[0037] Example

[0038] See also Figures 1 to 8The present embodiment provides a multifunctional wire harness buckle for fixing a wire harness 5 and a connector 6 on a vehicle body, comprising a wire harness fixing portion 1, a connector fixing portion 2 and a plug-in portion, wherein the wire harness fixing portion 1 is arranged at one side of the connector fixing portion 2, the connector fixing portion 2 is arranged at the top end of the plug-in portion, and is used for detachably connecting the connector 6, the plug-in portion comprises a plug-in column 3, and the plug-in column 3 is evenly provided with a plurality of plug-in pads 31 along the length direction.

[0039] In this embodiment, for the convenience of explanation, the left and right directions of the horizontal plane are defined as the side faces, and the front and rear directions of the horizontal plane are defined as the ends.

[0040] The wiring harness 5 is fixed to the wiring harness fixing part 1 of the multifunctional wiring harness buckle (hereinafter referred to as the buckle) by using a strap 51, a suitable connector 6 is selected according to the needs, the connector 6 is installed on the connector fixing part 2, and finally the plug-in part of the buckle is inserted into the corresponding buckle mounting hole of the vehicle body to achieve installation, which is very convenient.

[0041] In order to prevent the buckle from falling off the vehicle body, a plurality of soft plug-in pads 31 are evenly arranged along the length direction at the front and rear ends of the plug-in post 3. When the plug-in post 3 is inserted into the mounting hole of the vehicle body sheet metal, the soft plug-in pad 31 is squeezed by the mounting hole to be deformed and passes through the mounting hole with the plug-in post 3. After the soft plug-in pad 31 passes through the mounting hole, it restores its original shape, thereby preventing the plug-in post 3 from falling off the mounting hole.

[0042] The multiple plug pads 3 along the length direction of the plug column 3 can adapt to the body sheet metal parts of different thicknesses. In this embodiment, the plug column 3 is provided with 5 plug pads 31 along the length direction, and the thickness of the body sheet metal parts that can be adapted is 0.7mm-6.5mm, which has a wide adaptation range. At the same time, the soft plug pad 31 can effectively prevent the buckle from shaking, avoiding the buckle from colliding with the body sheet metal parts to produce abnormal noise, affecting the user experience.

[0043] In one embodiment, the structure of the plug-in column 3 is improved to ensure the stability and reliability of the connection between the buckle and the vehicle body. Specifically, the plug-in column is provided with flexible barbs, and the flexible barbs are arranged on both sides of the plug-in column along the width direction.

[0044] In the present embodiment, the cross-section of the plug-in post 3 is roughly rectangular, and the plug-in pads 31 are arranged at both ends of the plug-in post 3 in the length direction. In order to ensure that the plug-in post 3 is not easily pulled out, flexible barbs 32 are arranged on the left and right sides of the plug-in post 3. Under the joint limiting effect of the flexible barbs 32 and the soft plug-in pads 31, the buckle is more difficult to be pulled out, and the increased contact area can further prevent the buckle from shaking on the body sheet metal, thereby increasing the reliability and stability of the buckle installed on the body sheet metal.

[0045] In one embodiment, the structure of the connector fixing portion 2 is improved to ensure reliable connection between the connector 6 and the connector fixing portion 2. Specifically, the connector fixing portion 2 is provided with a connector limiting structure, which includes an axial limiting structure and a lateral limiting structure.

[0046] In the present embodiment, in order to achieve the fixation of the connector 6 to the connector fixing part 2 of the buckle, the connector fixing part 2 is provided with a connector limiting structure, and the connector limiting structure includes an axial limiting structure and a lateral limiting structure. The axial limiting structure is connected to the connector 6, and the connector 6 can be axially limited. At the same time, the connector 6 can be laterally limited by the lateral limiting structure. The connector 6 is fixed on the connector fixing part 2 under the joint limiting action of the axial limiting structure and the lateral limiting structure.

[0047] Connector 6 is a standard connector. Connectors 6 of different specifications can be restricted in the snap-on connector fixing part 2 through an axial limiting structure. At the same time, when connector 6 needs to be replaced, the connector 6 can be released by toggling the lateral limiting structure so that the staff can replace the connector 6.

[0048] In one embodiment, the axial limiting structure is improved to ensure reliable connection between the connector 6 and the connector fixing portion 2. Specifically, the axial limiting structure is a house-shaped structure, the axial limiting structure is provided with depressions on both sides along the width, and a flange is provided on both sides of the top of the axial limiting structure, and the upper surface of the flange is flush with the upper surface of the axial limiting structure.

[0049] In the present embodiment, the axial limiting structure is a house-shaped structure. The axial limiting structure adopts a square structure, which can ensure the structural strength of the axial limiting structure and ensure the reliability and stability of the connector when it is installed in the axial limiting structure. The axial limiting structure is provided with recesses on both sides along the width direction, which can ensure the structural strength of the axial limiting structure while effectively reducing the use of axial limiting structure materials and reducing the weight of the axial limiting structure.

[0050] In order to limit the displacement of the connector in the up-and-down direction, a flange is provided on both sides of the top of the axial limiting structure along the width direction, and the upper surface of the flange is flush with the upper surface of the axial limiting structure, which is convenient for the installation of a standard connector. Connector 6 is a standard connector, and the bottom of standard connectors of different specifications are provided with a card slot, and the slot wall of the card slot is provided with a flange slot adapted to the flange at the top of the axial limiting structure. When installing, the card slot of the connector is inserted into the top of the axial limiting structure in the horizontal direction to achieve the limitation of connector 6 in the up-and-down direction. In order to facilitate alignment, a chamfer 211 is provided at one end of the flange 21 in the direction of installing the connector.

[0051] In one embodiment, the lateral limiting structure is improved to ensure the stable connection between the connector 6 and the connector fixing portion 2. Specifically, the lateral limiting structure includes a connector tongue 22, which is disposed at the end of the connector fixing portion 2, and a hook 23 is disposed at one end of the connector tongue 22 away from the connector fixing portion 2.

[0052] In this embodiment, in order to limit the forward and backward movement of the connector 6, a connector tongue 22 is provided at the end of the transverse limiting structure, and a hook 23 is provided at one end of the connector tongue 22 away from the connector fixing portion 2, and a connector limiting groove is formed between the hook 23 and the connector fixing portion 2. A protruding block 61 is provided at one end of the connector 6, and the protruding block 61 is adapted to the shape of the connector limiting groove.

[0053] During installation, align the slot of connector 6 with the flange 21 at the top of the axial limiting structure, and then move connector 6 from the end of the lateral limiting structure where the connector tongue 22 is provided toward the direction of the axial limiting structure. During this process, the connector tongue 22 is deformed under the action of the protruding block 61 of the connector. Continue to move connector 6. When connector 6 is installed in place, the protruding block 61 of connector 6 completely enters the connector limiting slot. At this time, the external force applied to the connector tongue 22 is removed, and the connector tongue 22 returns to its original state. At the same time, the hook 23 is also stuck on the end face of the protruding block 61 of the connector, thereby realizing the limitation of connector 6 in the front and rear directions.

[0054] In one embodiment, the structure of the hook 23 is improved to facilitate applying force to the hook 23 to release the connector 6. Specifically, a groove 24 is provided on the side of the hook 23 away from the connector fixing portion 2, and the groove 24 is formed from the free end of the connector tongue 22 toward the connector fixing portion 2, and two grooves 24 are symmetrically provided.

[0055] In this embodiment, when the user replaces the connector 6, the user needs to pull the hook 23 to disengage the hook 23 from the connected protruding block 61 to release the connector 6. In order to facilitate the user to pull the hook 23, a groove 24 is provided on the side of the hook 23 away from the connector fixing portion 2. The groove 24 is formed by being recessed from the free end of the connector tongue 22 toward the connector fixing portion 2, so that the user can apply force to the hook 23 with fingers or corresponding tools to deform the connector tongue 22 downward, so that the hook 23 is disengaged from the protruding block 61 of the connector, thereby releasing the connector 6. Preferably, two grooves 24 are symmetrically provided, so that the user can apply external force to the connector tongue 22 from any side of the connector tongue 22.

[0056] In one embodiment, the structure of the buckle is improved to ensure the stability and reliability of the connection between the buckle and the vehicle body. Specifically, a chuck 4 is provided between the connector fixing portion 2 and the plug-in portion, and the chuck 4 includes a top and an extension portion, and the extension portion extends from the top in an umbrella shape.

[0057] In this embodiment, an umbrella-shaped chuck 4 is provided between the connector fixing portion 2 and the plug-in portion. The cross-section of the chuck 4 gradually increases from the connector fixing portion 2 to the plug-in portion. The umbrella-shaped chuck 4 can play a better supporting and adjusting role, preventing the buckle from loosening and producing abnormal noise after matching the body sheet metal, and at the same time, it also has the function of sealing the installation hole of the body sheet metal to prevent foreign matter from entering.

[0058] In one embodiment, the structure of the harness fixing portion 1 is improved to ensure the reliability and stability of fixing the harness 5. Specifically, both ends of the harness fixing portion 1 are provided with a harness limiting structure 11, and the harness limiting structure 11 is in a "T" shape.

[0059] In this embodiment, a “T”-shaped harness limiting structure 11 is provided at both ends of the harness fixing portion 1 , which can block the harness belt 51 when the harness 5 is fixed, and effectively prevent the harness belt 51 from falling off from both ends of the harness fixing portion 1 .

[0060] In one embodiment, the structure of the harness fixing portion 1 is improved to facilitate fixing the harness 5. Specifically, the harness fixing portion 1 includes a harness fixing plate and a connecting plate, the harness fixing plate is connected to one side of the connector fixing portion 2 through the connecting plate, and the width of the connecting plate gradually narrows from the harness fixing plate to the connector fixing portion 2.

[0061] In this embodiment, the harness fixing plate is arranged on one side of the connector fixing portion 2 along the width direction through the connecting plate, so that the routing direction of the harness fixed by the connector 6 is consistent with the length direction of the harness fixing plate, which has a better organizing effect on the same-direction lines.

[0062] In one embodiment, the structure of the plug pad 31 is improved to ensure the fixing effect between the buckle and the vehicle body. Specifically, the plug pad 31 is in a semi-bowl-shaped structure.

[0063] In this embodiment, the cross-section of the plug pad 31 gradually decreases from the connector fixing portion 2 to the plug-in portion, making it easier to insert the buckle into the mounting hole of the vehicle body and more difficult to pull out from the mounting hole, thereby ensuring the fixing effect between the buckle and the vehicle body.

[0064] In one embodiment, the structure of the buckle is improved to ensure the reliability of the buckle structure and the wire harness fixing portion 1, the connector fixing portion 2 and the plug-in portion are an integrated structure.

[0065] In this embodiment, the harness fixing portion 1, the connector fixing portion 2 and the plug-in portion are made of plastic material, and the buckle can be an integrally formed structure, thereby effectively reducing the production cost of the buckle.

[0066] Similarly, the buckle can also be obtained by assembling three parts: the wire harness fixing part 1, the connector fixing part 2 and the plug-in part.

[0067] From the above description, it can be seen that the beneficial effects of the utility model are: providing a wire harness fixing buckle with an integrated connector mounting structure, which can fix the wire harness through the wire harness fixing part, and install wire harness connectors of different specifications through the connector fixing part as needed, and finally install the buckle on the vehicle body through the plug-in part, thereby ensuring the reliability and safety of the wire harness and connector fixation. The buckle occupies a small space, has low cost, high assembly efficiency, and has promotion value.

[0068] It is easy for those skilled in the art to understand that the above-mentioned implementation modes can be freely combined and superimposed without conflict.

[0069] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
