Description

Technical Field

[0001] This application relates to the technical field of cable connectors, and particularly to a cable connector applied to a new energy electrical cabinet. Background Art

[0002] A new energy electrical cabinet is a device specifically used for power distribution and control in the new energy field. Electrical components are arranged inside the electrical cabinet, and the electrical components are electrically connected to external cables. The external cables pass through the housing and are connected to external devices / lines.

[0003] In related technologies, the commonly used external cable structure usually includes an outer plastic-coated metal hose, an inner tube arranged inside the plastic-coated metal hose, and an inner core structure at the innermost layer. The plastic-coated metal hose is usually a spiral corrugated pipe structure.

[0004] In the existing technology, the plastic-coated metal hose is directly passed through a through hole on the housing of the electrical cabinet, 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 pipe, it is difficult to form a complete sealing structure between the outer circumferential surface of the corrugated pipe and the inner wall of the through hole on the housing of the electrical cabinet. In rainy weather, rainwater is likely to enter the electrical cabinet housing from the outside. Summary of the Invention

[0005] In order to improve the sealing connection effect between the cable and the electrical cabinet, this application provides a cable connector applied to a new energy electrical cabinet.

[0006] A cable connector applied to a new energy electrical cabinet provided by this application adopts the following technical solutions:

[0007] A cable connector applied to a new energy electrical cabinet includes a first joint structure capable of being connected to a corrugated pipe. A second joint structure capable of forming a sealing structure with an inner tube is arranged on one side of the first joint structure. The first joint structure includes a first joint body. One end of the first joint body is provided with a first inner connecting pipe. The first inner connecting pipe is externally threaded and connected with a compression nut. A limiting ring is arranged on the inner circumferential surface of the compression nut. A hose inner cup is inserted into the first inner connecting pipe. The hose inner cup includes a bent portion capable of being inserted into the first inner connecting pipe. One end of the bent portion is connected with an outer edge located between the limiting ring and the first inner connecting pipe. The other end of the bent portion is connected with an installation pipe capable of being inserted into the corrugated pipe. The installation pipe is located inside the outer edge. A first clamping ring located between the outer edge and the limiting ring is arranged inside the compression nut.

[0008] By adopting the above technical solution, when the cable connector is installed on the electrical cabinet and the cable is passed through the cable connector, the corrugated pipe is sleeved outside the installation pipe, so that the corrugated pipe remains in the hose cup body, while the embedded pipe extends to the other side of the cable connector, realizing the separation of the embedded pipe and the corrugated pipe; a sealing structure is formed between the second joint structure and the embedded pipe to prevent water vapor from entering the electrical cabinet housing from the outside, improving the sealing connection effect between the cable and the electrical cabinet; during the installation of the compression nut on the first inner connecting pipe, the limiting ring pushes the first clamping ring to contact the outer edge, thereby pressing the outer edge tightly, so that when the corrugated pipe is installed on the installation pipe, the inner cup of the hose is not easy to move.

[0009] Optionally, a threaded edge is provided on the outer circumferential surface of the installation pipe, and the threaded edge can cooperate with the threaded groove inside the corrugated pipe.

[0010] By adopting the above technical solution, the corrugated pipe is threaded outside the installation pipe, and the threaded edge is located in the threaded groove inside the corrugated pipe, preventing the corrugated rod from directly detaching from the installation pipe along the axial direction of the installation pipe.

[0011] Optionally, the first clamping ring is elastic. When the first clamping ring deforms and squeezes the corrugated pipe, the first inner connecting pipe and the compression nut are in a locked state.

[0012] By adopting the above technical solution, when the first inner connecting pipe is connected to the compression nut, the first clamping ring deforms, and the first clamping ring generates an axial reaction force, which has an anti-loosening effect on the connection between the first inner connecting pipe and the compression nut; in addition, the first clamping ring deforms in the direction of its axis, so that the first clamping ring abuts against the corrugated pipe, and the first clamping ring and the installation pipe cooperate to fix the corrugated pipe.

[0013] Optionally, a first outer connecting pipe is provided on the side of the first joint body away from the first inner connecting pipe. A first chamfer is provided on the first joint body. The first chamfer is provided at the junction of the end face of the first joint body facing the first outer connecting pipe and the inner circumferential surface of the first joint body. The second joint structure includes a second joint body. A second inner connecting pipe that can be threadedly connected inside the first outer connecting pipe is provided on the side of the second joint body facing the first joint body. A positioning groove is provided on the end face of the second joint body facing the second inner connecting pipe. A second clamping ring located inside the second inner connecting pipe is inserted in the positioning groove. The first chamfer slope is on the moving path of the second clamping ring. A communication hole is provided on the outer circumferential surface of the second clamping ring, and the communication hole penetrates the second clamping ring toward the end face away from the second joint body. An elastic sealing ring is provided inside the second clamping ring, and the second clamping ring and the sealing ring extend outside the second inner connecting pipe.

[0014] By adopting the above technical solution, when connecting the second joint structure to the first joint structure, thread the second inner connecting pipe into the first outer connecting pipe until the second clamping ring abuts against the first chamfered inclined surface. As the second inner connecting pipe continues to move towards the first outer connecting pipe, the second clamping ring deforms in the direction of its axis, and the second clamping ring drives the sealing ring to abut against the inner embedded pipe of the hose, making it difficult for the inner embedded pipe to move. At the same time, a sealing structure is formed between the second joint structure and the inner embedded pipe to prevent water vapor from passing through the cable connector.

[0015] Optionally, a positioning ring block is provided on the outer circumferential surface of the sealing ring and is located between the second clamping ring and the bottom wall of the positioning groove.

[0016] By adopting the above technical solution, when the second clamping ring squeezes the sealing ring and deforms it, the position of the sealing ring is not easily deviated.

[0017] Optionally, a plurality of the second joint structures are provided, and the second inner connecting pipe can be threadedly connected to the adjacent second outer connecting pipe.

[0018] By adopting the above technical solution, a plurality of second joint structures are provided to further improve the waterproof performance of the joint; when the waterproof structure of one second joint structure fails, the other second joint structures can still achieve the waterproof function.

[0019] Optionally, a third joint structure that can be installed on the electrical cabinet housing is provided on the side of the second joint structure away from the first joint structure. The third joint structure includes a third joint body, and a fourth inner connecting pipe is provided on one side of the third joint body. An outer thread of the fourth inner connecting pipe is threadedly connected with a locking nut.

[0020] By adopting the above technical solution, pass the fourth inner connecting pipe through the electrical cabinet housing, and then thread the locking nut onto the fourth inner connecting pipe until the end faces of the third joint body and the locking nut that are close to each other both abut against the electrical cabinet housing, so as to fix the third joint structure to the electrical cabinet housing.

[0021] Optionally, a clamping assembly is provided on the locking nut. The clamping assembly includes two arc-shaped blocks provided on the side of the locking nut away from the third joint body. The two arc-shaped blocks are symmetric with each other. Two operating plates are provided between the two arc-shaped blocks. The operating plates are connected to the end face of the locking nut away from the third joint body. Operating bolts connecting the three are provided between the operating plates and the two arc-shaped blocks.

[0022] By adopting the above technical solution, pass the inner embedded pipe of the hose through between the two arc-shaped blocks, place the arc-shaped blocks on both sides of the inner embedded pipe, the rod part of the operating bolt passes through the arc-shaped block and the operating plate and is threadedly connected to the other arc-shaped block, so that the two arc-shaped blocks clamp the inner embedded pipe of the hose.

[0023] Optionally, an adjusting inner cup is sleeved outside the inner cup of the hose. A plurality of through holes are formed in the outer circumferential surface of the mounting pipe. Eight through holes penetrate the mounting pipe in a direction away from the bent portion. The adjusting inner cup includes a first operating pipe sleeved outside the bent portion and a second operating pipe located inside the mounting pipe. An operating portion connecting the two is arranged between the first operating pipe and the second operating pipe. An operating strip capable of driving the mounting pipe to deform is arranged on the outer circumferential surface of the second operating pipe. An operating ring is arranged on one side of the outer edge away from the first operating pipe. An operating block is fixedly connected to the end surface of the operating ring facing the outer edge. A jack through which the operating block can pass is formed in the outer edge. One side of the operating block away from the operating ring is connected to the first operating pipe; when the operating strip does not drive the mounting pipe to deform, a gap is left between the operating ring and the outer edge.

[0024] By adopting the above technical solution, after the corrugated pipe is installed on the mounting pipe, continue to drive the compression nut to move towards the first inner connecting pipe, so that the limiting ring pushes the first clamping ring, and the first clamping ring drives the operating ring and the adjusting inner cup to move, so that the operating strip drives the operating pipe to deform, making the threaded edge fit more tightly with the corrugated pipe and making it difficult for the corrugated pipe to detach from the mounting pipe.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. When the cable connector is installed on the electrical cabinet and the cable passes through the cable connector, the corrugated pipe is sleeved outside the mounting pipe, even if the corrugated pipe remains in the hose cup body and the embedded pipe extends to the other side of the cable connector, realizing the separation of the embedded pipe and the corrugated pipe; a sealing structure is formed between the second joint structure and the embedded pipe to prevent water vapor from entering the electrical cabinet housing from the outside, improving the sealing connection effect between the cable and the electrical cabinet; during the process of installing the compression nut on the first inner connecting pipe, the limiting ring pushes the first clamping ring to contact the outer edge, thereby pressing the outer edge tightly, making it difficult for the inner cup of the hose to move when the corrugated pipe is installed on the mounting pipe;

[0027] 2. The embedded pipe can be clamped by the arc-shaped block, the operating plate and the operating bolt, making it difficult for the embedded pipe to move. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following further describes the present application in detail Figures 1 - 7 with reference to the accompanying

[0038] Embodiment 1

[0039] This embodiment discloses a cable connector applied to a new energy electrical cabinet. Referring to Figure 1 , a cable connector applied to a new energy electrical cabinet includes a first joint structure 1, a second joint structure 2, and a third joint structure 3.

[0040] Referring to Figure 1 and Figure 2, the first joint structure 1 can be connected to the corrugated pipe. The first joint structure 1 includes a first joint body 11, a first inner pipe 12, a first outer pipe 13, a compression nut 14, a hose inner cup 15, and a first clamping ring 16.

[0041] Refer to Figure 1 and Figure 2 , the first inner pipe 12 is fixedly connected to the end face of the first joint body 11. The compression nut 14 is threadedly connected to the first inner pipe 12, and a limiting ring 141 is fixedly connected to the inner circumferential surface of the compression nut 14. The limiting ring 141 is located on the side of the first inner pipe 12 away from the first joint body 11.

[0042] Refer to Figure 2 , the hose inner cup 15 can be inserted into the first inner pipe 12. The hose inner cup 15 includes a mounting pipe 151, a bent portion 152, an outer edge 153, and a threaded edge 154.

[0043] Refer to Figure 2 and Figure 3 , the bent portion 152 can be inserted into the first inner pipe 12. The outer edge 153 is fixedly connected to one end of the bent portion 152. When the outer edge 153 abuts against the first inner pipe 12, the insertion of the hose inner cup 15 into the first inner pipe 12 is restricted.

[0044] According to Figure 2 and Figure 3 , the mounting pipe 151 is located inside the outer edge 153, and the mounting pipe 151 is fixedly connected to the side of the bent portion 152 away from the outer edge 153.

[0045] Refer to Figure 2 and Figure 3 , a threaded edge 154 is provided on the outer circumferential surface of the mounting pipe 151, and the end face of the mounting pipe 151 away from the bent portion 152 is fitted to the surface of the threaded edge 154 away from the bent portion 152. The threaded edge 154 can cooperate with the threaded groove on the inner wall of the corrugated pipe. A notch is provided on the end face of the mounting pipe 151 away from the bent portion 152 to make it easier for the corrugated pipe to be spiraled onto the outside of the mounting pipe 151. Further, the distance between the threaded edge 154 and the outer surface of the mounting pipe 151 gradually increases in the direction approaching the bent portion 152.

[0046] Refer to 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 a plastic part. When the compression nut 14 is connected to the first inner connecting pipe 12, the outer edge 153 is pressed against the first inner connecting pipe 12, the first clamping ring 16 is pressed against the side of the outer edge 153 away from the first inner connecting pipe 12, and the limiting ring 141 is pressed against the side of the first clamping ring 16 away from the first inner connecting pipe 12.

In other embodiments, the first clamping ring 16 is made of an elastic part. When the compression nut 14 is connected to the first inner connecting pipe 12, the reaction force generated during the elastic deformation of the first clamping ring 16 is applied to the limiting ring 141, achieving the anti-loosening effect. At the same time, the first clamping ring 16 will deform in the axial direction, causing the first clamping ring 16 to be pressed against the outer surface of the corrugated pipe, preventing the corrugated pipe from detaching from the installation pipe 151, and achieving the anti-detachment effect.

[0055] Referring to Figure 3 and Figure 4 , in other embodiments, a plurality of second joint structures 2 are provided. When two adjacent second joint structures 2 are connected and assembled with each other, the second inner connecting pipe 22 can be screwed into the adjacent second outer connecting pipe 23. The inclined surface of the second chamfer 212 can also provide a guiding function for the second clamping ring 24.

[0056] Referring to Figure 1 and Figure 5 , the third joint structure 3 can be installed on the electrical cabinet housing. The third joint structure 3 includes a third joint body 31, a third inner connecting pipe 32, a fourth inner connecting pipe 33, a washer 34, a locking nut 35 and a clamping assembly 36.

The clamping assembly 36 includes arc-shaped blocks 361, operation plates 362 and operation bolts 363. There are two arc-shaped blocks 361 and two operation plates 362 respectively.

[0059] Referring to Figure 1 and Figure 5 , the two arc-shaped blocks 361 are symmetric with each other about the axis of the third joint body 31. Two perforations 1511 are formed on the end faces of the two arc-shaped blocks 361 close to each other.

[0061] Referring to Figure 1 and Figure 5 , the rod part of the operation bolt 363 passes through an arc-shaped block 361 and the operation plate 362, and then the rod part of the operation bolt 363 is threadedly connected to the other arc-shaped block 361, so that the two arc-shaped blocks 361 can clamp the embedded pipe.

[0062] The implementation principle of Embodiment 1 is as follows: First step, pass the fourth inner connecting pipe 33 through the housing of the electrical cabinet, connect the lock nut 35 to the fourth inner connecting pipe 33, and connect the third joint structure 3 to the housing of the electrical cabinet. Second step, pass the embedded pipe through the first joint structure 1, the second joint structure 2 and the third joint structure 3 in sequence, and rotate the corrugated pipe to the outside of the installation pipe 151, so that the thread edge 154 is in the thread groove inside the corrugated pipe.

[0063] Third step, tighten the first outer connecting pipe 13 and the second inner connecting pipe 22, so that the second clamping ring 24 abuts against the inclined surface of the first chamfer 111. As the first outer connecting pipe 13 and the second inner connecting pipe 22 are tightened continuously, the second clamping ring 24 deforms towards the center, and the second clamping ring 24 drives the sealing ring 25 to deform, so that the sealing ring 25 abuts against, seals and pre-fixes the embedded pipe. Fourth step, tighten through the operation bolt 363, so that the two arc-shaped blocks 361 clamp the embedded pipe.

[0064] Embodiment 2

[0065] Referring to Figure 6 and Figure 7, the difference between this embodiment and Embodiment 1 is that eight through holes 1511 are formed on the outer circumferential surface of the mounting tube 151, and the eight through holes 1511 penetrate through the mounting tube 151 in a direction away from the bending portion 152. In other embodiments, the number of the through holes 1511 can also be set to four, six or other quantities.

[0066] Referring to Figure 6 and Figure 7 , an adjusting inner cup 17 is sleeved outside the hose inner cup 15. The adjusting inner cup 17 includes a first operating tube 171, an operating portion 172, a second operating tube 173 and an operating bar 174.

The first operating tube 171, the operating portion 172 and the second operating tube 173 enclose an operating cavity. The bending portion 152 and the mounting tube 151 can be inserted into the operating cavity.

[0068] Referring to Figure 6 and Figure 7 , the operating bar 174 is fixedly connected to the outer circumferential surface of the second operating tube 173, and the operating bar 174 can drive the mounting tube 151 to deform in a direction away from the midpoint of the second operating tube 173. An operating chamfer is formed on the operating bar 174, and the chamfer slope is arranged at the junction of the end face of the operating bar 174 facing the operating portion 172 and the outer arc surface of the operating bar 174.

[0069] Referring to Figure 6 and Figure 7 , eight operating blocks 175 are arranged on the end face of the first operating tube 171 away from the operating portion 172, and the eight operating blocks 175 are circumferentially and arrayedly distributed around the axis of the first operating tube 171.

[0070] Referring to Figure 6 and Figure 7 , an operating ring 176 is arranged on the side of the outer edge 153 away from the bending portion 152. The eight operating blocks 175 are all fixedly connected to the operating ring 176. When the operating bar 174 does not drive the mounting tube 151 to deform, a gap is left between the operating ring 176 and the outer edge 153.

[0071] The implementation principle of Embodiment 2 is as follows: After the corrugated pipe is installed on the installation pipe 151, continue to drive the compression nut 14 and the first inner connecting pipe 12 to be tightened, so that the limit ring 141 pushes the first clamping ring 16, and the first clamping ring 16 pushes the operation ring 176, that is, drive the adjustment inner cup 17 to move, so that the operation bar 174 drives the installation pipe 151 to deform, and makes the thread edge 154 fit more tightly with the corrugated pipe.
