[0038] Adapter 101 is used to connect the bus duct and the switch in the plug-in box.
[0039] The butt plate 103 is provided with a slot structure for the copper busbar 107 to pass through.
[0040] Four partitions 105a are provided in the transfer box 105, and the four partitions 105a separate the transfer box 105 into five transverse grooves 105b.

[0041] The conductive horizontal plate 105c is a copper busbar.
[0042] The partition plate 105a is an insulating plate, and the fixing column 105h is used to fix the conductive horizontal plate 105c in the horizontal groove 105b.
[0043] A through slot 105d is provided on one side of the transfer box 105, and the through slot 105d is correspondingly communicated with the transverse slot 105b. The conductive transverse plate 105c is connected to a power-taking bar 105e, and the power-taking bar 105e is provided through the through slot 105d.
[0044] The power strips 105e are arranged in two rows, with three strips arranged vertically in the first row and two strips arranged in the other row, which are arranged in a staggered manner. The outer cover of the power strips 105e is provided with a casing 105f.
[0045] Specifically, the vertically arranged transverse grooves 105b are numbered 1, 2, 3, 4, and 5 from top to bottom. The first column of vertical arrangement is the power-collecting bars 105e connected to the conductive transverse plates 105c at 1, 3, and 5, and the other column of vertical arrangement is the power-collecting bars 105e connected to the conductive transverse plates 105c at 2 and 4. Since the positions of the five transverse grooves 105b in the vertical direction are different, the power-collecting bars 105e at 1, 3, and 5 and the power-collecting bars 105e at 2 and 4 are staggered, and the casing 105f is used to protect and isolate the power-collecting bars 105e.
[0046] This arrangement allows the five housings 105f to be centrally arranged, with a compact structure, and is convenient for connection with the adapter 101 and the bus duct.
[0047] The casing 105f can be fixed on the transfer box 105 by gluing.
[0048] The adapter 101 includes a first panel 101a and a second panel 101b that are spliced together. The first panel 101a is provided with a first pipe head 101c, and the second panel 101b is provided with a second pipe head 101d. The first pipe head 101c and the second pipe head 101d are correspondingly connected to form a pipe groove 101e.
[0049] It should be noted that five first tube heads 101c are provided on the first puzzle plate 101a, and five second tube heads 101d are provided on the second puzzle plate 101b. The five second tube heads 101d correspond to the positions of the five sleeves 105f, and the second tube heads 101d are embedded in the sleeves 105f.
[0050] A fixing groove 101f is arranged in the tube groove 101e, and a conductive member 108 is arranged in the fixing groove 101f. The conductive member 108 includes a vertical plate 108a embedded in the fixing groove 101f and clamps 108b arranged at both ends of the vertical plate 108a.
[0051] The clamp 108b includes a first bent edge strip 108c and a second bent edge strip 108d. The second pipe head 101d is embedded in the casing 105f. The power strip 105e is clamped by the first bent edge strip 108c and the second bent edge strip 108d.
[0052] The first bent side strip 108c and the second bent side strip 108d are symmetrically arranged, and the bending structure makes both of them have a certain elasticity. The power supply bar 105e is inserted between the first bent side strip 108c and the second bent side strip 108d to push the latter two to both sides, so as to keep the first bent side strip 108c and the second bent side strip 108d tightly connected with the power supply bar 105e.
[0053] A connecting plate 109 is disposed on the outer side of the back side of the box body 100 . The connecting plate 109 is fixed on the box body 100 . A hole structure is disposed on the connecting plate 109 , and the adapter 101 is correspondingly disposed in the hole structure.
[0054] The ends of the first bent edge strip 108c and the second bent edge strip 108d are expanded with guide plates 108e, which are used for guiding so that the power strip 105e can be inserted between the first bent edge strip 108c and the second bent edge strip 108d when it is not in the center of the casing 105f.
[0055] A first slide groove 106a, a second slide groove 106b and a third slide groove 106c are provided on the other side of the transfer box 105. A first isolation bar 106d is provided between the first slide groove 106a and the second slide groove 106b, and a second isolation bar 106e is provided between the second slide groove 106b and the third slide groove 106c. The second isolation bar 106e is higher than the first isolation bar 106d.
[0056] The copper bar 107 includes a first copper bar 107a, a second copper bar 107b and a third copper bar 107c. The first copper bar 107a, the second copper bar 107b and the third copper bar 107c are staggered. The first isolation bar 106d is arranged between the first copper bar 107a and the second copper bar 107b, and the second isolation bar 106e is arranged between the second copper bar 107b and the third copper bar 107c.
[0057] The first copper bar 107a, the second copper bar 107b and the third copper bar 107c are respectively connected to the switch with three-phase electricity.
[0058] The first isolation strip 106d and the second isolation strip 106e are insulating strip structures.
[0059] A first sliding block is disposed in the first sliding groove 106a. The first sliding block is fixedly connected to the first copper bar 107a. The first sliding block is in contact with the conductive horizontal plate 105c.
[0060] The first sliding block is crimped and connected to the first copper bar 107a by bolts.
[0061] The first slider is connected to the conductive transverse plate 105c in the second transverse groove 105b by sliding contact, the second slider is arranged in the second slide groove 106b, the second slider is connected to the second copper bar 107b by bolt crimping, the second slider is connected to the conductive transverse plate 105c in the third transverse groove 105b by sliding contact, the third slider is arranged in the third slide groove 106c, the third slider is connected to the third copper bar 107c by bolt crimping, and the third slider is connected to the conductive transverse plate 105c in the fourth transverse groove 105b by sliding contact.
[0062] A guide rail is provided on the strap 103, and the switch is provided on the guide rail. The switch can slide on the guide rail. The above structure enables the switch to slide on the guide rail. Similarly, the first slider, the second slider and the third slider can slide synchronously in the corresponding slide grooves, and due to the setting of the first isolation bar 106d and the second isolation bar 106e, the first copper bar 107a, the second copper bar 107b and the third copper bar 107c are isolated from each other during the movement and will not contact each other, thereby avoiding the risk of short circuit.
[0063] Furthermore, the switch 106 is provided with a slot 109a and a conductive slot 109b, the end of the first copper strip 107a is embedded in the slot 109a, a conductive plate 109c is provided in the conductive slot 109b, a return spring 109d is provided on the conductive plate 109c, and a crimping bolt 109e is also provided through the switch 106.
[0064] Since the connection structure of the first copper bar 107a is tight and difficult to remove, the copper busbar structure is used to ensure the firm connection of the electrical structure. However, there are always situations where power needs to be turned off for inspection and maintenance. Therefore, the above structure is set up so that when in use, the crimping bolt 109e is used to squeeze the conductive plate 109c so that the conductive plate 109c contacts the first copper bar 107a to draw electricity. During inspection, the crimping bolt 109e is loosened, and the conductive plate 109c returns to its original position under the action of the return spring 109d. The conductive plate 109c is disconnected from the first copper bar 107a, and the switch loses power.
[0065] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.
[0066] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
