Description

Technical Field

[0001] The utility model relates to the technical field of wire harness fixing devices, in particular to a wire harness fixing device for an electric vehicle. Background Art

[0002] The automotive wiring harness is the main network of the automotive circuit. Without the wiring harness, there would be no automotive circuit. The wiring harness refers to the components that are bundled with the wiring harness to form a circuit connection after the contact terminals made of copper are crimped with wires and cables, and then plastic-pressed with insulators or metal shells.

[0003] At present, a Chinese patent with the existing patent number CN212968966U discloses a wiring harness fixing clamp, which includes a constraint sleeve, a first connecting belt and a second connecting belt, and the constraint sleeve is provided with an axial groove; the first connecting belt is connected to the axial groove, and the first connecting belt is provided with a first mounting hole; the second connecting belt is connected to the axial groove, and the second connecting belt is provided with a second mounting hole; the first connecting belt and the second connecting belt are provided with a first anti-skid rib and a second anti-skid rib, and the first anti-skid groove and the second anti-skid groove are respectively formed between the adjacent two first anti-skid ribs and the adjacent two second anti-skid ribs. Compared with the prior art, the wiring harness fixing clamp provided by the utility model adopts the first anti-skid rib and the second anti-skid rib that can abut against each other to limit the position, effectively offset the lateral driving force of the wiring harness on the connecting belt, prevent the connecting belt from loosening, and is conducive to extending the service life of the wiring harness fixing clamp and improving the practicality of the wiring harness fixing clamp.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems:

[0005] When fixing the wiring harness, if there are many wiring harnesses and multiple wiring harnesses are placed inside the fixing clamp, the cross-sectional diameter of the fixing clamp will be larger, so the wiring harness inside the fixing clamp may move to the connection, resulting in the problem of loose fixation of the wiring harness. For this reason, we propose an electric vehicle wiring harness fixing device. Utility Model Content

[0006] In order to overcome the existing problems, an embodiment of the present application provides an electric vehicle wiring harness fixing device, wherein a limiting pad is provided above a first connecting plate, and a through hole is opened at a position corresponding to the limiting pad on the second connecting plate. When the wiring harness is fixed by a clamp ring, when the second connecting plate moves toward the first connecting plate, the wiring harness inside the clamp ring is limited by the limiting pad to prevent the wiring harness from falling into the first connecting plate and the second connecting plate.

[0007] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0008] A wiring harness fixing device for an electric vehicle, comprising a clamp ring for fixing the wiring harness and a first connecting plate arranged at one end of the clamp ring, a second connecting plate arranged at the other end of the clamp ring, the first connecting plate, the second connecting plate and the clamp ring being an integrally formed structure;

[0009] Among them, when the clamp ring is in a ring state, the first connecting plate and the second connecting plate are in a vertically parallel state, and the first connecting plate is located on the inner side of the second connecting plate and is provided with a limiting pad, and the limiting pad passes through the second connecting plate. When the wiring harness is fixed by the clamp ring, when the second connecting plate moves toward the first connecting plate, the wiring harness inside the clamp ring is limited by the limiting pad to prevent the wiring harness from falling into the first connecting plate and the second connecting plate.

[0010] Through the above technical solution: when the wiring harness is fixed by the clamp ring, when the second connecting plate moves toward the first connecting plate, the wiring harness inside the clamp ring is limited by the limiting pad to prevent the wiring harness from falling into the first connecting plate and the second connecting plate.

[0011] Preferably, the outer wall of the clamp ring is connected with a protective ring, and the protective ring is sleeve-connected to the clamp ring. The protective ring protects the wiring harness placed inside the clamp ring to avoid the problem of wear of the internal wiring harness caused by the clamp ring.

[0012] Preferably, the second connecting plate is provided with a through hole at the intersection of the clamp ring, and the size of the through hole is larger than the size of the limiting pad. When the first connecting plate and the second connecting plate are connected to each other, the limiting pad moves up and down in the through hole inside the second connecting plate, thereby fixing the wiring harness placed inside the clamp ring.

[0013] Preferably, a first connecting hole is formed at one end of the first connecting plate away from the limiting pad, and a second connecting hole is formed at one end of the second connecting plate away from the through hole. The size of the second connecting hole is the same as the cross-sectional diameter of the first connecting hole. When fixing the wiring harness, the wiring harness is placed inside the clamp ring, and then the connecting bolt to be connected is taken out, and the connecting bolt is placed inside the second connecting hole inside the second connecting plate. Then the connecting bolt passes through the first connecting hole inside the first connecting plate, and then is connected to the connecting bolt through a nut, so that the first connecting plate and the second connecting plate are close to each other, and the cross-sectional diameter of the clamp ring is changed, thereby fixing the wiring harness placed inside the clamp ring.

[0014] Through the above technical solution: when the first connecting plate and the second connecting plate are connected to each other, the limiting pad moves up and down in the through hole inside the second connecting plate, thereby fixing the wiring harness placed inside the clamp ring.

[0026] The embodiment of the present application solves the problems in the prior art by providing an electric vehicle wiring harness fixing device, wherein a limiting pad is provided above the first connecting plate, and a through hole is opened on the second connecting plate at a position corresponding to the limiting pad. When the wiring harness is fixed by the clamp ring, when the second connecting plate moves toward the first connecting plate, the wiring harness inside the clamp ring is limited by the limiting pad to prevent the wiring harness from falling into the first connecting plate and the second connecting plate; a protective ring is provided on the outer surface of the clamp ring to protect the wiring harness placed inside the clamp ring to prevent the clamp ring from causing wear to the internal wiring harness.

[0027] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0028] Embodiment 1:

[0029] This embodiment provides a specific structure of an electric vehicle wiring harness fixing device, such as Figure 1-5 As shown, it includes a clamp ring 3 for fixing the wire harness and a first connecting plate 1 arranged at one end of the clamp ring 3, and a second connecting plate 2 is arranged at the other end of the clamp ring 3. The first connecting plate 1, the second connecting plate 2 and the clamp ring 3 are an integrally formed structure;

[0030] Among them, when the clamp ring 3 is in a ring-shaped state, the first connecting plate 1 and the second connecting plate 2 are in a vertically parallel state, and the first connecting plate 1 is located on the inner side of the second connecting plate 2 and is provided with a limiting pad 5, which passes through the second connecting plate 2. When the wiring harness is fixed by the clamp ring 3, when the second connecting plate 2 moves toward the first connecting plate 1, the wiring harness inside the clamp ring 3 is limited by the limiting pad 5 to prevent the wiring harness from falling into the first connecting plate 1 and the second connecting plate 2.

[0031] The outer wall of the clamp ring 3 is connected with a protective ring 4, which is sleeve-connected to the clamp ring 3. The protective ring 4 protects the wiring harness placed inside the clamp ring 3 to prevent the clamp ring 3 from causing wear to the internal wiring harness.

[0032] The second connecting plate 2 is provided with a through hole 6 at the intersection of the clamp ring 3. The size of the through hole 6 is larger than the size of the limiting pad 5. When the first connecting plate 1 and the second connecting plate 2 are connected to each other, the limiting pad 5 moves up and down in the through hole 6 inside the second connecting plate 2, thereby fixing the wiring harness placed inside the clamp ring 3.

[0033] A first connecting hole 7 is formed at one end of the first connecting plate 1 away from the limiting pad 5, and a second connecting hole 8 is formed at one end of the second connecting plate 2 away from the through hole 6. The size of the second connecting hole 8 is the same as the cross-sectional diameter of the first connecting hole 7. When fixing the wiring harness, the wiring harness is placed inside the clamp ring 3, and then the connecting bolt to be connected is taken out, and the connecting bolt is placed inside the second connecting hole 8 inside the second connecting plate 2. Then the connecting bolt passes through the first connecting hole 7 inside the first connecting plate 1, and then is connected to the connecting bolt through a nut, so that the first connecting plate 1 and the second connecting plate 2 are close to each other, and the cross-sectional diameter of the clamp ring 3 is changed, thereby fixing the wiring harness placed inside the clamp ring 3.

[0034] By adopting the above technical solution:

[0035] When the wiring harness is fixed by the clamp ring 3, when the second connecting plate 2 moves toward the first connecting plate 1, the wiring harness inside the clamp ring 3 is limited by the limiting pad 5 to prevent the wiring harness from falling into the first connecting plate 1 and the second connecting plate 2, and the outer wall of the clamp ring 3 is connected to a protective ring 4, which protects the wiring harness placed inside the clamp ring 3 to prevent the clamp ring 3 from causing wear to the internal wiring harness.

[0036] Embodiment 2:

[0037] This embodiment provides a specific structure of an electric vehicle wiring harness fixing device, such as Figure 1-5 As shown, it includes a clamp ring 3 for fixing the wire harness and a first connecting plate 1 arranged at one end of the clamp ring 3, and a second connecting plate 2 is arranged at the other end of the clamp ring 3. The first connecting plate 1, the second connecting plate 2 and the clamp ring 3 are an integrally formed structure;

[0038] Among them, when the clamp ring 3 is in a ring-shaped state, the first connecting plate 1 and the second connecting plate 2 are in a vertically parallel state, and the first connecting plate 1 is located on the inner side of the second connecting plate 2 and is provided with a limiting pad 5, which passes through the second connecting plate 2. When the wiring harness is fixed by the clamp ring 3, when the second connecting plate 2 moves toward the first connecting plate 1, the wiring harness inside the clamp ring 3 is limited by the limiting pad 5 to prevent the wiring harness from falling into the first connecting plate 1 and the second connecting plate 2.

[0039] The second connecting plate 2 is provided with a through hole 6 at the intersection of the clamp ring 3. The size of the through hole 6 is larger than the size of the limiting pad 5. When the first connecting plate 1 and the second connecting plate 2 are connected to each other, the limiting pad 5 moves up and down in the through hole 6 inside the second connecting plate 2, thereby fixing the wiring harness placed inside the clamp ring 3.

[0040] A first connecting hole 7 is formed at one end of the first connecting plate 1 away from the limiting pad 5, and a second connecting hole 8 is formed at one end of the second connecting plate 2 away from the through hole 6. The size of the second connecting hole 8 is the same as the cross-sectional diameter of the first connecting hole 7. When fixing the wiring harness, the wiring harness is placed inside the clamp ring 3, and then the connecting bolt to be connected is taken out, and the connecting bolt is placed inside the second connecting hole 8 inside the second connecting plate 2. Then the connecting bolt passes through the first connecting hole 7 inside the first connecting plate 1, and then is connected to the connecting bolt through a nut, so that the first connecting plate 1 and the second connecting plate 2 are close to each other, and the cross-sectional diameter of the clamp ring 3 is changed, thereby fixing the wiring harness placed inside the clamp ring 3.

[0041] By adopting the above technical solution:

[0042] When the wiring harness is fixed by the clamp ring 3 and the second connecting plate 2 moves toward the first connecting plate 1 , the wiring harness inside the clamp ring 3 is limited by the limiting pad 5 to prevent the wiring harness from falling into the first connecting plate 1 and the second connecting plate 2 .

[0043] Working principle: When fixing the wiring harness, place the wiring harness inside the clamp ring 3, then take out the connecting bolt to be connected, and place the connecting bolt inside the second connecting hole 8 inside the second connecting plate 2. Then the connecting bolt passes through the first connecting hole 7 inside the first connecting plate 1, and then the nut and the connecting bolt are connected to each other, so that the first connecting plate 1 and the second connecting plate 2 are close to each other, changing the cross-sectional diameter of the clamp ring 3, thereby fixing the wiring harness placed inside the clamp ring 3.

[0044] At the same time, when the first connecting plate 1 and the second connecting plate 2 are connected to each other, the limiting pad 5 moves up and down in the through hole 6 inside the second connecting plate 2, so as to fix the wiring harness placed inside the clamp ring 3. After fixation, the protective ring 4 protects the wiring harness placed inside the clamp ring 3 to avoid the problem of wear of the internal wiring harness caused by the clamp ring 3.

[0045] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, 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 from this are still within the scope of protection of the present invention.
