I recently ran across "crimp sleeves" or some such at a web site, associated with a leaded electrical component.  Although it wasn't explicit, I gathered that this is simply a small metal tube which can be used to crimp a wire to the lead of the component.  This approach would be convenient in a couple of cases:  using resistors in lieu of fuses or circuit breakers for low-amperage circuit (for example, with LED lighting or indicators, one could put the current limiting resistor at the bus rather than the device, and no additional circuit protection would be necessary);  or diode functions could be implemented in the wiring harness.



I've found no other reference or source to anything like this.  Is my interpretation correct?  If so, where might one find "crimp sleeves", beyond that one site?  I assume this would be limited to lead-to-wire vs. lead-to-lead (as might be used in cascading components) - is this the case?  What components are suitable for this approach?  The sample was actually an axially-leaded thermostat, but I'd hope/expect it would work with leaded resistors and beefy-bodied plastic-encapsulated diodes.  And that leaded reed switches would be a really poor choice.



Thoughts?



Thx,

Jon

   There are a number of such products that I saw in common

   usage at Beech. Installing in-line components was not

   allowed but they WERE used to splice wires and COULD be

   used to install components.



   Here's my own favorite technique for 'homeless' components.

   The goal is (1) good electrical connection and (2) support

   of vibration prone solid wires including the solid-by-solder

   strands of the wires.

    Yup.

   You got that right!
