Abstract: A connector is provided to make terminal fittings unlikely to be struck against external matter. The connector is for use with a circuit board in which terminal fittings are bent downward after being pulled backward of a connector housing 1 so as to be connectable with a circuit board 5, protection walls including an upper protection wall 10 extend behind the connector housing 1 to surround the terminal fittings 2 lest the terminal fittings 2 should project. Thus, the protection walls prevent the terminal fittings 2 from being directly struck by an external matter. Furthermore the invention relates to an improved method for producing a connector.
