Description

Technical Field

[0001] This utility model relates to the field of wire and cable fixing clip technology, specifically a wire and cable fixing clip structure for wire harnesses that prevents pulling. Background Technology

[0002] With the increasing use of electronic and electrical components, wire harnesses are also being used more and more. Wire harnesses may have long spans in or between electrical components. In order to ensure the reliability of power or signal transmission by wire harnesses during long-term operation or vibration of the machine, it is necessary to arrange and fix wire harnesses with long spans.

[0003] Traditional cable clamps are prone to cable detachment due to vibration or external force, the clamping force is relatively unstable, and the stress concentration at the fixing point can easily lead to internal cable breakage after long-term use. In addition, they cannot be adapted to cables of different diameters, which limits their use. Therefore, a cable clamp structure for wire harnesses that is not pulled is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a wire harness anti-pull cable fixing clip structure to solve the problem that the traditional cable fixing clip mentioned in the background art is relatively limited in use. Therefore, a wire harness anti-pull cable fixing clip structure is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wire harness anti-pull cable fixing clip structure, including an upper cover and a lower cover, wherein auxiliary components are provided on the outer side of the upper cover and the lower cover;

[0006] The auxiliary components include connectors, silicone pads, bases, first protrusions, connecting rods, second protrusions, springs, buttons, bolts, bolt holes, backing and screw holes;

[0007] The upper cover and the lower cover are both fixedly connected to the outer side of the connector. The inner side of the upper cover and the lower cover is provided with a silicone pad. The base is fixedly connected to the outer wall of the lower cover. The first protrusion is fixedly connected to the mating part of the upper cover. The connecting rod is fixedly connected to one side of the first protrusion. The second protrusion is fixedly connected to the mating part of the lower cover. The spring is sleeved on the outer side of the connecting rod. The button is fixedly connected to one end of the second protrusion. The bolt is provided on the surface of the button. The bolt hole is opened on the surface of the lower cover. The backing is provided on the surface of the base. The screw hole is opened on one side of the base.

[0008] Preferably, both the upper cover and the lower cover have anti-slip textures formed on their surfaces, and the anti-slip textures have a serrated structure.

[0009] Preferably, the second protrusion is slidably connected to the connecting rod, and the connecting member has an outwardly expanding flared structure.

[0010] Preferably, the two ends of the spring are fixedly connected to the connecting rod and the button respectively, and the spring in a telescopic state is used to assist the connecting rod in moving.

[0011] Preferably, the bolt hole is used for threaded connection of the bolt, and the bolt in the tightened state is used to lock the movement of the connecting rod.

[0012] Preferably, the screw hole cooperates with the backing to fix the upper cover and the lower cover to the surface of the electrical equipment.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This auxiliary component allows the upper and lower covers to limit and clamp the cable, and then fixes the upper and lower covers and the clamped cable to the electrical equipment. It can be adapted to cables of different types. By setting the anti-slip texture with a serrated structure, the friction of the contact surface is increased, making the cable less prone to displacement in a vibration environment. At the same time, the serrated angle design avoids stress concentration and cable sheath damage. The silicone pad achieves a balanced buffering and support effect, protecting the clamped cable. Furthermore, the flared connector effectively distributes the bending stress of the cable, thereby effectively improving the anti-pull performance through the above structure.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution for a wire harness anti-pull cable fixing clip structure: a wire harness anti-pull cable fixing clip structure, including an upper cover 1 and a lower cover 2, with auxiliary components 3 provided on the outer side of the upper cover 1 and the lower cover 2;

[0021] The auxiliary component 3 includes a connector 301, a silicone pad 302, a base 303, a first protrusion 304, a connecting rod 305, a second protrusion 306, a spring 307, a button 308, a bolt 309, a bolt hole 3010, a backing 3011, and a screw hole 3012.

[0022] Connectors 301 are fixedly connected to the outer sides of both the upper cover 1 and the lower cover 2. Silicone pads 302 are provided on the inner sides of both the upper cover 1 and the lower cover 2. The base 303 is fixedly connected to the outer wall of the lower cover 2. The first protrusion 304 is fixedly connected to the mating point of the upper cover 1. The connecting rod 305 is fixedly connected to one side of the first protrusion 304. The second protrusion 306 is fixedly connected to the mating point of the lower cover 2. The spring 307 is sleeved on the outer side of the connecting rod 305. The button 308 is fixedly connected to one end of the second protrusion 306. The bolt 309 is provided on the surface of the button 308. The bolt hole 3010 is opened on the surface of the lower cover 2. The backing 3011 is provided on the surface of the base 303. The screw hole 3012 is opened on one side of the base 303.

[0023] Please refer to this carefully. Figure 1 Both the upper cover 1 and the lower cover 2 have anti-slip textures 4 formed on their surfaces, and the anti-slip textures 4 have a serrated structure.

[0024] In this embodiment: by setting the anti-slip texture 4 with a serrated structure, the friction of the contact surface is increased, making the cable less prone to displacement under vibration. At the same time, the serrated angle design avoids stress concentration that could cause damage to the cable sheath.

[0025] Please refer to this carefully. Figure 2 The second protrusion 306 is slidably connected to the connecting rod 305, and the connecting piece 301 has an outwardly expanding flared structure.

[0026] In this embodiment: Since the connector 301 has an outwardly expanding flared structure, it effectively distributes the bending stress of the cable, and the above structure effectively improves the anti-pull performance.

[0027] Please refer to this carefully. Figure 3 The two ends of the spring 307 are fixedly connected to the connecting rod 305 and the button 308 respectively, and the spring 307 in the telescopic state is used to assist the connecting rod 305 in moving.

[0028] In this embodiment: by loosening the upper cover 1 by hand, the spring 307 in the reset state drives the connecting rod 305 to move, and the moving connecting rod 305 drives the upper cover 1 to move closer to the lower cover 2.

[0029] Please refer to this carefully. Figure 3 Bolt hole 3010 is used for threaded connection of bolt 309, and bolt 309 in the tightened state is used to lock the movement of connecting rod 305.

[0030] In this embodiment: the bolt 309 is threaded into a bolt hole 3010, so that the bolt 309 in the tightened state is used to lock the movement of the connecting rod 305, and the distance between the upper cover 1 and the lower cover 2 is fixed.

[0031] Please refer to this carefully. Figure 4 The screw hole 3012 and the backing 3011 are used to fix the upper cover 1 and the lower cover 2 to the surface of the electrical equipment.

[0032] In this embodiment: the lower cover 2 is attached to the surface of the electrical equipment by the backing 3011, and then screws are used to connect it to the screw hole 3012 to position the lower cover 2 on the surface of the electrical equipment, thereby completing the installation of the upper cover 1, the lower cover 2 and the clamped cable.

[0033] Working principle: First, place the cable in the clamping area between the upper cover 1 and the lower cover 2. Then, loosen the upper cover 1 by hand, so that the spring 307 in the reset state drives the connecting rod 305 to move. The moving connecting rod 305 then moves the upper cover 1 closer to the lower cover 2. The upper cover 1 and the lower cover 2 cooperate to clamp the cable. Then, the bolt 309 is threaded into a bolt hole 3010. The bolt 309 in the tightened state is used to lock the movement of the connecting rod 305, thus fixing the distance between the upper cover 1 and the lower cover 2. The upper cover 1 and the lower cover 2 then limit and clamp the cable. Then, fix the upper cover 1, the lower cover 2 and the clamped cable to the electrical equipment. The lower cover 2 is glued to the surface of the electrical equipment by the backing 3011. Then, the screw is threaded into the screw hole 3012 to position the lower cover 2 on the surface of the electrical equipment. Thus, the installation of the upper cover 1, the lower cover 2 and the clamped cable is completed.

[0034] By setting the anti-slip texture 4 with a serrated structure, the friction of the contact surface is increased, making the cable less prone to displacement under vibration. At the same time, the serrated angle design avoids stress concentration and cable sheath damage. By setting silicone pads 302 on the inner side of both the upper cover 1 and the lower cover 2, the effect of balanced buffering and support is achieved, protecting the clamped cable. Since the connector 301 has an outwardly expanding flared structure, it effectively distributes the bending stress of the cable. The above structure effectively improves the anti-pull performance.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
