Wire-to-board connector

A wire-to-board connector comprising:

• a first terminal attached to an electric wire;
• and
• a second terminal mounted on a substrate, wherein the first and second terminals are formed of metal, and the electric wire is electrically connected to the substrate by fitting the first terminal with the second terminal, and wherein
• the second terminal comprises an accommodating section formed into a tubular shape,
• the first terminal comprises an insertion section to be inserted into the accommodating section,
• the insertion section is provided with a claw section and the accommodating section is provided with an engaging section, and
• through an insertion of the insertion section into the accommodating section, the claw section is engaged with the engaging section and the first terminal is thereby fitted with the second terminal,
• wherein the insertion section comprises a cantilever-shaped lock spring strip formed between a pair of mutually-opposed side plates, the claw section is formed in the cantilever-shaped lock spring strip, and the cantilever-shaped lock spring strip is formed in a place closer to one of the pair of side plates than to the other side plate, and a key insertion gap is formed between the lock spring strip and the other side plate.
