Description

Technical Field

[0001] This application relates to the technical field of vehicle wiring harness fixing, and particularly to a wiring harness pipe clamp. Background Art

[0002] The wiring harness pipe clamp is mainly used as a tool for fixing vehicle wiring harnesses. The wiring harnesses with different orientations are installed at fixed positions on the vehicle through the claws on the pipe clamp. However, the claws of the existing wiring harness pipe clamps are fixed only by several limiting ribs, which are not only easily affected by the vibration of the vehicle body and change the direction, making the wiring harness fixing unstable, thus causing the wiring harness to shake and affecting signal transmission and generating abnormal noises. Moreover, when installing, the installation angle of the claws is not flexible enough, so that the wiring harness pipe clamp cannot be flexibly adjusted at different angles according to the wiring harnesses with different orientations on the vehicle. Summary of the Utility Model

[0003] Based on this, it is necessary to provide a wiring harness pipe clamp that can ensure the fixing strength of the wiring harness, make the wiring harness not easily affected by the shaking of the vehicle, and can be flexibly adjusted in angle during installation.

[0004] To solve the above technical problems, the present application provides the following technical solutions:

[0005] A wiring harness pipe clamp, the wiring harness pipe clamp includes: an anchor for connecting to a corresponding installation part; a connecting seat having opposite sides, one side of which is connected to the anchor and the other side is provided with a coupling hole; a claw including an arm for clamping the wiring harness and a root rotatably inserted into the coupling hole, and an anti-rotation structure that cooperates with each other is provided between the root and the connecting seat; wherein, the anti-rotation structure has opposite holding states and release states. In the holding state, the root is restricted to a fixed angle; in the release state, the root is configured to allow rotation within the coupling hole.

[0006] It can be understood that by setting the anti-rotation structure in the present application, the anti-rotation structure can limit the root in a fixed position, that is, when the wiring harness pipe clamp is in the holding state, the root of the claw cannot rotate relative to the connecting seat, avoiding the angle change of the claw part of the wiring harness pipe clamp during the shaking of the vehicle, and increasing the fixing strength of the wiring harness; at the same time, during the installation of the wiring harness pipe clamp, the angle can be adjusted according to different wiring harness positions by the rotation of the root within the coupling hole, that is, when the wiring harness pipe clamp is in the release state, thus increasing the flexibility of the installation of the wiring harness pipe clamp.

[0007] In one embodiment, the root and the coupling hole have different insertion depths, and respectively correspond to a first insertion position and a second insertion position; wherein, when in the first insertion position, the anti-rotation structure is in the holding state; when in the second insertion position, the insertion depth is shallower than the first insertion position, and the anti-rotation structure is in the release state.

[0008] It can be understood that by means of the anti-rotation structure controlled by the insertion depth, only a simple plugging and unplugging operation is required to switch between the holding state and the releasing state, simplifying the structure and facilitating the operation.

[0009] In one embodiment, the connecting seat is columnar as a whole and has an axial direction. Along the axial direction, one end of the connecting seat is hinged to the anchoring member through a pivot, and the engaging hole is open at the end face of the other end of the connecting seat.

[0010] In one embodiment, the outer periphery of the root portion is provided with an annular step, and abuts against the connecting seat through the annular step. The anti-rotation structure is arranged between the annular step and the end face of the connecting seat.

[0011] It can be understood that the arrangement of the annular step on the root portion enables it to engage and abut against the connecting seat, so as to ensure that when the anti-rotation structure is in the holding state, the claw does not rotate, avoiding the claw rotation during the vehicle shaking process from driving the wire harness to collide with the environment and causing abnormal noises in the vehicle.

[0012] In one embodiment, the anti-rotation structure includes a first tooth and a second tooth. The first tooth is annularly distributed on the side of the annular step facing the connecting seat; the second tooth is located on the connecting seat and is annularly distributed on the outer periphery of the engaging hole. The anti-rotation structure meshes with the first tooth in the holding state and is separated from the first tooth in the releasing state.

[0013] It can be understood that the structural arrangement of the first tooth and the second tooth strengthens the connection structure between the connecting seat and the claw, making the holding state of the anti-rotation structure more stable. And when the first tooth and the second tooth are separated, the anti-rotation structure can be changed to the releasing state to adjust the claw angle; meanwhile, the setting position of the anti-rotation structure 40 optimizes the volume of the wire harness pipe clip 100, eliminating the need for a large axial dimension between the radial inner wall and the outer wall, thus saving the installation space and shortening the stroke of switching the plugging and unplugging states, making the operation more convenient.

[0014] In one embodiment, the connecting seat and the anchoring member are hinged and cooperated around the axis direction of the engaging hole, and the root portion rotates and cooperates with respect to the engaging hole around the direction perpendicular to the axis of the engaging hole.

[0015] It can be understood that the anchoring member and the claw root portion are respectively connected and cooperated with the connecting seat, which can increase the flexibility of the wire harness pipe clip and improve its convenience during installation and disassembly.

[0016] In one embodiment, a positioning structure that cooperates with each other is provided between the root portion and the inner edge of the engaging hole for holding the root portion at a fixed insertion position.

[0017] In one embodiment, the positioning structure includes an annular clamping groove and a positioning protrusion. A plurality of annular clamping grooves are arranged along the inner wall of the engaging hole, and the positioning protrusion is arranged on the outer periphery of the root and cooperates with the annular clamping groove at the corresponding position.

[0018] It can be understood that the plurality of annular clamping grooves can cooperate and connect with the positioning protrusions correspondingly, further increasing the stability and firmness of the wire harness pipe clamp in the holding state, so that the fixed wire harness is not easily collided with the environment and generates abnormal noises.

[0019] In one embodiment, the positioning protrusion is arranged in an annular shape.

[0020] It can be understood that the annular shape setting enables the claw 30 to rotate to any angle, and the annular clamping groove 51 and the positioning protrusion 52 can match each other at any position in the circumferential direction, avoiding tilting and loosening.

[0021] In one embodiment, the arm portion is generally C-shaped and includes two elastic arms that cooperate with each other. The root is connected to the intersection of the two elastic arms; the opening portion of the C shape has a guiding bend that turns outwards relatively.

[0022] It can be understood that the setting of the elastic arms makes the claw more inclusive. When the vehicle vibrates, the vehicle wire harness fixed to the wire harness pipe clamp has an elastic space, so as to increase the reliability of the claw arm portion and make it not easily break; and the guiding bend at the opening portion facilitates the orderly fixing of the vehicle wire harness.

[0023] Compared with the prior art, by providing a rotation prevention structure, the rotation prevention structure can limit the root at a fixed position, that is, the wire harness pipe clamp is in a holding state, so that the root of the claw cannot rotate relative to the connecting seat, avoiding the angle change of the claw portion of the wire harness pipe clamp during the vehicle shaking process, and increasing the strength of the wire harness fixing; at the same time, during the installation of the wire harness pipe clamp, the angle can be adjusted according to different wire harness positions by rotating the root in the engaging hole, that is, the wire harness pipe clamp is in a released state. In this way, the flexibility of the wire harness pipe clamp installation is increased. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Unless otherwise defined, all technical and scientific terms used in the specification of this application have the same meaning as commonly understood by those skilled in the technical field to which this application pertains. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the specification of this application includes any and all combinations of one or more of the related listed items.

[0036] Please refer to Figures 1 to 4 , this application provides a wire harness pipe clip 100, which is applied to the fixation of the wire harness of a vehicle. It is mainly used to stably clamp and fix the wire harnesses in different directions on the vehicle, so that the wire harness is not affected by the shaking of the vehicle and does not make abnormal noises due to collisions, and can flexibly adjust the angle of the wire harness pipe clip when installing the wire harness pipe clip part, thereby improving the strength and efficiency of the wire harness fixation.

[0037] As Figures 1 to 3 shown, the wire harness pipe clip includes an anchor 10, a connecting seat 20 and a claw 30. The anchor 10 is used to connect to the corresponding installation part; the connecting seat 20 has opposite sides, one side of which is connected to the anchor 10, and the other side is provided with a mating hole 21; the claw 30 includes an arm 31 for clamping the wire harness and a root 32 rotatably inserted into the mating hole 21. A rotation prevention structure 40 is provided between the root 32 and the connecting seat 20; wherein, the rotation prevention structure 40 has opposite holding states and release states. In the holding state, the root 32 is restricted to a fixed angle; in the release state, the root 32 is configured to allow rotation within the mating hole 21.

[0038] It should be noted that the direction of the wire harness pipe clip 100 is fixed only by several limiting ribs, and the fixing strength is insufficient, making it easy to change direction and rub during the shaking of the vehicle, resulting in wear and loosening of its fit. At this time, the wire harness will collide with the environment as the vehicle shakes, affecting signal transmission and generating abnormal noises. Moreover, when installing the wire harness pipe clip, the installation angle of the claw 30 is not flexible enough, making the wire harness pipe clip 100 unable to be flexibly adjusted at different angles according to the wire harnesses with different orientations on the vehicle. In this application, the wire harness pipe clip 100 is provided with an anti-rotation structure 40. The anti-rotation structure 40 can limit the root 32 of the claw 30 in a fixed position, that is, the wire harness pipe clip 100 is in a holding state, making it unable to rotate relative to the connecting seat 20, which can prevent the claw 30 from changing its angle during vehicle vibration, thereby increasing the strength of wire harness fixation, making the claw 30 part of the wire harness pipe clip 100 not easily worn and loosened, and ensuring that the wire harness is always fixed in the accurate fixing position. At the same time, during the installation process of the wire harness pipe clip 100, the angle can be adjusted according to the positions of different wire harnesses by rotating the root 32 in the mating hole, even when the wire harness pipe clip 100 is in the released state. In this way, the flexibility of installing the wire harness pipe clip 100 is increased, facilitating installation.

[0039] Here, the connection between the anchor 10 and the corresponding installation part can be a connection method such as snap connection or riveting, depending on the actual installation requirements.

[0040] Such as Figure 1 and Figure 2 As shown, the anchor 10 is hinged to the connecting seat 20 through a pivot 11. It can be understood that the connection structure between the anchor 10 and the connecting seat 20 by hinging through the pivot 11 is relatively simple and practical, ensuring the fixed connection between the anchor 10 and the connecting seat 20 while simplifying their connection part and saving costs.

[0041] In one embodiment, please continue to refer to Figure 2 , the connecting seat 20 is integrally set as a column and has an axial direction, and the end face of the connecting seat 20 is connected to the claw 30 along the axial direction. The columnar structure can satisfy the rotation of the claw 30 relative to the connecting seat 20 to facilitate the adjustment of the angle of the wire harness pipe clip 100.

[0042] Furthermore, the connecting seat 20 is hingedly engaged with the anchor 10 around the axis of the mating hole 21. The hinged engagement method enables relative movement between the two, so that when adjusting the angle of the claw 30 according to the specific situation of vehicle wire harness assembly, the connecting seat 20 and the anchor 10 can rotate and be fixed synchronously or separately, improving the convenience during installation and disassembly.

[0043] Such as Figures 1 to 3As shown, the arm 31 is generally C-shaped, including two elastic arms 311 that cooperate with each other. The root 32 is connected to the intersection of the two elastic arms 311; the opening of the C-shape has a guiding bend 312 that is turned outwards relatively. The arrangement of the elastic arms 311 makes the claw 30 more inclusive, so that when the vehicle vibrates, the vehicle wiring harness fixed to the wiring harness pipe clamp 100 has an elastic space, which increases the reliability of the claw arm 31 and makes it not easy to break; and the guiding bend 312 at the opening is convenient for the orderly fixing of the vehicle wiring harness.

[0044] Exemplarily, the outer periphery of the root 32 is provided with an annular step 321 and abuts against the connecting seat 20 through the annular step 321; and the root 32 is rotationally matched with the mating hole 21 in the vertical direction around the axis of the mating hole 21. In this way, the annular step 321 can be meshed and abutted with the connecting seat, so as to ensure that the claw is in a holding state, avoid its collision with the environment during the vehicle shaking, and cause abnormal noise in the vehicle. Moreover, the rotational mating of the root 32 and the mating hole 21 increases the flexibility of the wiring harness pipe clamp 100 and is convenient for adjusting the angle of the claw 30.

[0045] As Figures 2 to 4 shown, the root 32 and the mating hole 21 have different insertion depths, corresponding to the first insertion position 41 and the second insertion position 42 respectively; among them, when in the first insertion position 41, the anti-rotation structure 40 is in a holding state; when in the second insertion position 42, the insertion depth is shallower than that in the first insertion position 41, and the anti-rotation structure 40 is in a released state. In this way, through a simple plugging and unplugging operation, it can be adjusted to the holding state or the released state, making the structure simple and the operation convenient.

[0046] Furthermore, the anti-rotation structure 40 is arranged between the annular step 321 and the end face of the connecting seat 20, including a first tooth 43 and a second tooth 44. The first tooth 43 is distributed annularly on the side of the annular step 321 facing the connecting seat 20; the second tooth 44 is located on the connecting seat 20 and is distributed annularly on the outer periphery of the mating hole 21. The anti-rotation structure 40 meshes with the first tooth 43 in the holding state and separates from the first tooth 43 in the released state. The structural arrangement of the first tooth 43 and the second tooth 44 strengthens the connection structure between the connecting seat 20 and the claw 30, making the holding state of the anti-rotation structure 40 more stable. Moreover, when the first tooth 43 and the second tooth 44 are separated, the anti-rotation structure can be changed to the released state to adjust the angle of the claw 30; at the same time, the setting position of the anti-rotation structure 40 optimizes the volume of the wiring harness pipe clamp 100, does not require a large axial dimension between the radial inner wall and the outer wall, thereby saving the installation space and shortening the stroke of the plugging and unplugging switching state, making the operation more convenient.

[0047] Please continue to refer to Figure 4 , the positioning structure 50 is arranged between the inner edges of the root 32 and the mating hole 21 and is used to hold the root 32 in a fixed insertion position.

[0048] For example, the positioning structure 50 includes an annular slot 51 and a positioning protrusion 52. Multiple annular slots 51 are arranged along the inner wall of the coupling hole 21, and the positioning protrusion 52 is arranged on the outer periphery of the root portion 32 and cooperates with the annular slot 51 at the corresponding position. It can be understood that multiple annular slots 51 can cooperate and connect with the positioning protrusion 52 correspondingly, further increasing the stability and firmness of the wire harness pipe clamp 100 in the holding state, so that the fixed wire harness is not easily collided with the environment and generates abnormal noises.

[0049] Preferably, the number of the annular slots 51 can be set to two, four, six, etc., and the number of the positioning protrusions 52 is correspondingly set to one, two, three, etc., so that the positioning protrusion 52 can be adjusted on the annular slot 51 according to the depth requirements of insertion and extraction to ensure the cooperation between the annular slot 51 and the positioning protrusion 52 and realize the switching between the holding state and the releasing state.

[0050] Furthermore, the positioning protrusion 52 is arranged in an annular shape. The annular shape makes it easy for the positioning protrusion 52 to disengage from and engage with the annular slot 51, further realizing the switching between the holding state and the releasing state, and can increase the convenience of installation and disassembly of the wire harness pipe clamp 100; at the same time, the annular shape setting enables the claw 30 to rotate to any angle, and the annular slot 51 and the positioning protrusion 52 can match each other at any position in the circumferential direction, avoiding tilting and loosening.

[0051] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0052] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
