JP2015-125861A

  However, in the connector described in Patent Document 1, if the pressing force (spring force) by the elastic contact piece is too strong, the surface of the male terminal or the surface of the elastic contact piece in the female terminal is worn when the male terminal is inserted. There is a risk that such a problem occurs that the plating applied to the terminal is peeled off.

  When the pressing force (spring force) by the elastic contact piece is reduced to suppress terminal wear, sufficient pressing force does not act between the male terminal and the elastic contact piece. There is a risk that problems such as displacement and increase in contact resistance between both terminals may occur.

  Thus, in order to suppress the displacement of the terminal and the increase in contact resistance due to vibration, it is necessary to increase the pressing force (spring force) applied between both terminals. When the pressing force applied between them is increased, there is a problem that the terminal is worn.

  Then, an object of this invention is to provide the connector which can suppress abrasion of a terminal, raising the pressing force between terminals.

  In order to solve the above problems, the present invention provides a first connector portion in which a pin-shaped male terminal is accommodated in the first housing, and a first female portion in which a cylindrical female terminal is accommodated in the second housing. 2 connector parts, and in a state where both the housings are fitted, the male terminal is inserted into the female terminal and the both terminals are electrically connected, and the female terminal is A cylindrical base end portion, and a terminal insertion portion having a plurality of contact pieces extending from the base end portion to the insertion side of the male terminal, wherein the plurality of contact pieces are arranged in a cylindrical shape, The second housing is configured to be slidable in the fitting direction of the two housings with respect to the female terminal, and the second connector portion is provided to slide together with the second housing. The pressing member The pressing member, as the second housing slides, contacts the outer peripheral surface of the male terminal by pressing the contact piece inward and a non-pressing position where no pressing force is applied to the contact piece. A connector configured to slide between a pressed position is provided.
