[0002] When the loader is working, the bucket is frequently lifted and lowered, and the machine body bounces on rough roads, causing the overall structure to vibrate violently. Under the continuous mechanical impact, the signal cable connector and the sensor interface are easily loose and disconnected, causing the signal to be interrupted or intermittent, resulting in electronic scale reading jumping, zero error, seriously affecting the measurement accuracy and stability, and interfering with the normal material loading process control. At present, although there are some attempts to protect the cable in the industry, the results are not satisfactory. Some methods only use a cable tie to fix the cable, which is difficult to resist long-term and high-intensity shaking impact, and the protection is invalid after the cable tie is aged and broken.
