Description

[0001] The invention relates to a conductor terminal for connecting an electrical conductor, with a busbar and with a clamping spring forming a clamping point with the busbar for clamping the conductor.

[0002] Such a conductor terminal or connection terminal is typically used in such a way that a user must actively open each terminal using a lever- or push-button-like actuator before a conductor can be inserted into the terminal. The actuator is then released, closing the terminal and securing the conductor to the busbar by spring pressure, thus establishing electrical contact. The conductor terminal can be designed for a single, preferably single- or multi-stranded, particularly fine-stranded, electrical conductor, or as a connection terminal for several such conductors.

[0003] It is often desirable, especially in the case of small conductor terminals with the smallest possible dimensions or conductor terminals for connecting electrical conductors with the smallest possible cross-sections, that the open clamping point remains open without further action of the actuating element and that the clamping point can be closed without an actuating element, preferably by means of the conductor itself.

[0004] From DE 10 2020 119 372 B4, a conductor terminal is known with an insulating housing having a conductor entry opening for receiving an electrical conductor and with a busbar having a through-opening for the conductor, as well as with a clamping spring which, together with the busbar, forms a clamping point for the electrical conductor. A retaining element for holding a clamping leg of the clamping spring in an open position of the clamping point has a locking element that engages with a detent element on the clamping leg and a release section, which can be actuated, for example, by means of the conductor, for releasing the locking mechanism.

[0005] The invention is based on the objective of providing a particularly suitable electrical conductor connection terminal. In particular, a suitable actuating mechanism for opening a clamping point between a clamping spring and a busbar and / or a suitable mechanism for locking a clamping leg of the clamping spring in an open position of the clamping point or for releasing such a locking connection is to be provided.

[0006] This problem is solved according to the invention by the features of dependent claims 1 to 6. Advantageous embodiments and further developments are the subject of dependent claims.

[0007] The conductor terminal, designed and configured for connecting an electrical conductor, has a busbar and a clamping spring, which together with the busbar form a clamping point for attaching the conductor. Here and in the following, a conductor is understood to be, in particular, a conductor core of an (electrical) line formed by one or more wires made of electrically conductive material, for example, copper, and enclosed by a conductor sheath of insulating material. The busbar is preferably made of copper or a copper-based material. The clamping spring, which is suitably designed as a torsion spring or with a contact leg and a clamping leg as well as a spring arc connecting the legs, is preferably made of spring steel, in particular as a stamped and bent part.

[0008] In a suitable embodiment, the conductor terminal has at least one wall element that is positioned or arranged behind a feed-through or through-opening in the busbar, provided for the conductor to be clamped, in a conductor insertion direction. Advantageously, the wall element defines an insertion space for the conductor, particularly within an insulating housing of the conductor terminal. Additionally or alternatively, the at least one wall element has a receiving area for a functional element that is coupled or can be coupled to the busbar and / or the clamping spring, and / or defines such a receiving space. The wall element(s) can be a component of a housing part (housing element), for example, a pocket-, cap-, or cover-like element, particularly forming the receiving area or a receiving space for the functional element or a number of functional sections.The functional element, in particular a functional or triggering section, can also be advantageously mechanically coupled to the conductor.

[0009] In a suitable embodiment, the conductor connection terminal, which is designed with at least one wall element, has a pivoting element, in particular a lever- or rocker-lever-like element. The pivoting element is preferably mechanically coupled to a clamping leg of the clamping spring for opening the clamping point or for clamping at the clamping point. The pivoting element is advantageously mounted on the wall element. Additionally or alternatively, the pivoting element is mounted on the busbar and / or in or on a section (bearing or functional section, bearing leg) of the functional element, preferably as a counter bearing.

[0010] In an advantageous embodiment, a conductor connection terminal comprising at least one wall element and a functional element has a busbar with a feed-through or through-opening for the conductor to be clamped. The functional element is arranged at least partially, or preferably completely, behind the through-opening of the busbar or on the back of the busbar in the conductor insertion direction. The functional element suitably has a detent section, in particular with a detent element, for creating a releasable detent connection with the clamping leg or leg of the clamping spring.

[0011] Additionally or alternatively, the functional element has a release section for releasing the detent connection between the clamping leg of the clamping spring and a detent element, in particular the detent section of the functional element. Additionally or alternatively, the functional element has a section (bearing or functional section) for mounting a pivot element, in particular a lever-like element, which is mechanically coupled to the clamping spring or its clamping leg for opening the clamp at the clamping point.

[0012] According to a suitable embodiment, in a conductor connection terminal designed with a functional element arranged preferably at least partially behind a through- or through-opening of the busbar in the conductor entry direction, the busbar has at least one wall or collar section. This is suitably arranged on or in the area of ​​the through- or through-opening of the busbar.

[0013] The wall section (collar section) is advantageously oriented towards the functional element in the conductor entry direction or provided on the rear side of the busbar. The wall or collar section is preferably formed or shaped from the busbar, particularly by forming, for example, a 90° bend. It is especially advantageous if the through-opening of the busbar is designed as a through-hole, particularly by collar forming or tensile-compression forming, with the collar forming or incorporating the wall section.

[0014] The functional element suitably comprises a detent section for creating a releasable detent connection with the clamping leg of the clamping spring, as well as a contact section. This contact section can advantageously be formed by a contact edge between parallel bearing legs of the functional element. The contact section, or contact edge, rests against the side of the wall or collar section facing away from the passage or opening (outer or contact side). Additionally or alternatively, the clamping spring, or its contact leg, rests against the side of the wall or collar section facing the passage or opening (inner side). Preferably, the contact leg is supported on the wall or collar section, expediently on this inner side.

[0015] According to an advantageous embodiment of the conductor connection terminal, which comprises a busbar, a clamping spring, and a pivoting element, an insulating housing with a conductor connection channel accessible via an insertion opening is provided. The busbar suitably has a through-opening or a through-opening through which the conductor passes during connection. The clamping spring, or its clamping leg, has a clamping edge on its leg or free end. This edge, together with the busbar, particularly with a wall or collar section on the busbar side, forms a clamping point for the conductor. The pivoting element, which is designed or acts as a pivot or toggle lever, is provided or configured to displace or pivot the clamping leg of the clamping spring, thereby creating an open clamping point.

[0016] Additionally or alternatively, a locking element interacting with the clamping spring or its clamping leg is provided to create a locking connection that can be released by means of a release element when the clamping point is open. Additionally or alternatively, a pocket-, cap-, or cover-like housing part or element with a number of wall elements is provided. The housing part or element is suitably arranged (positioned) behind the busbar or its through- or through-opening in the conductor entry direction. Advantageously, the housing part or element is accommodated in or can be inserted into an insulating housing.

[0017] Additionally or alternatively, a functional element is provided for the, in particular pivotable or rotatable, mounting of a pivoting or actuating element and / or for establishing or releasing the locking connection and / or for force-transmitting contact with the busbar or with a wall or collar section, particularly with or in the area of ​​a through-opening of the busbar. Preferably, the functional element has corresponding functional sections for mounting a pivoting element, for establishing the locking connection, for releasing the locking connection, for force-transmitting contact with the busbar or with a wall or collar section of the busbar and / or with a wall contour of the wall or housing element.

[0018] In an advantageous embodiment, the housing element is held on the busbar and / or on the wall or collar section or on the busbar's pass-through collar. In particular, the housing element can be mounted on the busbar or is pre-assembled. Suitablely, the housing element at least partially or completely surrounds the busbar's pass-through collar. This allows for particularly advantageous pre-assembly of the housing element, especially with components and / or elements of the conductor connection terminal already incorporated therein, preferably the functional element.

[0019] The housing element, preferably with the functional element inserted therein and / or together with the busbar and / or together with the clamping spring, is suitably inserted or insertable into the insulating housing. The pocket-, cap-, or cover-like housing element forms an insertion and / or receiving space. Preferably, the pivoting element is coupled to an actuating element, in particular designed as a push button and / or effective. In particular, the actuating element or the push button is slidably guided in a guide channel of the insulating housing.

[0020] Preferably, the housing element forms each of the wall elements, in particular two parallel wall elements for supporting the pivoting element at opposite bearing points or bearing sections. A particularly suitable embodiment provides that the at least one wall element or the housing element has a bearing section or a bearing contour that corresponds to or interacts with a bearing section or a bearing contour of the pivoting element.

[0021] A further development or embodiment provides that the busbar has at least one bearing contour and the pivoting element has a corresponding bearing contour, which corresponds to the bearing contour of the busbar, in particular forming a rotary or pivot bearing. Suitablely, the busbar, particularly in the conductor entry direction on a rail back, preferably in the area of ​​the through-opening, has at least one bearing contour and the pivoting element has a bearing element that engages in the bearing contour of the busbar. Alternatively, the busbar can have a bearing element that engages in a corresponding bearing contour of the pivoting element. The bearing element can be designed as a (stationary) axis or form one around which the corresponding bearing contour slides.

[0022] According to a further development or embodiment, the functional element has a bearing sleeve or bearing eyelet forming the functional or bearing section, with a bearing contour, in particular an arcuate one, and the pivoting element has at least one bearing pin or bearing lug with a corresponding bearing contour. This interacts with the bearing contour of the functional or bearing section, which is preferably integrally formed on or formed from the detent section of the functional element.

[0023] The functional element advantageously features at least one bearing leg extending or arranged laterally to the opening of the busbar, and the pivoting element has at least one corresponding bearing contour. This contour interacts with the bearing leg or with a bearing contour of the bearing leg, preferably forming a counter-bearing for the pivoting element. Suitablely, such a bearing leg is provided on both sides of the opening, extending – in the longitudinal direction of the busbar – over a portion of the length of the opening. This allows for a particularly narrow conductor terminal.The bearing or counter bearing for the pivoting element (rocker arm) formed by means of the bearing leg arranged laterally to the passage opening of the busbar is particularly advantageously located in the conductor insertion direction on the back of the busbar directly below the contact point or attack position of the pivoting element (rocker arm) on the clamping leg of the clamping spring.

[0024] Advantageously, the functional element has a detent section with a detent contour. The detent section is connected via a bend, in particular a knee-like bend, to the release section, which interacts with the conductor or can be actuated or pressurized by it. A recess, in particular a hole-like one, is particularly advantageous in the bend. This allows for a particularly small bending radius between the detent section and the release section.

[0025] Additionally or alternatively, the functional element has an angled section, particularly oriented towards the busbar. Additionally or alternatively, the functional element has a retaining section that interacts with a retaining contour of the wall element or the housing element.

[0026] Additionally or alternatively, the functional element has a detent section or a detent section, in particular angled relative to the release section, with a detent contour or a detent contour, and an angled section adjoining this, in particular directed towards the busbar, as well as a holding section or a holding section adjoining this, which interacts with a holding contour of the wall element or the housing element.

[0027] Advantageously, the angled section of the functional element rests outside the opening of the busbar against a wall or collar section of the busbar opposite the clamping point. Additionally or alternatively, the functional element is held section by section between the busbar and a housing contour of the wall element or the housing element, preferably clamped. This provides particularly advantageous support for the functional element on the busbar or its wall or collar section. This, in turn, enables a particularly efficient force transmission, especially a release force for disengaging a latching connection, via a force chain formed, in particular, by means of the functional element, the busbar, and / or the wall or housing element, into the assembly of busbar and wall or housing element, or via this assembly into the insulating housing.

[0028] Advantageously, a connecting section extending at an angle, particularly a right angle, to the mounting section of the functional element is provided, which fits into or can be inserted into a plug-in contour of the wall element or the housing element. This design of the functional element serves in particular to form and / or improve the force chain.

[0029] A recess is suitably provided in the functional element, particularly in the holding section and / or in an angled section. This advantageously reduces the release force acting via the release section, especially by means of the conductor in the functional element.

[0030] Additionally or alternatively, the functional element, in particular its retaining section, has a recess aligned with an opening of the busbar, and the clamping spring, in particular its contact leg, has a plug-in element, preferably pin-, tab-, or flat-band-like, which engages into the recess of the functional element via the opening of the busbar. Preferably, the retaining section of the functional element is designed as a functional or bearing section or shaped like a bearing sleeve or bearing eyelet for the pivoting element, in particular for supporting at least one corresponding bearing element or bearing pin of the pivoting element.

[0031] Additionally or alternatively, the functional element, in particular the retaining section, has a section parallel to the busbar, particularly one located on the rear side of the busbar in the conductor entry direction. Additionally or alternatively, the functional element, in particular the retaining section, has a section parallel to the busbar and a plug-in section extending at an angle to it, particularly at an acute angle. This plug-in section is inserted into, or can be inserted into, a plug-in contour or groove of the wall element or housing element. The plug-in contour is suitably formed between the housing element and the busbar and / or a housing contour of the insulating housing into which the wall element or housing element is inserted.

[0032] A particularly suitable embodiment or further development of the locking connection between the clamping leg of the clamping spring and the functional element provides that the functional element has a notch or waist forming at least one contact or locking edge. The clamping leg of the clamping spring has at least one locking tab which engages behind the corresponding contact edge, forming the locking connection. Additionally or alternatively, the clamping leg of the clamping spring has a bent section oriented towards the clamping point with a free-end clamping edge, which forms the clamping point with the busbar or the clamped conductor.

[0033] Preferably, the clamping leg of the clamping spring has at least one locking element, in particular a tab-like or flat-band-like element. This locking element, which is preferably provided for creating the locking connection with the functional element or with its locking or contact edge(s), runs perpendicular to the or a bent section oriented towards the clamping point with a free-end clamping edge of the clamping leg of the clamping spring.

[0035] Corresponding parts are each marked with the same reference symbols in the figures.

[0036] The Fig. Figures 1 to 5 show, in different views, a conductor terminal 1, which is enclosed in a housing made of an electrically non-conductive material, in particular a plastic material, hereinafter referred to as an insulating housing 2. The conductor terminal 1 is designed and configured for connecting an electrical conductor 3.

[0037] The conductor connection terminal 1 has a busbar 4 and a clamping spring 5, which together with the busbar 4 form a clamping point 6 for the conductor 3. The conductor 3 is guided through an entry opening 7 and a conductor connection channel 8 of the (insulating) housing 2 in the conductor entry direction L to, or into, the clamping point 6. The clamping spring 5 has a clamping leg 5a and a contact leg 5b, which is connected to the clamping leg 5a via a spring arc 5c. The clamping spring 5 is positioned, or rather fixed in position, in the housing 2 by means of a housing boss 9 that engages in the spring arc 5c.

[0038] The busbar 4 has a through-opening 10 for the conductor 3. The through-opening 10 is designed as a pull-through. A wall element 11 is arranged in a conductor entry direction L behind the through-opening 10. The wall element 11 preferably covers or is embedded in a housing recess 12 of the insulating housing 2. The wall element 11 is preferably a component of a Fig. 9 shown, cap- or lid-like housing part or housing element 13. This is inserted into the housing recess 12 of the insulating housing 2. Suitablely, the outer contour of the housing element 12 is adapted to the inner contour of the recess 12, in particular so that the housing element 13 lies in the recess 12 with as little play as possible.

[0039] A pivoting element 14, hereinafter also referred to as a rocker arm, is mounted on the busbar 4 and in the wall element 11. This pivoting element 14 is mechanically coupled to the clamping leg 5a of the clamping spring 5. The pivoting element 14 interacts with an actuating element 15, designed as a push button, which is movably guided in a guide channel 16 of the insulating housing 2. The pivoting element 14 serves to open the clamping of the clamping leg 5a at the clamping point 6. The clamping point 6 is located in the Fig. 2 shown open clamping between a clamping edge 16 of the clamping leg 5a and a wall or collar section 17 of the busbar 4.

[0040] With a view also to the Fig. The rocker arm 14 has a pivoting lever section 14a which is coupled or can be coupled to the push button 15. The rocker arm 14 has a contact leg 14b which rests against the clamping leg 5a of the clamping spring 5. The rocker arm 14 has a bearing leg 14c which interacts on one side with a bearing contour 18 of the wall element 11 and on the other side with a bearing contour 19 of the busbar 4, preferably forming a bearing and / or a counter-bearing for the rocker arm 14. The bearing leg 14c has a disk-shaped bearing contour 20 which lies in a corresponding, in particular shell-shaped, bearing section as bearing contour 18 of the wall element 11. The bearing leg 14c has a bearing section 21, in particular mushroom-shaped, which lies in a corresponding bearing section, in particular arc-shaped or trough-shaped or shell-shaped, as bearing contour 19 of the busbar 4.

[0041] The conductor connection terminal 1 has a functional element 23. This is arranged in the conductor insertion direction L behind the feed-through or through-opening 10 of the busbar 4, or, with respect to the insertion opening 7, on the rear side of the busbar 4. The functional element 23 is designed as a flexible spring element, for example made of spring steel, preferably in the form of a flat strip.

[0042] With a view also to the Fig. 6 The functional element 23 has a locking section 23a for producing a detachable, in particular in the Fig. 4 and Fig. Figure 7 illustrates the latching connection 22 with the clamping leg 5a of the clamping spring 5. The functional element 23 has a release section 23b for releasing the latching connection 22. The release section 23b can be actuated by the conductor 3 under pressure to release the latching connection 22. The release section 23b is connected to a bending point or a bending section 23c, which is connected to the latching section 23b. The bending point or bending section 23c has a recess or an opening 24 designed as a hole ( Fig. 6) to produce a particularly suitable or small bending radius.

[0043] The functional element 23 has an angled or mounting section 23d, in particular as part of a retaining section 23e, oriented towards the busbar 4. The busbar 4 has a wall or collar section 25, in particular formed by the through-bolt or through-bolt collar, as a mounting surface or mounting contour for the angled section 23d or the retaining section 23e of the functional element 23. The wall or collar section 25 is oriented towards the functional element 23 in the conductor entry direction L. The wall or collar section 25 is provided on the rear side of the busbar 4 facing away from the entry opening 7. The wall or collar section 25 is formed from the busbar 4 by a 90° bend.

[0044] With the angled or contact section 23d, the functional element 23 is preferably positioned against one of the sides (outer or contact side) of the wall or collar section 25 facing away from the passage or through opening 10, such that the angled or contact section 23d and, via this, the functional element 23 on this side (outer side) is supported on the wall or collar section 25 of the busbar 4, in particular in the manner of or as part of a force chain.

[0045] The functional element 23 has a retaining section 23e that interacts with a retaining or support contour 26 of the wall element 11 or the housing element 13, and preferably also with the busbar 4. The functional element, in particular its retaining section 23e, has a contact section 23f that is oriented parallel to the busbar 4 and rests against the busbar 4 on its rear side in the conductor entry direction L or with respect to the entry opening 7, in particular outside of or adjacent to the through- or through-opening 10. In conjunction with the retaining or support contour 26 on the wall or housing side, the retaining section 23e of the functional element 23 is reliably held. In particular, the retaining section 23e of the functional element 23 is clamped between the busbar 4 and the wall element 11 or the housing element 13.

[0046] The Fig. Figure 6 shows the spring element 23 with its functional sections, namely the release section 23b and the detent section 23a, which connects to it via the bending section 23c, as well as the angled section 23d and the contact section 23f of the retaining section 23e. The angled section 23d, hereinafter also referred to as the connecting section, forms the transition between the detent section 23a and the contact section 23f. A bent, in particular acute-angled, plug-in section 23g connects to the contact section 23f. This engages a section 26a of the retaining or support contour 26 of the housing element 13 ( Fig. 9).

[0047] In this embodiment of the functional element 23, the retaining section 23e is approximately U-shaped. Recesses 27, 28, 29 in the bending points between adjacent or neighboring sections 23a, 23d and 23d, 23f or 23f, 23g allow for desirablely small bending radii. This also allows the release force acting via the release section 23b to be reduced by means of the conductor 3 in the functional element 23.

[0048] With a view also to the Fig. Figure 7 shows that in the area of ​​the detent section 23a, two contact or detent edges 30 are formed as a detent contour or detent element by a notch produced in the exemplary embodiment as a waist in the detent section 23a. A detent tab 31 corresponds to each contact or detent edge 30 as a detent contour or detent element on the clamping leg 5a of the clamping spring 5, forming the detent connection 22, by the respective detent tab 31 engaging behind the corresponding detent edge 30.

[0049] As in Fig. As is relatively clearly visible in Figure 7, the clamping leg 5a of the clamping spring 5 has a bent section 32 oriented towards the clamping point 6, which forms the clamping edge 16 at its free end. The respective locking tab 31 runs at an acute angle to this bent section 32 and is approximately perpendicular or right-angled to the locking section 23a of the functional element 23 in the locking connection.

[0050] In Fig. Figure 9 shows the pocket- or cap-like housing element 13. This forms two parallel wall elements 11 for the bearing of the pivoting element 14 at opposite bearing points of each of the wall elements 11 in the form of the arcuate or shell-like bearing contours 18 shown here. A insertion and / or receiving space for the functional element 23 is formed between the wall elements 11. The retaining or support contour 26 is formed on a side wall 33 connecting the wall elements 11.

[0051] In its assembled state, the housing element 13, in particular a portion of the housing opening, encompasses the pull-through collar or the wall or collar sections 17, 25 of the busbar 4, at least partially. This allows the housing element 13, with the functional element 23 embedded therein and other components of the conductor connection terminal 1, in particular the busbar 4, the clamping spring 5 and / or the rocker arm 14, to be provided as a pre-assembled unit or inserted into the insulating housing 2.

[0052] When executing according to the Fig. In figures 10 to 18, the conductor terminal 1', which is enclosed in or encompasses an insulating housing 2', has a busbar 4' and a clamping spring 5', which together with the busbar 4' forms a clamping point 6' for an electrical conductor 3', as well as a clamping leg 5a' and a contact leg 5b', which is connected to the clamping leg 5a' via a spring arc 5c'. In this design, the conductor terminal 1' is comparatively narrow, for example only about 3.5 mm, or is designed with a correspondingly small size or dimensions.

[0053] The busbar 4' has a through-hole or feed-through opening 10'. A wall element 11' arranged behind the through-hole or feed-through opening 10' in a conductor entry direction L is preferably a component of a Fig. 18 cap- or lid-like housing part or housing element 13' shown, which is inserted or can be inserted into the (insulating material) housing 2'.

[0054] A pivoting element or rocker arm 14' is mounted on the busbar 4' and in the wall element 11', which is mechanically coupled to the clamping arm 5a' of the clamping spring 5' at the clamping point 6' for opening the clamping of the clamping leg 5a' and interacts with a slidingly guided push button 15'. The clamping point 6' is located in the Fig. 11 shown, open clamping between a clamping edge 16' of the clamping leg 5a' and a wall or collar section 17' of the busbar 4'.

[0055] The Fig. Figure 16 shows the rocker arm 14' as a pivoting element with a lever section 14a', which is coupled or can be coupled to the push button 15', and with a contact leg 14b' abutting the clamping leg 5a', as well as with a bearing leg 14c'. This leg interacts on one side with a bearing contour 18' of the wall element 11' and on the other side with a bearing contour 34 of the functional element 23', preferably forming a bearing and / or a counter-bearing for the rocker arm 14'. The bearing leg 14c' has a disk-shaped bearing contour 20' which lies in a corresponding, in particular shell-shaped, bearing section as bearing contour 18' of the wall element 11'. The bearing leg 14c' has a bearing section 21', in particular mushroom-head-like or mushroom-head-shaped, which lies (sits) in the corresponding bearing contour 34 of the functional element 23' of the busbar 4.

[0056] In Fig. Figure 15 shows the functional element 23' of the conductor terminal 1'. The functional element 23' has a detent section 23a' for forming a releasable detent connection 22' with the clamping leg 5a of the clamping spring 5', analogous to the embodiment according to Fig. 7. The functional element 23' has a release section 23b' which can be actuated by the conductor 3' under pressure to release the latching connection 22'. The release section 23b' is connected to the latching section 23b' via a bending point 23c'.

[0057] The functional element 23' has a bearing or functional section 23h for supporting the pivoting element 14'. The bearing or functional section 23h is formed by multiple bends to create a bearing sleeve or bearing eyelet 35. On the bearing or functional section 23h, in a bending area between an angled or connecting section 23d' and a contact section 23f' for contact with the busbar 4', the bearing contour 34 for the pivoting element 14', designed as a rocker arm 14', is formed. The bearing or functional section 23h has an opening 35 on a section opposite the contact section 23f'.

[0058] When the functional element 23' is inserted into the housing element 13', an insertion pin 36 of the housing element 13' extends through the opening 35 of the bearing or functional section 23h of the functional element 23'. The bearing or functional section 23h forms, in particular, a retaining section 23e' of the functional element 23' or has the function of such a retaining section 23e', in particular analogous to the embodiment according to Fig. 6, up.

[0059] The functional element 23' has a through-hole 37 that aligns with a through-hole 38 of the busbar 4'. The connecting pin 36 of the housing element 13' has a recess or groove 39 that aligns with the openings 37 and 38. The contact leg 5b' of the clamping spring 5' has a plug-in or joining end 40 at its free end, which engages the recess 39 of the housing element 13' via the opening 37 of the functional element 23' and the opening 28 of the busbar 4'. The contact leg 5b' of the clamping spring 5' is thus located outside the through-hole 10' and is positioned or supported on the busbar 4' or on the functional element 23', as well as in or on the housing element 13'.

[0060] When executing according to the Fig. From 19 to 25, the (insulating) housing 2'' of the conductor terminal 1'' again features a busbar 4'' and a clamping spring 5'' with a contact leg 5b'' and a spring arc 5c'' as well as a clamping leg 5a'', the clamping edge 16'' of which in turn forms a clamping point 6'' for the electrical conductor 3''. In this design, the conductor terminal 1'' is particularly narrow or has a small size or dimensions.

[0061] The in Fig. The busbar 4'' shown separately in Figure 23 has a through-opening or passage opening 10''. In the area of ​​the through-opening or passage opening 10'', particularly at its narrow end, the busbar 4'' has a wall or collar section 17'' as a clamping point 6'' for the clamping spring 5'', and opposite it, a wall or collar section 25''. In the area of ​​this wall or collar section 25'', the busbar 4'' has a through-opening or passage opening 38', preferably between opposing recesses 41 for the rocker arm 14'' or for its bearing leg 14c''.

[0062] A wall element 11 arranged in the conductor insertion direction L behind the feedthrough or passage opening 10'' is in turn preferably a component of a Fig. 25 shown, a cap- or lid-like housing part or housing element 13'' is inserted or can be inserted into the (insulating material) housing 2''. The housing element 13'' in turn has a joining pin 36' with a recess or groove 39'.

[0063] A in Fig. 24. A comparatively clearly recognizable rocker arm as a pivoting element 14'' for opening the clamping of the clamping leg 5a'' at the clamping point 6'' or at the wall or collar section 17' is mechanically coupled to the clamping leg 5a'' of the clamping spring 5''. The rocker arm 14'' in turn has a lever section 14a'' coupled to a push button 15'' and a contact leg 14b'' bearing against the clamping leg 5a'' as well as a bearing leg 14c'', preferably again two parallel bearing legs 14c''.

[0064] Each bearing leg 14c'' interacts on one side with a bearing contour 18'' of the wall element 11'' and on the other side with a bearing contour 34' of a functional element 23'', forming a bearing or a counter-bearing for the rocker arm 14''. The bearing leg 14c'' has a disc-like bearing contour 20'' which lies in a bearing contour 18'' of the wall element 11'', preferably a shell-like one. The bearing leg 14c'' has a bearing section 21'', in particular mushroom-head-shaped, which lies in a corresponding bearing contour 34' of the functional element 23''.

[0065] In the Fig. 21 and Fig. Figure 22 shows the functional element 23'' and the clamping spring 5'' engaged with the functional element 23''. The functional element 23'' has – analogous to the embodiment according to Fig. 17 - a detent section 23a'' for forming a releasable detent connection 22'' with the clamping leg 5a'' of the clamping spring 5''. The functional element 23'' has a contact section 23f'' for contact with the busbar 4'' and a release section 23b'' that can be actuated by the conductor 3'' under pressure to release the detent connection 22''. The release section 23b'' is connected via a bend 23c'', preferably corresponding to that of the Fig. 6 and / or 15, connected to rest section 23a''.

[0066] The functional element 23'' has a bearing or functional section 23h' for supporting the pivoting element or rocker arm 14''. The bearing or functional section 23h' is formed on or by at least one bearing leg 42, preferably two parallel bearing legs 42. Each bearing leg 42 extends laterally to the passage opening 10''. In particular, the parallel bearing legs 42 extend on both sides of the passage opening 10''. A contact edge 43 is formed between the bearing legs 42, or extending transversely to each bearing leg 42. The contact section 23f'' of the functional element 23'' rests against the outer side of the wall or collar section 25'' via this contact edge. In other words, the functional element 23'' is supported on the busbar 4'' by the contact edge 43.

[0067] The respective bearing leg 42 extends towards the narrow-sided wall or collar section 17'', or towards the clamping edge 16'' or the clamping point 6'' when the clamping leg 5a'' is not engaged, or in its clamping position on the wall or collar section 17''. In other words, the respective bearing leg 42 runs longitudinally along the busbar 4'', or parallel to the distance or an imaginary distance line between the wall or collar sections 25'' and 17''. The respective bearing leg 42, which is suitably bent at its free end, forms the bearing contour 34' of the functional element 23'' as a counter bearing for the rocker arm 14'' mounted in the wall-side bearing contour 18''.

[0068] With a view also to the Fig. Figure 24 shows that, in the through-opening 10'' designed as a through-pass, the bearing legs 42 of the functional element 23'' extend on both sides of a respective longitudinal wall 44 of the through-pass. The respective bearing point of the bearing section 21'' of the rocker arm 14'' is located on the rear side of the busbar 4'', advantageously directly below the contact point of the contact leg 14b'' of the rocker arm 14'' on the clamping leg 5a'' of the clamping spring 5''.

[0069] The conductor terminal 1'' is particularly narrow due to the bearing legs 42, which run laterally to the through-opening 10'' or the through-opening and extend along a part or section of the length of the through-opening 10'' or the through-opening 4'' oriented in the longitudinal direction of the busbar 4''. The conductor terminal 1'' thus has particularly small dimensions, especially in the longitudinal direction of the busbar 4''.

[0070] The bearing or functional section 23h' of the functional element 23'' has an opening 35' on a section opposite the mounting section 23f''. When the functional element 23'' is inserted into the housing element 13'', an insertion pin 36' of the housing element 13'' engages through the opening 35' of the functional element 23''. The mounting leg 5b'' of the clamping spring 5'' has a plug-in or joining end 40', which is located in the Fig. 20 and Fig. 22 shows the assembly state of the clamping spring 5'' with the functional element 23'' in the through-hole 38' of the busbar 4''.

[0071] The functional element 23'' has a insertion or through-hole 37' in the installation section 23f'', which aligns with the through-hole 38' of the busbar 4''. The joining pin 36' of the housing element 13'' has a recess or groove 39', which in turn aligns with the openings 37', 38'. With the insertion or joining end 40' extending through the aligned openings 37', 38', the contact leg 5b'' of the clamping spring 5'' sits in the recess 39' of the housing element 13' in the assembled state. The contact leg 5b'' of the clamping spring 5'' is thus again arranged outside the through-hole 10'' and supported on the busbar 4'' or on the functional element 23'' as well as in the housing element 13''. The bearing point or counter bearing is positioned between the rocker arm 14'' and the functional element 23'' outside the passage or through-opening 10'' between its narrow-sided wall or collar sections 17'' and 25''.
