Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, and in particular to an automotive wiring harness clamp. Background Technology

[0002] In automotive wiring harness systems, traditional wiring harness clamps, as key fixing components, typically consist of cable ties and the clamp body. The two are assembled through a clearance fit between a shaft and a cylindrical hole. They are mainly used to reliably fix the wiring harness to the surface of tubular components (such as oil pipes, brake pipes, etc.). The rotational freedom formed by the shaft-hole fit allows the clamp to adjust its angle around the installation axis to adapt to the complex path requirements of the wiring harness. At the same time, it maintains a preset safe distance between the wiring harness and surrounding components (such as body sheet metal, moving parts, etc.) to avoid mechanical wear or electrical failures caused by direct contact.

[0003] However, due to the lack of an effective locking mechanism between the shaft and the cylindrical hole, the connection between the cable tie and the pipe clamp cannot be rigidly fixed. Under dynamic conditions such as vehicle vibration, the weight of the wiring harness itself, or external airflow disturbances, the cable tie is prone to unexpected rotation around the shaft, causing the actual route of the wiring harness to deviate from the design path, which can easily lead to accidental interference between the wiring harness and surrounding components. Utility Model Content

[0004] The purpose of this utility model is to provide an automotive wiring harness clamp to solve the problem that the relative positions of the cable ties and the clamp cannot be fixed in the existing design.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An automotive wiring harness clamp includes: a cable tie and a clamp, wherein a first connector is formed on the cable tie and a second connector is formed on the clamp, the first connector and the second connector being rotatably connected; a locking pin for mounting on the first connector, the locking pin having a first snap-fit ​​element; and a second snap-fit ​​element formed on the second connector, wherein the first snap-fit ​​element can snap into the second snap-fit ​​element to lock the first connector and the second connector.

[0006] According to the above-mentioned technical means, the first locking member on the locking pin and the second locking member of the second connector in this utility model form a rigid locking engagement, which can completely lock the relative rotational freedom of the first connector and the second connector, fundamentally eliminating the risk of unexpected rotation of the cable tie under dynamic working conditions, and ensuring that the wire harness direction is strictly consistent with the design path.

[0007] Furthermore, a first through hole is formed on the first connector along the first direction, and the second connector is rotatably inserted into the first through hole.

[0008] According to the above technical means, the first through hole provides an insertion channel for the second connector and ensures that the second connector can rotate along the axis of the first through hole.

[0009] Furthermore, a second through hole is formed on the first connector along the second direction, and the second through hole is connected to the first through hole; the locking pin can pass through the second through hole, so that the first snap-fit ​​member is snapped into the second snap-fit ​​member in the first through hole; the first direction is perpendicular to the second direction.

[0010] According to the above technical means, the second through hole is perpendicularly connected to the first through hole along the second direction, so that the locking pin can be inserted from the direction perpendicular to the rotation axis, ensuring that the first locking member of the locking pin can directly act on the second locking member of the second connector to form a rigid locking.

[0011] Furthermore, the second snap-fit ​​component comprises multiple slots, each slot being evenly distributed circumferentially along the second connector; the first snap-fit ​​component can snap into each slot to lock the first connector and the second connector.

[0012] Based on the above technical means, each slot is evenly distributed around the second connector, providing multiple discrete locking positions for the rotation angle of the cable tie, so that when adjusting the direction of the wire harness, the operator can select any slot for locking according to the design requirements.

[0013] Furthermore, a third locking member is formed in the second through hole, and a fourth locking member is also formed on the locking pin. The third locking member can engage with the fourth locking member to prevent the locking pin from falling out of the second through hole.

[0014] According to the above technical means, the third and fourth locking components are directly integrated into the inner wall of the second through hole and the surface of the locking pin. At the same time, since the locking pin is inserted into the second through hole, it can effectively constrain the axial and radial displacement of the locking pin and avoid the locking pin from accidentally falling off due to vibration, impact or misoperation.

[0015] Furthermore, the third locking member has a ratchet structure, and the fourth locking member has a pawl structure.

[0016] According to the above technical means, the ratchet structure of the third locking component and the pawl of the fourth locking component form a mechanical one-way lock. During the insertion of the locking pin, the pawl slides along the inclined surface of the ratchet to achieve unobstructed assembly. When subjected to a reverse load, the pawl is embedded in the back angle of the ratchet to form a hard stop and prevent the locking pin from loosening.

[0017] Furthermore, a nail head is formed on the end of the locking pin away from the first snap-fit ​​member.

[0018] Based on the aforementioned technical means, operators can directly apply axial thrust or hammering force through the nail head, achieving rapid insertion without auxiliary tools. Simultaneously, the nail head and the end face of the second through hole form a rigid stop structure. When the locking nail is inserted to the designed depth, the bottom surface of the nail head fits against the end face of the second through hole, achieving precise positioning through surface contact.

[0019] Furthermore, the pipe clamp includes a clamping element for clamping onto the pipe fittings of the vehicle.

[0020] Furthermore, the pipe clamp also includes an anti-slip pad, which is installed on the inside of the clamping member.

[0021] Based on the above technical means, the anti-slip mat is used to increase friction, enhance the stability of clamping, and prevent the pipe fitting from sliding. At the same time, the anti-slip mat can also protect the surface of the pipe fitting.

[0022] Furthermore, the pipe clamp also includes a strap, the clamping member has a U-shaped structure and two opposing ends are formed on the clamping member; one end of the strap is fixed to one end of the clamping member, and the other end of the strap can be snapped onto the other end of the clamping member.

[0023] Based on the above technical means, the arc-shaped wrapping design of the U-shaped clamp, combined with the strap, forms an adjustable snap-fit ​​structure, so that the pipe clamp can dynamically adapt to pipe fittings of various diameters.

[0024] The beneficial effects achieved by this utility model are: In this invention, the first locking member on the locking pin and the second locking member of the second connector form a rigid locking engagement, which can completely lock the relative rotational freedom of the first connector and the second connector, fundamentally eliminating the risk of unexpected rotation of the cable tie under dynamic working conditions, and ensuring that the wire harness routing is strictly consistent with the design path.

The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0033] The technical solution of this embodiment will be described in detail below with reference to the accompanying drawings.

[0034] like Figure 1 As shown, an automotive wiring harness clamp includes: a cable tie 1 and a clamp 2, wherein a first connector 11 is formed on the cable tie 1 and a second connector 21 is formed on the clamp 2, and the first connector 11 and the second connector 21 are rotatably connected; a locking pin 3 is used to be installed on the first connector 11, and a first snap-fit ​​31 is formed on the locking pin 3; a second snap-fit ​​211 is formed on the second connector 21, and the first snap-fit ​​31 can snap-fit ​​with the second snap-fit ​​211 to lock the first connector 11 and the second connector 21.

[0035] In this embodiment, the first snap-fit ​​member 31 on the locking pin 3 and the second snap-fit ​​member 211 of the second connector 21 form a rigid snap-fit ​​engagement, which can completely lock the relative rotational freedom of the first connector 11 and the second connector 21, fundamentally eliminating the risk of unexpected rotation of the cable tie 1 under dynamic working conditions, and ensuring that the wire harness route is strictly consistent with the design path.

[0036] In this embodiment, the wire harness clamp is used in the following way: The pipe clamp 2 is fitted onto the surface of automotive pipe components (such as oil pipes and brake pipes) to ensure that the pipe clamp 2 is fixed in axial position with the pipe component. At this time, the second snap-fit ​​member 211 on the second connector 21 is in the snap-fit ​​state.

[0037] The first connector 11 of the cable tie 1 and the second connector 21 of the tube clamp 2 are rotatably connected through a shaft hole. At this time, the cable tie 1 can rotate freely around the rotation axis of the first connector 11 and the second connector 21. According to the design direction of the wire harness, the rotation angle of the cable tie 1 is manually adjusted so that the wire harness fixing part of the cable tie 1 forms a preset angle with the tube component.

[0038] Push the locking pin 3 into the first connector 11, so that the first locking member 31 of the locking pin 3 approaches the second locking member 211 of the second connector 21, until the first locking member 31 and the second locking member 211 form a rigid locking engagement. This locks the relative rotational freedom of the first connector 11 and the second connector 21, preventing the cable tie 1 from rotating further and fixing the wire harness routing on the designed path.

[0039] like Figure 2 and Figure 4 As shown, a first through hole 111 is formed on the first connector 11 along the first direction, and the second connector 21 is rotatably inserted into the first through hole 111.

[0040] The first through hole 111 provides a insertion channel for the second connector 21 and ensures that the second connector 21 can rotate along the axis of the first through hole 111.

[0041] like Figure 2 and Figure 4As shown, a second through hole 112 is formed on the first connector 11 along the second direction, and the second through hole 112 is connected to the first through hole 111; the locking pin 3 can pass through the second through hole 112, so that the first snap-fit ​​31 is snapped into the second snap-fit ​​211 in the first through hole 111; the first direction is perpendicular to the second direction.

[0042] The second through hole 112 is perpendicularly connected to the first through hole 111 along the second direction, so that the locking pin 3 can be inserted from the direction perpendicular to the rotation axis, ensuring that the first snap-fit ​​member 31 of the locking pin 3 can directly act on the second snap-fit ​​member 211 of the second connector 21 to form a rigid snap-fit ​​lock.

[0043] like Figure 2 and Figure 4 As shown, the second snap-fit ​​member 211 has multiple slots, and each slot is evenly distributed around the second connector 21. The first snap-fit ​​member 31 can snap into each slot to lock the first connector 11 and the second connector 21.

[0044] Each slot is evenly distributed around the second connector 21, providing multiple discrete locking positions for the rotation angle of the cable tie 1, so that when adjusting the direction of the wire harness, the operator can select any slot for locking according to the design requirements.

[0045] In this embodiment, each slot extends axially along the second connector 21, and the first connector 31 is designed with a matching long flat wedge structure. Its wedge-shaped inclined surface forms a mechanical interlock with the slot, which improves the stability and vibration resistance of the wire harness tube when locked.

[0046] like Figure 2 and Figure 4 As shown, a third locking member 113 is formed in the second through hole 112, and a fourth locking member 32 is also formed on the locking pin 3. The third locking member 113 can engage with the fourth locking member 32 to prevent the locking pin 3 from falling out of the second through hole 112.

[0047] The third locking member 113 and the fourth locking member 32 are directly integrated into the inner wall of the second through hole 112 and the surface of the locking pin 3. At the same time, since the locking pin 3 is inserted into the second through hole 112, it can effectively constrain the axial and radial displacement of the locking pin 3 and prevent the locking pin from accidentally falling off due to vibration, impact or misoperation.

[0048] like Figure 4 As shown, the third connector 113 has a ratchet structure, and the fourth connector 32 has a pawl structure.

[0049] The ratchet structure of the third locking member 113 and the pawl of the fourth locking member 32 form a mechanical one-way lock. During the insertion of the locking pin 3, the pawl slides along the inclined surface of the ratchet to achieve unobstructed assembly. When subjected to a reverse load, the pawl engages with the back angle of the ratchet to form a hard stop, preventing the locking pin 3 from loosening.

[0050] At least two ratchet-structured third locking members 113 can be formed within the second through hole 112, and at least two pawl-structured fourth locking members 32 can be formed on the surface of the locking pin 3. For example... Figure 3 As shown, a third locking member 113 is formed on each of the opposite sides of the inner wall of the second through hole 112. The positions of the two third locking members 113 are staggered (along the insertion direction) to make the installation smoother. At the same time, a multi-level locking structure is formed to improve the connection stability.

[0051] like Figure 2 and Figure 4 As shown, a nail head 33 is formed on the end of the locking nail 3 that is away from the first snap fastener 31.

[0052] Operators can directly apply axial thrust or hammering force through the nail head 33, achieving rapid insertion without auxiliary tools. At the same time, the nail head 33 and the end face of the second through hole 112 form a rigid stop structure. When the locking nail 3 is inserted to the designed depth, the bottom surface of the nail head 33 fits against the end face of the second through hole 112, achieving precise positioning through surface contact.

[0053] In this preferred embodiment, the nail head 33 may have anti-slip texture.

[0054] like Figure 2 and Figure 3 As shown, the pipe clamp 2 includes a clamping member 22, which is used to clamp onto the pipe fittings of the vehicle.

[0055] like Figure 2 and Figure 3 As shown, the pipe clamp 2 also includes an anti-slip pad 23, which is installed inside the clamping member 22.

[0056] According to the above technical means, the anti-slip pad 23 is used to increase friction, enhance the stability of clamping, and prevent the pipe fitting from sliding. At the same time, the anti-slip pad 23 can also protect the surface of the pipe fitting.

[0057] like Figure 2 and Figure 3 As shown, the pipe clamp 2 also includes a strap 24. The clamping member 22 has a U-shaped structure and two opposing ends are formed on the clamping member 22. One end of the strap 24 is fixed to one end of the clamping member 22, and the other end of the strap 24 can be snapped onto the other end of the clamping member 22.

[0058] The arc-shaped wrapping design of the U-shaped clamp 22, combined with the strap 24, forms an adjustable snap-fit ​​structure, so that the pipe clamp 2 can dynamically adapt to pipe fittings of various diameters.

[0059] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made based on the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
