A flat plug-in connector assembly includes a flat contact, a mating plug connector, and a contact chamber. The flat contact has a middle strip having opposite first and second sides and further has a first end that forms a blade contact section. The mating plug connector includes a pair of contact springs for accommodating the blade contact section. The flat contact further includes first and second spring arms for damping relative movements between the blade contact section and the contact springs. The first and second spring arms are integrally formed in one piece at the first and second sides of the flat contact. The first and second spring arms have first and second free end sections in a form of first and second detent hooks. The flat contact is inserted in the contact chamber with the first and second detent hooks being displaceable supported in the contact chamber.

A unipolar connection terminal for a high-voltage connector and a connector device are provided in the invention. The unipolar connection terminal is mounted in a housing of the connector device. The connector device has a columnar insertion tube to be connected and passed through by a mating terminal, an end portion of the insertion tube extends in a radial direction to form at least three protrusion structures, and the at least three protrusion structures are arranged at intervals in a circumferential direction of an end surface of the insertion tube. According to the unipolar connection terminal and the connector device provided by the invention, when the unipolar connection terminal is mounted in the housing of the connector device, an erroneous assembly can be effectively avoided due to the arrangement of the protruding structures disposed at the end portion of the insertion tube, and a conduction effect of the connector device is guaranteed.

A connector includes a housing defining a terminal holding chamber extending in a prescribed direction, a terminal member inserted to the terminal holding chamber along a prescribed insertion direction, and a retainer attached to the housing by being inserted to the housing along a direction perpendicular to the insertion direction so as to engage with a locking portion of the terminal member and thereby prevent the terminal member from coming off, wherein the terminal member is a bent article made of a plate material including a protruding portion having a top portion on one side in the direction along which the retainer is inserted to the housing, and the protruding portion has an end surface facing in the insertion direction of the terminal member and constituting the locking portion.
