ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to an electric connector, more particularly to such an electric connector, which is designed for connection to a bus line to receive a matching electric connector for signal transmission.
FIG. 1
shows an electric connector according to the prior art. This structure of electric connector comprises an electrically insulative housing
10
, two longitudinal rows of signal terminals
11
and a longitudinal row of grounding terminals
12
respectively mounted in the housing
10
. The forked tips
13
and
14
of the terminals
11
and
12
protrude over the topside wall of the housing
10
. As illustrated in
FIGS. 2 and 3
, the grounding terminals
12
are formed integral with one another, and elongated projecting portions
15
are provided at the metal bar of grounding terminals
12
for contacting particular terminals
11
. When grounding terminals
16
of the matching electric connector are respectively inserted into the housing
10
, they are respectively forced into contact with the curved bottom contact portion
17
of each of the terminals
11
being connected to the grounding terminals
12
. Because the elongated projecting portions
15
at the grounding terminals
12
, the curved bottom contact portions
17
of the respective terminals
11
and the grounding terminals
16
of the matching electric connector are disposed at different elevations, the grounding contact is unstable, and the unstable grounding contact tends to affect the transmission of signal.
SUMMARY OF THE INVENTION
The present invention has been accomplished to provide an electric connector, which eliminates the aforesaid problem. According to the present invention, the electric connector comprises a housing having two longitudinal rows of terminal slots and a longitudinal insertion slot between the longitudinal rows of terminal slots, signal terminals and grounding terminals respectively mounted in the terminal slots, and a metal grounding plate inserted into the longitudinal insertion slot, the metal grounding plate having springy protruding portions inserted into grounding terminal slots for holding down grounding terminals of the matched electric connector with respective spring strips at the grounding terminals. Because the springy protruding portions of the metal grounding plate and the spring strips of the grounding terminals are disposed at same elevation, the grounding terminals of the matching electric connector can be positively held down by the grounding terminals and the metal grounding plate.
