BACKGROUND 
     1. Technical Field 
     The present disclosure relates to an adaptor and a storage device using such adaptor. 
     2. Description of Related Art 
     Lightning is a proprietary computer bus and power connector created by Apple Inc. to replace its previous proprietary 30-pin dock connector, and is used to connect Apple mobile devices like iPhones, iPads and iPods to host computers, external monitors, cameras, USB battery chargers and other peripherals. Using eight pins instead of thirty, Lightning is significantly more compact than the 30-pin dock connector and can be inserted with either side facing up. At least C10A Lightning connectors and C68A Lightning connectors have existed in the market. In general, a C68A Lightning connector is cheaper 29% in price and smaller 58% in volume than a C10A Lightning connector, so C68A Lightning connectors have become the mainstream.

     Therefore, it can be seen that the first pin  141  is configured for transmitting accessory power. The second pin  142  is configured for transmitting device power. The third pin  143  and the fourth pin  144  are configured for transmitting differential pair signals (D+, D−). The fifth pin  145  and the sixth pin  146  are configured for grounding. As a result, the storage device  100  combining the Apple Lightning connector  130  with the adaptor  140  is provided with functions of charging, power supplying, and communicating. 
     In some embodiments, because the first pin  141  and the second pin  142  are configured for transmitting power and the fifth pin  145  and the sixth pin  146  are configured for grounding, for considering an optimal design of the adaptor  140 , widths of the third pin  143  and fourth pin  144  can be smaller than widths of the first pin  141 , the second pin  142 , the fifth pin  145 , and the sixth pin  146 . In other words, the widths of the pins for transmitting power (i.e., the first pin  141  and the second pin  142 ) and/or grounding (i.e., the fifth pin  145  and the sixth pin  146 ) can be greater than the widths of the pins for transmitting signals (i.e., the third pin  143  and the fourth pin  144 ). 
     Reference is made to  FIG. 4 .  FIG. 4  is a cross-sectional view of the components taken along line  4 - 4  in  FIG. 2A  according to some embodiments of the disclosure. 
     As shown in  FIG. 3A  to  FIG. 4 , the first contacting portion  141   a , the second contacting portion  142   a , the third contacting portion  143   a , the fourth contacting portion  144   a , the fifth contacting portion  145   a , and the sixth contacting portion  146   a  substantially extend along a direction. The first circuit board  120  has an upper surface  120   a  and a lower surface  120   b  opposite to each other. The first extending portion  141   b , the second extending portion  142   b , the third extending portion  143   b , the fourth extending portion  144   b , the fifth extending portion  145   b , and the sixth extending portion  146   b  are coplanar and extend on the upper surface  120   a  of the first circuit board  120 . In general, widths of the first upper contact  130   a   1 , the second upper contact  130   a   2 , the third upper contact  130   a   3 , the fourth upper contact  130   a   4 , the fifth upper contact  130   a   5 , the first lower contact  130   b   1 , the second lower contact  130   b   2 , the third lower contact  130   b   3 , and the fourth lower contact  130   b   4  of the Apple Lightning connector  130  are in a range from about 0.6 mm to about 1.23 mm. In order to meet the above width limitation under the structural configuration, the width of any of the first pin  141 , the second pin  142 , the fifth pin  145 , and the sixth pin  146  is in a range from about 0.36 mm to about 0.5 mm, and no structural interference will occur between the first pin  141  and the second pin  142  or between the fifth pin  145  and the sixth pin  146 . 
     In some embodiments, the fixing block  147  is an insulating block, so as to isolate the first pin  141 , the second pin  142 , the third pin  143 , the fourth pin  144 , the fifth pin  145 , and the sixth pin  146  from each other. 
     In some embodiments, the storage device  100  is a flash drive, but the disclosure is not limited in this regard. 
     Reference is made to  FIG. 5 .  FIG. 5  is a bottom view of some components in  FIG. 2B  according to some other embodiments of the disclosure. 
     As shown in  FIG. 5 , the first contacting portion  141   a  and the second contacting portion  142   a  extend along different directions. The fifth contacting portion  145   a  and the sixth contacting portion  146   a  extend along different directions. Specifically, the first contacting portion  141   a  extends away from the second upper contact  130   a   2 , and the sixth contacting portion  146   a  extends away from the fourth upper contact  130   a   4 , so it is more unlikely to cause a structural interference between the first pin  141  and the second pin  142  or between the fifth pin  145  and the sixth pin  146 , and the widths of the first pin  141 , the second pin  142 , the fifth pin  145 , and the sixth pin  146  can be increased as possible, which is beneficial to transmitting power and grounding. 
     Other details regarding the components of  FIG. 5  are similar to the components of  FIG. 3A  and therefore are not repeated here to avoid duplicity. 
     Reference is made to  FIG. 6 .  FIG. 6  is a cross-sectional view of the components taken along line  4 - 4  in  FIG. 2A  according to some other embodiments of the disclosure. 
     As shown in  FIG. 6 , the second extending portion  142   b , the third extending portion  143   b , the fourth extending portion  144   b , and the fifth extending portion  145   b  extend on the lower surface  120   b  of the first circuit board  120 , and the first extending portion  141   b  and the sixth extending portion  146   b  extend on the upper surface  120   a  of the first circuit board  120 , so it is more unlikely to cause a structural interference between the first pin  141  and the second pin  142  or between the fifth pin  145  and the sixth pin  146 , and the widths of the first pin  141 , the second pin  142 , the fifth pin  145 , and the sixth pin  146  can be increased as possible, which is beneficial to transmitting power and grounding. 
     As shown in  FIGS. 2A and 2B , the storage device  100  further includes a holder  150 . The holder  150  envelops at least a part of the second circuit board  131 . The second circuit board  131  is fixed to the holder  150 , and the holder  150  is fixed to the first circuit board  120 . In some embodiments, the Apple Lightning connector  130  having the second circuit board  131  enveloped by the holder  150  is a C68A Apple Lightning connector  130 . 
     In some embodiments, the holder  150  is fixed to the first circuit board  120  by using SMT (Surface Mount Technology) or by manual welding, but the disclosure is not limited in this regard. 
     In some embodiments, the holder  150  is made of stainless steel, but the disclosure is not limited in this regard. 
     According to the foregoing recitations of the embodiments of the disclosure, it can be seen that in the adaptor used in the storage device, the widths of the pins for transmitting power or grounding are greater than the widths of the pins for transmitting signals, so as to provide an optimal design of the adaptor. By appropriately combining the Apple Lightning connector with the adaptor, the storage device is provided with functions of charging, power supplying, and communicating. In addition, the holder enveloping the Apple Lightning connector and fixed to the first circuit board can enhance the whole structural strength of the storage device. 
     Although the present disclosure has been described in considerable detail with reference to certain embodiments thereof, other embodiments are possible. Therefore, the spirit and scope of the appended claims should not be limited to the description of the embodiments contained herein. 
     It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present disclosure without departing from the scope or spirit of the disclosure. In view of the foregoing, it is intended that the present disclosure cover modifications and variations of this disclosure provided they fall within the scope of the following claims.
