Possibilities Provided by an SAE 2 Pin Connection

by on Oct.07, 2011, under Hello World!, SAE 2 Pin

If you’re a Biker, check out the possibilities provided by the SAE 2 Pin connection on your Fused Quick Connect “pigtail” (if you have a Deltran Battery Tender, and installed the included assembly on your motorcycle’s battery):

As the saying goes – a picture is worth a thousand words…  Made up this display to get the point across –  there are quite a few assemblies that will couple up to your Fused Quick Connect “pigtail”.  These assemblies address applications ranging from extending reach to facilitating things like adaptation of 12 Volt “cigarette lighter plug” type cell phone chargers, and COAX heated clothing (example: heated gloves) connectors.  In addition, there are butt ended assemblies allowing do-it-yourselfers to install their own accessory circuits for charging such hand held electronics as GPS units and iPods.

So, it can be visualized that the SAE 2 Pin connector on your Deltran Battery Tender “Fused Quick Connect” pigtail provides access to your motorcycle’s battery and charging system 12 volt power.  This, in addition to providing the means to conveniently and effectively maintain and thereby extend the life of your bike’s battery.

The SAE 2 Pin connector is often alternatively called an SAE 2 Prong, SAE 2 Pole, SAE 2 Conductor connector, as well as a “flat” or “trailer” connector.  Generally speaking, it is intended for 12 Volt DC applications.  Assemblies with this connector can often be found in your local automotive store – usually in the form of a 12″ extension.  Widely imported, the quality and durability fits lighter applications.

Although some of the displayed assemblies are imported from abroad, those made for Bohemian Biker LLC (and to our specifications) are manufactured here in the USA !!! The higher quality of these SAE 2 Pin connectors manufactured here in the United States is obvious – they are sturdier, and have greater strain relief.

Additional Blog Posts pertinent to the above products can be found via headings at the top of webpage.  Note – It is very important for anyone attempting to use these assemblies to have a clear understanding of electrical concepts such as “polarity”.  We highly recommend educating oneself along this line.

More about Bohemian Biker LLC

by on Oct.04, 2011, under Hello World!

Bohemian Biker LLC and its blog type website www.bohemianbiker.com are the result of a man’s passion for interaction, and especially interaction with those oriented toward “doing-it-themselves”.  Ray Bowers had always dreamed of “being in business for himself”, and stumbled upon his niche once realizing most battery maintenance equipment and portable solar charging equipment employ the same connector type – an SAE 2 Pin connector.

Upon discovering this, Ray’s first endeavor was the development of a manufactured 12V power port x SAE 2 Pin assembly to access a motorcycle’s 12V battery and charging system power for charging cell phones, etc.  What he envisioned was an assembly of the specific length that would reach  from a Battery Tender “Quick Connect” pigtail to a motorcycle’s adjacent saddlebag.  Thanks to the help of an especially patient sales representative, Ray was able to negotiate the manufacture of  the assembly he believed would be popular.  Sure enough, the assembly did indeed prove popular, and that initial design has remained popular for several years now.

With that taste of success, Ray began contracting the manufacture of additional assemblies he believed would be useful.  Some were designed to be used in a specific application.  For example, a heated  glove COAX “female” x SAE 2 Pin assembly – avoiding the installation of another battery pigtail.  Others were designed to facilitate “do-it-yourself” circuit building.  For example, a circuit taking its feed off a Battery Tender pigtail to support 12V power port charging of a handlebar mounted GPS unit.

Customers seeking higher capacity assemblies, and Ray’s own desire for SAE 2 Pin assemblies with heavier gauge leads for ideas he had, encouraged him to begin contacting the manufacture of SAE 2 Pin connectors with 16, 12 and 10 AWG leads.  One such idea Ray had been sitting on was 10 AWG assemblies to facilitate the “jumping” of a motorcycle without the necessity for seat removal.

Truth is, Ray is pretty focused on utility.  He has no bells or whistles on his blacked-out ape-hanger’d ’01 Road King – no handlebar mounted gizmos, no frills.  But, he does have an extra 10 AWG pigtail hanging adjacent to his Battery Tender pigtail.  An engineer by education and work experience, product development is another exciting aspect of “minding his own business”.  Ray spent 25+ years in heavy industry – nuclear power, oil and chemical, as well as manufacturing.  He has also spent a few years as a teacher-naturalist and shooting instructor.

What Ray finds especially enjoyable is talking a customer through a “do-it-yourself” project.  He loves to hear the level of confidence increase as a not so knowledgeable soul grasps something like the reason behind the polarity of a circuit component.

As a Baby Boomer, it’s taken significant self-study for this 56 year old to keep up with such concepts as online “search priority”.  On his Bohemian Biker website, Ray includes a quote from Ralph Waldo Emerson – “Do not go where the path may lead; go instead where there is no path and leave a trail.”

BTW – SAE 2 Pin assemblies that Ray has developed are manufacturer right here in the USA !!!

12 Volt Accessory Cable Kit Component Polarity and Amp Ratings

by on Jun.20, 2009, under Application

 

12V Accessory Cable Kit

Swapped emails with the supplier of our 12 Volt Accessory Cable Kits concerning the amp ratings of the individual component cable assemblies and decided to post the results.

Considering this kit is included with the Global Solar SUNLINQ line of Portable Solar Chargers (6.5, 12, and 25 Watt), the components are meant for relatively light amperage applications…mostly…charging handheld electronics. As I’ve discussed in other posts, there are other applications for which the components of this kit are suited.  For example, coupling a 12 volt cell phone charger to a Battery Tender Quick Connect using the power port cable assembly and in some cases the 8′ extension cable.

These two components fit nicely into this application because the SAE 2 Pin on the end of the Battery Tender Quick Connect basically replicates the SAE 2 Pin on the output of one of Global’s Portable Solar Chargers.  Specifically, the protected “female” socket side of the SAE 2 Pin connector on the end of the Quick Connect is “hot” (+) positive.  Therefore, the “exposed” male pin of the SAE 2 Pin connector on the power port assembly leads to the centerpost of the power port socket…which must be “hot” (+) positive.

Now let’s look at an application in which things don’t work out similarly well.  Someone might have the idea they’d like to couple the power plug assembly to the output of their Battery Tender…such that they may insert the power port plug into the cigarette lighter socket of a vehicle of which they’d like to maintain the battery.  NO GO!  Won’t work!  Think about it…  If the protected “female” socket side of the SAE 2 Conductor Connector on the  “Battery Tender Quick Connect installed on your motorcycle’s battery is “hot” (+) positive…the “exposed” male pin on the output of your Battery Tender must be “hot” (+) positive.

Now back to out power port plug – remembering we were saying above…the SAE 2 Pin end of these components is meant to be plugged into an SAE 2 Conductor connector with a “hot” (+) positive “protected” female socket.  So, we have a “polarity” issue here to which we must pay close, careful attention.  Stop and think thing through…thoroughly…before you start coupling connectors together. 

The power port plug has an integral 2 amp fuse, so that component’s amp rating is pretty evident.  This is ample capacity for many applications – charging most handheld electronics, etc.  When you get into attempting to power something like a portable air compressor, it’s a different story.  Even a tiny air compressor may draw 7 or 8 amps, or more.  So, this power port plug would not have the rating to be used in an application such as this.  In fact, even the heavier duty power port plugs we handle (stand-alone…without SAE 2 Pin)…are fused at 5 amps…which would still be less than an application such as this might require.  Obviously, power port plugs must be available for this application…because there are miniature compressors employing them…stretched to the limit as they may be.  

What about that 12 volt power port!  It’s rated at 7 amps max.   In most cases borderline unacceptable for the air compressor application we discussed above, but providing plenty of capacity for handheld electronics.  But, think about it this way…that Battery Tender Quick Connect installed on your motorcycle battery probably has a 7.5 amp fuse.  So, the 5 piece accessory kit’s power port cable assembly fits nicely into that parameter.

Heated gloves might be OK plugged into one of these power ports…but as always…check the manufacturer’s specifications.  Obviously, stacking up multple pieces of heated clothing is going to put you over the maximum amperage rating.

Speaking of heated clothing…often employing COAX connectors…we’re prompted to talk about the “male” COAX “barrel” connector x SAE 2 Pin adaptor that comes as part of the 5 piece accessory kit.  Once again…7 amps.  So, maybe OK for gloves…but not much more.  Now this brings me to an application that I discuss in another post – using this adaptor to facilitate the maintenance of your battery via the COAX “female” heated clothing pigtail you might have installed on your motorcycle’s battery.  I cannot condone this practice, but figuring that won’t stop some…here’s the problem.  It’s the same polarity problem.  Once again, the polarity is opposite what you need to couple the SAE 2 Pin end to the output of your Battery Tender.   

But…alas…I came up with an easy fix…a “rig” of sorts.  Again, I cannot condone this practice…and for that reason…I sell the components as a “do-it-yourself” kit.  Basically, I provide you with the components to assemble what I call a “Hot Socket” Adaptor.  That is, there is continuity between the “protected” female socket at each end.  Therefore, there is a “female” socket to accept the “hot” (+) positive pin of the SAE 2 Pin connector on the output of your Battery Tender…and the respective Adaptor conduct leads to a “hot” (+) positive “protected” female socket at the other end…to accept the “exposed” male pin of the SAE 2 Pin on the COAX cable.  Now, the male COAX end of the COAX Assembly has the correct polarity…and can be coupled to the “female” COAX end of the Heated Clothing pigtail installed on your motorcycle’s battery.  This does the trick for those that wish to avoid having more than (1) pigtail dangling from their battery.

About those Battery Terminal Clamps (component of the 5 piece kit)…  Same situation…  The “exposed” male pin of the SAE 2 Pin of this assembly leads to the red handled (+) poitive alligator clamp.  Therefore, opposite of what it should be…to be coupled to your Battery Tender output SAE 2 Pin.  This assembly carries a 15 amp rating, but remember you’d still be limited by the lower amperage rating of (for example) the 8 foot extension.

This being a post covering a lot of components, topics, and issues…I will no doubt be adding to it in the future…

SAE 2 Pin “Hot Socket” Adaptor

by on Apr.21, 2009, under SAE 2 Pin

hot-socket-pic-002

An application that a customer brought to our attention for a COAX male “barrel” x SAE 2 Pin cable assembly (component of 5 piece accessory kit) prompted us to develop a do-it-yourself kit to facilitate the assembly of this adaptor. 

The DIY “Hot Socket” Kit includes: (2) SAE 2-pin connectors (as described below) plus (2) sections of heat shrinkable tubing (HST) to aid in making up a neat assembly.

     (2)   SAE 2-pin connectors with 6″ (+/- 1/4″) pigtail leads. 

              18 AWG red wire with PVC insulation leading to protected (+) socket.

              18 AWG white wire with PVC insulation leading to exposed (-) pin.

Connecting “red wire to red wire”…”white wire to white wire”…will result in an assembly with a “hot (+) positive socket” at each end for applications in which this is desired.  This essentially reverses polarity…in that…if you have an SAE 2 Pin with the “exposed” male pin as the “hot” (+) positive (for example, at the output end of a Deltran Battery Tender)…and you wanted to accomplish having a “hot” (+) positive “protected” female socket…this “Hot Socket” Adaptor provides that result.

This assembly could be used in applications in which there is a desire to make a transition from an SAE 2-pin connector with an “unprotected” hot (+) positive “male” pin to an SAE 2-pin connector with a “protected” hot (+) positive “female” socket at the resulting end.  Potential applications for one of these assemblies need to be carefully thought out with respect to polarity !!!

Here’s an application in which we are aware of purchasers applying this adaptor:  If it was one’s desire to connect a Deltran Battery Tender to a battery via an already installed heated clothing type COAX connector pigtail…using the “barrel connector” included in our 5-piece Accessory Cable Kit…this adaptor would provide the necessary adaptation.  Noting…and cautioning…that the normal 7.5 amp fuse protection of the Deltran type Quick Connect would be circumvented…and you would be banking on the heated clothing pigtail’s inline fuseholder/fuse (a higher value/inadequate protection…unless the fuse was swapped out to provide the normal 7.5 amp protection).  We cannot recommend or condone this practice, but we are aware that some purchasers are using this adaptor in this way.

There are other applications for this handy adaptor that come to mind.  For example, our Power Port Plug x SAE 2 Pin cable assembly (another component of the 5 piece accessory cable kit).  We have a customer that wants to put this plug assembly on the output of his Battery Tender, and plug it into the lighter socket to maintain the battery of a car he stores.  Once again, the configuration difference between the SAE 2 Pin on the end of the Battery Tender output and the power port plug assembly present a similar application for the “Hot Socket” adaptor.

Heated Clothing COAX x SAE 2 Pin Adaptor Cable

by on Apr.05, 2009, under COAX

Heated Clothing COAX x SAE 2 Pin Adaptor Cable

Heated Clothing COAX x SAE 2 Pin Adaptor Cable

For those Bikers that want to minimize the number of Quick Connects attached to their battery – albeit vigilant about maintaining their battery – we offer this Heated Clothing x SAE 2 Pin Adaptor Cable.
Recognize the limiting factor when tapping into your battery/charging system via the Battery Tender Quick Connect is the amperage value of the integral fuse – often 7.5 amp.
We contract a manufacturer here in the USA to produce these assemblies.  The same manufacturer that produces our 12V Power Port assembly.  Therefore, this  Heated Clothing x SAE 2 Pin Adaptor Cable has the same high quality SAE 2 Pin connector – sturdy and easy to grasp.  The COAX connector is of similarly high quality.
Assembled with approximately 9″ of Black SPT-1 Cord / 18 AWG conductors in between connectors.  Overall length: 13″ (approximately)
COAX (female) end

COAX (female) end

 This is similar to what the 2.5 mm COAX “female” end of our Heated Clothing x SAE 2 Pin Adaptor Cable looks like – up close.  Picture provided to add further clarification of what we’re calling a “female” COAX connector.  The molded body of this connector varies slightly from ours.

12 Volt Accessory Cable 5-pc Kit w/ SAE 2 Pin Connect

by on Apr.05, 2009, under Accessories

12V Accessory Cable Kit

12V Accessory Cable Kit

This handy accessory kit is comprised of 5 cable assemblies with SAE 2 Pin connect.  The kit includes: 12V Power Port, 12V Power Plug, Battery Terminal Clamps, 2.5mm “male” COAX adaptor, and an 8 foot extension cable.
These cable assemblies can be indispensable.  Coupled with the necessary 12 volt charger, they can facilitate the charging of a cell phone and other electronics.  They can also facilitate the trickle charging of a 12V battery.
The SAE 2 Pin end of these assemblies is meant to be connected to a “power side” SAE 2 Pin connector leading from a power source, i.e., one with a hot (+) positive socket.  In other words, the exposed “male” pin of the SAE 2 Pin connector on the end of these assemblies is meant to be hot (+) positive.
The power port cable assembly, for example, has the conductor leading from the exposed “male” pin of the SAE 2 Pin leading to the (+) positive center post within the power port.   The power port plug assembly, similarly has the conductor leading from the exposed “male” pin of the SAE 2 Pin leads to the (+) positive center post  at the end of the power port plug.
Special attention is required with respect to the battery terminal clamp assembly.  The fact that it is wired similarly…(making it useful for trickle charging, etc., when connected as described above) …makes it unfit for use connected to the output of a Battery Tender.  Here’s why – the SAE 2 Pin connector at the end of a Deltran Battery Tender output has a (+) positive exposed male pin to match up to the SAE 2 Pin of a properly installed Deltran fused Quick Connect…which will have a hot (+) postive female socket.
These are light duty 12 volt cable assemblies, as indicated by the 2 amp fuse integral to the power port plug x SAE 2 Pin assembly.
