A plug connector for balanced transmission as claimed in claim 1 , wherein said plug-type contact element array has a structure such that plug-type signal contact elements are provided on both ends of said plug-type contact element array, respectively.

Claim 4

A plug connector for balanced transmission as claimed in claim 1 , wherein the plurality of pairs of plug-type signal contact elements are arranged in parallel to each other, in a row.

Claim 5

A plug connector for balanced transmission as claimed in claim 1 , wherein said plug-type signal contact element has a knife-like shape.

Claim 6

A plug connector for balanced transmission as claimed in claim 1 , wherein: said plug-type insulating body includes a plug-type insulating body main part provided with a conductive resin shield part on its inner surface and a plug-type contact element array component capable of being inserted into said plug-type insulating body main part; and said plug-type contact element array is formed on said plug-type contact element array component such that said plug-type contact elements fills grooves formed on said plug-type contact element array component.

Claim 7

A plug connector for balanced transmission as claimed in claim 1 , further comprising plug-type power-supply contact elements.

Claim 8

A connector assembly for balanced transmission comprising: a plug connector for balanced transmission; and a jack connector for balanced transmission, said plug connector comprising: a plug-type contact element array having a plurality of pairs of plug-type signal contact elements and a plurality of plug-type ground contact elements arranged alternately with said plurality of pairs of plug-type signal contact elements said array being configured such that each end element of said plug-type contact element array comprises one of the pairs of plug-type signal contact elements, and a plug-type insulating body made of an electrically insulating material for supporting said plug-type contact element array; said jack connector comprising: a jack-type contact element array having a plurality of pairs of jack-type signal contact elements and a plurality of jack-type ground contact elements arranged alternately with said plurality of pairs of jack-type signal contact elements, and a jack-type insulating body made of an electrically insulating material for supporting said jack-type contact element array; and a pitch between each said end element pair of plug-type signal contact elements and a plug-type ground contact element adjacent thereto is smaller than a pitch between each of the remaining plug-type signal contact element pairs and a plug-type ground contact element adjacent thereto.

Claim 9

A connector assembly for balanced transmission comprising: a plug connector for balanced transmission; and a jack connector for balanced transmission, said plug connector comprising: a plug-type contact element array having a plurality of pairs of plug-type signal contact elements and a plurality of plug-type ground contact elements arranged alternately with said plurality of pairs of plug-type signal contact elements said array being configured such that each end element of said plug-type contact element array comprises one of the pairs of plug-type signal contact elements, and a plug-type insulating body made of an electrically insulating material for supporting said plug-type contact element array; said jack connector comprising: a jack-type contact element array having a plurality of pairs of jack-type signal contact elements and a plurality of jack-type ground contact elements arranged alternately with said plurality of pairs of jack-type signal contact elements, and a jack-type insulating body made of an electrically insulating material for supporting said jack-type contact element array; and a pitch between each said end element pair of plug-type signal contact elements and a plug-type ground contact element adjacent thereto is smaller than a pitch between each of the remaining plug-type signal contact element pairs and a plug-type ground contact element adjacent thereto.

Claim 10

A connector assembly for balanced transmission as claimed in claim 7 , wherein said plug-type contact element array has a structure such that plug-type signal contact elements are provided on both ends of said plug-type contact element array, respectively.

Claim 11

A connector assembly for balanced transmission as claimed in claim 7 , wherein the plurality of pairs of plug-type signal contact elements are arranged in parallel to each other, in a row.

Claim 12

A connector assembly for balanced transmission as claimed in claim 7 , wherein said plug-type signal contact element has a knife-like shape and said jack-type signal contact elements has fork-like shape.

Claim 13

A connector assembly for balanced transmission as claimed in claim 7 , wherein said plug connector further comprises plug-type power-supply contact elements and said jack connector further comprises jack-type power-supply contact elements.
