General assembly type seven-pin USB (Universal Serial Bus) socket, plug and connector assembly

Abstract

A general assembly type seven-pin USB (Universal Serial Bus) socket comprises a socket body, seven socket terminals and a cover body; the seven socket terminals are integrally formed in the socket body; the cover body coats the periphery of the socket body; the socket body comprises a base portion, a first tongue plate and a second tongue plate; the first tongue plate is formed by forward extension from the base portion; the second tongue plate is formed by forward extension from the first tongue plate; the horizontal bilateral sides of the first tongue plate extend outward to form two side portions; the socket terminals comprise five conventional socket terminals and two additional socket terminals; the five conventional socket terminals penetrate the base portion and the first tongue plate to extend to the second tongue plate; the two additional socket terminals penetrate the base portion and extend to the two side portions of the first tongue plate; the seven-pin USB socket is compatible with the abutting connection type improved seven-pin USB plug and a conventional five-pin USB plug. The general assembly type seven-pin USB socket can be compatible with the different plugs.

Description

[0001] technical field [0002] The invention relates to an input and output electrical connector, in particular to a universal seven-pin USB socket, a seven-pin USB plug and a connector assembly thereof. Background technique [0003] Micro-USB has become the standard interface of mobile terminals at present, but the styles of mobile terminals are various, and the requirements for functions are also different. In the development and design of some mobile phone terminals, in order to achieve a more powerful transmission function, the traditional five-pin Micro-USB interface function can no longer meet the demand. If other types of interfaces with strong transmission functions are developed, it will cause mobile phone The terminal is incompatible with most existing accessories, isolating the mobile terminal from the market and violating mandatory standards in some regions. [0004] The conventional standard Micro-USB is a five-pin design, including a pair of signal terminals,...

AI Technical Summary

Problems solved by technology

In the development and design of some mobile phone terminals, in order to achieve a more powerful transmission function, the traditional five-pin Micro-USB interface function can no longer meet the demand. If other types of interfaces with strong transmission functions are developed, it will cause mobile phone The terminal is not compatible with most existing accessories, which isolates the mobile terminal from the market and violates mandatory standards in some regions

[0004] The conventional standard Micro-USB is a five-pin design, including a pair of signal terminals, a power transmission terminal, a ground terminal, and an ID terminal; however, due to the small size of the Micro-USB interface, the width and thickness of each conductive terminal Not much, when the current needs to pass too much, the small cross-sectional area of ​​the conductive terminal makes the passability insufficient;

[0005] If a Micro-USB electrical connector assembly can be developed so that it is compatible with traditional Micro-USB connectors and can improve transmission capabilities at the same time, it can solve the contradiction between product isolation and mandatory regulations and performance requirements to the greatest extent.
