Title:
CIRCUIT BOARD FIXING STRUCTURE AND LIGHT RADIATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/182190
Kind Code:
A1
Abstract:
Provided is a small-sized circuit board fixing structure that allows the easy replacement of a circuit board on a base. This circuit board fixing structure for fixing a circuit board to a surface of a base comprises: a positive pattern and a negative pattern formed on the surface of the circuit board to supply power to the circuit board; a pair of first through-holes passing through the circuit board from the positive pattern and the negative pattern, respectively; a pair of second through-holes passing through the base vertically so as to interconnect with the first through-holes; a pair of electrode members respectively inserted through the second through-holes; and a pair of fixing members engaged with the respective electrode members to fix the circuit board to the base. Each electrode member has: an electrode terminal extending along the second through-hole; and an insulating member that is arranged to cover the outer periphery of the electrode terminal, that insulates the electrode terminal from the base, and that restricts the rotation of each electrode member with respect to the second through-hole. When each fixing member and each electrode member are engaged, each of the positive electrode pattern and the negative electrode pattern is electrically connected to each electrode terminal with each fixing member therebetween.
