<sup>*Note: I am torn between posting this here, SE DIY or SE IoT. Since this is related to powering on my smart devices and the electrical connection I need to use, I finally settled down on SE EE. Please let me know if this is out of scope and I will move it somewhere else*</sup>

I have a Nuki Smart Lock and I want to do exactly what the manual says not to do:

I would like the USB cable to cross the frame of the door by using a "connector" - a device that would have a set of bare metal endings on both side that can touch and provide a closed circuit, and be disconnected when the door is open. The connector on the Nuki is a USB-C.

My main problem is that I do not know how such device is called in English (now that I think of it I could also post at *SE English Learners* :)).

Is there a standard way for a USB-C cable to be split that way?
