Repairable Connector Bracket for Prying and Twisting Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors are prone to damage when subjected to external forces such as prying or twisting, which can compromise their functionality and integrity.
Innovation Solution
A repairable connector design featuring a bracket with a barrel portion that surrounds the plug connector to maintain orientation and a support portion fixed to the circuit board, dispersing external forces and preventing damage, combined with a modular structure for easy replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the plug connector is directly mated with the receptacle connector without additional protective structures, then the device complexity is reduced, but the connector becomes vulnerable to damage from external forces such as prying or twisting
Solution Approach 1:
The connector system is divided into separate functional components: a receptacle connector mounted on a module substrate, a bracket that provides mechanical protection and mounting, and a plug connector that interfaces externally. This segmentation allows each component to be optimized independently - the bracket handles mechanical stress while the receptacle connector handles electrical connection, resolving the contradiction between simplicity and durability
Solution Approach 2:
The bracket acts as an intermediary element between the plug connector and the module substrate. It provides mechanical support, orientation maintenance, and force distribution, mediating the interaction between external forces and the delicate electrical connector components, thereby protecting against damage without adding excessive complexity
2Ease of manufacture
If the receptacle connector is directly mounted on the circuit board, then the manufacturing process is simplified, but the connector cannot be easily replaced when damaged
Solution Approach 1:
The connector system is segmented into a replaceable module (receptacle connector mounted on module substrate within bracket) and a permanent mounting structure (bracket fixed to circuit board). This allows the connector module to be easily replaced when damaged while maintaining simple overall manufacturing, as the bracket provides standardized mounting interfaces
Solution Approach 2:
The mounting system transitions from a static direct-soldered connection to a dynamic modular assembly. The bracket provides fixed mounting to the circuit board while allowing the connector module to be detached and replaced, creating a system that adapts between permanent installation and replaceable components based on maintenance needs

AI summary
A repairable connector includes a connector module and a bracket mounted on the connector module. The connector module includes a receptacle connector configured to be mated with a plug connector from outside an enclosure, a module substrate on which the receptacle connector is mounted, and a board-to-board connector that is mounted on the module substrate and electrically connected to the receptacle connector via the module substrate. The bracket includes a barrel portion and a support portion. The support portion is fixed to an internal circuit board.
