Why you should ONLY use heat shrink terminals.. Part 2

In a previous blog, I touched on how big of a problem corrosion is.  The next reason why you should only use sealed, heat shrink connectors is to help protect against wire pull-out.  Wire pull-out is often found in areas of high vibration or where long periods of strain or pulling on your wires may occur.  Connectors that are exposed to weathering and UV rays can also be susceptible to wire pull-out over time.

Electrical Failure can also occur when constant strain and/or vibration causes a wire within your electrical system to come loose.

Electrical Failure can also occur when constant strain and/or vibration causes a wire within your electrical system to come loose.

By using a heat shrink connector, you add extra tensile strength to your crimp and/or solder termination that a standard, unsealed vinyl or nylon connector does not have.

Troubleshooting electrical failure is EXPENSIVE.  Help prevent costly downtime to your electrical systems by using sealed, heat shrink terminals from NSPA today.

Solder vs Crimp connectors… which is a better solution?

Crimp versus Solder.  This age-old question goes back to our first caveman electricians.  Okay, maybe not that for back, but it is a question we hear ALL the time.  There really isn’t a definitive, one answer that fits everyone either.  We like to think of it as a user preference.  Here are some things to think about that will hopefully help you make your decision.

  1. Are you comfortable making a solder connection?  Often times, a “cold” solder joint can lead to electrical failure to do “pull-out”.  Installers must wait for the wire’s strands to heat up to promote good solder flow.  Typically, the bigger the wire, the longer the install time.  A good solder joint will allow the solder to flow in between your wire’s strands for maximum conductivity and strength.
  2. Do you have the right tool to crimp with?  Often times installers will try to crimp a terminal with the wrong tool.  This can damage the connector and can leave your connection at risk for failure.  Over-crimping a terminal can actually break the copper strands of your wires causing unintended resistance and less than optimal current flow.

Whether you choose to crimp or solder… or both… always use a weatherproof, heat shrink connector.  Do it Once, Do it Right!
