Electrical Connector Terminal Structure for Centered Stable Mating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors suffer from mounting deviations due to gaps between the contact body and the power contact slot, leading to oblique insertion and impaired signal transmission.
Innovation Solution
The electrical connector assembly features terminals with a fixing portion, neck portion, and contact arms that allow for stable clamping and centering, utilizing protruding portions to interfere with the terminal slot walls, ensuring proper alignment and contact with the mating component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the contact body is fixed laterally to the power contact slot through barbs, then the power contact is stably fixed in the shell, but a gap exists in the longitudinal direction causing oblique insertion during mounting
Solution Approach 1:
The power contact is divided into distinct functional segments: a fixing portion with barbs for lateral stability, a neck portion for flexibility, and contact portions for electrical connection. This segmentation allows each part to fulfill its specific function independently, resolving the contradiction between stability and alignment precision.
Solution Approach 2:
The neck portion is designed as a flexible connecting element between the fixing portion and contact portions. This dynamic structure allows the contact portions to self-adjust and compensate for oblique insertion during mounting, while the fixing portion remains stably fixed through the barbs interfering with the power contact slot.
2Stability of the object's composition
If the contact body is fixed laterally through barbs, then the power contact is stable, but the matching ends cannot follow lateral deviation when the substrate is obliquely inserted, resulting in gaps and poor conductivity
Solution Approach 1:
The neck portion serves as a dynamic flexible connection that allows the contact portions to swing and follow lateral deviations when the substrate is obliquely inserted. This maintains continuous electrical contact between the matching ends, ensuring reliable signal transmission while the fixing portion remains stably fixed.
Solution Approach 2:
The neck portion's flexibility parameter is optimized to allow sufficient lateral movement for compensating oblique insertion, while maintaining structural integrity. This parameter change enables the contact portions to adapt to misalignment without compromising the lateral fixation stability provided by the barbs.
3Adaptability or versatility
If gaps exist between the neck portion and terminal slot walls, then the contact body can accommodate oblique insertion, but the terminal may deviate during mounting
Solution Approach 1:
The terminal is segmented into a fixing portion for precise positioning and a neck portion for flexibility. The fixing portion includes protruding portions that interfere with the terminal slot walls to prevent lateral deviation during mounting, while the neck portion accommodates oblique insertion through its flexible nature.
Solution Approach 2:
The neck portion provides dynamic flexibility to accommodate oblique insertion, while the fixing portion with protruding portions maintains static positional precision. This combination allows the terminal to tolerate mounting variations without deviating from its intended position.

AI summary
An electrical connector, which is used to mate with a mating component. The electrical connector includes an insulating body, concavely provided with an insertion slot. A plurality of terminal slots are arranged along the longitudinal direction. Each terminal has a fixing portion. Two contact arms extend upward from the neck portion. The two contact arms protrude toward each other to form two contact portions protruding into the insertion slot. Along the longitudinal direction, the first protruding portion and the second protruding portions respectively interfere with two opposite inner walls of the corresponding terminal slots, such that the two contact portions of each terminal may stably clamp the mating component, and the terminal is inserted and centered into the corresponding terminal slot.
