Definitions

• the present invention relates to a connector shell for a multiple wire cable assembly having multiple ground conductors and signal conductors.
• a connector shell is used in particular for a multiple signal connector in the telecommunication industry.
• box-shaped coaxial cable termination sockets also known as SCI connectors (shielded controlled impedance connectors) are described in US-A-5, 184,965, DE-C-41 16 168, and DE-C-41 16 166.
• SCI connectors shielded controlled impedance connectors
• a certain disadvantage of coaxial cable termination sockets having a box-shaped design i.e. having a design which is non-coaxial, results in a loss of signal transmission and increase of signal reflection properties of the termination socket for high frequent signals in the MHz range.
• the box-shaped coaxial cable termination sockets basically are satisfactory concerning high density packaging aspects, there are limits concerning the speed and frequency of the signals transmitted through the termination sockets. With higher frequency in the GHz range the attenuation increases.
• the known corrugated sleeves are provided in the coaxial connectors in order to adapt the connector to coaxial cables different in diameter.
• the corrugated sleeves of adjacent coaxial connectors are not interconnected among each other.
• ground bussing strips for connecting the housings of box-like coaxial cable termination sockets.
• An example of such a socket connector is disclosed in US-B-6,171,143 and EP-A-0 952 637.
• This socket connector is adapted to receive multiple coaxial cable termination sockets and includes two opposite longitudinal recesses which are adapted to expose parts of the outer conducting casings of the termination sockets. These exposed parts are contacted by a plurality of metallic fingers of two connecting elements formed as metallic strips.
• the metal plate is provided with large throughholes having terminal connectors with signal contact elements extending therethrough wherein the signal contact elements receive signal pins of the mating connector part when the two connector parts are joined together.
• a further socket connector shell for receiving termination sockets of the cables of a multiple wire cable assembly is known from WO-A-03/012934.
• corrugated elements of an electrically conductive material are arranged as a ground bussing means.
• grounding and, in particular, the grounding paths have to be improved.
• a connector shell for a multiple wire cable assembly having an enhanced electrical performance so as to be suitable for very high-speed transmission of signals.
• the connector shell comprising: a housing having a ground potential, a multitude of contact elements arranged in a longitudinal array, the contact elements being provided for making electrical contact to contact elements of a mating connector and comprising: (i) grounding contact elements for connecting to the ground conductors of the multiple wire cable assembly and (ii) signal contact elements for connecting to the signal conductors of the multiple wire cable assembly, a longitudinal grounding plate extending along and in the longitudinal direction of the array of the contact elements, the grounding plate having two lateral edges at least one of which is provided for electrical connection to the ground potential of the housing, wherein the grounding plate comprises throughholes having the grounding contact elements extending therethrough, and wherein at the throughholes the grounding
• the housing comprising an electrically conductive material such as e.g. metal and by the grounding plate being in electrical contact with the electrically conductive material of the housing.
• all the grounding contact elements of the connector shell according to the invention extend through the grounding plate or through the plane defined by the grounding plate.
• the grounding contact elements are in mechanical and electrical contact with the grounding plate in that the grounding contact elements extend through throughholes of the grounding plate at which the grounding contact elements are electrically connected to the grounding plate.
• the signal contact elements need not to extend through the grounding plate or the plane of the grounding plate. For instance the signal contact elements could bypass the grounding plate or could be extend above and beyond the lateral edges of the grounding plate.
• the grounding plate is made of metal and, accordingly, is designed as a metal plate.
• the grounding plate can be an integral part of the housing or a portion thereof.
• the grounding plate is separated from the housing and can be mounted thereto e.g. by screws.
• an electrical gasket for shielding potential gaps between the grounding plate and the housing.
• the housing has a ground potential. This ground potential can be realized by a conductive layer arranged along the walls of the housing.
• the housing can comprise a wall of a non-conductive material which is coated by a layer of conductive material forming the ground potential.
• EMI electromagnetic interference
• the interior of the housing should be designed as a Faraday cage as basically known to those skilled in the art. In that regard it is most preferred that the housing comprises metal walls.
• the terminal connectors 54 are SCI connectors including one signal contact element and one grounding contact element.
• terminal SCI connectors like e.g. those including two signal contact elements and one common ground contact element can also be used.
• the conductors of the cables 16 can also be directly connected to the contact elements 46 by e.g. wire wrapping.
• the terminal connectors 54 receive the contact elements 46 of the contact element array 44. Due to this arrangement, the signal conductors of the cables 16 are electrically connected to the signal contact elements 42 and the ground conductors of the cables 16 are connected to the ground contact elements 40 of the contact element array 44. As shown in Fig. 3, the terminal connectors 54 are held in place by means of protruding ribs 58 projecting from the inner surfaces of the housing halves 20,22 and being arranged above the housings 56 of the terminal connectors 54 so as to prevent the terminal connectors 54 from inadvertently releasing from the contact elements 46.
• grounding plate 24 is shaped like a frame having a central cut-out portion 60 and two rows of throughholes 62 arranged adjacent the cut-out section 60 at opposite sides thereof and adjacent to the lateral edges 28.
• a cut-out section 60 is dimensioned such that all of the signal contact elements 42 which are arranged within the central portion of the array 44 of contact elements 46 extend through the cut-out section 60 without contacting the grounding plate 24 (see also Fig. 3).
• the individual throughholes 62 of the grounding plate 24 have a size such that the middle portions 50 of the grounding contact elements 40 frictionally engage the grounding plate 24 within the throughholes 62 (see Fig. 4). Accordingly, all the grounding contact elements 40 are grounded to the grounding plate 24 which contacts the inner surfaces of the housing halves 20,22 (see Fig. 3) and, accordingly, is grounded along both its lateral edges 28. However, it is to be noted that for the invention it is merely necessary that one of the lateral edges 28 of the grounding plate 24 is electrically connected to the ground potential of the housing 18 which ground potential in this embodiment is provided by one of the housing halves 20,22. As can be seen from Fig. 2, the grounding paths along the grounding plate 24, i.e.
