Electrical connector with shielded power contacts

Claim 2

A connector assembly comprising a plug connector holding a plurality of signal contacts, each extending in a mating direction, and aligned in a row extending transversely of the mating direction and longitudinally between opposite ends of a plug housing; and a receptacle connector holding a plurality of signal contacts, each extending in a mating direction, and aligned in a row extending transversely of the mating direction and longitudinally between opposite ends of a receptacle housing; said signal plug contacts connecting with respective, corresponding signal receptacle contacts as said plug connector is received in and mated with said receptacle connector; said connector assembly further comprising: two poles of power plug contacts disposed within said plug housing at respective opposite ends of said row of signal plug contacts in alignment therewith and extending in the mating direction; two poles of power receptacle contacts disposed within said receptacle housing at respective opposite ends of with said row of signal receptacle contacts in alignment therewith and extending in the mating direction, said power receptacle contacts being connected to said power plug contacts when said plug connector is received in and mated with said receptacle connector; a conductive plug-connector securing metal part disposed at each of said opposite ends of said plug housing; and a conductive receptacle-connector securing metal part disposed at each of said opposite ends of said receptacle housing, said receptacle-connector securing metal part being adapted to connect with said plug-connector securing, metal part when said plug connector and said receptacle connector mate together, said plug-connector securing metal part and said receptacle-connector securing metal part being electrically insulated from said power plug contacts and said power receptacle contacts and disposed so as to respectively cover at least parts of outer peripheries of said power plug contacts and power receptacle contacts.

Claim 3

A connector assembly according to claim 1, wherein said power plug contacts and power receptacle contacts are disposed at positions asymmetrical to each other direction of a respective row with respect to said signal plug contacts and signal receptacle contacts, respectively.

Claim 4

A connector assembly according to claim 1, wherein heights of said securing parts, power contacts, and signal contacts in the mating direction thereof are set such that, when said plug connector is received in and mated with said receptacle connector, said plug-connector securing metal part and receptacle-connector securing metal part are initially connected together, then said power plug contacts and power receptacle contacts are connected together, and thereafter said signal plug contacts and signal receptacle contacts are connected together.

Claim 5

A connector assembly comprising a plug connector holding a plurality of signal contacts, each extending in a mating direction, and aligned in a row extending transversely of the mating direction and longitudinally between opposite ends of a plug housing; and a receptacle connector holding a plurality of signal contacts, each extending in a mating direction, and aligned in a row extending transversely of the mating direction and longitudinally between opposite ends of a receptacle housing; said signal plug contacts connecting with respective, corresponding signal receptacle contacts as said plug connector is received in and mated with said receptacle connector; said connector assembly further comprising: two poles of power plug contacts disposed within said plug housing at respective opposite ends of said row of signal plug contacts in alignment therewith and extending in the mating direction; two poles of power receptacle contacts disposed within said receptacle housing at respective opposite ends of with said row of signal receptacle contacts in alignment therewith and extending in the mating direction, said power receptacle contacts being connected to said power plug contacts when said plug connector is received in and mated with said receptacle connector; a conductive plug-connector securing metal part disposed at each of said opposite ends of said plug housing; and a conductive receptacle-connector securing metal part disposed at each of said opposite ends of said receptacle housing, said receptacle-connector securing metal part being adapted to connect with said plug-connector securing, metal part when said plug connector and said receptacle connector mate together, wherein said receptacle-connector securing metal parts and said plug-connector securing metal parts include respective shielding portions each having a pair of arms extending in spaced apart relation from a bight to form a U-shape with an axis extending in the mating direction and a mouth opening toward the row so as to at least partly surround respective power plug contacts and power receptacle contacts, said receptacle-connector securing metal parts being adapted to connect with said plug-connector securing metal parts by mating of respective said shielding portions.

Claim 6

A connector assembly comprising a plug connector holding a plurality of signal contacts, each extending in a mating direction, and aligned in a row extending transversely of the mating direction and longitudinally between opposite ends of a plug housing; and a receptacle connector holding a plurality of signal contacts, each extending in a mating direction, and aligned in a row extending transversely of the mating direction and longitudinally between opposite ends of a receptacle housing; said signal plug contacts connecting with respective, corresponding signal receptacle contacts as said plug connector is received in and mated with said receptacle connector; said connector assembly further comprising: two poles of power plug contacts disposed within said plug housing at respective opposite ends of said row of signal plug contacts in alignment therewith and extending in the mating direction; two poles of power receptacle contacts disposed within said receptacle housing at respective opposite ends of with said row of signal receptacle contacts in alignment therewith and extending in the mating direction, said power receptacle contacts being connected to said power plug contacts when said plug connector is received in and mated with said receptacle connector; a conductive plug-connector securing metal part disposed at each of said opposite ends of said plug housing; and a conductive receptacle-connector securing metal part disposed at each of said opposite ends of said receptacle housing, said receptacle-connector securing metal part being adapted to connect with said plug-connector securing, metal part when said plug connector and said receptacle connector mate together, wherein said receptacle-connector securing metal parts and said plug-connector securing metal parts include respective shielding portions each having a pair of arms extending in spaced apart relation from a bight to form a U-shape with an axis extending in the mating direction and a mouth opening toward the row so as to at least partly surround respective power plug contacts and power receptacle contacts, said receptacle-connector securing metal parts being adapted to connect with said plug-connector securing metal parts by mating of respective said shielding portions.
