[0032] Combination Figures 1 to 7 As shown, a wiring harness shunt pipe provided by the utility model includes a main line connector 1, a first branch line connector 2 and a clamping assembly 3.

[0033] Combination Figures 1 to 7 As shown, the main line connector 1 includes an annular column 11 and a main line joint 12, and the main line joint 12 is integrally formed on the side wall of the annular column 11, and the main line passes through the main line joint 12 to enter the main line connector 1; the first branch line connector 2 includes a cylindrical barrel 21 and a first branch line joint 22, and the cylindrical barrel 21 is integrally formed with the first branch line joint 22, and the branch line passes through the first branch line joint 22 to enter the first branch line connector 2; the annular column 11 and the cylindrical barrel 21 have the same diameter, and the two ends of the annular column 11 are respectively rotatably connected to one of the cylindrical barrels 21 through a clamping assembly 3.

[0034] In this embodiment, the main line connector 1 and the first branch line connector 2 are rotationally connected by the snap-on assembly 3, so that the main line joint 12 and the first branch line joint 22 can be flexibly rotated, thereby increasing the applicability of the diversion pipe in the diversion direction. The closed body formed by the rotational connection of the annular column 11 and the cylindrical barrel 21 realizes the protection of the diversion position, and the main line and the branch line are interconnected in the closed body.

[0035] In some embodiments, in combination Figures 1 to 3 As shown, the snap-fit ​​assembly 3 includes a snap-fit ​​convex structure 31 and a snap-fit ​​concave structure 32, the snap-fit ​​convex structure 31 is an annular protrusion with the same inner diameter as the cylindrical barrel 21, one end of the snap-fit ​​convex structure 31 is fixedly connected to the cylindrical barrel 21, and the outer wall of the other end of the snap-fit ​​convex structure 31 is provided with a snap-fit ​​protrusion, the snap-fit ​​concave structure 32 is an annular protrusion with the same outer diameter as the annular column 11, one end of the snap-fit ​​concave structure 32 is fixedly connected to the annular column 11, and the outer inner wall of the other end of the snap-fit ​​concave structure 32 is provided with a snap-fit ​​protrusion, and the snap-fit ​​convex structure 31 and the snap-fit ​​concave structure 32 are rotatably snap-fitted.

[0036] In this embodiment, the function of the snap-in assembly 3 is to realize the rotational connection between adjacent components. The snap-in assembly 3 is snapped together by the snap-in protrusions on the snap-in protrusion structure 31 and the snap-in concave structure 32. After the snap-in is connected, the separation is avoided while retaining the ability to rotate relative to each other.

[0037] In some embodiments, in combination Figure 2 As shown, the wiring harness diverter pipe also includes a second branch line connector 4, which is rotatably clamped between the main line connector 1 and the first branch line connector 2 through a clamping assembly 3. The second branch line connector 4 is added to allow the main line to branch out more branches. When the second branch line connector 4 is not added, only two branches can be diverted. The second branch line connector 4 is assembled between the main line connector 1 and the first branch line connector 2 by a rotating clamping method, which retains the flexibility of the assembly angle, so that the wiring harness diverter pipe can adapt to a variety of diversion angles and can adapt to more diversion quantities.

[0038] In some embodiments, in combination Figures 5 to 7 As shown, one end of the second branch line connector 4 close to the main line connector 1 is fixedly connected to the snap-in convex structure 31, and one end of the second branch line connector 4 close to the first branch line connector 2 is fixedly connected to the snap-in concave structure 32. Due to the different snap-in structures of the main line connector 1 and the first branch line connector 2, different structures are required at both ends of the second branch line connector 4 to snap-in the main line connector 1 and the first branch line connector 2.

[0039] In some embodiments, in combination Figure 5 , 6As shown, the second branch line connector 4 includes a second branch line joint 41 and a uniform connection tube 42. The second branch line joints 41 are evenly distributed around the uniform connection tube 42, and the second branch line joints 41 are fixedly connected to the side wall of the uniform connection tube 42. The number of the second branch line joints 41 is at least 1.

[0040] In this embodiment, the second branch connector 4 includes multiple forms, and the number of second branch connectors 41 on each form of the second branch connector 4 is different. Although the second branch connector 4 connected to only one second branch connector 41 can adapt to all situations, the volume of the wiring harness diverter tube will eventually expand rapidly. The use of a second branch connector 4 connected to multiple second branch connectors 41 can effectively reduce the volume expansion rate of the harness diverter tube.

[0041] In some embodiments, in combination Figure 7 As shown, the number of the second branch line connectors 41 is 2, and two second branch line connectors 41 are fixedly connected to the side wall of the uniform connecting tube 42, and the two second branch line connectors 41 are distributed at right angles.

[0042] In this embodiment, the angle between the second branch line joints 41 on the uniform connecting tube 42 is designed to be a specific value, which can reduce the limitation on the diversion angle due to the inability to adjust the angle between the second branch line joints 41 on the uniform connecting tube 42. The specific value here can also be other numerical values.

[0043] In some embodiments, in combination Figure 1 As shown, the wiring harness shunt pipe also includes a fixing component 5, and the fixing component 5 includes a bolt and a nut. The bolt passes through the main line connector 1 and the first branch line connector 2 and is threadedly connected to the nut. Although the rotationally clamped main line connector 1 and the first branch line connector 2 improve the flexibility of the angle, it also causes the angle between the main line and the branch line to be unable to be fixed. After adjusting the angle between the main line and the branch line, the fixing component 5 can be used to fix the relative position of the main line connector 1 and the first branch line connector 2.

[0044] In some embodiments, in combination Figure 1 , 4 As shown, the first branch line connector 2 also includes a mounting groove 23, and the mounting groove 23 is opened at the center of the outer bottom surface of the cylindrical barrel 21. The fixing component 5 is assembled in the mounting groove 23. After the mounting groove 23 is designed, the bolts and nuts in the fixing component 5 will sink into the mounting groove 23, which ensures the stability of the maximum outer contour of the wiring harness shunt pipe, and at the same time can reduce the contact between the outside world and the fixing component 5, thereby reducing the occurrence of loosening of the fixing component 5.

[0045] In some embodiments, in combination Figure 1As shown, the wiring harness shunt pipe also includes a plastic cylinder 6, and the number of the plastic cylinder 6 is the sum of the main line connector 12 and the first branch line connector 22. Each of the main line connector 12 and the first branch line connector 22 is fixedly sleeved with a plastic cylinder 6, and each main line and branch line passes through a plastic cylinder 6. The function of the plastic cylinder 6 is to change the shape of the plastic cylinder 6 by pressure after the main line and the branch line are connected, so that the plastic cylinder 6 is in close contact with the main line and the branch line to provide a fixing effect.

[0046] In some embodiments, in combination Figure 1 As shown, the main line connector 1 and the first branch line connector 2 are both made of engineering plastics. The engineering plastics have high strength to protect the diversion position. At the same time, the engineering plastics have high insulation and corrosion resistance and can effectively provide isolation.

[0047] Working process: Both ends of the first branch line connector 2 are rotatably connected to a main line connector 1 through a clamping assembly 3, and the main line connector 1 and the first branch line connector 2 are rotated to a working angle. After the connection is completed, the annular column 11 and the cylindrical barrel 21 form a sealed body, and the main line passes through the main line joint 12 to enter the sealed body, and the branch line passes through the first branch line joint 22 to enter the sealed body. The main line and the branch line in the sealed body are connected to each other.

[0048] When the number of branches exceeds two, a second branch line connector 4 is added between the main line connector 1 and the first branch line connector 2. The second branch line connector 4 is rotatably connected between the main line connector 1 and the first branch line connector 2 through the snap-on assembly 3. All three can rotate freely. The extra branch lines can pass through the second branch line joint 41 into the sealing body and be interconnected with the main line.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
