Connector provided with a shield plate
The invention relates to a connector comprising an insulating housing module and at least one shielding plate, the housing module comprising a number of signal lines and at least one earth conductor extending between a meeting side and a contact side of the connector and wherein the shielding plate has one or more more comprises fastening elements which make contact with the earth conductor and which each comprise a distal part and an intermediate part which extends between the screening plate and the distal part.
EP-A-1 107 387 discloses a connector comprising an insulating housing, a number of contact elements positioned in rows and columns in the housing and at least one shielding plate arranged between adjacent columns of contact elements. The shielding plate is a structurally separate component provided with fastening means and is attached to only one of the contact elements of a column of contacts by means of the fastening means.
A disadvantage of the prior art is that the fastening means require a considerable amount of space between the earth line and adjacent signal lines. As a result, the distance between the lines cannot be reduced to meet the requirements for high-density cable connectors on the meeting side of the connector.
It is an object of the invention to provide a connector provided with a shielding plate which makes contact with the earth conductor, wherein the distance between the leads can be reduced in comparison with the distance between the leads according to the prior art.
This object is achieved by providing a connector, characterized in that the distal portion has a deformable structure for coupling to the ground conductor. The structure of the fastening elements according to the present invention therefore allows an elastic deformation of the fastening element substantially parallel to the earth conductor. In the state of the art, the intermediate part of the fastening means is deformed so that the opposite tabs can clamp over the sides of the earth conductor. The fastening means therefore exert a contact force on the earth conductor parallel to the plane of the shielding plate, such that these fastening means deform in the direction of the earth conductor to the signal lines. As a result, the connector according to the present invention requires less space between the ground lead and the adjacent signal line than the connector according to the prior art and, therefore, the density of signal leads and ground leads can be increased.
In an embodiment of the invention, at least one distal part of the fastening elements forms part of a press-fit connection with a corresponding part of the earth conductor. A simple and reliable connection of the shielding plate is hereby obtained.
In an embodiment of the invention, the signal lines and the earth line are positioned in a column parallel to the shielding plate and at least one distal part is arranged between the earth line and one of the signal lines. The fastening elements at the state of the art are provided in pairs on both sides of the earth conductor, which results in a larger number of fastening elements.
In an embodiment according to the invention, the at least one distal portion cooperates with the insulating housing module. The insulating housing module provides a suitable connector component for the fasteners provided on one side of the ground lead to assist in developing a contact force on the ground lead.
In an embodiment according to the invention, the earth conductor comprises at least one opening for receiving the distal part. By introducing the fastening element into an opening of the earth line, no space is required between the earth line and the adjacent signal line for receiving the fastening element. The opening is preferably provided at the contact side of the earth conductor.
More preferably, the grounding conductor is wider on the contact side than on the encounter side, since a wider grounding conductor provides a better location for the opening, while near the contact side the distance between the lines can typically be greater than for the encounter side for a high density connector. It is noted that the opening can also be used for fastening elements without a deformable structure at the distal portion.
In an embodiment according to the invention, the screening plate comprises one or more screening flanges which extend from the screening plate and abut against one or more walls of the insulating housing module. These shielding flanges include the insulating housing module in part and, as a result, ensure that the differential impedance of the connector is only determined by the signal lines, the grounding conductor, and the shielding plate of the connector.
In an embodiment according to the invention the distal part comprises two wings. These wings can make an angle with a direction parallel to the earth conductor. When the wings of the securing element make contact with the ground lead, they spread along the ground lead to develop a gradually increasing contact force when the wings elastically deform parallel to the ground lead.
The invention also relates to a connector assembly comprising a number of connectors or connector modules, as described above, and a holder for holding the connectors. Board connectors as provided on printed circuit boards should typically be connected to cable connectors provided with a plurality of leads positioned in rows and columns. The connector assembly according to the invention provides a row of high-density connectors with a reduced distance between the leads at at least the meeting side of the connector.

In an embodiment according to the invention, the insulating housing modules each comprise one or more projecting parts and the holder comprises slots for receiving the projecting parts. In this embodiment the holder is suitable for holding the series of connectors.
It is noted that the embodiments described above, or aspects thereof, can be combined.
The invention will hereinafter be illustrated with reference to the accompanying drawings, which schematically show preferred embodiments according to the invention. It will be appreciated that the invention is not limited in any way by these specific and preferred embodiments.
In the drawings: FIG. 1 a connector system according to an embodiment of the invention;
FIG. 2 a connector assembly according to an embodiment of the invention;
FIG. 3 the connector assembly according to FIG. 2, wherein the holder and a number of connectors according to an embodiment of the invention are separated.
FIGs. 4A-4D show various illustrations of various components of a single connector of the number of connectors as shown in FIG. 3 without a shield plate; FIGs. 5A-5D show various illustrations of the shielding plate for the connector according to Figs. 4A-4D, and
FIGs. 6A-6C show various illustrations of an assembled connector according to an embodiment of the invention.
FIG. 1, a high-density connector system is shown, wherein a cable connector 1 and a board connector assembly 2 provide an electrical connection for wires (not shown) of a cable 3 after components (not shown) on a circuit board 4. The cable connector 1 comprises a molded base part, a molded housing part and a sheet metal housing part as described in WO 2004/057707, which in the present application is incorporated by means of this reference, which can be inserted into the panel 5. The 1027045 Board connector assembly 2 comprises a holder 6 and can be shielded by a shielding housing 7. The shielding housing is described in WO 2004/057709 and is incorporated by reference in the present application.
FIGs. 2 and 3 show the connector assembly 2 of FIG.
I according to an embodiment of the invention. The connector assembly 2 comprises a number of rectangular connectors 10 each provided with signal lines 11 and a ground line 12 positioned in a column and extending between a meeting side M and a contact side C. The signal lines II and ground line 12 on the meeting side are suitable such that contact can be made are made with the cable connector 1. The holder 7 includes slots 13 to hold the connectors 10.
FIGs. 4A-4D show various images of different components of a connector 10 of the number of connectors shown in Figs. 2 and 3.
FIG. 4A shows a number of high-density rectangular conductive lines or terminals which form the signal lines 11 and earth line 12. The distance d1 between the lines on the encounter side M is 1.5 mm between adjacent signal lines 11 and the distance d2 between the earth line 12 and the adjacent signal line 11 is 1.1 mm. At the contact side C, the requirements for the distance between the lines are less strict. Consequently, the earth conductor 12 has a wider portion 14 near the contact side C in which an opening 15 is provided.
FIGs. 4B-4D show various images of the conduit assembly included in an insulating housing module 16, for example an insert molded lead frame assembly (IMLA). In FIG. 4D, the copper alloy pipes 11, 12 are shown visibly for the sake of clarity, although in practice these pipes will almost always not be visible in the plastic housing module 16. The insulating housing module 16 holds the lines 11, 12 in position.
The insulating housing module 16 has an opening 17 which provides access to the space between the earth conductor 12 1027045-6 and an adjacent signal line 11. The insulating housing module further has a recess 18 which provides full access to the opening 15 in the earth conductor 12 near the contact side C. The opening 17 and the recess 18 are preferably positioned such that access to the earth conductor 12 is provided near the meeting side M and the contact side C. The insulating housing module 16 may comprise other openings or recesses. Finally, the insulating housing module 16 comprises protruding parts 19 which are adapted to cooperate with the recesses or slots 13 of the holder 7 as shown in FIG. 3. Consequently, the connectors 10 can be held by the holder 7.
FIGs. 5A-5D show a shielding plate in various positions. The shielding plate 20 has the function of reducing the influence of external noise sources on the quality of the signal. The shielding plate 20 is made of metal and comprises a flat part 21 and shielding flanges 22 extending from the side of the shielding plate 20 away from the flat part 21. The shielding flanges 22 make it possible to check the differential impedance of the connector 10.
The shielding plate 20 further has a first securing element 23 and a second securing element 24 extending in the same direction as the shielding flanges 22. Each of the securing elements 23, 24 comprises a distal part 25 and an intermediate part 26 extending between the plane part 21 and the distal part 25. The distal parts 25 comprise a deformable structure 27. The deformable structure 27 comprises wings 28 and a slit 29 in the embodiment as shown in FIG. 5D. The rear side of the reformable structure 27 which abuts the insulating housing module 16 has a larger area to distribute the forces over a larger area, so that the housing module 16 is not damaged. On the other hand, the side of the deformable structure 27 facing the earth conductor 12 has a small surface area to realize a greater contact pressure per surface unit. Other deformable structures may be the same and fall within the scope of the present invention. It has been found that the openings in the flat portion 21 have a negligible influence on the electromagnetic shielding performance of the connector 10.
FIGs. 6A-6D show the connector 10 provided with a shielding plate 20 attached according to an embodiment of the invention. The fastening elements 23, 24 are respectively inserted into the opening 17 of the insulating housing module 16 and the opening 15 in the earth conductor 12 to couple to a part of the earth conductor 12. During the introduction of these fastening elements the wings 28 of the fastening element spread 23 extends along the upper side of the earth conductor 12 in the direction of the earth conductor 12 as a result of the interaction with the insulating housing module 16 at the opening 17 and forms a press-fit connection. The wings 28 of the fastening element 24 also gradually spread into the opening 15 of the earth conductor 12 to form a press-fit connection. As a result, the shielding plate 20 is reliably and simply attached to the insulating housing module 16 to form a connector 10, while the distance D2 between the wires defined in FIG. 4A is reduced. Because the connection of the shielding plate 20 to the earth conductor 12 is provided at the encounter side M and the contacting side C, respectively, the receding current in the shielding plate 22 is substantially parallel to the current in the signal line 11, which is advantageous for the performance of the connector 10.
The shielding flanges 22 abut the walls of the insulating housing module 16. Consequently, the differential impedance of each connector 10 can be adequately controlled.
For the connector assembly 2 as shown in Figs. 2 and 3, a number of connectors 10 as shown in Figs. 6A-6C positioned side by side to form a matrix of signal lines 11 and ground lines 12 with each column of lines separated by a shielding plate 20.
