Hi all,
Can anyone suggest a secure plug or terminal block that will fit on a BTS7960 eight pin header? Dupont connectors are coming loose. Thanks for your time.
What does the other end of the cable plug into?
You could replace the dirt cheap male pin header with a latching variant such as the ones shown below and use an IDC connector with ribbon cable in it.
An Arduino terminal block shield
I use THESE or something similar quite a bit.
Get a female header to mate to the 8 pin header. Solder wires to the female.
There are several other solutions as well.
Doesn't he need female connectors for male pins?
As I said:
That may not be easy to desolder pins.
Heat up a hobby knife and use the hot blade to melt through the plastic surround, isolating each pin.
Remove one pin at a time.
And the next objection will be "will it fit"? Not a problem in my wheelhouse. 
I used a 2x4 housing and crimped on female pins to wiring. There’s enough friction to hold it in place without a lock. If you don’t want to spend $$$ on a crimper, you can find sets of JST rectangular 0.1” spacing housings and wires with precrimped pins on Amazon.
- Tie wrap the cable to the PCB.
- Silicone glue will work and is still removable.
Thank you. Those look like they just might do the trick
Let us know if they work. There are several variants. I did have to buy a special crimper for them, also available at amazon.
I would first try applying a thin layer of epoxy carefully around the eight female in-situ DuPont connectors.
Epoxy is fairly permanent. I use hot glue a lot in those situations, and when I had a boo boo, I was still able to re-do the connections by just re-heating. For normal use, equally strong and long-lasting.
Of course single jumpers aren't secure.
Assuming it's a 2-row, 4-pin arrangement on 0.1" pitch, obtain or cut, two deep female headers, each 4-way, and glue them together to get a 2 x 4 block.
In normal usage, will not come apart.
Molex KK types come in all sorts of arrangements and are locking.
Downside is needs inserts and a crimping tool, but worth the effort.
Also JST, same principle.
Advantage of the last two is polarisation.
Yes to hot glue when it’s likely to be a temporary fix. I’m assuming not in this case.
One other advantage of thin epoxy I’ve found in similar cases is the option to surround the group with a labeled tape.
