Both are banana plugs - just different manufacturer's=20 implementation. There are other styles as well. Note that banana=20 plugs are now also known as 4mm plugs - make sure that you search for=20 both names. I do *NOT* like version (A) that you showed - I find that the spring=20 contact becomes unreliable on the plug's shaft when they get=20 old. That is: the connection between the spring and the plug shaft=20 becomes unreliable. Johnson makes reliable banana plugs - my all-time favorites are from=20 Johnson because they use an extremely-reliable solderless connection=20 to the wire / test lead. Part number 108-0303-001 for=20 black.=20 Both Digikey and Newark have lots of different styles available. dwayne At 09:59 AM 7/23/2013, veegee wrote: >I know this is a banana plug [connector A]: >http://www.muellerelectric.com/images/BU00249LG.jpg > >But what type of connector is this [connector B]: >http://www.vhaudio.com/images/wbt-0600.jpg > >Note that in [connector B], the plug is a shaft split into a (+).

Searching "banana plug" yields [connector A].
