I was salvaging the connectors from a fraying micro usb cable (that came with an LG G4 phone) and found that the connectors have a unique construction (see image below, Source: https://www.alibaba.com/product-detail/Micro-USB-B-Crimping-Type-Connector_60483560958.html). Instead of the wires being soldered to pads or pins on the connectors, the wires are inserted into a plastic housing (white piece in the image below) with thin slots on one side. The housing is then pushed down onto the toothed pins, which pass through the thin slots, displace the insulation on the wires, and contact the copper within.
This design requires no tools besides wirecutters, obviously does not require any finicky soldering, and is robust and disassemble-able. So I was surprised that these are pretty obscure parts. I found a couple of ebay and alibaba listings, but none on aliexpress or DigiKey. Do these have a standard name? Are they available from Hirose or other brand names?
