First Claim
Patent Images
1. An electrical connector comprising:
- an insulative housing having at least three receiving passageways arranged in one row with a middle receiving passageway being longer than other two side receiving passageways;
at least three terminals comprising a grounding terminal and two signal terminals being correspondingly received in the receiving passageways, wherein the grounding terminal has a length longer than the two signal terminals and is received in the middle receiving passageway, and the signal terminals are received in the two side receiving passageways; and
a metal shield enclosing the insulative housing and having a pair of inward projections;
wherein the housing forms at least three protrusions projecting into the receiving passageways and mating with recesses defined in a front edge of each terminal for securing a front end portion of the terminals to the housing;
wherein the insulative housing has a base and a mating tongue projecting from the base having the receiving passageways defined in a face thereof;
wherein the base of the insulative housing comprises a side slot for receiving said inward projections and a plurality of through holes communicating with the receiving passageways, respectively;
wherein each terminal has a retaining portion received in a corresponding through hole and the retaining portion forms barbs biting into the housing;
wherein each terminal has a soldering portion integral with retaining portion and extending out of the corresponding hole for soldering to a printed circuit board.

Abstract
A universal serial bus (USB) connector (100) includes a row of terminals (20) fixedly received in receiving passageways (13) defined in a face of a mating tongue (12) of an insulative housing (10) of the connector. The terminals include a middle grounding terminal (21) which is longer than two signal terminals (23) beside the grounding terminal. The mating tongue forms protrusions (141) projecting rearwardly into recesses (204) defined in a front edge of each terminal thereby securing the terminals to the mating tongue.
