Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a structural component for a lamp holder. Background Technology

[0002] As the core structural component in lighting equipment that enables power transmission and bulb fixation, the performance of lamp holders directly affects the safety, stability, and ease of use of the lighting system. In existing lamp holders, the wiring holes mostly adopt a blind hole design, with a closed internal space and fixed depth. Because blind holes lack space for redundant wire length, the metal core of the wire must be pre-cut to a specification suitable for the depth of the blind hole before wiring. If the core length is too long, it is prone to bending and piling up inside the blind hole after insertion, resulting in incomplete wire placement or poor contact at the terminals. If the core length is too short, insufficient contact between the core and conductive components can easily occur, leading to unstable power supply or even the risk of open circuit. Therefore, actual wiring is cumbersome and has a low tolerance for error, not only reducing installation efficiency but also increasing the potential for malfunctions due to improper length matching.
