Definitions

  • the invention relates to an RF coaxial connector for transmitting high-frequency electromagnetic waves with a housing, with at least one internal contact and with an external contact arranged coaxially around the internal contact.
  • HF coaxial connectors usually have a housing made of a solid material, which receives the respective connection contacts and holds them securely in position.
  • the housings for RF coaxial connectors are therefore usually made of solid metal as a sheet metal part or more often as a cast part made of metal injection molding.
  • metallic housings are not always advantageous to handle due to their weight. In addition, their production is complex and expensive. Finally, it should not be overlooked that metallic housings are relatively heavy, which can also be disadvantageous if weight aspects are relevant when using the plug connector.
  • the housing is formed as an injection molded part made of plastic, and that the housing has a wall section made of plastic and arranged coaxially around the inner contact, in which at least the inner wall facing the inner contact is provided with a sufficiently thick metallization layer .
  • the RF coaxial connector is of multi-pole design with a plurality of pairs of internal contacts and external contacts, the housing being a monoblock with a plurality of hollow cylindrical recesses, each forming a coaxial wall section, in each of which an internal contact sits centrally.
  • the at least the inner walls of all the recesses are provided with a metallization layer.
  • the layer thickness of the metallic layer is determined in accordance with the lowest frequency that occurs as planned, so that the layer thickness at a frequency of 50 MHz, for example, is at least 20 ⁇ m, but preferably 30 ⁇ m.
  • the minimum layer thickness is determined on the basis of the penetration depth of the alternating field that occurs. In this way it can be taken into account that depending on the frequency and the size of the applied alternating field, a different penetration depth results. With increasing frequency, the conductor current shifts more and more against a thin surface layer, the so-called skin effect, so that the current density increases there.
  • silver is preferably provided for the formation of the metallic layer as the layer material.
  • copper or, in special cases, gold can also be provided according to an alternative embodiment.
  • the layer material that is to say the metallization material
  • the metallic layer can either be arranged only on the inner surface or additionally on the outer housing surface of the housing.
  • a thickness of the metallization layer for HF frequencies greater than 50 MHz of 20 to 30 ⁇ m is easily sufficient.
  • Figure 2 shows a straight coupling part of a connector according to the invention.
  • FIG. 3 shows an angled plug part of a connector according to the invention
  • FIG. 5 shows a plug part of a multiple plug connector according to the invention
  • FIG. 6 shows a coupling part of a multiple connector according to the invention.
  • FIG. 1 shows a straight plug part 1 which, together with a straight coupling part 2 shown in FIG. 2, forms a straight plug connector 3.
  • This straight connector 3 is designed as a two-pole, electrically conductive RF coaxial connector.
  • the plug part 1 has a pin-like inner contact 4, which is surrounded coaxially spaced by a metallic sleeve 8a.
  • the sleeve 8a is connected to a cylindrical housing 8 of the plug part 1. Opposite the metallic sleeve 8a is not closer to this housing
  • the coaxial cable shown can be used or has already been used.
  • the housing 8, which is made of non-metallic material is provided with a sufficiently thick metallization layer 30 at least on its inner wall.
  • This metallization layer 30 ensures an electrical connection between the metallic sleeve 8a and the outer conductor of the coaxial cable inserted into the housing, provided that the latter is stripped accordingly.
  • the metallization layer 30 is thus a component of the entire external contact 5 of the plug part 1.
  • the pin-like internal contact 4 is held within the housing in a manner known per se.
  • a sleeve made of non-conductive material, such as plastic can also be provided.
  • the sleeve must be provided with a metallization layer on its inner wall or on the inner and outer wall, so that the required outer conductor function is also guaranteed.
  • the coupling part 2 of the connector 3 has a preferably resilient inner contact 6 in the form of a sleeve consisting of electrically conductive material, into which the inner contact 4 of the plug part 1 can be inserted.
  • the outer diameter of the preferably resilient sleeve is so large that good electrical contact between the two internal contacts 4, 6 is ensured.
  • the inner contact 6 is coaxially surrounded by a hollow cylindrical wall section of the housing 9 of the coupling part 2.
  • the housing 9 consists of
  • REPLACEMENT BLA ⁇ (RULE 26) non-conductive material, such as plastic, which enables significant weight savings compared to metallic housings.
  • a metallization layer 30 which preferably but not necessarily consists of silver or copper with a silver coating. The metallization layer 30 thus simultaneously forms the external contact 7 of the coupling part 2.
  • each housing 8, 9 is formed from an extrudable plastic, at least the mentioned wall sections of the housing 8 or 9 being provided with a metallization layer 30 which serves as an outer conductor or external contact.
  • This external contact 7 is to be electrically connected to the shielding, metallic sheathing of a cable, in particular a coaxial cable.
  • the inner contact 6 of the coupling part 2 is to be connected to the inner conductor of such a coaxial cable. The same applies to connector part 1.
  • the metallization layer can be arranged not only on the inner wall of the housing 8 or 9 but also on the outer wall.
  • FIG. 3 shows a further plug part 10 which is angular in comparison with the plug part 1 according to FIG. 1. Together with an angular coupling part 11 shown in FIG. 4, it forms a further plug connector 12, which is used for the angular connection of coaxial conductors (not shown in more detail).
  • the connector 12 is also provided with a housing 13 for the plug part 10 and with a housing 14 for the coupling part 11, the housing 14 again having a metallization layer 30 on its hollow cylindrical wall which coaxially surrounds the internal contact 6 is provided.
  • the multi-pole connector 60 consists of several straight-line coaxial connectors 41, which are combined into a unit 55 by means of a common mounting plate 42 on a base e.g. a printed circuit board 43 or a rear wall and by means of press-in contacts at a certain pitch of e.g. 5 mm are attached.
  • the connector 60 also consists of a base, e.g. on a circuit board 45 or an assembly arranged coaxial mating connectors 46, which are integrated in a number corresponding to the number of coaxial connectors 41 and at the same pitch as these in a monoblock 47.
  • This consists of non-conductive material and is provided with a metallization layer 30 at least on its hollow cylindrical inner walls which coaxially surround the inner contacts 48.
  • These eight metallization layers 30 form the different outer conductors for the eight coaxial mating connectors 41 integrated in it, their pin-like inner contacts 48 (FIG. 7) with their connections being insulated by bores 51 and 50 made of insulating material in bores 51 and perpendicular to them. th holes 52 of the monoblock 47 are added. It follows from this that the coaxial mating connectors 46 are designed in an embodiment angled by 90 ° to their direction of insertion.
  • connections of the internal contacts 48 of the coaxial mating connectors 46 and the external contact connections are press-in contacts 53 or 54 formed, which are arranged according to the 90 ° angle of the coaxial mating connector at an angle of 90 ° to the direction of insertion.
  • 5 and 6 show that in the illustrated embodiment of the RF coaxial connector 60 according to the invention two superimposed rows of coaxial connectors and accordingly two superimposed rows of coaxial mating connectors, each with four coaxial connectors 41 and four coaxial mating connectors 46 are provided, so that the coaxial connectors 41 form an 8-way unit 55 and the monoblock 47 is designed as an 8-way mating connector.
  • the monoblock 47 has eight press-in contacts 53 for the inner conductor connections and 5 ⁇ 3 press-in contacts 54 for the outer conductor connections.
  • the press-in contacts 54 are connected to the metallization layer 30, which is applied to all inner walls of the housing of the monoblock 47, in an electrically conductive manner.
  • the press-in contacts 54 have projecting wall sections 72 which lie flat against the metallization layer 30.
