[0021] While the utility model will be described in full with reference to the drawings containing the preferred embodiments of the utility model, it should be understood before the description that the ordinary skilled in the art can modify the utility model described herein while obtaining the technical effects of the utility model. Therefore, it must be understood that the above description is a broad disclosure to the ordinary skilled in the art, and its content is not limited to the exemplary embodiments described in the utility model.
[0022] In addition, in the following detailed description, many specific details are set forth in order to provide a thorough understanding of the embodiments disclosed herein. It will be apparent, however, to one of ordinary skill in the art that one or more embodiments can be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to avoid obscuring the accompanying drawings.
[0023] According to the general concept of the utility model, a variable-diameter tee manifold for engine wire harness is provided, comprising a manifold body, a first pipe at one end of the manifold body and two second pipes at the other end of the manifold body, wherein the center axes of the first pipe and the two second pipes are in the same plane, and the diameter of the first pipe is greater than that of the second pipe.
[0024] In embodiments according to the utility model, the variable-diameter tee manifold enables the wire harness of the engine to pass through a non-circular space, and such a tee manifold is easy to assemble, has low requirements for installation space, enables more wire harness to be accommodated in limited space, and enables wiring to be more flexible.
[0025] Figure 1 is a mounting schematic diagram of the variable-diameter tee manifold 100 according to an embodiment of the utility model; Figure 2 is a separated schematic diagram of the two half shells 200 of the variable-diameter tee manifold 100 according to an embodiment of the utility model; Figure 3 is a detailed schematic diagram of the mutual buckling of the two half shells 200 of the variable-diameter tee manifold 100 according to an embodiment of the utility model.
[0026] As shown in the figure, the variable-diameter three-way manifold 100 for engine wire harness according to the utility model, comprising manifold body 110, first pipe 120 at one end of manifold body 110 and two second pipes 130 at the other end of manifold body 110, wherein the central axes of first pipe 120 and two second pipes 130 are in the same plane, and the diameter of first pipe 120 is greater than that of second pipe 130. The variable-diameter three-way manifold 100 according to the utility model is configured as above, so that the bellows 400 wrapped outside the engine wire harness of the engine is changed from the original larger diameter circular shape to the flat shape of two smaller diameter circular bellows 400 arranged side by side. When the engine wire harness is routed, the originally narrow space can still be passed through without changing the circuit.
[0027] Among them, the two second pipes 130 are arranged side by side. Such an arrangement makes all the pipes of the variable-diameter three-way manifold 100 extend in one plane without warping, so that the size in the vertical direction of the plane is minimized.
[0028] Among them, the diameters of the two second pipes 130 are not the same. In theory, the diameters of the two second pipes 130 can be the same or different. The function of the variable-diameter three-way manifold 100 is not to reduce the number of wire harnesses but to change the arrangement of the wire harnesses so that one dimension of the cross section is smaller. Therefore, the sum of the cross sections of the two second pipes 130 of the variable-diameter three-way manifold 100 should be greater than or equal to the area of the cross section of the first pipe 120. On the other hand, in order to keep the cross-sectional area as close as possible, the area of the cross section of the first pipe 120 should be close to the area of the cross section of the first pipe 120. In this way, after passing through the variable-diameter three-way manifold 100, the wire harnesses are divided into two bundles, and these two bundles of wire harnesses can still be wrapped with suitable bellows 400.
[0029] In specific practice, the pipe diameter specifications of the larger diameter bellows 400 commonly used for engine wire harnesses on the market are NW10, NW17, NW22, NW26, NW29 and NW37, and the specific size parameters are as follows:
[0030] Inside diameter mm Outside diameter mm Passage area mm2 NW10 10 13 78.5 NW17 16.6 21.2 216.3146 MW22 21.3 25.4 356.1467 NW26 25.8 31.2 522.5274 NW29 29 34.5 660.185 NW37 36.6 42.4 1051.555
[0031] The data of multiple experiments show that, in order to adapt to the above-mentioned specifications of the bellows 400, the best combination of the diameters of the first pipe 120 and the second pipe 130 of the variable-diameter three-way manifold 100 is as follows: when the pipe diameter specification of the first pipe 120 is NW26, the pipe diameter specifications of the two second pipes 130 are NW17 and NW22 respectively; when the pipe diameter specification of the first pipe 120 is NW29, the pipe diameter specifications of the two second pipes 130 are NW22 and NW26 respectively; and when the pipe diameter specification of the first pipe 120 is NW37, the pipe diameter specifications of the two second pipes 130 are NW26 and NW29 respectively.
[0032] The two second tubes 130 are smoothly connected to the first tube 120. This further facilitates wiring in confined spaces.
[0033] like Figure 2 As shown, the reducing tee manifold 100 is formed by two snap-fit half-shells 200. The two half-shells 200 have the same body shape, but are different in that they are respectively provided with snap-fit parts 500 for installation and fixation at the connecting edge of the two half-shells 200. The reducing tee manifold 100 is formed by two snap-fit half-shells 200, which makes it easier to split the engine wiring harness through the reducing tee manifold 100. Specifically, the corrugated pipe 400 is cut off at the part of the engine wiring harness that needs to be split, exposing the wiring harness. The exposed part of the wiring harness is split and placed into one half-shell 200. Then, the other half-shell 200 is used to cover the wiring harness, and the two half-shells 200 are installed in place. The two wiring harnesses leading out from the second pipe 130 are respectively wrapped with corrugated pipes 400 of the corresponding diameter.
[0034] like Figure 2 As shown, the latching element 500 at the connecting edge of the first half-shell 210 of the two half-shells 200 is a socket 211, and the latching element 500 at the connecting edge of the second half-shell 220 of the two half-shells 200 is a plug 221. Those skilled in the art will understand that the latching element 500 is not limited to the form of socket 211 and plug 221, but rather any latching element 500 capable of achieving a locking function.
[0035] like Figure 2 and Figure 3 As shown, there are three snap-fit members 500, which are respectively disposed at the two ends of the connecting edge of the half-shell 200 and at the transition between the first tube 120 and the second tube 130. Those skilled in the art will know that the number of snap-fit members 500 is not limited to three, but can be more or less than three, as long as it ensures a secure snap-fit between the two half-shells 200 without affecting the ease of installation.
[0036] Figure 4 This is a detailed view of the connection between the variable diameter tee manifold 100 and the bellows 400 according to an embodiment of the present invention.
[0037] As shown in the figure, at the end of the first pipe 120 and the second pipe 130, a convex rib 300 is arranged on the inner wall of the first pipe 120 and the second pipe 130, and the height of the convex rib 300 is 2.5mm. The purpose of arranging the convex rib 300 on the inner wall of the first pipe 120 and the second pipe 130 is that when the first pipe 120 and the second pipe 130 are connected with the corresponding corrugated pipe 400, the convex rib 300 can be clamped in the trough of the corrugated pipe 400, so that the connection between the first pipe 120 and the second pipe 130 and the corrugated pipe 400 is more firm.
[0038] The convex rib 300 is arranged at the end of the half shell 200 of the variable-diameter tee manifold 100, and is farther away from the end of the half shell 200 than the buckle 500 arranged at the end of the half shell 200 of the variable-diameter tee manifold 100. Preferably, along the axis direction of the first pipe 120 or the second pipe 130, the convex rib 300 can be arranged close to the buckle 500, and when the convex rib 300 is arranged at this position, due to the locking effect of the buckle 500, the convex rib 300 of the half shell 200 can be facilitated to maintain a circular shape, and the holding force on the corrugated pipe 400 can be improved.
[0039] The half shell 200 is an integral molded part. Generally, the half shell 200 is an integral part made of elastic plastic, which facilitates mass production.
[0040] According to another aspect of the utility model, the variable-diameter tee manifold 100 is also used for wrapping engine wire harness in an engine.
[0041] The variable-diameter tee manifold of the utility model has the advantages that the number of added wires in the engine wire harness can be ensured, the normal wiring in a narrow space is not affected, the assembly of the tee manifold is flexible and fast, the production and design of the engine wire harness are less limited, and the utility model is more efficient and fast.
[0042] Those skilled in the art can understand that the above-described embodiments are exemplary, and those skilled in the art can improve them, and the structures described in various embodiments can be freely combined without structural or principle conflicts, so as to realize more kinds of tee manifolds on the basis of solving the technical problems of the utility model.
[0043] After the preferable embodiments of the present application are described in detail, those skilled in the art can clearly understand that various changes and modifications can be made without departing from the protection scope and spirit of the appended claims, and the present application is not limited to the implementation manners of the exemplary embodiments shown in the specification. It should be noted that the wording "comprising" does not exclude other elements or steps, and the wording "a" or "one" does not exclude multiple. In addition, any element label of the claims should not be understood as limiting the scope of the present application.
