Definitions

  • the present invention relates generally to antenna grounding and mounting technology, and specifically to the mounting and grounding of an antenna in a mobile device. More particularly, the invention relates to a grounding clip for mounting within an antenna tube to enhance antenna grounding.
  • EP-A-0476848 discloses a socket contact assembly comprising a ring shaped tubular body and a spring clip formed by four inwardly extending tines located within the tubular body.
  • US-A-3383645 discloses a socket contact assembly comprising a ring shaped tubular body and a spring clip formed by a single inwardly extending spring leg located within the tubular body.
  • US-A-5232382 discloses a socket contact assembly comprising a ring shaped tubular body and a spring clip formed by an opposed pair of inwardly extending beams located within the tubular body.
  • JP-06097712 A discloses a radio equipment antenna comprising a coil element set at the tip of a wire element. The rear end of the wire element opposite the tip is grounded via a correction circuit.
  • the invention provides a grounding clip adapted to be installed into an inner end of an antenna tube to enhance antenna grounding, the grounding clip comprising: a base ring resiliently deformable in a radial direction, said base ring having an outer circumference for contact with the antenna tube and a gap in said base ring for compression of said base ring; and at least one resiliently flexible contact pin being affixed to and extending from a first end of said base ring, angled tabs affixed to and extending from said first end and a second end opposite said first end of said base ring, said angled tabs projecting inwardly from the outer circumference of said base ring, wherein each of said at least one contact pin is adapted to contact a contact block of an antenna along a length of each of said at least one contact pin to enhance antenna grounding.
  • the grounding further comprises two resiliently flexible contact pins.
  • the contact pins are affixed along said base ring at an angle of between 90 and 120 degrees.
  • the at least one contact pin has a bend therein, the at least one contact pin extending inwardly from said outer circumference of said base ring between said bend and said base ring, and extending back towards said outer circumference of said base ring after said bend.
  • the at least one contact pin is formed to be integral to said base ring.
  • the at least one contact pin has a forked end on an end of said at least one contact pin opposite said base ring.
  • the at least one contact pin has a tab at an end of said at least one contact pin opposite said base ring, said tab adapted to bear against said antenna tube.
  • the grounding clip is formed through a progressive stamping die.
  • the at least one contact pin is gold plated and is formed of metal.
  • the at least one grounding clip is curved to fit about the antenna base in a contact area.
  • the invention provides a mobile device having an antenna assembly including the grounding clip of the first aspect.
  • the invention provides a method of grounding an antenna, comprising: providing a grounding clip adapted to be installed into an inner end of a tube of the antenna, the grounding clip comprising a base ring resiliently deformable in a radial direction, said base ring having an outer circumference for contact with the antenna tube and a gap in said base ring for compression of said base ring; and at least one resiliently flexible contact pin being affixed to and extending from a first end of said base ring, and angled tabs affixed to and extending from said first end of said base ring and a second end opposite said first end of said base ring, said angled tabs projecting inwardly from the outer circumference of said base ring; the method further comprising arranging each of said at least one contact pin to contact a contact block of an antenna along a length of each of said at least one contact pin to enhance antenna grounding:
  • Figures 1 and 2 show a tube assembly 10 for a retractable antenna 25.
  • Tube assembly 10 includes an outer metal wall 12 that is formed to a precise inner diameter ensuring very little deviation.
  • Tube assembly 10 is mounted to a printed circuit board (PCB) 14 using surface mount technology clips (SMT) 16.
  • SMT clips provide an electrical contact between tube assembly 10 and PCB 14.
  • Antenna 25 includes an external protective sheath 30 at the antenna's outer tip, an antenna shaft 32, and a contact block 34 (seen more clearly in Figure 3 ). Antenna 25 is held at the shaft's upper end to the hand held device using a mount 36. Mount 36 provides some stability for antenna 25 and further provides some weather protection for tube assembly 10 to limit the ingress of water.
  • a user can extend antenna 25 by pulling external sheath 30 outwardly relative to the hand held device. This causes antenna shaft 32 to move through mount 36, pulling antenna contact block 34 with it. Contact block 34 moves from a position near the inner end 18 of tube assembly 10 to a position towards the outer end 20 of tube assembly 10.
  • retraction is performed by pushing external protective sheath 30 towards the hand held device, causing antenna contact block 34 to move towards inner end 18 of tube assembly 10.
  • Grounding clip 40 is best seen in Figures 3 to 15 .
  • Clip 40 consists of at least one, but preferably two resiliently flexible contact pins 42 connected to or formed integrally with a base ring 44.
  • grounding clip 40 is installed into the inner open end 18 of tube assembly 10.
  • Tube assembly 10 is formed with a circumferentially extending groove 46 that is used to hold grounding clip 40 in place.
  • clip 40 can be inserted into tube 10 until base ring 44 snap fits securely into the space between groove 46 and the tube's inwardly curved lip 48 with both the insertion of the clip and, if necessary, its removal, being facilitated by the angled tabs 41 at the inner and outer ends of the base ring 44.
  • the end of tube assembly 10 is preferably formed into a tapered lip 48.
  • Clip 40 is then installed into the space between groove 46 and lip 48 using some elastic deformation of the clip to fit it over lip 48. Preferably, a small jig is used to accomplish this insertion. Grounding clip 40 is thus locked in place between the tapered lip 48 of tube assembly 10 and groove 46.
  • Each contact pin 42 is essentially dog legged in shape which provides for clearance between each pin and groove 46 and allows the longer portion 43 of each pin to taper from the dog leg's apex 52 to tab 50 that is adapted to bear against the tube 10's inner surface.
  • the surface 55 of each pin portion 43 between apex 52 and tab 50 is a flexible contact area for making electrical contact between clip 40 and contact block 34 at the inner end of the antenna's shaft as the antenna is fully or partially retracted.
  • Figure 15 shows that if antenna contact block 34 is located between points 54 and 56 of contact area 55, contact pin 42 makes physical and electrical contact with the antenna contact block 34.
  • Contact pin 42 is preferably gold plated within this area to ensure optimal contact and hence grounding.
  • Grounding clip 40 is preferably formed through a progressive stamping die. This ensures that the clip has very well controlled dimensions for consistent installation within each tube assembly 10. This ensures that pins 42 have very good repeatable positions when compared between one tube assembly 10 and another.
  • the slope between points 54 and 56 is designed to produce an optimal contact area. This is done by ensuring that the contact area 55 is as long as possible, and that contact pin 42 is resiliently flexible. This assembly creates a long contact area 55 that produces more chances for the grounding of antenna 25. Specifically, antenna 25 does not need to be fully retracted into the tube in order to achieve proper grounding.
  • clip 40 includes two contact pins 42.
  • the use of two pins ensures that proper contact is maintained with antenna contact block 34 by providing a three contact grounding.
  • the first two contact points are between block 34 and the two contact areas 55 on contact pins 42.
  • the spring forces produced by contact pins 42 on antenna contact block 34 will force antenna contact block 34 into contact with the inside of tube assembly 10, created a third grounding point as shown most clearly in Figure 15 .
  • the optimal configuration for contact pins 42 will not be diametrically opposed to one another, but rather at an angle of between 90 and 120 degrees from one another.
  • FIG. 16 show alternative configurations for contact pin 42.
  • a contact pin 42 is shown with a forked end 43.
  • Forked end 43 provides sufficient stability to ensure contact pin 42 does not move when antenna contact block 34 is retracted.
  • contact pin 42 can be curved, as illustrated in Figure 17.
  • Figure 17 shows contact pin 42 with a single contact point 55 at one end.
  • contact area 55 is curved to fit around antenna contact block 34, ensuring contact pin 42 is not moved to the side of antenna contact block 34 when antenna 25 is retracted.
  • Tube assembly 10 is mounted to PCB 14 using surface mount technology clips 16.
  • SMT clips 16 are used, and these clips 16 connect to associated clips on PCB 14. Clips 16 will hold tube assembly 10 in the X and Y directions. The combination of two clips will restrict rotation in the X and Y axes.
  • the present invention further includes a radially extending flange 60 at the front or upper end of tube assembly 10.
  • Flange 60 fits into a groove 62 cut into PCB 14. The combination of flange 60 and groove 62 ensures that tube assembly 10 will not move in the tube's axial direction.
  • One advantage of the above mounting technique is that contact performance will be improved. If the tube were allowed to move axially, the retraction point of antenna contact block 34 would vary, thus making accurate grounding more difficult to achieve.
  • the present invention further provides for improved waterproofing by providing a tube 70 within tube assembly 10. Water may enter tube assembly 10 from mount 36 when antenna 25 is retracted. This is overcome by plastic tube 70 and cap 72.
  • Tube 70 is preferably fabricated from plastic and is affixed to mount 36. Tube 70 extends from mount 36 to contact area 55. Preferably, a small gap exists between tube 70 and tube assembly 10 to facilitate insertion of plastic tube 70 into tube assembly 10. Further, even after the housing of the mobile device is closed, plastic tube 70 can be inserted into tube assembly 10 using the opening for mount 36.
  • Cap 72 can be comprised of metal or plastic, and fits snugly on the end of tube assembly 10, thus providing a seal.
  • the present invention is directed at the mounting and grounding of an antenna in a mobile device.
