SUMMARY OF THE INVENTION It is an object of the present invention to provide a terminal arrangement which can be easily and economically constructed in a compact design and which can be operated comfortably and reliably.

This object is achieved by the subject matter with the features of claim 1 .

Accordingly, the terminal device comprises a guide device arranged in the housing and provided with a guide surface extending along the pivot direction, the lever element being formed on the lever head and in a manner sliding on the guide surface of the guide device. a guided sliding guide so that when the lever element is pivoted along the pivoting direction between the first pivoted position and the second pivoted position, the sliding guide is on the guide surface; Moving.

In the case of terminal devices, the lever element is guided over the guide surface of the guide device through the lever head. The guide surface thus defines the movement path for the lever head, i.e. the pivoting movement of the lever element. When the lever element is adjusted, the lever head is slidably moved along the guide surface, whereby the lever element is pivoted to adjust the actuating part for adjusting the clamping wings of the spring element.

Since the lever element is guided using the guide surfaces of the guide device of the lever head, it is possible to make use of the bearing pin and eliminate the swivel bearing of the lever element. The movement path of the lever element is predetermined by the guide surface of the guide device, whereby the lever element is displaced when the lever head is pivoted and slidably guided. Since the lever element does not have to have a bearing pin mounted on the housing, the terminal device can be provided without a lever element protruding into a receiving space in which, for example, a conductor inserted into a plug-in opening is received. In addition, it can be configured in a small size.

For example, user actuation (no tools required) can be accomplished with a lever head. For example, the user can touch the lever head in order to adjust the lever element relative to the housing between the first pivoted position and the second pivoted position.

In one embodiment, the lever element can be pivoted relative to the housing about a pivot axis. The lever head is here arranged radially of the pivot axis on the outside of the actuating part and is thereby radially spaced from the actuating part. The lever head can be formed, for example, at the end of the lever element remote from the radially inner working portion.

In one embodiment, the guide surface on which the sliding guide portion of the lever head is guided is curved around the pivot axis. The guide surface thus predefines a movement path around the pivot axis along which the lever head slides with the aid of the sliding guide when the lever element is adjusted. Move by being guided.

For example, the lever head can be arranged on the side of the guide surface facing away from the actuating part. For example, the guide surface can be formed on the outer wall of the housing and can face outwards. For example, the lever head can be arranged outside the housing so that it can be easily and comfortably actuated by the user and moved to adjust the clamping wings of the spring element. It is possible to be forced to

In one embodiment, the lever element has an opening through which the guide device is engaged. For example, the opening may be bounded at one end by an actuating portion and at the other end by a lever head, for example two wings extending between the lever head and the actuating portion with an opening between the wings. part is formed. Here, for example, the guide device can be formed as a finger of the housing, the guide surface being formed, for example, on the side of the finger facing away from the actuating part, while, for example, the spring element supported with support wings on the side of the finger facing When the lever element is adjusted, the guide device moves into the opening so that the lever head slides along a guide surface formed in the guide device, so that the lever element is in a defined guide with respect to the housing. Moved in style.

In one embodiment, the sliding guide is formed by a step of the lever head. For example, the step can be formed at the transition between the wings of the lever element and the lever head, for example facing towards the (virtual) pivot axis about which the spring element pivots. It is possible.

In one embodiment, the lever head comprises two sliding guides, which extend parallel to each other, are spaced apart from each other along the pivot axis and are guided parallel to the guide surfaces of the guide device. be.

In one embodiment, the lever head comprises a stop for abutting against a stop surface of the guide device in the first pivoted position or the second pivoted position. The pivoting movement of the lever head is therefore limited through the stop, which in one pivot position abuts against the stop surface of the guide device, thereby making it impossible to pivot beyond a certain pivot position. Because it becomes The stop can be formed, for example, on a lever head radially outside the sliding guide, and the stop can be moved along the pivot axis relative to the sliding guide. be.

If the lever head comprises two sliding guides running parallel to each other, the stop can for example be formed between the sliding guides.

In one embodiment, the lever head includes a detent mechanism for latching engagement with a mating detent mechanism formed on the guide device in the first pivoted position or the second pivoted position. Accordingly, the lever element may be latched into the first pivoted position or the second pivoted position by the detent mechanism of the lever head engaged (by interlocking) with the mating detent mechanism of the guide device. is possible. Here, the latched connection can be opened by the user exerting a force on the lever head in excess of a predetermined releasing force, whereby the lever element is actually retained in a latched manner in a particular pivoted position. , the latch connection can be easily opened by the user to adjust the clamping wings of the lever element and thus the spring element.

In one embodiment, the actuating part of the lever element is received in a receiving pocket formed in the clamping wing. The actuating part thus acts on the clamping wings in a defined manner and moves in the receiving pocket when the lever element is adjusted. The receiving pocket can be formed, for example, by a curvature of the clamping wing, and at the position of the receiving pocket the clamping wing is bent through an angle of, for example, between 60° and 120°, for example about 90°. , the receiving pocket is engaged by the actuating part so that the actuating part can rotate in the receiving pocket when the lever element is pivoted.

In one embodiment, the lever element has an end remote from the lever head, which end is supported in the housing portion of the housing. The ends can be formed, for example, at the radially inner ends of the lever elements, and it is possible to form a support for the housing without the ends, but necessarily providing a swivel bearing.

In one embodiment, contact elements are provided on the housing, the contact elements, also referred to as current bars, being used to make contact with electrical conductors inserted into the plug-in openings. When an electrical conductor is inserted into the plug-in opening, the clamping wings of the spring element act on the electrical conductor in the clamping position, which clamps the electrical conductor together with the contact element so that the electrical conductor is inserted into the plug-in opening. to be mechanically locked in the part and additionally to make electrical contact with the contact element. For example, a potential distribution between different connections of the terminal arrangement can be provided through contact elements. The electrical terminal element is additionally or alternatively electrically connected to the contact element to produce a plug-in connection, whereby a conductor inserted into the plug-in opening is connected to the terminal element by contact with the contact element. can be electrically connected to the

In one embodiment, the contact element comprises a detent element latched with a spring element. The spring element may, for example, comprise a detent opening at the end of a support wing supported on the housing, in which the detent element of the contact element engages, thereby The contact element is connected to the spring element in latching fashion and interlockingly.

Additionally or alternatively, the contact element can be latched with the housing and for this purpose the contact element is latched with a detent device of the first housing part and the second housing part. block the latching connection of the contact element to the first housing part with a blocking part. The detent device of the first housing part can for example comprise one or more detent wings, the blocking part acting on the one or more detent wings, which means that the one or more detents This is to prevent deflection of the wings and thus release of the detent connection between the contact element and the housing.

The terminal device may comprise one or more plug-in openings and corresponding one or more spring elements and one or more lever elements, each plug-in opening preferably comprising a spring element and a lever. assigned to the element. If the terminal device comprises a plurality of plug-in openings and a corresponding plurality of spring and lever elements, this allows a plurality of electrical conductors to be connected to the terminal device, which for example This is to provide potential distribution through the terminal device.

A terminal device 1 in the form of a terminal block shown in FIGS. and these parts are connected together in a latching fashion to form a housing. Here, the plug-in openings 100 are formed on one housing part 10 on opposite sides of the housing, in order to bring the conductors 2 into electrical contact with the terminal device 1 . 2 allows it to be plugged into the opening along the plug-in direction E with the exposed conductor end 20 .

In the exemplary embodiment shown in FIGS. 1 to 12, three plug-in openings are formed on each of the opposite sides of the housing so that three electrical conductors 2 can be connected. , can be plugged into each side of the housing. A potential distribution can be defined with the terminal device 1 so that conductors 2 connected to the terminal device 1 can be placed at the same potential, for example ground potential, through the terminal device 1. is.

Each plug-in opening 100 is assigned a lever element 12, a guide device 13 and a spring element 14, which can be seen in FIGS. 1 and 2 compared to FIGS. The guide device 13 is formed in the form of a finger on the housing part 11 and contributes to the guidance of the correspondingly assigned lever element 12 . The spring element 14 can be actuated via the lever element 12 in order to adjust the spring element 14, in particular the clamping wings 142 of the spring element 14, between different positions, thereby opening the plug-in opening. A conductor inserted into 100 is mechanically locked into plug-in opening 100 and additionally electrically contacted or released from plug-in opening 100 again. This is further described hereafter.

The lever element 12, shown separately in FIG. 5, comprises a lever head 120 arranged outside the housing, as seen for example in FIGS. The lever head 120 is connected through two wings 123 to an actuation part 125 extending laterally between the two wings 123 , which actuation part is designed to act on the clamping wings 142 of the spring element 14 . 6 and 7, the working part is located in a receiving pocket 145 of the clamping wing 142 for this purpose.

The lever element 12 forms an opening 126 with which the lever element 12 rests against the assigned guide device 13 of the housing part 11, so that, for example, FIG. and as can be seen in FIG. 4 , the guide device 13 extends through the opening 126 in the form of a finger formed in the housing part 11 .

The lever head 120 is slidably guided on the guide device 13 , whereby the movement path along the adjustment direction V of the lever element 12 relative to the housing is predetermined through the guide device 13 . As can be seen in the separate view of the lever element 12 according to FIG. 5, the lever element 12 forms a stepped sliding guide 122 between the wings 123 and the lever head 120, the sliding The guide parts project inwardly from the wings 123 and are positioned to slide against assigned guide surfaces 131 on the guide device 13 . The guide surfaces 131 of the guide device 13, facing away from each other and curved about a pivot axis S, extend parallel to the edges of the guide device 13, about which the lever element 12 is located in the housing. can be swiveled against Therefore, the sliding guide portion 122 of the lever element 12 is also curved, so that the sliding guide portion 122 is in uniform contact with the guide surface 131 of the guide device 13, and when the lever element 12 pivots, the guide It slides on surface 131 .

The guide surface 131 cooperates with the sliding guide portion 122 of the lever head 120 to define the movement path of the lever element 12 along the turning direction V. As shown in FIG. When the lever element 12 is pivoted with respect to the housing, the lever head 120 moves along the adjustment direction V on the guide device 13 so that the sliding guide part 122 slides along the guide surface 131 and thereby Actuator 125 is aligned with clamp wing 142 to move clamp wing 142 within the housing.

The lever head 120 is spaced apart from the operating portion 125 in the radial direction of the pivot axis S. As shown in FIG. The guide surface 131 of the guide device 13 faces outwards and the lever head 120 is guided to slide on the outside of the housing whereby the user can press the lever head 120 to adjust the lever element 12 relative to the housing. 120 can be operated.

Working portions 125 are formed between wings 123 in the region of ends 124 . The lever element 12 is supported in the housing on each side on the housing part 102 by means of the ends 124, the ends 124 together with the guide device 13 being visible in particular in FIGS. , form the swivel bearing of the lever element 12 .

The stop 121 is formed between the sliding guides 122 of the lever head 120 and in the pivoted position of the lever element 12 shown in FIG. 13 against the stop surface 130 . The abutment of the stop 121 against the stop surface 130 is such that the lever element 12 cannot be pivoted beyond the pivoted position shown in FIG. means that it is impossible to

Each spring element 14 comprises a clamping wing 142 connected to a supporting wing 141 using a bend 140 . The curved portion 140 and the support wings 141 are supported on a support portion 132 of the guide device 13 , remote from the guide surface 131 and the stop surface 130 , so that the spring element 14 is attached to the housing part 11 forming the guide device 13 . is fixed against the finger of

The spring element 14 is held in contact with the support 132 through the assigned lever element 12 .

As can be seen in FIGS. 8 and 9, the contact element 16 in the form of a current bar with flat bar portions 160 and detent elements 161 (each assigned to a pair of spring elements 14) provides a return It is connected to the housing part 11 through a stop device 15 . The contact element 16 is interlockingly connected to the housing part 11 with a detent device 15 . The contact element 16 is engaged by means of respective detent elements 161 between the ends 143 formed on the spring element 14 (assigned to mutually opposite plug-in openings 100) and the return Adjacent the support wings 141 , the stop element engages in a detent opening 144 at the end 143 , whereby the contact element 16 is interlockingly connected to the spring element 14 .

In the assembled condition, the housing part 10 is connected to the housing part 11 in a latching fashion, and as seen in FIG. In order to engage the rib-shaped blocking portion 101 and thereby prevent deflection of the detent wings 150 and thus prevent release of the connection between the detent device 15 and the contact element 16, the housing part of the contact element 16 The latch connection to 11 is additionally locked.

The sequence in assembling the terminal device 1 can be explained with reference to FIGS. 6 to 10. FIG.

As can be seen in FIG. 6, the spring elements 14 assigned to the individual plug-in openings 100 are first placed against the housing part 11, so that each spring element 14 is connected to the supporting wings 141 and The curved portion 140 comes to rest against a support surface 132 formed on the rear side of the assigned guide device 13 .

The lever element 12 is then placed against the guide device 13 assigned to the plug-in opening 100 and moved into the position shown in FIG. 142 is fixed relative to the housing part 11 in a deflected state.

As shown in FIG. 8, the contact element 16 in the form of a current bar rests against the housing part 11 and the detent device 15 is in latching engagement with the contact element 16 and in addition the contact element 16 detent elements 161 become located between the ends 143 of adjacent spring elements 14 .

Lever element 12 can then be pivoted relative to housing part 11 into the position shown in FIG. Here, the clamping wings 142 of the spring element 14 follow the actuating portion 125 of the lever element 12 due to the elasticity of the spring element 14 and in each case come into contact with the assigned stop 162 of the contact element 16, which means defines the end position of the clamping wings 142 .

The housing is completed by mating the housing parts 10 as seen in FIG. 10, and when the housing parts 10 are mated, the block part 101 is detented as seen in FIG. A locking connection is established with the device 15 , whereby the connection between the contact element 16 and the housing part 11 is fixed. The terminal device 1 is thus ready for use and can be used for potential distribution in the connected conductors.

When the lever element 12 is in the non-actuated state in the assigned receiving space 17 of the housing, the clamping wings 142 of each spring element 14 project into the clamping position, which in the clamping position (FIG. 10) corresponds to the assigned This is because it acts on the conductor 2 inserted into the plug-in opening 100 which is closed. The clamping wings 142 can be pivoted out of the clamping position by actuating the lever element 12 so that the actuation part 125 acts on the clamping wings 142 to move the clamping wings 142 into the release position. In this position the receiving space 17 is released (see spring element 14 shown on the right side of FIG. 12). In the released position, the conductor 2 can be inserted into the assigned plug-in opening 100 with little force or a conductor inserted into the plug-in opening 100 . The body 2 can be removed from the plug-in opening 100 and thus released from the terminal device 1 .

When the lever 12 is pivoted, the actuating part 125 moves into the receiving pocket 145 formed in the clamping wing 142 , the actuating part 125 pivots in the receiving pocket 145 and the position of the actuating part 125 is adjusted by pivoting the lever element 12 . The clamp wings 142 are moved by changing .

During pivoting, the lever element 12 is additionally supported against the housing part 102 of the housing part 10 through the ends 124 on the wings 123, which can be seen in the transition from FIG. 10 to FIG. there is

In another exemplary embodiment shown in FIGS. 13 to 18, the lever element 12 is pivotably arranged on the housing part 11 and for this purpose a sliding guide inside the lever head 120. Through a lever head 120 with a portion 122 it is guided against a curved guide surface 131 of the guide device 13 formed on the housing part 11 . Furthermore, the lever element 12 can be swiveled relative to the housing part 11 between different swivel positions, which act on the clamping wings 142 of the spring element 14 and the clamping position (FIG. 16). To adjust the spring element between the release position (Fig. 18).

In the exemplary embodiment shown in FIGS. 13 to 18, the contact elements 16 are fixed to the housing part 11 and electrically connected to terminal elements 18 in the form of terminal pins. An electrical conductor can be inserted into the plug-in opening 100 of the housing part 11 in order to connect the electrical conductor to the terminal element 18 with the terminal device 1 .

In the illustrated exemplary embodiment, the lever element 12 comprises a (single) wing 123 connecting the lever head 120 to the actuation part 125 . The lever element 12 is therefore open on one side so that the wings 123 engage around the guide device 13 formed in the housing part 11 so that the lever head arranged outside the guide device 13 120 is connected to an actuating part 125 arranged in the guide device 13 .

The guide device 13 predefines a movement path for the pivoting of the lever element 12 along the pivoting direction V via a guide surface 131 formed therein. The guide surface 131 is curved for this purpose and thus extends around the (virtual) pivot axis of the lever element 12 .

A detent mechanism 127 is formed on the inner sliding guide portion 122 of the lever head 120 and, in the pivoted position of the lever element 12 shown in FIGS. A side detent mechanism 133 is engaged thereby latching the lever element 12 to the guide device 13 . The lever element 12 is thus locked against the guide device 13 in the end position shown in FIGS. 17 and 18 and the user can act on the lever element 12 by exerting a sufficient force to cause the lever element to move. 12 can be released from the detented position.

Lever element 12 is additionally supported on housing part 102 of housing part 11 with ends 124 on wings 123, which can be seen in FIGS.

The principle of operation of the terminal device 1 of the exemplary embodiment according to FIGS. 13-18 is similar to the exemplary embodiment according to FIGS. 1-12. By pivoting the lever element 12, the clamping wings 142 of the spring element 14 can be pivoted from the clamped position (Fig. 16) to the release position (Fig. 18), and when the lever element 12 is pivoted, the actuation The portion 125 acts on the clamping wings 142 to move the clamping wings out of the area of the receiving space 17 into the housing part 11 , so that the electrical conductor is inserted through the plug-in opening 100 into the receiving space 17 . or the inserted conductor can be removed from the receiving space 17 .

The concept forming the basis of the invention is not limited to the exemplary embodiments described above, but can also be implemented in other ways.

Terminal devices of the type described can be used in completely different ways, for connecting electrical conductors to assigned assemblies. Such a terminal arrangement may, for example, provide terminal blocks, but may also be used for other electrical equipment, such as for example series terminals.
