Abstract
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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
234 words
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.
Claim 2
Dependent Claim
234 words
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.
Claim 3
Dependent Claim
212 words
An electrical connector comprising: an insulative housing having a base and a mating tongue extending forwardly from a front face of the base, the mating tongue defining a plurality of receiving passageways arranged in a row in a face thereof with a middle receiving passageway and side receiving passageways beside the middle receiving passageway; and a plurality of terminals received in the housing with a grounding terminal received in the middle receiving passageway and signal terminals received in the side receiving passageways, each terminal defining a recess in a front edge thereof fittingly receiving a protrusion projecting rearwardly from the mating tongue into the corresponding receiving passageways to fix a contacting portion of the terminal to the mating tongue; wherein the base of the insulative housing comprises a side slot 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; wherein the middle receiving passageway is longer than the side receiving passageway and the grounding terminal is longer than the signal terminals.
