[0034] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0035] Example 1

[0036] This embodiment provides a distribution box, as shown in the attached figure. Figures 1-3 As shown, it includes:

[0037] The first connector 11 has one end electrically connected to the inlet board 12, which is also electrically connected to an external power supply circuit, thus providing power. The other end of the first connector 11 has a fixing part 111, and the outer wall of the fixing part 111 has an external thread 112. It should be noted that one first connector 11 corresponds to one inlet board 12, and the first connectors 11 and inlet boards 12 are configured in a one-to-one correspondence. For example, if there are three inlet boards 12, then each inlet board 12 will have one first connector 11 installed.

[0038] The second connector 13 has one end electrically connected to the wire 14. One end of the first connector 11 and the other end of the second connector 13 are each provided with a tapered portion 15, and the other end of both is provided with a tapered cavity 16 that mates with the tapered portion 15. When the other end of the first connector 11 is provided with the tapered portion 15, the other end of the second connector 13 is provided with the tapered cavity 16; conversely, when the other end of the first connector 11 is provided with the tapered cavity 16, the other end of the second connector 13 is provided with the tapered portion 15. In this embodiment, the tapered portion 15 extends into the tapered cavity 16, meaning the outer wall of the tapered portion 15 abuts against the inner wall of the tapered cavity 16.

[0039] Fastener 17 is fitted onto the connection between the tapered portion 15 and the tapered cavity 16. Fastener 17 has an internal thread 171 that mates with an external thread 112. The lower end of fastener 17 is connected and fixed to the first connector 11, while the upper end of fastener 17 creates a clamping effect, firmly fixing the tapered portion 15 and the tapered cavity 16 and improving the electrical connection between them. When the tapered portion 15 and the tapered cavity 16 mate, a positioning and fixing effect is achieved, and then the fastener 17 creates a clamping and fixing effect, improving the stability of the electrical connection.

[0040] With this structural design, under normal operating conditions, the connection between the first connector 11 and the incoming line board 12 will not affect the normal operation of the entire distribution box 18. The second connector 13 is not connected to the first connector 11 and serves as a temporary tool. When maintenance is required, the second connector 13 engages with the first connector 11, and the fastener 17 establishes an electrical connection to the conductor 14. The other end of the conductor 14 is then electrically connected to the terminal electrical equipment, providing power to the equipment (at this time, the distribution box 18 can be tripped for maintenance, while the terminal electrical equipment remains powered). After maintenance of the distribution box 18 is completed, the circuit is closed first, then the fastener 17 is released, and the second connector 13 is removed to disconnect the circuit. This structure is suitable for temporary maintenance, is simple in design, easy to connect, and highly practical; the tapered part 15 and the tapered cavity 16 create a positioning fit.

[0041] Specifically, as shown in the attached document Figures 2-3As shown, the other end of the first connector 11 is provided with a tapered portion 15. In this embodiment, the upper end of the first connector 11 is provided with the tapered portion 15, and the fixing portion 111 is located below the tapered portion 15, with the fixing portion 111 connected to the tapered portion 15. The other end of the second connector 13 is provided with a tapered cavity 16, which is located at the lower end of the second connector 13. That is, the lower end of the second connector 13 is connected and fixed to the upper end of the first connector 11, forming an electrical connection between the two. The tapered portion 15 is located on the first connector 11, which facilitates processing and also prevents dust from entering the tapered cavity 16 during long-term use, thus improving the electrical connection effect. Alternatively, the tapered cavity 16 can also be located on the first connector 11, with the two positions interchanged.

[0042] Specifically, as shown in the attached document Figures 2-3 As shown, the fastener 17 has a fastening channel 172, which is a through-type channel, meaning it has an opening at the top and a bottom. An internal thread 171 is provided on the inner wall of the fastening channel 172. The fastening channel 172 also has a tapered region 173, with the internal thread 171 located below the tapered region 173. When the fastener 17 is engaged with the first connector 11 and the second connector 13, the connection between the tapered portion 15 and the tapered cavity 16 is located in the tapered region 173. The inner wall of the tapered region 173 abuts against the outer wall of the tapered cavity 16. Through the threaded connection between the fastener 17 and the first connector 11, the inner wall of the tapered region 173 drives the side wall of the tapered cavity 16 to form a tight fit with the tapered portion 15. The inner wall of the conical region 173, the side wall of the conical cavity 16, and the conical part 15 form a tight fit, so that the side wall of the conical cavity 16 is located between the inner wall of the conical region 173 and the conical part 15. As the threaded fit between the fastener 17 and the first connector 11 becomes tighter, the fit between the three parts becomes even tighter, improving the fixing effect between the three parts and also improving the electrical connection stability between the three parts.

[0043] Specifically, as shown in the attached document Figures 2-3 As shown, the inner wall of the conical region 173 includes a first inclined surface 174 and a first plane 175. The first inclined surface 174 and the first plane 175 are connected. Here, the first plane 175 is located above the first inclined surface 174, that is, the first inclined surface 174 is located between the internal thread 171 and the first plane 175. The first plane 175 is closer to the wire 14 relative to the first inclined surface 174. The arrangement of the first plane 175 better achieves the effect of compression fixation and improves the fixation strength.

[0044] Specifically, as shown in the attached document Figures 2-3As shown, the conical portion 15 has a second inclined surface 151, and the conical cavity 16 has a third inclined surface 161. Specifically, the third inclined surface 161 refers to the fact that both the inner and outer walls of the conical cavity 16 are inclined surfaces, and the inner and outer walls are parallel to each other. The first inclined surface 174, the second inclined surface 151, and the third inclined surface 161 are parallel to each other. When the clamping clamp moves vertically downwards, the first inclined surface 174 and the first plane 175 move, creating a squeezing and fixing effect.

[0045] Specifically, as shown in the attached document Figures 2-3 As shown, the fastening channel 172 is provided with a limiting surface 176, and the top surface of the fixing part 111 is located on the movement trajectory of the limiting surface 176. The setting of the limiting surface 176 forms a limiting and fixing effect, preventing the fastener 17 from moving excessively. Here, the limiting surface 176 is located between the first inclined surface 174 and the internal thread 171.

[0046] Specifically, as shown in the attached document Figures 2-3 As shown, the outer wall of the fastener 17 has a driving surface 177. The driving surface 177 facilitates tool operation. It should be noted that, without interrupting power, insulation between the operator and the tool must be ensured. In this embodiment, the outer wall of the fastener 17 is formed as a regular hexagonal prism, meaning its cross-section is a regular hexagon.

[0047] Specifically, as shown in the attached document Figures 2-3 As shown, the first connector 11 has a bent portion 113, which connects both ends of the first connector 11. The bent portion 113 facilitates the connection with the second connector 13. In this embodiment, the inlet plate 12 is close to the inner wall of the distribution box 18. To facilitate subsequent wiring, the bent portion 113 is used to make the upper end of the first connector 11 farther away from the inner wall of the distribution box 18 relative to the lower end of the first connector 11.

[0048] Specifically, the first connector 11 is bolted to the inlet board 12. During the tightening process, the external power supply circuit is also tightened simultaneously.

[0049] Specifically, the second connector 13 and the wire 14 are riveted together. The riveting connection makes the second connector 13 and the wire 14 form a whole, which facilitates disassembly and installation. The other end of the wire 14 is used for electrical connection with the terminal electrical equipment.

[0050] Specifically, as shown in the attached document Figure 1 As shown, the distribution box 18 is provided with a wire hole 181, through which the wire 14 can be passed to the outside. The wire hole 181 can also be equipped with a protective structure, which is a closed structure when not in use.

[0051] Specifically, the incoming line plate 12 of the distribution box 18 corresponds to the incoming line terminal, and the distribution box 18 is also provided with an outgoing line terminal, which is electrically connected to the terminal power supply equipment. The distribution box 18 is also provided with a switch to control the connection or disconnection of the incoming line terminal and the outgoing line terminal, that is, the circuit control effect is achieved through the opening and closing operation of the switch.

[0052] Specifically, the first connector 11, the second connector 13, and the fastener 17 are all made of conductive materials, such as copper.

[0053] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
