A connection unit includes an insulating mounting frame and multiple resilient press-on contacts situated on the mounting frame. Each press-on contact includes a helical pressure spring that can exert an elastic force on a metal contact body. The contact body is connected in one piece to a connection plug or a connection socket. For each press-on contact, the mounting frame includes a hollow cylinder that forms a cavity within a circumferential wall, the cavity being closed off by a cover that is situated so as to be axially displaceable at the wall of the hollow cylinder. The pressure spring is situated inside the cavity, and with its elastic force acts on the cover. The contact body, in one piece, forms a contact disk that is situated on the outer side of the cover.

An electrical connector includes an insulating seat and at least one conductive terminal provided therein. The insulating seat includes a rear wall and two side walls, surroundingly forming a mating space. Each side wall includes an extending arm and an elastic arm. The elastic arm has a first arm extending forward from the extending arm and a second arm bending reversely from the first arm and extending backward. The second arm is connected to the rear wall. An opening slot is formed between the first arm and the extending arm and runs forward therethrough. A through slot is formed between the second arm and the first arm. A buckling portion is formed at a side of the second arm away from the first arm to correspond to the through slot and the opening slot in a left-right direction. The conductive terminal has a contact portion exposed to the mating space.
