Description

Technical Field

[0001] This disclosure relates to an electrical power connection device, and more particularly to a laser electrical power connection device. Background Technology

[0002] In existing electronic devices or automated machinery, various internal components (e.g., sensors, actuators, communication modules, and control circuits) require power via wires or cabling. However, wired wiring often presents the following problems:

[0003] 1. Large space occupation: The wiring needs to be routed according to the structure, which limits the structural design, especially in narrow or enclosed structures.

[0004] 2. Complex assembly: The wires need to be soldered, fixed or plugged in, which increases assembly time and cost.

[0005] 3. Reliability issues: After long-term use, the wires may break or short-circuit due to friction, bending, aging, or moisture.

[0006] 4. Design limitations for moving components: If components need to rotate or slide, traditional wired power supply is limited by the lifespan of rotary joints or flexible cables.

[0007] While existing wireless power transmission technologies (e.g., electromagnetic induction or radio frequency coupling) exist, their efficiency is susceptible to distance and coupling alignment issues, making them unsuitable for all applications. Therefore, a solution must be developed that combines high efficiency, directionality, structural simplicity, and power supply capability. Utility Model Content
