Apparently, the accompanying drawings in the following description show merely some embodiments of the present invention. In addition, for a better understanding of the present invention, some specific positional terms are used in the following description of embodiments, such as “up”, “down”, “inside”, and “outside”, which are merely designated for displaying in the accompanying drawings with reference to specific embodiments of the present invention, and shall not be understood as a limitation on the embodiments of the present invention.
DESCRIPTION OF EMBODIMENTS
The following clearly describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are merely a part rather than all of the embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
As shown in FIG. 1 to FIG. 12, communication connectors 10 and 20 in a first embodiment of the present invention include insulators 12 and 22, conductive contacts 14 and 24 fixed through the insulators, and wire bodies 16 and 26 in respectively one-to-one connection to the conductive contacts. The conductive contacts 14 and 24 are arranged in arrays to form several conductive contact arrays, each conductive contact array includes several conductive contact groups, and each conductive contact group includes two differential contacts used to transmit a differential signal and one earth contact, where the wire bodies 16 and 26 connected to each conductive contact array form one wire body array, and the wire bodies 16 and 26 connected to each conductive contact group form a wire body group. The communication connector further includes several shielding pieces 18 and 28, where the shielding pieces 18 and 28 are disposed between two neighboring wire body arrays two neighboring wire body arrays, and each shielding piece is not conductively connected to any object and each of the shielding pieces 18 and 28 covers only one wire body group of a same wire body array.
The communication connectors further include pins 19 and 29. The communication connectors may be installed on a circuit board of an electronic device through the pins. The pins are also arranged in arrays to form pin arrays and pin groups respectively corresponding to the conductive contact arrays and the conductive contact groups. The wire bodies 16 and 26 of each wire body group are respectively in on-to-one connection to the conductive contacts 14 and 24 of one conductive contact group and the pins 19 and 29 of one pin group. As being connected to two corresponding conductive contact groups in every two neighboring conductive contact arrays, the two wire body groups are separated by a shielding piece completely, which means that the shielding piece completely separates any conductor group from a surface of another conductor group.
A shape and a size of the shielding pieces 18 and 28 may be adjusted and changed according to specific requirements and situations. As long as the one shielding piece or a combination of multiple shielding pieces completely covers one wire body group and does not cover another wire body group of a same wire body array, a purpose of shielding different arrays in the present invention is achieved. That each shielding piece is not conductively connected to any object means that each shielding piece is neither grounded nor electrically connected to any conductive object. Each wire body group is completely covered by a shielding piece, and the shielding piece that covers one wire body group includes one or multiple shielding pieces. The shielding piece is made of materials with a function of magnetic shielding, which may be metal, such as copper, aluminum, and other metal with a function of electromagnetic shielding.
By disposing a shielding piece between two conductor groups of two neighboring wire body arrays that are respectively connected to two neighboring conductive contact arrays, signal interference between two neighboring conductive contact arrays during transmission may be reduced significantly, and therefore a crosstalk problem between multiple signals of a high-communication connector is solved effectively, thereby ensuring quality of signal transmission in a high-speed scenario. Special reference may be made to FIG. 12, which shows a simulation diagram of crosstalk of a communication connector in the embodiments of the present invention. A dashed line indicates a crosstalk situation of a regular connector, while a solid line indicates a crosstalk situation of a connector in the embodiments of the present invention. It can be seen that, compared with the dashed curve line, the solid curve line is more moderate with a lower peak value, and is more stable in crosstalk, thereby ensuring stability of signal transmission.
