[0023] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0024] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] like Figure 1-2 As shown, a busbar plug-in box with visual connection in this embodiment includes a box body 1 and a plug-in assembly 2. A mounting groove is provided on the back of the box body 1. The plug-in assembly 2 is fixedly mounted in the mounting groove on the back of the box body 1. The plug-in assembly 2 passes through the box body 1.

[0026] The plug assembly 2 includes a plug block 21, a plurality of holes 22 are formed on the top of the plug block 21, the holes 22 penetrate the plug block 21, a conductive frame 23 is fixedly connected inside the holes 22, springs 24 are fixedly connected to the inner walls of both sides of the conductive frame 23, and a clamping plate 25 is fixedly connected to one end of the spring 24. Figure 2As shown, there is a gap between two adjacent clamps 25, and the bottom of the plug-in block 21 can be seen from the top of the plug-in block 21 through the gap between the two clamps 25 in the hole groove 22, so as to facilitate the plugging with the plug on the bus duct. The bottom of the clamp 25 is fixedly connected with an inclined plate 26, and the inclined plate 26 can play a guiding role, so that the plug on the bus duct can be smoothly inserted between the two clamps 25. Support plates 29 are fixedly connected on both sides of the top of the hole groove 22, and the bottom of the support plate 29 is in conflict with the top of the clamp 25. When the plug of the bus duct is inserted between the two clamps 25, the support plate 29 supports the top of the clamp 25 to avoid the clamp 25 moving upward during the insertion of the plug, resulting in the problem of bending and damage of the spring 24.

[0027] Specifically, the circuit breaker 11 is fixedly installed inside the box 1, a groove 27 is opened at the top of the plug-in block 21 corresponding to the conductive frame 23, a conductive plate 28 is fixedly connected to the side of the conductive frame 23 corresponding to the groove 27, and the pad 28 is located in the groove 27. The conductive plate 28 can be connected to the terminal of the circuit breaker 11 through wires, thereby achieving the purpose of power transmission.

[0028] Specifically, a box cover 12 is hinged on the front side of the box body 1 , and a wire threading groove 13 is provided at the bottom of the box body 1 .

[0029] Example 1: Figure 3-4 As shown, a U-shaped frame 3 is fixedly installed on the top of the plug-in block 21, and a protective plate 31 is fixedly connected to the top of the U-shaped frame 3. The protective plate 31 can shield the conductive plate 28 to avoid the problem of accidentally touching the conductive plate 28 and causing electric shock when operating the circuit breaker 11.

[0030] Example 2: Figure 2-3 As shown, positioning blocks 32 are fixedly connected to both sides of the U-shaped frame 3, and magnetic blocks 34 are fixedly connected to both sides of the plug-in block 32. The magnetic blocks 34 are magnetically connected to the positioning blocks 32 for easy disassembly and assembly.

[0031] Preferably, a positioning column 33 is fixedly connected to the bottom of the positioning block 32, a positioning hole 35 is opened on the top of the magnetic block 34, and the positioning column 33 is inserted into the positioning hole 35 to position the magnetic block 34 and the positioning block 32 to avoid the problem of the U-shaped frame 3 sliding off.

[0032] Furthermore, a chamfer is provided at the bottom of the positioning post 33 to facilitate the insertion of the positioning post 33 into the magnetic block 34 .

[0033] The working principle of the utility model is as follows: when in use, when the plug-in assembly 2 is connected to the plug of the bus duct, the bottom of the plug-in block 21 can be seen through the gap between the two adjacent support plates 29, so as to judge whether the plug of the bus duct corresponds to the hole slot 22. If not, the position of the box body 1 can be appropriately adjusted. When the plug of the bus duct corresponds to the hole slot 22, the box body 1 is pressed downward to insert the plug of the bus duct between the two clamping plates 25.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] 1. When the plug-in assembly 2 is connected to the plug of the bus duct, the bottom of the plug-in block 21 can be seen through the gap between the two clamping plates 25 in the hole slot 22, so that it can be observed whether the plug of the bus duct corresponds to the hole slot 22, and there is no need to observe from the side of the box body 1, thereby facilitating the connection between the plug-in assembly 2 and the bus duct plug, thereby facilitating the installation of the bus plug-in box.

[0036] 2. By providing a U-shaped frame 3 and a protective plate 31 and installing them on the plug-in assembly 2, the conductive plate 28 can be shielded, thereby shielding the conductive assembly. When operating the circuit breaker 11, the problem of electric shock caused by accidentally touching the conductive plate 28 can be avoided, thereby improving safety.

[0037] 3. The U-shaped frame 3 is magnetically connected and fixed to the plug-in block 21 through the magnetic block 34 and the positioning block 32. Therefore, the U-shaped frame 3 and the protective plate 31 are very easy to disassemble and assemble. In addition, the U-shaped frame 3 can be positioned in conjunction with the positioning column 33 and the positioning hole 35 to prevent the U-shaped frame 3 from slipping. While ensuring that the U-shaped frame 3 and the protective plate 31 are easy to disassemble and assemble, the stability of the installation of the U-shaped frame 3 and the protective plate 31 is also ensured.

[0038] 4. The bottom of the support plate 29 contacts the top of the clamping plate 25. When the plug of the bus duct is inserted between the two clamping plates 25, the support plate 29 supports the top of the clamping plate 25 to prevent the clamping plate 25 from moving upward during the plug insertion process, causing the spring 24 to bend and be damaged, thereby achieving the purpose of protecting the spring 24.
