Abstract:
A two-side cable-arrangement structure is disclosed. The two-side cable-arrangement structure includes a plate, a first cable-arrangement structure, and a second cable-arrangement structure. The first cable-arrangement structure and the second cable-arrangement structure are respectively disposed on two sides of the plate. A cable is fixed on the two sides of the plate by the first cable-arrangement structure and the second cable-arrangement structure simultaneously. Thereby, the cable is constrained at both the direction vertical toward the plate and the direction vertical away from the plate, and the fixed cable is not easy to move by pulling. It solves the difficulty of fixing a cable completely by a conventional single-side cable-arrangement structure in the prior art.

Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The invention relates to a two-side cable-arrangement and an electronic apparatus therewith, and especially relates to a two-side cable-arrangement and an electronic apparatus therewith using reciprocal effect by two cable arrangement structures disposed oppositely to enhance immobility of a cable. 
         [0003]    2. Description of the Prior Art 
         [0004]    As electronic technology progresses, various electronic apparatuses are developed continuously. Most of electronic components in the electronic apparatus are integrated into a print circuit board, but some electronic modules are still electrically connected with cables. These connection cables or cables with other functions (such as antenna, power cable and so on) are often accommodated by hanging in the casing of the electronic apparatus. In order to avoid improperly tangling the cables and shorting the cables with other electronic components, or in order to effectively dispose the cables for improving efficiency of later maintenance, the electronic apparatus often includes cable-arrangement structures disposed in the interior to solve the above problems. 
         [0005]    Please refer to  FIG. 1 , which is a schematic diagram of a single-side cable-arrangement structure  1  according to the prior art. In this embodiment, the single-side cable-arrangement structure  1  is disposed at a corner of a casing  12  for fixing a cable  2 . The single-side cable-arrangement structure  1  consists mainly of ribs  14 ,  16  disposed in parallel. The ribs  14 ,  16  form a passage  18  therebetween. The cable  2  can be accommodated in the passage  18 . In addition, there are several protrusion spots  142 ,  162  disposed on the side walls of the passage  18  for fixing the cable  2  in the passage  18  firmly. The cable  2  passes through a through hole  122  to the exterior of the casing  12 . In this embodiment, the cable  2  is constrained in plane directions, but when a user outside the casing  12  pushes the cable  2  in, it is quite easy for the cable  2  to depart along a direction  124  perpendicular to the casing  12  from the passage  18 , so that the whole cable  2  departs from the single-side cable-arrangement structure  1 . 
         [0006]    Please refer to  FIG. 2 , which is a schematic diagram of the single-side cable-arrangement structure  1  on which an adhesive tape  20  is pasted. The adhesive tape  20  is shown in dashed lines. In view of the problem of departing, a conventional method is to paste an adhesive tape over the whole single-side cable-arrangement structure  1  and the cable  2  additionally to prevent the cable  2  from departing, shown as  FIG. 2 . However, as time goes by, the stickiness of the adhesive tape  20  decays till the adhesive tape  20  peels off. At this time, the abovementioned problem of departing also appears. 
         [0007]    Please refer to  FIG. 3 , which is a schematic diagram of another single-side cable-arrangement structure  3  according to the prior art. In this embodiment, the single-side cable-arrangement structure  3  is used for fixing an electronic component  4  (such as infrared lens) and wires  42  connected thereto. The single-side cable-arrangement structure  3  uses ribs  32  thereof to clip the wires  42  for the purpose of fixing the electronic component  4  and the wires  42  connected thereto. However, the way of fixing objects through the reciprocal resilient force induced by the deformation of the ribs  32  under the compression by the wires  42  needs a coordinating structure size, so the way is usually applied to a special assembly of components (such as the assembly of the electronic component  4  and the wires), not widely to the fixing on a single cable. 
       SUMMARY OF THE INVENTION 
       [0008]    An objective of the invention is to provide a two-side cable-arrangement structure for fixing a cable. The two-side cable-arrangement structure uses two cable-arrangement structures on two sides thereof to individually constrain the cable to produce the reciprocal effect so that the cable can be fixed firmly in each direction so as to solve the problem of the cable departing in the prior art. 
         [0009]    The two-side cable-arrangement structure of the invention includes a plate, a first cable-arrangement structure, and a second cable-arrangement structure. The plate has a first side and a second side. The first side is opposite to the second side. The first cable-arrangement structure is disposed on the first side for fixing a first portion of the cable on the first side. The second cable-arrangement structure is disposed on the second side for fixing a second portion extending from the first portion of the cable on the second side. 
         [0010]    Because the cable is fixed on the two opposite sides of the plate simultaneously, using the free portion of the cable at the second side to loosen the cable at the first side needs to overcome the constraint on the second portion of the cable by the second cable-arrangement structure, and vice versa. Furthermore, the cable is fixed by the two cable-arrangement structures simultaneously, so a constraint force is produced between the first portion and the second portion of the cable. The constraint force is not based on the cable-arrangement structure itself, but based on the existence of the other cable-arrangement structure, so the relative disposal of the two cable-arrangement structures affects the constraint force. In the two-side cable-arrangement structure of the invention, the first cable-arrangement structure and the second cable-arrangement structure are disposed on the two sides of the plate respectively, so the constraint force thereof is larger than the constraint force produced by two cable-arrangement structures disposed at the same side. 
         [0011]    Another objective of the invention is to provide an electronic apparatus with the two-side cable-arrangement structures of the invention. The electronic apparatus includes a casing additionally. The casing is engaged with the plate. The casing has a through hole for the cable to pass through to the exterior of the casing. Besides the electronic apparatus having the effect of the above two-side cable-arrangement structure, the cable is constrained further by the through hole. For example, the through hole is not opposite right to the cable-exit position of the two-side cable-arrangement structure, so it is harder for a user from the exterior of the electronic apparatus to directly loosen the portions of the cable fixed by the two-side cable-arrangement structure. 
         [0012]    Therefore, the two-side cable-arrangement structure and the electronic apparatus with the two-side cable-arrangement structure of the invention can fix the cable firmly. The fixed portions of the cable are difficult to be loosened even though a user pulls out or pushes in the cable outside the electronic apparatus. The cable is therefore fixed effectively, which solves the problem that the single cable-arrangement structure in the prior art cannot fix a cable in multiple directions. 
         [0013]    These and other objectives of the present invention will no doubt become obvious to those of ordinary skill in the art after reading the following detailed description of the preferred embodiment that is illustrated in the various figures and drawings.

     DETAILED DESCRIPTION 
       [0021]    Please refer to  FIG. 4  and  FIG. 5 .  FIG. 4  is a schematic diagram of a two-side cable-arrangement structure  5  according to a preferred embodiment of the invention.  FIG. 5  is a schematic diagram of the two-side cable-arrangement structure  5  in  FIG. 4  in another view. The two-side cable-arrangement structure  5  is used for fixing a cable (shown in dashed lines in the figures). The two-side cable-arrangement structure  5  includes a plate  52 , a first cable-arrangement structure  54 , and a second cable-arrangement structure  56 . The plate  52  includes a first side  522  and a second side  524 . The first side  522  is opposite to the second side  524 . The first cable-arrangement structure  54  is disposed on the first side  522  for fixing a first portion  62  of the cable  6  on the first side  522 . The second cable-arrangement structure  56  is disposed on the second side  524  for fixing a second portion  64  extending from the first portion  62  of the cable  6  on the second side  524 . 
         [0022]    Further, the first cable-arrangement structure  54  substantially forms a cable passage which includes a cable inlet  542 , a holding part  544 , and a cable outlet  546 . The second cable-arrangement structure  56  also substantially forms a cable passage which includes a cable inlet  562 , a holding part  564 , and a cable outlet  566 . The first portion  62  of the cable  6  passes through the cable inlet  542 , the cable outlet  546  of the first cable-arrangement structure  54  and is fixed by the holding part  544  of the first cable-arrangement structure  54 . In this embodiment, the cable outlet  546  of the first cable-arrangement structure  54  communicates with the cable inlet  562  of the second cable-arrangement structure  56 , so the cable  6  directly crosses the plate  52  to from the first cable-arrangement structure  54  enter the second cable-arrangement structure  56 ; however, the invention is not limited to this. The second portion  64  of the cable  6  passes through the cable inlet  562  and the cable outlet  566  of the second cable-arrangement structure  56  and is fixed by the holding part  564  of the second cable-arrangement structure  56 . 
         [0023]    In this embodiment, the holding part  564  of the second cable-arrangement structure  56  is used for fixing the second portion  64  of the cable  6  so that the fixed portion of the second portion  64  of the cable  6  extends along a first fixing direction  66 . In the operation of fixing the cable  6 , because the holding part  564  has an open  5642 , a user can dispose the second portion  64  of the cable  6  along a direction perpendicular to the first fixing direction  66  from the open  5642  into the holding part  564 , so that the second portion  64  of the cable  6  is fixed. In addition, there is a distance  58  along the direction perpendicular to the first fixing direction  66  between the cable inlet  562  and the holding part  564 . Therefore, after passing through the cable inlet  562  of the second cable-arrangement structure  56 , the second portion  64  of the cable  6  extends along a first direction  68  and is bent to extend along a second direction (i.e. the first fixing direction  66 ), so as to be fixed by the holding part  564 . Furthermore, because the cable inlet  562  is shifted relatively to the open  5642 , the cable inlet  562  is also conducive to preventing the cable  6  from departing from the open  5642 . 
         [0024]    In addition, because of the bending of the cable  6  due to the traverse of the cable  6  across the plate  52 , the cable  6  is bent several times to be fixed. Thereby, the cable  6  suffers multiple constraints, which increases the constraint force on the cable  6  produced by the first cable-arrangement structure  54  and a second cable-arrangement structure  56  when respectively fixing the cable  6  and is further conducive to fixing the cable  6 . 
         [0025]    In this embodiment, the first portion  62  of the cable  6  is simply disposed in a narrow groove and fixed by the holding part  544  so that the first portion  62  of the cable  6  extends along a second fixing direction  70 . The second fixing direction  70  is reverse to the first fixing direction  66 . In other words, the cable  6  extends mainly along a third direction (i.e. the second fixing direction  70 ) before entering the second cable-arrangement structure  56 , and extends mainly along the second direction (i.e. the first fixing direction  66 ) reverse to the third direction after entering the second cable-arrangement structure  56 . Therefore, the extending path of the cable  6  is conducive to reducing the movement along the path and to fixing the cable  6 . In this embodiment, the first cable-arrangement structure  54  and the second cable-arrangement structure  56  are not wholly symmetric, but the invention is also applied to a case of a symmetric structure without further descriptions. 
         [0026]    It is added that, in this embodiment, the first cable-arrangement structure  54  uses the similar fixing means to that used by the second cable-arrangement structure  56 ; that is, the holding part  544  compresses the cable  6  for preventing the cable  6  from departing from the cable passage formed by the first cable-arrangement structure  54 . However, the invention is not limited to this. Please refer to  FIG. 6 , which is a schematic diagram of the first cable-arrangement structure  54  according to another embodiment of the invention. A cable passage formed by the first cable-arrangement structure  54  is a groove  548 , of which there is at least one protrusion spots  550  disposed on the two sides. The first portion  62  of the cable  6  passes through the cable inlet  542  and the cable outlet  546  and is fixed in the groove  548  by the protrusion spots  550  protruding toward the groove  548 . The holding part  544  in  FIG. 4  and the protrusion spots  550  in  FIG. 6  can also be used together without specially pointing out. 
         [0027]    Please refer to  FIG. 5 . In the above embodiments, the cable  6  leaves the two-side cable-arrangement structure  5  from the cable outlet  566 . The cable  6  usually extends out of an electronic apparatus accommodating the two-side cable-arrangement structure  5 , so a user may pull or push the exposed cable  6 . When the user pulls the exposed cable  6 , the holding part  564  can resist pulling the cable  6  from the second cable-arrangement structure  56 . When the user pushes the exposed cable  6 , the cable  6  is blocked by the wall at the cable outlet  566  of the second cable-arrangement structure  56  so that the second portion  64  of the cable  6  will not be loosened or depart from the holding part  564 . Therefore, the two-side cable-arrangement structure  5  of the invention can fix the cable  6  efficiently and greatly reduce the possibility of the cable loosing due to pulling or pushing the cable  6  by the user. 
         [0028]    Please refer to  FIG. 7 , which is a schematic diagram of an electronic apparatus  7  according to another preferred embodiment of the invention. The electronic apparatus  7  includes a casing  72  (shown in dashed lines) and the abovementioned two-side cable-arrangement structure  5 . The casing  72  is engaged with the plate  52  and has a through hole  722 ; the detail of the engagement is not shown in  FIG. 7 . The casing  72  of the electronic apparatus  7  usually forms an accommodating space for accommodating the plate  52  and other electronic components. The cable  6  is usually connected to an electronic component, is fixed by the two-side cable-arrangement structure  5 , and passes through the through hole  722  to the exterior of the electronic apparatus  7 . The cable  6  could be an FM antenna, a power cable or other cables. 
         [0029]    Because it is necessary for the user to pull or push the exposed portion of the cable  6  through the through hole  722 , the position of the through hole  722  affects the pulling or pushing. In this embodiment, there is a distance  74  along a direction perpendicular to the second direction (i.e. the first fixing direction  66 ) between the projection of the through hole  722  on the plate  52  and the holding part  564  of the second cable-arrangement structure  56 ; that is, the projection is shifted by the distance  74  along the direction along which the cable  6  enters into the holding part  564  to be held. Thereby, when the user pulls the cable  6 , it is more difficult to pull the cable  6  to be loosened because the cable  6  is constrained by the through hole  722  and then held by the holding part  564 . When the user pushes the cable  6 , the fixed portion of the second portion  64  of the cable  6  cannot be directly loosened by the pushing because there is the distance  74  between the projection of the through hole  722  and the cable outlet  566 . In a general case, the pushed cable  6  is stopped by the plate  52 , so the second cable-arrangement structure  56  affect less the fixing effect on the cable  6 . 
         [0030]    Therefore, the cable-arrangement structures are disposed on the two sides of the plate of the two-side arrangement structure of the invention, so that the cable is double fixed by the cable-arrangement structures on the two sides, which provides the fixing effect in multiple directions on the cable. The portions of the cable fixed by the two cable-arrangement structures pull each other to produce a constraint force on both of the portions. The constraint force is conducive to preventing the cable from moving so as to enhance the fixing on the cable. In addition, besides having the abovementioned fixing effect on the cable, the electronic apparatus with the two-side cable-arrangement structure of the invention can greatly reduce the effect of loosening the cable by the user pulling or pushing the exposed portion of the cable. Therefore, the two-side cable-arrangement structure and the electronic apparatus with the two-side cable-arrangement structure of the invention solve the problem in the prior art that a user pulls or pushes a exposed portion of a cable fixed on a single cable-arrangement structure to loosen the cable, even damage the cable. 
         [0031]    Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention.
