USB-C Locking Connectors
I constantly break my fp4’s USB-C port, and my brother’s very new fp5’s is not faring significantly better. Consequently, I propose a damn simple, industry-standard, and incredibly effective solution.
Although most USB Type-C cables do not provide any ability to remain in place except the mandated friction afforded by the connector, https://www.usb.org/sites/default/files/documents/usb_type-c_locking_connector_specification_rev_1_0_20160309_0.pdf#[{“num”%3A20%2C"gen"%3A0}%2C{“name”%3A"XYZ"}%2C87%2C708%2C0] defines two locking methods. However, usage of it necessitates that the cable and device vendor both implement one of the two standards (or both, but that’s not applicable here) and both implement the same standard(s). The types are:
Single vertical
Cables can be retrofitted to utilize this using OWC ClingOn USB Type-C and Thunderbolt 3 Connector or https://www.bhphotovideo.com/c/product/1399733-REG/sonnet_tb3_lok2l_thunderlok_3l_long_thunderbolt.html?sts=pi, but they are crude. Luckily, as https://www.amazon.co.uk/StarTech-com-Screw-Locking-Cable-10Gbps/dp/B09JCS5YVH demonstrates, first-party cables providing this functionality exist.
However, this locking method is fundamentally incompatible with almost all mobile devices, because it would necessitate some serious thickness. Consequently, see undermentioned.
Double horizontal
This is the version which I see potential for. You might consider the catch to be lack of vendor adoption, but https://www.amazon.co.uk/StarTech-com-Screw-Locking-Cable-10Gbps/dp/B09JCR5JQJ exists too.
Please add the small screw threads on the bottom of the fp6 and your subsequent cases in order to allow me to finally use the locking ability of the cables I own. I hope that your desire to have me purchase replacement ports won’t overcome your evident desire to find methods of reducing part failure rates for the sake of our planet.
