Definitions
- Terminal device for connecting an electrical conductor
- the invention relates to a terminal device for connecting an electrical conductor according to the preamble of claim 1.
- Such a terminal device comprises a housing which has a plug-in opening for inserting an electrical conductor.
- a spring element is arranged on the housing, which has a clamping leg for acting on an electrical conductor inserted into the plug-in opening.
- a lever element which has an actuating section for acting on the clamping leg of the spring element and a lever head, can also be pivoted relative to the housing. The lever element can be pivoted to adjust the clamping leg relative to the housing between a first pivoting position and a second pivoting position along a pivoting direction in order in this way to move the clamping leg between a clamping position (in which the clamping leg can have a clamping effect on an electrical conductor inserted into the plug-in opening). and a release position (in which a receiving space within the housing is released for inserting or releasing an electrical conductor).
- Such a terminal device enables an electrical conductor to be connected in a simple, convenient, tool-free manner.
- a terminal device can serve, for example, as a block terminal for potential distribution.
- Such a terminal device can, however, also be used on another electrical or electronic device, for example a series terminal or the like.
- the spring element can be actuated by actuating the lever element and adjusted between different positions.
- a user can act on the lever head and thereby adjust the lever element between its clamping position and its release position, so that in the clamping position an electrical conductor inserted into the plug-in opening can be clamped and thus mechanically locked and electrically contacted; inserted into the plug-in opening or - if a conductor has already been inserted into the plug-in opening - the conductor can be removed from the plug-in opening.
- a lever element is mounted on a housing such that it can pivot about an axis and can be actuated in order to adjust a clamping leg of a spring element between different positions in this way.
- an actuating element in the form of a lever is pivotably mounted on a housing and connected to a leg of a spring element in such a way that the leg is adjusted when the actuating element is adjusted.
- the object of the present invention is to provide a clamping device which, with a compact design, can be constructed simply and inexpensively and can be operated conveniently and reliably.
- the clamping device has a guide device which is arranged on the housing and has a guide surface extending along the pivoting direction, the lever element having a sliding guide section formed on the lever head, which is slidably guided on the guide surface of the guide device in such a way that the sliding guide section is pivoted of the lever element is moved between the first pivot position and the second pivot position along the pivot direction on the guide surface.
- the lever element is guided on a guide surface of the guide device via the lever head.
- the guide surface thus defines a movement path for the lever head and thus a pivoting movement of the lever element.
- the lever element is guided via the guide surface of the guide device on the lever head, pivoting of the lever element via a bearing axis can be dispensed with.
- a movement path of the lever element is predetermined by the guide surface of the guide device, so that the lever element is moved when the lever head is pivoted with sliding guidance.
- the clamping device can be constructed compactly without this the lever element protrudes, for example, into a receiving space in which an electrical conductor inserted into the plug-in opening is received.
- actuation by a user can take place via the lever head.
- a user can, for example, take hold of the lever head in order to adjust the lever element between a first pivot position and a second pivot position relative to the housing.
- the lever element can be pivoted about a pivot axis relative to the housing.
- the lever head is here arranged radially to the pivot axis outside the actuating section and is thus radially spaced from the actuating section.
- the lever head can be formed, for example, at an end of the lever element remote from the radially inner actuating section.
- the guide surface on which the sliding guide section of the lever head is guided is curved about the pivot axis.
- the guide surface thus specifies a movement path about the pivot axis, along which the lever head moves when the lever element is adjusted with sliding guidance over the sliding guide section.
- the lever head can be arranged, for example, on a side of the guide surface facing away from the actuating section.
- the guide surface can be formed, for example, on an outer wall section of the housing and point outwards.
- the lever head can, for example, be arranged outside the housing so that the lever head can be actuated easily and conveniently by a user and moved to adjust the clamping leg of the spring element.
- the lever element has an opening through which the guide device engages.
- the opening can, for example, be delimited at one end by the actuating section and at another end by the lever head, with, for example, two legs extending between the lever head and the actuating section, between which the opening is enclosed.
- the guide device can for example be shaped as a finger on the housing, the guide surface being shaped, for example, on a side of the finger facing away from the actuating section, while on a side of the finger facing the actuating section, for example, the spring element is supported with a support leg.
- the sliding guide section is formed by a step on the lever head.
- the step can be formed, for example, at a transition between a leg of the lever element and the lever head and can, for example, point towards the (virtual) pivot axis about which the spring element can pivot.
- the lever head has two sliding guide sections which extend parallel to one another, are spaced apart from one another along the pivot axis and are guided on parallel guide surfaces of the guide device.
- the lever head has a stop section for stopping against a stop surface of the guide device in the first pivot position or the second pivot position.
- a pivoting movement of the lever head is thus limited via the stop section in that the stop section strikes a stop surface of the guide device in one of the pivot positions and thus cannot be pivoted beyond the respective pivot position.
- the stop section can be formed, for example, radially outside the sliding guide section on the lever head, wherein the stop section can be offset along the pivot axis relative to the sliding guide section.
- the stop section can for example be formed between the sliding guide sections.
- the lever head has a detent for locking with a counter-detent formed on the guide device in the first pivot position or the second pivot position.
- the lever element can thus lock in the first pivot position or the second pivot position in that the lock of the lever head comes into (positive) engagement with the counter lock of the guide device.
- the locking connection can be released by a user acting on the lever head with a force that exceeds a predetermined release force, so that the lever element is held locked in the respective pivot position, but the locking connection can easily be adjusted by a user Lever element and thus the clamping leg of the spring element can be released.
- the actuation section of the lever element is received in a receiving pocket formed on the clamping leg.
- the actuating section acts in a defined manner on the clamping leg in that the actuating section is moved in the receiving pocket when the lever element is adjusted.
- the receiving pocket can be formed, for example, by a curved section of the clamping leg, on which the clamping leg is bent, for example by an angle between 60 ° and 120 °, for example approximately 90 °, and in which the actuating section engages, so that the actuating section when the lever element is pivoted is rotatable in the receiving pocket.
- the lever element has an end section which is remote from the lever head and which is supported on a housing section of the housing.
- the end section can be formed, for example, at a radially inner end of the lever element and provide support with respect to the housing, but without the end section necessarily providing a pivot bearing.
- a contacting element is arranged on the housing, which is also referred to as a current bar and is used for contacting an electrical conductor inserted into the plug-in opening. If an electrical conductor is inserted into the plug-in opening, the clamping leg of the spring element acts on the electrical conductor in a clamping position in order to clamp it to the contacting element, so that the electrical conductor is mechanically locked in the plug-in opening and is also in electrical contact with the contacting element. For example, a potential distribution between different connections of the terminal device can be provided via the contacting element.
- an electrical contact element for establishing a plug connection can be electrically connected to the contacting element, so that an electrical conductor inserted into the plug-in opening can be electrically connected to the contact element by making contact with the contacting element.
- the contacting element has a latching element which is latched to the spring element.
- the spring element can, for example, have a latching opening at one end of a support leg supported on the housing, into which the latching element of the contacting element engages, so that the contacting element is connected to the spring element in a latching and thus form-fitting manner.
- the contacting element can be latched to the housing, wherein the contacting element can be latched for this purpose, for example, with a latching device of a first housing part and a second housing part blocks the latching connection of the contacting element with the first housing part via a locking section.
- the latching device of the first housing part can, for example, have one or more latching legs, the locking section acting on the one or more latching legs to prevent the one or more latching legs from being deflected and thus to block a loosening of the latching connection between the contacting element and the housing .
- the clamping device can have one or more plug-in openings and, accordingly, one or more spring elements and one or more lever elements, with each plug-in opening preferably being assigned a spring element and a lever element. If the terminal device has several plug-in openings and correspondingly several spring elements and lever elements, then several electrical conductors can be connected to the terminal device in order, for example, to provide a potential distribution via the terminal device.

- Embodiment is formed by housing parts 10, 11, which are used to form the
- housing are locked together.
- plug-in openings 100 are formed, which enable an electrical conductor 2 to be plugged in along a plug-in direction E with a stripped conductor end 20 in order to make electrical contact with the electrical conductor 2 with the terminal device 1.
- three plug-in openings 100 are formed on each side of the housing facing away from one another, so that three electrical conductors 2 can be plugged into each side of the housing.
- a potential distribution can be provided via the terminal device 1, so that electrical conductors 2 connected to the terminal device 1 are connected to the same potential, for example a ground potential, via the terminal device 1.
- a lever element 12, a guide device 13 and a spring element 14 are assigned to each plug-in opening 100, as can be seen in conjunction with FIGS. 1 and 2 with FIGS. 3 and 4.
- the guide devices 13 are shaped like fingers on the housing part 11 and serve to guide the respectively assigned lever element 12.
- the lever element 12 can act on the spring element 14 to move the spring element 14, in particular a clamping leg 142 of the spring element 14, between different To adjust positions in order to mechanically lock an electrical conductor inserted into a plug-in opening 100 in the plug-in opening 100 and also to make electrical contact or to release it again from the plug-in opening 100, as will be described below.
- the lever element 12 which is shown in a separate illustration in FIG. 5, has a lever head 120 which is arranged outside the housing, as can be seen, for example, from FIGS. 1 and 2.
- the lever head 120 is connected via two legs 123 to an actuating section 125 extending transversely between the legs 123, which is designed to act on the clamping leg 142 of the spring element 14 and, as can be seen from FIGS. 6 and 7, in a receiving pocket 145 on the Clamp leg 142 rests.
- the lever element 12 forms an opening 126, with which the lever element 12 is attached to an associated guide device 13 on the housing part 11 in such a way that the guide device 13 extends through the opening 126 in the form of the finger formed on the housing part 11, as shown, for example, in FIG Fig. 3 and 4 can be seen.
- the lever head 120 is slidably guided on the guide device 13, so that a movement path along an adjustment direction V of the lever element 12 to the housing is predetermined via the guide device 13.
- the lever element 12 forms slide guide sections 122 in the form of steps at the transitions between the legs 123 and the lever head 120, which protrude inward from the legs 123 and slide onto associated ones Guide surfaces 131 rest on the guide device 13.
- the guide surfaces 131 of the guide device 13 extend in parallel on edges of the guide device 13 facing away from one another and are curved about a pivot axis S about which the lever element 12 can be pivoted relative to the housing.
- the sliding guide sections 122 are correspondingly also on the lever element
- the guide surfaces 131 in cooperation with the sliding guide sections 122 on the lever head 120, define a path of movement of the lever element 12 along the pivot direction V.
- the lever head 120 is attached to the guide device along the adjustment direction V
- the lever head 120 is spaced apart from the actuating section 125 radially to the pivot axis S.
- the guide surfaces 131 of the guide device 13 point outwards, and the lever head 120 is slidably guided outside the housing, so that a user can act on the lever head 120 in order to adjust the lever element 12 relative to the housing.
- the actuation section 125 is formed in the area of end sections 124 between the legs 123.
- the lever element 12 is supported on housing sections 102 on both sides within the housing via the end sections 124, as can be seen in particular from FIGS. 10 and 12, so that the end sections 124 together with the guide device 13 cause the lever element 12 to pivot.
- a stop section 121 is formed on the lever head 120 between the sliding guide sections 122, which stop section 121 abuts in the pivoted position of the lever element 12 shown in FIG. 9 a stop surface 130 of the guide device 13 rests, which is shaped as a raised section between the guide surfaces 131.
- the impact of the stop section 121 on the stop surface 130 has the effect that the spring element 12 cannot be pivoted beyond the pivot position shown in FIG. 9 to the housing and thus cannot be moved out of the area of the guide device 13.
- Each spring element 14 has a clamping leg 142 which is connected to a support leg 141 via a curved section 140.
- the curved section 140 and the support leg 141 are supported on a support section 132 of the guide device 13 facing away from the guide surfaces 131 and the stop surface 130, so that the spring element 14 is fixed to the finger of the housing 11 forming the guide device 13.
- the spring element 14 is held in contact with the support section 132 via the associated lever element 12.
- a contacting element 16 in the form of a current bar is connected to the housing part 11 via latching devices 15, which has a flat bar section 160 and latching elements 161 (each associated with a pair of spring elements 14).
- the contacting element 16 is positively connected to the housing part 11 via the latching devices 15.
- the contacting element 16 engages between ends 143 which are formed on the support legs 141 of adjacent spring elements 14 (which are assigned to mutually opposite plug-in openings 100), and engages in latching openings 144 at the ends 143, so that the contacting element 16 is positively locked with the spring elements 14 is in connection.
- the locking connection of the contacting element 16 to the housing part 11 is also blocked by - as can be seen from FIG. 11 - the housing part 10 with housing sections 101 in the form of Ribs between latching legs 150 of latching devices 15 engages and thus prevents deflection of latching legs 150 and thus loosening of the connection between latching devices 15 and contacting element 16.
- the spring elements 14 assigned to the individual plug-in openings 100 are attached to the housing part 11 in such a way that the spring elements 14 each with the support leg 141 and the curved section 140 close to the support surface 132 formed on the rear of the assigned guide device 13 come lying down.
- the lever elements 12 are then attached to the guide devices 13 assigned to the plug-in openings 100 and brought into the position shown in FIG. 7, so that above this each spring element 14 is fixed on the housing part 11 with the deflection of the clamping leg 142.
- the contacting element 16 in the form of the current bar is attached to the housing part 11 by the latching devices 15 being brought into engagement with the contacting element 16 and also the latching elements 161 of the contacting element 16 in each case between the ends 143 of adjacent ones Spring elements 14 come to rest.
- the lever elements 12 can now be pivoted into the position shown in FIG. 9 relative to the housing part 11.
- the clamping legs 142 of the spring elements 14 follow the actuation sections 125 of the lever elements 12 due to the elasticity of the spring elements 14 and come into contact with a respectively assigned stop 162 on the contacting element 16, via which an end position of the clamping leg 142 is defined.
- the housing By attaching the housing part 10, as can be seen from Fig. 10, the housing is completed, whereby when the housing part 10 is attached, the housing sections 101 come into locking connection with the locking devices 15, as can be seen from FIG. 11, and thereby the connection of the Contacting element 16 is secured to housing part 11.
- the terminal device 1 is thus ready for use and can be used for a potential distribution on connected electrical conductors.
- each spring element 14 protrudes in a clamping position when the lever element 12 is not actuated into an associated receiving space 17 of the housing in order to act on an electrical conductor 2 inserted into the respectively associated plug-in opening 100 in the clamping position (FIG. 10).
- the clamping leg 122 can be moved out of the clamping position by actuating the lever element 12, as a result, the actuating section 125 acts on the clamping leg 142 and moves the clamping leg 142 into a release position in which the receiving space 17 is released (see the spring element 14 shown on the right in FIG. 12).
- an electrical conductor 2 can be inserted essentially without force into the respectively assigned plug-in opening 100, or an electrical conductor 2 plugged into the plug-in opening 100 can be removed from the plug-in opening 100 and thus detached from the terminal device 1.
- the actuating section 125 moves in the receiving pocket 145 formed on the clamping leg 142 by the actuating section 125 pivoting in the receiving pocket 145 and, due to the change in position of the actuating section 125, moving the clamping leg 142 by pivoting the lever element 12.
- lever element 12 When pivoting, the lever element 12 is also supported via its end sections 124 on the legs 123 on the housing section 102 of the housing part 10, as can be seen in the transition from FIG. 10 to FIG. 12.
- a lever element 12 is pivotably arranged on a housing part 11 and for this purpose is guided via a lever head 120 with a sliding guide section 122 on the inside of the lever head 120 on a curved guide surface 131 of a guide device 13 formed on the housing part 11 .
- the spring element 12 can be pivoted between different pivot positions relative to the housing part 11 in order to act on a clamping leg 142 of a spring element 14 and to adjust it between a clamping position (FIG. 16) and a release position (FIG. 18).
- a contacting element 16 is fixed on the housing part 11 and is electrically connected to a contact element 18 in the form of a contact pin.
- An electrical conductor can be inserted into a plug-in opening 100 of the housing part 11 in order to connect the electrical conductor to the contact element 18 via the terminal device 1.
- the lever element 12 has a (single) leg 123 which connects the lever head 120 to an actuating section 125.
- the lever element 12 is thus open on one side, the leg 123 encompassing the guide device 13 formed on the housing part 11 and in this way the Lever head 120 arranged outside the guide device 13 connects to the actuating section 125 arranged inside the guide device 13.
- the guide device 13 specifies a movement path for pivoting the lever element 12 along a pivoting direction V via the guide surface 131 formed thereon.
- the guide surface 131 is curved for this purpose and thus extends around a (virtual) pivot axis of the lever element 12.
- a detent 127 is formed on the sliding guide section 122 on the inside of the lever head 120, which in the pivoted position of the lever element 12 shown in FIGS. 17 and 18 engages with a counter detent 133 on the guide surface 131 of the guide device 13 and the lever element 12 thus engages the guide device 13 locked.
- the lever element 12 is thus locked in the end position to the guide device 13 shown in FIGS. 17 and 18, whereby a user can act on the lever element 12 and release the lever element 12 from the latching position by applying sufficient force.
- the lever element 12 is additionally supported on a housing section 102 of the housing part 11 via an end section 124 on the leg 123, as can be seen from FIGS. 13 and 14.
- the functioning of the clamping device 1 of the exemplary embodiment according to FIGS. 13 to 18 is analogous to the exemplary embodiment according to FIGS. 1 to 12.
- the clamping leg 142 of the spring element 14 can be moved from a clamping position (FIG. 16) into a release position (FIG. 18), in that when the lever element 12 is pivoted, the actuating section 125 acts on the clamping leg 142 and moves it out of the area of a receiving space 17 within the housing part 11, so that an electrical conductor or an inserted conductor is plugged into the receiving space 17 via the plug-in opening 100 can be removed from the receiving space 17.
- a clamping device of the type described can be used in completely different ways to connect an electrical conductor to an associated assembly to connect.
- a terminal device can implement a block terminal, for example, but can also be used on other electrical devices, for example series terminals or the like.
