Compressor Stator Carrier Element Connector Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrically driven compressors for refrigerant circuits in climate control systems face challenges during assembly due to the connector housing's tendency to detach and oscillate, causing material abrasion and requiring time-consuming repositioning, which complicates the assembly process and increases production costs.
Innovation Solution
A device with a carrier element integrated into the stator, featuring a receiving element for the connector housing and a rotation lock system, ensures the connector housing is fixed in a predefined position, preventing relative movements during assembly and operation, utilizing a combination of form-closure connections and resilient pressure elements to secure the carrier element to the stator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the connector housing is secured by pressing it onto the stator insulation, then the assembly process is simple, but the connector housing becomes detached and oscillates during operation causing material abrasion
Solution Approach 1:
The connector housing is divided into two functional parts: a pressing-in portion that attaches to the stator insulation (maintaining assembly simplicity) and a rotation prevention portion that engages with the carrier element (ensuring operational stability). This segmentation allows each part to fulfill its specific function without compromising the other.
Solution Approach 2:
The carrier element is pre-positioned on the stator insulation before the connector housing is installed. The receiving element of the carrier element is prepared in advance to receive and secure the rotation prevention portion of the connector housing, ensuring correct positioning and preventing oscillation from the start of operation.
2Reliability
If the connector housing is fixed in a predetermined position, then relative movement and material abrasion are prevented, but the assembly process becomes more complex
Solution Approach 1:
The carrier element merges two functions into a single component: it serves as both the mounting base on the stator insulation and the rotation prevention mechanism. The receiving element integrated into the carrier element combines the positioning and securing functions, simplifying the overall assembly process while ensuring stability.
Solution Approach 2:
The rotation lock system is designed to automatically engage when the connector housing is pressed onto the stator insulation. The form-closure connection between the rotation prevention portion and receiving element self-activates during the pressing-in process, preventing rotation without requiring additional assembly steps or external intervention.
3Ease of operation
If the connector housing can be positioned in different dispositions, then assembly flexibility is improved, but incorrect positioning leads to time expenditures for repositioning
Solution Approach 1:
The rotation prevention portion and receiving element are designed with asymmetric geometries that only fit together in one specific orientation. This asymmetric design provides built-in positioning guidance, allowing the connector housing to be correctly positioned in a single attempt without requiring trial-and-error repositioning, thus eliminating time losses while maintaining assembly flexibility.

AI summary
A device for driving a compressor of a gaseous fluid, in particular an electric motor. The device comprises a rotor and a stator which are disposed extending along a common longitudinal axis. A carrier element is disposed in contact on a first end side, oriented in an axial direction, of the stator, which carrier element is developed as a coherent unit and integral component with at least one receiving element for a connector for receiving at least one plug connector. In the axial direction the carrier element is in contact with a cylindrical wall on an insulation element fixedly connected with the stator and comprises an axially oriented annular surface.
