Hello.quite a simple question,I am looking for a elegant way to power an object that embeds led strips.In order to move this object, I want the power cable to be unpluggable.Can I put a female 3.5mm phone jack plug on my object and solder a male plug to the end of the power cable?My strips specs are the following0,4A/m /12 volt white color.I will use 2.5 m of strip.If jacks can't do the job, is there other nice cheap plugs I can use?thanks
3.5mm phone connectors are OK for low voltage and low current. However I would recommend you use the stereo (3 pole) rather than the mono type. The mono type uses the socket body as one of the connection poles and this is unreliable since there is no "pressure" applied to this pole - it simply relies on touch contact. I can state this from experience of using such connectors for a similar project. If you use a stereo jack the outer two poles are connected by spring loaded contacts and therefore offer a much more reliable connection.
That all depends on :a) length of cableb) make-up of cable (number of strands of what cross section per core) or better still the resistance of the cable/metrec) current drawn by the load3.5mm are OK for low currents 10s rather than 100s of mA. You might be able to push an amp or so through them but you could end up with contact problems = heat = even more contact problems. Lots of gadget chargers use 3.5mm plugs as charge leads so they are capable of carrying current.Have you thought about using RCA phono plugs/sockets. These are much bulkier but they can carry a lot higher current than the 3.5mm jack.
Just make sure it is inflammable.
