Yes, but this scenario is a bit different. If you ask a connector factory to custom-make you a connector it's common that they are allowed to add it to their catalogue, though you can of course stipulate something else in the contract.
You'll see this in the electronics markets in Shenzhen for example... they still have a lot of the connectors and switches from MP3 players, which I believe was one of the early boom industries in the region.
