Solution Overview

Problem

Conventional bidirectional insertion connectors are limited to USB2.0 specifications, are difficult to manufacture due to soldering requirements, and suffer from high electromagnetic and radio frequency interference, making them unsuitable for advanced connectors like USB3.0 and Type-C.

Innovation Solution

The connector features a transmission conductor group with alternating contacts and soldering-free adaption sections, a shielding housing, a separation board, and an annular band to enable bidirectional insertion and reduce interference, using a frame and inclined lid for structural strength and noise suppression.

Solution Approach 1:

The patent employs elastic adaption sections that can deform within an elastic range to accommodate alternating contact arrangements. By utilizing elastic deformation parameters, the system tolerates manufacturing variations while maintaining proper electrical contact, reducing the stringency of manufacturing precision requirements for the alternating contact configuration.

Inventive Principle:

Solution Approach 1:

The patent extracts and isolates interfering electromagnetic fields by introducing dedicated shielding structures (annular band, framing members) and separation boards between transmission conductor groups. This extraction of harmful electromagnetic interference allows compact arrangement of multiple conductor groups while maintaining signal integrity through active shielding and physical separation.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

An electric connector includes at least one transmission conductor group, a plurality of contacts formed at an end of the transmission conductor group and up and down alternating each other, and adaption sections formed at an end of the transmission conductor group distant from the contacts and are arranged in groups each including at least four adaption sections juxtaposing each other. The transmission conductor group includes a plurality of high-frequency differential signal transmission conductor pairs, a plurality of power transmission conductor pair, and a plurality of low-frequency signal transmission conductors. With the above arrangement, the contact of the transmission conductor group is arranged in two rows alternating each other so that the insertion between the male and female connectors is directionless. The adaption sections are set in a secured juxtaposing configuration by means of an annular band to show the feature of soldering free and suppressing interference.
