[0003] Nowadays, when wiring distribution cabinets, high-strength and high-tensile plastic cable ties are usually used to bundle the connecting wires, or multiple arc-shaped fixing seats are set in the cabinet. However, the cable ties generally have a large binding force on the connecting wires when used, which can easily damage the surface of the connecting wires. The arc-shaped fixing seats generally require the connecting wires to be pushed into the seats with force, and there is an interference fit during the connection process, which can also easily cause damage to the connecting wires. Moreover, when the staff needs to inspect and replace the lines in the cabinet, the ends of the connecting wires are connected to the female connectors on the electronic components in the distribution cabinet through the connecting ends. At this time, the ends of the connecting wires cannot be pulled out of the cable ties or the arc-shaped fixing seats, and the staff needs to cut the cable ties or pull the connecting wires out of the arc-shaped fixing seats, which brings inconvenience to the maintenance work and makes it difficult to achieve the ideal use effect.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0027] See also Figure 1-Figure 9 In an embodiment of the present invention, a wiring structure of a power distribution cabinet is provided in the cabinet 1 and is located between a first component group 101 and a second component group 102 in the cabinet 1, and is used to fix a connection line between the first component group 101 and the second component group 102; The distribution cabinet wiring structure includes: A horizontal plate 4, one end of which is fixed to the inner wall of the cabinet 1 by a fastener 3; A plurality of pre-clamping mechanisms are provided on the transverse plate 4 at equal distances along the length direction of the transverse plate 4; A covering fixing mechanism, wherein a plurality of groups are equidistantly arranged on the transverse plate 4 along the length direction of the transverse plate 4, the covering fixing mechanism is located on one side of the pre-clamping mechanism, and the covering fixing mechanism is connected to two groups of ejection driving mechanisms, the ejection driving mechanisms are connected to a driven limiting mechanism arranged in the cabinet body 1 and located at one end of the transverse plate 4 away from the fastener 3, and the driven limiting mechanism cooperates with the hinged cabinet door 2 on the cabinet body 1; Among them, when the hinged cabinet door 2 switches from an open state to a closed state, the driven limit mechanism can cooperate with the driven limit mechanism to prompt the ejection drive mechanism to drive the covering fixing mechanism to perform a fixing action on the connecting line located on the horizontal plate 4, and vice versa, the covering fixing mechanism contacts the fixing action of the connecting line.

[0028] Specifically, the hinged cabinet door 2 is in an open state. When wiring is performed, the pre-clamping mechanism can be used to preliminarily connect the connecting wire to the horizontal plate 4. At this time, the connection between the connecting wire and the horizontal plate 4 is not stable, so that it is convenient for the staff to adjust the connecting wire. When the connection line is arranged and the hinged cabinet door 2 is closed, the hinged cabinet door 2 will cooperate with the driven limiting mechanism, and the ejection drive mechanism is triggered to drive the covering and fixing mechanism to perform a flipping action, thereby enclosing the horizontal plate 4, so that the connection line is further fixed, thereby avoiding the reliability of the electrical connection between the first component group 101 and the second component group 102 during the operation of the distribution cabinet.

[0029] Please refer again Figure 5 , Figure 6 as well as Figure 7 , a receiving seat 5 arranged in an arc shape is fixed on the horizontal plate 4, and the pre-clamping mechanism includes two groups of opposing pressure components respectively located at the two ends of the receiving seat 5, and the opposing pressure components include two groups of sliding yielding parts arranged oppositely. A first guide groove 401 is provided on the horizontal plate 4, and the sliding yielding part includes two guide shafts 7 fixed in the first guide groove 401, a slider 8 slidably connected to the two guide shafts 7, and a pre-tightening member 6 fixedly connected to the slider 8. Among them, the outer circumferences of the two guide shafts 7 are respectively sleeved with a first cylindrical spring 9, one end of the first cylindrical spring 9 is connected to the slider 8, and the other end is connected to the inner wall of the first guide groove 401, and the pre-tightening member 6 includes a connected inclined portion 601 and an arc portion 602.

[0030] Further, when the hinged cabinet door 2 is in an open state, the staff can place the connecting wire on the receiving seat 5 when arranging the connecting wire between the first element group 101 and the second element group 102, and then align the connecting wire on both sides of the receiving seat 5 between the two pre-tightening members 6, so that the connecting wire contacts the inclined portion 601, and then the connecting wire is pressed toward the cross plate 4, so that the connecting wire causes the pre-tightening member 6 to give way through the inclined portion 601. Specifically, the pre-tightening member 6 drives the slider 8 to slide on the two guide shafts 7, and the first columnar spring 9 is compressed. After the connecting wire is pressed between the two opposite arc-shaped portions 602, the connecting wire can be initially clamped under the elastic support of the first columnar spring 9, so that the connecting wire and the cross plate 4 remain relatively stationary. As the connection line is arranged, when the staff needs to adjust the connection position, they only need to directly hook the connection line out from between the two opposite arc-shaped parts 602, which is convenient and quick to operate and is conducive to the rapid advancement of the wiring work; It should be pointed out that the pre-clamping mechanism only serves as a preliminary limit for the connecting wires in order to facilitate the wiring work of the staff. Therefore, the tightening force of the pre-tightening member 6 on the connecting wires is not great, and the connecting wires are easily detached from the cross plate 4. It is difficult to avoid the loosening of the connection between the connecting wires and the first component group 101 and the second component group 102 during the long-term operation of the distribution cabinet. For this reason, the covering and fixing mechanism is provided to reliably fix the connecting wires after closing the hinged cabinet door 2.

[0031] The covering and fixing mechanism includes a rotating shaft 11 rotatably mounted on the side of the horizontal plate 4 facing the receiving seat 5 and a plurality of covering parts 10 fixedly mounted on the rotating shaft 11. The covering parts 10 are arranged in an arc shape and correspond to the position of the receiving seat 5. The two ends of the rotating shaft 11 are respectively connected to the two groups of the ejection drive mechanisms through a group of transmission components.

[0032] The transverse plate 4 is also provided with a second guide groove 402, and the transmission assembly includes a follower plate 12 slidably arranged in the second guide groove 402 and a sleeve 13 fixedly installed on the follower plate 12 facing the rotating shaft 11, and the sleeve 13 is slidably fitted with the rotating shaft 11; Among them, a protrusion is fixedly provided on the inner wall of the sleeve 13, and a sliding groove 1101 adapted to the protrusion is provided on the outer wall of the rotating shaft 11. The sliding groove 1101 is spirally arranged on the rotating shaft 11, and the protrusion extends into the sliding groove 1101 and is slidably connected with the rotating shaft 11.

[0033] When the wiring is completed and the hinged cabinet door 2 is closed, the hinged cabinet door 2 will cooperate with the driven limiting mechanism and the ejection drive mechanism will be triggered. Then, the ejection drive mechanism will drive the follower plate 12 to slide toward the inside of the second guide groove 402. Correspondingly, the follower plate 12 drives the sleeve 13 to slide toward the covering member 10 on the rotating shaft 11, and the convex column on the inner wall of the sleeve 13 moves linearly along the axial direction of the rotating shaft 11, and slides with the rotating shaft 11 through the slide groove 1101, thereby causing the rotating shaft 11 to rotate, and the rotating shaft 11 drives multiple covering members 10 to deflect toward the receiving seat 5, and the connecting line is firmly positioned between the covering member 10 and the receiving seat 5.

[0034] Furthermore, in order to enhance the effect of the covering member 10 and the receiving seat 5 on positioning the connection line, anti-slip pads are provided on the inner walls of the covering member 10 and the receiving seat 5 .

[0035] Please refer again Figure 8 and Fig. 9A slide rail 24 is fixed on the inner wall of the cabinet 1, and the driven limiting mechanism includes a movable seat 23 slidably embedded in the slide rail 24, two vertical arms 22 fixed to the movable seat 23 away from the slide rail 24, and a limiting plate 26 cooperating with the ejection drive mechanism is fixed at each end of the vertical arm 22; Among them, an elastic telescopic rod 25 is also installed in the cabinet body 1, and the movable end of the elastic telescopic rod 25 is fixed to the vertical arm 22. The limiting plate 26 is connected to a driven wheel 21 through a connecting column 28 on the side facing the hinged cabinet door 2, and the driven wheel 21 cooperates with the hinged cabinet door 2.

[0036] The limiting plate 26 is provided with a trapezoidal groove, and the groove includes a first groove section 2601, a second groove section 2602, a third groove section 2603 and a fourth groove section 2604 which are connected to each other. The fourth groove section 2604 is an inclined groove. A one-way limiting member 27 is hinged in the groove. The one-way limiting member 27 is located at the connection between the fourth groove section 2604 and the first groove section 2601, and is also connected to a torsion spring arranged in the groove.

[0037] Regarding the installation of the one-way limit member 27, taking the upper limit plate 26 as an example, the one-way limit member 27 can only rotate upward in the groove but not downward, and during the upward rotation process, the torsion spring is deformed to facilitate the reverse deflection and reset of the one-way limit member 27.

[0038] The ejection drive mechanism includes an assembly tube 16 fixed on the inner wall of the cabinet 1 and a vertical rod 17 slidably fitted with the assembly tube 16, the vertical rod 17 is fixed with a boss 19 slidably arranged inside the assembly tube 16, and a second cylindrical spring 20 is connected between the boss 19 and the inner wall of the assembly tube 16, and the second cylindrical spring 20 is sleeved on the outer periphery of the vertical rod 17. Among them, the head end of the vertical rod 17 is provided with a rolling wheel 18, the rolling wheel 18 extends into the groove, and the tail end is fixedly connected with a cross arm 15, the cross arm 15 is fixed with the follower plate 12, and the end of the cross arm 15 away from the vertical rod 17 is slidably fitted with a guide rail 14 fixed on the inner wall of the cabinet 1.

[0039] It should be emphasized that when the hinged cabinet door 2 is in an open state (i.e., the state shown in the figure), under the elastic support of the spring inside the elastic telescopic rod 25, the driven wheel 21 extends out of the cabinet body 1, and the rolling wheel 18 is located at the connecting inflection point of the first slot segment 2601 and the fourth slot segment 2604; When the wiring is completed and the hinged cabinet door 2 is closed, the driven wheel 21 will roll on the inner wall of the hinged cabinet door 2. Under the guidance of the vertical arm 22, the movable seat 23 and the slide rail 24, the hinged cabinet door 2 causes the connecting column 28 to push the limiting plate 26 to move horizontally in the cabinet body 1 through the driven wheel 21. Accordingly, the spring inside the elastic telescopic rod 25 is compressed, and the first slot section 2601 will pass through the rolling wheel 18. When the second slot section 2602 reaches the rolling wheel 18, the second column 2602 The spring 20 will rebound, and the rolling wheel 18 will roll along the second slot section 2602 to the connection between the second slot section 2602 and the third slot section 2603, so that the vertical rod 17 pushes the cross arm 15 to slide on the guide rail 14 close to the cross plate 4, and the cross arm 15 drives the follower plate 12 to slide toward the inside of the second guide groove 402, so that the convex column on the inner wall of the sleeve 13 and the slide groove 1101 are slidably matched, and the multiple covering parts 10 are deflected toward the receiving seat 5 to cover the connection line. Position; When the hinged cabinet door 2 is opened, the spring inside the elastic telescopic rod 25 will rebound, causing the limit plate 26 to move horizontally and reset. Accordingly, the driven wheel 21 re-extends into the outside of the cabinet body 1. During this process, the third slot section 2603 and the fourth slot section 2604 will pass through the rolling wheel 18 in sequence. Since the fourth slot section 2604 is an inclined slot, the rolling wheel 18 will give way during the process of the fourth slot section 2604 passing through the rolling wheel 18. Specifically, the vertical rod 17 drives the cross arm 15 to move away from the cross plate 4 and reset. The second cylindrical spring 20 is compressed, and the cross arm 15 drives the follower wheel 21 to move horizontally and reset. The movable plate 12 slides toward the outside of the second guide groove 402, and the rotating shaft 11 drives the covering member 10 to deflect away from the connecting line, releasing the covering positioning of the connecting line, and when the rolling wheel 18 passes through the one-way limiting member 27, the one-way limiting member 27 will be prompted to rotate toward the first groove section 2601, and the rolling wheel 18 can smoothly return to the first groove section 2601, and then the one-way limiting member 27 will reversely deflect and reset under the rebound effect of the torsion spring, and when the hinged cabinet door 2 is closed next time, the one-way limiting member 27 can support the rolling wheel 18 to prevent the rolling wheel 18 from entering the fourth groove section 2604; It should be pointed out that the elastic telescopic rod 25 is a common structure currently available. Specifically, it includes a guide cylinder fixed on the inner wall of the cabinet 1 and a cylindrical rod slidably fitted with the guide cylinder. The cylindrical rod is fixed to the vertical arm 22, and the two ends of the spring inside it are respectively connected to the inner wall of the guide cylinder and the cylindrical rod. In addition, compared with the second cylindrical spring 20, the elastic potential energy of the spring inside the elastic telescopic rod 25 is larger.

[0040] As another embodiment of the present invention, a power distribution cabinet is also proposed, which includes the wiring structure. Therefore, in actual use, the pre-clamping mechanism can be used to preliminarily position the connecting wires during wiring. After the hinged cabinet door 2 is closed, the covering 10 can firmly fix the connecting wires to avoid loosening of the connecting wires during daily operation. After the cabinet door is opened, the covering 10 can automatically release the fixing state of the connecting wires, which is convenient for staff to inspect or replace the lines. At this time, the pre-clamping mechanism can also maintain the initial wiring state.

[0041] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0042] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
