Abstract
Description
Technical Field
[0001] This utility model relates to a connection device for connecting electrical conductors. Background Technology
[0002] Such connection devices typically have a clamping spring configured as a helical torsion spring, which has a retaining leg and a clamping leg. A conductor introduced into the connection device can be clamped onto the busbar by means of the clamping leg of the clamping spring. If a flexible conductor is being clamped, in particular, the clamping spring must be moved to the open position by means of an actuating element before the conductor is introduced, thereby actuating the clamping spring or clamping leg to deflect it away from the clamping section of the busbar, thus allowing the conductor to be introduced into the intermediate cavity between the clamping section of the busbar and the clamping spring. Only with rigid and therefore stable conductors can the conductor apply sufficient force to the clamping spring or its clamping leg to deflect the clamping leg away from the busbar without requiring user actuation of the actuating element. With flexible conductors, the user must first deflect the clamping spring away from the busbar by actuating the actuating element to allow the flexible conductor to be introduced. To clamp the introduced conductor, the user must manually operate the control element again to move the clamping spring from the released position to the clamped position. This manual operation of the control element makes conductor installation or connection difficult for the user, as it is cumbersome and therefore time-consuming. Utility Model Content
[0003] The purpose of this invention is to provide a connection device that simplifies the connection of, in particular, flexible conductors.
[0004] According to this invention, this objective is achieved by the features of the independent claim. Advantageous designs and improvements of this invention are given in the dependent claims.
[0005] The connecting device according to this utility model has a housing with a conductor inlet opening, a busbar arranged in the housing, and a clamping spring arranged in the housing. The busbar has a clamping section and a support section extending at an angle to the clamping section. The clamping spring has a retaining leg and a clamping leg connected to the retaining leg via an arcuate section. The clamping leg can be moved to a clamped position and an open position. The retaining leg has an opening in which the clamping leg is guided. Furthermore, the connecting device has an operating element with an operating section by means of which the clamping leg of the clamping spring can be moved from the clamped position to the open position when the operating element moves along the operating direction. In the open position, the operating element is introduced into the opening of the retaining leg, and to hold the clamping leg in the open position, the operating element is clamped in the opening by the spring force of the clamping leg. In addition, the connecting device has a deflectable supporting trigger element with a pressure surface that can be manipulated by the conductor to be connected in order to move the clamping spring from the open position to the clamping position, such that the trigger element is deflected and pressure is applied to the clamping leg of the clamping spring by the deflection movement of the trigger element, so that the operating element is released from the clamping position and the clamping leg is deflected from the open position to the clamping position.
[0006] With the aid of the connection device according to this invention, flexible conductors can now be easily and reliably connected and clamped relative to the busbar, particularly to the clamping section of the busbar. The clamping spring is preferably constructed as a helical torsion spring, having a retaining leg and a clamping leg configured to deflect relative to the retaining leg. Conversely, the retaining leg is held in a fixed position. By deflecting the clamping leg of the clamping spring, the clamping leg can be moved to an open position and a clamped position. In the open position, the clamping leg is spaced apart from the clamping section of the busbar, and the conductor to be connected can be introduced into, or drawn out from, the intermediate cavity or conductor connection cavity thus formed between the clamping section of the busbar and the clamping leg. In the clamped position, the clamping leg can abut against the clamping section of the busbar or the connected conductor to clamp the conductor relative to the clamping section of the busbar. The transfer of the clamping leg from the clamped position to the open position is achieved by means of an actuating element. The operating element is preferably guided linearly within the housing along the operating direction. As the operating element moves along the operating direction, it extends into the opening of the retaining leg. Once the clamping leg reaches the open position due to the movement of the operating element, the clamping leg of the clamping spring clamps the operating element against the edge of the opening of the retaining leg and thus against the retaining leg, achieving clamping of the operating element within the opening. Thus, the clamping leg can be automatically held in the open position by means of the operating element, and the operating element is clamped in a fixed position between the clamping leg and the retaining leg within the clamping spring. The clamping leg can be held in the open position by the operating element clamped to the clamping spring, thereby preventing the clamping leg from undesirably deflecting back to the clamped position from the open position. Therefore, the clamping spring can form a closed force system with the operating element in the open position. The clamping leg can be manipulated by the deflection movement of the trigger element, such that the clamping leg is released from the open position and can deflect back to the clamped position to clamp the conductor to be connected onto the clamping section of the busbar. The deflection movement of the trigger element can be triggered by the conductor to be connected itself, because when the conductor to be connected is introduced into the conductor connection cavity, the conductor comes into contact with the pressure surface of the trigger element, thereby triggering the tilting or deflection movement of the trigger element. During the deflection movement of the trigger element, the trigger element works in conjunction with the clamping leg of the clamping spring in such a way that the trigger element contacts the clamping leg during deflection and applies pressure to the clamping leg, causing the actuating element to release from the clamping position in the opposite direction of the actuation direction through the pressure and the spring force of the clamping leg. This allows the actuating element to return to its original position in the opposite direction of the actuation direction, thereby releasing the clamping leg and allowing the clamping leg to deflect from the open position to the clamping position.
[0007] The retaining leg is preferably constructed such that it crosses the clamping leg, such that the clamping leg extends into an opening constructed in the clamping leg and can move from the clamping position to the open position and back within the opening.
[0008] The retaining leg of the clamping spring can be constructed such that it has at least one retaining surface extending perpendicularly to the main extending plane of the retaining leg, onto which the operating element is clamped in the open position of the clamping spring. The retaining surface preferably forms a contact surface for the operating element in the open position of the clamping spring. The retaining surface can preferably extend along the operating direction of the operating element, allowing the operating element to rest planarly against the retaining surface with its operating section in the open position of the clamping leg. The retaining surface enables the operating element to be clamped within the clamping spring as stably and tilt-resistant as possible. The clamping leg allows the operating element to be pressed against the retaining surface in the open position of the clamping leg. The retaining leg is preferably positioned such that its main extending plane extends transversely to the operating direction of the operating element.
[0009] For example, the retaining leg can be shaped such that it has two L-shaped curved retaining tabs defining openings, wherein a first retaining surface can be formed on the first retaining tab, and a second retaining surface can be formed on the second retaining tab. The two retaining tabs are positioned spaced apart from each other and preferably extend parallel to each other, so that the opening extends between the two retaining tabs. In this design, the opening can be U-shaped, such that the opening is constructed to open to one side. The retaining surfaces formed on the two retaining tabs extend symmetrically to each other, so that the operating element can be evenly abutted against the two retaining surfaces in the open position of the clamping leg.
[0010] To prevent excessive insertion of the operating element into the opening, the operating element may have a first stop surface on its operating section, through which it is supported on a first retaining tab in the open position. The operating element may also have a second stop surface on its operating section, through which it is supported on a second retaining tab in the open position. These two stop surfaces are preferably symmetrically arranged on two opposing sides of the operating section of the operating element. These stop surfaces may be constructed as edges protruding from each side of the operating section.
[0011] To ensure reliable and stable support of the clamping spring within the housing, the clamping spring may have a mating leg in addition to the retaining leg and clamping leg. This mating leg supports the clamping spring on the support section of the busbar. The mating leg may be formed at the same end as the retaining leg on the curved section of the clamping spring. The mating leg may extend at a right angle to the retaining leg. When the clamping leg moves from the clamped position to the open position, it can move towards the mating leg. The mating leg may be shaped such that it is cut from the material of the retaining leg, thereby creating an opening in the retaining leg through this cutting. By supporting the mating leg on the support section of the busbar, the metal of the clamping spring can be supported relative to the metal of the busbar, thus avoiding support of the clamping spring relative to the wall of the housing, which is preferably made of insulating material. This prevents force from being introduced into the housing, especially when the clamping leg is in the open position.
[0012] Alternatively, instead of having a mating leg for support, the clamping spring is supported on the clamping section of the busbar by its retaining leg, wherein the clamping section of the busbar can extend through an opening in the retaining leg. The retaining leg here can surround the clamping section of the busbar. Therefore, the clamping spring can be attached to the clamping section of the busbar via its retaining leg.
[0013] To ensure reliable clamping of the operating element onto the retaining leg in the open position of the clamping leg in this design, the retaining leg may have two retaining tongues in its opening region, onto which the operating element can be clamped in the open position of the clamping leg. The retaining tongues may be constructed on two opposing edge regions of the opening. The two retaining tongues may be cut from the edge region of the material surrounding the opening of the retaining leg and bent into the desired shape. Preferably, the retaining tongues are each constructed as arcuate surfaces, thus forming an introduction ramp for guiding the operating element along the two retaining tongues into the opening.
[0014] In order to reliably clamp the operating element onto the retaining leg when the clamping leg is in the open position, the operating element can have a contact surface that extends at an angle to the operating direction of the operating element, and the operating element can be supported on the arcuate section of the clamping spring by means of the contact surface when the clamping leg of the clamping spring is in the open position.
[0015] The trigger element can be rotatably supported on the wall of the housing. The trigger element can have a shaft element, through which the trigger element can be supported on the housing and the shaft element can form a rotation axis about which the trigger element can deflect.
[0016] The trigger element can be configured to have a contact section with a pressure surface and an eccentrically formed second actuating section. The eccentrically formed second actuating section rolls its outer circumferential surface on the bottom surface of the clamping leg during the deflection movement of the trigger element, thereby applying pressure to the clamping leg. During the deflection movement of the trigger element, the trigger element can contact the clamping leg with its eccentrically formed second actuating section and, through rolling motion, press the clamping leg upwards in the direction of the actuating element. This releases the clamping element from the clamping spring, allowing the actuating element to release the clamping leg, which can then deflect from the open position to the clamped position.
[0017] The connection device constructed and improved as described above can be part of a connection terminal, which can be configured as, for example, a wiring terminal or a circuit board connection terminal. The connection device can also be used in a plug connector. Attached Figure Description

[0030] Figures 1 to 6 The diagram shows a connecting device 100 according to a first embodiment of the present invention. The connecting device 100 has a housing 110. The housing 110 may be formed of an insulating material, such as a plastic material. The housing 110 has a conductor introduction opening 111 through which a conductor L to be connected can be introduced into the housing 110 in the introduction direction E so that it can be connected to the connecting device 100.
[0031] Busbar 112 and clamping spring 113 are positioned within housing 110, wherein, by means of clamping spring 113, a conductor L introduced into housing 110 can be clamped relative to busbar 110 and thereby connected. Busbar 110 has a clamping section 114 and a support section 115 extending at an angle, particularly a right angle, relative to the clamping section 114. The clamping spring 113 achieves clamping of the conductor L to be connected relative to the clamping section 114 of the busbar, as in... Figure 6 As can be seen in the image.
[0032] The clamping spring 113 is constructed as a helical torsion spring. The clamping spring 113 has a retaining leg 116 and a clamping leg 117. The clamping leg 117 is deflectable relative to the retaining leg 116 to move the clamping leg 117 to a clamped 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 relative to the clamping section 114 of the busbar 112 in the clamped position of the clamping leg 117.
[0033] Clamp your legs together 117 from as if in Figure 5 and 6 The clamping position shown is as in Figures 1 to 4The shift to the open position shown is achieved by means of an actuating element 120 guided linearly within the housing 110. The actuating element 120 moves along an actuating direction B, which extends parallel to the introduction direction E of the conductor L to be connected. The clamping leg 117 is held in its open position by means of the actuating element 120 by pressing the actuating section 121 of the actuating element 120 against the upper side 122 of the clamping leg 117, and simultaneously clamped between the clamping leg 117 and the retaining leg 116 of the clamping spring 113 by the spring force of the clamping leg 117.
[0034] The retaining leg 116 is connected to the clamping leg 117 via an arcuate section 119. The retaining leg 116 extends from the arcuate section 119 such that the main extension plane H of the retaining leg 116 is oriented laterally or perpendicularly to the actuation direction B of the actuating element 120. The retaining leg 116 and the clamping leg 117 intersect.
[0035] The retaining leg 116 has an opening 123 into which a clamping leg 117 extends and is deflectable to move to a clamped position and an open position. In the open position of the clamping leg 117, the actuating element 120, with its actuating section 121, also extends into the opening 123 of the retaining leg 116, wherein, in order to hold the clamping leg 117 in the open position, the actuating element 120 is clamped in the opening 123 by a spring force acting on the clamping leg 117 opposite to the actuating direction B.
[0036] exist Figures 1 to 6 In the design shown, the retaining leg 116 has two parallel extending retaining tabs 124a and 124b. The two retaining tabs 124a and 124b extend from the arcuate section 119. The two retaining tabs 124a and 124b are arranged spaced apart from each other, so that an opening 123 of the retaining leg 116 is formed between the two retaining tabs 124a and 124b, and the opening 123 is thus laterally defined by the retaining tabs 124a and 124b. The opening 123 here has a U-shaped form because it is open at the end of the retaining leg 116 away from the arcuate section 119.
[0037] The two retaining tabs 124a and 124b are each L-shaped, wherein the retaining tabs 124a and 124b are bent at their free ends such that the free end segments 125a and 125b of the retaining tabs 124a and 124b extend bent relative to the main extending plane H of the retaining leg 116. Figures 1 to 6 In the design shown, the free end sections 125a and 125b extend at right angles to the main extension plane H and are therefore parallel to the maneuvering direction B.
[0038] Retaining surfaces 126a and 126b are respectively constructed on the free end sections 125a and 125b of retaining tabs 124a and 124b. The operating element 120, in the open position of the clamping leg 117 of the clamping spring 113, is clamped to these retaining surfaces in such a manner that the operating element 120, in the open position, rests planarly against the two retaining surfaces 126a and 126b, as particularly in… Figure 5 As shown in the diagram. The retaining surfaces 126a and 126b are each oriented toward the arcuate segment 119. In the clamped state, the actuating element 120 can symmetrically rest against the two retaining surfaces 126a and 126b, as shown in the diagram. Figure 4 As can be seen from it.
[0039] To prevent the actuating element 120 from being excessively inserted into the opening 123 of the retaining leg 116, the actuating element 120 may have stop surfaces 127a and 127b on its two opposing sides, respectively. With the aid of these stop surfaces, the actuating element 120 can be supported on the two retaining tabs 124a and 124b in the open position of the clamping leg 117, as particularly in… Figure 4 As shown in the diagram. Stop surfaces 127a and 127b extend parallel to the main extension plane H of the retaining leg 116. The operating element 120 can be supported on the first retaining tab 124a via its first stop surface 127a, and on the second retaining tab 124b via its second stop surface 127b. The two stop surfaces 127a and 127b are approximately located at the center of the operating section 121 of the operating element 120 when viewed along the operating direction B, such that when the operating element 120 is supported on the retaining tabs 124a and 124b with its stop surfaces 127a and 127b, the area of the operating section 121 between the two stop surfaces 127a and 127b can extend into the opening.
[0040] In order to achieve particularly reliable clamping of the operating element 120 on the retaining leg 116 in the open position of the clamping leg 117, the operating element 120 in the design shown here has a contact surface 137 that extends at an angle to the operating direction B of the operating element 120, and the operating element 120 is supported on the arcuate section 119 of the clamping spring 113 by means of the contact surface in the open position of the clamping leg 117 of the clamping spring 113.
[0041] The clamping spring 113 also has a mating leg 128 by which the clamping spring 113 is held and fixed to the busbar 112, particularly to the support section 115 of the busbar 112. The mating leg 128 is connected to the arcuate section 119 and extends from the arcuate section 119 in the operating direction B toward the support section 115 of the busbar 112. The clamping leg 117 is here disposed between the mating leg 128 and the retaining leg 116, as in Figures 1 to 6 As can be seen in the image. The support section 115 has an opening 129 into which the mating leg 128 can extend and hook to secure it to the support section 115.
[0042] To release the clamping leg 117 from the open position, the connecting device 100 further includes a trigger element 130. The trigger element 130 is rotatably supported in the housing 110. The trigger element 130 has a pressure surface 131, which, in order to move the clamping leg 117 of the clamping spring 113 from the open position to the clamping position, can be manipulated by the conductor L to be connected such that the trigger element 130 deflects and, by a deflection movement V, the trigger element 130 applies pressure to the clamping leg 117 of the clamping spring 113, causing the actuating element 120 to release from the clamping position and the clamping leg 117 to deflect from the open position to the clamping position.
[0043] The trigger element 130 has a tab section 132 on which a pressure surface 131 is formed. Furthermore, the trigger element 130 has an eccentrically formed second actuating section 133 that interacts with the clamping leg 117 of the clamping spring 113 to release the clamping leg from the open position. When the trigger element 130 deflects V, the trigger element 130 rolls on the lower side 135 of the clamping leg 117 in the direction pointing towards the trigger element 130 with the outer peripheral surface 134 of the eccentrically formed second actuating section 133, thereby applying pressure to the clamping leg 117.
[0044] The trigger element 130 is rotatably supported on the wall of the housing 110. The trigger element 130 has a shaft element 136 by which it is supported on the housing 110. The shaft element 136 forms a rotation axis about which the trigger element 130 can deflect. The shaft element 136 and the rotation axis thereafter are eccentrically positioned relative to the eccentrically formed second operating section 133.
[0045] exist Figures 1 to 4In this configuration, by pressing the operating element 120 against the upper side 122 of the clamping leg 117 along the operating direction B, and simultaneously clamping the operating element 120 inserted into the opening 123 of the retaining leg 116 by the spring force of the clamping leg 117 in the opposite direction to the operating direction B of the operating element 120, the clamping leg 117 of the clamping spring 113 is held in the open position, thereby clamping the operating element 120 between the clamping leg 117 and the retaining leg 116.
[0046] If the conductor L to be connected is now introduced into the housing 110 through the conductor introduction opening 111 along the introduction direction E, then the conductor L will hit the pressure surface 131 of the trigger element 130, as in Figure 5 As shown in the diagram. Thus, the trigger element 130 deflects along the introduction direction E by means of the conductor L, thereby deflecting the trigger element 130 such that the outer peripheral surface 134 of the eccentrically shaped second operating section 133 of the trigger element rolls on the lower side 135 of the clamping leg 117 and here presses the clamping leg 117 against the operating direction B. The spring force of the clamping leg 117 and the pressure of the trigger element 130 acting on the clamping leg 117 combine to exceed the holding force or clamping force of the operating element 120 between the holding leg 116 and the clamping leg 117, thereby the operating element 120 is pressed out of the clamp in the opposite direction to the operating direction B, and thereby the operating element 120 moves upward in the opposite direction to the operating direction B, thereby the clamping leg 117 can be deflected into the clamping position to clamp the introduced conductor L onto the clamping section 114 of the busbar 112, as shown in Figure 6 As shown in the diagram. Here, the operating element 120 can move so far in the opposite direction of the operating direction B that the operating element 120 can be locked to the housing 110 by the locking nose 138 on the operating element 120. Therefore, in the clamped position, the operating element 120 can be reliably held apart from the clamping leg 117 of the clamping spring 113.
[0047] Another design scheme for the connecting device 100 is... Figures 7 to 11 As shown in the image. (and) Figures 1 to 6 The main difference in the connecting device shown is that the clamping spring 113 does not have a mating leg; instead, the clamping spring 113 is held on the clamping section 114 of the busbar 112 by its retaining leg 116. Here, the retaining leg 116 is constructed so long in the main extension plane H that it surrounds the clamping section 114 in such a way that the clamping section 114 of the busbar 112, like the clamping leg 117 of the clamping spring 113, extends through the opening 123 in the retaining leg 116. The conductor L to be connected also extends into the opening 123. The opening 123 is not U-shaped here, but window-like and thus closed on all sides. The free end section 139 of the retaining leg 116 bends out from the main extension plane H and clamps relative to the clamping section 114 of the busbar 112.
[0048] and Figure 7 The design schemes shown are different, in Figure 8 In the design shown, the retaining leg 116 has two retaining tongues 140a and 140b in the area of its opening 123. The operating element 120 can clamp onto the retaining tongues when the clamping leg 116 of the clamping spring 113 is in the open position. Figure 7 As can be seen in the image. The retaining tongues 140a and 140b are constructed on two opposing edge regions of the opening 123 by cutting and bending them into desired shapes from the edge regions of the material surrounding the opening 123 of the retaining leg 116. The retaining tongues 140a and 140b are each constructed in an arc shape, thus forming an introduction ramp for introducing the actuating element 120 into the opening 123 along the two retaining tongues 140a and 140b.
[0049] exist Figures 9 to 11 In this process, by pressing the operating element 120 against the upper side 122 of the clamping leg 117 along the operating direction B, and simultaneously clamping the operating element 120 introduced into the opening 123 of the retaining leg 116 by the spring force of the clamping leg 117 in the opposite direction to the operating direction B of the operating element 120, the clamping leg 117 of the clamping spring 113 is held in the open position, so that the operating element 120 is clamped between the clamping leg 117 and the retaining leg 116.
[0050] If the conductor L to be connected is now introduced into the housing 110 through the conductor introduction opening 111 along the introduction direction E, then the conductor L will touch the pressure surface 131 of the trigger element 130, as in Figure 10 As shown in the diagram. Thus, the trigger element 130 deflects along the introduction direction E by means of the conductor L, thereby performing a deflection movement V such that the outer circumferential surface 134 of the eccentrically shaped second operating section 133 of the trigger element rolls on the lower side 135 of the clamping leg 117 and here presses the clamping leg 117 in the opposite direction of the operating direction B. The spring force of the clamping leg 117 and the pressure of the trigger element 130 acting on the clamping leg 117 combine to exceed the holding force or clamping force of the operating element 120 between the holding leg 116 and the clamping leg 117, thereby the operating element 120 is pressed out of the clamp in the opposite direction of the operating direction B, and thereby the operating element 120 moves upward in the opposite direction of the operating direction B, so that the clamping leg 117 can be deflected into the clamping position to clamp the introduced conductor L onto the clamping section 114 of the busbar 112, as shown in the diagram. Figure 11 As shown in the image.
