Connector Slide Lock Sealing Structure Against Unauthorized Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector locking mechanisms allow unauthorized detachment by moving a locking member, making it difficult to prohibit access to electronic control unit substrates.
Innovation Solution
A connector removal-restricting structure with a sealing member that slides into a locked state, contacting and engaging with a locking member to restrict movement, and includes a rib that breaks upon unauthorized access, preventing detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking member is provided to maintain the connected state of the connector, then the connector can be securely locked in place, but the connector can still be detached by moving the locking member to the unlocked position
Solution Approach 1:
The sealing member is attached to the connector body in advance before the locking member can be moved to the unlocked position. This preliminary action of sealing restricts the movement of the locking member, preventing unauthorized detachment while maintaining the ability to lock securely. The sealing member is positioned to contact the locking member and restrict its movement between locked and unlocked positions.
2Adaptability or versatility
If the locking member is made movable to allow unlocking, then the connector can be detached when needed, but unauthorized access to the electronic control unit substrate cannot be prohibited
Solution Approach 1:
The sealing member is attached locally to the connector body at a specific position where it can contact and restrict the movement of the locking member. This localized sealing action creates a barrier that prevents unauthorized movement of the locking member, thereby prohibiting unauthorized access to the electronic control unit substrate while preserving the normal locking/unlocking functionality when authorized.

AI summary
A harness-side connector 2 includes: a connector body 11 connected to a unit-side connector of a hydraulic unit 1; and a slide lock 12 supported by the connector body 11 to be slidable in the upper-lower direction. A sealing clip 3 is attached to the hydraulic unit 1 and the like in the locked state by moving upward while being restricted form movement in a direction intersecting the upper-lower direction. A first claw 29 of the sealing clip 3 is engaged with reinforcing ribs 8 of the hydraulic unit 1, so that the downward movement of the sealing clip 3 with respect to the hydraulic unit 1 and the like is restricted. The contact plate 15 of the sealing clip 3 contacts the slide lock 12 from below, so that the downward movement of the slide lock 12 with respect to the connector body 11 is restricted.
