Description

Technical Field

[0001] The utility model relates to the technical field of wire harness buckles, in particular to an anti-loosening wire harness buckle component used in an ABS sensor. Background Art

[0002] In automotive electronic systems, ABS anti-lock brake sensors are key components. The stability of their signal transmission directly affects driving safety. Reliable fixation of the sensor harness is one of the important factors to ensure that signal transmission is not interfered with. However, traditional harness fixing structures mostly use cable ties, clamps or bolt fastening structures. During vehicle driving, due to factors such as vibration, impact or assembly stress, traditional harness fixing structures are prone to loosening and wear, which in turn leads to abnormal signal transmission or sensor failure. Utility Model Content

[0003] In order to overcome the shortcomings of the background technology, the technical solution adopted by the present invention is: an anti-loosening wire harness buckle assembly applied to an ABS sensor, comprising a protective cover sleeved on the wire harness, and a buckle body for clamping the protective cover, the protective cover is provided with a circular groove for clamping the buckle body, the buckle body comprises an integrally formed main buckle part, an elastic part and a secondary buckle part, the main buckle part is provided with a side clamping part for fixing, and one end of the main buckle part is connected to the secondary buckle part through the elastic part, and the other end is provided with a clamping slot, the secondary buckle part is provided with a clamping strip adapted to the clamping slot, and the main buckle part and the secondary buckle part are combined to form a first mounting groove for clamping the protective cover.

[0004] Using the above technical solution, the protective cover is a hollow rotating body made of rubber material, which is interference-connected with the wiring harness through a press. The protective cover is connected to the buckle body as an adapter, and the buckle body is fixed to the frame through the side clamping part, thereby achieving the fixation of the wiring harness. Since the buckle body is formed by an integrated injection molding process, the bending deformation of the elastic part makes the clamping strip of the auxiliary buckle part and the clamping slot of the main buckle part rotate closely together, avoiding the loosening of the wiring harness due to vehicle vibration or external force impact. No additional fasteners or auxiliary accessories are required, which simplifies the assembly process and improves installation efficiency. At the same time, it ensures the stability of ABS sensor signal transmission and further enhances driving safety.

[0005] The present invention is further configured such that the main buckle portion is provided with a first vertical portion, the auxiliary buckle portion is provided with a second vertical portion for clamping the first vertical portion, and the first vertical portion is connected to the second vertical portion through an elastic portion.

[0006] Furthermore, the first vertical portion is provided with a first fixed arm and a first clamping arm, the second vertical portion is provided with a second clamping arm, the elastic portion is connected between the first fixed arm and the second clamping arm, and when the secondary clamping portion and the main clamping portion are closed, the first clamping arm abuts against the second clamping arm.

[0007] By adopting the above technical solution, when the main buckle part and the auxiliary buckle part are closed, a positioning structure is formed by the first vertical part and the second vertical part to ensure that the clamping strip of the auxiliary buckle part and the clamping groove of the main buckle part form a clamping structure, thereby preventing the buckle body from naturally disengaging due to vehicle vibration or external force impact.

[0008] The present invention is further configured such that the auxiliary buckle portion is provided with a first rectangular portion adapted to the card slot, the card strip is provided at one end of the first rectangular portion, and a limiting portion engaged with the card strip is provided in the card slot.

[0009] Furthermore, the clamping strip is provided with a clamping hook in the direction toward the first installation slot, and the limiting portion is provided with a chamfered surface and a locking surface corresponding to the clamping hook.

[0010] By adopting the above technical solution, when the auxiliary buckle part rotates through the elastic part and clamps the main buckle part, the chamfered surface serves as a guide surface, so that the hook is clamped into the locking surface from the chamfered surface along the outer contour of the limiting part and completes the buckling action. The overall structure is simple and easy to install.

[0011] The present invention is further configured such that the main buckle portion is provided with extension portions on both sides of the clamping slot, and the height of the extension portions is the same as the height of the first rectangular portion.

[0012] By adopting the above technical solution, when the first rectangular part of the auxiliary buckle part is inserted into the first installation groove, the first rectangular part is embedded in the slot. Since the height of the extension part is the same as the height of the first rectangular part, the outer surface of the first rectangular part is coplanar with the back surface of the auxiliary buckle part, making the outer contour of the buckle body regular.

[0013] The present invention is further configured such that the main buckle portion is provided with a first arc groove, the auxiliary buckle portion is provided with a second arc groove, and the first arc groove and the second arc groove are combined to form the first installation groove.

[0014] Furthermore, the first arc groove and the second arc groove are provided with a limiting strip to prevent the protective cover from turning.

[0015] By adopting the above technical solution, when the annular groove of the protective cover is clamped between the first arc groove and the second arc groove, the protective cover is clamped into the protective cover through the limiting strip and squeezed and deformed, effectively preventing the protective cover from axially rotating relative to the buckle body, and maintaining the stability of the buckle body in clamping the wiring harness.

[0016] The utility model is further configured such that the main snap-in portion is provided with a third arc groove for clamping the wiring harness, the auxiliary snap-in portion is provided with a second rectangular portion adapted to the third arc groove, the third arc groove and the second rectangular portion are combined to form a second installation groove, and the third arc groove and the second rectangular portion are provided with a limiting strip to prevent the protective cover from turning.

[0017] Using the above technical solution, the buckle main body structure is used to fix the wiring harness with a steering angle of 180°. The distance between the first mounting groove and the second mounting groove is the distance between the two points of the buckle main body fixing the wiring harness, ensuring a natural contour at the bending point of the wiring harness and preventing the wiring harness from being damaged due to excessive bending.

[0031] In the present invention, the protective cover 1 is a hollow rotating body made of rubber material, which is interference-connected with the wiring harness 7 through a press. The protective cover 1 is connected to the buckle body 2 as an adapter, and the buckle body 2 is fixed to the vehicle frame through the side clamping part 6, thereby achieving the fixation of the wiring harness 7. Since the buckle body 2 is formed by an integrated injection molding process, the bending deformation of the elastic part 4 makes the clamping strip 51 of the auxiliary buckle part 5 and the clamping slot 31 of the main buckle part 3 rotate and fit closely, thereby avoiding the loosening of the wiring harness 7 due to vehicle vibration or external force impact, without the need for additional fasteners or auxiliary accessories.

[0032] Combine Figure 4 As shown, in this embodiment, the main buckle part 3 is provided with a first vertical part 32, and the auxiliary buckle part 5 is provided with a second vertical part 52 for clamping the first vertical part 32.
