Inverter Connector Guide With Integrated Temperature Sensor Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Assembling electrical inverters is complex due to the precise positioning and orientation of control pins from power modules relative to female connectors on electronic boards, and integrating temperature sensors in this environment is further complicated by the stacked nature of inverter components.
Innovation Solution
A connector guide with a substantially flat rigid body and calibrated orifices for precise alignment of control pins, along with an intermediate portion for housing a temperature sensor, simplifies the assembly process by ensuring correct pin positioning and sensor placement in a single part.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate temperature sensor assembly is used, then temperature measurement capability is added, but device complexity and assembly difficulty increase
Solution Approach 1:
The temperature sensor housing is integrated into the connector guide body, combining two previously separate components (connector guide and temperature sensor housing) into a single unified structure. This merging eliminates the need for separate assembly steps and reduces overall device complexity while maintaining temperature measurement functionality.
Solution Approach 2:
The connector guide body is designed to serve multiple functions: guiding control pins during assembly and housing the temperature sensor. This multi-functionality reduces the number of separate components needed and simplifies the overall assembly process.
2Manufacturing precision
If precise positioning of control pins is ensured through calibrated orifices, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The connector guide body is designed with segmented functional zones: calibrated orifices for pin positioning, a receiving area for the temperature sensor, and structural support portions. This segmentation allows each feature to be optimized independently while maintaining overall simplicity.
Solution Approach 2:
The calibrated orifices are pre-formed in the connector guide body during manufacturing, establishing precise control pin positions before assembly. This preliminary positioning action ensures manufacturing precision without requiring complex adjustment mechanisms during assembly.
3Reliability
If temperature sensor is accessed through stacked components, then temperature measurement is enabled, but ease of operation deteriorates
Solution Approach 1:
By integrating the temperature sensor housing into the connector guide body, the sensor becomes accessible through the same assembly path as the control pins. This eliminates the need to navigate through stacked components separately, improving ease of operation during assembly.

AI summary
The invention relates to a connector guide for an inverter comprising at least two power modules (28), namely at least a first power module and a second power module, the connector guide (1) comprising a substantially flat rigid body (2) in which orifices (5) are formed for the passage of control pins (8) for the power modules (28), said orifices (5) being calibrated and positioned in such a way as to conform to the position and orientation of said control pins (8). The body of the connector guide comprises a so-called intermediate portion (13) which is intended to be positioned between the first power module and the second power module, the intermediate portion (13) comprising a housing (15) suitable for accepting a temperature sensor (16). The connector guide thus makes it possible to ensure that the power modules control pins are correctly positioned while at the same time also ensuring the positioning and retention of the temperature sensor.
