Socket Connector Protective Fitting Press-Fit Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost of manufacturing socket connectors due to the need for precise molds for insert molding, which inhibits cost reduction while ensuring the protective metal fittings are firmly held to the housing.
Innovation Solution
A manufacturing method for socket connectors that involves cutting a metal plate to form symmetrical protective parts, which are then press-fitted into the housing, eliminating the need for expensive molds and reducing production costs while ensuring secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If insert molding is used to integrate the housing and protective metal fittings, then the protective fittings are firmly held to the housing, but the manufacturing cost increases significantly due to high-dimensional-accuracy molds
Solution Approach 1:
The protective metal fitting is divided into multiple parts: a protective part covering the island end part, arm parts extending from the protective part, and press-fitting parts at the distal ends of the arm parts. This segmentation allows the fitting to be manufactured separately and assembled via press-fitting, eliminating the need for expensive insert molding while maintaining firm attachment.
2Stability of the object's composition
If insert molding is used to integrate the housing and protective metal fittings, then the protective fittings are firmly held to the housing, but the device complexity increases due to the integrated molding process
Solution Approach 1:

This segmentation allows the fitting to be manufactured separately and assembled via press-fitting, eliminating the need for expensive insert molding while maintaining firm attachment.
Solution Approach 2:
The press-fitting parts are formed in advance on the protective metal fitting during its manufacturing process. This preliminary formation of attachment features simplifies the final assembly process and reduces the complexity of the overall manufacturing system compared to integrated molding.

AI summary
A socket connector includes a socket housing in which an island part and a peripheral wall surrounding the island part project upward from a bottom plate, a plurality of socket contacts arranged in the socket housing, and two protective metal fittings. In a cutting step, a half-dome part of the two protective metal fittings is formed by cutting a metal plate in such a way that a dome part in a symmetrical shape formed by drawing in the metal plate is split into two halves along a line of symmetry. In a press-fitting step, two press-fitting parts of each socket hold-down are press-fit into two long walls, respectively.
