Electrical Plug Connector Pair With Pivoting Locking Hook And Sliding Bolt
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connector pairs often require additional effort to prevent unintentional release and can be difficult to uncouple, with some designs vulnerable to accidental detachment.
Innovation Solution
An electrical connector pair featuring a locking element with a pivotable locking hook and a longitudinally displaceable locking bolt, which secures the connection by engaging with a hook receptacle, and can be unlocked via a manually actuated area, ensuring secure locking and easy release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking element with a pivotable locking hook is used to prevent unintentional release, then the reliability of the connection is improved, but the ease of operation deteriorates due to additional locking mechanisms
Solution Approach 1:
The locking mechanism is segmented into two independent functions: a locking hook for preventing unintentional release and a locking bolt for secure locking. The locking bolt can be inserted or removed from the bolt receptacle to independently control the pivoting of the locking element, while the locking hook independently prevents separation of connector parts.
Solution Approach 2:
The locking bolt acts as an intermediary element that blocks the pivoting movement of the locking element when inserted into the bolt receptacle. This intermediary mechanism provides an additional layer of security without interfering with the primary locking hook function.
2Reliability
If a locking bolt is added to block pivoting movement, then the reliability of locking is improved, but the device complexity increases
Solution Approach 1:
The locking bolt and locking element are integrated into a unified structure where the locking bolt is arranged in a guide provided in the locking element. This merging reduces the number of separate components and simplifies the overall device while maintaining the blocking function.
Solution Approach 2:
The locking element serves multiple functions: it provides the locking hook for preventing unintentional release, contains the guide for the locking bolt, and acts as the structure that blocks pivoting when the bolt is inserted. This multi-functionality reduces the need for separate dedicated components.

AI summary
The invention relates to an electrical plug connector pair having a first plug connector part (1) and a second plug connector part (2) which can be connected to one another by means of a plug connection. According to the invention, provision is made for the first plug connector part (1) to have a locking element (3) with a locking hook (4) which, in a locking state, can be brought into engagement with a hook receptacle (5) which is provided in the second plug connector part (2), so that the locking hook (4) prevents the two plug connector parts (1, 2) from separating from one another, the locking element (3) is mounted in the first plug connector part (1) such that it can pivot about a pivot axis (6), so that the locking hook (4) can be released from the hook receptacle (5) by means of the locking element (3) being pivoted, a locking bolt (9) is arranged in a guide (8) which is provided in the locking element (3), so that the locking bolt (9) can be inserted into a bolt receptacle (10) of this kind on account of a longitudinal displacement, said bolt receptacle being arranged in a region of the first plug connector part (1) which is different from the locking element (3), so that a pivoting movement of the locking element (3) is blocked when the locking bolt (9) is inserted into the bolt receptacle (10). An electrical plug connector pair which can be locked in a simple and reliable manner is provided in this way.
