Description

The invention relates to a connector with integrated Shielding, for electrical contacting preferably multi-core cable with each other or with a printed circuit board or like. Preferably, the connector consists of a Knife and a corresponding spring strip, the detachable can be connected to each other.

From the going back to the applicant DE 100 51 819 A1 is a connector with shielding known in the both the knife and the spring strip with Shielding are provided. With these shielding is achieved that the electrical connection of the knives and springs each against electromagnetic interference from the outside is shielded as well as the crosstalk from an electrical Contact on the other is prevented. At this Plug connection are the individual contacts of the multipolar Blade and spring strips in several mutually parallel Arranged rows.

For the transmission of electrical signals or a Supply voltage, it is often necessary two or more electrical contacts of the connector pair or group together and with a shield to provide. For this purpose, the respective shielding plates are on Blade and spring strips designed such that they at least two electrical connections, preferably in the form of knife and pen, in pairs or groups in the essentially continuously encircling and outward shield.

With such a connector, however, the orientation the two elements of the connector to each other specified. Due to the design of the shielding is a pairwise shielding two adjacent Contact elements in a row are given only if the both elements in the correct position to each other or, for example. two male connectors from two sides onto a printed circuit board, Board or the like are plugged.

Often, however, it is desired that the two Connector elements from two sides at 90 ° angle, relative to each other, are plugged onto a circuit board. With the known connectors is characterized by a continuous, at least pairwise shielding two contact elements not possible.

Starting from the prior art, the skilled person is the Task set to make a connector such that the two connector elements at 90 ° to each other offset, seen relative to their respective longitudinal extent, connectable to each other or from two sides on one PCB are pluggable, and the pairs or groups Shielding of the contact elements is given; optionally, the Connectors compatible with standardized components.

According to the invention this object is achieved by a Plug connection with shielding with the characteristics of Patent claim 1 solved; advantageous developments and refinements of the invention are the subject matter of claims 2 to 11.

A central idea of the invention is that the in arranged a plurality of mutually parallel rows Contact elements, that is each knife or springs, the respective connector element offset from each other are arranged. This means that at least two of the several rows of contact elements to each other on the gap or mutually offset in the connector element are arranged. In a projection perpendicular to the The longitudinal direction of each row are therefore the Contact elements of at least two of the rows not directly one above the other. Furthermore, the shielding plates are such designed that at least two contact elements, each made one row at a time, in pairs or groups essentially shielded are covered. The shield can while two contact elements of two adjacent rows or several contact elements of several adjacent rows rewrite. Preferably, the contact elements are each shielded in pairs. The respective shielding of the Knife and spring strips are designed such that in plugged state of the connector or when he from two sides on a printed circuit board is plugged, the Shielding around the two or more contact elements is continuously circulating.

With the staggered arrangement of the rows of Contact elements as well as the cross-array shielding it is possible that the two connector elements for Example offset at 90 ° to each other, in their respective Seen longitudinal extension, are connected to each other. The Contact elements have, seen in plan view, a preferably square arrangement to each other, so that the Connector also seen over its longitudinal extent, to each different positions are connected to each other. Due to the arrangement of the shielding is still a continuous shielding to the outside or against Interference from the outside of at least two contact elements given.

In principle, it can be connected to a connector or to a a circuit board plugged connector several more, 90 ° twisted connector can be arranged.

Preferably, the plurality of rows of contact elements are in the respective connector elements arranged such that two groups of rows are formed. The first one in each case Group and the second group is arranged such that in a projection perpendicular to its longitudinal extent the individual contact elements lie on each other. The first and second group of rows, however, is offset from each other arranged.

With an even number of rows, especially four, is a symmetrical design of the Plug connection possible, so that at the connection two plug-in elements in a 90 ° angle all together Contact elements of the multiple rows connectable are.

In an advantageous embodiment of the invention, the respective shielding plates are arranged at 45 ° to the longitudinal extent of the rows of contact elements. They encompass at least two contact elements of two adjacent rows. This also ensures that all contact elements of several rows in pairs or groups are circumscribed by shielding.
In a further development of the invention, the shielding plates are substantially U-shaped. With suitable dimensioning of the shielding plate and the distances of the rows or the individual contact elements to each other is achieved with the nesting of the two connector elements, that the respective legs of the adjacent U-shaped shielding plate together with the back of the first shielding a substantially continuous circumferential shielding of at least form two contact elements.

A further advantageous embodiment of the invention, according to which also the two connector elements offset at 90 ° to each other, seen relative to their respective longitudinal extent, connected to each other or from two sides can be plugged onto a circuit board, is that by a cranking of the contact elements , That is, the electrically conductive pins, on the one hand the arrangement of the contact elements in straight rows, each aligned, and compatible with conventional connectors is possible, on the other hand, with the crank of the contact elements, ie with a substantially z-shaped configuration of the metallic pins achieved in that the outward-facing or protruding third sections of the contact elements, viewed in the longitudinal direction of the contact elements, are arranged offset relative to the first sections of the contact elements arranged in parallel, mutually aligned rows. Thus, these third sections, seen in the axial longitudinal extent of the contact elements, laterally offset from the first sections.
The offset, which is determined inter alia by the size or length of the second portion, which extends substantially perpendicular to the longitudinal extent of the contact element, is preferably selected according to the standardized connector systems.
With the staggered arrangement, seen in the longitudinal direction of the contact element, the third sections to the first sections, it is possible that the respective staggered third sections of two identically formed male connectors, as already mentioned above, from two sides on an apertured board can be plugged so that the respective third sections contact approximately in the center plane of the board and so an electrical connection between the contact elements of the male connectors is made. The inner wall of the openings may themselves be designed to be electrically conductive, so that the tolerances in the production of the contact elements themselves as for the insertion of the contact elements in the said board need not be kept so tight, which has a cost-reducing effect.

After an advantageous development of this variant of Invention is the alignment of the three sections of Contact elements such that the first and third sections, in each case in their longitudinal extent, parallel to each other are aligned and the second sections that the actual Forming bend, are aligned vertically. In special, cost-saving way are such cranked contact elements from known straight contact elements or metallic pins by two preferably simultaneously running bending operations can be produced.

In an advantageous manner, the shielding plates are here also designed essentially as a U-shaped component, wherein the two parallel legs of the "U" are each of the same or different lengths. In particular, two first sections of two contact elements, which are arranged side by side, in parallel rows, jointly embraced by the U-shaped shielding.
For this purpose, it is advantageous that an even number of rows of contact elements is present, so that in each case two adjacent contact elements are provided with a common shielding plate. Preferably, four rows of contact elements are arranged in the blade or spring strip.

The knife or spring strips are preferably made of plastic, preferably by injection molding, wherein the respective contact elements are either releasably applicable and can be fixed via a latching connection or are already cast during manufacture.
The shielding plates are obtained, for example, by bending over a flat sheet or cutting to length a sheet-metal profile and are likewise either releasably insertable or already encapsulated in the connector element.

The U-shaped shielding plates, in the form of bent or Angled metal sheets, can also be the bottom of a Pass through male connector, leaving it on the other side survive over the surface of the soil. This can for example, in the manufacture of a male connector Plastic during an injection molding process automatically respectively.

To place the male connectors in the correct position on a circuit board and in particular the bending of the other Variant offset to avoid third sections are further, outward over the bottom surface of the male connector projecting guide elements provided. These are preferably integrally formed on the male connector, are ie e.g. formed during injection molding.

Which faces the respective other connector element Rear of a component is either designed such that another knife or spring strip with the element is connectable or that a multi-core cable directly with the Element is connected.
