Post office crimps?

Feb 17, 2012 5 Replies

Does anyone know what the crimps telephone engineers use to join wires together in roadside boxes are called?



Or where to get some, and a crimping tool?



They are blue, about 22 by 7 by 3 mm with one end rounded and one end open for the wires to go in, and sometimes if a repairman has been working you can see a few lying around on the pavement.



Thanks,

Are these similar to what you are looking for:

Sorry for the messy link. Go to amazon.co.uk and use these words for search: telepnone wire cable splice

Generically they are IDC connectors, "insulation displacement connectors" and the installation tool is called a Krohn tool. You can search for these, but I can't point you at the specific wire-to-wire connector you are thinking of.

Telephone splice (Tel Splice), or more commonly - jelly beans.

The tool is shown here -

it is simply a pair of pliers with a 5mm gap between the jaws when closed. A normal pair of pliers can be used with a bit of care not to use too much pressure.

They are actually called B connectors.

And they are blue, and about 22 by 7 by 3 mm :)

Functionally these are the same as the more common jelly crimp

or as mentioned before. Both are IDC connectors and form a good electrical connection and waterproof the joint at the same time.
