Summary of the Invention

Problems to be Solved by the Invention

[0003] The underlying problem of the present invention is to present a miniaturized conductor connection terminal, especially for conductors with a very small cross-section.

Means for Solving the Problems

[0004] In the case of a conductor connection terminal of the kind mentioned at the beginning, this problem is solved in that the housing has a first receiving contour on its outer surface, and in this first receiving contour, a rotatable operating lever adapted to manually operate the first clamping spring can be engaged with the housing. The conductor connection terminal according to the present invention can provide a spring-type terminal system with a very small structure for very small conductors, and in addition, due to the first receiving contour, there is a possibility of engaging a rotatable operating lever for operating the first clamping spring with the housing. This operating lever enables intuitive operation of the conductor connection terminal by the user.

[0005] This operating lever can be engaged with the housing only when necessary, and in some cases can be removed from the housing again after use. Accordingly, no permanent area is required for the operating lever. This is also favorable for miniaturizing the terminal system. The operating lever can be fixed to the housing of the conductor connection terminal by engaging with a first housing contour, and in this regard, the pivoting motion necessary for the operation of the first clamp spring is possible.

[0006] According to an advantageous embodiment of the present invention, the actuating lever is intended to be pivotably supported in the first housing contour when it is engaged with the first housing contour. For example, the first housing contour itself, together with the mounting contour of the actuating lever engaged therewith, can constitute a swivel bearing, which in turn forms a swivel axis for the rotation of the actuating lever. Alternatively or in addition, the actuating lever may have sufficient elasticity to perform the desired swivel motion. In this case, the actuating lever in the first housing contour can be fixed in place, at least insofar as no swivel motion occurs therewith.

[0007] In one advantageous embodiment of the present invention, the housing has a first conductor insertion opening on the first conductor insertion side, through which a first conductor can be inserted into a first clamping area formed by a first clamping spring for clamping the first conductor, and the first housing contour is intended to be located on the side of the housing opposite to the first conductor insertion side. In this case, at least the portion of the first clamping spring to which force is applied by a pivotable operating lever during manual operation can be located on the side of the housing toward the first conductor insertion opening, or at least closer to the first conductor insertion opening than the first housing contour. Thus, in this case, the operating lever covers the main portion of the housing, particularly the main portion in the longitudinal direction of the housing. In this way, a large lever arm length can be achieved even in a very miniaturized conductor connector with a relatively small housing, which is favorable for the simple and ergonomic operation of the first clamping spring.

[0008] In an advantageous embodiment of the present invention, the housing has a first operating opening in the region of the first clamp spring, and it is intended that the first clamp spring can be actuated by the pivoting motion of an operating lever engaged with a first housing contour. The first operating opening may be located in the housing, in particular, on a side of the housing different from the first conductor insertion side, for example, on a side of the housing that is substantially perpendicular to the first conductor insertion side. The first operating opening may be formed as a relatively small opening, so that conductive components located within the housing are well protected from ambient influences.

[0009] According to an advantageous embodiment of the present invention, the conductor connection terminal has a second spring clamp connection portion within the housing, the second spring clamp connection portion having a second clamp spring for clamping a second conductor by spring force, the housing has a second conductor insertion opening on the second conductor insertion side, the second conductor can be inserted through this second conductor insertion opening into a second clamping location formed by the second clamp spring for clamping the second conductor, and this second conductor insertion side is intended to be the housing side opposite to the first conductor insertion side. This is particularly advantageous as it enables the realization of a very miniaturized connector terminal in the sense of a pass-through terminal, in which the conductor is inserted on the opposing housing side. The housing may have a second operating opening in the region of the second clamp spring following the first operating opening, and this second operating opening allows the second clamp spring to be actuated by the pivoting motion of an operating lever engaged with a second housing contour. The second operating port may be located in the housing, in particular on a different side of the housing from the second conductor insertion side, for example, on a side of the housing that is substantially perpendicular to the second conductor insertion side. In particular, the first and second operating ports may be located on the same side of the housing. The second operating port may be formed as a relatively small opening, which provides good protection for conductive components located within the housing from ambient influences.

[0010] According to an advantageous embodiment of the present invention, the housing has a first accommodating contour on the second conductor insertion side and a second accommodating contour on the first conductor insertion side for engagement of the operating lever, and therefore a) The same operating lever can selectively engage with the first or second housing contour, or b) It is intended that a first operating lever can be engaged with a first housing contour and / or a second operating lever can be engaged with a second housing contour.

[0011] As a result, the conductor connection terminal according to the present invention can be used particularly in a general-purpose manner. The first spring clamp connection may have a first power rail section in addition to the first clamp spring. In this case, the clamping location for clamping the conductor is formed between the first power rail section and the first clamp spring, particularly the clamping edge of the first clamp spring. If the conductor connection terminal has the second spring clamp connection mentioned, this second spring clamp connection may have a second power rail section in addition to the second clamp spring. In this case, the second clamping location for clamping the second conductor is formed between the second power rail section and the second clamp spring, particularly the clamping edge of the second clamp spring. In one advantageous embodiment of the present invention, the first power rail section is electrically coupled with the second power rail section. In particular, the first power rail section together with the second power rail section can form a common continuous power rail, that is, it can be formed as a continuous metal section.

[0012] According to an advantageous embodiment of the present invention, the first housing contour is intended to extend across the entire width of the housing. This allows the operating lever engaged with the first housing contour to be displaced in the width direction of the housing, for example, from one spring clamp connection to the next, or from one housing to the next if multiple housings are connected in the width direction. The width direction of the housing, in which the housing width can be measured, is in particular the spatial direction parallel to the pivot axis of the operating lever.

[0013] According to an advantageous embodiment of the present invention, the conductor connection terminal has a plurality of first spring clamp connections arranged side by side within a housing, into which one first conductor can be inserted through a first conductor insertion opening assigned to each of the first spring clamp connections, and these first conductor insertion openings are intended to be located on the same first conductor insertion side of the housing. This makes the conductor connection terminal suitable for connecting multiple conductors. These first spring clamp connections may be electrically isolated from each other, or they may be electrically coupled to each other partially or entirely.

[0014] If the conductor connection terminal is formed as a through terminal with a second spring clamp connection as described above, the conductor connection terminal may have a second spring clamp connection allocated to each of the first spring clamp connections.

[0015] The housing of the conductor connection terminal can be a continuous housing in the direction of alignment, and this housing accommodates multiple or all of the first spring clamp connectors, and possibly also accommodates a second spring clamp connector. The conductor connection terminal can also be formed as a modularly assembleable terminal block, in which case multiple housing modules are arranged in a slice-like fashion in the direction of alignment and connected to one another. Such a housing module may, in this case, accommodate, for example, one first spring clamp connector, or in the case of a through terminal, one first and one second spring clamp connector.

[0016] In an advantageous embodiment of the present invention, the housing has one first housing contour assigned to one of the first spring clamp connections, and these first housing contours are arranged collinearly (in other words, flush with each other) on the same side of the housing, so that one operating lever engaged with one first housing contour is displaceable in the parallel direction from one first housing contour to another. In this way, multiple or all of these first spring clamp connections can be operated by one same operating lever. This eliminates the need for a separate operating lever for each first spring clamp connection.

[0017] Accordingly, the housing may have one second housing contour assigned to each of the second spring clamp connections, and these second housing contours are collinear with each other on the same side of the housing, so that one operating lever engaged with one second housing contour can be displaced in the parallel direction from one second housing contour to another. In this way, multiple or all of these second spring clamp connections can be operated by one same operating lever. This eliminates the need for a separate operating lever for each second spring clamp connection.

[0018] According to an advantageous embodiment of the present invention, the housing has a retaining contour for attaching a fixing flange to the housing, and the housing is intended to be fixed to another article by this fixing flange. This has the advantage that the conductor connection terminals can be easily fixed to another article, for example, a mounting socket, mounting plate, or other article. The fixing flange can be fixed to the housing or retaining contour by engagement using, for example, one or more engaging elements.

[0019] According to an advantageous embodiment of the present invention, the actuating lever is intended to be engageable with a first and / or second housing contour from the outside of the housing. This allows the actuating lever to be easily and intuitively mounted to the housing. Similarly, the actuating lever can be easily removed from the housing again.

[0020] In one advantageous embodiment of the present invention, the first and / or second housing contours are intended to be formed as concave hollow contours. Accordingly, the mounting contour of the operating lever assigned to the first and / or second housing contours may be formed as a convex object. The assignment can also be reversed, that is, the first and / or second housing contours may be convex, and the mounting contour of the operating lever, formed as a concave hollow contour opposite to them, may be formed as a mating member.

[0021] According to an advantageous embodiment of the present invention, the operating lever is intended to be removable from the first or second housing contour without damage when it is engaged with the first or second housing contour. This has the advantage that the operating lever can then be reused, for example, at the same conductor terminal or another conductor terminal.

[0022] In an advantageous embodiment of the present invention, in the first and / or second housing contours, a swivelable actuation lever adapted for manually acting the first clamp spring is engaged with the housing. This actuation lever allows for simple and intuitive operation when opening the clamping portion of the spring clamp connection of the conductor connection terminal.

[0023] According to an advantageous embodiment of the present invention, the first housing contour is positioned between the first conductor insertion opening and the side of the housing where the first operating opening is located. Accordingly, the second housing contour may be positioned between the second conductor insertion opening and the side of the housing where the second operating opening is located.

[0024] The problem mentioned at the beginning is further solved by an operating lever for conductor connection terminals of the type explained above, which has a mounting contour shaped as negative with respect to a first receiving contour, this mounting contour being engageable with the first receiving contour, and furthermore this operating lever has a manual operating surface for manually operating the operating lever. In addition to this, the operating lever may have a protruding operating cam for deflecting a first clamping spring during manual operation of the operating lever. This can also achieve the advantages explained above. The operating lever can be engaged with the first receiving contour by its mounting contour. In this state, in order to open the first clamping point, a force can be applied to and deflected the first clamping spring via the protruding operating cam with the operating lever. Depending on whether the operating lever is accommodated in the first receiving contour or in the second receiving contour, the operating cam can pass through the first or second operating opening of the housing.

[0025] It is advantageous if the operating cam can protrude on the side of the operating lever opposite the manual operating surface. When the operating lever is engaged with the first receiving contour, the operating cam can protrude, inter alia, towards the housing of the conductor connection terminal. Accordingly, the manual operating surface is arranged on the side of the operating lever opposite the housing, whereby the manual operating surface can be easily and comfortably operated manually.

[0026] According to an advantageous form of the invention, it is contemplated that when the operating lever is engaged with the first receiving contour, the mounting contour serves as the pivot axis of the operating lever. Accordingly, the operating lever performs a pivoting movement about the mounting contour. In this case, the operating lever itself does not need to be deformed, especially bent. This enables a tactically favorable and ergonomically based operation.

[0027] According to an advantageous form of the invention, it is contemplated that the operating lever is formed so as not to be substantially bent in the region of its manual operating surface and / or in the region from the operating surface to the mounting contour. Accordingly, this operating lever does not bend substantially during manual operation. The required pivoting movement can be achieved via the pivot axis mentioned above.

[0028] The problem mentioned at the beginning is further solved by a set consisting of at least one conductor connection terminal of the type explained above and at least one actuating lever of the type explained above. By this, the advantages explained above can also be realized.

[0029] In the sense of the present invention, the indefinite concept of "one" must not be understood as a numeral. That is, for example, when referring to one part, this should be interpreted in the sense of "at least one part". When the angular display is made in degrees, this angular display is with respect to the scale of a circle of 360 degrees (360°).

[0030] Hereinafter, the present invention will be explained in more detail with reference to the drawings based on exemplary embodiments.

Embodiments for Carrying Out the Invention

[0032] Figure 1 shows a conductor connection terminal 9 with a housing 3. A first spring clamp connector 1 and a second spring clamp connector 2 are located within the housing 3. The first spring clamp connector 1 has a first clamp spring 10 and a first power transmission rail section 14. The second spring clamp connector 2 has a second clamp spring 20 and a second power transmission rail section 24. The first and second power transmission rail sections 14 and 24 are formed as a common continuous power transmission rail, meaning that the first spring clamp connector 1 is electrically coupled to the second spring clamp connector 2 via this continuous power transmission rail.

[0033] In the illustrated exemplary embodiment, a first clamp spring 10 and a second clamp spring 20 are formed as tension clamp terminals, for example, as cage clamp springs. The first clamp spring 10 is supported on a first power transmission rail section 14 by a contact leg 17. The first clamp spring 10 extends from the first contact leg 17 through a spring arch to a first clamp leg 13, which, together with the first power transmission rail section 14, forms a first clamp location 15 for clamping a first conductor. The first clamp location 15 is located on the side of the first power transmission rail section 14 opposite to the first contact leg 17. The first clamp leg 13 has a first window-like opening 16 through which the first power transmission rail section 14 and / or the first contact leg 17 extend. In this case, when the first clamp spring 10 is mechanically deflected by the actuating element, the first clamp leg 13 moves downward, thereby moving the main part of the first window-shaped opening 16 to the side of the first power transmission rail section 14 opposite to the first contact leg 17. Subsequently, the first conductor can be inserted through this first window-shaped opening 16. When the mechanical force applied to the first clamp spring 10 is removed, the first clamp spring 10 springs back to its original position, thereby firmly clamping the first conductor, which has been inserted through the first window-shaped opening 16, to the first clamp point 15 by the first clamp leg 13.

[0034] The second clamp spring 20 is supported on the second power transmission rail section 24 by a contact leg 27. The second clamp spring 20 extends from the second contact leg 27 through a spring arch to a second clamp leg 23, which, together with the second power transmission rail section 24, forms a second clamping location 25 for clamping the second conductor. The second clamping location 25 is located on the side of the second power transmission rail section 24 opposite to the second contact leg 27. The second clamp leg 23 has a second window-like opening 26 through which the second power transmission rail section 24 and / or the second contact leg 27 extend. In this case, when the second clamp spring 20 is mechanically deflected by the actuating element, the second clamp leg 23 moves downward, thereby moving the main part of the second window-shaped opening 26 to the side of the second power transmission rail section 24 opposite to the second contact leg 27. Subsequently, the second conductor can be inserted through this second window-shaped opening 26. When the mechanical force applied to the second clamp spring 20 is removed, the second clamp spring 20 springs back to its original position, thereby firmly clamping (in other words, fixing) the second conductor, which was inserted through the second window-shaped opening 26, to the second clamp point 25 by the second clamp leg 23.

[0035] The housing 3 has a first conductor insertion opening 33 on the first conductor insertion side 31, through which a first conductor can be inserted into the housing 3 and guided to the first clamping location 15. The housing 3 has a second conductor insertion opening 34 on the second conductor insertion side 32, through which a second conductor can be inserted into the housing 3 and guided to the second clamping location 25.

[0036] On the side of the housing 3 opposite to the first conductor insertion side 31, i.e., the second conductor insertion side 32 in this case, the housing 3 has a first housing contour 11 on its outer surface, to which a swivelable operating lever 5 can be engaged. On the first conductor insertion side 31, the housing 3 has a second housing contour 21 on its outer surface, to which a swivel operating lever 5 can be engaged. As recognized, the first housing contour 11 and / or the second housing contour 21 may extend across the entire width B of the housing.

[0037] The actuating lever 5 has a mounting (in other words, fixing) contour 50 that is molded as a negative to the first housing contour 11, and this mounting contour 50 is engageable with the first housing contour 11. The actuating lever 5 further has a manual actuating surface 51 for manually operating the actuating lever 5, and a protruding actuating cam 52 for deflecting the first or second clamp springs 10, 20 when the actuating lever 5 is manually operated. The actuating cam 52 protrudes from the side of the actuating lever 5 opposite to the manual actuating surface 51.

[0038] The actuation lever 5, when operated manually, can mechanically deflect, for example, the first clamp spring 10, that is, the first clamp leg 13 can move downward as mentioned. For this purpose, the actuation lever 5 can engage with the first housing contour 11 at its mounting contour 50. When pressure is then applied to the manual actuation surface 51 of the actuation lever 5, the actuation cam 52 protruding to the opposite side passes through the first actuation opening 12 of the housing 3 and pushes the clamp leg 13 downward. The actuation lever 5 can also engage with the second housing contour 21 instead. In this case, the second clamp spring 20 can be actuated by the actuation cam 52 in an equivalent manner, the actuation cam 52 protruding in this case through the second actuation opening 22 of the housing 3.

[0039] The conductor connection terminals 9 are formed as terminal modules, and these terminal modules can be modularly assembled into a single terminal block together with further terminal modules of the same structural form. For this purpose, each housing 3 has a protruding insertion pin 35 on one side, which can engage with a recess located on the opposite side of the housing 3.

[0040] Figure 2 shows three conductor connectors 9 of the type shown in Figure 1, engaged with a single terminal block. These conductor connectors 9 are arranged in a row in direction A. The terminal block thus formed includes a cover plate (in other words, a closing plate) 6 at the last conductor connector 9 to cover its exposed housing side, and this cover plate 6 can engage with the plug pins 35 in the same way that the housings 3 engage with each other.

[0041] In addition to the above, Figure 2 shows that the housing 3 and / or the cover plate 6 have a retaining contour 60 for attaching a fixing flange to the housing 3 or the cover plate 6. Figure 3 shows a fixing flange 4 that can be attached to the retaining contour 60. The fixing flange 4 has a retaining element 40, for example in the form of an engaging element, which is molded as a negative contour with respect to the retaining contour 60.

[0042] Figure 4 shows how the type of fixing flange 4 shown in Figure 3 can be fixed to the terminal block based on Figure 2. Furthermore, Figure 4 shows how the operating lever 5 engages with the housing 3, for example, with the first housing contour 11. The operating cam 52 of the operating lever 5 is located in the area of ​​the first operating opening 12.

[0043] Figure 5 shows a terminal block based on Figure 4, in which case the cover plate 6 with a fixed flange 4 has been removed to illustrate the operation of the first clamp spring 10. The operating lever 5 is in the manually operated position here, in which case the operating cam 52 passes through the first operating opening 12, thereby moving the first clamp leg 13 downwards, allowing the conductor to pass through the first window-shaped opening 16. When the operating force on the operating lever 5 is released, the clamp spring 10 springs back to the position shown in Figure 1 and continues to spring back until the conductor to be connected is firmly clamped to the first power transmission rail section 14 at the first clamping point 15, at least partially.

[0044] The conductor connection terminal according to the present invention can be modified in a wide variety of ways. Figure 6 shows one embodiment comprising a housing 3 having two first conductor insertion openings 33 arranged side by side on a first conductor insertion side 31. However, this housing 3 is formed as a continuous housing, that is, it is not composed of two modularly arranged housings as shown in Figure 2. Each of the first conductor insertion openings 33 can be assigned a first spring clamp connection, and these first spring clamp connections can be electrically coupled to each other, for example, by the existence of a continuous first power transmission rail section for both first spring clamp connections. The first spring clamp connections can also be actuated here by an actuating lever 5 engaged with a first housing contour 11. Figure 6 shows one embodiment in which two actuating levers 5 are engaged side by side on the first housing contour 11. One actuating lever 5 is in the manually actuated state, and the other actuating lever 5 is in the deactuated state.

[0045] Figure 7 shows one embodiment in which the conductor connector terminal 9 has only one first conductor insertion opening 33 on the first conductor insertion side 31, to which a first spring clamp connector 1 is assigned, which has a first clamp spring 10 that is considerably wider than the clamp spring clearly shown in the previous figure. This first clamp spring 10 can extend, for example, in the width direction across the width of three first spring clamp connectors in the form clearly shown based on Figure 2, or it can extend across any other number of spring clamp connectors. In this case, the first clamp spring 10, which requires a larger actuation force due to its size, can be actuated by a plurality of actuation levers 5 engaged with the housing 3, for example by three side-by-side actuation levers 5 in the illustrated example. The first clamp spring 10 can be subjected to force either directly by the actuation cam 52 or via a force transmission element 36 positioned between them as shown in Figure 7, which can be formed, for example, as an elastically flexible tongue-shaped portion and can be integrally molded with the material of the housing 3. This equalizes the force transmission to the clamp spring 10 by the three individual actuation levers 5.

[0046] Figure 7 further shows that, on the second conductor insertion side 32, which is directly opposite the first conductor insertion side 31, there are multiple second spring clamp connectors 2, each equipped with one second clamp spring 20 which is smaller than the first clamp spring 10, and in this exemplary embodiment, there are three second clamp springs 20. The second spring clamp connectors 2 are electrically coupled to the first spring clamp connector 1 via a common power transmission rail. In this configuration, the conductor connection terminals 9 can be used in the manner of distribution terminals.

[0047] In extremely miniaturized conductor connectors, instead of operating the spring clamp connector with an operating lever 5, it may be beneficial to use an independent operating element in the form of an operating ring 7, as shown in Figure 8. The operating ring 7 has a ring-shaped portion 70 with an operating cam 71 molded to its outer surface. The operating ring 7 can be worn, for example, on a finger or thumb, and thus can be easily used to operate the spring clamp connector of a miniaturized conductor connector. Figure 9 shows the operating ring 7 as an independent component from another perspective. The ring-shaped portion 70 may, in particular, not be formed as a completely closed ring, but may have a break on one side, for example, on the side opposite to the operating cam 71.
