Electrical Connector Terminal Positioning for Stable Bidirectional Mating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors face challenges in ensuring reliable contact between mating modules due to the inability of all elastic arms to be properly positioned, leading to potential poor contact and connectivity issues.
Innovation Solution
The electrical connector design includes an insulating body with strategically placed grooves adjacent to mating ports, allowing first and second elastic arms to extend into corresponding grooves for precise positioning and reliable contact with mating modules, enabling bidirectional plugging and improved connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If positioning grooves are provided only on one side of the insulating body, then the structure is simple, but not all elastic arms can be positioned reliably
Solution Approach 1:
The positioning grooves are segmented and distributed on different wall portions of the insulating body. Specifically, first positioning grooves are provided on a first wall portion and second positioning grooves are provided on a second wall portion, allowing elastic arms to be positioned at multiple locations rather than relying on a single集中 positioning structure.
Solution Approach 2:
Different wall portions of the insulating body are equipped with positioning grooves according to the specific positioning needs of different elastic arms. Each wall portion that requires positioning has corresponding grooves, while other portions maintain their original simple structure, achieving localized optimization without overall complexity increase.
2Manufacturing precision
If elastic arms extend into positioning grooves, then positioning precision is improved, but the risk of poor contact with mating module increases when positioning is incomplete
Solution Approach 1:
The positioning function is segmented across multiple wall portions. By providing positioning grooves on both the first wall portion and second wall portion, the system ensures that multiple elastic arms can be positioned simultaneously, eliminating the incomplete positioning problem that occurs when only one wall portion has grooves.

AI summary
An electrical connector includes an insulating body and a first terminal module. The insulating body includes a first receiving space, a first mating port and a second mating port. The insulating body includes a first wall portion having a number of first grooves and a second wall having a number of second grooves. The first terminal module is at least partially installed in the first receiving space. The first terminal module includes a number of first terminals. Each first terminal includes a first main body, a first elastic arm and a second elastic arm. The first elastic arm and the second elastic arm at least partially extend into a corresponding first groove and a corresponding second groove, respectively, so that the first elastic arm and the second elastic arm can be better positioned.
