content: I want to make up some quick connect/disconnect pigtails, so I can quickly swap end connection types.I want a solid connection. 2 pin mate n lock are too flimsy.I was considering using these:https://www.jpmsupply.com/product-p/95327.htmwhich I think are TE 172129-1I've used them before but I recall them being maybe too solid aa they required quite a bit of effort to connect/disconnect.Anything else?I want a connector, not a jack.

content: Take a look at the R/C ones instead of the Automotive ones. Generally Gold plated and designed for multiple cycles.https://hobbyking.com/en_us/batteries-chargers/battery-accessories/battery-adaptors.htmlMy preference is the original Deans connectors but the T connectors here are close in performance for bench usehttps://hobbyking.com/en_us/mini-black-t-connector-pack-5-pairs.html?queryID=f63a450ce730aeaf0e5e41e1682117c5&objectID=27737&indexName=hbk_live_magento_en_us_productsThe alternate now is the XT60 or 90 with the 60 making more sense for bench currents.https://hobbyking.com/en_us/genuine-xt60-nylon-connectors-male-female-5-pairs.html?queryID=c2921b046fb9c5f6a7f6ef88960ae1bc&objectID=83975&indexName=hbk_live_magento_en_us_products

content: Happy snap of 'some' of my charge/test/bench adapters.Some of them are based on the Mini Deans connectors (circa 10-12A) but generally the larger ones make more sense.

The upside is they are not male and female so no issues with that side.

content: I'm not sure why you think the previously linked unit would be any better mechanically than a mate and lock. the big problem is that these connectors would not be safe in the application you are suggesting. You really need to consider them as low voltage devices no matter what the spec says, it is pretty easy to come into contact with live parts.One of the first thing that came to mind for me is the industrial M8 connector. For example:https://www.digikey.com/en/products/detail/harting/21023592301/8034752.The problem here is that most of them have threaded metallic locking collars which introduces a safety problem. Ideally you will use a connector that is all plastic on the outside. We use similar at work and if it wasn't for the metal they would be ideal.So what I would do is to start looking at the various all plastic circular connectors available. One example woulld be an Amphenol X-Lock :https://www.digikey.com/en/products/detail/amphenol-ltw/BB-02BFMA-QL8MPP/7898286.This particular one is a bit bulky but the idea is to look for something similar. Hirose has a slightly less bulky unithttps://www.digikey.com/en/products/detail/hirose-electric-co-ltd/JR13WP-3P-31/9170950.An even smaller Switchcraft unit :https://www.digikey.com/en/products/detail/switchcraft-inc/EN3C2MX/1289237.In any event there are many similar connectors to choose from. Then you have connectors like Power Poles. Here is some information:https://www.digikey.com/en/products/detail/anderson-power-products-inc/1399G9/10650306.These can be safer than the cheap plastic connectors but I still wouldn't be excited to see them used in a high voltage domain, there is however a "finger safe" variant. These connectors are very popular in ham shacks but still are probably more than you need for signal sources.Then you have XLR connectors:https://www.digikey.com/en/products/detail/amphenol-sine-systems-corp/AC3FCP/10443106.Just don't use them if you have audio gear that is near by. Designed for audio so I have no idea of the voltage or current ratings.Quote from: dorkshoei on February 15, 2021, 03:50:43 am

content: QuoteAll your links are broken edit them and drop for following fullstop seems to work.This is a bench situation not an industrial facility. Generally all the connectors suggested above are used regularly in the sub 50V range. Anderson Power Poles suck balls btw too we dumped them 20+ years ago their contact resistance is terrible!The connectors linked cope with 100's of cycles auto mate and lock types are not meant for that duty.KISS for the win here.
