Definitions
- the invention relates to a connection lemme with a first clamping means, which is provided with a clamping piece, a clamping screw and a clamping frame, the clamping frame having a first and a second leg and a first receiving space for at least one conductor.
- a connection or connection terminal is used to connect, connect and branch one or more current paths that are not interrupted during operation.
- connection lemme which is designed as a universal connection terminal.
- the invention has for its object to provide a connection lemme, in which a further connection possibility should be given.
- connection lemme known from the prior art
- a subdivided receiving space is assumed, so that there are multiple connection options.
- the inventive idea on which the new idea is based is to form a further recording space outside of this recording space, the legs which have hitherto only served as a frame closure being included.
- a connecting terminal of the type mentioned in which, according to the invention, the two legs form a second terminal with their second end with a second receiving space.
- the invention is particularly suitable for modular devices, such as a relay, a contactor, a circuit breaker, a circuit breaker or motor circuit breaker.
- the second clamping means is advantageously designed as a gripper-like gripper.
- the second receiving space which is open on one side, can either insert or insert a conductor into the second clamping means or, in the opposite case, the second clamping means can be plugged onto a conductor.
- the open second receiving space also offers the possibility of a visual inspection with regard to the conductor position and / or the contacting.
- the connection terminal thus offers several connection options for different ones
- the second clamping means can be used with the pliers-like gripper alone or in combination with the first clamping means.
- the manufacture and use of the pure gripper-like gripper itself is also possible.
- the first leg is guided through the second leg. This enables a favorable geometric, essentially inherently rigid design of the gripper-like gripper. Depending on the conductor, there can also be a form-fitting conductor clamp.
- the two legs cross each other.
- a reduced-cut variant of the gripper-like gripper can advantageously be implemented.
- the first leg has an opening for receiving a conductor.
- a conductor that is not stripped, in particular with a small conductor cross section, can advantageously be inserted into this opening for connection.
- This embodiment is particularly well suited for solid conductors.
- the gripper-like gripper advantageously has at least one cutting edge, as a result of which non-stripped conductors can also be introduced, contacted and clamped without the need for an additional terminal component.
- the elimination of additional cutting parts has a cost-effective effect.
- the two legs are advantageously designed as spring means, so that a repeated connection and disconnection of a conductor is given by the self-resetting, pliers-like gripper. Possibly. Additional spring means required can thus be saved.
- the first receiving space expediently comprises a clamping wedge, which enables the force to be transmitted from the clamping screw to the gripper-like gripper.
- FIG. 1 shows a connection terminal with a first and a second clamping means in a side view
- FIG. 2 shows a connection terminal according to FIG
- FIG. 3 shows a second clamping means of a connecting terminal according to FIG. 1 in a side view
- FIG. 4 shows a development of the second clamping means according to FIG. 3 in a top view
- 5 to 7 a connecting terminal according to FIG. 1 in a housing section in different views
- FIGS. 8 to 10 a connecting terminal according to FIG. 1 with a conductor inserted in a second clamping means in different views
- FIGS. 14 to 16 a connecting terminal according to FIG. 1 with a first clamped in a first clamping means
- FIGS. 20 to 22 show an alternative embodiment of a connecting terminal according to FIG different views.
- the first and the second clamping means 2 and 3 show a connecting 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 clamping piece 4 and a clamping screw 5.
- the first clamping means 2 comprises a clamping frame 6, which has a first and a second leg 7 or 8 and a first receiving space 9 for at least one conductor.
- the first receiving space 9 comprises a clamping wedge 10, which can also be part of a device as a fixed connection.
- legs 7, 8 form the second clamping means 3 with a second receiving space 13 for at least one further conductor.
- the clamping 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 clamping piece 4.
- the clamping frame 6 has a second guide 20 with an internal thread, in which the clamping screw 5 is guided.
- the clamping frame 6 has an approximately rectangular profile, the legs 7, 8 forming the clamping frame 6 being diagonally angled to one another on the side opposite the clamping piece 4.
- the second leg 8 is guided at the end through an opening 21 of the first leg 7 which is not shown here.
- the free ends 11, 12 each have at least one cutting edge 22 on the sides facing the second receiving space 13.
- the two legs 7, 8 designed as spring means can also cross or overlap.
- the first clamping means 2 and the first receiving space 9 are closed and are generally used for clamping or for take customary prepared conductors of different cross-sections.
- the second clamping means 3 and the second receiving space 13 are open on one side and can be compared to the first
- Recording space 9 can also be used for receiving non-stripped conductors.
- the first receiving space 9 is from the second
- the second clamping means 3 is designed as scissors-like or pincer-like free ends 11, 12 as pincer-like grippers.
- the cutting edges 22 offer an additional quasi-positive fit against pulling out the conductor.
- the fixed cutting edges 22 of the second clamping means 3 can possibly be plugged onto a conductor without actuating the clamping screw 5, since the second clamping means 3, designed as a gripper-like gripper, is open on one side.
- the cutting edges 22 can be made from a special material and / or can be designed as contact surfaces.
- the conductor then applies the clamping pressure to the clamping Wedge 10 continues so that both the first and the second clamping means 2 and 3 are actuated.
- This clamping process can also take place without a conductor arranged in the second receiving space 13, since the two free ends 11, 12 are then pressed onto one another and the clamping frame 6 thus has a sufficiently high inherent rigidity to be able to clamp a conductor in the first clamping means 2.
- the gripper-like gripper In the unactuated position of terminal 1, the so-called rest position, the gripper-like gripper is open. 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 gripper-like gripper of the second clamping means 3 springs back into 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.
- FIG. 3 shows the second clamping means 3 according to FIG. 1, the first leg 7 having a passage 23a for receiving a conductor.
- an extension 24 is shown with a further passage 23b.
- the opening 21 in the first leg 7 for the passage of the second leg 8 is made approximately square.
- the opening 21 can be formed up to the edge of the material - as indicated by the two incisions 21a, 21b - so that a lateral passing of the second leg 8 past the first leg 7 is facilitated.
- connection terminal 1 shows the connection terminal 1 according to FIG. 1 in a housing section 25 in a three-dimensional view, the first and the second clamping means 2 and 3 being opened and thus shown unactuated.
- 6 and 7 the connection terminal me 1 shown in FIG 5 in a sectional view or in a side view.
- FIG. 8 shows the connection terminal 1 according to FIG. 1 with a conductor inserted in the second clamping means 3 in a three-dimensional view, the first clamping means 2 being shown screwed close to the stop.
- FIGS. 9 and 10 show the connection terminal 1 according to FIG. 8 in a side view and in a sectional illustration.
- FIG. 11 shows the connection terminal 1 according to FIG. 1 with a conductor clamped in the second clamping means 3 in a three-dimensional view, the first clamping means 2 being shown screwed to the stop.
- the connection terminal 1 according to FIG. 11 is shown in a side view and in a sectional view.
- FIG. 14 shows the connection terminal 1 according to FIG. 1 with a first conductor clamped in the first clamping means 2 and with a second conductor clamped in the second clamping means 3 in a three-dimensional view. 15 and 16, the connection terminal 1 according to FIG. 14 is shown in a side view and in a sectional view.
- connection terminal 1 according to FIG. 17 shows the connection terminal 1 according to FIG. 1 with a conductor clamped in the first clamping means 2 in a three-dimensional view, the second clamping means 3 being shown screwed on as far as it will go.
- the connection terminal 1 according to FIG. 17 is shown in a side view and in a sectional view. From the representations described above it follows that both recording spaces can be used as desired, independently of one another.
- 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.
- 20 shows an alternative embodiment of the connection terminal 1 according to FIG. 1.
- the U-shaped clamping frame 6 is formed from a flat material and has two free legs 7, 8.
- the free legs 7, 8 of the clamping frame 6 are provided with a plurality of elongated openings 21 in their course, the angular legs 7, 8 crossing one another and intersecting each other in the form of mutually offset slats 26, forming a closed second receiving space 13 for at least one conductor ,
- a relative movement or displacement between the clamping frame 6 and the clamping wedge 10 is given by the introduction of a clamping force by means of the clamping screw 5, eccentric or wedge.
- the resulting clamping movement of the connecting terminal 1 is similar to a shear mechanism, the clamping force being able to build up only when a conductor is inserted into the second receiving space 13.
- a largely extensive stripping of a conductor inserted into the second receiving space 13 can thereby be effected.
- Burrs that may remain on the slats 26 after a punching or lasering process act as cutting edges 22 when the conductor is clamped. there is only a small notch effect and conductor deformation as well as a low risk of conductor breakage.
- 21 and 22 show the connection terminal 1 according to FIG. 20 in a side view with or without a clamped conductor.
- An essential idea of the present idea is to advantageously use a lifting movement caused by the tightening of the clamping screw 5 in a pliers movement transversely to the longitudinal axis LA of the clamping screws 5 for stripping and / or for contacting a conductor.
- 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.
