Definitions

  • the present invention relates to a connector system with a male and a female connector devices.
  • Each of those devices has a housing. Said housings are joinable with each other and provided with locking means for releasably locking the male housing against the female housing or vice versa.
  • the male connector device has male connector elements.
  • the female connector device has female connector elements which will effect electrical contact as both connector devices are coupled.
  • Ethernet connector systems have a female connector device which is usually attached to a housing of a component, such as e.g. a computer, and a male connector housing which is usually connected to a cable.
  • the male connector device in the meaning of the present invention is the part of the connector system being inserted into an opening of the female connector device when mating the two housings.
  • the female connector elements are arranged on one side of a rectangular opening to make contact with the male contact elements arranged next to each other in a single plane opposite to the female contact elements.
  • the female contact device has a locking slot which cooperates with a resilient latch provided by the male housing.
  • the present invention specifies a connector system with the features of claim 1.
  • contact surfaces of each connector device are arranged parallel to a contact axis.
  • the contact surfaces of the male or the female connector device are provided by the female or the male contact elements, respectively.
  • a single contact element provides a single contact surface which may define one or more points of contact with the mating contact surface of the other of the male and the female contact devices.
  • the contact axis extends transverse to the mating direction in which the connector devices are moved when being mated or joined for effecting mechanical and electrical contact between the male and the female connector device.
  • respective contact surfaces when being connected with each other, i.e. in the mated or locked stage of the connector devices are sealingly received between the male and the female housing.
  • the sealing is such, that dirt, moisture and water can usually not reach the contact surfaces and thus negatively affect the electrical contact between the male and the female connector device.
  • Sealing is usually attained by means of a compressible sealing element which is compressed in the locked stage of the two connector devices. This compressible sealing element is usually compressed between the male and the female housing to hermetically seal the contact surfaces in the locked stage of the two housings.

  • Provision of the contact surface along the contact axis is advantageous in comparison to a regular M8 or M12-connector having a plurality of contact pins projecting from an insulated surface of the male housing mating with assigned sleeves provided by the female housing. Provision of multiple of those contact pins within a rather limited space will be costly and troublesome.

  • the two connector devices can be connected in a mating direction perpendicular to the extension of the contact axis with each other and still provide the required electrical functionality irrespective of whether the male connector device is inserted into the female connector device in a first orientation or a second orientation which is 180° rotated about an axis which is parallel to the axis of insertion.
  • those locking means are adapted to allow locking of the female housing against the male housing in at least two different orientations.

  • the shielding can shield data from data or data from power.
  • the circular longitudinal element shall be manufactured from an electrically conductive material, in particular metal. Shielding is already attained by the existence of such circular longitudinal element without the need to contact this circular longitudinal element to a shielding of a cable.

  • Four differential pairs (S 1 ⁇ / S 2 ⁇ / S 3 ⁇ / S 4 ⁇ ) are provided.
  • the embodiment may be utilized as a media dependent interface for four copper data.
  • Fig. 5D is essentially identical with that shown in Fig. 5C .
  • a VDD/GND pair is provided as a central pair.
  • the respective embodiment may be used as a media dependent interface for four copper pairs for data and one pair for power supply.
  • a ground plane 150 is provided along the contact axis, i.e. in the middle of the PCB 118 in thickness direction thereof.
  • This ground plane 150 is provided by a conductive layer within the PCB 118 assigned to ground.
  • the ground plane 150 may be use for shielding one side of the PCB relative to the other and/or for connecting ground through the connector system to the female connector device which will then be equipped with an assigned central ground connector.
  • Figs. 5F through H have the same functionality as the embodiments of Fig. 5C, 5D and 5E , respectively.
  • a male connector element assigned to ground GND is provided on both sides relative to CA.
  • all differential data pairs are arranged on the PCB 118 sandwiched between ground contact elements.
  • Figs. 5A and E the neutral positions of VDD and SGN on the bottom, i.e. lower side depicted in Figs. 5E and H , may change. Also, one or more VDD may be changed into additional SGN.
  • the examples of Figs. 5E and 5H represent a media independent interface for an active plug with copper, fiber optics or polymer millimeter wave guide.
  • Figs. 5C through H cope with the problem of providing eight data pins on a smaller space, which data pins are required for high speed ethernet.
  • the embodiments of Fig. 5C through H may not be suitable for being inserted in two different orientations relative to an axis of insertion. Instead, means for properly aligning the contacts relative to each other to safeguard for proper positioning can be provided as e.g. exemplified in Figs. 6 through 13 .
  • the solutions presented in Figs. 5C through H provide for a high number of contacts in a rather narrow space.
  • the threaded sleeve 104 may, for example, be provided with an M8 thread which has a rather small diameter.
  • Figs. 6 through 11 female contact elements (jacks) are exemplified in Figs. 6 , 8, 10 , while the assigned male contact elements (plugs) are exemplified in Figs. 7, 9, 11 , respectively.
  • the circular male longitudinal element 110 is provided with a nub 152
  • the circular female longitudinal element 214 provides a guiding groove 232 adapted to receive the nub 152 for proper alignment of both, the male and the female contact devices 100, 200.
  • the width of the PCB 118 and the assigned slot 130 is such that the slot 230 has lateral surfaces provided by the distal female housing member 206.
  • the slot 230 is a closed slot.
  • the PCB 118 is wider and contacts the inner circumference of the circular male longitudinal element 110.
  • the slot 230 is an open slot not having the lateral walls provided by the distal female housing member 206. Instead, and as the male and the female connector devices 100, 200 are joined and coupled, the slot 230 is enclosed by the circular male longitudinal element 110.
  • Figs. 10 and 11 will allow for additional ground by the circular male longitudinal element 110, which improves signal integrity performance.
  • the number of contacts will not necessarily be increased.
  • the examples of Figs. 5C through E will show the same performance as those of Figs. 11 through H with lateral ground on the PCB 118.
  • the number of contact surfaces in the female housing does not necessarily have to be increased. Connecting the contact pads on the lateral ends of the PCT 118 to the circular longitudinal shield will result in an additional improvement for signal integrity.
  • Figs. 12 through 13 exemplify further embodiments, wherein the embodiment of Figs. 12 and 13 is identical.
  • traditional pin contacts as in a regular M8 through M12 connector are provided, which male traditional pins are identified with reference numeral 154.
  • Those male contact pins 154 may be used for power supply, i.e. VDD and GND or VDD and VSS.
  • those additional male contact pins 154 are provided both on the same side of the PCB.
  • they are arranged on opposite sides of the PCB 118.
