Abstract
An audio jack connector (100) includes an insulative housing (2) defining a receiving space (20), a number of signal contacts (31, 32) retained in the insulative housing, and a pair of griping contacts (33) retained in the insulative housing too. The signal contacts have a number of first contacting portions (311, 321) extending into the receiving space from a left-and-right direction perpendicular to a mating direction along which an audio plug connector is inserted into the receiving space. The gripping contacts have at least three second contacting portions (332, 333/3331) extending into the receiving space from a vertical direction perpendicular to both the left-and-right direction and the mating direction.

An audio jack connector comprising:
- an insulative housing defining a receiving space;
- a plurality of signal contacts retained in the insulative housing and having a plurality of first contacting portions extending into the receiving space from a left- and-right direction perpendicular to a mating direction along which an audio plug connector is inserted into the receiving space;
- and a pair of griping contacts retained in the insulative housing, each griping contact having a base portion, an elastic portion extending from the base portion to be located above the receiving space, and a flat portion bending from the base portion to be located below the receiving space, at least one of the flat portions having a protrusion protruding toward the receiving space, the two elastic portions and the protrusion extending from opposite sides into the receiving space along a vertical direction perpendicular to both the left-and-right direction and the mating direction, wherein the base portions, the elastic portions, and the flat portions of the gripping contacts are disposed peripherally around the receiving space, wherein the base portion has a stamped, cantilevered, flexible tongue portion and a rigid tab oppositely extending with respect to the tongue portion, and wherein the rigid tab is retained in the insulative housing, wherein the gripping portion has a board lock extending perpendicular to the rigid tab and the flexible tongue portion, wherein the elastic portions of the griping contacts are angled as viewed from a top side of the receiving space.
An audio jack connector for use with an audio plug, comprising:
- an insulative housing defining opposite front and rear faces in a front-to-back direction;
- a plug receiving space formed in the housing with at least an opening in the front face to forwardly communicate with an exterior in said front-to-back direction, said plug receiving space essentially being of a columnar configuration with an imaginary center axis extending along said front-to-back direction;
- a plurality of signal contacts located by at least one side of the receiving space in a transverse direction perpendicular to said front-to-back direction, each of said signal contacts including a contacting section extending into the receiving space for contacting the audio plug in said transverse direction;
- and a combo contact located behind said signal contacts and defining a pair of elastic contacting portions and a protrusion commonly forming, viewed in said front-to-back direction, a three-point contact during mating with the audio plug;
- wherein said three point contact is configured with an isosceles triangle with thereof an imaginary vertical bisector extending through the imaginary center axis, wherein said combo contact includes a pair of griping contacts essentially arranged by two sides of the receiving space, and said pair of elastic contacting portions are respectively formed on said pair of grip contacts, respectively, wherein said pair of griping contacts are asymmetric with each other, and only one of said griping contacts defines said protrusion, wherein said pair of griping contacts are discrete from each other, and each of said pair of griping contacts is configured with a U-shape view in said front-to-back direction.
