[0004] The connection terminal for electrical devices described in EP 0 212 330 A2 is a connection terminal with an insulating body and conductor connection contacts arranged therein, at least one of which is a protective conductor contact provided with an additional contact part which passes through the wall of the insulating body facing a terminal carrier and can be contacted with the terminal carrier, wherein the additional contact part forms an external plug for direct contact engagement in an insertion opening of the terminal carrier.

[0005] EP 1 045 475 B1 discloses a screwless connecting terminal for electrical conductors. This terminal comprises a contact frame having a U-shaped profile with a U-shaped web and U-shaped legs aligned parallel to one another. Furthermore, this terminal comprises a clamping spring that interacts with the contact frame and has a clamping spring web and spring legs. The clamping spring web is connected to the U-shaped profile of the contact frame, and the spring legs rest with their clamping edges against abutments of the contact frame. The U-shaped legs of the U-shaped profile of the contact frame have projections extending beyond the U-shaped web of the U-shaped profile, which are deformed outward and form the abutments of the contact frame intended for the contact of the clamping edges of the spring legs.

[0006] DE 199 49 387 A1 discloses a terminal for electrically connecting at least one electrical contact element to a conductor wire, comprising an insulating body in which the contact element is arranged, wherein at least one insertion hole for the conductor wire is arranged upstream of the contact element in the insulating body in an insertion direction, and wherein the contact element is electrically connected to a contact part that extends outward through a receiving hole in a wall of the insulating body. To ensure simple assembly and secure positioning, the contact part is inserted into the receiving hole from the inside and secured against inward displacement by the contact element. For this purpose, the contact element and the contact part can be connected to one another by a Scheid clamp contact.

[0007] The invention is based on the object of designing a connecting terminal such that the connecting terminal has a smaller design, especially when multiple terminal points for the conductors are to be provided per chamber, i.e., it is to be very space-saving. It is also intended to enable improved and simplified assembly of the contact part in the contact frame, while ensuring reliable contact. Furthermore, due to the design of the contact body, comprising a spring element and a contact frame and / or a push-button on the insulating body, the terminal points should not interfere with each other.

[0008] The objects are achieved according to the invention by the features specified in independent claim 1. The dependent claims define advantageous or preferred embodiments of the invention.

[0009] The connection or connecting terminal for electrical conductors, for electrically connecting at least one conductor and at least one electrical contact body, has an insulating body in which the contact body is arranged, wherein the contact body has at least one contact frame and a spring element cooperating with the contact frame, wherein the contact frame is provided with at least one web with adjoining legs, wherein the spring element has an arm and wherein spring legs are arranged directly or indirectly at the end of the arm.

[0010] An advantageous feature of the connection or connecting terminal is that an upper contact frame web and a lower contact frame web can be provided on the contact frame, which can be arranged offset from one another and can be connected via an offset web.

[0011] For this purpose, the arm of the spring element can be arranged transversely and rest on the offset web. Additionally, the arm of the spring element can be held in its vertical position by at least one guide element or, alternatively, between guide elements.

[0012] It is also advantageous that two of the spring legs can be bent at a different level than the other two spring legs, and that each pair of spring legs can be bent on opposite sides of the arm.

[0013] Preferably, the spring element can be formed in one piece.

[0014] For this purpose, the spring element can be arranged within the contact frame.

[0015] It is preferred that each pair of spring legs can be arranged via a spring leg connection at the respective ends of the arm of the spring element.

[0016] The spring element can be held laterally by positioning legs of the contact frame.

[0017] In addition, the spring legs of the spring element can rest with their free ends on contact points of the contact frame.

[0018] Furthermore, the connection or connecting terminal for electrical conductors, for electrically connecting at least one conductor and an electrical contact body, can have an insulating body in which the contact body is arranged, wherein the contact body has at least one contact frame and a spring element cooperating with the contact frame, wherein the contact frame is provided with at least one web with adjoining legs, wherein a contact part is provided which passes through the insulating body and / or a fixing element below the insulating body and can be contacted with the contact frame.

[0019] An advantageous feature is that a tongue of the contact part can be held and / or contacted between a web of the contact frame and a tab of the contact frame.

[0020] A further advantageous feature is that a tongue of the contact part protrudes through an opening in the contact frame, wherein at least one locking element can be provided on the tongue of the contact part and can be engaged with the contact frame. A reverse arrangement cannot be ruled out, wherein at least one locking element is provided on the contact frame and / or on the spring element and is engaged with the tongue of the contact part. In this case, the locking element can preferably be arranged on the arm of the spring element and can be engaged in a recess in the tongue of the contact part.

[0021] A springy tab is preferred.

[0022] It is also preferred that the tab can be arranged on the upper contact frame web of the contact frame, extends downwards and can form approximately a plane with the upper contact frame web.

[0023] Furthermore, the connection or connecting terminal for electrical conductors, for electrically connecting at least one conductor and an electrical contact body, has an insulating body in which the contact body is arranged, wherein the contact body has at least one contact frame and a spring element cooperating with the contact frame.

[0024] An advantageous feature is that the pusher can be designed flexibly around its center line.

[0025] The handle can be positively connected to at least one connecting element around an axis of the insulating body.

[0026] It is preferred that the push button has buttons that can be connected to one another via at least one connecting tongue and / or at least one connecting tab.

[0027] It is advantageous if each button of the pusher can be pivoted without affecting the other buttons of the pusher and can act on the spring leg arranged below it.

[0028] Preferably, the individual buttons of the push-button can be individually flexible. The individual buttons of the push-button are flexibly connected by a connecting element. The connecting element preloads the push-button. Due to its preload, the connecting element allows the buttons to be reset.

[0029] The buttons of the push-button can preferably be designed to be self-resetting. The spring-back action can be achieved at least by means of the connecting element. A return spring, a separate element from the button that would act on this button, can thus be omitted. The design of the push-button is advantageously simplified in this case.

[0030] A connection or connecting terminal for electrical conductors is also provided, for electrically connecting at least one conductor and an electrical contact body, with an insulating body in which the contact body is arranged, wherein insertion holes are provided in the insulating body, wherein a plurality of insertion holes are present in a row, and wherein electrical conductors can be inserted into the insertion holes.

[0031] A mortise hole can be offset by a certain distance from the mortise hole adjacent to it on a horizontal row.

[0032] For this purpose, the insertion holes of a horizontal row can be offset from the insertion holes of the adjacent vertical row.

[0033] It is advantageous if the design of the connecting terminal can be very low in height. The inventive design of the contact frame and the spring element allows the connecting terminal to be very low.

[0034] The respective pushbutton for each connection pole for the connection or connecting terminal can be designed as a single piece, while each button still remains independent. The pushbutton can advantageously be designed very low.

[0035] By combining the advantages of the contact frame, spring element and push button, the height of the connection or connecting terminal can be reduced.

[0036] The conductors are released via connected rotating mechanisms that are arranged at a 90° angle to the connection or connecting terminal.

[0037] The connection terminal according to the invention can be used, for example, as a lighting connection terminal. Due to its small and low design in height and width, it can also be used in LED applications.

[0038] The connection or connecting terminal according to the invention can preferably be a screwless connection or connecting terminal.

[0039] A luminaire with the connection or connecting terminal according to the invention is also disclosed.

[0040] In the following, the invention is described in more detail using embodiments which, however, are to be understood only as examples and not as limiting.

[0041] It shows: Fig. 1 and Fig. 2: a perspective view of a connecting terminal according to the invention; Fig. 3: an exploded view of a connection or connecting terminal according to the invention, with all contact frames and spring elements; Fig. 4: a further exploded view of a connection or connecting terminal according to the invention, with all contact frames and spring elements; Fig. 5: a perspective view of a connection or connecting terminal according to the invention with an actuation possibility; Fig. 6: further views of a connecting terminal according to the invention; Fig. 7: a perspective view of a connecting terminal according to the invention before assembly; Fig. 8: a perspective view of a connecting terminal according to the invention after assembly; Fig. 9: further views of a contact body according to the invention after assembly; Fig. 10A: a perspective view of a contact body according to the invention with a variant of the contact part; Fig. 10B: a further perspective view of a contact body according to the invention with a variant of the contact part; Fig. 11: a rear view of a contact body according to the invention with a variant of the contact part; Fig. 12: a front view of a contact body according to the invention with a variant of the contact part; Fig. 13: a side view of a contact body according to the invention with a variant of the contact part; and Fig. 14: several views of the contact part.

[0042] In Fig. 1 and in Fig. Figure 2 shows exemplary embodiments of the connection or connecting terminal 1 according to the invention, advantageously as a screwless connection or connecting terminal. The connection or connecting terminal 1 has an insulating body 2. Several push-buttons 3 are arranged in the insulating body 2. A fixing element 6 is provided on the underside of the insulating body 2.

[0043] In Fig. 3 and in Fig. 4 shows further views of the connection or connecting terminal 1 according to the invention.

[0044] The pushbutton 3 can be arranged radially within the insulating body 2 via a swivel joint. The pushbutton 3 can be covered by a cover 70. The cover 70 can form the upper part of the insulating body 2. The pushbutton 3 is designed such that two connection poles can be actuated at a time. This enables faster assembly than if one pushbutton is used for two connection poles. This prevents incorrect assembly.

[0045] The lower part 71 of the insulating body 2 has several chambers that are separated from each other. An electrically conductive contact body is positioned in each inner chamber of the insulating body 2. This contact body consists of at least a contact frame 4 and a spring element 5. The electrical connection or electrical contacting between the Fig. 1 and Fig. 2 conductors 8, not shown, which can be inserted into the respective insertion holes 9, 10, 11, 12.

[0046] The structure of the contact body will be explained later in the description.

[0047] The push button 3 has buttons 17. To ensure the required pivoting capability of the buttons 17, the push button 3 is positively connected to the insulating body. The two buttons 17 are connected via the connecting element 16 of the push button 3. The connecting element 16 can preferably be elongated and can serve to reset the buttons 17. A pivot joint 73 is provided for each button 17.

[0048] To ensure access of the button 17 to the contact body or spring element 5, a button tongue 18 is provided at the end of each button 17. By rotating the button 17 in direction D1, the button 17 will open the respective terminal point when the conductor is inserted, in order to remove the conductor, as shown in Fig. 6, whereby the conductor can be removed in direction D2. Upon release by turning in direction D1, the button 17 of the pusher 3 springs back to its original position. The individual buttons 17 of the pusher 3 are self-resetting due to the tension exerted on them by the connecting element 16. The design of the button cable 18 can preferably be selected such that it rests in the actuating opening 74 of the upper part 70 in the resting or tension-free state.

[0049] In Fig. 5 shows a possibility of how the rotation of the key tongue 18 of the key 17 in the direction D1 can be carried out, for example with a tool 13. Here, however, the tool 13 is only used for rotation; no special or defined tool is required.

[0050] The buttons 17 of the push button 3 can be pivoted and rotated independently of each other.

[0051] There may also be known test holes on the upper part 70 and / or lower part 71 to allow access to the contact body in a chamber of the insulating body 2 in order to test the electrical contact.

[0052] The handle is made of an insulating material, such as a thermoplastic.

[0053] The Fig. Figure 8 shows a perspective view of a connection or connecting terminal 1 according to the invention. The connection or connecting terminal 1 according to the invention can be mounted on a light panel 75, preferably by inserting the fixing element 6 into a fastening opening of the light panel 75 and securing it there by means of a clamp. For this purpose, the fixing element 6 can have a fixing lug 76, which can be spring-loaded and can be displaced in the fastening opening to secure the connection or connecting terminal 1.

[0054] The connection or connecting terminal 1 is contacted or locked into place by sliding it onto the grounding (contact part 7). The contact legs 78 of contact part 7, arranged at a 90° angle on both sides, serve to achieve the standard pull-out force.

[0055] Poles or insertion holes 9 and 10 belong together, and on the opposite side, poles or insertion holes 11 and 12 may also be present, which also belong together. These are the poles or insertion holes of one contact chamber. Furthermore, the insertion holes belong together; they are the poles or insertion holes of another contact chamber. This also applies to the other insertion holes in group 9 / 10 / 11 / 12.

[0056] To facilitate handling and as an additional insertion aid for the conductors 8 into the insertion holes 10, 12 located in the lower tier, the insertion holes 10, 12 of the lower tier are beveled at an angle in the insulating body 2 so that the conductors 8 can be better positioned from above into the insertion holes 10, 12. The insertion holes 9, 11 can also be beveled as an insertion aid. The insertion holes 9, 10, 11, 12 can also be rounded.

[0057] The bevel of the insertion holes 9, 10, 11, 12 as well as the offset between the insertion holes within a row acts as an insertion funnel for the conductors 8. This can make it easier for the fitter or electrician to visually align the insertion holes 9, 10, 11, 12 with the conductors 8.

[0058] In the insertion holes 9, 11 of the insulating body 2, conductors 8 of all types can be used, such as single-wire, multi-wire, flexible, or rigid conductors, since the spring leg behind each insertion hole 9, 11 can be controlled by a button 17. This means that the conductors 8 can be inserted or pushed in or unplugged or pulled out without having to exert pressure on the conductor itself.

[0059] The connection or connecting terminal 1 can be attached to other elements via the fixing element 6. It can be mounted, for example, on a sheet metal, a luminaire housing, or parts of a lighting device.

[0060] This can preferably be done without tools by snapping the fixing lug 76 into place, for example as a snap.

[0061] In Fig. 3 and Fig. Figure 4 shows a chamber of the lower part of the insulating body and illustrates the structural relationship between the contact frame 4, the spring element 5 and the contact part 7. From this, the assembly of these elements can be derived.

[0062] The contact frame 4 and the spring element 5 form a structural unit as a contact body, which is preferably prefabricated and can be inserted as a structural unit through a chamber opening of the insulating body 2, which in the embodiments shown here can be located below the insulating body 2.

[0063] In the present terminal 1, the insulating body 2 consists of several separate chambers. A contact body can be arranged in each chamber. For each chamber, there are insertion holes 9, 10, 11, 12 in the insulating body 2, which are arranged one above the other or opposite each other. This provides four main terminal points per chamber.

[0064] The terminal according to the invention thus enables the conductors to be fed in from several different directions.

[0065] In the Fig. 3 and Fig. 4 and 10-13 show, among other things, the contact body. The contact body consists of at least a contact frame 4 and a spring element 5. There is one contact body per chamber in the insulating body. Since there are two rows of insertion holes 9 and 11 or 10 and 12 per side in the insulating body 2, an upper and a lower row, the spring element 5 should be designed for two conductors 8 per side. In this case, the spring element 5 can have two levels. If necessary, the contact frame 4, which represents a holder for the spring element 5, can be designed with two levels.

[0066] According to the invention, the contact frame 4 has an upper contact frame web 30 and a lower contact frame web 31, which are oriented edgewise. These two contact frame webs 30, 31 can be offset if an offset web 32 is present transversely to the contact frame webs 30, 31 and connects these contact frame webs 30, 31. Furthermore, the contact frame 4 has legs 33, 34, which are arranged adjacent to the upper and lower contact frame webs 30, 31, respectively. These legs 33, 34 can be arranged perpendicular or approximately perpendicular to the upper and lower contact frame webs 30, 31. Due to the offset web 32, the contact frame 4 does not form a conventional C-shape, but rather the edgewise C-leg has an offset. This offset does not necessarily have to be present in the center of the edgewise C-leg.

[0067] The spring leg 5 is preferably formed in one piece. It has an arm 27 that extends transversely along the upright contact frame webs 30, 31 in the assembled state. The arm 27 preferably rests on the offset web 32 of the contact frame 4 in the assembled state and is guided or held by guide elements on the contact frame 4. Guide elements 41, 42 may be provided, arranged above the offset web 32, so that the arm 27 of the spring element 5 can be positioned between the offset web 32 and the guide elements 41, 42. If no offset web 32 is present or if the width of the offset web 32 is insufficient, additional guide elements 43, 44 may be provided, on which the arm 27 of the spring element 5 can rest. The guide elements 41, 42, 43, 44 can, for example, be punched as tabs from the upper or lower contact frame web 30, 31 of the contact frame 4.

[0068] At the ends of the arm 27, the spring legs 23, 25 are each connected to the arm 27 via a bent edge as a spring leg connection 28, 29 and are bent and inclined by the latter. The lower spring legs 24, 26 can be punched from the arm 27 of the spring element 5. As a result, the lower spring legs 24, 26 can not be as wide as the upper spring legs 23, 25. It is advantageous if the upper spring legs 23, 25 are wide so that the button 18 of the push button 3 can have a better pressure surface. The lower spring legs 24, 26 can be bent and inclined by the respective spring leg connections 28, 29. The free ends of the spring legs 23, 24, 25, 26 can be directed towards the legs 33, 34 of the contact frame 2. The upper part of the spring element 5 with the arm 27 and the upper spring legs 23, 25 is a further development of known spring elements for connection and connecting terminals.The lower part with the lower spring legs 24, 26, which are formed integrally with the upper part of the spring element and, for example, stamped from the arm 27 of the spring element 5, is a feature of the invention. This enables a connection and connecting terminal 1 with two rows of connection poles per side, which remains compact and is advantageous for LED applications due to its smaller design. The spring legs 23, 24, 25, 26 are arranged on two levels.

[0069] Positioning legs 35, 36 are provided on the side of the contact frame 4. When mounting the spring element 5 on the contact frame 4, they enable lateral support or locking of the spring element 5. The positioning legs 35, 36 can also be provided as supports. They are preferably arranged within the spring leg connections 28, 29 and are designed, for example, as tabs.

[0070] It would also be conceivable to have two separate spring elements, in which case arm 27 would be omitted. One spring element could have spring legs 23 and 25, which would be connected via spring leg connection 28. The other spring element could have spring legs 24 and 26, which would be connected via spring leg connection 29.

[0071] Contact points 37, 38, 39, 40 are provided on the legs 33, 34. The free ends of the spring legs 23, 24, 25, 26 are held by the respective contact points 37, 38, 39, 40 or are supported on these contact points 37, 38, 39, 40. The contact points can be knob-like, such as contact points 39 and 40 here. They can also be formed as stamped tabs from the leg of the contact frame 4, such as contact points 37 and 38 here. Each spring leg 23, 24, 25, 26 can thus exert its spring forces independently of the other spring legs.

[0072] It is also advantageous to provide stops 57, 58 which can limit the insertion depth of the associated conductor. The stops 57, 58 are each formed by a one-piece bend on the contact frame 4. Here, the tab 57 forms a stop for the conductors which are inserted in the upper level, i.e. into the insertion holes 9 and 11. The tab 58 forms on one of its sides the stop for the conductor which is inserted into the insertion hole 10, and on its other side the stop for the conductor which is inserted into the insertion hole 12. The conductors 8 do not necessarily have to be inserted up to the stop 57, 58, e.g. if they were a little shorter.

[0073] Tabs 55 and 56 are guide elements for the ladder on the upper level. They serve as mechanical ladder guidance and support.

[0074] Recesses can be provided in the insulating body 2 to enable a holding or snap-in function for the guide elements 55 and 56 so that the contact frame 4 can be held in the insulating body 2.

[0075] The spring element can advantageously be manufactured from a strip-shaped material blank. The spring element consists of a material with spring properties and temperature resistance.

[0076] The contact frame 4 and spring element 5 are metal parts that can have different electrical conductivities.

[0077] In the central region of the arm 27 of the spring element, the latter has a free space or a recess or an offset in order to create space for the contact part 7.

[0078] A contact part 7 can be inserted into the connection or connecting terminal 1. The contact part engages through the fixing element 6 and the insulating body 2 and comes into contact with the contact body, here with the contact frame 4. This can be seen, for example, in Fig. 7. A recess may be provided in the fixing element 6 and in the insulating body 2 so that the contact part 7 can be inserted into the connection or connecting terminal 1.

[0079] A tab 45 can be provided on the contact frame 4, which is designed to be resilient. This tab 45 can be punched out of the contact frame 4 and shaped accordingly. For example, in the illustrated embodiment, the tab 45 is arranged below the upper contact frame web 30. Due to its resilient nature, the contact part 7, which can be inserted between the lower contact frame web 31 and the tab 45, is clamped. It is important that the contact part 7 can be fixed in or on the contact frame 4.

[0080] In addition, a locking or latching contact can be provided between the contact frame 4 and the contact part 7. Various designs for the locking or latching contact can be provided. In the present embodiments, either a latching element 50 ( Fig. 10A) or locking knobs ( Fig. 12) on contact part 7. Other possibilities, such as locking hooks, are not excluded. A corresponding counterpart, such as a locking edge 47, is provided on contact frame 4, preferably on the lower contact frame web 31, which forms a stop for locking element 50.

[0081] The offset 32 between the upper contact frame web 30 and the lower contact frame web 31 is advantageous to allow space for the contact part 7. The offset 32 is also intended to prevent the conductors 8 and the contact part 7 from coming into direct contact with each other.

[0082] During assembly, the contact body can first be positioned in the insulating body 2, and then the contact part 7 can be inserted from the outside through the insulating body 2 or the fixing element 6, where it automatically locks into place. This can be achieved by a positive or non-positive locking mechanism.

[0083] The lower part of the contact part 7 can have various embodiments.

[0084] The lower part of the contact part (for example in Fig. 10 to 13) can have sharp lateral edges so that the coating can be removed from another element during contacting and the desired contact can be made.

[0085] Contact part 7 is preferably a ground connection. In this case, it can form a ground contact. In this case, a good and trouble-free connection between contact frame 4 and contact part 7 is required to avoid compromising grounding safety in the event of a lack of electrical contact.

[0086] Contact part 7 is a stamped and bent part that can be easily and quickly punched out of a circuit board.

[0087] The connection or connecting terminal 1 according to the invention enables a very flat design. This flat design is possible on both sides and allows for integrated direct grounding (PIEC). Grounding is established directly upon insertion of the connecting terminal into the T-hole cutout. Grounding via contact part 7 is achieved laterally via the material thickness or with two sharp points 77 at the 90° bend of the two contact legs 78 of contact part 7 (so that the paint is scraped off when inserting the connecting terminal).
