The Stovebolt Site Forums The Shop Area The Electrical Bay Dual crimp terminals - source

I still haven't figured out what terminology to use which may be why I can't find a good complete source. I am looking for connectors that crimp both the bare wire and a second crimp above on the insulation.
I have seen sources that have maybe one type or another, but not good selection of all primary connector types (ring, spades, bullets, male/female blade, etc) with the dual crimp.
I have been to the Stovebolt Electrical Wiring links, but I'm not seeing what I am looking for.
Is there a technical term I need to search on for these types of connectors and any suggestions on a vendor(s)?

See if you can find what you are looking for here:

The ones you are looking for are pretty much the standard for any electrical supply or industrial supply house. They commonly insulated, since most of the uninsulated ones are supplied on reels for automatic crimping machines. About the only place I see the wire crimp only terminals are at a hardware store or FLAPS.

Thanks for the quick responses! I been to the Grainger and McMaster-Carr and other sites where they have multitudes of connectors, but I don't know the right keyword to filter it down just to these types of connectors with the double/dual crimp. I paged through Graingers and if they were there, I missed them.
Here is an example of a disconnect BM-8 terminal from Ron Francis's web site. It shows the two crimps on the connector.

Now to get an assortment that has all the different connector types with this double/dual type of crimp that is what I want.
On AmericanAutoWire, they have a video showing crimping these connectors, and they do have pin connectors (for pin lug brake light swithces) and headlamp disconnects, but not loops or spade lugs. American AutoWire Crimper Video
There has to be a term for that extra crimp around the wire insulation, and I just don't know what it is.

The Packard 56 type terminal you show is usually meant for use in a connector type application. Now known as Delphi/Packard. You see in your pic a bent up tab, that is to catch a lip inside connector to retain. If you want a ring tongue terminal that goes over a stud, use a standard insulated one and add heat shrink if you desire. If you want the uninsulated Packard 56 type ring tongue with a crimp for the wire and a crimp for the insulation, I found them at Texas Industrial Electrical Co. Other vendors are Waytekwire and Terminal Supply Co. Did not see any ring tongue Packards at those two. Keep in mind that when you say dual crimp, there are terminals that are made for two crimps on the wire. Used in the Space and in the Nuclear industries.(not what you want) Go to the above websites and search Packard or Packard 56. This is the name of the original 50's (1956) connector system used in Automotive. (Weatherpack is common now). The 56 is a .25 blade width and there are Packard 58 and 59 blade sizes (larger). I purchased the connectors and contacts from Terminal Supply Co. when I did my own wiring harness. $25 minimum order. Excellent people and products. They do require shrink sleeving. Most uninsulated ring tongue terminals are barrel type. These terminals are a bit pricey. .98 each. Now that you know the name you can search web for other suppliers. I believe you will find all the other type of terminals you mentioned at the Co.'s I gave. BTW: these are called terminals or contacts not connectors. A connector is the shell they fit into. (plugs and receptacles). There is a crimp on "disconnect" terminal. If a seller calls terminals and contacts: connectors, they are technically incorrect. I worked at a connector company, thus I am picky. I think you would say a terminal is for use without a connector and a contact is used inside a connector. The subject of the post is crimped or soldered products on the end of a wire. There are other uses for the words like battery "terminal" and switch "contact". TMI.

I've purchased connectors from both of these places and been satisfied.

Dig through mouser.com

Well, I would not have thought this would be so hard, especially with all the good suggestions and sources I was given. The terms I have found for the feature I want is "vibration support" or "insulation grip" (which provides vibration support). I would think that I would want this feature just as much on my "ring tongue" terminal for my screw type oil and temperature sender as I do on my headlights. I guess the industry doesn't agree (or at least not the way I wanted). It appears fairly easy to get a barrel connector either insulated or non with the insulation grip. I recently purchased a pair of Accel 170036 crimpers and was very impressed with the plug wire crimps. It includes a set of dies for "primary connectors" that is (for lack of better terms) a "W" crimp. Having seen the disconnect terminals with the vibration support insulation grip, and the tool having multiple guage slots, again I just figured I could get hook tongue, ring tongue, fork tongue, etc terminals. I have been to all the recommended sites above, plus the Panduit catalog and other search hits, but haven't found any yet.
Yes, I'm one of those that when I get it in my mind how I want it done, it will continually bug me knowing I couldn't do it that way.
btw, yes, many suppliers state that their insulation band or head shrink provides the insulation grip or vibration support, and to some degree it does and may be all I am going to get.

yes, it's all you'll get .... the terminals with shrink insulation do the job well, my local supplier has excellent ones, and they also have the 'funnel' type I think you're looking for that could use a double crimp, but they're nylon insulated, inferior to the ShrinkTerm style .... no need for NASA spec stuff on an old truck

The added shrink sleeve over the skirt will give support (as in fulcrum support) and some pull-out strength and vibration resistance. Plenty good enough for your truck. If you have applications for wiring onto a stud or for a screw, use only ring tongue, never spade. You can get shrink sleeved terminals as Bill suggests. Here is some more info to keep you awake. There is a special, original style, right angle, insulated terminal used on the gauges. It slides onto the stud. They came with my American Autowire Kit. Don't know who sells them. Proper tie wrapping, harness design and clamp spots will eliminate most vibration and provide strain relief. Use many small zip ties along the branches no matter how big or small the bundle is. It makes a real nice looking, round, more manageable harness. Try different routing to assure no chaffing or pinching and provide serviceability. As goofy as it sounds, I do like liquid tape for high moisture environments/locations. If you are worried, just test your crimps, pull on the terminal or on the wire and see what you think. There will be no problems.

Now the humor starts. Instead of spending 20 cents on a connector, I want to spend 98 cents (just cause I wanna). Others spend $10K on a paint job when $350 from Maaco will keep it from rusting (probably long after they own it). I know just a plain crimp terminal will work (most likely long after I own it), but that isn't what I wanted. I like the look.

Don't shake your head as you go for another bottle of wax and buffer pad :-).

No problem with that reasoning because it's your truck and your money. We have given you the vendors and nomenclature you requested and TMI. As Devo says. "Get straight. Go forward. Move ahead. Crimp it. Crimp it good". I get you like the look but 99.987 % of the terminals are never seen by human eyes after installation.

if you want "the look" of a real professional job, and one that will last with no problems, use soldered on connectors and heat shrink ... and do your cabling with waxed nylon cord using MilSpec techniques

...and those pages are from Wikileaks.

Ok, here is an update. AMP/Tyco Electronics (now TE Connectivity) makes these terminals. They are "open barrel with insulation support".
Manufacturer link
Jameco Electronics has some. Don't ask me why they only show up under "ring tongue WITHOUT insulation grip". Browse about halfway down the list.
--JAMECO--

they're shown as 'without insulation grip' because they have no insulator, the mfgr lists them as 'with insulation support' because they're the "dual crimp" style you think you want, the 2nd crimp grabs the insulation .... and they're all for small wire gauges, listed as 'NOT heavy duty', the common type of terminals used in electronics, not automotive

if you're going to have to use some heat shrink insulation anyway, and other style terminals for larger wire sizes and different types of terminal, why use those for limited locations? certainly there are more important criteria for electrical work than 'looking cool'

Bill

They make them in multiple thicknesses (according to the the TE Catalog), so yes, you would probably want the thicker ones.
I'll just have to order a sample and make sure they would be suitable for automotive use.
