Abstract

A HDMI connector is disclosed to include an insulative casing holding first terminals and second terminals at two different elevations, an insulative locating board set in between the first terminals and second terminals, top and bottom cove boards respectively covered on the top and bottom sides of the locating boards to hold down lead wires of a cable in respective forked, sharp-edged endpieces of the first terminals and second terminals at the top and bottom sides of the insulative locating board to make a respective electric contact, a cap fastened to the cable to keep the lead wires from sight, a metal shield covered on the casing and the cover boards and the cap for EMI protection, and a plastic housing directly molded on the metal shield.

Claims

1. A Hi-definition Multimedia Interface (HDMI) connector comprising:

an electrically insulative casing, said casing comprising two protruding blocks respectively vertically extended from a rear sidewall thereof on the middle in reversed directions;

a set of terminals, said terminals including a plurality of first terminals horizontally arranged in said casing at an upper side and a plurality of second terminals horizontally arranged in said casing at a lower side below said first terminals, said first terminals being axially alternatively extended out of the rear sidewall of said casing at two different distances, said second terminals being axially alternatively extended out of the rear sidewall of said casing at two different distances, said first terminals each having an upwardly extended, forked, sharp-edged endpiece suspending outside the casing, said second terminals each having a downwardly extended, forked, sharp-edged endpiece suspending outside said casing;

an electrically insulative locating board fastened to said casing and set between said first terminals and said second terminals, said locating board comprising a plurality of first locating pins and second locating pins respectively perpendicularly extended from top and bottom sides thereof on the middle, and a plurality of locating holes in four corners thereof;

a top cover board and a bottom cover board respectively fastened to the top and bottom sides of said locating board, said top cover board and said bottom cover board each having a plurality of mounting holes respectively coupled to the first locating pins and second locating pins of said locating board, and a plurality of retainers respectively fastened to the locating holes of said locating board, said top cover board having a plurality of parallel terminal grooves formed in a bottom side thereof for accommodating the upwardly extended, forked, sharp-edged endpieces of said first terminals, said bottom cover board having a plurality of parallel terminal grooves formed in a top side thereof for accommodating the downwardly extended, forked, sharp-edged endpieces of said second terminals;

a cable, said cable having a plurality of lead wires arranged into two groups respectively inserted into the terminal grooves of said top cover board and the terminal grooves of said bottom cover board and respectively held down in the upwardly extended, forked, sharp-edged endpieces of said first terminals and the downwardly extended, forked, sharp-edged endpieces of said second terminals by said top cover board and said bottom cover board and respectively kept in electric contact with said first terminals and said second terminals;

a protective cap mounted on said cable and closely attached to said top cover board and said bottom cover board and said locating board at a rear side to protect the lead wires of said cable and to keep the lead wires of said cable from sight;

a metal shield covered on said top cover board and said bottom cover board and said protective cap for EMI (Electromagnetic interference) protection, said metal shield having a part covered on the periphery of said casing and forming with said casing a connection interface; and

a plastic housing molded on said metal shield said cable and to a portion of said connection interface.

2. The HDMI connector as claimed in claim 1, wherein said casing has a plurality of mounting holes bilaterally formed in the rear sidewall;

said locating board has a plurality of plug rods extended from a front side thereof and respectively press-fitted into the mounting holes of said casing.

3. The HDMI connector as claimed in claim 1, wherein said metal shield comprises a bottom shell covered on said casing and said bottom cover board at a bottom side, and a top cover shell covered on said casing and said bottom cover board at a top side, said bottom shell comprising a substantially U-shaped shell body covered on said bottom cover board, a front socket portion extended from a front side of said shell body and coupled to said casing and forming with said casing said connection interface, and a rear clamping portion extended from a rear side of said shell body and clamped on the periphery of said cable, said shell body having a plurality of protruding hooked portions symmetrically disposed at two opposite lateral sides thereof, said top cover shell having a plurality of retaining holes symmetrically disposed at two opposite lateral sides thereof and respectively fastened to the protruding hooked portions of said shell body and a rear extension strip secured to the periphery of said cable by said clamping portion of said shell body.
