Connection structure of circuit board and connecting device

摘要

An inexpensive connection structure of a circuit board and a connecting device is disclosed that allows easy connection/detachment of the connecting device to/from the circuit board. The connection structure includes a connecting device 100 electrically and mechanically connectable to a longitudinal end of a cold cathode fluorescent lamp 10 via an adapter 400, and a circuit board 300 electrically and mechanically connected with the connecting device 100. The connecting device 100 includes a locking piece 114. The circuit board 300 has a locking hole 310 for locking the locking piece 114. The locking hole 310 is a slot consisting of a wider hole 311 and a narrower hole 312 continuous with the wider hole 311. The locking piece 114 can be locked at a lip 312a of the narrower hole 312 by inserting the locking piece 114 into the wider hole 311 and sliding it from the wider hole 311 to the narrower hole 312.
