Description

Technical Field

[0001] This invention relates to the technical field of cable breakage protection devices, and in particular to a cable bending shock-resistant and leakage-proof protection device. Background Technology

[0002] A cable is a composite wire harness product used to transmit electrical energy, signals, or data, consisting of one or more insulated cores (conductors and their insulation layers) and their respective possible shielding layers, fillers, protective layers, and outer sheaths. During cable laying, considering the effects of thermal expansion and contraction, the cable is bent at intervals to prevent breakage due to winter shrinkage. However, this method still has drawbacks. For example, if the cable is rigidly fixed at the bends, it cannot contract properly, leading to breakage. During normal use, cables encounter various conditions that cause vibration, resulting in frequent contact between the cable and the fixing devices, potentially causing cable breakage or damage to the fixing devices, thus affecting the cable's lifespan. Summary of the Invention

[0003] The purpose of this invention is to provide a cable bending shockproof and leakage protection device in order to solve the above-mentioned problems.
