Abstract:
This disclosure proposes a new connector to help solve a field issue with aging SDL cables with a broken or missing plastic latches.
Background:
We encounter some severe field issues that FPGA IC burnt out in the field. The short circuit condition happens when the cable to connector fit is loose due to a broken latch on the cable end. The customer is not willing to change their cable although old or has a broken latch or swap the cash drawer cable to prevent it happening. We, TGCS, are usually the one they blamed first place and are required to repair if the system in under warranty or a service contract.
Description:
Our idea is to design a new SDL cash drawer receptacle connector to prevent this issue permanently. With current SDL receptacle connector mechanical design, it heavily replies on the plastic latch on the cable plug side connector. It also doesn't have a clear definition of the tolerance to each other. The plastic latch is proven to be easily broken and will definitely cause us a problem.
Please refer to the attached picture that shows how we design the SDL receptacle connector that it still be compatible to any predecessor SDL design without any problem. It provides a press fit to eliminate the gap due to the tolerance..
