Description

Printed circuit board for receiving at least one contact pin, method for contacting a printed circuit board and circuit

[0001] The invention relates to a printed circuit board for receiving at least one contact pin according to the preamble of claim 1. Furthermore, the invention relates to a method for contacting a printed circuit board according to claim 13 and to a circuit with a printed circuit board according to claim 15.

[0002] Known circuit boards which are to be contacted by means of a contact pin, for example by means of a press contact or several press contacts or also by means of a twist contact or several twist contacts, must have a certain thickness and / or a certain mechanical strength, particularly in the surface direction, to accommodate the respective contact pin in order to avoid permanent damage when the contact pin is inserted. Even if no permanent damage occurs, it can happen that in the case of circuit boards which are too thin and / or have low mechanical strength and / or rigidity that a corresponding contact pin is not sufficiently securely fastened in the circuit board and / or that insufficient contact is made. Such thin circuit boards, for example, have a thickness of preferably a maximum of up to 0.8 millimeters, in particular a maximum of up to 0.5 millimeters.

[0003] To reinforce thin circuit boards to accommodate at least one contact pin, sleeve-like reinforcements have to be inserted, which are complex to install and comparatively expensive. These sleeve-like reinforcements can be press-fit sleeves or, alternatively, so-called vias.

[0004] The object of the invention is to improve the state of the art.

[0005] The object is achieved by a printed circuit board for receiving at least one contact pin, wherein the printed circuit board has a printed circuit board body with a printed circuit board thickness, wherein the printed circuit board thickness is determined along a thickness direction and between a receiving side and a counter side opposite the receiving side and the contact pin receptacle is aligned along the thickness direction and the contact pin receptacle is designed to receive the contact pin along the thickness direction and fix the contact pin by means of contact forces acting radially to the thickness direction, wherein the contact pin receptacle has a first receiving body that is electrically contacted with the printed circuit board or is arranged in the first receiving body or is encompassed by the first receiving body,wherein the first receiving body is arranged outside the circuit board thickness on the receiving side and has a receiving opening aligned along the thickness direction for receiving the contact pin.,

[0006] By arranging the first receiving body outside the thickness of the circuit board on the receiving side, a particularly mechanically stable receptacle is created, independent of the circuit board body. This allows the first receiving body to be mechanically adapted to receiving the contact pin. In particular, this enables the insertion of contact pins for contacting particularly thin circuit boards.

[0007] The core idea of ​​the invention is to arrange the first receiving body outside the circuit board thickness and / or the circuit board body, preferably on the circuit board or under the circuit board, in particular on the receiving side, and thus to create a receptacle specifically tailored to a contact pin, into which the contact pin can be inserted. Optionally, the first receiving body is electrically connected to the circuit board, for example with a Conductor track, contacted. Alternatively, contact is formed by the contact pin if the contact pin is arranged in the receptacle.

[0008] The following terms are explained in this context:

[0009] A "printed circuit board" describes a so-called printed circuit, particularly one that is etched, vapor-deposited, or manufactured in another way, also known as a "circuit board" or "circuit board," i.e., an electromechanical body with, for example, conductive paths for conducting electrical current or electrical signals. Such a printed circuit board typically carries electrical and / or electronic components, with the actual printed circuit board having a "printed circuit board body" that fulfills the basic mechanical function of the printed circuit board. Such a printed circuit board body is manufactured, for example, as a composite material, for example, from glass fibers and synthetic resin or foil.

[0010] A "thickness direction" is defined by a surface normal to the PCB body and / or by an orthogonal to a planar orientation of the PCB body. This thickness direction serves as a geometric reference for an extension of the PCB body along this thickness direction, which then determines a "PCB thickness" as the maximum extension. In this context, it should be noted that the orthogonality does not have to be mathematically exact, but a technically induced deviation of, for example, up to 10° is included.

[0011] The thickness of the circuit board is determined between a "receiving side", i.e. a side on which the contact pin is fed or arranged, and a "counter-side" opposite the receiving side.

[0012] A "contact pin," which can be present in various embodiments as a "press contact" or also as a "twist contact," refers in this context to an electrical or electronic contacting element. The contact pin has, for example, a round, in particular oval or circular cross-section. Alternatively, or in some sections, the contact pin can have a quadrangular cross-section, preferably a rectangular or square cross-section. In particular, the contact pin has a cylindrical, square, and / or flat outer contour or shape. The outer contour or shape defines, in particular, a longitudinal extent and / or surface direction of the contact pin. Optionally, the contact pin can be conical along the longitudinal extent and / or surface direction. Optionally, the contact pin can additionally have resilient elements.

[0013] A "press contact" is inserted into the circuit board body or into a corresponding "contact pin receptacle," according to the invention, in the first receptacle, similar to an electrical plug, but usually on a smaller scale, and is then held within the press contact receptacle by a contact force, in particular a pressure, specifically substantially orthogonal to the thickness direction. By means of such a contact pin, for example, electronic components are fixed to the circuit board or electrical connections, for example for connecting cables, are realized.

[0014] Alternatively or additionally, instead of a press contact, a so-called "twisting contact" can also be used analogously. Such a twisting contact is engaged with the respective receiving body by means of a bayonet-like or toggle-like connection, in particular by means of radial contact forces. For this purpose, the contact pin is first axially inserted along the thickness direction in The crimping tool is inserted into the respective receptacle and then secured by a rotating motion. Alternatively or additionally, the contact pin can also have or form a crimp receptacle for accommodating a wire, shield, braid, or conductor. For example, the crimp receptacle on a press-in contact can be crimped directly during the press-in process, allowing two work steps to be performed in one operation.

[0015] For this purpose, the "contact pin receptacle" is designed, for example, as a bore or an opening or even as a position on the circuit board provided for a contact pin. For example, the contact pin receptacle has a cross-section that corresponds to and / or is suitable for the contact pin. Preferably, the contact pin receptacle has a round, in particular oval or circular, cross-section, or a quadrangular, in particular rectangular or square, cross-section. In particular, the contact pin receptacle is conical along its longitudinal extent and / or surface direction. The contact pin is inserted, for example, with the resilient elements in the radial direction into a component of the circuit board, in particular into the receptacle body, in particular into the contact pin receptacle, and can be fixed by contact forces.In the case of the flat contact pin, fixing often takes place along the longitudinal extension and / or the surface direction of the contact pin within the receiving body of the contact pin receptacle.

[0016] A "receiving body" in this context is a geometric body arranged separately from the circuit board body, which has or forms the contact pin receptacle and which is designed and constructed for electrically contacting the contact pin with the circuit board, for example with conductor tracks of the circuit board. The arrangement of the receiving body "outside" the thickness of the circuit board, specifically outside the volume of the circuit board body, represents This ensures that the receiving body can also be subsequently arranged and specifically adapted to the contact pin(s). According to the invention, the contact pin receptacle encompasses or forms the receiving body. Alternatively or additionally, the receiving body encompasses the contact pin receptacle.

[0017] In order to mechanically reinforce the circuit board, the first receiving body extends over a receiving area of ​​the circuit board along the receiving side of the circuit board body, with the first receiving body being mechanically connected to the receiving side, particularly over a large area or at one or more points. Thus, mechanical forces of the contact pin can be absorbed by the first receiving body through the mechanical connection to the circuit board.

[0018] A "receiving area" refers to the area of ​​influence on the circuit board formed by the contact pin and the first receiving body, i.e. an area in which mechanical forces must be effectively introduced into the circuit board.

[0019] In one embodiment, the first receiving body has an inner extension body extending along the thickness direction, wherein the inner extension body extends from the receiving side into the circuit board body and in particular has or continues the receiving opening.

[0020] With this "extension body", i.e. an extension of the receiving body into the circuit board body, which is particularly present in the case of an "internal extension body", a sleeve-like extension of the receiving body into the circuit board can be created, which, for example, has a longer length along the thickness direction. Friction surface or pressing surface is created between the contact pin and the receiving body.

[0021] In particular, the inner extension body is designed such that the inner extension body has a cross section in a thickness direction which is equal to or smaller than a feedthrough opening in the circuit board body, so that the inner extension body is accommodated in the feedthrough opening in the circuit board body, in particular radially to the thickness direction. The inner The expansion body can be accommodated in the feedthrough opening without force or "with force" or with force applied.

[0022] Such a "feedthrough opening" is, for example, a hole in the circuit board body. The feedthrough opening can be designed, for example, as an elongated hole. Preferably, the feedthrough opening has a cross-section that corresponds to and / or fits the contact pin. Preferably, the feedthrough opening has a round, in particular oval or circular, cross-section, or a quadrangular, in particular rectangular or square, cross-section. In particular, the contact pin receptacle is conical along its longitudinal extent and / or surface direction.

[0023] In a further embodiment, the first receiving body has an outer extension body extending along the thickness direction, wherein the outer extension body extends from the receiving side away from the circuit board body and in particular has or continues the receiving opening. Analogous to the previous embodiment, in which the inner extension body extends into the circuit board body, with this embodiment of an outer extension body, for example, a sleeve-like projection can be formed on the circuit board by means of the outer extension body, which allows For example, to accommodate a contact pin passing through from an opposite side of the circuit board with a long receiving surface radially along the thickness direction, or, for example, to be able to arrange a component with the outer extension body spaced apart from the circuit board. Both embodiments can also be combined with an arrangement of the inner extension body inside and the outer extension body outside the circuit board body, provided this is expedient, for example, for the geometric arrangement of an electronic component or to ensure secure contact.

[0024] In one embodiment, the inner extension body and / or the outer extension body is / are narrowed or closed on a terminal side facing away from the received contact pin. Thus, microscopic chips or microscopic abrasion that accrue, for example, when inserting and / or receiving a contact pin can remain in the respective extension body, preventing contamination of the circuit board.

[0025] For this purpose, the inner extension body and / or the outer extension body can be at least partially filled with a filler, in particular with an adhesive, to increase mechanical strength. This filler can be used to specifically increase mechanical strength and also easily bind chips or abrasion debris.

[0026] In order to be able to make a through-hole connection from one side of the circuit board to the other side of the circuit board using the contact pin, for example, when at the same time a component is connected to the circuit board using the contact pin, a second receiving body is arranged on the opposite side, whereby the first Electrical contact is established between the receiving body, the second receiving body, and a contact pin received and fixed in the first receiving body and the second receiving body. This eliminates the need for additional elements for through-plating different sides of the circuit board.

[0027] In a further embodiment, the first receiving body and / or the second receiving body is or are mechanically and / or electrically connected to the circuit board body, in particular to conductor tracks arranged on the circuit board body, by means of welding, screwing, pressing, riveting, gluing and / or by means of soldering or another suitable method.

[0028] In order to be able to produce the first receiving body, the inner extension body, the outer extension body and / or the second receiving body efficiently and inexpensively and to be able to provide them, for example, as a separate component for a printed circuit board, the first receiving body, the respective extension body and / or the second receiving body is or are produced by means of punching, by means of bending, by means of deep drawing, by means of an additive process, by means of a metal (die) casting process, by means of metallization of plastic components and / or by means of machining processes.

[0029] In a further aspect, the object is achieved by a method for contacting a printed circuit board according to claim 13. In this case, the printed circuit board is provided, the contact pin is positioned along the thickness direction at the receiving opening so that the contact pin is positioned opposite the receiving opening ready for contact, and the contact pin is then inserted into the receiving opening, wherein the insertion takes place along the thickness direction and thus the contact pin is received in the receiving opening and, in particular, fixed in the receiving opening by pressing and / or screwing Thus, the circuit board can be contacted according to the invention using a contact pin.

[0030] In one embodiment, the crimp receptacle is crimped during the insertion of the contact pin. In particular, the crimp receptacle is moved relative to the circuit board and crimped to the circuit board by means of the contact.

[0031] In a further aspect, the object is achieved by a circuit having a printed circuit board according to one of the previously described embodiments and at least one contact pin, wherein the printed circuit board is contacted by means of one contact pin or by means of several contact pins according to the previously mentioned method to form the circuit.

[0032] Such a circuit can be manufactured efficiently and inexpensively, whereby circuits can be contacted in particular with particularly thin and / or mechanically less resilient circuit boards.

[0033] A "circuit", also referred to as a "module", is an assembly comprising a printed circuit board, one or more contact pins and, for example, electronic components, whereby such a circuit is in particular a fully or partially functional electronic unit which is provided, for example, for a specific switching or control task.

[0034] The invention will be explained in more detail below using exemplary embodiments. Figure la is a schematic representation of a printed circuit board with a press contact in a sectional side view, Figure 1b is a schematic representation of another circuit board with a press contact in a sectional side view, Figure 2 is a schematic representation of a printed circuit board with a crimp clamp in a sectional side view, as well as Figure 3 is a schematic representation of a modified circuit board with a crimp clamp in a sectioned side view.

[0035] A printed circuit board 101 is shown as an example as part of a circuit for, for example, an electronic switching assembly. The printed circuit board 101 has a base body 103 made of a fiberglass composite material, on which a respective conductor track 105 and 107 is applied on a top side 171, which forms a receiving side, and a bottom side 173, which forms a counter side, in order to conduct electrical current and electrical signals, respectively. The conductor tracks are made of copper or other conductive metals and / or metal alloys.

[0036] An opening 109 is provided in the base body along a longitudinal axis 181, which serves to insert a press contact 141. The longitudinal axis is arranged along a thickness direction 197 of the circuit board 101, the circuit board having a thickness of 195.

[0037] Respective vias 111 run from a respective connection 113 between the conductor track 105 and the conductor track 107 and thus contact both conductor tracks on both different sides of the circuit board 101 with each other.

[0038] On the upper side 171, a receptacle 131 is electrically and mechanically fastened to the conductor track 105 by means of a contact point 121, which serves as a receptacle body. The receptacle 131 is formed as a mechanically load-bearing component made of an electrically conductive metal and receives the press contact 141 on a pressing surface 151 arranged in the extension of the opening 109. The press contact 141 has a head 143, wherein the head 143 is deformable radially to the longitudinal axis 181. By inserting the press contact 141 along the longitudinal axis 131 via a press path 185 along the thickness direction 197, the press contact is frictionally fastened and fixed along the pressing surface 151 in the receptacle 131. Thus, an electrical contact of the press contact 141 via the receptacle 131 with the conductor track 105 is made via an insertion depth 191,

[0039] Analogously (cf. Figure 1bJ), a press contact 161 is received in an opening 110 of the printed circuit board 101. For this purpose, the press contact is received in a receptacle 133 on the underside 173 of the printed circuit board 101. For this purpose, the receptacle 133 is arranged by means of a contact point 123 on the conductor track 107 on the underside 173 of the printed circuit board 101 and is electrically contacted as well as mechanically fixed and fastened. The press contact 161 is designed analogously to the press contact 141, has a head 163 and is longer than the press contact 141 in order to reach the receptacle 133 arranged on the underside 173. The press contact 161 is thus fastened in the receptacle 133 along a press-in path 187 at an insertion depth 193.

[0040] It should be mentioned in this regard that, for example, if the receptacle 131 and the receptacle 133 are arranged on opposite sides of the opening 209 or 210, contacting of the conductor track 105 with the conductor track 107 with a single, longer press contact is possible, analogous to the press contact 141, and thus through-plating elements can be saved.

[0041] A printed circuit board 201 (see Figure 2) has, analogously to the previous example, a base body 203, a conductor track 205 on a top side 271, and a conductor track 207 on a bottom side 273. The printed circuit board 201 has a thickness 295 along a thickness direction 297. Analogously to the previous example, vias 211 with terminals 213 and fillings 215 are provided. By means of a contact point 221 is a receptacle 231, which also serves as a receptacle body, on the underside 273, which is electrically and mechanically contacted and secured to the conductor track 207. The circuit board 201 also has openings 209 and 210. Along the longitudinal axes 281 and 282 defined by the openings 209 and 210, a receptacle base body 232 and receptacle sleeves 233, which serve as extension bodies of the receptacle 231, are arranged on the underside 273. The receptacle base body 232 is arranged parallel to the conductor track 207 on the underside 273, and the receptacle sleeves 233 extend along the longitudinal axes 281 and 282 away from the circuit board 201, i.e., along the thickness direction 297. In particular, the receptacle sleeves 233 are external extension bodies.

[0042] A crimp clamp 241 extends through the openings 209 and 210. The crimp clamp 241 has an upper part 243, which is arranged parallel to the surface of the conductor track 201. Legs 247, which run parallel to the longitudinal axes 281 and 282, then adjoin orthogonally to the upper part 243 along bends 245. The legs 247 extend through the openings 209 and 210. A crimp 249, which is arranged between the upper part 243 and the conductor track 205 on the inside of the crimp clamp 241, receives a stranded wire 251 in a form-fitting manner and makes electrical contact. The legs 247 are then inserted into the receiving sleeves 233 and are frictionally received on the pressing surface 261 (into the image plane in Figure 2) within the receiving sleeves 233, analogous to the previous example of the press contacts 241 and 261.Thus, the crimp clamp 241 is fixed along a press-in path 285 in the insertion depth 291 in the receptacle 231 and simultaneously contacts the stranded wire 251 with the conductor track 205 and the conductor track 207.

[0043] Here, when inserting the crimp clamp 241 along the press-in path 285, a crimping of the crimp 249 is implemented or achieved by guiding the crimp 249 against the printed circuit board 201 and is pressed together by contact with the circuit board 201.

[0044] A modified circuit board 201 (see Figure 3) differs from the circuit board 201 shown in Figure 2 in the orientation and position of the receiving sleeves 233, which form internal extension bodies. As internal extension bodies, the receiving sleeves 233 extend into the openings 209, 210 in the base body 203 of the circuit board 201. The receiving sleeves 233 have a cross-section that is essentially the same as that of the openings 209, 210. As a result, the receiving sleeves 233 bear against the boundary walls of the openings 209, 210 with force applied. In an alternative embodiment, the sleeves can also be received in the openings 209, 210 without force.
