Abstract
Description
Technical Field
[0001] The invention relates to a connection device for connecting electrical conductors. Background Art
[0002] Such terminal devices usually have a clamping spring designed as a helical torsion spring (Schenkelfeder), which has a retaining leg and a clamping leg, wherein the conductor introduced into the terminal device can be clamped to the 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 already be transferred to the release position by means of an operating element before the conductor is introduced and thus operated in order to pivot the clamping spring or the clamping leg away from the busbar, thereby allowing the conductor to be introduced into the intermediate space between the busbar and the clamping spring. Only in the case of rigid and therefore stable conductors 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 flexible conductors, the user must first pivot the clamping spring away from the busbar by operating the operating element, thereby allowing the flexible conductor to be introduced. In order to clamp the introduced conductor, the operating element must be manually operated by the user again to transfer the clamping spring from the release position to the clamping position. For the user, the manual operation of the operating element makes the assembly or connection of the conductor difficult because the manual operation is cumbersome and therefore also increases the time consumption. Summary of the invention
[0003] The object of the present invention is to provide a connection device in which, in particular, the connection of flexible conductors can be simplified.
[0004] According to the invention, this object is achieved by means of the features of the independent claim. Embodiments and advantageous developments of the invention which achieve the object are given in the dependent claims.
[0005] The terminal device according to the invention comprises: a housing with a conductor insertion opening; a busbar arranged in the housing, the busbar having a busbar pull-out portion (Strombalkendurchzug), in which a conductor connection space is formed; a clamping spring arranged in the housing, the clamping spring having a retaining leg and a clamping leg, wherein the clamping leg can be transferred into a clamping position and an open position, wherein the clamping leg engages with the retaining leg in order to retain the clamping leg in the open position; an operating element, by means of which the clamping leg can be transferred from the clamping position to the open position. In addition, the terminal device has a release element, which can be pivoted in such a way that when the conductor to be connected is introduced into the conductor connection space in the insertion direction, the release element can be actuated in such a way that the clamping leg is disengaged from the retaining leg and is pivoted from the open position to the clamping position.
[0006] At this time, with the aid of the wiring device according to the invention, it is also possible to simply and reliably connect a flexible conductor and clamp it to the busbar. The clamping spring is preferably constructed as a helical torsion spring having a retaining leg and a clamping leg that is pivotally constructed relative to the retaining leg. By 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 which the clamping leg is arranged spaced apart from the wall of the busbar or the busbar pull-out portion, and the conductor to be connected can be introduced into the intermediate space or conductor connection space thus constructed between the wall of the busbar or the busbar pull-out portion and the clamping leg, or can be led out from it, and in the clamping position, the clamping leg can be placed against the wall of the busbar or the busbar pull-out portion or on the connected conductor in order to clamp the conductor to the wall of the busbar or the busbar pull-out portion. The transfer of the clamping leg, in particular the transfer from the clamping position to the open position, is achieved by means of an operating element. The operating element is preferably guided in a purely linear manner in the housing so that it can move. As soon as the clamping leg reaches the open position, the clamping leg engages with the retaining leg so that the clamping leg can be held in the open position by the retaining leg and thus can prevent the clamping leg from being undesirably turned back from the open position into the clamped position. Thus, the clamping spring can engage with itself in order to hold the clamping leg in the open position. Thus, no further elements, such as, for example, the operating element itself, are required to hold the clamping leg in the open position.
[0007] If the clamping leg reaches the open position, the operating element can therefore move away from the clamping leg of the clamping spring in the opposite direction of the operating direction of the operating element, without the clamping leg following the operating element. Therefore, 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 means of the retaining leg, the operating element can move back to its initial position in the opposite direction of the operating direction, so that in the open position of the clamping leg, there is no longer an active connection between the operating element and the clamping leg. By the swinging movement of the release element, the clamping leg can be disengaged from the retaining leg again in order to pivot back into the clamping position and clamp the conductor to be connected to the busbar inside the busbar pull-out portion of the busbar. The swinging movement of the release element can be triggered by the conductor to be connected itself, in that when the conductor to be connected is introduced into the conductor connection space, the conductor hits the release element and thereby triggers a tilting movement or a pivoting movement of the release element. The conductor is clamped by means of the clamping legs of the clamping spring in a busbar pull-out which is constructed by means of an opening in the busbar and has a wall extending from the main extension plane of the busbar in the direction of introduction of the conductor, against which the conductor to be connected is clamped in the clamping position by means of the clamping legs.
[0008] The release element is preferably connected to the clamping spring. Particularly preferably, the release element can be constructed in one piece with the retaining leg of the clamping spring. Then, the release element can be constructed in the form of a leg, which can be molded on the free end of the retaining leg. The retaining leg can then be positioned between the clamping leg and the release element. The release element preferably extends at an angle or bent relative to the retaining leg. The connection area between the retaining leg and the release element can have a 90° bend. If the release element is constructed in one piece with the retaining leg, the release element can be constructed by the spring plate of the clamping spring. By connecting the release element to the clamping spring, no additional bearing position of the release element is required in the wiring device, thereby saving the necessary structural space.
[0009] The clamping spring can be positioned inside the connection device in such a way that the clamping spring can extend with its retaining leg and its clamping leg into the busbar pull-out. By extending the clamping leg and the retaining leg into the busbar pull-out, an improved support of the clamping spring inside the connection device is achieved, since the clamping spring can be held in position by the busbar pull-out, and thus a tilting of the clamping spring inside the connection device can be prevented.
[0010] Seen in the direction of introduction, the release element can be positioned below the busbar pull-out portion. This can ensure that the conductor is introduced far enough into the housing and then into the conductor connection space, thereby ensuring that the conductor is reliably clamped in the area of the busbar pull-out portion. In the non-operating position, the release element preferably extends transversely to the direction of introduction of the conductor, so that the release element can construct the boundary of the conductor connection space in the direction of introduction. The retaining leg of the clamping spring can then be constructed so long that, viewed in the direction of introduction, the retaining leg can extend from the busbar pull-out portion again below the busbar pull-out portion, so that the release element can be connected to the retaining leg outside the busbar pull-out portion. The connection area of the release element on the retaining leg can then be positioned outside the busbar pull-out portion.
[0011] For clamping and thus for contacting the conductor to be connected, the wall of the busbar pull-out can form a contact region, to which the conductor to be connected can be clamped in the clamping position of the clamping legs of the clamping spring. The contact region can be formed, for example, by a clamping edge formed on the wall, to which the conductor to be connected can be clamped in the clamping position by means of the clamping legs. The clamping edge can be formed on the edge of the busbar pull-out or by a bend or offset or arch formed along the wall of the busbar pull-out. By clamping on the clamping edge, a point contact of the conductor can be formed on the busbar in the region of the busbar pull-out.
[0012] The clamping leg can be engaged with the retaining leg in its open position in such a way that the clamping leg can be locked on the retaining leg in its open position. Thus, in the open position, the clamping spring can be locked by itself so as to be automatically held in the open position. Thus, no further elements are required in addition to the clamping spring itself for holding the clamping leg in the open position.
[0013] To implement the locking, the retaining leg can have at least one locking tab and the clamping leg can have at least one locking opening, wherein in the open position the at least one locking tab can engage with the at least one locking opening. The at least one locking tab can pass through the at least one locking opening in the open position and the barb is hooked at the at least one locking opening at an edge defining the at least one locking opening. The at least one locking tab can be cut out of the material of the retaining leg and bent in the direction of the clamping leg.
[0014] The operating element can have a cutout that matches at least one locking tab of the holding leg. When the clamping leg is transferred from the clamping position to the open position, it is thus possible to prevent the operating element from obstructing the locking between the clamping leg and the holding leg, because the locking tab can sink into the cutout of the operating element. The cutout is preferably formed on an operating section of the operating element, which abuts against the clamping leg of the clamping spring when the clamping leg is transferred from the clamping position to the open position.
[0015] The retaining leg is preferably not configured to be straight, but the retaining leg may have a bend. Along the length of the retaining leg, the retaining leg preferably has a bend through the bend. The bending axis of the bend preferably extends transversely to the length of the retaining leg. The bend is particularly preferably configured to be 90°.
[0016] ° Bend. By means of such a bend on the holding leg, it can be ensured that the locking between the holding leg and the clamping leg is reliably released when the release element is actuated.
[0017] The clamping spring can be supported on the busbar by placing the clamping spring on the busbar. The clamping spring can be placed on the busbar with its retaining legs. The clamping spring can be supported on the busbar with a force fit and / or a form fit.
[0018] In order to be able to form a particularly reliable support of the clamping spring on the busbar, the clamping spring can have at least one retaining tab, which can engage in at least one retaining opening configured on the busbar. The at least one retaining tab can be configured on the retaining leg, preferably in the area of the retaining leg, in which the retaining leg is placed on the busbar. The clamping spring can be inserted into the busbar by means of the at least one retaining tab. The at least one retaining opening is preferably configured to be spaced apart from the busbar pull-out portion. It is particularly preferred that the clamping spring has two retaining tabs arranged spaced apart from each other, and the busbar has two retaining openings arranged spaced apart from each other. This enables a particularly anti-tilting support of the clamping spring on the busbar.
[0019] In addition to supporting the clamping spring on the manifold, the clamping spring can also be supported on the housing. The housing can have a bearing pin on which the clamping spring can be supported with an arcuate section formed between the clamping leg and the retaining leg. The clamping spring can be positioned on the bearing pin in such a way that the arcuate section can surround the bearing pin. Furthermore, by supporting the clamping spring on the bearing pin of the housing, it can be ensured that a defined pivot point of the clamping spring is formed when the release element is actuated.
[0020] The terminal device constructed and improved as described above can be part of a terminal block, which can be constructed as a terminal block or a printed circuit board terminal block, for example. The terminal device can also be used in a plug connector. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] exist Figures 1 to 4 1 shows a wiring device 100 according to the present invention. The wiring device 100 has a housing 110. The housing 110 can be made of an insulating material, such as plastic. The housing 110 has a conductor introduction opening 111, through which a conductor L to be connected can be introduced into the housing 110 along an introduction direction E so as to be connected to the wiring device 100.
[0035] A busbar 112 and a clamping spring 113 are positioned in the housing 110, wherein a conductor L introduced into the housing 110 can be clamped on the busbar 112 by means of the clamping spring 111 and thus connected. The busbar 112 has a busbar pull-out portion 114, in which a conductor connection space 115 is formed, so that the conductor L to be connected can be clamped in the busbar pull-out portion 114 by means of the clamping spring 113, so as to connect the conductor L. The busbar pull-out portion 114 is formed by an opening 139 in the busbar 112 and a wall 128 extending from the opening 139 in the introduction direction E, as shown in FIG. Fig.10 As can be seen in .
[0036] The clamping spring 113 is designed as a helical torsion spring. The clamping spring 113 has a retaining leg 116 and a clamping leg 117. The clamping leg 117 can be pivoted relative to the retaining leg 116 in order to transfer the clamping leg 117 to a clamping position and an open position. The clamping leg 117 has a clamping edge 118 on its free end section, which clamps the conductor L to be connected to the busbar pull-out part 114 of the busbar 112, in particular to the wall 128 of the busbar pull-out part 114, in the clamping position of the clamping leg 115. The clamping spring 113 extends into the busbar pull-out part 114 not only with its clamping leg 117 but also with its retaining leg 116.
[0037] The conductor L is clamped in the conductor connection space 115. The conductor L to be connected can be introduced into the conductor connection space 117 through the conductor introduction opening 111. The conductor connection space 115 is constructed inside the busbar pull-out part 114 of the busbar 112. In the design shown here, the conductor connection space 115 is surrounded by the wall 128 of the busbar pull-out part 114. The wall 128 of the busbar pull-out part 114 at least partially constitutes the lateral boundary of the conductor connection space 115. The wall 128 of the busbar pull-out part 114 constitutes a contact area 129, to which the conductor L to be connected is clamped in the clamping position of the clamping leg 117 of the clamping spring 113. The contact area 129 is constructed by a clamping edge constructed on the wall 128, to which the conductor L to be connected can be clamped in the clamping position by means of the clamping leg 117.
[0038] The conductor connection space 115 is delimited downwardly by the release element 119 when viewed in the introduction direction E. The release element 119 is positioned below the busbar pull-out portion 114 when viewed in the introduction direction E. The release element 119 is constructed integrally with the clamping spring 113. Therefore, the release element 119 is constructed of a spring plate like the clamping spring 113. The release element 119 is integrally connected to the retaining leg 116 of the clamping spring. The connection area 121 of the release element 119 on the retaining leg 116 has a 90° bend, so that the release element 119 extends out of the retaining leg 116 in a bent manner. Here, the release element 119 is constructed in the form of a rectangular leg, which extends transversely to the introduction direction E of the conductor L in the open position of the clamping leg 117.
[0039] The release element 119 is positioned on the retaining leg 116 in a pivotable or tiltable manner so that it can be tilted or pivoted relative to the retaining leg 116. The pivot axis of the release element 119 is located in the connection region 121 of the release element 119 on the retaining leg 116. The release element 119 has a pressure surface 120 pointing in the direction of the conductor introduction opening 111, against which the conductor L can strike when it is introduced into the conductor connection space 115. If the conductor L strikes the pressure surface 120, a pivoting movement or tilting movement V of the release element 118 in the introduction direction E is caused, as in Figure 3 and 4 As drawn in .
[0040] In the open position of the clamping leg 117 of the clamping spring 113, the clamping leg 117 engages with the retaining leg 116, as for example in Figure 2 Here, the clamping leg 117 is locked with the holding leg 116.
[0041] Especially in Figure 9a and Figure 9b As can be seen in FIG. 1 , the retaining leg 116 has a locking tab 122 and the clamping leg 117 has a locking opening 123. In the open position of the clamping leg 117, the locking tab 122 engages with the locking opening 123, so that the locking tab 122 passes through the locking opening 123 in the open position and can be hooked on the locking opening 123 at the edge defining the locking opening 123, as in FIG. Figure 9a and Figure 9b Here, the locking tab 122 is cut from the material of the retaining leg 116 and is configured to be bent in the direction of the clamping leg 117 .
[0042] If the conductor L to be connected now strikes the pressure surface 120 and thereby a pivoting movement V of the release element 119 in the insertion direction E is achieved, as in Figure 3 and Figure 4As shown in FIG. 1 , the clamping leg 117 is disengaged from the holding leg 116 by the deflection movement of the holding leg 116 connected to the release element 119, whereby the clamping leg 117 can be swung in the direction of the conductor L so as to clamp the conductor L introduced into the conductor connection space 115 onto the busbar pull-out portion 114 of the busbar 112, as shown in FIG. Figure 3 and Figure 4 As shown in .
[0043] In order to facilitate the release of the lock between the retaining leg 116 and the clamping leg 117, the retaining leg 116 is not designed to be straight along its length, but the retaining leg has a bend 124. Therefore, the retaining leg is designed to be bent along the length of the retaining leg 116. The bending axis of the bend 124 extends transversely to the length of the retaining leg 116. The bend 124 is shown here as a 90° bend.
[0044] The holding leg 116 has a first leg section 125 and a second leg section 126. The two leg sections 125, 126 are connected to each other by a bend 124. The first leg section 125 is connected to the clamping leg 117 by an arc section 127. The second leg section 126 is connected to the release element 119 by a connection area 121. When the release element 119 is operated, the second leg section 126 can follow the pivoting movement V of the release element 119 in order to release the locking between the holding leg 116 and the clamping leg 117. The holding leg 116 extends into the busbar pull-out 114 with the second leg section 125. The first leg section 125 is positioned outside the busbar pull-out 114. The holding leg 116 and thus the clamping spring 113 are placed on the busbar 112 with the first leg section 125. Unlike the second leg section 126, the first leg section 125 is arranged in a fixed position relative to the collecting plate 112, so that the first leg section 125 is supported in a positionally stable manner on the collecting plate 112. The first leg section 125 and the second leg section 126 extend at an angle of 90° to each other.
[0045] In the embodiment shown here, the clamping spring 113 is supported at two points.
[0046] On the one hand, the clamping spring 113 is supported on the manifold 112. This is achieved by connecting the clamping spring 113 to the manifold 112 in a form-fitting manner. The form-fitting connection is formed by two retaining tabs 130a, 130b formed on the clamping spring 113, which respectively engage in retaining openings 131a, 131b formed on the manifold 112, such as, for example, in Figure 5 and Figure 6 As can be seen in .
[0047] Two retaining tabs 130a, 130b are arranged on the retaining leg 116 of the clamping spring 113 at a distance from each other. The two retaining tabs 130a, 130b are respectively constructed of materials that are freely stamped and bent from the retaining leg 116. The two retaining tabs 130a, 130b extend on the opposite longitudinal sides of the retaining leg 116. The two retaining tabs 130a, 130b are constructed in the region of the first leg section 125 of the retaining leg 116. The clamping spring 113 can be inserted into the busbar 112 by means of the two retaining tabs 130a, 130b. The two retaining openings 131a, 131b on the busbar 112 are constructed at a distance from the busbar pull-out portion 114 on the busbar 112. The two retaining openings 131a, 131b are constructed on the opposite longitudinal sides of the busbar 112. In the embodiment shown here, the two holding openings 131a, 131b are each formed in the form of a U-shaped free punching on the longitudinal side of the collecting plate 112, such as in particular Fig.10 As can be seen in .
[0048] Furthermore, the clamping spring 113 is supported by its arc-shaped section 127 on a bearing bolt 132 of the housing 110, as in Figures 1 to 4 As can be seen in .
[0049] When the conductor L to be connected is introduced into the conductor connection space 115 in the insertion direction E, the conductor L to be connected strikes the pressure surface 120 of the release element 119. As a result, a tilting movement or a pivoting movement V of the release element 119 in the insertion direction E is achieved, whereby the second leg section 122 of the holding leg 116, which is connected to the release element 119 via the connection area 121, also follows the pivoting movement V in the insertion direction E and is thereby disengaged from the clamping leg 117 in that the locking tab 122 of the holding leg 116 is unhooked from the locking opening 123 of the clamping leg 116. As a result, the clamping leg 117 is disengaged from the holding leg 116, so that the clamping leg 117 can be automatically pivoted away from the holding leg 116 in the direction of the conductor L introduced into the conductor connection space 115 by its restoring force or its spring force, so that the conductor L can be clamped to the contact area 129 of the wall 128 of the busbar 112, as for example in Figure 7 and Figure 8 As shown in .
[0050] If the conductor L is to be released again from the clamped position, the actuating element 133 is displaced in the actuating direction B, e.g. Figure 1 and Figure 2As can be seen in . By the displacement movement of the operating element 133, the operating element 133 with its operating section 134 pushes the clamping leg 117 away from the conductor L, so that the clamping leg 117 is pivoted in the direction of the retaining leg 116. The operating element 133 exerts pressure on the clamping leg 117 in the operating direction B until the clamping leg 117 is reengaged with the retaining leg 116 and is thus in the open position and is held there. In order that the retaining leg 116 and its locking tab 122 can sink into the locking opening 123 of the clamping leg 117 without hindrance and can hook there, a recess 135 is formed on the operating section 134, as shown in Fig.11 As can be seen in FIG. 1 , the recess matches the locking tab 122 of the holding leg 116. The locking tab 122 of the holding leg 116 can be sunk into the recess 135. The operating element 133 is supported in the housing 110 so that it can be moved linearly. Once the clamping leg 117 is engaged with the holding leg 116 and the clamping leg 117 can thus be held in the open position by the holding leg 116, the operating element 133 can be moved back to its initial position in the opposite direction of the operating direction B, as in the case of Figure 3 and Figure 4 In this initial position, the operating element 133 can be positioned with its upper side 137 having the tool insertion 136 flush with an outer surface 138 of the housing 110 .
