     TECHNICAL FIELD OF THE INVENTION 
     The disclosure relates to a connector and an electronic system using the same and, more particularly, to a high frequency connector and an electronic system using the same. 
     BACKGROUND 
     Conventionally, coaxial cables are used as connectors in transmission of high frequency signals or connection of different electronic communication products. However, since the coaxial cable connector is larger and occupies much space, it is difficult to be applied to a small-sized portable electronic device (such as a phone). On the other hand, since the architecture of the coaxial cable connector is fixed and is not easy to be changed, it is difficult to be customized for various products. Moreover, the manufacturing cost of the coaxial cable connector is high. 
     In addition, a coplanar waveguide technology is another common conventional high frequency signal transmission technology. The coplanar waveguide technology has a feature that it includes a single plane of transmission lines, that means, a signal line and a grounding line are in the same plane, which makes electronic components connected to each other in series or parallel easily. Moreover, the coplanar waveguide technology makes electric characteristic of the electronic components not easily affected by the thickness of a dielectric plate. Consequently, the manufacturing cost of circuits is greatly reduced, and a circuit layout has more choices.

FIG. 2  is an enlarged view of partial of the connector connecting two electronic devices in  FIG. 1 . Please refer to  FIG. 1  and  FIG. 2 , in the embodiment, an electronic system  100  includes a first electronic device  102 , a second electronic device  200  and a connector  104 . In the embodiment, the first electronic device  102  includes a plurality of first connection points  103 , and the second electronic device  200  includes a plurality of second connection points  210 . The connector  104  includes a first grounding terminal  110 , a signal terminal  120  and a second grounding terminal  130 . The signal terminal  120  is between the first grounding terminal  110  and the second grounding terminal  130 . In an embodiment, the first grounding terminal  110 , the signal terminal  120  and the second grounding terminal  130  is made of conducting materials, such as a metal material. 
     In the embodiment, the first grounding terminal  110  includes a first end  112  and a second end  114 . The signal terminal  120  includes a third end  122  and a fourth end  124 , and the second grounding terminal  130  includes a fifth end  132  and a sixth end  134 . The first end  112 , the third end  122  and the fifth end  132  are electrically connected to the first electronic device  102 , respectively. The second end  114 , the fourth end  124  and the sixth end  134  are electrically connected to the second electronic device  200 , respectively. 
     In the embodiment, the first end  112 , the third end  122  and the fifth end  132  are electrically connected to one of the first connection points  103  by welding or other methods, respectively. When the first electronic device  102  is connected to the second electronic device  200 , the second end  114 , the fourth end  124  and the sixth end  134  are electrically connected to one of the second connection points  210 , respectively. 
     In an embodiment, the second electronic device  200  includes an accommodation slot  220  to accommodate the first electronic device  102 . In detail, after the first electronic device  102  is accommodated in the accommodation slot, the first electronic device  102  is integrated to the second electronic device  200  to have a smooth appearance. In the embodiment, the first electronic device  102  is an electronic communication product, such as a phone. 
       FIG. 3  is a side view of partial of the connector in  FIG. 1 . Please refer to  FIG. 2  and  FIG. 3 , the first connection points  103  are at a first plane P 10  of the first electronic device  102 , and the second connection points  210  are at a second plane P 20  of the second electronic device  200 . The first plane P 10  and the second plane P 20  are not coplanar. That means, in the embodiment, the connector  104  can be connected to connection points at different planes, and signals are transmitted among the connection points at different planes. Additionally, to conform to the coplanar waveguide theory, the first end  112 , the third end  122  and the fifth end  132  are at the same plane, and they are electrically connected to the first connection points  103  at the first plane P 10 , respectively.

Since the signal terminal  120  is between the first grounding terminal  110  and the second grounding terminal  130 , the first grounding terminal  110  and the second grounding terminal  130  can be the shields for the signal terminal  120 , it can avoid that the signals transmitted by the signal terminal  120  is interfered by external disturbance. In detail, since the first grounding terminal  110  and the second grounding terminal  130  are equipotential, a certain potential difference is maintained between the first grounding terminal  110  and the signal terminal  120 , and also between the second grounding terminal  130  and the signal terminal  120 . As a result, grounding lines surround a signal line, and then the signal transmission quality of the signal line is maintained, and the loss of signals is avoided. 
     In order to increase a contacting area to maintain stability of the electrical connection, in the embodiment, the first end  112 , the third end  122 , the fifth end  132 , the second end  114 , the fourth end  124  and the sixth end  134  are flat-shaped, which is not limited herein, the shape can be adjusted according to requirements and the space. 
     In the embodiment, the connector  104  further includes a casing  140 . The first grounding terminal  110 , the signal terminal  120  and the second grounding terminal  130  are partially disposed inside the casing  140 . The casing  140  can be used to prevent the first grounding terminal  110 , the signal terminal  120  and the second grounding terminal  130  from moisture erosion, and it can also avoids the deformation of the first grounding terminal  110 , the signal terminal  120  and the second grounding terminal  130 . 
     In conclusion, according to the connector and the electronic system in the embodiments, the signal terminal is between the first grounding terminal and the second grounding terminal, and the first grounding terminal and the second grounding terminal can shield external disturbance to avoid the interference on the high frequency signal transmitted by the signal terminal. In addition, the terminal of the connector can be adjusted in the three-dimensional stereoscopic space, and thus the connection points at different planes can be connected, which can easily meets the customized requirements.
