Description

[0001] This patent application claims the priority of German Patent Application No. 10 2019 126 662.9, the content of which is hereby incorporated by reference in its entirety. Field of the Invention

[0002] The present invention relates to a connection unit having a plurality of connection elements arranged side by side, wherein each connection element has a conductor connection port for receiving an electrical conductor and a manipulation element for clamping and / or releasing the electrical conductor in the conductor connection port, the manipulation element and the conductor connection port being arranged on the same side of the connection unit, and the manipulation elements and the conductor connection ports of the connection elements being arranged in two rows spaced apart from each other by a certain distance.

[0003] Furthermore, the present invention relates to a connection board having a housing and a plurality of connection elements received in the housing, wherein the plurality of connection elements are arranged side by side in the housing, each connection element having a conductor connection port for receiving an electrical conductor and a manipulation element for clamping and / or releasing the electrical conductor in the conductor connection port, the manipulation element and the conductor connection port being arranged on the same side of the housing of the connection board, and the manipulation elements and the conductor connection ports of the connection elements being arranged in two rows spaced apart from each other by a certain distance. Background Art

[0004] Corresponding connection units and connection boards for connecting a plurality of electrical conductors in an efficient manner have been disclosed in the prior art. Among them, a layout in which the manipulation element and the conductor connection port are arranged on one side of the connection unit is widely adopted to achieve simple operation. In addition, by arranging the manipulation element and the conductor connection port in two rows, a connection unit with a smaller size can be provided. On the side where the manipulation element and the conductor connection port are located, the necessary extension of the connection unit is limited to the extension of the manipulation element and the conductor connection port.

[0005] The connection element can be implemented as a spring terminal, for example, and arranged in a common housing. In the case of using spring terminals, the insertion of the electrical conductor automatically causes the electrical conductor to be clamped in the corresponding conductor connection port, and it can be released by operating the attached manipulation element. The connection unit and the connection board can also be implemented for mounting on a printed circuit board, where the pins extend through the printed circuit board and are soldered to the printed circuit board, for example.

[0006] The minimum distance between the connection elements depends on the minimum distance of their conductor connection ports. This minimum distance is determined, for example, by the size of the conductor connection ports and the maximum permitted voltage. A so-called pitch dimension (Rastermaß) is produced, which defines the side-by-side layout of the conductor connection ports and thus also the side-by-side layout of the connection elements. Here, the pitch dimension gives the distance between one point of a connection element and the same point of an adjacent connection element. In the case where the connection elements are arranged side by side closely, the pitch dimension is equal to the width of the connection element.

[0007] The electrical conductor has a conductive wire or stranded wire and has an insulating material wrapped around it. The conductor connection port accommodates the conductive wire or stranded wire such that the insulating material protrudes. In the case of using an electrical conductor with a (particularly with a plastic flange) core wire end sleeve, it may even occur that due to the stretchability of the core wire end sleeve, in particular due to the diameter of the plastic flange of the core wire end sleeve, the conductor connection ports of adjacent connection elements cannot be used simultaneously. As an alternative, in order to be able to use the conductor connection ports of adjacent connection elements simultaneously, the core wire end sleeve can be dispensed with. Therefore, in order to also be able to use electrical conductors with core wire end sleeves, it is necessary to increase the pitch dimension for known connection units. Summary of the Invention

[0008] In view of this, the object of the present invention is to provide a connection unit of the type described at the beginning of this text, which has as compact dimensions as possible and is particularly suitable for using electrical conductors with core wire end sleeves.

[0009] The solution of the present invention to achieve the above object is a connection unit having a plurality of connection elements arranged side by side, wherein each connection element has a conductor connection port for accommodating an electrical conductor and a manipulation element for clamping the electrical conductor in the conductor connection port and / or releasing it, the manipulation element and the conductor connection port are arranged on the same side of the connection unit, the manipulation elements and conductor connection ports of the connection elements are arranged in two rows spaced apart from each other by a certain distance, and the connection unit has at least one first connection element, whose manipulation element is arranged in the first row and whose conductor connection port is arranged in the second row, and has at least one second connection element, whose manipulation element is arranged in the second row and whose conductor connection port is arranged in the first row.

[0010] The solution of the present invention for achieving the above object also lies in a wiring board, which has a housing and a plurality of wiring elements accommodated in the housing. Among them, the plurality of wiring elements are arranged side by side in the housing. Each wiring element has a conductor connection port for accommodating an electric conductor and a manipulation element for clamping and / or releasing the electric conductor in the conductor connection port. The manipulation element and the conductor connection port are arranged on the same side of the housing of the wiring board. The manipulation elements and conductor connection ports of the wiring elements are arranged in two rows spaced apart from each other by a certain distance. And, the wiring board has at least one first wiring element, whose manipulation element is arranged in the first row and whose conductor connection port is arranged in the second row, and has at least one second wiring element, whose manipulation element is arranged in the second row and whose conductor connection port is arranged in the first row.

[0011] The advantage of the wiring unit of the present invention is that through the common layout of the first and second wiring elements, the distance between the conductor connection ports of adjacent first and second wiring elements can be increased, so as to efficiently use the conductor connection ports for connecting electric conductors. When the conductor connection port and the manipulation element are arranged adjacent to each other in one row, there is no need to insert two electric conductors adjacent to each other into the conductor connection port at this place. Different from this, in the prior art, the distance between adjacent conductor connection ports is the distance from one wiring element to the next wiring element. Therefore, according to the present invention, the electric conductor can be reliably positioned in the conductor connection port without being hindered, for example, by the insulation of the electric conductor. Especially when using core wire end sleeves or the like, a sufficient large distance is achieved between the conductor connection ports of adjacent wiring elements, so that the electric conductor with a core wire end sleeve can also be inserted. There is no need to increase the distance between the conductor connection ports. Even each wiring element can be constructed to be particularly narrow, thus providing a particularly compact wiring unit or a particularly compact wiring board. In this case, for example, there is no need to discard the electric conductor with a core wire end sleeve. In this way, the conductor cross-sectional areas that are not supported when only the first or second wiring element is used can also be used. Generally speaking, the insertion or extraction operation of the electric conductor is simplified, thereby improving the operation on the manipulation element and the conductor connection port. The embodiments here and below are applicable to both the wiring unit and the wiring board.

[0012] The technical solution of the present invention for the connection unit and the connection board can simplify the operation because: when the first and second connection elements are arranged adjacent to each other, a free space for the electrical conductor around the insertion conductor connection port is provided by the operating element of the other connection element, so that the electrical conductor can always be well accessed. It can be ensured that the connection element is manipulated by the operating element because the operating element only needs to be accessed when necessary, so as to clamp the electrical conductor and / or cancel the clamping. Therefore, the access can be implemented as needed, and enough space is left between the two electrical conductors, even when the electrical conductor has a core wire end sleeve.

[0013] The electrical conductors can each have a potential. Among them, the electrical conductor can include a single wire or multiple wires, which are, for example, twisted together with each other. The electrical conductor also includes an insulator coated around it. The conductor connection port generally only accommodates the wire.

[0014] A layout with a certain gap side by side of the first and second connection elements is generated, wherein the operating element of the connection element and the conductor connection port form a gap each. In this case, the operating element and the conductor connection port are located on an axis of the connection element. A matrix-like layout of the operating element and the conductor connection port in two rows and on the connection element is generated. The operating element and the conductor connection port of each connection element preferably have the same mutual distance in order to establish the layout of the operating element and the conductor connection port in two rows.

[0015] The connection element exactly includes these two rows, and the operating element and the conductor connection port are arranged in these rows. The operating element and the conductor connection port of each connection element are arranged in the first or second row.

[0016] In an advantageous embodiment, the connection unit has a plurality of first and second connection elements, and the first and second connection elements are arranged in an at least partially alternately adjacent manner. A layout including alternating first and second connection elements is at least partially formed. At least in this section, in each of the rows, the distance between adjacent conductor connection ports is the distance along the row between the first or second connection elements of the same type, that is, the distance is equal to the distance between the two connection elements. In this way, the distance between the conductor connection ports is maximized. At least in this section, a regular layout of the conductor connection port and the operating element in each of the two rows is generated.

[0017] In an advantageous embodiment, the first and second connection elements adopt the same structural implementation, wherein the second connection element is arranged in the connection unit in a manner that is twisted 180° relative to the first connection element. This also applies to the connection board. That is to say, the first and second connection elements are still arranged in parallel. More precisely, in order to form the first and second connection elements, the connection elements are arranged in anti-parallel. Accordingly, the operating elements and the attached conductor connection ports of each connection element have the same mutual distance. In this way, the operating elements and the conductor connection ports can be arranged in a straight line in the two rows. By using the same connection elements, the connection unit can be formed simply and at low cost.

[0018] In an advantageous embodiment, the connection elements are arranged with a pin size that is smaller than the flange diameter of the core wire end sleeve of the maximum usable connection cross-section of the conductor connection port. The pin size defines the distance of the side-by-side layout of each connection terminal. It gives the distance from a point of one connection element to the same point of an adjacent connection element. In the case where the connection elements are arranged side by side without an intermediate cavity, the pin size is equal to the width of the connection element. By arranging the connection elements side by side without an intermediate cavity, a compact connection unit is formed. The allowed size of the core wire end sleeve, especially its flange diameter, is obtained according to the cross-sectional area of the cable, which is a size allowed in terms of maintaining safety and is smaller compared to the prior art.

[0019] In an advantageous embodiment, the connection elements are implemented in such a way that after dividing the pin size by the maximum flange diameter, the obtained value is approximately 0.875. That is to say, for example, in the case where the maximum cross-sectional area of the connection unit is 4 mm 2 and the flange diameter is 5.4 mm, the pin size obtained after rounding up is 4.8 mm (5.4 × 0.875 = 4.725). The flange diameter is based on the core wire end sleeve with a corresponding cross-sectional area to be used in cooperation with the electrical conductor. In the prior art, a pin size equal to the flange diameter, i.e., 5.4 mm, is required. In this example, a pin size reduction of approximately 0.6 mm compared to the prior art is achieved.

[0020] In an advantageous embodiment, the connection elements are arranged with a pin size that is smaller than the outer diameter of the electrical conductor insulator of the maximum usable connection cross-section of the conductor connection port. By the adjacent layout of the first and second connection elements, a distance equal to twice the pin size is generated between the conductor connection ports of each row. Therefore, the connection elements can in principle adopt a narrower implementation, such that the insulator of the electrical conductor has extended beyond the corresponding connection element.

[0021] In an advantageous embodiment, the connection elements have a common housing in which the plurality of connection elements are arranged. A compact connection unit is provided, which enables the common installation of the connection elements. The connection elements are preferably integrally arranged in the housing and connected to the housing in the case of forming a connection board. The connection board is provided as an indivisible unit.

[0022] In an advantageous embodiment, the common housing is implemented as a housing for printed circuit board mounting. The connection unit can be used for printed circuit board mounting, such as a printed circuit board terminal block or a printed circuit board connector. In this case, the connection unit preferably includes pins that are inserted into or pass through the printed circuit board to mount the connection unit on the printed circuit board.

[0023] Particularly preferably, the pins are implemented as contact pins, which cause electrical contact between the conductor connection port and the printed circuit board. For example, the connection unit can be fixed on the printed circuit board by clamping. As an alternative or supplement, the pins are implemented as welding pins for fixing the connection unit on the printed circuit board by soldering. In an alternative embodiment, the housing can be implemented for printed circuit board mounting as follows: it is plugged onto the pin row of the printed circuit board, thereby enabling plug-in mounting. The pin row includes a plurality of pins, which are preferably implemented as contact pins for electrical contact.

[0024] In an advantageous embodiment, the connection element is implemented as a spring-loaded terminal with a clamping spring, which holds the electrical conductor in a clamped manner in the conductor connection port by its spring force, and the actuating element is implemented to release the clamping of the electrical conductor by the clamping spring during the actuation process. Therefore, in the case of using a spring-loaded terminal, the insertion of the conductor already causes the electrical conductor to be clamped in the corresponding conductor connection port, and the clamping can be released by actuating the attached actuating element. The spring-loaded terminal enables simple and reliable accommodation and contact of the electrical conductor in the conductor connection port. The clamping can also be simply released by the corresponding actuating element. In this case, by actuating the actuating element, the clamping spring is tensioned, thereby releasing the electrical conductor inserted into the conductor connection port, and the electrical conductor can be removed therefrom.

[0025] In an advantageous embodiment, the actuating element is embodied as an actuating button. The actuating button can release the clamping when being pressed towards the corresponding connection element, which is easy to implement. In this case, the actuating button generally acts directly against the clip spring, thereby tensioning the clip spring and canceling the clamping of the electrical conductor accommodated in the conductor connection. After actuation, the actuating button is reset by the restoring force of the clip spring. In addition, after actuation, the electrical conductor accommodated in the conductor connection is clamped in the conductor connection and contacted. Such an actuating button is also referred to as a so-called pusher.

[0026] In an alternative embodiment, the connection element can be provided with different actuating elements. These actuating elements include, for example, a pulling element or a lever element, or an actuating element provided with an eyelet, such that the actuating element can only be actuated by means of a special tool, thereby preventing accidental actuation.

[0027] In an advantageous embodiment, the connection element is embodied as a screw terminal, wherein the actuating element is embodied as an actuating screw, and the electrical conductor is clamped in and released from the conductor connection by means of these actuating screws. The electrical conductor can be reliably accommodated and fixed in the conductor connection by means of the screw terminal. By means of the actuating screws, the electrical conductor can be clamped in and released from the corresponding conductor connection in a controlled manner. Depending on the construction of the screw terminal, a deflection element can be provided, which converts the screwing-in of the actuating screw, thereby clamping or releasing the electrical conductor inserted parallel to the actuating screw in the conductor connection. For example, the rotational movement of the actuating screw can be deflected by an angle of 90° to the clamping screw.

[0028] In an advantageous embodiment, the connection unit has a first and / or second connection element, which comprises a conductor connection for accommodating electrical conductors with different maximum cross-sections. Any one of the first and / or second connection elements can be provided with a conductor connection for accommodating electrical conductors with any maximum cross-section and combined with each other. In this case, the layout of the conductor connections in the first or second row is based on, for example, the corresponding layout of the center points of the conductor connections.

[0029] In an exemplary embodiment, the connection unit has four, eight or sixteen parallel arranged connection elements. However, the present invention is not limited to a specific number of parallel arranged connection elements. Description of the Drawings

[0036] In the following description, the same reference numerals denote the same components or the same features. Therefore, the description of a component with reference to one drawing also applies to other drawings, thus avoiding repeated description. In addition, each feature described in connection with one embodiment can also be used alone in other embodiments.

[0037] Figure 1 A connection unit 10 in the prior art is shown. The connection unit 10 includes a plurality of connection elements 11 arranged in parallel, which are implemented as spring terminals and arranged in a common housing 12. Each of the connection elements 11 includes a conductor connection 13 and an operating element 14. The connection unit 10 is mounted on a printed circuit board 15, wherein the pins 16 of the connection unit 10 extend through the printed circuit board 15 and are soldered to the printed circuit board. As Figure 1 shown, electric conductors 17 are inserted into some of the conductor connections 13, and are held in the conductor connections 13 by the elastic force of a clamping spring (not shown). Manipulation can be performed through the attached operating element 14, whereby the clamping of the electric conductor 17 in the corresponding conductor connection 13 is released. The operating element 14 and the conductor connection 13 are arranged in two rows 18. The connection elements 11 arranged in parallel are arranged with a uniform pin pitch dimension 19.

[0038] Figures 2 to 4 Relates to the connection units 20, 32 of the first preferred embodiment of the present invention.

[0039] In this embodiment, the connection unit 20 includes sixteen connection elements 21, 32 arranged in parallel, which are arranged in a common housing 22. Specifically, the common housing 22 is implemented as a housing 22 for printed circuit board mounting. Therefore, the connection unit 20 is suitable for printed circuit board mounting like a printed circuit board terminal block or a printed circuit board connector.

[0040] In the first embodiment, the connection elements 21, 32 are each implemented as spring terminals 21. Correspondingly, each of the spring terminals 21 has a clamping spring 23, as Figure 2 and Figure 3 shown, in which the connection unit 20 is shown partially without the housing 22 in these figures. The clamping spring 23 holds the electrical conductor 26 in a clamped manner in the corresponding conductor connection port 24 by its elastic force.

[0041] Therefore, each of the spring terminals 21 includes a conductor connection port 24 and additionally includes a manipulation element 25. In this embodiment, the manipulation element 25 is implemented as a manipulation button 25 or a pusher. Based on the manipulation button 25, when pressed towards the corresponding spring terminal 21, the clamping of the electrical conductor 26 held by the clamping spring 23 is released. In this case, the manipulation button 25 acts directly against the clamping spring 23, so that the clamping spring 23 is tensioned during the pressing process, and the clamping of the electrical conductor 26 accommodated in the conductor connection port 24 is cancelled. After the manipulation, the manipulation button 25 is reset due to the restoring force of the clamping spring 23. In addition, after the manipulation, the electrical conductor 26 accommodated in the conductor connection port 24 is clamped in the conductor connection port and contacted. In the case of using the spring terminal 21, the electrical conductor 26 has been clamped in the corresponding conductor connection port 24 by inserting the electrical conductor 26.

[0042] The electrical conductor 26 has a respective potential. Among them, the electrical conductor 26 can include a single wire or a plurality of wires, and these wires are, for example, twisted together with each other.

[0043] The actuating element 25 and the conductor connection port 24 of the connection element 21 are arranged in two rows 29 spaced apart from each other on one side 30 of the connection unit 20. For this purpose, the connection unit 20 includes first and second resilient terminals 21a, 21b, which are arranged in an alternately adjacent manner. The first and second resilient terminals 21a, 21b adopt the same structural implementation, wherein the second resilient terminal 21b is arranged in the connection unit 20 in a manner that is twisted 180° relative to the first resilient terminal 21a. That is, the first and second resilient terminals 21a, 21b are arranged in an antiparallel manner. Correspondingly, with respect to the first resilient terminal 21a, the actuating element 25 is arranged in the first row 29a, and the conductor connection port 24 is arranged in the second row 29b. And with respect to the second resilient terminal 21b, the actuating element 25 is arranged in the second row 29b, and the conductor connection port 24 is arranged in the first row 29a.

[0044] A layout with a certain gap side by side of the first and second connection elements 21a, 21b is generated, wherein the actuating element 25 and the conductor connection port 24 of the resilient terminal 21 each form a gap. In this case, the actuating element 25 and the conductor connection port 24 are located on an axis of the corresponding resilient terminal 21. A matrix-like layout of the actuating element 25 and the conductor connection port 24 in the two rows 29 and in the resilient terminal 21 is generated. The actuating element 25 and the conductor connection port 24 of each resilient terminal 21 have the same mutual distance.

[0045] Especially from Figure 4 It can be seen that the adjacent resilient terminals 21 are arranged with a uniform pin pitch dimension 31. The pin pitch dimension 31 defines the distance of the side-by-side layout of the respective resilient terminals 21. It gives the distance from a point of a resilient terminal 21 to a substantially same point of the adjacent resilient terminal 21. In the case where the connection elements 21 are arranged side by side without an intermediate cavity, the pin pitch dimension 31 is equal to the width of the connection element 21. In the present embodiment, the width of the connection element 21 is equal to the pin pitch dimension 31.

[0046] In the present embodiment, the pin pitch dimension 31 is smaller than the flange diameter of the core wire end sleeve of the maximum usable connection cross-section of the conductor connection port 24. Specifically, the resilient terminal 21 is implemented such that the value obtained by dividing the pin pitch dimension 31 by the maximum flange diameter is approximately 0.875. That is, for example, when the maximum cross-sectional area of the conductor connection port 24 of the connection unit 21 is 4 mm 2 And the flange diameter is 5.4 mm, the rounded-up pin pitch dimension is 4.8 mm (5.4 × 0.875 = 4.725). The flange diameter is based on the core wire end sleeve with a corresponding cross-sectional area to be used in cooperation with the electrical conductor 26.

[0047] The connection unit 20 is mounted on the printed circuit board 27, where the pins 28 extend through the printed circuit board 27 and are soldered to the printed circuit board, as Figure 4 shown. In the present embodiment, the pins 28 are implemented as contact pins, which are connected to the clamping springs 23 of the respective resilient terminals 21 for contacting the printed circuit board 27, and cause an electrical connection between the conductor connection ports 24 and the printed circuit board 27. The pins 28 pass through the printed circuit board 27 to mount the connection unit 20 on the printed circuit board, in particular by soldering.

[0048] In an alternative embodiment, the resilient terminals 21 are arranged with a pin size 31 that is smaller than the outer diameter of the insulator of the electrical conductor 26 with the maximum usable connection cross-section of the conductor connection port 24. By the adjacent layout of the first and second resilient terminals 21a, 21b, a distance equal to twice the pin size 31 is created between the conductor connection ports 24 of each row 29, such that the insulator of the electrical conductor 26 projects beyond the respective resilient terminals 21.

[0049] In the second embodiment as Figure 5 shown, the connection elements 21, 32 are implemented as screw terminals 32. Otherwise, the connection unit 20 of the second embodiment is equivalent to the connection unit of the first embodiment. The description made above in connection with the resilient terminals 21 applies correspondingly to the screw terminals 32.

[0050] Corresponding to the technical solution of implementing the connection elements 21, 32 as screw terminals 32, the actuating elements 25, 33 are implemented as actuating screws 33. In the present embodiment, depending on the rotation direction of the actuating screw 33, the electrical conductor 26 can be clamped in and released from the conductor connection port 24 by the actuating screw 33.

[0051] Depending on the construction of the screw terminals 32, a deflection element (not shown here) can be provided, which converts the screwing-in of the actuating screw 33, so as to clamp or release the electrical conductor 26 inserted parallel to the actuating screw 33 in the conductor connection port 24. For example, the rotational movement of the actuating screw 33 can be deflected by an angle of 90° to a clamping screw.
