The contact point 21 connect, the distance of the contact point to first side is 1/4 λ ± 40 millimeter.That is, contact point 21 is set
In second in 132 or/and third while 133 on at the position of the distance for 1/4 λ ± 40 millimeter on first side 131, it is and described
Second at 132 or/and third 133 on partly do not set again between the contact point 21 and first side 131 with
The contact point that mainboard 20 is electrically connected.Described second at 132 and the third 133 on can be only on second side 132
The contact point 21 is provided with, the contact point 21 can also be only provided on the third side 133, it can also be such as Fig. 3 institutes
Show, second in 132 and third while 133 on be both provided with the contact point 21, and contact point 21 and third on the second side 132
Contact point 21 on side 133 can be corresponded to position, can also position do not correspond to.
In the present embodiment, described " or/and " refer to relationship description between the two, if A or/and B includes three kinds of situations,
The first is that only A exists, and second is that only B exists, the third is that A and B exist.
The contact point 21 can directly be connect with the ground plane on mainboard 20, can also pass through series capacitance, inductance, switch
One or more in is connect again with ground plane, so as to increase by second at 132 or/and third 133 arrive ground plane
Between effective length.
Above-mentioned electronic equipment 100 described second in 132 or/and third while 133 on distance to first side 131 be
At the position of 1/4 λ ± 40 millimeter setting one with the mainboard 20 electrical connection contact point 21, and second side 132 or/
And third while be located on 133 the contact point 21 and it is described first while 131 between part be not provided with and be electrically connected with mainboard 20 again
Contact point, therefore, the charge on the frame 13 can be transferred to by the contact point 21 on mainboard 20 so that charge is assembled
In near contact point 21, when the holding of user is held in the second of frame 13 in 132 and third 133 on close to the first side
During 131 one end, the charge concentrated near the contact point of hand and metal frame greatly reduces, so that antenna energy quilt
The amount that hand absorbs reduces, and so as to enhance antenna transmitting or receive the ability of signal, promotes the transmitting-receiving effect of antenna.
As shown in figure 3, second in 132 and third while 133 on be both provided with the contact point 21 when, described two contacts
Point 21 can use simultaneously, can also be used alone.Specifically, switch 23, the switch 23 are additionally provided on the mainboard 20
With at least three gears, the switch 23 is used to switch the use state of described two contact points 21.Assuming that three gears point
Not Wei the first gear, the second gear and third gear, when the switch 23 is in the first gear, on second side 132
Contact point 21 is in use state, and the contact point 21 on third side 133 is in unused state；In the switch 23 in the
During two gears, the contact point 21 on the third side 133 is in use state, and the contact point 21 on second side 132 is in
Unused state；It is described switch 23 be at third gear when, described second at 132 and third 133 on contact point
21 all in use state.
When the switch 23 is from the first gear switch to the second gear, contact point 21 on second side 132 is from making
Unused state is switched to state, and the contact point 21 on the third side 133 is switched to use state from unused state；
The switch 23 from the second gear be switched to third gear when, the contact point 21 on the third side 133 keeps in service, institute
The contact point stated on the second side 132 is switched to unused state from unused state；Switch in the switch 23 from third gear
During to the first gear, the contact point 21 on second side 132 keeps in service, and the contact point 21 on third side 133 from
Use state is switched to unused state.Certainly, the switch 23 can also be switched to the first gear from the second gear, from described
First gear switch is switched to the second gear to third gear from the third gear.
In a specific embodiment, the length of the first segment 111 is 50 millimeters~90 millimeters.That is, contact point
21 be set to second at 132 or/and third 133 on distance to first side 131 be 50 millimeters~90 millimeters of position
Place.
For existing wireless transceiver 30 center frequency point for 700MHz~960MHz, the contact point 21 is set to the
Two at 132 or/and third 133 on distance to first side 131 be (1/4 λ -15 millimeters)~(1/4 λ -25 millimeters)
At position.Such as：It is 900MHz in the center frequency point of wireless transceiver 30, the optimum position of the contact point 21 is located at the second side
132 or/and third 131 distance when arriving described first on 133 be at 70 millimeters of position.
Further, described second at 132 and the third insulation material is provided between 133 and first side 131
Material or gap 135, so that described first when the charge on 131 cannot be transferred to second 132, similarly, described first
On when 131 can not be transferred to the third 133.
In addition, described second is also equipped with insulating materials at 132 and the third between 133 and the 4th side 134
Or gap 136, so that the described 4th when the charge on 134 cannot be transferred to second 132, and similarly, the 4th side
134 can not be transferred on the third side 133.Alternatively, as shown in figure 4, described second at 132 and the third 133 with
Insulating materials or gap can not also be provided between 4th side 134, the charge on the 4th side 134 can shift
To second at 132 and third 133 on.
Further, other than setting the contact point 21, as shown in figure 4, one can also be set on second segment 112
A or multiple contact points 22 with the mainboard 20 electrical connection.Charge on the frame 13 can also pass through the contact
Point 22 is transferred on the mainboard 20.The number of the contact point 22 can be arranged as required to.
In addition, described second at 132 and/or the third the distance between 133 and the mainboard 20 it is bigger, can more drop
The low electromagnetic interference of signal that the wireless transceiver 30 is received or emitted promotes the transmitting-receiving effect of wireless transceiver 30.
But due to the limitation of 100 size of electronic equipment, described second at 132 and/or the third 133 with the mainboard 20 it
Between the shortest distance could be provided as 0~3 millimeter.Preferably, with reference to the size of existing electronic equipment, second side
The shortest distance between 132 and/or the third side 133 and the mainboard 20 is 2 millimeters.
It if, can be by second side it is to be appreciated that when being provided with the contact point 21 on only described second side 132
The distance between 132 and the mainboard 20 are set greater than the distance on the third side 133 and the mainboard 20, accordingly, if
It, can will be between the third side 133 and the mainboard 20 only when being provided with the contact point 21 on the third side 133
Distance is set greater than the distance on second side 132 and the mainboard 20, so as to further reduced to the wireless receiving and dispatching
The electromagnetic interference of signal that device 30 is received or emitted promotes the transmitting-receiving effect of wireless transceiver 30.
Above-mentioned electronic equipment 100 described second in 132 or/and third while 133 on distance to first side 131 be
At the position of 1/4 λ ± 40 millimeter setting one with the mainboard 20 electrical connection contact point 21, and second side 132 or/
And third while be located on 133 the contact point 21 and it is described first while 131 between part be not provided with and be electrically connected with mainboard 20 again
Contact point, therefore, the charge on the frame 13 can be transferred to by the contact point 21 on mainboard 20 so that charge concentration
Near contact point 21, when the holding of user is held in the second of frame 13 in 132 and third 133 on close to the first side 131
One end when, the charge concentrated near the contact point of hand and metal frame greatly reduces, so that antenna energy is by hand
The amount of absorption reduces, and so as to enhance antenna transmitting or receive the ability of signal, promotes the transmitting-receiving effect of antenna.
