[0041] In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0042] Example 1:

[0043] The utility model embodiment 1 provides a cable assembly protection device, such as Figure 1 and Figure 2As shown, it includes: a docking seat 1, a first torsion spring hinge 2, a first wiring board 3, a second torsion spring hinge 4, a second wiring board 5, a third torsion spring hinge 6 and a fixing seat 7, wherein:

[0044] One end of the first wiring board 3 is axially connected to the docking seat 1 through the first torsion spring hinge 2, the other end of the first wiring board 3 is axially connected to one end of the second wiring board 5 through the second torsion spring hinge 4, and the other end of the second wiring board 5 is axially connected to the fixed seat 7 through the third torsion spring hinge 6. The fixed seat 7 is set on the inner wall of the cabinet 101; the first wiring board 3 and the second wiring board 5 are used for routing cables 8, and the docking seat 1 is used to connect to the host socket board 102.

[0045] The first torsion spring hinge 2, the second torsion spring hinge 4 and the third torsion spring hinge 6 are used to receive external force to unfold the first wiring board 3 and the second wiring board 5; and are also used to restore deformation to fold the first wiring board 3 and the second wiring board 5 together.

[0046] like Figure 1 and Figure 2 As shown, in this embodiment, the first wiring board 3 and the second wiring board 5 are both long rectangular strips. The first wiring board 3 and the second wiring board 5 can be the same model or size. The first wiring board 3 and the second wiring board 5 are both used for routing cables 8. At the same time, the cables 8 can be fixed to the first wiring board 3 and the second wiring board 5 by cable ties.

[0047] In this embodiment, when the cable 8 does not need to be connected to the host socket board 102, in order to make the cable 8 and each wiring board occupy as little space as possible inside the cabinet 101, the first wiring board 3 and the second wiring board 5 need to be in a folded state. Figure 3 As shown, when the first torsion spring hinge 2, the second torsion spring hinge 4 and the third torsion spring hinge 6 are not subjected to external force, the angle between the first wiring plate 3 and the docking seat 1 can be 90°±5°, the angle between the first wiring plate 3 and the second wiring plate 5 can be 10°±5°, and the angle between the second wiring plate 5 and the fixing seat 7 can be 170°±5°.

[0048] like Figure 1As shown, when the cable 8 needs to be stretched out and docked with the host socket plate 102, the docking seat 1 is pulled toward the host socket plate 102, and the first torsion spring hinge 2, the second torsion spring hinge 4 and the third torsion spring hinge are twisted under the action of external force. At this time, the angle between the first wiring plate 3 and the docking seat 1 increases, the angle between the first wiring plate 3 and the second wiring plate 5 increases, and the angle between the second wiring plate 5 and the fixed seat 7 decreases, so that the first wiring plate 3 and the second wiring plate 5 are unfolded. At the same time, the docking seat 1 is moved to the position of the host socket plate 102, so that the cable 8 does not need to be stretched out for a long time to dock with the host socket plate 102. At the same time, the docking seat 1 and the host socket plate 102 can be fixed by screws. The cable 8 is stretched out a small section to dock with the host socket plate 102. The first torsion spring hinge 2, the second torsion spring hinge 4 and the third torsion spring hinge 6 are maintained in a twisted state through the docking and fixation between the host socket plate 102 and the docking seat 1. Figure 3 As shown, when the host is withdrawn from the cabinet 101, it is necessary to release the connection between the cable 8 and the host socket plate 102. At this time, the docking seat 1 is no longer pulled by the host socket plate 102. The first torsion spring hinge 2, the second torsion spring hinge 4 and the third torsion spring hinge 6 drive the docking seat 1, the first wiring plate 3 and the second wiring plate 5 to resume rotation along with each torsion spring hinge due to their own elastic restoring force. The first wiring plate 3 and the second wiring plate 5 drive the cable 8 to resume its folded state.

[0049] Through the above design, when the cable 8 does not need to be docked with the host socket plate 102, the cable 8 is stored on the first wiring plate 3 and the second wiring plate 5 folded together, so that the space occupied by the cable 8 inside the cabinet 101 is as small as possible, avoiding occupying too much space inside the cabinet 101. At the same time, the total length of the first wiring plate 3 and the second wiring plate 5 can be longer, so that more parts of the cable 8 can be stored on the wiring plate, further reducing the interference of the cable 8 on the inside of the cabinet 101. When the cable 8 needs to be docked with the host socket plate 102, by folding the first wiring plate 3 and the second wiring plate 5 is unfolded, so that the cable 8 extends to the vicinity of the host socket plate 102, avoiding the need to stretch out too much cable 8 for docking. At the same time, the extension path of the cable 8 is fixed to avoid mixing with other devices inside the cabinet 101; when the host needs to be withdrawn from the cabinet 101, after the cable 8 and the host socket plate 102 are separated, the first wiring plate 3 and the second wiring plate 5 drive the cable 8 to return to the folded state under the action of each torsion spring hinge, thereby realizing the storage and protection of the cable 8 and avoiding the cable 8 from occupying too much space. There is no need to manually arrange and adjust the cable 8, which further improves convenience.

[0050] Furthermore, in this embodiment, when the docking seat 1 is pulled out and docked and fixed with the host socket plate 102, since there may be a certain distance between the docking position of the cable 8 and the host socket plate 102 and the position where the docking seat 1 and the host socket plate 102 are fixed, it is necessary to stretch out a section of the cable 8 for docking with the host socket plate 102. When the host is withdrawn from the cabinet 101 and the cable 8 is no longer docked with the host socket plate 102, the stretched section of the cable 8 cannot be stored. This section of the cable 8 may interfere with other devices in the cabinet 101, causing damage to the cable 8 or other devices. Therefore, this embodiment also involves the following designs:

[0051] like Figure 1-Figure 4 As shown, the cable assembly protection device further includes a wire take-up device 9, which is disposed on the docking seat 1. The wire take-up device 9 includes a plurality of spring wire take-ups, which are used for automatic wire take-up.

[0052] The cable take-up device 9 includes a housing 91 , a first port 92 , and a second port 93 . The first port 92 is located on a side of the housing 91 facing the first wiring board 3 , and the second port 93 is located on a side of the housing 91 facing away from the second wiring board 5 .

[0053] The interior of the shell 91 is used for winding the cable 8, the first port 92 is used for leading out one end of the cable 8 and extending it to the first wiring board 3 and the second wiring board 5, and the second port 93 is used for leading out the other end of the cable 8.

[0054] In this embodiment, the cable 8 is led out from the inside of the cabinet 101 and is stored along the first wiring board 3 and the second wiring board 5. When passing through the wire take-up device 9, the cable 8 is introduced into the wire take-up device 9 from the first port 92, and part of the cable 8 is coiled inside the wire take-up device 9. The cable 8 with an interface at the other end is led out from the second port 93. When it is necessary to connect the cable 8 to the host socket board 102, the cable 8 is pulled out from the host socket board 102 and connected to the host socket board 102 through the interface of the cable 8. When the cable 8 and the host socket board 102 are disconnected, Except for the cables 8 with connectors, the rest of the cables 8 will be retracted into the shell 91 by the cable take-up 9 and coiled by various spring cable take-ups. Each of the spring cable take-ups is provided with a ruler spring, and the cables pulled out from the spring cable take-up are automatically retracted and coiled by the restoring force of the ruler spring to prevent the stretched cables 8 from hanging outside and causing squeezing and interference with other devices in the cabinet 101. In this embodiment, since the spring cable take-up is an existing structure, no corresponding drawings are provided in this embodiment.

[0055] Furthermore, in this embodiment, the first wiring board 3 and the second wiring board 5 need to be restored and folded by various torsion spring hinges. Therefore, this embodiment involves the following designs for the torsion spring hinges:

[0056] like Figure 5 As shown, a torsion spring 24 is correspondingly provided in each of the first torsion spring hinge 2 , the second torsion spring hinge 4 and the third torsion spring hinge 6 .

[0057] like Figure 2 and Figure 5 As shown, taking the first torsion spring hinge 2 as an example, the first torsion spring hinge 2 includes: a central axis 23 and a torsion spring 24, wherein: the torsion spring 24 is sleeved on the central axis 23, the docking seat 1 and the central axis 23 are axially connected, and the docking seat 1 and one end of the torsion spring 24 are in contact with each other, one end of the first wiring board 3 is axially connected to the central axis 23, and one end of the first wiring board 3 is in contact with the other end of the torsion spring 24. When the two wiring boards are folded together, under the action of the torsion spring 24, the docking seat 1 and the first wiring board 3 remain as shown. Figure 3 when the docking station 1, the torsion spring 24 receives external force, the docking station 1 and the first wiring board 3 is transformed into such as Figure 1 status.

[0058] In this embodiment, the structures of the second torsion spring hinge 4 and the third torsion spring hinge 6 are consistent with those of the first torsion spring hinge 2, and both include a central axis 23 and a torsion spring 24, wherein the central axis 23 of the second torsion spring hinge 4 is connected to the first wiring board 3 and the second wiring board 5, respectively, and the central axis 23 of the third torsion spring hinge 6 is connected to the second wiring board 5 and the docking seat 1, respectively; Figure 5 As shown, after the torsion spring 24 is sleeved on the central axis 23, there is still a lot of space at both ends of the central axis 23, which is used to connect with the devices on both sides of the torsion spring hinge; the rest of the internal structure refers to the above-mentioned first torsion spring hinge 2, and will not be elaborated here.

[0059] Furthermore, in order to ensure the stability of the routing and storage of the cable 8 on the first routing plate 3 and the second routing plate 5 and to prevent the cable 8 from falling out of the routing plates, this embodiment also involves the following designs:

[0060] like Figure 6 As shown, the first wiring board 3 includes a bottom plate 31 and at least two side plates 32, wherein the two side plates 32 are respectively arranged on both sides of the bottom plate 31. The bottom plate 31 is used to place the cables 8, and the side plates 32 are used to limit the position of the cables 8 placed on the bottom plate 31. The bottom plate 31 and the side plates 32 are both provided with a plurality of through holes 33 arranged in an array.

[0061] In this embodiment, the two side panels 32 are used to prevent the cables 8 from escaping from the sides of the base plate 31. When the cables 8 are routed along the first and second routing plates 3 and 5, cable ties can be used to secure the cables 8 to the base plate 31. The through holes 33 are used to pass the cable ties through to secure the cables 8. The second routing plate 5 has the same structure as the first routing plate 3. The structure of the second routing plate 5 can be referred to as the structure of the first routing plate described above, and will not be described in detail here.

[0062] In this embodiment, the length of the bottom plate 31 is 300±5 cm, and the width of the bottom plate 31 is 100±5 cm; wherein, the length of the bottom plate 31 can be 295 cm, 300 cm or 305 cm, and the width of the bottom plate 31 can be 95 cm, 100 cm or 105 cm.

[0063] Furthermore, the docking station 1 needs to be fixed to the host socket board 102. This embodiment provides the following design for the docking station 1:

[0064] like Figure 7 As shown, the docking seat 1 is provided with an avoidance opening 11, and a first screw hole 12 is provided on the end surface of the docking seat 1 facing away from the first torsion spring hinge 2, and the first screw hole 12 leads to the inner side wall of the avoidance opening 11; the first screw hole 12 is used to correspond to the screw hole on the host socket plate 102 and to cooperate with the screws to achieve fixed docking between the docking seat 1 and the host socket plate 102.

[0065] Furthermore, the fixing base 7 needs to be fixed to the inner wall of the cabinet 101, and the second wiring board 5 needs to have sufficient movable space relative to the third torsion spring hinge 6. Therefore, the third torsion spring hinge 6 cannot be directly set on the inner wall of the cabinet 101. Therefore, this embodiment also involves the following design:

[0066] like Figure 8 As shown, the fixing base 7 includes a docking portion 71 and a transition portion 72. One end of the transition portion 72 is connected to the third torsion spring hinge 6, and the docking portion 71 is located at the other end of the transition portion 72. The docking portion 71 is configured to be fixedly docked with the inner wall of the cabinet 101. A second screw hole 73 is provided on the docking portion 71. The second screw hole 73 is configured to correspond to a screw hole on the inner wall of the cabinet 101 and, through screw engagement, achieves fixed docking between the docking portion 71 and the inner wall of the cabinet 101. In this embodiment, the angle between the docking portion 71 and the transition portion 72 can be 90±5 degrees.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
