Embodiment Construction

[0071] figure 1 A series termination comprising an insulator 1 is shown, consisting of a plurality of segments 11 . Each segment 11 has a plurality of cable inlets 111 and one screw opening 112 for each cable inlet 111 .

[0072] figure 2 In particular, a cross section is shown of an individual section 11 of the insulating body 1 , which comprises four busbars 2 exemplarily inserted therein and four parallel screw connections 3 likewise inserted by way of example, which each have a connection housing. 31 and joint bolts 32 , wherein the ends of the respective bus bars 2 are arranged in the respective joint housings 31 of the screw joints 3 . In this way, the individual busbars 2 are arranged at least partially in the section 11 of the insulating body 1 and thus also in the insulating body 1 . Furthermore, the respective busbar 2 is arranged at least partially in the respective connection housing 31 of the screw connection 3 .

Abstract

In parallel screw connections (3), which are preferably used in series terminals, the transmission of force from the connection screw (32) to electric conductors (41) which have different diameters is not always optimal. As a solution, the clamping element (33) is mounted in or on the connection housing (31) both in a movable manner as well as in a rotational manner about a rotational axis (333). By screwing the connection screw (32), the clamping element (33) is moved in the direction of the electric conductor (41), mechanically contacts the electric conductor (41), is rotated by further screwing the connection screw (32) about the rotational axis (333), and thus presses the electric conductor (41) against the busbar (2) with a corresponding degree of force. In this manner, an optimal pressing force is ensured independently of the respective diameter of the electric conductor (41).

Description

technical field [0001] The invention relates to a parallel screw joint according to the preamble of independent claim 1 and a device for electrically connecting an electrical conductor to a bus bar (Stromschiene) according to the preamble of independent claim 15. method of contact. [0002] Such screw connections are preferably used in series terminals, which are used, for example, in switch boxes (cabinets). Such screw connections are used in such series terminations for contacting the electrical conductors, in particular the stripped regions of the cables, with the busbars. In this case, the screw connection has a connection screw, the axis of which runs parallel to the inserted electrical conductor for reasons of position and generally also runs parallel to the busbar, which also leads to the designation “parallel screw connection”. Background technique [0003] There are several variants in the prior art such that for the contact of the bus bar with the electrical cond...
