Removable Plug-In Contact Housing With Releasable Locking Hooks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plug-in connections with angularly designed pin or socket housings are permanently fixed to intermediate housings, making it impossible to remove them without destruction.
Innovation Solution
A non-destructively detachable design featuring a cylindrical pin or socket housing with elastic locking hooks and a locking ring, along with an unlocking tool with wedge-shaped bevels, allows for easy exchange and replacement by releasing the locking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the pin or socket housing is firmly connected to the intermediate housing using latching arms, then the fixation strength is improved, but the housing cannot be removed without destruction
Solution Approach 1:
The locking mechanism is segmented into separate components: the pin or socket housing, the locking ring, and the latching arms. This segmentation allows the housing to be firmly locked during operation while enabling non-destructive removal when needed, resolving the contradiction between strong fixation and ease of removal.
Solution Approach 2:
The locking mechanism transitions from a static permanent connection to a dynamic reversible connection. The latching arms can engage with the locking ring to provide strong fixation, or disengage to allow removal, making the connection strength adaptable to operational needs.
2Reliability
If the pin or socket housing is permanently fixed, then the reliability of connection is improved, but the adaptability for different housing types is reduced
Solution Approach 1:
The locking mechanism with the locking ring and latching arms serves multiple functions: providing reliable connection during operation, enabling easy removal, and allowing interchangeability of different housing types. This universal design resolves the contradiction between reliability and adaptability.
Solution Approach 2:
The connection parameters can be changed from locked to unlocked state by actuating the locking mechanism. This allows the same physical connection structure to provide both reliable fixed connection and adaptable interchangeability as needed.
3Ease of operation
If the engagement is made non-destructively detachable, then the ease of replacement is improved, but the fixation strength may be reduced
Solution Approach 1:
By segmenting the locking mechanism into separate engageable components rather than a monolithic permanent connection, the design achieves both easy replacement and strong fixation. The segmented locking ring and latching arms provide robust connection when engaged while allowing simple disengagement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy removal and replacement of pin or socket housings without damage, facilitating the use of different types of housings and improving component flexibility.
Implementation Method 1
The pin or socket housing has a locking ring and the installation area of the plug housing has at least one locking hook, which is arranged to be elastically flexible
Implementation Method 2
The unlocking tool has at least one wedge-shaped bevel at its end that can be inserted into the connector housing, which can contact the extension lug(s) after insertion of the unlocking tool into the connector housing and release or lift the locking hook(s) from the locking ring
