Description
Technical field
The invention belongs to switching technique fields, more particularly, to a kind of tap switch.
Background technique
Tap switch includes moving contact and static contact, in order to guarantee the good contact between the two of moving contact and static contact,
Certain pressure can generally be applied on two movable contact spring monomers of moving contact, and then guarantee that the two contact is close.However, above-mentioned set
It sets and also brings some problems: specifically, when executing moving contact and static contact lock out operation, since static contact is by moving contact pressure
Tightly, when by rotation moving contact to cause moving contact to be detached from static contact, the abrasion between moving contact and static contact is more
Seriously, this makes the service life of tap switch big heavy discount.
Based on the above issues, also have in existing product at present by between two contacts of moving contact be arranged strut gasket it
The structure of class so that rotate moving contact when, two contacts of above-mentioned moving contact, which are softened gasket and abut against, to be opened, and at this time may be used
To substantially reduce the frictional force of moving contact and static contact when being separated from each other.
However, strutting abutted against repeatedly again such that contact is upper between two contact of gasket and moving contact in above structure
State and abut against the position degree of wear and greatly increase, this make the service life of movable contact spring remain unchanged and be difficult to keep (static contact and movable contact spring rub
Wiping is then eliminated).The above problems need urgent solution.
Summary of the invention
For the deficiencies in the prior art, the present invention provides a kind of tap switches.
The present invention is achieved through the following technical solutions: tap switch, including switch base and on the switch base turn
The handle of dynamic setting, the handle, at its lower end setting one pass through the shaft of the switch base, and one end of the shaft is connected with dynamic touching
Piece, the movable contact spring include upper and lower spaced two panels movable contact spring monomer, are provided on the rotation path of the movable contact spring
Several static contacts are provided with binding post on one end of the static contact, by rotating the shaft so that movable contact spring and institute
It states and forms connection between static contact or be detached from, a pin shaft is equipped between the two panels movable contact spring monomer, in the pin shaft
Upper end is movably set with a press spring base, a pressure spring be limited in the press spring base and positioned at upper end the movable contact spring monomer it
Between, further include that a circle is fixed setting endless glide, high undulation portion is provided in the endless glide and low undulation portion interval is set
The slide groove portion set is connected with slide bar on the press spring base, and the slide bar is slidably matched in the slide groove portion, when the static contact with
When the movable contact spring is contact on state, the slide bar is located at the low undulation portion of the slide groove portion, when the static contact and institute
State movable contact spring for separation off-state when, the slide bar is located at the high undulation portion of the slide groove portion, at this time two movable contact spring monomers it
Between open.
In above-mentioned technical proposal, the endless glide is fixedly connected with the switch base.
In above-mentioned technical proposal, the endless glide is arranged right above the pin shaft, and Open Side Down opens for slide groove portion
If.
In above-mentioned technical proposal, the endless glide is arranged in the side of the pin shaft, and the opening of slide groove portion is to level
Direction opens up.
In above-mentioned technical proposal, elastic component is provided between the two movable contact springs monomer.
The invention has the following beneficial effects: the present invention to greatly reduce the phase mutual friction between movable contact spring and static contact,
Thus substantially increase the service life of tap switch；In addition, for being not present between two contact monomer of movable contact spring in the present invention
CONTACT WITH FRICTION, therefore the defect of two contact monomer service life of movable contact spring limitation will not be generated, structure is simple, economical and practical.

Specific embodiment
Present invention is further described in detail with specific embodiment with reference to the accompanying drawing:
Embodiment 1: referring to Fig. 1 to 2, tap switch rotates the handle of setting including switch base 1 and on the switch base
2,2 lower end of the handle setting one passes through the shaft 3 of the switch base 1, and one end of the shaft 3 is connected with movable contact spring 4, described
Movable contact spring 4 includes upper and lower spaced two panels movable contact spring monomer 40, is provided on the rotation path of the movable contact spring 4 several
Static contact 5 is provided with binding post 6 on one end of the static contact 5, by rotating the shaft 3 so that movable contact spring 4 and institute
It states and forms connection between static contact 5 or be mutually disengaged.
It is equipped with a pin shaft 7 between the two panels movable contact spring monomer 40, is movably set with a pressure in 7 upper end of pin shaft
Spring abutment 70, a pressure spring 71 are limited in the press spring base 70 and between the movable contact spring monomers 40 of upper end, further excellent
Choosing, one end that pressure spring 71 is contacted with movable contact spring monomer 40 is to be fixedly connected with movable contact spring monomer, is set right above the pin shaft 7
It is equipped with the endless glide 8 that a circle is fixedly connected with the switch base 1, is provided with high undulation portion and low in the endless glide 8
The spaced slide groove portion 80 in volt portion, the slide groove portion 80 have the opening opened up downwards；70 upper end of press spring base is connected with
Slide bar 9, the slide bar 9 are slidably matched in the slide groove portion 80, when the static contact 5 is to contact conducting shape with the movable contact spring 4
When state, the slide bar 9 is located at the low undulation portion of the slide groove portion, is compressed between two movable contact spring monomers at this time；When the stationary contact
Piece 5 is when separating off-state with the movable contact spring 4, and the slide bar 9 is located at the high undulation portion of the slide groove portion, at this time two dynamic touchings
It is opened between piece monomer 40.The setting of above structure, so that movable contact spring is when slipping away the static contact, two movable contact spring monomers 40
It opens first, in this way in sliding, does not generate mutual frictional force between movable contact spring and static contact, thus substantially increase the longevity
Life.Further, since be mainly press spring base 70 by frictional force position when movable contact spring slides, and movable contact spring itself is rubbed without any
Power position is wiped, this greatly prolongs the service life of movable contact spring.
Elastic component 100 is provided between the two movable contact springs monomer 40,100 coefficient of elasticity of elastic component is less than the pressure spring 71
Coefficient of elasticity, pressure spring compress two contact monomers when, 100 forced compression of elastic component is located at the height of slide groove portion in slide bar 9
When undulation portion position, pressure spring relaxation, two movable contact spring monomers 40 can further open under the active force of elastic component 100 at this time.
Embodiment 2: referring to Fig. 3 to Fig. 4, the side of the pin shaft 7 is arranged in the endless glide 8, slide groove portion 80
It is open and is opened up to horizontal direction, the side of the press spring base 70 is arranged in the slide bar 9.Embodiment 2 remaining with embodiment 1, it is real
It applies in example 2 by opening up to horizontal direction and Slide bar structure can be made to greatly simplify the opening of slide groove portion 80.
