Definitions

  • the present invention relates to a connector element electric coaxial also performing a switching function, in for switching an electrical line to another line electric.
  • a connector element according to the preamble of claim 1 is known from EP-A-0 154 199.
  • Other connector elements with function of switching are known from US-A-2,640,118 and DE-A-2,707,250.
  • the invention also relates to a connector comprising a such connector element.
  • Known connectors making it possible to provide a switching have two cooperating connector elements, which are each provided with a central conductor and a ground conductor outside.
  • One of the connector elements further comprises a blade flexible metal, which rests on the central conductor at the uncoupled state of the two connector elements, and which is spaced apart by a bearing surface of the other connector element when the two connector elements are coupled.
  • the flexible blade must have a length minimum to be able to bend elastically, which limits the possibility of reducing the size of the connector and allowing the realization of miniature connectors with switching function.
  • the deformations of the blade can, at the long, cause it to lose its elasticity and create reliability of electrical contacts.
  • the blade by resting on the other element of connector when coupling the two elements of connector, undergoes wear which can weaken it.
  • the blade may be damaged or distorted either by a part which would be inadvertently introduced in the connector element by its front face, that is, more simply, by another unsuitable connector element which would be coupled with the connector element comprising the blade.
  • the present invention aims to provide an element of coaxial electrical connector for switching reliably and sustainably and whose structure allows it to miniaturize without difficulty, in particular to be able to mount it on a printed circuit board.
  • the subject of the present invention is a connector element electric coaxial comprising a coupling face with an element of additional electrical connector and comprising a conductor fixed central, a fixed contact piece, a conductive piece axially movable around the fixed central conductor, between a first position in which it leans against the driver fixed central on the one hand, and the fixed contact part on the other hand, and a second position in which it is moved away from the workpiece fixed contact, and a return member capable of bringing the part back conductive axially movable in its first position when the connector element is not coupled to a connector element complementary, characterized in that the conductive part axially movable is a socket which has a front part accessible from the coupling face of the connector element and a rear part which leans against the fixed contact part when said socket is in its first position.
  • the complementary connector element is supported directly against the moving conductive part and pushes it back into its second position, while ensuring the electrical contacting of the central conductors of the two connector elements.
  • the coaxial electrical connector element according to the invention has good reliability due in particular to the fact that it comprises, as the only moving part, the conductive sleeve which slides around its central conductor, but which is supported without friction against the complementary connector element.
  • this socket conductive maybe very weak, which allows to achieve a very small connector.
  • the conductive sleeve is not likely to be damaged or deformed because it can be easily performed under a robust shape with no grip from outside the connector element in which it is housed.
  • the connector element has a ground plate between the part contact and the central conductor.
  • This ground plate which preferably extends over a large axial length, avoids any coupling electromagnetic which could be established between the contact part and the central conductor when the two connector elements are mated.
  • the present invention also relates to a connector coaxial electric consisting of a connector element such as described above and a complementary connector element.
  • the complementary connector element comprises an insulating body intermediate which is located in front of its driver central, so as to push back the movable sleeve and move it away from the contact piece before the two central conductors come into contact electric contact.
  • an electrical connector miniature coaxial which has a connector element intended to be mounted on a printed circuit board (not shown), of the type female 1, and a complementary connector element of male type 2.
  • the female element 1 comprises an external conductive housing 3 cylindrical in shape, which in this case has a diameter external of the order of four millimeters.
  • the upper part in relation to the drawing, of the housing conductor 3 constitutes the coupling face F of the element of connector 1 with the complementary connector element 2.
  • a first cylindrical insulating body 4 closed, on the side of the face coupling F, by a wall 5 which has an orifice 6 centered on the axis of the connector element 1.
  • a second cylindrical insulating body 7 is housed inside of the first insulating body 4. This second insulating body 7 is closed at its lower part by a wall 8 which is also provided with an orifice 9 coaxial to the driver housing 3.
  • the second insulating body 7 also has a slot 12 in which a ground plate 13 engages.
  • a fixed central conductor 14 which extends from the base of the element of connector and protrudes beyond the top wall 5 of the first insulating body 4, through its orifice 6.
  • a conductive sleeve 15, freely fitted around the central conductor 14, has a rear part in the form of flange 16 which is inside the insulating body 4 and a front part 17 which is located outside the insulating body 4, and is therefore accessible from outside the connector element, by the coupling face of the latter.
  • the socket 15 is provided for slide with a small radial clearance around the central conductor 14.
  • the external diameter of the sleeve 15 is slightly smaller than the internal diameter of the orifice 6.
  • This spring 18 works only in compression and does not undergoes no wear by friction when using the connector.
  • the conductive sleeve 15 only rests on the rigid blade 10 in a peripheral part limited of its flange 16.
  • the complementary connector element 2 comprises a housing external conductor 20, an intermediate insulating body 21 and a central conductor 22.
  • the central conductor 22 of the male element 2 is located slightly set back from the front of the insulating body intermediate 21, so that, as seen in FIG. 2, the intermediate insulating body 21 pushes back the conductive sleeve 15 in based on its front part 17 which is accessible from the face coupling F of the connector element and spreads said socket of the rigid blade 10 before making the electrical contact between the central conductor 14 of the female element 1 and the central conductor 22 of the male element 1.
  • the travel of the conductive sleeve 15 is very small, taking into account the dimensions of the connector, but sufficient for perform the switching.
  • the intermediate insulating body 21, which is cylindrical, rests on the entire periphery of the sleeve conductive 15, so that the latter is returned to the axis of the central conductor 14 during its movement, hence very low friction between the guide portion 17 of the sleeve 15 and the central conductor 14.
