Figures 1-3In this embodiment, the terminal structure includes a terminal base 1, a long copper busbar 2, a first limiting and clamping device, a first locking device, a first wiring guide sleeve 3, a connecting clip, a terminal frame 4, a short copper busbar 5, a second limiting and clamping device, a second locking device, and a second wiring guide sleeve 6. The terminal base 1 is installed at the bottom inner part of the housing 7, and two mounting slots 11 are formed on the terminal base 1, which are sequentially connected. Two long copper busbars 2 are provided, each positioned in one of the two mounting slots 11. Multiple first limiting and clamping devices are provided, positioned between the two long copper busbars 2 and the two mounting slots 11, respectively. By providing these first limiting and clamping devices, the long copper busbars 2 can be securely and firmly fixed in the mounting slots 11.
[0023] Specifically, refer to Figures 1-3 In this embodiment, the limiting and clamping device includes a limiting base 8, a limiting intermediate seat 81, and limiting protrusions 82. Two limiting bases 8 are provided, symmetrically installed at the bottom of both ends of the mounting groove 11. The limiting intermediate seat 81 is installed at the bottom of the middle section of the mounting groove 11, and the long copper busbar 2 is placed on the two limiting bases 8 and the limiting intermediate seat 81, so that the two limiting bases 8 and the limiting intermediate seat 81 simultaneously provide effective support for the long copper busbar 2. Several limiting protrusions 82 are provided, respectively installed on the surrounding walls of the mounting groove 11, and these limiting protrusions 82 abut against the side walls of the long copper busbar 2 to securely limit the long copper busbar 2 in the mounting groove 11.
[0024] At the same time, refer to Figures 2-4 In this embodiment, four wiring guide sleeves 3 are provided, and the four wiring guide sleeves 3 are evenly divided into two groups. Each group of wiring guide sleeves 3 is securely installed between the two ends of the long copper busbar 2 and the two ends of the mounting groove 11 by a locking device. The wiring guide sleeves 3 cooperate with the outer side of the cable. By setting the structure of the wiring guide sleeves 3 and the locking device cooperating with each other, the ground wire and the neutral wire can be guided and neatly connected.
[0025] Specifically, in this embodiment, the locking device includes a locking nut 9, a terminal block 92, and a locking screw 93. Each of the limiting bases 8 has a limiting groove 83. Several locking nuts 9 are provided, each engaging with one of the limiting grooves 83 to securely lock and limit the locking nut 9 around its perimeter.
[0026] Meanwhile, bolt holes 91 are provided at both ends of the long copper busbars 2, and a terminal block 92 is installed on one side of the wiring guide sleeve 3. The terminal block 92 has bolt holes 94. When the wiring guide sleeve 3 abuts against the long copper busbar 2 through the terminal block 92, the bolt holes 91 and 94 correspond to each other. Several locking screws 93 are provided, and the locking screws 93 pass through both bolt holes 91 and 94, and are threadedly connected to the locking nut 9. In this way, by using the locking screws 93 to pass through bolt holes 94 and 91 in sequence and screw them into the locking nut 9, the wiring guide sleeve 3 and the long copper busbar 2 can be firmly connected together, so as to lock and connect the cables neatly and orderly.
[0027] Additionally, refer to Figure 2 and Figure 5 In this embodiment, the connector 4 is mounted on the connector base 1 via a connecting clip, and the bottom of the connector 4 simultaneously engages with the tops of the two long copper busbars 2. The connecting clip facilitates the interlocking of the connector 4 and the connector base 1. Furthermore, several abutment plates 41 are installed at the bottom of the connector 4. When the connector 4 is engaged with the connector base 1, these abutment plates 41 abut against the tops of the two long copper busbars 2 respectively, thereby clamping and limiting the long copper busbars 2.
[0028] Specifically, referring to Figure 2 , Figure 3 as well as Figure 5 In this embodiment, the connecting clip is a connecting plate 42 installed at the bottom center of the connector 4, with the clamping plates 41 symmetrically located on both sides of the connecting plate 42. A base groove 12 is provided in the middle of the connector base 1, and this base groove 12 cooperates with the bottom end of the connecting plate 42, allowing the connecting plate 42 to be inserted into the base groove 12. Simultaneously, base latches 13 are provided on both ends of the base groove 12, and connecting latches 43 are symmetrically provided on the bottom of the connecting plate 42. These connecting latches 43 and base latches 13 interlock, thereby allowing the connector 4 to be latched into the interior of the base groove 12 via the connecting plate 42, thus achieving a latching connection between the connector 4 and the connector base 1.
[0029] Furthermore, in this embodiment, three mounting cavities 44 are provided on the terminal block 4, and the short copper busbar 5 is disposed on one of the mounting cavities 44; and the limiting clamping device 2 is disposed between the short copper busbar 5 and the mounting slots 11. By providing the limiting clamping device 2, the short copper busbar 5 can be securely fixed and installed on the mounting cavity 44.
[0030] Reference Figure 2 and Figure 5In this embodiment, the structure of the second limiting clamping device is similar to that of the first limiting clamping device; specifically, the second limiting clamping device includes a limiting base 8, a limiting intermediate seat 81, and a limiting protrusion 82. There are six limiting bases 8, which are evenly divided into three groups, with each group of limiting bases 8 installed at the bottom inner part of the mounting cavity 44. There are three limiting intermediate seats 81, which are located at the center of the three mounting cavities 44, and are installed between two limiting bases 8.
[0031] This allows the short copper busbar 5 to be placed on the two limiting bases 8 and the limiting intermediate seat 81, so that the two limiting bases 8 and the limiting intermediate seat 81 can effectively support the short copper busbar 5. Several limiting protrusions 82 are provided, and these limiting protrusions 82 are respectively installed on the inner bottom of both sides of the mounting cavity 44 and the top of both sides of the limiting intermediate seat 81. These limiting protrusions 82 abut against the side wall of the short copper busbar 5, so as to securely limit the short copper busbar 5 on the mounting cavity 44.
[0032] Meanwhile, the second limiting and clamping device also includes a clamping mechanism, which is located between the terminal frame 4 and the housing 7, and clamps together with the short copper busbar 5 to further securely clamp the short copper busbar 5 onto the terminal frame 4. Specifically, refer to... Figure 2 and Figure 5 In this embodiment, the locking mechanism includes a first locking plate 45, a second locking plate 71, and a third locking plate 72.
[0033] Two fixing plates 45 are provided, and the two fixing plates 45 are symmetrically installed on the top of the wiring bracket 4; the fixing horizontal plate 71 is installed on the inner top of the box body 7; two fixing plates 72 are provided, and the two fixing plates 72 are symmetrically installed on the bottom of the fixing horizontal plate 71, and fixing slots 721 are symmetrically opened at the bottom end of the two fixing plates 72. These fixing slots 721 respectively engage with the two fixing plates 45, so that the two fixing plates 72 are respectively engaged with the two fixing plates 45, thereby realizing the stable clamping of the short copper busbar 5.
[0034] Secondly, refer to Figure 2 , Figure 5 as well as Figure 6 In this embodiment, two wiring guide sleeves 6 are provided. Both wiring guide sleeves 6 are securely installed between the two ends of the short copper busbar 5 and the two ends of the mounting cavity 44 by locking device 2. The wiring guide sleeves 6 cooperate with the outer side of the cable. By setting the wiring guide sleeves 6 and locking device 2 to cooperate with each other, the live wire cable can be guided and installed and neatly wired.
[0035] In this embodiment, the structure of the second locking device is the same as that of the first locking device; specifically, the second locking device includes a locking nut 9, a terminal block 92, and a locking screw 93. Each of the limiting bases 8 has a limiting groove 83. Two locking nuts 9 are provided, each engaging with one of the two limiting grooves 83, thus securing the locking nut 9 securely within the limiting groove 83.
[0036] Meanwhile, bolt holes 91 are provided at both ends of the short copper busbars 5, and a terminal block 92 is installed on one side of the wiring guide sleeve 6. The terminal block 92 has bolt holes 94. When the wiring guide sleeve 6 abuts against the short copper busbars 5 through the terminal block 92, the bolt holes 91 and 94 correspond to each other. Two locking screws 93 are provided, which pass through both bolt holes 91 and 94 and are threadedly connected to the locking nut 9. In this way, by using the locking screws 93 to pass through bolt holes 94 and 91 in sequence and screw them into the locking nut 9, the wiring guide sleeve 6 and the short copper busbars 5 can be firmly connected together, so as to lock and connect the cables neatly and orderly.
[0037] Preferably, in this embodiment, a locking disc 95 is installed on each of the aforementioned locking screws 93. The locking disc 95 increases the force-bearing area between the locking screw 93 and the terminal block 92, thereby making the locking screw 93 more securely fix the terminal block 92 to the long copper busbar 2 or the short copper busbar 5. Furthermore, openings 84 are provided on both sides of the limiting grooves 83. By designing these two openings 84 on the limiting grooves 83, it is convenient for operators to remove the locking nut 9 from the limiting grooves 83 using tools.
[0038] Meanwhile, each of the limiting grooves 83 has a relief groove 85 at its bottom. The relief groove 85 cooperates with the bottom end of the screw of the locking screw 93, so that the locking screw 93 is screwed into the locking nut 9. The bottom end of the screw of the locking screw 93 can extend into the relief groove 85, thereby making the locking between the locking screw 93 and the locking nut 9 more secure, which can further improve the stable connection between the terminal block 92 and the long copper busbar 2 or the short copper busbar 5.
[0039] Additionally, refer to Figure 1 and Figure 2In this embodiment, the box body 7 includes a base frame 73 and a top frame 74. A clamping assembly is provided between the base frame 73 and the top frame 74. The clamping assembly includes a clamping top tube 741 and a clamping base 731. There are four clamping top tubes 741, which are evenly installed at the four corners of the top of the top of the top frame 74. Both ends of the fixing cross plate 71 and both sides of the two fixing clamping plates 72 are installed on the top frame 74.
[0040] Meanwhile, four clamping bases 731 are provided, evenly installed at the four corners of the bottom inner end of the base frame 73. Each clamping base 731 has a clamping bottom hole 732, which engages with the clamping top tube 741, allowing the top frame 74 to be inserted into the clamping bases 731 on the base frame 73 through the clamping top tube 741, thereby clamping the base frame 73 and the top frame 74 together. Additionally, the wiring base 1 is installed at the bottom inner end of the base frame 73.
[0041] And refer to Figure 2 and Figure 3 In this embodiment, a cable management base frame 733 is also installed on the inner bottom side of one end of the base frame 73. A cable management top frame 734 is installed on the cable management base frame 733 by means of a disassembly and assembly component, which consists of two disassembly and assembly bolts. The cable management top frame 734 is securely installed on the cable management base frame 733 by means of the two disassembly and assembly bolts. Then, through the cooperation between the cable management top frame 734 and the cable management base frame 733, the three cables, namely the live wire, the neutral wire and the ground wire, can be neatly arranged and installed, thereby preventing the cables from being installed in a messy manner.
[0042] Meanwhile, a cover plate 75 is bolted to the top of the top frame 74. The cover plate 75 is designed to cover the top of the box 7 to protect the cables or components inside the box 7. When the cover plate 75 is removed, the cables and components can be neatly installed or easily disassembled.
[0043] Therefore, the solution of this application, through the structure of the wiring base 1, mounting groove 11, long copper busbar 2, limit clamping device 1, locking device 1, wiring guide sleeve 1 3, connecting clip, wiring bracket 4, mounting cavity 44, short copper busbar 5, limit clamping device 2, locking device 2, and wiring guide sleeve 2 6 working together, can conveniently arrange and store cables neatly in the box 7, so that the wiring of cables is not only neat and orderly, but also clearer, more efficient and safer, thereby avoiding the problem of electrical safety caused by messy wiring.
