Connector Assembly Locking Structure for Reliable Mating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector assemblies face challenges in maintaining the reliability of the positional relationship between connectors under external forces, which can lead to contact loosening or damage to components.
Innovation Solution
The proposed connector assembly incorporates interlocking locking structures, including elastic locking arms and locking protrusions, to securely mate the first and second connectors, preventing detachment in unintended directions and enhancing structural strength against tilting forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the first connector is inserted into the receiving slot of the second connector to achieve electrical conduction, then the electrical connection between conductive components is established, but the positional relationship between connectors may become unreliable under external forces
Solution Approach 1:
The connector assembly is divided into separate first and second connectors that can be mated together, with each connector having distinct structural features (first connector with first insulating body and conductive components, second connector with second insulating body and receiving slot). This segmentation allows for independent optimization of each connector while maintaining reliable mating through the locking structures.
Solution Approach 2:
The locking structures are designed to automatically engage when the first connector is inserted into the second connector. The locking protrusion on one connector fits into the locking slot of the other connector during the mating process, preventing detachment before any external forces are applied. This preliminary locking action ensures positional stability is established before operational stresses occur.
2Reliability
If locking structures are added to prevent detachment and improve mating reliability, then the structural strength and stability are enhanced, but the device complexity increases
Solution Approach 1:
The locking structures are integrated into the insulating bodies of the connectors rather than being separate components. The first insulating body includes a locking protrusion, and the second insulating body includes a locking slot, merging the locking function with the insulating structure. This integration reduces the number of separate parts while maintaining the reliability benefit of positive locking engagement.
Solution Approach 2:
The insulating bodies serve multiple functions: providing electrical insulation, structural support for conductive components, and incorporating locking features (protrusions and slots) for mechanical engagement. This multi-functionality reduces the need for separate dedicated locking components, thereby reducing overall device complexity while maintaining reliable mating.

AI summary
A connector assembly includes a first connector and a second connector. The first connector includes a first insulating body, a number of first conductive terminals, and an adapter circuit board. The adapter circuit board includes an input end and an output end. The input end includes an input portion electrically connected to the first conductive terminals. The output end includes an insertion portion protruding beyond the first insulating body. The second connector includes a second insulating body and a number of second conductive terminals. The first connector and the second connector further include locking structures to prevent the first connector from being separated from the second connector.
