Definitions

• the invention relates to a connecting terminal with a first Klernrnstoff, which is provided with a pressure piece, a clamping screw and a clamping frame, the clamping frame having a first receiving space for at least one conductor, and a clamping piece arranged therein.
• a connection or connection terminal is used to connect, connect and branch one or more current paths that are not interrupted during operation.
• connection terminal which is designed as a universal connection terminal.
• the invention is based on the object of specifying a connection terminal in which a further connection possibility is to be given.
• connection terminal of the type mentioned at the outset in which, according to the invention, the clamping piece has a second receiving space for at least one further conductor, as a result of which a second clamping means is formed.
• the existing clamping piece also allows a simple and therefore inexpensive design of the second clamping means. Basically, there is still a conventional connection option within the first recording room.
• the invention is particularly suitable for modular devices, such as a relay, a contactor, a circuit breaker, a circuit breaker or motor protection switch.
• the clamping piece has a profile with a longitudinal web and a transverse web, which means that a geometrically favorable configuration is provided with simple means.
• This relates in particular to the formation of the second receiving space, to the function of the crossbar as a counterpressure plate for the pressure piece and to the function of the longitudinal web as a stripping and clamping element which can be moved relatively.
• the second receiving space has a shape that resembles a keyhole in such a way that a conductor to be inserted into an insertion area of the receiving space is pressed into a tapering area due to a relative movement between the clamping frame and the clamping piece and is thereby stripped and clamped if necessary ,
• the clamping frame is advantageously provided with an opening for the passage of the longitudinal web of the clamping piece. Due to the precisely fitting opening in connection with the longitudinal web of the clamping piece, an effective shear element is provided which promotes stripping and pinching of a conductor.
• the clamping piece is expediently designed to be fixed to the housing, as a result of which, on the one hand, the connection terminal can be positioned in a housing and, on the other hand, there is an electrical connection to a device or the like.
• the clamping piece is advantageously designed as a stripping means, so that non-stripped conductors can also be inserted into the second receiving space of the connection terminal and can be stripped and clamped during the clamping process.
• FIG 1 shows a terminal with a first and a second Kleitimsch in a side view
• FIG 2 shows a Klekle me according to FIG 1 in a
• FIG. 3 shows a side view of a clamping piece of a connecting terminal according to FIG. 1,
• FIG. 4 shows a development of a clamping piece according to FIG. 3 in a top view
• FIGS. 5 to 7 show a connecting terminal according to FIG. 1 in a housing section in different views.
• the first and the second clamping means 2 and 3 show a connection terminal 1 with a first and a second clamping means 2 and 3.
• the first and the second clamping means 2 and 3 are provided with a pressure piece 4 and a clamping screw 5.
• the first and the second clamping means 2 and 3 have a common clamping frame 6.
• the first Kleitimstoff 2 is provided with a first receiving space 7 for at least one conductor.
• a clamping piece 8 is arranged in the first receiving space 7 and has a second receiving space 9 for at least one whitemon conductor, whereby the second clamping means 3 is formed.
• the clamping piece 8 has a profile with a longitudinal web 10 and a transverse web 11, wherein the second receiving space 9 is given a shape that resembles a horizontally mirrored keyhole.
• the clamping frame 6 is also provided with an opening 12 in which the longitudinal web 10 of the clamping piece 8 is arranged.
• the shape, shape and dimensions of the opening 12 of the clamping frame 6 are adapted to the — possibly also variable — geometry of the longitudinal web 10 in such a way that a precise fit is provided.
• At least one cutting edge 13 is also formed on the contour of the opening 12.
• the pressure piece 4 is U-shaped with a first and a second web 14 or 15, a first guide 16 for the head 17 of the clamping screw 5 being provided in the first web 14.
• the second web 15 serves as a support 18 for the end 19 of the clamping screw 5 opposite the head 17.
• the clamping screw 5 is arranged between the two webs 14, 15.
• the second web 15 engages in the clamping frame 6 arranged at right angles to the pressure piece 4.
• the clamping frame 6 has a second guide 20 with an internal thread, in which the clamping screw 5 is guided.
• first clamping means 2 and 3 as well as the associated receiving spaces 7 and 9 are closed, the first clamping means 2 and the first receiving space 7 generally being used for clamping or for receiving conductors of different cross sections which are usually prepared.
• the second clamping means 3 and the second receiving space 9 can also be used to receive non-isolated conductors. Since the first recording room 7 contains the second receiving space 9, the first receiving space 7 can also be divided into itself.
• a further connection option is also provided by the space in front of and behind the longitudinal web 10, but without making use of the second receiving space 9.
• a clamping of a conductor in the second receiving space 3 is advantageously not dependent on a previous clamping of a conductor in the first receiving space 2. This also applies to conductors to be clamped with different dimensions. Terminal 1 thus offers connection options that are not influenced by relative movements.
• the second receiving space 9 has an insertion region 21 and a tapering region 22 adjoining it. If there is a non-stripped conductor in the insertion area 21 of the second receiving space 9, the conductor is pressed into the tapered area 22 by the previously described movement sequence in such a way that the cutting edge 13 interrupts the insulation of the conductor. Due to the pressure transferred to the conductor by means of the clamping piece 8 and the clamping frame 6, the insulation also bursts on the side opposite the tapering region 22, in particular along the clamped conductor on both sides of the contact points, and flows off laterally. If the conductor core is deformed, this leads to gas-tight contacting of the conductor.
• the cutting edge 13 can extend from the insertion area 21 to the tapering area 22, as a result of which it forms an additional quasi-positive connection against pulling out the conductor.
• the cutting edge 13 can be made from a special material and / or can be designed as a contact surface.
• connection terminal 1 can be used for clamping and, if necessary, for stripping and clamping conductors, the first receiving space 7 being functional even when the second receiving space 9 is not acted on, and vice versa.
• the clamping piece 8 can hold itself automatically in a further embodiment variant, not shown here, by means of spring force at a level in the clamping frame 6 required for the insertion of a conductor. If the terminal 1 is actuated by tightening the clamping screw 5, both clamping means 2 and 3 are activated. When the clamping screw 5 is loosened, the clamping piece 8 is then returned to its starting position. The second clamping means 3 is, so to speak, endeavoring to assume its original position by means of a resilient restoring force.
• the clamping piece 8 according to FIG. 1 is shown as a molded part in a side view or as a development in a top view.
• connection terminal 1 according to FIG. 1 shows the connection terminal 1 according to FIG. 1 in a housing section 23 in a three-dimensional view.
• the first and the second clamping means 2 and 3 are shown closed, each with a conductor inserted in the corresponding receiving space 7 or 9.
• the connection terminal 1 according to FIG. 5 is shown in a side view and in a sectional view.
• the crosspiece 11 can be continued, for example, as a contact extension and can be part of a device as a fixed or housing-fixed connection.
• the two recording rooms can be used as desired, independently of one another.
• An essential idea of the present idea is to advantageously use a lifting movement caused by tightening the clamping screw 5 in two ways for clamping and / or stripping and / or for contacting a conductor.
• connection terminal 1 represents a combination of a conventional clamping means with a further clamping means with a stripping or contacting device. This combination terminal is also functional within the scope of a single clamping means.
• connection terminal can be used, inter alia, in a relay, a contactor, a modular installation device, a circuit breaker, a circuit breaker or motor circuit breaker.
