Connector Resilient Lock Protrusion Assembly Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors face issues with improper assembly due to dimensional tolerances, leading to incomplete connections where the resilient locking portion protrudes, causing assembly errors and relative displacement issues between housings.
Innovation Solution
A connector design featuring a resilient lock with a protrusion on its outer periphery that corrects the tubular member's position during assembly by interfering with the receptacle, ensuring proper alignment and preventing backlash, while the resilient lock and protrusion are sandwiched between the housing main body and receptacle to regulate relative displacements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a clearance is secured between the front holder and fitting tube portion to accommodate dimensional tolerances, then the connecting operation can proceed smoothly, but improper assembly occurs where the resilient locking portion protrudes without the front holder reaching the proper mount position
Solution Approach 1:
The protrusion on the resilient lock performs preliminary action by interfering with the receptacle before the resilient lock can be fully locked to the receiving portion. This preliminary interference prevents the tubular member from being accommodated in an incompletely connected state, ensuring that the proper mounting position is achieved before final locking occurs.
2Ease of manufacture
If the resilient locking portion is made resiliently deflectable to facilitate mounting, then the assembly process becomes easier, but the tubular member may be assembled in an improper state with the resilient locking portion protruding
Solution Approach 1:
The protrusion acts as an intermediary element between the resilient lock and the receptacle. During the assembly process, the protrusion interferes with the receptacle to prevent improper accommodation, while the resilient nature of the lock allows it to deflect during mounting and then return to its locked position only when properly assembled.
3Strength
If the resilient lock returns to the inner peripheral side to lock to the receiving portion, then the tubular member is securely mounted, but relative displacement between housings can occur due to backlash
Solution Approach 1:
The protrusion performs preliminary anti-action by interfering with the receptacle to prevent the tubular member from being accommodated in an incompletely connected state. This preliminary prevention ensures that when the resilient lock returns to its locked position, the connection is already in the proper state, eliminating the possibility of backlash and relative displacement between housings.
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
The solution effectively prevents improper assembly and relative displacement between the first and second housings, ensuring reliable connection and simplifying the connector's shape by integrating the protrusion's position correction and backlash prevention functions.
Implementation Method 1
a resilient lock which interferes with the outer periphery of the housing main body in the process of assembling the tubular member with the housing main body and deflects resiliently out
Implementation Method 2
A protrusion is formed on an outer periphery of the resilient lock and is configured to correct the tubular member into a properly assembled state by interfering with the receptacle

AI summary
A first housing (10) of a connector includes a housing main body (11) with a receiving portion (17) and a tubular member (20) surrounding the housing main body (11). A peripheral wall (22) of the tubular member (20) has a resilient lock (24) configured to deflect resiliently out when assembling the tubular member (20) and the housing main body (11) and to return resiliently to lock with the receiving portion (17) when the tubular member (20) is assembled properly with the housing main body (11). A protrusion (31) is formed on the outer periphery of the resilient locking portion (24) and is configured to interfere with a receptacle (61) while fitting the tubular member (20) into the receptacle (61) so that an improperly assembled tubular member (20) is corrected into a properly assembled state.
