Fig. 1 is a kind of schematic layout pattern of contact panel shown in the exemplary embodiment of the utility model one.Such as Fig. 1 institutes
Show, the contact panel includes substrate 10, the push button 30 on substrate 10 and the NFC antenna 20 around push button 30.
Push button 30 includes main part 31 and grounding parts 32, and main part 31 is provided with the first lead 33 for being used for connecting external circuit,
Grounding parts 32 are provided with the second lead 34 for being used for connecting external circuit.
In the present embodiment, the area of substrate 10 is suitable with the side surface on wearable device, NFC antenna 20 and touch-control
Button 30 is set on the substrate 10.Wherein, NFC antenna 20 need work area it is larger, can along substrate 10 edge set with
Maximally utilizing for the space of substrate 10 is reached, to obtain the larger work area of NFC antenna 20, NFC reading/writing distance is improved.
NFC antenna 20 is loop configuration, does not have antenna distribution in the circular interior zone of substrate 10 of NFC antenna 20, can be by push button
30 are arranged in the circular space of NFC antenna, to make full use of the space of substrate 10.Wherein, push button 30 can be used certainly
Induction type capacitance touching control button.
30 points of push button is main part 31 and the two parts of grounding parts 32, and passes through the first lead 33 and the second lead respectively
34 externally connected circuits, to transmit electric signal.Wherein, the ground connection that grounding parts 32 pass through the externally connected circuit of the second lead 34
Part.30 points of push button is that main part 31 and the two parts of grounding parts 32 can reduce push button 30 to the performance of NFC antenna 20
Influence.Meanwhile, push button 30 by grounding parts 32 be grounded after, push button sensitivity can be improved, also make different product it
Between push button 30 touch-control sensitivity uniformity more preferably, realize commercialization, scale.
Receiving space 311 is provided with main part 31, grounding parts 32 are located in receiving space 311.The side of receiving space 311
Regulation space 312 is formed between the edge of edge and grounding parts 32.
The receiving space 311 set in main part 31 can be set according to the profile of main part 31, such as rectangle, circle or other
Shape.So that main part 31 have larger touch-control area, again grounding parts 32 can be made to be contained in receiving space 311.Ground connection
The area in portion 32 is less than the area of receiving space 311, the outer rim of grounding parts 32 and the edge formation regulation space of receiving space 311
312.Position in receiving space 311 is located at by regulated ground portion 32, the sensitivity of push button 30 can be adjusted.
In one embodiment, substrate 10 is in elongated rectangular shape shape, and edge of the NFC antenna 20 along substrate 10 is to center position
Winding escalator rectangular in form antenna.Main part in push button is set to rectangular-shaped, and in the region that antenna is surrounded.Touch-control
Grounding parts 32 in button 30 are rectangular plane, and long side direction of the receiving space 311 along main part 31 is set to rectangular-shaped, passes through
Spacing between regulated ground portion 32 and main part 31, adjusts the sensitivity of push button 30.
In one exemplary embodiment, main part 31 is provided with breach 313, and the edge of the main body 31 of breach 313 extends
To receiving space 311.
The structure in a ring of main part 31, breach 313 can disconnect main part 31 so that main part 31 is become by the loop closed
Into open circuit.Breach 313 can be located at any position of main part 31, be not limited to position shown in Fig. 1.Main part 31 is located at NFC antenna
In 20, electromagnetic field can be produced when NFC antenna 20 is run, the electromagnetic field to form induced potential in main part 31, then shape
Into vortex.Opened up on main part 31 after breach 313, loop of the cut-out vortex in main part 31 effectively reduces push button
The influence of 30 pairs of performances of NFC antenna 20.The spacing of breach 313 is small, does not interfere with the touch-control sensing area of push button 30, it is ensured that
Touch-control effect.
As shown in figure 1, in one exemplary embodiment, NFC antenna 20 includes an at least coil 21, to connect external electrical
3rd lead 22 on road and the 4th lead 23.The region that at least a coil 21 is surrounded forms space 211 in circle, main part 31
In in the interior space 211 of circle.Wherein, edge of at least coil 21 along substrate 10 is coiled to the center position of substrate 10 and set, extremely
The two ends of a few coil 21 are the 3rd lead 22 and the 4th lead 23.
Edge distribution of the coil 21 along substrate 10 with obtain maximum work area.Coil 21 is by a continuous linear conductor
It is coiled to form, requires that coiling forms a circle or multiturn coil according to the service behaviour of NFC antenna 20.Coiling is filamentary material one
After end is fixed, its body shrinks to form multiple nonoverlapping coil structures around a certain region pitch of the laps and gradually to center position,
Its end is free end.The shape of coil 21 can be set according to the edge shape of substrate 10, can also be set to preset shape, be such as in
Rectangular-shaped helical structure or helical form etc..Two free ends of an at least coil 21 stretch out to form the 3rd lead 22 and the 4th
Lead 23, the 3rd lead 22 and the 4th lead 23 are respectively connecting to the NFC circuit end on mainboard, to transmit signal.
After coil 21 is determined along the coiling of substrate 10 position, space 211 in circle is formed at the most inner coil of coil 21,
The shape in the space is determined by the shape of coil 21.The area in space 211 is more than the area of main part 31 in circle.Push button
30 are located in circle in space 211.
Further to reduce the main body in influence of the push button 30 to the service behaviour of NFC antenna 20, push button 30
The innermost circle of the close at least coil 21 in portion 31, and center of the center away from space 211 in circle of main part 31.That is main part 31
Positioned at the side of an at least coil 21.In one embodiment, push button 30 can be positioned close to the 3rd lead 22 and the 4th
Lead 23 is from the position of extension on an at least coil 21.
For example, main part 31 and coil 21 are set to rectangular-shaped structure.When the width that main part 31 is arranged on coil 21 is less than
When enclosing 1/2nd of interior space 211 width, then three sides of main part 31 are close to the edge of the innermost circle of coil 21, main part 31
The 4th it is outlying it is offline circle 21 center, to reduce influence of the push button 30 to the service behaviour of NFC antenna 20.
NFC antenna 20 has the 3rd lead 22 and the 4th lead 23, need to be 21 points with coil when being connected with NFC circuit end
Open, it is overlapping to avoid, and push button 30 has the first lead 33 and the second lead 34, the first lead 33 and the second lead 34 should
Avoid the lap for having beyond tie point with main part 31 or grounding parts 32.In one embodiment, can be by an at least coil 21
In the same plane with main part 31, the first lead 33 and the second lead 34, the 3rd lead 22 and the 4th lead 23 are extended to
Another plane.In another embodiment, an at least coil 21 is on not same plane with main part 31, the first lead 33 and the
Two leads 34, the 3rd lead 22 and the 4th lead 23 may be provided in another same level or Different Plane.
The contact panel can be applied to wearable device.Wearable device include equipment base, the equipment base be with
The main element of control chip or circuit board.Contact panel is arranged on equipment base, between contact panel and equipment base
Information exchange is carried out, both form a complete wearable device, such as Intelligent bracelet.The wearable device has NFC days
Line 20 can run NFC function, can also carry out other function controls by push button 30, Consumer's Experience is good.
Preferred embodiment of the present utility model is these are only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements done etc. should be included in the utility model protection
Within the scope of.
