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 The second arm is adverse to a direction along which the audio plug connector is withdrawn.
Claims16
An electrical contact of an audio jack connector, comprising:
- a main portion;
- a soldering portion bending from a lateral edge of the main portion;
- and
- an elastic portion extending curvedly from a distal end of the main portion to be located above the main portion, the elastic portion having a flexible beam, a first arm extending upwardly from the flexible beam and a second arm curvedly bending from the first arm;
- wherein a deformation of the elastic portion is compliant with a direction along which an audio plug connector is inserted and the deformation of the elastic portion is converse to a direction along which the audio plug connector is withdrawn.
An electrical contact for use with in an electrical connector, comprising:
- a 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;
- 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 and adapted to abut against the main portion when the elastic portion is deflected toward the main portion;
- wherein
- the front arc portion extends around 180 degrees to define rearward facing opening while the rear arc portion extends around 270 degrees to define a forwardly and downward facing opening.
An electrical contact for use with an electrical connector, comprising:
- a 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;
- 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 and adapted to abut against the main portion when the elastic portion is deflected toward the main portion;
- 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
- the front arc portion and the rear arc portion are spaced from each other via the flexible beam with a distance which is more than two times of a dimension of either the front arc portion and the rear arc portion in a front-to-back direction.
