Description

Technical Field

[0001] This invention relates to a terminal block having a housing and a plurality of wire clamping connectors, wherein at least one electrical wire can be clamped at a clamping location by means of spring force at each wire clamping connector, wherein the wire clamping connectors are arranged in a ring shape around a center within the housing, and wherein the terminal block has a sliding actuating element having a manual operating surface for manually operating the plurality of or all of the wire clamping connectors and / or the electrical wires. The housing can be configured as an insulating material housing. The invention also relates to an electrical plug connector having at least one terminal block of this type, particularly a circular plug connector. Background Technology

[0002] This type of terminal block and plug connector is known from DE 20 2021 101 354 U1. Summary of the Invention

[0003] The purpose of this invention is to further improve such terminal blocks and plug connectors.

[0004] In the type of terminal block described at the beginning, the objective is achieved by the following: the sliding operating element is movably supported in the housing along the longitudinal direction of movement, and / or the manual operating surface of the sliding operating element is located in the central region of the terminal block between the wire clamping connectors. The present invention achieves a compact terminal block structure because multiple wire clamping connectors can be arranged in a space-saving annular shape, for example, by arranging the wire clamping connectors on circular rails within the housing. Here, the wire clamping connectors are preferably evenly distributed on the circular rails. Here, the central region, viewed in a plane perpendicular to the direction of movement, lies between the wire clamping connectors, so that the manual operating surface does not necessarily lie directly between the wire clamping connectors in all operating states. Here, the housing can, in principle, have any outer contour. Advantageously, the housing is designed as a circular housing, for example, having a cylindrical shape, with the longitudinal direction of the housing aligned with the longitudinal direction of movement of the sliding operating element.

[0005] With this sliding actuating element, it is feasible to easily and ergonomically manipulate multiple or all wire clamping connectors and / or electrical wires of the terminal block. Furthermore, this sliding actuating element can be well integrated structurally into the terminal block, especially in the form of a centrally located sliding actuating element, such as an actuating press. Unlike rotary actuating elements or pivotable levers, in the sliding actuating element, the desired actuating movement of the wire clamping connector is achieved solely through movement in the longitudinal direction of movement. When the sliding actuating element is manipulated at the manual operating surface, it shifts from its initial position to the operating position, for example, against a spring force. This shift of the sliding actuating element actuates the corresponding wire clamping connector and / or electrical wire.

[0006] The wire clamping connector can be selectively designed, for example, as a spring-force clamping connector with clamping springs or as a cut-clamp type clamping connector, and can also be combined with each other if necessary, as will be explained below. When the wire clamping connector is designed as a spring-force clamping connector, the clamping spring can be deflected to the open position by a sliding operating element, for example, by deflecting the clamping leg of the clamping spring. If the wire clamping connector is configured as a cut-clamp type clamping connector, the sliding operating element can cause relative movement between the wire to be connected and the provided cut-clamp type clamping connector, and the wire is securely clamped in the cut-clamp gap at the clamping part by this relative movement. Here, depending on the structure of the terminal block, the sliding operating element can move only the wire, only the cut-clamp type clamping connector, or both components.

[0007] As described above, the manual operating surface of the sliding operating element can be disposed in the central region of the terminal block, which is located between the wire clamping connectors. In particular, at least a portion of the sliding operating element can be disposed between the wire clamping connectors. At least in at least one operating state of the sliding operating element, the operating surface of the sliding operating element can also be disposed between the wire clamping connectors.

[0008] According to an advantageous design of the invention, the longitudinal direction of movement of the sliding actuating element is orthogonal to the planar extension defined by the annular shape of the wire clamping connector. This allows for reliable operation of multiple wire clamping connectors with a single sliding actuating element while simply implementing the actuating mechanism. The longitudinal direction of movement can, for example, extend centrally through the annular arrangement of the wire clamping connectors, as if it were the longitudinal axis of a terminal block. The terminal block can define a wire introduction direction for each wire to be introduced, for example, determined by features of the housing, in which the wire is introduced into the corresponding wire clamping connector or housing. The wire introduction direction of one, more, or all of the wire clamping connectors can here extend parallel to the longitudinal direction of movement of the sliding actuating element.

[0009] According to an advantageous embodiment of the invention, by manipulating a sliding operating element at the manual operating surface, the clamping portion of the wire clamping connector can be opened and / or the corresponding wire can be clamped at the wire clamping connector. The sliding operating element thus performs the necessary operating movement at the wire clamping connector or the wire, so that the wire can ultimately be clamped onto the provided clamping connector.

[0010] According to an advantageous design of the invention, by manipulating a sliding actuating element at a manual operating surface, the corresponding wire clamping connector and / or electrical wire can be subjected to an actuating force in a radial and / or axial direction relative to the annular shape of the wire clamping connector. This allows the electrical wire to be connected to the corresponding wire clamping connector by means of a relatively simple, easy-to-implement, and compact actuating mechanism. In the radial direction, the radial direction can be, for example, radially inward or radially outward. In the axial direction, the direction can be parallel to the longitudinal movement direction of the sliding actuating element.

[0011] According to an advantageous design of the invention, the sliding actuating element is torsionally supported within the housing. This ensures that the wire clamping connector is always actuated by the sliding actuating element at the position provided for this purpose. Furthermore, torsion and / or skewing of the sliding actuating element during movement is prevented. The sliding actuating element is particularly torsionally supported about its longitudinal axis formed by the longitudinal direction of movement.

[0012] According to an advantageous design of the invention, each wire clamping connector is provided with a wire inlet opening for introducing the electrical wire to be clamped at the wire clamping connector. This allows the user to easily and reliably attach the electrical wire to be connected to the corresponding wire clamping connector. The wire inlet openings can all be located on the same housing side of the terminal housing, that is, on the wire inlet side of the housing.

[0013] According to an advantageous design of the invention, at least one actuation profile and / or at least one actuation element are provided radially outward of the sliding actuation element for actuating the corresponding wire clamping connector and / or electrical wire. This allows for efficient transmission of actuation force to the wire clamping connector or electrical wire during the movement of the sliding actuation element. For example, a wire clamping connector may be provided with exactly one actuation profile and / or one actuation element, and vice versa.

[0014] According to an advantageous design of the invention, the actuation profile is configured as a sloping outer profile having at least one raised portion and / or a recessed portion. This allows for reliable and uniform actuation of the wire clamping connector.

[0015] The sliding control element has an outer contour extending parallel to the longitudinal movement direction, located radially outside the sloping outer contour behind it. This has the advantage that, when the sliding control element is in the operated state—that is, when the wire clamping connector is, for example, in the open position—the force of the wire clamping connector holds the sliding control element in the operated position, and it does not need to be held in the operated position by the user.

[0016] According to an advantageous design of the invention, one, several, or all wire clamping connectors are configured as spring-force clamping connectors, each having at least one clamping spring and a busbar disposed on the clamping spring, the busbar and the clamping spring forming a clamping portion for clamping the electrical wire. In this manner, the wire clamping connector can be configured using proven clamping spring connection technology. The clamping spring can be configured, for example, as a cage spring, leg spring, or other type of clamping spring, particularly as a V-shaped clamping spring or annular clamping spring. The electrical wire is then, for example, securely clamped between the clamping legs of the clamping spring and the busbar.

[0017] According to an advantageous design of the invention, one, several, or all clamping springs each have at least one clamping leg, a spring bow connected to the clamping leg, and a support leg connected to the spring bow. The clamping leg may have a clamping ridge on the side facing the busbar or clamping portion, by which the electrical conductor can be securely clamped. The support leg is used to support and secure the clamping spring. The clamping spring is supported by the spring force of the clamping leg, for example, by supporting it on another component of the busbar or terminal block, via the support leg.

[0018] According to an advantageous design of the invention, the corresponding spring bow and / or the corresponding clamping leg extend radially inward beyond the respective busbars. This allows for simple manipulation of the corresponding clamping spring by a sliding actuating element, for example, by bringing the actuating profile or actuating element into contact with the spring bow and / or clamping leg as previously described, thereby deflecting the clamping leg.

[0019] According to an advantageous design of the invention, the clamping leg of the clamping spring can be moved to an open position by manipulating a sliding operating element at the manual operating surface. In the open position, at least the clamping edge of the clamping leg pivots away from the contact section of the bus. The clamping leg is, for example, pivotable between an open position and a clamped position, in which the conductor can move freely between the clamping leg and the contact section, and in which the clamping leg clamps the conductor at the contact section.

[0020] According to an advantageous design of the invention, the terminal block has a retaining element for one, more, or all of the clamping springs, the retaining element being configured to hold the clamping leg of the respective clamping spring in the open position. Thus, even when no actuating force is applied to the spring bow and / or clamping leg by the sliding actuating element, the clamping leg can still be held in the open position by the retaining element. This structure allows for the integration of automatic triggering technology into terminal blocks of different structural forms. In particular, proven terminal blocks of known structural forms can improve the automatic triggering function with minimal cost, i.e., by means of automatic wiring of the conductor to be clamped, wherein the clamping leg is held in the open position by the retaining element and can be automatically released upon insertion of the conductor. Therefore, insertion of the conductor can induce a firm clamping of the conductor, thereby releasing the clamping leg's fixation at the retaining element.

[0021] The retaining element can be movably configured, for example, movably, pivotally, or otherwise deflectably configured, such that the retaining element can be slightly deflected by an inserted wire to achieve a desired release effect between the clamping leg and the retaining element. The retaining element can be movably supported, for example, movably supported in a straight or arcuate direction. The retaining element can be pivotally supported. In this case, the retaining element can pivot about a fixed or variable pivot axis. In the case of a variable pivot axis, the retaining element can, for example, be floatably pivotally supported. The retaining element can also perform combined movement and pivoting movements. The retaining element can also be otherwise movably supported such that the retaining element can be deflected sufficiently far to release the clamping leg's latch at the retaining element.

[0022] The retaining element, especially a component unrelated to the sliding actuation element, is able to hold the clamping leg in place when it has been moved to the open position, for example, by the sliding actuation element. Then, even when the sliding actuation element is released or returns to its original unoperated position, the clamping leg remains in the open position by the retaining element.

[0023] Advantageously, all clamping parts can be opened simultaneously by means of the sliding operating element, and the clamping springs can hold them in the open position at their respective retaining elements. Subsequently, connections can be established sequentially by inserting electrical wires individually. For this purpose, it is advantageous that the sliding operating element returns to its original unoperated position, for example, by a reset element, such as a reset spring, either separately or integrated into the sliding operating element. Thus, for connecting wires, it is not necessary for all wires to be held in the connected position simultaneously.

[0024] The retaining element can act directly on the clamping leg to hold the clamping leg in the open position. Therefore, for example, a first locking element can be provided at the clamping leg and a second locking element at the retaining element, wherein in the open position, the first and second locking elements can lock into each other. The first locking element can be configured as a locking protrusion or a locking hook. The second locking element can be configured as a locking edge or a locking opening.

[0025] According to an advantageous design of the invention, the terminal block has a release element disposed on one, several, or all retaining elements, with a release section. When the conductor to be clamped applies an actuating force to the release section, the clamping leg held in the retaining element in the open position can be released from the retaining element by the release element. This allows the clamping leg to be automatically released from the retaining element by inserting the conductor. The release section can be used to release the clamping leg from the retaining element by applying pressure with a separate tool, a component of the terminal block such as an actuating element, or directly via the introduced conductor itself. By means of the release element, the clamping leg held in the retaining element in the open position can be released from the retaining element by applying pressure to the release section in the direction of the conductor introduction of the conductor to be connected. According to the design of the spring-force clamping connector, the release element can be configured as part of the clamping spring, for example, as a release element integrally formed with the clamping spring, or as a separate component.

[0026] According to an advantageous design of the invention, the releasing section of the releasing element can be positioned behind the clamping portion in the wire introduction direction.

[0027] The retaining element can be configured as a separate component, which is, for example, fastened to an insulating housing of the terminal block, a busbar, or other component.

[0028] According to an advantageous design of the invention, in one, several, or all clamping springs, the retaining element and / or releasing element disposed therewith are integrally formed with the clamping spring. This achieves particularly efficient and cost-effective manufacturing of the terminal block components and simple installation in the housing. The clamping spring, together with the retaining element and / or releasing element integrally formed therewith, can be manufactured, for example, as a stamped and bent component.

[0029] According to an advantageous design of the invention, one, several, or all wire clamping connectors are configured as cut-clamping connectors, each having opposing blades forming a clamping gap between them, the clamping gap creating a clamping portion for securely clamping the electrical wires. Therefore, the cut-clamping connectors are arranged in a ring within the housing. This allows for the particularly space-efficient placement of multiple cut-clamping connectors within the housing, which are particularly well-suited for circular mating connectors.

[0030] A clip-on connector, also known as an IDC connector, is configured to provide direct electrical contact with an insulated conductor without prior removal of the insulation. This is achieved by pressing the insulated conductor through opposing blades into the clip gap, which cut through the insulation and establish electrical contact with the inner conductor. The blades can be, for example, forked.

[0031] The terminal block according to the invention allows for the simple and quick connection of multiple electrical wires at the cut-clamp connector without prior stripping of insulation. The electrical wires can be introduced into the housing with their insulation intact and then directly into electrical contact via the cut-clamp technique. Here, for example, all the electrical wires to be connected can be introduced into the housing side-by-side from the same housing side and make electrical contact. Therefore, no further pretreatment of the electrical wires is required, especially no additional cutting or shortening. Consequently, the terminal block can be assembled with electrical wires particularly simply and quickly, without the need to individually and sequentially bend and introduce each electrical wire into the corresponding cut-clamp connector.

[0032] According to an advantageous design of the invention, the clamping gaps of one or more clip-on clamping connectors are oriented radially inward or radially outward and / or axially relative to the annular shape with respect to their longitudinal extension direction, the clip-on clamping connectors being disposed within a housing on said annular shape. Correspondingly, in order to securely clamp the electrical wires at the clip-on clamping connectors, relative movement between the electrical wires and the clip-on clamping connectors is required along the aforementioned radial and / or axial directions relative to the annular shape. This allows for the contact of multiple electrical wires at the clip-on clamping connectors while maintaining a simple design structure for multi-pole terminals.

[0033] The objective mentioned at the beginning is also achieved by an electrical plug connector, particularly a circular plug connector, having at least one terminal block of the type mentioned above. This also allows the previously described advantages to be realized.

[0034] In the context of this invention, the indefinite article "one" is not understood as a numeral. Therefore, if, for example, a component is referred to, this should be interpreted in the sense of "at least one component." As long as the angle is described in degrees, the angle refers to a circle of 360 degrees (360º). Attached Figure Description

[0035] The present invention will now be described in detail with reference to the accompanying drawings and with reference to the embodiments.

[0047] exist Figure 1The terminal block 1 shown has a housing 2, which can be configured, for example, as a substantially cylindrical circular housing. A portion of the housing 2 is divided into a plurality of housing segments 20, for example, fan-shaped. A wire clamping connector 3 is provided in each housing segment 20. The wire clamping connector 3 is arranged in a ring around the center. Furthermore, in each housing segment 20, a wire introduction opening 21 is formed on the wire introduction side of the housing 2, which is used to introduce an electrical wire into the housing 2. The electrical wire can be introduced into the wire clamping connector 3 located in the housing 2 through the wire introduction opening 21 along the wire introduction direction L. The housing segment 20 is closed on the housing side away from the wire introduction side by a closure 22, for example, a plate. Connecting contacts 86 extend through the closure 22, wherein the connecting contacts 86 are electrically connected to the wire clamping connector 3.

[0048] Figure 1 And also Figure 2 The terminal block 1 is shown in an incomplete form, with only a portion of the housing section 20, which is symmetrically arranged in a ring, shown by removing the two front housing sections 20. This reveals the sliding operating element 5 centrally located between the wire clamping connectors 3, and this type of illustration better illustrates the function of the sliding operating element. However, in the complete state of the terminal block 1, the sliding operating element 5 is completely surrounded by the housing section 20 and the wire clamping connectors 3 disposed within the housing section in a ring.

[0049] As can be seen, the wire clamping connector 3 is arranged in a ring around the sliding operating element 5. Specifically, the manual operating surface 50 is located in the central region of the housing 2 between the wire clamping connectors 3, and this manual operating surface is used, for example, by means of a tool such as a screwdriver, to manually operate the sliding operating element 5 in the longitudinal direction of movement V. By manually applying pressure to the manual operating surface 50, the sliding operating element 5 can be displaced in the longitudinal direction of movement V, such as... Figure 2 As shown. Here, the wire clamping connector 3 is manipulated, which will be explained in detail below with reference to other diagrams.

[0050] exist Figure 1 The diagram shows a terminal 1 with an unoperated sliding control element 5, meaning the sliding control element 5 is in its initial position. Figure 2The diagram shows a sliding operating element 5 in a manipulated state, wherein the sliding operating element is displaced downward in the longitudinal movement direction V. It can be seen that the sliding operating element 5 has operating contours 51, 52, and 53 on its radially outer side for each wire clamping connector 3, which allow manipulation of the wire clamping connector 3 respectively disposed on the operating contours 51, 52, and 53. The operating contours 51, 52, and 53 extend from the side facing the manual operating surface 50 as a first segment 51, which extends parallel to the longitudinal movement direction V. A second segment 52 is connected to the first segment 51, which extends at an angle in the longitudinal movement direction V. A third segment 53 is connected to the second segment 52, which also extends parallel to the longitudinal movement direction V. Between the operating profiles 51, 52, and 53 of the corresponding wire clamping connectors 3, the sliding operating element 5 has a star-shaped guide tab 54, by means of which the sliding operating element 5 is guided in the slit-shaped receiving portion 23 of the housing 2 along the longitudinal direction of movement V. Furthermore, the guide tab 54 and the slit-shaped receiving portion 23 prevent undesirable torsion of the operating element 5 about its longitudinal axis.

[0051] According to the following Figures 3 to 8 In the described embodiments, the wire clamping connectors 3 are respectively configured as spring-force clamping connectors, each having a clamping spring 4 and a busbar 30. The clamping spring 4 can be configured, for example, as shown in the figure, as a cage-type tension spring, or as a clamping spring formed in other ways. First, an exemplary description of how to construct a clamping spring 4 configured as a cage-type tension spring will be given, as in... Figure 9 As shown in the image.

[0052] according to Figure 9 The clamping spring 4 has a clamping leg 44, and a spring bow 43 is connected to the clamping leg. The support leg 40 can be connected directly or via other elements 41, 42 at the spring bow 43. For example, the support leg 40 can be connected to the spring bow 43 via an arcuate section 41 and a connecting section 42. Figure 3 As can be seen, the support leg 40 is used to support the clamping spring, for example, at the busbar 30.

[0053] The clamping spring 4 has a window-like opening 45 in the clamping leg 44, which is closed by the clamping section 46 towards the free end of the clamping leg 44. Here, the support leg 40 extends through the window-like opening 45 with a tongue 47. The busbar 30 then again... Figure 3 As can be seen, the window-shaped opening 45 also passes through the area between the tongue 47 and the clamping section 46. The clamping part for the electrical conductor is located within the window-shaped opening 45, between the side of the busbar 30 pointing towards the clamping section 46 and the clamping edge of the clamping section 46 pointing towards the busbar 30.

[0054] like Figure 3 It is also shown that the connecting contact 86 can be guided from each wire clamping connector 3 through the enclosure 22 and extend from the housing 2. The connecting contact 86 can be configured as a soldering connector for soldering to a printed circuit board, as a plug connector for inserting into a mating connector, or as other electrical connectors. If the connecting contact 86 is configured as a plug connector, the terminal block 1 can also be configured as a plug connector in the same manner, especially as a circular plug connector.

[0055] exist Figure 3 In the middle, terminal 1 is also like Figure 1 The diagram shows the clamping leg 44 in its unoperated state. Correspondingly, the clamping leg 44 of the clamping spring 4 has not yet been deflected by the sliding actuating element 5. If the sliding actuating element 5 is now moved in the longitudinal movement direction V, the ramp-shaped second section 52 causes the clamping leg 44 to deflect in the radially outward direction, as shown. Figure 4 As shown. If then as Figure 4 Similarly, it is shown that when the sliding element 5 is in the position where the first segment 51 abuts against the corresponding clamping spring 4, the clamping spring 4 does not generate a restoring force on the sliding element 5, so that the sliding element 5 remains in the operating position even without manual operation. The clamping part is now open, allowing the wire to be placed there without force consumption. If the sliding element 5 moves back to the position as shown, the clamping part is now open, allowing the wire to be placed there without force consumption. Figure 3 In the original initial position shown, the clamping spring 4 springs back and securely clamps the electrical wires at the clamping points. The resetting movement of the sliding operating element 5 can be caused, for example, by manually pressing on the surface 55 of the sliding operating element 5 opposite to the manual operating surface 50.

[0056] according to Figure 5 and Figure 6 The implementation of the terminal block 1 is described, wherein each wire clamping connector 3 has a retaining element 6 for holding the clamping leg 44 in the open position. As can be seen, the sliding actuating element 5 can be designed in this case to have no first segment 51 with actuating contours 51, 52, 53, that is, the sloping second segment 52 can extend further upward to the area of ​​the actuating surface 50.

[0057] The retaining element 6 provided with the corresponding clamping spring 4 can be configured as a locking element, for example, by providing the retaining element 6 at the busbar 30 or forming it with it, or by providing it at another part of the terminal block, for example, at the housing 2. Figure 5 This indicates that terminal 1 is in an inactive state. Figure 6In this configuration, terminal 1 is operated by sliding operating element 5. The clamping legs 44 of clamping spring 4 are now held at retaining elements 6 respectively disposed on the clamping legs. In this state, sliding operating element 5 is essentially unloaded by the force of clamping spring 4.

[0058] To release the locking of the clamping legs 44 at the corresponding retaining elements 6, the terminal block 1 can have one or more release elements 7, such as manually operable release elements 7. The terminal block 1 can have a release element 7 for each wire clamping connector 3. A smaller number of release elements 7 can also be present, wherein the release elements can then be individually configured to release multiple clamping legs 44. By manually loading the release element 7, for example by radially inward pressing, the locking of the clamping legs 44 at the retaining elements 6 can be released. This causes the clamping spring 4 to spring back, allowing the previously introduced electrical wire to be securely clamped.

[0059] Figure 7 and Figure 8 An embodiment of terminal block 1 is shown, wherein, as previously described, Figure 5 and Figure 6 As described above, there are corresponding retaining elements 6 for holding the corresponding clamping legs 6 in the open position. The retaining elements 6 can be configured as described above. Here, according to... Figure 7 and Figure 8 The terminal block 1 is configured for automatic wiring, with an automatic release element 7 for each wire clamping connector 3, the automatic release element having a release section 70 and an operating section 71. The release section 70 is positioned such that it can be subjected to force by the inserted wire. By applying the force to the release section 70 by the wire, the operating section 71 of the release element 7 is automatically operated, transmitting the release force to the clamping leg 44 to release the clamping leg from the holding element 6. The release element 7 can be configured, for example, like a pivotable seesaw, which automatically pivots by the operating force applied to the release section 70 by the wire, thereby releasing the clamping leg 44 from the holding element 6 via the operating section 71 that is driven thereto.

[0060] In addition, according to Figure 7 and Figure 8 The terminal 1, especially in terms of operation via the sliding operating element 5, is consistent with... Figure 5 and Figure 6 The wiring terminals are similarly constructed.

[0061] The terminal 1, which has a wire clamping connector in the form of a spring-loaded clamping connector, has been described with reference to the foregoing diagram. The terminal 1 may have a wire clamping connector in the form of a clip-on clamping connector 8, either wholly or partially, which may be disposed in the housing in a manner similar to that of the clamping spring 4. Then, by means of the operating element 5, the movement of the corresponding clip-on clamping connector 8 and / or the wire to be connected can be actuated, thereby clamping the wire at the clip-on clamping connector 8.

[0062] Figure 10 A clip-on clamping connector 8 for terminal 1 is shown. In this embodiment, the clip-on clamping connector 8 is configured as a one-piece curved metal member. The clip-on clamping connector 8 has a base section 87 from which two separate arms 81, 82 branch off adjacent to each other. At each arm 81, 82, a blade 83 is constructed in the clipping region, wherein a clipping gap 80 is formed between the opposing blades 83. The blades 83 end toward their free ends in a V-shaped clipping inlet section 84 extending at an inclination toward the clipping gap 80. The conductor can be introduced into the clipping gap 80 with its insulating sheath. Here, the insulator is first separated between the V-shaped clipping inlet sections 84 and the conductive core of the conductor located inside is exposed and clamped between the blades 83.

[0063] Arms 81 and 82 are separated from each other by a separation gap 85 formed therebetween. The separation gap 85 transitions into a cutting clamp gap 80. At the end region facing away from the cutting edge 83, the cutting clamp connector 8 has a connecting contact 86, such as a pin contact, at the base 87. The cutting clamp connector 8 can be secured in the housing 2 by means of the connecting contact 86 and / or the base 87.
