Definitions

  • the invention relates to a connector which can be contacted on the one hand with a circuit carrier such as a printed circuit board and on the other hand is used for the mechanical and electrical connection with a mating connector carrying electrical (signal) lines. Furthermore, the invention relates to a circuit arrangement consisting of a connector according to the invention and a circuit carrier and a method for forming such a circuit arrangement.
  • An electrical connector with the features of the preamble of claim 1 is from DE 10 2017 123 080 A1 known.
  • the well-known plug connector is characterized by a ground connection for the electrical shielding of electrical lines arranged within the plug connector, which is formed, among other things, by an at least partially metallic plug body which is connected to the electrical ground of a circuit carrier via a number of contact elements. It is provided that the contact elements protrude from an end face of the connector body and can be inserted into corresponding insertion openings in the circuit carrier and contacted there with these, for example by soldered connections.
  • the electrical connector according to the invention with the features of claim 1 has the advantage that it enables particularly high-quality and reliable shielding of signal lines routed within the connector body. This is achieved in that any gap formed between a circuit carrier and the connector is bridged or closed by a special design of the pluggable shielding element on the connector body in such a way that an (elastic) spring force can be generated by the at least one contact element on the shielding element press the plug connector or the shielding element and the circuit carrier against one another or press them against one another and thereby ensure a gap-free design in the connection area of the circuit carrier and shielding element.
  • the electrical connector with the features of claim 1 provides that the at least one contact element is designed as a component that is preferably monolithically connected to the shielding element, that the shielding element has an end face for contacting the electrical ground connection on the circuit carrier, and that the at least one contact element is designed to be elastically resilient in an insertion direction serving to connect to the circuit carrier.
  • a particularly preferred structural design of the plug connector provides that the at least one contact element is designed in some areas as a press-in pin, which is connected to the shielding element in a connection area on a side facing away from a press-in section for connection to the circuit carrier, and that the Contact element is arranged longitudinally displaceable in the area between a deformation section and the press-in section in the insertion direction on the connector body.
  • the press-in pin between the deformation section and the press-in section is designed in a straight line and in alignment with the insertion direction of the contact element, and that the contact element is arched and/or curved in relation to the insertion direction in the deformation section .
  • Such a design of the press-in pin makes it possible, in particular, to elastically deform or lengthen the press-in pin in the direction of the circuit carrier by means of a force acting perpendicularly to the insertion direction on the press-in pin in the region of the deformation section, in order to achieve the required contact force of the connector for the press-in pin in the pressed-in state to generate circuit carriers.
  • the deformation section of the press-in pin protrudes laterally beyond the connector body.
  • auxiliary tool which can be placed against the deformation section or the connector body and at the same time deforms the deformation section of the contact element in the desired manner.
  • this also enables a particularly simple, e.g To generate circuit carrier. This can be done, for example, by checking the lateral distance between the deformation section and the plug body or its side wall.
  • the invention includes a circuit arrangement, having a connector according to the invention as described so far and a circuit carrier, in particular in the form of a printed circuit board.
  • the circuit arrangement according to the invention is characterized in that the circuit carrier has an insertion opening connected to electrical ground for a clampable connection to the at least one contact element of the shielding element, and that the circuit carrier has a connection section connected to electrical ground and having a closed outer contour on the side facing the end face has which is arranged in at least partial overlap with the end face of the shielding element and which surrounds the lines arranged in the connector body in the plane of the circuit carrier.
  • connection section is in the form of a solder layer which has a lower Hardness than the end face of the shielding element.
  • connection between the plug connector and the circuit carrier can be formed solely by a mechanical connection, i.e. without soldered connections or similar material connections. This enables a particularly simple assembly process with correspondingly simply designed manufacturing and assembly facilities.
  • the invention also includes a method for forming such a circuit arrangement, the method including at least the following steps. First, the plug connector is aligned with the circuit carrier, so that the at least one contact element is arranged with a press-in section in alignment with the insertion opening of the circuit carrier. Then the plug connector and circuit carrier are moved towards one another in an insertion direction running perpendicular to the plane of the circuit carrier. Thereafter, the end face of the shielding element is brought into contact with the terminal section of the circuit carrier that is connected to electrical ground.
  • a deformation force is applied to the at least one contact element in the area of a deformation section while the connector and circuit carrier are moving towards one another and/or after the contact element has been inserted into the insertion opening of the circuit carrier, or alternatively a contact force is applied to the connector body in a state in which an end face of the shielding element is in contact with the terminal section of the circuit carrier that is connected to electrical ground.
  • the figures show a circuit arrangement 100, which can be part of an electrical device, such as a switching device or control device, for example for motor vehicle applications.
  • the circuit arrangement 100 comprises a circuit carrier 1 in the form of a printed circuit board 2, for example.
  • the connector 10 in turn is used for the electrical and mechanical connection only in the 1 mating connector 5 shown in simplified form with signal lines whose signals or voltages are processed in the area of circuit arrangement 100, for example by means of electronic devices, such as ICs or the like, which are not shown.
  • the connector 10 has a connector body 12 which is made of plastic and is designed as an injection molded part.
  • the connector body 12 also has a shielding element, in particular in the form of a sleeve-like shielding plate 16 .
  • the shielding plate 16, which is preferably designed as a stamped/bent part, surrounds the signal lines 14 within the plug body 12 and is preferably arranged in the (outer) edge region of the plug body 12, as is shown in FIG 3 is recognizable.
  • the material of the plug body 12 is connected to the shielding plate 16 by overmolding it, or, as shown in the figures, by the shielding plate 16 being designed as a separate component that is connected by a form-fitting and/or positive connection with the connector body 12 is connected by an assembly process.
  • connection area 50 a partial area of the printed circuit board 2 is shown in the connection area 50 .
  • metallized insertion openings 18 for four signal lines 14 of the connector 10 in the exemplary embodiment which are electrically conductively connected to the circuit of the printed circuit board 2, which is not shown in detail.
  • the insertion openings 18 are used during the assembly process of the connector 10 which is arranged within the connector body 12 signal lines 14, which correspond to the representation of 2 and 5 to 7 are designed as contact elements 21 in the form of press-in pins 20 on the side facing the printed circuit board 2, and to make electrical contact.
  • the printed circuit board 2 is provided with a solder layer 24 as a connection section 23, which overlaps the cross section of the shielding plate 16 on its end face 22 facing the printed circuit board 2, which layer has a closed outer contour 25 and which additionally separates the insertion openings 18 from one another within the contour 25 or surrounded by distance.
  • the connection section 23 is connected to electrical ground.
  • the material of the solder layer 24 has a lower hardness than the material of the shielding plate 16.
  • the connector 10 is assembled with the circuit carrier 1 or the printed circuit board 2 in an insertion direction 26 running perpendicularly to the circuit carrier 1 plane. It is essential that the shielding plate 16 is also electrically conductively connected to a plurality of contact elements 28, which are also in the form of Press-in pins 30 are formed. The press-in pins 30 protrude beyond the end face 22 of the shielding plate 16 with a press-in section 32 which interacts with an insertion opening 34 in the area of the printed circuit board 2 .
  • contact elements 28 are provided, which are formed in regions as press-in pins 30, of which two contact elements 28 are arranged on a side surface 35 to 37 of the shielding plate 16 or plug body 12, which is rectangular in cross section.
  • the contact elements 28 are integrally connected to the shielding plate 16 in a connection area 38 on the side facing away from the respective press-in section 32 .
  • a deformation section 40 of the contact element 28 adjoins just below the connection region 38 and is bent outwards in a substantially semicircular shape. Outside the deformation section 40, the contact element 28 is straight and runs parallel to the direction of insertion 26. Furthermore, the deformation section 40 of the contact element 28 protrudes beyond the plug body 12 in the area of side walls 41 to 43, so that the deformation sections 40 are easily accessible, for example, for an auxiliary tool.
  • the contact element 28 is supported on both sides of the deformation section 40 at a small distance from the deformation section 40 in relation to the connector body 12, so that a transverse force F ( 6 ) as a deformation force leads to an elastic deformation or elongation of the deformation section 40 in the longitudinal direction of the contact element 28, but not to a deflection of the contact element 28 outside of the deformation section 40 in the direction of the transverse force F or transversely to the direction of insertion 26.
  • the area of the Contact element 28 is arranged to be longitudinally displaceable between the deformation section 40 and the press-in section 32 parallel to or in alignment with the direction of insertion 26, so that when the transverse force F is applied with a corresponding deformation of the deformation section 40, the contact element 28 or the pressing section 32 also extends over the end face by a certain length 22 of the shielding plate 16 protrudes.
  • the contact elements 21 and 28 of the connector 10 are aligned with the insertion openings 18 and 34 of the printed circuit board 2.
  • the connector 10 and circuit board 2 are then moved towards one another, for example by moving the connector 10 in the insertion direction 26 with an assembly force running in the insertion direction 26 and acting on the connector body 12 outside the contact elements 28 .
  • the contact elements 21 and 28 are pressed into the insertion openings 18 and 34 of the circuit board 2 .
  • the circuit carrier 1 or the circuit board 2 rests on a stationary support surface, not shown in the figures.
  • the deformation sections 40 of the contact elements 28 are (elastically) deformed in such a way that the press-in sections 32 are deformed by the extent of the deformation that leads to a Elongation of the contact elements 28 leads, are additionally moved or pressed into the insertion openings 34. Furthermore, when the shielding plate 16 comes into contact with its end face 22 with the connection section 23 of the printed circuit board 2, a plastic deformation of the solder layer 24 takes place. This enables a gap-free transition from the shielding plate 16 on the end face 22 to the connection section 23 or its ground connection.
  • a contact force A is generated by the contact elements 28 via their elastically deformed deformation sections 40 in the direction of the connection section 23 of the circuit board 2, which presses the plug connector 10 against the circuit board 2 and thereby eliminates the gap between the shielding plate 16 and the connection section 23 in the connection area 50 guaranteed.
  • the circuit arrangement 100 described so far can be altered or modified in many different ways without deviating from the idea of the invention. It is also possible for the described connection between the plug connector 10 and the printed circuit board 2 to take place in a different way. For example, it is conceivable not to apply a transverse force F to the contact elements 28 during the assembly process, but to apply a contact force B to the connector 10 running in the direction of insertion 28 after the shielding plate 16 has come into contact with the connection section 23 of the printed circuit board 2, as shown in FIG 6 is shown. As a result, due to the elasticity of the components, an elastic prestressing force is generated on the plug connector 10, which after release of the contact force B leads to a springback of the plug connector 10. However, since the contact elements 28 are inserted relatively deeply into the press-in openings 34, this force leads to a deformation of the deformation sections 40 with a corresponding contact pressure between the connector 10 and the printed circuit board 2.
