Definitions

  • the invention is based on a printed circuit card connector with a shield element according to the preamble of independent claim 1.
  • the invention is based on a method for assembling the aforementioned printed circuit card connector according to the preamble of the independent method claim 9.
  • Such shield elements are required in order to connect a metallic housing and a shield cross of the circuit card connector to one another in an electrically conductive manner.
  • the pamphlet FR 2 921 522 A1 discloses a connector for internet cables. This has a cylindrical insulating body with eight inner channels. In each of these channels an Ethernet cable and a contact are arranged that they extend in each channel. The channels are arranged in pairs, each channel pair being separated from the adjacent channel pair by a longitudinal layer of conductive material. The layer is formed by two plates arranged crosswise to form four mutually shielded areas, each with a pair of channels.
  • the pamphlet EP 3 048 675 A1 is based on a socket arrangement with a shielded socket for printed circuit boards or printed circuit boards, which is integrated in a flange.
  • a shielded socket for printed circuit boards or printed circuit boards, which is integrated in a flange.
  • the publication proposes to provide a contact for the shielding with a larger tolerance range that the shielding plate brings about contacting both in radial alignment and in axial alignment with the flange in the inserted state in the contact carrier by means of contact elements designed as spring strips.
  • the pamphlet DE 10 2010 051 954 B3 shows a circular connector which is provided on the connection side for contacting a printed circuit board.
  • electrical contacts are arranged in pairs in the connector.
  • an electrically conductive shield cross connected to at least one ground connection on the printed circuit board is provided. This is surrounded by a likewise cross-shaped contact carrier, in the inclined inner edges of which there are receiving grooves for holding the electrical contacts.
  • the electrically non-conductive round body is pushed over this cross-shaped arrangement and is in turn surrounded by an electrically conductive connector housing.
  • the insulating round body has a circumferential groove approximately in the middle of its length, into which an annular groove electrically conductive spiral spring is inserted. This can, on the one hand, make electrical contact with the screen cross at its latching protrusions through two mutually opposite longitudinal slots of the round body.
  • the spiral spring can contact the connector housing that surrounds the round body and electrically shields it.
  • the connector housing can be built into an electrically conductive device housing in the form of a front panel insert and can be plugged into an externally supplied mating connector.
  • the shield connection via the said spiral spring causes relatively high assembly forces when the electrically conductive connector housing is plugged on. Furthermore, the conductive behavior of the spiral spring is not optimal due to the relatively small electrical contact area with respect to the connector housing and the cross shield.
  • the structural necessity of the circumferential annular groove can also have a disadvantageous effect on the stability and the space available on the round body for other structural details.
  • the publication suggests for improvement DE 10 2012 105 256 A1 suggest the use of an open spring washer.
  • the spring washer has a suitable contour in order to make electrical contact on the one hand with the shield cross and on the other hand a connector housing into which the insulating body is inserted and thereby to connect it in an electrically conductive manner.
  • the object of the invention is therefore to provide an easily mountable and electrically conductive shield connection between the electrically conductive connector housing and the shield cross, which can also be produced as cost-effectively as possible.
  • the latter is particularly advantageous because the shield element connects the connector housing with the shield cross over a large area in this way and thus with a particularly good electrical conductance in an electrically conductive manner.
  • This arrangement also has the advantage that it is easy to assemble.
  • the screen element cannot tilt during assembly.
  • the housing can be plugged onto the connector with little force.
  • the shield connection has a very good electrical conductivity both in relation to the connector housing and in relation to the shield cross.
  • the shield element has only a low ohmic contact resistance in both directions, because, due to their shape and elasticity, the tabs attack the cross shield over a large area on the one hand and the connector housing over a large area and attach themselves elastically to it.
  • the shield element has at least two, preferably at least three and in particular four inwardly pointing, resilient tabs for making electrical contact with the shield cross.
  • this is very useful because of the given shape of the cross shield and the insulating body.
  • such a multiple ground connection is particularly advantageous for high-frequency applications.
  • the shield element can have two or three or also at least four, i.e. four, five, six, seven, eight or even more than eight outwardly pointing resilient tabs for contacting the connector housing.
  • the shield element has four outwardly pointing tabs.
  • the large number of outward-facing tabs e.g. preferably four, is also advantageous for the derivation of high-frequency interference signals.
  • This derivation of high-frequency interference signals is particularly effective when the inwardly pointing tabs and / or the outwardly pointing tabs are each arranged at equidistant intervals on the ring.
  • the shield element is formed from a sheet metal lying in the plane of the ring, preferably punched out of it.
  • the shield element can be a stamped and bent part.
  • the sheet metal is advantageously electrically conductive.
  • the sheet metal has elastic properties.
  • plug-on side plugging is to be understood here as meaning that the shielding element is plugged onto the insulating body via the plug-in area.
  • the connector housing can be plugged onto the insulating body with only a small amount of force. This is of considerable importance in practice, e.g. in device engineering.
  • a printed circuit board with several connectors is built into a device housing.
  • a whole series of insulating bodies can be attached to an edge of a printed circuit board, for example, and can be inserted together with this printed circuit board into connector housings that are already built into a front side of a device housing.
  • an entire array of populated insulating bodies can also be distributed over the surface of the printed circuit board in order to be pushed together into the associated connector housings, which are arranged, for example, in an upper side of the device housing.
  • the corresponding assembly forces add up, so that the circuit board with a larger number of e.g. at least two, three, four, five, six, seven or even eight or even more connectors, e.g. nine, ten, eleven, twelve, thirteen, fourteen , fifteen or at least sixteen connectors, is loaded with correspondingly high forces and mechanical stresses during this insertion process.
  • the manual effort is relatively large.
  • the increase in the conductance of the ground connection of each individual connector housing also improves the ground connection of the device housing, to which the individual connector housings are preferably electrically connected due to their installation.
  • the large number of plug connectors can of course also result in a highly conductive ground connection of the printed circuit board if the device housing is grounded externally, for example via a ground contact, e.g. a grounding screw, e.g. via its power supply.
  • the Fig. 1a shows an open spring ring 7 corresponding to the state of the art. Its contour is clearly recognizable as a meander-shaped open ring.
  • the Figure 1b shows an insulating body 2 'in a first embodiment, in which the insulating body 2' has a largely circumferential, unspecified groove.
  • the spring ring 7 is arranged in this groove. Due to its meandering shape, the spring ring 7 protrudes in sections beyond the insulating body 2 'and in sections engages in its connection-side slots in order to make electrical contact with the cross shield 31 arranged in the insulating body 2'.
  • the areas of the spring ring 7 protruding beyond the insulating body 2 ' can be contacted by a metallic connector housing 4 plugged onto the insulating body 2'.
  • the open spring ring 7 can be elastically deformed under the action of the connector housing 4 in order to be pressed inwards against the cross shield 31 with increased pressure.
  • the Figure 1c shows a printed circuit board 5 with a plurality of insulating bodies 2 ′ mounted on it, equipped with the shield cross 31 and socket contacts (not shown here), which are intended to be inserted into the associated connector housing 4.
  • Said connector housings 4 are suitably mounted on a separately shown housing wall 6 of a device housing for this purpose.
  • the connector housings 4 each consist of an electrically conductive material and are also electrically conductive with the conductive device housing / the electrically conductive housing wall 6 connected.
  • the electrical contact that occurs when plugging together via the spring ring 7 and the shield cross 31 to the ground connections of the circuit board 5 thus also ensures an electrically conductive connection between the circuit board 5 and the device housing.
  • the Fig. 2a shows a spring element 1 according to the invention. It comprises a ring 13 on which four inwardly pointing tabs 11 and four outwardly pointing tabs 12 are molded.
  • the shield element 1 is designed as a stamped and bent part, ie it can be formed, for example, from an electrically conductive, resilient sheet metal, for example stamped out, which lies in the plane of the ring.
  • the Figure 2b shows an associated insulating body 2, which is equipped with the shield cross 31 and socket contacts 33, which are not visible in this illustration, and which is mounted on a printed circuit board 5.
  • the insulating body 2 has an essentially cylindrical connection area 202 on the connection side. Opposite it has a likewise essentially cylindrical plug-in area 201, the diameter of which is smaller than the diameter of the connection area 202. This creates a circumferential step 203 in the transition from the plug-in area 201 to the connection area 202, which is not designated in this illustration for reasons of clarity.
  • connection area 202 is divided into four uniform segments 22 by two cross-shaped slots 21, each of which has two through openings 23 for receiving a socket contact pair per segment 22, the through openings 23 running through the entire insulating body 2.
  • the cross shield 31 is mounted on the connection side on the printed circuit card 5 and is connected in an electrically conductive manner to at least one ground connection of the printed circuit card 5.
  • the shield cross 31 extends through the connection area 202 into the plug-in area 201 of the insulating body 2 and engages there in its cross-shaped slots 21.
  • the insulating body 2 also has two opposite, unspecified slot-like openings on the connection side, one of which is visible in the drawing and through which a connection-side area of the cross shield 31 can be clearly seen.
  • the shielding element 1 is plugged onto the insulating body 2 via the plug-in area 201, so that the ring 13 of the shielding element 1 is arranged on the step 203 of the insulating body 2.
  • the ring 13 has an outer diameter that is smaller than the diameter of the connection area 202 and an inner diameter that is greater than the diameter of the plug area 201.
  • the inwardly pointing tabs 11 of the shield element 1 engage in the cross-shaped slots 21 of the insulating body 2 and thus contact the shield cross 31.
  • the outwardly pointing tabs 12 of the shielding element protrude beyond the connection area 202 of the insulating body 2 to connect with the one not shown here Contact connector housing 4.
  • the Figures 3a and 3b show the not yet assembled connector in a side view and in a 3D representation.
  • the connector has the said connector housing 4, the shielding element 1, the insulating body 2 and a combined shield cross / contact arrangement 3.
  • the plug-in area 201, the connection area 202 and the step 203 of the insulating body 2 are provided with reference symbols.
  • a positioning pin 25 at the end of the connection area 202 is also designated. This is used to position the insulating body 2 on the circuit board 5.
  • the combined shield cross / contact arrangement 3 comprises the shield cross 31, an attached contact carrier 32 and eight socket contacts 33 held thereon, only four of which are visible in the drawing because the others are optically hidden by the visible socket contacts 33.
  • the socket contacts 33 in this illustration in the contact carrier 32 are shown displaced in relation to their assembly state, counter to the plug-in direction. In the assembled state, they are intended to protrude beyond the cross shield 31 in the plug-in direction and, after they have been inserted into the insulating body 2, to terminate almost flush with the through openings 23.
  • the Figures 4a and 4b show the largely assembled connector with the separate connector housing 4 in a side view and in a 3D illustration.
  • the combined shield cross / contact arrangement 3 is introduced into the insulating body 2.
  • the connector housing 4 is shown floating above the plug-in area 201 of the insulating body 2.
  • the shield element 1 is plugged onto the insulating body 2. Its inwardly pointing tabs 11 engage in the slots 21 of the insulating body 2.
  • the outwardly pointing tabs 12 protrude beyond the connection area 202 of the insulating body 2.
  • the ring 13 is arranged on the step 203.
  • the electrically conductive connector housing 4 When the electrically conductive connector housing 4 is plugged in, it contacts the outwardly facing tabs 12 of the shield element 1 with little force and a relatively large common contact surface To bend connector housing 4 around the connection area 202 of the insulating body 2 and thus on the one hand to reduce the expenditure of force and on the other hand to produce a particularly large common electrically conductive contact surface with the connector housing 4.
  • the inwardly pointing tabs 11 of the shield element 1 also contact the shield cross 31 with a relatively large electrically conductive contact surface and adjoin it.
  • the Figure 5a shows one with the Figure 1c comparable illustration, the printed circuit card 5 being provided here with insulating bodies 2 which have shielding elements 1 according to the invention.
