Presentation of the invention

It is an object of the present invention to provide a rugged receptacle for printed circuit boards which conforms to exact geometry specifications.

This object is achieved with a plug socket for planar carriers with an arrangement, with a semi-finished of a bendable metal plate and with a method for producing a plug socket for planar carrier according to the independent claims.

According to a first aspect of the present invention, a socket for planar carrier, in particular printed circuit boards is described. The socket has a support portion extending from the support portion extending contact carrier for holding a connector pin, and starting from the support portion extending contacting elements for electrically conductive contacting the planar support. The support portion, the contact carriers and the contacting elements are machined from a common stamped and partially bent metal plate (i.e., a plate portion), and the support portion lies in the plane of the metal plate.

According to a further aspect of the present invention, an arrangement is provided which comprises a planar carrier, in particular a printed circuit board, and a socket as described above. The planar support has a fastening region for fastening the contacting elements of the socket.

According to a further aspect of the present invention, a semi-finished product of a bendable metal plate is provided for producing a female connector as described above. The semifinished product can be bent along at least one bending line, so that the socket described above can be produced by bending the semifinished product.

According to a further aspect of the present invention, a method for producing a plug socket for planar carriers, in particular printed circuit boards, is provided. The method comprises providing a metal plate. According to the method, the metal plate is machined, in particular stamped, such that a support portion, extending from the support portion extending contact carrier for holding a connector pin and starting from the support portion extending contacting for electrically conductive contacting the planar support are formed. Furthermore, at least the contact carrier is bent out of a plane of the metal plate in such a way that at least the support section lies in the plane of the metal plate.

The socket is designed to secure an electrical or electronic connector by means of the contact carrier. The female connector is made integral and monolithic from a provided metal plate. In other words, the socket is integrally formed.

The planar carrier has, for example, a plurality of electrical components and / or printed conductors, which are to be electrically connected via the socket with a plug. The planar carrier represents in this regard For example, a printed circuit board, such as a printed circuit board (PCB). The plug, or plug pin, can be designed as a round plug, as a flat plug, as a 4-kantstecker or polygonal connector. Further, the plug may have a post made of drawn wire (eg, 0.63mm in diameter).

The metal plate forms a thin metal sheet or metal sheet, which can be deformed or bent non-destructively. The metal plate is accordingly made of an electrically conductive material. The metal plate can also be partially surface-finished. For example, the contact carrier and the contacting elements may be free of a surface finish, while, for example, the support section surface-finished, for example tinned, galvanized or galvanized is. The contact points can also be made from a pre-finished band. In particular, the metal plate is made of highly flowable and bendable material, e.g. made of copper, aluminum, silver, gold or alloys such as brass or bronze. The metal plate may have a thickness between 0.1 mm and 2 mm.

The support section forms the base element from which the contact carriers and the contacting elements extend. The support portion is part of the metal plate and continues to be in the same plane of the metal plate even after the bending of the contact carriers and / or the contacting elements. In other words, the support portion is not deformed and maintains the same plane of the metal plate.

The support section can have a continuous material region or can have a central passage opening, which can be inserted, for example, by means of drilling or punching. The inner diameter or the shortest distance between two opposite sides of the passage opening adjoining the passage opening may, for example, be 6 mm to 10 mm, in particular 8 mm. The outer diameter or the shortest distance between two opposite outer sides of the support section may, for example, 8 mm to 12 mm, in particular 10 mm, have The passage opening can be circular, elliptical or polygonal, for example, square or hexagonal. The support portion may be formed as a support ring with a radially outer circumferential outer surface or outer contour. The support portion may have a round radial outer surface or outer contour. Further, the support portion may have a circumferential outer surface or outline which is in the form of a polygon, i. with a polygonal outer surface (e.g., square or octagon). The outer surface thus forms the outer edge or the circumferential surface of the support portion.

Further, the surfaces of the metal plate form the surfaces of the support portion. Correspondingly, the support section has a, in particular planar, support surface, which is intended to lie flat on a surface (i.e., mounting plane) of the planar support. The support portion or its support surface is thus parallel to the mounting plane of the planar support. The diameter or the shortest distance between two opposite sides of the support section is, for example, 0.5 mm to 2 mm, in particular 1 mm (millimeters).

The contact carriers are arranged in the circumferential direction of the support portion and extend first from an inner surface of a through hole of the support portion or outer surface of the support portion and then extend out of the plane of the metal plate. The contact carriers thus form a socket or close a clamping or receiving area, in which a plug can be received and held. The contact carriers are elastically deformable after bending out of the plane of the metal plate. Thus, for example, a plug can be inserted between the contact carrier, so that the contact carrier elastically deform outwardly and thus acts a clamping force on the plug and a clamping connection can be created. The contact carriers form so-called spring plates.

The contacting elements form an electrically conductive contact with the planar carrier. The contacting elements are arranged in the circumferential direction of the support portion and initially extend from a circumferential inner surface or circumferential outer surface of the support portion. Depending on the method of connection to the planar support, the contacting elements, as described below, may extend along the plane of the metal plate or be bent out of the plane of the metal plate. The contacting elements have for example a length of 2 mm to 4 mm.

The metal plate is a semi-finished product in the initial state. The semifinished product can first be cut, drilled and / or punched in order to produce the basic shapes of the support section, the contact carrier and / or the contacting elements. The semi-finished product is then bent over a defined bending line so that after bending the socket is present. The bending line can for example be perforated or embossed, in particular, the bending line can provide a desired bending point to which the semifinished product can preferably be deformed in particular plastically.

The socket according to the invention is due to the arrangement of the contact carrier and the contacting elements on the support portion made in one piece, so that the socket is extremely robust. Additional fasteners between adjacent edges of the socket are not present, so there are no critical breaks. At the same time can be made extremely simple and economical by means of the inventive design of the socket, that after the machining or punching of the metal plate only a bending process must be performed. Further fixing steps, such as the connection of abutting edges, for example by means of plug contacts or solder / weld connections, are not necessary with the plug socket according to the invention.

According to a further exemplary embodiment, the support section has a circumferential outer side, wherein the contacting elements extend from the circumferential outer side.

According to an exemplary embodiment, the support section has a passage opening in the interior. An inner circumferential part around the through-hole and the outer circumferential side of the support part along a radial direction, which are e.g. extends through the center of the support portion, form opposite surfaces or sides of the support portion.

In the described exemplary embodiment, the contacting elements extend from the circumferential outer side of the support portion. In an alternative embodiment, the contacting elements may also extend from the circumferential inner side of the support portion and protrude, for example, from the circumferential inner side toward the center of the support portion.

According to a further exemplary embodiment, the contact carriers extend from the circumferential outer side. The contact carriers are formed so to speak on the circumferential outer side and protrude from this. After forming the contact carriers on the circumferential outer side, the contact carriers are correspondingly deformed from the plane of the metal plate, thus forming the socket.

According to a further exemplary embodiment, at least one of the contacting elements is present in a support section plane of the support section. The contacting elements can be soldered and / or glued in particular to the planar carrier. The contacting elements are formed for example by means of punching and then not further bent, so that the contacting elements do not extend further from the plane of the metal plate or the mounting plane of the planar support but remain in the planes. Accordingly, the contacting elements on a support surface for resting on the planar support. The bearing surface of the contacting elements is located for example in the same plane as a bearing surface of the support portion. Thus, the contacting elements can be fixed, for example by means of an adhesive bond or by soldering to the planar support. Accordingly, the contacting elements or the socket can be conductively connected to the planar carrier by means of surface-mount technology (SMT).

According to a further exemplary embodiment, at least one of the contacting elements is bent relative to a support section plane (which corresponds in particular to the plane of the metal plate) of the support section to the same side as the contact carriers. In other words, the contacting elements and the contact carriers leave the support section plane in which the support section is present and extend from this support section plane in the same direction. Thus, it is possible with the socket to implement a so-called substructure variant with external board contact. For example, the planar carrier has a passage opening. The receptacle may be disposed on the planar support such that the support portion rests on a surface of the planar support and the contact carriers extend through the throughbore. Accordingly, the contacting elements are fastened in fastening openings of the planar support. The support portion thus rests on a surface of the planar support and the contact carriers extend through the planar support and away from an opposing surface. Thus, a robust attachment of the socket to the planar support can be made possible.

According to a further exemplary embodiment, at least one of the contacting elements is bent relative to a support section plane of the support section on the opposite side as the contact carrier. In other words, the contacting elements and the contact carriers leave the support section plane in which the support section is present, and extend from this support section plane in the opposite direction. Thus, with the socket allows to implement a so-called Aufsitzvariante with external board contact. The receptacle may be disposed on the planar support such that the support portion rests on a surface of the planar support and the contact supports extend away from the planar support. The Contacting elements are fastened in fastening openings of the planar support. The support portion thus rests on a surface of the planar support and the contact carriers extend from the same surface of the planar support.

In a further exemplary embodiment, a part of the contacting elements are bent relative to a support section plane of the support section on the opposite side as the contact carrier and another part of the contacting against a support section plane of the support portion bent on the same side as the contact carrier. In addition, additionally or alternatively, the contacting elements may be present in a support section plane of the support section.

According to an exemplary embodiment, at least two of the contacting elements are bent relative to a support section plane of the support section on the opposite side as the contact carrier. At least one further contacting element is bent relative to a support section plane of the support section on the same side as the contact carrier and / or at least one further contacting element is present in a support section plane of the support section. Since at least two of the contacting elements are bent out of plane, and e.g. can be plugged into a non-plated through holes, the stability of the socket is increased, especially against torsional forces.

According to a further exemplary embodiment, the contacting elements are designed such that the contacting elements can be soldered to the planar carrier.

According to a further exemplary embodiment, the contacting elements are designed such that the contacting elements are reversibly pluggable in the planar carrier. By reversibly pluggable is meant a repeatable attachment of the socket to the planar support. A release of the socket is accordingly nondestructive, d. H. without damaging the contacting, allows. For example, a reversible releasable attachment of the contacting elements can be made possible via a press contact of the contacting elements in a mounting opening of the planar carrier.

According to a further exemplary embodiment, at least one contacting element consists of two mutually elastically deformable spring pins. The two spring pins are arranged opposite to each other and can be elastically deformed in the direction of each other. At least one of the two spring pins is elastically deformable relative to the support portion independently of each other and arranged such that when the spring pins are inserted into the mounting opening of the planar support, a plug connection of the socket with the planar support is provided. The term "elastically deformable" refers in particular to a spring pin or a material of the spring pin, which undergoes a functionally not insignificant change in shape with external force, which completely or partially regresses upon release of the external force, so that the elastically deformable material then again completely or partially in the original form (initial form) goes back. With the elastic deformability of the spring pins they can be compressed, for example, during insertion into the mounting hole. After insertion of the spring pins into the mounting aperture, the elastically deformed spring pins attempt to return to their original position and are prevented by the inner wall of the attachment thereto. The force which attempts to bring the spring pins to their starting position is transmitted to the planar support by the spring pin resting on the inner surface of the attachment opening. This creates a force which results in high friction and pressing force and provides the mating connection (e.g., press fit) of the spring pins to the mounting aperture.

The spring pins may further comprise on their outside projections or barbs which are designed to hook with the planar support after insertion of the contact elements in the mounting hole to provide a resistance against the insertion of the socket.

Alternatively, the contacting elements are designed such that the contacting elements are non-releasably pressable into the planar carrier.

According to a further exemplary embodiment, the contacting elements and the contact carriers are formed around the support portion alternately to each other. In other words, the contacting elements and the contact carriers are arranged alternately to one another along a circumferential direction about the support section. Alternatively, for example, groups of contacting elements and groups of contact carriers along the circumferential direction of the support section can be arranged alternately and alternatively to one another. For example, in each case groups of 2 or 3 contacting elements and 2 or 3 contact carriers can be arranged alternately to one another.

According to a further exemplary embodiment, the contact carriers have a first region and a second region, wherein the Contact carrier with the first region extending from the support portion and the second region each having a free end of the contact carrier.

According to another exemplary embodiment, the first area in the circumferential direction of the support portion is wider than the second area. In other words, the foot area, i. H. the first region, which extends from the support section and which, for example, comprises the region of the bending or deformation of the contact carrier, is wider and therefore more robust than a further, second region which, for example, comprises the free end. The free end is in particular designed to enter into a clamping connection with the plug pin to be fastened. In particular, with the narrower second region, a lighter deformation or higher elasticity can be provided in comparison with the further first region. The first area is thus more robust while the second area is elastically deformable.

According to a further exemplary embodiment, the contact carriers are designed such that at least a region of one of the contact carriers extends in the direction of the interior of the support section. In other words, a profile of a portion of a contact carrier has a directional component corresponding to the (e.g., radial) direction to the center of the support portion. For example, the area may be defined between the first area and the second area.

According to a further exemplary embodiment, the contacting elements have a further first region and a further second region. The contacting elements extend with the further first region of the support section and the further second region a free end of the contacting elements. The further first region has a smaller width in the circumferential direction of the support section than the further second region. Thus, there is the possibility that in the first area, which is close to the support portion, there is a narrow area of the contacting element. This simultaneously allows a wider first region of the adjacent contact carrier. The wider further second region of the contacting element has a larger contact surface with the planar carrier than the smaller further first region of the contacting element. Thus, a better contact between the socket and the planar carrier can be achieved.

According to a further exemplary embodiment of the arrangement, the planar carrier has attachment openings for receiving the contacting elements of the socket. The attachment openings can be formed for example by means of drilling. Furthermore, the attachment openings may be coated on their insides with a conductive material, so that in addition to the mechanical attachment of the contacting elements also an electrically conductive connection is provided.

According to a further exemplary embodiment, the planar carrier has a passage opening, which is designed in such a way that the contact carriers of the plug socket can be pushed through the passage opening. With this embodiment, the substructure variant described above with external board contact is possible.

It should be noted that the embodiments described herein represent only a limited selection of possible embodiments of the invention. Thus, it is possible to suitably combine the features of individual embodiments with one another, so that for the person skilled in the art with the variants of embodiment that are explicit here, a multiplicity of different embodiments are to be regarded as obviously disclosed.

Detailed description of exemplary embodiments

The same or similar components in different figures are provided with the same reference numerals. The illustrations in the figures are schematic.

1 shows a perspective view of an exemplary embodiment of a socket 100 for planar carriers 200 , in particular printed circuit boards. 2 shows a side sectional view of the socket 100 out 1 which are on the planar support 200 is attached. The socket 100 has a support section 101 , starting from the support section 101 extending contact carrier 102 for holding a connector pin 310 , and starting from the support section 101 extending contacting elements 103 for electrically conductive contacting of the planar support 200 on. The support section 101 , the contact carrier 102 and the contacting elements 103 are from a common stamped and partially bent metal plate 601 worked out and the support section 101 lies in the plane of the metal plate 601 , The support section 101 is formed in the exemplary embodiment shown as a support ring.

For a better overview, only one contact carrier is shown in the figures 102 and a contacting elements 103 including their different areas have been provided with reference numerals.

The socket 100 is designed to be an electrical or electronic connector 310 (please refer 3 ) by means of the contact carrier 102 to fix. The socket 100 becomes integral and monolithic from a provided metal plate 601 (please refer 6 ) manufactured. In other words, the socket 100 formed in one piece.

The planar carrier 200 For example, has a plurality of electrical components and / or traces, which via the socket 100 with a plug 310 to be electrically connected. The planar carrier 200 represents in this regard, for example, a printed circuit board, such as a printed circuit board (PCB).

The support section 101 forms the base element of which the contact carrier 102 and the contacting elements 103 extend. The support section 101 is part of the metal plate 601 and is also after bending the contact carrier 102 and / or the contacting elements 103 still in the same plane of the metal plate 601 in front. The support section 101 points centrally inside 108 a passage opening. Further, the surfaces of the metal plate 601 the surfaces of the support section 101 , Accordingly, the support portion has a, in particular planar, bearing surface 101 which is intended to be on a surface (ie mounting plane) of the planar support 200 plan to rest. The support section 101 or its support surface is thus parallel to the mounting plane of the planar support 200 in front.

The contact carriers 102 are in the circumferential direction of the support portion 101 arranged and initially extend from a radial or circumferential outer surface 105 , of the support section 101 and then run out of the plane of the metal plate 601 out. The radial circumferential inner surface 104 shows with its normal to the center of the support section 101 , The contact carriers 102 thus form a socket or close a clamping or receiving area, in which also a plug 310 can be recorded and held.

The contacting elements 103 form an electrically conductive contact to the planar support 200 , The contacting elements 103 are in the circumferential direction of the support portion 101 arranged and extend first from the radial outer surface 105 of the support section 101 ,

The contact carriers 102 and the contacting elements 103 protrude from the radial outside 105 of the support section 101 out. After the connection area of the contact carrier 102 on the radial outside 105 become the contact carriers 102 accordingly from the plane of the metal plate 601 deformed and thus form the socket 100 ,

The contacting elements 103 are in the exemplary embodiment in 1 and 2 in a support section plane of the support section 101 in front. The contacting elements 103 For example, they are not bent further so that the contacting elements 103 not further from the plane of the metal plate 601 or the mounting plane of the planar support 200 extend but remain in the planes. Accordingly, the contacting elements 103 a support surface for resting on a mounting area 202 of the planar carrier 200 on. The bearing surface of the contacting elements 103 is for example in the same plane as a support surface of the support section 101 , Thus, the contacting elements 103 for example by means of an adhesive bond or by soldering to the planar support 200 be fixed.

The contacting elements 103 and the contact carriers 102 are around the support section 101 alternately formed to each other.

The contact carriers 102 have a first area 106 and a second area 107 on, with the contact carriers 102 with the first area 106 from the support section 101 extend out and the second area 107 in each case a free end of the contact carrier 102 having. The first area 106 can in the circumferential direction of the support portion 101 be wider than the second area 107 , In other words, the foot area is the first area 106 extending from the support section 101 extends and which, for example, the region of the bending or deformation of the contact carrier 102 comprises, wider and thus more robust than a farther remote second area 107 which includes, for example, the free end.

In the second area 107 for example, a pinching area 204 be formed, which the pin 310 pinched.

The contact carriers 102 are formed such that at least one area 201 one of the contact carriers 102 in the direction of the interior or ring interior 108 of the support section 101 extends. In other words, a course of an area indicates 201 a contact carrier 102 a directional component, which is the radial direction to the center of the support portion 101 equivalent. The area 201 for example, between the first area 106 and the second area 107 To be defined.

The contacting elements 103 another first area 109 and another second area 110 on. The contacting elements 103 extend to the other first area 109 from the support section 101 and the other second area 110 a free end of the contacting elements 103 on. The other first area 109 points in the circumferential direction of the support portion 101 a smaller width than the other second area 110 , Thus, there is a possibility that in the first area 109 which is close to the support section 101 lies, a narrow portion of the contacting element 103 is present. This allows a wider first area at the same time 106 of the adjacent contact carrier 102 , The wider second area 110 of the contacting element 103 points towards the smaller further first area 109 of the contacting element 103 a larger contact area with the planar support 200 on. Thus, a better contact between the socket 100 and the planar carrier 200 be achieved.

The planar carrier 200 has a passage opening 203 through which, for example, an area of the connector pin 310 can be passed.

3 shows an arrangement 200 with a socket 100 as Aufsitzvariante on a planar carrier 200 according to an exemplary embodiment of the present invention.

Further, a connector pin 310 shown which between the contact carrier 102 can be trapped. In particular, the contact carriers 102 a pinching area 204 which is formed to, for example, in clamping contact with a Einklemmnut 311 of the connector pin 310 to stand. The contact carriers 102 are after bending out of the plane of the metal plate 601 elastically deformable. For example, the connector pin 310 between the contact carriers 102 be pushed, so that the contact carrier 102 deform elastically to the outside and thus a clamping force on the pin 310 acts and a clamp connection can be created.

The contacting elements 103 are opposite a support section plane of the support section 101 bent on the opposite side as the contact carrier 102 , In other words leave the contacting elements 103 and the contact carriers 102 the support section plane in which the support section 101 is present, and extend from this support section plane in the opposite direction. Thus, with the socket 100 allows to implement a so-called Aufsitzvariante with external board contact. The socket 100 can be attached to the planar carrier 200 be arranged such that the support portion 101 on a surface of the planar support 200 rests and the contact carrier 102 from the planar carrier 200 extend. The contacting elements 103 For example, in mounting holes 301 of the planar carrier 200 attached.

The mounting holes 301 are coated on their insides with a conductive material, so that in addition to the mechanical attachment of the contacting elements 103 also an electrically conductive connection is provided.

4 shows an arrangement with a socket 100 as a substructure variant with respect to a planar support 200 according to an exemplary embodiment of the present invention. The contacting elements 103 are opposite a support section plane (which in particular the plane of the metal plate 601 corresponds) of the support section 101 bent on the same side as the contact carriers 102 , In other words leave the contacting elements 103 and the contact carriers 102 the support section plane in which the support section 101 is present, and extend from this support section plane in the same direction. Thus, with the socket 100 makes it possible to implement a so-called substructure variant with external board contact. For example, the planar carrier 200 a passage opening 203 on. The socket 100 can be attached to the planar carrier 200 be arranged such that the support portion 101 on a surface of the planar support 200 rests and the contact carrier 102 through the through hole 203 extend through.

Accordingly, the contacting elements 103 in mounting holes 301 of the planar carrier 200 attached. The support section 101 thus lies on a surface of the planar support 200 on and the contact carriers 102 extend through the planar carrier 200 and away from an opposite surface.

5 shows a socket 100 with spring pins 501 . 502 according to an exemplary embodiment of the present invention.
