Abstract
Description
Field of the Invention
[0001] The invention relates to a connection device for connecting electrical conductors. The invention further relates to a terminal, in particular a junction box, having such a connection device. Background Art
[0002] Such a connection device usually has a clamping spring configured as a helical torsion spring, which has a retaining leg and a clamping leg. A conductor inserted into the connection 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 the open position by means of an operating element before the conductor is inserted and then be 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 so that the clamping leg can 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. 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 invention is to provide a connection device in which the wiring of flexible conductors in particular can be simplified.
[0004] According to the invention, this object is solved by the features of the independent claims. Suitable designs and advantageous developments of the 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 retaining leg and a clamping leg, wherein the clamping leg is transferable to 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 to the open position. In addition, the connection device has a triggering element which, in the open position of the clamping leg, engages with the clamping leg such that the clamping leg is held in the open position by means of the triggering element, and which can be swung such that when a conductor to be connected is inserted into the conductor insertion opening in the insertion direction, the triggering element can be operated such that the clamping leg disengages from the triggering element and pivots from the open position to the clamping position.
[0006] Now, with the aid of 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 wall of the busbar or the busbar through-passage. 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 in a purely linear manner. As long as the clamping leg reaches the open position by means of the operation of 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, furthermore, the clamping leg can be prevented from undesirably swinging back into the clamping position from the open 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 needs to be constructed between the operating element and the clamping leg any more. By the swinging movement of the triggering element, the clamping leg can be disengaged from the triggering element again, so that the clamping leg swings 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 via the conductor inlet opening, the conductor strikes 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 trigger element can be engaged with the clamping leg in the open position of the clamping leg by a latching connection, so that the trigger element can be latched with the clamping leg in the open position. This latching connection enables the trigger element and the clamping leg to be simply and easily engaged and disengaged. The latching connection can be configured such that the trigger element and the clamping leg of the clamping spring are hooked in the open position.
[0008] To form such a latch, the trigger element can have at least one locking arm, which can be latched on the clamping leg of the clamping spring in the open position. In the open position, the at least one locking arm can be hooked into the clamping leg. The at least one locking arm can extend out from the main extension plane of the trigger element, especially in the direction of the clamping leg of the clamping spring. The at least one locking arm can extend out from the main extension plane of the trigger element at an angle of approximately 90°, for example, or be bent out from the main extension plane at an angle of approximately 90°. The at least one locking arm can be configured in a tabular shape and extend out tongue-like from the main extension plane of the trigger element. The at least one locking arm can be configured or bent into a hook shape. At least one cutout can be formed on the clamping leg, and in the open position of the clamping leg, the at least one locking arm can be engaged into the cutout. The at least one locking arm can sink through the cutout and be latched or rear-hooked on the edge surface defining the cutout. The cutout can be configured in a window shape on the clamping leg. It is also possible to make the trigger element have two locking arms, and the holding leg have two cutouts, so that each locking arm can sink into a cutout and be latched or rear-hooked there.
[0009] The at least one locking arm can be sheared from the material of the trigger element and be configured to bend in the direction of the clamping leg. If only one locking arm is provided, the locking arm can be blanked from the material of the trigger element in the middle of the width of the trigger element and bend out from the main extension plane of the trigger element in the direction of the clamping leg of the clamping spring. If the at least one locking arm is blanked from the material of the trigger element and bent out from the main extension plane, in the blanked area, the trigger element has an opening, especially a window-shaped opening. Through this opening, the trigger element can be weakened purposefully in this area, thereby improving the spring characteristics of the trigger element and thus reducing the force consumption required to trigger the trigger element.
[0010] The triggering element can preferably be pivotally supported on the holding leg of the clamping spring. Thus, the triggering element can be supported on the metal part of the clamping spring without having to be supported on or braced against the plastic part of the housing. The triggering element is preferably configured as a component independent of the clamping spring. The triggering element can be detachably fixed to the holding leg of the clamping spring, in particular detachably hooked and / or clipped onto 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.
[0011] In order to be able to pivotally support the triggering element on the holding leg, the triggering element can engage in at least one cutout formed in the holding leg. The triggering element can be inserted into the cutout of the holding leg. The triggering element preferably inserts into the cutout with a free end section. The free end section can be configured tongue-shaped. The cutout can be configured window-shaped in the holding leg of the clamping spring.
[0012] In order to support the triggering element on the clamping spring, it can also be provided that the triggering element has an opening into which the holding leg of the clamping spring can be inserted. The holding leg can sink with its free end into the opening on the triggering element in order to hold the clamping spring on the triggering element. Together with the triggering element sinking into the cutout formed in the holding leg, the above method enables an anti-tipping support of the triggering element on the holding leg. The opening can be configured window-shaped on the triggering element.
[0013] When the triggering element is supported on the holding leg of the clamping spring in such a way that the clamping leg of the clamping spring is in engagement with the triggering element in its open position, a mutual holding of the triggering element and the clamping spring can be formed. In addition, this enables the triggering element and the clamping spring to form a pre-tensioned unit so that the clamping spring and the triggering element can be assembled as a pre-tensioned unit into the wiring device, in particular onto the busbar of the wiring device.
[0014] The triggering element can have a triggering leg on which a pressure surface is formed, by means of which the triggering element can be operated with a conductor. The pressure surface can point in the direction of the conductor insertion opening. The pressure surface can delimit a conductor connection space downward along the insertion direction. The conductor to be connected can strike against the pressure surface when inserted into the conductor connection space, whereby the triggering element can pivot in the insertion direction in order 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 in order to clamp the conductor onto the busbar in the clamping position. The pressure surface is preferably configured at a distance from at least one locking arm and / or at a distance from the free end section of the triggering element, with which the triggering element engages in the cutout of the holding leg.
[0015] The operating element may have an operating section which, when operating the clamping leg, can form an effective connection with the clamping leg. A recess may be formed on the operating section, and at least one locking arm of the triggering element can sink into the recess when the clamping leg is transferred from the clamping position to the open position. The recess may be formed as a concave portion on the operating section. The recess may be large enough for at least one locking arm to sink into it. The recess enables the clamping leg to be operated by the operating element without hindrance so that the clamping leg is transferred to the open position in such a way that the clamping leg can engage with the triggering element.
[0016] To prevent incorrect insertion of the conductor during conductor connection, the busbar may have a guide wall for the conductor to be connected. Through this guide wall, the conductor to be connected can be reliably guided to the triggering element, or rather to the pressure surface of the triggering element. The guide wall may be constructed to be long enough so that it can extend from the wall of the housing that defines the conductor inlet opening of the housing to the pressure surface of the triggering element. The conductor connection space may preferably be laterally limited by the guide wall for most or the entire length of the conductor connection space.
[0017] The guide wall may be connected to the clamping section of the busbar (the conductor to be connected can be clamped on this clamping section by means of the clamping leg) and extend away from this clamping section at a right angle. The guide wall may extend from the clamping section in the direction of the holding leg of the clamping spring. The guide wall is preferably constructed to be at least long enough so that the clamping edge of the clamping leg of the clamping spring is covered laterally by the guide wall even in the open position of the clamping leg.
[0018] To further improve the stability of the wiring device, a wall protruding towards the clamping spring may be formed on the support section of the busbar, and at least a partial section of the holding leg can be surrounded by this protruding wall. The protruding wall may be constructed such that the holding leg is surrounded by the wall in a U-shape. The holding leg may be supported on the protruding wall of the busbar.
[0019] In addition, the triggering element may be located on this wall of the busbar. The triggering element can thus be supported on this wall of the busbar. This wall can form a bracket for the triggering element in such a way that the triggering element can roll on this wall when the triggering element makes a pivoting movement.
[0020] Furthermore, the object according to the invention can be solved by means of a terminal block, in particular a junction box, which may have at least a wiring device designed and improved as described above.
[0021] 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.
[0022] Particularly 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. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Figure 6 when the clamping legs are transferred to the open position, and DETAILED DESCRIPTION OF THE EMBODIMENTS
[0031] In Figure 1 and Figure 2 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, such as a plastic material. The housing 110 has a conductor inlet opening 111 through which the conductor to be connected can be inserted into the housing 110 along the insertion direction E so as to be connectable to the wiring device 100.
[0032] A busbar 112 and a clamping spring 113 are positioned in the housing 110, wherein, by means of the clamping spring 113, the conductor inserted into the housing 110 can be clamped onto the busbar 112 and thus be wired. As particularly shown in Figure 6As can be seen, the busbar 112 has a clamping section 114 on which the conductor to be connected can be clamped by means of a clamping spring 113 and thus wired. The busbar 112 also has a support section 115 which extends at an angle of 90° relative to the clamping section 114, as is also particularly the case in Figure 6 as can be seen.
[0033] 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 in order 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 clamps the conductor to be connected on the clamping section 114 of the busbar 112 in the clamping position of the clamping leg 117.
[0034] Viewed in 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 delimited downward by 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.
[0035] The triggering element 119 has a pressure surface 120 pointing in the direction of the conductor insertion opening 111, against which the conductor strikes when inserted into the conductor connection space. If the conductor strikes the pressure surface 120, a pivoting movement or tipping movement V of the triggering element 119 along the insertion direction E is triggered, as shown in Figure 1 as depicted.
[0036] Figure 3 The triggering element 119 and the clamping spring 113 are shown in an exploded view.
[0037] The pressure surface 120 of the triggering element 119 is configured on the triggering leg 121 of the triggering element 119. The triggering leg 121 has an elongated shape. The triggering leg 121 forms the main extension plane of the triggering element 119.
[0038] In the open position, the triggering element 119 engages with the clamping leg 117 of the clamping spring 113 to hold the clamping leg 117 in the open position. This is achieved by means of a latching between the triggering element 119 and the clamping leg 117. In the design shown here, the triggering element 119 has a locking arm 122 for this purpose. On the clamping leg 117 of the clamping spring 113, there is a cutout 123 for the locking arm 122, into which the locking arm 122 sinks and can be latched or hooked in from behind onto the edge surface 124 delimiting the cutout 123, as can be seen, for example, in Figure 4 and Figure 5 as can be seen.
[0039] The locking arm 122 is configured in a tabular shape. The locking arm 122 is blanked from the material of the trigger element 119, in particular from the trigger leg 121, and the locking arm is bent in the direction of the clamping leg 117. The locking arm 122 is bent such that it forms a hook that can be hooked behind the edge surface 124 of the cutout 123. In the illustrated embodiment, the locking arm 122 has a substantially C-shaped bend. The C-shaped bend points in the direction of the holding leg 116 of the clamping spring 113. The locking arm 122 is configured on the trigger leg 121 at the mid-width of the trigger leg 121.
[0040] By means of the blanked locking arm 122, an opening 132 in the form of a cutout is configured in the trigger element 119, in particular on the trigger leg 121 of the trigger element 119. By means of this opening 132, which is configured as a window here, the material of the trigger element 119 or the trigger leg 121 is weakened, whereby the material of the trigger element 119 or the trigger leg 121 can be bent more easily. Thereby, the force required for the conductor to be connected to trigger the trigger element and applied to the trigger element 119 or the pressure surface 120 of the trigger element 119 can be reduced.
[0041] The cutout 123 on the clamping leg 117 has the shape of a window, so that the cutout 123 is closed on all its sides. The cutout 123 is configured on the clamping leg 117 at the mid-width of the clamping leg 117.
[0042] In particular, as can be seen in Figure 3 the trigger element 119 is configured as a component independent of the clamping spring 113, wherein the trigger element 119 is detachably fixed to the clamping spring 113. The trigger element 119 is pivotally supported on the clamping spring 113 in such a way that the trigger element 119 is pivotally supported on the holding leg 116 of the clamping spring 113. The trigger element 119 can pivot relative to the position-fixed holding leg 116.
[0043] To configure the pivotable support, the holding leg 116 of the clamping spring 113 has a cutout 125 into which the trigger element 119 or the trigger leg 121 engages and is thereby supported there. The trigger leg 121 engages with its free end section 126 opposite the pressure surface 120 into the cutout 125. The free end section 126 is configured in a tongue shape. As can be seen in Figures 3 to 5 the free end section 126 (by means of which the trigger leg 121 or the trigger element 119 engages into the cutout 125) has a narrower width than the rest of the trigger element 119 or the trigger leg 121. The trigger element 119 or the trigger leg 121 of the trigger element 119 hooks into the cutout 125 of the holding leg 116 with its free end section 126.
[0044] Additionally, the retaining leg 116 of the clamping spring 113 also sinks into an opening 127 constructed in the trigger element 119 or the trigger leg 121 of the trigger element 119. The retaining leg 116 inserts its free end 128 into the opening 127. The retaining leg 116 has a width narrowing at the free end 128, so that the retaining leg 116 has a stop edge 129, and the retaining leg 116 is hooked on the trigger element 119 with this stop edge 129. The retaining leg 116 can be prevented from being inserted too deep into the opening 127 by the stop edge 129. Together with the trigger element 119 sinking into the cutout 125 constructed in the retaining leg 116, the above method enables anti-tipping support of the trigger element 119 on the retaining leg 116. The opening 127 has a window shape.
[0045] In the design shown here, the trigger element 119 is constructed to be bent twice along its length. Therefore, the trigger element 119 has a wavy shape along its length. In the region of the first bending portion 130, the locking arm 122 is blanked out from the trigger element 119 and is bent out of the main extension plane of the trigger element 119 accordingly. The opening 132 extends in the region of the first bending portion 130. The opening 127 is constructed in the region of the second bending portion 131 of the trigger element 119. The opening 127 also causes material weakening of the trigger element 119 in the region of the second bending portion 131, whereby the spring characteristics of the trigger element 119 can be further improved, and thus the triggerability of the trigger element 119 by means of the conductor L to be connected can be further improved.
[0046] A rotational bearing portion 133 is constructed in the region of the opening 127. When the trigger element is triggered by the conductor to be connected, the trigger leg 121 can pivot around the rotational bearing portion 133. In the design shown here, the rotational bearing portion 133 consists of two pins 134A, 134B that project into the opening 137. The two pins 134A, 134B are arranged to point towards each other. Therefore, the axis of rotation of the trigger element 119 lies in the pins 134A, 134B. The two pins 134A, 134B abut against the retaining leg 116 of the clamping spring 113, so that when the trigger element 119 is operated or triggered, the two pins 134A, 134B can roll on the retaining leg 116, whereby the trigger element 119 or the trigger leg 121 of the trigger element 119 can pivot or tip over.
[0047] Figure 1Shows 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, and thereby releases the conductor connection space formed between the clamping section 114 of the busbar 112 and the clamping leg 117 of the clamping spring 113, so that the conductor to be connected can be inserted into this conductor connection space through the conductor insertion opening 111.
[0048] When the conductor to be connected is inserted into the conductor connection space along the insertion direction E, the conductor to be connected strikes against the pressure surface 120 of the trigger element 119. Thereby, the trigger element 119 performs a tipping movement or a pivoting movement V along the insertion direction E, whereby the locking arm 122 of the trigger element 119 disengages from the cutout 123 of the clamping leg 116. Thereby, the clamping leg 117 disengages from the trigger element 119, so that the clamping leg 117 can automatically swing away from the trigger element 119 or the holding leg 116 by its restoring force or its spring force, and pivot 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. Figure 2 Shows the clamping position without a connected conductor.
[0049] If the conductor is to be loosened again from the clamping position, the operating element 139 is moved along the operating direction B inside the operating recess 140 of the housing 110, as shown in Figure 2 depicted. By the displacement movement of the operating element 139 along the operating direction B, the operating element 139 presses against the clamping leg 117 with its operating section 141, causing the clamping leg to move away from the conductor, and thus causing the clamping leg 117 to pivot in the direction of the holding leg 116, as visible in Figure 4 and Figure 5 depicted. The operating element 139 exerts a pushing force along the operating direction B on the clamping leg 117, causing the clamping leg 117 to move in the direction of the holding leg 116 so far that the clamping leg 117 again engages with the trigger element 119 by sinking the locking arm 122 into the cutout 123, and thereby bringing the clamping leg into the open position and holding it there.
[0050] In order for the locking arm 122 to be able to sink unhindered into the cutout 123, and in order for the operating element 139 pressing against the clamping leg 117 not to impede the above-mentioned movement, the operating element 139 has a cutout 142 in the region of its operating section 141, into which the locking arm 122 can sink, as visible in Figure 5 depicted. The cutout 142 is configured in the form of a recess on the operating section 141.
[0051] The operating element 139 is linearly movably supported in the operating recess 140 of the housing 110.
[0052] As can be seen in Figure 1 , 2 and Figure 6 as shown, a guide wall 143 is constructed on the busbar 112. By means of this guide wall 143, the conductor to be connected can be reliably guided to the trigger element 119 or to the pressure surface 120 of the trigger element 119. In the design shown here, the guide wall 143 is constructed to be so long that it extends from the wall 144 of the housing 110 that defines the conductor inlet opening 111 of the housing 110 to the pressure surface 120 of the trigger element 119. The conductor connection space is laterally delimited by this guide wall 143, so that it is possible to prevent the conductor to be connected from laterally missing the pressure surface 120 of the trigger element 119 during the wiring process and thus from passing by the trigger element 119 laterally.
[0053] The guide wall 143 is connected to the clamping section 114 of the busbar 112 (the conductor to be connected can be clamped on this clamping section by means of the clamping leg 117), and extends away from the clamping section 114 at a right angle. The guide wall 143 extends away from the clamping section 114 in the direction of the retaining leg 116 of the clamping spring 113. The guide wall 143 is constructed to be so wide in the direction of the retaining leg 116 that the clamping edge 118 of the clamping leg 117 of the clamping spring 113 is laterally covered by the guide wall 143 even in the open position of the clamping leg 117, as can be seen in Figure 6 as shown.
[0054] To further improve the stability of the wiring device 100, a wall 145 protruding in the direction of the clamping spring 113 is constructed on the support section 115 of the busbar 112, and this protruding wall at least surrounds the free end 128 of the retaining leg 116. In the design shown here, the protruding wall 145 has a U-shaped shape, so that the free end 128 of the retaining leg 116 is surrounded by the wall 145 in a U-shape. The retaining leg 116 can be supported on the protruding wall 145 of the busbar 112.
[0055] The trigger element 119 is located on the wall 145 of the busbar 112. The trigger element 119 can thus also be supported on the wall 145 of the busbar 112. The wall 145 can form a support for the trigger element 119 in such a way that the trigger element 119 can roll on the wall 145 during the pivoting movement V. For this purpose, the trigger element 119 abuts on the wall 145 in the region of its second bending section 131, as can be seen in particular in Figure 6 as shown. The trigger element 119 can slide along the wall 145 during its pivoting movement V.
