[0002] New energy electrical cabinet is a kind of equipment specially used for power distribution and control in the field of new energy. Electrical components are arranged in the electrical cabinet, and the electrical components are electrically connected to external cables, and the external cables pass through the housing to connect to external equipment / lines.

[0003] The external cable structure commonly used in the related art includes an outermost plastic-coated metal hose, an embedded tube arranged in the plastic-coated metal hose, and an innermost wire core structure, wherein the plastic-coated metal hose is usually a spiral corrugated tube structure.

[0004] The existing plastic-coated metal hose is directly passed through the through hole on the electrical cabinet housing, and certain waterproof measures need to be taken at the through hole. However, since the outer layer of the plastic-coated metal hose is a corrugated tube, it is difficult to form a complete sealing structure between the outer circumference of the corrugated tube and the inner wall of the through hole on the electrical cabinet housing. In rainy weather, rainwater can easily enter the electrical cabinet housing from the outside. Summary of the invention

[0007] By adopting the above technical solution, the cable connector is installed on the electrical cabinet. When the cable is passed through the cable connector, the bellows is sleeved outside the installation tube, so that the bellows remains in the hose cup and the embedded tube extends to the other side of the cable connector, thereby realizing separation of the embedded tube from the bellows; a sealing structure is formed between the second joint structure and the embedded tube to prevent water vapor from entering the electrical cabinet housing from the outside, thereby improving the sealing connection effect between the cable and the electrical cabinet; in the process of installing the compression nut on the first inner tube, the limit ring pushes the first clamping ring to contact the outer edge, thereby pressing the outer edge, so that when the bellows is installed on the installation tube, the inner cup of the hose is not easy to move.

[0008] Optionally, a threaded edge is provided on the outer circumferential surface of the mounting tube, and the threaded edge can cooperate with the threaded groove inside the corrugated tube.

[0009] By adopting the above technical solution, the bellows is threaded onto the outside of the mounting tube so that the thread edge is located in the thread groove inside the bellows, thereby preventing the bellows rod from directly detaching from the mounting tube along the axial direction of the mounting tube.

[0013] By adopting the above technical solution, when the second joint structure is connected to the first joint structure, the second internal tube is threadedly connected to the first external tube until the second clamping ring is tightly pressed against the first chamfered surface. As the second internal tube continues to move toward the first external tube, the second clamping ring is deformed toward its axial direction. The second clamping ring drives the sealing ring to press against the embedded tube of the hose, making the embedded tube difficult to move. At the same time, a sealing structure is formed between the second joint structure and the embedded tube to prevent water vapor from passing through the cable connector.

[0014] Optionally, the outer circumferential surface of the sealing ring is provided with a positioning ring block located between the second clamping ring and the bottom wall of the positioning groove.

[0031] Reference Figure 1 and Figure 2The first inner tube 12 is fixedly connected to the end surface of the first joint body 11. The clamping nut 14 is threadedly connected to the first inner tube 12, and the inner circumferential surface of the clamping nut 14 is fixedly connected to a limiting ring 141, which is located on the side of the first inner tube 12 away from the first joint body 11.

[0032] Reference Figure 2 , the hose inner cup 15 can be inserted into the first inner tube 12. The hose inner cup 15 includes a mounting tube 151, a bent portion 152, an outer edge 153 and a threaded edge 154.

[0033] Reference Figure 2 and Figure 3 , the bent portion 152 can be inserted into the first internal pipe 12. The outer edge 153 is fixedly connected to one end of the bent portion 152. When the outer edge 153 is pressed against the first internal pipe 12, the inner cup 15 of the hose is restricted from being further inserted into the first internal pipe 12.

[0034] According to Figure 2 and Figure 3 The mounting tube 151 is located inside the outer edge 153 , and the mounting tube 151 is fixedly connected to a side of the bending portion 152 away from the outer edge 153 .

[0035] Reference Figure 2 and Figure 3 , a threaded edge 154 is provided on the outer circumferential surface of the mounting tube 151, and the end surface of the mounting tube 151 away from the bending portion 152 is fitted with the surface of the threaded edge 154 away from the bending portion 152. The threaded edge 154 can cooperate with the thread groove on the inner wall of the corrugated tube. A notch is provided on the end surface of the mounting tube 151 away from the bending portion 152, so that the corrugated tube can be more easily screwed onto the outside of the mounting tube 151. Furthermore, the distance between the threaded edge 154 and the outer surface of the mounting tube 151 gradually increases as it approaches the bending portion 152.

[0036] Reference Figure 2 and Figure 3, the first clamping ring 16 is located between the limiting ring 141 and the outer edge 153. The first clamping ring 16 is made of plastic. When the clamping nut 14 is connected to the first inner tube 12, the outer edge 153 is pressed against the first inner tube 12, the first clamping ring 16 is pressed against the side of the outer edge 153 away from the first inner tube 12, and the limiting ring 141 is pressed against the side of the first clamping ring 16 away from the first inner tube 12.

Second, the embedded tube is passed through the first joint structure 1, the second joint structure 2 and the third joint structure 3 in sequence, and the corrugated tube is rotated to the outside of the mounting tube 151, so that the thread edge 154 is in the thread groove inside the corrugated tube.

[0053] In the third step, the first external tube 13 and the second internal tube 22 are tightened, so that the second clamping ring 24 is pressed against the inclined surface of the first chamfer 111. As the first external tube 13 and the second internal tube 22 are further tightened, the second clamping ring 24 is deformed toward the center, and the second clamping ring 24 drives the sealing ring 25 to deform, so that the sealing ring 25 is pressed against the embedded tube, sealed and pre-fixed. In the fourth step, the two arc blocks 361 are clamped against the embedded tube by tightening the operating bolts 363.

In other embodiments, the number of the through holes 1511 may be four, six, or other numbers.

[0055] Reference Figure 6 and Figure 7 The hose inner cup 15 is provided with an adjustment inner cup 17. The adjustment inner cup 17 includes a first operation tube 171, an operation portion 172, a second operation tube 173 and an operation strip 174.

The first operating tube 171, the operating portion 172, and the second operating tube 173 enclose an operating cavity.

When the operating strip 174 does not drive the mounting tube 151 to deform, a gap is left between the operating ring 176 and the outer edge 153.

[0060] The implementation principle of Example 2 is: after the bellows is installed on the mounting tube 151, continue to drive the clamping nut 14 and the first inner tube 12 to tighten, so that the limiting ring 141 pushes the first clamping ring 16, and the first clamping ring 16 pushes the operating ring 176, that is, drives the adjustment inner cup 17 to move, so that the operating strip 174 drives the mounting tube 151 to deform, so that the thread edge 154 is more tightly pressed against the bellows.
