Description

Technical Field

[0001] This invention relates to a high-voltage electrical circuit board plug-in contact device for an electrical circuit board of an electrical entity. The invention also relates to an electrical circuit board connection for an electrical entity of a vehicle, particularly a power-to-electrical circuit board connection, and to an electrical entity, particularly a circuit board or auxiliary assembly for a vehicle with mounted components. Background Technology

[0002] In the electrical field (electronics, electrical engineering, electrical appliances, power technology, etc.), a large number of electrical connector devices or connector assemblies, sockets, pins, and / or hybrid connectors, hereinafter referred to as (electrical) connectors (also known as mating connectors), are known for transmitting current, voltage, signals, and / or data at a wide range of current, voltage, frequency, and / or data rates. In low, medium, or high voltage and / or current applications, particularly in the automotive field, such connectors must ensure the permanent, repetitive, and / or short-term transmission of power, signals, and / or data after relatively long periods of inactivity in environments subjected to mechanical stress, warmth, potentially high temperatures, contamination, humidity, and / or chemical corrosion. Due to their wide range of applications, numerous specially designed connectors are known.

[0003] Such connectors, and, where applicable, their associated (e.g., in the case of connector devices or connector assemblies) or higher-level housings (e.g., in the case of connector assemblies), can be fitted to wires, cables, cable bundles, etc. (hereinafter referred to as assembled (electrical) cables (also known as electrical entities)) or fitted to (electrical) electrical, electro-optical or electronic components or corresponding assemblies of electrical entities, such as fitted to housings, fitted to lead frames, fitted to circuit boards, etc.

[0004] If a connector (with or without a housing) is located on a cable, wire, or cable bundle, it is also called a floating (mating) connector or plug, socket, or coupling; if it is located on or within an electrical, optoelectronic, or electronic component, assembly, etc., it is also called a connector assembly, such as a (built-in / mounted) connector, (built-in / mounted) plug, or (built-in / mounted) socket. Connectors on such assemblies are also frequently referred to as (plug) receptacles, pin connectors, pin straps, or connectors. - In the context of electrical engineering (generating, converting, storing, and transmitting high-voltage currents in a power grid, preferably three-phase high-voltage transmission), this refers to cable fittings because of their relatively complex structure.

[0005] Such connectors must ensure the proper transmission of electricity, wherein corresponding and partially complementary connectors (connector and mating connector) typically have locking and / or fastening devices for permanently but generally releasably locking and / or fastening the connector to / into the mating connector, and vice versa. - Electrical connection devices for connectors, for example, include or at least have: actual contact devices (usually formed in one piece or integrally in terms of material, such as (crimped) contact elements, etc.; also referred to as terminals) or contact devices (usually formed in one piece from several or two parts, or formed in one piece in terms of material, such as (crimped) contact devices; also referred to as terminals), which must also be securely held therein.

[0006] Efforts have been made to improve electrical connectors and their terminals, particularly to design them more efficiently and manufacture and / or produce them at a lower cost. In the case of vehicles—motor vehicles (rail vehicles), rail vehicles, ships, and aircraft with or without electric traction motors—strict safety requirements must be met for high-voltage and / or high-current connectors, such as for auxiliary components of said vehicles. Depending on the application, these safety requirements involve clearance distances and creepage distances, vibration requirements, etc. The object of this invention is to provide an electrical circuit board mating contact device that meets stringent requirements regarding clearance distances, creepage distances, and potential vibration. Summary of the Invention

[0007] The object of the present invention is achieved by an electrical high-voltage circuit board plug-in contact device (hereinafter referred to as the circuit board plug-in contact device) for an electrical circuit board of an electrical entity; by an electrical, particularly power-electrical, circuit board connection for an electrical entity of a vehicle; and by an electrical entity, particularly for a vehicle, a circuit board or auxiliary assembly with mounted components. - Advantageous developments, additional features and / or advantages of the invention can be found in the following description.

[0008] The circuit board plug-in contact device according to the invention includes an electrical circuit board contact device (preferably one of exactly two terminals) and an electrical plug-in contact device formed separately therefrom (again preferably one of exactly two terminals), wherein, in the circuit board plug-in contact device, the plug-in contact device is arranged laterally offset relative to the circuit board contact device, and provides a conductive connection between the circuit board contact device and the plug-in contact device.

[0009] In other words, apart from the possible multi-component structure of circuit board contact devices and / or mating contact devices, circuit board mating contact devices are at least or exactly two-piece designs, wherein these two “pieces,” namely the circuit board mating contact device and the mating contact device, are combined to form the circuit board mating contact device (see below). - Here, circuit board contact devices and / or mating contact devices, especially mating contact devices (in this case, mating contact devices), can also be two-piece or multi-piece designs.

[0010] Circuit board contacts can be, in particular, in the form of mechanical-electrical circuit board contacts. Mating contacts can be, in particular, in the form of electromechanical mating contacts. Here, "mechanical-electrical" means that circuit board contacts, in addition to their important electrical functions, also possess substantial mechanical functions. Furthermore, "electromechanical" here means that mating contacts, in addition to their important mechanical functions, also possess primary electrical functions.

[0011] The necessary electrical and mechanical functional parts of the circuit board contact device can extend in the longitudinal direction of the circuit board contact device. The necessary electrical and mechanical functional parts of the mating contact device can extend in the longitudinal direction of the mating contact device. The longitudinal directions of the functional parts of the circuit board contact device and the mating contact device can be arranged substantially parallel or at an angle in the circuit board mating contact device.

[0012] The longitudinal direction of the circuit board mating contact device can be substantially parallel to the longitudinal range of the circuit board contact device and the mating contact device. In this case, the common longitudinal direction configured in this way can be the mating connection direction of the circuit board mating contact device or the mating contact device toward the mating contact device, and / or the mating contact device toward the mating contact device or the circuit board mating contact device. In this case, the longitudinal direction can protrude substantially vertically, particularly substantially vertically from the flat area of ​​the circuit board.

[0013] The longitudinal extent of the circuit board contact and the mating contact can only partially overlap in the circuit board mating contact device. Here, the circuit board contact can protrude further away from the circuit board mating contact device in the longitudinal direction than the mating contact (on one side of the circuit board, figure: lower side). Furthermore, the mating contact can also protrude further away from the circuit board mating contact device in the (different) longitudinal direction than the circuit board contact (on one side of the mating contact, figure: upper side). – The free longitudinal end portion of the mating contact can be conductively disposed on the central portion of the circuit board contact.

[0014] The circuit board plug-in contact device may further include an electrically insulated plug-in housing, which is plugged into or can be plugged into the circuit board contact device and the plug-in contact device. Here, the plug-in housing is specifically formed such that the plug-in contact device can engage with the electrically mating contact device via the mating surface of the circuit board plug-in contact device. The plug-in housing may be formed such that it is locked onto or can be locked onto the circuit board contact device. Furthermore, the plug-in contact device is locked within or can be locked within the plug-in housing. Additionally, the plug-in housing may be supported on the circuit board. The plug-in housing may have an insertion bevel for mating contact devices on / in the mating surface.

[0015] Circuit board contact devices may include at least one electrical circuit board terminal for a circuit board, electrical plug-in contact device terminals for plugging in contact devices, and / or mechanical connection devices for plugging in housings. - Electrical circuit board terminals may be, for example, active and / or passive circuit board terminals. Here, at least one push-in pin or push-in lever (multi-spring, actuating pin, pin eye, etc.), soldered pins, SMD pins, (channel) cutouts, etc., may be considered. Electrical plug-in contact device terminals may have, for example, contact shapes, contact areas, contact pads, etc. Here, plug-in contact device terminals may be formed in a manner complementary to the contact device terminal portion of the plug-in contact device. Mechanical connection devices may have, for example, lugs, pins, recesses, etc., and may include at least one latching device.

[0016] The mating contact device may include electrical contact device terminals, mechanical-electrical transition portions, and / or electrically mating contact terminals. Electrical contact device terminals may have, for example, contact shapes, contact areas, contact pads, etc. Here, the contact device terminals may be formed in a complementary manner to the mating contact device terminal portion of the circuit board mating contact device. The mechanical-electrical transition portion may have, for example, spring arms, damping vibration arms, rigid arms, etc. For buffering and / or damping purposes, a transition portion design that is more flexible than other parts of the circuit board mating contact device may be used specifically. The electrically mating contact terminal may have, for example, sockets, tabs, or pins.

[0017] Circuit board contact devices can be in the form of busbars. A busbar is understood to represent, for example, a conductor rail, conductor strip, or conductor support, which can be, for example, further in the form of a (shaped) lead frame. Here, the busbar can be a straight or angled design. The busbar can have a large number of individual electrical circuit board terminals as circuit board terminals. Specifically, the busbar can have at least or exactly two, three, four, five, six, or more individual circuit board terminals. The busbar can have a substantially continuous electrical strip as plug-in contact device terminals. Furthermore, the busbar can have exactly one, two, three, or more lugs as connecting devices.

[0018] The plug-in contact device can be in the form of a socket contact device. A socket contact device may have, in particular, bent electrical contact lugs as contact device terminals. Furthermore, a socket contact device may have a mechanical-electrical spring arm for damping vibrations as a transition section. Additionally, a socket contact device may have an electrical socket as a mating contact terminal.

[0019] Circuit board contact devices or busbars can be substantially or primarily I-shaped, L-shaped, or U-shaped. Here, the limbs of an L-shaped busbar can have the same or different lengths. Plug-in contact devices or socket contact devices can be substantially or approximately Z-shaped or L-shaped. Here, the shape of the plug-in contact device or socket contact device can be a stretched and / or elongated Z-shaped design or a stretched and / or elongated L-shaped design.

[0020] The circuit board plug-in contact device may have a generally L-shaped busbar and a slender, generally Z-shaped socket contact device. Here, the contact device terminal and the mating contact terminal form two free limbs, and the transition portion forms a connecting web between the two slender, approximately Z-shaped free limbs of the socket contact device.

[0021] The plug-in contact can be disposed on a single limb of the L-shaped busbar via its contact device terminals. Here, the contact device terminals are disposed on the plug-in contact terminals of the L-shaped busbar. Here, the plug-in contact is arranged in the internal space of the circuit board plug-in contact device, which is partially defined by the L-shaped busbar. In particular, the plug-in contact protrudes inward from the limb of the L-shaped busbar into the internal space of the circuit board plug-in contact device, which is partially defined by the L-shaped busbar.

[0022] The circuit board insertion contact device can preferably meet the specified vibration requirements according to LV 214, or according to vibration requirements of severity level 1, 2, 3 and / or 4. In particular, the circuit board insertion contact device meets the specified vibration requirements or vibration requirements of severity level 2 or 3. Furthermore, preferably according to LV 214, the circuit board insertion contact device may not meet the specified requirements or requirements of severity level 4 and / or higher.

[0023] Circuit board mating contacts can be designed for voltages of at least approximately 60 V, 100 V, 150 V, 250 V, 500 V, 800 V, 1 kV, 1.25 kV, or 1.5 kV, and / or at least approximately 10 A, 20 A, 30 A, 45 A, 60 A, 75 A, 100 A, 125 A, 150 A, 200 A, 250 A, 300 A, or 400 A. Circuit board mating contacts can also be designed for voltages below 250 V and / or currents below 10 V. Circuit board mating contacts are preferably designed for temperatures ranging from approximately -40°C to approximately 120°C, 140°C, 150°C, 160°C, 170°C, 180°C, 190°C, or 200°C.

[0024] Circuit board contacts, plug-in contacts, and / or plug-in housings can be integrally formed. - An integral design is understood to refer to a design of the contacts of a plug-in housing in which there is only one single component, which can only be separated by destruction. The component (part) is made from a single original part (metal plate, blank, etc.) and / or from a single original material (molten metal, molten plastic), which, in itself, is necessarily an integral part. Internal bonding is formed through adhesion and / or cohesive forces. Coatings, depositions, electroplating, etc., can also be applied here (for circuit board contacts and plug-in contacts).

[0025] Contact devices, including circuit board contacts and plug-in contacts, can be formed as a single piece of material or inseparably formed as a single piece. - A (adhesive) single-piece design on the material is understood to refer to a design of a contact device (including components of circuit board contacts and plug-in contacts) in which its individual parts are fixed to each other material-to-material (welding, brazing, adhesive bonding, etc.), and it, that is, the contact device, preferably cannot be separated into its individual parts without damage. In this case, bonding can also be achieved by non-forced and / or forced locking connections (not in the case of an integral design).

[0026] An inseparable single-piece design is understood to refer to a design of a contact device (including components of circuit board contacts and plug-in contacts) in which its individual parts are secured to each other by non-forced and / or forced locking, and it, that is, the contact device, preferably cannot be separated into its individual parts again without damage. (In the case of a multi-part design, there must be no non-forced and / or forced locking connection, or in this case, the connection must be established by a third part).

[0027] A circuit board plug-in contact device, including its contact elements (circuit board contacts and plug-in contacts) and its plug-in housing, can be separably configured as a single piece. - A separable single-piece design is understood to mean a design of a circuit board plug-in contact device (on one hand, the contact elements (including components of the circuit board contacts and plug-in contacts), and on the other hand, the plug-in housing as a component), wherein it can be separated manually or with the aid of tools without damaging its two components (contact elements and plug-in housing). Circuit board plug-in contacts are preferably coupled via non-forced and / or forced locking connections.

[0028] The circuit board connection according to the invention includes a circuit board and at least two electrical circuit board plug-in contacts mounted on the circuit board, wherein at least one circuit board plug-in contact is formed according to the invention.

[0029] Furthermore, the circuit board mating contact device is mounted on the circuit board in such a manner that the minimum linear distance (creep distance) between the circuit board contact devices on the circuit board is greater than the minimum linear distance (gap distance) between the mating contacts above the circuit board. If at least one mating housing exists, it is not included in the distances mentioned above.

[0030] On a circuit board, two internal spaces of a circuit board mating contact device can face each other, and these internal spaces are partially defined by circuit board contact devices that are preferably substantially L-shaped. The mating contacts of the circuit board mating contact device under discussion are preferably arranged in such internal spaces. Furthermore, on the circuit board, the total internal space partially defined by the two substantially L-shaped circuit board contact devices can have a substantially rectangular occupies an area. Additionally, on the circuit board, the mating contacts of the circuit board mating contact device can be arranged in the circuit board connection from opposite sides of the circuit board connection.

[0031] This invention provides a mechanically pluggable circuit board connection with an adaptable arrangement of circuit board plug-in contacts on the circuit board. The circuit board plug-in contacts can be used to mate contact devices at different intervals and / or orientations. In particular, due to the plug-in housing, a much larger creepage distance and a larger clearance distance are generated on the circuit board itself compared to the prior art. The circuit board plug-in contacts, due to their design, can easily absorb vibrations, especially micro-vibrations (spring arms).

[0032] The beveled surface on the mating housing of the circuit board plug-in contact device allows for handling larger tolerances. Users of the circuit board plug-in contact device can install pin strips (connectors) of proven and known contact systems after pre-installed circuit boards. Circuit board contacts in the form of busbars (conductive rails, conductive strips, conductive pillars, lead frames) with their own circuit board terminals or individual circuit board terminals can be easily fabricated from pre-molded strips. Plug-in contacts can be electromechanically connected to the circuit board plug-in contact device in various ways (soldering, brazing, adhesive bonding, riveting, snap-fit, etc.).

[0033] The plug-in contact device can be selected from a large number of contact systems (MCP, MCON, MQS, etc.), which can include corresponding terminals on the mating contact side. The busbar preferably has multiple springs or soldered pins as its circuit board side terminals. The busbar can be straight or angled, particularly at an angle of approximately 90°. The material thickness of the busbar can be selected according to the application, for example, less than, approximately, or greater than: 0.4 mm; 0.5 mm; 0.6 mm; 0.8 mm; 1.0 mm; 1.2 mm; 1.4 mm; 1.5 mm, etc.

[0034] The electrical entity according to the invention includes an electrical circuit board and electrical circuit board mating contacts thereon as connector devices, or an electrical device and a power-electrical circuit board connection, wherein the circuit board mating contacts or circuit board connection are formed according to the invention. Here, the circuit board may also be referred to as a substrate. Such an entity may take the form of, for example, an electrical component, electrical part, electrical module, electrical unit, electrical instrument, electrical equipment, electrical facility, electrical system, etc.

[0035] The invention will now be explained in more detail with reference to the accompanying drawings, which are schematic and not drawn to scale. Parts, elements, components, units, parts, and / or patterns having the same, unique, or similar configurations and / or functions are identified by the same reference numerals in the description of the drawings (see below), the list of reference numerals, the patent claims, and the drawings (figures). Any alternatives not explained in the description of the invention (see above), not shown in the drawings, and / or not definitively identified, static and / or dynamic reversals, combinations, etc., or components, patterns, units, components, elements, or portions thereof with respect to exemplary embodiments of the invention, may be further collected from the list of reference numerals and / or the description of the drawings.

[0036] In the context of this invention, features (parts, elements, components, units, parts, functions, variables, etc.) can be positively configured, i.e., present, or negatively configured, i.e., absent. In the application materials (specification (description of the invention (see above), description of the drawings (see below)), list of reference numerals, claims, drawings), if the absence of a negative feature according to the invention does not assign value, then that negative feature is not explicitly interpreted as a feature. That is, the actual completed invention, and not constructed using prior art, includes the omission of said features.

[0037] The features of this application material can be used not only in the specified manner and / or method, but also in another manner and / or method (isolation, combination, substitution, addition, independence, omission, etc.). In particular, features in the patent claims and / or description can be replaced, added, or omitted based on the reference numerals and the features assigned to them, and vice versa. Furthermore, as a result, the features in the patent claims can be explained and / or described in more detail.

[0038] The features in the specification can also be interpreted as optional features (given the prior art, which was initially largely unknown); that is, each feature can be considered optional, arbitrary, or preferred, i.e., not mandatory. Therefore, features (possibly including their peripheries) can be isolated from exemplary embodiments, and then said features can be transferred to a generalized inventive concept. In exemplary embodiments, no feature (negative feature) indicates that the feature is optional for the invention. Furthermore, in the case of typological terms for features, genus terms for features can also be implicitly understood (possibly further subdivided into subgenus, etc.), resulting in the possibility of generalization of features, for example, considering equivalence effects and / or equivalence.

[0045] Below is an embodiment of a variation of the electrical high-voltage circuit board or electrical high-voltage substrate plug-in contact device (hereinafter referred to as: circuit board plug-in contact device 10) for the electrical circuit board 1 or electrical substrate of electrical entity 0. Figures 2 to 7 The invention will be explained in more detail by examining exemplary embodiments of two embodiments, namely, the power-circuit board connection 2 of electrical entity 0 and the electrical entity 0.

[0046] The specification "high voltage" is intended to indicate that the circuit board plug-in contact device 10 is designed for at least 60 V (see also above), i.e., for voltages that, depending on the application, may pose a danger to life and limbs from which a risk begins. The electrical entity 0 can be in the form of a circuit board or auxiliary assembly with mounted components, such as a circuit board or auxiliary assembly with mounted components in a vehicle having an internal combustion engine or electric traction motor, for example, an air conditioning compressor, heating module, etc.

[0047] Although the invention has been described and illustrated in more detail through preferred exemplary embodiments, the invention is not limited to the disclosed exemplary embodiments, but has a more fundamental nature.

[0048] Other variations may be derived from and / or from the foregoing description of the invention without departing from the scope of protection of the invention. The invention is generally applicable in the electrical field, for the case of electrical entities (see foregoing). Ground-based electrical engineering forms an exception here. The accompanying drawings only show those spatial portions necessary for understanding the subject matter of the invention. Names such as connector and mating connector, terminal and mating terminal, etc., should be interpreted synonymously, that is, they can be used interchangeably. - The explanation of the invention based on the accompanying drawings below refers to the longitudinal direction Lr (an alternative to the mating connection direction Sr), the lateral direction Qr, and the vertical direction Hr of the circuit board mating contact device 10 according to the invention.

[0049] The object within the scope of this invention is: electrical high-voltage mating contact device 20 (i.e., high-current mating contact device 20, hereinafter referred to as mating contact device 20) for various electrical connectors 5 (e.g., pin strips 5 or connectors 5) with different spacing and orientations, such as tab contact device 20 (see Figure 2 How to establish an internal electrical connection with the electrical circuit board 1 of the electrical entity, while increasing the creepage distance on the electrical circuit board 1?

[0050] Existing technology Figure 1 The figure illustrates a power-to-circuit board connection 2 with two electrical high-voltage circuit board socket contacts 90, according to the prior art. In the figure, arrows represent gap distance and creepage distance; in the prior art, the gap distance (dashed arrow) and creepage distance (solid arrow) are substantially the same. In particular, the relatively short creepage distance compared to the gap distance is a problem in high-voltage applications. The creepage distance should always be longer than the gap distance, and the difference should be as large as possible.

[0051] The solution according to the invention involves electrically connecting (e.g., soldering or riveting) a circuit board contact 100, which serves as a terminal of a circuit board plug-in contact device 10, to a plug-in contact 200, which also serves as a terminal of the circuit board plug-in contact device 10, and arranging them in a laterally offset manner within the circuit board plug-in contact device 10. Due to this geometric arrangement between the circuit board contact 100 and the plug-in contact 200, two pluggable circuit board connections serving as power-to-circuit board connections 2 can be flexibly arranged on the electrical circuit board 1, and thus the minimum creepage distance can be significantly increased (see...). Figure 5 and Figure 6 (The solid arrow in the middle).

[0052] When connector 5 is mounted on this circuit board connection 2, its electrical mating contact 20 must not be bent in order to maintain creepage distance on the electrical circuit board 1. As a result, smaller tolerances can be achieved, and mounting connector 5 on an electrical entity 0 having the circuit board connection 2 according to the invention is quite easy. Furthermore, the invention provides new design freedom and greater flexibility.

[0053] Preferably, see Figures 2 to 7 The circuit board contact 100 is in the form of a busbar, and the plug-in contact 200 is in the form of a socket contact. Of course, other contact devices can be used. These terms are used in the following text; however, the terms circuit board contact 100 instead of busbar and plug-in contact 200 instead of socket contact are always implicitly understood to be applicable.

[0054] As a busbar, the electrical or mechanical-electrical (see above) circuit board contact device 100 starts from the side of the electrical circuit board 1 in its longitudinal direction Lr 100 (Preferably parallel to the longitudinal direction Lr of the circuit board plug-in contact device 10) preferably includes three functional parts: an electrical circuit board terminal 110 for electrical contact with the electrical circuit board 1, an electrical plug-in contact device terminal 120 for electrical contact with the socket contact device 200 (through its electrical contact device terminal 220), and a mechanical connection device 130 for the electrically insulating plug-in housing 300 of the circuit board plug-in contact device 10.

[0055] In this example (busbar), the electrical circuit board terminals 110 include multiple, particularly two, four, or six push-in pins or push-in rods; the electrical plug-in contact terminal 120 includes a substantially continuous electrical strip; and the mechanical connection device 130 includes multiple, particularly one or two mechanical lugs. Other designs of the relevant functional parts of the busbar are mentioned in the description of the invention.

[0056] In a plane stretched, for example, by a vertical direction Hr and a transverse direction Qr, the busbar has an L-shaped profile with limbs of substantially equal length (i.e., a V-shaped profile with a 90° mid-angle); needless to say, the limbs can also be formed with different lengths and / or the busbar can have different profiles (see above). The busbar is preferably formed such that half of the busbar extending in the longitudinal direction Lr and the transverse direction Qr can be symmetrically folded or rotated (rotationally symmetrical) onto the other half of the busbar also extending in the longitudinal direction Lr and the transverse direction Qr (see, for example, see...). Figure 3 (Preferably 90° rotational symmetry).

[0057] Electrical or electromechanical (see above) plug-in contact 200, which serves as a socket contact device, extends longitudinally from the side of the electrical circuit board 1 along its longitudinal direction Lr 200 (Preferably parallel to the longitudinal direction Lr of the circuit board plug-in contact device 10) It also preferably has three functional parts: an electrical contact device terminal 220 for the electrical contact busbar (through which it plugs into the contact device terminal 120), a mechanical-electrical transition portion 230, and an electrical mating contact terminal 240 for the electrical contact mating contact device 20.

[0058] In this example (socket contact device), the electrical contact device terminal 220 includes, in particular, bent electrical contact lugs, the mechanical-electrical transition portion 230 includes a spring arm for damping vibrations, and the electrically mating contact terminal 240 includes a socket. Other designs of related functional portions of the plug-in contact device 200 are mentioned in the description of the invention.

[0059] In a plane stretched, for example, by the longitudinal direction Lr and the transverse direction Qr, the socket contact device has an elongated, approximately Z-shaped profile (see, for example, [reference needed]). Figure 3 In this case, the connecting web between the two free limbs of the Z-shaped profile is formed by a spring arm for damping vibrations, the shorter contact lug is arranged on one free limb (Z-shaped profile) or its longitudinal end portion, and the longer socket in the socket contact device is arranged on the other free limb (Z-shaped profile) or its longitudinal end portion.

[0060] In this case, the longitudinal direction Lr of the busbar 100 Preferably, it is formed by the main extending direction of its press-in pin or press-in rod and its mechanical lug. In this case, the longitudinal direction Lr of the socket contact device 200 Preferably, it is formed by the main extension direction of its socket. In this example, the busbar and its longitudinal direction Lr 100 and socket contact devices and their longitudinal direction Lr 200 Arranged substantially parallel within the circuit board insertion contact device 10 (see...) Figure 2 and Figure 4 However, in other embodiments, this can be at an angle.

[0061] Furthermore, the busbar and socket contact device are configured as a circuit board plug-in contact device 10 such that, relative to the central portion of the circuit board plug-in contact device 10, which is composed of the busbar and socket contact device 200, at one end, the electrical circuit board terminal 110 protrudes further in a longitudinal direction Lr, while at the other end, the mating contact terminal 240 protrudes further in another longitudinal direction Lr.

[0062] The socket contact device is electrically and mechanically fixed to the plug contact device terminal of the busbar via its electrical contact device terminal 220. Specifically, bent electrical contact lugs are fixed to the electrical strip, which can be achieved by welding, brazing, or riveting (conductive connection 12). From here, the transition portion 230, or the spring arm for damping vibrations, extends away from the longitudinal range of the busbar at angles different from 0° and 90° (see...).
