Plug Connector Locking Structure for Readable Connection Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plug connectors rely on mechanical or visual checks for ensuring correct assembly, which are prone to human error and do not provide a reliable, quick method to verify a secure connection.
Innovation Solution
A plug connector design featuring a housing, locking element, and verification element, where the verification element is only readable when a correct connection is established, allowing for automated verification through machine-readable codes or chips, ensuring a secure and reliable connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical or visual checking methods are used to verify correct connection, then the assembly process can be monitored, but human error occurs and reliability is reduced
Solution Approach 1:
The patent uses a verification element with different visual appearances (machine-readable codes, colored markings) that are only visible or readable when the locking element is in the fastening position. This color/visibility change provides reliable verification without complex active sensing systems.
Solution Approach 2:
The locking element itself serves as the verification mechanism by covering or exposing the verification element based on its position. The system verifies its own state through the positional relationship between the locking element and verification element, eliminating the need for separate verification devices.
2Productivity
If a verification element is always visible, then connection status can be quickly identified, but the verification element can be manipulated before or during assembly
Solution Approach 1:
The verification element is prepared in advance on the housing, but its visibility is controlled by the locking element's position. The system ensures that verification only occurs after the locking element has been moved to the fastening position, preventing premature or fraudulent verification.
Solution Approach 2:
The locking element acts as an intermediary that controls the visibility of the verification element. It mediates between the verification requirement and the security requirement by exposing the verification element only when properly positioned in the fastening state.
3Reliability
If the locking element covers the verification element in the open position, then manipulation is prevented, but the verification element is not readable until fastening
Solution Approach 1:
The visibility state of the verification element dynamically changes with the locking element's position. In the open position, the verification element is covered for security; in the fastening position, it is exposed for verification. This dynamic state transition provides both security and timely verification.

AI summary
A plug connector includes a housing, a locking element and a verification element. The housing has a receiving chamber, a connection piece and a duct through which fluid can flow. The locking element is movable between an open position and a fastening position, a plug can be inserted in the receiving chamber in the open position of the locking element, and a plug inserted in the receiving chamber can be fastened within the receiving chamber via the locking element in the fastening position of the locking element. In an open position of the locking element, the verification element is at least partially covered by the locking element, and in a fastening position of the locking element, the verification element can be read.
