I don't think a poor connection like you had there will blow a fuse. I think a poor connection will cause increased resistance which causes a voltage drop so less current flow so the fuse won't blow. A short circuit on the other hand which is where a power wire comes in contact with a ground before it goes through the load will cause increased current flow because a short is basically removing the resistance of the load so it's the opposite of a poor connection. So way more current flows which blows the fuse. That'd explain why your fuse didn't blow.
