Description

[Technical field]

[0001] The invention relates to a plug-in terminal for connecting one or more conductor ends, to a plug-in connector with one or more such plug-in terminals and to a module consisting of such a plug-in terminal and / or plug-in connector. [Background technology]

[0002] Modules consisting of plug-in terminals, in particular as part of plug-in connectors, are known from the prior art in various configurations.

[0003] Within the scope of this document, a plug-in terminal comprises a housing with one or more connection devices for plugging in and electrically conductively connecting a conductor end (or plug or the like) to a busbar, each of which is assigned an operating device.

[0004] Each busbar may also be connected to a plug-in terminal, which then also constitutes a plug-in connector for connection to a corresponding plug-in connector. However, each busbar may also be connected to another device, i.e. a solder terminal, which is used to connect the plug-in terminal to a printed circuit board, which then constitutes the printed circuit board connector. Other configurations are possible.

[0005] Within the scope of the present application, the term "module of plug-in terminals and possibly plug-in connectors" in this case particularly includes a higher-level multi-disk plug-in terminal configured as a multi-disk plug-in terminal and possibly as a multi-disk plug-in connector which can be mated with a corresponding counter-plug-in connector. The multi-disk plug-in terminal and possibly the multi-disk plug-in connector have a number of plug-in terminals and possibly plug-in connector disks arranged next to one another and directly mechanically connected to one another by mechanical connection means in the form of a rail. However, the module of plug-in terminals can also be designed in another way, for example for further connection to a printed circuit board.

[0006] According to EP 0 984 513 A1, a plug-in terminal, which is also designed as a plug-in connector, has an insulating, disk-shaped plastic housing which has at least two connection devices for the electrical lines reached and at least two pin or socket contacts, each of which is connected to a connection device and can be connected to a corresponding plug-in connector.

[0007] The plug-in terminals according to EP 0 984 513 A1 are to be further optimized with regard to the narrow design form of the individual plug-in terminals.The object of the present invention is to solve this problem. Summary of the Invention [Means for solving the problem]

[0008] The invention solves this problem by the subject matter of claim 1. Advantageous configurations can be seen from the dependent claims.

[0009] According to claim 1, there is provided a plug-in terminal for connecting one or more conductor ends, which has a housing made of a non-conductive material, in particular plastic, which has at least one plug opening for each conductor end, each of which is connected to a respective housing chamber which has a respective connecting device to which a respective operating device is assigned, which operating device is provided for operating a contact leg of a contact spring of the connecting device, the operating device having a pivot lever designed to act on a sliding element which can directly or indirectly move the contact leg of the contact spring, the pivot lever and the contact leg being pivotable about the same or substantially the same pivot axis.

[0010] As a result of this constructional form, the construction space requirements of the connecting device with the actuating device are extremely low. It is, in principle, known to align the pivot axis of the pivot lever of the actuating device with the pivot axis of the clamping leg of the contact spring. However, it has not been realized so far that this measure has a particularly advantageous effect precisely in the case of an actuating device as a combination of a pivot lever and a sliding element. In this case, the pivot lever preferably acts on the sliding element. In such a combination, according to the prior art, the pivot axes of these elements are not aligned, since the pivot lever is usually arranged at a considerable distance from the contact spring. However, this results in a less compact construction.

[0011] The invention can be realized particularly well and simply in terms of construction if the contact spring is substantially V-shaped and each pivot lever is pivotally supported on a pin of the housing, which is the same pin or is formed concentrically relative to a pin of the housing with which the approximately V-shaped contact spring engages from above.

[0012] However, other forms of support are possible.

[0013] Optionally, it may be specified that the sliding element can be locked in a sliding position in which the contact leg is held in the open position for introducing the conductor, or that the contact leg itself can be locked in the open position for introducing the conductor, and that a device for unlocking this is provided. In this way, locking in the open position can also be achieved simply for connecting devices with a combined pivot lever-sliding element operation and locking in the open position. In this case, it may be specified, more significantly, that a device for unlocking the sliding element and / or the contact spring is operated when introducing the conductor.

[0014] Measures which further promote a compact construction can be specified in that the sliding element is slidably guided in the housing for operating the contact leg and is additionally slightly tiltable and / or rotatable for locking and unlocking.

[0015] Various constructional configurations are thus possible, so that the pivot lever and the respective contact spring can be arranged next to each other in parallel planes in the housing, however, it is also possible for the pivot lever and the contact spring to be completely or substantially arranged in one common plane in the housing.

[0016] Furthermore, according to a further refinement, it can advantageously be specified that the respective plug opening is arranged in a housing top surface of the housing.

[0017] According to a preferred embodiment, it can be advantageously specified that each connecting device is formed as a direct plug-in contact, each spring-loaded, since in this embodiment the invention can be realized particularly well structurally. A particularly simple, tool-free contact connection of the conductor ends is achieved. This contact connection is again further simplified if the contact springs can be locked in an open state, from which they can be released by introducing the conductor ends into the housing.

[0018] The invention also provides a plug-in connector having one or more plug-in terminals according to one or more of the preceding claims, in which the first busbar sections are extended and together with the respective second busbar sections or alternatively form a plug-in contact in each case, by means of which the plug-in connector can be contact-connected to a counter-plug-in connector, whereby, due to functional integration, a compact design of the contact for connection to the counter-plug-in connector is provided.

[0019] However, one or more plug-in terminals arranged juxtaposed to one another may also be provided with solder terminals electrically conductively connected to a respective connection device for contact-connecting a printed circuit board.

[0020] Optionally, it may be specified that each housing of the plug-in connector (disk) has at least two plug openings for the conductor ends, a first plug opening connected to a first housing chamber and a second plug opening connected to a second housing chamber, the first housing chamber having a first connecting device and the second housing chamber having a second connecting device, the housing has a first housing half and a second housing half, and the first housing half can be imaged onto the second housing half if it is rotated about a point of symmetry S or an axis of symmetry, whereby the housing is formed substantially or completely rotationally symmetrical with respect to the point of symmetry S or the axis of symmetry S on which the point of symmetry S is located.

[0021] In this way, a respective plug-in connector is provided with optimized air and creepage distances. It also becomes possible to use a large number of identical parts when producing this plug-in connector, since the housing chamber and the connecting device arranged therein are arranged at a distance from each other in both housing halves rotated relative to each other on opposite sides of the housing. This results in large or optimized air and creepage distances. Furthermore, the connecting device can be produced from identical parts on both sides and does not have to be formed mirror-symmetrically in two forms for the left and right housing halves (which according to the prior art open towards the same side). Furthermore, this makes it particularly simple to juxtapose further plug-in connectors in two different juxtaposition directions starting from a first plug-in connector. This allows the plug-in connector to be used in an advantageously flexible manner. In this case, it is particularly advantageous if the two housing halves are oriented rotated by 180° relative to each other and are preferably connected together. Although these options are advantageous, they do not necessarily have to be specified within the scope of the invention.

[0022] Further advantageous configurations of the subject matter according to the invention can be found in the dependent claims.

[0023] The invention is explained in more detail below on the basis of an embodiment with reference to the drawings. Further advantageous variants and configurations are also described. It is to be emphasized that the embodiment described below is not to be regarded as an exclusive description of the invention, and that variants and equivalents not shown are also possible and are included in the scope of the claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0025] The terms "vertical", "vertical", "horizontal", "up", "down", "right" and "left" used below relate to the respective figures. The spatial coordinate system in each figure is used for further orientation purposes.

[0026] 1 shows, in its parts a) to f), firstly a substantially disk-shaped single-disk plug-in connector 1. This single-disk plug-in connector 1 can be mated with a counter-plug-in connector. This counter-plug-in connector (not shown) can be formed, for example, as a section of a serial terminal or as a section of an electrical device.

[0027] The corresponding plug-in connectors may be juxtaposed on a support rail or a printed circuit board or the like. Each single-disc plug-in connector 1 may be juxtaposed with another single-disc plug-in connector 1 of the same or substantially the same construction form, whereby a higher-level multi-disc plug-in connector 100 is then obtained which is combined from a number of single-disc plug-in connectors 1. In the following, each single-disc plug-in connector 1 or each plug-in connector disk is also referred to as plug-in connector for short.

[0028] The multi-disc plug-in connector 1 of Figures 1a) to 1f) preferably comprises at least one or more plug-in connector discs or plug-in connectors, each of which comprises a substantially or exactly rotationally symmetrical housing 2, which is preferably made from a non-conductive material, for example plastic, and each plug-in connector 1 comprises plug-in terminals, to which conductor ends are connected.

[0029] The term "rotationally symmetric" means here that the housing 2 is mirror symmetric about a single point of symmetry S and is even imaged onto itself.

[0030] The symmetry point S is located at the imaginary intersection of two center lines M1, M2 in Figures 1c, 2c and 3c, respectively, which bisect the length L and width B with respect to the housing top surface 5 (coordinate system parallel to the xy plane shown in Figures 1a, 1b and 1c) of the housing 2. This also applies to any plane parallel to the xy plane with respect to the entire housing 2, whereby imaginary symmetry axes passing through the symmetry point S on these planes are generated parallel to the z axis.

[0031] In other words, if the first housing half 8a is "assumed" to be rotated clockwise by 180° about the point or axis of symmetry, this first housing half 8a will be imaged onto the second housing half 8b. In this respect, the housing 2 as well as the first and second housing halves 8a and 8b are also referred to as being inversion-symmetric or rotationally symmetric with respect to the point of symmetry S.

[0032] The housing 2 of Figures 1 to 3 has at least one, in the illustrated configuration exactly two plug openings 3a, 3b for each conductor end. The first plug opening 3a and the second plug opening 3b are arranged in the illustrated configuration on the housing top surface 5 of the housing 2. The plug openings 3a, 3b may also be arranged obliquely or laterally. Each plug opening 3a, 3b extends towards the first housing chamber 4a and towards the second housing chamber 4b.

[0033] In the illustrated configuration, the first housing chamber 4a substantially occupies the first housing half 8a, and the second housing chamber 4b substantially occupies the second housing half 8b.

[0034] The first housing chamber 4a has a first connecting device 6a, the second housing chamber 4b has a second connecting device 6b, which in the illustrated configuration are arranged in the respective housing chambers 4a, 4b with mirror symmetry or also with rotational symmetry with respect to one another.

[0035] Within the scope of this illustration, but also within the scope of the entire description, the housing 2 firstly comprises one or more connection devices 6a, 6b, each assigned to an actuating device 10a, 10b, for plugging in a conductor end (or plug or the like) which is conductively connected to a busbar 13, forming a plug-in terminal. Each busbar 13 may then be connected to a plug-in contact. In this case, the plug-in terminal also forms a plug-in connector. The plug-in connector may have several plug-in terminals. In this case, several connection devices 6a, 6b for conductor ends with the respective actuating device 10a, 10b are provided in the housing 2. The actuating devices 10a, 10b are each formed with a plug-in contact for connecting to a corresponding plug-in contact of a corresponding plug-in connector.

[0036] The housing 2 of the plug-in terminal, in the illustrated configuration of the plug-in connector 1, has at its front side VS (as shown in FIG. 1a) a first housing wall 7a. In the illustrated configuration, this first housing wall 7a closes only the second housing chamber 4b, which is arranged on the right side in FIG. 1a. In contrast, the first housing chamber 4a, which is arranged on the left side at the front side VS of the housing 2 in FIG. 1a, is open, so that in the illustrated configuration the first connecting device 6a can be seen. The first housing chamber 4a is therefore open outwards at the front side VS of the housing 2.

[0037] As a result, the housing chambers 4a, 4b or the connection devices arranged in the housing chambers 4a, 4b and generally both metal assemblies are arranged at a distance from each other in both housing halves rotated relative to each other on opposite sides of the housing, thereby resulting in large or optimized air and creepage distances.

[0038] The housing 2 of the plug-in terminal has a second housing wall 7b on its rear side RS (not shown in FIG. 1a, see reference number in FIG. 1c), which likewise closes only one of the two housing chambers, namely the first housing chamber 4a. This first housing chamber 4a is arranged in one housing half so that it is located on the right side when the housing 2 is viewed from the rear side RS. In contrast, the second housing chamber 4b, which is located on the left side when viewed from the rear side RS, is open. This second housing chamber 4b is therefore open towards the outside at the rear side RS of the housing 2 and is arranged in the other housing half.

[0039] The first housing chamber 4a (on the left side as viewed in Figure 1a) at the front side VS of the housing 2 is closed by juxtaposing the housing 2 of a geometrically identical second plug-in connector 1 to the housing 2 of the first plug-in connector 1 shown in Figure 1a at the front side VS of the existing plug-in connector 1 in a first juxtaposition direction A1, i.e. in the negative x-direction based on the coordinate system shown in Figure 1a.

[0040] Analogously, the second housing chamber 4b at the rear side RS of the housing 2 is closed by juxtaposing the housing 2 of a geometrically identical third plug-in connector 1 (not shown in Figure 1a, see Figures 1b and 1c) to the housing 2 of the first plug-in connector 1 shown in Figure 1a at the rear side RS of the existing plug-in connector 1 in a second juxtaposition direction A2, i.e. in the positive x-direction based on the coordinate system shown in Figure 1a.

[0041] Due to the housing 2 being open on one side, either at the front side VS or at the rear side RS, the plug-in connectors 1 shown in Figures 1a to 1f can advantageously be juxtaposed to one another in two different juxtaposition directions A1, A2.

[0042] The first juxtaposition direction A1 extends in the negative x-direction based on the coordinate system shown in Fig. 1a. The second juxtaposition direction A2 extends in the positive x-direction based on the coordinate system shown in Fig. 1a. This results in a flexible and simple assembly and a high degree of uniformity of parts, since no matter in which juxtaposition direction A1, A2 the next plug-in connector is juxtaposed, a geometrically identical housing 2 can always be used.

[0043] In order to ensure that the plug-in connectors 1, 1', 1'' are juxtaposed in the correct orientation, the housings 2 each have a form-locking element 21a, b, which also serves as an juxtaposition aid. The form-locking elements 21a, b are designed in such a way that the form-locking elements of adjacent housings or plug-in connectors in the module of the plug-in connectors 1, 1', 1'', which are respectively configured as pins and recesses, engage with one another substantially form-lockingly. If the juxtaposition of the plug-in connectors 1, 1', 1'' is incorrect, the plug-in connectors 1, 1', 1'' would therefore be assembled with a gap between the housings 2, 2', 2''. The form-locking elements 21a, b thus prevent the plug-in connectors 1, 1', 1'' from being juxtaposed in the wrong orientation and stabilize the module.

[0044] For connecting juxtaposed plug-in connectors 1, 1', 1'' or their housings 2, 2', 2'' to one another, each housing 2, 2', 2'' further comprises first and second locking means 9a, 9b.

[0045] The first locking means 9a is arranged in the illustrated configuration on the right side at the front side VS of the housing 2 shown in Fig. 1a and is also arranged on the right side when looking at the rear side RS of the housing 2. The second locking means 9b or a corresponding locking means (not shown in Fig. 1a) is therefore located on the left side at the front side VS of the housing 2 and is also located on the left side when looking at the rear side RS of the housing 2 (see also Fig. 1b and 1c in this regard). The first locking means 9a can be formed, for example, as a locking hook and the corresponding locking means can be formed as a locking latch.

[0046] The multi-disk plug-in connector 1 of Figures 1a) to 1f) can, in the variants of the part of Figure 1, have a housing 2 that is substantially or exactly rotationally symmetrical. However, this advantageously does not necessarily have to be the case. In the parts of Figures 2 and 3, Figures 2a) to 2h) and 3a) to 3g) further variants of the plug-in connector or plug-in connector disk are shown in which this is not the case.

[0047] The one or two connection devices 6a, 6b (also called metal assemblies) per disk are in the illustrated configuration each configured as a pressure spring terminal, preferably as a direct plug-in terminal. It is advantageous to configure the connection devices 6a, 6b in the direct plug-in technology as pressure spring terminals, since the pressure spring terminals allow the contact connection to be made without tools, which in the illustrated configuration can also be released again without tools. Alternatively, other types of terminals with contact springs can also be provided, for example in tension spring technology. Furthermore, a plurality of terminals for conductors can also be provided per housing 2.

[0048] Each connecting device 6a, 6b has a respective operating device 10a, 10b which in the illustrated configuration is provided for tensioning the contact clamp legs 11a, 11b (called contact legs and contact springs for short) of the contact clamp springs 12a, 12b of the connecting devices 6a, 6b in order to open the contact clamping points and for locking these contact clamp legs 11a, 11b preferably also in the open position.

[0049] Each operating device 10a, 10b has, in the illustrated embodiment, a pivot lever 110 which is pivotally mounted in the housing 2. This pivot lever 110 acts via a sliding element 120 on the respective contact spring 12a, 12b, thereby opening the latter. Optionally, the contact springs 12a, 12b can be preloaded in the open position (see Figs. 2g and 2h without contact spring and Fig. 3g with contact spring), so that the contact springs 12a, 12b can be relaxed by the conductor. This conductor is introduced into the housing 2, in the process releasing the preload and is then clamped by the contact legs against the busbar sections 13a, b and thus contact-connected. For this purpose, the conductor can be contact-connected to an actuating element 130 which, in the illustrated embodiment, is formed as a locker which strikes when introduced into the housing 2.

[0050] Thus, a contact is made upon insertion of the respective (insulation-removed) conductor end into the respective plug-in opening 3a, 3b, whereby the preload of the contact springs 12a, 12b is released by the action of the rocker 130, which allows the contact legs 11a, 11b to press the respective conductor end against the first busbar sections 13a, 13b.

[0051] The contacts can be released by means of an operating device, which in the illustrated configuration has as elements a pivot lever 110 and a sliding element 120, capable of pressing the contact legs 11a, 11b of the contact springs 12a, 12b, respectively, so that the contact springs 12a, 12b can be opened again and, optionally, preloaded, for contacting the conductor ends (not shown). For this purpose, a lock 140 is provided, which allows one or more elements of the connecting device 6a, 6b and / or the operating device 10a, 10b assigned to the connecting device 6a, 6b to be locked again in the open position, whereby the introduction of the conductors is possible, possibly by operating the locker 130, in order to initiate the connection again.

[0052] It is therefore expedient if the sliding element 120 can be locked in the housing 2, thereby holding the contact legs 12a, 12b in the open position. Locking of the contact legs 12a, 12b is, for example, advantageously possible, but is not necessarily an option. The connecting device, in the illustrated configuration the direct plug-in terminal, can also be configured as a direct plug-in terminal that is not lockable in the open position. In this case, prior to the insertion of the conductor, the contact legs 12a, 12b must first be pivoted by means of an actuating device, so that they are moved into the open position, in which the conductor can then be introduced into the clamping point. The actuating device is then released or released, so that the contact legs 11a, 11b press the conductor against the busbar section 13a.

[0053] According to Figures 1 to 3, it is specified that the sliding element 120 can be easily tilted and / or pivoted even within the housing 2 in order to engage with a locking edge 122, e.g. a housing locking edge 23 (see Figure 3g) of the housing 2.

[0054] It is particularly advantageous if the pivot lever 110 and the contact springs 6a, 11a have the same pivot axis D. This means that the pivot axis D of the pivot lever 110 and the pivot axis D about which the clamping legs 11a, 11b are pivoted are completely or in any case substantially aligned or are formed completely or substantially concentrically.

[0055] As a result of this constructional form, the required construction space is extremely low. It is, in principle, certainly known to align the pivot axis D of the pivot lever 120 of the actuating device with the pivot axis D of the clamping legs of the contact spring. However, it has not been realized so far that this measure also has a particularly advantageous effect in the case of an actuating device in combination with a pivot lever 110 which acts on the sliding element 120 to release the contact legs 11a, 11b. In such a combination, according to the prior art, the pivot lever 120 is usually arranged so far away from the contact springs 12a, 12b that the pivot axes D of both these elements are not aligned. However, this results in a less compact construction.

[0056] Thus, the actuating devices 10a, 10b each have, according to Figs. 1 to 3, a pivotally mounted pivot lever 110. Each pivot lever 110 can have a disk section 1101 (Fig. 2b) in which the pivot lever 110 is pivotally mounted in the housing 2 and is adapted to actuate a slide element 120. Each disk section 1101 can be provided with a pivot lever arm 1102 for actuation by the user, which can protrude from the disk section 1101, for example in a substantially radial direction. The disk section 1102 can be provided with an actuating section 1103, which in the illustrated embodiment is formed, for example, by an edge of the disk section. This actuating section 1103 acts on the slide element 120 and serves to convert the pivoting movement of the pivot lever 119 into a substantially linear movement of the slide element 120. Furthermore, an arm 1104 may be provided for manually pivoting the pivot lever 110. The sliding element 120 may have means, such as a protrusion 121 or the like, by which the pivot lever 110 can act with its operating section 1103.

[0057] In the illustrated configuration, the sliding element 120 is dimensioned or elongated so that it reaches up to the area of ​​the rocker 130. In this case, the sliding element 120 and the rocker 130 are adjusted to one another in such a way that, when a conductor is introduced, the conductor operates the rocker 130, which in turn can pivot the sliding element 120 slightly in the sliding path, so that the sliding element 120 can be released from a locking position provided on the housing 1 or from a locking position provided on another element (see, for example, FIG. 2h).

[0058] The pivot lever 110 can be, for example, pierced by a pin 22 of the housing 2 in the region of the pivot axis D, which also serves as an axle pin of the pivot lever 110. The contact spring 10 can also be mounted on the housing, in particular on this pin 22. The contact spring 10 is preferably V-shaped and is mounted on the pin 22 of the housing 2 with an arc that forms, as it were, the tip of the V. In this case, if the pivot lever 110 surrounds the contact springs 12a, 12b in a U-shape, two bearing points can be realized for the pivot lever 110. These two bearing points are located axially with respect to the region in which the contact springs 12a, 12b engage the pin 22 from above.

[0059] According to figures 1a) to 1g), it is specified that the pivot lever 2 is preferably arranged laterally with respect to the contact springs 12a,b. In this case, both elements are completely or substantially arranged in two parallel and adjacent planes in the housing 2. Such an arrangement is shown in figures 2a to 2h. This arrangement has the advantage that the connecting device with the actuation device can be made very compact and the individual elements of the connecting device, for example the pivot lever 110, can be made particularly simple and inexpensive.

[0060] However, it may be advantageously specified that the pivot lever 110 and the contact springs 12a, 12b lie completely or substantially in one common plane. Such an arrangement is shown in figures 3a to 3g). This arrangement is particularly stable and safe, since in the arrangement shown tilting points of the pivot lever 120 are particularly well avoided.

[0061] The first busbar sections 13a, 13b in the illustrated configuration each extend vertically downwards, i.e. in the negative z-direction based on the coordinate system shown in FIG. 1a, and together with the respective second busbar sections 15a, 15b each form a plug-in contact, in the illustrated configuration a tulip-shaped contact or a socket contact, by means of which the plug-in connector 1 formed as a plug-in terminal can be plugged into a corresponding plug-in connector. The plug-in contacts can be contact blades or pin contacts. However, instead of this, soldered contacts or the like can also be formed (see FIGS. 3a to 3g). The plug-in or soldered contacts or the like can be arranged in the plug-in direction -Z of the vertical extension or conductor end of the busbars 13a, b. However, the plug-in or soldered contacts or the like can also be arranged at an angle thereto. [Explanation of symbols]
