The DE 697 28 548 T2 discloses an electrical printed circuit board angle terminal with a printed circuit board connection section designed as an eyelet and a counter terminal contact section designed as a fork, which are aligned at right angles to one another in the angle terminal over a bending region of the angle terminal. In an inner corner area of the bending area, the bending area is provided with a notch in order to simplify the formation of the right-angled bending area.

The DE 10 2012 102 904 A1 teaches an angle terminal designed as an electrical contact pin with two connection sections, the respective connection section having a square cross section. A bending area is set up in the angle terminal between the two connection sections, via which the connection sections can be set up at a right angle to one another in the angle terminal. For this purpose, the bending area has a circular cross section.

The DE 10 2009 026 816 A1 discloses a connection element for the electrical connection of two components, with two electrical contact elements and a tolerance compensation element. The connection element is integrally formed, the first contact element and the second contact element being connected to one another via the tolerance compensation element, and the tolerance compensation element enabling length compensation in at least one spatial direction in order to specify a desired spatial positioning of the first contact element and the second contact element relative to one another.

The WO 2011/015 445 A1 teaches a cut-optimized electrical contact means, comprising a contact strip having a substantially constant thickness, the contact strip having at least one twist by an angle of rotation and at least one bend by an angle of bending. At its longitudinal end sections, the contact means has electrical contacts formed from the contact strip.

The WO 2018/052 888 A1 discloses an L-shaped printed circuit board terminal with a printed circuit board connection section in the form of an eyelet and a counter terminal contact section in the form of a pin, which are aligned at right angles to one another in the terminal over a bending region of the terminal. The counter terminal contact section also has an S-shaped bending area, which lifts an actual contact section from its electrical connections to the connection section.

In conventional stamping of printed circuit board angle terminals, the design of the angle terminals means that the design is different (cf. 1 ) a large proportion of punching waste. This results in high tool costs and low OTE (Overall Tool Effectiveness). Furthermore, the coating speed is comparatively slow, and the consumption of coating materials (in particular high-quality materials such as gold or silver) is comparatively high due to the angled shape. When such angle terminals are wound up, winding damage can occur comparatively quickly and / or transport damage can occur comparatively frequently. Furthermore, there is a recurring occurrence of dimensional deviations and / or manufacturing deviations (geometry errors) due to the manufacture.

Efforts are constantly underway to improve electrical connector devices or connectors, in particular to make them more robust and to design and / or manufacture them more cost-effectively. It is therefore an object of the invention to provide an improved printed circuit board angle terminal for a printed circuit board, preferably for the motor vehicle sector. Here, the angle terminal should be simple and / or easy to use, and its manufacture and assembly should be simple and inexpensive. Furthermore, when the angular terminal is punched, less punching waste is to be obtained with respect to an angle terminal from the prior art and / or the angle terminal should be able to be produced with fewer geometry errors.

The object of the invention is by means of an electrical printed circuit board angle terminal, in particular a printed circuit board angle terminal or a printed circuit board angle tab terminal, preferably for the motor vehicle sector; by a method for producing an electrical printed circuit board angle terminal, in particular a printed circuit board angle terminal or a printed circuit board angle tab terminal, preferably for the motor vehicle sector; and by means of a printed circuit board, a connector, a device, a device, a module, a device, an apparatus, an aggregate, a system or a system; solved according to the independent claims. - Advantageous further developments, additional features and / or advantages of the invention result from the dependent claims and the following description.

A preferred starting point is a substantially square or a substantially rectangular main cross-section of a printed circuit board angle terminal considered below, which z. B. can also be designated as a bending angle terminal or angled circuit board contact device. Furthermore, in the following, such an angle terminal is not to be understood as a terminal, the circuit board connection section and the counter terminal contact section of which are merely offset and / or displaced in parallel. Starting from an angle terminal blank, a (real) pivoting movement and / or a (real) twisting movement (twisting less than 360 °) to an angle terminal assembly has taken place between the connection section and the contact section. It is possible to bend the angle terminal assembly only after it has been installed on a circuit board.

The electrical printed circuit board angle terminal according to the invention has exactly one or at least one (e.g. exactly two or exactly three) printed circuit board connection section for the electromechanical connection of the angled terminal to a printed circuit board (e.g. with a conductor track, a metal tongue, a pad, etc. ), and a counter terminal contact section for the electromechanical connection of the angle terminal to a counter terminal (e.g. on a plug / cable, a second circuit board, etc.). According to the invention, a mechanically bendable bending area is set up at least in sections in the angle terminal between the connection section and the contact section, a cross section of the angle terminal preferably changing in a longitudinal direction of the angle terminal for the bending area, and the bending area comprising a bypass section of the printed circuit board angle terminal and the bypass section itself has a bypass bending zone.

This applies, see below, to both a blank, e.g. B. a punch blank, the angle terminal (controlled bending adjustability of an angle terminal blank) as well as a finished angle terminal for assembly (controlled bending setting of an angle terminal component). In addition to its mechanical function, the bending area naturally also has an electrical function, ie an electromechanical function overall. In this case, the angular terminal assembly can only be attached to / on the printed circuit board, the angular terminal possibly not needing a housing for its electromechanical function. - According to the invention, there is a variable design of an angle terminal for assembling / assembling on a printed circuit board and a high flexibility due to its variable geometry.

The angle terminal itself is e.g. E.g .: as a one-piece, i.e. H. not easily separable or non-positively and / or form-fittingly together; preferably as a one-piece material, i.e. H. cohesively held together and not separable without damaging one of its components; or in particular as an integral, i.e. H. homogeneous in the sense of a single (integral or materially one-piece) piece, e.g. B. a sheet, manufactured, angle terminal formed. - In particular, the angle terminal is punched (shape), the bending angle of the bending area not yet being set up. This setup by means of a bending process, the angle terminal blank becoming an angle terminal component, takes place in a later manufacturing step of the angle terminal apart from its (form) stamping production, in particular after a coating process for the angle terminal blank.

A printed circuit board (PCB: Printed Circuit Board) should also be understood to mean a printed circuit board, a circuit board, a printed circuit, a lead frame, etc. The circuit board may be a carrier for electrical and / or electronic components and is used for mechanical fastening and electrical connection of these components and, if necessary, for mechanical fastening of the electrical circuit realized with the circuit board and, if appropriate, for an electrical connection of this circuit. - In general, the term "printed circuit board" is to be interpreted broadly, i. H. the angle terminal is generally suitable for a z. B. electrically non-conductive substrate such as a plastic housing (defined as a printed circuit board).

By means of the bending area, an angle between the connection section and the contact section can be set or controlled in a controlled manner as a bending angle. According to the invention, the bending angle of the angle terminal can be selected in a controlled manner by means of the bending area. Under 'controls' is supposed to B. mastered, should not be understood unintentionally or validly verifiable. The bending area can be designed as a necessary bendable (angle terminal blank) or a necessary bent (angle terminal assembly) bending area, which is bendable or bent by a bending process, the bending angle not being able to be finally set up or set up by a master molding process.

In embodiments, the bending area can be designed or designed as a pivoting bending area, as a result of which a material layer of the contact section can be pivoted or pivoted in one plane (projection plane, straight projection) relative to a material layer of the connecting section. The plane is not swiveled. Rather, the contact section or its material layer lies opposite the connection section or its material layer in a plane in which the contact section or the connection section also lies (at least in some areas), or in a projection plane in which the contact section or the Connection section (at least in some areas) is pivoted. In embodiments, the bending area can be configured or designed as a twisting bending area, as a result of which a cross section of the contact section can be twisted (twisted) or twisted (twisted) relative to a cross section of the connecting section.

Here, it is preferred to design the bending area as a pure swivel bending area (e.g. first and third embodiment, see below) or as a compound torsional swivel bending area (e.g. second embodiment, see below). - A swivel bending angle (angle in one plane) indicates the angle z. B. a center line of a material layer of the angle terminal in the bending section is pivotable or is pivoted. The angle of twist indicates the angle z. B. a cross section of the angle terminal in the bending section is rotated or twisted. A combination of swivel bending angle and twisting bending angle can of course be used, which leads to a three-dimensional bending angle or a solid angle.

In an angle terminal blank of the angle terminal, the connection section and the contact section can extend essentially along a single straight line or along at least two, essentially parallel straight lines. Furthermore, in an angle terminal assembly of the angle terminal, the bending angle between the connection section and the contact section in a projection plane (straight projection) can have a value different from 180 °. In the case of the angle terminal blank, the connection section and the contact section extend essentially in one plane (sheet metal plane when punching out). And with the angle terminal assembly, the bending angle in the projection plane is approx. 30 °, approx. 45 °, approx. 60 °, approx. 75 °, approx. 90 °, approx. 105 °, approx. 120 ° or approx. 135 °, an approx. 90 ° angle being preferred. Other angles are of course applicable if necessary. A straight overall length of an angled terminal blank can be longer than an angled total length of an angled terminal piece relating to this angled terminal blank.

In embodiments, the bypass section can run away from a direct or shortest connection from the connection section to the contact section in / at the angle terminal. Furthermore, the bypass section can be connected to the connection section via a connection bending zone. Furthermore, the bypass section can be connected to the contact section via a contact bending zone. - This in turn affects both the angle terminal blank and the angle terminal assembly. In the angle terminal blank, the bending zone (s) have not yet been bent in a controlled manner, whereas the bending zone (s) in the angle terminal component have been bent in a controlled manner. A relevant inner or outer corner area of the bypass section, the connecting bending zone and / or the contact bending zone can be angular (preferred) or rounded.

In embodiments, a bypass section can be formed in a / the angled terminal blank as a connecting web between two legs of a mainly (approximately to substantially) U-shaped bending area. Here, a first leg of the u-shaped bending area can have a / the connecting bending zone, the connecting web of the u-shaped bending area can have a / the bypass bending zone and / or a second leg of the u-shaped bending area can have a / the contact bending zone. Analogously to this, an i-shaped, s-shaped or v-shaped bending area can of course also be set up in the blank terminal.

In an angled terminal blank, a boundary of the bending area can be substantially aligned with a boundary of the connection section and / or the contact section. Furthermore, a boundary of the connection section can be substantially aligned with a boundary of the contact section. Furthermore, the bending area can have a meandering course with two, three or four adjoining arms. The bypass section can be set up essentially parallel to the connection bending zone and / or to the contact bending zone in the angle terminal. Furthermore, the connection bending zone can open at an approx. 90 ° angle in the connection section and / or at an approx. 90 ° angle in the bypass section, other angles being of course applicable here. In addition, the contact bending zone can open at an approx. 90 ° angle in the contact section and / or at an approx. 90 ° angle in the bypass section. Other angles in one plane of the angle terminal blank, e.g. B. about 30 °, about 45 °, about 60 °, are of course applicable if necessary.

In an angular terminal assembly, the angular terminal can have a substantially three-dimensional shape. Furthermore, the bending area can be designed as a meandering bend with one, two, three or four bending zones. Furthermore, the bending area can be designed as a bending area running outside or inside between the connection section and the contact section. In addition, the connection section and the contact section can be pivoted and / or rotated relative to one another. Applicable angles are, independently of one another, again in each case: approx. 30 °, approx. 45 °, approx. 60 °, approx. 75 °, approx. 90 °, with the approx. 90 ° angle again being preferred. Of course, other angles can also be used. Furthermore, a longitudinal end section of the connection section can be arranged directly adjacent to a longitudinal end section of the contact section via a gap.

In addition, the bypass section can be folded out of a plane of the connection section and / or the contact section. An approximately 90 ° angle is preferably used here, another angle being applicable, if applicable. The connection bending zone can connect the connection section to the bypass section via an approximately 90 ° angle or an approximately 180 ° angle. Furthermore, the contact bending zone can connect the contact section to the bypass section via an approximately 90 ° angle or an approximately 180 ° angle. Other angles (approx. 30 ° to approx. 180 °) can in turn be set up if necessary. A bending axis for the connection bending zone lies essentially parallel to a center line of the connection section, and / or a bending axis for the contact bending zone lies essentially parallel to a center line of the contact section.

According to the invention, the angle terminal cannot be shaped exclusively by means of a stamping process. Among them, e.g. B. also a die cutting process. The angle terminal can e.g. B. as an angled terminal for soldering (e.g. for a contact system in the soldering area), a solderless angled terminal (e.g. for a contact system in the pressfit area) or an SMD angled terminal (SMD: Surface-Mounted Device, surface-mounted component). Here, the connection section z. B. as a solder pin, a 'multispring', an 'action pin', as an 'eye-of-the-needle' etc. Furthermore, the contact section can be designed as a nano-pinterminal, an MQS-pinterminal (MQS: Micro Quadlok System), a tab terminal, etc. Another contact section and / or another connection section can of course be used. In embodiments, the bending area may be a spring area of the Angle terminals can be formed. Furthermore, the angle terminal can comprise two or more connection sections, each with a bending area. In such a case, the angle terminal is preferably designed as an angle tab terminal. Furthermore, the angle terminal can be manufactured by a manufacturing method according to the invention.

In the method according to the invention for producing an electrical circuit board angle terminal, the angle terminal is formed as an angle terminal blank in a master molding process, preferably a stamping process, a bending region with a bypass section of the angle terminal being formed between a circuit board connection section and a counter terminal contact section of the angle terminal becomes. After the master molding process, the angle terminal blank is coated in an optional coating process, and after the master molding process or after the coating process, the angle terminal blank is formed into an angle terminal assembly in a bending process. In the bending process, the bypass section is first bent out of a plane of the connection section and / or the contact section, and after the bypass section has been bent out, the connection section is pivoted relative to the contact section or vice versa.

In the master molding process, the connection section and the contact section can be formed extending essentially along parallel straight lines in the angle terminal. Such a straight line is e.g. B. defined by a longitudinal center line or an outer boundary line of the connection section or the contact section. The parallel lines can coincide. Through the bending area or the bypass section, an angle is set in a controlled manner as a bending angle between the connection section and the contact section. In addition, in the master molding process, an extension of the bypass section of the angle terminal can be offset, in particular offset parallel, to extend the connecting section and / or the contact section.

In the bending process, the bypass section can first be bent out of a plane of the connection section and / or the contact section. Here, the connection section can be bent out of the plane of the contact section, or the contact section can be bent out of the plane of the connection section. Furthermore, in the bending process, after the bypass section has been bent out, the connection section can be pivoted relative to the contact section or vice versa. Here, a swivel angle in a projection plane (straight projection) between the connection section and the contact section is set in a controlled manner as a bending angle.

Furthermore, in the bending process, after the bypass section has been bent out, the connection section can be rotated relative to the contact section or vice versa. Here, a rotation angle in a projection plane (straight projection) between the connection section and the contact section is set in a controlled manner as a bending angle. In addition, the bending process can be carried out prior to an assembly process / assembly process of a printed circuit board or can be integrated into the assembly process / assembly process of the printed circuit board.

The master molding process can be designed as a pure stamping process or a pure stamping process. That is, the pure punching process is not designed as a shape punching process and / or furthermore does not comprise any other manufacturing process, such as, for example, B. an actual bending process taught here; this is also applicable to the form stamping process. Furthermore, the coating process can be designed as a global coating process or a selective coating process (preferred). In addition, the bending process can be integrated in the master molding process, or the bending process is carried out separately from the master molding process. Furthermore, the angle terminal can be designed as a printed circuit board angle terminal according to the invention.

A printed circuit board according to the invention has at least one electrical printed circuit board angle terminal, the angle terminal being designed according to the invention and / or manufactured according to the invention. Here, the angle terminal can only be attached to / on the circuit board, the angle terminal not requiring a housing for its electromechanical function. A housing can of course also be used. A connector according to the invention has at least one electrical printed circuit board angle terminal, the angle terminal being designed according to the invention and / or manufactured according to the invention, and / or the connector has a printed circuit board according to the invention. The printed circuit board or the connector can have an angle terminal arrangement with a plurality of angle terminals. In this case, the angle terminals of an angle terminal arrangement can all be individually bent and / or be configured at substantially the same angle. Furthermore, the angle terminal, the angle terminal arrangement, the circuit board or the connector can have a housing which supports the function of the angle terminal or the angle terminal arrangement.

According to the invention, variable angle terminals with z. B. meandering bends Realization of variably adjustable bending angles without the aid of complex stamping processes, complex coating processes and / or complex bending processes. Depending on the configuration of an angle terminal or an angle terminal arrangement with a plurality or a plurality of angle terminals, there are a number of main advantages. A stamping process can work significantly more effectively because it can produce a larger number of pieces per unit of time than in comparison with the prior art. The punching tools can, if necessary, continue to be used for other configurations of angle terminals or angle terminal arrangements. The costs (OTE) can be greatly reduced by a selective coating possible by the invention.

Furthermore, the invention results in comparison with the prior art: less punching waste, comparatively low tool costs, comparatively low material costs, a comparatively high coating speed and / or a comparatively low consumption of coating materials. In addition to less punching waste, there is an overall reduction in a strip material during punching (material savings), since there is no pronounced angle in the blank terminal blanks or the angle terminals in the punch layout no longer have to be rotated by 45 ° or 90 °. Damage to the winding and / or later transport damage can be better avoided during winding. A dimensional deviation and / or a manufacturing deviation (geometry errors, angular errors) due to the production can be less than in the prior art.

According to the invention, angle tab terminals with two connection sections or a multistitch zone (two or more than two connection sections) can be used for inserting a 90 ° variant into a printed circuit board. Such a geometry can also be used in an angled terminal. It is possible to replace an eye-of-the-needle connection section with an inexpensive action pin zone as the connection section. Nevertheless, eye-of-the-needle connector sections can be used. A multispring in the rolling direction can be omitted. Furthermore, the bending area can act as a spring area, which can be advantageous when subjected to vibrations. - Of course, according to the invention, angle terminals of any contact system, in particular a contact system in the pressfit and / or soldering area, can be implemented.

Improved stroke rates result in the punching process. The coating process results in faster driving in electroplating. The coating process is significantly simplified, since it is only a "normal geometry", and thus a higher coating speed can be used. The geometry according to the invention allows the connection sections to be bent in the assembly (individual connection section or multistitch zone). That is, alignment of the connection sections or the angle terminals to the printed circuit board is possible in the assemblage through the bending process (setting of wobble circles). The connection sections or the contact sections can be bent at different angles. For applications, an inlay process may no longer be necessary. H. there is no need to build costly inlay handling.

The pivot angle α can appear in the drawing plane as a projection plane, if the angle terminal 2 a course extension in the height direction Mr owns (extension) Mr of the angle terminal 2 ). This is not shown in the drawing.

According to the invention, in a master molding process (step I), in particular a stamping process (step I), first an angle terminal blank 2 manufactured as in the 5 . 7 . 9 and 12 is shown. The angle terminal blank 2 is, apart from a thickness of its material layer in the vertical direction Hr, extending in one plane. In particular, this is the bending area 20 also extending in one plane and, in plan view, has mainly or essentially the shape of an 'Is' (not shown), an 'S' (not shown) or an 'Us' ( 5 . 7 . 9 and 12 ).

In time after the original molding process (step I ) the angle terminal blank 2 in a coating process (step II ), also called the plating process (step II ), are coated (not shown), the coating process (step II ) is optional. In time after the original molding process (step I ) or after the coating process (step II ) becomes the angle terminal blank 2 in a bending process (step III ) to an angle terminal assembly 2 mechanically bent, with a bending angle α between the connection section 10 and the contact section 30 is set in a controlled manner. This will make an angle terminal assembly 2 receive.

The bending process (step III ) or part of the bending process (step IIIb ) can be during an assembly process, e.g. B. an assembly process of the circuit board 0 , respectively. Here, the connection section 10 of the angle terminal 2 already installed. That is, instead of an angle terminal assembly 2 to assemble, is first an angle terminal blank 2 preferably with its connecting section 10 , e.g. B. on / on the circuit board 0 , assembled (soldered, solderless mounted). After that, the bending area 20 finally bent. When installing the connection section 10 can the angle terminal blank 2 already pre-bent, i.e. part of the bending process (step IIIa , see below) may already have been carried out.

In the bending process (step III ) the bending angle α is realized, for which a section of the bending area 20 , which preferably outside the connection section 10 and / or the contact section 30 in the angle terminal blank 2 or in the angle terminal 2 is set up, from its original location on / in the angle terminal blank 2 or in the angle terminal 2 bent out (step IIIa , Rotation around axis parallel to longitudinal direction Lr ), especially folded out (step IIIa ). Here, the connection section 10 (see. 8th ) or the contact section 30 (not shown) bent out (step IIIa ), especially folded out (step IIIa ), become; in such a case, part of the bending angle α is already realized (twisting bending angle).

In this pre-bent area 20 owns the angle terminal 2 (in an intermediate stage between angled terminal blank 2 and angle terminal assembly 2 , which is still at the stage of the angle terminal blank 2 is counted) z. B. in an aligned longitudinal direction Lr of the angle terminal 2 (Projection plane perpendicular to the longitudinal direction Lr ) a mainly or substantially I-shaped, V-shaped (not shown) or U-shaped (not shown) profile (over at least one bending zone 210 . 230 away, see below).

The bending area can then follow 20 can be set according to the swivel bending angle (step IIIb ). Here, the entire bending angle α is realized or The above part of the bending angle is supplemented to the bending angle α. It is in a temporal connection, depending on the training of the bending area 20 possible that the connection section 10 opposite the contact section 30 or vice versa (further) is rotated (not shown). - It is the angle terminal assembly 2 receive.

In one variant (cf. the 5 . 7 . 9 and 12 ) the invention of the bending area 20 in the angle terminal blank 2 as a u-shaped bending area 20 with (exactly) two legs 210 . 230 and (exactly) a connecting bridge 200 educated. The thigh 210 . 230 and the connecting bridge 200 , (220) constitute bending zones ( 210 ,) 220 . 230 in the bending area 20 which are actively bent and / or passively from another bending zone 210 . 220 . 230 can be moved (placed at an angle, adjusted, etc.). The corner areas of the bending zones 210 . 220 . 230 can e.g. B. rounded (not shown) and / or angular.

In the present case, the bending area 20 a connection bending zone 210 (first leg 210 ), a bypass section 200 with bypass bending zone 220 (Connecting web 200 , ( 220 )) and a contact bending zone 230 (second leg 230 ) on. The connection bending zone 210 is with the connection section 10 and the contact bending zone 230 is with the contact section 30 of the angle terminal blank 2 preferably integrally connected. The opposite ends of the bending zones in this regard 210 . 230 in the transverse direction qr are preferred with the bypass section 200 of the angle terminal blank 2 each also preferably integrally connected. The bypass section 200 has the bypass bending zone in its longitudinal center section 220 on.

The bending area 20 is designed in this way or the bypass section 200 is so in / on the angle terminal blank 2 set up the bypass section 200 later on the outside, at the angle terminal assembly 2 trending (cf. 10 ) or inside, in the angle terminal assembly 2 trending (cf. 6 and 8th ) is set up. For this are the connection section 10 and the contact section 30 with the bending area set up for it 20 connected accordingly. See e.g. B. the 5 and 7 (internal bypass section 200 , comparatively short distance (slot 21 )) with the 9 (External bypass section 200 , comparatively large distance (slot 21 )).

That is, at the respective free (outer) longitudinal ends ( Lr ) of the connection section 10 and the contact section 30 opposite (free, inner) longitudinal ends ( Lr ) of the connection section 10 and the contact section 30 , is a slit 21 in the angle terminal blank 2 set up. About this slit 21 are the connection section 10 and the contact section 30 in the angle terminal 2 preferably set up directly adjacent to each other. When transferring (bending) the angle terminal blank 2 into the angle terminal assembly 2 becomes the slit 21 (radially) expanded (cf. 5 after 6, 7 after 8, and 9 after 10). This preferably concerns all embodiments of the invention.

The 5 and 6 show an angle terminal blank 2 for an internal bypass section 200 as well as an angle terminal assembly 2 with an internal bypass section 200 , In the angle terminal blank 2 fall a longitudinal center line ( Lr ) of the connection section 10 and a longitudinal center line ( Lr ) of the contact section 30 essentially together, with the angle terminal blank 2 in a central area between the connection section 10 and the contact section 30 the u-shaped bending area 20 has, at the free ends of the leg 210 . 230 , on the one hand the connection section 10 and on the other hand the contact section 30 are connected at right angles and integrally. There is a gap between them 21 set up.

For transferring the angle terminal blank 2 into the angle terminal assembly 2 is the bypass section 200 from the level of the connection section 10 and the contact section 30 bent out (bending about an axis parallel to the longitudinal direction Lr ), the bending zones 210 and 230 be bent. In a time connection thereafter, the connection section 10 and the contact section 30 mutually around an axis parallel to the vertical axis Mr bent. That is, the bending zone 220 is bent, whereby the bending angle α between the connection section 10 and the contact section 30 sets up. The connection section 10 and the contact section 30 keep their original orientation in the circumferential direction Um in relation to the longitudinal extent Lr of the angle terminal 2 at.

At the angle terminal 2 the 5 and 6 are both thighs 210 . 230 of the U-shaped bending area 20 210 . 230 essentially the same length (longitudinal direction Lr or transverse direction qr ) educated. This is in an embodiment according to the 7 and 8th not the case. Here is the thigh ( 210 ) at which the connection section 10 is provided to be shorter, the bending zone 210 is not realized. Otherwise, this embodiment is essentially the same as the embodiment according to FIG 5 and 6 educated.

For transferring the angle terminal blank 2 into the angle terminal assembly 2 is again the bypass section 200 from the level of the connection section 10 or an original level of the contact section 30 bent out, only that bending zone 230 is bent, which with the contact portion 30 connected is. This will make the connector section 10 about an axis parallel to the longitudinal direction Lr twisted (cf. 7 after 8). One as a pin 10 trained connection section 10 possesses in relation to the longitudinal extent Lr of the angle terminal 2 no longer the same circumferential position (circumferential direction Um) as before the bending zone 230 , Subsequently, the bending angle α is set up analogously to the above.

The 9 and 10 show an angle terminal blank 2 for an external bypass section 200 as well as an angle terminal assembly 2 with an external bypass section 200 , Apart from a larger bending area 20 , which is also mirrored in relation to the 5 in the angle terminal 2 is set up, this embodiment is essentially like the embodiment according to FIG 5 and 6 formed, this embodiment analogous to the embodiment according to 5 and 6 is bent.

Here is the bypass section 200 set up by an amount longer, which corresponds to a thickness of the contact section 30 in the transverse direction qr corresponds, since with an external bypass section 200 this thickness has to be bridged once, something with an internal bypass section 200 (see. 6 ) does not apply. Depending on the design of this embodiment, this can also be the connection section 10 hold true. Setting up the bending angle α between the connection section 10 and the contact section 30 takes place analogously to the embodiment of the 5 and 6 ,

The 12 and 13 show the application of the invention to an angle tab terminal 2 with two connection sections according to the invention 10 . 10 at a single one as a tab contact 30 trained contact section 30 , The two connection sections 10 . 10 with their bending areas 20 . 20 are according to 7 trained, ie the connection sections 10 . 10 are also twisted during bending. Here are the slots 21 . 21 of the two bending areas 20 . 20 facing each other, whereas the bypass sections 200 facing each other with respect to the longitudinal direction Lr in the angle terminal 2 are set up. Another embodiment of at least one connection section 10 or both connection sections 10 . 10 is of course applicable. one 10 of the two connection sections 10 . 10 is spatially before and after its corresponding bending area 20 extended. - The 11 shows an angled tab terminal in this regard 2 according to the state of the art.
