STRUCTURAL ASSOCIATIONS OF A PLURALITY OF MUTUALLY-INSULATED ELECTRICAL CONNECTING ELEMENTS; COUPLING DEVICES; CURRENT COLLECTORS ## Abstract An electrical connector includes: an insulative housing; a single row of contacts secured to the insulative housing and each having a soldering tail; and a shielding shell enclosing the insulative housing and having an annular part and a pair of soldering portions; wherein the shielding shell annular part is seamless; and the soldering tails of the single row of contacts are arranged alternately in two rows within an outer profile of the shielding shell annular part. ## Claims ### Claim 1 An electrical connector assembly comprising: a plug connector and a receptacle connector configured to be adapted for mating with each other, said plug connector including: an insulative plug housing enclosed in a metallic plug shielding shell and including a horizontal base with a vertical mating tongue surrounded by a vertical peripheral wall with a vertical annular groove therebetween, said peripheral wall being fully circumferentially enclosed by the plug shielding shell; one row of plug contacts secured to the plug housing along a longitudinal direction, each of said plug contacts including a contacting portion positioned upon the mating tongue, a soldering portion exposed under the base, and a securing portion located between the contacting portion and the soldering portion and retained to the housing; said receptacle connector including: an insulative receptacle housing enclosed in a metallic receptacle shielding shell and including a horizontal base with a vertical lip having a groove therein; one row of receptacle contacts secured to the receptacle housing along the longitudinal direction, each of said receptacle contacts including a contacting section disposed in the groove, a soldering section located under the base, and a securing section located between the contacting section and the soldering section and retained to the housing; wherein said plug contacts are arranged with opposite orientations alternately and said receptacle contacts are arranged with opposite orientations alternately; wherein in each coupled/paired plug contact and receptacle contact, the soldering portion of the plug contact and the soldering section of the receptacle contact are located by opposite sides of the mating tongue, viewed along said longitudinal direction. ### Claim 2 (depends on 1) The electrical connector assembly as claimed in claim 1, wherein the plug shielding shell includes an annular portion intimately enclosing the peripheral wall, and a horizontal seat with a plug chamfered structure, and the receptacle shielding shell includes an annular section distantly enclosing the lip, and a horizontal plate with a receptacle chamfered structure which is aligned with the plug chamfered structure during mating. ### Claim 3 (depends on 2) The electrical connector assembly as claimed in claim 2, wherein a mating space is formed between the lip and the receptacle shielding shell for receiving the peripheral wall and the plug shielding shell therein. ### Claim 4 (depends on 1) The electrical connector assembly as claimed in claim 1, wherein the plug housing forms a plurality of windows in which the corresponding soldering portions are exposed, respectively. ### Claim 5 (depends on 1) The electrical connector assembly as claimed in claim 1, wherein the receptacle housing forms a pair of windows to expose the corresponding soldering sections therein. ### Claim 6 (depends on 1) The electrical connector assembly as claimed in claim 1, wherein both said plug shielding shell and said receptacle shielding shell are fully seamlessly circumferential. ### Claim 7 (depends on 1) The electrical connector assembly as claimed in claim 1, wherein in the plug connector, the plug housing is integrally formed with the plug contacts while the plug shielding shell is attached to the plug housing separately; in the receptacle connector, the receptacle housing is integrally formed with the receptacle shielding shell while the receptacle contacts are attached to the receptacle housing separately. ### Claim 8 (depends on 1) The electrical connector assembly as claimed in claim 1, wherein the peripheral wall forms a plurality of peripheral recesses, and the plug shielding shell forms a plurality of inward dimples respectively engaged within the corresponding recesses, and the receptacle shielding shell includes a plurality of protrusions engaged with within the corresponding dimples, respectively.
