Description

Terminal device for connecting electrical conductors

Technical Field

The present invention relates to a terminal device for connecting electrical conductors according to the preamble of claim 1.

Background

The terminal device comprises a housing having a socket for insertion of an electrical supply conductor. A spring element is arranged on the housing and has a clamping foot which acts on the electrical conductor inserted into the socket. Furthermore, a lever element can be pivoted relative to the housing, which lever element has an actuating section which acts on the clamping foot of the spring element and the lever head. The lever element can be pivoted in the pivoting direction relative to the housing between a first pivoted position and a second pivoted position for adjusting the clamping foot in such a way that the clamping foot can be adjusted between a clamping position (in which the clamping foot can act in a clamping manner on an electrical conductor inserted into the socket) and a release position (in which the receiving space inside the housing is released for inserting or separating the electrical conductor).

Such a terminal device enables the connection of electrical conductors in a simple, convenient and tool-free manner. Such a terminal device can be used, for example, as a distribution box for potential distribution. However, the terminal device may be used for another electric or electronic apparatus, such as a terminal block or the like.

In a terminal device of the type described, the spring element can be actuated and adjusted between different positions by actuating the lever element. To this end, the user can act on the lever head such that the lever element is adjusted between its clamping position and its release position, so that the electrical conductor inserted into the socket is clamped in the clamping position and is thus mechanically locked and electrically contacted, while in the release position the conductor is inserted into the socket without application of force or, in the event that the conductor has been inserted into the socket, can be removed again from the socket.

In the terminal device disclosed in DE 102015104625 a1, a lever element is pivotably supported on a housing and can be actuated in order to adjust a clamping foot of a spring element between different positions in this way.

In the terminal device disclosed in DE 102016108826 a1, the actuating element is pivotably mounted on the housing in the form of a lever and is connected to the limb of the spring element in such a way that the limb is adjusted when the actuating element is adjusted.

Disclosure of Invention

The object of the invention is to provide a terminal device which is constructed in a simple and cost-effective manner while being compact in design and which can be handled easily and reliably.

The solution of the invention to achieve the above object is the subject matter with the features of claim 1.

In this case, the terminal device has a guide device arranged on the housing, which has a guide surface extending in the direction of deflection, wherein the lever element has a sliding guide section formed on the lever head, which is guided in a sliding manner on the guide surface of the guide device, so that the sliding guide section moves on the guide surface when the lever element is deflected in the direction of deflection between the first deflected position and the second deflected position.

In the terminal device, the lever element is guided on a guide surface of the guide device by the lever head. The guide surface thus defines a trajectory of movement of the head and thus a yaw movement of the lever element. When the lever element is adjusted, the lever head slides along the guide surface, so that the lever element is deflected and the actuating section is adjusted to adjust the clamping foot of the spring element.

The lever element is guided on the head by the guide surfaces of the guide device, so that a pivot bearing of the lever element by the bearing shaft can be dispensed with. The path of movement of the lever element is predetermined by the guide surfaces of the guide device, so that the lever element is moved by the sliding guide of the club head during a deflection. Since the lever element does not have to have a bearing shaft which is supported on the housing, the terminal device can be constructed more compactly, for example, without the lever element having to project into a receiving cavity which receives an electrical conductor which is inserted into the socket.

The user can, for example, maneuver the club head (without tools). A user may, for example, grasp the club head to adjust the lever member between the first deflected position and the second deflected position relative to the housing.

In one embodiment, the lever element can be pivoted about a pivot axis relative to the housing. In the process, the rod head is arranged radially outside the actuating section relative to the pivot axis and is thus spaced radially apart from the actuating section. The shaft head can be formed, for example, on the end of the lever element remote from the radially inner actuating section.

In one embodiment, the guide surface on which the sliding guide section of the shaft head is guided is curved about the pivot axis. The guide surface thus defines a path of movement about the pivot axis along which the lever head is moved by the sliding guide implemented by the sliding guide section when the lever element is adjusted.

The shaft head can be arranged, for example, on the 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 faces outward. The lever head can, for example, be arranged outside the housing, so that a user can simply and conveniently manipulate and move the lever head to adjust the grip foot of the spring element.

In one embodiment, the lever element has an opening through which the guide passes. The opening can be bounded at one end by the actuating section and at the other end by the club head, for example, with two feet extending between the club head and the actuating section, the opening being enclosed between the two feet. The guide device can be formed, for example, as a finger on the housing, wherein the guide surface is formed, for example, on the side of the finger facing away from the actuating section, while, for example, the spring element is supported with a support leg on the side of the finger facing toward the actuating section. When the lever element is adjusted, the guide device is moved in the opening, so that the lever head slides along a guide surface formed on the guide device, so that the lever element is moved in a defined guided manner relative to the housing.

In one solution, the sliding guide section is formed by a step on the club head. These steps can be formed, for example, at the transition between the foot of the lever element and the lever head and can, for example, be oriented toward a (virtual) pivot axis about which the spring element is pivoted.

In one embodiment, the rod head has two sliding guide sections which are 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.

In one embodiment, the head has a stop section for stopping on a stop surface of the guide in the first or second pivoted position. The pivoting movement of the club head is therefore limited by the stop section, in that the stop section stops in one of the pivot positions on the stop face of the guide, so that it cannot pivot beyond the respective pivot position. The stop section can be formed, for example, radially outside the sliding guide section on the shaft head, wherein the stop section can be offset from the sliding guide section along the pivot axis.

If the head has two sliding guide sections parallel to one another, the stop section can be formed, for example, between the sliding guide sections.

In one embodiment, the head has a catch for engaging with a mating catch formed on the guide in the first or second deflected position. The lever element can thus be latched in the first or second pivoted position, in particular by the latching of the head engaging with a mating latching (form-locking) of the guide device. Wherein the snap connection is disengageable in such a way that the user exerts a force on the lever head which exceeds a predetermined disengagement force, so that the lever element remains snapped in the respective deflected position, but the user can easily disengage this snap connection to adjust the lever element and the grip foot of the spring element.

In one embodiment, the actuating section of the lever element is received in a receiving groove formed on the clamping foot. The actuating section thereby acts on the clamping foot in a defined manner, in particular in such a way that it moves in the receiving groove when the lever element is adjusted. The receiving groove can be formed, for example, by a curved section of the clamping foot, on which section the clamping foot is curved, for example, at an angle of 60 ° to 120 °, for example, at an angle of approximately 90 °, and the actuating section engages in said section, so that the actuating section can be rotated in the receiving groove when the lever element is pivoted.

In one embodiment, the lever element has a distal portion remote from the shaft head, which is supported on a housing portion of the housing. The end section can, for example, be molded onto the radially inner end of the lever element and forms a support relative to the housing, but the end section does not need to provide a pivot bearing.

In one solution, contact elements, also referred to as current bars, are arranged on the housing and are intended to be in contact with an electrical conductor inserted into the socket. If the electrical conductor is inserted into the socket, the clamping feet of the spring element act on the electrical conductor in the clamping position to clamp this electrical conductor together with the contact element, so that the electrical conductor is mechanically locked in the socket and, in addition, is in electrical contact with the contact element. For example, a potential distribution can be provided between the different connections of the terminal device via the contact elements. Additionally or alternatively, the electrical contact element can be electrically connected with the contact element to establish a plug-in connection, so that an electrical conductor inserted into the socket can be electrically connected with the contact element by contacting the contact element.

In one solution, the contact element has a snap element that snaps with the spring element. The spring element can have, for example, a bayonet on the end of the support leg supported on the housing, into which bayonet the latching element of the contact element is latched, so that the contact element is connected in a latching and thus form-fitting manner to the spring element.

In addition or alternatively, the contact element can engage with the housing, wherein for this purpose the contact element can engage with a catch device of the first housing part, and the second housing part blocks the catch connection of the contact element with the first housing part by means of the blocking section. The snap means of the first housing part may for example have one or more snap legs, wherein the blocking section acts on the one or more snap legs to prevent the one or more snap legs from deflecting, thereby preventing the snap connection between the contact element and the housing from separating.

The terminal device may have one or more sockets and, respectively, one or more spring elements and one or more lever elements, wherein preferably each socket corresponds to one spring element and one lever element. If the terminal arrangement has a plurality of sockets and, correspondingly, a plurality of spring elements and a plurality of lever elements, then a plurality of electrical conductors can be connected to the terminal arrangement, for example, in order to provide potential distribution via the terminal arrangement.

Detailed Description

The terminal device 1 in the form of a distribution box shown in the exemplary embodiment in fig. 1 to 12 has a housing which is formed in the exemplary embodiment shown by

housing parts

10, 11 which are connected in a snap-fit manner to form a housing. In this case, sockets 100 are formed on the housing part 10 (on the sides of the housing facing away from each other), which sockets allow the electrical conductors 2 to be plugged together in each case in the plugging direction E with the stripped conductor ends 20, so that the electrical conductors 2 are electrically contacted with the terminal device 1.

In the exemplary embodiment shown in fig. 1 to 12, three sockets 100 are formed on the sides of the housing facing away from each other, so that three electrical conductors 2 can be plugged into each side of the housing. The potential distribution can be achieved by the terminal device 1 in such a way that the electrical conductors 2 connecting the terminal device 1 can be connected to the same potential, for example ground potential, by the terminal device 1.

As can be seen from fig. 1, 2, 3 and 4, each socket 100 corresponds to a lever element 12, a guide 13 and a spring element 14. The guide means 13 are formed in the housing part 11 in the manner of fingers and serve to guide the corresponding lever element 12. The spring element 14 can be acted upon by the lever element 12 in order to adjust the spring element 14, in particular the clamping feet 142 of the spring element 14, between different positions, to mechanically lock an electrical conductor inserted into the socket 100 in the socket 100 and to make electrical contact or to detach it again from the socket 100, as will be explained below.

The lever element 12, which is shown in a separate view in fig. 5, has a head 120, which is arranged outside the housing, as shown, for example, in fig. 1 and 2. The club head 120 is connected via two legs 123 to an actuating section 125 extending transversely between the legs 123, which is suitable for acting on the legs 142 of the spring element 14 and, for this purpose, engages in a receiving groove 145 on the legs 142, as shown in fig. 6 and 7.

The lever element 12 forms an opening 126 by means of which the lever element 12 is attached to a corresponding guide means 13 on the housing part 11 in such a way that, as shown in fig. 3 and 4, the guide means 13 extend through the opening 126 in the form of a finger formed on the housing part 11.

The rod head 120 is guided in a sliding manner on the guide 13, so that a movement path in the adjustment direction V of the lever element 12 relative to the housing is predetermined by the guide 13. As can be seen from the individual view of the lever element 12 shown in fig. 5, the lever element 12 forms, at the transition between the foot 123 and the shaft head 120, sliding guide sections 122 in the form of steps which project inwardly from the foot 123 and bear in a sliding manner against corresponding guide surfaces 131 on the guide device 13. The guide surfaces 131 of the guide 13 extend parallel to the edges of the guide 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. Accordingly, the sliding guide section 122 is also bent on the lever element 12, so that the sliding guide section 122 rests in a planar manner on the guide surface 131 of the guide 13 and slides on the guide surface 131 when the lever element 12 is deflected.

The guide surface 131 defines a path of movement of the lever element 12 in the direction of deflection V in cooperation with the sliding guide section 122 on the shaft head 120. When the lever element 12 is pivoted relative to the housing, the lever head 120 is moved in the pivoting direction V on the guide device 13 in such a way that the sliding guide section 122 slides along the guide surface 131, so that the actuating section 125 is adjusted relative to the clip foot 142, as a result of which the clip foot 142 is moved within the housing.

The club head 120 is spaced from the manoeuvring section 125 in a radial direction relative to the yaw axis S. The guide surface 131 of the guide means 13 faces outwards and the club head 120 is guided in a sliding manner outside the housing, so that the user can act on the club head 120 to adjust the lever element 12 with respect to the housing.

The actuating section 125 is formed in the region of the end section 124 between the legs 123. As shown in particular in fig. 10 and 12, the lever element 12 is supported on the housing section 102 on both sides inside the housing by the end sections 124, so that the end sections 124 together with the guide 13 form a pivot bearing for the lever element 12.

Between the sliding guide sections 122, a stop section 121 is formed on the head 120, which in the pivoted position of the lever element 12 shown in fig. 9 rests against a stop surface 130 of the guide 13, which is formed as a projection between the guide surfaces 131. The stop section 121 rests on the stop surface 130, so that the spring element 12 cannot be pivoted relative to the housing beyond the pivot position shown in fig. 9 and therefore cannot be moved out of the region of the guide 13.

Each spring element 14 has a clamping foot 142, which is connected to the supporting limb 141 via the bending section 140. The curved section 140 and the support leg 141 are supported on the support section 132 of the guide device 13 facing away from the guide surface 131 and the stop surface 130, so that the spring element 14 is fixed relative to the fingers of the housing 11 forming the guide device 13.

The spring element 14 is held against the support section 132 by the corresponding lever element 12.

As fig. 8 and 9 show, the contact element 16 in the form of a current bar having a planar bar section 160 and a latching element 161 (corresponding to a pair of spring elements 14, respectively) is connected to the housing part 11 by means of a latching device 15. The contact element 16 is connected to the housing part 11 by means of a snap-in connection 15 in a form-fitting manner. The contact elements 16 are clipped by each snap-in element 161 between the ends 143 formed on the supporting limbs 141 of adjacent spring elements 14 (corresponding to oppositely arranged receptacles 100) and into the notches 144 on the ends 143, so that the contact elements 16 are connected positively to the spring elements 14.

Furthermore, in the mounting position in which the housing part 10 is snapped into the housing part 11, the snap connection between the contact element 16 and the housing part 11 is blocked, in particular, as shown in fig. 11, the housing part 10 is snapped between the snap legs 150 of the snap means 15 with the housing sections 101 in the form of ribs, as a result of which the deflection of the snap legs 150 is blocked and the connection between the snap means 15 and the contact element 16 is blocked.

The sequence of mounting the terminal device 1 can be explained in connection with fig. 6-10.

First, as shown in fig. 6, the spring element 14 corresponding to each socket 100 is attached to the housing part 11 in such a way that the spring element 14 rests with the support legs 141 and the curved sections 140, respectively, on the support surface 132 formed on the rear side of the corresponding guide device 13.

Subsequently, the lever element 12 is attached to the guide means 13 corresponding to the socket 100 and brought into the position shown in fig. 7, whereby each spring element 14 is fixed on the housing part 11 by the deflection of the clamping feet 142.

As shown in fig. 8, only the contact elements 16 in the form of current bars are attached to the housing part 11, in particular by the snap-in means 15 snapping in with the contact elements 16, and furthermore the snap-in elements 161 of the contact elements 16 are situated between the tips 143 of adjacent spring elements 14.

The lever member 12 can now be pivoted relative to the housing part 11 to the position shown in fig. 9. In the process, the leg 142 of the spring element 14 follows the actuating section 125 of the lever element 12 on the basis of the elasticity of the spring element 14 and comes into abutment with a corresponding stop 162 on the contact element 16, by means of which the end position of the leg 142 is defined.

The housing is completed by the attachment housing part 10, as shown in fig. 10, wherein upon attachment of the housing part 10, as shown in fig. 11, the housing section 101 is in blocking connection with the snap means 15, thereby ensuring the connection of the contact element 16 with the housing part 11. The terminal device 1 is therefore ready for use and can be used for potential distribution on the electrical conductors connected thereto.

In the non-actuated state of the lever element 12, the clamping foot 142 of each spring element 14 projects into the corresponding receiving cavity 17 of the housing in the clamping position in order to act on the electrical conductor 2 inserted into the corresponding socket 100 in this clamping position (fig. 10). The clamping foot 122 can be moved out of the clamping position by actuating the lever element 12, whereby the actuating section 125 acts on the clamping foot 142 and moves the clamping foot 142 into the release position, in which the receiving space 17 is released (see the spring element 14 shown on the right in fig. 12). In the release position, the electrical conductor 2 may be inserted into the corresponding socket 100 substantially without force, or the electrical conductor 2 inserted into the socket 100 may be removed from the socket 100, thereby being separated from the terminal device 1.

When the lever element 12 is deflected, the actuating section 125 moves in a receiving groove 145 formed on the clamping foot 142, in that the actuating section 125 is deflected in the receiving groove 145 and the clamping foot 142 is moved on the basis of the change in position of the actuating section 125 as a result of the deflection of the lever element 12.

Furthermore, it can be seen from the transition from fig. 10 to fig. 12 that, during pivoting, the lever element 12 is supported by its end section 124 on the leg 123 on the housing section 102 of the housing part 10.

In a further exemplary embodiment shown in fig. 13 to 18, the lever element 12 is arranged on the housing part 11 so as to be pivotable, for which purpose the lever head 120 is guided 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 in turn be pivoted relative to the housing part 11 between different pivoted positions in order to act on a foot 142 of the spring element 14 and to adjust this foot between a clamping position (fig. 16) and a release position (fig. 18).

In the exemplary embodiment shown in fig. 13 to 18, the contact element 16 is fixed to a housing part 11, which is electrically connected to a contact element 18 in the form of a contact pin. The electrical conductor can be inserted into the socket 100 of the housing part 11 to connect the electrical conductor to the contact element 18 via the terminal device 1.

In the illustrated embodiment, the lever element 12 has a (single) foot 123 that connects the club head 120 with the operating section 125. The lever element 12 is therefore open on one side, with the leg 123 engaging around the guide device 13 formed on the housing part 11, and in this way connects the head 120 arranged outside the guide device 13 to the actuating section 125 arranged inside the guide device 13.

The guide device 13 presets a path of movement of the pivoting of the lever element 12 in the pivoting direction V by means of a guide surface 131 formed thereon. For this purpose, the guide surface 131 is curved so as to extend around the (virtual) pivot axis of the lever element 12.

On the sliding guide section 122, a catch 127 is formed on the inside of the head 120, which catch engages in a mating catch 133 on the guide surface 131 of the guide 13 in the deflected position of the lever element 12 shown in fig. 17 and 18, so that the lever element 12 engages in the guide 13. The lever element 12 is thus locked in the end position shown in fig. 17 and 18 relative to the guide 13, wherein the user can act on the lever element 12 and can separate the lever element 12 from the snap-in position by applying a sufficient force.

As fig. 13 and 14 show, the lever element 12 is also supported on the housing section 102 of the housing part 11 via the end section 124 on the leg 123.

The technical principle of the terminal device 1 of the embodiment shown in fig. 13 to 18 is similar to that of the embodiment shown in fig. 1 to 12. By means of the deflection of the lever element 12, the clamping foot 142 of the spring element 14 can be deflected from the clamping position (fig. 16) into the release position (fig. 18) in such a way that, when the lever element 12 is deflected, the actuating section 125 acts on the clamping foot 142 and moves this out of the region of the receiving space 17 inside the housing part 11, so that an electrical conductor can be inserted into the receiving space 17 through the socket 100 or the inserted conductor can be removed from the receiving space 17.

The basic idea of the invention is not limited to the embodiments described above but may also be implemented in different ways.

Terminal devices of the described type can be applied in completely different ways to connect electrical conductors to corresponding components. Such a terminal device can be used, for example, to form a distribution box, but can also be used in other electrical devices, such as, for example, a terminal block.
