Definitions

  • the invention relates to electrical connectors, in particular electrical connectors for high frequencies.
  • the present invention provides a solution to this problem of industrial production of connectors with easily adaptable capacitive filtering, under satisfactory technical and economic conditions.
  • the proposed electrical connector device is of the type comprising a first part, male or female, consisting of a metallic body of generally cylindrical shape, which houses a contact-carrying insulating block radially, with individual contact elements firmly held inside. of the insulating block, these contact elements having one end, male or female, on the side where the second part of the connector comes, female or male respectively, and this metal body receiving, opposite the second part of the connector with respect to the first, an additional conductive ring, while at least one capacitive paver with multi-layer ceramic dielectric is provided, with axial metallized perforations according to the same geometry as the contact elements, this device also comprising a ground connection comprising the connector body.
  • Such a device is for example described by FR-A-2 297 503.
  • the invention also relates to the new industrial product constituted by a removable casing with capacitive filtering, for an electrical connection device comprising a metal body which accommodates radially an insulating block carrying contact capable of receiving contact elements, this casing being characterized in what he understands:
  • a support washer is provided between the capacitive block and the insulating block; and the pins each have a shoulder engaging exactly in a respective perforation of said support washer, which allows precise positioning of the pins without excessive stress on the capacitive pad.
  • the female sockets consist of an axial cutting of the contact elements defining at least one axial clamp in the shape of a lyre, on which is externally crimped a cylindrical collar open at its free end with a lip capable of guiding the introduction of the pin into the lyre-shaped clip.
  • a conductive washer forming a radial spring, curved with concavity towards the outside, and ensuring the ground connection between the peripheral metallization of the block and the conductive ring as well as the body. connector.
  • the connecting pins are of square cross section, and there is provided, on the other side of the capacitive pad, another washer pierced in the format of the cross section of the pins, which avoids mechanical stress excessive pavement during the installation of the conductive wires, in particular by winding.
  • the additional ring houses adjacent two capacitive blocks, the homologous metallized perforations of which are crossed by the same pins with interposition between the two blocks of means forming an inductance on at least some of the pins, which allows you to define filters in 7t.
  • the additional ring comprises on the side of the pins a wavy radial washer forming an axial spring, and urging the capacitive block (s) in abutment on the contact-holder insulating block.
  • the ring is mounted axially linked and free to rotate on a threaded nut able to mesh on a homologous thread from the rear of the connector.
  • this male connector part is illustrated, the female part, not shown, being well known to those skilled in the art.
  • this male connector part is constituted as a base, that is to say as the part of the connector which is intended to be fixed on a frame , generally designated by 1.
  • the male part of the connector consists of a metal body of generally cylindrical shape, designated by 10.
  • This body houses radially an insulating contact carrier block, designated by 12, with contact elements, designated by 11, which are firmly held inside the insulating block, in a known manner.
  • These contact elements 11 have an end which here male, but could alternatively be female, on the side where the second part of the connector comes, which is then female or male respectively.
  • Figure 2 shows in more detail one of these male contact elements.
  • the shoulder 111 comes to bear on the block 12, in order to achieve the firm maintenance of the contacts already mentioned.
  • claw-shaped members are provided on the cylindrical part 112, capable of completely immobilizing the contact element inside the insulating block 12.
  • FIG. 2 illustrates in more detail a preferred embodiment of this arrangement.
  • the central part of the contact element 11 is perforated internally, while being cut all around axially, so as to define at least one axial clamp in the shape of a lyre.
  • Figure 2 we see in Figure 2 at 113 and 114 two elements of such a lyre-shaped clamp.
  • Another clamp is here produced in a plane perpendicular to the figure, and we see one of these elements 115.
  • this part which forms the lyre clamp there is externally crimped a cylindrical collar 116, open at its free end, with a lip 117 oriented radially inwards, so as to be able to guide the introduction of a pin into the lyre-shaped clamp.
  • 118 is carried out the crimping of this collar 116 on the internal part which forms a clamp.
  • This embodiment is advantageous in that it allows excellent contact, while leaving a certain freedom of radial play to the spindle which will come to engage in the lyre.
  • the guide of the spindle is indeed achieved by the lips 117, which can advantageously be bevelled towards the opening orifice of the lyre, to further facilitate the introduction of the pins.
  • an additional conductive ring generally designated by 20, and forming housing housing for at least one capacitive block, generally designated by 22, and having a multi-layer ceramic dielectric structure.
  • this block 22 has axial metallized perforations, such as 222, which are produced according to the same geometry as those of the contact elements in the connector.
  • FIG. 3 also shows that these axial perforations such as 222 are connected to first capacitor plates 221.
  • Second capacitor plates such as 223 are connected to a peripheral metallization 224 of the capacitor block 22.
  • An alternating superposition of such plates provides the Capacitive structure with a well known, multilayer ceramic dielectric. Details on the realization of such a structure can be obtained in the French patent application already cited.
  • connecting pins generally designated by 24, pass through the axial metallized perforations of the capacitive block 22, while being welded to these perforations.
  • These connecting pins have one end 240 which will engage the female sockets already mentioned, with lyre-shaped pliers, such as 113 and 114.
  • the pins in question define connecting pins for the conducting wires which will arrive in bundle on the male part of the connector.
  • these connecting pins are of square cross section, to allow the fixing of wires by "wrapping" winding.
  • a support washer 231 is provided between the capacitive pad 22 and the insulating block 12. Is this support washer also perforated according to the geometry of the contact elements. And the pins such as 24 each have a shoulder 241 engaging exactly in a respective perforation of the support washer 231. This arrangement makes it possible to pre-weld the capacitive pad on all of the pins 24, the shoulder 241 coming into contact with one of the faces of the capacitive pad. The washer 231 is then put in place, which will make it possible to ensure excellent radial retention of the pins in position.
  • the additional ring 20 which forms the housing for the capacitive block has internally a flat peripheral recess, in which is housed a conductive washer 250 forming a radial spring, which comes to press on the peripheral metallization 224 of the capacitive block.
  • the washer 250 is preferably made curved with its concavity facing outwards. This produces the ground connection between the peripheral metallization 224 of the block and the conductive ring 20, as well as the connector body as a whole.
  • one of the contact elements of the connector will also be connected to ground.
  • the corresponding perforation in the capacitive block will then be connected directly to the frames 223, without having its own frames such as 221 ( Figure 3).
  • the additional ring 20 has an inwardly facing radial shoulder 201, which serves to hold a radial washer forming an axial spring.
  • This corrugated washer designated by 260, urges the capacitive block 22 in abutment on the contact carrier insulating block. If necessary, the residual opening on the rear face of the ring 20 is closed by a suitable supply of a sealing resin.
  • the entire assembly contained inside the additional ring 20 is mounted separately, at the level of the manufacturer of the multi-layer dielectric capacitive pad, this assembly comprising the ring 20 itself, and all that is between the internal support washer 231, and the spring washer 260 with the possible sealing resin.
  • a threaded nut 30 On the ring 20 is mounted a threaded nut 30.
  • the nut is mounted axially connected to the ring, by a peripheral ring 31 forming a shoulder, while remaining free to rotate relative to said ring.
  • the nut 30 has a threaded portion 32 capable of meshing with the homologous thread 103 from the rear of the connector.
  • FIG. 4 illustrates a second embodiment of the invention, in which a capacitive filtering in ⁇ is provided for the connector pins, instead of the simple capacitive filtering of FIG. 1.
  • FIG. 4 shows a flange 104 with a seal 105 on one side of the wall of fixing 1, while on the other is provided a nut 102 engaging on the thread 101 of the connector. This details the positioning of the base on the frame 1, and may also be applicable in FIG. 1.
  • FIG. 4 The rest of the modifications appearing in FIG. 4 concern the interior of the ring. additional 20.
  • a first washer 231 followed by the capacitive block 22, the external metallization of which is in contact via the domed spring 250 with the conductive ring 20.
  • the capacitive block 22 is here followed to the right a ferrite element 270, associated with a holding member 233, which defines around the pin 242 an inductance, in a manner known to those skilled in the art.
  • This assembly is followed by a second capacitive block 28, generally arranged like the first, but with a possibly different capacity value. Again, internal metallizations to the perforations are welded to the pins 242, while the peripheral metallization of the block 28 is connected by a washer 255 similar to the washer 250 to the external conductive ring 20.
  • the washer 232 provided with perforations with a square cross section, to exactly accommodate the square cross section of the pins 242.
  • the spring 260 ensures the axial pressurization of the assembly, so that the pins 240 enter well inside the female sockets of the contact elements.
