Electrical connector having a middle metal plate with two pairs of fingers contacting an upper and lower ground contacts
An electrical connector includes: an insulative housing having a tongue; an upper and lower rows of contacts secured to the insulative housing and exposed to two opposite faces of the tongue, the upper row of contacts including an upper ground contact and the lower row of contacts including a lower ground contact; and a metal plate disposed between the upper row of contacts and the lower row of contacts, wherein the metal plate has a pair of upper fingers contacting the upper ground contact and a pair of lower fingers contacting the lower ground contact.
1. An electrical connector comprising:
an insulative upper housing part with a plurality of upper contacts embedded therein via an insert-molding process;
a lower insulative housing part with a plurality of lower contacts embedded therein via another insert-molding process;
a metal plate sandwiched between the upper housing part and the lower housing part in a vertical direction with a plurality of grounding fingers respectively contacting corresponding ground contacts of the plurality of upper contacts and the plurality of lower contacts in the vertical direction; and
a metallic shell circumferentially enclosing the upper housing part and the lower housing part; wherein
the upper housing part forms an upper aperture extending therethrough in the vertical direction to circumferentially expose a portion of each corresponding upper contact while being blocked by the shell and the metal plate at two ends thereof in the vertical direction; and
the lower housing part forms a lower aperture extending therethrough in the vertical direction to circumferentially expose a portion of each corresponding lower contact while being blocked by the shell and the metal plate at two ends thereof in the vertical direction.
2. The electrical connector as claimed in claim 1 , wherein the upper aperture and the lower aperture are aligned with each other in the vertical direction.
3. The electrical connector as claimed in claim 1 , wherein the upper housing part and the lower housing part form respectively recesses to snugly receive the metal plate in at least the vertical direction.
4. The electrical connector as claimed in claim 3 , wherein said recesses further snugly receive the metal plate horizontally circumferentially.
5. An electrical connector comprising:
a plurality of upper contacts integrally formed within an insulative upper housing part via an insert-molding process and including an upper ground contact, each of said upper contacts including a front contacting portion and a rear soldering portion along a front-to-back direction;
a plurality of lower contacts integrally formed within an insulative lower housing part via another insert-molding process and including a lower ground contact, each of said lower contacts including a front contacting portion and a rear soldering portion along the front-to-back direction; and
a metal plate disposed between the insulative upper housing part and the insulative lower housing part in a vertical direction perpendicular to said front-to-back direction; wherein
the metal plate has a pair of upper fingers spaced from each other along the front-to-back direction and respectively contacting the front contacting portion and the rear soldering portion of the upper ground contact, and a pair of lower fingers spaced from each other along the front-to-back direction and respectively contacting the front contacting portion and the rear soldering portion of the lower ground contact.
6. An electrical connector comprising:
a plurality of upper contacts integrally formed within an insulative upper housing part via an insert-molding process and including an upper ground contact, each of said upper contacts including a front contacting portion and a rear soldering portion along a front-to-back direction;
a plurality of lower contacts integrally formed within an insulative lower housing part via another insert-molding process and including a lower ground contact, each of said lower contacts including a front contacting portion and a rear soldering portion along the front-to-back direction; and
a metal plate disposed between the insulative upper housing part and the insulative lower housing part in a vertical direction perpendicular to said front-to-back direction; wherein
the metal plate has a pair of upper fingers spaced from each other along the front-to-back direction and respectively contacting two different positions of the upper ground contact along the front-to-back direction, and a pair of lower fingers spaced from each other along the front-to-back direction and respectively contacting two different positions of the lower ground contact along the front-to-back direction; wherein
the insulative upper housing part includes a pair of apertures dimensioned to properly comply with the upper spring fingers in the front-to-back direction to protectively allow the pair of upper fingers to extend therethrough, respectively, and the insulative lower housing part forms a pair of apertures dimensioned to properly comply with the lower spring fingers in the front-to-back direction to protectively allow the pair of lower fingers to extend therethrough, respectively.
7. The electrical connector as claimed in claim 6 , wherein the pair of upper fingers are located at opposite front and rear edges of the metal plate, and the pair of lower fingers are located at said opposite front and rear edges of the metal plate.
