Attached Figure Description

[0026] The disclosure of this utility model will become more readily understood by referring to the accompanying drawings. It should be understood that these drawings are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. In the drawings:

[0027] Figure 1 This invention shows a wire harness splitter device according to an embodiment of the present invention, wherein some of the snap-fit ​​seats are connected to snap-fits;

[0028] Figure 2 The diagram illustrates the connection between a wire harness splitter and a corrugated pipe according to an embodiment of the present invention.

[0029] In the accompanying drawings, the same parts use the same reference numerals. The drawings are not drawn to scale. Detailed Implementation

[0030] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0031] One embodiment of this utility model provides a wire harness splitter. For example... Figure 1 and 2As shown, the wire harness splitter 10 includes a first housing 1, a second housing 2, and a latching seat 3. The first housing 1 is shell-shaped and forms the main body of the wire harness splitter 10. The second housing 2 is also shell-shaped and forms the main body of the wire harness splitter 10. The second housing 2 is closedly connected to the first housing 1 to form a main cavity 4 and a splitting cavity 5 communicating with the main cavity 4. The splitting cavity 5 is used to accommodate the corrugated tube 20 for splitting, thus achieving the splitting. The number of splitting cavities 5 is related to the number of wires to be split. This application uses three splitting cavities 5 as an example, but this does not constitute a limitation of this application. That is, the number of splitting cavities 5 can be four, five, or other numbers depending on actual needs. The latching seat 3 is fixed to the outer wall of at least one of the second housing 2 and the first housing 1. That is, the latching seat 3 can be provided only on the first housing 1, only on the second housing 2, or on both the first housing 1 and the second housing 2. The latching seat 3 is used to connect the latch 30. Therefore, the clip seat 3 connects to the clip 30, and the clip 30 then engages with the mounting position on the vehicle body, thus fixing the wiring harness splitter in place and effectively preventing noise caused by the wiring harness splitter striking surrounding parts. Furthermore, fixing the wiring harness splitter also effectively ensures the stability of the splitter and prevents the splitter from falling off. In addition, during the splitter installation process, the corrugated tube 20 for splitting is first positioned in the corresponding position of the splitter cavity 5, and then the first housing 1 and the second housing 2 are closed. It is evident that the separate first housing 1 and second housing 2 facilitate convenient splitter operations.

[0032] In one embodiment, both the first housing 1 and the second housing 2 are constructed as groove-shaped components. Specifically, both the first housing 1 and the second housing 2 include a main cavity groove 8 and a branch cavity groove 9 connected to the main cavity groove 8. The cross-sections of both the main cavity groove 8 and the branch cavity groove 9 are semi-circular. The first housing 1 and the second housing 2 are groove-to-groove, forming a main cavity 4 at the main cavity groove 8 and a branch cavity 5 at the branch cavity groove 9. This configuration of the first housing 1 and the second housing 2 results in a simple structure, ease of fabrication, and convenient docking and installation.

[0033] In one embodiment, a latching seat 3 is fixed on the outer wall of both the second housing 2 and the first housing 1. During the installation of the wiring harness splitter, regardless of the position of the wiring harness splitter, either the second housing 2 or the first housing 1 can be close to the installation position, facilitating the installation of the latch 30 with the vehicle body. Therefore, the above arrangement improves the applicability of the wiring harness splitter. Furthermore, at least two latching seats 3 are arranged on the second housing 2. Simultaneously, at least two latching seats 3 are arranged on the first housing 1. This method of arranging multiple latching seats 3 on the housings (second housing 2 and first housing 1) can improve the connection strength of the wiring harness splitter. Even in a bumpy driving environment, the wiring harness splitter can be stably fixed, avoiding or reducing noise problems caused by the wiring harness splitter falling off.

[0034] One of the latching seats 3 located on the first housing 1 is positioned at the location corresponding to the main cavity 4. Simultaneously, one of the latching seats 3 located on the second housing 2 is positioned at the location corresponding to the main cavity 4. In other words, the latching seats 3 are positioned approximately at the center of the main body of the housing. This arrangement increases the fixing firmness of the latching seats 3, thereby ensuring the secure connection of the wire harness splitter.

[0035] The snap-fit ​​seat 3 includes a base 31, snap-fit ​​strips 32, a blocking plate 33, and a wedge block 34. The base 31 is a square, platform-like structure used for basic connection. In the connection, the base 31 is fixed to the outer wall of the first housing 1 and the second housing 2. The snap-fit ​​strip 32 includes a vertical plate 35 and a horizontal plate 36 fixedly connected to the vertical plate 35. The vertical plate 35 and the horizontal plate 36 are set at an angle, for example, ninety degrees. That is, the snap-fit ​​strip 32 itself is constructed as a right-angled bent plate. Each snap-fit ​​seat 3 includes two snap-fit ​​strips 32. These two snap-fit ​​strips 32 are arranged opposite each other. Specifically, the vertical plate 35 is fixed to the base 31, the two vertical plates 35 are distributed opposite each other at intervals, and the two horizontal plates 36 extend opposite each other and are spaced apart, thus forming a snap-fit ​​groove 37 between the two snap-fit ​​strips 32. The cross-section of the snap-fit ​​groove 37 is T-shaped. During connection, the snap-fit ​​piece 31 of the snap-fit ​​30 can be pulled out into the snap-fit ​​groove 37 and snaps into the snap-fit ​​groove 37 in a direction perpendicular to the mounting surface of the base 31. A stop plate 33 is disposed on the base 31 and located at the end of the snap-fit ​​groove 37 (the end with the stop plate 33). This stop plate 33 restricts the snap-fit ​​piece 31 from continuing to move towards the end of the snap-fit ​​strip 32, providing positioning for the snap-fit ​​piece 31. A wedge block 34 protrudes from the base 31. The wedge block 34 is located between the two snap-fit ​​strips 32 and at the beginning of the snap-fit ​​groove 37 (the end furthest from the end). This wedge block 34 is constructed as a barb-like structure to abut against the snap-fit ​​protrusion (not shown) on the snap-fit ​​piece 31 after the snap-fit ​​30 is in place, preventing the snap-fit ​​30 from falling off from the beginning of the snap-fit ​​groove 37. It can be seen that the stability of the buckle 30 on the buckle seat 3 is limited by the combined action of the snap-fit ​​strip 32, the blocking plate 33 and the wedge block 34.

[0036] The latching seat 3, the first housing 1, and the second housing 2 are all made of one of polyhexamethylene adipamide, caprolactam, polybutylene adipamide, or polypropylene. Furthermore, the first housing 1 and the latching seat 3 disposed thereon are integrally formed, for example, by injection molding. The second housing 2 and the latching seat 3 disposed thereon are also integrally formed, for example, by injection molding. This arrangement uses inexpensive materials and has low manufacturing costs, effectively reducing the manufacturing cost of the wire harness splitter.

[0037] The first housing 1 and the second housing 2 are connected by snap-fit ​​components. Each snap-fit ​​component includes a snap-fit ​​block 61 and a snap-fit ​​ring 62. The snap-fit ​​block 61 is disposed on one of the first housing 1 and the second housing 2, while the snap-fit ​​ring 62 is disposed on the other. During connection, the snap-fit ​​ring 62 engages with the snap-fit ​​block 61. Therefore, the first housing 1 and the second housing 2 can be easily connected together via the snap-fit ​​ring 62 and the snap-fit ​​block 61, facilitating installation operations such as the insertion of the bellows 20.

[0038] Multiple snap-fit ​​components are provided between the first housing 1 and the second housing 2. Part of the snap-fit ​​blocks 61 in the snap-fit ​​components are located on the first housing 1, and part are located on the second housing 2. That is, both snap-fit ​​blocks 61 and snap-fit ​​rings 62 are provided on the first housing 1, and the snap-fit ​​blocks 61 and snap-fit ​​rings 62 on the second housing 2 are matched one-to-one with those on the first housing 1. This arrangement effectively ensures the stability of the connection between the first housing 1 and the second housing 2, and effectively prevents accidental opening of the first housing 1 and the second housing 2.

[0039] In one example, at least three corrugated grooves 7 are provided on the wall of each branch cavity 5. That is, corrugated grooves 7 are provided on the inner walls corresponding to the branch cavities 5 of the first housing 1 and the second housing 2. After the first housing 1 and the second housing 2 are closed, the corrugated grooves 7 form a snap-fit ​​engagement with the bellows 20 inserted into the branch cavity 5, which is used to stably install the bellows 20 in the branch cavity 5, so as to effectively prevent the bellows 20 from falling out.

[0040] This application also relates to wiring harness splitting equipment and vehicles. The wiring harness splitting equipment includes the aforementioned wiring harness splitting device and a clip 30 that engages with the clip holder 3. In this application, no structural modifications are made to the clip 30; any clip adapted to the clip holder 3 of this application can be used. That is, clips from the prior art can be purchased as needed. Figure 1 The figure shows a round hole type clip 30, but the clip 30 can also be a slotted hole type or a keyhole type, etc. The vehicle includes the above-mentioned wiring harness splitter device. It is easy to understand that the clip 30 of the wiring harness splitter device forms a snap-fit ​​with a snap-fit ​​part (not shown in the figure) provided on the vehicle body, for connecting the clip 30 to the vehicle body. The structure of the snap-fit ​​part on the vehicle body matches the structure of the clip 30, and can also be selected by those skilled in the art according to actual needs.

[0041] In the description of this utility model, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "inner" and "outer" refer to the direction toward or away from the geometric center of a specific component, respectively.

[0042] The above are merely the principles and preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several other modifications can be made based on the principles of this utility model, and these modifications should also be considered within the scope of protection of this utility model.
