Description

Technical Field

[0001] This utility model relates to the field of clamp technology, and in particular to a wire harness fixing clamp. Background Technology

[0002] In electric or hybrid vehicles, the battery system is one of the core components, involving numerous electrical connections. It requires wiring harnesses to achieve functions such as power transmission and signal interaction. To ensure that these wiring harnesses can be fixed in an orderly manner, clamps are usually used to tighten the wiring harnesses individually, and then the clamps are fixed to the wiring harness fixing frame inside the vehicle. This ensures that the wiring harnesses are fixed in the appropriate position according to certain rules and order, preventing the wiring harnesses from getting tangled, shaking, or colliding with other components during vehicle movement.

[0003] However, after the existing clamps tighten and fix the wire harness, it is usually necessary to use screws or bolts to lock the two ends of the clamps, and then fix the outer periphery of the clamps to the wire harness fixing frame with screws or bolts. The installation process is cumbersome and disassembly is very inconvenient, which affects the later maintenance. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art, the present invention provides a wire harness fixing clamp, wherein the locking notch of the clamp body is engaged with the second connecting arm through the first connecting arm. After the wire harness is fixed, the outer periphery of the clamp body can be connected to the outside through the connector on the clamp body. No tools are needed for disassembly and assembly, making the operation more convenient.

[0010] Furthermore, the side of the snap-fit ​​arm is provided with a snap-fit ​​connector, which is used to be pressed against the inner wall of the snap-fit ​​hole when it is inserted into the snap-fit ​​hole, so as to guide the two snap-fit ​​arms to approach each other; the snap-fit ​​connector is used to pass through the snap-fit ​​hole and snap-fit ​​after the two snap-fit ​​arms approach each other.

[0011] Furthermore, the snap-fit ​​connector is provided with a guide slope, which slides in conjunction with the inner wall of the snap-fit ​​hole and is pressed against the inner wall of the snap-fit ​​hole to guide the snap-fit ​​connector to snap into or out of the snap-fit ​​hole.

[0012] Furthermore, multiple connectors are provided, and at least one connector is engaged with an external structure.

[0013] Furthermore, at least one of the connectors is a snap-fit.

[0014] Furthermore, the outer periphery of the clamp body is provided with a locking block, and the locking block is provided with a locking groove.

[0023] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0024] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0026] See Figures 1 to 3 This utility model discloses a wire harness fixing clamp, including a clamp body 10, the clamp body 10 having a locking notch 11, a first connecting arm 12 and a second connecting arm 13 respectively provided on both sides of the locking notch 11, the first connecting arm 12 and the second connecting arm 13 engaging to open or close the locking notch 11, and a connector 14 provided on the clamp body 10 for connecting with an external structure.

[0027] Based on the above structure, during assembly, the first connecting arm 12 can be equipped with a buckle, hook, or snap-fit ​​post, while the second connecting arm 13 can be equipped with a corresponding slot 151, snap-fit ​​hole 121, or snap ring, so that the first connecting arm 12 and the second connecting arm 13 can be engaged and connected. After the clamp body 10 is fitted around the outer periphery of the wire harness, the worker only needs to press the first connecting arm 12 lightly to bring it close to the second connecting arm 13. At this time, the buckle, hook, or snap-fit ​​post on the first connecting arm 12 will undergo elastic deformation under a certain pressure, and then snap into the corresponding slot 151, snap-fit ​​hole 121, or snap ring on the second connecting arm 13, thereby achieving connection and making the locking notch 11 closed to lock the wire harness. In this way, when installing, the operator only needs to apply external force to the first connecting arm 12 or the second connecting arm 13 to make the two engage and connect, which greatly improves the assembly efficiency.

[0028] Similarly, when the wiring harness needs to be replaced, the buckles, hooks or locking pins on the first connecting arm 12 are disengaged from the slot 151 or locking hole 121 by applying appropriate external force, so that the locking notch 11 is open. At this time, the clamp body 10 is disassembled, and the wiring harness can be taken out and replaced, which is convenient for technicians to inspect and maintain the wiring harness.

[0029] Furthermore, once the wiring harness is secured, since the clamp body 10 has a connector 14 on its outer periphery, the wiring harness can be locked to the clamp body 10 by connecting the connector 14 to the connecting part (such as a mounting hole or a snap-fit ​​groove) on the external structure (such as a fixing frame for securing the wiring harness). This ensures that the wiring harness is fixed in the appropriate position according to certain rules and order, preventing the wiring harness from getting tangled, shaking, or colliding with other components during vehicle movement.

[0030] Specifically, taking the fixed frame for fixing the wire harness as an example, during assembly, the connector 14 can be a snap-fit ​​structure such as a snap-fit ​​strip, buckle or hook on the clamp body 10. When connecting to the fixed frame, simply snap the connector 14 into the slot 151 or bayonet provided on the fixed frame to easily connect the clamp body 10 to the fixed frame without the need for external tools, making installation more convenient.

[0031] Of course, the connector 14 can also be a block 15 structure formed on the outer periphery of the clamp body 10. By setting a snap-fit ​​groove or a snap-fit ​​opening on the block 15, when the structure on the fixed frame used to fix the clamp body 10 is a protruding buckle or a snap-fit ​​post or other block structure, the protruding block structure on the fixed frame can be snapped into the snap-fit ​​groove or snap-fit ​​opening on the connector 14, and the snap-fit ​​connection can also be achieved, which is convenient to operate.

[0032] In addition, the connector 14 can also be a connecting rod or a connecting column formed on the outer periphery of the clamp body 10. By setting threads on the outer periphery of the connecting column or rod, the outer periphery of the clamp body 10 has a threaded rod or other structure. In this way, when there are threaded holes on the fixed frame, the worker can directly connect the clamp body 10 to the fixed frame by rotating the connector 14 and screwing it into the threaded hole. Similarly, the connection can be achieved without the aid of external tools.

[0033] Therefore, when using the speed limiting fixing clamp in this embodiment, the entire wire harness fixing process can be completed without the need for external tools. The clamp body 10 can be fitted onto the outer periphery of the wire harness, and the clamp body 10 can be fixed to the fixing frame without the need for external connectors 14. The entire installation process is simple and convenient, and facilitates later maintenance.

[0034] Specifically, in this embodiment, multiple connectors 14 are provided. These multiple connectors 14 can be one, two, or three of the structures described above, so that the clamp body 10 can be connected to the external structure through multiple connection methods to adapt to various types of fixed frames, thus making the application range of the clamp body 10 wider.

[0035] More specifically, at least one of the connectors is connected to the external structure using a snap-fit ​​connection. This allows workers to install the clamp without tools, reducing installation time and improving efficiency.

[0036] Preferably, in this embodiment, when there are multiple connectors 14, at least one of them is a snap-fit. The snap-fit ​​can be designed according to the standard size of the universal slot 151 on the fixed frame, so that after the wire harness is connected to the clamp, it can be engaged with the fixed frame through the snap-fit. In this way, the worker only needs to align the snap-fit ​​on the clamp with the corresponding slot 151 on the fixed frame, and then gently press or push it in to quickly complete the connection between the clamp and the fixed frame. Compared with traditional screw fixing methods, there is no need to use tools to tighten the screws, which reduces the installation time and improves the installation efficiency.

[0037] Furthermore, the first connecting arm 12 is provided with a snap-fit ​​hole 121, and the second connecting arm 13 is provided with a snap-fit ​​member 131, which snaps into the snap-fit ​​hole 121.

[0038] Specifically, during assembly, after the wire harness is fixed, the operator can gently press the snap-fit ​​131 into the snap-fit ​​hole 121 so that the first connecting arm 12 and the second connecting arm 13 can be engaged and connected. This makes the operation convenient and the disassembly and assembly easier.

[0039] It should be noted that the snap-fit ​​component 131 can be an existing snap hook or snap-fit ​​strip structure. When the snap-fit ​​component 131 is a snap hook, after the snap hook is inserted into the snap-fit ​​hole 121, the outer periphery of the snap hook is pressed by the wall of the snap-fit ​​hole 121 and can be inserted into the snap-fit ​​hole 121. Then it abuts against the end wall of the snap-fit ​​hole 121 so that the snap-fit ​​component 131 is not easy to loosen after it is snapped into the snap-fit ​​hole 121.

[0040] Of course, the snap-fit ​​131 can also be formed as a snap-fit ​​post or snap-fit ​​strip made of an elastic material. When an external force is applied to insert the snap-fit ​​131 into the snap-fit ​​hole 121, the snap-fit ​​131 will undergo elastic deformation to adapt to the size of the snap-fit ​​hole 121. This deformation allows the snap-fit ​​131 to enter the snap-fit ​​hole 121 smoothly. Once the snap-fit ​​131 is inserted into the snap-fit ​​hole 121, due to the elastic restoring force of the elastic material, the snap-fit ​​131 will try to return to its original shape so that the snap-fit ​​131 fits tightly against the inner wall of the snap-fit ​​hole 121 and is not easy to loosen.

[0041] Furthermore, the snap-fit ​​member 131 includes two snap-fit ​​arms 132 spaced apart, which are used to move closer to each other under force and move further apart under their own elastic force.

[0042] Based on the above structure, when it is necessary to snap the snap-fit ​​131 into the snap-fit ​​hole 121, the operator can gently press the two snap-fit ​​arms 132 on both sides. Since the two snap-fit ​​arms 132 are spaced apart, there is space for the two snap-fit ​​arms 132 to approach each other. When the two snap-fit ​​arms 132 approach each other, the two sides of the snap-fit ​​131 will narrow, making it easier for the snap-fit ​​131 to be inserted into the snap-fit ​​hole 121. After insertion, under the action of their own elastic stress, the two snap-fit ​​arms 132 will move away from each other and open outward to fit tightly against the inner wall of the snap-fit ​​hole 121, preventing the snap-fit ​​arms 132 from easily coming out of the snap-fit ​​groove, thereby achieving a stable snap-fit ​​function.

[0043] Specifically, the snap-fit ​​arm 132 can be made of a flexible material such as stainless steel or plastic, so that the snap-fit ​​arm 132 can be smoothly snapped into the snap-fit ​​hole 121 under pressure and pressed against the inner wall of the snap-fit ​​hole 121.

[0044] Furthermore, the snap-fit ​​arm 132 has a snap-fit ​​connector 133 protruding from its side. The snap-fit ​​connector 133 is used to be pressed against the inner wall of the snap-fit ​​hole 121 when it is inserted into the snap-fit ​​hole 121, so as to guide the two snap-fit ​​arms 132 to approach each other. The snap-fit ​​connector 133 is used to pass through the snap-fit ​​hole 121 and snap-fit ​​after the two snap-fit ​​arms 132 approach each other.

[0045] Specifically, as the two snap-fit ​​arms 132 are gradually inserted into the snap-fit ​​hole 121, the snap-fit ​​connector 133 protruding from its side will pass through the snap-fit ​​hole 121 under the top pressure of the inner wall of the snap-fit ​​hole 121. At this time, the snap-fit ​​arms 132 will return to their original shape under the action of their own elastic stress, that is, in an open state, so that the snap-fit ​​connector 133 abuts against the end wall of the snap-fit ​​connector 133. In this way, the snap-fit ​​connector 133 can be locked at the edge of the snap-fit ​​hole 121, preventing the snap-fit ​​arms 132 from coming out of the snap-fit ​​hole 121, making the structure more stable.

[0046] When it is necessary to disengage the snap-fit ​​arm 132 from the snap-fit ​​hole 121 again, simply apply external force to the snap-fit ​​arm 132 again, so that the two snap-fit ​​arms 132 are close to each other until the snap-fit ​​connector 133 can be disengaged from the snap-fit ​​hole 121. The entire disassembly and assembly process can be completed without the aid of external tools, making the operation more convenient.

[0047] Furthermore, the snap-fit ​​connector 133 is provided with a guide slope 1331, which slides with the inner wall of the snap-fit ​​hole 121 and is pressed by the inner wall of the snap-fit ​​hole 121 to guide the snap-fit ​​connector 133 to snap into or out of the snap-fit ​​hole 121.

[0048] Specifically, when the snap-fit ​​connector 133 begins to contact the snap-fit ​​hole 121, during the process of the snap-fit ​​connector 133 entering the snap-fit ​​hole 121, due to the sliding fit between the guide ramp 1331 and the snap-fit ​​hole 121, the snap-fit ​​connector 133 will not enter the snap-fit ​​hole 121 at its maximum size all at once. Instead, it will enter little by little under the guidance of the guide ramp 1331. This can reduce the resistance during the snap-fit ​​process and make the snap-fit ​​smoother.

[0049] When it is necessary to disengage the snap-fit ​​connector 133 from the snap-fit ​​hole 121, an outward force is applied to the snap-fit ​​connector 133. At this time, the inner wall of the snap-fit ​​hole 121 slides into the guide ramp 1331, guiding the snap-fit ​​connector 133 to move outward along the ramp direction, thereby enabling the snap-fit ​​connector 133 to disengage from the snap-fit ​​hole 121 smoothly.

[0050] Furthermore, a locking block 15 is provided on the outer periphery of the clamp body 10, and a locking groove 151 is provided on the locking block 15.

[0051] Specifically, when the external structure has protruding snap-fit ​​posts or snap-fit ​​strips or other snap-fit ​​structures, the outer periphery of the clamp body 10 also has a snap-fit ​​groove 151. At this time, the snap-fit ​​groove 151 can engage with the protruding structure on the external structure, so that the clamp body 10 can not only be connected to the external structure through the connector 14, but also engage with the external structure through the snap-fit ​​groove 151 on the snap-fit ​​block 15, so as to adapt to various types of external structures and make the application range of the clamp body 10 wider.

[0052] In addition, since there may be different requirements for the position and angle of the wire harness fixing, the positions of the clamp post and the connector 14 can be set at different positions on the outer periphery of the clamp body 10, so that the clamp body 10 can be fixed to the external structure at different angles and positions, providing more flexibility for the installation of the clamp.

[0053] More specifically, the slot 151 has an arc-shaped guide surface. When the external structure approaches the slot 151, the arc-shaped guide surface acts like a guide rail, which can effectively guide the protruding structures on the external structure (such as snap-fit ​​posts or snap-fit ​​strips) into the slot 151. Especially in the rapid assembly process on the automobile production line, workers may not be able to accurately align the buckle with the slot 151. The arc-shaped guide surface can compensate for this alignment error to a certain extent, making it easier for the protruding snap-fit ​​posts or snap-fit ​​strips to contact the slot 151 and slide in along the guide surface, reducing the resistance during the insertion process and making it easier for the external structure to engage with the slot 151.

[0054] Furthermore, the clamp body 10 has at least two through holes 16, and the walls of the at least two through holes 16 are provided with limiting ribs 161, which extend circumferentially along the through holes 16.

[0055] Specifically, space is a very valuable resource inside a car. By setting at least two through holes 16 in the clamp body 10 to fix multiple sets of wiring harnesses, the layout of the wiring harnesses can be made more compact. Multiple sets of wiring harnesses with different functions (such as engine control unit wiring harnesses, sensor wiring harnesses, etc.) can be arranged and fixed in an orderly manner through different through holes 16, avoiding the messy distribution of wiring harnesses, thereby saving space and facilitating the installation and maintenance of other components.

[0056] In addition, to prevent damage to the wire harness, a corrugated tube is usually wrapped around the outer periphery of the wire harness as a protective sleeve. Because the corrugated tube has a certain degree of flexibility, it may shift or interfere with other components during vehicle movement after being inserted into the insertion hole 16, thus damaging the wire harness. Therefore, in this embodiment, a limiting rib 161 is also provided on the inner wall of the insertion hole 16. When the corrugated tube passes through the insertion hole 16, the limiting rib 161 can hold the outer surface of the corrugated tube, preventing the corrugated tube from shifting within the insertion hole 16, ensuring that the fixed position of the wire harness remains unchanged, and making the structure more practical.

[0057] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
