A socket design featuring a heat transfer member with an opening for a rod-like temperature sensor, where the sensor's tip end portion contacts the electrical component while being spaced apart from the heat transfer member by an air layer, reducing heat transfer and improving sensing accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a heat insulation material is interposed between the temperature sensor and the heat transfer member, then the thermal effect on the temperature sensor is reduced, but heat can still be transferred through solid portions of the insulation material causing temperature sensing errors
Solution Approach 1:
The patent introduces air as an intermediary substance between the temperature sensor and heat transfer member. By forming an air layer through the recess structure, heat transfer via conduction is minimized since air has low thermal conductivity, thereby reducing thermal interference while maintaining sensor functionality
Solution Approach 2:
The patent applies local quality by creating a recess structure specifically at the position where the temperature sensor contacts the heat transfer member. This localized modification introduces an air layer only at the critical interface, providing thermal insulation precisely where needed without affecting other functional areas
2Device complexity
If the temperature sensor is placed in direct contact with the heat transfer member, then temperature measurement is simplified, but the sensor is affected by heat emitted from the heat transfer member causing measurement errors
Solution Approach 1:
The patent modifies the heat transfer member by creating a recess at the specific location where the temperature sensor makes contact. This localized structural change introduces an air layer interface without fundamentally altering the overall direct-contact configuration, maintaining simplicity while improving measurement accuracy
Solution Approach 2:
The recess structure creates an air layer that acts as a thermal intermediary between the sensor and heat transfer member. This air medium reduces direct thermal conduction while allowing the sensor to remain positioned at the contact interface, preserving measurement functionality while reducing thermal interference

AI summary
An IC socket includes: a heat transfer member attached to a socket body in a manner capable of contacting an electrical component and having an opening penetratingly formed at a contact surface that contacts the electrical component accommodated in the socket body; and a temperature sensor that is mounted in the opening of the heat transfer member and has a rod-like tip end portion including a thermosensitive element and extending toward the electrical component, in which the tip end portion, as well as the heat transfer member, contacts the electrical component. In the IC socket, a tubular component having an insertion hole in which an outer surface of a portion of the temperature sensor other than the tip end portion is fitted in a slidable manner in the axial direction of the temperature sensor, is attached to the opening.
