Connector Temperature Sensor Elastic Pressing Arm Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors fail to maintain a stable contact state between the temperature sensor and the terminal due to vibrations, leading to potential gaps and ineffective overcurrent prevention in vehicle-mounted electronic devices.
Innovation Solution
A connector design featuring a housing with a base portion and elastically deformable pressing arm portions that maintain contact with the temperature sensor, allowing it to move and ensure consistent contact with the terminal, while a holding structure with locking projections and recesses secures the sensor in place, preventing misalignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the temperature sensor is fixed rigidly between holder members, then the contact state is stable, but the connector cannot adapt to vibrations and thermal expansion
Solution Approach 1:
The pressing arm portion is designed as an elastic component that can dynamically adjust its position. It extends from the base portion and presses the temperature sensor against the terminal, maintaining reliable contact while accommodating vibrations and thermal expansion through its elastic deformation capability.
Solution Approach 2:
The pressing arm portion changes its physical state between elastic deformation and rigid contact. When the connector experiences vibration or thermal expansion, the pressing arm elastically deforms to maintain contact pressure, ensuring the temperature sensor remains firmly contacted with the terminal throughout operational variations.
2Adaptability or versatility
If the temperature sensor is held loosely, then the connector can adapt to vibrations, but the contact state becomes unstable and gaps may form
Solution Approach 1:
The pressing arm portion provides dynamic adaptation through elastic deformation. It maintains continuous contact with the temperature sensor while accommodating vibrations and positional variations, preventing gaps from forming during vehicle operation without requiring rigid fixation.
3Reliability
If a complex holding structure is used to secure the temperature sensor, then contact stability is improved, but the device complexity increases
Solution Approach 1:
The holding structure is segmented into functional components: the base portion provides support, the pressing arm portion provides elastic contact pressure, and the locking projection provides positional restraint. This segmentation allows each component to perform its specific function simply, avoiding the need for a complex integrated structure while maintaining contact stability.
Solution Approach 2:
The pressing arm portion acts as an intermediary between the base portion and the temperature sensor. It translates the structural support from the base into continuous contact pressure on the sensor, while the locking projection serves as an intermediary to prevent excessive movement, simplifying the overall holding mechanism.

Function Achieved in This Case
The connector effectively maintains contact between the temperature sensor and terminal, ensuring accurate temperature detection and preventing overcurrent supply to electronic devices, even under vehicle vibrations, by utilizing elastic deformation and locking mechanisms to secure the sensor's position.
Implementation Method 1
the pressing arm portion is elastically deformable in the first orthogonal direction orthogonal to the contact direction, the pressing arm portion has a protrusion portion that protrudes into the space portion and comes into contact with the temperature sensor, and when the protrusion portion comes into contact with the temperature sensor, the pressing arm portion is elastically deformed to press the temperature sensor

AI summary
A connector includes a terminal, a housing, a temperature sensor, and a holding structure. The holding structure holds the temperature sensor so as to be movable in at least a first orthogonal direction in a space portion (housing formation space portion). The housing has the base portion and the pressing arm portion extending from the base portion in the contact direction and elastically deformable with respect to the first orthogonal direction orthogonal to the contact direction. The pressing arm portion has a protrusion portion that protrudes into the space portion and comes into contact with the temperature sensor. When the protrusion portion comes into contact with the temperature sensor, the pressing arm portion is elastically deformed to press the temperature sensor located in the space portion with respect to the first orthogonal direction, and the pressed temperature sensor is brought into contact with the terminal.
