Connector Assembly With Split Pitch Positioning for Faster Molding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of connectors with a contact pitch greater at the contact face than at the exit face is laborious and time-consuming due to the need for complex inlay molding processes.
Innovation Solution
A connector assembly comprising a separate housing part for the exit face and a positioning part for the contact face, allowing for simpler injection molding of the housing without embedded contact elements, with the positioning part attached later to set the contact pitch and enhance mechanical stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If contact elements are embedded in the housing part using inlay molding, then the pitch at the contact face can be greater than at the exit face, but the production process becomes laborious and time-consuming
Solution Approach 1:
The connector is divided into separate components: a housing part formed by simple injection molding and a positioning part that defines the contact face pitch. These parts are produced separately and then assembled together, eliminating the need for complex inlay molding while maintaining the required pitch variation.
Solution Approach 2:
The positioning part is prepared in advance with the correct pitch geometry for the contact face. This positioning part is then attached to the housing part in a separate assembly step, allowing the housing to be produced quickly through simple injection molding without time-consuming embedded contact element processes.
2Manufacturing precision
If contact elements are embedded in the housing part, then the pitch can be controlled, but the manufacturing process becomes complex
Solution Approach 1:
The function of defining the contact face pitch is extracted from the housing part and assigned to a separate positioning part. This allows the housing part to be manufactured through simple injection molding without embedded contact elements, while the positioning part separately provides the precise pitch control needed at the contact face.
Solution Approach 2:
The connector assembly is segmented into a housing part and a positioning part with distinct functions. The housing part provides structural support and guidance, while the positioning part specifically defines the contact face pitch, simplifying the manufacturing of each component while maintaining overall precision.
3Productivity
If the housing part is produced without contact elements in the cavity, then production time is reduced, but the contact face pitch must be established separately
Solution Approach 1:
The positioning part is designed and prepared in advance with the correct pitch geometry. This allows the housing part to be quickly produced through simple injection molding without time-consuming embedded contact element processes. The positioning part is then attached in a subsequent assembly step to establish the contact face pitch.
