They are only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0030] like Figure 1As shown, the wire harness device of this utility model is applied to equipment that requires wire harness fixing. It includes a wire harness fixing component 1 and a buckle 3 detachably connected to the wire harness fixing component 1. The wire harness fixing component 1 is used to carry the wire harness. The wire harness fixing component 1 can be connected to the buckle 3 at different angles. The buckle 3 is configured to connect with the snap-fit ​​hole opened on the equipment to fix the wire harness fixing component 1 on the equipment.

[0031] For example, such as Figure 1 As shown, the wire harness fixing component 1 includes a support portion 11 for supporting the wire harness, a fixing pin 2 connected to the support portion 11, and a fixing hole 32 provided on the buckle 3, which is combined with... Figure 2 The fixing pin 2 can be inserted into the fixing hole 32 and can change the connection angle and position of the bearing part 11 relative to the buckle 3.

[0032] When connecting the wire harness fixing part 1 and the buckle 3, the position of the bearing part 11 relative to the buckle 3 can be adjusted according to the position of the surrounding parts and the needs of wire harness installation. Then, the fixing pin 2 is inserted into the fixing hole 32, which can avoid various parts of the equipment and prevent the wire harness route and the entire wire harness device from interfering with various parts around the equipment.

[0033] For example, combined Figure 1 and Figure 2 The support portion 11 includes a first bearing surface 12 and a second bearing surface 13 opposite to the first bearing surface 12. The first bearing surface 12 is used to contact the wire harness, and the second bearing surface 13 faces the buckle 3. The fixing pin 2 is connected to the second bearing surface 13. The wire harness can be fixed to the support portion 11 by cable ties.

[0034] Understandably, the shape of the support portion 11 is not limited and can be adjusted to adapt to different wire harnesses as needed. For example, the shape of the support portion 11 can be, but is not limited to, a flat plate (such as...). Figure 3 As shown), a flat L-shaped plate (such as...) Figure 4 As shown), an L-shaped plate bent towards buckle 3 (such as...). Figure 5 (as shown), wire harness rings, etc.

[0035] For example, such as Figure 3 As shown, in order to strengthen the fixing of the wire harness, the end of the bearing part 11 is provided with a flange 14 extending towards the second bearing surface 13. The flange 14 is used to snap the cable tie fixing the wire harness and prevent the cable tie from falling off from the end of the bearing part 11.

[0036] In an example scheme, such as Figure 4 As shown, a notch 16 is provided at the end of the bearing portion 11, and the notch 16 penetrates the first bearing surface 12 and the second bearing surface 13. The cable tie of the wire harness can bypass the notch 16 and be fixed to the bearing portion 11, so that the wire harness is more firmly fixed to the first bearing surface 12. In another example, as... Figure 4As shown, a cable tie hole 15 is provided on the support part 11. The cable tie hole 15 passes through the first support surface 12 and the second support surface 13. The cable tie can pass through the cable tie hole 15 to fix the wire harness on the support part 11.

[0037] Furthermore, cable tie holes 15 are provided in the middle of the support portion 11 to secure the wire harness in the middle of the support portion 11.

[0038] For example, in order to better support the wire harness, such as Figure 4 As shown, the first bearing surface 12 is concave, and the curvature of the concave surface is adapted to the curvature of the wire harness, so that the wire harness can fit better into the first bearing surface 12.

[0039] exist Figure 5 In one embodiment, in order to reinforce the bearing portion 11, a reinforcing rib 17 may be provided at the bend of the L-shaped plate that bends toward the buckle 3.

[0040] For example, such as Figure 1 As shown, the cross-section of the fixing pin 2 can be a regular polygon, and the cross-section of the fixing hole 32 is also set as a corresponding regular polygon, so that the fixing pin 2 can be inserted into the fixing hole 32 at different angles, thereby enabling the wire harness fixing member 1 to be connected to the buckle 3 at different angles.

[0041] In one example, the cross-section of the fixing pin 2 is a regular octagon, and the cross-section of the fixing hole 32 is correspondingly set to a regular octagon. Any two adjacent directions of the regular octagon are at 45° to each other. Therefore, the fixing pin 2 can be fitted with the hole wall of the fixing hole 32 by rotating at multiple angles such as 45°, 90°, 135°, and 180°.

[0042] For example, combined Figure 1 and Figure 3 To ensure the fixing pin 2 is more securely fixed within the fixing hole 32, the fixing pin 2 includes a connecting portion 21. A connecting protrusion 23 protrudes from the outer periphery of the connecting portion 21. The connecting portion 21 is used for fixed connection with the fixing hole 32 of the buckle 3. Figure 6 The wall of the fixing hole 32 is provided with a corresponding hook groove 34. When the fixing pin 2 is inserted into the fixing hole 32, the connecting protrusion 23 of the fixing pin 2 can be engaged in the hook groove 34 of the buckle 3, thereby fixing the wire harness fixing member 1 to the buckle 3.

[0043] In one example, the connecting protrusion 23 of the fixing pin 2 is set as an elastic element, which can be pulled out of the fixing hole 32 by external force, and then inserted back into the fixing hole 32 at different angles as needed.

[0044] In an example scheme, such as Figure 3As shown, the connecting protrusion 23 is a wedge-shaped barb and is inclined toward the second bearing surface 13. The inclined setting of the wedge-shaped barb makes it easier for the connecting protrusion 23 to enter the fixing hole 32 and be inclinedly engaged in the hook groove 34, which can increase the resistance of pulling out the wire harness fixing member 1, thereby making the fixing pin 2 more firmly engaged in the fixing hole 32.

[0045] Understandably, the connecting protrusion 23 can also be other shapes, such as, but not limited to, square, round or other irregular shapes, as long as it can be inserted into the fixing hole 32 and snapped into the corresponding hook groove 34.

[0046] In an example scheme, such as Figure 6 As shown, the fixing hole 32 has multiple rows of hook grooves 34 inside its wall, corresponding to multiple rows of connecting protrusions 23. The multiple rows of connecting protrusions 23 are distributed along the axial direction of the fixing pin 2, and each row of hook grooves 34 is arranged around the circumference of the hole wall to facilitate the engagement of the connecting protrusions 23. This arrangement of the hook grooves 34 also facilitates the manufacturing and processing of the fixing pin 2. In other embodiments, the hook grooves 34 may also be arranged in a one-to-one correspondence with the connecting protrusions 23.

[0047] Furthermore, the connecting portion 21 of the fixing pin 2 extends towards the second bearing surface 13 with a positioning portion 22. The positioning portion 22 is a frustum of a pyramid with the same cross-sectional shape as the connecting portion 21, such as... Figure 3 As shown, the wider base of the frustum is mounted on the second bearing surface 13, and the narrower base of the frustum is connected to the connecting part 21. Since the cross-sectional shape of the frustum of the positioning part 22 is the same as the cross-sectional shape of the connecting part 21, the side conversion angles of the positioning part 22 and the connecting part 21 are kept consistent.

[0048] Correspondingly, the buckle 3 also includes a positioning hole 33, which is used to accommodate the positioning part 22 of the fixing pin 2. The positioning hole 33 communicates with the fixing hole 32. The shape of the hole wall of the positioning hole 33 matches the truncated pyramid shape of the positioning part 22. The positioning part 22 can be embedded in the positioning hole 33, and the outer periphery of the positioning part 22 fits against the hole wall of the positioning hole 33, thereby further positioning the connecting part 21 of the fixing pin 2 and preventing the connecting part 21 from rotating after fixing.

[0049] To ensure that the retaining pin 2 is smoothly inserted into the retaining hole 32, such as Figure 3 As shown, the outer periphery of the end of the connecting part 21 is provided with a chamfer 24, which is inclined toward the central axis of the connecting part 21 to facilitate the insertion of the connecting part 21 into the fixing hole 32.

[0050] like Figure 1 As shown, the buckle 3 includes a mounting base 4 and a snap-fit ​​portion 5. The positioning hole 33 and the fixing hole 32 of the buckle 3 penetrate the mounting base 4 and the snap-fit ​​portion 5. The mounting base 4 includes a skirt 41 extending towards the snap-fit ​​portion 5. Figure 2When the fixing pin 2 is connected to the buckle 3, one end of the arc surface of the skirt 41 of the mounting base 4 abuts against the second bearing surface 13 of the fixing pin 2, so that the wire harness fixing piece 1 can be easily removed from the buckle 3 through the edge of the skirt 41, so as to facilitate the replacement of the wire harness fixing piece 1.

[0051] When the wire harness device is installed on the equipment, the snap-fit ​​part 5 snaps into the snap-fit ​​hole on the equipment, and the other end of the flat surface of the skirt 41 abuts against the edge of the opening of the snap-fit ​​hole of the equipment to fit with the equipment. Thus, the buckle 3 can be removed from the equipment through the other end of the flat surface of the skirt 41 to facilitate the replacement of the buckle 3.

[0052] The wire harness device of this utility model unifies the type of buckle 3 and the type of fixing pin 2 that matches the buckle 3 by detachably connecting the wire harness fixing member 1 and the buckle 3. The fixing pin 2 is located on the bearing part 11 of the wire harness fixing member 1, so the wire harness device of this utility model can be universal. It is only necessary to match the bearing part 11 of different shapes according to the requirements of different wire harness directions, such as flat plate, flat L-shaped plate, bent L-shaped plate, wire harness ring, etc., so that the installation can be completed conveniently and quickly. Moreover, by changing the angle of connection between the fixing pin 2 and the buckle 3, the bearing part 11 of the same shape can match the wire harness direction at multiple angles.

[0053] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
