Description

The present invention relates to a conductor terminal with a housing, a pivoting lever, a current bar accessible via an insertion opening in the housing, and a clamping spring, the pivoting lever having a pusher element and being pivotable with respect to the housing between an open position and a closed position, the clamping spring having a holding leg and has a clamping leg connected to it via a flexible joint, wherein in the closed position of the pivoted lever a conductor inserted into the housing via the insertion opening can be subjected to a force on the current bar by means of the clamping leg located in a clamped position, and wherein when the pivoted lever is transferred into its open position the clamping leg by means of which is pushed away with this in direct and immediate contact pusher element under tension build-up in the clamping spring from the power bar in a release position, and wherein the pivoting lever in the housing dre hbar-mounted axle strut, about which the pivoting lever can be pivoted between the open position and the closed position.

Conductor connection terminals are known from the prior art, by means of which, for example, two electrical conductors can be connected to one another.

So reveals the DE 10 2013 101 406 A1 a conductor terminal with a housing in which a number of pivoting levers, current bars and clamping springs corresponding to the number of poles are provided. The housing comprises a plurality of insertion openings located next to one another, into which conductors to be electrically connected to one another can be inserted. The pivoted levers each have pivot bearings that are rotatably mounted and positioned on the current bar, with each pivot bearing having an actuating section. The clamping springs each have a holding leg and a clamping leg connected to it by means of a flexible joint. In a closed position of the pivoted lever, the clamping leg of the clamping spring rests on the current bar. By transferring the pivoting lever into its open position, the clamping leg of the clamping spring is pushed away from the current bar into a release position by means of the actuating section of the pivot bearing, with tension building up in the clamping spring.

By means of the DE 10 2013 101 406 A1 known conductor terminal, only conductors with a small conductor cross-section can be clamped. So that conductors with a larger cross section can also be clamped and electrically contacted, the dimensions of the conductor connection clamp, in particular their height, must be increased considerably. Furthermore, the consists of the DE 10 2013 101 406 A1 known conductor terminal, the risk that the clamping lever located in the open position due to the pressure exerted by the clamping spring moves independently in the direction of the closed position. Consequently, to contact and clamp a conductor, the pivoted lever must always be held manually in its open position, and only after the conductor has been placed in the conductor connection terminal and the pivoted lever pivoted into its closed position can it be released by the operator.

From the DE 15 75 118 A a screwless connection terminal for electrical devices is known, which has a leaf spring arranged in a housing, locking the conductor at an angle to the direction of insertion, and a lever releasing the lock. The lever is mounted in the housing so that it can be tilted.

In the DE 10 2008 017 245 A1 discloses a plug-in adapter for plugging into an at least single-pole switching device. The access contact of the plug adapter is designed in the form of a contact spring equipped with a free end in a clamping chamber. It is a standard push-in terminal. The access contact is accessible via an access contact housing opening which--in the plugged-in position of the plug-in adapter--is parallel to the insertion opening of the connection contact of the switching device. The free end of the contact spring is placed against the busbar with elastic pretension. Furthermore, there is a clamping device for clamping a supply line wire to the contact spring in such a way that the clamping device can be actuated (manually) via an actuating clip, the actuating clip acting on a hold-down device so that the free contact spring arm can be moved away from the busbar of the plug-in adapter. Furthermore, the plug-in adapter has a housing recess on its underside facing the switching device, the span of which corresponds to the distance between the combination plug-in opening of the switching device and the upper edge of the switching device access side. Contact springs in push-in terminals have a relatively strong restoring or spring force. With the use of the operating bar, the lever effect of the operating bar is used so that manual operation is possible with little effort.

the DE 10 2008 052 626 A1 discloses a terminal with an insulating housing, at least one spring-cage terminal, which is formed from a bent spring steel sheet clamping spring with a bearing on a busbar piece system legs, a spring bow and a resiliently movable Has clamping legs and is accommodated in the insulating material housing for clamping a conductor that can be inserted through a conductor insertion opening in the insulating material conductor, and with at least one actuating element which is assigned to a spring-loaded terminal connection in each case. The actuating element has a bracket that encompasses the clamping spring on both sides and rests against the contact leg or the adjacent busbar piece, and an actuating lever that is connected to the bracket and shaped in such a way that the actuating lever lies opposite to where the bracket rests on the clamping spring and the clamping spring when the actuating lever is pivoted in an open position for opening the spring-loaded terminal connection is actuated.

More conductor terminals are, for example, from EP 2 096 714 A1 and the DE 87 04 494 U1 known.

The object on which the present invention is based is to provide an improved, more user-friendly and more compact conductor connection terminal.

This object is solved by a conductor terminal having the features of claim 1 of the present invention. Advantageous embodiments are described in the claims dependent on claim 1.

More precisely, the object on which the present invention is based is achieved by a conductor connection terminal, which is characterized in that the pivoting lever has a feed-through opening arranged between the pusher element and the axle strut, through which a Head can be passed, and that a receiving opening of the pivoting lever is formed between an actuating handle of the pivoting lever and the pusher element, through which the holding leg and the clamping leg of the clamping spring are passed.

The conductor connection terminal according to the invention offers the advantage that it is particularly space-saving and consequently has a compact design, while also ensuring that electrical conductors with an enlarged line cross section can also be clamped.

The electrical conductor to be clamped can be brought into direct contact with the contacting section of the current bar when the conductor is inserted into the housing via the insertion opening. A build-up of tension in the clamping spring is to be understood in particular as a build-up of tension in the flexible joint of the clamping spring. The angle between the holding leg and the clamping leg changes due to a build-up of tension in the flexible joint of the clamping spring. The retaining leg of the clamping spring is used to hold the clamping spring within the housing.

The closed position of the pivoting lever is associated with the clamping position of the clamping leg, and the open position of the pivoting lever is associated with the release position of the clamping leg.

The conductor connection terminal is preferably designed in such a way that a contacting plane defined by the contacting section is arranged between the pusher element and the axle strut of the pivoted lever.

A correspondingly designed conductor connection clamp offers the advantage that electrical conductors with an even larger conductor cross section can also be clamped. Because of the positioning of the contacting section of the current bar between the pusher element and the axle strut, when the pivoted lever is transferred from the closed position to the open position, the clamping leg is pushed away from the contacting section by an increased stroke, so that even conductors with a large cable cross-section can be placed between the clamping legs of the clamping spring and can be inserted into the contacting section of the current bar.

In the case of the correspondingly designed conductor connection terminal, the contacting section and thus also the contacting plane are arranged below the pusher element and above the axle strut.

The conductor connection terminal is preferably designed in such a way that when the pivoted lever is in the open position, the pusher element is positioned with respect to the axle strut in such a way that the pivoted lever is pressed in the direction of its open position when force is applied to the pusher element by means of the clamping leg in the release position.

Appropriate design of the conductor connection terminal results in self-locking of the pivoted lever when the pivoted lever has been pivoted into its open position. In the open position of the pivoted lever, this is not transferred to its closed position by the exertion of force on the pusher element by means of the clamping leg of the clamping spring.

In the side view of the conductor connection terminal, the swivel lever is in the open position the pusher element arranged behind the axle strut. A horizontal distance between the pusher element and the insertion opening is then greater than a horizontal distance between the axle strut and the insertion opening. When the pivoted lever is pivoted from the closed position into its open position, the pusher element executes a partial circular path around the pivot axis/rotational axis defined by the axle strut, with the pusher element being pivoted beyond a dead center of the circular path when the pivoted lever is pivoted in its entirety into its open position. In the dead center, the clamping leg is at a maximum distance from the contacting area of the current bar. Before the dead center is reached, the distance between the pusher element and the contact area is smaller. When the dead center is exceeded, the distance between the pusher element and the contacting area decreases again.

As a result, self-locking is implemented, since the clamping leg located in the release position does not remain in the release position without manual folding/pivoting of the pivoted lever into its closed position.

The conductor connection terminal is preferably designed in such a way that the pusher element is designed as a compression strut, which runs essentially parallel and offset to the axle strut. The correspondingly designed conductor connection terminal can be designed to be particularly material-saving. Furthermore, the resulting free spaces in the conductor connection terminal can be used to accommodate the clamping spring, for example.

More preferably, the conductor terminal is designed such that a receiving opening of the pivoting lever is formed between an actuating handle of the pivoting lever and the pusher element, through which the holding leg and the clamping leg of the clamping spring are guided. The correspondingly designed conductor connection terminal is very space-saving and consequently has a compact design.

According to the invention, the conductor connection terminal is designed such that the pivoting lever has a feed-through opening arranged between the pusher element and the axle strut, through which a conductor inserted through the insertion opening into the housing and to be contacted with the current bar can be passed. This feature also results in a compact design of the conductor connection terminal.

More preferably, the conductor connection terminal is designed in such a way that the clamping spring is designed to be elastic at least in sections and an angle enclosed by the holding leg and clamping leg can be changed, so that when the clamping leg is in the clamping position, a conductor can be inserted into the housing via the insertion opening and with elastic deformation of the clamping spring between the clamping leg and the contacting section of the current bar can be positioned.

The angle enclosed by the pressure leg and the clamping leg is consequently changed, in particular reduced, by inserting a conductor into the insertion opening. For example, the bending joint of the clamping spring can be designed to be elastic. However, the entire clamping spring can also be designed to be elastic, in particular if the clamping spring is made of spring steel.

A correspondingly designed conductor connection terminal offers the advantage that, despite the pivoted lever being in the closed position and consequently the clamping spring being in the clamping position, a conductor can still be inserted into the housing via the insertion opening and connected to the current bar, which can also generally be referred to as a connecting device. it also being ensured that the conductor is subjected to a force by means of the clamping spring on the current bar, more precisely on the contacting section of the current bar, and is thus clamped. The handling of the correspondingly designed conductor connection terminal is therefore considerably improved, since the pivoting lever does not necessarily have to be pivoted into its release position in order to contact an electrical conductor with the conductor connection terminal.

More preferably, the conductor connection terminal is designed in such a way that the contacting section of the current bar is designed as a clamping plate with which a conductor inserted into the housing via the insertion opening can be brought into contact, with the clamping leg being in the clamping position with the clamping plate at an angle of less than or equal to 90°.

Appropriate design of the conductor terminal and in particular the clamping spring allows a further simplified insertion of a conductor into the conductor terminal despite the pivoting lever being in the closed position and the corresponding clamping leg of the clamping spring being in the clamping position. Furthermore, a corresponding angular position of the clamping limb towards the clamping plate or towards the conductor inserted into the conductor terminal ensures that the clamping limb of the clamping spring counteracts an unintentional pulling out of the conductor in an improved manner, since the edge of the clamping limb of the clamping spring Pulling out the conductor from the housing digs into the conductor.

More preferably, the conductor connection terminal is designed in such a way that the housing has a bearing shell in which the axle strut of the pivoted lever is accommodated. This ensures a secure positioning of the pivoting lever in the housing and enables simple assembly of the correspondingly designed conductor connection terminal, since the axle strut only has to be inserted into the bearing shell provided for this purpose and possibly latched.

In the description that now follows, the same reference symbols denote the same components or the same features, so that a description of a component carried out with reference to one figure also applies to the other figures, so that a repeated description is avoided. Furthermore, individual features that have been described in connection with one embodiment can also be used separately in other embodiments.

1 shows a conductor terminal 1 according to the invention, which has a housing 100 which comprises a first part 110 and a second part 120 . Like in particular 2 As can be seen, the first part 110 and the second part 120 of the housing 100 can be connected to one another via a snap-in connection. For this purpose, the second part 120 of the housing 100 has holding tongues 122 which can engage in holding recesses 112 arranged in the first part 110 of the housing 100 so that the holding recesses 122 are engaged by the holding tongues 112 from behind.

In the exemplary embodiment shown, the housing 100 has three first insertion openings 123 and three second insertion openings 113 so that three pairs of electrical conductors can be connected to one another by means of the correspondingly designed conductor connection terminal 1 . However, the conductor connection terminal 1 can have any number of first insertion openings 123 and second insertion openings 113 in order to electrically connect a corresponding number of electrical conductor pairs to one another.

As in particular from the 3 and 4 As can be seen, a current conductor can be inserted into the second insertion opening 113 and clamped by a tulip contact 301 of the current bar 300 . For this purpose, the current bar 300 comprises two elastic conductor tongues running toward one another, which form the contact tulip 301 . A reliable electrical connection from a contact tongue inserted into the second insertion opening 113 to the current bar 300 is ensured by a corresponding structure. A conductor can be inserted into the conductor connection terminal 1 via the first insertion opening 123 and electrically connected to the current bar 300 in that a clamping spring 400 applies force to the electrical conductor inserted into the conductor connection terminal 1 via the first insertion opening 123 in the direction of the current bar 300.

A printed circuit board connection terminal (not shown) can also be implemented as a further embodiment. Here, instead of a contact tulip, soldering pins are led out of the insulating housing, which can be soldered to a printed circuit board. The soldering pins are connected to the current bar 300 in one piece.

The application of force to the conductor introduced via the first insertion opening 123 into the conductor connection terminal 1 by means of the clamping spring 400 is described with reference to FIG 3 and 4 explained, each showing a cross section of the conductor terminal 1. The connection of two electrical conductors to one another is explained as an example, it being noted that the conductor terminal 1 has a number of pivoted levers 200, clamping springs 400 and current bars 300 corresponding to the number of poles of the conductor terminal 1.

Based on the representations of 2 until 4 the internal structure of the conductor connection terminal 1 is described using the example of the connection of a pair of electrical conductors. The conductor terminal 1 has a pivoted lever 200, which can also be referred to as an actuating element 200, the pivoted lever 200 relative to the housing 100 between an in 3 shown open position and an in 4 shown closed position is pivotable. For this purpose, the pivoting lever 200 is in a guide recess 124 of the second part 120 of the housing ses 100 slidably and / or pivotally added.

The clamping spring 400 has a holding leg 401 and a clamping leg 403 connected to it via a flexible joint 404 . The clamping spring 400 also has a leg 402 in which an opening or window is arranged, so that the leg 402 can also be referred to as a window leg 402 . The end of the clamping leg protrudes through the window of the window leg 402 . The holding leg 401 and the clamping leg 403 run approximately parallel to one another in the area of the flexible joint 404 , the clamping leg 403 extending away from the flexible joint 404 and being bent in the direction of a clamping plate 302 of the current bar 300 .

The pivoted lever 200 has an actuating handle 201, which can also be referred to as a grip contour 201, and by means of which the pivoted lever 200 can be pivoted between the open position and the closed position. The pivoting lever 200 also has a pusher element 202 designed as a compression strut 202 and an axle strut 203 . The strut 202 and the axle strut 203 are substantially parallel to each other. In particular from the 3 and 4 it can be seen that a receiving opening 204 of the pivoting lever 200 is formed between the actuating handle 201 and the strut 202, through which the holding leg 401 and the clamping leg 403 are passed. Furthermore, the pivoting lever 200 has a feed-through opening 205 arranged between the compression strut 202 and the axle strut 203, through which a conductor inserted into the housing 100 via the insertion opening 123 and to be contacted with the current bar 300 can be passed. A bearing shell 121 is provided in the housing 100, in which the axle strut 203 is rotatably accommodated, so that the pivoting lever 200 is pivotably mounted with respect to the housing 100.

In 4 the conductor connection terminal 1 is shown with the pivoted lever 200 in the closed position. The pusher element 202 rests against the clamping leg 403 , the clamping leg 403 being in contact with the contacting section 302 of the current bar 300 embodied as a clamping plate 302 due to its bending. By pivoting the pivoting lever 200 in the in 3 shown open position of the conductor terminal, the clamping limb 403 is pushed away from the current bar 300 into its release position by means of the compression strut 202 with tension building up in the clamping spring 400, so that the clamping limb 403 is no longer connected to the clamping plate 302.

From the 3 and 4 it can be seen that a contacting plane 303 defined by the contacting section 302 or by the clamping plate 302 is arranged between the compression strut 202 and the axle strut 203 . Consequently, the contacting section 302 and thus also the contacting plane 303 are arranged below the compression strut 202 and above the axle strut 203 . Due to the positioning of the axle strut 203 below the clamping plate 302, when the pivoting lever 200 is pivoted, the strut 202 and consequently also the clamping leg 403 perform a large stroke and move correspondingly far away from the clamping plate 302, so that a large receiving space between the clamping plate 302 and the Clamping leg 403 is formed, whereby electrical conductors with a large conductor cross-section can be inserted into the correspondingly designed conductor terminal 1.

Also provided between the compression strut 202 and the axle strut 203 is a feed-through opening 205 of the pivoted lever 200 through which a conductor inserted through the insertion opening 123 into the housing 100 and to be contacted with the current bar 300 can be passed. The corresponding design of the pivoted lever 200 enables a compact design of the conductor connection terminal 1.

The clamping spring 400 is elastic since it is made of spring steel. Consequently, an angle enclosed by retaining leg 401 and clamping leg 403 can be changed, so that even when clamping leg 403 is in the clamping position, a conductor can be inserted into housing 100 via insertion opening 123 and with elastic deformation of clamping spring 400 between clamping leg 403 and clamping plate 302 can be inserted or inserted. This insertion of a conductor between the clamping leg 403 and the clamping plate 302 when the pivoted lever 200 is in the closed position is also promoted by the feature that when the clamping leg 403 is in the clamping position, it encloses an angle of less than 90° with the clamping plate 302, which is open to the insertion opening 123.

In particular from 3 It can be seen that in the open position of the pivoted lever 200, the strut 202 is positioned with respect to the axle strut 203 in such a way that force is applied to the strut 202 by means of the clamping leg 403 in the released position, pushing the pivoted lever 200 in the direction of its open position. When the pivoted lever 200 is in the open position, it is not transferred into its closed position by the application of force to the strut 202 by means of the clamping leg 403 . Out of the side sectional view of 3 results in that the strut 202 is arranged behind the axle strut 203, consequently a horizontal distance of the strut 202 to the insertion opening 123 is greater than a horizontal distance of the axle strut 203 to the insertion opening 123.

When pivoting the pivoting lever 200 from the in 4 shown closed position to the in 3 In the open position shown, the strut 202 executes a partial circular path around the pivot axis/rotational axis defined by the axle strut 203, the strut 202 being pivoted beyond a dead center of the circular path. At the dead center, the clamping leg 403 is at a maximum distance from the clamping plate 302 . When the pivoting lever 200 is pivoted past the dead center, the distance between the compression strut 202 and the contact area 302 becomes smaller again. Consequently, self-locking is realized when the pivoted lever 200 is in its open position, since the clamping leg 403 located in the released position does not remain in the released position without manual folding or pivoting of the pivoted lever 200 into its closed position.
