[0008] In order to effectively restrain the main electrical wires to prevent them from moving, wire harness components are respectively arranged on the two side walls of the inner cavity of the electrical box.

[0011] Furthermore, a moving groove is provided on the moving frame, and the lower end of the moving plate is slidably arranged in the moving groove.

[0012] Specifically, the limiting assembly includes a support plate, which is fixed on the upper surface of the connecting plate, a protective shell is fixedly connected to the top of the support plate, a fixed frame is fixed on the side of the protective shell away from the support frame, a fixed rod is fixed inside the fixed frame, a moving rod is slidably provided on the fixed rod, an arc block is fixed at the end of the moving rod, a first spring is sleeved on the outer periphery of the moving rod, one end of the first spring is connected to the fixed rod, and the other end of the first spring is connected to the arc block.

[0013] Furthermore, a circular groove is provided inside the protective shell, the wire connector is located inside the circular groove, and a clamping block is fixedly connected to the top of the wire connector.

[0014] Specifically, the wiring harness assembly includes a fixed guide rail fixed on the side wall of the inner cavity of the electrical box, the upper surface of the fixed guide rail is threadedly connected to a threaded rod, the top of the threaded rod is fixedly connected to a rotating block, the bottom of the threaded rod is fixedly connected to a first magnetic block, and a second magnetic block is slidably provided inside the fixed guide rail, and the second magnetic block is magnetically matched with the first magnetic block.

[0017] Furthermore, the four corners of the electrical component are respectively provided with protrusions, and the protrusions are fixed to the fixing plate by screws.

[0018] The beneficial effects of the present invention are:

[0019] 1. The arc-shaped clamping plate in the clamping assembly helps to clamp and fix the wires in the electrical box. When the wires are connected, the connecting wires in the wire box are connected to the main wires on the electrical components by plugging. After the connection, the moving plate is driven by the moving column to slide in the support frame, which helps the arc-shaped clamping plate to clamp and fix the connecting wires in the wire box, so that the connecting wires and the main wires are always in a state of interconnection without external force, which can effectively prevent the connecting wires and the main wires from loosening and poor contact after long-term use.

[0020] 2. Through the cooperation between the arc block in the limit assembly and the clamp block on the main power line, before the main power line and the connecting wire in the wire box are connected to each other, the main power line needs to be bundled first, and then the connecting end of the main power line is moved into the protective shell after the bundling process, and the connecting end of the main power line is passed through the protective shell. When the main power line moves, the wire connector moves with the main power line, and the clamp block moves with the wire connector in the fixed frame. During the movement, the clamp block squeezes the arc block. After squeezing, the arc block moves under force. When the clamp block stops moving, the arc block is reset and clamped under the elastic force of the first spring, which helps to fix the wire connector of the main power line in the protective shell and avoid the movement of the wire connector of the main power line during use.

[0021] 3. The second magnetic block in the wiring harness assembly helps to restrain the main wire in the electrical box to a certain extent. Before the main wire is connected, it is first rotated by the rotating block. After the rotating block drives the first magnetic block to rotate through the threaded rod, the first magnetic block has a certain repulsive force on the second magnetic block, so that the second magnetic block slides in the fixed guide rail. After sliding, the second magnetic block and the main wire are in contact with each other. Under the action of the repulsive force, the second magnetic block and the main wire fit together, which helps to limit the movement of the main wire and keep the main wire in a neat state in the cavity in the electrical box, which is convenient for repair or maintenance when the electrical box is in failure.

[0022] 4. The lifting block in the moving assembly helps to release the restriction of the clamping assembly on the connecting wires in the wire box. When an electrical component in the cavity of the electrical box fails, the circuit in the electrical box needs to be inspected. When the circuit needs to be disassembled, the handle needs to be used to drive the lifting column to move vertically, which helps the lifting column drive the lifting block to move vertically in the support frame. When the lifting block is removed from the support frame, the lifting block and the opposite side of the two moving plates fit each other and continue to move. The lifting block can increase the gap between the two moving plates. When the gap between the moving plates increases, the arc-shaped clamping plate is separated from the connecting wires in the wire box, which helps to remove the connecting wires in the wire box for inspection and maintenance.

DETAILED DESCRIPTION

[0033] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0034] like Figures 1 to 8 As shown, an automated electrical box connection device comprises an electrical box 1, a box door 2 is hinged on the front of the electrical box 1 through a hinge seat, a wire box 101 is fixedly connected to the back of the electrical box 1, and the wire box 101 stores a certain amount of wires, a fixing plate 3 is provided in the cavity of the electrical box 1, both ends of the fixing plate 3 are fixed to the inner wall of the electrical box, three sets of electrical components 4 are installed on the fixing plate 3 at intervals, and each set of electrical components 4 is provided with protrusions 5 for limiting the electrical components 4 at the four corner ends, and the protrusions 5 are fixed to the fixing plate 3 by screws.

[0035] The front of each set of electrical components 4 is connected to a main wire 6, and the side of the wire box 101 close to the electrical box 1 passes through the electrical box 1 and is connected to multiple connecting wires. The wires in the conventional electrical box 1 are usually plugged in, which is simple and convenient, but are prone to looseness and poor contact after long-term use, resulting in a circuit break in the electrical box 1 and the electrical components 4 cannot be used normally.

[0036] Therefore, three sets of clamping assemblies are arranged in the cavity of the electrical box 1 and are located below the electrical components 4 and correspond to the electrical components 4 respectively.

[0037] The clamping assembly includes a support frame 12 whose two ends are fixed to the inner wall of the electrical box, a movable frame 13 is fixed to the upper surface of the support frame 12, and a movable groove 1301 is provided inside the movable frame 13, and two vertically upward movable plates 18 are slidably provided in the movable groove 1301, a support frame 14 is fixedly connected to the upper surface of the movable frame 13, and six circular holes 1401 are provided at intervals on the upper surface of one side of the support frame 14, and a fixed sleeve 15 is fixed to the inner side surface of both ends of the support frame 14, and a movable column 16 that slidably cooperates with the fixed sleeve 15 is fixed to the outer side surface of the movable plate 18 facing the direction of the fixed sleeve 15; a guide block 20 is fixedly connected to one side of the movable plate 18, and the upper surface of the guide block 20 is slidably connected to a limit block 21, and the limit block 21 slidably cooperates with the corresponding circular hole 1401,

[0038] It is particularly noted that: when the guide block 20 moves under force, the limit block 21 on the guide block 20 moves along with the guide block 20, and the guide block 20 and the limit block 21 are connected to each other through an elastic member, and the elastic member is an elastic sheet. When the guide block 20 moves, the limit block 21 moves under force again. Under the action of the elastic member, the limit block 21 moves out of the circular hole 1401 and then moves to another circular hole 1401.

[0039] The top of the moving plate 18 is fixedly connected with an arc-shaped clamping plate 19, and the connecting wire is located between the two arc-shaped clamping plates 19. The outer periphery of the moving column 16 is sleeved with a second spring 17, one end of the second spring 17 is connected to the fixed sleeve 15, and the other end of the second spring 17 is connected to the moving plate 18. When in use, the arc-shaped clamping plate 19 is first held by hand, and when subjected to force, the arc-shaped clamping plate 19 moves horizontally, and the moving plate 18 moves horizontally following the direction of the arc-shaped clamping plate 19, and the guide block 20 moves horizontally following the direction of the arc-shaped clamping plate 19. At this time, the distance between the two moving plates 18 increases, and then the connecting wire in the wire box 101 and the main wire 6 on the electrical component 4 are plugged into each other. After plugging, the arc-shaped clamping plate 19 is released, and the arc-shaped clamping plate 9 performs a reset movement under the elastic force of the second spring 17 on the moving column 17. After resetting, the arc-shaped clamping plate 19 and the outer part of the connecting wire in the wire box 101 fit each other.

[0040] The support frame 12 is fixed with three connecting plates 601 on the side of the inner wall of the cavity of the electrical box 1, and a limiting component is arranged on the connecting plate 601, and the limiting component includes a supporting plate 602, and the supporting plate 602 is vertically fixed on the upper surface of the connecting plate 601, and a protective shell 603 is fixed on the top of the supporting plate 602, and a fixed frame 604 is fixed on the side of the protective shell 603 away from the support frame 12, and a notch is opened inside the fixed frame 604, and a fixing rod 605 is fixed inside the notch, and a moving rod 606 is slidably connected to the side of the fixing rod 605 away from the inner wall of the notch, and the moving rod 606 is away from the fixed An arc block 607 is fixedly connected to one end of the rod 605, and a first spring 608 is sleeved on the outer circumference of the movable rod 606. One end of the first spring 608 is connected to the fixed rod 605, and the other end of the first spring 608 is connected to the arc block 607. A wire connector 609 is fixed to one end of the main wire 6 close to the protective shell 603. A circular groove is provided inside the protective shell 603, and the wire connector 609 is located inside the circular groove. A clamping block 6010 is fixed on the top of the wire connector 609. A plug is provided at the end of the connecting line away from the wire box 101, and the plug and the wire connector 609 are plugged into each other. Before use, before the main power line 6 and the connecting wires in the power line box 101 are connected to each other, the main power line 6 needs to be bundled first. After the bundling process, the connecting end of the main power line 6 is moved into the protective shell 603 and passes through the protective shell 603. When the main power line 6 moves, the wire connector 609 moves with the main power line 6, and the clamping block 6010 moves with the wire connector 609 in the fixed frame 604. During the movement, the clamping block 6010 squeezes the arc block 607. After squeezing, the arc block 607 moves under force. When the clamping block 6010 stops moving, the arc block 607 is reset and clamped under the elastic force of the first spring 608, thereby fixing the wire connector 609 of the main power line 6 in the protective shell 603 to avoid the wire connector 609 of the main power line 6 from moving during use.

[0041] A wiring harness assembly is provided on the inner walls on both sides of the electrical box 1, and the wiring harness assembly includes a fixed guide rail fixed on the side wall of the inner cavity of the electrical box, a threaded rod 9 is threadedly connected to the upper surface of the fixed guide rail 7, a rotating block 8 is fixed to the top of the threaded rod 9, and a first magnetic block 10 is fixed to the bottom of the threaded rod 9, and a second magnetic block 11 is slidably connected to the inside of the fixed guide rail 7, and the second magnetic block 11 is magnetically matched with the first magnetic block 10, and the outside of the main wire 6 is in contact with a side of the second magnetic block 11 close to the wire box 101. When in use, before the main wire 6 is connected, it is first rotated by the rotating block 8. When the rotating block 8 drives the first magnetic block 10 to rotate through the threaded rod 9, the first magnetic block 10 has a certain repulsive force on the second magnetic block 11, so that the second magnetic block 11 slides in the fixed guide rail 7. After sliding, the second magnetic block 11 contacts the main wire 6. Under the action of the repulsive force, the second magnetic block 11 and the main wire 6 fit together, which helps to limit the movement of the main wire 6 and keep the main wire 6 in a neat state in the cavity in the electrical box 1, which is convenient for repair or maintenance when the electrical box 1 is in fault.

[0042] It is particularly noted that the two sides of the first magnetic block 10 attract and repel each other with the second magnetic block 11, such as Figure 1 As shown in the figure, the first magnetic block 10 and the second magnetic block 11 repel each other. When the first magnetic block 10 rotates, the other side of the first magnetic block 10 and the second magnetic block 11 attract each other, which helps to attract the second magnetic block 11 to move, so that the second magnetic block 11 and the main wire 6 are separated from each other.

[0043] The bottom surface of the support frame 12 is provided with a moving component that cooperates with the corresponding clamping component, and the moving component includes a fixed seat 22 fixed on the bottom surface of the support frame 12, and the bottom of the fixed seat 22 is slidably connected with a lifting column 23, the lifting column 23 passes through the fixed seat 22 and is fixedly connected with a lifting block 26, the lifting block 26 passes through the support frame 12 and is located in the support frame 12, and a handle 24 is fixed to one end of the lifting column 23 away from the lifting block 26, and a third spring 25 is sleeved on the outer periphery of the lifting column 23, one end of the third spring 25 is connected to the fixed seat 22, and the other end of the third spring 25 is fixedly connected to the handle 24.

[0044] The lifting block 26 in the moving assembly helps to release the restriction of the clamping assembly on the connecting wires in the wire box 101. When the electrical component 4 in the cavity of the electrical box 1 fails, the circuit in the electrical box 101 needs to be inspected and disassembled. At this time, the lifting column 23 can be driven to move vertically by rotating the handle 24, so that the lifting column 23 drives the lifting block 26 to move vertically in the support frame 12. When the lifting block 26 is removed from the support frame 12, the lifting block 26 and the opposite side of the two moving plates 18 are fitted with each other and continue to move. The lifting block 26 can increase the gap between the two moving plates 18. When the gap between the moving plates 18 increases, the arc-shaped clamping plate 19 is separated from the connecting wires in the wire box 101, so that the connecting wires in the wire box 101 can be removed for inspection and maintenance.

[0045] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
