Electrical Connector Cam Member Rotation Constraint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connector systems face challenges in ensuring secure and efficient mating and disconnection of connectors, often resulting in unreliable connections and potential damage to wires due to inadequate locking mechanisms and strain relief.
Innovation Solution
The proposed electrical connector system incorporates a housing with a slide and cam member, featuring a rack section with teeth and a connector position assurance (CPA) member, which engages with a mating connector's cam portion to ensure secure alignment and locking through intermeshing teeth and deflectable latches, facilitating easy connection and disconnection while providing strain relief.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rotatable cam member is used to assist connector mating, then ease of operation is improved, but reliability deteriorates due to potential relative rotation between the cam member and housing
Solution Approach 1:
The CPA member is pre-configured in the housing to engage with the cam member before mating occurs. This preliminary engagement ensures that when the cam member rotates during mating, it does so relative to a fixed reference point (the CPA member), preventing any unwanted relative rotation between the cam member and housing, thus maintaining connection reliability while preserving ease of operation
Solution Approach 2:
The CPA member acts as an intermediary between the housing and the cam member. It provides a stable engagement interface that mediates the rotational motion of the cam member, ensuring that the rotation is controlled and does not compromise the connection between the connector and housing, thereby resolving the contradiction between ease of operation and reliability
2Reliability
If a slide with latches is used to secure the connector, then reliability is improved, but device complexity increases
Solution Approach 1:
The first and second latches are combined into a single slide component that moves simultaneously to engage both latches with their respective receptacles. This merging of multiple securing functions into one integrated component achieves reliable connection security while minimizing the increase in device complexity by reducing the number of independent moving parts

AI summary
An electrical connector including a housing; a slide slidably mounted to the housing, wherein the slide comprises a rack section with teeth; a cam member and a connector position assurance (CPA) member. The cam member is rotatably mounted to the housing. The cam member comprises a caming surface adapted to contact a cam portion of a mating electrical connector. The cam member comprises a gear section with teeth engaging the teeth of the slide. The CPA member is movably connected to the housing. The CPA member is adapted to directly engage the cam member for preventing the cam member for rotating relative to the housing.
