Abstract:
An electronic device includes an enclosure, a connector, a connector cover, and a resisting member. The enclosure defines at least one opening. The connector is disposed in the enclosure and corresponding to the at least one opening of the enclosure. The connector cover covers the opening to protect the connector and includes pivot shaft. The pivot shaft is rotatably connected to the enclosure. The resisting member elastically resists against the connector cover. The resisting member may be formed by a spring biased block that presses in an end of the pivot shaft to maintain the cover in open or closed position. A restricting member may be located in the opening to limit cover rotation in both open and closed positions.

BACKGROUND 
     1. Technical Field 
     The present disclosure relates to electronic devices, and in particular to an electronic device having protected external connectivity. 
     2. Description of Related Art 
     Hardware interfaces such as universal serial bus (USB) ports often provide electronic device connection to portable storage devices, external players, or other electronic devices, for transferring data therebetween. A connector cover is favorable to have for protecting the data interface when not in use. 
     A conventional connector cover is often a single detachable element. When the hardware interface is in use, the connector cover is temporarily detached from the hardware interface, and thus may be lost or misplaced, resulting in the connector being unprotected when not in use. 
     Therefore, there is room for improvement within the art.

     DETAILED DESCRIPTION 
     The disclosed electronic device may be a personal digital assistant (PDA), a MP3 player, a digital photo frame, a liquid crystal display monitor, or other electronic device. Referring to  FIG. 1  and  FIG. 2 , an embodiment of an electronic device  100  includes an enclosure  10 , a connector cover  50 , a resisting member  70 , and a resilient member  90 . The enclosure  10  includes a main body  20  and a cover  30  installed with the main body  20 . 
     Referring also to  FIGS. 3 through 6 , the cover  30  includes a first receiving portion  32 , a second receiving portion  34 , and a restricting member  36 . The first receiving portion  32  is depressed from an outer surface of an end of the cover  30 . The first receiving portion  32  includes a first sidewall  322 , a second sidewall  324 , a third sidewall  326 , and a fourth sidewall  328 . The first sidewall  322  and the second sidewall  324  are a plurality of substantially rectangular boards. The first sidewall  322  extends from a side of the second sidewall  324  away from the end of the cover  30  from which the first receiving portion  32  is depressed. The third sidewall  326  is positioned at an end of the first sidewall  322  and the second sidewall  324 . The fourth sidewall  328  is positioned at an end of the first sidewall  322  and the second sidewall  324 , that is opposite to the third sidewall  326 . The first sidewall  322  defines at least one opening  329 . The electronic device  100  further includes at least one connector  332  received in the enclosure  10 , and the connector  332  corresponding to the at least one opening  329 . The third sidewall  326  defines a shaft hole  3262 . The second sidewall  324  and the fourth sidewall  328  cooperatively define a notch  3282  extending from an end of the second sidewall  324  adjacent to the fourth sidewall  328 . The fourth sidewall  328  defines a pivot hole  3284  corresponding to the shaft hole  3262 , and the pivot hole  3284  communicates with the notch  3282 . 
     The second receiving portion  34  is positioned inside of the cover  30  and adjacent to the fourth sidewall  328 . The second receiving portion  34  is substantially U-shaped, and includes a first plate  342 , a second plate  344 , and a third plate  346 . The second plate  344  is substantially parallel to the fourth sidewall  328 . The first plate  342  and the third plate  346  interconnect the second plate  344  and the fourth sidewall  328 . The notch  3282  and the pivot hole  3284  communicate between the first receiving portion  32  and the second receiving portion  34 . 
     The restricting member  36  is substantially a block fixed to a surface of the third sidewall  326  facing the fourth sidewall  328 . The restricting member  36  is positioned between the shaft hole  3262  and the first sidewall  322 . The restricting member  36  includes a first restricting portion  362  and a second restricting portion  364 . The first restricting portion  362  extends to the second sidewall  324 . The second restricting portion  364  angles from an end of the first restricting portion  362  away from the second sidewall  324 . The second restricting portion  364  includes a restricting surface  3642  at a side of the second restricting portion  364  away from the second sidewall  324 . 
     The connector cover  50  includes a base plate  52 , a rotation shaft  54 , a pivot shaft  56 , and a receiving portion  58 . The base plate  52  is substantially rectangular and matches the first receiving portion  32 . The rotation shaft  54  and the pivot shaft  56  extend from a plurality of central portions of two opposite ends of the base plate  52 . The receiving portion  58  is formed at an end of the pivot shaft  56  away from the base plate  52 . In the illustrated embodiment, the receiving portion  58  is substantially cylindrical, and the diameter of the receiving portion  58  exceeds that of the pivot shaft  56 . The receiving portion  58  forms a plurality of protrusions (not labeled) on an outer surface thereof to increase the surface roughness of the receiving portion  58 . 
     The resisting member  70  is substantially a rectangular block, capable of being received in the second receiving portion  34 . The resisting member  70  defines a receiving groove  72  depressed from an end surface of the resisting member  70 . The resisting member  70  forms a contact surface  74  at an opposite end thereof. The contact surface  74  is arcuate. 
     The resilient member  90  is partly receivable in the receiving groove  72 . In the illustrated embodiment, the resilient member  90  is a spring. 
     In the assembly of the electronic device  100 , an end of the resilient member  90  is received in the receiving groove  72  and an opposite end of the resilient member  90  extends out from the end surface of the resisting member  70 . The resilient member  90  and the resisting member  70  are received in the second receiving portion  34  with the end of the resilient member  90  to be extending from the resisting member  70  and resisting the first plate  342 . The end of the resisting member  70  away from the resilient member  90  corresponds to the pivot hole  3284 . The rotation shaft  54  is received in the shaft hole  3262 . The pivot shaft  56  is received in the pivot hole  3284  through the notch  3282 . The receiving portion  58  is received in the second receiving portion  34 , and resists the contact surface  74 , and the resilient member  90  is compressed. 
     Referring also to  FIG. 7 , when the connector  332  is to be used, an external force applied on an end of the connector cover  50  adjacent to the second sidewall  324  rotates the connector cover  50  relative to the enclosure  10  until the base plate  52  abuts the end of the first restricting portion  362  adjacent to the second sidewall  324 , and the connector  332  is exposed. The resisting member  70  elastically resists the receiving portion  58  of the connector cover  50  to keep the connector cover  50  open. 
     When the connector  332  is not in use, an external force applied on an end of the connector cover  50  away from the first sidewall  322  rotates the connector cover  50  relative to the enclosure  10  until the base plate  52  is abutting the restricting surface  3642 , and the connector cover  50  covers the first receiving portion  32 . The resisting member  70  elastically resists the receiving portion  58  of the connector cover  50  to keep the connector cover  50  closed. 
     When the connector  332  is in use, the connector cover  50  is rotated rather than being removed from the electronic device  100 , thereby avoiding loss or misplacement thereof, and retaining protection of the connector  332 . 
     The resilient member  90  resists the receiving portion  58  of the connector cover  50 , such that the resistance while the connector cover  50  rotates is increased, and the connector cover  50  remains closed or opened relative to the first receiving portion  32 . 
     The rotation shaft  54  and the pivot shaft  56  are located in the central portions of the two opposite ends of the base plate  52 , such that when the connector  332  is in use, the connector  332  is at least partially received in the first receiving portion  32 , and the electronic device  100  thus occupies less space, and the connector cover  50  is well protected. 
     The restricting member  36  may be omitted, whereby the rotation of the connector cover  50  is stopped as long as the connector  332  is exposed. The cover  30  may be omitted, as long as the enclosure  10  is molded as a whole. The receiving portion  58  of the connector cover  50  may be omitted, whereby the pivot shaft  56  resists the resisting member  70 . The resilient member  90  may be omitted, whereby the resisting member  70  is made of elastic materials. The first receiving portion  32  may be omitted, whereby the connector cover  50  is rotatably connected to the enclosure  10 , such as the enclosure  10  forms two protrusions positioned at two opposite ends of the opening  329 , and each protrusion defines a shaft hole in which one of the rotation shaft  54  and the pivot shaft  56  is received. 
     It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the disclosure or sacrificing all of its material advantages.
