Description

TECHNICAL FIELD

[0001] The present application relates to a connection device for connecting electrical conductors. The present application also relates to a connection terminal and to an electronic device. BACKGROUND

[0002] Such connection devices usually have a clamping spring designed as a torsion spring, which has a holding leg and a clamping leg, wherein a conductor inserted into the connection device can be clamped on the current bar by means of the clamping leg of the clamping spring. If, in particular, a flexible conductor is to be clamped, the clamping spring must be moved into a release position and thus be manipulated by means of a manipulation element before the conductor is inserted, in order to pivot the clamping spring or the clamping leg away from the current bar, so that the conductor can be introduced into the intermediate space between the current bar and the clamping spring. Only in the case of a rigid and thus stable conductor, the conductor can exert sufficient force on 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 manipulate the manipulation element for this purpose. In the case of a flexible conductor, the user must first pivot the clamping spring away from the current bar by means of the manipulation element, so that the flexible conductor can be inserted. Here, the manipulation element is usually pressed against the clamping leg of the clamping spring in order to pivot the clamping leg away from the current bar and to release the conductor connection space. SUMMARY

[0003] The present application is based on the object of providing a connection device and a connection terminal and an electronic device, wherein the operation of the user when connecting a conductor can be simplified.

[0004] This object is achieved according to the application by the features of the independent claims. Advantageous design proposals and advantageous extensions of the application are given in the dependent claims.

[0005] The connection device according to the application has a current bar, a clamping spring with a holding leg and a clamping leg, wherein the clamping leg is movable into a clamping position and a release position, a conductor connection space formed between a section of the current bar and the clamping leg of the clamping spring, a movably 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 manipulation element, by means of which the guide element can be moved in order to move 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 manipulation element.

[0006] The clamping spring is preferably designed as a torsion spring (Schenkelfeder) having a holding leg and a clamping leg designed to be pivotable relative to the holding leg. By means of a pivoting movement of the clamping leg, it can be transferred into a release position in which the clamping leg is arranged at a distance from the current bar and the conductor to be connected can be inserted into or led out of a conductor connection space formed thereby between the current bar and the clamping leg, and it can be transferred into a clamping position in which the clamping leg can lie against the current bar or the connected conductor in order to clamp the conductor on the current bar. The connection device has a guide element which can be mounted in particular horizontally moveably, which is preferably in operative connection with the clamping spring both in the release position and in the clamping position of the clamping leg of the clamping spring, which means that the clamping leg follows the displacement movement of the guide element and thus its position by means of the operative connection with the guide element. By means of pressing the guide element against the clamping leg, the guide element holds it in the release position against the spring force of the clamping leg. The guide element can be designed as a sliding element. The connection device also has a handling element by means of which the guide element can be moved in order to transfer the clamping leg of the clamping spring from the clamping position into the release position. The handling element can preferably be designed to exert a pressure on the guide element in order to move it against the spring force of the clamping leg of the clamping spring until the clamping leg reaches the release position. In this release position, the clamping leg can be held indirectly by the handling element via the guide element. By means of the displacement movement of the guide element, it can exert a pulling force on the clamping leg of the clamping spring in order to transfer the clamping leg from the clamping position into the release position. The handling element is preferably moveable in a direction which is oriented transversely to the displacement movement direction of the guide element. The handling element can preferably be moved in a purely translatory manner. The movement direction of the handling element is preferably oriented parallel to the direction in which the conductor is introduced into the conductor connection space. The handling element is arranged such that it does not project into the conductor connection space, so that an interaction of the handling element with the connected conductor can be prevented. In contrast, the clamping spring, the current bar and the handling element are arranged in such a way that the clamping spring is arranged between a section of the current bar on which the conductor to be connected is clamped and the handling element. Thereby, the operation of the connection device by the user can be significantly simplified when connecting electrical conductors, since the handling element is positioned at a location which is remote from the conductor connection space and thus does not hinder the insertion of the conductor when handling the handling element.

[0007] The guide element can have a sliding surface along which the handling element can be guided. The handling element can lie plane against the guide element on the sliding surface. The handling element can slide along the guide element by means of the sliding surface and thereby transfer a pressure onto the guide element in order to move the guide element.

[0008] The guide element can have two longitudinal side walls and two end walls arranged perpendicular to the two longitudinal side walls, wherein the sliding surface can be arranged on one of the two end walls of the guide element. By means of 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 in particular surround or enclose the section of the clamping conductor of the current bar and the clamping spring. The sliding surface is preferably oriented in such a way 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.

[0009] The sliding surface can form a ramp which can interact with a ramp formed on the actuating element. If the sliding surface is designed as a ramp, it preferably has a gradient. The face of the actuating element which rests on the sliding surface is then also preferably designed as a ramp which is designed to be inclined with respect to the longitudinal extension of the actuating element which extends in the direction of movement of the actuating element. The gradient of the sliding surface and the gradient of the face of the actuating element can be formed at an angle of between 30° and 50° to the actuating direction of the actuating element. If the sliding surface and the face of the actuating element along which the actuating element slides are both designed as ramps, the vertical movement direction of the actuating element can be converted or transformed into a horizontal displacement movement of the guide element when the actuating element slides along the sliding surface.

[0010] The sliding surface can extend in the direction of the actuating element from an edge face of one of the two end walls. The sliding surface can thus form an extension of one of the two end walls in the direction of the actuating element.

[0011] The guide element is preferably movable, such that the displacement movement of the guide element can take place transversely to the direction in which the conductors to be connected introduce the conductor connection space. A particularly compact design is thereby achieved, whereby the connection device can be characterized by a reduced installation space.

[0012] In order to be able to form an effective connection between the guide element and the clamping leg of the clamping spring, it can be provided that the guide element has at least one spring abutment edge on which the clamping leg can abut. The spring abutment edge can be designed such that the clamping leg or at least a portion of the clamping leg can abut on the spring abutment edge both in the release position and in the clamping position. The spring abutment edge can be formed, for example, on a shoulder of the guide element.

[0013] In order to be able to achieve a uniform guidance of the guide element and the clamping leg of the clamping spring, two such spring abutment edges can be formed on the guide element, whereby the clamping leg can be guided on the guide element by means of the two such spring abutment edges. The two spring abutment edges preferably extend parallel to one another on the guide element.

[0014] In this design, the clamping leg can have two sliding sections which are arranged on the sides of the main section with the clamping edge, and the guide element has two spring abutment edges which are arranged spaced apart from one another, wherein the first sliding section can abut against the first spring abutment edge and the second sliding section can abut against the second spring abutment edge. The two sliding sections are preferably each shorter in length 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 each can form a runner which can be slid along the respective spring abutment edge. In contrast, the main section is preferably formed straight.

[0015] The length of the two longitudinal side walls of the guide element in the conductor introduction direction can be designed such that the two longitudinal side walls can delimit the conductor connection space on a first side and on a second side opposite the first side. The guide element can thus also form a guide for the introduction of the conductor to be connected into the conductor connection space. The two longitudinal side walls can prevent the conductor from being inserted incorrectly. The conductor connection space can thus be delimited on two of its sides by the guide element and on the other two of its sides by the current bar and the clamping leg of the clamping spring. One of the two spring abutment edges can be formed on each of the two longitudinal side walls.

[0016] In order to enable a stable mounting of the clamping spring, the clamping spring can be supported on the current bar by means of its holding leg. To this end, the clamping spring can for example abut with one section of the holding leg flat against a part of the current bar. Furthermore, the holding leg can also have an opening through which a part of the current bar can be inserted, so that the holding leg can hang on the current bar. The part of the current bar on which the holding leg of the clamping spring is supported is preferably opposite the section of the current bar in which the conductor can be clamped. This part of the current bar can form an end section of the current bar.

[0017] The connection device can also have a trigger element, which can engage with the guide element when the clamping spring is in the release position. The trigger element can be actuated by the conductor connection space when a conductor to be connected is introduced into the conductor connection space, so that the trigger element disengages from the engagement with the guide element and the guide element can be moved by the spring force of the clamping leg in such a way that the clamping leg can be transferred to the clamping position to clamp the conductor on the current bar. By providing a trigger element, it is possible, inter alia, to connect a flexible conductor and clamp it on the current bar without having to actuate the actuating element. In order to be able to hold the guide element in the release position, the guide element can engage in the release position of the clamping leg of the clamping spring with the trigger element. If the trigger element engages with the guide element, the guide element can no longer be able to perform a displacement movement or is stopped. By the effective connection or coupling of the trigger element with the guide element and 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, inter alia, a flexible conductor can be introduced into the conductor connection space thus opened between the conductor current bar and the clamping spring. The trigger element can have a pressure surface pointing in the direction of the conductor connection space, which can be arranged in alignment with the introduction area of the connection device for the conductor or in alignment with the conductor connection space, so that the conductor hits the pressure surface of the trigger element when being introduced into the connection device, whereby a pressure can be exerted from the conductor onto the trigger element. By exerting a pressure on the pressure surface and thus on the trigger element by means of the conductor, the trigger element can perform a pivoting movement or a flipping movement, for example, in the direction of the conductor introduction direction, so that the trigger element can pivot or flip away from the guide element in the direction of the conductor introduction. The pivoting movement of the trigger element can cause the trigger element to disengage from the engagement with the guide element, so that the guide element can again be free to move and the guide element can thus be moved only by the spring force of the clamping leg without manual assistance, so that the clamping leg can be transferred from the release position to the clamping position. By this special mechanism it is possible to connect a flexible conductor particularly simply by the introduction movement of the conductor alone, without the user having to operate further elements, for example the actuating element, to release the clamping spring and move it from the release position to the clamping position. This simplifies the handling of the connection device and saves time when connecting the conductor. The trigger element preferably extends over the region between the section of the current bar on which the conductor can be clamped and the clamping spring, so that the trigger element can delimit the conductor connection space on one side.

[0018] In order to be able to separate the trigger element from the guide element and thus disengage the trigger element from the engagement with the guide element by means of a conductor introduced into the conductor connection space, the trigger element can be mounted in such a way that it can be flipped over relative to the guide element. The trigger element can thus be formed flap-like. If the conductor to be connected is pressed against the trigger element, the trigger element can be flipped over in the direction of the conductor introduction in order to disengage from the engagement with the guide element and thus release the guide element, so that the guide element can again be free to move.

[0019] In order to be able to form the 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 latching lug of the guide element in the release position of the clamping leg of the clamping spring. Thereby, a locking connection between the guide element and the trigger element can be formed when the clamping leg of the clamping spring is in the release position. The trigger element preferably has two undercuts and the guide element preferably has two latching lugs, so that a double-acting locking between the guide element and the trigger element can be formed. If two undercuts are provided, these are preferably formed on two side faces of the trigger element which extend parallel to one another.

[0020] The trigger element can be connected with the holding leg of the clamping spring. The trigger element is preferably connected with the holding leg in such a way that the trigger element can be pivoted relative to the holding leg. The pivot axis is preferably formed in the region of the connection of the trigger element with the holding leg of the clamping spring. The connection between the holding leg and the trigger element is preferably designed in such a way that the holding leg is formed in one piece with the trigger element. However, the trigger element can also be an element or component which is formed separately from the clamping spring, the current bar and the guide element.

[0021] The object according to the application is also achieved by a connection terminal, in particular a terminal block, which has at least one connection device which is formed and further developed as described above. The connection terminal can be arranged on a printed circuit board, for example, if the connection terminal is designed as a terminal block. If the connection terminal is designed as a terminal block, it can be arranged on a support rail.

[0022] It is also possible to provide a connection terminal device which can have a plurality of connection terminals which are arranged in a row, each of which can have at least one connection device which is formed and further developed as described above.

[0023] Furthermore, it is also possible to provide a plug connector which can have one or more connection devices which are formed and further developed as described above.

[0024] Furthermore, the object according to the application can be achieved by an electronic device which can have at least one connection device which is formed and further developed as described above and / or at least one connection terminal which is formed and further developed as described above.

DETAILED DESCRIPTION

[0034] Figure 1 A connection terminal 200 with a housing 210, which can be formed from an insulating material, is shown, in which a connection device 100 for connecting a conductor, not shown here, is arranged or accommodated in the housing 210.

[0035] The connection device 100 has a current bar 110 and a clamping spring 111 designed as a torsion spring, which can be seen in particular in the cross-sectional view in Figure 2 The clamping spring 111 has a retaining leg 112 and a clamping leg 113. The retaining leg 112 is held in a fixed position, while the clamping leg 113 is pivotable relative to the retaining leg 112. By pivoting the clamping leg 113, it can be transferred into the clamping position as shown in Figure 1 and Figure 2 and into the release position as shown in Figure 3 and Figure 4The clamping leg 113 is shown in a clamping position and in a release position. In the clamping position, the clamping leg 113 is pressed against a section 114 of the current bar 110 or against a conductor inserted into the connection device 100 in order to clamp and connect it to 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 can be inserted into the free space formed thereby between the section 114 of the current bar 110 and the clamping leg 113.

[0036] The clamping spring 111 is supported on the current bar 110 by means of its holding leg 112. To this end, in the design variant shown, the holding leg 112 has an opening 132 into which a portion 133 of the current bar 110 extends, so that the holding leg 112 is suspended on the current bar 110. The portion 133 of the current bar 110 forms an end section of the current bar. The portion 133 of the current bar 110 is formed parallel to the section 114 of the current bar 110. Figures 1 to 4

[0037] In addition, the connection device 100 has a guide element 115. The guide element 115 is mounted in particular in such a way that it can be moved relative to the current bar 110, so that the guide element 115 can be moved in a horizontal displacement movement V.

[0038] The clamping leg 113 of the clamping spring 111 can be transferred from the clamping position to the release position and held in the release position by means of the guide element 115. To this end, the guide element 115 is in operative connection with the clamping leg 113 of the clamping spring 111.

[0039] In the design variant shown here, the guide element 115 has two spring abutment edges 116a, 116b arranged parallel to one another, against which the clamping leg 113 abuts.

[0040] 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 on the sides 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 abut against the two spring abutment edges 116a, 116b of the guide element 115, wherein the sliding section 119a abuts against the spring abutment edge 116a and the sliding section 119b abuts against the spring abutment edge 116b. The sliding sections 119a, 119b abut against the spring abutment edges 116a, 116b both in the release position and in the clamping position of the clamping leg 113 of the clamping spring 111.

[0041] ​The sliding sections 119a, 119b have a shorter length than the main section 117. The sliding sections 119a, 119b are curved to form a runner plate shape, by means of which the sliding sections 119a, 119b can slide along the spring abutment edges 116a, 116b when the clamping leg 113 is transferred into the release position and the clamping position, as can be seen in particular in Figure 1 and Figure 3 .

[0042] The two spring abutment 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 one another. The two longitudinal side walls 120a, 120b each have an upper edge 121a, 121b and an opposite lower edge 122a, 122b. The spring abutment edges 116a, 116b each extend perpendicular to the upper edges 121a, 121b. Starting from the horizontally extending upper edges 121a, 121b, the spring abutment edges 116a, 116b extend downward in the direction of the horizontally extending lower edges 122a, 122b of the guide element 115.

[0043] 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 surrounded by the guide element 115.

[0044] The guide element 115 also has two end walls 123a, 123b, which are oriented parallel to one another. The two end walls 123a, 123b are arranged transversely to the two longitudinal side walls 120a, 120b of the guide element 115.

[0045] 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 to be connected can be inserted. The conductor connection space 124 is covered or delimited on the sides 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 to be connected.

[0046] The conductor connection space 124 is designed to be aligned with a conductor introduction opening 211 formed in the housing 210, through which the conductor to be connected can be introduced into the housing 210 of the connection terminal 200.

[0047] The connection device 100 also has a trigger element 125. The trigger element 125 is arranged in alignment with the conductor introduction opening 211 and the conductor connection space 124. The trigger element 125 delimits the conductor connection space 124 toward the bottom.

[0048] 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 Figure 3 and Figure 4 is shown, whereby the guide element 115 is held in its position and whereby the clamping leg 113 is also held in its position by the spring abutting against the edges 116a, 116b and the sliding sections 119a, 119b, so that an unintentional pivoting of the clamping leg 113 from the release position back into the clamping position can be prevented.

[0049] 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 are respectively in engagement with the latching lugs 127a, 127b of the guide element 115, in order to form a latching between the guide element 115 and the trigger element 125. The latching lug 127a is formed on the lower edge 122a of the longitudinal side wall 120a, and the latching lug 127b is formed on the lower edge 122b of the longitudinal side wall 120b.

[0050] In the clamping position, the trigger element 125 is disengaged from the guide element 115, as shown in Figure 1 and Figure 2 so that the guide element 115 can move freely.

[0051] The trigger element 125 is mounted so as to be able to be flipped over relative to the guide element 115.

[0052] When a conductor to be connected is introduced into the conductor connection space 124 through the conductor introduction opening 211 in the introduction direction E, the conductor hits the trigger element 125, so that the trigger element 125 is flipped over relative to the guide element 115 and thereby disengaged from the guide element 115, so that the guide element 115 can again move freely and thus the guide element 115 can move only by the spring force of the clamping leg 113 without manual assistance, so that the clamping leg 113 can be transferred from the release position into the clamping position. The trigger element 125 has a pressure surface 128 directed in the direction of the conductor connection space 124, which is aligned with the conductor introduction opening 211 or is arranged aligned with the conductor connection space 124, so that when the conductor is introduced into the conductor connection device 100, it hits the pressure surface 128 of the trigger element 125, whereby the trigger element 125 is subjected to pressure by the conductor. By means of the pressure exerted by the conductor onto the pressure surface 128 and thus onto the trigger element 125, the trigger element 125 is subjected to a pivoting or flipping movement in the direction of the introduction direction E of the conductor, so that the trigger element 125 can be pivoted or flipped away from the guide element 115 in the introduction direction E of the conductor.

[0053] In the design variant shown here, in particular in Figure 4As can be seen, the trigger element 125 is connected to the holding leg 112 of the clamping spring 111. The trigger element 125 is connected in such a way that it can pivot relative to the holding leg 112, which is held in a fixed position. The pivot axis can be formed in the region in which the trigger element 125 is connected to the holding leg 112.

[0054] When the guide element 115 is disengaged from the trigger element 125, the displacement movement V of the guide element 115 takes place in a direction oriented transversely to the introduction direction E of the conductor to be connected into the conductor-to-conductor connection space 124.

[0055] In order to displace the clamping leg 113 by means of the guide element 115 from the clamping position back into the release position against the spring force of the clamping spring 111, the connection device 100 has a handling element 129. The handling element 129 is mounted in such a way that it can be moved in a handling direction B, wherein the handling direction B is parallel to the introduction direction E of the conductor. The handling direction B extends transversely to the displacement movement V of the guide element 115.

[0056] The guide element 115 can be moved by means of the handling element 129 in such a way that the clamping leg 113 of the clamping spring 111, which bears against the guide element 115, can be displaced from the clamping position into the release position. When the handling element 129 is handled in the handling direction B, the handling element 129 can be moved in such a way that it exerts a pressure on the guide element 115 in order to displace the guide element 115 against the spring force of the clamping leg 113 of the clamping spring 111, so that the guide element 115 can engage the trigger element 125 when the clamping leg 113 reaches the release position. This displacement movement V of the guide element 115 results in the clamping leg 113 being pivoted from the clamping position into the release position.

[0057] The guide element 115 has a sliding surface 130 designed in the form of an inclined plane along which the handling element 129 can be guided. In the design variant 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 handling element 129. The sliding surface 129 is arranged inclined due to the design as an inclined plane, so that the sliding surface 129 extends here at an angle of between 130° and 160° to the end wall 123b of the guide element 115.

[0058] Alternatively, the sliding surface 130 can also 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 connected directly to the longitudinal side walls 120a, 120b.

[0059] The actuating element 129 also has a ramp 131 designed to correspond to the inclination of the sliding surface 130. The ramp 131 of the actuating element 129 rests flat against the sliding surface 130, such that when the actuating element 129 is actuated in the actuation direction B, the ramp 131 can slide downward along the sliding surface 130 to move the guide element 115. The inclination of the sliding surface 130 and the inclination of the ramp 131 preferably have an angle between 30° and 50° with respect to the actuation direction B of the actuating element 129.

[0060] The actuating element 129 is arranged near the retaining leg 112 of the clamping spring 111. The actuating element 129 is therefore arranged after the clamping spring 111. The clamping spring 111 is arranged between the section 114 of the current bar 110 and the actuating element 129.
