Connector Anchoring Terminals Guide Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector sets face the risk of damaging connection terminals during coupling due to excessive force applied during positioning, as the reinforcing fittings do not effectively contribute to positioning in both the longer and shorter directions, leading to terminal scraping.
Innovation Solution
A connector set design where the first and second connectors have anchoring terminals connected to a ground potential, with contact portions forming a rectangular ring shape, allowing the anchoring terminals to guide the connectors and reduce the force on connection terminals, thereby preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the first connector engages with the second connector using two first reinforcing fittings located at both ends of the first housing in the longer direction, then positioning in the longer direction is achieved, but positioning in the shorter direction is not achieved, causing the first terminals to scrape against the second terminals and placing large force on the terminals
Solution Approach 1:
The invention divides the positioning function into two separate components: the first reinforcing fittings handle positioning in the longer direction, while the second reinforcing fittings (added at both ends in the shorter direction) handle positioning in the shorter direction. This segmentation ensures that terminals are not forced to perform positioning functions, eliminating scraping and excessive force.
Solution Approach 2:
The reinforcing fittings are designed to serve dual purposes: providing structural reinforcement to the housing and enabling precise positioning in both longer and shorter directions. By making the fittings multi-functional, the invention eliminates the need for terminals to contribute to positioning, thereby preventing terminal damage.
2Measurement precision
If the first terminals and second terminals are used for positioning in the shorter direction, then positioning is achieved, but the terminals scrape against each other and are subjected to large force, risking terminal damage
Solution Approach 1:
The positioning function is segmented from the terminal function. Second reinforcing fittings are added specifically for shorter direction positioning, separating the positioning role from the terminal role. This ensures terminals only perform their electrical connection function without scraping or excessive force.
Solution Approach 2:
The second reinforcing fittings act as intermediary components that facilitate positioning in the shorter direction without involving the terminals. These fittings serve as mediators between the connectors, enabling accurate positioning while protecting terminals from damage.
3Device complexity
If only two reinforcing fittings are used at both ends of the first housing, then the structure is simple, but positioning in both directions is not achieved, leading to terminal damage
Solution Approach 1:
The invention introduces asymmetry in the distribution of reinforcing fittings by adding second reinforcing fittings at both ends of the first housing in the shorter direction, complementing the existing first reinforcing fittings in the longer direction. This asymmetric arrangement ensures comprehensive positioning in both directions while maintaining structural simplicity.
Solution Approach 2:
The reinforcing fittings are designed as multi-functional components that provide both structural reinforcement and precise positioning in both longer and shorter directions. By making the fittings universal, the invention achieves reliable terminal protection without significantly increasing structural complexity.

AI summary
An outer peripheral surface of a first anchoring terminal has a first surface facing one side of a second direction and a second surface facing one side of a third direction in a first corner portion, and a third surface facing the other side of the second direction and a fourth surface facing the other side of the third direction in a second corner portion. An inner peripheral surface of a second anchoring terminal has a fifth surface facing the other side of the second direction and a sixth surface facing the other side of the third direction in the first corner portion, and a seventh surface facing the one side of the second direction and an eighth surface facing the one side of the third direction in the second corner portion. The first to fourth surfaces make contact with the fifth to eighth surfaces, respectively.
