Spring clamp terminal blocks12/20/2023 ![]() Feed-Through/DIN Railįeed-through terminal blocks are used to connect two wires together for wire-to-wire connections. Barrier strips are commonly used where vibration is a concern. These terminal blocks have a screw down terminal where a ring or spade terminal is attached to the wire and then inserted onto the screw and tightened into the housing. PCB mount terminal blocks can be single, dual, or multi-level modules. The housing is then soldered to a PCB in common footprints. Often referred to as Eurostyle or wire-to-board terminal blocks, PCB mount terminal blocks work by inserting bare wires into the module where a clamp secures the wire in the housing. These are some of the most common: PCB Mount There are various types of terminal blocks that can be used in a design. They are ideal for designs requiring secure, well-organized, and semi-permanent wire connections that can be easily swapped out for inspection or repair in the field. Terminal blocks-also referred to as terminal connectors, connection terminals, or screw terminals-are used in a wide array of applications where electrical systems need to be safely connected.

Is it possible to put a connector on the enclosure for these replacements? Depending on how much your downtime cost you per hour it could be justified by the time saving alone of connecting one connector instead of multiple wires. I personally still wouldn't use a screw clamp for your application. Of course my first question would be why are you looking at fixing a connection problem that is caused by the removal and insertion of wires instead of fixing the problem that is causing you to have to remove and insert the wires, ie sensor failure.but you didn't ask that question. In a perfect world you could just train everyone to use them properly and the problem would be solved but old habits die hard and some guys just don't work well under pressure. The more urgent fixing the breakdown is, the harder they seem to pull which causes damage, especially the the lightweight guillotine style clamps like you see on instrumentation. Also when people are in a hurry they will pull on the wire, then release the clamp. ![]() ![]() You press the clamp lightly and the block opens, but they people think you need to put an extra 25lbs of force on it to open it up that extra 1/64" which crushes the spring in it to the point of damage. One big problem I still see with some of them is that there is nothing to stop you from pressing the clamp open too far. The early ones required special installation tools, maintenance personnel couldn't figure out how to remove the wires and would break them in the process, I've even seen them wire nuted around because the guy couldn't figure out how to work them, etc, but they have come a long ways. I even went out of my way to special order parts without spring clamps. I resisted the change to spring terminals for a long time. ![]()
