Hi just trying to get my head around all these different plugs and connectors and saw this term used on sbiddle's "A beginners guide to DIY structured cabling in a new house - Part II". Hunted a picture on google and it looks like a RJ45 socket?
I've always understood that Krone connections were those types like the insides of phone jacks, you know where you use a little plastic thing to push the wire into a slot (or a professional tool that does the same job, but the retail chains love them little plastic things!)
I could be wrong though - I don't care about these technical terms much
Krone is a Company that specialises in termination equipment, a lot of Cat5 and such so termination of cat 5 cables can be done to a Krone Jack which is where you plug your RJ45 connector into, the plate that covers this may be called a Krone plate, there are different types of companies and connectors that do the same job, Krone was just one of the first and a common name in the industry
krone is also the tool used with telecom BT sockets and some RJ45 wall plates - most use a 110 tool which is not really interchangable with the krone tool, but the krone will get the wire in eventually with enough cursing and swearing. The terminals were mainly used on krone frames which are rows of slot terminals used to patch things before people started to do structured cabling which is why they chose them for the backs of BT sockets since all telco people had the tool already, whereas the 110 tool was not as common.
The common cheap wall sockets are whats called keystone, there are many things available to go into a keystone opening, like speaker binding posts, RCA, Svideo, fiber etc, but noone really uses them in NZ.
