I have two cables each with 13 wires coming together and I need to connect them with a terminal block. I am assuming that this exist but I am having trouble finding anything that does what I want. I have been looking on Digikey and Allied.

I'm afraid I don't have an answer, but I suspect if anyone's going to be able to help, you'll want to give them some indication of the size and type of wire, and application. (Data? Power? Wire gauge? Multi-strand or solid?)
I would have thought you'd be on the right track with "terminal block". Tried the word "distribution" in your search? "Junction"?

Check delcity.net, too.
I'm assuming you need this to be disconnectable? In other words, a bunch of butt connectors to splice the cables is not an option.
I haven't found anything with 13 wires, but you can get these in 2,3,4,6,8 and 12. Maybe get a 6 and an 8-pin one and leave a wire out. Waterproof and all that good stuff. http://www.delcity.net/store/Plugs/p_797540.h_797548.a_1.t_1
Or go yank something out of an existing car, preferably one where you can pull and replace terminals so you can do that instead of splicing.

16 AWG.
Basically it is just a way to extend the cable. So the wires match up between the two and it can't be something that requires soldering them or splicing them together. It has to be so that they can't easily be taken apart.

Yes it needs to disconnectable.
It is not for a one off thing so something out of a car is not an option. It is for a piece of production hardware but our electric engineer is so backed up I got stuck with this task and I know nothing about electrical stuff.

Amphenol plug?

I'm asking around the office about where we get OE connectors, although I'm not sure we've swum all the way upstream in the supplier river. See if you can find anything on Deutsch DT connectors.

I don't think Deutsch connectors will work because this connection is inside a box and the wires need to be able to be disconnected from the connection inside the box while at coal mines.

I'm not sure I follow. The connection is at a box, or in a box. For the latter, it seems the box is only a problem if there's a size constraint. If it has to plug into a box, the DRC series might work.

Terminal strips are pretty fool proof if the wires are numbered or color coded . Last amphenol military type I saw required soldering?

In a box. The wire has to pass thru a gland which will not allow a Duestch connector to pass thru.

How often is this connection disassembled? Is speed of connection an issue? How many amps ?

It shouldn't be disassembled often. Speed of connection isn't an issue but it needs to be able to done with handtools. 5 Amps.

Correct. Which is why the connection is in an XP box. They wouldn't be disassembled in hazardous parts of the mines.

Lotta liability laying on the table here, I'd give it back to somebody that makes enough money to make that kind of decision. eXplosion Proof is beyond my paygrade. You might start by looking at how similar situations have been handled in the past?

The connection is currently handled by a PC board with two terminal strips and a fuse on the power wire. We are having problem of the fuse holder breaking due to a combination of vibrations and clumsy hands when the fuse has to replaced. Since it is in a certified box the only thing called out in our certification drawing inside the box is the fuse and terminal boxes. Depending on the change that I end up finding, the drawing may have to go thru certification again.

That just sounds like an order of assembly issue to me. Run the wire through the gland, then crimp the connector on the end. If the connector has to be able to fit through the gland, I think you're SOL. You're trying to find a connector that's the same overall OD as the cable, and I just don't see how that's going to happen unless you have massive insulation on those wires.

I would say change the fuse holder to a more robust unit, but if this is called out that may require an major recertification and some other changes such as a switch on the enclosure access that kills power when opened. But then again I am just a piano player in a whorehouse, not an engineer

In reply to TRoglodyte:
I think that is going to be solution. The mines in South Africa claim they are breaking the part due to vibrations but looking at the part it is pretty clear to us that they are breaking off the fuse holder while changing the fuse.
I hate dealing with South Africa...
