content: I am trying to locate the connector / connector housing and hardware to make a cable with an end that mates to the DB9 connector in the picture below. The connector itself is a standard DB9 male, but notice that instead of screws it has some sort of pin to which something latches. I thought it was the "Slide Lock" mechanism sold by Conec, but I ordered two Slide-lock equipped housings from DigiKey, but what I got will not latch onto that. I might just be missing a piece, or could be the entirely wrong thing.Can someone who is familiar with this please help me locate everything I need to build a cable that attaches to this?Thanks

content: That does look like it.I assume you do not have the matching power connector?

content: Yes, I agree that it looks like it. Maybe I should contact TE and ask them to send me a complete list of parts.I don't have the mating connector to compare with. This connector actually supplies power to the device (no idea why they are using a 9-pin connector designed for low amperage signals to a device that draws 48W). So what I have right now is just a DB9 connector that's just resting in there, and I've already knocked it out several times while working around the area where that connector is.

content: I sent a question to TE Connectivity via the form on their web site.Thanks everyone for the help. If someone has direct experience with this connector, I would appreciate if you can add detail or confirm if we're on the right track here.

content: Think the pins are rated to 1 amp5 ground 4 power 0.5 per pinWould guess that only mounting bolts are different.From what I have seen that style holds better then the slide lock that does both sides at onceC

content: Quote from: MarkF on August 07, 2015, 03:09:39 amI think so, Mark. That will be my fallback if I can't get this slide lock thing figured out.

content: My eyes could be deceiving me, but that looks quite a bit like the slide lock used for Ethernet AUI.http://www.aim-ele.co.jp/products/aui/images/aui-big.jpgRetention is not all that good, and it has the downside of requiring you to reach between the connector shell and the panel to operate.You can also see that the locking piece fits over a regular D-sub socket and is retained with screws.[But I should point out that not all D-sub pins are created equal and some carry higher current than others.]

content: Quote from: motocoder on August 07, 2015, 02:36:01 amYou can buy the lock as an accessory for DB9 connector:http://www.digikey.com/product-detail/en/160-009-002R031/160-09SLA-ND/1008073but I can not find matching shell. You can also just ignore the lock and use DB9 connector without locking.

content: Quote from: motocoder on August 07, 2015, 03:31:20 amWill do, It is strange considering that both boxes use several amps. I will also try to see if any of those are different when hooked into the main distribution box.

content: Quote from: Vgkid on August 07, 2015, 03:48:12 amI've been wanting to ohm out the connector to see if any of the other pins are connected, but I don't want to disconnect the thing right now as the OCXOs seem to finally be aging nicely.

content: I will check mine, the internal ocxo has rather crummy specs.(I narrowed it down to 2 possible choices VectronC4710, or MTI-250. I unhooked it as the gps stopped locking suddenly after mooving it(bad connector)Oh well I'm building a Shera gpsdo, and contemplating another gpsdo.Vectronhttp://www.vectron.com/products/ocxo/c4710.pdfMTIhttp://www.mti-milliren.com/pdfs/250.pdfhttp://www.mti-milliren.com/prodDetail/250/253_mech.html

content: I got a reply from TE Connectivity today. They sent me several assembly diagrams, but the most useful document is the assembly instruction sheet. I am attaching that here now and will follow up with part numbers once I have a confirmed working set-up.

content: Ok, these slide latches work:TE Connectivity Part Number: 5206942-1DigiKey Part Number: A33703-NDhttp://www.digikey.com/product-detail/en/0/A33703-NDEach kit comes with latches for both sides of a single connector. The housing ears must not be too thick for the screws to go through. I ended up using the TE Connectivity housings that don't have any ears. I'm not real happy with those, but everything did fit, and the connector can't fall off anymore.
