Abstract

The spring plate (2) is designed as a closed frame for surrounding the plug opening to which spring arms (3) are attached that project outwards towards the housing wall (4). The spring arms form a flexible contact with the housing wall (4). In addition, contact lugs (10) are fitted to the frame which project into the plug opening and position the spring plate and which effect the shield contacting of an inserted mating connector.

Shielded PCB socket with Schirmungskontaktie- tion to a device wall

The invention relates to a shielded printed circuit board receptacle having an insulation body, which is accommodated in a metallic screening housing which is fixed on a circuit board and that has a substantially rectangular cross-section, so that a rec teckförmige plug-in opening is formed, and electric with a frame-shaped spring plate for the plug-side and mechanical connection of the screen housing with a housing wall.

Shielded PCB connectors (Universal Serial Bus) concept has become known in particular in connection with the target of several computer manufacturers standardized USB and interest. In this new bus system is about to make the connections of peripheral devices to a PC not as previously via individual parallel ports with separate and often different connector systems, but substantially serially connect the peripherals to a common bus line principle, which has a standardized socket on the housing of the PC directly to a circuit board (mother- board) of the PC is connected. The mating face of the printed circuit board receptacle (receptacle) is already substantially defined by a specification, and has four in a plane adjacent strip-shaped contact springs, which during insertion of the cable-side bus connector (plug) and cooperating with the disposed in these four adjacent contact bars to the electrical -Establish contact. The adjacent contact springs are in their rear region to terminal areas (down upstanding connecting legs) is angled, which can be inserted in four adjacent contact holes of the printed circuit board.

The metal shielding enclosure is usually soldered firmly over multiple connections to the printed circuit board. In order to meet current EMC (electromagnetic compatibility) guidelines, must in PC's, which are electrically connected mounted on printed circuit boards input / output connector with the housing wall. In addition to the conventional method to verεchrauben the plug under considerable additional installation effort with the case, it is known to compensate for the assembly tolerances between the circuit board with the mounted socket connectors and the device wall by flexible springs. These can be integrated into the housing wall, and in the connector itself. A key criterion for sufficient flexibility in both cases the sheet thickness: The stronger the material, the longer the springs must be carried out, which the least possible with limited installation space and

Material consumption can be problematic. Alternatively, it is also known to connect the normally relatively thick-walled screen plate by means of a screwed additional thin spring plate electrically connected to the housing wall.

The present invention is based on the object, the printed circuit board receptacle of the aforementioned type so further develop that an assembly-friendly and reliable contact resilient connection between the shield case and a overall housing wall is produced. The screen housing may be designed with a mating side formed by outwardly bent tabs insertion aid to be inserted for a mating plug. This object is achieved with a printed circuit board female connector of the aforementioned type characterized in that

- the spring plate as a closed, the insertion opening circumferential frame is formed,

- the frame at least two issued from the frame to the housing wall toward spring arms are connected that contact the flexible housing wall when installed,

- and in that the frame also comprises at least two Kontaktierungslaschen are attached, which are designed to project into the insertion opening inwardly such that the spring plate is positioned circumferentially around the plug-in opening in the plug opening plane and at the same time shielding enclosure of an inserted into the circuit board receptacle Gegensteckerε by these

Kontaktierungslaschen is electrically contacted.

Further developments of the invention are subject of the subclaims.

The invention is described in more detail using an exemplary embodiment erläuter Match a printed circuit board socket in connection with FIGS.

Show it

1 shows a perspective view of

(Exploded view) of a first embodiment of a printed circuit board female connector according to the invention with spring plate, FIG 2 in a slightly different perspective view of the socket shown in FIG l, but with mounted spring plate, FIG 3 is a perspective view of a built in a device printed circuit board connector. In the right part of FIG 1, a shield casing 1 is visible, in which an insulating body is pushed 8 and which is fi xed by means of links 6 in the holes of a printed circuit board. 7 Depending on the arrangement and tolerances of the circuit board 7, a more or less large distance between the plug face of the connector and a housing wall (4) is obtained. In the middle of Figure 1 a spring plate 2 which, cf. be seen. Figure 2, for the front portion (insertion opening) is provided the receptacle. It is designed as a frame and does not cover the actual plug-in opening. For example, four spring arms 3 contact with their free, possibly rounded ends during insertion of the circuit board in the device whose housing wall 4 which has a corresponding recess (5) for insertion of the cable-side mating connector and ground via the shield case 1, the printed circuit board. 7

The positioning of the spring plate 2 within the Stecköff--voltage level, such as a Figure 2 seen in the height alignment by the top and bottom and with respect to the transverse orientation by the left and right Kontaktierungsla- on the frame of the spring plate 2 may advantageously additional specific 10th latching arms 11 be arranged to engage with the mounting behind the lateral Einführlaschen 9 of the screen housing 1 and thus fix-voltage level, the spring plate 2 perpendicularly to Stecköff-. The Kontaktierungslaschen 10 do not extend perpendicular but somewhat obliquely into the plug-in opening.

To give the respect to the shroud relatively thin spring plate 2 sufficient stability, it is designed as a closed frame. When pressed against the housing wall, the whole frame 4verhält not rigid, but flexibel.Die spring arms 3 bend when Aödrücken in the insertion direction and are thereby, depending is how close the circuit board connector on the housing wall, more or less to the housing wall 4 towards aufgespreitzt or widened. funnel-shaped, so that their visible in particular in figure 3 flared arrangement. Although the arrangement of the spring arms 3 in the corner of the frame is associated with increased spring properties, but is by no means mandatory. By bending when pressing the horizontal frame segments 12, cf. bulge. Figure 3, away from the plug-in direction, ie from the horizontal Einführlaschen. 13 In the installed state, thus possibly give circumferentially six contact points of the

Spring plate 2 to the housing wall 4 which have about the same distance from each other, whereby the screening effect is improved.

The advantages of the circuit board receptacle invention consist initially in good spring action, which goes back to the very thin (about 0.1 mm) spring steel sheet and the high flexibility of the selected structural design. In particular, in the illustrated arrangement of the spring arms there is a high contact reliability by four or six points of contact. The inventive solution has an overall relatively low additional space required, it can be inexpensively manufactured with low plate consumption and easy to install. The spring plate can, of course, depending on the customer, if necessary, are simply omitted.

In FIGS 1 and 4 it is seen that the shroud 1 causes four locking hooks 14 a Mindestanziehkraft for mating cable connector. The required sheet thickness loading contributes ca.0,3 mm. For a resilient spring path of the plug-in front of at least 0.5 mm, the previously known design variants are therefore too short or too bulky. A matching cable connector contact when plugged in via the Kontaktierungslaschen 10 directly the housing wall. 4

The printed circuit board connector according to the invention can be used, moreover, at a mating face doppeistöckigem (two plug-in openings).
