Abstract

The electrical connector in accordance with the present invention comprises: contact pieces having contacts and terminal portions, a connector body which houses and holds the contact pieces; a casing shield frame unit; and arms each having one end secured to the lateral wall portions of the shield frame unit and the other end, or free end, at which contacts are formed. The contacts which come in contact with a counter electrical connector, may be displaced inside of the shield frame unit, thus minimizing the height of the electrical connector as mounted on a printed circuit board.

Claims

1. An electrical connector comprising:

contact pieces provided at the tips thereof with contacts and having terminal portions;

a connector body having (i) a main body which houses parts of said terminal portions of said contact pieces and (ii) a contact piece holding member projecting from said main body for holding said tips of said contact pieces at which said contacts are formed;

a casing shield frame unit surrounding the entire periphery of said contact piece holding member;

arms having one end secured to lateral wall portions of said shield frame unit which are opposite to lateral surfaces of said contact piece holding member, said one end being electrically connected to said shield frame unit; and

contacts formed at the free ends of said arms and adapted to come in contact with or separated from the outside surfaces of lateral walls of the shield frame unit of a counter electrical connector which are inserted in or removed from the spaces formed between said casing shield frame unit and said contact piece holding member of said connector body.

2. An electrical connector according to claim 1, wherein the shield frame unit includes a casing first frame and a second frame having the arms.

3. An electrical connector according to claim 2, wherein the first frame is fitted to the outside of the second frame into which the main body is fitted, so that said first and second frames are electrically connected to each other.

4. An electrical connector according to claim 3, wherein the main body has a plurality of grooves which are opened in the back side and underside of the main body, and the terminal portions of the contact pieces project downwardly from said main body through said grooves.

5. An electrical connector according to claim 3, wherein the main body has a plurality of grooves which are opened in the back side and underside of the main body, and the terminal portions of the contact pieces are extended rearwardly of said main body substantially at the same level as that of the bottom surface of said main body.
