A junction box including a box body and a conductive bar. A guide plate extends from a lead insertion opening, with a laterally extended connection portion at its extended end to connect the box body. First and second support plates and edges of the guiding plate form passages accessible to a lead insert space defined by the guiding plate, the connecting portion, the second support plate and the box body. The conductive bar has a bent conductive arm that moves into the inside of the lead insert space by an elastic force, therefore locked in said space, after it passes the passages.

A contact insert for a connecting terminal, wherein the contact insert has a busbar piece and a clamping spring for clamping an electrical conductor in a conductor insertion direction, wherein the busbar piece and the clamping spring form a clamping point for the electrical conductor to be clamped, and wherein the contact insert has a bushing contact for receiving a contact pin. The longitudinal extension direction of the bushing contact runs essentially perpendicular to the conductor insertion direction from the busbar piece. The bushing contact is designed to receive the contact pin perpendicular to the longitudinal extension direction of the bushing contact and to receive the contact pin in the longitudinal extension direction of the bushing contact.

A two-points-and-one-line push-in terminal capable of secure positioning includes a terminal body and a busbar, and can be mounted in a housing to form a connector. The terminal body is formed by stamping and bending an elastic metal plate, has a U-shaped longitudinal cross section, and includes a front upstanding insertion leg, a horizontal joining foot, and a rear upstanding insertion leg. The elastic metal plate can be divided by at least two slits into at least four independent sections, each having a U-shaped slit defining a pressing spring finger and a pressing frame. The busbar can be mounted on the horizontal joining foot. An electric wire can be passed through a corresponding pair of the U-shaped slits so as to abut against the free ends of the corresponding pressing spring fingers and the busbar and be restrained in the corresponding pressing frames, which serves as the two-points-and-one-line positioning mechanism.
