2. Description of Related Art
A server is a core computer in a network system used for serving various computers, which can provide functions such as storage and print service for network users, and provide clients to share various resources within the network environment. A basic structure of the server is approximately the same to a general personal computer, which is composed of a central processing unit (CPU), a memory and an input/output (I/O) device, etc., and the devices are connected through a bus. A north bridge chip is used to connect the CPU and the memory, and the I/O device is connected through a south bridge chip. A chassis structure of the server has three evolution stages from earlier tower chassis to rack mount chassis stressing centrality, and then blade servers of high-density calculation.
Taking a rack mount server as an example, the rack mount server is a server with an appearance designed according to uniform standards, which is used in collaboration with a cabinet. The rack mount server can be regarded as a tower server with an optimized structure, and a design principle thereof is to reduce a space occupation of the server as far as possible. Many professional network devices apply the rack mount structure, and have a flat shape as that of a drawer, for example, switches, routers and hardware firewalls, etc. A width of the rack mount server is 19 inches, and a height thereof applies a unit of U (1U=1.75 inches=44.45 mm), and the servers are generally complied with standards of 1U, 2U, 3U, 4U, 5U or 7U.
The size of the cabinet also is also complied with a common industrial standard, which is generally between 22U and 42U. The cabinet includes a detachable sliding rack according to the height thereof, and the user can flexibly adjust the height according to a height of the server, so as to store network devices such as a server, a hub, a disk array, etc. After the server is settled, the I/O lines thereof are all led out from the rear of the cabinet (all interfaces of the rack mount server are also located at the rear of the cabinet), and are uniformly disposed in a cable slot of the cabinet, and are attached with labels to facilitate management.
Regarding a server having a pluggable hard disk module, when the hard disk module is moved relative to a chassis, cables connected to the hard disk module are also moved or curved. If the cables are not suitably fixed and are irregularly moved and curved, the cables can fall off from the hard disk module. Therefore, it is an important issue to maintain bending degrees of freedom of the cables while preventing the cables from falling off.
SUMMARY OF THE INVENTION
The invention is directed to a cable arranging module, which can prevent a cable set from falling off.

A first end of the chain structure is connected to the fixed frame, and a second end of the chain structure is connected to the electronic module. The fixed frame and the chain structure commonly form a chamber. The cable set is located in the chamber. When the electronic module is located in the chassis, the chain structure is bended and contained in the chassis. When the electronic module is pulled out from the chassis, the chain structure drives the cable set to be curved and move. When the electronic module is pulled out from the chassis entirely, the chain structure is extended and at least partially located out of the chassis.
In an embodiment of the invention, the electronic device is a server, and the electronic module is a hard disk module.

DETAILED DESCRIPTION OF DISCLOSED EMBODIMENTS
FIG. 1 is a three-dimensional view of an electronic device according to an embodiment of the invention. FIG. 2 is a three-dimensional view of a part of components of the electronic device of FIG. 1. For clarity's sake, a cable module 140 of FIG. 2 is shown in dot lines. Referring to FIG. 1 and FIG. 2, the electronic device 100 of the present embodiment includes a chassis 110, an electronic module 120, a switch board 130 and a cable arranging module 150. The electronic module 120 is disposed in the chassis 110, and is suitable for being pulled out from the chassis 110. The switch board 130 is disposed in the chassis 110. The cable arranging module 150 includes the cable set 140, a fixed frame 152 and a chain structure 154. The fixed frame 152 is fixed in the chassis 110. Two ends of the chain structure 154 are respectively connected to the fixed structure 152 and the electronic module 120. The fixed frame 152 and the chain structure 154 commonly form a chamber. The cable set 140 is located in the chamber and has a first segment 142 and a second segment 144. The first segment 142 is fixed to the fixed structure 152, and the second segment 144 is fixed to the chain structure 154. The first segment 142 is connected to the switch board 130 through an opening of the fixed frame 152, and the second segment 144 is connected to the electronic module 120 through an opening of the chain structure 154. In the present embodiment, the electronic device 100 is, for example, a server, and the electronic module 120 is, for example, a pluggable hard disk module. When the electronic module 120 is located in the chassis 110 as that shown in FIG. 2, the chain structure 154 is bended and contained in the chassis 110.
FIG. 3 is a three-dimensional view of the electronic device of FIG. 1 in case that the electronic module is pulled out from the chassis. FIG. 4 is a partial side view of the cable arranging module of FIG. 1. FIG. 5 is a partial side view of the cable arranging module of FIG. 3. When the electronic module 120 is pulled out from the chassis 110 (shown in FIG. 3 and FIG. 5), or the electronic module 120 is pushed in the chassis 110 (shown in FIG. 1 and FIG. 4), one end of the chain structure 154 connected to the electronic module 120 is driven to be moved relative to the chassis 110. During such process, the second segment 144 (shown in FIG. 2) is curved along with the chain structure 154, so that a whole structure thereof may have enough degrees of freedom. Since one end of the chain structure 154 is connected to the electronic module 120, a relative position between a tail end of the cable set 140 (shown in FIG. 2) and the electronic module 120 can be maintained, so as to prevent the cable set 140 from falling off from the electronic module 120 due to movement of the electronic module 120. When the electronic module 120 is entirely pulled out from the chassis 110 as that shown in FIG. 3 and FIG. 5, the chain structure 154 is extended and at least partially located out of the chassis 110.
In detail, the chassis 110 has a slide rail 170. The electronic module 120 is slidingly disposed on the slide rail 170. The fixed frame 152 is extended along a first axial line A1 (shown in FIG. 4 and FIG. 5), and the first axial line A1 is parallel to an extending direction of the slide rail 170 and located under the slide rail 170. When the electronic module 120 is located in the chassis 110, a part of the chain structure 170 is carried by the slide rail 170, and is located on a second axial line A2 (shown in FIG. 4) parallel to the first axial line A1. When the electronic module 120 is slid out from the chassis 110 along the slide rail 170, the chain structure 154 carried by the slide rail 170 departs from the slide rail 170 along the second axial line A2, and is partially moved to the first axial line A1 (shown in FIG. 5), and a part of the cable set 140 is curved along with the chain structure 154.
Referring to FIG. 2, in detail, the cable set 140 of the present embodiment is formed by a plurality of cables, and the cables include a plurality of data transmission lines 140a and a power line 140b. The electronic module 120 has a backplane 122. The backplane 122 has a plurality of connectors 122a, and the connectors 122a are connected to the cable set 140 to facilitate data and power transmission. The data transmission lines 140a and the power line 140b are fixed to the chain structure 154 and are extended out from a tail end of the chain structure 154 to connect the backplane 122. The tail end of the chain structure 154 is fixed to the electronic module 120, so that a relative position between the electronic module 120 and a segment of the data transmission lines 140a and the power line 140b at the tail end can be maintained, so as to reduce a chance that the data transmission lines 140a and the power line 140b fall off from the electronic module 120 can be reduced.
FIG. 6 is a top view of the electronic device of FIG. 1. For clarity's sake, a top surface of the chassis 110 is not illustrated in FIG. 6. Referring to FIG. 6, the electronic device 100 of the present embodiment further includes a motherboard module 160. The motherboard module 160 is disposed in the chassis 110, and the cable arranging module 150 is located between the motherboard module 160 and the electronic module 120. Based on such a high-density configuration method, the electronic device 100 may have a relatively small size to save a configuration space.
FIG. 7 is a three-dimensional view of the fixed frame and the chain structure of FIG. 5, and FIG. 8 is a partial three-dimensional view of the chain structure of FIG. 7. Referring to FIG. 7, in the present embodiment, the fixed frame 152 includes a main body 152a and a plurality of position-limiting arms 152b. The position-limiting arms 152b extend out from the main body 152a. Each of the first segments 142 (shown in dot lines) is confined on the main body 152a by the position-limiting arms 152b, so as to fix the cable set 140 (shown in FIG. 2). Moreover, referring to FIG. 7 and FIG. 8, the chain structure 154 includes a plurality of pivoted elements 154a. The pivoted elements 154a are sequentially pivoted to form the chain structure 154, so as to facilitate bending. Each of the pivoted elements 154a has at least a position-limiting arm 154b, and each of the second segments 144 (shown in dot lines) is confined on the pivoted elements 154a by the first position-limiting arms 154b, so as to fix the cable set 140 (shown in FIG. 2). Moreover, each of the pivoted elements 154a has a pivoted portion 154c and a pivoted hole 154d located on the pivoted portion 154c. The pivoted portion 154c of each of the pivoted elements 154a is overlapped with the pivoted portion 154c of the other pivoted element 154a, so that the pivoted hole 154d of each of the pivoted elements 154a is aligned to the pivoted hole 154d of the other pivoted element 154a, and therefore the two adjacent pivoted elements 154a can be pivotally connected through the pivoted holes 154d. 
Referring to FIG. 4 and FIG. 5, in the present embodiment, the cable arranging module 150 further includes a connection rode 156. One end of the connection rod 156 is pivotally connected to the electronic module 120, and another end of the connection rod 156 is pivotally connected to the chain structure 154. An angle between the connection rode 156 and the chain structure 154 can be suitably designed, so that a user can easily operate the whole structure between states as that shown in FIG. 4 and FIG. 5.
In summary, the cable arranging module of the invention is formed by the fixed frame and the chain structure, and the cable set is fixed to the fixed frame and the chain structure. When the electronic module is moved relative to the chassis, a part of the cable set can be curved along with the chain structure, so that a whole structure thereof may have enough degrees of freedom. One end of the chain structure is connected to the electronic module to maintain a relative position between the tail end of the cable set and the electronic module, so as to prevent the cable set from falling off from the electronic module due to movement of the electronic module.
It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the invention without departing from the scope or spirit of the invention.
