Connector with pair of terminals and coupling portion
A board connector includes a pair of inner terminals. The board connector includes a terminal body. Further, the board connector includes a low-dielectric constant portion having a relative dielectric constant set to be lower than that of the terminal body and interposed between the intermediate extending portion of one of the inner terminals and the intermediate extending portion of the other one of the inner terminals. An spacing between the intermediate extending portion of the one inner terminal and the intermediate extending portion of the other inner terminal is set to be smaller than at least one of an spacing between the fitting-side extending portion of the one inner terminal and the fitting-side extending portion of the other inner terminal or an spacing between the board-side extending portion of the one inner terminal and the board-side extending portion of the other inner terminal.
1 . A connector comprising:
a pair of terminals comprising a first terminal and a second terminal, each of which includes a first connecting portion to which a first connection target object is connected, a second connecting portion to which a second connection target object is connected, and a coupling portion that couples the first connecting portion and the second connecting portion to each other, the pair of terminals being arranged with a spacing therebetween and a differential signal being transmitted via the pair of terminals;
a dielectric portion that holds the pair of terminals; and
a low-dielectric constant portion that has a lower relative dielectric constant than a relative dielectric constant of the dielectric portion and that is interposed between the coupling portion the first terminal and the coupling portion of the second terminal,
wherein a spacing between the coupling portion of the first terminal and the coupling portion of the second terminal is smaller than at least one of a spacing between the first connecting portion of the first terminal and the first connecting portion of the second terminal or a spacing between the second connecting portion of the first terminal and the second connecting portion of the second terminal, and
wherein an intermediate portion of the coupling portion of the first terminal bulges only toward an opposite side from a side of the low-dielectric constant portion, and a width of the intermediate portion of the coupling portion of the first terminal is larger than a width of either of respective end portions of the coupling portion of the first terminal.
2 . The connector according to claim 1 , wherein:
the pair of terminals is held in a state of being embedded in the dielectric portion, and
the low-dielectric constant portion is a gap formed between the coupling portion of the first terminal and the coupling portion of the second terminal.
3 . The connector according to claim 1 , wherein the dielectric portion includes a cover portion which covers part of the coupling portion of the second terminal at a side opposite from the low-dielectric constant portion.
4 . A connector, comprising:
a pair of terminals comprising a first terminal and a second terminal, each of which includes a first connecting portion to which a first connection target object is connected, a second connecting portion to which a second connection target object is connected, and a coupling portion that couples together the first connecting portion and the second connecting portion, the pair of terminals being arranged with a spacing therebetween and a differential signal being transmitted via the pair of terminals;
a dielectric portion that holds the pair of terminals; and
a low-dielectric constant portion that has a lower relative dielectric constant than a relative dielectric constant of the dielectric portion and that is interposed between the coupling portion of the first terminal and the coupling portion of the second terminal,
wherein a spacing between the coupling portion of the first terminal and the coupling portion of the second terminal is smaller than at least one of a spacing between the first connecting portion of the first terminal and the first connecting portion of the second terminal or a spacing between the second connecting portion of the first terminal and the second connecting portion of the second terminal, and
wherein an intermediate portion of the coupling portion of the second terminal comprises a first portion that is substantially parallel to the coupling portion of the first terminal, a second portion that extends from the first portion toward the coupling portion of the first terminal such that an entire width of the second portion approaches the coupling portion of the first terminal, and a third portion that extends from the first portion such that an entire width of the third portion withdraws from the coupling portion of the first terminal.
