DETAILED DESCRIPTION

[0018] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear in the following, they only indicate that the upper, lower, left and right directions are consistent with the drawings themselves, and do not limit the structure.

[0019] like Figure 1 , Figure 6 As shown, an electrical panel cabinet provided in this embodiment includes a main frame 1, a movable frame 2, a hinge 3, a locking member 4, a fixing seat 6 for arranging a wiring harness 5, a first binding member 7 and a second binding member 8. The main frame 1 has a length direction X and a width direction Y.

[0020] like Figure 1 As shown, the movable frame 2 is hinged to both sides of the main frame 1 in the X direction through hinges 3, and the movable frame 2 can rotate along the main frame 1 to form a first position and a second position.

[0021] The inner surface of the movable frame 2 is set as the second operation surface 24 for wiring, and the inner surface of the main frame 1 is set as the first operation surface 16 for wiring. When in the first position, the two movable frames 2 are unfolded so that the two second operation surfaces 24 are horizontal with the first operation surface 16. When in the second position, the two movable frames 2 are folded so that the two second operation surfaces 24 are perpendicular to the first operation surface 16 (such as Figure 2 as shown).

[0022] The electrical panel cabinet needs to be provided with a skin on the outer surface of the main frame 1 and the movable frame 2, and a cabinet door on the movable frame 2 to protect the internal components and increase the aesthetics. In the drawings of this embodiment, the skin and the cabinet door are omitted. Figure 2 As shown, the main frame 1 includes a top frame 11 , a bottom frame 12 , a column 13 , a first plug hole 14 , a first panel 15 and a first operating surface 16 .

[0023] like Figure 3 As shown, the top frame 11 and the bottom frame 12 are arranged at intervals up and down, and both of them are hollow rectangular frames. The columns 13 connect the top frame 11 and the bottom frame 12 around the top frame 11 and the bottom frame 12. The cross section of the column 13 is C-shaped, and a plurality of first jacks 14 are provided on the three side walls of the C-shape. The C-shaped openings on the two columns 13 in the X direction are arranged away from each other. A first panel 15 is connected between the two columns 13 in the X direction, and the first panel 15 is arranged on one side of the Y direction, and a hinge 3 is provided on the column 13 on this side. Electronic components will be installed on the inner surface of the first panel 15, and wiring will also be performed at the same time. Therefore, the inner surface of the first panel 15 is the first operating surface 16.

[0024] like Figure 2 As shown, the movable frame 2 includes a side frame 21, a second socket 22, a second panel 23 and a second operating surface 24. The side frame 21 is an upright rectangular frame, and the cross section of the upright main rod is rectangular. A plurality of second sockets 22 are provided on the four side walls of the upright rod. The plurality of second sockets 22 and the plurality of first sockets 14 have corresponding hole spacings so that the locking member 4 can be installed. A plurality of second panels 23 are installed on the inner side of the side frame 21. The second panels 23 are provided for mounting components, so the inner surface of the second panel 23 is a second operating surface 24 for wiring. The second panel 23 is connected between two upright poles.

[0025] like Figure 2As shown, the cross-sections of the first panel 15 and the second panel 23 are both in the shape of "ji". First, raising the installation surface inside the electrical cabinet facilitates the installation of electrical components. Second, the "ji"-shaped panel greatly increases its structural strength, which is conducive to the realization of stable installation. Third, the "ji"-shaped panel has two horizontal end plates, which are placed on the inner surface of the column or vertical rod, facilitating the installation of the panel.

[0026] As Figure 2 shown, the hinge 3 is a common structure, with a part installed on the column 13 of the main frame 1 and a part installed on the side frame 21. In the second position, the side frame 21 is placed inside the side part of the main frame 1, and then locked by inserting the locking part 4 into the corresponding first jack 14 and second jack 22. The locking part 4 can be a screw with a knob, combined with a nut for locking.

[0027] As Figure 4 shown, after the movable frame 2 is unfolded, the two second operating surfaces 24 and the first operating surface 16 are both horizontal. Thus, wiring operations can be directly carried out on the unfolded operating surface, greatly increasing the wiring space. The wire harness formed by planar wiring is as Figure 5 shown.

[0028] As Figure 6 shown, during wiring, according to the direction of the wire harness 5, the fixing seats 6 are installed on the corresponding operating surfaces, and one fixing seat 6 is installed in the cross-region of the first operating surface 16 and the second operating surface 24 respectively. The fixing seats 6 on the operating surface are used to clamp the first binding member 7, and the two fixing seats 6 in the cross-region are used to install the second binding member 8.

[0029] As Figure 7 shown, the fixing seat 6 includes a mounting plate 61, support feet 62, fixing holes 63, slots 64 and limiting holes 65. The support feet 62 are connected to one side of the mounting plate 61 at intervals. The fixing holes 63 are arranged between the two support feet 62. The mounting plate 61 is installed on the corresponding operating surface by installing screws in the fixing holes 63. The support feet 62 are provided with vertically extending slots 64, and the slots 64 penetrate through the side of the support feet 62 away from the mounting plate 61. A horizontally penetrating limiting hole 65 is provided on one side of the support feet 62 forming the slot 64. In this embodiment, the two limiting holes 65 penetrate towards the sides away from each other.

[0030] As Figure 8 shown, the first binding member 7 includes a first buckle 71, a third jack 72, a first binding band 73, a pin 74 and a second binding band 75.

[0031] The first binding strap 73 is connected to the second binding strap 75. A latch 74 is provided on the inner surface of the first binding strap 73, and the latch 74 is close to the end of the first binding strap 73. The cross section of the latch 74 is an L-shape bent toward the second binding strap 75.

[0032] A plurality of third jacks 72 are arranged on the second strap 75. In the initial position, an installation cavity is formed between the first strap 73 and the second strap 75, and the wiring harness is placed in the cavity. First, the second strap 75 is wound around the wiring harness, and then the first strap 73 is wound around the second strap 75. Finally, the latch 74 is clamped into the third jack 72 at the corresponding position, and locked with the third jack 72 through the hook at the end of the L-shape. The structure in which the first strap 73 and the second strap 75 are interlocked can fix the wiring harness 5 in an embracing manner, and the embracing force can be adjusted.

[0033] The outer surface of the connection between the first strap 73 and the second strap 75 (the side away from the installation cavity) is provided with the first buckle 71, and the first buckle 71 is two and is adapted to the support leg 62. The ends of the two first buckles 71 are both provided with hooks, and the two hooks extend away from each other.

[0034] like Fig. 9 As shown, when the first binding member 7 and the fixing seat 6 are installed, the first buckle 71 is inserted into the slot 64 one by one until the hook on the first buckle 71 extends from the limiting hole 65 to achieve locking. When it is necessary to disassemble, the hook is separated from the limiting hole 65.

[0035] like Fig.10 As shown, the second binding member 8 includes a slot body 81 with an arc-shaped wall, and a plurality of binding holes 85, a curved hole 84 and a curved notch 83 are arranged on the side wall of the slot body 81. The curved hole 84 is placed in the middle of the slot body 81, and the curved notch 83 is placed at both ends of the slot body 81 in the radial direction and adjacent to the edge, and the curved notch 83 is arranged corresponding to the curved hole 84. The plurality of binding holes 85 are placed at both ends of the slot body 81 in the axial direction, and the plurality of binding holes 85 are arranged at both ends of the slot body 81 in the radial direction. A second buckle 82 is provided on the side of the slot body 81 away from the center of the arc-shaped wall, and the structure of the second buckle 82 is the same as that of the first buckle 71, and is connected to the fixing seat 6.

[0036] like Fig.11 , Fig.12 As shown, both ends of the second binding member 8 can be bent under the action of the bending hole 84 and the bending notch 83 to adaptively bend the wire harness 5 spanning the first operating surface 16 and the second operating surface 24 after the movable frame 2 is folded.

[0037] like Fig.10As shown, a mounting cavity is formed in the slot body 81 of the arc-shaped wall for placing the wire harness 5. The binding holes 85 are arranged in two rows at the same end, and two binding holes 85 in the same radial direction are bound by a cable tie, so that the wire harness is fixed through the combined action of the slot body 81 and the cable tie. The cable tie is arranged at both ends of the slot body 81, which not only plays a better fixing role for the wire harness, but also does not interfere with the bending of the slot body 81. The cable tie and the slot body 81 fix the wire harness 5 in an embracing manner, and the size of the embracing force is adjustable.

[0038] When it is necessary to assemble the components and wiring harnesses in the electrical panel cabinet, the locking piece 4 is opened, and the movable frames 2 on the left and right sides are unfolded and placed horizontally, so that the electrical installation surface is no longer limited to the cubic range surrounded by the main frame, but a new open space is formed, forming multiple operating surfaces, which is convenient for multiple operators to work at the same time and shortens the production cycle.

[0039] For the wiring process, since the electrical panel cabinet can be unfolded, it can provide a complete flat surface for operation during the assembly process, and the pre-wired wire harness is also placed flat before installation, which makes it convenient to install the pre-wired wire harness directly on the panel of the panel cabinet.

[0040] The present invention also provides a wiring method for the above-mentioned electrical panel cabinet, comprising the following steps: Step S1 : forming wiring paths on the first operating surface 16 and the two second operating surfaces 24 according to the wiring structure.

[0041] Step S2, unfold the two second operating surfaces 24 and place them in the first position.

[0042] Step S3, according to the wiring path, multiple fixing seats 6 are installed at corresponding positions on the second operating surface 24, and the first binding member 7 is installed on the fixing seats 6. Multiple fixing seats 6 are installed at the position where the wiring harness 5 crosses the first operating surface 16 and the second operating surface 24, and the second binding member 8 (such as Fig.13 as shown).

[0043] Step S4, the pre-wired cables are placed on the first operating surface 16 and the second operating surface 24 respectively, and fixed at the corresponding first binding members 7 and second binding members 8. The cables are connected, and the ends of the cables are connected to the electrical components on the first panel 15 and the second panel 23 at the corresponding positions.

[0044] Step S5, debug the wiring, the debugging content includes the response of each electronic component, the connection and disconnection of the line, etc. If the debugging result meets the design requirements, proceed to the next step, if the debugging result does not meet the design requirements, find the fault and eliminate it.

[0045] Step S6, fold the movable frame 2 to the second position and lock it by the locking member 4. The wiring is completed.

[0046] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention.
