Abstract
Abstract An electrical connector for electrically connecting an exterior mating connector to a circuit board, mainly comprises an insulative housing, a shell means and a plurality of contacts. The insulative housing includes a plurality of walls wherein the top wall and the opposing lateral walls thereof each form a first retention. The shell means includes a plurality of surfaces wherein the top surface and the opposing lateral surfaces each form a second retention for being retained with said first retentions of the housing. Accordingly, the retentive effect between the shell means and the housing is enhanced. Additionally, the shell means further includes a pair of grounding portions each consisting of a connecting section, an engaging section and a protrusion for providing a grounding function wherein the protrusion enlarges a solder contact area with a soldering paste pre-coated on a surface of the circuit board for further enhancing the retention between the shell means and the circuit board.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
136 words
An electrical connector for electrically connecting an exterior mating connector to a circuit board, comprising: an insulative housing including a plurality of walls and receiving a plurality of contacts therein; a shell means including a plurality of surfaces; a grounding portion including a connecting section for joining the grounding portion with shell means, and engaging section providing an increased solder contact area to engage with a soldering paste pre-coating on a surface of the circuit board for soldering the grounding portion onto the circuit board, and a protrusion upward extending from said engaging section opposite the connection section along a vertical direction parallel to a lateral surface of said shell means and providing an additional enlarged solder area to engage with the soldering paste for enhancing the retention between the grounding portion and the circuit board.
Claim 2
Dependent Claim
136 words
An electrical connector for electrically connecting an exterior mating connector to a circuit board, comprising: an insulative housing including a plurality of walls and receiving a plurality of contacts therein; a shell means including a plurality of surfaces; a grounding portion including a connecting section for joining the grounding portion with shell means, and engaging section providing an increased solder contact area to engage with a soldering paste pre-coating on a surface of the circuit board for soldering the grounding portion onto the circuit board, and a protrusion upward extending from said engaging section opposite the connection section along a vertical direction parallel to a lateral surface of said shell means and providing an additional enlarged solder area to engage with the soldering paste for enhancing the retention between the grounding portion and the circuit board.
Claim 3
Dependent Claim
23 words
The electrical connector as described in claim 1, wherein the engaging section of the grounding portion is configured to be a horizontal plate.
Claim 4
Dependent Claim
92 words
An electrical connector for electrically connecting an exterior mating connector to a circuit board, comprising: an insulative housing having a mating slot for receiving the exterior mating connector therein; a shell means having a plurality of surfaces wherein a continuous extension surrounds a border of an opening defined on one of the surfaces to be fully conformably received within the mating slot of the housing to provide a grounding connection with a shell of the exterior mating connector, wherein the extension is rearwardly extruded from a front surface of the shell means.
Claim 5
Dependent Claim
92 words
An electrical connector for electrically connecting an exterior mating connector to a circuit board, comprising: an insulative housing having a mating slot for receiving the exterior mating connector therein; a shell means having a plurality of surfaces wherein a continuous extension surrounds a border of an opening defined on one of the surfaces to be fully conformably received within the mating slot of the housing to provide a grounding connection with a shell of the exterior mating connector, wherein the extension is rearwardly extruded from a front surface of the shell means.
Claim 6
Dependent Claim
23 words
