EP3695467B1 - Printed circuit board connector having a shielding element and method of assembly - Google Patents

Description

The invention is based on a printed circuit card connector with a shield element according to the preamble of independent claim 1.

Furthermore, 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.

State of the art

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. There are several electrically conductive contacts in an associated contact carrier. These are shielded by means of a shielding plate provided in the contact carrier, the shielding plate making contact with the flange designed as a shielding housing. Based on this, 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. For the transmission of several independent, differential signals, electrical contacts are arranged in pairs in the connector.

In order to attenuate the crosstalk between the signal pairs, 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.

It is also disclosed that 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. On the other hand, 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.

In practice, however, it has been shown that 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 use of such a spring ring, however, has the disadvantage that a groove is required on the round body for this too. This can be made somewhat narrower than in the case of the aforementioned spiral spring design and does not have to run completely around the insulating body. It has also been shown that in this embodiment, too, the force when plugging the connector housing is not optimally implemented because the spring washer also gets into a certain inclined position and possibly tilted instead of, as desired, only dodging inwards in order to establish electrical contact with the screen cross. Its effective contact area is also rather small with respect to both the housing and the screen cross at the corresponding contact points, which has a negative effect on the electrical conductance of this screen connection.

The German Patent and Trademark Office researched the following prior art in the priority application for the present application: U.S. 5,029,908 A , U.S. 4,938,714 A and US 2006/0125235 A1 .

Task

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.

This object is achieved by the features of the independent claims.

• Einen Isolierkörper mit einem im wesentlichen zylindrischen Steckbereich, welcher durch mehrere in Steckrichtung verlaufende Schlitze in vier Segmente unterteilt ist, wobei jedes der Segmente mindestens eine Durchgangsöffnung zum Einfügen je eines elektrischen Buchsenkontaktes besitzt, wobei der Isolierkörper an den Steckbereich anschließend einen ebenfalls im wesentlichen zylindrischen Anschlussbereich aufweist, wobei der Anschlussbereich einen größeren Durchmesser besitzt als der Steckbereich, wodurch zwischen dem Steckbereich und dem Anschlussbereich eine umlaufende Stufe gebildet ist;
• mehrere in den Durchgangsöffnungen angeordnete Buchsenkontakte, die durch den Anschlussbereich des Isolierkörpers verlaufen, um mit Anschlüssen der Leiterkarte elektrisch zu kontaktieren,
• ein in dem Isolierkörper aufgenommenes Schirmkreuz,
• ein elektrisch leitfähiges Steckverbindergehäuse, sowie
• das besagte Schirmelement zur Kontaktierung des Steckverbindergehäuses mit dem Schirmkreuz, wobei das Schirmelement zumindest teilweise aus einem elektrisch leitfähigen Material gebildet ist,

• wobei das Schirmelement einen geschlossenen Ring aufweist, an den sowohl nach innen als auch nach außen weisende federelastische Laschen angeformt sind,
• wobei das Schirmelement mit seinem Ring auf der umlaufenden Stufe des Isolierkörpers angeordnet ist, mit seinen nach innen weisenden Laschen in die Schlitze hineingreift, um einerseits das Schirmkreuz elektrisch zu kontaktieren, und mit seinen nach außen weisenden Laschen über den Anschlussbereich hinausragt und/oder um den Anschlussbereich herumgebogen ist, um andererseits das Steckverbindergehäuse elektrisch zu kontaktieren.

A circuit card connector has at least the following:

• An insulating body with an essentially cylindrical plug-in area, which is divided into four segments by several slots running in the plug-in direction, each of the segments having at least one through opening for inserting an electrical socket contact, the insulating body adjoining the plug-in area with a likewise essentially cylindrical connection area wherein the connection area has a larger diameter than the plug-in area, whereby a circumferential step is formed between the plug-in area and the connection area;
• several arranged in the through openings Socket contacts that run through the connection area of the insulator in order to make electrical contact with connections on the printed circuit board,
• a screen cross accommodated in the insulating body,
• an electrically conductive connector housing, and
• said shield element for contacting the connector housing with the shield cross, wherein the shield element is at least partially formed from an electrically conductive material,

• wherein the screen element has a closed ring on which both inwardly and outwardly pointing resilient tabs are formed,
• The shield element is arranged with its ring on the circumferential step of the insulating body, with its inwardly pointing tabs reaching into the slots in order to make electrical contact with the shield cross on the one hand, and with its outwardly pointing tabs protruding over the connection area and / or around the Connection area is bent around, on the other hand, to electrically contact the connector housing.

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. In other words, 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.

Advantageous refinements of the invention are specified in the subclaims.

In an advantageous embodiment, 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. On the one hand, this is very useful because of the given shape of the cross shield and the insulating body. On the other hand, such a multiple ground connection is particularly advantageous for high-frequency applications.

In further preferred embodiments, 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.

In a preferred embodiment, 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.

It also has a particularly advantageous effect on the conductivity, in particular for the said derivation of electrical signals of high frequencies, if the entire screen element is formed from an electrically conductive material.

In a particularly preferred embodiment, the shield element is formed from a sheet metal lying in the plane of the ring, preferably punched out of it. In particular, the shield element can be a stamped and bent part. The sheet metal is advantageously electrically conductive. In particular, the sheet metal has elastic properties.

Such a PCB connector can be made as follows:

• Introducing the cross shield and the socket contacts into the insulating body and fastening the cross shield and the socket contacts in the insulating body;
• Fastening the insulating body with the cross shield on / on the circuit card and electrically conductive connection of the cross shield with at least one ground connection of the circuit card as well as electrical contacting of the socket contacts inserted in the insulating body at corresponding connections of the circuit card,
• plugging the shield element onto the insulating body and arranging the ring of the shield element on the step between the plug-in area and the connection area;
• Contacting the shield cross with the inwardly facing tabs of the shield element by engaging them in the slots of the insulating body;
• Attaching the electrically conductive connector housing to the insulating body and establishing an electrically damaged connection between the connector housing and the shield cross by electrically contacting the connector housing with the outwardly facing tabs of the shield element.

The term "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.

This assembly process is particularly easy to carry out. In particular, 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. Finally, it often happens that a printed circuit board with several connectors is built into a device housing. In particular, 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.

In another embodiment, 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. In addition, the manual effort is relatively large.

By minimizing the individual forces that arise when each individual connector housing is plugged onto the individual insulating body, the overall assembly force is ultimately reduced accordingly, which means that assembly is simplified. In addition, the circuit board is protected from correspondingly high mechanical stresses during the assembly process.

Furthermore, 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. Conversely, 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 figures contain partially simplified, schematic representations. In some cases, identical reference symbols are used for identical, but possibly not identical elements. Different views of the same elements could be scaled differently.

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'. At the same time, 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. At the same time, there is a certain amount of play between the printed circuit board 5 and the housing wall 6 to compensate for tolerances.

It is easy to imagine that, with this prior art, a considerable amount of force is required in order to simultaneously plug the multiplicity of connector housings 4 onto the insulating bodies 2 'via the associated spring washers 7. Finally, one or more of the spring washers 7 can twist slightly in the plug-in direction and thereby tilt. In addition, the electrically effective contact area between the respective connector housing 4 and the associated spring ring 7 and the electrically effective contact area between the spring ring 7 and the cross shield 31 are only very small. As a result, the ground connection between the connector housings 4 / the housing wall 6 on the one hand and the cross shield 31 / the printed circuit board 5 on the other hand is not optimal.

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.

The 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. For this purpose, 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.

In this illustration, 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. For the sake of clarity, 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.

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.

On the basis of the preceding illustration, it is clear that the printed circuit card 5 now attaches itself to the common ground connection with a significantly reduced expenditure of force and a significantly improved conductivity the housing wall 6 can be attached, the insulating body 2 dipping into the connector housing 4, as shown in FIG Figure 5b is shown.

Even if various aspects or features of the invention are each shown in combination in the figures, it is clear to the person skilled in the art - unless stated otherwise - that the combinations shown and discussed are not the only possible ones. In particular, corresponding units or feature complexes from different exemplary embodiments can be exchanged with one another.
