Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors with shielding nets fail to securely retain signal transmission modules during vibration and movement, leading to reduced grounding shielding effectiveness.
Innovation Solution
A baffle is integrated into the connector housing to prevent disengagement of signal transmission modules, with a shielding net positioned between the baffle and module channels, utilizing shielding elastic sheets or protrusions for secure contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a C-shaped grounding shielding member is used to provide electromagnetic shielding, then the shielding function is satisfied and assembly is convenient, but the signal transmission module may deviate during vibration and movement, reducing grounding shielding effectiveness
Solution Approach 1:
The grounding shielding member is divided into multiple independent grounding contacts instead of a single C-shaped structure. Each grounding contact can independently contact the shielding net, providing multiple contact points that maintain grounding effectiveness even when the module deviates during vibration and movement.
Solution Approach 2:
The grounding contacts are designed to be movable or elastic, allowing them to adapt to the position changes of the signal transmission module during vibration and movement. This dynamic design ensures continuous contact and maintains grounding shielding effectiveness under varying conditions.
2Reliability
If a shielding net is provided to ensure signal quality, then electromagnetic shielding is achieved, but the signal transmission module may detach from the connector during vibration and movement
Solution Approach 1:
The shielding net is integrated with the housing structure through multiple contact points, creating a unified stable structure. The shielding net is not just a separate component but is firmly attached to the housing, preventing module detachment while maintaining shielding effectiveness.
Solution Approach 2:
The shielding net is pre-installed and firmly attached to the housing before the signal transmission module is inserted. This preliminary action ensures that the shielding net is already in position and can effectively prevent module detachment during subsequent vibration and movement.
3Adaptability or versatility
If multiple individual chambers with chamber walls are provided on housing, then universality is improved for different application scenarios, but the grounding shielding effect is reduced due to semi-surrounding design
Solution Approach 1:
The housing design with multiple individual chambers maintains universality for different application scenarios. Each chamber can accommodate different signal transmission modules, and the standardized chamber structure allows for flexible configuration while the improved grounding contacts ensure effective shielding for each module.
Solution Approach 2:
The grounding contacts are specifically designed at critical locations where the shielding net contacts the housing. This local quality improvement ensures effective grounding shielding at key points without compromising the overall modular and universal chamber design.

AI summary
The present utility model relates to a shielding net and a connector using the shielding net. The connector comprises a housing. The housing is provided with a plurality of module channels therein. A signal transmission module is movably mounted in each of the module channels. The signal transmission module comprises an insulator and a signal contact member. The housing is further provided with a shielding net. The shielding net has a plurality of mesh holes. The signal transmission module is provided with a shielding ring sleeve segment. A shielding contact conductively bonded to the shielding ring sleeve segment of a corresponding signal transmission module is respectively provided at each mesh hole of the shielding net. The shielding contact protrudes towards the center of the corresponding mesh hole. A plurality of the shielding contacts corresponding to each mesh hole are circumferentially disposed along the corresponding mesh hole, so as to form a fully surrounding arrangement. When the connector is applied in a vibration and deviation scenario, there is a corresponding shielding elastic sheet conductively bonded to a shielding ring sleeve on each of the signal transmission modules regardless of the direction in which the signal transmission modules deviate, thereby effectively ensuring a grounding shielding effect of the shielding net for each signal transmission module.
