Definitions

  • the present invention relates generally to electrical connectors and more particularly to a connector device adapted for use in a portable radio communication device, such as a mobile phone. It also relates to an antenna device and a portable radio communication device, such as a mobile phone, comprising such a connector or antenna device.
  • contact pins in the technical field of mobile phones. Such contact pins are used as radio frequency contact means between for example a built in or internal radiating element and a printed circuit board (PCB).
  • PCB printed circuit board
  • An example of such pins is sold under the trademark PoGo, so-called PoGo-pins. Because there are radio frequency applications involved, it is of vital importance that the contact point is well defined, as otherwise the RF characteristics will vary for the radiating element in an unwanted way.
  • German utility patent document DE 198 52 636 Al discloses a connector element with an holding portion and a contact end interconnected by a spring portion. The contact end is adapted for soldering to an object and the entire connector element is unitary. This makes the described connector element unsuited for RF applications. It is also difficult to adapt the described connector to different lengths, making assembly difficult.
  • An object of the present invention is to provide a connector device for use in a portable radio communication device wherein the contact point between the connector and a contacted object is well defined and the connector is adapted for good RF signal transfer.
  • Another object of the present invention is to provide a connector device, which is easy and inexpensive to manufacture and assemble.
  • the invention is based on the realization that the above mentioned objects can be achieved by providing a contact pin with a separate spring element provided at one end portion thereof .
  • the connector device according to the present invention provides a connector device that is easy to manufacture and assemble and that provides a well defined path for RF signals passing between two objects, such as a radiating element and a printed circuit board of a mobile phone.
  • FIG. 1 is a perspective view of a first embodiment of a connector device according to the invention
  • FIG. 2 is an enlarged view of the lower end portion of the connector device shown in FIG. 1;
  • FIGS 3 and 4 are side and front views respectively, of the connector device shown in FIG. 1;
  • FIG. 5 is an exploded view of the connector shown in FIG. 1;
  • FIG. 6 is a perspective view of a second embodiment of a connector device according to the invention.
  • Fig. 7 is an enlarged view of the lower end portion of the connector device shown in FIG. 6;
  • FIGS 8 and 9 are side and front views respectively, of the connector shown in FIG. 6;
  • FIG. 10 is a detailed view of a spring element used with the connector shown in FIG. 6;
  • FIG. 11 is a perspective view of the connector shown in FIG. 1 used with a first embodiment of a connector support;
  • FIG. 12 is detailed view of the support shown in FIG. 11;
  • FIG. 13 is a view of a second embodiment of a connector support before mounting; and FIG. 14 is a detailed view of the support shown in FIG. 13.
  • a connector generally designated 1
  • the pin element is made of an electrically conductive material, such as copper, a copper alloy, or stainless steel, or it can be provided with a plating of a suitable material, such as gold or a suitable corrosion resistant alloy.
  • a suitable material such as gold or a suitable corrosion resistant alloy.
  • the pin element comprises an elongated body 12, the upper end portion 16 of which is adapted to be attached to a radiating antenna element 20 in some suitable way, such as by soldering, riveting or welding or by means of a so-called star-lock arrangement.
  • the radiating element is described as a planar conductive element made of for example sheet metal and having an essentially square or rectangular shape.
  • the radiating element can take many different shapes and the rectangular shape shown in the figures is just a general outline of the shape of the radiating element.
  • the radiating element preferably is made of a sheet metal, also other solutions are viable, such as a plastic support having a conductive flex film attached thereto and functioning as an antenna pattern.
  • the configuration of the pin element 10 enables a mounting to the radiating element which provides for an efficient utilization of the radiating element area, i.e., the attachment area comprising e.g. a rivet does not occupy a large area that could have been used for the radiating element itself as is the case in some prior art solutions.
  • the pin element 10 is provided with a circumferential groove, creating a waist portion 14 close to the lower end portion 18 of the pin element 10, see FIG. 5.
  • the function of this waist portion 14 will be described below.
  • the connector device 1 also comprises a spring clip 30 with a shape generally resembling an "U” turned over 90°.
  • the spring clip thus has an upper leg portion 32 and a lower leg portion 34 with a typical mutual dis- tance "d" of about 1 millimeter, see FIG. 3.
  • the upper leg portion 32 is provided with a cut-out portion 36, see FIG. 5, having a width essentially corresponding to the diameter of the waist portion 14.
  • the cut-out portion 36 is preferably narrower at the outer end thereof, having a width slightly less than the diameter of the waist portion of the pin element, thereby retaining the waist portion in a fixed position.
  • the lower leg portion 34 is provided with a generally circular protrusion 38 at the underside thereof.
  • the protrusion 38 functions as a contact point to an underlying substrate, such as a printed circuit board (PCB) 40 of a mobile phone 50, the general outlines of which are denoted by dashed lines, see FIGS. 3 and 4.
  • PCB 40 printed circuit board
  • the pad typically has an area of 2x2 millimeters, although the size can vary.
  • the protrusion 38 is positioned on the center axis of the pin element 10. This is particularly advantageous as the forces exerted by the connector device are directed in a direction perpendicular to the planes of the antenna element 20 and the PCB 40. This eliminates any radial forces that possibly can change the position of the protrusion on the PCB, thereby altering the RF charac- teristics of the signal path.
  • the protrusion is created e.g. by means of a stamp process, etching, or milling.
  • the protrusion 38 can be provided as part of a gold-plated wire or the like that is welded onto the underside of the lower leg portion 34.
  • the signal path through the spring clip is rela- tively short, which ensures good RF characteristics for the connector device.
  • the provision of a separate spring clip is advantageous when considering manufacturing and storage aspects, as only one type of spring clip has to be manufactured and stored.
  • the pin element 10 is then manufactured in different lengths typically ranging from 4 to 12 millimeters but shorter or longer pin elements are also possible. This modular concept reduces manufacturing costs and also provides a solution wherein less storage space is required.
  • the described connector device can be made very short; to the length of the pin body 12 is only added the distance between the lower end portion 18 of the pin element and the lower leg portion 34 of the spring clip 30, which typically is less than 1 millimeter. This distance varies in a very small degree, ensuring well-defined electrical characteristics of the connector device.
  • FIG. 6 a perspective view of a connector de- vice, generally designated 1'.
  • the connector device 1' comprises a pin element 10 identical to that described with reference to the first embodiment and attached to a radiating antenna element 20.
  • the spring clip 130 of the second embodiment differs from that of the first embodiment.
  • the spring clip 130 comprises an upper portion 132 having a cutout portion 136 corresponding to the cut-out portion 36 of the first embodiment.
  • it is designed to co-operate with the waist portion 14 of the pin element 10.
  • the upper portion 132 of the spring clip 130 extends into two legs 134a, 134b generally forming an angle ⁇ of approximately 45° with the plane of the upper portion, see FIG. 10, and having a respective end portion 135a, 135b being essentially parallel to the upper portion 132.
  • the end portions 135a, 135b are provided with a respective protrusion 138a, 138b corresponding to the protrusion 38 of the first embodiment.
  • the spring clip 138 is thus provided with two well- defined contact points that can be used to establish electrical contact with an underlying substrate, such as a PCB 140, see FIGS. 8 and 9 showing a front and side view, respectively, of the connector device 1 ' connected to a PCB.
  • the two protrusions 138a, 138b contact either a single pad or two different pads (not shown) on the PCB, depending on the application.
  • the symmetrical configuration of the spring clip 130 ensures uniform contact pressure of the two contact points.
  • the pin element 10 has been described as a self-supporting element attached to the radiating element 20. However, it is realized that it is also possible to provide a support structure or a supplementary guiding part, preferably made of plas- tics.
  • a support element generally designated 200, used together with a connector of the kind described with reference to FIGs . 1-5.
  • the connector is attached to an antenna element 20 mounted in an antenna carrier 210, two walls of which 212, 214 are shown in FIG. 11.
  • the antenna carrier 210 is in turn mounted in a telephone chassis, generally designated 220.
  • the support element has a length slightly shorter than that of the pin element 10 and is provided with a through hole 202 with a diameter adapted for receiving the pin element 10.
  • the support element 200 is also provided with a dovetail portion 204 adapted to cooperate with a corresponding slot in the antenna carrier 210. By means of the dovetail arrangement, the support element 200 is firmly attached to the wall 214 of the antenna carrier 210.
  • the pin element 10 is attached to the antenna element 20 in some suitable way, as has already been described above.
  • the support element 200 is then thread onto the pin element. Finally, the spring clip 30 is attached to the pin element 10.
  • the support element is provided in two halves, see FIGs. 13 and 14.
  • two parts 302, 304 together form a support element 300 with a shape as the one shown in FIGs. 11 and 12.
  • the parts 302, 304 are held together by means of a pin and hole arrangement, comprising four pins provided on part 302, three of which pins 306a-c are shown in FIG. 13, arranged to cooperate with corresponding holes 308a-d in the part 304, see FIG. 14.
  • the spring clip 30 can be attached to the pin element 10 before it is mounted in the support element 300.
