Abstract

An electrical connector includes a base with a number of contacts, a cover pivotally mounted to the base, a pair of supporting components for mating with the cover, and a reinforce piece fixed to the cover. The reinforce piece is fixed to the cover and includes a pair of opposite engaging projections extending into the front opening The cover and the pair of supporting components are mateable with each other in condition that one of the cover and the pair of supporting components pivots clockwise while a remaining one of the cover and the pair of supporting components pivots anti-clockwise. The cover and the supporting components are pivotal between an opening location and a closed location for receiving a plug connector.

Claims

1. An electrical connector comprising:

a base comprising a plug-receiving cavity and a slant guiding surface for obliquely guiding insertion of a plug connector into the plug-receiving cavity;

a plurality of contacts retained in the base, each contact comprising a resilient contacting portion protruding into the plug-receiving cavity;

a cover pivotally mounted at a rear of the base, the cover being pivotal between an opened status and a closed status with respect to the base along a first pivot member, the cover defining a front opening opposite to the first pivot member;

a pair of supporting components for mating with the cover, each supporting component being pivotal between an opened status and a closed status with respect to the base along a second pivot member; and

a reinforce piece fixed to the cover and comprising a pair of opposite engaging projections both extending into the front opening;

wherein

the cover and the pair of supporting components are mateable with each other in condition that one of the cover and the pair of supporting components pivots clockwise while a remaining one of the cover and the pair of supporting components pivots anticlockwise; and

wherein

(i) the cover and the supporting components are pivotal to an opening location where the plug connector can be inserted into the plug-receiving cavity; and

(ii) the cover and the supporting components are pivotal to a closed location where the plug connector is restricted by the engaging projections so as to be prevented from withdrawing from the plug-receiving cavity.

2. The electrical connector as claimed in claim 1, wherein the cover is insulative, and the reinforce piece is metallic and embedded in the cover for enhancing rigidity of the cover.

3. The electrical connector as claimed in claim 2, wherein the reinforce piece defines a plurality of holes into which a material of the cover flows during an injection-molding process.

4. The electrical connector as claimed in claim 1, wherein the first pivot member comprises a pair of first shafts formed on lateral sides of the cover and a pair of cutouts formed on the base, the pair of first shafts being pivotal in the cutouts so that the cover can be pivotal between the opened status and the closed status.

5. The electrical connector as claimed in claim 4, wherein the base comprises a pair of extensions with the pair of cutouts formed thereon, respectively, each cutout being opened at its top side, each contact comprising a tail portion residing in a space formed between the pair of extensions, the space being separated from the plug-receiving cavity along a front-to-back direction.

6. The electrical connector as claimed in claim 4, wherein the second pivotal member comprises a pair of round holes formed on the pair of supporting components, respectively, and a pair of second shafts formed in the base, the pair of second shafts being pivotal in the round holes so that the supporting components can be pivotal between the opened status and the closed status.

7. The electrical connector as claimed in claim 6, wherein the base defines a pair of side walls at opposite sides of the plug-receiving cavity, each side wall defining a slit for receiving corresponding supporting component, the second shafts being exposed to the slits.

8. The electrical connector as claimed in claim 7, wherein each supporting component defines a longitudinal slot opposite to corresponding round hole, the cover comprising a pair of protrusions on the lateral sides thereof, the protrusions being positioned between the first shafts and the second shafts along a front-to-back direction, each protrusion being slidable in corresponding longitudinal slot either when the cover pivots from the opened status to the closed status or when the cover pivots from the closed status to the opened status.

9. The electrical connector as claimed in claim 8, wherein a center line of each first shaft is lower than that of each protrusion for not only reducing a height of the electrical connector but also providing robust engaging force between the base and the cover.

10. An electrical connector for being mounted in an electronic device, comprising:

a base defining a plug-receiving cavity;

a plurality of contacts with resilient contacting portions protruding into the plug-receiving cavity for mating with a plug connector;

a cover pivotally mounted at a rear of the base, the cover being pivotal with respect to the base along a first pivot member; and

a pair of supporting components for mating with the cover, each supporting component being pivotal with respect to the base along a second pivot member;

wherein

each supporting component comprises a slot and the cover comprises a pair of protrusions slidable in the slots for controlling an opening range of the cover; and

wherein

the cover and the pair of supporting components are mateable with each other in condition that one of the cover and the pair of supporting components pivots clockwise while a remaining one of the cover and the pair of supporting components pivots anticlockwise; and

wherein

the cover and the supporting components are pivotal to an opening location where the plug connector can be inserted into the plug-receiving cavity, and the cover and the supporting components can be pivotal to a closed location where the plug connector is maintained in the plug-receiving cavity; and

wherein

the protrusions are located between the first pivotal member and the second pivot member along a front-to-back direction while a center line of the first pivot member is lower than that of the protrusions.

11. The electrical connector as claimed in claim 10, wherein the cover is made of a kind of metallic material through press casting, the cover comprising a front opening opposite to the first pivot member and a pair of engaging projections extending into the front opening to restrict the plug connector when the plug connector is received in the plug-receiving cavity.

12. The electrical connector as claimed in claim 10, further comprising an insulative layer covering the cover, a color of the insulative layer being the same as or similar to that of the electronic device.

13. The electrical connector as claimed in claim 10, wherein the first pivot member comprises a pair of first shafts formed on lateral sides of the cover, a pair of mounting holes formed in the base and an axis extending through the first shafts and the mounting holes.

14. The electrical connector as claimed in claim 13, wherein each first shaft defines a first through hole in alignment with the mounting holes along a transverse direction, the axis being separated made with respect to the cover while is inserted through the first through holes and the mounting holes.

15. The electrical connector as claimed in claim 14, wherein the base comprises a pair of backward extensions each of which comprises an inner wall, an outer wall and a space between the inner wall and the outer wall to receive the first shafts.

16. The electrical connector as claimed in claim 15, wherein each mounting hole comprises a first cutout upwardly opened at a top side of the inner wall and a second cutout downwardly opened at a bottom side of the outer wall.

17. The electrical connector as claimed in claim 16, further comprising a pair of blocking pieces outside of the outer walls, the pair of blocking pieces being attached to the axis from opposite ends for fixing the axis.
