Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Referring to Fig.1, be a kind of thin film switch disclosed by the utility model, including set gradually from bottom to top base 1, under
Conductive layer 2, insulating layer 3, flexible arc piece 4, upper conductive layer 5 and film layer 6, wherein insulating layer 3 is opposite with flexible arc piece 4
Position offers through-hole 7.By through-hole 7, thus when pressing flexible arc piece 4, flexible arc piece 4 deformation occurs to
It is abutted against with lower conductiving layer 2.
Flexible arc piece 4 includes the minor arc portion 41 opposite with the position of through-hole 7 and the two sides opposite positioned at minor arc portion 41
Sliding part 42, sliding part 42 and minor arc portion 41 are integrally formed.In the upper surface of insulating layer 3 and the sliding part of flexible arc piece 4
42 opposite positions offer the sliding slot 31 mobile for sliding part 42, and when flexible arc piece 4 is pressurized, minor arc portion 41 is to lower conductiving layer
The movement of 2 directions deforms, and the sliding part on flexible arc piece 4 is moved along the slot bottom of sliding slot 31.In sliding slot 31
Portion is provided with limit sleeve 8, and limit sleeve 8 is fixed on the insulating layer 3, the sliding part 42 of flexible arc piece 4 pass through limit sleeve 8 and with limit
Sliding is connected between position set 8.By limit sleeve 8 to avoid the sliding part 42 of flexible arc piece 4 from deviating from from sliding slot 31.
Being provided in sliding slot 31 far from one end of through-hole 7 pushes the sliding part 42 of flexible arc piece 4 to make flexible arc
The arc spring lamination 9 that piece 4 resets, 9 one end of arc spring lamination are fixed on the one end of sliding slot 31 far from through-hole 7, and the other end is free end.Bullet
The sliding part 42 of property arc-like sheet 4 and the free end of arc spring lamination 9 abut against.The one end of sliding part 42 far from minor arc portion 41 is outside
The arc flange 421 of fold.By arc flange 421, to be sliding to offer one of sliding part 42 by arc flange 421
Dynamic portion 42 reseting elasticity mobile to the center of circle direction of through-hole 7, makes sliding part 42 be easier to be resetted.
When the minor arc portion 41 of pressing flexible arc piece 4, minor arc portion 41 deforms, to make sliding part 42 in sliding slot 31
It is mobile, and arc spring lamination 9 is squeezed with arc spring lamination 9, making arc spring lamination 9, deformation occurs.Minor arc portion 41 is applied when unclamping
The elastic force of the pressure added, arc spring lamination 9 pushes sliding part 42, resets sliding part 42 to the movement of the center of circle direction of through-hole 7,
To enable minor arc portion 41 quickly to reply the shape of free state.
Since minor arc portion 41 is squeezed deformation for a long time, the junction of minor arc portion 41 and sliding part 42 was carried out by circular arc
It crosses, to avoid minor arc portion 41 long-term depressed to cause to be broken between minor arc portion 41 and sliding part 42.
In order to enable flexible arc piece 4 preferably to abut against with lower conductiving layer 2, in the minor arc portion 41 of flexible arc piece 4
The surface of lower conductiving layer 2 is provided with contact post 411, contact post 411 and minor arc portion 41 are integrally formed.
It is internally provided with the exhaust passage 32 that through-hole 7 is connected with the external world in insulating layer 3, when pressing flexible arc piece
When 4, the air in through-hole 7 in exhaust passage 32 by being discharged, so that through-hole 7 is avoided to be in closed state, thus
Air in through-hole 7 generates resistance to flexible arc piece 4.
For the ease of pasting thin film switch on lathe, it is provided in the side surface that base 1 deviates from lower conductiving layer 2 viscous
Glue-line 10, adhesive-layer 10 are provided with tearable protective layer 101 away from a side surface of base.When needing to paste thin film switch
When on to lathe, protective layer 101 is torn from adhesive-layer 10, so that thin film switch is pasted and fixed on lathe.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this
The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical
Within novel protection scope.
