Abstract

An connector assembly includes a male connector ( 100 ) having a male housing ( 10 ) and a plurality of male contacts ( 12 ); and a female connector ( 200 ) for mating with said male connector including a female housing ( 20 ) and a plurality of female contacts ( 21 ) retained in said female housing. Each female contact defines a pair of mating plates ( 211 ) spaced away from each other for said male contact locating therebetween. Each pair of said mating plates ( 211 ) have a pair of spring leaves ( 22 ) connecting therewith and defining a plurality of spring fingers ( 221 ) resiliently clamping the corresponding male contact ( 12 ) therebetween.

First claim

1 . A connector assembly comprising:
a male connector including a male housing and a plurality of male contacts for connecting to electric cables; a female connector for mating with said male connector including a female housing and a plurality of female contacts retained in said female housing, each female contact defining a pair of mating plates spaced away from each other to sandwich said male contact therebetween; and a pair of spring leaves each defining a plurality of spring fingers and located between the male contact and the corresponding mating plate of the female contact; wherein said spring leaves are assembled to the corresponding mating plates; said female connector further comprises a pair of protection boards retained in said female housing and attaching to each pair of said mating plates; each protection board has a groove receiving the corresponding mating plate and spring leaf, and a set of posts being retained into a set of holes formed at said mating plate.

2 . The connector assembly as claimed in claim 1 , wherein each pair of said spring leaves extend along said mating plates in a mating direction of said connector assembly, each spring finger defines a pair of convex portions disposed in the mating direction and resisted between the respective male contact and mating plate.

3 . The connector assembly as claimed in claim 2 , wherein said spring fingers of each spring leaf are spaced from each other at intervals in a traverse direction perpendicular to said mating direction and connected by two bars at two opposite ends of said spring fingers in said mating direction.

4 . The connector assembly as claimed in claim 1 , wherein each spring leaf includes a hook clasping a free end of the corresponding mating plate, and a pair of legs extending at two lateral sides of said spring fingers and defining two latches locking onto two lateral sides of said corresponding mating plate.

5 . (canceled)

6 . The connector assembly as claimed in claim 1 , wherein said female connector further comprises a shielding shell surrounding the corresponding pair of protection boards, said shielding shell defines a set of feet retained in said female housing and a cutout for said male connector passing through.

7 . The connector assembly as claimed in claim 6 , wherein said male connector further comprises a set of retainers retaining said male contacts, and metal shells enclosing said retainers respectively; each retainer defines a cavity receiving the respective male contact and mating plates, and a channel accommodating the shielding shell of the female connector; each metal shell defines at least one clip protruding inwardly and resisting the respective shielding shell.

8 . The connector assembly as claimed in claim 1 , wherein said male connector further comprises a locking lever mounted onto said male housing and pivotably around a pair of shafts formed at two lateral sides of said male housing, said locking lever has a pair of arcuate holes formed at two lateral sides thereof for engaging a pair of raised portions formed at said female housing so as to actuating said male connector moving toward or away from said female connector.

9 . A female connector comprising:
a female housing defining a pair of chambers; a pair of female contacts retained in said female housing and accommodated in said pair of chambers respectively, each female contact having a pair of mating plates protruding into the corresponding chamber and spaced from each other in a face-to-face manner; a pair of planar spring leaves coupled to each pair of said mating plates, each one of said pair of spring leaves comprising a plurality of spring fingers relaying on inner sides of the corresponding mating plates and protruding toward another of said pair of spring leaves; and two pairs of protection boards accommodated in said chambers respectively to firm said spring leaves and corresponding female contacts together.

10 . (canceled)

11 . The female connector as claimed in claim 9 , wherein each spring leaf includes a hook clasping a free end of the corresponding mating plate, each protection board has a groove hosting the corresponding mating plate and spring leaf.

12 . The female connector as claimed in claim 11 , wherein each protection board has a set of posts being retained into a set of holes formed at said mating plate; each spring leaf has a pair of legs extending at two lateral sides of said spring fingers and defining two latches locking onto two lateral sides of said corresponding mating plate, each protection board has a pair of gaps for receiving said latches.

13 . The female connector as claimed in claim 9 , wherein said female connector further comprises a pair of shielding shells received in the respective chambers and surrounding the protection boards respectively, said shielding shell defines a set of feet retained in said female housing.

14 . An electrical connector assembly comprising:
a receptacle connector including: a first insulative housing assembly defining a mating cavity upwardly exposed to an exterior in a vertical direction; a pair of contacting plates disposed in the mating cavity and facing to each other in a first transverse direction perpendicular to said vertical direction; a first metallic shielding shell disposed in the mating cavity and enclosing said pair of contacting plates; a plug connector including: a second insulative housing assembly defining a receiving cavity downwardly exposed to an exterior; a single contacting blade disposed in the receiving cavity; a second metallic shielding shell disposed in the receiving cavity and enclosing said single contacting blade; a cable connected to the single contacting blade extending through said second metallic shielding shell and out of the second housing along a second transverse direction perpendicular to both said vertical direction and said first transverse direction; wherein the single contacting blade extends in a plane defined by both said vertical direction and said second transverse direction; wherein during mating the plug connector with the receptacle connector along the vertical direction, the first metallic shielding shell and the pair of contacting plates are commonly received within the receiving cavity, the signal contacting blade is snugly sandwiched between the pair of contacting plates in the first transverse direction, and the first metallic shielding shell is enclosed within and mechanically and electrically connected to said second metallic shielding shell.

15 . The electrical connector assembly as claimed in claim 14 , wherein the second housing assembly forms a channel to receive said first metallic shielding shell during mating.

16 . The electrical connector assembly as claimed in claim 14 , wherein the second metallic shielding shell forms a plurality of inward extending spring arms to mechanically and electrically contact the first metallic shielding shell during mating.

17 . The electrical connector assembly as claimed in claim 14 , wherein said second insulative housing assembly includes an insulative main body, and an insulative retainer enclosed and retained within the second metallic shielding shell, and the pair of contacting plates and the first metallic shielding shell are commonly received within the retainer during mating, and the main body defines a downward facing space to allow the assembled second metallic shielding shell and insulative retainer to be upwardly assembled into the space along the vertical direction while said main body further defines a passage to
