     DETAILED DESCRIPTION 
     The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one. 
     Referring to  FIGS. 1 and 2 , one embodiment of an electronic device comprises a case  10  and a cable holding device  80 . In one embodiment, the cable holding device  80  may provide support for all input and output connections of the electronic device. 
     The case  10  comprises a bottom plate  11  and a front plate  17  connected to the bottom plate  11 . In one embodiment, the front plate  17  is substantially perpendicular to the bottom plate  11 . 
     A motherboard  112  is attached to the bottom plate  11 . A circuit board  20  is electronically connected to the motherboard  112  and adjacent to the front plate  17 . 
     Referring to  FIG. 2 , the circuit board  20  defines a plurality of securing holes  21  and two clipping holes  23  arranged on opposite sides of the plurality of securing holes  21 . In one embodiment, center points of the plurality of securing holes  21  and the two clipping holes  23  cooperatively defines an imaginary straight line. 
     The cable holding device  80  comprises a base  81  and a cable holding portion  83  connected to the base  81 . The base  81  defines a plurality of through holes  811  (shown in  FIG. 5 ) corresponding to the plurality of securing holes  21 . Two clipping portions, such as two hooks  813 , extend from a bottom surface of the base  81 . The two hooks  813  can be deformable to engage in the two clipping holes  23 . Each hook  813  comprises an extending portion  8131  and two engaging portions  8133 . The extending portion  8131  extends perpendicularly downwards from the bottom surface of the base  81 , and each engaging portion  8133  extends upwards in a slanting manner from the extending portion  8131 . In one embodiment, the cable holding device  80  is made of plastic. 
     The cable holding portion  83  comprises a side panel  831  and a top panel  833  connected to the side panel  831 . In one embodiment, the side panel  831  is substantially perpendicular to the top panel  833 . A plurality of positioning portion  835  is defined in the cable holding portion  83 . Each of the plurality of positioning portions  835  comprises a first positioning slot  8312  and a second positioning slot  8332  communicating with the first positioning slot  8312 . The first positioning slot  8312  is defined in the side panel  831 , and an extending direction of the first positioning slot  8312  is substantially parallel to base  81 . The second positioning slot  8332  communicates with each of the plurality of through holes  811 , and an extending direction of the second positioning slot  8332  is substantially perpendicular to the base  81 . In one embodiment, the first positioning slot  8312  communicates with each of the plurality of through holes  811  via the second positioning slot  8332 . A diameter of the first positioning slot  8312  is substantially equal to that of the second positioning slot  8332 , but greater than that of each of the plurality of through holes  811 . In one embodiment, a protrusion  836  is located between each first positioning slot  8312  and each second positioning slot  8332 . The protrusion  836  acts as a separator and a physical impediment between each first positioning slot  8312  and each second positioning slot  8332 . 
     Referring to  FIG. 3 , the cable holding device  80  is placed on the circuit board  20 , and the two hooks  813  are aligned with the two clipping holes  23 . The cable holding device  80  is pressed towards the circuit board  20 , and the two hooks  813  are deformed to engage in the two clipping holes  23 . At this time, the engaging portion  8133  is resisted on a bottom surface of the circuit board  20 . Thus, the cable holding device  80  is secured to the circuit board  20 . At this position, the plurality of securing holes  21  are aligned with the plurality of through holes  811 . 
     Referring to  FIGS. 4-5 , the cable holding device  80  can manage a plurality of cables  90  to electronically connect to the circuit board  20 . Each of the plurality of cables  90  comprises a cable core  91 . Each of the plurality of cables  90  is flexible after the point of connection to the cable holding device  80  may be located in a first position or a second position. In the first position, each of the plurality of cables  90  extends out of the first positioning slots  8312 , and bents for extending through the second positioning slots  8332 ; and the cable core  91  is engaged in a corresponding one of the plurality of through holes  811  and a corresponding one of the plurality of securing holes  21 . In the second position, each of the plurality of cables  90  extends out of the second positioning slots  8332 ; and the cable core  91  is engaged in a corresponding one of the plurality of through holes  811  and the corresponding one of the plurality of securing holes  21 . In one embodiment, the cable core  91  is electronically connected to the circuit board  20  by jointing. 
     In one embodiment, each first positioning slot  8312  is separated from each second positioning slot  8332 . However, the first positioning slot  8312  communicates with one of the plurality of through holes  811 , and the second positioning slot  8332  communicates with one of the plurality of through holes  811 . When each of the plurality of cables  90  is located in the first position, the plurality of cables  90  can directly extend from the first positioning slot  8312  to one of the plurality of through holes  811  and one of the plurality of the securing holes  21 . Therefore, when one of the plurality of cables  90  needs to be located in the first position, the plurality of cables  90  can be engaged in the first positioning slot  8312  and one of the plurality of through holes  811 . When one of the plurality of cables  90  needs to be located in the second position, the plurality of cables  90  can be engaged in the second positioning slot  8332 . 
     Although numerous characteristics and advantages have been set forth in the foregoing description of embodiments, together with details of the structures and functions of the embodiments, the disclosure is illustrative only and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
