TECHNICAL FIELD

[0001] The invention relates to a conductor connection terminal for connecting electrical conductors, having a busbar and a clamping spring, which forms a clamping point with the busbar for clamping a conductor, and having a functional element which comprises a retaining section and a release section. BACKGROUND

[0002] From DE 10 202 01 19372 B4 a conductor connection terminal is known, which has an insulating material housing having a conductor insertion opening for accommodating an electrical conductor, and having a busbar, which has a passage opening for a conductor, and having a clamping spring, which forms a clamping point with the busbar for an electrical conductor. A retaining element for retaining a clamping leg of the clamping spring in an open position of the clamping point has a latching element which latches with a latching element on the clamping leg and a release section which can be actuated for releasing the latching, for example by means of a conductor. SUMMARY

[0003] The invention solves the technical problem of providing an especially suitable electrical conductor connection terminal. The technical problem is solved according to the invention by the features of independent claims 1, 2 and 15. Advantageous improvements and expanded designs are the subject matter of the dependent claims.

[0004] The conductor connection terminal for connecting electrical conductors has a busbar and a clamping spring. The clamping spring, which forms a clamping point with the busbar for clamping a conductor, preferably has a contact leg and a clamping leg which can be moved from a clamped position to an open position. Here and in the following, a conductor is understood to mean, in particular, a (conductor) core of a (electric) line, which is formed by one or more electric lines made of an electrically conductive material, for example copper, and is surrounded by a conductor sheath made of an insulating material. The busbar is made of, in particular, copper or a copper material. The busbar can also be coated, for example, tinned, in particular. The clamping spring is preferably made of spring steel, in particular as a stamped and bent part, which is suitably designed as a leg spring or has a spring bow with a contact leg and a clamping leg and a connecting leg.

[0005] In a suitable embodiment, the conductor connection terminal has a functional element which is provided as a separate part. In particular, the clamping spring and the functional element are separate parts. Further advantageously, the functional element, in particular as a spring element, is made of spring steel, suitably as a stamped and bent part. The functional element can also consist of a plurality of sections, which consist, for example, of different metals or can also be made of metal or plastic. Furthermore, the functional element can have recesses, in particular in at least one bending point. This results in a bending point having an advantageously small bending radius or having a reduced bending stiffness.

[0006] A functional element arranged (positioned) behind the back of the busbar or behind the passage opening in the busbar has a holding or latching section for holding the clamping leg in its open position and a release section for releasing the clamping leg, the clamping leg being releasably latched with the latching section, and has a contact section. With the contact section, the functional element is supported on a plug-in section of a contact leg of a clamping spring provided on the back of the busbar or on a wall or flange section or on a catch in the busbar.

[0007] The trigger section preferably interacts with the conductor or can be actuated with the conductor to release the latching connection. The clamping leg of the clamping spring is elastically moved from the open position into a clamping position or closed position (latch position), in which the clamping leg forms a clamping point with the busbar with or without a conductor being clamped or clamped in contact.

[0008] In an advantageous refinement, the conductor connection terminal additionally or alternatively has a wall element and / or an actuating or swing element, in particular lever-like, which is coupled or can be coupled to the clamping leg to move it into the open position. In an advantageous embodiment, the wall element has at least one wall-side bearing contour for a corresponding bearing section of the actuating or swing element. In particular, the wall-side bearing contour is shell-like or circular-arc-shaped.

[0009] The actuating or swing element advantageously has two parallel bearing arms, and the busbar has corresponding recesses parallel to one another, which are passed through or bridged by the bearing arms of the actuating or swing element. When the actuating or swing element is coupled to the busbar, the bearing arms are located in or fit into the recesses on the busbar side.

[0010] In an advantageous embodiment, the conductor connection terminal has a busbar with a passage or passage opening for the conductor to be clamped. The preferably circumferentially closed passage or passage opening is suitably designed as a channel, in particular by a flange stretch or by a material channeling as a material channel, or is formed therefrom. Alternatively, the passage or passage opening in the busbar can be produced by a punched edge region or respective edge region of a punched opening.

[0011] The edge side opposite the passage opening and the clamping point, the busbar has a wall or flange section and a plug-in opening spaced apart therefrom, through which or into which the contact leg of the clamping spring is inserted or can be inserted by a plug-in section. The clamping point on the busbar side is also advantageously formed by the wall or flange section, in particular the channel or one channel. The respective wall or flange section is preferably formed or profiled from the busbar, in particular by profiling, for example a 90° bend (profiling, bending).

[0012] According to a suitable refinement, the busbar has, in addition or alternatively, at least one, in particular shell-like or half-shell-like, bearing contour for a corresponding bearing section of an, in particular, rod-like actuating or oscillating element. The busbar-side bearing contour is advantageously provided on both sides in the longitudinal direction of the busbar and is preferably provided on the outside or edge of the passage or through opening, which is preferably arranged spaced apart in the longitudinal direction of the busbar between a wall or flange section and the insertion opening.

[0013] In an advantageous refinement, the functional element arranged behind the passage opening of the busbar in the conductor insertion direction has, in addition or alternatively, a holding or latching section for holding or latching the clamping leg in the open position. The functional element advantageously has a triggering section for releasing the clamping leg held releasably on the holding element or for releasing the latching connection to the clamping leg of the clamping spring. The functional element expediently has a contact section with which the functional element bears on the plug-in section of the contact leg of the clamping spring or on a wall or flange section of the busbar or on a catch in the busbar.

[0014] According to an advantageous embodiment, the conductor connection terminal designed and provided for connecting an electrical conductor has an insulating material housing having a conductor connection channel for the conductor, which is accessible via an insertion opening, and having a busbar and a clamping spring and an actuating or oscillating element. The clamping spring advantageously has a clamping leg which has a clamping edge at the leg end side, which forms a clamping point for the conductor with the busbar, in particular with a busbar side wall or flange section.

[0015] The busbar expediently has a passage or through opening for the conductor. The passage or through opening is preferably closed in the circumferential direction. The passage or through opening can also be formed by a U-shaped busbar which forms at least a first wall, leg or flange section, in particular as clamping point, and an opposite second wall, leg or flange section.

[0016] In an advantageous refinement, the conductor connection terminal has an actuating or oscillating element, in particular an oscillating lever or rocker arm, for moving or oscillating the clamping leg of the clamping spring to create an open clamping point. It is particularly advantageous to provide a latching element which interacts with the clamping spring or its clamping leg to create a latching connection which can be released by a triggering element when the clamping point is open.

[0017] According to a suitable refinement, the conductor connection terminal has, in addition or alternatively, a wall element or at least one wall element, in particular a pocket-like, cap-like or cover-like housing element or housing section. The housing element is preferably arranged or positioned behind the busbar or behind the passage or through opening thereof in the conductor insertion direction. The housing element is expediently accommodated in or can be inserted into the insulating material housing.

[0018] The conductor connection terminal advantageously has a functional element which is designed and configured for establishing or releasing the latching connection between the clamping leg and the holding or latching section. The functional element is advantageously configured as a separate functional element, in particular separate from the clamping spring. It is particularly advantageous if the functional element is designed and configured for force-transmitting abutment or support on the busbar, in particular on a wall or flange section or flange section or notch portion or notch portion or contact leg or leg end side plug-in section or plug-in section of the busbar, preferably outside the busbar through opening.

[0019] Suitably, in the latching connection of the clamping leg of the clamping spring pre-tensioned, the respective tension or restoring force is transmitted into or introduced or guided into the busbar via the functional element, in particular directly or indirectly via the contact leg of the clamping spring. Advantageously, the coupling of the separately configured functional element to the clamping spring can enable or cause the elastic release of the clamping leg from the latching connection, in particular by the conductor, as a result of the actuation of the trigger section. The non-deflectable or immovable support or holding of the functional element is provided on the bar-side support contour, for example also by one section of the contact leg. Advantageously, the particularly immovable support or holding of the functional element is designed and configured outside the busbar region facing away from the clamping site in the passage or through opening or on the outside of the busbar-side or flange section.

[0020] Suitably, the latching section of the functional element has at least one latching element or latching contour for creating a latching connection with the clamping leg of the clamping spring. Alternatively, in addition or instead, the clamping leg of the clamping spring has at least one, in particular pin-like or tab-like, latching element which engages behind the respective contact edge or latching contour, in particular the latching section, of the functional element to form a latching connection or releasable latching connection.

[0021] The clamping leg of the clamping spring advantageously has a curved section which is oriented in the direction of the clamping site and has a clamping edge on the free end side. In particular, the at least one latching element of the clamping leg of the clamping spring extends at an angle to the curved section with the free end side clamping edge, which is oriented in the direction of the clamping site. It is particularly advantageous if the functional element has a recess to form the at least one contact edge or latching contour and / or the clamping leg of the clamping spring has at least one latching element which engages behind the respective contact edge or latching contour of the functional element to form a latching connection.

[0022] Suitably, the trigger section of the functional element is connected to the latching section via a bending point, in particular a knee-shaped bending point. The trigger section of the functional element can also advantageously be designed approximately L-shaped, with a relatively long L-shaped leg, in particular leading to the bending point or the bending point, and with a relatively short L-shaped leg, in particular a pedal-like, for the operating lever of the electrical conductor. The latching section of the functional element is in particular advantageously provided in the region of the bending point connected to the trigger section, in particular for a positive or releasable latching connection with the clamping leg of the clamping spring. In particular, the latching section of the functional element is provided on the free end or on the side of the free end facing away from the trigger section or along the functional element behind the bending point.

[0023] According to an advantageous embodiment of the functional element, the contact section is in particular preferably configured L-shaped. Alternatively, the contact section is Z-shaped or U-shaped. The contact section has a contact leg oriented parallel to the busbar. It is suitably resting on the busbar, preferably on the outside of the or one passage opening for the electrical conductor.

[0024] In a suitable refinement, the contact section of the functional element has additionally or alternatively a contact leg oriented in the direction of the trigger section and / or the wall or flange section of the busbar. For example, the contact section of the functional element is seated with a contact or support contour on the side (outer side or contact side) of the wall or flange section facing away from the passage or passage opening.

[0025] The contact section of the functional element can also have a contact leg oriented in the opposite direction to the trigger section or the wall or flange section of the busbar. An advantageous embodiment of the conductor connection terminal provides that the contact section of the functional element engages behind a plug-in section of the contact leg or a recess of the busbar side with a contact or support contour provided on the back of the busbar.

[0026] In an advantageous refinement, the contact leg or one of the contact legs of the contact section of the functional element has additionally or alternatively an opening, for example a recess or recess, which has a contact or latching contour. This engages behind a plug-in section of the contact leg of the clamping spring or one or more recesses in the busbar, in particular forming a self-supporting system when the clamping spring is latched with the functional element.

[0027] According to a suitable embodiment of the busbar, the passage opening is designed as a channel to form a channel flange with the wall or flange section and / or a further wall or flange section provided or formed on the busbar side or narrow side of the busbar opposite the lead-in or insertion opening for the conductor.

[0028] Advantageously, a pocket-, cap- or lid-like housing element, in particular a housing cap, is provided which is arranged behind the passage opening of the busbar in the conductor insertion direction.

[0029] The housing element forms an insertion and / or receiving space and at least one wall element. Preferably, the housing element is designed and configured to preferably fully accommodate the functional element. Suitably, the housing element has a connecting pin that passes through an opening or punch in the functional element when the functional element is inserted into the housing element. The opening or punch is preferably located in the area between a locking element or the contact segment between the locking element and the functional element.

[0030] In the assembled state of the conductor connection terminals, especially in the pre-assembled state of the assembly with clamping springs and busbars, as well as functional elements and oscillating elements, the housing element is advantageously held on the busbar and / or on the wall or flange section or on the channel flange of the busbar. In particular, the housing element at least partially or in some areas surrounds the channel flange, preferably at least in the passage or through-opening area on the back of the busbar, in said or each wall or flange section. Preferably, the housing element with the functional elements inserted therein is inserted as an assembly into the insulating housing, especially together with the busbar and / or with the clamping spring.

[0031] Particularly advantageous is that at least one wall element or housing element has a support section, particularly in the form of an arc, a circle, a shell, or a semi-shell. The corresponding support profile of the actuating or oscillating element is located in or engaged within the support section. The oscillating element is suitably coupled to the actuating element, which is preferably designed and / or effectively designed as a pressing element. It is slidably guided within an insulating housing, particularly in a guide channel.

[0032] In an advantageous embodiment of the conductor connection terminal, the busbar has at least one support profile, and the actuating or oscillating element has a corresponding support profile. The support profile on the busbar side is preferably disposed on the back side of the busbar along the conductor insertion direction, and preferably disposed outside the opening. In particular, the support profile is disposed in the longitudinal direction of the busbar or on opposite longitudinal sides of the busbar.

[0033] The advantages achieved by this invention are particularly the provision of a suitable actuation mechanism for opening a conductor connection terminal or a clamping portion between a clamping spring and a busbar for a conductor connection terminal. It is especially advantageous that, additionally or alternatively, a suitable mechanism is provided for locking the clamping leg of the clamping spring in the open position of the clamping portion or for releasing such locking connection.

[0051] Components with the same reference numerals in the accompanying drawings may correspond to each other or may be designed similarly. Detailed Implementation

[0052] Figure 1 and Figure 2 A conductor connection terminal 1 is shown, housed within a housing made of a non-conductive material, particularly plastic, hereinafter referred to as an insulating material housing 2. The conductor connection terminal 1 is intended and provided for connecting an electrical conductor 3 (…). Figure 10 and 13 ).about Figure 1 and Figure 2 The components and / or features of the conductor connection terminal 1 shown may be completely or partially identical.

[0053] The conductor connection terminal 1 has a busbar 4 and a clamping spring 5, which together with the busbar 4 form a clamping portion for the conductor 3. The conductor 3, not shown in the figure, is guided to or enters the clamping portion via the insertion port 7 and conductor connection channel 8 of the (insulating material) housing 2 and along the conductor insertion direction L, through or in the area of ​​the passage of the busbar 4 or through the opening 40.

[0054] The conductor connection terminal 1 has a functional element 6, which is coupled to or can be coupled to a clamping spring 5 to establish a releasable locking connection. The functional element 6 is arranged along the conductor insertion direction L behind the passage or through opening 40 of the busbar 4, or on the back side of the busbar 4 relative to the insertion port 7. The functional element 6 is designed as a flexible, flat, strip-shaped spring element.

[0055] See also Figure 3The clamping spring 5 has a clamping leg 50 and a contact leg 51, the contact leg 51 being connected to the clamping leg 50 via a spring bow 52. The clamping leg 50 has a curved section 53 at its leg end facing the spring bow 52, ​​the curved section having a clamping edge 54 on its free end side. In an embodiment, the clamping leg 50 of the clamping spring 5 has two parallel pin-shaped or plate-shaped locking elements 55, which extend at an angle to the curved section 53 oriented along the direction of the clamping portion or are bent along the direction of the functional element 6.

[0056] An actuating surface 56 is formed on the clamping leg 40, preferably in the form of a laterally projecting tab, which is used to absorb the actuating force from the actuation mechanism of the conductor connection terminal 1. The contact leg 51 has a plug-in section 57 at its leg end facing the spring bow 52. The clamping spring 5 is positioned or fixed in the housing 2 by means of the housing arch 9 engaged in the spring bow 52.

[0057] See also Figure 4 The functional element 6 has a holding or locking section 61, a trigger section 62, and a contact section 63. The trigger section 62 is connected to the locking section 61 via a bent portion 64, which preferably has a recess 65. The trigger section 62 is generally L-shaped, having a relatively long L-shaped leg 62a and a relatively short L-shaped leg 62b leading to the bent portion 64, serving as a pedal-like operating lever for the electrical conductor 3. The locking section 61 has opposing notches at its transition to the bent portion 64 to form a locking profile 66.

[0058] The contact segment 63 is generally L-shaped, or generally Z-shaped when connected to the locking segment 61, with its contact leg 63a oriented parallel to the busbar 4. In this variation of the functional element 6, the contact leg 63a is oriented in the opposite direction to the L-leg 62b of the trigger segment 62. The contact leg 63a of the functional element 6 has an opening or cutout 67 to form a contact or locking profile 68. The cutout 67 extends into the locking segment 61 through a first bending region 69a and a second bending region 69a, particularly to reduce the bending stiffness of the functional element 6 or the release force required to release the clamping leg 50 of the lock.

[0059] See also Figure 5 Busbar 4 has an opening 40 for passage or through-passage of conductor 3. The opening 40 is designed as a channel. On the relatively narrow sides and edges of the opening 40, busbar 4 has wall or flange segments 41, 42. Preferably, the corresponding wall or flange segments 41, 42 formed by the channel extend on the back side of the busbar facing it or along the direction of the functional element 6. Figure 2 In the clamping position shown, the clamping part is formed between the wall or flange section 41 of the busbar 4 and the clamping edge 54 of the clamping leg 50.

[0060] Outside the passageway or through the opening 40 and at a distance from the wall or flange section 42 opposite the clamping part, the busbar 4 has an insertion port 43 for receiving the contact section 51 of the clamping spring 5. Preferably, also outside the passageway or through the opening 40 and in the area of ​​the wall or flange section 42 opposite the clamping part, the busbar 4 has a shell-shaped or arcuate support profile 44 on the edge of the opposite elongated side. Between the respective support profile 44 and the insertion port 43, the busbar 4 advantageously has a notch 45 on the edge of the opposite elongated side.

[0061] Refer again Figure 1 and Figure 2 The wall element 10 is arranged behind the passage or through opening 40 of the busbar 4 along the conductor insertion direction L. The wall element 10 preferably covers or is located in the housing recess 11 of the insulating material housing 2. The wall element 10 has a shell-shaped or arcuate support profile 20 that opens toward the busbar 4.

[0062] Wall element 10 is preferably Figure 7 The shown is a cap-shaped or cover-shaped housing segment or component of housing element 12. It is inserted into or can be inserted into the housing recess 11 of the insulating material housing 2. The outer contour of housing element 12 is adapted to the inner contour of recess 11, in particular such that housing element 12 is positioned in recess 11 with the smallest possible clearance. The cap-shaped or cover-shaped housing segment as housing element 12 is intended and configured to accommodate functional element 6. Housing element 12 has a connecting pin 12a between opposing support contours 20 in the corresponding wall element 10, which passes through the opening or punch 67 of functional element 6 when functional element 6 is inserted.

[0063] A swing element 13 (hereinafter also referred to as a rocker arm) is mounted on the busbar 4 and in the wall element 10 and is mechanically coupled to the clamping leg 51 of the clamping spring 5. The swing element 13 interacts with an actuating element 14 designed as a pressing element, which is slidably guided in a guide channel 15 within the insulating housing 2. The swing element 13 is used to open the clamping leg 51 at the clamping position or to release the clamping leg 50 from the clamping position. Figure 2 The clamping position shown swings to Figure 9 The opening position is shown.

[0064] See also Figure 6 and Figure 8The rocker arm 13 has a rod section 13a serving as a swing element, which is coupled or can be coupled to the pressing member 14. The rocker arm 13 has mutually parallel contact legs 13b, which are disposed on the actuating surface 56 of the clamping leg 50 of the clamping spring 5. The rocker arm 13 has two mutually parallel support legs or support arms 13c, which are guided or pass through the recess 45 of the busbar 4. The corresponding support legs 13c interact on the one hand with the support profile 20 of the wall element 10 and on the other hand with the support profile 44 of the busbar 4, preferably forming support members and / or counter-support members for the rocker arm 13.

[0065] The corresponding support arm or support leg 13c has a disc-shaped support profile 21, which is inserted into a corresponding, especially shell-shaped support profile 20, which serves as a support section of the wall element 10. The support leg 13c of the rocker arm 13, which serves as a swing element, has a support section 22, especially mushroom-shaped, which is placed in a corresponding, especially arched, grooved, or shell-shaped support profile 44, which serves as a support section of the busbar 4.

[0066] As by Figure 6 and Figure 9 as well as Figure 10 As can be seen, the locking element 55 of the clamping leg 50, in its open position, engages with the locking profile 66 of the functional element 6 when a locking connection is established between the clamping leg 50 of the clamping spring 5 and the locking section 61 of the functional element 6. In other words, the locking element 55 of the clamping leg 50 engages behind the locking profile 66 of the functional element 6. The locking connection between the clamping leg 50 and the locking section 61 can be released by actuating the trigger section 62 using the conductor 3. The contact leg 63a of the contact section 63 of the functional element 6 is disposed on the busbar 4 outside the opening 40. The contact or locking profile 68 of the cutout 67 of the contact section 63 of the functional element 6 engages behind the insertion section 57 of the contact leg 51 of the terminal spring 5, which passes through the insertion port 43 of the busbar 4.

[0067] What is particularly advantageous is that, Figure 6 The diagram shows a busbar 4, a clamping spring 5, a functional element 6, a swing element 13, and according to... Figure 8 The assembly of housing element 12, which is mounted on busbar 4 or its wall or flange sections 41, 42, can be installed into insulating housing 2 with particular ease.

[0068] Figure 11 Functional element 6 or a variation thereof is shown. In Figure 12 Functional element 6, visible in the assembled state when inserted into housing element 12, Figure 13 The components are shown in their loaded state together with the busbar 4, the clamping spring 5, and the lever-type oscillating element 13.

[0069] Functional element 6 further includes a holding or locking section 61, a trigger section 62, and a contact section 63. The trigger section 62 is connected to the locking section 61 via a curved portion 64 having a notch 65. The L-shaped trigger section 62 has an L-shaped leg 62b serving as a pedal-shaped operating lever for the electrical conductor 3. The locking section 61 has a corresponding notch at its transition to the curved portion 64 to form a locking profile 66.

[0070] The contact segment 63 is generally L-shaped, and its connection to the locking segment 61 is generally U-shaped. The contact leg 63a is oriented parallel to the busbar 4, and in this variation of the functional element 6, the contact leg 63a is oriented along the direction of the L-leg 62b of the trigger segment 62. The contact leg 63a of the functional element 6 has a notch 67 in the locking segment 61 through which the connecting pin 12a of the housing element 12 passes when the functional element 6 is installed. The notch or notch 67 extends in the (second) bending region 69b into the connecting segment 70 of the U-shaped contact segment 63.

[0071] The connecting segment 70 connects to or transitions into the contact leg 63a via a (first) curved region 69b. The contact leg 63a has a contact edge 71 at its end or forms a contact edge 71 on its free end side. Figure 13 In the assembled state shown, the functional element 6 is supported on the sidewall or flange section 42 of the busbar by the contact edge 71. The contact edge 71 is located on the outside of the wall or flange section 42 opposite to the opening 40. The outside faces the insertion section 57 on the back of the busbar located in the insertion port 43 of the busbar 4.

[0072] Figure 14 Another variation of functional element 6 is shown, in which contact leg 63a interacts with snap 46 in busbar 4. (See diagram) Figure 15 As shown, the latch 46 located on the back side of the busbar 4 facing the functional element 6 is... Figure 16 The contact segments 63 of the functional element 6 in the shown joint connection interact with each other.

[0073] Figure 16 The corresponding assembly with busbar 4, clamping spring 5, and functional element 6 is shown again. A latch 46 is formed on the back side between the wall or flange section 42 and the insertion port 43 on the busbar 4. The latch 46 preferably forms a wedge-shaped or ramp-shaped latching profile with contact or locking edges 47.

[0074] Basically corresponds to according to Figure 11The modified functional element 6 has an opening or recess 72 in the contact leg 63a of the contact section 63. The ramp-shaped or wedge-shaped snap fastener 46 of the busbar 4 engages or snaps into it to form a joint connection, especially as a locking connection. The functional element 6 is reliably supported on the busbar 4 or clamped and fixed by a locking connection with the clamping spring 5.

[0075] In summary, the present invention relates to a conductor connection terminal 1 having a busbar 4 and a clamping spring 5 with a contact leg 51 and a clamping leg 50, and a separate functional element 6 having a locking section 61 for holding the clamping leg 5 in an open position, a trigger section 62 for releasing the locking connection with the clamping leg 50, and a contact section 63. The functional element 6 is supported by the contact section on the insertion section 57 of the contact leg 51 located on the back side of the busbar 4, or on the wall or flange section 42, or on the latch 46 of the busbar 4.

[0076] In the conductor connection terminal 1 shown and described, it is advantageously designed to be small in size or for connecting an electrical conductor 3 with the smallest possible conductor cross-section. The open clamping portion can remain open without further action of the actuating element 14. The clamping portion can also be closed without the actuating element 14, preferably by means of the conductor 3 itself.

[0077] The (conductor) connection or terminal can be advantageously used in such a way that the user actively opens the corresponding (conductor) clamping part by means of, for example, a lever-shaped or button-shaped actuating element 14, so as to guide the conductor 3 to or into the clamping part. The actuating element 14 can then be released, thereby closing the clamping part and fixing the conductor 3 to the busbar 4 by clamping spring pressure and making electrical contact. The conductor connection terminal 1 can be designed for a single, preferably single-wire or multi-wire, especially thin-wire, electrical conductor 3, or it can be designed as a connection terminal for multiple such conductors 3.

[0078] The claimed invention is not limited to the embodiments described above. Instead, those skilled in the art can derive other variations of the invention within the scope of the disclosed claims without departing from the subject matter of the claimed invention. Specifically, within the scope of the disclosed claims, all the individual features described in conjunction with the various embodiments can also be combined in other ways without departing from the subject matter of the claimed invention.
