Electrical Connector Support Structure for Miniaturized Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors face challenges in achieving both high structural reliability and miniaturization, as designs that enhance structural strength often result in longer insulating blocks, hindering miniaturization.
Innovation Solution
The electrical connector incorporates a cantilever-shaped first elastic arm with a supporting portion exposed from the first insulating block, along with a supporting block located behind the supporting portion, which improves structural reliability while shortening the insulating block length.

Engineering Contradiction Analysis
1Reliability
If the first fixing portion embedded in the first insulating block is designed to be longer to improve structural strength, then the structural reliability is improved, but the overall length of the first insulating block becomes longer which hinders miniaturization
Solution Approach 1:
The patent introduces a supporting block positioned behind the supporting portion of the elastic arm, creating a new spatial dimension for support. This allows the elastic arm to have sufficient embedded length for reliability without increasing the front-to-back length of the insulating block, as the support function is moved to a different location in space (behind the elastic arm rather than within the insulating block)
Solution Approach 2:
The patent divides the support function into two separate components: the insulating block provides initial support and positioning, while the supporting block provides additional support from behind. This segmentation allows each component to be optimized independently - the insulating block can be shortened for miniaturization while the supporting block compensates for structural reliability

AI summary
An electrical connector includes a first terminal module and a supporting block. The first terminal module includes a first insulating block and a number of first conductive terminals fixed to the first insulating block. At least one of the first conductive terminals includes a cantilever-shaped first elastic arm extending beyond the first insulating block and a supporting portion extending from the first elastic arm. The first elastic arm includes a first mating portion protruding forwardly along a mating direction and upwardly relative to the mating direction. The supporting portion is connected to the first mating portion. The supporting portion is exposed from the first insulating block. The supporting block is located behind the supporting portion along the mating direction and configured to abut against the supporting portion.
