Abstract

A plug connector includes an electrically insulating body including a housing and a pair of arms; a plurality of pairs of first and second right-angled signal contact elements supported by the housing such that the first right-angled signal contact element is arranged above the second right-angled signal contact element, each of the right-angled signal contact elements having a substantially right-angled contact portion protruding backward from the housing and a leading portion inserted into the housing, the contact portion having a horizontal part and a vertical part; a plurality of ground contact elements supported by the housing and disposed alternately with the plurality of pairs of first and second right-angled plug signal contacts, each of the ground contact elements provided with two ground terminals; and upper and lower electrically insulating brackets assembled to the housing. The upper bracket covering the horizontal parts of the plurality of first signal contact elements, the lower bracket covering the horizontal parts of the plurality of second signal contact elements, and the lower bracket being provided with holes into which the vertical parts of the first and second signal contact elements and the ground terminals are inserted.

Claims

1. A plug connector comprising:

an electrically insulating body including a housing and a pair of arms;

a plurality of pairs of first right-angled signal contact elements and second right-angled signal contact elements, which pairs are supported by the housing such that the first right-angled signal contact elements are arranged above the second right-angled signal contact elements, each of said plurality of pairs of first right-analed signal contact elements and second right-angled signal contact elements having a substantially right-angled contact portion protruding backward from said housing and a leading portion inserted into the housing, said contact portion having a horizontal part and a vertical part;

a plurality of ground contact elements supported by said housing and disposed alternately with said plurality of pairs of first right-angled signal contact elements and second right-angled signal contact elements, each of said ground contact elements provided with two ground terminals; and

upper and lower electrically insulating brackets assembled to said housing,

wherein said upper bracket covers said horizontal parts of the first right-angled signal contact elements, said lower bracket covers said horizontal parts of the second right-angled signal contact elements, and said lower bracket being provided with holes into which said vertical parts of said plurality of pairs of first right-angled signal contact elements and second second right-angled signal contact elements and said ground terminals are inserted,

wherein said upper bracket is provided with a plurality of upper-bracket signal contact grooves at a lower surface, each of said upper-bracket signal contact grooves having a shape corresponding to the horizontal part of said first signal contact element, and

said lower bracket is provided with a plurality of lower-bracket signal contact grooves at an upper surface, each of said lower-bracket signal contact grooves having a shape corresponding to the horizontal part of said second signal contact element,

each of said upper-bracket signal contact grooves having the horizontal part of said first right-angled signal contact element disposed therein, and each of said lower-bracket signal contact grooves having the horizontal part of said second right-angled signal contact element disposed therein.

2. The plug connector as claimed in claim 1,

further comprising a cavity formed between the upper bracket and the lower bracket assembled to said housing, and between the horizontal part of said first right-angled signal contact element and the horizontal part of said second right-angled signal contact element, said cavity being filled with an electrically insulating material.

3. The plug connector as claimed in claim 1,

wherein said upper bracket is provided with a plurality of upper-bracket signal contact grooves on its lower surface, each of said upper-bracket signal contact grooves having a shape corresponding to the horizontal part of said first right-angled signal contact element,

said lower bracket is provided with a plurality of lower-bracket signal contact grooves on its upper surface, each of said lower-bracket signal contact grooves having a shape corresponding to the horizontal part of said second right-angled signal contact element,

each of said upper-bracket signal contact grooves having the horizontal part of said first right-angled signal contact element disposed therein, and each of said lower-bracket signal contact groove having the horizontal part of said second right-angled signal contact element disposed therein;

said plug connector further comprising a cavity formed between the upper bracket and the lower bracket assembled to said housing, and between the horizontal part of said first right-angled signal contact element and the horizont element, said cavity being filled with an electrically insulating material.

4. The plug connector as claimed in claim 1,

wherein the horizontal part of said second right-angled signal contact element is provided with a length adjusting part having a cranked shape.

5. The plug connector as claimed in claim 1,

wherein each of said plurality of ground contact elements has an extension protruding backward from said housing and a leading portion to be inserted into the housing, said extension having a size covering a projection area of the right-angled contact portions of the pair of first right-angled signal contact elements and second right-angled signal contact elements, said extension having an upper half part and a lower half part.

6. The plug connector as claimed in claim 5,

wherein said upper bracket is provided with a plurality of upper-bracket ground contact grooves on its lower surface, each of said upper-bracket ground contact grooves having a shape corresponding to the upper half part of said extension of said ground contact element,

said lower bracket is provided with a plurality of lower-bracket ground contact grooves on its upper surface, each of said lower-bracket ground contact grooves having a shape corresponding to the lower half part of said extension of said ground contact element,

each of said upper-bracket ground contact grooves having the upper half part of said extension of said ground contact element disposed therein, and each of said lower-bracket ground contact grooves having the lower half part of said extension of said ground contact element disposed therein.

7. The plug connector as claimed in claim 1,

further comprising an upper shielding member and a lower shielding member,

said upper shielding member including an L-shaped body part and upper shield terminals, said body part including a rectangular horizontal shielding plate part provided on an upper side of the housing and a rectangular vertical shielding plate part covering a backside of said upper bracket and a backside of said lower bracket, and said lower shielding member including a shield plate part of a rectangular shape and lower shield terminals.
