Socket Contact Spring Cage for Out-of-Round Contact Boxes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing socket contacts in plug connectors face challenges in adapting to out-of-roundness of contact boxes, leading to suboptimal contact performance.
Innovation Solution
The socket contact design incorporates a single-side spring cutout on each contact spring at the rear collar, allowing contact via spring points to the main body, and direct contact via rigidly embossed domes and the radial inner surface of the main body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a conventional socket contact design is used with full connection between rings and springs, then structural stability is improved, but adaptability to out-of-roundness of contact boxes deteriorates
Solution Approach 1:
The contact spring is segmented into two distinct groups: a first group of springs fully connected to both rings for structural stability, and a second group of springs with single-side connection to adapt to out-of-roundness. This segmentation allows each group to fulfill its specific function independently, resolving the contradiction between stability and adaptability.
Solution Approach 2:
Different local regions of the contact spring structure are given different connection properties. The first group of springs has full connection (rigid, stable) while the second group has single-side connection (flexible, adaptive). This local differentiation allows the overall structure to simultaneously achieve both stability and adaptability.
2Strength
If contact springs are fully connected to both rings, then mechanical strength is improved, but radial freedom of movement deteriorates
Solution Approach 1:
The contact springs are divided into two groups with different connection configurations. The first group provides mechanical strength through full connection, while the second group provides radial freedom of movement through single-side connection, allowing both requirements to be satisfied simultaneously.
Solution Approach 2:
The contact spring structure incorporates dynamic characteristics by allowing the second group of springs to move radially with greater freedom. This dynamic capability enables the contact springs to adapt to variations in contact box geometry while maintaining overall structural integrity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances contact reliability by accommodating out-of-roundness of contact boxes and improves radial freedom of movement, leading to better plug connection stability and performance.
Implementation Method 1
a single-side spring cutout of each, in particular second, contact spring is provided at the rear collar (also referred to as a ring), wherein contact is made (in particular via contact points) via the spring to the main body

AI summary
The invention relates to a contact partner, in particular a socket contact, which can be plugged together with a pin contact to form a plug-in connection. The socket contact is in the form of a punched rolled part and has a contact region and a crimp region. The contact region is formed by a circumferential housing. Two mutually spaced rings are provided within the housing, which rings are connected to each other by at least one elongate contact spring. A single-side spring cutout of each contact spring is provided at the rear collar. Contacting takes place by means of the spring to the main body, whereby the contacting takes place radially by means of the rigidly embossed contact domes on the outer face of the collar of the spring, and also takes place directly by means of the radial inner surface of the main body.
