Abstract: In order to design a cable connection system so as to be operable particularly reliably and to be simultaneously compact, the actuator (1?) is provided at the ends of its actuation arms (122) with an actuation web (123), in the form of a protrusion (13), for reducing friction forces. In order to save on construction space for the collar of an electric cable and for regions of a clamping spring, the actuator (1?) has a receiving opening (120) above the actuation web (123). For the resultantly necessary stabilization, it has stiffening ribs (127) which are integrally formed on the outside of the actuation arms (122). As a result, the actuator (1?) can advantageously be manufactured from plastic and nevertheless have sufficient stability. In addition, the stiffening ribs (127) can be used as an installation aid.

Thus, simple, fast, reliable and shock-resistant connections of a protective conducting wire and an electrical conducting wire are achieved, being suited to installation of not only rigid conducting wire but also flexible conducting wire.

The contact region (KB) has a cylinder wall with at least one radially inwardly folded contact blade (4), the free end of which points towards the pin insertion opening (2).

Abstract: A cable inlet device consists substantially of an open frame part and at least one sealing insert arranged therein. This cable inlet device is attached to a switchgear cabinet so that the sealing insert and the frame part of the cable inlet device terminate flush with the opening. When the switchgear cabinet is closed, for example by a switchgear cabinet door or switchgear cabinet wall or the like, this door or wall is sealingly pressed with a counterpart seal against the cable inlet device. For replacement of cables it is merely necessary for the switchgear cabinet door/switchgear cabinet wall to be opened and for the cable to be changed to be removed together with the corresponding sealing element, and for the new cable to be provided with a matching sealing element and to be inserted.

Abstract: A multi-sensor, real-time, in-process current and voltage estimation system is disclosed including sensors, affiliated hardware, and data processing algorithms that allow accurate estimation of currents and voltages from magnetic and electric field measurements, respectively. Aspects of the system may be embodied in a detector that is readily attachable to conductors of an energized system for contactless current and/or voltage sensing of the conductors without requiring the conductors to be disconnected from the energized system.

Abstract: A holding frame for connector includes different latch and spring elements on opposite side walls of a base frame attached and project with their respective guiding portion whose T- or L-shaped post. The guiding portion ensures through its catching funnel for a comfortable insertion of the connector modules in the correct polarization and thereby, and while holding the then in the holding frame latched connector modules, stabilizing the post. In the construction of the holding frame is a permutation of various latch and spring elements on the base frame by an interaction of their fixing contour with a fixing contour of the respective side wall of the base frame prevented. Due to the special shape of the latch and spring elements, a cable connection-side removal of a connector module is possible if the holding frame is already installed in a commercially available attachment housing.

Abstract: In order to make a cable connection system particularly reliable to operate and compact, an actuator (1) is provided with a rib (123) that is located at an end, guides the actuator along sliding edges (243) of the busbar (2, 2?) and actuates a clamping leg (33) of a V-shaped clamping spring (3, 3?). This reduces friction and creates space for a collar (613, 613?) of the cable (6) at the cable connection end of the rib (123).

Abstract: A locking device for line connectors includes a first housing (10) and a second housing (12) that can be placed against one another in an engagement direction (A). A set of resilient locking tabs (26) are held on the first housing (10) by means of fastening elements and can be latchingly locked on locking projections (32) of the second housing (12).

The fastening elements and the locking projections (32) are in the form of pins (24, 34) that are set in peripheral walls of the two housings (10, 12).

Abstract: In order to be able to equip a contact carrier (1) which is actually provided for receiving screw contacts, i.e. electrical plug contacts having screw connections, with crimp contacts (5) as well, a holding plate (3) can be latched on the contact carrier (1). Said holding plate (3) has a latching arm for each contact chamber of the contact carrier, said latching arm engaging in a screw connection receptacle of the contact chamber. As a result, the crimp contacts (5) inserted on the cable connection side can latch on the latching arm with their holding collar in the contact carrier (1).

Abstract: A ferrule can be assembled in the field. A ferrule collar has a non-circular, in particular polygonal outer contour. A corresponding coding region of a ferrule housing is arranged in a portion of a contact chamber on a cable-connection side and has a non-circular, in particular polygonal cross section, in which the ferrule collar is held with a form fit over the entire spring displacement path. The ferrule spring acts on the ferrule collar over the entire displacement path. As a result, the ferrule is secured against rotation about its axis by a high holding force, which makes it easier for a fibre-optic cable to be screwed on. The structural form is particularly well-suited for use in a plug-in connector module.

The insertion receptacle is tapered in the insertion direction. The base leg (20) of the contact spring transitions into a holding leg (22? 22?), which is inserted into a receiving shaft (30) stationary with respect to the support wall (24) and has two detent projections (38), which protrude perpendicularly to the base leg in opposite directions and are locked to mating contours (34) on the walls of the receiving shaft.
