I found an adapter in my junk box that goes from a BNC to something similar
to a male N type. It will not mate up to a female N connector.

A normal N male connector has the center that is just about even with the
shell that screws onto the female end. This connector has the male part
sticking out about 1/4 of an inch past the shell. It will fit the female N
connector except when I go to screw them together, there is not enough
threads to mate and make a good mechanical connection.

Anyone know what type of connector this is ?

It's an ordinary BNC to Male N adapter, where the dielectric has been
somehow mangled, causing the center shield, pin, and dielectric to get
pushed out. You might be able to disassemble the adapter and repair
it. Try pushing on the center pin on the N side of the adapter and
see if it moves back into the adapter. Some of the cheap connectors
from China are little better than junk and tend to fall apart with
little provocation.

Hint: Photos are useful for identifying strange connectors.
