Abstract
A receptacle connector with a metal housing encircling an insulative housing with a slot to receive a paddle card of a plug connector. The metal housing may have a tab engaging a wall of the insulative housing bounding the slot. The tab may be positioned such that, if a plug is improperly inserted into the receptacle, it presses against the tab. The tab may be configured to distribute force generated during an attempt to mate a misaligned plug away from thin wall portions of the insulative housing at an end of the slot. The tab may extend over a surface of the insulative housing beyond that thin wall portion and may be recessed into the housing.
Claims39
An electrical connector, comprising:
- an insulative member having a slot therein, a tapered portion at an opening of the slot, and a first recessed portion in the tapered portion;
- a plurality of contacts disposed along parallel side walls of the slot, wherein the contacts comprise mating portions that are elongated in a mating direction;
- and
- an electrically conductive member bounding at least three sides of the insulative member and comprising a first tab, wherein:
- the first tab comprises a tapered portion disposed in the first recessed portion of the insulative member at the opening of the slot;
- and
- the first tab is disposed over an interior surface of an end wall of the slot and projects away from the interior surface of the end wall so as to be further disposed over an interior surface of at least one of the parallel side walls of the slot.

An electrical connector, comprising:
- an insulative member having a slot therein and further having a first recessed portion;
- a plurality of contacts disposed along parallel side walls of the slot, wherein the contacts comprise mating portions that are elongated in a mating direction;
- and
- an electrically conductive member bounding at least three sides of the insulative member and comprising a first tab, wherein the first tab comprises:
- a tapered portion disposed in the first recessed portion of the insulative member at an opening of the slot;
- a straight portion disposed in the first recessed portion of the insulative member, extending into the slot in the mating direction, and extending beyond a distal tip of a mating portion of the plurality of contacts in a direction opposite the mating direction,
- wherein:
- the straight portion of the first tab and the first recessed portion of the insulative member are each disposed along a first parallel side wall of the parallel side walls;
- and
- the first recessed portion is shaped such that the straight portion, where disposed along the first parallel side wall, is no closer to a second parallel side wall of the parallel side walls than the first parallel side wall.
7 more elements
An electrical connector, comprising:
- an insulative member comprising first and second side walls and end walls bounding a slot the first and second side walls being parallel to one another with the first side wall separated from the second side wall in a first direction;
- a plurality of contacts disposed along the first side wall;
- and
- a metal shell comprising a body and a first tab extending from the body, wherein:
- the body surrounds the insulative member at least around the first side wall and the end walls, and the first tab extends over a first end wall of the end walls so as to bound a portion of the slot;
- and
- the first tab of the metal shell has a cross-section perpendicular to the mating direction that is U-shaped and the first tab extends in the first direction to a point adjacent the first side wall that is beyond the slot.
4 more elements
An electrical connector, comprising:
- an insulative housing comprising a slot;
- a plurality of contacts disposed along a first wall of the insulative housing adjacent the slot;
- and
- an electromagnetic shielding shell having a first portion at least partially surrounding the insulative housing and a second portion disposed along a second wall of the insulative housing adjacent the slot;
- wherein:
- the insulative housing comprises a tapered portion, with a tapered recessed portion in the tapered portion along the second wall,
- the second portion of the electromagnetic shielding shell is at least partially disposed in the tapered recessed portion, and
- the second portion of the electromagnetic shielding shell is tapered where disposed in the tapered recessed portion.
