They look like insulation-displacement connectors. Specifically the "tuning fork" or "U contact" types. Please see the figures in the links. They can be put in many punch-down blocks. The longer pieces may be the male pin-bar to be used for high retention (see the Google patent for an example of this). They look like the ones typically used communications/Internet splitting (as in an office setting where there are hundreds of Ethernet lines being routed).

The size and shape of the connector you referenced is not an exact match. I have added some better photos to the listing.

Those are gold plated contact inserts for Hubble style connectors. if you look at the round receptacle this is what they are made for.

Hello, these are a lot smaller then the referece link you provided, do you think they go to something else?

Double sided key lock tumblers, mostly used in automotive applications.


Mechanic for over 20 years, rebuilt, many double sided key locks.

Can you find these online? I'm having trouble verifying your answer because I can't find any "double sided key lock tumblers" that look like these. Thank you.

These are blades for IDC Insulation Displacing Connectors or IPC Insulation Piercing Connectors. There are numerous manufacturers and applications in the communications & electronics industries. They are common in punch down blocks for telephone junctions and ribbon cable connections.

Thanks for the contribution but I can't locate any that resemble the ones we have for sale. I see several that have the same general appearance but not these specifically. Could you possibly find a closer match?
