Description

The present invention relates to a conductor connection terminal.

Conductor connection terminals are known from the prior art, by means of which an electrical conductor can be electrically connected reversibly to an electrical contact.

So describes the DE 10 2017 106 720 A1 a conductor connection terminal with a housing with a conductor receiving space for receiving an electrical conductor, accessible via a conductor insertion opening. A current bar is arranged in the conductor receiving space for contacting a conductor inserted into the conductor receiving space via the conductor insertion opening. Furthermore, a clamping spring with a spring clamping leg is arranged in the housing, the clamping spring being actuatable between a release position and a clamping position. In the release position, an electrical conductor can be inserted and / or removed from the conductor receiving space, and in the clamping position the spring clamp leg loads a conductor introduced into the conductor receiving space in the direction of the current bar. Finally, the conductor connection terminal comprises according to DE 10 2017 106 720 A1 another actuating element which can be displaced between a clamping position and a release position. The actuating element is operatively connected to the clamping spring in such a way that when the actuating element is transferred from its clamping position to its release position, the spring clamping leg is subjected to force by the actuating element and the clamping spring is transferred from its clamping position to its release position. The ones in the DE 10 2017 106 720 A1 The conductor connection terminal described thus ensures that an inserted electrical conductor is clamped or released by the actuation element being able to be displaced along an actuation direction, this actuation direction being received in the conductor parallel to the direction in which the electrical conductor is inserted.

Also from the DE 10 2007 050 683 A1 a similar conductor connection terminal is known, the conductor insertion direction being essentially perpendicular to the actuation direction.

In general, with conductor connection terminals, during the introduction of electrical conductors into the conductor receiving space, the problem can arise that an electrical conductor is "misplaced". Such a “conductor mishandling” is to be understood as meaning that the electrical conductor actually to be routed along the conductor insertion direction in the direction of the current bar leaves this intended conductor insertion direction laterally when it is inserted and is led out of the conductor receiving space laterally. As a result, the electrical conductor does not assume its actually intended position in the conductor receiving space. This is problematic in particular in the case of conductor connection terminals with housings that include an open side wall. The risk of a wire mismatch has a negative effect on the operational safety of the wire connection terminals, since safe contact between the electrical conductor and the current bar is not continuously guaranteed.

With a conductor connection terminal according to the DE 10 2007 050 683 A1 In the illustrated embodiment, a conductor mismatch is less of a problem. Thus, when an electrical conductor is pushed into the conductor receiving space, the spring clamping leg of the clamping spring is first pressed down by the inserted conductor. Coupled with this closing movement of the spring clamp leg is a downward movement of the actuating element along the actuating direction. As a result of this downward movement of the actuating element, a side wall of the actuating element permanently counteracts a lateral deflection of the electrical conductor or a stepping out of the conductor from the conductor receiving space.

The coupling of the closing of the clamping spring with the downward movement of the actuating element takes place according to FIG DE 10 2007 050 683 A1 but in an expensive way. For example, extra guide slots are provided on the actuating elements or actuating pushbuttons, into which guide sections specially provided on the clamping spring must be hooked. This elaborate design is associated with increased production costs, since both the actuating element and the clamping spring must be equipped with a special, mutually coordinated geometry for hanging the guide sections into the guide slots. Furthermore, the assembly is complex due to the process of hanging the guide sections in the guide slots.

The present invention is therefore based on the object of providing a conductor connection terminal which ensures increased operational reliability and at the same time represents an inexpensive system both in terms of manufacturing costs and in terms of assembly effort. In particular, it is desirable that the risk of a conductor misplacing is avoided.

This object is achieved by a conductor connection terminal with the features of claim 1. Advantageous embodiments of the conductor connection terminal are described in the dependent claims.

More precisely, the object on which the present invention is based is achieved by a conductor connection terminal, comprising a housing with a conductor receiving space accessible via a conductor insertion opening for receiving an electrical conductor, the electrical conductor being insertable into the conductor receiving space in a conductor insertion direction. Furthermore, the conductor connection terminal comprises a current bar arranged in the conductor receiving space for contacting a conductor introduced into the conductor receiving space via the conductor insertion opening. Furthermore, the conductor connection terminal comprises a clamping spring arranged in the housing with a spring clamping leg, wherein the clamping spring can be actuated between a release position and a clamping position, wherein at least in the release position an electrical conductor can be inserted and / or removed from the conductor receiving space, and in the clamping position the Spring clamp legs acted upon a conductor introduced into the conductor receiving space in the direction of the current bar. In addition, the conductor connection terminal comprises an actuation element which can be displaced along an actuation direction between a clamping position and a release position, the actuation element being in operative connection with the clamping spring in such a way that, when the actuation element is transferred from its clamping position to its release position, the spring clamping leg is actuated by the actuation element force is applied and the clamping spring is transferred from its clamping position to its release position. Finally, the conductor connection terminal according to the invention is characterized in that the actuating element has at least one first flank section on its end seen in the actuating direction and at least one first driver element on the first flank section. In this case, the first flank section, viewed in the actuation direction, extends laterally past the spring clamp leg to below an underside of the spring clamp leg. In addition, the first driver element protrudes from an inner side of the first flank section facing the spring clamp limb in the direction of the spring clamp limb and engages behind the spring clamp limb at least in the clamping position of the actuating element.

An operationally reliable and at the same time inexpensive system can be achieved by means of the conductor connection terminal according to the invention. The closing movement of the clamping spring, i.e. Transferring the clamping spring from its clamping position towards its release position is no longer exclusively coupled with the movement of the actuating element in that a displacement of the actuating element in the direction of actuation causes the clamping spring or the spring clamping leg to close. Rather, a coupling of the movement of the clamping spring and the actuating element also takes place in that closing the spring clamping leg or the clamping spring also causes the actuating element to be pulled down in the actuating direction. This takes place in that the spring clamping leg takes the actuating element with it via the first driver element of the actuating element and pulls it down. A driving force is brought about by the spring clamp leg on the first driver element in the direction of the actuation direction and thus the actuation element is also displaced along the actuation direction.

In this way, by inserting an electrical conductor into the conductor connection terminal, even if the clamping spring is in its clamping position and the actuating element is in its clamping position, not only a movement of the clamping spring in the direction of its release position, but also of the actuation element in its direction Release position are effected. Moving the actuating element in the direction of actuation can even go so far that the actuating element is completely moved into its release position by being carried along by the first driver element and thus also the clamping spring is completely moved into its release position.

The first flank section of the actuating element and, if necessary, also at least one side wall of the actuating element thus permanently represent a lateral flank for the conductor receiving space of the housing, also for housings of conductor connection terminals with open side walls. In this way, a conductor mismatch is avoided, since a conductor introduced into the conductor receiving space cannot be led out laterally from the conductor receiving space and thus cannot be misplaced. This is avoided in that the flank, that is to say the flank section or the side wall of the actuating element, blocks this outlet for the electrical conductor. The conductor mismatch is therefore no longer only prevented when a conductor is inserted into an actuating element that has already been moved into the release position, but rather now also when a conductor is inserted when the actuating element is still in its clamped position. Because when a conductor is inserted into the conductor receiving space, the actuating element, which is still in the clamping position, is also displaced via its driver element in the direction of actuation, whereby the flank of the actuating element closes the lateral exit from the conductor receiving space. In this way, an operationally reliable conductor connection terminal is achieved, in which a conductor mismatch is reliably prevented.

This also does not require any complex design solutions, as is the case with the prior art. There are no guide slots on the Actuating element is provided and it is therefore not necessary to hang the spring clamp leg into a guide slot. Furthermore, there is also no need for a special design of the clamping spring with regard to the geometry of the spring clamping leg. For example, no lateral projections are necessary on the spring clamping leg, but rather conventional clamping springs of simple geometries can be used in the conductor connection terminal according to the invention. As a result, an inexpensive conductor connection terminal is achieved that is easy to manufacture and, moreover, also easy to assemble.

The flank section or the inside of the flank section can therefore be designed to be uninterrupted, i.e. there is no need for a complex slit section, for example for suspending the spring clamping leg to couple the movement of the spring clamping leg with the movement of the actuating element.

The underside of the spring clamp leg means the side of the spring clamp leg facing away from the main part of the actuating element. In other words, the underside of the spring clamp leg faces away from the actuation element or is further away from the actuation element when viewed in the direction of actuation of the spring clamp leg.

The described engagement behind the spring clamp leg by the first driver element at least in the clamping position of the actuating element can also take place in positions of the actuating element that are shifted in the actuating direction, for example even in the release position of the actuating element.

The inside of the first flank section facing the spring clamp leg preferably runs along or parallel to the actuation direction. The first driver element extends from this inside of the first flank section in the direction of the spring clamping leg, preferably standing vertically on the inside of the first flank section.

The flank section or the inside of the flank section can simultaneously also assume a lateral guiding function for the actuating element. In particular in the case of housings comprising conductor connection terminals with an open side wall, there is a risk that the actuating element will tilt or slip out of the conductor receiving space. With the conductor connection terminal according to the invention, this can be prevented in that the inside of the flank section running laterally past the spring clip leg hits the side of the spring clip leg when the actuating element moves sideways, thus preventing sideways movement.

In the present case, an actuation or an actuation process of the actuation element means the process of transferring the actuation element from its clamping position to its release position. During an actuation process, the clamping spring is therefore moved from its clamping position into its release position in that the spring clamping leg or the clamping spring is closed and a possibly previously clamped electrical conductor is released.

The actuating element can also be referred to as an actuating lever or pusher. The actuating element can preferably have a handling section (or also referred to as operating section) and a pressure section (or also referred to as pusher section). The pressure section of the actuating element is preferably always in contact with the spring clamping leg of the clamping spring.

The actuating element is preferably set up in such a way that pressing the actuating element in the direction of actuation, i.e. applying force to the actuating element in the direction of the actuating direction in the form of exerting an actuating force, causes the actuating element to move in the direction of the clamping spring. As a result, the spring clamping leg or the clamping spring is closed, as a result of which the clamping spring is transferred from its clamping position into its release position. A flexible joint of the clamping spring is preferably deformed by moving its clamping position into its release position in such a way that a contact leg and the spring clamping leg of the clamping spring enclose a smaller angle with one another in their release position than in the clamping position of the clamping spring. The clamping spring therefore preferably has the spring clamping leg, which represents the movable leg of the clamping spring, and also a fixed, non-movable contact leg, and a flexible joint which connects the spring clamping leg and the contact leg to one another and around which the spring clamping leg is when opened or closed. Closing the clamping spring turns.

The actuation direction (or also called the pushing direction) can preferably be designed essentially perpendicular to the conductor insertion direction.

The housing is preferably formed from an electrically insulating material. The Housing can also be referred to as an insulating housing.

The electrical conductor can be inserted or pushed into the conductor receiving space in a conductor insertion direction via the conductor insertion opening. The electrical conductor can be easily plugged or pushed into the conductor receiving space when the clamping spring is in the release position and, for example, the actuating element is in the release position. This is because there is then no resistance to the insertion of an electrical conductor along the conductor insertion direction due to an open spring clamping leg of the clamping spring. Furthermore, the electrical conductor can also be inserted when the clamping spring is in the clamping position and, for example, the actuating element is in the clamping position. Then, however, the resistance that the opened spring clamping leg of the clamping spring offers to a movement of the electrical conductor along the conductor insertion direction into the conductor receiving space must be overcome when the conductor is pushed in. This requires an increased expenditure of force when inserting the electrical conductor in comparison to when the clamping spring is moved into the release position.

The current bar has electrically conductive areas at least in one contact area. The current bar is preferably formed from an electrically conductive material, for example a metal. The current bar is also electrically / galvanically connected to a further electrical contact device, for example an electrical contact pin and / or an electrical contact socket.

According to an advantageous embodiment, the actuating element has a second flank section on its end seen in the actuating direction on a side arranged opposite the first flank section and a second driver element on the second flank section. In this case, the second flank section, viewed in the actuation direction, extends laterally past the spring clamp leg to below the underside of the spring clamp leg. In addition, the second driver element protrudes from an inner side of the second flank section facing the spring clamping leg in the direction of the spring clamping leg and engages behind the spring clamping leg. As a result, an even more reliable conductor connection terminal is achieved, since the actuation element is no longer driven only by the first driver element when the spring clamp leg is closed, but is also supported by the second driver element. The inside of the second flank section facing the spring clamping leg can preferably run along or parallel to the actuation direction. The second driver element preferably extends from this inside of the second flank section in the direction of the spring clamping leg, standing perpendicularly on the inside of the second flank section. The properties described above with regard to the first flank section and the first driver element can also be transferred to the second flank section or the second driver element.

According to a further advantageous embodiment of the conductor connection terminal, the first driver element, preferably also the second driver element, can also engage behind the spring clamping leg in positions between the clamping position and the release position of the actuating element. In this case, the driver element or the driver elements can engage behind the spring clamp leg also in the release position of the actuating element. Alternatively, however, the actuating element can also be shifted so far in its release position in the actuating direction that the driver element or the driver elements no longer engage behind or engage behind the spring clamp leg in this release position. In other words, the actuating element is then shifted into its release position so far in the actuating direction that the first or possibly also the second driver element no longer engages behind or engages behind the spring clamping leg.

According to a further advantageous embodiment of the conductor connection terminal, the first driver element, preferably additionally also the second driver element, can slide along the underside of the spring clamping leg when the clamping spring is transferred from its clamping position to its release position. This sliding along the underside ensures that the first and second driver elements are permanently in contact with the underside of the spring clamping leg. This provides an even more reliable conductor connection terminal, since regardless of the starting position of the clamping spring, the actuating element is carried along via the first or second driver element when the spring clamp limb is closed by the permanent contact between the underside of the spring clamp limb and the driver element.

According to an advantageous embodiment, the actuating element can have at least one first actuating arm, the first flank section then extending on the first actuating arm in the actuating direction.

More preferably, the actuating element can furthermore have a second actuating arm, a free space being provided between the first actuating arm and the second actuating arm. The second flank section can then preferably extend in the actuating direction following the second actuating arm.

In this case, an electrical conductor introduced into the conductor receiving space can be arranged in the free space between the two actuating arms. This achieves a particularly compact embodiment of a conductor connection terminal.

The actuation arms preferably extend parallel to or along the actuation direction. The first actuating arm or also the second actuating arm can represent the pressure section (also referred to as the pusher section) of the actuating element and thus ensure that the clamping spring is actuated, that is, the spring clamping leg is closed.

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

In 1 is a conductor connection terminal according to the invention 1 shown. The conductor connection terminal 1 has a housing 10 which is formed from an electrically insulating material or at least has electrically insulating material. The case 10 has a conductor insertion opening 11 on over which a ladder receiving room 12 of the housing 10 is accessible. An electrical conductor L. is via the conductor entry opening 11 into the ladder reception room 12 insertable by the electrical conductor L. in a conductor insertion direction R. into the ladder reception room 12 is introduced or pushed in.

The conductor connection terminal 1 also has one in the conductor receiving space 12 arranged current bar 20th on, the one for contacting a conductor insertion opening 11 into the ladder reception room 12 imported electrical conductor L. is trained. The current bar 20th is made of an electrically conductive material, for example a sheet steel. The current bar 20th is also electrically connected to a further electrical contact device, for example an electrical contact pin and / or an electrical contact socket, the further electrical contact device not being shown in the figures.

In the case 10 is also a clamping spring 30th arranged, which has a contact leg 31 and a spring clamp leg 32 having, wherein the contact leg 31 and the spring clamp leg 32 via a flexible joint 33 are connected. The clamping spring 30th can be done by changing the position of the movable spring clamp leg 32 take different positions. So can the clamp spring 30th in the in 2A and 2C clamping position shown or in the in 1 as in 2 B Released position shown are brought.

In other words is the clamp spring 30th between their clamping position and their Release position can be activated. An actuation process therefore describes the process, like the clamping spring 30th from their clamping position ( 2A , 2C , 3A , 3B) in their release position ( 1 , 2 B) is brought.

The described transition of the clamping spring 30th from its clamping position to its release position is actuated by actuating an actuating element, for example manually or by means of a tool 40 realized. The actuating element is thereby 40 along an actuation direction B. moved, i.e. the actuating element 40 is pressed down. The actuator moves from the in 2A or. 2C or 3A or. 3B clamping position shown in 1 or. 2 B release position shown. During this transfer from its clamping position to its release position, the actuating element presses 40 on the spring clamp leg 32 the clamping spring and thus closes the clamping spring 30th , making the clamping spring 30th is brought from its clamping position to its release position. The spring clamp leg closes 32 with the contact leg 31 a larger angle in the clamping position than in the release position. In other words, the actuator exercises 40 during an actuation process, an actuation force in the direction of the spring clamp leg 32 the clamping spring 30th and thus closes the clamping spring 30th .

The movement of the clamp spring 30th , in particular the spring clamp leg 32 , is therefore with the movement of the actuator 40 coupled. This coupling is designed in such a way that the actuating element is pressed down 40 in the direction of actuation B. also a shifting or rotating of the spring clamp leg 32 in the direction of actuation B. , so a closing of the clamping spring 30th , causes.

How further from 1 becomes apparent, the actuating element 40 a first flank section 41 on. The first flank section 41 is on the one in the direction of actuation B. seen end of the actuator 40 intended. This first flank section 41 provides a kind of side flank for the conductor receiving space 12 represents. This takes over the first flank section 41 also a management function for the electrical conductor L. . A so-called conductor mismatch is avoided by the fact that the in the conductor receiving space 12 electrical conductors to be introduced L. not laterally out of the conductor receiving space when inserting 12 can emerge as the first flank section 41 such a leak is blocked. This is particularly advantageous for conductor connection terminals 1 comprising a housing 10 with an open side wall.

The first flank section also takes over 41 yet another lateral guiding function, namely for the actuating element 40 itself. This is how the first flank section extends 41 in actuation direction B. seen from the side of the spring clamp leg 32 past to under a bottom 34 of the spring clamp leg 32 (see 2A , 2 B and 2C ). This avoids that the actuating element 40 , for example during an actuation process, so when moving in the direction of the actuation direction B. , to the side of the first flank section 41 out in the direction of the spring clamp leg 32 could be pivoted. Because such a sideways movement of the actuating element 40 is by bumping against the spring clamp leg 32 prevented. This is the first flank section 41 executed continuously, that is, there are no slot sections or the like.

The actuator 40 can be set or determined both in its clamping position and in its release position. Accordingly, there is no permanent application of force or actuation of the actuating element 40 in the direction of actuation B. necessary to the actuator 40 for example to let it remain in its release position.

The coupling of the movement of the actuating element described above 40 and the spring clamp leg 32 does not only take place in such a way that from a movement of the actuating element 40 in the direction of actuation B. a closing of the spring clamp leg 32 results. Rather, the movements of the spring clamp leg are 32 and the actuator 40 also coupled such that pivoting of the spring clamp leg 32 down in the direction of actuation B. also to a displacement of the actuating element 40 in the direction of actuation B. leads. This is particularly beneficial when using an electrical conductor L. into the ladder reception room 12 should be introduced without the clamping spring 30th previously in their release position ( 2 B) or the actuator 40 in its release position ( 2 B) has been moved. So can an electrical conductor L. also via the conductor entry opening 11 the conductor connection terminal 1 be fed when the clamp spring 30th is still in the clamping position and the actuating element 40 still in its clamping position, i.e. in a state as in 2A shown. Then the electrical conductor is inserted L. for bumping against the spring clamp leg 32 whereupon this around the flexure joint 33 in the direction of actuation B. is pivoted. This pivoting of the spring clamp leg 32 down then also ensures a coupled movement of the actuating element 40 down in the direction of actuation B. .

The coupling of this movement is illustrated in 3A as in 3B clear. So is the actuator 40 from the in 3A shown clamping position down in the direction of actuation B. in the in 3B position shown moved by the spring clamp leg 32 a first driver element 45 in the direction of actuation B. acted upon by force and thus the first driver element 45 and thereby finally the entire actuating element 40 moves down.

This is the first driver element 45 on the first flank section 41 intended. The first driver element is specifically in place 45 from one of the spring clamp legs 32 facing inside 47 of the first flank section 41 in the direction of the spring clamp leg 32 and engages behind the spring clamp leg 32 . This grip behind the spring clamp leg 32 by the first driver element 45 from below takes place at least in the in 3A shown clamping position of the actuator 40 .

Furthermore, the first driver element 45 , as in 3B you can see the spring clamp leg 32 also in positions between the clamping position and in the release position of the actuating element 40 reach behind. In the release position, the actuating element 40 optionally so far down in the direction of actuation 40 be shifted that the first driver element 45 in this release position the spring clamp leg 32 no longer engages behind.

The protrusion of the first driver element 45 from the inside 47 of the first flank section 41 is better from the in 4A illustrated embodiment of an actuating element 40 evident. The first driver element is here 45 essentially perpendicular on the inside 47 of the first flank section 41 .

The one on the spring clamp leg 32 facing inside 47 of the first flank section 41 runs along or parallel to the direction of actuation B. .

Furthermore, the actuating element 40 at his in the direction of actuation B. seen end on one of the first flank section 41 the opposite side also has a second flank section 42 as from the further in 4B illustrated embodiment becomes apparent. The second flank section 42 extends in the direction of actuation B. seen from the side of the spring clamp leg 32 past to below the bottom 34 of the spring clamp leg 32 . In this case, on the second flank section 42 also a second driver element 46 be provided, the second driver element 46 from one of the spring clamp legs 32 facing inside of the second flank portion 42 in the direction of the spring clamp leg 32 protrudes and the spring clamp leg 32 engages behind.

The first driver element 45 , preferably also the second driver element 46 , slides or slide when transferring the clamping spring 30th from their clamping position to their release position on the underside 34 of the spring clamp leg 32 along, as can be seen from the two illustrations in 3A and 3B each with different positions of the clamping spring 30th as well as different contact points between the clamping spring 30th and the first driver element 45 becomes apparent. By sliding along the bottom 34 it is ensured that the first or second driver element 45 , 46 permanently in contact with the underside 34 of the spring clamp leg 32 stand.

How with the 4A and the 4B can also be seen, the actuating element 40 a first actuator arm 43 and a second actuator arm 44 exhibit. Between the first operating arm 43 and the second actuator arm 44 is still a free space 48 educated. Through this free space 48 prevents the in the ladder receiving space 12 electrical conductors to be introduced L. and the actuator 40 block each other. There is enough space for an electrical conductor to be inserted L. and at the same time a compact conductor connection terminal 1 , especially a compact actuator 40 , provided. The first flank section 41 extends to the first actuator arm 43 in the direction of actuation B. subsequently. If, as in the exemplary embodiment after 4B provided a second flank section 42 is provided, this second flank section extends 42 to the second actuating arm 44 then in the actuation direction B. .
