[0038] like Figures 1 to 3 As shown, the embodiment of the utility model provides a distribution box 100 for connecting with the cable 6, and the distribution box 100 includes:

[0039] The box body 1 has a receiving cavity 11, in which a wiring terminal 111 is provided, and the wiring terminal 111 is used to connect with one end of the cable 6, and a threading hole 121 for threading the cable 6 is provided on a side wall 12 of the box body 1;

[0040] A box cover 2 is detachably connected to the box body 1, and is used to block the opening of the accommodating cavity 11;

[0041] And the threading plate 3 is detachably connected to the side wall 12 of the box body 1 with a threading hole 121. The threading plate 3 is used to block the threading hole 121. The threading plate 3 is configured to form a wire hole, which is configured to be connected to the threading hole 121 and used to thread the cable 6.

[0042] The end of the cable 6 away from the wiring terminal 111 is used to connect to an electrical device.

[0043] In addition, if Figures 1 to 3 As shown, the threading portion may include a first threading portion 31, a second threading portion 32 and a third threading portion 33 to adapt to multiple cables 6; it should be noted that this embodiment only takes the threading plate 3 including three threading portions as an example, and the specific number of the threading portions may be based on actual working conditions and is not limited.

[0044] The distribution box 100 provided in this embodiment takes the case of the cable 6 passing through the first wire hole 312 as an example. First, the terminal block 111 is fixedly connected to the bottom plate of the box body 1. Then, one end of the cable 6 is passed through the first wire hole 312 and the wire opening 121 on the wire plate 3 in sequence. Then, the wire plate 3 is connected to the side wall 12 of the box body 1 provided with the wire opening 121 to achieve the sealing of the wire opening 121. One end of the cable 6 passing through the wire opening 121 is connected to the terminal block 111. Finally, the box cover 2 is closed to complete the assembly.

[0045] Therefore, the structure of the distribution box 100 is simple, and there is no need for the snap-fitting of the positioning plate and the sealing groove. The sealing of the threading opening 121 can be achieved by directly connecting the threading plate 3 with the side wall 12 of the box body 1 having the threading opening 121. This improves the efficiency of assembly and disassembly, and also has the beneficial effect of ensuring the sealing of the distribution box 100.

[0046] According to an optional embodiment of the present invention, the size of the wire hole is configured to be smaller than the cross-sectional size of the cable 6 .

[0047] The size of the wire hole is smaller than the size of the cross section of the cable 6 , that is, when the cable 6 passes through the wire hole, the cable 6 can have an interference fit with the wire hole, thereby ensuring the sealing between the wire hole and the cable 6 .

[0048] In this embodiment, taking the first wire passing hole 312 as an example, when the cable 6 passes through the first wire passing hole 312, the outer wall of the cable 6 can fit tightly with the first wire passing hole 312, thereby further ensuring the overall sealing of the distribution box 100.

[0049] According to an optional embodiment of the present invention, the threading plate 3 includes a main body portion 34 and at least one threading portion, and the threading portion is configured to be separable from the main body portion 34 and to form a threading hole on the surface of the main body portion 34 .

[0050] In this embodiment, taking the example of the cable 6 passing through the first wire hole 312 formed by separating the first wire threading portion 31 and the main body portion 34, the terminal 111 is first fixedly connected to the bottom plate of the box body 1, and then the first wire threading portion 31 is separated relative to the main body portion 34 to form the first wire hole 312 on the surface of the main body portion 34, and then one end of the cable 6 is passed through the first wire hole 312 and the wire threading opening 121 in sequence, wherein the size of the first wire hole 312 is configured to be smaller than the cross-sectional size of the cable 6 to ensure that the two can be interference fit when the cable 6 is passed through the first wire hole 312, and then the wire threading plate 3 is connected to the side wall 12 of the box body 1 provided with the wire threading opening 121 to achieve sealing of the wire threading opening 121, and one end of the cable 6 passing through the wire threading opening 121 is connected to the terminal 111, and finally the box cover 2 is closed to complete the assembly.

[0051] Therefore, this arrangement can ensure the sealing of the wire threading port 121 while taking into account the sealing between the cable 6 and the wire hole, and has a simple structure, thereby ensuring assembly efficiency.

[0052] According to an optional embodiment of the present invention, there are multiple threading parts, and the sizes of the threading holes formed on the surface of the main body 34 by each threading part are different along the direction parallel to the side wall 12 provided with the threading opening 121.

[0053] In this embodiment, the wire passing holes formed by each threading portion are arranged one-to-one corresponding to cables 6 of different sizes. For example, the first wire passing hole 312 formed by separating the first wire threading portion 31 from the main body portion 34 and the second wire passing hole 322 formed by separating the second wire threading portion 32 from the main body portion 34 should have different sizes to be suitable for threading cables 6 of different diameters.

[0054] Therefore, the sizes of cables 6 adapted to the multiple threading parts are different, so that the distribution box 100 can be connected to multiple cables 6 with different diameters.

[0055] Continue to refer Figures 1 to 3 According to an optional embodiment of the utility model, at least one threading portion includes a plurality of annular sub-portions, and the orthographic projections of the plurality of sub-portions on the side wall 12 provided with the threading opening 121 are a plurality of concentric circles, each concentric circle has a different diameter, and the plurality of sub-portions are connected by thin walls, and each sub-portion is configured to be separable from the main body portion 34 and form a threading hole on the surface of the main body portion 34.

[0056] In this embodiment, since the diameters of the cables 6 are different under actual working conditions, in order to improve the adaptability between the distribution box 100 and the cables 6, each threading portion is configured to be able to pass through cables 6 of various sizes. Figure 1 , Figure 1 The distribution box 100 in the example is suitable for cables of three different diameters.

[0057] Similarly, taking the threading plate 3 including the first threading portion 31 as an example, when manufacturing the threading plate 3, the threading plate 3 can be a complete plate-like structure without the first threading hole 312, and the position of the first sub-portion 311 is marked on the threading plate 3. When it is determined what diameter of cable 6 the first threading portion 31 needs to pass through, the first sub-portion 311 of the corresponding size on the first threading portion 31 is cut along its annular contour to form the first threading hole 312 for passing the cable 6 of the diameter. Figures 1 to 3 As shown, it can be seen that the first threading portion 31 of this embodiment includes four first sub-portions 311; Figure 3 , Figure 3 The annular contour of the first sub-portion 311 with the smallest aperture has been cut, thereby forming a first wire-passing hole 312 .

[0058] Therefore, this configuration further improves the compatibility between the distribution box 100 and different cables 6 .

[0059] Continue to refer Figure 3 It should be noted that, when the threading plate 3 also includes a second threading portion 32 and a third threading portion 33, the second threading portion 32 may include a plurality of second sub-portions 321, and the third threading portion 33 may include a plurality of third sub-portions 331. The manner in which the second sub-portion 321 forms the second threading hole 322 and the manner in which the third sub-portion 331 forms the third threading hole 332 are both the same as the manner in which the first sub-portion 311 forms the first threading hole 312, and will not be repeated herein.

[0060] According to an optional embodiment of the present invention, the multiple sub-sections are in the same plane.

[0061] In this embodiment, taking the threading plate including the first threading portion 31 as an example, the multiple first sub-portions 311 of the first threading portion 31 can be in the same plane, for example, the multiple first sub-portions 311 and the main body portion 34 are all in the same plane; in this way, when it is necessary to form a first threading hole 312, a tool can be used to cut along the annular contour of a first sub-portion 311 to form a first threading hole 312 corresponding to the annular contour of the first sub-portion 311 on the main body portion 34.

[0062] Similarly, when the threading plate 3 also includes a second threading portion 32 and a third threading portion 33, the manner in which the second sub-portion 321 forms the second threading hole 322 and the manner in which the third sub-portion 331 forms the third threading hole 332 are the same as the manner in which the first sub-portion 311 forms the first threading hole 312, and will not be repeated herein.

[0063] According to an optional embodiment of the present utility model, a plurality of sub-parts are arranged in a direction away from the box body 1 to form a protrusion.

[0064] In this embodiment, taking the threading plate including the first threading portion 31 as an example, a plurality of first sub-portions 311 are arranged in a direction away from the box body 1 to form a protrusion. When it is necessary to form a first threading hole 312, scissors can be used to cut along the annular contour of a first sub-portion 311 to form a first threading hole 312 corresponding to the annular contour of the first sub-portion 311 on the main body 34. It is easy to understand that, among the plurality of first sub-portions 311, the farther the first sub-portion 311 is from the box body 1 along the direction perpendicular to the side wall 12 provided with the threading opening, the smaller the aperture of the first threading hole 312 formed after it is cut.

[0065] Similarly, when the threading plate 3 also includes a second threading portion 32 and a third threading portion 33, the manner in which the second sub-portion 321 forms the second threading hole 322 and the manner in which the third sub-portion 331 forms the third threading hole 332 are the same as the manner in which the first sub-portion 311 forms the first threading hole 312, and will not be repeated herein.

[0066] Therefore, the arrangement of the plurality of sub-parts in a direction away from the box body 1 to form a protrusion makes the operation of forming the wire passing hole simpler and more convenient.

[0067] According to an optional embodiment of the present invention, the main body portion 34 and the threading portion are an integrally formed rubber-coated component.

[0068] In this embodiment, the sealing performance of the rubber-coated material is good. When the threading plate 3 is connected to the side wall 12 of the box body 1 provided with the threading opening 121, the threading opening 121 can be better blocked, thereby further improving the overall sealing performance of the distribution box 100. In addition, the rubber-coated material is easy to cut or trim. When it is necessary to separate the threading part from the main body 34 and form a wire hole on the surface of the main body 34, the operation is more convenient.

[0069] like Figure 1 and Figure 2 As shown, according to an optional embodiment of the present utility model, the threading plate 3 is detachably connected to the side wall 12 of the box body 1 provided with the threading hole 121 through a first fixing member.

[0070] In this embodiment, the first fixing member includes a first screw 51; the threading plate 3 and the side wall 12 of the box body 1 are connected by the first screw 51, so that the threading plate 3 can be pressed relative to the side wall 12. On the premise of ensuring the reliability of the connection, the threading plate 3 made of rubber-coated material can further ensure the sealing of the threading port 121 on the side wall 12, and the threaded connection method is also convenient for installation and disassembly.

[0071] According to an optional embodiment of the utility model, there are multiple first fixing members, and taking the first fixing member as the first screw 51 as an example, the threading plate 3 is provided with multiple first threaded holes 52 that cooperate with the first screw 51, and the multiple first threaded holes 52 are evenly spaced around the circumference of the threading plate 3, and the first screws 51 and the first threaded holes 52 are arranged one by one.

[0072] In this embodiment, the side wall 12 of the box body 1 having the threading hole 121 may also be provided with a plurality of first threaded holes 52 that cooperate with the first screws 51. The plurality of first screws 51 may be evenly spaced and distributed on the box cover 2. For example, four first screws 51 are provided. Figures 1 to 3 The four first threaded holes 52 on the threading plate 3 are arranged at the four corners of the threading plate 3, and the four first threaded holes 52 on the side wall 12 of the box body 1 with a threading port 121 are arranged at the four corners of the side wall 12. In this way, when the first screw 51 is tightened, the threading plate 3 and the side wall 12 can be evenly stressed. On the premise of ensuring the sealing of the threading port 121, the service life of the threading plate 3 and the box body 1 is also guaranteed to a certain extent.

[0073] refer to Figures 1 to 3 According to an optional embodiment of the present invention, there are multiple threading parts and multiple wiring terminals 111; the multiple threading parts and the multiple wiring terminals 111 are arranged in a one-to-one correspondence.

[0074] In this embodiment, when the distribution box 100 needs to connect multiple cables 6, each cable 6 can be passed through the corresponding threading portion and threading port 121 in turn, and then the cable 6 is connected to the corresponding terminal 111.

[0075] Therefore, this configuration can realize the connection between the distribution box 100 and multiple cables 6.

[0076] Among them, the multiple threading parts should be arranged at intervals to prevent the multiple cables 6 from interfering with each other; Figure 1 Taking the distribution box 100 connecting three cables 6 as an example, at least three wiring terminals 111 are provided in the accommodating cavity 11 of the distribution box 100, and there are at least three threading parts, and the three threading parts (i.e., the first threading part 31, the second threading part 32 and the third threading part 33) are arranged at intervals on the threading plate 3, so that each cable 6 is respectively corresponding to a threading part and a wiring terminal 111.

[0077] like Figure 1 As shown, according to an optional embodiment of the present utility model, a sealing strip 112 cooperating with the box cover 2 is provided at the opening of the accommodating cavity 11 .

[0078] In this embodiment, since the box cover 2 is used to seal the opening of the accommodating cavity 11, a sealing strip 112 that cooperates with the box cover 2 is provided at the opening of the accommodating cavity 11. When the box cover 2 seals the opening, the gap between the box cover 2 and the opening will be sealed by the sealing strip 112, thereby further improving the overall sealing of the distribution box 100.

[0079] refer to Figure 1 According to an optional embodiment of the present invention, the sealing strip 112 is an annular structure, and the sealing strip 112 is arranged around the circumference of the opening.

[0080] In this embodiment, since the annular sealing strip 112 can seal the entire circumference of the opening of the accommodating chamber 11, when the box cover 2 seals the opening of the accommodating chamber 11, the sealing strip 112 can seal all possible gaps between the box cover 2 and the opening, thereby more effectively improving the overall sealing of the distribution box 100.

[0081] Continue to refer Figure 1 According to an optional embodiment of the present utility model, the box cover 2 is detachably connected to the box body 1 through a second fixing member.

[0082] In this embodiment, the second fixing member includes a second screw 41, and the second screw 41 can be multiple, and the multiple second screws 41 are distributed at intervals. The box cover 2 and the box body 1 are both provided with multiple second threaded holes 42 that cooperate with the second screws 41; during assembly, the second screws 41 are sequentially passed through the two second threaded holes 42 that cooperate with them, and each second screw 41 is installed in this way. Finally, all the second screws 41 are tightened to complete the assembly of the box cover 2 and the box body 1.

[0083] Therefore, the box cover 2 and the box body 1 are threadedly connected by the second screw 41, so that the box cover 2 can be pressed relative to the box body 1. On the premise of ensuring the reliability of the connection, the sealing strip 112 can further ensure the sealing of the opening, and the threaded connection method is also convenient for installation and disassembly.

[0084] In addition, a plurality of second screws 41 can be evenly spaced and distributed on the box cover 2. For example, four second screws 41 are provided. Figure 1 As shown, the four second threaded holes 42 on the box cover 2 are arranged at the four corners of the box cover 2, and the four second threaded holes 42 on the box body 1 are arranged at the four corners of the upper surface of the box body 1. In this way, when the second screws 41 are tightened, the box cover 2 and the box body 1 can be evenly stressed. On the premise of ensuring the sealing of the opening, the service life of the box cover 2 and the box body 1 is also guaranteed to a certain extent.

[0085] According to an optional embodiment of the present invention, the box cover 2 can be rotatably connected to the box body 1 via a rotating shaft (not shown in the figure) so that the box cover 2 has an open state and a closed state relative to the opening of the accommodating chamber 11.

[0086] In this embodiment, in order to further improve the integration of the distribution box 100, a rotating shaft can be set on the outside of a side wall of the box body 1, and an edge of the box cover 2 is rotatably connected to the rotating shaft. The box cover 2 is rotated around the rotating shaft to approach and move away from the opening of the accommodating cavity 11, so as to realize the switching of the box cover 2 between an open state and a closed state relative to the opening.

[0087] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
