Electrical Connector Positioning Member Elastic Buckling Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electrical connector design faces difficulties in assembly due to the need for a strong force to secure the soldering leg positioning member, which can lead to loose connections and instability, as the buckling strength between the engagement blocks and limiting slot is weak.
Innovation Solution
The design incorporates two elastic buckling portions extending from the positioning member through a shielding sheet, which reduces assembly force requirements and enhances stability by increasing the buckling strength through a reserved space that allows the second buckling portion to attach to a first buckling portion inside a positioning slot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If engagement blocks are used to fix the positioning member to the insulating body, then the positioning member can be assembled, but the buckling strength is weak and the positioning member easily becomes loose
Solution Approach 1:
The positioning member is divided into multiple segments: the main body, engagement blocks for lateral fixation, and elastic buckling portions for vertical fixation. This segmentation allows each part to perform its specific function optimally - engagement blocks provide easy lateral assembly while buckling portions provide reliable vertical retention
Solution Approach 2:
The engagement blocks are nested within corresponding slots on the insulating body, creating a layered fixation system where lateral engagement provides initial positioning and vertical buckling provides additional retention, solving both assembly ease and connection stability requirements
2Reliability
If strong force is applied to push engagement blocks into the limiting slot, then the positioning member can be fixed, but the assembly difficulty increases
Solution Approach 1:
The elastic buckling portions are designed to be flexible during assembly, allowing them to bend and pass through the shielding sheet with minimal force. After assembly, they return to their original shape, providing strong fixation. This dynamic property resolves the contradiction between easy assembly and strong fixation
Solution Approach 2:
The elastic buckling portions change their physical state during assembly - from a flexible, deformable state during insertion to a rigid, force-providing state after assembly. This parameter change allows easy assembly followed by strong fixation without requiring excessive force during the assembly process

AI summary
An electrical connector includes an insulating body having a base and a tongue protruding from the base, a metal casing surrounding the insulating body, multiple terminals grouped into upper and lower rows and fixedly at the insulating body, a shielding sheet disposed at the insulating body and located between the upper and lower rows of terminals, and a positioning member. A positioning slot is disposed at the base. A first buckling portion is disposed inside the positioning slot. Each terminal has a contact portion extending forward and exposed partially from the tongue, and a soldering portion extending backward out of the base. The shielding sheet has a reserved space corresponding to the positioning slot. The positioning member has multiple positioning holes for positioning the soldering portions, and a second buckling portion passing through the reserved space and fixed to the first buckling portion.
