Crimping Heat Shrink Terminals the Right Way

 

 37A13011 Heat Shrink Crimp Tool

Crimper for heat shrink terminals

Have you ever ruined a heat shrink terminal when you were trying to crimp it on the wire? Chances are, you need a better tool to make sure you don't puncture the heat shrink protection around the terminal. We have just the solution - a ratchet style crimper specifically for 22-8 ga. heat shrink terminals.

Crimping 101

Tuesday, July 30, 2013 3:22:18 PM EST

Crimping Tips

 

A bad crimp will cause premature failure of your electrical connection. Below are a few tips to ensure a proper crimp.

 

 

Insulated terminals need two crimps, a crimp of the nylon or plastic sleeve onto the wire jacket and a crimp of the metal insert onto the wire. High quality crimping tools will perform both crimps with one squeeze of the handle, 37A13001 is an example. To ensure the insulation is not broken, the crimps are general arcs that flatten the circular body into more of an oval shape, like this:

 

Insulated Terminal Crimp, Before and After

 

Heat shrink terminals need even more care from a crimp than insulated terminals because if the heat shrink is punctured, the terminal is compromised. Our specialized heat shrink terminal crimper, 37A13011, has a broad crimping surface to apply pressure across a large space to ensure the heat shrink is not cut.

 

Bare terminals require only one crimp of the barrel onto the wire. 37A13002 is an example. The crimping zone has more of a soft B shape to it, that creates a crimp that looks like this:

 

Bare Terminal Crimp, Before and After

 

Metri-Pack, Weather Pack, Deutsch terminals require specialized crimpers. While a basic crimping tool might appear to get the job done, what you can't see, may affect you. Ensure you find a tool that can crimp your specific terminal. A few suggestions below:

Nylon Terminals

Tuesday, July 30, 2013 3:09:07 PM EST

What's so special about nylon terminals?

    Ring Terminals

There's more to nylon terminals than you might think!

 

Nylon terminals offer a higher quality connection than their plastic or bare insulated cousins. So what's the difference? 

    Nylon Ring Terminal

Nylon terminals offer vibration resistance thatplastic and bare terminals do not. While nylon,plastic,and bare terminals require an electrical crimp to secure the terminal to the wire strands, only nylonterminals require a second crimp. The mechanical crimp on nylon terminals crimps the extra tin-plated brass sleeve to the wire insulation. The mechanical crimp along with the extra sleeve protect against extreme vibration and weather that commonly cause circuit failure due to wire breakage. 

 

Spending the extra cents per piece to get nyloninsulated terminals may result in a connection that lasts for years rather than months.

Cable Ties

Tuesday, July 30, 2013 3:02:10 PM EST

Add Some Zip to Your Cable Tie Knowledge


                       UV Black Cable Tie                                                Green Cable Tie                                        Screw Mount Cable Tie

 

Cable ties are used everywhere: from holding wires together to fastening components quickly and easily. Like duct tape, cable ties are an essential tool for life's challenges. So what's there to know?

 

Stand Up to the Sun

The sun's UV rays will cause the common cable tie and even some black cable ties to become brittle and fail. UV black cable ties will last 5-15 years under the sun where the common natural/clear cable tie will only last months. Note that not all black cable ties are UV resistant, but all of ours are!

 

Make Security and Identification Easy with Color-Coded Cable Ties

A lock prevents access while a clipped cable tie makes it apparent that someone needed access to a locker, cabinet, or bundle of wire. Using a red or green cable tie will not allow someone to simply replace the clipped cable tie with a new one. Color-coded cable ties can also be used to blend in so they are more aesthetically pleasing.

 

Specialty Ties - Screw Mount and ID Tags

Want to hold a bundle of wire in the middle of a wall? Use a screw mount cable tie. Need to write a serial number, date, or other identification information on an item? ID tag cable ties allow you to write on them.

We have every cable tie variety known to man. Want some advise on the best cable for your application? Give me a call or shoot me an email!

Fuses and Circuit Breakers

Tuesday, July 30, 2013 2:52:23 PM EST

Fuses and Circuit Breakers: Shorting the Confusion 

 

Fuses and circuit breakers are used in everyday components such as in your car, construction equipment, and other electronics. Fuses and circuit breakers satisfy a simple question: When bad things happen with electricity, would you rather ruin your $100+ electronic item or a $0.40 fuse? Fuses and circuit breakers are used as safety devices in electrical circuits to help eliminate damage from overheating due to overflow of current. Let's see if we can take the complexity out of fuses and circuit breakers.


 Common automotive fuses:

  

ATO and ATC

 ATO/ATC

 

Mini

 Mini

 

Low Profile Mini 

Low-Profile Mini

Maxi

 Maxi

 

-Older technology

 

-Large footprint

 

-Best seller across time

 

-Most common fuse installed today

 

-Smaller footprint

 

 

 

-Newest - the future

 

-Smaller height than Mini

 

-Not compatible with Mini footprints

-Higher amperage protection

 

-Largest footprint

 

Circuit breakers are made to replace automotive fuses. Rather than needing to be replaced after the first spike, circuit breakers are able to be reset. Circuit breakers commonly have three reset styles detailed below.

                                                         

      

 

Automatic Reset (Type I)

Power-Off Reset (Type II)

Manual Reset (Type III)

When overflow occurs, the breaker will blow and reset itself automatically.

When overflow occurs, the power needs to be turned off and back on for the breaker to reset.

When overflow occurs, the circuit breaker needs to be manually reset by pressing a button or a switch.

 

 

Inline fuse holders are an easy and inexpensive way to protect an add-on electrical item or to provide additional protection to a device in a system. Installation is simple, just splice this into your wire. LED versions allow you to identify blown fuses in hard to reach places.

                                                        

  

Surface mount fuse panels give you a convenient way to protect multiple circuits away from the fuse panel. They often have a common feed-in and protect at higher amps. Some can even act as a kill switch to ensure your battery does not drain when devices are not in use.

Keeping Moisture Out of Your Electrical Connections

Tuesday, July 30, 2013 9:36:47 AM EST

Seal out water before it corrodes your electrical connection.

 
Water, especially salt water, causes corrosion and premature failure of electrical connections when it is allowed to come into contact with your copper wire. You'd be more surprised to hear that water can enter where your wire is stripped. The water can then "wick" its way all throughout the system through the straw that is the insulation or jacket of the wire. This leads to corrosion of not just the portion of the wire exposed to the water, but the entire length of the wire as well as the system the other end of the wire connects to.

stripped wire and terminal
       
With minimal effort, you can prevent the moisture from entering your system - no expertise necessary.
 
The easiest way to seal out moisture is by using heat shrink terminals. After crimping the terminal onto the wire, when heat is applied to the body of the terminal, it shrinks onto the exposed wire and it's jacket to seal out anything from entering the system.

Another option is to use heat shrink tubing to create your own heat shrink terminal. Similar to a heat shrink terminal, the terminal is crimped onto the wire, and then heat shrink tubing is fitted over the top of the exposed wire. Apply heat and now you have a water tight seal.

A bit of upfront effort now can save quite a bit of future maintenance.
