There's a lot of things like this, especially when the connector is commonly used for just one thing. One is "composite video" which at one point or another I have heard items on this list used interchangeably (though not always at the same time):
composite video
- RS-170
- monochrome video
- EIA-170
- NTSC
- black and white video
- CVBS
- B&W video
- RS-170A
- analog video
- PAL
- yellow RCA plug
- just plain "video"
These don't even all refer to the same thing, and some are definitely more correct than others, but all are used even by technical people.
Here's another one: "Amphenol connector", "Cannon connector" or "Molex connector". It's the same as saying "Ford car".
