Description

Technical Field

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

[0002] In today's electrical equipment, automotive manufacturing, aerospace, and various industrial production fields, the rational layout and secure fixing of cable harnesses play a crucial role. With continuous technological advancements, the functions of various devices are becoming increasingly complex, the number of cables involved is constantly increasing, and the wiring environment is becoming more diverse and demanding. In the past, simple ropes or basic clips were used to bind cable harnesses, but these methods are insufficient to meet the high precision and high reliability requirements of modern equipment for cable fixing.

[0003] When using traditional cable harness clamps, first arrange the cable harness to ensure that the cables are neatly arranged. Then, put the metal cable harness clamp on the appropriate position of the cable harness. Use a screwdriver to turn and tighten the screw to adjust the metal cable harness clamp. During the tightening process, pay attention to applying force evenly so that the clamp gradually tightens and provides uniform fastening force to fix the cable.

[0004] However, in the existing technology, traditional wire harness clamps are usually fixed with screwdrivers and screws, which requires a lot of tools and parts for installation and disassembly, and there is also a risk of loss. The installation and disassembly are cumbersome and inefficient. Therefore, a new type of cable harness clamp is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a cable harness clamp, which aims to improve the problem of low efficiency caused by the cumbersome installation and disassembly of cable harness clamps in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cable harness clamp includes an upper fixing ring and a lower fixing ring. Upper connecting plates are fixedly connected to both sides of the upper fixing ring, and lower connecting plates are fixedly connected to both sides of the lower fixing ring. A rotating rod is rotatably connected inside the upper connecting plate, and multiple conical clips are fixedly connected to the outside of the rotating rod. The conical clips have internal slots. Multiple locking strips are fixedly connected inside the lower connecting plate. A reset assembly for reversing the rotation of the rotating rod is provided at the top of the rotating rod. A fixing assembly for contacting and pressing irregularly shaped cables is provided inside the upper fixing ring.

[0008] As a further description of the above technical solution:

[0009] The outer surface of the conical card contacts the outer surface of the card strip, and the outer surfaces of the plurality of conical cards are slidably connected to the interior of the lower connecting plate.

[0010] As a further description of the above technical solution:

[0011] The reset assembly includes a knob, the bottom of which is fixedly connected to the top of the rotating rod.

[0012] As a further description of the above technical solution:

[0013] The rotating rod is fitted with a coil spring. One end of the coil spring is fixedly connected to the top of the upper connecting plate, and the other end of the coil spring is fixedly connected to the bottom of the knob.

[0014] As a further description of the above technical solution:

[0015] The interior of the slot is in contact with the exterior of the card strip, and the slot is rectangular in shape.

[0016] As a further description of the above technical solution:

[0017] The fixing assembly includes a rotating screw, the external thread of which is connected to the inside of the upper fixing ring, an arc-shaped plate is rotatably connected to the bottom of the rotating screw, and a nut is fixedly connected to the top of the rotating screw.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, the rotating rod slides into the interior of the lower connecting plate. At this time, the conical card outside the rotating rod is an elastic cone shape. After contacting the card strip, it deforms, realizing a progressive fastening operation, which is convenient and quick to install. Rotating the knob drives the rotating rod and the conical card to rotate, so that the empty groove is aligned with the card strip, and then sliding off for quick disassembly, improving the efficiency of installation and disassembly and improving portability.

[0020] 2.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0028] Reference Figures 1 to 3 This utility model provides an embodiment of a cable harness clamp, comprising an upper fixing ring 1 and a lower fixing ring 2. The upper fixing ring 1 is made of stainless steel with certain strength and toughness, and has a semi-circular ring structure. Upper connecting plates 3 are fixedly connected to both sides of the upper fixing ring 1. The upper connecting plates 3 are rectangular plastic sheets, playing a key role in connection and support. Lower connecting plates 4 are fixedly connected to both sides of the lower fixing ring 2. The shape and size of the lower connecting plates 4 are adapted to the upper connecting plates 3, and they are also rectangular plastic sheets. A rotating rod 5 is rotatably connected inside the upper connecting plate 3. The rotating rod 5 is cylindrical and slides into the interior of the lower connecting plate 4 for fixation. Multiple conical clips 8 are fixedly connected to the outside of the rotating rod 5. The conical clips 8 are elastic cones with carefully designed tapers to ensure smooth passage when inserted into the lower connecting plate 4 and to produce appropriate deformation after contact with the clip strip 10, thereby achieving progressive tightening. The conical clips 8 have internal openings... The slot 9 provides a possibility for rotational reset. Multiple locking strips 10 are fixedly connected inside the lower connecting plate 4. These locking strips 10 are slender strips and are evenly distributed inside the lower connecting plate 4. Their material has good wear resistance and rigidity and can withstand a certain amount of friction and pressure. The top of the rotating rod 5 is provided with a reset component for reversing the rotation of the rotating rod 5. The upper fixing ring 1 is provided with a fixing component for contacting and pressing the irregular cable. The outside of the conical card 8 contacts the outside of the locking strip 10, thereby realizing a progressive fastening function. The outside of the multiple conical cards 8 are slidably connected inside the lower connecting plate 4.

[0029] Reference Figures 2 to 3 The reset assembly includes a knob 6, the bottom of which is fixedly connected to the top of the rotating rod 5. The knob 6 is made of high-strength engineering plastic and is in the shape of a round flat disc with a protrusion on the top for easy gripping and rotational force by the operator. A coil spring 7 is sleeved on the outside of the rotating rod 5. One end of the coil spring 7 is fixedly connected to the top of the upper connecting plate 3, and the other end is fixedly connected to the bottom of the knob 6. The reaction force of the coil spring 7 drives the rotating rod 5 to rotate and reset for easy use next time. The inside of the slot 9 contacts the outside of the clip 10. The slot 9 is rectangular in shape. The contact between the slot 9 and the clip 10 allows the conical card 8 to slide and release the fixed state.

[0030] Reference Figure 1 and Figure 4 The fixing assembly includes a rotating screw 11, whose external thread is connected to the inside of the upper fixing ring 1. The rotating screw 11 can stably rotate helically inside the upper fixing ring 1, and its position in the vertical direction can be precisely adjusted during rotation, thereby achieving height control of the subsequent structure to accommodate irregularly shaped cables of different thicknesses and shapes. An arc-shaped plate 12 is rotatably connected to the bottom of the rotating screw 11. This arc-shaped plate better conforms to the top contour of the irregularly shaped cable, increasing the contact area and thus dispersing pressure and preventing excessive local compression of the cable. A nut 13 is fixedly connected to the top of the rotating screw 11, allowing tools to be used to rotate the rotating screw 11 more effectively.

[0031] Working principle: First, the operator places the upper fixing ring 1 on top of the lower fixing ring 2, aligning the two rotating rods 5 with the holes inside the lower connecting plate 4, and slides the rotating rods 5 into the lower connecting plate 4. At this time, because the conical card 8 outside the rotating rod 5 is an elastic cone, it deforms after contacting the locking strip 10, realizing a progressive tightening operation, which is convenient and quick to install. Second, during disassembly, by rotating the knob 6, the rotating rod 5 is rotated, which in turn drives the coil spring 7 to rotate and stretch, accumulating elastic force, so that the slots on the conical card 8 are formed. Alignment is achieved between the upper fixing ring 1 and the lower fixing ring 2. At this point, the upper fixing ring 1, the two connected rotating rods 5, and the conical card 8 are slid out from the inside of the upper connecting plate 3 to complete disassembly. Finally, the reaction force of the coil spring 7 drives the rotating rod 5 to reverse, completing the rotation reset for easy use next time. The unique structural design eliminates the need for complicated tools and cumbersome operating steps. Simply align the upper fixing ring 1 with the lower fixing ring 2 and insert the rotating rod 5. The elastic deformation of the conical card 8 can quickly achieve fastening. Disassembly can be achieved by rotating the knob 6, which greatly improves the efficiency of installation and disassembly.

[0032] Finally, when clamping and fixing the cable harness, when encountering irregularly shaped cables, the upper fixing ring 1 and the lower fixing ring 2 are used to fix the cable in both left and right directions. At this time, by using a tool to rotate the nut 13, the rotating screw 11 is driven to rotate in a spiral motion, thereby driving the arc plate 12 to generate downward pressure, so that the arc plate 12 contacts the top of the irregularly shaped cable, forming clamping and fixing in multiple directions, increasing the fixing effect. Through the initial fixing of the cable in the left and right directions by the upper fixing ring 1 and the lower fixing ring 2, combined with the adjustable arc plate 12 applying pressure from the top, the irregularly shaped cable is accurately and stably clamped in multiple directions, which greatly improves the reliability of cable fixing.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
