AI Technical Summary

Technical Problem

During the power cord bend test, the existing SR-91 power cord clamp exhibited a wire breakage rate of 50-100%, failing to meet the safety standard requirement of a wire breakage rate of ≤10%. The wire breaks were concentrated at the base of the clamp.

Method used

A bending-resistant power cord clamp structure is designed. By setting reinforcement rings and ribs on the socket connector and the clamp housing, and adding protective corners at the corners, the force distribution is optimized. When the power cord is bent, the force point is transferred from the root to the middle, thereby increasing the bending radius.

Benefits of technology

Improve the bending resistance of the line card by at least 60%, ensure the product's appearance and structure remain unchanged, and meet the wire breakage rate requirements of safety standards.

[0002] The power cord clamp structure can fix the power cord to prevent it from moving or falling off, especially in situations where the power cord position needs to be kept stable or it needs to be protected from external interference. The power cord clamp structure can be used to group the power cords in layers, making the lines neat and beautiful, with good heat dissipation, and solving the problem of various cables crossing and affecting each other during construction. In addition, the power cord clamp structure can also disperse the heavy pressure borne by the cable as much as possible, ensuring the service life and safety cycle of the cable, and eliminating fire hazards.

The breakage point was typically located at the base of the clamp. Utility Model Content

[0005] The present invention aims to provide a bend-resistant power cord clamp structure to address the problem with the existing SR-91 power cord clamp, as discussed in the background art.
