Connector Temperature Sensor Holder Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors with temperature sensors face accuracy issues in temperature detection due to heat transfer from the sensor to the holder, leading to deviations in detected temperature from the actual temperature of the target.
Innovation Solution
The connector design includes a holder with first and second pressing portions that project towards the temperature sensor and the temperature detection target, respectively, forming a minimal contact area to reduce heat transfer and enhance accuracy, with the first pressing portions being configured for point-contact or line-contact with the sensor and the holder members engaging to maintain a close attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the temperature sensor is pressed to the temperature detection target (electric wire) on a wall surface, then the temperature sensor can detect temperature, but the contact area is large causing heat to escape to the holder member and reducing detection accuracy
Solution Approach 1:
The holder is divided into multiple holder members (first holder member and second holder member) that can be engaged with each other. This segmentation allows the temperature sensor to be pressed between the holder members with a minimized contact area, reducing heat transfer to the holder while maintaining detection accuracy.
Solution Approach 2:
The pressing portions of the holder members are designed to contact the temperature sensor at specific localized points rather than across a large surface area. This local quality approach minimizes the contact area between the sensor and holder, reducing heat escape while maintaining sufficient contact for accurate temperature detection.
2Measurement precision
If the temperature sensor is closely attached to the temperature detection target, then temperature detection accuracy is enhanced, but heat transferred from the target escapes to the holder member through larger contact area
Solution Approach 1:
The holder structure is segmented into multiple engageable holder members that create a夹持 (clamping) configuration. This allows the temperature sensor to be closely attached to the temperature detection target while limiting the sensor's contact area with the holder members themselves, thus reducing heat loss to the holder.
Solution Approach 2:
The holder members act as intermediary elements that transmit mechanical pressing force to ensure close attachment between the temperature sensor and the temperature detection target, while the design of these intermediaries (with limited contact areas) prevents excessive heat transfer from the target to the holder structure.

AI summary
A connector includes a terminal, a connector housing, a temperature sensor, and a holder. The connector housing houses the terminal. The temperature sensor defines the terminal or an electric wire connected to the terminal as a temperature detection target, and detects temperature of the temperature detection target. The holder houses and holds the terminal, the electric wire, and the temperature sensor. The holder includes at least one first pressing portion and a second pressing portion. The first pressing portion projects toward the housed temperature sensor, and presses and pushes the temperature sensor to the temperature detection target. The second pressing portion presses and pushes the housed temperature detection target to the temperature sensor.
