Steve,
The ability to shear the leads is dependent on the lead material. If
they are copper or bronze, no problem. If they are Kovar, problem.
In any case, it may be beyond the ability of commercial leadformers, but
you can check out Schleuniger, as they make those types of lead trimming
equipment.
They use an angled blade, so you are really only cutting a few leads at
a time.
I once developed my own shear for a similar connector but it had Kovar
leads, very hard metal to cut. I used a Bimba pneumatic cylinder press
turned horizontal, and mounted it on the bottom of a platform with a
steel bed above it. The connector was then placed into the holes drilled
into the steel bed, and when the footpedal was activated the Bimba press
pushed a diaganal tool steel cutter along the bottom of the bed, thus
trimming the leads. It worked extremely well, so much so that we built
several of them for similar radial lead trimming applications. It was
much cheaper than buying the commercial presses.

Subject: [TN] Connector Shear...
Morning All!
We have an assembly here that we're trying to reduce the labor on. It's
a rigid-flex board that has this high pin count AbleConn connector
installed. Take a look at:

and:

I'm looking for a shear that can trim all the pins to length in one
shot. You've probably seen them before, you know, a pneumatic foot pedel
operated little gizmo.
I've got a Simonds unit here and am not too happy with it. Besides, it
doesn't have the capability to shear pins in that large of an area.
Fancourt makes a unit called a D-2C/L lead cutter that has a 4" X 4"
working area and should handle this connector. I'm currently waiting on
a quote from them.
I'm just checking with you all to see if you know of anybody else that
might make a lead shear to do this connector. There's over 450 pins on
this little jewel and we're having to trim them one-by-one.
I know what you're thinking and before you ask, I already checked. We
can't get the connector with the pins already trimmed to the length we
need them...
Kind regards,
-Steve Gregory-
