Definitions

  • the present invention relates to connectors comprising a housing at least one contact element provided with a first contact portion for mating contact to another contact element of another connector and a pcb contact portion for contacting a pcb or the like, the connector being divided into at least a main-receptacle unit and a tail-unit, the main receptacle-unit comprising at least one adapting unit provided with an adapting contact member connected to said first contact portion and to a second contact portion and the tail-unit comprising at least one tail contact element connected to said pcb contact portion and to a third contact portion, said third contact portion being arranged for mating contact with said second contact portion.
  • Such connection are known from DE-C-3 904 461.
  • the connector By separating the connector into a main-receptacle-unit and a tail-unit, which are connectable and disconnectable from one another the possibility of converting a connector from straight to right-angle configurations, or changing from through-mount to press-fit connection to a pcb can be provided. Moreover, the difficulty of forming right-angle bending of connector row structures of terminals, can be avoided.
  • a connector comprising a main-receptacle unit 1 and a tail-unit 2 are shown.
  • the main-receptacle unit 1 comprises openings 4 within a housing 3 for accommodating a contact portion 5 of a contact element.
  • the contact portion 5 is integrally made with a tail-conductor portion 6 and a pcb (printed circuit board) contact portion 7.
  • Each contact portion 5 is shown to be of a female-type preloaded with a pre-load rib 10.
  • the housing 3 is provided with a guiding member 9 to facilitate the insertion of another mating connector (not shown) to the main-receptacle unit 1.
  • a fixing pin 8 is provided on the housing 3 for cooperation with a suitable opening in a printed circuit board (not shown) to which the right-angle connector is to be connected. It is to be understand that the phrase "printed circuit board" is used in a very broad sense and incorporates any substrate to which the connector is to be connected and which is provided with suitable conducting tracks.
  • the pcb contact portions 7 are shown to be suitable for through-mounting to a pcb, however, they can be provided in a form suitable for surface mounting, press-fit mounting or IDC.
  • the tail-unit 2 is provided with suitable openings for receiving each of the tail-conductor portions 6.
  • Each of the tail-conductor portions 6 need be individually bent after insertion in the tail-unit 2 and be collected and held together by a separate press-block or waver.
  • clock-speed lower than 1 nanosecond an increase in the cross-talk and reflection of signals result to deteriorate the signal integrity.
  • This is partially due to the relatively long (and varying) tail length and also to the absence of adequate electrical shielding between adjacent tail-conductor portions 6 arranged in rows and columns.
  • the bending of individual rows of tail-conductor portions 6 is difficult and often results in reduced productivity.
  • a coaxial connector module provided with shield members to shield adjacent tail-conductor portions in a right-angle configuration is, e.g., described in European patent application 0,488,482 of the present applicant.
  • this prior art connector separate shield members made of thin, suitably folded metallic plates are provided which are inserted into the housing of the tail-unit.
  • EP-0.562.691-A1 shows an adapting unit connected to a coaxial cable, the outer conductor of said coaxial cable contacting the shielding of said adapting unit.
  • the object of the present invention is to provide such a connector in which shielding of each of the tail-conductor portions can also easily be provided at low costs.
  • the or each tail contact element is made of semi-rigid cable comprising an inner conductor integrally made with said third contact portion and said pcb contact portion, and an outer conductor for shielding said inner conductor and for mating contact with a shielding on a mating adapting unit.
  • Semi-rigid cables are available from many manufacturers and need no special adaptations to be used in the tail-unit of the present invention. They can be easily bent a predetermined angle without deteriorating the impedance. Therefore, they are very suitable for preventing cross-talk and reflection of signals within the connector. No separate shielding plates with which impedance requirements cannot easily be met are required.
  • Figure 2a shows a connector according to the invention which is divided into a separate main-receptacle unit 1 and a tail-unit 2.
  • the same reference numbers in figure 2a refer to the same parts and elements of the connector shown in figure 1.
  • the main-receptacle unit 1 comprises separate adapting units 24 inserted into suitable openings 23 in the housing 3.
  • Each of the adapting units 24 is, preferably, provided with a suitable shielding layer 31 at its outer surface for shielding an adapting contact member 15 provided within the housing 25 of the adapting unit 24.
  • a metallic layer 31 on housing 25 a metal cylindrical sleeve 31, into which housing 25 is to be inserted, can be provided, as shown in figure 2b.
  • each of the adapting contact members 15 is integrally made with a first contact portion 21 and a second contact portion 22.
  • first and the second contact portions 21, 22 are shown to be of a female-type.
  • the present invention is not restricted to such a type of contact portion.
  • a male-type or hermaphrodite type of contact portion may be provided instead, as is known to any person skilled in the art.
  • the tail-unit 2 comprises several tail contact elements 19, preferably made of semi-rigid cables.
  • Semi-rigid cables are known to persons skilled in the art.
  • Each of the semi-rigid cables 19 is provided with an inner conductor 16 integrally made with a third contact portion 20 for suitable contact with a second contact portion 22, and a pcb contact portion 17.
  • the pcb contact portion 17 is suitable for through-mount connection to a printed circuit board or the like. However, a surface mount connection or IDC may be provided instead.
  • Each of the inner conductors 16 is surrounded by an outer conductor 18 for shielding the inner conductor 16.
  • Each of the adapting units 24 is designed to have an extending portion 26 to be received by the end of an outer conductor 18 of a mating rigid cable 19.
  • Any third contact portion 20 is, in use, inserted into a second contact portion 22.
  • Any of the third contact portions 20 may be reinforced by soldering to a suitable contact pin to be inserted into the mating second contact portion 22.
  • the third contact portions may be soldered to suitable female-type contact portions (not shown) when the second contact portions 22 are male-type (not shown).
  • the semi-rigid cables 19 are grouped together within a single housing which need no separate channels for accommodating separate tail conductors.
  • the manufacturing tolerances of a tail-unit provided with semi-rigid cables 19 are relatively large. No ideal bending is required to meet impedance requirements or to avoid deteriorating reflections.
  • Figure 2b shows a front view of an adapting unit 24.
  • the shielding 31 is provided as a cylindrical sleeve.
  • the other reference numbers have already been explained when describing figure 2a.
  • the invention is not restricted to the application of semi-rigid cables within a tail-unit as described above.
  • mini coax-cables can be used instead of semi-rigid cables in a tail-unit 2.
