Definitions

  • Connectors are well known from the prior art. They are used to create electrical connections between components. In the production of electronic components, plug connectors are used in particular, which are plugged directly into the plug-in zones of a printed circuit board, as is the case, for example, in the applicant's own DE 20 2012 002 501 U1 is shown and described. Alternatively, it is possible to arrange a so-called pin tray on the circuit board. This is a contact carrier mounted on the circuit board, the contacts of which, in particular flat blade contacts, are connected directly to the circuit board.
  • the recording facility according to US 5,800,186 A uses the contacts for a positive fixation on the one hand and a frictional fixation on the other.
  • connectors can be found in many areas of application, from household appliances to use in automotive technology to devices for science and research. If the connectors are designed as direct connectors, they usually hold on to the circuit board in a frictional manner, with the frictional connection being produced by the contact forces between the contact surfaces of the circuit board and the plug contacts of the connector.
  • Direct plug-in connectors are known from the prior art, which cannot be documented in writing, which are provided with locking hooks which engage in locking contours of the circuit board, so that in addition to the The frictional connection caused by the plug contacts also ensures a positive hold of the plug connector on the circuit board.
  • Such connectors are used in particular when the component carrying the connector is subject to vibration movements and the vibrations can lead to the connector becoming detached from its counterpart, in particular the circuit board.
  • Plug connectors with positive fastening to the circuit board require a larger installation space due to the additional holding means, and the circuit board must also be provided with a corresponding holding contour. This is not only disadvantageous from a cost point of view, but also has its limits above a certain level of miniaturization, since the locking structures and the holding contours on the circuit board side have to have certain minimum dimensions in terms of production technology.
  • the object of the invention is therefore to create a plug connector, in particular a direct plug connector, which can reliably withstand high acceleration forces and high vibration frequencies.
  • the connector according to the invention deliberately avoids positive fastening to the circuit board in order to meet all miniaturization requirements and to be as independent as possible from the dimensions of the circuit boards manufactured with comparatively low precision.
  • the invention has recognized that a frictional fastening of the connector on the circuit board has significant advantages in terms of manufacturing and assembly technology. While in the prior art it was generally the case that the hold of the plug connector on its plug-in counterpart basically resulted from the required pressure forces of the plug-in contacts, the clamping means according to the invention allow the holding forces, i.e. the frictional connection between the clamping means and the plug-in counterpart, solely with regard to the Dimension fastening requirements. According to the present invention, the connector is fixed by the contact pressure forces optimized for the electrical transition and by the clamping means's holding forces optimized for the holder on the plug counterpart.
  • the contact zone of a connector defined by the contact tips of the plug contacts is usually comparatively far forward in the plug receptacle, i.e. close to it Plug opening. In this way, sufficient coverage of the contact fields on the mating piece side and the plug contacts of the plug connector is ensured. In the prior art, however, this automatically leads to the fastening zone, i.e. the zone in which the frictional forces holding the plug contact on the plug counterpart act, coinciding with the contact zone and also being arranged close to the plug opening.
  • the clamping means according to the invention make it possible to optimize the position of the holding zones and, according to the invention, to place them deeper in the plug-in receptacle, in particular near the bottom of the plug-in receptacle.
  • the holding zones are then close to the edge of the circuit board. In this way, any vibration behavior of the connector can be influenced particularly favorably.
  • the invention provides that the clamping means is formed by a pair of clamping arms consisting of two opposing clamping arms, which form the clamping gap between them, in particular when the clamping arms are arranged in the plug-in receptacle.
  • the clamping arms have the main advantage that they can be deflected from a neutral position. In view of the considerable thickness tolerances of printed circuit boards compared to the plug-in gap width, any plastic deformation that may be problematic and in any case requires a lot of assembly effort can be dispensed with. If the clamping arms are also spring-return elastic, it not only ensures that the minimum frictional connection between the connector and the circuit board or plug-in counterpart is guaranteed. It is also guaranteed that after the plug connector and plug counterpart have been separated, for example when replacing a circuit board, the minimum system pressure to produce the required frictional connection can be re-established by the clamping arms.
  • the insertion gap and the clamping gap have a common gap center plane, i.e. they are aligned with one another.
  • clamping arms can be deflected in a spring-return-elastic manner.
  • This has the significant advantage that the clamping arms are protected and securely arranged and cannot be damaged during the assembly of the connector or its assembly.
  • These clamping means which are arranged in the plug receptacle within the connector contact carrier, cannot cause any problems in the connector assembly, for example due to two contact carriers moving side by side being caught by the automatic assembly machine.
  • Spring-return elastic clamping arms can be achieved particularly easily in that the clamping arms have a tied end and a free end opposite the tied end, so that the material's own elasticity can act freely. This is particularly advantageous because it is considered that the clamping means are made of the contact carrier material itself, i.e. generally made of plastic material.
  • the contact carrier forms at least one clamping arm chamber in which a clamping arm is seated, in particular each contact carrier wall having a clamping arm chamber, the clamping arm chambers being spaced apart from one another by the clamping gap and a clamping arm in each clamping arm chamber Pair of clamping arms is arranged.
  • At least one clamping arm is connected near the plug-in receiving base and for its free end to extend in the plug-in direction, with a preferred embodiment even provides that a clamping arm connected close to the plug opening and a clamping arm connected near the plug-receiving base lie opposite each other, whereby two fastening zones can be realized on the plug-in counterpart, which in turn has a stabilizing effect on the plug-in connector arrangement.
  • a connector according to the invention is provided with the reference number 10 and is shown in three different embodiments.
  • the Figures 1 to 4 show a connector 10 according to the invention in the first embodiment
  • Figures 5 to 8 show a second embodiment of the connector according to the invention
  • 10 the Figures 9 to 12 show a third embodiment of the connector 10 according to this invention.
  • the connector initially comprises a contact carrier 11, which can be formed in one piece, but in the exemplary embodiments is composed of a contact carrier base 11A and a contact carrier cover 11B, with plug contacts 12 being mounted in the contact carrier 11 between the contact carrier base 11A and the contact carrier cover 11B.
  • the plug contacts 12 each have a clamping section 13, from which two opposing contact legs 14 arise in the plugging direction X.
  • Conductor connection sections 15 arise from the plug contact 12 in the opposite direction to the plug-in direction
  • each plug contact 12 forms a contact gap 16 between them, which serves to accommodate a mating contact, not shown, of a plug counterpart, also not shown.
  • the counter contact can be, for example, contact fields or conductor tracks of a printed circuit board designed as a plug-in counterpart. It is also known to provide contact blades as plug-in counterparts that form contact surfaces. Contact tips 17 formed by the contact legs 14, which point towards one another, ensure a secure contact on the contact surfaces of the plug-in counterpart.
  • the individual plug contacts 12 are arranged next to each other in the contact carrier 11 and aligned in such a way that their individual contact columns 16 Aligned with each other, they form a common receiving gap for a circuit board or contact pins.
  • a clamping arm chamber 20 is formed on the right and left between the side cheeks 19 of the contact carrier cover 11B and the external contact receptacle 18 of the contact receptacle row. This can extend into the contact carrier base 11A through appropriate design, but this is not implemented in the present exemplary embodiments.
  • the Figures 2 , 6 and 10 show the connector 10 of the respective embodiment in the assembled state.
  • the plug contacts 12 are first inserted into the contact receptacles 18 of the respective contact carrier cover 11B, whereupon the contact carrier base 11A is then placed on the contact support cover 11B, so that the individual plug contacts 12 are clamped between the contact support base 11A and the contact support cover 11B.
  • the Figures 3 , 7 and 11 The three embodiments of the invention show an insight into the plug-in receptacle 21 of the respective plug-in connector 10, i.e. onto the end face of the respective contact carrier 11 located at the front in the plug-in direction - viewing direction opposite to the plug-in direction -, the plug-in receptacle 21 being formed by the respective contact carrier cover 11B.
  • the plug receptacle 21 is a material-free device between two opposing contact carrier walls 22 and the Side cheeks 19.
  • the plug-in receptacle 21 forms a plug-in gap 23, which serves to accommodate a plug-in counterpart (not shown) such as a circuit board or contact knife.
  • the plug-in gap width W is adapted to the thickness of the plug-in counterpart, for example the maximum circuit board thickness, so that the plug-in counterpart can be immersed in the plug connector or the plug connector can be pushed onto the plug-in counterpart.
  • the contact gap width K defined by the distance between opposing contact tips 17 of a respective plug-in contact 12, is manufactured with a significant undersize compared to the thickness of the plug-in counterpart in order to ensure secure contacting of the contact tips 17 on the contact surfaces of the plug-in counterpart.
  • the contact gap width K is therefore significantly smaller than the insertion gap width W.
  • each contact leg 14 sits in a leg niche 24 and can be moved in a spring-return-elastic manner transversely to the longitudinal extension of the plug-in gap, i.e. in particular outwards into the respective leg niche 24, so that insertion of the plug-in counterpart into the plug-in gap 23 is possible while deflecting the contact legs 14.
  • Insulating webs 25 are formed between adjacent contact legs 14 of the respective plug contacts 12, which securely space the contact legs 14 apart from one another.
  • clamping means 30 which form a clamping gap 31, the gap width M of which is smaller than the width W of the plug-in gap 23.
  • the insertion gap 23 and the clamping gap 31 as well as the contact gap 16 have at least one common gap plane - not further specified. They can therefore be arranged offset from one another, taking into account at least one common cleavage plane.
  • the contact gap 16 and the clamping gap 31 have a common gap center plane, but in any case to be aligned with one another.
  • the plug-in counterpart When the plug-in counterpart is inserted into the plug-in gap 23, it also dips into the clamping gap 31 and displaces the clamping means 30 from its rest position. The resulting frictional connection between the clamping means 30 and the plug counterpart keeps the latter secure and stable in position.
  • FIG. 4 for the first exemplary embodiment a sectional view according to section line IV-IV in Figure 2 shows a first type of clamping means 30. These are initially formed by a first pair of clamping arms 34 with a first clamping arm 32 and a second clamping arm 33, each clamping arm 32, 33 being arranged on the contact carrier 11 near a plug-in receiving base 26 and so in the plugging direction X of the Plug contact 12 enters the plug receptacle 21.
  • clamping arms 32, 33 of the first pair of clamping arms 34 are formed by the contact carrier base 11A. They are connected at one end to the contact carrier base 11A and extend from there in the insertion direction X or in the direction of the contact carrier cover 11B into its clamping arm chamber 20.
  • the clamping arms 32, 33 are designed to be spring-return-elastic, so that they can each be deflected outwards, away from the center plane of the plug-in gap (not shown).
  • the clamping means 30 of the first embodiment are then supplemented by a second pair of clamping arms 35 with a third clamping arm 36 and a fourth clamping arm 37, which form the clamping gap 31 between them.
  • the third clamping arm 36 as well as the fourth clamping arm 37 originate near a plug-in opening 27 of the contact carrier 11, through which the plug-in counterpart dips into the plug-in gap 23, and are consequently formed by the contact carrier cover 11B. They extend counter to the plug-in direction
  • the main advantage of this embodiment is that a circuit board seated in the plug-in gap 23 or an alternative plug-in counterpart is held particularly stable, especially if transverse forces cause the plug connector to tilt or swing about an axis parallel to the plug-in gap.
  • the diametrically opposed clamping arms 36, 33 and 37, 32 reliably absorb the respective tilting movement.
  • the lever forces exerted on the respective clamping arm 36, 33 or 37, 32 are particularly low due to the opposite connection of the respective clamping arm 36, 33 or 32, 37. Since each pair of clamping arms 35, 34 has a fastening zone with the plug-in counterpart, in particular a circuit board, i.e. there are two contact zones one behind the other and spaced apart from one another in the insertion direction
  • FIG. 8 a sectional view according to section line VIII-VIII in Figure 6 now shows the clamping means 30 of the second embodiment of the invention, which are also seated in the clamping arm chamber 20 there.
  • the clamping means 30 is formed by a pair of clamping arms, the third pair of clamping arms 38, the opposing clamping arms 39 of which form the clamping gap 31 between them.
  • the respective clamping arm 39 of the third pair of clamping arms 38 is connected to the contact carrier 11, more precisely to the contact carrier cover 11B, close to the plug opening and extends against the plugging direction Frictional connection between the plug-in counterpart, in particular the circuit board, and the contact tips 17 of the plug-in contacts 12, a further frictional zone is formed by the contact between the clamping arms 39 and the plug-in counterpart.
  • the contact zone of the clamping arms 39 is close to the plug base compared to the position of the contact tips 17 and thus reduces the force vector available for oscillating movements of the plug contact 10.
  • Figure 12 is a sectional view of the contact carrier 11 according to section line XII-XII in Figure 10 acts.
  • the fourth pair of clamping arms 40 found here with its opposing clamping arms 41, which form the clamping gap 23 between them, in turn extends into the plug-in gap 23.
  • the clamping arms 41 sit in the respective clamping arm chamber 20. They have a connection to the contact carrier 11, more precisely the contact carrier base 11A in the area of the plug-in base 26. Their free end is located in the plug-in direction X and extends in the direction of the contact-carrier cover 11B or plug-in opening 27.
  • a contact zone downstream of the contact tips 17 in the plugging direction is formed, so that the transverse forces causing the plug connector 10 to vibrate can be safely absorbed.
  • clamping means 30 Another possibility for creating clamping means 30 is also shown. These are clamping ribs 50, which are applied to the insulating webs 25. This is particularly the case Figures 3 , 7 and 11 refer to. Even if this embodiment is shown here exclusively in combination with clamping arms, in a technical development that is not based on the present invention, the clamping means 30 can also be formed exclusively by clamping ribs 50 which extend into the plug-in gap 23. With these Clamping ribs 50 do not provide for resilient deflection. Instead, when a plug-in counterpart, such as a circuit board, is inserted, these will deform plastically and thus create the frictional connection.
  • clamping means 30 whether designed as a clamping rib or a pair of clamping arms, can also be arranged on the outside of the side cheek 19 and do not necessarily have to be located in the plug-in gap 23.
