In a conventional punching production of printed circuit board angle terminals falls due to the design of the angle terminals (see. 1 ) a large proportion of punching waste. This results in high tooling costs and a low OTE (Overall Tool Effectiveness). Furthermore, in this case, a coating speed is comparatively low, and a consumption of coating materials (in particular high-quality materials, such as, for example, gold or silver) is comparatively high due to the angled shape. When winding such angle terminals winding damage can occur comparatively quickly and / or transport damage comparatively heaped. Furthermore, there is a recurring occurrence of dimensional deviations and / or production deviations (geometry errors) during manufacture.

A preferred starting point is a substantially square or substantially rectangular main cross-section of a printed circuit board angular terminal, which is considered below. B. as Biegewinkelterminal or angled printed circuit board contact device is beschzeichenbar. Furthermore, in the following, such an angular terminal does not mean a terminal whose printed circuit board connection section and its counter terminal contact section are only offset and / or parallel 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 angular terminal placement has taken place between the connection section and the contact section. It is possible to bend the angular terminal Bestückling only after its mounting on a circuit board.

The electrical printed circuit board angle terminal according to the invention has exactly one or at least one (eg exactly two or exactly three) printed circuit board connection sections for the electromechanical connection of the angular terminal to a printed circuit board (eg with a conductor track, a metal tongue, a pad, etc.). ), and a Gegenterminal-contact portion for the electromechanical connection of the Winkelterminals with a Gegenterminal (eg on a plug / cable, a second circuit board, etc.), wherein at least partially established between the terminal portion and the contact portion, a mechanically bendable bending area in the angular terminal is, wherein for the bending region preferably a cross section of the angle terminal changes in a longitudinal direction of the angle terminal.

This concerns, s. a. in the following, both a blank, z.

H. the angle terminal is generally suitable for a possibly z. B. electrically non-conductive substrate such as a plastic housing (defined as a printed circuit board).

By means of the bending region, an angle between the connection section and the contact section can be set or adjusted 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 region. Under 'controlled' should be z. B. dominated, not unintentionally or validly verifiable be understood. The bending area may be formed as a necessarily bendable (angled terminal blank) or a necessarily bent (angular terminal fitting) bending area, which bendable or bent by a bending process, wherein the bending angle is not finally established or established by a primary molding process.

In embodiments, the bending region can be formed or formed as a Verschwenkbiegebereich, whereby a material layer of the contact portion relative to a material layer of the connection portion in a plane (projection plane, straight projection) is pivoted or pivoted. Here the plane is not mitverschwenkt. Instead, the contact section or its material layer lies opposite the connection section or its material layer in a plane in which also the contact section or the connection section lies (at least regionally) or in a projection plane, in which preferably also the contact section or the Connecting portion (at least partially), pivots. In embodiments, the bending region may be formed or formed as a Verdrehbiegebereich, whereby a cross section of the contact portion with respect to a cross section of the connecting portion is rotatable (twistable) or twisted (twisted).

In this case, it is preferable to form the bending region as a pure swiveling bending region (eg, first and third embodiment, see below) or a composite twisting-and-pivoting bending region (eg, second embodiment, see below). - A Verschwenkbiegewinkel (angle in a plane) indicates by what angle z. B. is a center line of a material layer of the angle terminal in the bending section is pivoted or pivoted. The Verdrehbiegewinkel indicates the angle z. B. a cross section of the angle terminal in the bent portion is rotatable or twisted. A combination of Verschwenkbiegewinkel and Verdrehbiegewinkel is of course applicable, resulting in a three-dimensional bending angle or a solid angle.

The terminal portion and the contact portion may extend in an angular terminal blank of the angular terminal substantially along a single straight line or along at least two substantially parallel straight lines. Further, in an angle terminal of the angle terminal, the bending angle between the terminal portion and the contact portion in a projection plane (even projection) may have a value different from 180 °. In the angle terminal blank, the terminal portion and the contact portion extend substantially in a plane (sheet plane during punching).

Of course, other angles may be applicable. A straight overall length of an angular terminal blank may be longer than an angular total length of an angular terminal patch relating to that angular terminal blank.

In embodiments, the bending area may include a bypass section of the angle terminal. In this case, the bypass section can extend 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. In addition, the bypass section itself may have a bypass bending zone. Furthermore, the bypass section can be connected to the contact section via a contact bending zone. - This in turn affects both the angular terminal blank and the angular terminal Bestückling. In the angled terminal blank, the bending zone (s) are not bent in a controlled manner, whereas the bending zone (s) in the angular terminal assembly are bent in a controlled manner. A respective inner or outer corner region of the bypass section, the connection bending zone and / or the contact bending zone can be angular (preferred) or rounded.

In this case, a first limb of the U-shaped bending region may have one / the connection bending zone, the connecting web of the U-shaped bending region, one / the bypass bending zone and / or a second leg of the U-shaped bending region a contact bending zone. For this purpose, of course, an i-shaped, s-shaped or v-shaped bending area can of course also be set up in the angular terminal blank.

In an angle terminal blank, a boundary of the bending region 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 may 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 terminal bending zone can open at an approximately 90 ° angle in the connection section and / or at an approximately 90 ° angle in the bypass section, wherein other angles are of course applicable here. In addition, the contact bending zone can open at an approximately 90 ° angle in the contact section and / or at an approximately 90 ° angle in the bypass section. Other angles in one Plane of the angle terminal blank, z. B. about 30 °, about 45 °, about 60 °, of course, if applicable, applicable.

In an angular terminal placement, the angular terminal may have a substantially three-dimensional shape. Furthermore, the bending region may be formed as a meandering bend having one, two, three or four bending zones. Furthermore, the bending region may be formed as a bending region extending outside or in between the connection section and the contact section. In addition, the terminal portion and the contact portion may be pivoted against each other at an angle and / or rotated. Applicable angles are here, independently of each other, again in each case: about 30 °, about 45 °, about 60 °, about 75 °, about 90 °, in turn, the approximately 90 ° angle is preferred. Of course, other angles are applicable again. Furthermore, a longitudinal end portion of the terminal portion may be arranged to be directly adjacent to a longitudinal end portion of the contact portion via a gap.

In addition, the bypass section can be folded out of a plane of the connection section and / or of the contact section. Here is preferably an approximately 90 ° angle application, in turn, if necessary, another angle is applicable. The connection bending zone can connect the connection section to the bypass section over an approximately 90 ° angle or an approximately 180 ° angle. Furthermore, the contact bending zone can connect the contact section over an approximately 90 ° angle or an approximately 180 ° angle with the bypass section. Other angles (about 30 ° to about 180 °) can be set up again, if necessary. A bending axis for the terminal bending zone lies substantially parallel to a center line of the connection section, and / or a bending axis for the contact bending zone lies substantially parallel to a center line of the contact section.

According to the invention, a shaping of the angle terminal can not take place exclusively by a stamping process. This can be z. B. also fall a punching process. The angle terminal can z. Example, as an angle terminal for soldering (eg., For a contact system in the area Soldering), a solderless angle terminal (eg., For a contact system in the Pressfit area) or an SMD angle terminal be formed (SMD: Surface-Mounted Device, surface-mounted component). Here, the connection section z. B. as a Lötpin, a, Multispring ', an' Actionpin ', as, Eye-of-the-Needle' etc. may be formed. Further, in this case, the contact portion as a nano-Pinterminal, as an MQS Pinterminal (MQS: Micro Quadlock System), a tab terminal, etc. may be formed. Another contact portion and / or another connection portion is of course applicable. In embodiments, the bending area may be formed as a spring area of the angle terminal. Furthermore, the angle terminal may comprise two or more connection sections each having a bending region. In such a case, the angle terminal is preferably formed as an angle terminal. Furthermore, the angle terminal can be produced by a manufacturing method according to the invention.

In the method according to the invention for producing an electrical circuit board angular terminal, in an original molding process, preferably a stamping process, the angular terminal is formed as an angular terminal blank, wherein the angular terminal blank is coated after the primary molding process in an optional coating process, and after the original molding process or temporally after the coating process, the angle terminal blank is formed in a bending process to an angular terminal Bestückling.

In the prototyping process, a circuit board connection portion and a counter-terminal contact portion of the angle terminal may be formed substantially along parallel straight lines extending in the angle terminal. Such a line is z. B. defined by a longitudinal center line or an outer boundary line of the terminal portion or the contact portion. Here, the parallel lines can coincide. Furthermore, in the prototyping process between the terminal portion and the contact portion, a bending portion may be formed with a bypass portion of the angle terminal. By the bending portion or the bypass portion, an angle is set as a bending angle between the connection portion and the contact portion controlled. In addition, in the primary forming process, an extension of one / of the bypass section of the angle terminal can be offset, in particular offset in parallel, to form an extension of the connection section and / or of the contact section.

In the bending process, first the bypass section can be bent out of a plane of the connection section and / or the contact section. Here, the terminal portion may be bent out of the plane of the contact portion or the contact portion out of the plane of the terminal portion. Furthermore, in the bending process, after the bending out of the bypass section, 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 terminal portion and the contact portion is controlled as a bending angle.

Furthermore, in the bending process, after the bending-out of the bypass section, the connection section opposite the Contact section or vice versa be twisted. Here, a rotation angle in a projection plane (straight projection) between the connection portion and the contact portion is controlled as a bending angle. In addition, the bending process can be carried out in time prior to an assembling process / assembly process of a printed circuit board or integrated into the assembly process / assembly process of the printed circuit board.

The primary molding process can be designed as a pure stamping process or a pure stamping process. Ie. the pure punching process is not designed as a punching method and / or further comprises no other manufacturing method, such. B. an actual, taught here, bending process; This is also applicable to the stamping process. Furthermore, the coating process may be configured as a global coating process or a selective coating process (preferred). In addition, the bending process can be integrated in the primary molding process, or the bending process is performed separately from the primary molding process. Furthermore, the angle terminal can be designed as an inventive printed circuit board angular terminal.

A printed circuit board according to the invention has at least one electrical circuit board angular terminal, wherein the angular terminal is formed according to the invention and / or produced according to the invention. Here, the angle terminal can only be attached to / on the circuit board, the angle terminal does not require a housing for the electromechanical function. Of course, it can also be applied to a housing. - A connector according to the invention comprises at least one electrical circuit board angular terminal, wherein the angle terminal according to the invention formed and / or produced according to the invention, and / or the connector has a circuit board according to the invention. The circuit board or connector may have an angular terminal arrangement with a plurality of angle terminals. In this case, the angle terminals of an angle terminal arrangement can all be bent individually and / or formed substantially equally angled. Furthermore, the angle terminal, the angle terminal arrangement, the circuit board or the connector may have a housing which supports the function of the angle terminal or the angular terminal arrangement.

According to the invention can be variable angle terminals with z. B. Mäandbiegungen for the realization of variably adjustable bending angles without the aid of elaborate punching, elaborate coating process and / or complex bending process produce. Depending on a configuration of an angle terminal or angular terminal arrangement having a plurality or plurality of angle terminals, there are a number of major advantages. A stamping process can work much more effectively because it can produce a larger number of pieces per unit of time compared to the prior art. The punches may be reusable for other configurations of angle terminals or angle terminal arrangements. The cost (OTE) can be greatly reduced by selective coating possible by the invention.

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

According to the invention, angle terminal terminals having two terminal portions or a multi-pitch zone (two or more than two terminal portions) are applicable for inserting a 90 ° variant into a printed circuit board. Such a geometry can also be used in an angle terminal. Substitution of an eye-of-the-needle connection section by a cost-effective action pixel as a connection section is possible. Nevertheless, Eye-of-the-Needle connector sections may 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 in case of vibration stress. Of course, according to the invention, angle terminals of any contact system, in particular a contact system in the press fit and / or soldering area, can be realized.

The punching process results in improved stroke rates. The coating process results in faster driving in electroplating. The coating process is simplified significantly, since it is only a 'normal geometry', and thus can be driven with a higher coating speed. Due to the geometry according to the invention, a bending of the connection sections in the assemblage can take place (individual connection section or multi-stop zone).

Ie. an alignment of the terminal sections or the angle terminals to the circuit board is possible in the assemblage by the bending process (setting of wobble circles). The connection sections or the contact sections can be bent at different angles. In applications, an inlay process may no longer be necessary, ie there is no need to build costly inlay handling systems.
