Definitions

  • the present invention relates to a miniature surface-mounted coaxial switch or reversing connector, in particular for electrically connecting a transmitter element to an antenna.
  • a switch connector of the type covered by the invention is described in US Patent 5,174,775 and in EP-A-497,704. This switch connector is used in particular for connecting a portable car telephone to the antenna thereof. this. When this phone is used in portable mode outside the car, it is necessary to disconnect the antenna from the car, so that the phone can operate with its own antenna and its own power source.
  • the radio frequency range transmitted by this type of switch connector is between a few MHz and 3 GHz.
  • the purpose of the present invention is to provide a coaxial switch connector having a simple structure, compatible with the requirements of miniaturization, facilitating surface mounting on a printed circuit board, while allowing the transmission of frequencies included in the range below. above.
  • the invention thus relates to a miniature coaxial switch connector in particular for electrically connecting a transmitting element to a pair of antennas, comprising a hollow body from which at least two contact elements protrude and inside which is axially movably mounted a plunger of electrically insulating material carrying an electrical contact element at one of its ends at the end, this plunger being urged by return means towards a first position in which the end contact element projects at one end of the hollow body and an electrical contact is established between the two contact elements, and said plunger being movable against the action of the return means towards a second position in which the end electrical contact element is erased from said end of the hollow body, is in electrical contact with one of the two contact elements and the latter are isolated electrically from each other, characterized in that the two contact elements protruding from the hollow body are constituted by two blades located in a plane and allowing surface mounting on a printed circuit and in that the plunger comprises a printed circuit board having two conductive tracks cooperating electrically with the contact blades in said first and second positions
  • the axial plunger thus simultaneously moves the end contact element intended for example to be connected to a car antenna, between a projecting position and a retracted position, and establishes contact either with one of the contact blades or with the two blades.
  • Such a construction is therefore simple to carry out and to miniaturize so as to be able to mount the connector on a printed circuit board.
  • the parts of the contact blades projecting from the hollow body are located without a plane perpendicular to the axis of the plunger.
  • the switch or inverter connector advantageously comprises an outer casing made of conductive material, for example metal.
  • it comprises a ground blade cut out from said housing, situated in the plane of said projecting parts of the contact blades.
  • This arrangement also facilitates surface mounting.
  • the miniature surface-mounted coaxial switch connector shown in FIG. 1, in particular for electrically connecting a transmitting element to an antenna, comprises a hollow body 1 from which two contact blades 2, 3 projecting allowing surface mounting.
  • a plunger 4 of electrically insulating material carrying at one of its ends an electrical contact element at the end 5.
  • the plunger 4 is urged by return means 6, 6a to a first position (that of FIG. 1) in which the end contact element 5 projects at one end 7 of the hollow body 1 and an electrical contact is established between the two contact blades 2, 3.
  • the plunger 4 is movable (see arrow F in FIG. 1) against the action of the return means 6, 6a towards a second position, in which the electrical contact element at the end 5 is erased from said end 7 of the hollow body 1.
  • the element 5 is in electrical contact with one 2 of the two contact blades 2, 3 and the two blades are electrically isolated from one another.
  • the contact blade 2 is for example connected to the high frequency transmitter of a car portable telephone.
  • the end contact 5 is in this example, intended to be connected with a car antenna.
  • the other contact blade 3 is connected to the antenna belonging to the mobile phone.
  • the parts of the contact blades 2, 3 projecting from the hollow body 1 are situated in a plane perpendicular to the axis (X-X ') of the plunger 4.
  • the switch connector comprises an outer casing 8, 8a, made of conductive material such as metal.
  • This housing 8, 8a comprises a ground blade (not shown) cut out of the housing 8, 8a, situated in the plane of the projecting parts of the contact blades 2, 3.
  • the end contact element 5 protrudes, in said first position, into a cavity 9 formed, at one of the ends of the hollow body 1.
  • This cavity 9 can be made of an electrically insulating material 10 lining the interior of the hollow body 1.
  • the plunger 4 includes a printed circuit board 11 carrying two conductive tracks 12, 13 electrically isolated from each other.
  • One 13 of these conductive tracks is in contact with the ends 2a, 3a of the two contact blades 2, 3, when the plunger 4 is in said first position.
  • the other conductive track 12 is electrically connected to the end contact element 5.
  • This track 12 comprises a portion 12a axially spaced from the first conductive track 13 which can come into contact with the end 2a of one of the of them contact blades, when the plunger 4 is in said second position.
  • the ends of the two contact blades 2, 3 are each provided with two tabs 2a, 2b pinching the two opposite longitudinal edges 11a, 11b, of the printed circuit board 11 and guiding the axial movement of this card.
  • first conductive track 13 extends perpendicular to the longitudinal axis XX ′ of the printed circuit board 11 and from one longitudinal edge 11a to the other 11b thereof.
  • the second conductive track 12 comprises a first part 12b extending axially from the edge 11c of the card adjacent to the end contact element 5 and a second part 12a extending at right angles to the first until to one 11a of the longitudinal edges of the card 11.
  • the edge 11d of the printed circuit board 11 opposite the end contact element 5 carries a rigid element 14 bearing on one end of a leaf return spring 8 or helical 8a, the other end of which bears against the bottom 15a of the housing 8, 8a opposite the end contact element 5.
  • edge 11c of the printed circuit board 11 adjacent to the end contact element 5 carries a block 15 of electrically insulating material engaged in a cylindrical part 8b, 10a of the housing 8, 8a, so as to guide axially moving the printed circuit board 11.
  • the housing 8, 8a has at its end adjacent the end contact element 5, a surface 7a, 10b, forming a stop for the block 15 of insulating material to limit the movement of the printed circuit board. 11 towards said first position.
  • the electrical connection between the end contact element 5 and the conductive track 12 is made by means of a metallic member in the form of a clamp 16.
  • the two versions represented in FIG. 1 are essentially differentiated by the presence, in the case of the left version, of an insulation layer 10 which is absent in the right version. Therefore, in the right version, the contact blades 2, 3 pass through blocks of insulating material 17 mounted in an opening in the housing 8a.
  • the switch connector that has just been described can be used in a car telephone installation, to connect the radio transmitter to an external antenna.
  • the socket of this external antenna includes a coaxial plug, the central contact of which comes into contact with the contact element 5.
  • the contact element 5 projects into the cavity 9 and the ends of the contact blades 2, 3 are in contact with one another, as shown in FIG. 1.
  • the central pin of the latter comes into contact with the contact element 5 and pushes the latter towards the interior of the hollow body 1.
  • the card 11 then moves in the direction of the arrow F and the conductive track 13 becomes free from any contact with the ends 2a, 3a of the blades 2, 3.
  • the conductive track 12 comes into contact with the end 2a of the blade 2, thereby establishing an electrical connection between the latter and the end contact element 5.
  • the switch connector according to the invention has a diameter of around 6 mm. Its protruding blades 2, 3, 4 located in the same plane facilitate its mounting along the axis XX 'of the connector on a printed circuit board.
  • the contact element 5 could be always supplied, that is to say always in electrical connection with the contact blade 2. This result can be obtained by electrically connecting the conductive tracks 12a and 13.
