Description

Field of the Invention

[0001] The present invention relates to a printed circuit board for receiving at least one contact pin according to the preamble of claim 1. The present invention also relates to a method for connecting a printed circuit board according to claim 13 and a circuit having a printed circuit board according to claim 15. Background Art

[0002] In order to receive corresponding contact pins, especially in the surface direction, known printed circuit boards that are contacted by contact pins, for example by pressing contacts or a plurality of pressing contacts, or also by rotary contacts or a plurality of rotary contacts, must have a certain thickness and / or a certain mechanical strength, especially in the surface direction, so as not to be permanently damaged due to the insertion of the contact pins. Even if no permanent damage occurs, if the printed circuit board is too thin and / or has low mechanical strength and / or stiffness, the corresponding contact pins may not be fastened firmly enough in the printed circuit board and / or insufficient contact may occur. For example, the thickness of such a thin printed circuit board is preferably at most 0.8 mm, especially at most 0.5 mm.

[0003] In order to strengthen a thin printed circuit board for receiving at least one contact pin, sleeve-shaped reinforcements have hitherto had to be introduced, which requires complex installation and results in relatively high costs. The sleeve-shaped reinforcement can be, for example, a press-in sleeve, or alternatively a so-called through-hole. Summary of the Invention

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

[0005] This object is achieved by a printed circuit board for receiving at least one contact pin, wherein the printed circuit board comprises a printed circuit board body having a printed circuit board thickness, wherein the printed circuit board thickness is determined along a thickness direction and between a receiving side and an opposite side opposite the receiving side, and the contact pin receiving portion is oriented along the thickness direction, and the contact pin receiving portion is arranged for receiving a contact pin along the thickness direction and fixing the contact pin by means of a contact force acting radially with respect to the thickness direction, wherein the pressing contact receiving portion has a first receiving body that is electrically connected to the printed circuit board or is arranged in or surrounded by the first receiving body, wherein the first receiving body is arranged outside the printed circuit board thickness at the receiving side and has a receiving opening oriented along the thickness direction for receiving the contact pin.

[0006] By arranging the first receiving body outside the printed circuit board thickness at the receiving side, a particularly mechanically stable receiving portion independent of the printed circuit board body is provided. Thus, the first receiving body can be mechanically adapted to receive the contact pin. In particular, this makes it possible to insert contact pins for contacting particularly thin printed circuit boards.

[0007] In this case, the core idea of the present invention is to arrange the first receiving body outside the thickness of the printed circuit board and / or the printed circuit board body, preferably on or under the printed circuit board, in particular on the receiving side, so as to provide a receiving portion specifically adapted to the contact pin, into which the contact pin can be inserted. Optionally, the first receiving body is electrically connected to the printed circuit board, for example, electrically connected to a conductor track. Optionally, when the contact pin is arranged in the receiving portion, a contact connection site is formed by the contact pin.

[0008] In this context, the following terms should be explained:

[0009] "Printed circuit board" describes the so-called printed circuit, in particular an etched circuit, a vapor deposition circuit or a circuit manufactured in other ways, which is also called "Circuit Board" or "Platine" for example, that is, an electromechanical body having conductor tracks for conducting current or electrical signals. Thus, such a printed circuit board usually carries electrical and / or electronic components, and the actual printed circuit board has a "printed circuit board body" that performs the basic mechanical function of the printed circuit board. In this case, such a printed circuit board body is made of, for example, glass fiber and synthetic resin or film.

[0010] "Thickness direction" is defined by the normal line of the plane of the printed circuit board body and / or the orthogonal line oriented by the plane of the printed circuit board body. This thickness direction serves as a geometric reference for the extension of the printed circuit board body along this thickness direction. Thus, the extension determines the "printed circuit board thickness" as the maximum extension. In this context, it should be noted that the orthogonality here is not necessarily mathematically precise, but includes technical deviations of up to 10° for example.

[0011] In this case, the printed circuit board thickness is determined between the "receiving side" (i.e., the side where the contact pin is provided or arranged) and the "opposite side" opposite to the receiving side.

[0012] The "contact pin", which can exist as a "push contact" or "rotary contact" in different embodiments, refers to an electrical or electronic contact element. The contact pin has, for example, a circular cross-section, in particular an oval or circular cross-section. As an alternative or partial supplement, the contact pin can have a rectangular cross-section, preferably a rectangular or square cross-section. Specifically, the contact pin has a cylindrical, square and / or flat outer contour or shape. The outer contour or shape particularly defines the longitudinal extension and / or the surface direction of the contact pin. Optionally, the contact pin can be formed as a cone along the longitudinal extension and / or the surface direction. Optionally supplemented, the contact pin can include an elastic element.

[0013] In this case, the "pressing contact" is similar to an electrical plug, but is usually inserted into the printed circuit board body or the corresponding "pin receptacle" in a smaller size. According to the present invention, it is inserted into the first receiving body, and then, by the contact force, especially the pressure, it is basically held inside the pressing contact receptacle in a direction orthogonal to the thickness direction in certain cases. With the aid of such a pin, for example, an electronic component is fixed to the printed circuit board, or an electrical connection for connecting a cable is realized.

[0014] Alternatively or additionally, a so-called "rotating contact" can also be used similarly instead of the pressing contact. This rotating contact engages with the corresponding receiving body through a bayonet-shaped or knuckle-shaped connection, especially a connection that acts in a force-coupling manner by means of a radial contact force. For this purpose, the pin is first axially inserted into the corresponding receiving body along the thickness direction and then fixed by a rotational movement. Alternatively or additionally, the pin can also include or form a crimp receptacle for receiving a wire, a shielding layer, a braid, or a conductor. For example, when the crimp receptacle is pressed into the pressing contact, the crimp receptacle can be directly joined to the pressing contact so that two working steps can be carried out in a combined working step.

[0015] For this purpose, the "pin receptacle" is designed, for example, as a hole or a notch, or also as a position provided on the printed circuit board for the pin. For example, the pin receptacle has a cross-section corresponding to and / or suitable for the pin. The pin receptacle preferably has a circular cross-section, especially an oval or circular cross-section, or a quadrilateral cross-section, especially a rectangular or square cross-section. In particular, the pin receptacle is conical along its longitudinal extension and / or surface direction. The pin is inserted, for example, together with an elastic element into a component of the printed circuit board, especially into the receiving body, especially into the pin receptacle, and can be fixed by the contact force. In the case of a flat pin, the fixing usually occurs inside the receiving body of the pin receptacle along the longitudinal extension and / or surface direction of the pin.

[0016] In this context, the "receiving body" is a geometric body arranged separately from the printed circuit board body. The receiving body has or forms a pin receptacle and is arranged and configured to electrically connect the pin to the printed circuit board, that is, to electrically connect to the conductor track of the printed circuit board, for example. In this case, arranging the receiving body "outside" the thickness of the printed circuit board, that is, especially outside the volume of the printed circuit board body, ensures that the receiving body can also be arranged subsequently, for example, and can be implemented to be specifically suitable for the pin. According to the present invention, the pin receptacle includes or forms the receiving body. Alternatively or additionally, the receiving body includes the pin receptacle.

[0017] In order to mechanically reinforce the printed circuit board also particularly by means of the receiving body, the first receiving body extends through the receiving area of the printed circuit board along the receiving side of the printed circuit board body, wherein the first receiving body is mechanically connected to the receiving side, in particular in a face-to-face manner or in a single or multiple point manner. Thus, the mechanical force of the contact pin can be received by the first receiving body through the mechanical connection to the printed circuit board.

[0018] The "receiving area" here refers to the affected area on the printed circuit board formed by the contact pin and the first receiving body, that is, the area in which mechanical force must be effectively introduced into the printed 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 printed circuit board body and particularly has or extends into a receiving opening.

[0020] With this "extension body", that is, the extension of the receiving body into the printed circuit board body, particularly in the case of the "inner extension body", a sleeve-like extension of the receiving body into the printed circuit board can be produced, for example, which produces a longer friction surface or pressing surface along the thickness direction between the contact pin and the receiving body, for example.

[0021] In particular, the inner extension body is configured such that the inner extension body has a cross-section in the thickness direction that is equal to or smaller than the through-guiding opening in the printed circuit board body, such that the inner extension body is received in the through-guiding opening in the printed circuit board body, particularly radially with respect to the thickness direction. In this case, the inner extension body can be received in the through-guiding opening without acting force or "with force" or under the application of force.

[0022] In this case, such a "through-guiding opening" is, for example, a hole in the printed circuit board body. The through-guiding opening can be in the form of, for example, an elongated hole. Preferably, the through-guiding opening has a cross-section corresponding to and / or suitable for the contact pin. The through-guiding opening preferably has a circular, particularly oval or circular cross-section, or a quadrilateral, particularly rectangular or square cross-section. In particular, the contact pin receiving portion is conical along its longitudinal extension and / or surface direction.

[0023] In another embodiment, the first receiving body has an outer extension body extending along the thickness direction, wherein the outer extension body extends away from the printed circuit board body starting from the receiving side and particularly has or extends to a receiving opening. Similar to the previous embodiment in which the inner extension body extends into the printed circuit board body, this embodiment of the outer extension body can, for example, form a sleeve-like protrusion on the printed circuit board by means of the outer extension body, which makes it possible to receive, for example, a contact pin guided from the opposite side of the printed circuit board and having an extended long receiving surface along the thickness direction radially, or for example, a component having an outer extension body can be arranged at a distance from the printed circuit board. In this case, as long as this is advantageous for, for example, the geometric arrangement of the electronic components or ensuring reliable connection, these two embodiments can also be combined with the arrangement of the inner extension body inside the printed circuit board body and the outer extension body outside the printed circuit board body.

[0024] In one embodiment, the inner extension body and / or the outer extension body narrow or close at the end side away from the contact pin. Thus, for example, microscopic debris or microscopic wear generated during the insertion and / or reception of the contact pin can be retained in the respective extension body, thereby not contaminating the printed 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, particularly an adhesive, to increase the mechanical strength. With such a filler, the mechanical strength can be increased purposefully, and in addition, the adhesion of debris or wear is facilitated.

[0026] In order to enable, for example, also a through-connection from one side of the printed circuit board to the other side of the printed circuit board via the contact pin, when the component is simultaneously connected to the printed circuit board via the contact pin, the second receiving body is arranged on the opposite side, wherein the electrical connection between the receiving side and the opposite side occurs through the first receiving body, the second receiving body, and the contact pin received and fixed in the first receiving body and the second receiving body. Thus, additional elements for through-holes on different sides of the printed circuit board can be omitted.

[0027] In another embodiment, the first receiving body and / or the second receiving body are mechanically and / or electrically connected to the printed circuit board body, particularly to the conductor tracks arranged on the printed circuit board body, by means of a soldering process, a screwing process, a pressing process, a riveting process, an adhesive process, and / or by means of a brazing process or another suitable process.

[0028] In order to be able to manufacture the first receiving body, the inner extension body, the outer extension body and / or the second receiving body effectively and advantageously and to be able to provide them, for example, as separate components to a printed circuit board, the first receiving body is a corresponding extension body and / or the second receiving body manufactured by stamping, bending, deep drawing, additive processes, metal (pressure) casting processes, metallization of plastic components and / or machining processes.

[0029] On the other hand, this object is achieved by a method for connecting a printed circuit board according to claim 13. In this case, a printed circuit board is provided, and the contact pin is positioned along the thickness direction at the receiving opening such that the contact pin is positioned ready to contact the receiving opening, and then the contact pin is inserted into the receiving opening, wherein the insertion is carried out along the thickness direction, so that the contact pin is received in the receiving opening and is fixed in the receiving opening, in particular by pressing and / or rotating. Thus, according to the invention, the printed circuit board can be connected via the contact pin.

[0030] In one embodiment, a crimp engagement of a crimping device occurs during the insertion of the contact pin. In particular, the crimping device moves relative to the printed circuit board and engages with the printed circuit board via the contact point.

[0031] On the other hand, this object is achieved by a circuit having a printed circuit board and at least one contact pin according to one of the foregoing embodiments, wherein, according to the above method, the printed circuit board is connected via one contact pin or a plurality of contact pins to form a circuit.

[0032] Such a circuit can be manufactured effectively and advantageously, wherein, in particular, a circuit of a printed circuit board with particularly thin and / or low mechanical load can be connected.

[0033] A "circuit", also referred to as a symbol, is an assembly consisting of a printed circuit board, one or more contact pins and, for example, electronic components, wherein such a circuit is in particular a fully or partially operable electronic unit which can be used, for example, for specific switching or control tasks. Description of the Drawings

[0034] The present invention will be explained in more detail below with reference to embodiments. It is shown:

[0035] Figure 1 a shows a schematic view of a printed circuit board with a push contact in a sectional side view,

[0036] Figure 1 b shows a schematic view of another printed circuit board with a push contact in a sectional side view,

[0037] Figure 2 shows a schematic view of a printed circuit board with a clamp in a sectional side view, and

[0038] Figure 3 A schematic view of an improved printed circuit board with a clamp is shown in a sectional side view. Detailed Description

[0039] As an example, the printed circuit board 101 is shown as part of a circuit for an electronic switching component, for example. The printed circuit board 101 has a substrate 103 made of a glass fiber composite material, on which corresponding conductor tracks 105 and 107 are applied to the upper side 171 forming the receiving side and the lower side 173 forming the opposite side, so that electric current or electrical signals can be conducted. The conductor tracks are made of copper or other conductive metals and / or metal alloys.

[0040] In the substrate, a notch 109 for introducing a push contact 141 is provided along the longitudinal axis 181. Here, the longitudinal axis is arranged along the thickness direction 197 of the printed circuit board 101, and the printed circuit board has a thickness 195.

[0041] A corresponding through-contact connection 111 extends between the conductor track 105 and the conductor track 107 starting from the corresponding connector 113, so that two conductor tracks on two different sides of the printed circuit board 101 are connected to each other.

[0042] At the upper side 171, a receiving portion 131 serving as a receiving body is electrically and mechanically fastened to the conductor track 105 by means of a contact point 121. The receiving portion 131 is formed as a mechanically load-bearing member made of a conductive metal and receives the push contact 141 on a pressing surface 151 arranged in the extension of the notch 109. The push contact 141 has a head 143, wherein the head 143 can be deformed radially with respect to the longitudinal axis 181. By introducing the push contact 141 along the longitudinal axis 131 into a pressing path 185 along the thickness direction 197, the push contact is fastened and fixed in the receiving portion 131 in a force-coupling manner along the pressing surface 151. Thus, through the insertion depth 191, the push contact 141 is electrically connected to the conductor track 105 via the receiving portion 131.

[0043] Similarly (see for this Figure 1b), the pressing contact 161 is received in the notch 110 of the printed circuit board 101. For this purpose, the pressing contact is received in the receiving portion 133 on the lower side 173 of the printed circuit board 101. For this purpose, the receiving portion 133 is arranged on the conductor track 107 on the lower side 173 of the printed circuit board 101 by means of the contact point 123, and is electrically connected and mechanically fixed and fastened. The pressing contact 161 is constructed in a manner similar to the pressing contact 141, has a head 163, and is constructed longer than the pressing contact 141 in order to reach the receiving portion 133 arranged on the lower side 173. Thus, the pressing contact 161 is fastened in the receiving portion 133 along the insertion path 187 of the insertion depth 193.

[0044] It should be mentioned in this regard that, for example, when the receiving portion 131 and the receiving portion 133 are arranged on opposite sides of the notch 209 or 210, a single, longer-constructed pressing contact similar to the pressing contact 141 can be used to make contact between the conductor track 105 and the conductor track 107, so that the through-contact element can be omitted.

[0045] Similar to the previous example, the printed circuit board 201 (see Figure 2 ) has a substrate 203, a conductor track 205 on the upper side 271, and a conductor track 207 on the lower side 273. The printed circuit board 201 has a thickness 295 along the thickness direction 297. Similar to the previous example, a through-contact portion 211 having a joint 213 and a filler 215 is provided. In this case, the receiving portion 231, which also serves as a receiving body, is electrically and mechanically connected and fastened to the conductor track 207 on the lower side 273 by means of the contact point 221. The printed circuit board 201 also has notches 209 and 210. Along the longitudinal axes 281 and 282 defined by the notches 209 and 210, a receiving sleeve 233, which serves as an extension body for receiving the substrate 232 and the receiving portion 231, is arranged on the lower side 273. The receiving substrate 232 is arranged parallel to the conductor track 207 at the lower side 273, and the receiving sleeve 233 extends away from the printed circuit board 201 along the longitudinal axes 281 and 282, that is, along the thickness direction 297. In particular, the receiving sleeve 233 is an external extension body.

[0046] The clamp 241 is guided through the notches 209 and 210. The clamp 241 has an upper part 243 arranged parallel to the surface of the conductor track 201. Then, legs 247 extending parallel to the longitudinal axes 281 and 282 are orthogonally connected to the upper part 243 along the bend 245. The legs 247 are guided through the notches 209 and 210. A crimper 249 arranged inside the clamp 241 between the upper part 243 and the conductor track 205 receives the stranded wire 251 in a form - fitting and electrically conductive manner. Then, the legs 247 are introduced into the receiving sleeve 233 and are received in a force - coupled manner on the pressing surface 261 inside the receiving sleeve 233 in a manner similar to the previous example of the pressing contacts 241 and 261 (going into the image plane in Figure 2 ). Thus, the clamp 241 is fixed at the insertion depth 291 in the receiving part 231 along the pressing path 285 and simultaneously connects the stranded wire 251 to the conductor track 205 and the conductor track 207.

[0047] Here, when the clamp (Crimpschelle) 241 is introduced along the pressing path 285, the crimping engagement of the crimper 249 is achieved or accomplished by guiding the crimper 249 against the printed circuit board 201 and pressing the crimper together by contact with the printed circuit board 201.

[0048] The improved printed circuit board 201 (see Figure 3 ) differs from the printed circuit board 201 shown according to Figure 2 in the orientation and position of the receiving sleeve 233 forming the internal extension body. As the internal extension body, the receiving sleeve 233 extends into the notches 209, 210 in the base body 203 of the printed circuit board 201. The cross - section of the receiving sleeve 233 is substantially the same as the cross - section of the notches 209, 210. Thus, the receiving sleeve 233 abuts against the boundary walls of the notches 209, 210 when a force is applied. In an alternative embodiment, the sleeve can also be received in the notches 209, 210 without a force acting.
