Electrical Connector Housing With Positioning Posts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional circuit board connectors require the entire housing and terminal module to be mounted as a single unit, leading to increased complexity in the mounting process, which complicates assembly and increases manufacturing and maintenance costs.
Innovation Solution
The electrical connector design features a housing with an accommodating chamber and positioning posts that allow for separate assembly and mounting of the terminal module to a printed circuit board, enabling easier assembly and reducing complexity by allowing the housing to be rotated and positioned accurately, with the terminal module being inserted into the chamber and secured using positioning posts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the housing and terminal module are integrated and mounted as a single unit, then the structural integrity is maintained, but the mounting complexity increases
Solution Approach 1:
The electrical connector is divided into separate components: a housing and a terminal module. The terminal module can be mounted to the circuit board independently, and the housing is subsequently assembled around it. This segmentation reduces mounting complexity while maintaining structural integrity through the housing's accommodating chamber and positioning posts.
2Ease of manufacture
If the housing is designed with an integrated terminal module, then the structural strength is improved, but the ease of manufacture decreases
Solution Approach 1:
The connector is manufactured in separate parts (housing and terminal module) that can be produced independently using optimized processes, then assembled together. The positioning posts and accommodating chamber ensure the assembled structure maintains sufficient strength.
Solution Approach 2:
The terminal module is nested within the housing's accommodating chamber. The housing encloses and protects the terminal module while allowing for independent manufacturing and assembly of the components.
3Ease of repair
If the housing and terminal module are mounted together, then the reliability of connection is improved, but the ease of repair deteriorates
Solution Approach 1:
The terminal module can be removed and replaced independently from the housing, enabling easier repair and maintenance. The positioning posts and accommodating chamber design ensure that the connection remains reliable while allowing for component separation when needed.

AI summary
An electrical connector comprises a housing and a terminal module. The housing has a top portion, a bottom portion and two side portions connecting the top portion and the bottom portion. The top portion, the bottom portion and the two side portions form an accommodating chamber and the terminal module is accommodated in the accommodating chamber. The two side portions have positioning posts preventing horizontal displacement of the housing relative to the terminal module, and the top portion and the bottom portion prevent vertical displacement of the housing relative to the terminal module. Methods of assembling the electrical connector are also provided.
