Description

Technical Field

[0001] The present invention relates to the technical field of power pipeline arrangement, and in particular to a pipeline system. Background Art

[0002] In building decoration, the junction box is one of the electrical auxiliary materials. The junction box is usually embedded in the wall or the ground for the passage of cables. The cables used in decoration need to pass through the conduit. At the joint of the cable, for example, when the cable line is relatively long or the cable needs to be turned, the junction box is used as a transition to protect the cables and arrange the wiring reasonably. The junction box is connected to the mounting parts, such as switch panels, socket panels, crossing box panels or sealing box panels, and is fixed to the wall or the ground for switching circuits or plugging in electrical power for users' daily use. The existing junction box includes a box body with an opening at the top, and a plurality of holes are reserved on the side of the box body for the conduit to pass through. During actual installation, the reserved holes of the corresponding number and position are opened as needed to connect the conduit to the box body. When wiring, multiple wire conduits are connected in sequence to form a wiring pipeline. For example, the wire conduit on the junction box needs to be connected to another wire conduit to form a wiring pipeline. On the one hand, the interfaces between the wire conduits have poor sealing properties and cannot effectively prevent water from entering, posing a safety hazard. On the other hand, the wire conduits are connected by hot melting, electric melting or steel-plastic transition joints, making installation and maintenance inconvenient. Summary of the Invention

[0003] The purpose of the present invention is to solve the problem that the interfaces between interconnected threading pipes are poorly sealed, cannot be effectively waterproofed, and cause safety hazards, and the existing threading pipe connection method makes installation and maintenance inconvenient.

Furthermore, the conduit connector locks the first and second conduits to install the piping system and releases them to remove the piping system. This simplifies installation and removal of the conduit connector, improving installation and maintenance efficiency.

[0068] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0069] In building renovation, a junction box is one of the electrical auxiliary materials. It is usually embedded in a wall or floor to allow cables to pass through. In the present invention, junction boxes include but are not limited to 86 junction boxes, 120 junction boxes, and 118 junction boxes.

[0070] refer to Figure 1 The first embodiment of the present invention provides a wire box 1. For the convenience of description, Figure 1 The wire box shown is described as a first wire box 1a, which includes a first box body 11a and a wire tube 12. The first box body 11a and the wire tube 12 are integrally formed. For example, the first box body 11a and the wire tube 12 are integrally formed by open mold casting.

[0071] In this embodiment, reference Figure 1 The first box body 11a is cylindrical with an open top. The first box body 11a includes a receiving chamber 111 with an open top 112 and a closed bottom 113. Specifically, the receiving chamber 111 of the first box body 11a is formed by the sidewalls and bottom 113 of the first box body 11a and is used to accommodate cables.

[0072] refer to Figure 1 and Figure 2 , a mounting lug 13 is provided on the inner side wall 114 of the accommodating cavity 111. In this embodiment, the mounting lug 13 is integrally formed with the first box body 11a. Alternatively, the mounting lug 13 is connected to the first box body 11a. For example, the mounting lug 13 is detachably connected to the first box body 11a, such as by snapping; or the mounting lug 13 is fixedly connected to the first box body 11a, such as by welding. Figure 1 and Figure 3Mounting lugs 13 include a first mounting lug 131 and a second mounting lug 132. The first and second mounting lugs 131, 132 extend along a radial direction Rr of the accommodating cavity 111 and are disposed opposite each other along the radial direction Rr of the accommodating cavity 111 on the inner sidewall 114 of the accommodating cavity 111. The first and second mounting lugs 131, 132 are respectively configured to connect to a mounting member, such that the mounting member is connected to the first junction box 1a via the first and second mounting lugs 131, 132, thereby securing the mounting member to the wall. Exemplarily, the mounting member is a switch panel, a socket panel, a junction box panel, or a blanking box panel.

[0073] In this embodiment, the threading tube 12 is disposed on the outer wall 115 of the accommodating cavity 111 and is in communication with the accommodating cavity 111. Figure 1 The threading tube 12 and the accommodating chamber 111 have a connecting portion 121 , and the threading tube 12 is connected to the accommodating chamber 111 through the connecting portion 121 so that the cable can pass through the threading tube 12 and the accommodating chamber 111 .

[0074] By adopting the above technical solution, the first wire box 1a is configured to be integrally formed, that is, the first box body 11a and the wire threading tube 12 are integrally formed, so that the first wire box 1a has no welding or connection gaps, thereby enhancing the sealing of the first wire box 1a, effectively waterproofing, and preventing concrete and other building materials from falling in during pre-embedding.

[0075] In some possible embodiments provided by the present invention, the threading tube 12 includes at least one. For example, for example, referring to Figure 1 The first wiring box 1a is provided with a threading tube 12, and the threading tube 12 extends in a direction Yc. In this embodiment, the cable enters the accommodating cavity 111 of the first wiring box 1a through the threading tube 12 and passes through the top opening 112 of the accommodating cavity 111.

[0076] In this embodiment, the first wiring box 1a further includes a first cover 2 (eg Figure 13 and Figure 14 (As shown in the figure), the first cover 2 covers the top opening 112 of the accommodating cavity 111 and is sealed therewith. A cable outlet tube 333 (not shown) is provided axially on the first cover 2. Cables enter the accommodating cavity 111 of the first wiring box 1a through the cable outlet tube 12 and exit through the cable outlet tube 333.

[0077] In some other possible embodiments provided by the present invention, more specifically, referring to Figure 1 Combine Figure 31 The first wiring box 1a further includes a third cover 10, which covers the top opening 112 of the accommodating cavity 111 and is sealed with the top opening 112. Along the axial direction Z10 of the third cover 10, a wire outlet tube 333 is provided on the third cover 10. Figure 1 Combined with Figure 12 The cable enters the accommodating cavity 111 of the first wire box 1a through the wire tube 12 and exits through the outlet tube 333.

[0078] In some other possible embodiments, the outlet pipe 333 is not limited to being provided on the first cover 2 and the third cover 10. The outlet pipe 333 may also be provided on covers of other shapes and styles for allowing cables to pass through.

[0079] For example, refer to Figure 3 and Figure 4 , the wire threading tubes 12 include two. In this embodiment, the second wiring box 1b is provided with two wire threading tubes 12, and the extension direction of the two wire threading tubes 12 is Yc. The two wire threading tubes 12 are arranged on the same side of the first box body 11a, that is, relative to the radial direction Rr of the accommodating cavity 111 where the first mounting lug 131 and the second mounting lug 132 are located, the two wire threading tubes 12 are arranged on the same side of the first box body 11a. One of the wire threading tubes 12 serves as the entrance of the cable, and the other wire threading tube 12 serves as the outlet of the cable, or both wire threading tubes 12 serve as the entrance of the cable, and the cable passes through the outlet tube 333 as described above. The second wiring box 1b is suitable for the situation of wiring on the same side. For example, as reference Figure 5 The third wire box 1c includes four wire tubes 12. With respect to the radial direction Rr of the accommodating cavity 111 where the first mounting lug 131 and the second mounting lug 132 are located, the four wire tubes 12 are respectively arranged on both sides of the first box body 11a. In this embodiment, at least two wire tubes 12 are located on the same straight line. For example, referring to Figure 6 The fourth wire box 1d includes six wire tubes 12, and the six wire tubes 12 are distributed along the outer wall 115. Figure 7 The fifth wire box 1e includes eight wire threading tubes 12, and the eight wire threading tubes 12 are evenly distributed along the outer side wall 115.

[0080] For example, refer to Figure 8 , the sixth wire box 1f includes a wire tube 12. For example, referring to Figure 9 The seventh wiring box 1g includes two wire threading tubes 12, and the extension direction Yc of the two wire threading tubes 12 is in the same direction as the radial direction Rr of the accommodating cavity 111 where the first mounting lug 131 and the second mounting lug 132 are located. That is, the two wire threading tubes 12 are arranged on the outer side wall 115 of the second box body 11b, and are respectively located on the outside of the first mounting lug 131 and the second mounting lug 132. The two wire threading tubes 12 are located on the same straight line, one of the wire threading tubes 12 serves as the entrance of the cable, and the other wire threading tube 12 serves as the outlet of the cable, or both of the wire threading tubes 12 serve as the entrance of the cable, and the cable passes through the outlet tube 333 as described above. The seventh wiring box 1g is suitable for wiring on both sides. For another example, referring to Figure 10, the eighth wire box 1h includes three wire tubes 12. For example, referring to Figure 11 The ninth wiring box 1i includes four wire threading tubes 12, which are evenly distributed along the circumference of the second box body 11b on the outer wall of the second box body 11b. In other possible embodiments, the angle between the extension direction Yc of the wire threading tubes 12 and the outer wall 115 of the box body 11, projected along the axial direction Zr of the accommodating cavity 111 of the box body 11, is greater than 0 degrees and less than 180 degrees to meet actual wiring requirements.

[0081] In some possible embodiments, a plurality of wire threading tubes 12 are arranged on the outer side wall 115 of the wire box body 11 from top to bottom along the axial direction Zr of the accommodating cavity 111 .

[0082] In other embodiments of the present invention, there is no restriction on the number and setting position of the threading tubes 12, and users can make personalized settings according to actual needs.

[0083] In some other possible embodiments provided by the present invention, refer to Figure 1 and Figure 3 The threading tube 12 is perpendicular to the outer side wall 115 of the accommodating cavity 111. That is, the extending direction Yc of the threading tube 12 is perpendicular to the axial direction Zr of the accommodating cavity 111.

[0084] In some other possible embodiments provided by the present invention, the cross-sectional shape of the threading tube 12 includes at least one of a polygon, a circle, an ellipse and an irregular shape, and the present invention is not limited thereto. Figure 1 、 Figures 3 to 11 The cross-sectional shape of the threading tube 12 is circular, or the cross-sectional shape of the threading tube 12 is hexagonal (not shown in the figure).

[0085] In some possible embodiments of the present invention, the cross-sectional shape of the accommodating cavity 111 includes any one of polygonal, circular, elliptical and irregular shapes. For example, referring to Figure 1 、 Figures 3 to 7 , the cross-sectional shape of the accommodating cavity 111 is circular. For example, referring to Figures 8 to 12 The cross-sectional shape of the accommodating cavity 111 is circular. Compared to other shapes, such as a rectangle, the circular accommodating cavity 111 has no corners or apex angles, making it easier to completely seal the circular accommodating cavity 111 without leaving any gaps. This makes the circular accommodating cavity 111 more sealed, thereby preventing water from entering and preventing building materials such as concrete from falling into the cavity.

[0086] In some possible embodiments provided by the present invention, a positioning plate 116 is provided at the top of the accommodating cavity 111 along the circumference of the accommodating cavity 111, and the positioning plate 116 extends radially outward along the accommodating cavity 111. The cross-sectional shape of the positioning plate 116 includes at least one of a polygon and an irregular shape.

[0087] For example, refer to Figure 8 In the sixth wiring box 1f, a positioning plate 116 is provided at the top of the accommodating cavity 111 along the circumference of the sixth wiring box 1f. The positioning plate 116 extends radially along the accommodating cavity 111 and has a rectangular cross-sectional shape. The box body 11, which includes the accommodating cavity 111 with a circular cross-section and the positioning plate 116 with a rectangular cross-section, is the second box body 11b. The positioning plates 116, which are distributed along the circumference of the accommodating cavity 111 and contact mounting components such as a switch panel, are rectangular in cross-sectional shape. This allows the rectangular positioning plates 116 to contact and overlap with the rectangular mounting components, thereby enhancing the sealing between the sixth wiring box 1f (the positioning plates 116 of the second box body 11b) and the switch panel.

[0088] For example, reference Figures 9 to 11 The seventh wire box 1g, the eighth wire box 1h and the ninth wire box 1i all include a second box body 11b.

[0089] Exemplarily, the irregular shape is a shape whose cross-sectional shape includes at least one straight line, such as a fan shape.

[0090] The present invention does not specify the cross-sectional shape of the housing cavity 111 of the box body 11 or the cross-sectional shape of the positioning plate 116. Users can configure these shapes based on actual needs. For example, the box body 11 may include a housing cavity 111 with a circular cross-section and a positioning plate 116 with a rectangular cross-section. Another example is that the box body 11 may include a housing cavity 111 with a circular cross-section and a positioning plate 116 with a sector-shaped cross-section.

[0091] Using this technical solution, when wiring is arranged side by side, the straight-line edges of the wiring boxes 1 serve as a positioning mechanism, maintaining the straight-line edges of the side-by-side wiring boxes 1 parallel to each other, thereby ensuring that the side-by-side wiring boxes 1 are parallel to each other. For example, when arranging a piping system 8 comprising a seventh wiring box 1g, an eighth wiring box 1h, and a ninth wiring box 1i side by side, the same edges of the rectangles of the seventh wiring box 1g, the eighth wiring box 1h, and the ninth wiring box 1i are maintained parallel to each other, ensuring that the seventh wiring box 1g, the eighth wiring box 1h, and the ninth wiring box 1i are arranged side by side in parallel.

[0092] In some possible embodiments provided by the present invention, reference is made to Figure 1 and Figure 3As mentioned above, the mounting lug 13 includes a first mounting lug 131 and a second mounting lug 132 that are oppositely arranged along the radial direction Rr of the accommodating cavity 111 , and the radial direction Rr is perpendicular to the axial direction Zr of the accommodating cavity 111 .

[0093] refer to Figure 2 The first mounting lug 131 and the second mounting lug 132 each have a threaded hole 14. A guide portion 141 is provided at one end of the threaded hole 14, near the opening. The inner diameter of the guide portion 141 gradually increases along the bottom toward the opening in a direction Zr1. When installing a screw, the guide portion 141 helps the screw slide into the threaded hole 14, ensuring accurate connection and improving installation efficiency.

[0094] In some possible embodiments, the wiring box 1 further includes a first cover 2, which covers the top opening 112 of the accommodating cavity 111 and is sealed with the top opening 112. Figure 13 and Figure 14 The cross section of the first cover 2 is circular, which is different from the box body 11 (including Figure 1 、 Figures 3 to 11 The first box body 11a and the second box body 11b are shown to be compatible. During the pre-embedding process, the box body 11 is used in conjunction with the first cover body 2. Specifically, the first cover body 2 is placed in the accommodating cavity 111 and radially pressed against the accommodating cavity 111 to seal the first cover body 2 with the top opening 112. This seals the box body 11 with the first cover body 2, providing a good waterproof effect. Furthermore, when pouring concrete or other building materials, the concrete will not fall into the accommodating cavity 111 of the box body 11, facilitating subsequent wiring processes.

[0095] In addition, after pouring concrete and other building materials and before wiring, the first cover 2 must be removed and can be recycled to be used for sealing the box body 11 next time, which reduces resource waste and improves resource recycling rate.

[0096] In some possible embodiments, reference Figure 13 and Figure 14 The first cover 2 is provided with a first sealing portion 21, which is sealed to the inner sidewall 114 of the accommodating cavity 111 along the radial direction Rr of the accommodating cavity 111. That is, the first sealing portion 21 presses against the inner sidewall 114 of the accommodating cavity 111 along the radial direction Rr of the accommodating cavity 111, so that the first sealing portion 21 and the inner sidewall 114 are sealed. That is, the first cover 2 is sealed to the wire box body 11, preventing poured concrete from falling into the accommodating cavity 111 of the wire box body 11 during the pre-embedding process, and having good waterproof performance.

[0097] In this embodiment, the first sealing portion 21 includes any one of a sealing ring, a corrugated spring rubber sleeve or a sealing rubber layer, or the first sealing portion 21 includes a sealing ring and a clamping ring, and the clamping ring presses the sealing ring against the opening 112 so that the inner side wall 114 of the accommodating cavity 111 abuts against the sealing ring.

[0098] In some possible embodiments, reference Figure 13 and Figure 14 The upper end surface 22 of the first cover 2 is provided with a docking portion 23 for docking with a disassembly tool to separate the first cover 2 from the box body 11. Providing the docking portion 23 on the first cover 2 improves the efficiency of separating the first cover 2 from the box body 11, saving work time and cost.

[0099] In this embodiment, the docking portion 23 includes a docking protrusion 231 and a docking groove 232. The docking protrusion 231 is located at the center of the upper end surface 22 of the first cover body 2, and the docking groove 232 is arranged along the circumference of the docking protrusion 231. The docking groove 232 is used to accommodate disassembly and assembly tools. Since the first wire box 1a is used throughout the entire construction cycle, it needs to remain closed for a long time. When replacing or threading the first cover body 2, it is difficult to open and seal the first cover body 2 by hand, and the disassembly and assembly of the first cover body 2 requires the use of a disassembly and assembly tool. In order to facilitate the cooperation between the first cover body 2 and the disassembly and assembly tool, a docking portion 23 is provided on the first cover body 2 in this embodiment.

[0100] In some possible embodiments, reference Figure 13 and Figure 14 The upper end surface 2311 of the docking protrusion 231 does not exceed the upper end surface 22 of the first cover body 2, so that when the first cover body 2 is turned upside down on a horizontal surface such as the ground or a table, the upper end surface 2311 does not touch the ground or the table, and the first cover body 2 is stably and properly placed.

[0101] In some other possible embodiments, the docking portion 23 is an arched rod (not shown in the figure) extending radially along the first cover body 2. The docking tool can separate the first cover body 2 and the box body 11 with the help of the arched rod, or the staff can pull the arched rod with their bare hands to separate the first cover body 2 and the box body 11. In some possible embodiments provided by the present invention, the wire box 1 includes a cover body, which is arranged on the top opening 112 of the accommodating cavity 111 and is sealed with the top opening 112. Along the axial direction of the cover body, a wire outlet tube 333 (not shown in the figure) is provided on the cover body for allowing the cable to pass through. For example, for example, the wire outlet tube 333 is arranged on the first cover body 2 and extends along the axial direction of the first cover body 2 (not shown in the figure). For another example, referring to Figure 31 Combined with Figure 12 The outlet pipe 333 is provided on the third cover body 10 and extends along the axial direction Z10 of the third cover body 10 .

[0102] In some possible embodiments provided by the present invention, the box body 11 and / or the first cover 2 are made of any one of cast iron, alloy material, hard plastic, or resin material, so that the box body 11 and / or the first cover 2 are lightweight, hard, and have good sealing performance. Specifically, the box body 11 is made of cast iron, alloy material, hard plastic, or resin material; or the first cover 2 is made of cast iron, alloy material, hard plastic, or resin material; or the box body 11 and the first cover 2 are made of any one of cast iron, alloy material, hard plastic, or resin material.

[0103] refer to Figure 15 In one embodiment of the present invention, a wire box cover is provided, namely the second cover 3. Figure 15 The wire box cover shown in the figure is called the second cover 3a, and the second cover 3a is used to be closed and connected with the box body 11 of the wire box 1.

[0104] The following text Figure 15 The second cover body 3a shown in FIG. 1 is an example to illustrate the structure of the second cover body 3.

[0105] refer to Figure 15 and Figure 16 , the second cover 3a is provided with an outlet channel 4. Figure 16 The cable outlet channel 4 includes a cable inlet 321 and a cable outlet 311. The cable outlet channel 4 extends through the upper and lower end surfaces 31 and 32 of the second cover 3a along the axial direction Z3 of the second cover 3a. The cable inlet 321 is located on the lower end surface 32, and the cable outlet 311 is located on the upper end surface 31. Cables pass through the cable inlet 321 from the lower end surface 32 of the second cover 3a, pass through the cable outlet channel 4, and exit through the cable outlet 311 on the upper end surface 31 of the second cover 3a. In this embodiment, the cable outlet channel 4 of the second cover 3a is tubular, with the cable inlet 321 and cable outlet 311 being circular.

[0106] refer to Figure 16 (b) The outlet channel 4 includes a flow blocking section 41. Along the direction from the lower end surface 32 to the upper end surface 31 (as shown in the Z31 direction in the figure), the flow blocking section 41 is higher than the cable outlet 311. Figure 16 (b) shows a cross-sectional view, and combined with Figure 17 The height of the cable outlet 311 along the axial direction Z3 of the second cover 3a is H1, and the height of the flow-blocking section 41 along the axial direction Z3 of the second cover 3a is H2, where H2>H1. After wiring is completed and the cable exits through the cable outlet 311, a sealing medium is injected into the outlet channel 4 through the cable outlet 311. This fills the gap between the outlet channel 4 and the cable, sealing the outlet channel 4 and making the second cover 3a a sealed cover.

[0107] In this embodiment, the sealing medium is a liquid or solid. Because the sealing medium is fluid, when the sealing medium is used to fill the gap between the outlet channel 4 and the cable, the flow-blocking section 41, which is higher than the cable outlet 311, can prevent the sealing medium from flowing through the outlet channel 4 and falling into the cable box body 11. On the one hand, the flow-blocking section 41 reduces the amount of sealing medium used, thus saving resources. On the other hand, the flow-blocking section 41 allows the sealing medium to remain in the outlet channel 4 between the cable outlet 311 and the flow-blocking section 41, thereby achieving a good seal of the second cover 3a.

[0108] In some possible embodiments provided by the present invention, reference is made to Figure 16 (b) and Figure 17 The outlet channel 4 also includes a filling section 42. One end of the filling section 42 is provided with a cable outlet 311, and the other end is connected to the flow-blocking section 41. That is, the filling section 42 is located between the cable outlet 311 and the flow-blocking section 41. Along the direction Z31 from the lower end surface 32 to the upper end surface 31, the filling section 42 is lower than the cable outlet 311. The filling section 42 is used to fill the cable outlet channel 4 with a sealing medium after the cable passes through the cable outlet 4. After the cable is routed, the sealing medium is injected into the outlet channel 4 through the cable outlet 311. The sealing medium remains in the filling section 42, sealing the gap between the cable outlet 4 and the cable.

[0109] In some other possible embodiments, refer to Figure 16 (b) and Figure 17 The sealing medium filled in the filling section 42 does not pass through the flow-blocking section 41. The height H2 of the flow-blocking section 41 along the axial direction Z3 of the second cover is higher than the height H1 of the cable outlet 311 along the axial direction Z3 of the second cover, and is higher than the height of the filling section 42 along the axial direction Z3 of the second cover. Therefore, the sealing medium filled in the filling section 42 does not pass through the flow-blocking section 41, so that the sealing medium remains in the filling section 42 to seal the gap between the outlet channel 4 and the cable.

[0110] In some possible embodiments, reference Figure 16 (b) and Figure 17 The outlet channel 4 further includes an ascending section 43 and a descending section 44. The ascending section 43 has a cable outlet 311 at one end and is in communication with the blocking section 41 at the other end. The descending section 44 has a cable inlet 321 at one end and is in communication with the blocking section 41 at the other end. Specifically, the ascending section 43 is disposed between the cable outlet 311 and the blocking section 41. More specifically, the ascending section 43 is disposed between the filler section 42 and the blocking section 41, and ascends in the direction Z31 from the lower end face 32 to the upper end face 31. The descending section 44 is disposed between the cable inlet 321 and the blocking section 41, and descends in the direction Z32 from the upper end face 31 to the lower end face 32.

[0111] That is, in this embodiment, reference Figure 16(b) and Figure 17 The cable outlet 311 , the filling section 42 , the ascending section 43 , the flow-blocking section 41 , the descending section 44 and the cable inlet 321 are connected in sequence to form the outlet passage 4 .

[0112] In some possible embodiments of the present invention, reference Figure 16 and Figure 17 (a), the ascending section 43 and the descending section 44 are arc-shaped, and the flow-blocking section 41 is arch-shaped.

[0113] In some other possible embodiments of the present invention, reference Figure 17 (b) The ascending section 43 and descending section 44 are linear, and the flow-blocking section 41 is door-frame-shaped. The cable outlet 311, the packing section 42, the ascending section 43, the flow-blocking section 41, the descending section 44, and the cable inlet 321 are connected in sequence to form the cable outlet 4, which is in a broken line shape.

[0114] In some possible embodiments of the present invention, reference Figure 18 The upper end surface 31 is provided with an anti-overflow groove 312 at the cable outlet 311 for receiving the sealing medium that overflows from the cable outlet 311. In this embodiment, the sealing medium is liquid or solid. The sealing medium is injected into the outlet channel 4 from the cable outlet 311. After the sealing medium fills the filling section 42 and the rising section 43, it will not pass through the flow-blocking section 41, but will overflow from the cable outlet 311. To improve convenience, aesthetics, and work efficiency, the upper end surface 31 is provided with an anti-overflow groove 312 at the cable outlet 311 for receiving the overflowing sealing medium.

[0115] In some possible embodiments, reference Figure 15 and Figure 16 The second cover body 3a is integrally formed. The integrally formed second cover body 3a has good sealing and waterproof properties.

[0116] In some other possible embodiments, refer to Figures 18 to 21 , along the axial direction Z3 of the second cover body 3a, the second cover body 3a includes an upper cover body 33a (such as Figure 18 and Figure 19 As shown) and the lower cover 34a (as shown Figure 20 and Figure 21 As shown in the figure), the upper cover body 33a and the lower cover body 34a are connected to each other. Exemplarily, the upper cover body 33a and the lower cover body 34a are fixedly connected, for example, by glue or welding (not shown in the figure). Exemplarily, the upper cover body 33a and the lower cover body 34a are detachably connected, for example, the upper cover body 33a and the lower cover body 34a are snap-fitted (as shown in the figure). Figures 18 to 21 As shown), threaded connection is used to facilitate disassembly and assembly of the second cover body 3a to inspect the second cover body 3a.

[0117] In this embodiment, reference Figure 18 and Figure 19 , along the direction Z31 of the lower end surface 32 of the second cover body 3a toward the upper end surface 31, the upper cover body 33a is provided with an upper groove 331. Figure 20 and Figure 21 Along the direction Z32 from the upper end surface 31 of the second cover body 3a toward the lower end surface 32, the lower cover body 34a is provided with a lower groove 341.

[0118] In this embodiment, reference Figures 18 to 21 Combined with Figure 15 and Figure 16 The upper cover 33a is connected to the lower cover 34a so that the upper slot 331 and the lower slot 341 form the outlet channel 4. Specifically, the upper slot 331 includes the filling section 42, the rising section 43, the descending section 44, and the first part of the blocking section 41, and the lower slot 341 includes the filling section 42, the rising section 43, the descending section 44, and the second part of the blocking section 41. The upper slot 331 and the lower slot 341 are connected to each other, that is, the first part and the second part are connected to each other to form a complete filling section 42, the rising section 43, the descending section 44, and the blocking section 41. Among them, one end of the rising section 43 is provided with a cable outlet 311, and the other end is connected to the blocking section 41; one end of the descending section 44 is provided with a cable inlet 321, and the other end is connected to the blocking section 41.

[0119] In some possible embodiments, the upper cover 33a and the lower cover 34a are snap-fitted. Figure 18 and Figure 19 , the upper cover 33a is provided with a snap-fit groove 332; Figure 20 and Figure 21 The lower cover 1 34a is provided with a snap-fitting protrusion 342. The snap-fitting protrusion 342 can be snapped into the snap-fitting groove 332, so that the upper cover 1 33a and the lower cover 1 34a are snap-fitted.

[0120] In some other possible embodiments, refer to Figures 18 to 21 The second cover 3a is provided with a positioning portion 35, the positioning portion 35 includes a positioning protrusion 351 (such as Figure 20 and Figure 21 As shown) and positioning groove 352 (as shown Figure 18 and Figure 19 Reference Figure 20 and Figure 21 The positioning protrusion 351 is provided at the center of the upper end surface of the lower cover 34a along the axial direction Z3. Figure 18 and Figure 19 The positioning groove 352 is provided at the center of the lower end surface of the upper cover body 1 33a along the axial direction Z3. In this embodiment, the upper cover body 1 33a and the lower cover body 1 34a are installed and positioned by the positioning protrusion 351 and the positioning groove 352 to prevent the installation position from shifting.

[0121] In some other possible embodiments, the second cover 3a is connected to the wiring box 1 via the mounting lugs 13 of the box body 11. For example, the second cover 3a is connected to the wiring box 1 via the mounting lugs 13 of the box body 11 by threading, snapping, or gluing. The present invention does not limit the method of connecting the second cover 3a to the wiring box 1 via the mounting lugs 13 of the box body 11.

[0122] For example, the second cover 3a is connected to the wiring box 1 through the mounting lug 13 of the box body 11. Figure 18 and Figure 19 Combined with Figure 1 and Figure 2 The second cover 3a is provided with a snap-fitting groove 36 along its edge for snapping onto the mounting lug 13 of the box body 11 of the wiring box 1. Specifically, when installing the second cover 3a and the wiring box 1, the second cover 3a is pressed into the accommodating cavity 111 of the wiring box body 11. The mounting lug 13 abuts against the lower edge of the notch next to the snap-fitting groove 36 of the second cover 3a. The second cover 3a is then rotated to snap the mounting lug 13 into the snap-fitting groove 36, ensuring a stable and sealed connection between the second cover 3a and the wiring box body 11.

[0123] For example, refer to Figure 31 Combined with Figure 12 The difference between the third cover 10 and the second cover 3 is that the third cover 10 is not provided with an outlet channel 4, but is provided with an outlet tube 333 for the cables to pass through. Figure 12 The third cover 10 is engaged with the ninth wiring box 1i through the mounting lug 13 of the second box body 11b.

[0124] In some other possible embodiments, refer to Figure 15 and Figure 16 The second cover 3a is provided with a second sealing portion 37 along the edge, or refer to Figure 18 and Figure 19 The upper cover 33a of the second cover 3a is provided with a second sealing portion 37 along its edge for sealingly connecting with the wire box body 11. In this embodiment, the second sealing portion 37 includes any one of a sealing ring, a corrugated spring rubber sleeve, or a sealing rubber layer, or the second sealing portion 37 includes a sealing ring and a clamping ring, and the clamping ring presses the sealing ring against the inner wall of the wire box body 11.

[0125] In some other possible embodiments provided by the present invention, the second cover 3 is not limited to the above embodiment. Figures 15 to 21The structure of the second cover body 3a shown is such that users can make second cover bodies 3 with different structures according to their needs, especially second cover bodies 3 with outlet channels 4 of different shapes, but it is necessary to satisfy that the height H2 of the blocking section 41 of the outlet channel 4 along the axial direction Z3 of the second cover body 3 is greater than the height H1 of the cable outlet 311 along the axial direction Z3 of the second cover body 3.

[0126] For example, refer to Figures 22 to 26 , this embodiment provides a second cover 3b. The second cover 3b provided in this embodiment is different from the second cover 3a in the previous embodiment in that the shape of the outlet channel 4 is different. In this embodiment, reference Figure 22 and Figure 23 The outlet channel 4 of the second cover 3b is flat and relatively wide along the radial direction of the second cover 3b. The outlet channel 4 is composed of a plurality of arc segments connected to each other, including a filling segment 42, an ascending segment 43, a descending segment 44, a flow-blocking segment 41 (such as Figure 24 Reference Figure 25 and Figure 26 The cable inlet 321 and the cable outlet 311 are composed of a straight line and an arc, forming a semicircular shape.

[0127] In this embodiment, since the shape of the second cover body 3b outlet channel 4 is different from the shape of the second cover body 3a outlet channel 4, accordingly, refer to Figure 25 and Figure 26 The shapes of the upper slot 331 of the upper cover 33b and the lower slot 341 of the lower cover 34b of the second cover 3b are different from those of the second cover 3b. Figures 18 to 21 The shapes of the upper groove 331 of the upper cover body 33a and the lower groove 341 of the lower cover body 34a of the second cover body 3a are shown.

[0128] For example, reference Figures 27 to 30 , this embodiment provides a second cover body 3c. In this embodiment, the second cover body 3c provided in this embodiment is different from the second cover body 1 3a and the second cover body 2 3b in the above-mentioned embodiment in that the shape of the outlet channel 4 is different. In this embodiment, reference Figure 27 The outlet channel 4 of the second cover body 3c is flat. The outlet channel 4 of the second cover body 3c is narrower in the radial direction than the outlet channel 4 of the second cover body 2 3b in the previous embodiment. In this embodiment, the outlet channel 4 is composed of a plurality of arc segments connected to each other, including a filling segment 42, an ascending segment 43, a descending segment 44, a flow-blocking segment 41 (such as Figure 27 and 28 Reference Figure 29 and Figure 30 The cable inlet 321 and the cable outlet 311 are rectangular.

[0129] In this embodiment, since the shape of the outlet channel 4 of the second cover body 3c is different from the shape of the outlet channel 4 of the second cover body 1 3a and the second cover body 2 3b, accordingly, Figure 29 and Figure 30 The shapes of the upper slot 331 of the upper cover body 33c and the lower slot 341 of the lower cover body 34c are different from those of the lower cover body 34c. Figures 18 to 21 The shapes of the upper slot 331 of the upper cover 33a and the lower slot 341 of the lower cover 34a of the second cover 3a are also different from those of the second cover 3a. Figure 25 and Figure 26 The upper groove 331 of the upper cover 33b and the lower groove 341 of the lower cover 34b of the second cover 3b are shown. Figure 30 The cross-sectional shape of the lower cover body 34c is different from Figure 20 and Figure 21 The cross-sectional shape of the lower cover 34a is shown as well as Figure 26 The cross-sectional shape of the lower cover body 34b is shown.

[0130] In some possible embodiments, mounting holes 313 are provided on the second cover 3 along a radial direction R3 thereof for connecting to a mounting member, such as a switch panel. The mounting holes 313 function similarly to the threaded holes 14 of the mounting lugs 13 described above, both being used to connect the junction box 1 to a mounting member, such as a switch panel.

[0131] In some possible embodiments provided by the present invention, reference is made to Figures 1 to 12 The present invention provides a wire box 1 in any of the above-mentioned embodiments, comprising a box body 11 in any of the above-mentioned embodiments, a wire threading tube 12 and a second cover body 3 in any of the above-mentioned embodiments.

[0132] For ease of description, Figure 3 and Figure 4 The second wiring box 1b is shown as an example to illustrate the second wiring box 1b and the second cover 3a (such as Figure 15 and Figure 16 shown) usage relationship.

[0133] refer to Figure 3 、 Figure 4 、 Figure 15 and Figure 16The second wiring box 1b includes a first box body 11a, a wire guide 12, and the second cover 3a described above. The first box body 11a includes a housing 111 with an open top 112 and a closed bottom 113. Mounting lugs 13 are provided on the inner sidewalls 114 of the housing 111, which are used to connect the first box body 11a to the second cover 3a. The wire guide 12 is provided on the outer sidewalls 115 of the housing 111 and communicates with the housing 111. The first box body 11a and the wire guide 12 are integrally formed.

[0134] In this embodiment, during wiring, the first box body 11a is used in conjunction with the second cover body 3a. Specifically, the second cover body 3a is placed within the accommodating cavity 111, radially pressing against the accommodating cavity 111. This seals the first box body 11a with the second cover body 3a. Furthermore, after wiring is complete, the cable outlet 311, filler section 42, and riser section 43 of the outlet channel 4 of the second cover body 3a are sealed with a sealing medium, ensuring that the second wiring box 1b has excellent sealing and waterproof properties. The second cover body 3a is connected to a mounting component, such as a switch panel (not shown), via the mounting hole 313.

[0135] refer to Figure 32 and Figure 33 The first embodiment of the present invention provides a conduit connector 5. For the convenience of description, Figure 32 and Figure 33 The shown conduit connector 5 is depicted as a first conduit connector 5a.

[0136] refer to Figure 32 and Figure 33 The first conduit connector 5a includes a main body 51, a first elastic wing 521, and a second elastic wing 522. The main body 51 is an open ring shape, including a first free end 511 and a second free end 512. The first free end 511 and the second free end 512 are arranged opposite each other to form an opening. In other words, in a natural state, the first free end 511 and the second free end 512 are separated and do not contact each other, resulting in the main body 51 forming an open ring shape.

[0137] The first elastic wing 521 is provided at the first free end 511 and extends outward from the main body 51, and the second elastic wing 522 is provided at the second free end 512 and extends outward from the main body 51. Figure 32 and Figure 33 As shown, the first elastic wing 521 and the second elastic wing 522 extend outward from the main body 51 along the Xt direction respectively.

[0138] In this embodiment, the first elastic wing 521 and the second elastic wing 522 can be pressed toward each other to be in a locked state. In the locked state, the first free end 511 and the second free end 512 contact each other, so that the main body 51 is in a closed ring shape.

[0139] By adopting the above technical solution, the first elastic wing 521 and the second elastic wing 522 are pressed toward each other to form the conduit connector 5 into a closed ring, so as to seal the conduit connection interface of the first conduit and the second conduit, so that the interface has good sealing and waterproof properties. For example, the first conduit is the conduit 12 on the wire box 1 (such as Figure 1 As shown), the second threading tube is a threading tube 9 (as shown Figure 43 and Figure 44 shown).

[0140] In some possible embodiments of the present invention, reference Figure 32 and Figure 33 The first free end 511 is provided with a closed protrusion 513, and the second free end 512 is provided with a closed recess 514. In the locked state, the closed protrusion 513 cooperates with the closed recess 514 to make the main body 51 a closed ring, so that the first threading tube 12 and the second threading tube 9 have good sealing and waterproof properties at the connection interface.

[0141] refer to Figure 32 In some possible embodiments of the present invention, the first elastic wing 521 and the second elastic wing 522 are each provided with a corresponding threaded hole 54, wherein the first elastic wing 521 is provided with a first threaded hole 541, and the second elastic wing 522 is provided with a second threaded hole 542. During the wiring and assembly process, the first threading tube 12 is inserted into the first end 51a of the main body 51 of the wire conduit connector 5, and the second threading tube 9 is inserted into the second end 51b, so that the two threading tubes abut against each other. Then, the first elastic wing 521 and the second elastic wing 522 are pressed toward each other until the sealing protrusion 513 and the sealing recess 514 contact each other, forming a closed annular shape of the main body 51, thereby locking the first wire conduit connector 5a. In this locked state, screws are inserted through the first threaded hole 541 and the second threaded hole 542 to connect the first elastic wing 521 and the second elastic wing 522 to each other. The first wire conduit connector 5a remains locked, thereby sealing the interface between the first threading tube 12 and the second threading tube 9.

[0142] In this embodiment, with the help of a disassembly tool such as a screwdriver, the screws are unscrewed from the first threaded hole 541 and the second threaded hole 542, so that the first elastic wing 521 and the second elastic wing 522 are separated from each other under their own elastic action, and the main body 51 is an open ring, so that the first conduit connector 5a is switched from the locked state to the natural state.

[0143] refer to Figure 34 and Figure 35 The second embodiment of the present invention provides a conduit connector 5. For the convenience of description, Figure 34 and Figure 35The conduit connector 5 shown is described as a second conduit connector 5b. The second conduit connector 5b provided in the second embodiment differs from the first conduit connector 5a provided in the first embodiment in that the first elastic wing 521 and the second elastic wing 522 are locked in different ways.

[0144] In the second embodiment, the first elastic wing 521 and the second elastic wing 522 of the second conduit connector 5b are each provided with a corresponding pin hole 55. The first elastic wing 521 is provided with a first pin hole 551, and the second elastic wing 522 is provided with a second pin hole 552. The first elastic wing 521 and the second elastic wing 522 are pressed toward each other until the sealing protrusion 513 and the sealing recess 514 contact, forming a closed annular shape of the main body 51, thereby locking the second conduit connector 5b. In this locked state, the first elastic wing 521 and the second elastic wing 522 are connected by a pin 56, maintaining the second conduit connector 5b in a locked state and sealing the interface between the first conduit 12 and the second conduit 9.

[0145] In this embodiment, the pins are removed from the first pin hole 551 and the second pin hole 552 with the help of a disassembly tool such as a pin extractor, so that the first elastic wing 521 and the second elastic wing 522 are separated from each other under their own elastic action, and the main body 51 is an open ring, so that the second conduit connector 5b is switched from the locked state to the natural state.

[0146] refer to Figures 36 to 39 In some possible embodiments of the present invention, a locking portion 53 is provided on the conduit connector 5, and the locking portion 53 includes a locking protrusion 532 and a locking groove 531. The locking protrusion 532 and the locking groove 531 are respectively provided on the second elastic wing 522 and the first elastic wing 521; in the locked state, the locking protrusion 532 is pressed into the locking groove 531 and engages with the locking groove 531.

[0147] For example, refer to Figure 36 and Figure 37 The third embodiment of the present invention provides a conduit connector 5. For the convenience of description, Figure 36 and Figure 37 The conduit connector 5 shown is described as a third conduit connector 5c. The third conduit connector 5c provided in the third embodiment differs from the first conduit connector 5a provided in the first embodiment and the second conduit connector 5b provided in the second embodiment in that the first elastic wing 521 and the second elastic wing 522 have different locking methods.

[0148] In the third embodiment, the third wire tube connector 5c is provided with a first locking portion 53a, wherein the first elastic wing 521 is provided with a first locking groove 531a, and the second elastic wing 522 is provided with a first locking protrusion 532a. The first elastic wing 521 and the second elastic wing 522 are pressed toward each other until the closing protrusion 513 contacts the closing recess 514, and at the same time, the first locking groove 531a is engaged with the first locking protrusion 532a, so that the third wire tube connector 5c is in a locked state, sealing the interface between the first wire tube 12 and the second wire tube 9.

[0149] refer to Figure 36 , a disassembly hole 58 is provided on the first elastic wing 521 near the first locking groove 531a. When the third conduit connector 5c is in a locked state and the first conduit 12 and the second conduit 9 are sealed, it is difficult to restore it to its natural state by hand, and a disassembly tool is required. For example, the disassembly tool is a flat-head screwdriver. Insert the flat-head screwdriver along the extension direction of the disassembly hole 58 (such as Figure 36 As shown, the extending direction of the disassembly hole 58 is the same as the axial direction Zk of the wire tube connector) is placed in the disassembly hole 58, a flat-head screwdriver is brought into contact with the second elastic wing 522, and the flat-head screwdriver is rotated, so that the first elastic wing 521 and the second elastic wing 522 are separated from each other. That is, under the influence of external force, the first elastic wing 521 and the second elastic wing 522 move in opposite directions due to their own elasticity, so that the first elastic wing 521 and the second elastic wing 522 are separated from each other and return to the natural state, so that the interface of the first threading tube 12 and the second threading tube 9 is no longer sealed and connected by the third wire tube connector 5c. In this embodiment, the third wire tube connector 5c can be switched between the locked state and the natural state through the disassembly hole 58 with the help of a disassembly tool such as a flat-head screwdriver, which facilitates the installation, locking and removal of the first threading tube 12 and the second threading tube 9, saves installation and disassembly time, and improves work efficiency.

[0150] For example, refer to Figure 38 and Figure 39 The fourth embodiment of the present invention provides a conduit connector 5. For the convenience of description, Figure 38 and Figure 39 The conduit connector 5 is described as a fourth conduit connector 5d.

[0151] In the fourth embodiment, the fourth wire tube connector 5d is provided with a second locking portion 53b, wherein the first elastic wing 521 is provided with a second locking groove 531b, and the second elastic wing 522 is provided with a second locking protrusion 532b. The first elastic wing 521 and the second elastic wing 522 are pressed toward each other until the closing protrusion 513 contacts the closing recess 514, and at the same time, the second locking groove 531b is engaged with the second locking protrusion 532b, so that the fourth wire tube connector 5d is in a locked state, sealing the interface between the first wire tube 12 and the second wire tube 9.

[0152] In addition, reference Figure 38 In the fourth conduit connector 5d, the first free end 511 of the main body 51 is provided with a closed protrusion and a closed recess in sequence along the conduit connector's axial direction Zk. Correspondingly, the second free end 512 is provided with a closed recess and a closed protrusion in sequence along the conduit connector's axial direction Zk. In the locked state, the closed protrusion and closed recess of the first free end 511 mate with the closed recess and closed protrusion of the second free end 512, respectively, to form the main body 51 into a closed annular shape.

[0153] In this embodiment, the fourth conduit connector 5d can be easily switched to the natural state by using a disassembly tool such as a flat-head screwdriver. Specifically, the flat-head screwdriver is moved along the extension direction of the second locking groove 531b (such as Figure 38 As shown, the extending direction of the second locking groove 531b is the same as the axial direction Zk of the wire pipe connector) and is placed in the second locking groove 531b, so that the two sides of the flat-head screwdriver are respectively in contact with the second locking groove 531b and the second locking protrusion 532b. Specifically, the flat-head screwdriver abuts against an edge of the second locking groove 531b along the extending direction Xt of the first elastic wing 521 away from the main body 51, and the flat-head screwdriver is in contact with the second locking protrusion 532b. Use a flat-head screwdriver to pry the second locking protrusion 532b along the extending direction Xt of the first elastic wing 521 toward the direction close to the main body 51. The first elastic wing 521 and the second elastic wing 522 will separate from each other under their own elastic action, and the fourth wire pipe connector 5d returns to its natural state. The main body 51 is an unclosed ring, so that the interface of the first threading tube 12 and the second threading tube 9 is no longer sealed and connected by the fourth wire pipe connector 5d.

[0154] In some possible embodiments, reference Figures 36 to 39The elastic wings 52 (including the first and second elastic wings 521, 522) are provided with anti-slip ridges 57 at the pressing points to prevent slipping when pressing, thereby improving work efficiency. In this embodiment, the anti-slip ridges 57 are strip-shaped and extend along the axial direction Zk of the conduit connector. Multiple anti-slip ridges 57 are spaced apart. In other possible embodiments, the anti-slip ridges 57 may also have other shapes, such as a grid. The present invention does not limit the shape of the anti-slip ridges, as long as they provide an anti-slip effect when the worker presses the first and second elastic wings 521, 522.

[0155] refer to Figure 40 The fifth embodiment of the present invention provides a conduit connector 5. For the convenience of description, Figure 40 The conduit connector 5 shown is described as a fifth conduit connector 5e. The fifth conduit connector 5e provided in the fifth embodiment differs from the above four embodiments in that the first elastic wing 521 and the second elastic wing 522 are locked in different ways.

[0156] In the fifth embodiment, a first tooth portion 591 is provided between the first free end 511 and the first elastic wing 521, extending outward from the main body 51. A second tooth portion 592 is provided between the second free end 512 and the second elastic wing 522, extending inward from the main body 51. In a natural state, the first tooth portion 591 and the second tooth portion 592 do not contact each other, the first elastic wing 521 and the second elastic wing 522 are separated from each other, and the main body 51 forms an open ring shape. The first elastic wing 521 and the second elastic wing 522 are pressed toward each other until the first tooth portion 591 and the second tooth portion 592 engage with each other. At this point, the first elastic wing 521 and the second elastic wing 522 contact each other, the main body 51 forms a closed ring shape, and the fifth conduit connector 5e is locked. That is, the first tooth portion 591 and the second tooth portion 592 are engaged with each other, and under the elastic action of the first elastic wing 521 and the second elastic wing 522, the first tooth portion 591 and the second tooth portion 592 have a tendency to move in opposite directions along the radial direction of the main body 51, so that the first tooth portion 591 and the second tooth portion 592 are tightened.

[0157] In this embodiment, reference Figure 40 The second elastic wing 522 of the fifth conduit connector 5e is provided with a disassembly hole 58. As previously mentioned, the fifth conduit connector 5e can be switched between a locked state and a neutral state by using a disassembly tool such as a flat-blade screwdriver through the disassembly hole 58. This facilitates the installation, locking, and removal of the first conduit 12 and the second conduit 9, saving installation and removal time and improving work efficiency.

[0158] In summary of the above five embodiments, in the present invention, there is no limitation on the locking method of the first elastic wing 521 and the second elastic wing 522, as long as the main body 51 is an open ring in the natural state and a closed ring in the locked state.

[0159] In the present invention, there is no limitation on the location, length and shape of the closed recess 514 and the closed protrusion 513 respectively provided at the first free end 511 and the second free end 512. It is sufficient to press the first elastic wing 521 and the second elastic wing 522 so that the first free end 511 and the second free end 512 contact each other, so that the main body 51 is in a closed ring shape, thereby sealingly connecting the first threading tube 12 and the second threading tube 9.

[0160] In some possible embodiments provided by the present invention, reference is made to Figure 41 The main body 51 is provided with an annular sealing portion 6 along its inner wall. The first end 61 and the second end 62 of the sealing portion 6 are respectively used to receive the first threading tube 12 and the second threading tube 9. In the locked state, the inner diameter of the sealing portion 6 has an interference fit with the outer diameters of the first threading tube 12 and the second threading tube 9, so that the sealing portion 6 is radially squeezed by the wire tube connector 5 and the first threading tube 12 and the second threading tube 9.

[0161] For example, Figure 36 Take the third conduit connector 5c shown as an example. In this embodiment, the first conduit 12 is inserted into the first end 61 of the sealing portion 6 until it abuts against the middle protrusion 63 of the sealing portion 6, and the second conduit 9 is inserted into the second end 62 until it abuts against the middle protrusion 63 of the sealing portion 6. The first elastic wing 521 and the second elastic wing 522 are pressed to move toward each other until the first locking groove 531a of the first elastic wing 521 is engaged with the first locking protrusion 532a of the second elastic wing 522, and the closed protrusion 513 is in contact with the closed recess 514. The main body 51 is in a closed annular shape, and under the pressure of the main body 51, the inner diameter of the sealing portion 6 and the outer diameter of the first conduit 12 and the second conduit 9 are interference fit, so that the third conduit connector 5c is sealed and connected to the interface of the first conduit 12 and the second conduit 9, achieving a good waterproof effect.

[0162] In some other possible embodiments, refer to Figure 36 、 Figure 38 and Figure 41 , the sealing portion 6 can be independent of the main body 51. That is, the sealing portion 6 is fixedly arranged on the inner side wall of the main body 51, or the sealing portion 6 and the main body 51 are independent of each other, and the sealing portion 6 and the main body 51 are detachable.

[0163] In some possible embodiments, reference Figure 41The sealing portion 6 is a corrugated spring rubber sleeve, which is elastic and can make the inner diameter of the sealing portion 6 interference fit with the outer diameters of the first threading tube 12 and the second threading tube 9.

[0164] In some possible embodiments, the sealing portion 6 is made of elastic material. Figure 41 The sealing portion 6 is made of rubber material so that when the wire tube connector 5 locks the first wire tube 12 and the second wire tube 9, the wire tube connector 5 has an interference fit with the first wire tube 12 and the second wire tube 9.

[0165] In some possible embodiments, the main body 51 is made of a non-metallic material, for example, any one of hard plastic or resin. The conduit connector 5 is provided with a grounding component to prevent accidents such as electric shock and improve personal safety.

[0166] In some possible embodiments, reference Figures 36 to 39 The main body 51 is made of metal and is provided with a conductive portion 7 for grounding the conduit. As previously mentioned, the main body 51 has a first end 51a and a second end 51b. The first end 51a is provided with a first conductive portion 71, and the second end 51b is provided with a second conductive portion 72.

[0167] For example, refer to Figures 32 to 37 The first conductive portion 71 and the second conductive portion 72 are respectively provided on the end surface of the first end 51a and the end surface of the second end 51b of the main body 51. Figure 38 and Figure 39 The first conductive portion 71 and the second conductive portion 72 are respectively disposed on the inner sidewall of the first end 51a and the inner sidewall of the second end 51b of the main body 51. The present invention does not limit the location of the first conductive portion 71 and the second conductive portion 72 on the main body 51. As long as the first conductive portion 71 and the second conductive portion 72 are respectively connected to the outer sidewalls of the first threading tube 12 and the second threading tube 9 to ground the first threading tube 12 and the second threading tube 9, it is sufficient.

[0168] In some possible embodiments of the present invention, reference Figures 33 to 39 , the first conductive portion 71 and the second conductive portion 72 are not on the same straight line along the axial direction Zk of the main body 51 .

[0169] For example, Figure 36Take the third conduit connector 5c shown as an example. The first end 51a of the main body 51 has three first conductive portions 71 spaced apart along the inner sidewall of the first end surface. The second end 51b of the main body 51 has three second conductive portions 72 spaced apart along the inner sidewall of the second end surface. After inserting the first conduit 12 and the second conduit 9 into the first end 51a and the second end 51b, respectively, the third conduit connector 5c is locked. In the locked state, the first conductive portion 71 contacts the outer sidewall of the first conduit 12, and the second conductive portion 72 contacts the outer sidewall of the second conduit 9. These first and second conductive portions 71 and 72 ground the first and second conduits 12 and 9, reducing safety hazards.

[0170] In addition, reference Figure 36 Three first conductive portions 71 are spaced apart along the inner sidewall of the end surface of the first end 51a, and the three first conductive portions 71 are triangular in shape. Three second conductive portions 72 are spaced apart along the inner sidewall of the end surface of the second end 51b, and the three second conductive portions 72 are triangular in shape. The outer walls of the first threading tube 12 and the outer walls of the second threading tube 9 abut against the three first conductive portions 71 and the three second conductive portions 72, respectively. When subjected to external force, the triangular first conductive portions 71 can disperse the force on the first threading tube 12, while the triangular second conductive portions 72 can also disperse the force on the second threading tube 9, preventing deformation of the first threading tube 12 and the second threading tube 9.

[0171] Again, reference Figure 32 and Figure 34 The first conductive part 71 and the second conductive part 72 are respectively arranged at the first end 51a and the second end 51b of the main body 51, and the first conductive part 71 and the second conductive part 72 respectively extend inward of the main body 51 along the radial direction of the main body 51. As mentioned above, when the sealing part 6 and the main body 51 are arranged independently of each other, the first conductive part 71 and the second conductive part 72 have the function of limiting the annular sealing part 6.

[0172] In some other possible embodiments provided by the present invention, the conduit connector 5 is integrally formed. The conduit connector 5 has no connection gap, so that the conduit connector 5 can more tightly connect the interface of the first conduit 12 and the second conduit 9, thereby achieving better waterproof effect.

[0173] In some possible embodiments, reference Figures 42 to 44 The present invention provides a pipeline system 8 including the aforementioned wire pipe connector 5 (such as Figures 32 to 40As shown in FIG. 1 , the conduit connector 5 comprises a main body 51, a first elastic wing 521, and a second elastic wing 522. The main body 51 is an open ring extending along the axial direction Zk. The main body 51 includes a first free end 511 and a second free end 512, which are disposed opposite each other to form an opening. In other words, in a natural state, the first free end 511 and the second free end 512 are separated and do not contact each other, resulting in the main body 51 forming an open ring.

[0174] In this embodiment, reference Figures 32 to 40 Combine Figures 42 to 44 The first elastic wing 521 and the second elastic wing 522 can be pressed toward each other to be in a locked state. In the locked state, the first free end 511 and the second free end 512 contact each other, so that the main body 51 is in a closed ring shape.

[0175] In this embodiment, reference Figures 42 to 44 The conduit connector 5 includes an annular sealing portion 6 disposed within the conduit connector body 51. The sealing portion 6 extends along the axial direction Zk of the body 51. A first conduit 12 (i.e., the conduit 12 of the wiring box 1) extends along the axial direction Zk of the body 51, with one end of the first conduit 12 inserted into one end of the sealing portion 6. A second conduit 9 extends along the axial direction Zk of the body 51, with one end of the second conduit 9 inserted into the other end of the sealing portion 6. In the locked state, the sealing portion 6 forms an interference fit with the first conduit 12 and the second conduit 9, respectively.

[0176] By adopting the above technical solution, the first elastic wing 521 and the second elastic wing 522 of the wire tube connector 5 are pressed to form a closed ring to tighten the first wire tube 12 and the second wire tube 9, so that the sealing part 6 provided in the main body 51 of the wire tube connector 5 is interference fit with the first wire tube 12 and the second wire tube 9, and the interface between the two adjacent wire tubes has good sealing and waterproof properties. On the other hand, the wire tube connector 5 locks the first wire tube 12 and the second wire tube 9 to install the pipeline system 8, and the wire tube connector 5 loosens the first wire tube 12 and the second wire tube 9 to disassemble the pipeline system 8. The installation and disassembly methods of the wire tube connector 5 are simple, which improves the efficiency of installation and maintenance. For the convenience of description, Figure 42 and Figure 44 The pipe system 8 shown illustrates the installation process of the pipe system.

[0177] refer to Figure 42 The piping system 8 includes a fifth wiring box 1e, a first cover 2, a first conduit connector 5a, a second conduit connector 5b, and an annular sealing portion 6 provided in the first conduit connector 5a and the second conduit connector 5b. In the initial stage of wiring, the first cover 2 is used to seal the top opening 112 of the fifth wiring box 1e (as shown in FIG. Figure 7As shown), the accommodating cavity 111 is sealed to prevent it from falling into the building materials during the embedding process.

[0178] During wiring and assembly, refer to Figure 7 and Figure 42 , along the extension direction Zk of the main body 51 of the first conduit connector 5a, one of the first conduit tubes 12 provided on the outer side wall of the fifth wire box 1e is inserted into the first end 51a of the main body 51 of the first conduit connector 5a. More specifically, the first conduit tube 12 is inserted into the first end 61 (as shown in FIG. 5 ) of the sealing portion 6 provided inside the main body 51 of the first conduit connector 5a. Figure 41 Along the extension direction Zk of the main body 51 of the second conduit connector 5b, another first threading tube 12 provided on the outer side wall of the fifth wire box 1e is inserted into the first end 61 of the sealing portion 6 provided inside the main body 51 of the second conduit connector 5b (as shown). Figure 41 shown).

[0179] refer to Figure 43 , along the extension direction Zk of the main body 51 of the first conduit connector 5a, a second conduit 9 is inserted into the second end 51b of the main body 51 of the first conduit connector 5a. More specifically, the second conduit 9 is inserted into the second end 62 (such as the sealing portion 6) provided inside the main body 51 of the first conduit connector 5a. Figure 41 As shown in FIG. 1 ), the first threading tube 12 and the second threading tube 9 are abutted against each other in the sealing portion 6 of the first threading tube connector 5a. Along the extension direction Zk of the main body 51 of the second threading tube connector 5b, another second threading tube 9 is inserted into the second end 62 (as shown in FIG. 1 ) of the sealing portion 6 provided inside the main body 51 of the second threading tube connector 5b. Figure 41 As shown), the other first threading tube 12 and the other second threading tube 9 abut against each other in the sealing portion 6 of the second threading tube connector 5b.

[0180] Continue to refer Figure 43 Combined with Figures 32 to 35The first and second elastic wings 521, 522 of the first and second conduit connectors 5a, 5b are pressed toward each other until the sealing protrusion 513 contacts the sealing recess 514, forming a closed ring shape. This locks the first and second conduit connectors 5a, 5b. In the locked state, screws are inserted through the first and second threaded holes 541, 542 to connect the first and second elastic wings 521, 522. This locks the first conduit connector 5a, sealing the interface between the first and second conduit tubes 12, 9. In the locked state, the first and second elastic wings 521, 522 are connected by pins 56, keeping the second conduit connector 5b locked, sealing the interface between the first and second conduit tubes 12, 9.

[0181] refer to Figure 44 After the pre-buried piping system 8 is completed, the first cover 2 is removed to expose the accommodating cavity 111 of the fifth wiring box 1e when wiring is performed according to the piping system 8. After the wiring is completed, the cables are passed through the cable outlet 311 of the second cover 3a. A sealing agent is then injected into the outlet channel 4 through the cable outlet 311. The sealing agent fills the gap between the outlet channel 4 and the cables, sealing the outlet channel 4 and making the second cover 3a a sealed cover. The second cover 3a is used to seal the accommodating cavity 111 of the fifth wiring box 1e, forming a sealed box body 11 of the fifth wiring box 1e.

[0182] In piping system 8, fifth wiring box 1e is sealed with second cover 3a. Second conduit 9 and first conduit 12 of fifth wiring box 1e are sealed together via first and second conduit connectors 5a and 5b, ensuring piping system 8 is both airtight and waterproof. Furthermore, connecting first and second conduit 12 and 9 via conduit connector 5 simplifies installation and removal, improving installation and maintenance efficiency.

[0183] In some other possible embodiments, for example, the pipeline system 8 includes a first wire box 1a, a first wire pipe connector 5a, and a third cover 10 (eg, Figure 31 When wiring, the cable enters the accommodating cavity 111 of the first box body 11a from the first threading tube 12 of the first wiring box 1a and then passes out through the outlet tube 333 on the third cover body 10.
