Fitting Connector Dustproof Wall Shaving Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fitting connectors generate metallic shavings during assembly and disassembly, which can enter between the fitting parts and adhere to waterproof members, compromising the seal and durability.
Innovation Solution
A fitting connector design featuring a dustproof wall and an elastically deformable coupling part that prevents shavings from reaching the fitting parts, using a screw structure with a male and female screw configuration to generate axial force and maintain a seal, while the dustproof wall is partially cylindrical and positioned between the connector fixation wall and the screw part.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If metallic screw parts are used for connector assembly and disassembly, then connector fitting and fixation can be achieved, but metallic shavings are generated that can enter between fitting parts and adhere to waterproof members
Solution Approach 1:
A dustproof wall is introduced as an intermediary structure between the screw part and the fitting part. This wall acts as a barrier that intercepts metallic shavings generated during screw operations, preventing them from reaching the fitting parts and waterproof members. The dustproof wall is integrated into the connector housing and positioned to cover the path from the screw area to the fitting area.
2Reliability
If a waterproof member is provided between fitting parts to seal the gap, then liquid tightness is improved, but metallic shavings can adhere to the waterproof member during connector operations
Solution Approach 1:
The dustproof wall serves as a protective barrier that shields the waterproof member from metallic shavings. By positioning the dustproof wall between the screw generation area and the fitting part area, shavings are prevented from contacting the waterproof member, thereby maintaining its sealing function without degradation.
Solution Approach 2:
The harmful factor (metallic shavings) is extracted or isolated from the sealing area by the dustproof wall. The wall creates a separated zone where shavings are contained away from the waterproof member, allowing the sealing function to operate independently without contamination.
3Adaptability or versatility
If screw parts are fastened or loosened repeatedly, then connector assembly and disassembly is enabled, but metallic shavings are continuously generated and potentially dragged between housing and waterproof member
Solution Approach 1:
The dustproof wall provides continuous protection during repeated assembly and disassembly operations. As the screw parts are fastened or loosened multiple times, the dustproof wall consistently intercepts generated shavings, preventing them from being dragged into the sealing area between the housing and waterproof member.
Solution Approach 2:
The dustproof wall is pre-positioned in the connector structure before any assembly operations occur. This preliminary protective structure is already in place to intercept shavings from the first operation onwards, preventing contamination before it can occur during any subsequent assembly or disassembly cycles.

Function Achieved in This Case
Prevents shavings from entering between the fitting parts, maintaining the seal and preventing degradation of the waterproof member, thus enhancing the connector's liquid tightness and durability.
Implementation Method 1
a screw member including a first screw part, disposed opposite to an outer peripheral surface of the first fitting part at an interval and held rotatably about a screw axis relative to the first case, the screw axis being aligned with a direction in which the connectors are inserted and removed relative to the second connector
Implementation Method 2
the second case includes a coupling part that is elastically deformable in the tube axial direction and through which the dustproof wall is coupled with the second fitting part side
