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 usually has a clamping spring configured as a helical torsion spring, which has a holding 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 then operated so that the clamping spring or the clamping leg pivots away from the busbar, whereby 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 in order to be able to pivot the clamping leg 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. In order 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. The above-mentioned manual operation of the operating element makes the assembly or wiring of the conductor difficult for the user because the operation 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 flexible conductors in particular can be simplified.
[0004] According to the present invention, this object is solved by the features of the independent claims. Suitable designs and advantageous developments 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, the clamping spring having a holding leg and a clamping leg, wherein the clamping leg is transferable 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 the triggering element is pivotably supported on the clamping spring in such a way that, when a conductor to be connected is inserted into the conductor insertion opening in the insertion direction, the triggering element can be operated via the pressure surface of 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 invention, flexible conductors can also be simply and reliably connected and clamped to the busbar. The clamping spring is preferably configured as a helical torsion spring, which has a retaining leg and a clamping leg pivotally configured relative to the retaining leg. By the pivoting movement of the clamping leg of the clamping spring, the clamping leg can be transferred into 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 bear against the busbar or the clamping section of the busbar, or against the connected conductor, in order to clamp the conductor to the busbar or the clamping section of the busbar. The transfer of the clamping leg, in particular from the clamping position to the open position, is effected by means of an operating element. The operating element is preferably guided in the housing so as to be able to move purely linearly. As long as the clamping leg reaches the open position by operating the operating element, the clamping leg engages with the 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 undesirably swinging back from the open position into the clamping position. The triggering element and the clamping spring can form a closed force system in the open position of the clamping leg. If the open position of the clamping leg is reached, then, therefore, the operating element can be moved again away from the clamping leg of the clamping spring against the operating direction of the operating element, at which time the clamping leg does not follow the operating element. Thus, in the open position itself, the operating element can be positioned spaced apart from the clamping leg of the clamping spring. If the clamping leg is held in the open position by the triggering element, the operating element can be moved again back to its initial position against the operating direction, so that in the open position of the clamping leg, no effective connection is formed between the operating element and the clamping leg. By the pivoting movement of the triggering element, the clamping leg can be disengaged from the triggering element again, so that the clamping leg pivots back into the clamping position and clamps the conductor to be connected to the busbar. The pivoting 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 in the region of the pressure surface of the triggering element, and thus triggers the tipping movement or pivoting movement of the triggering element. By the tipping movement or pivoting movement of the triggering element, the effective connection between the triggering element and the clamping leg of the clamping spring can then 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.
[0007] Preferably, the triggering element can be engaged with the clamping leg by a latching connection in the open position of the clamping leg, so that the triggering element can be latched with the clamping leg in the open position. This latching connection enables the triggering element and the clamping leg to be simply and easily engaged and disengaged. During the transfer of the clamping leg from the clamping position to the open position, by the pushing force of the operating element along the operating direction, the clamping leg can pivot in the direction of the holding leg so far that the clamping leg can be latched on the triggering element.
[0008] To construct this latching, at least one protrusion can be constructed on the clamping leg and arranged on the longitudinal edge surface of the clamping leg. This protrusion can be latched on the undercut of the triggering element in the open position of the clamping leg of the clamping spring. When the clamping leg pivots from the clamping position to the open position, the clamping leg can move with its at least one protrusion in the direction of the holding leg so far that the clamping leg can hook its at least one protrusion into at least one undercut constructed on the triggering element or be latched there. Preferably, the clamping leg has protrusions on its two opposite longitudinal edge surfaces respectively, and the triggering element preferably also has two oppositely arranged undercuts, so that the clamping leg can be latched on the triggering element through its two longitudinal edge surfaces. This can achieve the anti-tipping support of the clamping leg on the triggering element in the open position of the clamping leg. At least one protrusion is preferably constructed on the clamping leg at a distance from the clamping edge of the clamping leg. For example, at least one protrusion can be approximately constructed at the middle position of the length of the clamping leg on the clamping leg. At least one protrusion can extend out from the longitudinal edge surface of the clamping leg transversely to the longitudinal extension of the clamping leg.
[0009] The triggering element can preferably be pivotally supported on the holding leg of the clamping spring. Therefore, the triggering element can be supported on the metal part of the clamping spring without having to be supported on the plastic part of the housing. The triggering element is preferably constructed as a component independent of the clamping spring. The triggering element can be detachably fixed on the holding leg of the clamping spring, especially detachably hooked and / or clipped on the holding leg. The triggering element can then pivot relative to the holding leg of the clamping spring that is fixedly positioned in the housing. When assembling the wiring device, the triggering element can be pre-assembled on the clamping spring and positioned in the wiring device as a unit. In the assembled state, the triggering element and the clamping spring can form a pre-tensioned unit. This can prevent the pre-tension force from acting on the housing of the wiring device.
[0010] In order to be able to pivotally support the trigger element on the holding leg, a bolt can be constructed on at least one longitudinal edge surface of the holding leg, and this bolt can engage into an opening constructed on the trigger element. This enables the trigger element to be simply assembled on the clamping spring. At least one bolt can form a pivot axis about which the trigger element can pivot. Preferably, the holding leg has two oppositely arranged bolts, so that bolts are respectively constructed on two oppositely arranged longitudinal edge surfaces of the holding leg. The trigger element preferably also has two oppositely arranged openings, and each of the bolts can respectively engage into the openings. This enables anti-tipping rotational support of the trigger element on the holding leg of the clamping spring. These bolts preferably extend out from the corresponding longitudinal edge surfaces of the holding leg transversely to the longitudinal extension of the holding leg.
[0011] The trigger element can be constructed such that it can have a base body constructed in a U-shape, which has a first side wall and a second side wall oppositely arranged thereto. These two side walls can laterally define a conductor connection space. These two side walls can form guiding surfaces for the conductors to be connected when the conductors are inserted into the conductor connection space. Viewed along the insertion direction, these two side walls can be constructed to be so long that these side walls start to extend from the wall defining the conductor insertion opening of the housing and thus form a continuous guiding portion of the wall of the housing. Therefore, incorrect insertion of the conductors to be connected can be prevented by the two side walls of the trigger element.
[0012] The base body can have a connecting wall extending transversely to the insertion direction, which is used to connect the first side wall and the second side wall, and a pressure surface can be constructed on the connecting wall. The connecting wall preferably extends transversely to the insertion direction. The connecting wall can limit the conductor connection space downward along the insertion direction. Therefore, when the conductor is inserted into the conductor connection space, the conductor can purposefully impact on the pressure surface so as to pivot the trigger element and thus release the clamping leg, whereby the clamping leg can automatically pivot from the open position to the clamping position by its spring force.
[0013] On the base body, at least one holding arm extending substantially transversely to the insertion direction can be formed, and the triggering element can be swingably supported on the clamping spring via this holding arm. Thus, the swingable support of the triggering element can be configured at a distance from the base body or the side wall of the base body. At least one holding arm can start from one of the side walls of the base body and extend in the direction of the holding leg of the clamping spring. Openings can be formed in at least one holding arm, and at least one bolt of the holding leg of the clamping spring can be hooked or engaged into the openings. Preferably, the triggering element has two holding arms extending substantially parallel to each other. Then, the first holding arm can start from the first side wall and extend in the direction of the holding leg, and the second holding arm can start from the second side wall and extend in the direction of the holding leg. Openings can then be formed in both holding arms respectively, and the respective bolts of the holding leg can be engaged into the openings respectively, so as to swingably support the triggering element on the holding leg of the clamping spring via the two holding arms.
[0014] In addition, it is possible that the clamping spring has spring legs, and the spring legs can cooperate with the triggering element in such a way that in the clamping position of the clamping leg of the clamping spring, the triggering element is pre-tensioned. The spring legs are preferably arranged and configured such that the spring legs press against the triggering element with their spring force against the insertion direction. Viewed along the insertion direction, the spring legs cooperate with the triggering element below the pressure surface. For this purpose, the spring legs can apply a pushing force to the triggering element against the connecting wall below the conductor connection space. When connecting the conductor, by applying a pushing force on the pressure surface with the aid of the conductor, the spring legs are deflected along the insertion direction and thus tensioned. Thereby, the triggering element is pre-tensioned by the spring legs in the clamping position. If the conductor is to be loosened again from the clamping position and thus from the wiring device, then the spring legs can swing the triggering element back against the insertion direction into its initial position again, so that the triggering element can engage with the clamping leg in order to hold the clamping leg in the open position. Thus, the spring legs can act as a reset element for the triggering element. In addition, by means of the spring legs, the triggering element can be clamped on the clamping spring in the open position, whereby the triggering element and the clamping spring can form a pre-tensioned unit in order to be able to be assembled together in the wiring device and especially on the busbar.
[0015] The spring legs are preferably configured such that the spring legs can start from the holding leg of the clamping spring and extend substantially transversely to the insertion direction.
[0016] The clamping spring can be hung on the busbar. Thus, the clamping spring together with the trigger element swingably supported on the clamping spring can be hung on the busbar as a pre-assembled unit. Thereby, the support of the clamping spring and / or the trigger element on the housing can be minimized as much as possible. The clamping spring can be hung on the busbar by its holding leg, in such a way that through holes are formed in the holding leg, and the clamping section of the busbar can be inserted into the through holes, so that the clamping section of the busbar can extend through the through holes in the holding leg of the clamping spring.
[0017] Furthermore, the object of the present invention can be solved by means of a terminal block, in particular a junction box, which can have at least a wiring device designed and improved as described above.
[0018] The wiring device designed and improved as described above can be part of a terminal block, which can be constructed, for example, as a junction box or a printed circuit board terminal block. The wiring device can also be used in a plug connector.
[0019] In particular, when used in a junction box that can be snapped onto a support rail, it is preferably possible to use two or more wiring devices constructed and improved as described above. Description of the Drawings
[0020] The present invention will be described in detail below with reference to the drawings according to preferred embodiments.
[0021] Wherein:
[0022] Figure 1A 、 1B shows a schematic view or a cross-sectional view of the wiring device according to the present invention, wherein the clamping legs of the clamping spring are in the open position, and
[0023] Figure 2A 、 2B shows Figure 1A 、 1B a schematic cross-sectional view of the wiring device shown in when a conductor is connected, wherein the clamping legs of the clamping spring are in the clamping position.
[0024] In Figure 1A 、 1B and Figure 2A 、 2B a wiring device 100 according to the present invention is shown. The wiring device 100 includes a housing 110. The housing 110 can be constructed of an insulating material, for example, a plastic material. The housing 110 has a conductor inlet opening 111, and the conductor L to be connected can be inserted into the housing 110 through the conductor inlet opening along the inlet direction E so as to be connectable to the wiring device 100.
[0025] A busbar 112 and a clamping spring 113 are positioned in the housing 110. By means of the clamping spring 113, a conductor L inserted into the housing 110 can be clamped onto the busbar 112 and thus be wired. The busbar 112 has a clamping section 114 onto which the conductor L to be connected can be clamped by means of the clamping spring 113 and thus be wired. The busbar 112 also has a support section 115 which extends at an angle of 90° relative to the clamping section 114.
[0026] The clamping spring 113 is configured as a helical 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 move 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, which clamping edge is visible in the Figure 1B and Figure 2B cross-sectional view, and which clamping edge clamps the conductor L to be connected onto the clamping section 114 of the busbar 112 in the clamping position of the clamping leg 117.
[0027] Viewed along the insertion direction E of the conductor L, a conductor connection space 150 formed between the clamping section 114 of the busbar 112 and the clamping leg 117 of the clamping spring 113 is defined downward by a pressure surface 120 of a triggering element 119. The triggering element 119 is detachably connected to the clamping spring 113, in particular pivotally supported on the clamping spring 113.
[0028] The triggering element 119 has a pressure surface 120 facing the direction of the conductor insertion opening 111, against which the conductor L impinges when inserted into the conductor connection space 150. If the conductor L impinges on the pressure surface 120, a pivoting movement or tipping movement V of the triggering element 119 along the insertion direction E is triggered, as depicted in Figure 2A 、 2B 。
[0029] The triggering element 119 has a base body 121 configured in a U-shape, which has two side walls 122A, 122B extending parallel to each other, and a connecting wall 123 connecting the two side walls 122A, 122B to each other. The two side walls 122A, 122B extend in the insertion direction E. The connecting wall 123 extends transversely to the insertion direction E. A pressure surface 120 pointing in the direction of the conductor insertion opening 111 is configured on the connecting wall 123. The connecting wall 123 delimits a conductor connection space 150 downward along the insertion direction E. The two side walls 122A, 122B laterally delimit the conductor connection space 150, so that the conductor L to be connected can be prevented from being incorrectly inserted. The two side walls 122A, 122B form a lateral guiding portion for the conductor L to be connected in the direction towards the pressure surface 120. The side walls 122A, 122B are adjacent to the wall 124 of the housing 110 that delimits the conductor insertion opening 111, and starting from the wall 124, extend to the connecting wall 123 that delimits the conductor connection space 150 downward. Therefore, after the conductor L to be connected leaves the conductor insertion opening 111, it is directly laterally guided by the side walls 122A, 122B over the entire length of the conductor connection space 150 up to the pressure surface 120.
[0030] Furthermore, the triggering element 119 has two holding arms 125A, 125B that extend substantially parallel to each other. The first holding arm 125A starts from the first side wall 122A and extends towards the holding leg 116 of the clamping spring 113, and the second holding arm 125B starts from the second side wall 122B and extends towards the holding leg 116 of the clamping spring 113. The two holding arms 125A, 125B start from the two side walls 122A, 122B and extend substantially transversely to the insertion direction E.
[0031] In particular Figure 1A and Figure 1BShows the case where the clamping legs 117 of the clamping spring 113 are in the open position. In the open position, the triggering element 119 engages with the clamping legs 117 of the clamping spring 113 to hold the clamping legs 117 in the open position. This is achieved by a latching between the triggering element 119 and the clamping legs 117. To construct this latching, in the design shown here, the clamping legs 117 of the clamping spring 113 each have protrusions 127A, 127B on their two longitudinal edge surfaces 126. The protrusions 127A, 127B extend at a right angle from the respective longitudinal edge surfaces 126. In addition, the triggering element 119 has two oppositely configured undercuts 128A, 128B, and in the open position of the clamping legs 117, the two protrusions 127A, 127B of the clamping legs 117 can be hooked or latched into the undercuts respectively. The two undercuts 128A, 128B each have the shape of a recess. The two undercuts 128A, 128B are constructed on the two holding arms 125A, 125B of the triggering element 119, so the first undercut 128A is constructed on the first holding arm 125A, and the second undercut 128B is constructed on the second holding arm 125B. The two protrusions 127A, 127B are constructed at a distance from the clamping edge 118 such that the clamping legs 117 are not just latched or held in position by their clamping edge 118 in the open position.
[0032] The triggering element 119 is constructed as an independent component relative to the clamping spring 113, and the triggering element 119 is detachably fixed to the clamping spring 113. The triggering element 119 is swingably supported on the holding legs 116 of the clamping spring 113 by its two holding arms 125A, 125B. The triggering element 119 can pivot relative to the position-fixed holding legs 116.
[0033] To construct the pivotable support, in the design shown here, the holding legs 116 each have pins 130 on their two oppositely arranged longitudinal edge surfaces 129 (only one longitudinal edge surface is visible here). Openings 131A, 131B are respectively constructed on the two holding arms 125A, 125B of the triggering element 119, and each of the two pins 130 engages into the openings. The two pins 130 form the swing axis of the triggering element 119, and the triggering element 119 can swing around this swing axis. These pins 130 extend from the respective longitudinal edge surfaces 129 of the holding legs 116 transversely to the longitudinal extension of the holding legs 116.
[0034] Figure 1A 、 1BShows the case where the clamping legs 117 of the clamping spring 113 are in the open position, in which the clamping legs 117 engage with the trigger element 119, and thereby release the conductor connection space 150, so that the conductor L to be connected can be inserted into the conductor connection space 150 through the conductor insertion opening 111.
[0035] As can be seen in Figure 2A 、 2B When the conductor L to be connected is inserted into the conductor connection space along the insertion direction E, the conductor L to be connected hits 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 two protrusions 127A, 127B of the clamping legs 117 can be decoupled from the two undercuts 128A, 128B of the trigger element 119. Thereby, the clamping legs 117 are disengaged from the trigger element 119, so that the clamping legs 117 can automatically swing away from the trigger element 119 or the holding leg 116 by their restoring force or their spring force, and pivot towards the conductor L inserted into the conductor connection space 150, so as to be able to clamp the conductor L on the clamping section 114 of the bus bar 112, as shown in Figure 2A 、 2B as shown in.
[0036] If the conductor L is to be loosened again from the clamped position, the operating element 139 is moved along the operating direction B by means of a tool W inside the operating recess 140 of the housing 110, as shown in Figure 1A 、 1B as shown in. By the displacement movement of the operating element 139, the operating element 139 presses on the clamping legs 117 with its operating section 141, so that they are moved away from the conductor L or the clamping section 114 of the bus bar 112, thereby causing the clamping legs 117 to pivot towards the holding leg 116. The operating element 139 exerts a pushing force along the operating direction B on the clamping legs 117, causing the clamping legs 117 to move towards the holding leg 116 so far until the clamping legs 117 are re-engaged with the trigger element 119 and thus are in the open position and held there. The operating element 139 is linearly movably supported in the operating recess 140 of the housing 110.
[0037] In order that when the conductor L is loosened, the trigger element 119 also pivots back again to its (as in Figure 1A and Figure 1BIn the initial position (as shown in [reference]), the clamping spring 113 has spring legs 136 that act as a reset element. The spring legs 136 are constructed on the holding legs 116. When observed along the insertion direction E, the spring legs 136 cooperate with the trigger element 119 below the pressure surface 120. The spring legs 136 apply a pushing force to the trigger element 119 against the connecting wall 123 below the conductor connection space 150. When wiring the conductor L, by applying a pushing force on the pressure surface 120 with the conductor L, the spring legs 136 are deflected along the insertion direction E and thus tensioned. Thereby, the trigger element 119 is pre-tensioned by the spring legs 136 in the clamping position, as shown in Figure 2A , 2B . If the conductor L is to be released again from the clamping position and thus from the wiring device 100, the spring legs 136 can swing the trigger element 119 back against the insertion direction E to its initial position. Thereby, the trigger element 119 can engage with the clamping legs 117 through its two undercuts 128A, 128B to hold the clamping legs in the open position. In the open position, the engagement of the spring legs 136 and the protrusions 127A, 127B of the clamping legs 117 into the undercuts 128A, 128B of the trigger element 119 can also be used to achieve the clamping of the trigger element 119 and the clamping spring 113. Thereby, the trigger element 119 and the clamping spring 113 can form a pre-tensioned unit so as to be assembled together in the wiring device 100, and in particular on the bus bar 112.
[0038] In the design shown here, the holding leg 116 has a first section 132, a second section 133, and a third section 134. These sections 132, 133, 134 are respectively constructed at an angle to each other. A pin 130 is constructed on the first section 132 to swingably hold the trigger element 119 on the holding leg 116. The first section 132 extends at an angle of approximately between 20° and 70° relative to the insertion direction E. The second section 133 adjoins the first section 132. The second section 133 extends substantially transversely to the insertion direction E. The clamping spring 113 has the second section 133 located on the support section 115 of the bus bar 112. The spring legs 136 are punched out from the second section 133 such that the spring legs 136 can bounce relative to the second section 133. In addition, a through hole 135 is constructed on the second section 133, and the bus bar 112 guides through the through hole with its clamping section 114. Thereby, the clamping spring 113 can be hung on the bus bar 112. With the third section 134 that adjoins the second section 133 and extends in the insertion direction E, the holding leg 116 lies flat against the clamping section 114 of the bus bar 112.
[0039] The operating element 139 has a latching projection 142. Viewed in the operating direction B, the latching projection 142 is arranged on the operating element 139 above the operating section 141. In the open position, the latching projection 142 latches onto the lower edge surface 143 of the operating recess 140 of the housing 110, such that the operating element 139 remains sunken in the operating recess 140 in the open position, so that the open position can be indicated to the user by the position of the operating element 139. If, when operating the triggering element 119 by means of the conductor L, the clamping leg 117 is released from its latching engagement with the triggering element 119, the clamping leg 117 presses against the operating element 139 by its spring force and the operating element becomes disengaged from its latching engagement with the housing 110, such that the operating element 139 moves upwards against the operating direction B until the upper side 145 of the operating element 139, which has the tool engagement portion 144, is positioned flush with the outer surface 146 of the housing 110, as can be seen in Figure 2A and 2B . Thus, in the clamping position of the clamping leg 117, the operating element 139 terminates flush with the outer surface 146 of the housing 110 with its upper side 145. In this position, the latching projection 142 of the operating element 139 can latch into a cut-out provided in the operating recess 140 of the housing 110 in order to hold and latch the operating element 139 in this position.
