Abstract
Description
Field of the Invention
[0001] The present invention relates to a wiring device for connecting electrical conductors. The present invention also relates to a terminal block, in particular a junction box, having such a wiring device. Background Art
[0002] Such a wiring device typically has a clamping spring configured as a torsion spring, which has a retaining leg and a clamping leg. A conductor inserted into the wiring device can be clamped to a busbar 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 transferred to an open position by means of an operating element before the conductor is inserted and operated to pivot the clamping spring or the clamping leg away from the busbar, so that the conductor can be inserted into the intermediate space between the busbar and the clamping spring. Only in the case of a rigid and thus stable conductor can the conductor exert sufficient force on the clamping spring or the clamping leg of the clamping spring to enable the clamping leg to pivot away from the busbar without the user having to operate the operating element for this purpose. In the case of a flexible conductor, the user must first operate the operating element to pivot the clamping spring away from the busbar so that the flexible conductor can be inserted. To clamp the inserted conductor, the user must again manually operate the operating element to transfer the clamping spring from the open position to the clamping position. For the user, the manual operation of the operating element makes the assembly or wiring of the conductor difficult because the manual manipulation is cumbersome and thus also increases the time consumption. Summary of the Invention
[0003] The object of the present invention is to provide a wiring device in which the wiring of particularly flexible conductors can be simplified.
[0004] According to the present invention, this object is solved by the features of the independent claims. Suitable designs and advantageous improvements of the present invention are given in the dependent claims.
[0005] The connection device according to the invention has: a housing with a conductor insertion opening; a busbar arranged in the housing; a clamping spring arranged in the housing, which has a holding leg and a clamping leg, wherein the clamping leg can be transferred into a clamping position and an open position; and an operating element by means of which the clamping leg can be transferred from the clamping position into the open position. Furthermore, the connection device has a triggering element which, in the open position of the clamping leg, engages with the clamping leg in such a way that the clamping leg is held in the open position by means of the triggering element, and which can be pivoted in such a way that a conductor to be connected, when inserted into the conductor insertion opening in the insertion direction, can operate the triggering element in such a way that the clamping leg disengages from the triggering element and pivots from the open position into the clamping position. The operating element has an operating arm, wherein, when the triggering element is not triggered by the conductor to be connected, the operating arm of the operating element interacts with the triggering element in such a way that the clamping leg disengages from the triggering element and pivots from the open position into the clamping position.
[0006] Now, with the wiring device according to the present invention, flexible conductors can also be simply and reliably connected and clamped on the busbar. The clamping spring is preferably configured as a torsion spring, which has a retaining leg and a clamping leg configured to pivot relative to the retaining leg. Through the pivoting movement of the clamping leg of the clamping spring, the clamping leg can be transferred to an open position and a clamping position. In the open position, the clamping leg is arranged spaced apart from the busbar, in particular from the clamping section of the busbar, and the conductor to be connected can be inserted into the intermediate space or conductor connection space thus formed between the busbar or the clamping section of the busbar and the clamping leg, or can be removed therefrom. In the clamping position, the clamping leg can abut against the busbar or the clamping section of the busbar, or against the connected conductor, in order to clamp the conductor on the wall of the busbar or the busbar through-hole (Strombalkendurchzug). The transfer of the clamping leg, in particular from the clamping position to the open position, is achieved by means of an operating element. The operating element is preferably guided linearly movable in the housing. Once the clamping leg reaches the open position by means of the operation of the operating element, the clamping leg engages with a triggering element, so that the clamping leg can be held in the open position by the triggering element, and thus the clamping leg can be prevented from accidentally swinging back from the open position to the clamping position. By means of the swinging movement of the triggering element, the clamping leg can be disengaged from the triggering element again, in order to pivot back to the clamping position and clamp the conductor to be connected on the busbar. The swinging movement of the triggering element can be triggered by the conductor to be connected itself, in such a way that when the conductor to be connected is inserted into the conductor connection space through the conductor insertion opening, the conductor strikes the triggering element and thereby triggers the tipping movement or pivoting movement of the triggering element. By means of the tipping movement or pivoting movement of the triggering element, the functional connection between the triggering element and the clamping leg of the clamping spring can be released, in such a way that the triggering element releases the clamping leg, so that the clamping leg can pivot automatically in the direction of the conductor to be connected by its spring force. In the case of conductors with a very small conductor cross-section, it may occur that insufficient pressure can be exerted on the triggering element by the conductor to trigger the triggering element and thus pivot it. Therefore, when the triggering cannot be achieved by the conductor itself, according to the setting of the present invention, an emergency triggering of the triggering element can be achieved by means of the operating element. For this purpose, the operating element has an operating arm, which interacts with the triggering element in order to trigger the triggering element when it has not been triggered by the conductor. Thus, by means of the operating arm of the operating element, the tipping movement or pivoting movement of the triggering element can be achieved in such a way that the clamping leg of the clamping spring can be disengaged from the triggering element and can thus pivot from the open position to the clamping position, in order to be able to clamp or connect the conductor inserted into the conductor connection space to the clamping section of the busbar. Thus, the conductor can be reliably and surely connected regardless of its conductor cross-section.
[0007] Preferably, in the open position of the clamping leg, the triggering element can engage with the clamping leg through a locking connection, such that the triggering element can be latched with the clamping leg in the open position. This locking connection enables the triggering element and the clamping leg to engage and disengage simply and easily.
[0008] To configure the above-mentioned latching, the clamping leg of the clamping spring can have at least one locking arm, which can be latched onto the triggering element in the open position. The at least one locking arm can extend out from the main extension plane of the clamping leg of the clamping spring, especially in the direction towards the retaining leg of the clamping spring. The locking arm can be blanked from the material of the clamping leg and bent into its shape. The locking arm can have the form of a tab, especially a spring tab. The locking arm can form a bent locking hook, which hooks onto the triggering element in the open position.
[0009] The triggering element can preferably be pivotally supported on the retaining leg of the clamping spring. Thus, the triggering element can be supported on the clamping spring made of metal and does not have to be supported on the housing made of plastic. The triggering element is preferably configured as a component independent of the clamping spring. The triggering element can be releasably fixed to the retaining leg of the clamping spring, especially releasably suspended on the retaining leg of the clamping spring. Then, the triggering element can pivot or tilt relative to the retaining leg of the clamping spring, which is preferably fixedly positioned in the housing. The retaining leg of the clamping spring can have a first leg and a second leg. The first leg can be used to support the retaining leg, and thus the clamping spring, in the housing. Through the first leg, the retaining leg can be connected to the arcuate section of the clamping spring. The first leg can then be arranged between the second leg and the arcuate section. The second leg of the retaining leg can extend angularly, especially at an angle of 90°, from the first leg. The triggering element can be supported on the second leg of the retaining leg, especially on the free end section of the second leg of the retaining leg. The free end section can be bent in the direction towards the clamping leg, such that the second leg of the retaining leg can have an L-shaped configuration.
[0010] The triggering element can be configured in the shape of a seesaw. The triggering element in the shape of a seesaw can preferably be releasably supported on the retaining leg of the clamping spring.
[0011] In order to construct a seesaw shape, the triggering element can have a first leg and a second leg connected to the first leg by a pivot bearing. The first leg can have a pressure surface through which the triggering element can be operated using a conductor. The second leg can cooperate with the operating arm of the operating element. The pivot bearing can define a swing axis about which the triggering element can pivot. In the region of its pivot bearing, the triggering element can be bent in a V-shape or a U-shape. Additionally, the pivot bearing can be a region of the triggering element on which the clamping leg latches with at least one of its locking arms in the open position and is thus held on the triggering element. The first leg and / or the second leg are preferably each constructed linearly. The triggering element can be constructed from a metal plate. Alternatively, it is also possible that the triggering element is constructed from a plastic material. The two legs of the triggering element extend out from the pivot bearing respectively. The two legs are used to trigger the triggering element, wherein the triggering element can be triggered using the conductor to be connected through the first leg, and the triggering element can be triggered using the operating arm of the operating element through the second leg. Whether the first leg is operated by the conductor to be connected or the second leg is operated by the operating element, a rotational movement or a tipping movement of the triggering element about the pivot bearing of the triggering element can be achieved. The pressure surface can be constructed on the first leg of the triggering element pointing in the direction of the conductor inlet opening. The pressure surface can define a conductor connection space downward in the direction of the inlet. The conductor to be connected can strike the pressure surface when inserted into the conductor connection space, whereby the triggering element can pivot along the inlet direction to disengage from the clamping leg, so that the clamping leg can be released and pivoted in the direction of the conductor to be connected to clamp the conductor on the busbar in the clamping position.
[0012] The triggering element can be swingably or tiltably supported on the holding leg of the clamping spring through its pivot bearing. The triggering element can place its pivot bearing on the holding leg, especially on the free end section of the second leg of the holding leg. The free end section of the second leg of the holding leg can then constitute a support position for the pivot bearing and thus for the triggering element.
[0013] On the second leg of the triggering element, a locking projection can be formed, which can cooperate with the operating arm of the operating element. In the case of an emergency trigger by the operating element, the locking projection can engage with the operating arm of the operating element, or the operating arm can at least partially surround or hook the locking projection from below. Through the locking projection, the operating arm of the operating element can tilt the second leg of the triggering element against the operating direction of the operating element to trigger the triggering element, and thus move the clamping leg out of the open position. Through the locking projection, the operating arm can apply a pulling force against the operating direction on the triggering element or on the second leg of the triggering element. The locking projection can be formed, in particular molded, on the longitudinal edge surface of the second leg of the triggering element. The locking projection can extend at a right angle from the longitudinal edge surface of the second leg of the triggering element inside the main extension plane of the second leg of the triggering element. Therefore, the second leg of the triggering element can have a greater width in the region of the locking projection than in the remaining region of the second leg. The operating arm can have a rear engagement portion, and the operating element can hook the locking projection from behind with this rear engagement portion to apply a pulling force to the triggering element. The rear engagement portion can extend transversely to the main extension plane of the operating arm. The rear engagement portion can be formed on the free end section of the operating arm, so that due to the molded rear engagement portion, the operating arm can have an L-shaped configuration.
[0014] The operating arm can be configured on the operating element such that the operating arm extends in the operating direction of the operating element, and the operating arm can laterally overlap with the operating section of the operating element for operating the clamping leg of the clamping spring. The operating arm can preferably extend linearly in the operating direction of the operating element. Therefore, the operating arm can form an extension of the operating element in the operating direction. In order for the operating arm not to interfere with the actual operation of the operating element on the clamping leg through the operating section of the operating element, the operating arm can pass by the operating section laterally, and thus laterally overlap with the operating section. The operating arm can generally have a bridge shape.
[0015] In order to be able to achieve a design that saves space as much as possible, a recess can be formed on the bus bar, and the operating arm can sink into the recess in the open position of the clamping leg of the clamping spring. The second leg of the triggering element can then be arranged with its locking projection as close as possible to the bus bar, especially the support section of the bus bar, without restricting the function of the operating arm of the operating element.
[0016] To simplify the manual operation of the emergency trigger for the user in particular, the operating element can have a release section on the upper side, and the operating element can be manually or with the aid of a tool pulled against the operating direction through this release section, where the release section preferably projects from the upper side of the operating element. Through this release section, a pulling force can be applied to the operating element manually or with the aid of a tool in a simple manner and method to trigger the triggering element.
[0017] Preferably, the release section may have at least one tool engagement section. A tool, such as a screwdriver, can then be reliably engaged with the tool engagement section in order to pull the operating element against the operating direction. The at least one tool engagement section may be configured in the form of a tab. In order to avoid skewing of the tool, the release section preferably may have two tool engagement sections, and the tool can then be engaged with the two tool engagement sections simultaneously. The two tool engagement sections may be configured in the form of tabs, for example, such that they can respectively form rear engagement portions for receiving the tool. The two tool engagement sections are preferably arranged eccentrically with respect to the upper side of the operating element such that they do not interfere with the operation of the operating element in the operating direction by means of the tool.
[0018] Furthermore, the solution to the task according to the invention can be achieved by means of a terminal, in particular a junction box, which may have at least one wiring device designed and improved as described above.
[0019] The wiring device configured and improved as described above can be part of a terminal, which can be configured as a junction box or a printed circuit board terminal, for example. The wiring device can also be used in a plug connector.
[0020] Especially when applied to a junction box that can be snapped onto a carrier rail, it is preferable to use two or more wiring devices configured and improved as described above. Description of the Drawings

[0026] Figure 4 Is shown in three dimensions Figure 3 A schematic view of the wiring device shown in Detailed Description of the Preferred Embodiments
[0027] In Figures 1 to 4Shown is a connection device 100 according to the present invention. The connection device 100 has a housing 110. The housing 110 can be constructed of an insulating material, such as a plastic material. The housing 110 has a conductor insertion opening 111 through which a conductor to be connected, not shown here, can be inserted into the housing 110 along an insertion direction E so as to be connectable to the connection device 100.
[0028] A busbar 112 and a clamping spring 113 are positioned in the housing 110. By means of the clamping spring 113, the conductor inserted into the housing 110 can be clamped onto the busbar 112 and thus connected. The busbar 112 has a clamping section 114 onto which the conductor to be connected can be clamped by means of the clamping spring 113 and thus connected. The busbar 112 also has a support section 115 which extends at an angle of 90° with respect to the clamping section 114.
[0029] The clamping spring 113 is configured as a torsion spring. The clamping spring 113 has a retaining leg 116 and a clamping leg 117. The clamping leg 117 is pivotable relative to the retaining leg 116 so as to transfer the clamping leg 117 into a clamping position and an open position. The clamping leg 117 has a clamping edge 118 at its free end section. In the clamping position of the clamping leg 117, the clamping edge clamps the conductor L to be connected onto the clamping section 114 of the busbar 112.
[0030] Viewed along the insertion direction E of the conductor L, the conductor connection space formed between the clamping section 114 of the busbar 112 and the clamping leg 117 of the clamping spring 113 is limited downward by a triggering element 119. The triggering element 119 is releasably connected to the clamping spring 113, in particular swingably or tiltably supported on the clamping spring 113.
[0031] The triggering element 119 has a pressure surface 120 pointing in the direction of the conductor insertion opening 111 against which the conductor L can strike when inserted into the conductor connection space. If the conductor L strikes the pressure surface 120, a pivoting movement or tilting movement V of the triggering element 119 along the insertion direction E is triggered.
[0032] The triggering element 119 can be stamped from a metal sheet and bent into a corresponding shape. Thus, the triggering element 119 can be a stamped and bent part. However, it is also possible that the triggering element 119 is constructed of a plastic material.
[0033] The trigger element 119 is configured in the shape of a seesaw. The trigger element 119 has a first leg 121 and a second leg 122, wherein the first leg 121 and the second leg 122 are connected by a pivot bearing 123. In the design shown here, the trigger element 119 is configured substantially symmetrically such that the first leg 121 and the second leg 122 have approximately the same length and thus extend the same distance from the pivot bearing 123. In addition, the pivot bearing 123 is thus configured at the middle position of the length of the trigger element 119. The first leg 121 and the second leg 122 are each configured linearly. However, it is also possible that the first leg 121 and the second leg 122 are configured asymmetrically with respect to each other and can thus have different lengths from each other.
[0034] The pivot bearing 123 of the trigger element 119 has a V-shaped or U-shaped form. By means of the pivot bearing 123, the trigger element 119 is pivotably or tiltably supported on the holding leg 116 of the clamping spring 113.
[0035] The pressure surface 120 is configured on the first leg 121 of the trigger element 119. Thus, when viewed along the insertion direction E, the first leg 121 of the trigger element 119 can delimit the conductor connection space downwards.
[0036] The holding leg 116 of the clamping spring 113 has a first leg 124 and a second leg 125 arranged at an angle with respect to the first leg 124. The trigger element 119 is tiltably supported on the second leg 125 of the holding leg 116.
[0037] In the design shown here, the first leg 124 of the holding leg 116 enables the clamping spring 113 to be supported on the inner wall 126 of the housing 110, as can be seen in the cross-sectional views of Figure 1 and Figure 3 Alternatively, it is also possible that the first leg 124 of the holding leg 116 is supported on the busbar 112. The first leg 124 adjoins the arcuate section 127 of the clamping spring 113 by means of which the holding leg 116 is connected to the clamping leg 117 of the clamping spring 113. The first leg 124 of the holding leg 116 is arranged between the arcuate section 127 and the second leg 125 of the holding leg 116.
[0038] In the design shown here, the second leg 125 extends from the first leg 124 at an angle of approximately 90°. However, the angle between the first leg 124 and the second leg 125 can also be less than 90°, for example. The second leg 125 extends here substantially parallel to the support section 115 of the busbar 112. The second leg 125 has a bent free end section 128. The trigger element 119 is supported on this free end section 128 by its pivot bearing 123. The free end section 128 is bent in the direction of the clamping leg 117 of the clamping spring 113. Due to the bent free end section 128, the second leg 125 has an L-shaped shape.
[0039] The trigger element 119 is placed on the free end section 128 by its pivot bearing 123 in such a way that the trigger element 119 can tilt to the right and left like a seesaw.
[0040] In the open position of the clamping leg 117 of the clamping spring 113, the clamping leg 117 engages with the trigger element 119 in order to hold the clamping leg 117 in the open position. This is achieved by a latching between the trigger element 119 and the clamping leg 117.
[0041] In the design shown here, the clamping leg 117 has a locking arm 129 for this purpose, which latches in the open position, in particular in the region of the pivot bearing 123 on the trigger element 119, as can be seen in Figure 1 and Figure 2 The locking arm 129 extends from the main extension plane of the clamping leg 117 of the clamping spring 113, in particular in the direction of the holding leg 116 of the clamping spring 113. In the design shown here, the locking arm 129 is blanked out from the material of the clamping leg 117 and bent into its shape. The locking arm 129 has the shape of a tab, in particular the shape of a spring tab or a locking tab.
[0042] In the open position of the clamping leg 117 of the clamping spring 113, the locking arm 129 hooks into or latches in the trigger element 119 in the region of the pivot bearing 123 of the trigger element 119. In the open position, the locking arm 129 hooks behind the pivot bearing 123 in such a way that the locking arm 129 overlaps the pivot bearing 123 and hooks onto the pivot bearing 123.
[0043] Figure 1 and Figure 2 show the clamping leg 117 of the clamping spring 113 in the open position, in which the clamping leg 117 engages with the trigger element 119 by means of its locking arm 129 and thereby releases the conductor connection space so that the conductor to be connected can be inserted into the conductor connection space along the insertion direction E through the conductor insertion opening 111.
[0044] When the conductor to be connected is inserted into the conductor connection space along the insertion direction E, the conductor to be connected strikes the pressure surface 120 of the trigger element 119. Thereby, a tilting movement or pivoting movement V of the trigger element 119 along the insertion direction E is achieved, whereby the locking arm 129 is disengaged from the trigger element 119 or the rotational bearing portion 123 of the trigger element 119. The clamping leg 117 is thereby released, whereby the clamping leg 117 can pivot away from the trigger element 119 or the holding leg 116 automatically by its restoring force or its spring force, in the direction of the conductor inserted into the conductor connection space, in order to be able to clamp the conductor onto the clamping section 114 of the busbar 112.
[0045] If the conductor is to be loosened again from the clamped position, the operating element 139 is moved along the operating direction B inside the operating recess 140 of the housing 110. By the displacement movement of the operating element 139 along the operating direction B, the operating element 139 presses the clamping leg 117 away from the conductor with its operating section 141, so that the clamping leg 117 pivots in the direction of the holding leg 116. The operating element 139 exerts a pressure on the clamping leg 117 along the operating direction B such that the clamping leg 117 moves in the direction of the holding leg 116 so far until the clamping leg 117 engages with the trigger element 119 via its locking arm 129 and is thus in the open position and held there. The operating element 139 is linearly movably supported in the operating recess 140 of the housing 110.
[0046] In the design shown here, the unlocking of the locking between the locking arm 129 of the clamping leg 117 of the clamping spring 113 and the trigger element 119 can be achieved not only by the conductor to be connected, but also by operating the operating element 139. For this purpose, the operating element 139 has an operating arm 142. When the trigger element 119 is not triggered by the conductor to be connected, the operating arm 142 of the operating element 139 can cooperate with the trigger element 119 such that the locking arm 129 of the clamping leg 117 is disengaged from the trigger element 119 and the clamping leg can be pivoted from the open position into the clamped position.
[0047] As in Figure 2 and Figure 4As can be seen in, the operating arm 142 extends in the operating direction B of the operating element 139. The operating arm 142 forms an extension, in particular a lateral extension, of the operating element 139. The operating arm 142 is positioned such that it laterally overlaps the operating section 141 of the operating element 139. The operating arm 142 is constructed in a bridge shape. The operating arm 142 is constructed to be so long that it laterally overlaps the clamping leg 117 and the locking arm 129 of the clamping leg 117. The operating arm 142 also laterally overlaps the triggering element 119. In the open position of the clamping leg 117 of the clamping spring 113, the operating arm 142 sinks into the recess 143 on the busbar 112, in particular into the recess 143 on the support section 115 of the busbar 112, as in Figure 2 as can be seen in.
[0048] The operating arm 142 is constructed in an L-shape here and has a rear engagement part 144 at its free end. Through this rear engagement part 144, the operating arm 142 can cooperate with the locking projection 130 constructed on the second leg 122 of the triggering element 119. In the case of an emergency trigger by the operating element 139, the locking projection 130 can hook onto the operating arm 142 of the operating element 139, in particular onto the rear engagement part 144 of the operating arm 142, or the operating arm 142 can at least partially surround or hook under the locking projection 130 from below, as in Figure 4 as can be seen in. Through the locking projection 130, the operating arm 142 of the operating element 139 can tip the second leg 122 of the triggering element 119 against the operating direction B of the operating element 139 (tipping movement V) in order to trigger the triggering element 119 and thus release the clamping leg 117 from the open position.
[0049] Through the locking projection 130, the operating arm 142 can apply a pulling force Z against the operating direction B to the triggering element 119 or to the second leg 122 of the triggering element 119. Therefore, if the tipping movement V of the triggering element 119 cannot be triggered by the conductor to be connected, it can also be achieved by means of the operating element 139.
[0050] The locking projection 130 is constructed, in particular molded, on the longitudinal edge surface 131 of the second leg 122 of the triggering element 119. The locking projection 130 extends at a right angle from the longitudinal edge surface 131 of the second leg 122 of the triggering element 119 inside the main extension plane of the second leg 122 of the triggering element 119. Therefore, the second leg 122 of the triggering element 119 has a greater width in the region of the locking projection 130 than in the remaining region of the second leg 122.
[0051] To simplify manual operation, the operating element 139 has a release section 146 on its upper side 145. The release section 146 projects from the upper side 145 of the operating element 139. By means of the release section 146, a tensile force Z can be applied to the operating element 139 manually or with the aid of a tool W in a simple manner. The release section 146 is configured eccentrically on the operating element 139 with respect to the upper side 145 of the operating element 139.
[0052] In the design shown here, the release section 146 has two tool engagement sections 147a, 147b. As Figure 3 and Figure 4 shown, a tool W, such as a screwdriver, can engage in these two tool engagement sections 147a, 147b in order to apply a tensile force Z to the operating element 139 and thus pull the operating element 139 against the operating direction B. The two tool engagement sections 147a, 147b are each configured in the form of tabs such that they can each form a rear engagement portion for receiving the tool W.
