[0002] Cable ties, as the name implies, are straps for tying things. They are designed with a stop function, so they can only be tied tighter and tighter. They are often used for cables of electromechanical products, computers, electronic products, automotive wiring harnesses, etc. After the cable ties are tied to the wiring harness, they are set on the mounting base through fixing columns to ensure that the wiring harness does not shake. At present, each cable tie is fixed with a separate fixing column. When multiple wiring harnesses need to be arranged on the same path, only additional fixing columns can be added to fix each wiring harness separately. In many cases, the space near the mounting base is very limited and a sufficient number of fixing columns cannot be set. Therefore, in the prior art, a new solution is urgently needed to solve the above problems. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] A wire harness fixing device, used to fix the wire harness on a mounting base 100, such as Figure 1-Figure 3 As shown, including:

[0028] A fixing plate 1 is arranged on the mounting base 100;

[0029] A fixed column 2, vertically arranged on the fixed plate 1;

[0030] At least two fixing parts 4, each fixing part 4 is provided with a through hole 42 and is sleeved on the fixing column 2;

[0031] At least one sleeve 5 is sleeved on the fixing column 2 and located between two adjacent fixing portions 4. The outer diameter of the sleeve 5 is larger than the inner diameter of the through hole 42.

[0032] At least two cable ties 3 are used to bundle the wire harness. The cable ties 3 include a cable tie body 31 and a bayonet end 32 connected to each other. The bayonet ends 32 are fixedly connected to the fixing parts 4 respectively.

[0033] The sleeve 5 is sleeved on the fixing column 2, which can make two adjacent fixing parts 4 have a gap in the extension direction of the fixing column 2 to prevent the wire harness fixed by the cable tie 3 from interfering with each other. After the cable tie 3 is wrapped around the wire harness, the cable tie body 31 is inserted into the bayonet end 32 and gradually tightened to complete the bundling of the wire harness. When multiple wire harnesses need to be fixed separately, multiple cable ties 3 need to be used at the same time. The fixing column 12 on the fixing plate 1 of this solution can be sleeved with multiple fixing parts 4 at the same time to fix multiple cable ties 3, thereby fixing multiple wire harnesses. In order to prevent interference between wire harnesses, a sleeve 5 is set between the fixing parts, so that the fixing parts 4 are spaced in the extension direction of the fixing column 2 to ensure the correct fixation of the wire harness.

[0034] In some embodiments, the fixing column 2 is provided with threads, and the fixing portion 4 and the sleeve 5 are screwed to the fixing column 2. The fixing portion 4 and the sleeve 5 connected by threads are not easy to fall off.

[0035] Furthermore, a nut 6 is provided above the fixing portion 4 which is farthest from the fixing plate 1. Figure 3 As shown, the nut 6 disposed on the fixing column 2 can further prevent the fixing portion 4 from falling off and press the fixing portion 4 and the sleeve 5 to prevent them from shaking.

[0036] In other embodiments, Figure 2 As shown, a clamping portion is provided on the fixing column 2 , a clamping claw 421 is provided in the through hole 42 , and the fixing portion 4 is clamped with the clamping portion through the clamping claw 421 and fixed on the fixing column 2 .

[0037] In this solution, a snap-on connection is used instead of a screw connection. The advantage of the snap-on connection is that the installation is faster and the anti-retraction function can be achieved without other devices.

[0038] In some embodiments, the fixing portion 4 is integrally formed with the cable tie 3. The integrally formed design is faster to install, more stable in connection, and can effectively reduce costs.

[0039] In some embodiments, the fixing plate 1 is provided with a plurality of mounting holes 11, which are fixed to the mounting base 100 by screws or rivets. Figure 1 As shown, screws are used to pass through the mounting holes 11 to fix the fixing plate 1 on the mounting base 100, which is convenient, fast and easy to disassemble.

[0040] In some embodiments, one or more sleeves 5 are provided between two adjacent fixing portions 4. In actual use environments, different wire harness cross-sectional areas vary greatly, and the gaps between wire harnesses are also different. If sleeves 5 with matching lengths are provided according to different distances, multiple molds need to be provided, and the processing cost is very high. The sleeves 5 provided in this embodiment are of uniform small size, and one or more sleeves 5 can be selected or superimposed as needed to ensure the spacing between the fixing portions 4.

[0041] In some embodiments, a notch 41 for shock absorption is axially provided on the side wall of the through hole 42. Some wiring harnesses are heavy and will shake repeatedly in an installation environment such as a car, which may loosen the fixing column 2. Therefore, a notch 41 is provided on the fixing portion 4 to play a buffering role and prevent the fixing column 2 from receiving more impact.

[0042] The utility model also provides a vehicle-mounted wire harness fixing structure, including a car sheet metal 7 and a wire harness fixing device as described above, wherein the fixing column 2 passes through the car sheet metal 7, and the two end faces of the car sheet metal 7 are provided with the fixing plate 1. When the mounting base 100 is the car sheet metal 7 and both ends of the car sheet metal 7 need to fix the wire harness, a fixing column 2 can be selected to pass through the car sheet metal 7, and the wire harness fixing device is provided on both sides of the car sheet metal 7, so that the wire harness can be fixed on both sides of the car sheet metal 7.

[0043] Furthermore, through holes or threaded holes for connecting with studs are provided on the fixing plate 1 and the automobile sheet metal 7. The studs pass through the through holes or threaded holes of the fixing plate 1 and the automobile sheet metal 7 to fix the fixing plate 1 on the automobile sheet metal 7, which is convenient for installation and removal.

[0044] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
