[0022] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] Example 1

[0024] A junction box structure includes a box body 1, at least one first inlet 2 is arranged on both sides of the upper part of the side wall of the box body 1, a condensate tank 17 is installed outside the first inlet 2, a through hole 18 corresponding to the first inlet 2 is opened on the side wall of the condensate tank 17, and a drip hole 19 is opened at the bottom of the condensate tank 17. A first inlet wire binding and fixing clamp 3 is arranged on the upper part of the box body 1, and a plurality of inlet copper bars 4 are arranged below the first inlet wire binding and fixing clamp 3, and the inlet copper bars 4 are all connected to a metering CT5, the metering CT5 is electrically connected to a circuit breaker 6, the circuit breaker 6 is connected to an outgoing copper bar 7, and the circuit breaker 6 is also electrically connected to a secondary protection element 25. At least one outlet 8 is provided at the bottom of the box body 1, and the outlet 8 is located below the outlet copper bus 7. At least one second inlet 9 is also provided at the bottom of the box body 1. An insulating protection plate 10 is provided on the outside of the circuit breaker 6. Copper busbar fastening operation holes 11 and circuit breaker operation holes 12 are provided at corresponding positions on the insulating protection plate 10. Second inlet wire binding clamps 13 are provided on both sides of the inner wall of the insulating protection plate 10. The box body 1 is axially connected to an outer door 14; a bus zero bar 15 and a ground bar 16 are also provided on the inside of the box body 1.

[0025] An inner door 20 is installed between the outer door 14 and the insulating protection plate 10. The inner door 20 is provided with a power indicator light 21, a meter 22 and an emergency stop button 23. The power indicator light 21, the meter 22 and the emergency stop button 23 are all electrically connected to the circuit breaker 6. A waterproof window 24 matching the meter 22 is provided on the outer door 14.

[0026] A drainage eave 26 is installed on the top of the box body 1. A fixed base 27 is installed at the four corners of the bottom of the box body 1. A heat dissipation hole 28 is provided on the box body 1.

[0027] Here’s how to use it:

[0028] When the upper wire is selected, the wire can be directly connected on the corresponding T-shaped copper bar. Near the first wire entry hole 2, on the top of the box body 1, a first wire entry binding clamp 3 is provided. This wire binding clamp is composed of a plurality of waist-shaped holes, which can arrange and fix the wires according to electrical rules and has a strong adjustment space.

[0029] When the lower incoming line is selected, the incoming wire should be passed through the corresponding wiring hole from bottom to top. After the wire is passed through, the relative position of the wire is designed to be just above the insulating protection plate 10 and can be in contact with the insulating protection plate 10. A second incoming wire binding clamp 13 is provided at the position of the insulating protection plate 10 to fix the incoming cable. When the wire is sent to the top of the T-shaped wiring copper bar, the wire is bent 180 degrees and then connected to the corresponding T-shaped copper bar. The wire is fixed at the bend by the binding clamp to prevent the contact position from being stressed and causing unreliable contact.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
