CONNECTION ARRANGEMENT, TERMINAL AND ELECTRONIC DEVICE

Description

[0001] The invention relates to a connection arrangement for connecting an electrical conductor, which has a current bar, a clamping spring which has a holding leg and a clamping leg, wherein the clamping leg can be transferred into a clamping position and into a release position, a conductor connection space formed between a section of the current bar and the clamping leg of the clamping spring, a displaceably arranged guide element which is in operative connection with the clamping leg of the clamping spring, wherein the clamping leg can be held in the release position by means of the guide element, and a pivotably mounted actuating element by means of which the guide element can be displaced to transfer the clamping leg of the clamping spring from the clamping position into the release position. The clamping spring is arranged between the section of the current bar and the actuating element.In addition, the guide element has a sliding surface along which the actuating element can be guided during a pivoting movement of the actuating element. The invention further relates to a connection terminal and an electronic device.

[0002] A corresponding connection arrangement is known from DE 10 2015 115 612 A1. Further connection arrangements are known, for example, from DE 19 67 288 U and DE 20 2019 101 246 U1.

[0003] Such connection arrangements usually have a clamping spring designed as a leg spring, which has a holding leg and a clamping leg, wherein a conductor inserted into the connection arrangement can be clamped against the current bar by means of the clamping leg of the clamping spring. If flexible conductors in particular are clamped, the clamping spring must be moved into a release position by means of an actuating element before the conductor is inserted and thus actuated in order to pivot the clamping spring or the clamping leg away from the current bar so that the conductor can be inserted into the space between the current bar and the clamping spring. Only with rigid and therefore stable conductors can the conductor apply sufficient force to the clamping spring or the clamping leg of the clamping spring to pivot the clamping leg away from the current bar without the user having to actuate the actuating element.With flexible conductors, the user must first pivot the clamping spring away from the current bar by pressing the actuating element so that the flexible conductor can be inserted. The actuating element typically presses against the clamping leg of the clamping spring to pivot the clamping leg away from the current bar and expose the conductor connection space.

[0004] The invention is based on the object of providing a connection arrangement as well as a connection terminal and an electronic device in which handling for a user when connecting conductors can be simplified.

[0005] The object is achieved according to the invention with the features of the independent claims. Expedient embodiments and advantageous further developments of the invention are specified in the subclaims.

[0006] The connection arrangement according to the invention is characterized in that the guide element has two longitudinal side walls and two end walls arranged at right angles to the two longitudinal side walls, wherein the sliding surface is arranged on one of the two end walls of the guide element, and wherein the two longitudinal side walls of the guide element are designed to be so long in the insertion direction of the conductor that the two longitudinal side walls delimit the conductor connection space on a first side and a second side opposite the first side.

[0007] The clamping spring is preferably designed as a leg spring, which has a holding leg and a clamping leg pivotable relative to the holding leg. By pivoting the clamping leg, it can be moved into a release position, in which the clamping leg is arranged at a distance from the current bar and a conductor to be connected can be inserted into or removed from a conductor connection space formed thereby between the current bar and the clamping leg, and into a clamping position, in which the clamping leg can bear against the current bar or the connected conductor to clamp the conductor against the current bar.The connection arrangement has a guide element, which is mounted in particular for horizontal displacement and which is preferably operatively connected to the clamping spring both in the release position and in the clamping position of the clamping leg of the clamping spring. This means that the clamping leg can follow the displacement movement and thus the position of the guide element due to the operative connection with the guide element. The guide element holds the clamping leg in the release position against its spring force by the guide element pressing against the clamping leg. The guide element can be designed as a slide element. The connection arrangement further has a pivotably mounted actuating element, by means of which the guide element can be displaced to transfer the clamping leg of the clamping spring from the clamping position into the release position.The actuating element is designed in such a way that, through a pivoting movement of the actuating element, the actuating element can apply a compressive force to the guide element in order to move the guide element against the spring force of the clamping leg of the clamping spring until the clamping leg reaches the release position. Through the sliding movement of the guide element, the guide element can apply a tensile force to the clamping leg of the clamping spring in order to transfer the clamping leg from the clamping position to the release position. The actuating element can preferably be pivoted in a direction which is oriented opposite to a pivoting direction of the clamping leg from the clamping position to the release position. If a pivoting movement of the actuating element occurs in a clockwise direction to transfer the clamping leg from the clamping position to the release position, the clamping leg is pivoted counterclockwise.If the actuating element is pivoted counterclockwise, the clamping leg is pivoted clockwise. The actuating element is positioned such that it just does not enter the conductor connection space, thus preventing interaction between the actuating element and the connected conductor. In contrast, the clamping spring, current bar, and actuating element are arranged such that the clamping spring is located between the section of the current bar against which a conductor to be connected is clamped and the actuating element. This can significantly simplify handling of the connection arrangement for a user when connecting an electrical conductor, since the actuating element is positioned away from the conductor connection space, and thus the insertion of a conductor is not impeded by actuation of the actuating element.The actuating element does not act directly on the clamping spring, but indirectly via the guide element.

[0008] According to the invention, the guide element has a sliding surface along which the actuating element can be guided during a pivoting movement of the guide element. The actuating element can rest against the sliding surface on the guide element, at least during a pivoting movement of the actuating element to transfer the clamping leg from the clamping position to the release position. The actuating element can slide along the guide element over the sliding surface during its pivoting movement, thereby exerting a compressive force on the guide element to displace the guide element.

[0009] The guide element has two longitudinal side walls and two end walls arranged at right angles to the two longitudinal side walls, wherein the sliding surface is arranged on one of the two end walls of the guide element. Due to the two longitudinal side walls and the two end walls arranged at right angles thereto, the guide element can have a rectangular configuration. The guide element can form a frame which can enclose or encompass, in particular, the section of the current bar against which the conductor can be clamped, and the clamping spring. The sliding surface is preferably oriented such that the sliding surface extends transversely to the two longitudinal side walls. The sliding surface can form an extension of the end wall on which the sliding surface is arranged. The sliding surface can form an inclined surface which can extend at an angle of inclination between 30° and 50° to the end wall on which the sliding surface is arranged.

[0010] The actuating element can have a rotational axis that can be moved along the sliding surface of the guide element during a pivoting movement of the actuating element. The pivoting movement of the actuating element can occur around the rotational axis, so that the pivot point of the actuating element lies on the rotational axis. This allows for force to be transmitted from the actuating element to the guide element directly at the pivot point of the actuating element, in order to move the guide element. This design enables a particularly compact, small-sized construction. The rotational axis can be designed in the form of an axle body.

[0011] The actuating element can have two arms arranged parallel to each other, wherein the rotation axis can extend between the two arms. The rotation axis is preferably oriented transversely to the longitudinal extension of the two arms. The rotation axis is preferably attached at a first end to a first of the two arms and at a second end to a second of the two arms.

[0012] The two arms can each have a guide surface at one end section, which can slide along an edge surface of the two longitudinal side walls of the guide element during a pivoting movement of the actuating element. The actuating element can be supported on the guide element via the guide surfaces of the arms, thus preventing the actuating element from tilting relative to the guide element during a pivoting movement of the actuating element. The guide surfaces can each be rounded.

[0013] To eliminate the need for an additional tool, such as a screwdriver, to operate the actuating element, the actuating element can have a handle portion for manual actuation of the actuating element. The handle portion can be formed on an end portion of the arms of the actuating element opposite the guide surfaces.

[0014] The sliding surface of the guide element can extend from an edge surface of one of the two end walls toward the actuating element. The sliding surface can thus form an extension of one of the two end walls toward the actuating element.

[0015] The guide element is preferably displaceable in such a way that a displacement movement of the guide element can occur transversely to the insertion direction of the conductor to be connected into the conductor connection space. This enables a particularly compact design, allowing the connection arrangement to be characterized by a reduced installation space.

[0016] In order to form an operative connection between the guide element and the clamping leg of the clamping spring, the guide element can have at least one spring contact edge against which the clamping leg can rest. The spring contact edge can be designed such that the clamping leg, or at least a portion of the clamping leg, can rest against the spring contact edge both in the release position and in the clamping position. The spring contact edge can be formed, for example, on a shoulder of the guide element.

[0017] To ensure consistent guidance of the guide element and the clamping leg of the clamping spring, two such spring contact edges can be formed on the guide element, so that the clamping leg can be guided on the guide element via two such spring contact edges. The two spring contact edges preferably extend parallel to each other on the guide element.

[0018] With such a configuration, it is possible for the clamping leg to have two sliding sections, each arranged to the side of a main section having a clamping edge, and for the guide element to have two spring contact edges arranged at a distance from one another, wherein a first sliding section can contact a first spring contact edge and a second sliding section can contact a second spring contact edge. The two sliding sections are preferably each shorter than the main section of the clamping leg. The main section and the two sliding sections preferably extend parallel to one another. The two sliding sections are preferably each curved, so that they can each form a sliding runner that can slide along a respective spring contact edge. The main section, on the other hand, is preferably straight.

[0019] According to the invention, the two longitudinal side walls of the guide element are designed to be so long in the insertion direction of the conductor that the two longitudinal side walls delimit the conductor connection space on a first side and a second side opposite the first side. The guide element can thus also guide the conductor to be connected when it is inserted into the conductor connection space. The two longitudinal side walls can prevent incorrect insertion of the conductor. The conductor connection space can thus be delimited on two of its sides by the guide element and on its other two sides by the current bar and by the clamping leg of the clamping spring. One of the two spring contact edges can be formed on each of the two longitudinal side walls.

[0020] To ensure stable mounting of the clamping spring, the clamping spring can be supported on the current bar via its retaining leg. For this purpose, the clamping spring can, for example, rest flatly against a portion of the current bar with a portion of the retaining leg. Furthermore, the retaining leg can also have an opening through which the portion of the current bar can pass, allowing the retaining leg to be suspended from the current bar. The portion of the current bar against which the retaining leg of the clamping spring is supported is preferably arranged opposite the portion of the current bar against which a conductor can be clamped. This portion of the current bar can form an end portion of the current bar.

[0021] The connection arrangement can further comprise a release element which can engage with the guide element when the clamping spring is in the release position. When the conductor to be connected is inserted into the conductor connection space, the release element can be actuated by the conductor in such a way that the release element is disengaged from the guide element and the guide element can be displaced by a spring force of the clamping leg in such a way that the clamping leg can be moved into the clamping position to clamp the conductor against the current bar. By providing a release element, a flexible conductor in particular can be connected and clamped against the current bar without actuating the actuating element. In order to be able to hold the guide element in the release position, the guide element can engage with the release element when the clamping leg of the clamping spring is in the release position.If the trigger element is engaged with the guide element, any displacement of the guide element is not possible or is stopped. By means of an operative connection or coupling of the trigger element with the guide element and of the guide element with the clamping leg of the clamping spring in the release position of the clamping leg, the clamping leg can be held in this release position without the aid of the actuating element, so that in particular a flexible conductor can be inserted into the conductor connection space thus created between the current bar and the clamping spring. The trigger element can have a pressure surface pointing in the direction of the conductor connection space, which pressure surface is aligned with an insertion area of ​​the conductor into the connection arrangement orcan be arranged flush with the conductor connection space, so that the conductor strikes the pressure surface of the trigger element when inserted into the connection arrangement, whereby a compressive force can be applied from the conductor to the trigger element. By applying a compressive force by means of the conductor to the pressure surface and thus to the trigger element, the trigger element can, for example, be set in a pivoting or tilting movement in the direction of insertion of the conductor, so that the trigger element can be pivoted or tilted away from the guide element in the direction of insertion of the conductor.By pivoting the release element, the release element can be brought out of engagement with the guide element so that the guide element can be moved freely again and thus the guide element can be moved solely by the spring force of the clamping leg without manual assistance in such a way that the clamping leg can be transferred from the release position into the clamping position.

[0022] This special mechanism allows for particularly easy connection of a flexible conductor simply by inserting the conductor, without the user having to operate additional elements, such as the actuating element, to release the clamping spring and move it from the release position to the clamping position. This simplifies handling of the connection arrangement and saves time when connecting a conductor. The release element preferably extends over the area between the section of the current bar against which a conductor can be clamped and the clamping spring, so that the release element can delimit the conductor connection space to one side.

[0023] In order to release the trigger element from the guide element by means of the conductor inserted into the conductor connection compartment, thus disengaging it from the guide element, the trigger element can be mounted so that it can be tilted relative to the guide element. The trigger element can thus be designed like a rocker. If the conductor to be connected is pressed against the trigger element, the trigger element can tilt in the direction of the conductor's insertion to disengage from the guide element and thus release the guide element, allowing it to be moved freely again.

[0024] In order to be able to form an engagement of the trigger element with the guide element in the release position of the clamping leg of the clamping spring, the trigger element can have at least one undercut, which can be locked with at least one locking lug of the guide element in the release position of the clamping leg of the clamping spring. This can form a locking connection between the guide element and the trigger element when the clamping leg of the clamping spring is in the release position. Preferably, the trigger element has two undercuts and the guide element preferably has two locking lugs, so that a double-acting locking connection can be formed between the guide element and the trigger element. If two undercuts are provided, these are preferably formed on two mutually parallel side surfaces of the trigger element.

[0025] The trigger element can be connected to the retaining leg of the clamping spring. The trigger element is preferably connected to the retaining leg in such a way that the trigger element can be pivoted relative to the retaining leg. The pivot axis is then preferably formed in the region of the connection of the trigger element to the retaining leg of the clamping spring. The connection between the retaining leg and the trigger element can preferably be designed such that the retaining leg is formed integrally with the trigger element. However, it is also possible for the trigger element to be an element or component formed separately from the clamping spring, the current bar, and the guide element.

[0026] The object of the invention is further achieved by means of a terminal block, in particular a series terminal block, which has at least one connection arrangement designed and further developed as described above. The terminal block can be arranged, for example, on a printed circuit board. If the terminal block is designed as a series terminal block, it can be arranged on a mounting rail.

[0027] It is also possible to provide a terminal arrangement which can have a plurality of terminals arranged in a row, each of which can have at least one connection arrangement designed and developed as described above.

[0028] Furthermore, a connector can also be provided which can have one or more of the connection arrangements described above, developed and further developed.

[0029] Furthermore, the object according to the invention can be achieved by means of an electronic device which can have at least one connection arrangement designed and further developed as described above and / or at least one connection terminal designed and further developed as described above.

[0030] The invention is explained in more detail below with reference to the accompanying drawings using a preferred embodiment.

[0031] It shows Fig. 1 a schematic representation of a terminal with a connection arrangement according to the invention with the clamping leg of the clamping spring in a clamping position, Fig. 2 a schematic representation of the in Fig. 1 shown terminal when the actuating element is actuated to transfer the clamping leg of the clamping spring from the clamping position to the release position, Fig. 3 a schematic representation of the Fig. 1 shown terminal with the clamping leg of the clamping spring in a release position, Fig. 4 a schematic sectional view of the Fig. 1 shown terminal, Fig. 5 a schematic sectional view of the in Fig. 2 shown terminal, and Fig. 6 a schematic sectional view of the Fig. 3 shown terminal.

[0032] In the Fig. 1 bis 6 a terminal 200 is shown with a housing 210, which can be made of an insulating material, wherein in the housing 210 a connection arrangement 100 for connecting a Fig. 1 and 4 shown conductor L is arranged or accommodated.

[0033] The connection arrangement 100 has a current bar 110 and a clamping spring 111 designed as a leg spring, as can be seen in particular in the sectional views of the Fig. 4 bis 6 can be seen. The clamping spring 111 has a holding leg 112 and a clamping leg 113. The holding leg 112 is held in a fixed position, whereas the clamping leg 113 is pivotable relative to the holding leg 112. By pivoting the clamping leg 113, it can be moved into a clamping position, as shown in Fig. 1 and 4 shown, and into a release position, as shown in particular in Fig. 3 and 6shown. In the clamping position, the clamping leg 113 presses against a section 114 of the current bar 110 or against a conductor inserted into the connection arrangement 100 in order to clamp and connect the conductor against the section 114 of the current bar 110. In the release position, the clamping leg 113 is positioned at a distance from the section 114 of the current bar 110 so that a conductor L can be inserted into the free space thus formed between the section 114 of the current bar 110 and the clamping leg 113.

[0034] The clamping spring 111 is supported on the current bar 110 via its holding leg 112.

[0035] Furthermore, the connection arrangement 100 has a guide element 115. The guide element 115 is mounted displaceably relative to the current bar 110, so that the guide element 115 can perform a horizontal displacement movement V.

[0036] By means of the guide element 115, the clamping leg 113 of the clamping spring 111 can be moved from the clamping position to the release position and held in the release position. For this purpose, the guide element 115 is operatively connected to the clamping leg 113 of the clamping spring 111.

[0037] In the embodiment shown here, the guide element 115 has two spring contact edges 116a, 116b arranged parallel to one another, against which the clamping leg 113 rests.

[0038] The clamping leg 113 has a main section 117, at the free end of which a clamping edge 118 is formed. Two sliding sections 119a, 119b are formed laterally of the main section 117, so that the main section 117 is arranged between the two sliding sections 119a, 119b. The two sliding sections 119a, 119b rest against the two spring contact edges 116a, 116b of the guide element 115, with the sliding section 119a resting against the spring contact edge 116a and the sliding section 119b resting against the spring contact edge 116b. The sliding sections 119a, 119b rest against the spring contact edges 116a, 116b both in the release position and in the clamping position of the clamping leg 113 of the clamping spring 111.

[0039] The sliding sections 119a, 119b have a shorter length than the main section 117. The sliding sections 119a, 119b are curved so that they form a skid shape, by means of which the sliding sections 119a, 119b can slide along the spring contact edges 116a, 116b when the clamping leg 113 is transferred into the release position and into the clamping position.

[0040] The two spring contact edges 116a, 116b are formed on opposite longitudinal side walls 120a, 120b of the guide element 115. The two longitudinal side walls 120a, 120b are arranged parallel to each other. The two longitudinal side walls 120a, 120b each have an upper edge 121a, 121b and an opposite lower edge 122a, 122b. The spring contact edges 116a, 116b each extend perpendicular to the upper edge 121a, 121b. Starting from the horizontally extending upper edge 121a, 121b, the spring contact edges 116a, 116b extend downwards in the direction of the horizontally extending lower edge 122a, 122b of the guide element 115. The lower edges 122a, 122b can slide parallel to a section 131 of the current bar 110 during a sliding movement of the guide element 115, which is aligned or oriented perpendicular to the section 114 of the current bar 110 to which a conductor L is clamped.

[0041] The current bar 110 and the clamping spring 111 are arranged between the two longitudinal side walls 120a, 120b of the guide element 115. The current bar 110 and the clamping spring 111 are enclosed by the guide element 115. The guide element 115 can thus form a frame that accommodates the current bar 110 and the clamping spring 111 in its interior.

[0042] The guide element 115 further has two end walls 123a, 123b, which are aligned parallel to each other. The two end walls 123a, 123b are arranged transversely to the two longitudinal side walls 120a, 120b of the guide element 115. The guide element 115 thus has a substantially rectangular cross-section.

[0043] Between the section 114 of the current bar 110 and the clamping leg 113, a conductor connection space 124 is formed, into which a conductor L to be connected can be inserted. The conductor connection space 124 is laterally covered or delimited by the two longitudinal side walls 120a, 120b of the guide element 115, so that the guide element 115 also forms a guide for the conductor L to be connected.

[0044] The conductor connection space 124 is aligned with a conductor insertion opening 211 formed in the housing 210, through which the conductor L to be connected can be inserted in the insertion direction E into the housing 210 of the connection terminal 200.

[0045] The connection arrangement 100 further comprises a trigger element 125. The trigger element 125 is arranged in alignment with the conductor insertion opening 211 and the conductor connection space 124. The trigger element 125 delimits the conductor connection space 124 at the bottom.

[0046] In the release position of the clamping leg 113 of the clamping spring 111, the trigger element 125 is in engagement with the guide element 115, as shown in particular in Fig. 3 can be seen, whereby the guide element 115 is held in its position and thereby also via the spring contact edges 116a, 116b and the sliding sections 119a, 119b of the clamping leg 113 is held in its position, so that an unintentional pivoting back of the clamping leg 113 from the release position into the clamping position can be prevented.

[0047] The trigger element 125 has two laterally arranged undercuts 126, which, in the release position of the clamping leg 113 of the clamping spring 111, each engage with a locking lug 127 of the guide element 115 to form a locking connection between the guide element 115 and the trigger element 125. A first locking lug 127 is formed on the longitudinal side wall 120a, and a second locking lug 127 is formed on the longitudinal side wall 120b. Due to the two undercuts 126, the trigger element 125 has a T-shape.

[0048] In the clamping position, the release element 125 is disengaged from the guide element 115, as shown in Fig. 1 can be seen, so that the guide element 115 is freely movable.

[0049] The trigger element 125 is mounted so as to be tiltable relative to the guide element 115.

[0050] When inserting a conductor L to be connected along the insertion direction E via the conductor insertion opening 211 into the conductor connection space 124, the conductor L strikes the release element 125, whereby the release element 125 tilts relative to the guide element 115 and thereby disengages from the guide element 115, so that the guide element 115 is freely displaceable again and thus the guide element 115 can be displaced solely by the spring force of the clamping leg 113 without manual assistance in such a way that the clamping leg 113 can be transferred from the release position into the clamping position.

[0051] The trigger element 125 has a pressure surface 128 pointing in the direction of the conductor connection space 124, which is arranged in alignment with the conductor insertion opening 211 or in alignment with the conductor connection space 124, so that the conductor L abuts the pressure surface 128 of the trigger element 125 upon insertion into the connection arrangement 100, whereby a compressive force is applied from the conductor L to the trigger element 125. By applying a compressive force by means of the conductor L to the pressure surface 128 and thus to the trigger element 125, the trigger element 125 can be set in a pivoting or tilting movement in the direction of insertion E of the conductor L, so that the trigger element 125 can be pivoted or tilted away from the guide element 115 in the insertion direction E of the conductor L.

[0052] The trigger element 125 is in the embodiment shown here, as in particular in Fig. 5 und 6 As can be seen, it is connected to the retaining leg 112 of the clamping spring 111. The trigger element 125 is connected in such a way that the trigger element 125 is pivotable relative to the retaining leg 112, which remains in a fixed position. The pivot axis can be formed in the region where the trigger element 125 is connected to the retaining leg 112.

[0053] The displacement movement V of the guide element 115, when it is disengaged from the trigger element 125, occurs in a direction which is oriented transversely to the insertion direction E of the conductor L to be connected into the conductor connection space 124.

[0054] In order to move the clamping leg 113 back from the clamping position to the release position against its spring force by means of the guide element 115, the connection arrangement 100 has an actuating element 129. The actuating element 129 is pivotally mounted according to the arrow S. The actuating element 129 is pivotable on an outer side of the housing 210 of the connection terminal 200.

[0055] The actuating element 129 is designed in the form of a pivoting lever. The actuating element 129 extends in length over more than two-thirds the height of the housing 210 of the terminal 200.

[0056] The actuating element 129 has two arms 132a, 132b running parallel to each other. The two arms 132a, 132b extend the length of the actuating element 129. A rotational axis 133 in the form of an axle body is arranged between the two arms 132a, 132b. The rotational axis 133 extends transversely to the longitudinal extent of the two arms 132a, 132b.

[0057] The guide element 115 has a sliding surface 130 in the form of an inclined surface, along which the actuating element 129 can be guided. In the embodiment shown here, the sliding surface 130 is formed on the end wall 123b of the guide element 115. The sliding surface 130 extends from the end wall 123b in the direction of the actuating element 129. Due to its design as an inclined surface, the sliding surface 130 is arranged at an angle such that the sliding surface 130 extends here at an angle of between 130° and 160° to the end wall 123b of the guide element 115.

[0058] Alternatively, it would also be possible for the sliding surface 130 to be arranged at a distance from the end wall 123b between the two longitudinal side walls 120a, 120b, so that the sliding surface 130 is directly connected to the longitudinal side walls 120a, 120b.

[0059] The rotation axis 133 forms the pivot point around which the actuating element 129 can be pivoted along the pivoting direction S. The rotation axis 133 is in operative connection with the sliding surface 130 of the guide element 115 upon actuation of the actuating element 129, in that during a pivoting movement of the actuating element 129 to transfer the clamping leg 113 from the clamping position into the release position, the rotation axis 133 can slide along the sliding surface 130 of the guide element 115, as shown in particular in Fig. 5 can be seen. As the rotational axis 133 slides along the sliding surface 130, the actuating element 129 applies a compressive force to the sliding surface 130 and thus to the guide element 115, whereby the guide element 115 is displaced horizontally by a displacement movement V.

[0060] By means of the actuating element 129, the guide element 115 can be displaced such that the clamping leg 113 of the clamping spring 111 resting against the guide element 115 can be moved from the clamping position into the release position. Upon actuation of the actuating element 129 in the pivoting direction S, the actuating element 129 can be pivoted downward such that it applies a compressive force to the guide element 115 via the rotation axis 133 in order to displace the guide element 115 against the spring force of the clamping leg 113 of the clamping spring 115 such that when the release position of the clamping leg 113 is reached, the guide element 115 can engage with the release element 125. This displacement movement V of the guide element 115 pivots the clamping leg 113 from the clamping position into the release position.

[0061] If the clamping leg 113 is in the release position and the guide element 115 is locked with the release element 125, the actuating element 129 can be pivoted back into its initial position, as shown in Fig. 3 and 6 can be seen. By means of the guide element 115, the clamping leg 113 remains in its release position without the aid of the actuating element 129. In this release position, the rotational axis 133 of the actuating element 129 is positioned away from the sliding surface 130. Only when the trigger element 125 is actuated by means of a conductor L and thus the locking between the trigger element 125 and the guide element 115 is released, whereby the guide element 115 is displaced by the force of the clamping leg 113 so that it can reach the clamping position, does the rotational axis 133 of the actuating element 129 again rest on the sliding surface 130 of the guide element 115, as for example in Fig. 1 and 4 is shown.

[0062] The two arms 132a, 132b each have a guide surface 134a, 134b at one of their end sections, which can slide along an edge surface 135a, 135b of the two longitudinal side walls 120a, 120 of the guide element 115 during a pivoting movement of the actuating element 129. The edge surfaces 135a, 135b are each formed at a right angle to the spring contact edges 116a, 116b. The edge surfaces 135a, 135b extend parallel to the upper edge 121a, 121b, in that the edge surfaces 135a, 135b are arranged at a height offset from the respective upper edge 121a, 121b. The actuating element 129 can roll on the guide element 115, in particular on the edge surfaces 135a, 135b of the guide element 115, via the guide surfaces 134a, 134b.

[0063] At an end portion of the arms 132a, 132b opposite the guide surfaces 134a, 134b, a handle portion 136 is formed, via which the actuating element 129 can be manually actuated.

[0064] Between the two arms 132a, 132b, the actuating element 129 has a free space 137 through which in the initial position, as shown in Fig. 1 , 3 , 4 and 6 shown, a part 138 of the housing 210 of the terminal assembly 200 protrudes.

[0065] The actuating element 129 is arranged adjacent to the retaining leg 112 of the clamping spring 111. The actuating element 129 is thus arranged behind the clamping spring 111. The clamping spring 111 is arranged between the section 114 of the current bar 110 and the actuating element 129. List of reference symbols
