Description

Technical Field

[0001] This utility model relates to a wiring device having at least one terminal for connecting electrical wires. Background Technology

[0002] This wiring device includes at least one terminal block to which an electrical conductor can be inserted and connected, and a housing formed by at least one housing member. The terminal block has a contact element disposed on the housing, having a contact section for electrical contact with the electrical conductor, a spring element having clamping legs adjustable relative to the housing, and an operating element oscillatingly disposed on the housing. The clamping legs are configured to act on the electrical conductor in a clamped position to bring it into contact with the contact section. The operating element has an operating section for user operation and an operating section for acting on the clamping legs, and is adjustable from an unoperated position to an operating position to move the clamping legs to a release position, in which the clamping legs are moved away from the contact section compared to the clamped position.

[0003] The terminal block is implemented as a spring connector by using a spring element, wherein, in the connection position, the wire is clamped to the contact element by the elastic spring of the spring element and is thus electrically connected to the contact element.

[0004] In the terminal blocks known from DE 10 2019 127 464 B3, a spring element in the form of a tension spring is provided. This tension spring, through the action of an elastic spring, pulls the connected wire to abut against the corresponding contact element, thereby establishing a clamping connection between the wire and the contact element. For this purpose, the wire moves through an opening in the clamping leg during attachment and is clamped between the clamping leg and the contact element in the connected position.

[0005] The terminal block of DE 10 2019 127 464 B3 is equipped with a locking device that locks the clamping legs relative to the housing in the released position. When a wire is inserted, the locking device is triggered, releasing the lock and allowing the clamping legs to move out of the released position, thereby clamping the wire to the contact element. To move the clamping legs into the released position, especially to attach a wire, or to detach the connected wire from the terminal block, a tool, such as a screwdriver, can be attached to the terminal block, thereby applying force to the clamping legs.

[0006] In DE 10 2019 127 464 B3, the clamping legs are adjusted directly using a tool. However, in the terminal blocks known from DE 10 2019 135 203 A1 and DE 10 2020 104 140 A1, an operating element in the form of a pusher is provided. This pusher can be pressed into the housing of the terminal block to act on the clamping legs and move them to their released position. The operating element is pre-tensioned relative to the housing of the terminal block by a tension spring in the form of a pressure spring. In the terminal blocks known from DE 10 2019 135 203 A1, an operating nose is provided on the operating element, which hooks into the fixed section of the retaining element in the operating position of the operating element.

[0007] To connect the electrical wire to the terminals of the wiring device, the operating element can be moved to the operating position, thereby moving the clamping leg of the spring element to the release position. This releases space inside the wiring device housing, allowing the electrical wire to be inserted substantially weakly into the housing and thus connected to the terminals.

[0008] Therefore, the operation of the terminal blocks needs to be designed to be as intuitive as possible for the user. In particular, incorrect operation of the operating elements, which may lead to damage to the terminal blocks, should be avoided as much as possible. For example, such incorrect operation may occur when it is not clear to the user how to operate the operating elements that are oscillatingly arranged on the housing in order to connect the wires.

[0009] For example, a terminal block is known from DE 20 2019 105 075 U1 and DE 10 2019 131 141 A1, wherein the operating element is pivotally supported on the housing in the form of a lever. Utility Model Content

[0010] The objective of this invention is to provide a wiring device in which the operation of the terminal block's operating elements is simple and intuitive for the user.

[0011] This task is accomplished by having a wiring device with at least one terminal for connecting electrical wires.

[0012] Therefore, the housing has two edge segments that extend parallel to each other, forming a receiving opening between them, into which the operating segment of the operating element is placed in the operating position in the operating opening.

[0013] The operating element is pivotally supported on the housing and has an operating section for user operation and an actuating section for acting on the clamping legs. The operating section is accessible from the outside of the housing, for example, by the user using a tool such as a screwdriver, or alternatively by hand; however, the actuating section is operatively connected to the clamping legs of the spring element. Therefore, by adjusting the operating element, an adjusting force is applied to the clamping legs through the actuating section, such that when the operating element is adjusted from the unoperated position to the operating position, the clamping legs are actuated and move towards the release position.

[0014] To move the clamping leg of the spring element to the released position, the operating element can move from the unoperated position to the operating position, and for this purpose, it can pivot on the housing of the wiring device. In the unoperated position, the operating element protrudes outward relative to the housing, while in the operating position, the operating element is positioned within a receiving opening in the housing, which is constructed between parallel edge segments of the housing. Thus, in the operating position, the edge segments at least partially enclose the operating segment of the operating element, such that the operating segment is close to and recessed into the housing.

[0015] In the operating position of the operating element, the clamping leg of the spring element is in the released position. In the released position, the clamping leg is held relative to the housing in such a way that the clamping leg is directly or indirectly engaged with the housing or a component disposed on the housing. For example, the operating element may be engaged relative to the housing in the operating position such that, when the operating element is in the operating position, the clamping leg is indirectly held in the released position by means of the operating element.

[0016] Wiring devices, for example, can be supplied to customers by the manufacturer with the operating element in the operating position.

[0017] The operating section can preferably be enclosed within the receiving opening in the operating position so that the user cannot easily remove the operating section from the operating position. For example, the terminal block can be designed such that when the user plugs a wire into the terminal block housing, the terminal block is automatically triggered, causing the operating element to be released from the operating position and the clamping legs to be released from the released position so as to clamp the wire and make electrical contact between the wire and the contact element of the terminal block.

[0018] Therefore, users can operate the terminal blocks simply and intuitively. Wiring is performed by the user inserting the wire into the terminal block, which automatically triggers the terminal block and releases the operating element from its operating position. Because the operating element is recessed into the receiving opening with its operating section in the operating position, and therefore the operating section does not protrude from the housing, the user cannot manually remove the operating element from its operating position. Thus, the user cannot, or at least can only with difficulty, misoperate the operating element to remove it from its operating position, and can intuitively see that wiring is required by inserting the wire, without having to manually operate the operating element.

[0019] In one design, at least one of the edge segments has a defining edge that, when viewed in the operating position of the operating element along a direction perpendicular to the swing plane, is arranged parallel to the outer surface of the operating segment. The operating element is capable of swinging along the swing plane. In a side view perpendicular to the swing plane, the edge of the edge segment and the outer surface are oriented parallel to each other. Preferably, when the operating element is in the operating position, the outer surface is at least approximately flush with the edge. Due to the parallel extension of the outer surface relative to the edge, the operating element does not protrude outward relative to the edge segment, or only slightly. Therefore, the operating element cannot or is difficult to operate by the user, wherein the terminal is preferably automatically triggered when the electrical wire is plugged into the housing and thus connected to the terminal block.

[0020] Preferably, when the operating element is in the operating position, the edges of the edge segment defining the receiving opening extend parallel to the outer surface of the operating segment.

[0021] In one design, the operating section has an inner surface pointing inwards from the housing. This inner surface may, for example, extend parallel to the outer surface. For instance, the operating section may be configured with a head that a user can manually or with the aid of a tool apply to operate the operating element, wherein the head of the operating element is defined by an outwardly pointing outer surface and a opposing inwardly pointing inner surface, and protrudes relative to the swing axis of the operating element in a lever-like manner.

[0022] Preferably, the inner surface is accessible from the outside of the housing in the inactive position of the operating element. Conversely, the inner surface is not accessible from the outside of the housing in the operating position of the operating element. Therefore, in the operating position, the operating element is recessed into the receiving opening such that the user cannot, for example, use a tool to grasp the operating section from below to remove it from the operating position. Thus, it is impossible, or at least difficult, to apply torque to the operating element by grasping the operating section to move it from the operating position to the inactive position.

[0023] In one design, the operating element has at least one protrusion formed on an operating section, which, in the operating position of the operating element, engages with a notch on at least one edge section. The protrusion may, for example, project from the operating section along an arrangement direction in which the edge sections of the housing are spaced apart from each other. This protrusion, particularly in the area where a tool engagement is formed on the operating section, can, for example, create an extension of the operating section.

[0024] In one design, the operating section has a tool engagement for attaching a tool. This tool engagement can be formed, for example, by a slotted slit into which a tool, such as a screwdriver, can be inserted to act on the operating element, particularly for transfer to the operating position.

[0025] In one design, the operating section preferably has at least one outwardly pointing rib on its outer surface. This rib, for example, can provide a gripping surface for the user, allowing the user to apply pressure to the outer surface of the operating section with their fingers, and the rib structure at least makes slippage more difficult.

[0026] In one design, the spring element is constructed as a tension spring. In this case, the clamping legs of the spring element are configured to pull the electrical wire into contact with the contact element by the spring force. In this case, an opening may be formed in the clamping legs, through which the electrical wire can pass when plugged into the terminal block, so that after the clamping legs are triggered from the release position, the electrical wire is pulled into clamping contact with the contact element.

[0027] Alternatively, the spring element can be configured as a compression spring. In this case, the clamping legs are configured to press the electrical wire against the contact element by the spring force. When plugged into the terminal block, the electrical wire reaches the space between the clamping legs and the contact element, wherein, after the clamping legs are triggered from the release position, the clamping legs act on the electrical wire and press it against the contact element.

[0028] The spring element may, for example, have a support leg by which it is supported on the housing and held in a position on the housing. The clamping leg can be elastically deflected relative to the support leg, wherein the clamping leg is deflected in the release position such that the spring element is elastically tensioned, and the clamping leg moves out of the release position in an elastically preloaded manner after being released from the release position.

[0029] In one design, the spring element's support leg is supported between two adjacent housing parts. Therefore, the support leg rests on the housing, and for this purpose, abuts against, for example, a support section on the wall of one housing part, and additionally, for example, against a support section on the wall of an adjacent housing part. Thus, the support leg is jointly supported by the two housing parts of the adjacent terminal block.

[0030] In at least one terminal block, a conductor is electrically contacted with an electrical contact element in such a way that, when the conductor is plugged into the terminal block, clamping legs act on the conductor, causing the conductor to be spring-loaded elastically in the direction of contact with the contact element. To facilitate the insertion of the conductor, the clamping legs of the spring element can be elastically deflected, for example, by means of a tool or by operation of an actuating element, so as to move the clamping legs to a release position in which space in the area of ​​the plug opening is released, and the conductor can then be inserted into the plug opening substantially without force, or the connected conductor can be easily removed from the terminal block.

[0031] In one design, if the clamping leg moves to the release position, the clamping leg is held relative to the housing in the release position. This can be achieved by direct locking of the clamping leg relative to the housing, or by indirect locking, for example, via an operating element.

[0032] In one design, at least one terminal block has a trigger element configured to, in conjunction with a wire inserted into the terminal block, release a clamping leg from a release position. The trigger element actuates the clamping leg from the release position so that, upon wire insertion, the clamping leg is automatically released from the release position and then transferred to a clamping position in which the wire inserted into the terminal block makes electrical contact with the terminal block's contact element. Because the trigger element deflects upon wire insertion, the terminal block automatically closes upon wire insertion. This simplifies the connection process and ensures reliable contact between the wire and the contact element.

[0033] Such terminals can be provided by the manufacturer, for example, with the clamping legs in the released position, in which the clamping legs of the spring element are held in the released position relative to the housing and can be automatically triggered by a triggering element when an electrical wire is inserted.

[0034] In one design, the trigger element has a trigger leg configured to interact with the electrical wire when it is plugged into the terminal block. Through this interaction, the trigger leg is actuated, causing the clamping leg to release from a release position. A housing defines a receiving space into which the electrical wire can be introduced by insertion into a mating opening. The trigger leg extends within the receiving space to interact with the electrical wire. Specifically, the electrical wire can be inserted into the mating opening along the mating direction, wherein the trigger leg extends at least at its end section (approximately) transversely to the mating direction within the receiving space.

[0035] The triggering element can be constructed as a single, self-rebounding element.

[0036] In one design, the trigger element has a support end, and the trigger leg can be elastically adjusted relative to the support end by acting in conjunction with a wire plugged into a terminal block. The trigger element is supported on the housing via the support end, for example, by fixing the support end to at least one housing member and its associated connecting device. Thus, the trigger element is fixed to the housing via the support end in such a way that the support end is operatively connected to the connecting device and thereby held against torque on the housing.

[0037] In one design, the supporting end of the trigger element is supported between two adjacent housing members. For this purpose, the supporting end engages, for example, in a engagement opening in the wall of one housing member, and additionally supports the housing member of the adjacent terminal, also engaging, for example, in a engagement opening in the wall of the adjacent housing member. Thus, the supporting end is jointly supported by the two housing members of the adjacent terminal.

[0038] In one design, the operating element is locked with the trigger element in the operating position. Therefore, in the operating position, the operating element is held in place by the trigger element, such that the clamping leg of the spring element is also held in its released position, in which a wire can be easily attached to a terminal block, or the connected wire can be removed from the terminal block in a substantially effortless manner. After the locking is released, the operating element can preferably be automatically adjusted back towards the non-operated position under spring preload. Here, for example, spring preload on the operating element can be caused by the clamping leg, which elastically deflects in the operating position, and after the operating element is released, the spring mechanically acts on the operating element to transfer the operating element from the operating position towards the non-operated position.

[0039] In one design, the operating element has a locking section for engaging with a locking device of the trigger element in the operating position. The locking section can, for example, be arranged on the side of the operating element opposite to the operating section (with respect to a pivot axis that allows the operating element to be pivotally supported on the housing), preferably approximately exactly opposite to the operating section with respect to the pivot axis. The operating element is held in the operating position by engaging with the locking device of the trigger element via the locking section, thereby maintaining the operating element in the operating position. However, it can be released from the operating position simply and reliably upon insertion of an electrical wire by triggering the trigger leg.

[0040] The locking device of the trigger element can be configured, for example, by an opening, such as by a protrusion, into which a locking section of the operating element engages in the operating position of the operating element. Thus, through the form-fitting engagement of the locking section in the opening of the trigger element, the operating element is held in its operating position, wherein engagement can be cancelled by adjusting the trigger leg, and thus the operating element can be released from the operating position used to move the clamping leg to the release position.

[0041] In one design, the operating element is pivotally supported between two adjacent housing members. Thus, the adjacent housing members jointly support the operating element between them. For example, each housing member can have a shaft end that engages in a support opening on the operating element, thereby providing pivotal support for the operating element between the housing members.

[0042] In one design, the housing has multiple housing components arranged sequentially along an arrangement direction. These housing components can be disposed on multiple terminals, such that the wiring device is constructed by multiple terminals arranged sequentially along the arrangement direction.

[0043] Edge segments are preferably formed on the walls of adjacent housing members, and these edge segments form receiving openings therebetween for accommodating and recessing the operating segment in the operating position of the operating element. The housing members are attached to each other along the arrangement direction. Here, each receiving opening is formed between an edge segment on a housing member and an adjacent housing member.

[0044] Preferably, the wiring device has a housing into which housing components arranged sequentially along an arrangement direction can be introduced along an assembly direction. The housing has a first guiding device having at least one first guiding tab. The sequentially arranged housing components have a second guiding device having at least one second guiding tab. When the sequentially arranged housing components are introduced into the housing along the assembly direction, at least one second guiding tab of the second guiding device is guided at at least one first guiding tab of the first guiding device.

[0045] The wiring device is completed by attaching the housing components of the terminals to each other along the arrangement direction. The housing components can be introduced into the housing of the wiring device in a sequential arrangement, so that in the assembled state, the housing components are accommodated in the housing and thus enclosed by the housing.

[0046] The housing may, for example, have a box shape, open on one side, allowing successively arranged housing components to be pushed into the box-shaped housing. In another design, the housing may, for example, have a frame shape open on both sides, into which successively arranged housing components can be pushed.

[0047] Here, the housing has a first guiding device for guiding the successively arranged housing members, and for this purpose works in conjunction with a second guiding device for the successively arranged housing members. Each guiding device has at least one guiding tab, wherein, when the successively arranged housing members are pushed into the housing, these guiding tabs guide each other such that the successively arranged housing members engage with the housing in a guided manner.

[0048] The advantages of a housing, a disc-shaped terminal block structure, and a so-called monolithic design are combined with each other.

[0049] Because the terminal blocks are constructed with individual housing components that can be attached to each other along the arrangement direction to complete the wiring device, the housing components can be designed so that the terminal block parts, such as spring elements and contact elements, can be easily assembled onto the respective housing components. Each terminal block's housing component is not, for example, closed relative to the outside; rather, the terminal block's housing is only complete after the terminal block's housing components are attached to each other. This facilitates the assembly of the individual terminal blocks and allows for various combinations with other terminal blocks.

[0050] Since the sequentially arranged terminals are embedded into the housing in an assembled state, a mechanically stable device is also achieved, wherein the housing components of the terminals are housed in the housing in a defined manner in a sequentially arranged state and fixed to the housing. By means of a guiding device, the housing components are introduced into the housing in a defined manner and supported on the housing in an assembled state, thereby completing an integrated, mechanically stable wiring device.

[0051] In one design, at least one housing component has at least one second guide tab, which is guided at the first guide tab of the first guiding device. Advantageously, each housing component has at least one second guide tab, which is guided at the first guide tab of the first guiding device. Thus, one (or all) of the housing components is guided on the outer casing.

[0052] In one design, at least one, preferably each, of the housing members has a wall extending along a plane perpendicular to the arrangement direction, and at least one second guide tab protrudes from this wall along the arrangement direction. The housing member of each terminal may be disc-shaped, wherein the wall of the housing member extends perpendicular to the arrangement direction and has a dimension in a plane perpendicular to the arrangement direction that is significantly larger than the width of the terminal (measured along the arrangement direction). Here, the guide tab disposed on the housing member protrudes from the wall along the arrangement direction and is therefore laterally constructed on the wall.

[0053] Preferably, two second guide tabs are formed on at least one, or more, of the housing components of the terminal block, and these second guide tabs are arranged on opposite sides of the wall. These guide tabs project from the wall along the arrangement direction, but point in different, opposite directions. When the successively arranged housing components are pushed into the housing, each guide tab is guided by its corresponding guide tab on the first guiding device of the housing, thus providing reliable guidance while achieving mechanical stability support in the assembled state.

[0054] The guide tabs may be formed on the upper edge of the wall, pointing in the assembly direction, and / or on the lower edge of the wall, pointing in the assembly direction, parallel to the wall, and protrude from the wall on one or both sides. Each guide tab of the housing component is guided on the corresponding guide tab on the housing.

[0055] In one design, at least one first guide tab and / or at least one second guide tab constitute a dovetail-shaped guide. If, for example, two second guide tabs are formed on the wall of a terminal housing member, protruding from the wall along an alignment direction and pointing in different directions, these guide tabs can collectively form a trapezoidal shape in cross-section, providing the dovetail-shaped guide. Similarly, for example, two first guide tabs are formed on the wall of a housing, collectively forming a trapezoidal shape, with the second guide tabs of the corresponding housing member engaging with this trapezoidal shape, thereby providing guidance when the housing member is pushed into the housing, and in the assembled state, the assembly of the housing member is mechanically and stably supported at the housing.

[0056] The arrangement direction and the assembly direction are preferably perpendicular to each other. The (disc-shaped) terminals are attached to each other along the arrangement direction, in such a way that the housing components are arranged sequentially along the arrangement direction. The housing components are pushed into the housing in a sequentially arranged state along an assembly direction perpendicular to the arrangement direction, so that the housing components are enclosed in the housing in the assembled state.

[0057] Here, at least one first guide tab and at least one second guide tab advantageously have side recesses with respect to a vertical direction perpendicular to the assembly direction and the alignment direction, such that at least one first guide tab and at least one second guide tab support each other along the vertical direction. These guide tabs protrude relative to a plane unfolded by the vertical direction and the assembly direction, such that these guide tabs hook and engage with each other. These guide tabs here form side recesses with respect to the vertical direction by a retraction along the alignment direction, such that the guide tabs engage and support each other in a plane unfolded by the alignment direction and the vertical direction. These guide tabs are movable relative to each other along the assembly direction, but form-fittingly support each other in a plane perpendicular to the assembly direction.

[0078] Figure 16 An enlarged side view of the operating element in the operating position is shown. Detailed Implementation

[0079] Figures 1 to 4 An embodiment of the wiring device 3 is shown, which has a plurality of terminals 1, 1A, and 1B, which are collectively enclosed in a housing 30. The terminals 1, 1A, and 1B are arranged sequentially along an arrangement direction A and are collectively enclosed in the housing 30. Each terminal 1, 1A, and 1B is provided with a insertion opening 100 on a housing member 10, 10A, or 10B respectively. A conductor 2 can be inserted into the insertion opening along the insertion direction E with its conductor end 20 (with insulation stripped) to connect the conductor 2 to the terminal 1, 1A, or 1B.

[0080] Figure 5 An embodiment of terminal 1 is shown in cross-sectional view. The terminal has a housing 10 with a mating opening 100 formed therein for inserting an electrical wire 2 along the mating direction E. Other terminals 1A and 1B may be structurally and functionally identical to terminal 1, such that the following description applies to all terminals 1, 1A, and 1B.

[0081] However, it can also be considered that terminals 1, 1A, and 1B differ in their operating principles and, in particular, do not possess all the components described below.

[0082] The housing 10 defines a receiving space 101 into which the conductor 2, with its insulation stripped, is introduced when it is inserted into the insertion opening 100 along the insertion direction E. In the connected position, the conductor 2, with its insulation stripped, is located inside the receiving space 101 and is electrically connected to the terminal block 1 via the clamping leg 120 of the spring element 12, which is in the form of a current bar contact element 11.

[0083] The spring element 12 has a support leg 121 that rests on the wall 106 of the housing 10. The clamping leg 120 is elastically deflectable relative to the support leg 121, and in particular, deflected in such a way that the clamping leg 120 clamps the wire 2 connected to the terminal 1 in the clamped position, and under elastic preload, pushes the wire into contact with the contact element 11, thereby making the wire 2 electrically contact the contact element 11 through its conductor end 20.

[0084] The contact element 11 has a contact section 110 that extends planarly within the housing 10. When the wire 2 is connected to the terminal 1, the wire 2, with its conductor end 20, is pressed against the contact section by the spring preload of the clamping leg 120. A contact device 111, arranged in the plug connector section 15, is connected to the contact section 110, through which the terminal 1 can be plugged into the ground of the provided electrical pairing plug connector.

[0085] In the illustrated embodiment, the operating element 14 is pivotally supported on the housing 10 of the terminal block 1 via a pivot shaft 140. The operating element 14 is pivotable relative to the housing 10 about the pivot shaft 140, wherein the operating section 141 is accessible from outside the housing 10 and can be operated by a user, for example, while using a tool.

[0086] In the illustrated embodiment, the swing shaft 140 is formed on the housing 10 disposed on the terminal 1, and the shaft end 140' of the housing 10A adjacent to the terminal 1A is engaged into the housing 10, thus completing the swing support of the operating element 14 on the housing 10, as this is achieved from Figure 6A , 6B As can be seen from the text.

[0087] The operating element 14 is operatively connected to the clamping leg 120 of the spring element 12. For this purpose, the spring element 12 extends through a through opening 142 inside the operating element 14 such that the spring element 12 surrounds the swing shaft 140 with a curved intermediate section 122, as this... Figure 5 As can be seen, the support leg 121 extends from the opening 142 on the first side and is supported at the housing member 10. In contrast, the clamping leg 120 extends from the operating element 14 on the opposite second side and extends within the receiving space 101 in the region of the insertion opening 100 such that the spring element 12 can act through the clamping leg 120 on the electrical wire 2 inserted into the insertion opening 100, so that the electrical wire contacts the contact element 11 and is further mechanically locked.

[0088] Terminal 1 has a trigger element 13, which is fixed to housing 10 by a support end 132 and is thus supported relative to housing 10 against torque. A trigger leg 130 extends from the support end 132 and extends substantially transversely to the insertion direction E into receiving space 101, and further extends in a region aligned with insertion opening 100.

[0089] According to Figures 7A-7C A separate view of the trigger element 13, according to Figure 8A , 8B Detailed drawings of the housing parts 10 and 10A of the terminal blocks 1 and 1A, and according to Figure 9 As can be seen in the cross-sectional view, the support end 132 of the trigger element 13 is connected to the connecting devices 103, 103' of the adjacent housing parts 10, 10A in a form-fit manner. The support end 132 of the trigger element 13, which is composed of a strip spring element, has notches 134, 135 on its opposing side edges, which engage with the protruding elements 104, 104' on the connecting devices 103, 103' in the assembled state.

[0090] Connecting devices 103 and 103' are respectively configured through engagement openings 107 and 107', into which a support end 132 engages, such that the support end 132 is form-fitted into the housing member 10. Here, the form fit between the support end 132 and the housing member 10 is such that the support end 132 cannot slide out of the connecting devices 103 and 103', and furthermore, the support end 132 is supported on the housing member 10 in such a way that when the trigger leg 130 elastically deflects, the torque on the support end 132 can be absorbed and discharged into the housing member 10, and the support end 132 is thus held in position relative to the housing member 10.

[0091] The engagement openings 107, 107' are formed on the wall sections 106, 106' of the respective housing parts 10, 10A, the wall sections protruding from the planar sidewalls 105 of the housing parts 10, 10A, as if from... Figure 6A , 6B As can be seen from the text.

[0092] As this is based on Figure 9 As can be seen in the cross-sectional view, the support end 132 of the terminal 1 is accommodated between the housing parts 10, 10A of the adjacent terminals 1, 1A, such that the support end 132 is held in a form-fitting manner on the mutually mirror-reversed connecting devices 103, 103' of the housing parts 10, 10A of the terminals 1, 1A.

[0093] The trigger leg 130 is used in conjunction with the electrical wire 2 inserted into the plug opening 100, in particular to enable the electrical wire 2 to be automatically connected to the terminal 1 when the clamping leg 120 is triggered.

[0094] The trigger element 13 has an opening 131, which is used when the operating element 14 has been transferred along the operating direction B. Figure 5 In the operating position shown, the operating element 14 engages with the opening via a protruding locking section 143. In the operating position, the operating element 14 engages with the opening 131 via the locking section 143 and is further locked onto the trigger leg 130, thereby locking the operating element 14 in the operating position.

[0095] In the illustrated embodiment, the trigger leg 130 is self-bent. An intermediate section 136 extends between the free end 138 of the trigger leg 130, which is opposite to the support end 132, and the leg section 137 of the trigger leg 130, which is aligned with the support end 132 and has an opening 131. This intermediate section extends laterally between the free end 138 of the trigger leg 130 and the leg section 137 of the trigger leg 130 that carries the opening 131. By giving the trigger element 13 an appropriate shape, the trigger element 13 can be matched to a given structural space condition within the receiving space 101 of the housing 10.

[0096] If the operating element 14 is operated along the operating direction B, and thereby pivots relative to the housing member 10 about the swing axis 140, according to Figure 5In the operating position, the operating element 14 drives the clamping leg 120 of the spring element 12 through the actuating section 144, thereby adjusting the clamping leg 120 to the release position. In the release position, the clamping leg 120 moves away from the contact section 110 of the contact element 11 with its free end, thereby releasing the area inside the receiving space 101 that is aligned with the plug-in opening 100 along the plugging direction E, so that the wire 2 can be inserted into the plug-in opening 100 without being obstructed by the clamping leg 120, and can then be connected to the terminal 1 in a substantially unobstructed manner.

[0097] When the operating element 14 is in the operating position, and consequently the clamping leg 120 is in the released position, the conductor 2 with its stripped conductor end 20 is inserted into the insertion opening 100 and thus introduced into the receiving space 101 along the insertion direction E. The conductor 2 then abuts against the end section 138 of the trigger leg 130 of the trigger element 13, causing the trigger leg to elastically deflect relative to the support end 132, and consequently, relative to the housing 10. As a result, the trigger leg 130 is adjusted along the insertion direction E relative to the locking section 143 of the operating element 14, causing the locking section 143 to disengage from the opening 131, thereby releasing the operating element 14 from the operating position.

[0098] On the side of the opening 131 facing the free end 138 of the trigger leg 130, there is a sliding element 133, which is constructed by a curved section of the trigger element 13 formed as a plate element. In the locked position, the locking section 143 abuts against the sliding element, and when released from the lock, the locking section 143 slides on the sliding element.

[0099] Because the conductor 2 acts on the trigger leg 130 with a lever arm that is larger than the lever arm acting on the locking section 143, the trigger leg 130 can be deflected by a smaller force applied by the conductor 2, thereby easily and reliably releasing the lock when the conductor 2 is inserted.

[0100] As from Figure 5 Combination Figure 7B As can be seen, the sliding element 133 bends relative to the leg section 137 of the trigger leg 130 in a certain direction, which points away from the operating element 14 along the insertion direction E. Here, in the locking position where the locking section 143 engages in the opening 131, the locking section 143 is located at the support point C on the sliding element 133, which is offset relative to the plane P, and the leg section 137, aligned with the support end 132, extends along the plane P. Thus, when the operating element 14 engages with the trigger element 13 through the engagement of the locking section 143 in the opening 131 on the leg section 137, the operating element 14 applies torque to the trigger element 13 through the locking section 143, the torque being determined according to... Figure 5 In the cross-sectional view, it points counterclockwise, and further along the direction that further strengthens the locking engagement between the locking section 143 and the opening 131.

[0101] During engagement, the locking segment 143 slides into the opening 131 upon elastic deflection of the trigger leg 130, and then the trigger leg 130 returns to its initial position, in which the trigger leg 130 engages with the locking segment 143 of the operating element 14. The trigger leg 130 is then loaded on the sliding element 133 by the locking segment 143 of the operating element 14, and the resulting torque is pressed towards the operating element 14, causing the locking segment 143 to move until it is fully engaged with the opening 131 on the support leg segment 137.

[0102] After the locking mechanism is released when the electrical wire 2 is inserted, the operating element 14 is disengaged from the operating position due to the elastic preload on the clamping leg 120 and resets in the opposite direction of operation B. Here, the clamping leg 120 clamps against the electrical wire 2, thereby pushing the conductor end 20 into contact with the contact element 11, so that the wire 2 is electrically connected to the terminal 1 and is also mechanically locked.

[0103] If it is necessary to loosen the wire 2 from the connection position and remove it from the terminal 1 again, the operating element 14 can be moved back to the operating position, causing the clamping leg 120 to disengage from the wire 2. Thus, the wire 2 can be removed from the terminal 1 in a substantially effortless manner.

[0104] In the illustrated embodiment, each terminal block 1, 1A, 1B is equipped with a housing 10, 10A, 10B.

[0105] Housing components 10 and 10A are respectively as follows: Figure 6A , 6B Housing components 10, 10A and according to Figure 14A , 14B The housing components 10 and 10A are constructed as described in the case of housing component 10 of 14C. Each of these housing components 10 and 10A has a central wall 105, a raised wall section 106 protruding from the central wall on a first side, the wall section 106 being configured with a mating opening 107 and a connecting device 103, and a raised wall section 106' protruding from the central wall on a opposite second side, the wall section 106' being configured with a mating opening 107' and a connecting device 103'. Thus, the housing components 10 and 10A on the first side are used to receive, support, and bear the components of the terminals 1, 1A, and 1B disposed on the housing components 10 and 10A, and have a insertion opening 100 on the first side for inserting the electrical wire 2. In contrast, the housing components 10 and 10A on the second side of the rear side are used to complete the housing of adjacent terminals 1, 1A, and 1B.

[0106] According to Figure 10 As can be seen in the cross-sectional view, housing members 10 and 10A are housed in the middle of the outer casing 30 of the wiring device 3. The outer housing members 10B and 10C each have a central wall 105, but here only one side bears the wall section 106 or 106'. Therefore, housing member 10B is attached to housing member 10 and has only one wall section 106, while the back side does not have a wall section 106'. In contrast, housing member 10C is attached to housing member 10A, and thus the housing for use with terminal 1A is complete, and for this purpose only has one wall section 106', without the wall section 106, as can be seen from this. Figure 10 As can be seen from the text.

[0107] In the illustrated embodiment, the housing parts 10, 10A, and 10B of terminals 1, 1A, and 1B are attached to each other along the arrangement direction A, as shown in... Figure 6A and Figure 6B As illustrated by means of housing parts 10 and 10A. The housing parts 10, 10A and 10B of terminals 1, 1A and 1B are completed here by the housing parts 10, 10A and 10B of adjacent terminals, so that the housing parts 10, 10A and 10B together constitute the housing for terminals 1, 1A and 1B.

[0108] For assembling the wiring device 3, housing parts 10, 10A, and 10B are pushed into the housing 3 in a sequential arrangement along the assembly direction M, so as to enclose the wiring terminals 1, 1A, and 1B within the housing 30, as if from this... Figure 1 and Figure 3 As can be seen from the text.

[0109] Housing components 10, 10A, 10B, and 10C each have a guiding device 16, which has guiding tabs 160, 160', 161, and 161'. These guiding tabs are guided on the guiding devices 31 of the housing 3 and on the guiding tabs 310, 310', 311, and 311' provided therewith, as if from... Figure 10 As can be seen from the image. The guiding devices 16 and 31 implement dovetail-shaped guiding portions, which allow the housing parts 10, 10A, 10B, and 10C to be pushed into the outer shell 30 in a guided manner when they are attached to each other.

[0110] As this comes from Figure 10 Combination Figure 6A , 6B as well as Figures 14A-14CAs can be seen, the two intermediate housing parts 10, 10A each have two guide tabs 160, 160' on the upper edge of the wall 105, and two guide tabs 161, 161' on the lower edge of the wall 105. These guide tabs protrude from both sides of the wall 105 and together form a trapezoidal shape. The upper and lower guide tab pairs 160, 160' or 161, 161' thus configured can be pushed between the guide tab pairs 310, 310' or 311, 311' disposed on the top wall 300 or bottom wall 301 of the outer casing 30, so as to engage the housing parts 10, 10A, 10B, 10C with the outer casing 30.

[0111] As this comes from Figure 10 As can be seen, the two outer housing parts 10B and 10C each have guide tabs 160, 160', 161, and 161' on only one side of the wall 105 (facing inwards and inside), which work together with the guide tabs 310, 310', 311, and 311' of the guide device 31 of the housing 30.

[0112] The sequentially arranged housing components 10, 10A, 10B, and 10C are introduced in a guided manner. This is achieved by fitting trapezoidal guide tabs 160, 160', 161, and 161' onto guide tabs 310, 310', 311, and 311' on the outer shell 30, whose cross-sections are complementary to those of the guide tabs. Figure 10 As can be seen from the text.

[0113] These guide tabs are respectively constructed with side recesses about the vertical direction V perpendicular to the assembly direction M and the arrangement direction A, so that housing parts 10, 10A, 10B, and 10C are configured according to... Figure 10 In the cross-section corresponding to the plane perpendicular to the assembly direction M, it is supported in all spatial directions in a shape-fitting manner with respect to the housing 30, but is movably guided on the housing 30 along the assembly direction M.

[0114] By providing the housing 30, the advantages of the disc-shaped modular construction of each terminal block 1, 1A, 1B and the self-enclosed wiring block (also called a single block) are combined. Therefore, housing parts 10, 10A, 10B, and 10C can each be constructed with one side open, and thus the components of terminal blocks 1, 1A, and 1B can be easily attached and assembled. The housing for terminal blocks 1, 1A, and 1B is completed by attaching housing parts 10, 10A, 10B, and 10C. After inserting the successively arranged housing parts 10, 10A, 10B, and 10C into the housing 30, an integrated, mechanically stable wiring device 3 is completed, wherein housing parts 10, 10A, 10B, and 10C are mechanically fixedly housed in the housing 30 and connected.

[0115] An axial fixing device 17 is formed on the wall 105 of the intermediate housing parts 10 and 10A, wherein locking noses 170 and 171 protrude from the wall 105 on the upper and lower edges, respectively. In the assembled state, as according to Figure 11 As shown in the cross-sectional view, the locking noses 170 and 171 engage with the locking openings provided on the top wall 300 and bottom wall 301 of the housing 30.

[0116] The outer housing parts 10B and 10C, for example, have an upper locking nose 170 for engaging with a locking opening provided on the top wall 300 of the housing 30, but do not have a lower locking nose 171.

[0117] Figure 12 and Figures 13A-13C A separate view of the housing 30 is shown. It can be seen that the guide device 31 has a dovetail arrangement of tabs 310, 310', 311, 311' on the top wall 300 and bottom wall 301 of the housing 30.

[0118] On the walls 105 of housing parts 10, 10A, and 10C, locking elements 108' in the form of spring tongues are formed on the respective second sides. When housing parts 10, 10A, 10B, and 10C are attached, these locking elements engage with the corresponding locking openings 108 on adjacent housing parts 10, 10A, and 10B, so that housing parts 10, 10A, 10B, and 10C are pre-assembled and locked together along the arrangement direction A during attachment. After the pre-assembled components are inserted into the housing 30, the wiring device 3 is assembled and mechanically stabilized by the enclosure of the housing 30.

[0119] In the illustrated embodiment, each terminal block 1, 1A, 1B is provided with a plug connector section 15 formed on the housing 30, and the contact device 111 of the contact element 11 is inserted therein.

[0120] In wiring device 3, according to Figure 3 and Figure 4 In the operating position, the operating sections 141 of the operating elements 14 of terminals 1, 1A, and 1B are respectively accommodated in the corresponding accommodating openings 102 of terminals 1, 1A, and 1B. The accommodating openings 102 are formed between the edge sections 109 on the walls 105 of the housing parts 10, 10A, 10B, and 10C arranged successively along the arrangement direction A.

[0121] As this is based on Figure 15 and Figure 16As can be seen in the enlarged view, between the walls 105 of the respective housing members 10, 10A, 10B and the adjacent housing members 10, 10A, 10B, 10C along the arrangement direction A, a receiving opening 102 is constructed for each terminal 1, 1A, 1B. Here, each wall 105 is constructed with an edge segment 109 extending obliquely to the insertion direction E and the vertical direction V, the edge segment pointing outward with the edge 109B and not covered outward by the outer casing 30, so that the operating element 14 can move relative to the receiving opening 102 with the operating segment 141.

[0122] exist Figure 15 and Figure 16 In the operating position shown, the outer surface 148 (with the operating section 141 pointing outward from this outer surface) extends parallel to the edge 109B of the edge section 109. Here, the outer surface 148 is substantially flush with the edge 109B of the edge section 109, such that the operating section 141 does not substantially protrude outward from the edge section 109 in a direction perpendicular to the longitudinal extension of the edge 109B.

[0123] The outer surface 148 points outward and is always accessible from the outside; however, the inner surface 149 of the operating section 141, which faces away from the outer surface 148 and points inward toward the interior of the housing 10, is only accessible according to... Figure 1 and Figure 2 as well as Figure 11 It can be accessed from the outside in the unoperated position, but according to Figure 3 and Figure 4 as well as Figure 15 and Figure 16 The operating element 14 cannot be accessed from the outside while in its operating position. Therefore, in the operating position of the operating element 14, the user cannot grab the head of the operating section 141, which is defined by the outer surface 148 extending outward and the inner surface 149 extending inward, from below to remove the operating element 14 from the operating position.

[0124] Since the operating section 141 is submerged in the receiving opening 102 in the operating position of the operating element 14, the inner surface 149 cannot be touched from the outside in the operating position of the operating element 14, so that torque cannot be applied to the operating section 141 to remove the operating element 14 from the operating position.

[0125] A tool engagement portion 146 is formed at the free end of each operating section 141, into which a tool, such as a screwdriver, can engage, particularly to position the operating element 14 in a non-operating position. Figure 1 and Figure 2 ) Transfer to the operating position ( Figure 3 and Figure 4 as well as Figure 15 and Figure 16)middle.

[0126] In the region of the free end of each operating section 141, protrusions 145 are formed on both sides of the operating section 141. These protrusions project along the arrangement direction A and are inserted into the notches 109A of the edge section 109 on the wall 105 in the operating position, as if by Figure 15 and Figure 16 As can be seen, these protrusions 145 can be used to widen the operating section 141 at the free end, particularly in the area of ​​the tool engagement 146, so that the tool engagement 146 can be designed to be so wide that common tools, such as screwdrivers, can engage with the tool engagement 146.

[0127] Ribs 147 are formed on the outer surface 148, which form a discontinuity on the outer surface 148 and are used to prevent the hand from slipping when gripping the outer surface 148.

[0128] As this comes from Figure 16 As can be seen, in the operating position of the operating element 14, the operating section 141 is substantially flush with the envelope surface of the wiring device 3, which corresponds to the imaginary body that surrounds the wiring device 3 in an enveloping manner. Because the operating section 141 does not protrude outward from the housing 30, or only slightly, when the operating element 14 is in the operating position, the user cannot easily remove the operating element 14 from the operating position. The wiring of the electrical wire can only be performed by inserting the electrical wire 2 into the insertion opening 100 of the terminals 1, 1A, and 1B along the insertion direction E, and then the terminals 1, 1A, and 1B are automatically triggered, thereby removing the operating element 14 from the operating position.

[0129] Since the user cannot easily operate the operating element 14 manually from the operating position, erroneous operation is largely eliminated. Therefore, the user intuitively understands that the wire 2 needs to be wired by inserting the wire into the plug opening 100 of the corresponding terminals 1, 1A, 1B. Here, the operating element 14 is automatically triggered by the trigger element 13, without requiring the user to operate the operating element 14 specially.

[0130] Wiring device 3 can be supplied to the customer by the manufacturer, for example, with operating element 14 in the operating position.

[0131] The ideas underlying this invention are not limited to the aforementioned embodiments, but can also be implemented in other ways.

[0132] In the embodiments described above, all terminals of the wiring device are implemented through spring connectors with the same function, but this is not mandatory. Therefore, the terminals of the wiring device may also differ from each other in their operation and construction.
