Definitions

  • the present invention relates to a coaxial electrical connector also performing a switching function.
  • Coaxial connectors are already known which make it possible to switch a power line to another power line when the two elements of the connector are engaged one in the other.
  • Such connectors are in particular used to connect portable devices to their base while switching electronic functions of the portable device with those of the base, such as for example car radiotelephones.
  • the present invention aims to provide a simple and economical coaxial connector which performs a switching function between two power lines while ensuring good radio isolation between them.
  • Such a coaxial electrical connector comprises, on the one hand, a first connector element comprising a central conductor and an external ground conductor separated by an insulator, and on the other hand, a second connector element comprising a central conductor and a conductor ground which surrounds the central conductor while being separated from the latter by an insulator, as well as a third conductor which is in electrical contact with the central conductor when the two connector elements are uncoupled, the first connector element being arranged for , when it is coupled with the second connector element, separate said central conductor and said third conductor from one another.
  • the coaxial electrical connector according to the invention is characterized in that, over most of its length, the third conductor of the second connector element is separated from the central conductor by the ground conductor.
  • the third conductor of the second connector element is arranged outside the coaxial line defined by the central conductor and the ground conductor.
  • the connector according to the invention provides good radioelectric insulation between the two power lines, one comprising the central conductor and the other the third conductor, insofar as the ground conductor separates these two lines on the largest part of the length of the second connector element.
  • the ground conductor of the second connector element comprises two sections of different configurations, namely a rear section of semi-cylindrical shape defining a partition extending from the rear face of the connector element up to the point of contact between the central conductor and the third conductor and surrounding the central conductor, and a front section of cylindrical shape defining a partition extending from said point of contact to the front face of the connector element and surrounding both the central conductor and the third conductor.
  • the rear section of the ground conductor comprises an additional partition which encloses the third conductor in order to protect the electrical signal conveyed, if necessary, by this third conductor.
  • FIG. 1 represents in axial section a connector element 1 comprising a central conductor 2, a ground conductor 3 separated from the central conductor 2 by an insulator 4, and a third conductor 5.
  • the central conductor 2 is terminated at its front end by a female elastic contact 6 intended to receive the male central contact 7 of a complementary connector element 8 which is shown diagrammatically in broken lines in FIG. 1.
  • the insulator 4 extends forward in the form of a sleeve 4 a which surrounds the female elastic contact 6.
  • the ground conductor 3 surrounds the central conductor 2 over the entire length of the connector element.
  • the ground conductor 3 has a rear section T a and a front section T b which have different configurations.
  • the rear section T a of the ground conductor 3, visible in FIG. 3, comprises a lower partition 3 a of circular section and a planar upper partition 3 b , while the front section 3 b of the ground conductor 3 is only constituted by the circular partition 3 a which extends over most of the periphery of the connector element.
  • the third conductor 5 extends parallel to the planar upper partition 3 b of the earth conductor 3 and has a contact tab 9 cut in its width which comes to bear, in the rest position, on the female elastic contact 6 of the central conductor 2, when the two complementary connector elements 1 and 8 are uncoupled.
  • the sleeve 4 a of the insulation 4 includes a light 4 b allowing the passage of the tab 9.
  • the third conductor 5 is trapped in the insulation 4 at its rear part and free at its front part where it comprises a flexible zone 5 a which allows it to deform during the coupling of the two connector elements, its termination in shape spatula 5 b bearing on the chamfered front part 10 of the complementary connector element 8.
  • the contact tab 9 moves away from the central conductor 2 and opens the circuit electrical consisting of the central conductor 2 and the third conductor 5.
  • the spatula-shaped termination 5 b of the third conductor 5 can come into contact with the external ground conductor 11 of the element of additional connector 8.
  • most of the length of the third conductor 5 is separated from the central conductor 2 by the ground conductor 3.
  • the earth conductor 3 'of the connector element 1' has an additional partition 3 ' c which extends the lower partition 3' a and encloses the third conductor 5 , so that the latter is also isolated from the outside.
  • the impedance of each electrical line can be precisely fixed by suitably choosing the dimension of the air gaps 12 and 13 which separate the ground conductor 3.3 ′ from the central conductor 2 and respectively from the third driver 5.
