[0054] The following further elaborates on the detailed implementation mode of the present utility model in conjunction with the attached drawings.

[0055] As Figures 1 - 18 shown, the junction box with a solenoid valve coil includes a box body 1 and a coil seat 2. The box body 1 is internally provided with a mounting seat 3, and a metal part 1 is arranged on the mounting seat 3. A metal part 2 is arranged on one side of the coil seat 2, and the metal part 2 is connected to the metal part 1 to achieve electrical connection because metal can conduct electricity to transmit current and signals.

[0056] At the same time, as Figures 1 - 18 shown, it can be seen that in order to facilitate the installation of wires, a rotating clamping structure is provided, but there are many styles of the rotating clamping structure, and there are also differences in the structures of corresponding parts.

[0057] Embodiment 1: As Figures 1 - 8 shown, first, a rotatable paddle 6 is arranged on the mounting seat 3, and an elastic member is arranged between the paddle 6 and the metal part 1, and the gap between the elastic member and the metal part 1 is used to place wires.

[0058] Therefore, during actual use, by rotating the paddle 6, pressure is applied to the elastic member, causing the gap between the elastic member and the first metal member 4 to expand, allowing the wire to enter. Then, the elastic member returns to its original position due to its own elasticity and fits with the first metal member 4 to clamp the wire, and the return of the elastic member drives the paddle 6 to return to its original position.

[0059] Therefore, the elastic member and the first metal member 4 are adapted to each other to clamp the wire, thereby realizing the installation of the wire. Compared with the prior art, such installation can be achieved by rotating the paddle 6 and inserting the wire, so the installation is very convenient. Moreover, even if there is vibration, due to the presence of the elastic member, it can play a buffering and offsetting role, thus avoiding loosening and ensuring the stability of the wire installation.

[0060] The rotation structure of the paddle 6 is as follows: First, rotating shafts 63 are provided on both sides of the paddle 6, and the cover 32 of the mounting base 3 is provided with an assembly groove 322 corresponding to the rotating shafts 63, and the rotating shafts 63 are located in the assembly groove 322 and rotate in the assembly groove 322.

[0061] At the same time, the elastic member is a spring piece 71. One end of the spring piece 71 is provided with a hole 711, and the other end of the spring piece 71 is bent and located in the hole 711. One end of the first metal member 4 passes through the hole 711 and protrudes, and the gap between the end of the spring piece 71 located in the hole 711 and the first metal member 4 is used to place the wire.

[0062] Therefore, during actual use, by rotating the paddle 6, pressure is applied to the elastic member, causing the end of the spring piece 71 located in the hole 711 to tilt and the gap between the elastic member and the first metal member 4 to expand. Moreover, the spring piece 71 can also be of other structures as long as it can achieve clamping and resetting.

[0063] Secondly, the structure between the second metal member 5 and the first metal member 4 is as follows Figure 3 As shown, first, the first metal member 4 is provided with a card slot 42 on the side close to the second metal member 5, and one end of the second metal member 5 close to the first metal member 4 is located in the card slot 42.

[0064] Moreover, the structure between the second metal member 5 and the coil seat 2 is as follows Figure 5 As shown, it can be seen that they are directly connected, that is, there are no redundant components. Compared with the prior art, one plate member is missing in the present utility model, so the structure is more simplified.

[0065] The specific structure is as follows: First, the coil seat 2 is provided with a clamping groove 21, and one end of the second metal member 5 away from the first metal member 4 is located in the clamping groove 21. At the same time, a first connecting column 22 is provided on one side of the coil seat 2, and a second connecting column 51 is provided on the second metal member 5 corresponding to the first connecting column 22, and the first connecting column 22 is connected to the second connecting column 51.

[0066] Among them, the first connecting column 22 and the second connecting column 51 are made of metal, and the coil on the coil base 2 will be wound around the first connecting column 22. Electrical connection is achieved through the connection between the first connecting column 22 and the second connecting column 51 because metal conducts electricity and can transmit current and signals. At the same time, other forms can also be adopted for wire connection, as long as they are made of conductive materials.

[0067] Secondly, the solenoid valve also needs to be connected to the ground wire. Therefore, a connection seat 8 is provided on the outside of the coil base 2. The connection seat 8 is provided with a connection groove 81, and a convex block 811 is provided inside the connection groove 81. At the same time, one end of the second metal part 5 away from the first metal part 4 is provided with a connecting plate 52, and the connecting plate 52 is located in the connection groove 81 and is provided with a card hole 521 corresponding to the convex block 811.

[0068] At the same time, the connection seat 8 is C-shaped, and the coil base 2 is located at the opening of the C-shape. A housing 10 is provided on the outside of the coil base 2 and the connection seat 8 to play a protective role. Moreover, the connection between the connection seat 8 and the coil base 2 is a screw connection, that is, a screw connection is adopted between the bottom of the coil base 2 and the connection seat 8. Secondly, the connection between the connection seat 8 and the mounting seat 3 is as follows: First, a hollow column 82 is provided on one side of the connection seat 8. The column 82 is provided with threads and penetrates into the mounting seat 3. A screw passes through the box body 1 and penetrates into the mounting seat 3 to be connected to the column 82, thereby realizing the connection between the connection seat 8 and the mounting seat 3.

[0069] As Figure 6 shown, the structure of the mounting seat 3 is as follows: First, the mounting seat 3 includes a base 31 and a lid 32 provided on the base 31. The lid 32 is connected to the box body 1, and a dial 6 is rotatably provided on the lid 32. The base 31 and the lid 32 are respectively provided with a first channel 312 and a second channel 321. The first channel 312 is for placing the first metal part 4 and for the second metal part 5 to penetrate, and the second channel 321 is for the wire to penetrate. The lid 32 is provided with an assembly hole one 329, and one end of the first metal part 4 away from the second metal part 5 passes through the assembly hole one 329.

[0070] Therefore, in the actual use process, connection and limitation are achieved by one end of the first metal part 4 passing through the assembly hole one 329. One side of the lid 32 is provided with an assembly plate 33. The assembly plate 33 is provided with an assembly hole two 331. One end of the first metal part 4 away from the second metal part 5 passes through the assembly hole one 329 and the assembly hole two 331 in sequence. The assembly plate 33 is provided with a fifth channel 332 corresponding to the second channel 321 for the wire to penetrate.

[0071] The structure between the lid 32 and the box body 1 is as follows: First, a connecting seat 8 is arranged outside the coil base 2, and a hollow assembling post one 323 is arranged on one side of the lid 32. Moreover, a channel three 313 and a channel four 324 are respectively opened in the base 31 and the lid 32 corresponding to the assembling post one 323. And a hollow assembling post two 11 is arranged inside the box body 1. At least two clamping plates 325 are arranged inside the assembling post one 323, and one end of the clamping plate 325 far away from the lid 32 is located inside the assembling post two 11, and a clamping block 326 is arranged on the outside of this end.

[0072] Therefore, during actual use, when the fastener passes through the assembling post two 11, the assembling post one 323, the channel three 313 and the channel four 324 and is thus connected to the connecting seat 8, the fastener will exert pressure on the clamping plate 325 to make the clamping plate 325 expand outwards and make the clamping block 326 abut against the inner wall of the assembling post two 11. The fastener is a screw, and the assembling plate 33 is sleeved outside the assembling post one 323.

[0073] Meanwhile, the structure between the base 31 and the lid 32 is as follows: First, an installation groove one 314 is arranged outside the base 31, and a buckle 315 is arranged inside the installation groove one 314. Moreover, the lid 32 is provided with a convex plate 327, and the convex plate 327 is located inside the installation groove one 314 and a clamping hole 328 is opened corresponding to the buckle 315.

[0074] Therefore, during actual use, the connection is realized by the adaptation of the clamping hole 328 and the buckle 315.

[0075] As Figure 4 shown, a hollow installation post 12 is arranged on one side of the box body 1, and an opening 13 is opened in the box body 1 corresponding to the installation post 12. Moreover, the diameter of the opening 13 is smaller than the inner diameter of the installation post 12. And a nut 91 is threadedly connected to the inner wall of the installation post 12. The nut 91 is hollowly arranged to allow the wire to pass through. And a clamping member 92 is arranged at one end of the nut 91 located inside the installation post 12.

[0076] Meanwhile, a plurality of clamping plates 921 are evenly distributed at one end of the clamping member 92 close to the installation seat 3, and an interval is arranged between two adjacent clamping plates 921. Therefore, during actual use, by the outer side of the opening 13 abutting against the clamping plates 921, when the nut 91 is tightened, the clamping plates 921 will approach each other and approach the wire to wrap the wire, so as to limit the wire.

[0077] The clamping member 92 can be integrally formed with the nut 91, such as the use of the patent number 2023212983889, or the clamping member 92 and the nut 91 are separate. First, the clamping member 92 is placed in, and by tightening the nut 91, the nut 91 will move inwards and push the clamping member 92 to move until it contacts the opening 13.

[0078] Embodiment 2: This embodiment is basically the same as Embodiment 1, except for the specific structures of the second metal part 5 and the first metal part 4. The second metal part 5 in Embodiment 1 is in the form of a sheet, while in this embodiment it is long and strip-shaped. Therefore, the connection structures corresponding to the first metal part 4 are also different.

[0079] As Figures 9 - 13 shown, first, the first metal part 4 includes a main sheet 43 and an auxiliary sheet 44. The auxiliary sheet 44 is located below the main sheet 43 and connected to the main sheet 43. The gap between the main sheet 43 and the auxiliary sheet 44 is used to place the second metal part 5, and one end of the second metal part 5 close to the first metal part 4 is located between the main sheet 43 and the auxiliary sheet 44.

[0080] At the same time, the structure between the second metal part 5 and the coil base 2 is, as Figure 11 shown, it can be seen that they are directly connected, that is, there are no extra components. Compared with the existing ones, one plate part is missing in this utility model, so the structure is more simplified.

[0081] The specific structure is as follows: First, the coil base 2 is provided with a clamping groove 21, and one end of the second metal part 5 away from the first metal part 4 is located in the clamping groove 21. At the same time, a connecting post 22 is provided on one side of the coil base 2, and the second metal part 5 is provided with an arc-shaped plate 53 corresponding to the connecting post 22, and the connecting post 22 is connected to the arc-shaped plate 53.

[0082] Among them, the connecting post 22 and the arc-shaped plate 53 are made of metal, and the coil on the coil base 2 will be wound around the connecting post 22, and the electrical connection is realized through the connection between the connecting post 22 and the arc-shaped plate 53, because metal can conduct electricity and thus transmit current and signals. At the same time, other forms can also be used for wire connection, as long as they are made of two conductive materials.

[0083] Secondly, the solenoid valve also needs to be connected to the ground wire. Therefore, a connecting seat 8 is provided on the outside of the coil base 2. The connecting seat 8 is provided with a connecting groove 81, and a convex block 811 is arranged inside the connecting groove 81. At the same time, a connecting plate 52 is arranged at one end of the second metal part 5 away from the first metal part 4, and the connecting plate 52 is located in the connecting groove 81 and is provided with a clamping hole 521 corresponding to the convex block 811.

[0084] At the same time, the connecting seat 8 is in a C shape, and the coil base 2 is located at the opening of the C shape. A housing 10 is arranged on the outside of the coil base 2 and the connecting seat 8 to play a protective role. Moreover, the connection between the connecting seat 8 and the coil base 2 is a screw connection, that is, a screw connection is adopted between the bottom of the coil base 2 and the connecting seat 8. Secondly, the connection between the connecting seat 8 and the mounting seat 3 is as follows: First, a hollow column 82 is provided on one side of the connecting seat 8. The column 82 is provided with threads and penetrates into the mounting seat 3. A screw passes through the box body 1 and penetrates into the mounting seat 3 to be connected to the column 82, thereby realizing the connection between the connecting seat 8 and the mounting seat 3.

[0085] Embodiment 3: This embodiment is basically the same as Embodiment 1, except for the rotating clamping structure. In Embodiment 1, the elastic member and the first metal member are adapted to each other, while in this embodiment, the paddle and the first metal member are adapted to each other.

[0086] As Figures 14 - 18 shown, a rotatable paddle 6 is provided on the mounting base 3, and an elastic member is provided between the paddle 6 and the mounting base 3, and the gap between the paddle 6 and the first metal member 4 is used to place the wire.

[0087] Therefore, during actual use, by rotating the paddle 6, pressure is applied to the elastic member, and the gap between the paddle 6 and the first metal member 4 is enlarged so that the wire can enter. And the paddle 6 is reset under the elasticity of the elastic member itself and is adapted to the first metal member 4 to clamp the wire.

[0088] Therefore, the paddle 6 and the first metal member 4 are adapted to each other to clamp the wire and thus realize the installation of the wire. Compared with the prior art, such installation can be achieved by rotating the paddle 6 and inserting the wire, so the installation is very convenient. Moreover, even if there is vibration, due to the presence of the elastic member, it can play a role in buffering and offsetting, thus avoiding loosening and ensuring the stability of the wire installation.

[0089] The structure of the paddle 6: First, the paddle 6 is provided with a clamping portion 61, and the gap between the clamping portion 61 and the first metal member 4 is used to place the wire. Therefore, during actual use, by rotating the paddle 6, the clamping portion 61 is moved away from the first metal member 4 and the gap between the clamping portion 61 and the first metal member 4 is enlarged.

[0090] And the elastic member can be a structure such as a leaf spring 71 or a spring 72, as long as it can achieve reset. And when the elastic member is a spring 72, the installation structure of the spring 72 is: First, the mounting base 3 is provided with a second mounting groove 311, and the paddle 6 is provided with a protrusion 62, and one end of the spring 72 is located in the second mounting groove 311, and the other end of the spring 72 is sleeved outside the protrusion 62.

[0091] At the same time, in order to make the clamping effect on the wire better, the outer surface of the end of the clamping portion 61 close to the first metal member 4 is an outwardly convex arc surface and is provided with serrations, and the first metal member 4 is provided with a groove 41 corresponding to the clamping portion 61.

[0092] Therefore, during actual use, through the setting of the outwardly convex arc surface, serrations and the groove 41, the contact area can be increased, and thus the clamping effect on the wire is better.

[0093] The above has shown and described the basic principles, main features and advantages of the present utility model. At the same time, the present utility model is not limited by the above embodiments. Therefore, without departing from the principles and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
