Re: [IC-7000] Source for IC7000 ribbon cables.

Having repaired many 7K's over the past 11 years I can confirm that ALL of the flex connectors DO INDEED HAVE a release clamp that must be pulled up to release the pressure on the contacts before removing the cable.  Failure to do so will usually pull the plastic stiffener/alignment piece off of the back of the cable.

The clamp must be in the UP position before reinserting the cable, then pushed down flush with the connector top, insuring that the cable is fully seated in the process.

The ZIF clamp is a very thin brown plastic "flange" that is on both edges and the back side.  I use a smal dental pick to pull up each side about (less than a 1/16") to release it.

I can tell you for a fact most Icom flex connectors are not a form of ZIF connectors. They do not have clips, levers, gates or any external tension devices. If you are unfamiliar with them, removal is risky, re-insertion is an order of magnitude riskier! In IC-7000's, there are two high density flex cables between the main unit and the PA unit. I see them damaged all the time from erroneous alignment when inserting them into the main unit connectors. Worse, if they come out of the PA board connectors, you have to remove the PA unit to get them back in.

As a general rule, most "flex" style cables have gates on the companion connectors that must be raised to release the cable. Failure to do that will result in torn-up cables. The "gate" is usually a small plastic "cap", that is usually a contrasting color, on one side of the cable entry point that can be lifted at each end to free the cable. On re-insertion, you want to push the "gate" back down to capture the cable and move the contacts into position.

Removing the PA board or analog board requires removing the two ribbon cables at the rear.
After sitting there for ten years they won't like to be pulled out.
Easy to destroy them. Parts of the solder coated contact strips come off, and then later when re-inserting them, they fail completely.

Before re-inserting the cables put some contact oil on the ends.
I used non-oxidizing weapon oil sometimes, when no contact cleaner was available.

Their prices are reasonable, and the service is perfect.
The number is the original ICOM part number.
You need two pieces of course.

I have found another source on Aliexpress, but not yet received my orders.
