Printer Port Connectors "DB" and "db"

I'm not aware of any "db25" series connectors - I would expect both upper and lower case designations to refer to the same style of connectors, but the upper case designation is correct according to the original manufacturer.

The D-subminature connector family is available in both insertable-pin and solder cup formats (as well as IDC and solder-to-board styles.)

If you are looking for pins to insert into the wiring side of a pinless housing, you _must_ get the appropriate pins, made by the manufacturer of the housing. (AMP pins don't work in Cannon housings, and vice versa, although complete AMP connectors mate with complete Cannon connectors.)

Well, I won some connectors on eBay:

And only one side fits my printer cable. The other side has the correct spacing but is loose meaning the holes are larger.

Also, I have no idea who the manufacturer is of these.(There is a little insignia that looks something like an "S/A").

Thanks.

Those appear to me to be empty connector bodies intended to accept insertable contacts. Is there any metal inside the pin cavities? doesn't look like it from the photos.

I don't recognize the "S/A" insignia - any other part number? Are they male or female housings?

(My guess is that you've wasted $21.00...)

eBay:

There is another sign stamped on it, but it doesn't look like a letter.

I can't be sure, but I see no pins inside either. Can "insertable contacts" be gotten from anywhere?

Thanks.

eBay:

Based on the limited (non-existent, really) information on that eBay site, I wouldn't buy the things. I recognise them as insertable contact housings (because I use lots of them at work), but can't tell whether they are male or female, nor can I tell what make they are.

The side that fits your printer cable is the actual connector side - where a mating connector fits. The loose side is the wiring side of the housing. This is where you insert contacts with wires attached. If you mounted the connector on a box containing your circuit, the loose side would be inside the box, and would have the wires going to your circuit.

Yes - but as I mentioned previously, you _must_ use contacts from the manufacturer of the connector housing.

The Cannon logo looks something like an old-fashioned artillery cannon

- a circle representing the wheel, a line to the right at the top of the wheel to represent the barrel, and a line to the left at the bottom of the wheel.

The insertable contacts are available from any company that sells that make of connector - Digikey and Newark should have them (but, I must repeat, you need the right make). They, and the connector bodies, will usually be listed under "D subminature connectors". To use the insertable contacts, you should have the correct crimping tool, and a contact removal tool is very useful, as well.

If you can't positively identify these connectors, I suggest you attempt to return them to the seller, and buy the connectors you need from a reputable vendor.

Yes, they are without pins.

looks like part of a configurable DB25F to modular socket patch connectoer, eg.

(you have the part on the right.)

individual inserts are also avalable, leaded.

and uncrimped,

These have been re-branded "dynAmix" I don't know who the original supplier was.

bye.

on second thought, I have handled them and they look very similar the drawing in the datasheet here

possibly the E-Bay vendor can supply the pin inserts, or tell you where to order them.

Well, that is one possible application.

At work we use this style of connector as the standard D-sub connector for making cables and on custom equipment. It is much easier, quicker, and neater to crimp contacts on the wires, then insert them in the connector, than to have to solder all the wires individually to solder-cup connectors.
