Terminal Head Plug-In Connectors for Sheath Temperature Sensor Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional terminal heads for sheath type temperature sensors face difficulties in replacing the sensors due to the challenge of removing and reconnecting thin or thick leads from the sensor wiring terminals, which requires skilled labor and increases replacement costs, especially when the terminal plate needs to be replaced.
Innovation Solution
A terminal head design featuring a removable terminal plate and plug-in connectors with elastic coupling mechanisms, such as recessed portions and hook-shaped arms, allows for easy replacement of the sheath type temperature sensor without the need for on-site lead removal and connection, minimizing the number of replaced parts and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the terminal plate is fixed to the outer frame body with multiple fixing screws, then the connection stability is improved, but the replacement complexity increases due to the need to remove and reconnect leads
Solution Approach 1:
The terminal plate is segmented from the outer frame body through a detachable connection mechanism. The terminal plate can be independently removed from the outer frame body without requiring removal of fixing screws, enabling easy replacement of the temperature sensor while maintaining stable connections during operation.
2Reliability
If the leads are thin or thick, then the electrical connection capability is improved, but the operation difficulty increases due to challenges in removing and reconnecting leads
Solution Approach 1:
The terminal plate is pre-configured with terminal fittings that are already connected to the leads before installation. This preliminary arrangement eliminates the need for on-site lead removal and reconnection operations, as the entire terminal plate assembly can be replaced as a single unit while maintaining reliable electrical connections.
3Reliability
If the terminal plate is replaced along with the sensor, then the connection reliability is improved, but the replacement cost increases due to unnecessary part replacement
Solution Approach 1:
The terminal plate is designed as a separate, independently replaceable component that can be detached from the outer frame body. This segmentation allows replacement of only the temperature sensor without replacing the terminal plate, reducing material loss and replacement costs while maintaining connection reliability through the detachable connection mechanism.

AI summary
A terminal head, which is provided in a sheath type temperature sensor and is for connecting the sheath type temperature sensor and a cable, is structured such that, in order for replacement of the sheath type temperature sensor to be easily performed and in order to minimize the number of replacement parts, a terminal plate (2) of the terminal head (1) and the sheath type temperature sensor 3 are coupled using a pair of plug-in connectors (4, 5) and the coupling is held by a coupling nut (6). When replacing the sheath type temperature sensor (3), the leads (31) of the sheath type temperature sensor do not need to be detached from and attached to the terminal plate (2) at the replacement worksite, and the only replaced part other than the sheath type temperature sensor (3) is the one connector (5).
