Definitions
- the invention relates to a terminal for an electrical installation device according to the preamble of claim 1.
- a circuit breaker a residual current circuit breaker, is used as the installation device or any other installation device in which such terminals are provided.
- connection terminal which has a box-shaped terminal frame, the one receiving the clamping screw Wall are formed by two superimposed web ends, being on the web projections are provided which in the side walls of the clamping frame be inserted or pressed in so that the clamping frame becomes jammed not deformed.
- a terminal has also become known in which an annular box frame and an annular clamp frame are intertwined, wherein the clamping screw, which is screwed into the terminal frame, a web of the Reaches through the box frame. Between the box frame and the terminal frame on the one hand and the web and the head of the clamping screw on the other hand can be electrical Connection elements are clamped.
- connection line With the usual terminals used in a circuit breaker, is, as already indicated, the terminal lug of a busbar between the Screw head and the upper web of the box frame inserted and clamped in it; on the other hand, the connection line, seen from the front, is behind attached to the busbar. For example, if a three-phase busbar block is clamped, then it can no longer be seen whether the connecting conductor is correctly clamped. This can result in incorrect connections.
- a screw terminal has become known rectangular, frame-shaped clamp part and a U-shaped pressure piece, wherein a frame part can be inserted or inserted into the terminal part, so that are generated by the frame part two connecting conductor receiving spaces, in the different Connection conductor inserted and clamped in it.
- This Screw terminal consists of three parts, namely the U-shaped pressure piece, the frame-shaped clamp part and the frame part.
- US 4,526,437 A1 describes a connector made from a u-shaped band is that the leg ends are bent into a cylindrical shape. The inner The cylindrical shape has an internal thread and around the cylindrical shape a ring is arranged, which expands when the clamping screw is screwed in should prevent.
- the object of the invention is to provide a terminal for an installation switch to create the type mentioned, in which the disadvantages of the known terminals prevents and incorrect connections are avoided; Furthermore the terminal should be designed with fewer parts.
- the clamp body has a cylindrical shape, which at one end Internal thread for receiving the clamping screw and on opposite Surface lines axially extending slots, the length of which is less than the length of the Terminal body, through which the terminal lug of the busbar and / or the lead wire can be inserted into the terminal.
- the clamping screw is as Headless stud bolt (stud or grub screw) that is fully formed in the terminal body can be screwed in.
- a clamping piece is inserted into the clamp body, the two Divide terminal spaces from each other, so that the lead wire in each terminal space and / or the terminal lug can be inserted and clamped therein.
- the clamping piece can then at least on the terminal surface that the Clamping screw is facing, be V-shaped; this creates a gutter, in which the lead wire is guided against rotation. That means that when screwing the clamping screw the lead wire related to the clamping piece not is twisted.
- the clamping piece is preferably bent rectangular and has an elongated Tab that reaches through an opening into the interior of the installation switch, so that an inner conductor of the installation switch can be connected to it.
- a pressure piece of the clamping screw assigned is preferably a pressure piece of the clamping screw assigned.
- the terminal requires a few openings on the installation device, such as an opening at the top the front, through which the clamping screw is accessible, then further Openings on the side wall through which the connecting conductor or the connecting lug can be inserted into the terminal.
- the opening is through the connector is inserted closer to the front than the opening through which the connecting lug is inserted. This enables the conductor connections are more accessible and more visible, especially in multi-row Distributions.
- a major advantage is that accessibility and visibility the conductor connections in multi-row distributions are significantly improved. Furthermore the permissible torque is also higher when a conductor is jammed, which is due to the fact that the screw in a thread within the Leg, so the cylindrical shape is guided. Because in this version the thread pitch can be increased, the number of screw revolutions can be reduced, which are required to fix the conductor.
- FIG. 1 shows a clamp 10 with a clamp body 11, a clamp screw 12 and a clamping piece 13, which is drawn outside the clamp body, is shown.
- 1 belongs to the terminal body 11 to the state of the art, such as has become known from US-4,526,437.
- the arrangement shown in FIG. 1 differs from that according to the invention in that the clamping body (see Fig. 4) is cylindrical. Like beyond that Clamping piece 13 and the clamping screw 12 are inserted into the clamp body according to FIG. 4 are shown in FIG. 1.
- the clamp body 11 has a U-shape with a web 14 and thereon adjoining legs 15 and 16, which in the web 14 adjacent area 17 and 18 straight or flat and perpendicular to the also flat Are aligned.
- the flat sections 17 and 18 follow sections 19 and 20 of arcuate and curved design in cross section, which complement each other in a cylindrical shape, the central axis of which is perpendicular to the web and on the inner surface of which an internal thread 21 is attached.
- the free ends of the Leg sections 19 and 20 have webs 22, 23; 24, 25, which also complement each other to form a circle in cross-section and also on the inside carry the internal thread 21.
- the webs 22, 23; 24, 25 welded together, for example by means of laser welding or electron beam welding.
- the web 14 has an L-shaped flag 26, the vertical extending to the plane of the web 14 and in to the legs 15 and 16 opposite leg 27 projecting a T-shaped extension 28 owns.
- the clamping piece 13 is inserted, which one in Cross-section rectangular, the contour adapted section 29, with a lower and upper side level 30, 31, a web 32 and a web 33, the web 33 is surmounted by a tab 34 which lies in the extension of the side wall 30 and in the assembled state for connecting inner conductors within the installation switching device, that holds the clamp serves.
- the web 33 are on both sides, the longitudinal edge the side wall 30 with the tab 34 protruding, stops 35, 36 formed.
- the clamping piece 13 according to FIG. 1 can be manufactured in that an elongated Copper tape with the two flags 35 and 36 at one end by rolling up to it rectangular cross section is formed. With the web 32 first, the clamping piece in pushed the area between the two leg sections 17 and 18. The clamping piece 13 can also between up in the region of the thread 21 the two sections 19 and 20 are pushed up.
