Abstract

An electrical plug connector has an insulative housing, two terminal sets, a shielding-grounding plate and a shell. The terminal sets are mounted in the insulative housing and each terminal set has multiple conductive terminals. The shielding-grounding plate is mounted in a rear end of the insulative housing and has a shielding body mounted in the rear end of the insulative housing and located between the terminal sets and two resilient hooking arms formed on and protruding forward respectively from two opposite sides of the shielding body and extending in the insulative housing. The shielding-grounding plate is located above the conductive terminals of the two terminal sets and shields the terminal sets such that each terminal set would not interfere with the other terminal set with cross talk when implementing signal transmission.

First claim

What is claimed is:

a mounting section mounted on the top board or the bottom board of the insulative housing;
an electrical contacting section formed on and protruding forward from the mounting section and extending in the insertion space; and
a soldering section formed on and protruding backward from the mounting section, wherein the electrical contacting sections of one of the terminal sets are arranged in an upper row, and the electrical contacting sections of the other terminal set are arranged in a lower row aligned with the upper row, wherein the soldering sections of one terminal set are arranged in an upper row, and the soldering sections of the other terminal set are arranged in a lower row aligned with the upper row;
a shielding-grounding plate mounted in a rear end of the insulative housing and having
a shielding body mounted in the rear end of the insulative housing and located between the terminal sets; and
two resilient hooking arms formed on and protruding forward respectively from two opposite sides of the shielding body and extending in the insertion space of the insulative housing; and
a shell having a cavity defined in the shell and accommodating the insulative housing.

2 . The electrical plug connector as claimed in claim 1 , wherein

3 . The electrical plug connector as claimed in claim 2 , wherein
the insulative housing has an assembling slot defined in the rear end of the insulative housing; the shielding-grounding plate has an extension shielding sheet formed on and protruding forward from the shielding body, mounted in the assembling slot of the insulative housing, and located between the mounting sections of the conductive terminals of the two terminal sets.

4 . The electrical plug connector as claimed in claim 3 , wherein
the assembling slot has two opposite hooking notches defined respectively in two opposite inner walls of the assembling slots; the shielding-grounding plate has two fastening elements formed and protruding forward from the shielding body and engaged respectively with the hooking notches.

5 . The electrical plug connector as claimed in claim 4 , wherein each fastening element of the shielding-grounding plate is located between the extension shielding sheet and one of the resilient hooking arms.

6 . The electrical plug connector as claimed in claim 5 , wherein
two positioning slots are defined through the sidewalls and communicate with the insertion space; and the resilient hooking arms are mounted respectively in the positioning slots.

7 . The electrical plug connector as claimed in claim 6 , wherein
the shielding body of the shielding-grounding plate has two mounting holes defined through the shielding body; an upper rear plug bracket is mounted on the rear end of the insulative housing, is mounted above the shielding-grounding plate and has
an upper mounting bracket;
an upper inserting board formed on and protruding forward from the upper mounting bracket and mounted in the assembling slot of the insulative housing; and
an upper mounting protrusion formed on and protruding downward from the upper mounting bracket and mounted in one of the mounting holes of the shielding body of the shielding-grounding plate;
a lower rear plug bracket is mounted on the rear end of the insulative housing, is mounted under the shielding-grounding plate and has
a lower mounting bracket;
a lower inserting board formed on and protruding forward from the lower mounting bracket and mounted in the assembling slot of the insulative housing; and
a lower mounting protrusion formed on and protruding upward from the lower mounting bracket and mounted in the other mounting hole of the shielding body of the shielding-grounding plate.

8 . The electrical plug connector as claimed in claim 7 further comprises a circuit board mounted on the rear end of the insulative housing and having two opposite surfaces respectively connected to the soldering sections of the conductive terminals of the two terminal sets by soldering, wherein one of the opposite surfaces is connected to the soldering tabs of the shielding-grounding plate by soldering.

9 . The electrical plug connector as claimed in claim 8 further comprises an upper shielding cover and a lower shielding cover cooperating to cover the insulative housing, the terminal sets, the upper rear plug bracket, the lower rear plug bracket and the circuit board.

10 . The electrical plug connector as claimed in claim 9 , wherein
the top board has multiple upper terminal recesses and multiple upper through holes defined in the upper inner surface of the top board; the bottom board has multiple lower terminal recesses and multiple lower through holes defined in the lower inner surface of the bottom board; and the conductive terminals of one of the terminal sets are mounted respectively in the upper terminal recesses of the top board of the insulative housing, and the conductive terminals of the other terminal set are mounted respectively in the lower terminal recesses of the bottom board of the insulative housing.
