[0002] Electromagnetic compatibility (EMC) testing is a crucial method for evaluating the ability of electronic equipment to operate normally in electromagnetic environments. It includes electromagnetic interference (EMI) testing and electromagnetic immunity (EMI) testing to ensure that the equipment does not interfere with other devices when transmitting and receiving electromagnetic signals, and also resists external electromagnetic interference. In modern electronic equipment, EMC is a vital indicator for ensuring equipment reliability and safety.

[0003] A typical electromagnetic compatibility (EMC) test cable bundle fixing splitter consists of a placement plate, a docking mechanism, and connection ports. During use, the placement plate is used to support and carry the entire device and cables, providing a stable foundation. The docking mechanism uses bolts, nuts, and other components to clamp and fix the cables. The connection ports are used to connect external devices and cables to achieve signal transmission and distribution, ensuring the smooth progress of the test.

[0004] However, in some existing devices, the design of the docking mechanism cannot effectively secure the docking part after the threaded connection, which makes the cable easy to fall off during the test. This falling off phenomenon not only affects the accuracy and stability of the test data, but also causes cable damage and test interruption, seriously affecting test efficiency and equipment reliability. To solve the above problems, a cable bundle fixing splitter for electromagnetic compatibility testing is proposed. Utility Model Content

[0030] 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.

[0031] Reference Figure 2 and Figure 4 An embodiment of this utility model is provided: a cable bundle fixing splitter for electromagnetic compatibility testing, including a base plate 1, a fixing mechanism 2 and a cable management mechanism 3 provided on the top of the base plate 1.

[0032] The fixing mechanism 2 includes multiple bolts 21, designed to provide good connection capability. The bolts 21 are externally fixedly connected to the top of the base plate 1. The bolts 21 are externally threaded to a mating assembly, which includes multiple nuts 22. The nuts 22 are threaded onto the outside of the bolts 21, allowing for cable connection and fixing. The nuts 22 are externally threaded to the outside of the bolts 21, and multiple slots 23 are formed on the outside of the nuts 22, designed to provide good locking capability. A clamping plate 28 is externally fixedly connected to the inside of the slots 23. Multiple placement boxes 24 are fixedly connected to the top of the base plate 1, designed to provide good placement space. A pressing assembly is fixedly connected inside the placement box 24, and the pressing assembly includes multiple guide posts 25. The support enables the guide post 25 to provide good guiding capability. Multiple guide posts 25 are externally fixedly connected to the inside of the placement box 24. Compression springs 26 are respectively sleeved on the outside of the multiple guide posts 25. The guiding capability of the guide posts 25 can prevent the compression springs 26 from shifting during compression and tension. The sliding block 27 is externally fixedly connected to the outside of the compression springs 26. The external of the compression assembly is fixedly connected to the sliding block 27. The sliding space provided by the placement box 24 allows the sliding block 27 to slide smoothly. A retaining plate 28 is fixedly connected to one side of the sliding block 27. When the nut 22 is connected to the bolt 21, the design of the retaining plate 28 can slide outside the retaining groove 23 through the extension and retraction capability of the compression springs 26 to fix the bolt 21 and prevent it from falling off during use.

[0033] Reference Figure 1 and Figure 3 The cable management mechanism 3 includes multiple adjusting rods 31, designed to provide good telescopic capability. The multiple adjusting rods 31 are externally fixedly connected to the top of the base plate 1. The output ends of the multiple adjusting rods 31 are fixedly connected to support boxes 32. The telescopic capability of the adjusting rods 31 can drive the support boxes 32 to telescopically extend and retract. The multiple support boxes 32 are internally fixedly connected to guide rods 34, designed to provide good guiding capability. The multiple guide rods 34 are externally fitted with return springs 35. Each support box 32 has two return springs 35 and guide rods 34 installed inside, so that they can be relatively reset after compression. The multiple return springs 35 are externally fixedly connected to sliders 33. When the return springs 35 reset, they can drive the sliders 33 to move. The multiple sliders 33 are externally fixedly connected to locking blocks 36. By the compression of the return springs 35, the sliders 33 can slide and move closer to each other within the support box 32, causing the locking blocks 36 to move closer to each other.

[0034] Working Principle: In use, the cable bundle is first placed in the fixing mechanism 2 on the base plate 1. By tightening the nut 22 onto the outside of the bolt 21, a tightening force is generated between the nut 22 and the bolt 21. Since the nut 22 has a slot 23 on its outside, and a clamping plate 28 is fixedly connected inside the slot 23, when the nut 22 is tightened, the clamping plate 28 applies pressure to the cable bundle, firmly clamping it between the clamping plates 28, thus fixing the cable bundle. Simultaneously, the guide post 25 provides stable guidance for the compression spring 26, preventing it from shifting during compression and tension. The extension and retraction capacity of the compression spring 26 allows the sliding block 27 to move smoothly within the sliding space provided by the placement box 24. When the nut 22 is connected to the bolt 21, the clamping plate 28 on one side of the sliding block 27 slides along the slot 23 under the push of the compression spring 26, further fixing the bolt 21 and ensuring that the nut 22 and bolt 21 will not fall off during use, thus ensuring the stable fixing of the cable bundle.

[0035] When organizing cables, the position of the support box 32 is first adjusted by the telescopic capability of the adjusting rod 31 to accommodate cables of different lengths and diameters. The telescopic movement of the adjusting rod 31 moves the support box 32, allowing it to be positioned according to the cable arrangement requirements. The guide rod 34 inside the support box 32 provides a stable sliding guide for the slider 33. When the cable needs to be secured, the return spring 35 is compressed, causing the slider 33 to slide along the guide rod 34 within the support box 32, bringing the locking blocks 36 closer together. The closer proximity of the locking blocks 36 clamps the cable, achieving both cable securing and cable separation. When the cable needs to be released, the return spring 35 is pulled, pushing the slider 33 to slide in the opposite direction along the guide rod 34, causing the locking blocks 36 to move away from each other, thus releasing the cable. Through the elastic action of the return spring 35, the slider 33 and locking blocks 36 can automatically return to their initial positions, preparing for the next cable securing operation.

[0036] 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.
