Abstract
An electrical contact (100) of an audio jack connector includes a main portion (10), a soldering portion (30) bending from a lateral edge of the main portion, an elastic portion (20) extending curvedly from a distal end of the main portion to be located above the main portion. The elastic portion has a flexible beam (21), a first arm (22) extending upwardly from the flexible beam and a second arm (23) curvedly bending from the first arm. The first arm and is consistent with a direction along which an audio plug connector is inserted. The second arm is adverse to a direction along which the audio plug connector is withdrawn.
Claims13
An electrical contact for use with an electrical connector, comprising:
- a planar main portion adapted for retaining to a housing of the connector, the main portion having an upward stamped protrusion;
- a front arc portion unitarily extending from a front end of the main portion initially upwardly and further toward a rear end of the main body;
- and
- an elastic portion unitarily extending rearwardly from the front arc portion and spaced from the main body, said elastic portion including a flexible beam linked to the front arc portion, and a rear arc portion linked to the flexible beam and forming a contact section bulging upwardly beyond the flexible beam for deflection by an inserted plug to abut against the main portion;
- wherein
- the rear arc portion essentially extends initially rearwardly and upwardly and successively downwardly and further forwardly to define a loop like configuration;
- wherein
- the protrusion is positioned between the front arc portion and a free end of the rear arc portion along a front-to-back insertion direction, and the free end of the rear arc portion is connected with the protrusion when the plug is inserted to deflect the rear arc portion.

An electrical contact for use with in an electrical connector, comprising:
- a stationary planar main portion adapted for retaining to a housing of the connector;
- a front arc portion unitarily extending from a front end of the main portion initially upwardly and further toward a rear end of the main body in a front-to-back direction;
- and
- an elastic portion unitarily extending rearwardly from the front arc portion and spaced from the main body, said elastic portion including a flexible beam linked to the front arc portion, and a rear arc portion which is linked to the flexible beam and defines a contact section and essentially extends above the flexible beam for contact with a plug connector at a contacting point, and is adapted to abut against the main portion at an abutment point when the elastic portion is deflected toward the main portion by the plug connector;
- wherein
- the front arc portion defines rearward facing opening while the rear arc portion defines a forwardly and downward facing opening;
- wherein
- the contacting point and the abutting point are essentially aligned with each other in a vertical direction, which is perpendicular to the front-to-back direction, when the contact is in a relaxed manner, while the abutting point is moved forwardly to be forwardly offset from the contacting point when the elastic portion is deflected toward the main portion by the plug connector so as to form self-rotation of the rear arc portion in a tensioned manner.

- a front arc portion unitarily extending from a front end of the main portion initially upwardly and further toward a rear end of the main body;
- and
- an elastic portion unitarily extending rearwardly from the front arc portion and spaced from the main body, said elastic portion including a flexible beam linked to the front arc portion, and a rear arc portion which is linked to the flexible beam and defines a contact section and essentially extends above the flexible beam for contact with a plug connector and adapted to abut against the main portion when the elastic portion is deflected toward the main portion by the plug connector;
- wherein
- the rear arc portion essentially extends initially rearwardly and upwardly and successively downwardly and further forwardly to define wholly a loop like configuration regardless of whether a forward opening remains around a free end of the rear arc portion or not;
- wherein
- a stamped upward protrusion is formed on the main portion, and the rear arc portion contacts the main portion at a first point and contacts the protrusion at a second point around the tip section thereof when the flexible beam is deflected toward the main portion by the plug connector.
