Biological Sensor Connector with Metal Cover and Grounding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional biological information measurement connectors are prone to defective connections due to foreign matter entering through the upper face opening, and risk damage from static electricity during sensor insertion.
Innovation Solution
A resin-molded connector with a metal upper cover to prevent foreign matter entry and ground connection pieces to dissipate static electricity, ensuring secure connections and protecting against static damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the upper face opening is provided in the frame for positioning and holding the connection terminal, then the connection terminal can be properly positioned and held in the mold, but foreign matter may enter through the opening and cause defective connection
Solution Approach 1:
A cover member is introduced as an intermediary component between the external environment and the connection terminal. This cover member includes a cover body that fits over the frame and a cover cap that seals the opening, preventing foreign matter from reaching the connection terminal while allowing the connection terminal to remain properly positioned during manufacturing
Solution Approach 2:
The protective cover is divided into two segments: a cover body portion that covers the peripheral surface of the frame and a cover cap portion that closes the opening. This segmentation allows the cover to both protect the connection terminal and facilitate manufacturing processes
2Ease of manufacture
If the connection terminal is molded integrally with the frame, then manufacturing is simplified, but the front end of the connection terminal is not embedded in the resin requiring additional holding structures
Solution Approach 1:
The cover body is designed to serve multiple functions: it protects the connection terminal from foreign matter, provides structural support for the opening, and facilitates the molding process by defining the cavity shape. This multi-functionality reduces the need for additional separate components
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
Prevents foreign matter from reaching the connection terminal, reducing the risk of defective connections and protects measurement components from static electricity damage.
Implementation Method 1
a metal upper face cover that covers the upper face opening is mounted on the upper face opening of the frame
Implementation Method 2
a bent piece that is inserted into a bent piece insertion hole provided to the second edge of the frame is provided to a portion of the upper face cover on the side of the sensor insertion port, and ground connection pieces formed by extending the outside of the left and right sides of the frame from the upper face toward the lower face are provided in portions of the upper face cover opposite the left and right edges of the frame
