A contact pin for an electrical plug includes a contact element formed of an electrically conductive material and a contact protection formed of an electrically non-conductive material and at least partially enclosing the contact element. A cooling channel system conducting a cooling fluid is formed in the contact protection. The cooling channel system has a cooling fluid supply and a cooling fluid return connected to the cooling fluid supply in a fluid conducting manner. The fluid cooling channel extends to a distal end of the contact element that faces a mating plug matable with the electrical plug.

An embodiment of a barrier member (102) for use in forming an assembly (100, 200) with an interference fit standard barrier (199) is disclosed. The barrier member (102) comprises a first face (120), a second face (122), a peripheral edge (124) between the first face (120) and the second face (122), the peripheral edge (124) being at least partially angled by an angle (128) relative to a barrier reference line (130) that is perpendicular to both of at least part of the first face (120) and at least part of the second face (122), the angle (128) declining from the first face (120) to the second face (122). The barrier member (102) may further have an interior channel (126) extending through a member depth (123) of the barrier member (102), the member depth (123) being between the first face (120) and the second face (122), the interior channel (126) having a longer length than width in a surface of the first face (120) and a surface of the second face (122), wherein the barrier member (102) is at least partially composed of a polymer.

A connector device according to one or more embodiments includes a male connector including multiple male contact pieces, and a male contact piece retention portion, and a female connector including multiple female contact pieces, and a female contact piece retention portion. The male contact piece retention portion has multiple concentrically formed convex portions. The multiple male contact pieces are mounted on an outer circumferential wall of the convex portions, and arranged concentrically, with a tip end thereof being inclined toward the center of the convex portions. The female contact piece retention portion has concentrically formed multiple concave portions. The multiple female contact pieces are mounted on an inner circumferential wall of the concave portions, and arranged concentrically, with a base end thereof being inclined toward the center of the concave portions. The convex portion and the concave portion are brought into contact and tightly fitted with one another.

A plug main body has an elastic ring installation portion formed on an outer peripheral surface of a cable attachment portion, and a main body side ring support portion formed to have a larger diameter axially adjacent to a front side of the elastic ring installation portion and regulating movement of the elastic ring installation portion to a front side of an elastic ring. A cover side ring support portion is formed in an inner surface of the plug cover, extends radially inward with regard to an axis of the main terminal portion and comes into contact with a rear side outer surface of the elastic ring. The elastic ring is axially compressed between the main body side ring support portion and the cover side ring support portion, and the front end surface of the plug cover is directly brought into contact with the rear end surface of the flange.

An electrical connector comprises a housing defining a receiving slot adapted to receive a pin of a cluster block, and a connection terminal provided in the housing. At least one of the housing or the connection terminal defines an anti-shaking structure adapted to prevent the shaking of the electric connector with respect to the cluster block when the electrical connector is coupled with the cluster block.
