What is the proper name of this 7 pin audio connector?

HF90M is a Q-Mac HF90M manpack military HF transceiver. Very compact and rigid (drop-shock-water-etc resistant), will fit even some large pocket, too.

I got it on local junkyard store for very cheap, complete with TA-99 tuner (which is plain roller inductor, controlled with stepper motor), but without mic. Spare mikes are available online, but for civilian HF90 model, which uses different connector (easily available one, you can find such one on modern digital soldering irons).

Regarding the manufacturer name, it only says amphenol, nothing more.

Hah, sometimes advanced online searching gives great result.

Leaflet describes connector as "Pattern 105 handset connector". Further googling reveals the following: "Aerco now holds in stock the AB05 military specification connectors from AB Electronics that are fully approved to the stringent requirements of Defence Standard 59-35 (Part 1) section 3, Pattern 105.

It appears this was made by an Australian company which was bought out by Barrett Communications of Australia. The website refers one to call the Barrett offices regarding this radio.

Amphenol - Well that is a start.

I didn't look for an Amphenol catalog, but there are some unique features to help pin it down once you have a legend from the catalog.

The contact pattern of one in the center and 6 around all the same size will be given a name and shown as a drawing.

Pin/Socket size will also be an identifying feature. Catalog should have details of how they are sized and named.

The keying is done with three tabs/slots of different size and location, again another unique feature shown as a drawing.

This last one is the hardest for me to identify. The latching does not look like a screw-on, but either push and 1/4 turn or just a push-on and pull-off. At the 12 o'clock position looks like a ball-bearing on the shell so I am thinking push-on/pull-off.

It is not going to be quick or easy, but I am thinking that with the 4 features outlined you should be able to find the connector. Measurements of the physical part will help if you find more than one. Usually the data sheets will have 2 view drawings of the connector in english/metric dimensions.

I did look at the Mouser site and they do have a good advanced filter, but it hinges on knowing what terms to select to narrow down the choices. That why I would focus on the Amphenol catalog if one can be found. Often times you have a long convoluted part number and you need to break it down to figure out what you have. In this case it is reverse engineering from the part to a part number.

Divide and Conquer

Good Luck!

While typing I see more information has come forward.

Ordered the chinese one. Should arrive here next week. Let's see.

Just wondering... Is there a way around this?

I mean, find a connector, both male and Female and buy them the same size as the holes in your chassis and just replace what's there with the new. 7 pins isn't too hard to change out.

This way, you won't have to waste money experimenting plus you can buy extra for anything else you need to plug in to what ever this goes into.

Unfortunately - no. Since this radio is sealed, front panel is constructed in the special way, a plastic has been poured in around the connector, after the complete soldering process. So, only one way of removing connector is to carefully drill it out, and then soldier a new one. I already ruined another front panel of such transceiver, when trying to determine, how front panel assembly was done.

Here's a close up picture of connector at radio.

Even if I unscrew these nuts, connector can't be removed, since it's back is filled with plastic goo, which is very hard to remove. Also, pins from connector go directly to PCB, which is also molded into surrounding plastics. So, I can't just simply pull back PCB, to release connector.

To me, it looks like the connector will not fit that socket. About the only thing that looks the same is the pin pattern. The radio jack looks like it is made for a bayonet style plug, the keyways are different, and maybe the physical size is wrong.

What about just contacting Barrett Comm? THey bought Qmac in '09, and have service/tech offices here in the states.
