Abstract
Description
Technical Field
[0001] This utility model relates to the field of grounding harness protection technology, and in particular to a protection device for grounding harnesses. Background Technology
[0002] In the fields of automobiles, industrial machinery, and outdoor power equipment, grounding harnesses are a key component of circuit systems, playing a crucial role in current return, potential equalization, and equipment grounding protection. Their connection stability directly determines the operational reliability and safety of the entire circuit system.
[0003] However, when grounding harnesses are used in high-vibration environments such as automotive engine compartments and the vibrating area around industrial machine tool spindles, traditional protection devices do not have effective anti-loosening structures. They rely solely on bolt tightening or the crimping tension of the terminals to maintain the connection. Long-term vibration can cause bolt threads to loosen and gaps to appear at the terminal crimping points, resulting in a significant increase in the contact resistance between the terminals and the equipment. This can lead to problems such as localized heating and unstable signal transmission, and in severe cases, it can cause circuit breaks, which seriously shortens the service life of the device.
[0004] Therefore, it is necessary to provide a protective device for grounding harnesses to solve the above-mentioned technical problems. Utility Model Content
[0005] This utility model provides a protective device for grounding wire harnesses, which solves the problem that traditional devices may cause the terminal connection to loosen when exposed to long-term vibration environments.
[0006] To solve the above-mentioned technical problems, this utility model provides a protective device for grounding wire harnesses, comprising: a device body, an auxiliary structure, a fixing structure, and a horizontal plate on the device body; the auxiliary structure includes an auxiliary block, a fixing block installed inside the auxiliary block, a limiting slider installed inside the fixing block, a limiting block installed on the limiting slider, a first elastic element for limiting the slider's reset inside the fixing block, a rotating bearing installed on the horizontal plate, a rotating gear installed on the rotating bearing, a vertical groove and a nut groove on the rotating gear, a torsion block installed on the auxiliary block, the torsion block being fixedly connected to the inner ring of the rotating bearing, and the rotating gear being fixedly connected to the inner ring of the rotating bearing.
[0007] Preferably, the fixing structure includes a fixed base plate, a guide rod is installed inside the fixed base plate, a connecting block is slidably connected to the guide rod, and a wire fixing block is installed on the connecting block.
[0008] Preferably, a guide groove is provided on the fixed base plate, the connecting block is slidably connected to the guide groove, and a second elastic element for resetting the connecting block is arranged around the guide rod.
[0009] Preferably, the main body of the device is provided with terminals, the terminals are equipped with connectors, and the connectors are provided with inner grooves.

[0011] Preferably, the main body of the device is provided with a wire harness, and the wire harness is surrounded by an insulating layer.
[0012] Preferably, the insulating layer is surrounded by a protective shell.
[0013] Compared with related technologies, the protective device for grounding wire harness provided by this utility model has the following beneficial effects: This utility model provides a protective device for grounding wire harnesses. When using this device, during terminal connection, the torsion block can be rotated, which drives the rotating gear to rotate. As the rotating gear rotates, the nut rotates, completing the installation. If the nut becomes loose due to vibration or other factors, the limiting block will restrict the rotation of the teeth on the rotating gear, thereby preventing the fixed end from becoming loose. This device adds a function to prevent terminal loosening. The anti-loosening function can firmly fix the connection between the terminal and the vehicle body. Even under equipment vibration and bumps, such as when a car is driving or a machine is running, it can maintain low resistance conduction, avoiding equipment failure caused by poor contact, thereby extending the service life.
