Description

Technical Field

[0001] The present invention relates to a wiring arrangement for connecting electrical conductors. The present invention also relates to an electronic device. Background Art

[0002] This type of connection arrangement typically features a clamping spring designed as a leg spring with a retaining foot and a clamping foot. A conductor inserted into the connection arrangement can be clamped against the current bar by means of the clamping foot of the clamping spring. If a flexible conductor is to be clamped, the clamping spring must be moved to a released position and then actuated by means of an actuating element before the conductor is inserted. This allows the clamping spring or the clamping foot to be deflected away from the current bar in order to insert the conductor into the intermediate space between the current bar and the clamping spring. Only when the conductor is rigid and therefore stable can it exert sufficient force on the clamping spring or its clamping foot to deflect the clamping foot away from the current bar without the user having to actuate the actuating element. For flexible conductors, the user must first actuate the actuating element to deflect the clamping spring away from the current bar in order to insert the flexible conductor. To clamp the inserted conductor, the user must manually actuate the actuating element again to move the clamping spring from the released position to the clamped position. Manual manipulation of the manipulation element makes the installation or connection of the conductor more difficult for the user, since the operation is cumbersome and thus time-consuming. Summary of the Invention

[0003] It is therefore an object of the present invention to provide a wiring arrangement and an electronic device in which the connection of, in particular, flexible conductors can be simplified.

[0004] The solution of the present invention for achieving the above-mentioned object is characterized by the independent claim. Preferred embodiments and advantageous improvements of the present invention are described in the dependent claims.

[0005] The connection arrangement of the present invention comprises: a housing; a current bar; a clamping spring having clamping feet that can be moved into a clamping position and a release position; a conductor connection cavity formed between a section of the current bar and the clamping feet of the clamping spring; a movably arranged guide element that is operatively connected to the clamping feet of the clamping spring, wherein the clamping feet can be held in the release position by means of the guide element; and a triggering element that engages with the guide element in the release position of the clamping spring. When a conductor to be connected is inserted into the conductor connection cavity, the triggering element can be actuated by the conductor so that the triggering element is disengaged from the guide element and the guide element can be moved by the spring force of the clamping feet, thereby moving the clamping feet into the clamping position to clamp the conductor against the current bar. The connection arrangement also comprises an actuating element by which the guide element can be moved to move the clamping feet of the clamping spring from the clamping position to the release position, wherein the actuating element has a display element for indicating the connection status of the electrical conductor.

[0006] The connection arrangement according to the present invention allows flexible conductors to be connected and clamped against a current bar without manual actuation of, for example, an operating element or without the aid of tools. The clamping spring is preferably designed as a leg spring having a retaining foot and a clamping foot that can be pivoted relative to the retaining foot. The pivoting movement of the clamping foot allows the clamping foot to be moved into a release position and a clamping position. In the release position, the clamping foot is spaced apart from the current bar, and the conductor to be connected can be inserted into or removed from the conductor connection cavity formed between the current bar and the clamping foot. In the clamping position, the clamping foot can rest against the current bar or against the connected conductor, thereby clamping the conductor against the current bar. The connection arrangement includes a guide element, which is preferably mounted so as to be horizontally displaceable. The guide element is preferably in operative connection with the clamping spring in both the release position and the open position of the clamping foot. This means that the clamping spring can follow the displacement movement of the guide element and thus its position due to its operative connection to the guide element. The guide element holds the clamping foot in the released position against its spring force by pressing it against the clamping foot. To hold the guide element in this position, the guide element engages with the trigger element in the released position of the clamping foot of the clamping spring. If the trigger element engages with the guide element, the guide element cannot perform a displacement movement, or the displacement movement is stopped. The operative connection or coupling of the trigger element to the guide element and the guide element to the clamping foot of the clamping spring in the released position of the clamping foot allows the clamping foot to be held in this released position without additional manual manipulation. This allows, in particular, the insertion of a flexible conductor into the conductor connection cavity thus freed between the current bar and the clamping spring. The trigger element can have a pressing surface pointing toward the conductor connection cavity, which is aligned with an insertion area for the conductor into the wiring arrangement, or aligned with the conductor connection cavity, so that the conductor strikes the pressing surface of the trigger element when inserted into the wiring arrangement, thereby applying a pressing force to the trigger element from the conductor. By applying a pressing force to the pressing surface and thus to the trigger element via the conductor, the trigger element can, for example, be caused to engage in a deflecting or tilting movement in the direction of conductor insertion, thereby deflecting or tilting the trigger element away from the guide element in the direction of conductor insertion. This deflecting movement of the trigger element disengages the trigger element from the guide element, allowing the guide element to move freely again. The guide element can then be moved unassisted, solely by the elastic force of the clamping feet, allowing the clamping feet to move from a released position to a clamped position. This special mechanism makes it particularly easy to connect flexible conductors simply by the insertion movement of the conductor, without the user having to manipulate other elements, such as an operating element, to release the clamping spring and move it from the released position to the clamped position. This simplifies the handling of the wiring arrangement and saves time when connecting the conductors.The trigger element is preferably an element or component designed independently of the clamping spring, the current bar, and the guide element. The trigger element preferably extends in the region between the conductor-clamping section of the current bar and the clamping spring, so that the trigger element can delimit the conductor connection space on one side. The guide element can be designed as a slider element.

[0007] According to the present invention, the wiring arrangement further comprises an operating element, by means of which the guide element can be moved in order to move the clamping foot of the clamping spring from the clamping position into the released position. The operating element can preferably be constructed in such a way that a pressing force is applied to the guide element so that this guide element moves in the opposite direction to the elastic force of the clamping foot of the clamping spring, so that after reaching the released position of the clamping foot, the guide element can engage with the triggering element. By means of a displacement movement, the guide element can apply a tensile force to the clamping foot of the clamping spring so that the clamping foot moves from the clamping position into the released position. The operating element can preferably be moved in a direction that is oriented transversely to the direction of the displacement movement of the guide element. The operating element can preferably be moved in a purely translational manner. The direction of movement of the operating element is preferably oriented parallel to the insertion direction of the conductor into the conductor connection cavity. In order to enable the user to see the connection state of the electrical conductor on the wiring arrangement, the operating element has a display element for displaying the connection state of the electrical conductor. The user can visually detect via the display element whether an electrical conductor inserted into the connection arrangement has been clamped against the current bar by means of the clamping spring, or whether the conductor has been inserted into the housing of the connection arrangement but the triggering element has not yet been triggered, and thus the clamping spring has not yet reached the clamping position. The display element, which is integrated into the operating element, provides continuous visual feedback on the connection status of the conductor to be connected, regardless of the diameter of the electrical conductor.

[0008] The connection arrangement can be, for example, part of a terminal block, a terminal strip, or a plug-in connector. A plurality of connection points can also be provided in the housing of the connection arrangement, each connection point having a corresponding current bar, a corresponding clamping spring, a corresponding actuating element, a corresponding guide element, and a corresponding triggering element, so that the connection points arranged in the housing are preferably all designed in the same way.

[0009] The display element is preferably formed on an end section of the operating element, which can extend from the housing opening when the conductor is connected, so that at least a section of the display element can extend from the housing opening when the conductor is connected. This provides clear visual feedback to the user, indicating that the conductor is clamped between the clamping spring and the current bar and is therefore connected. If the conductor is not yet clamped and therefore not connected, the end section of the operating element and the display element are preferably still within the housing and not extending from the housing opening, so that the display element is still not visible to the user. This allows the user to visually indicate the connection status of the electrical conductor simply by the position of the display element.

[0010] The display element can be implemented, for example, in the form of a tab-shaped extension on the end section of the operating element. It can be seen that when the conductor is connected, the tab-shaped extension protrudes from the opening of the housing. The tab-shaped extension preferably has a smaller width and / or a smaller thickness than the rest of the operating element.

[0011] To operate the operating element, the operating element may have a tool receiving area. In this case, the display element is preferably arranged adjacent to the tool receiving area. The tool receiving area may, for example, be shaped like a groove to accommodate a tool, such as a screwdriver. By arranging the display element adjacent to the tool receiving area, the display element also serves as a guide for the tool as it moves toward the tool receiving area. Furthermore, when the operating element is operated using a tool, the display element can form a contact edge for the tool inserted into the tool receiving area.

[0012] The actuating element is preferably arranged so that it does not penetrate the conductor connection cavity, thus preventing the actuating element from interacting with the connected conductor. The clamping spring, current bar, and actuating element are preferably arranged so that the clamping spring is disposed between a section of the current bar and the actuating element, and the conductor to be connected is clamped against this section. This significantly simplifies the handling of the wiring arrangement for the user when connecting electrical conductors, because the actuating element is located away from the conductor connection cavity, so that insertion of the conductor is not hindered by actuation of the actuating element.

[0013] In order to establish an operative connection between the guide element and the clamping foot of the clamping spring, the guide element can have at least one spring contact edge against which the clamping foot can rest. The spring contact edge can be designed such that at least a portion of the clamping foot can rest against the spring contact edge both in the released position and in the clamped position of the clamping foot. The spring contact edge can be formed, for example, on a shoulder of the guide element.

[0014] In order to be able to guide the guide element and the clamping foot of the clamping spring uniformly, two such spring abutment edges are formed on the guide element so that the clamping foot is guided on these two spring abutment edges on the guide element. These two spring abutment edges preferably extend parallel to each other on the guide element.

[0015] In this technical solution, the clamping foot has two sliding sections arranged on the sides of a main section having a clamping edge. The guide element has two spring-loaded edges spaced apart from each other, wherein the first sliding section can abut against the first spring-loaded edge, and the second sliding section can abut against the second spring-loaded edge. The two sliding sections are preferably shorter than the main section of the clamping foot. The main section and the two sliding sections preferably extend parallel to each other. The two sliding sections are preferably arcuate, each forming a slide that can slide along a respective spring-loaded edge. The main section is preferably straight.

[0016] The guide element is preferably movable in such a way that the displacement movement of the guide element can be carried out transversely to the insertion direction of the conductor to be connected into the conductor connection cavity. This allows for a particularly compact design, whereby the installation space of the connection arrangement is reduced.

[0017] In order to separate the trigger element from the guide element and thereby disengage the guide element by inserting a conductor into the conductor connection cavity, the trigger element is supported so as to be tiltable relative to the guide element. Thus, the trigger element can be shaped like a seesaw. If the conductor to be connected presses against the trigger element, the trigger element can tilt in the direction of insertion of the conductor to disengage the guide element, thereby releasing the guide element and allowing it to move freely again.

[0018] To achieve the locking engagement between the trigger element and the guide element when the clamping spring's clamping foot is in the released position, the trigger element can have at least one undercut that can engage with at least one snap-on flange of the guide element when the clamping spring's clamping foot is in the released position. This creates a snap-on connection between the guide element and the trigger element when the clamping spring's clamping foot is in the released position. The trigger element preferably has two undercuts, and the guide element preferably has two snap-on flanges, thereby creating a dual-action snap-on connection between the guide element and the trigger element. If two undercuts are provided, these are preferably formed on two parallel side faces of the trigger element. In this case, the trigger element has a T-shape due to the two undercuts.

[0019] Furthermore, the guide element preferably has two mutually parallel longitudinal side walls, which can delimit the conductor connection cavity on a first side and a second side opposite the first side. Thus, when a conductor to be connected is inserted into the conductor connection cavity, the guide element also serves as a guide for the conductor to be connected. These two longitudinal side walls can prevent the conductor from being inserted incorrectly. Thus, the conductor connection cavity can be delimited on two sides by the guide element and on two other sides by the current bar and the clamping legs of the clamping spring.

[0020] The guide element may have a sliding surface along which the operating element may be guided. The operating element may rest flatly against the guide element on the sliding surface. The operating element may slide along the guide element on the sliding surface, thereby transmitting a pressing force to the guide element.

[0021] The sliding surface can be arranged between the two longitudinal side walls of the guide element or on an end wall of the guide element. The sliding surface is preferably oriented such that it extends transversely to the two longitudinal side walls. Arranging the sliding surface between the two longitudinal side walls allows an actuating element for actuating the guide element to be inserted into the free space defined by the two longitudinal side walls and the sliding surface. The two longitudinal side walls can form guiding aids for the actuating element, preventing the actuating element from tilting when guided along the sliding surface of the guide element.

[0022] The sliding surface can be formed as an inclined surface, which can interact with an inclined surface formed on the operating element. If the sliding surface is formed as an inclined surface, the inclined surface preferably has an inclination. In this case, the surface of the operating element that abuts the sliding surface is preferably also formed as an inclined surface, which is inclined relative to the longitudinal extension of the operating element extending along the direction of movement of the operating element. If both the sliding surface and the surface of the operating element that slides along the sliding surface are formed as inclined surfaces, then when the operating element slides along the sliding surface, the vertical movement of the operating element can be converted into a horizontal displacement movement of the guide element.

[0023] The operating element preferably has a locking region within which the operating element can be held in a fixed position on the guide element when the clamping spring is in the released position. By holding the operating element in a fixed position on the guide element and thus in the locked position, undesired rearward movement of the operating element can be prevented. Preferably, the operating element is released from its fixed position on the guide element when the conductor to be connected actuates the trigger element, thereby moving the clamping spring from the released position into the clamped position. In the clamped position of the clamping spring, the locking region of the operating element is preferably separated from the guide element, so that the operating element can be moved away from the guide element in a manner that allows an indicator element of the operating element to indicate the clamped state of the conductor. The locking region is preferably formed at an end section of the operating element, which is separated from the end section on which the indicator element is formed.

[0024] The locking region can be designed, for example, such that in the released position of the clamping spring it can at least partially engage the sliding surface of the guide element. To this end, the locking region has two guide arms that can at least partially engage the guide surface from behind and thus hook onto the sliding surface from behind.

[0025] In addition, the locking area can also have one or two retaining pins, which can respectively hook into a groove that is constructed on the guide element. On the two longitudinal side walls of the guide element, one of the grooves can be constructed respectively.

[0026] To assist the guide element's displacement, the guide element can be connected to a spring element. The spring element is preferably designed as a compression spring. The spring element is preferably tensioned between the guide element and the inside of the housing. The spring element can apply a horizontally acting pressure to the guide element, thereby assisting its displacement when the clamping spring moves from the released position to the clamped position. The spring element is always able to move or press the guide element into its end position in the clamped position of the clamping spring, regardless of the diameter of the conductor to be connected.

[0027] The object of the present invention can also be achieved by an electronic device which can have at least one wiring configuration constructed and improved as described above. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Figures 1 to 6 A connection arrangement 100 is shown, which has a housing 132 , which can be formed from an insulating material, wherein a conductor entry 133 for inserting and connecting an electrical conductor 200 is formed in the housing 132 .

[0044] Especially if Figure 3 As shown in the sectional view in FIG, the connection arrangement 100 has a current bar 110 and a clamping spring 111 designed as a leg spring. The clamping spring 111 has a holding foot 112 and a clamping foot 113. The holding foot 112 remains in a fixed position, while the clamping foot 113 can be deflected relative to the holding foot 112. By the deflection movement of the clamping foot 113, this clamping foot can be moved into a clamping position (such as Figures 4 to 6 as shown) and into the release position (as Figures 1 to 3 ). In the clamping position, the clamping legs 113 press against a section 114 of the current bar 110 or against a conductor 200 inserted into the connection arrangement 100 in order to clamp and connect this conductor to the section 114 of the current bar 110. In the released position, the clamping legs 113 are spaced apart from the section 114 of the current bar 110, so that the conductor 200 can be inserted into the free space or conductor connection cavity 124 thus formed between the section 114 of the current bar 110 and the clamping legs 113.

[0045] Furthermore, the connection arrangement 100 has a guide element 115. The guide element 115 is mounted in particular so as to be displaceable relative to the current bar 110, so that the guide element 115 can perform a horizontal displacement movement.

[0046] The clamping foot 113 of the clamping spring 111 can be moved from the clamping position into the release position and held in the release position by means of the guide element 115. For this purpose, the guide element 115 is in operative connection with the clamping foot 113 of the clamping spring 111.

[0047] In order to form an operative connection, in the solution shown here the guide element 115 has two mutually parallel spring-loaded abutment edges 116 a , 116 b , against which the clamping foot 113 rests.

[0048] The clamping foot 113 has a main section 117 with a clamping edge 118 formed at its free end. Two sliding sections 119a and 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 and 119b. The two sliding sections 119a and 119b abut against the two spring abutment edges 116a and 116b of the guide element 115, with the sliding section 119a abutting against the spring abutment edge 116a and the sliding section 119b abutting against the spring abutment edge 116b. The sliding sections 119a and 119b can abut against the spring abutment edges 116a and 116b in both the released and clamped positions of the clamping foot 113 of the clamping spring 111.

[0049] The sliding sections 119a, 119b are shorter than the main section 117 of the clamping foot 113 of the clamping spring 111. The sliding sections 119a, 119b are arcuate, thereby forming a sled shape, and with the help of this sled shape, when the clamping foot 113 is moved into the release position and the clamping position, the sliding sections 119a, 119b can slide along the spring abutment edges 116a, 116b.

[0050] The two spring abutment edges 116a, 116b are formed on opposing longitudinal side walls 120a, 120b of the guide element 115. The two longitudinal side walls 120a, 120b are parallel to each other. The two longitudinal side walls 120a, 120b each have an upper edge 121a, 121b and an opposing lower edge 122a, 122b. The spring abutment edges 116a, 116b extend perpendicularly to the upper edges 121a, 121b. From the horizontally extending upper edges 121a, 121b, the spring abutment edges 116a, 116b extend downward toward the horizontally extending lower edges 122a, 122b of the guide element 115.

[0051] The current bar 110 and the clamping spring 111 are arranged between 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.

[0052] The guide element 115 further comprises two mutually parallel end walls 123 a , 123 b , which are arranged transversely to the two longitudinal side walls 120 a , 120 b of the guide element 115 .

[0053] A conductor connection cavity 124, into which the conductor to be connected can be inserted, is formed between the section 114 of the current bar 110 and the clamping foot 113 of the clamping spring 111. The conductor connection cavity 124 is laterally covered or bounded by two longitudinal side walls 120a, 120b of the guide element 115, so that the guide element 115 also forms a guide for the conductor 200 to be connected.

[0054] The conductor connection cavity 124 is flush with a conductor entry 133 formed in the housing 132 , via which the conductor 200 to be connected can be inserted into the housing 132 of the wiring arrangement 100 .

[0055] The connection arrangement 100 further comprises a trigger element 125. The trigger element 125 is flush with the conductor inlet 133 and the conductor connection chamber 124. The trigger element 125 delimits the conductor connection chamber 124 from below.

[0056] like Figures 1 to 3 As shown, in the released position of the clamping foot 113 of the clamping spring 111, the trigger element 125 is engaged with the guide element 115, so that the guide element 115 is maintained in its position, whereby the clamping foot 113 is also maintained in its position by the spring-loaded edges 116a, 116b and the sliding sections 119a, 119b, thereby preventing the clamping foot 113 from rotating unexpectedly from the released position to the clamping position.

[0057] The trigger element 125 has two bottom cutouts 126 arranged on the side, which respectively engage with a locking flange 127a, 127b of the guide element 115 in the released position of the clamping foot 113 of the clamping spring 111 to form a locking connection between the guide element 115 and the trigger element 125. The locking flange 127a is formed on the lower edge 122a of the longitudinal side wall 120a, and the locking flange 127b is formed on the lower edge 122b of the longitudinal side wall 120b.

[0058] like Figures 4 to 6 As shown, in the clamping position, the trigger element 125 is disengaged from the guide element 115 , so that the guide element 115 can move freely.

[0059] The triggering element 125 is supported in a tiltable manner relative to the guide element 115 .

[0060] When the conductor 200 to be connected is inserted into the conductor connection cavity 124 through the conductor entrance 133 along the insertion direction E, the conductor 200 hits the trigger element 125, causing the trigger element 125 to tilt relative to the guide element 115, thereby disengaging from the engagement with the guide element 115, allowing the guide element 115 to move freely again. As a result, the guide element 115 can be moved without human assistance only by the elastic force of the clamping foot 113, so that the clamping foot 113 can be moved from the release position to the clamping position. The trigger element 125 has a pressing surface 128 pointing to the conductor connection cavity 124, as shown in FIG. Figure 6 As shown, the pressing surface is arranged flush with the conductor inlet 133 or flush with the conductor connection cavity 124, so that when the conductor 200 is inserted into the wiring arrangement 100, it strikes the pressing surface 128 of the triggering element 125, so that the conductor 200 applies a pressing force to the triggering element 125. By applying a pressing force to the pressing surface 128 and thus to the triggering element 125 by means of the conductor 200, the triggering element 125 can be caused to enter into a deflection movement or tilting movement along the insertion direction E of the conductor 200, so that the triggering element 125 is deflected or tilted away from the guide element 115 along the insertion direction E of the conductor 200.

[0061] When the guide element 115 is disengaged from the trigger element 125 , the guide element 115 performs a displacement movement V in a direction transverse to the insertion direction E of the conductor 200 to be connected into the conductor connection cavity 124 .

[0062] In order to move the clamping feet 113 back from the clamping position to the release position against their spring force by means of the guide element 115, the connection arrangement 100 has an actuating element 129. The actuating element 129 is mounted in the housing 132 so as to be movable along an actuating direction B, wherein the actuating direction B is parallel to the insertion direction E of the conductor 200. The actuating direction B extends transversely to the displacement movement V of the guide element 115.

[0063] The guide element 115 can be displaced by means of the actuating element 129 such that the clamping foot 113 of the clamping spring 111, which rests against the guide element 115, can be moved from the clamped position into the released position. When the actuating element 129 is actuated in the actuating direction B, the actuating element 129 can be displaced such that a pressing force is applied to the guide element 115, causing the guide element 115 to move counter to the spring force of the clamping foot 113 of the clamping spring 115. After reaching the released position of the clamping foot 113, the guide element 115 can engage with the triggering element 125. This displacement movement V of the guide element 115 deflects the clamping foot 113 from the clamped position into the released position.

[0064] For example, from Figure 3As can be seen, the guide element 115 has a sliding surface 130 designed 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 integrally formed on the end wall 123b of the guide element 115. The sliding surface 130 extends from the end wall 123b toward the actuating element 129. Due to the inclined surface design, the sliding surface 130 is arranged at an angle, so that the sliding surface 130 extends at an angle of 130° to 160° relative to the end wall 123b of the guide element 115.

[0065] Alternatively, the sliding surface 130 can also be arranged between the two longitudinal side walls 120 a , 120 b at a distance from the end wall 123 b , so that the sliding surface 130 directly engages the longitudinal side walls 120 a , 120 b .

[0066] The operating element 129 further has an inclined surface 131 configured to correspond to the inclination of the sliding surface 130. The inclined surface 131 of the operating element 129 abuts against the sliding surface 130 in a planar manner so that when the operating element 129 is operated in the operating direction B, the inclined surface 131 can slide downward along the sliding surface 130 to move the guide element 115.

[0067] The actuating element 129 is arranged adjacent to the retaining foot 112 of the clamping spring 111. The actuating element 129 is therefore 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.

[0068] A display element 134 for displaying the connection state of the electrical conductor 200 to be connected is formed on the operating element 129 at the end section of the operating element 129 that is arranged opposite the inclined surface 131. Thus, the display element 134 is formed at the free end of the operating element 129. The display element 134 is oriented so that it faces outward from the guide element 115.

[0069] from Figures 3 to 6 It can be seen that in the released position of the clamping spring 111 , the actuating element 129 is recessed to a certain extent into the housing 132 , so that the display element 134 is located inside the housing 132 and is therefore not visible to the user from the outside.

[0070] Especially from Figures 1 to 3 As can be seen, when the clamping spring 111 moves from the released position to the clamped position, the operating element 129 moves upward. When the clamped position is reached, the operating element 129 moves upward to such an extent that the display element 134 protrudes from the opening 135 of the housing 132 and is visible to the user. The user can see that the conductor 200 is connected by the display element 134 protruding from the opening 135. The opening 135 is arranged on the same side of the housing 132 as the conductor inlet 133.

[0071] In the embodiment shown here, the display element 134 is formed in the form of a tab-shaped extension 136 on the end section of the actuating element 129. In the clamping position of the clamping spring 111, the display element 134 projects from the opening 135 of the housing 132 with at least one section of the tab-shaped extension 136, so that the tab-shaped extension 136 or this part of the display element 134 protrudes above the housing 132. Compared to the rest of the actuating element 129, the tab-shaped extension 136 has a smaller width and / or a smaller depth or thickness.

[0072] The operating element 129 has a tool receiving area 137 on its end section, which is also equipped with a display element 134. A tool, such as a screwdriver, can be inserted into the tool receiving area to operate the operating element 129. The tool receiving area 137 is designed as a groove or slot. The display element 134 is arranged adjacent to the tool receiving area 137. As a result, the display element 134 can serve as an insertion aid for inserting a tool into the tool receiving area 137 and can also serve as a support aid for the inserted tool when operating the operating element 129.

[0073] In order to keep the actuating element 129 in a fixed position on the guide element 115 in the released position of the clamping spring 111, in particular the display element 134 also remains submerged under the housing 132 and does not protrude from the opening 135, in particular as Figure 7 As shown, the actuating element 129 has a latching region 138 . The latching region 138 can snap or hook the actuating element 129 onto the guide element 115 from behind, thereby holding the actuating element 129 in a fixed position relative to the guide element 115 .

[0074] exist Figure 7 In the illustrated embodiment, the locking region 138 is designed such that, in the released position of the clamping spring 111, this locking section at least partially engages the sliding surface 130 of the guide element 115. To this end, the locking region 138 has two guide arms 140a, 140b, which, in the released position of the clamping spring 111, at least partially engage two opposing edge surfaces 139a, 139b of the sliding surface 130. The guide arms 140a, 140 are arranged opposite the inclined surface 131 of the actuating element 129, so that a free space is formed between the inclined surface 131 and the guide arms 140a, 140, into which the sliding surface 130 of the guide element 115 is immersed in the released position of the clamping spring 111.

[0075] If the triggering element 125 is actuated by the conductor 200 due to the insertion of this conductor and the engagement between the triggering element 125 and the guide element 115 is released, the engagement between the locking region 138 and the guide element 115 is also released by the guide element 115 being moved away from the actuating element 129 in the direction of the displacement movement V. In the clamping position of the clamping spring 111, the locking region 138 is disengaged from the guide element 115.

[0076] Figure 8 and Figure 9 A solution is shown in which the locking region 138 is designed in the form of two opposing retaining pins 141, which can each be snapped onto the guide element 115. The retaining pins 141 are each arranged on an edge surface 142 of the bevel 131, so that the retaining pins 141 each protrude laterally from the bevel 131 or from both edge surfaces 142 of the bevel 131.

[0077] A groove 143 is formed on each of the two longitudinal side walls 120a, 120b of the guide element 115, and one of the two retaining pins 141 is sunken into, hooked into, or snapped into the groove in the release position, so that the operating element 129 snaps into engagement with the guide element 115, and the operating element 129 can be held in a fixed position relative to the guide element 115. In this case, Figure 8 As shown, one of the two retaining pins 141 is sunk into the groove 143 of the longitudinal side wall 120 a , while the other of the two retaining pins is sunk into the groove 143 of the longitudinal side wall 120 b . Figure 9 The clamping position of the clamping spring 111 is shown, in which the retaining pin 141 is guided out of the groove 143 , so that the guide element 115 no longer engages with the actuating element 129 .

[0078] exist Figures 1 to 9 In both illustrated embodiments, a spring element 144 is provided to assist the displacement movement V of the guide element 115 . The spring element 144 remains tensioned between the guide element 115 and the housing 132 .

[0079] The spring element 144 is constructed as a compression spring. The spring element 144 has the shape of a coil spring. The spring element 144 is tensioned in the release position of the clamping spring 111. If the engagement between the guide element 115 and the trigger element 125 is released, the spring element 144 presses the guide element 115, wherein the force of the spring element 144 acts in the direction of the displacement movement V of the spring element 144, thereby pressing or moving the guide element 115 in the clamping position of the clamping spring 111 to its end position by the pressing force of the spring element 144. Figures 1 to 9In the illustrated embodiment, the guide element is pressed or moved as far to the left as possible. The spring element 144 rests against the end wall 123b of the guide element 115. The spring element 144 can be connected to the guide element 115 by riveting, for example.

[0080] Figure 10 and Figure 11 As shown, the position ratio of the clamping spring 111 to the guide element 115 can be adjusted by varying the position of the snap-in projections 127a, 127b on the guide element 115. For positionally accurate feeding of the conductor 200 toward the trigger element 125, an optimized ratio a / b can be set, wherein the value a defines the distance between the clamping edge 118 of the clamping foot 113 and the section 114 of the current bar 110, and the value b defines the distance between the spring contact edges 116a, 116b of the guide element 115 and the snap-in projections 127a, 127b of the guide element 115. Figure 11 A maximum ratio a / b = 1.5 mm / 1.9 mm is shown. Figure 10 A minimum ratio a / b = 3.0 mm / 3.0 mm is shown.

[0081] This position ratio, which can be specifically set via the ratio a / b, can reduce the triggering force of the conductor 200 required to actuate the triggering element 125, since the clamping edge 118 of the clamping spring 111 in the released position can be positioned in such a way, depending on the thickness of the conductor 200, that the clamping edge 118 can guide the conductor 200 in a targeted manner toward the triggering element 125. This is particularly advantageous in the case of flexible conductors 200.

[0082] The snap-on projections 127a, 127b can be positioned by a specifically selected ratio a / b such that they advance the clamping legs 113 of the clamping spring 111 into a specific bending position, in order to deflect the flexible conductor 200 in particular toward the free end 145 of the triggering element 125, thereby deflecting the generated lever force as far away from the rotation axis of the triggering element 125 as possible toward the triggering element 125. The clamping legs 113 bent in this way can compress the strands of the flexible conductor 200 having a larger diameter and guide them toward the section 114 of the current bar 110.

[0083] When the rigid conductor 200 is used, corresponding to straight insertion, the bent clamping legs 113 can be pressed toward the retaining legs 112 in the opposite direction to the elastic force of the clamping legs 113 .

[0084] Figure 12 and Figure 13A technical solution is shown, in which the wiring arrangement 100 is constructed in the form of a terminal block, in particular a terminal block, wherein the wiring arrangement 100 is constructed so that a plurality of conductors 200 can be connected simultaneously in the housing 132, specifically in that a plurality of connection points are provided in the housing 132, which can be connected according to Figures 1 to 9 The technical solutions shown are constructed separately.

[0085] Figure 12 It is shown that exactly one conductor 200 has been inserted into the housing 132 , but the conductor 200 has not yet actuated the triggering element 125 , so that the clamping spring is still in the released position, whereby the display element 134 of the actuating element 129 is still arranged in the housing 132 and is not yet visible to the user from the outside.

[0086] Figure 13 An arrangement is shown in which the display element 134 of the respective operating element 129 projects from an opening 135 of the housing 132 , thereby indicating to the user that the clamping spring 111 is in the clamped position.
