Cable Connector Metal Shell Opening Prevents Solder Shorting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The fully sealed metal shell in existing cable connector assemblies often causes shorting with the inner soldered portion, which is a common issue affecting their performance.
Innovation Solution
The metal shell is designed with an opening adjacent to the soldered portion of the cable to prevent shorting with the metal shell, ensuring that the soldered portions of the power and grounding wires are exposed on the outer side of the metal shell, thereby avoiding contact with the metal shell.

1Object-affected harmful factors
If the metal shell is fully sealed to improve anti-EMI performance, then electromagnetic shielding is enhanced, but the soldered portion may short with the metal shell
Solution Approach 1:
The patent extracts the soldered portion from the enclosed space by providing an opening that exposes the soldered portion to the external environment, separating it from the metal shell interior and eliminating the shorting risk while maintaining EMI shielding for other components
Solution Approach 2:
The metal shell is segmented into enclosed regions and an opening region, creating distinct functional zones where the opening serves as an escape path for the soldered portion while the rest of the shell maintains its shielding function

AI summary
A cable connector assembly (100) adapted for mating with a mating connector includes a connector (200) connected with a cable (300). The connector includes a mating member (1), a metal shell (4) disposed at an outer side of the mating member and the cable, and an outer shell (5) enclosing the metal shell. The metal shell defines an opening (43) adjacent to a soldered portion of the cable soldered with the connector to prevent the soldered portion from shorting with the metal shell.
