice, and one end of the spring slice is fixed to a rod body connected with the pull hook. The normally-closed contact and the normally-open contact are installed on the shell in parallel, and a contact terminal on the spring slice is located between the normally-closed contact and the normally-open contact. By means of the structure, it can be guaranteed that the operating knob can press and control the contact terminal of the spring slice to flexibly select the different contacts, the operating knob can quickly reset, the operating knob cannot be pressed excessively or dislocated, and the micro switch is more durable.
Description
Technical field
The present invention relates to field of switches, be specifically related to the durable switch of fine motion.
Background technology
Sensitive switch has small contact separation and snap-action mechanism, carries out the contact mechanism of switch action, cover with shell by the stroke of regulation and the power of regulation, there is a kind of switch of drive rod its outside, because the contact spacing of its switch is smaller, therefore named sensitive switch, is sensitive switch again.Sensitive switch automatically controls and safeguard protection etc. in the equipment needing frequent changing-over circuit; be widely used in electronic equipment, instrument and meter, mine, electric power system, household electrical appliance, electric equipment, and the military field such as space flight, aviation, naval vessel, guided missile, tank.Sensitive switch is as a kind of control element, normal needs coordinate with other elements, be switched on or switched off signal or circuit, and contact in the process of different contact for pressing operation button control spring sheet in present sensitive switch, operating knob pressing not restriction, easily presses transition, causes damage, push-button reset is comparatively slow, affects operation progress.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, there is provided fine motion durable switch, select flexibly, outside different contact, the Rapid reset of operating knob can also be realized at guarantee operating knob pressing control spring sheet contact, operating knob there will not be the situation of overvoltage or dislocation simultaneously, and device is more durable.
For solving above-mentioned technical problem, the present invention is by the following technical solutions: the durable switch of fine motion, comprise housing, operating knob, drag hook, crossed strip, normally closed interlock and normally open contact, described housing vertical direction arranges chute, and operating knob vertically inserts in chute; Described drag hook is arranged on the below of operating knob, and drag hook also connects crossed strip, and crossed strip is arranged on spring leaf, and spring leaf one end is fixed on the body of rod that is connected with drag hook; Described normally closed interlock and normally open contact are installed in parallel on housing, and the contact on spring leaf is between normally closed interlock and normally open contact.Slide in the vertical chute that operating knob can only be arranged on housing, avoid operating knob in pressing process, occur the situation that position deviation is excessive, operating knob can only be moved back and forth by the vertical direction, and operating knob is not easily because pressing excessive or misplacing and occur damaging, and device is more durable.
Vertical Spring is also installed in the bottom of described chute.Vertical Spring can limit the degree of depth that operating knob presses downwards, avoids operating knob to press amplitude downwards excessive, pulls crossed strip, make spring leaf move downward amplitude excessive, comparatively large to normally open contact pressing amplitude, causes normally open contact flexural deformation to cause damage.
The arcuate part of described drag hook is positioned at the bottom of operating knob.Handled easily controls spring leaf.
Described normally closed interlock and normally open contact all arrange the groove with spring leaf end contact matched size.Make spring leaf can better normally closed interlock or normally open contact contact.
Compared with prior art, the invention has the beneficial effects as follows:
1, slide up and down in the chute that operating knob can only be arranged on housing, can realize fast resetting, avoid operating knob position deviation in pressing process excessive, there is the situation of overvoltage or dislocation, Vertical Spring is also set in the bottom of chute and avoids operating knob to press down the excessive damage causing spring leaf or normally open contact of amplitude.
2, Vertical Spring is also installed in the bottom of chute, Vertical Spring can limit the degree of depth that operating knob presses downwards, operating knob is avoided to press amplitude downwards excessive, pull crossed strip, spring leaf is made to move downward amplitude excessive, comparatively large to normally open contact pressing amplitude, cause normally open contact flexural deformation to cause damage.
Accompanying drawing explanation
Fig. 1 is cutaway view of the present invention.
In figure, Reference numeral is expressed as: 1, housing; 2, operating knob; 3, drag hook; 4, crossed strip; 5, spring leaf; 6, normally closed interlock; 7, normally open contact; 8, chute; 9, Vertical Spring.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further elaborated, and embodiments of the invention are not limited thereto.
Embodiment 1:
As shown in Figure 1, the present invention includes housing 1, operating knob 2, drag hook 3, crossed strip 4, normally closed interlock 6 and normally open contact 7, described housing 1 vertical direction arranges chute 8, operating knob 2 vertically inserts in chute 8; Described drag hook 3 is arranged on the below of operating knob 2, and drag hook 3 also connects crossed strip 4, and crossed strip 4 is arranged on spring leaf 5, and spring leaf 5 one end is fixed on the body of rod that is connected with drag hook 3; Described normally closed interlock 6 and normally open contact 7 are installed in parallel on housing 1, and the contact on spring leaf 5 is between normally closed interlock 6 and normally open contact 7.
When external mechanical masterpiece is used for operating knob, operating knob just moves downward in chute, is stretched by crossed strip by drag hook.After certain length moved to by spring, spring leaf moves downward rapidly, and the contact of spring leaf right-hand member turns to and contacts with normally open contact below, thus the conversion of realizing circuit.If removal external force, under the effect of spring restoring force, contact is changed again instantaneously.Slide in the vertical chute that operating knob can only be arranged on housing, avoid operating knob in pressing process, occur the situation that position deviation is excessive, operating knob can only be moved back and forth by the vertical direction, and operating knob is not easily because pressing excessive or misplacing and occur damaging, and device is more durable.
Embodiment 2:
The present embodiment is preferred concrete structure on the basis of embodiment 1: Vertical Spring 9 is also installed in the bottom of chute 8.Vertical Spring can limit the degree of depth that operating knob presses downwards, avoids operating knob to press amplitude downwards excessive, pulls crossed strip, make spring leaf move downward amplitude excessive, comparatively large to normally open contact pressing amplitude, causes normally open contact flexural deformation to cause damage.
The arcuate part of described drag hook 3 is positioned at the bottom of operating knob 2.
Described normally closed interlock 6 and normally open contact 7 all arrange the groove with spring leaf 5 end contact matched size.
Just this invention can be realized as mentioned above.
