Definitions

  • the invention refers to electrical connectors for coaxial cables, that is, cables comprising a central conducting wire and a conducting braiding coaxial to the wire and insulated therefrom.
  • Said connectors have a central pin-shaped contact and an outer peripheral cup-shaped contact, both enclosed within a insulating body and provided with connection means for electrical connection to said cable.
  • Said components are used particularly in the car radio field and in the television field. There is a constant search to reduce and automate connector assembling operations. On the other hand, the connector characteristics are set in very precise specifications from which it is not possible to depart.
  • an angular connector comprising: a inner contact element made of pressed bent sheet metal forming a central pin-shaped part and a clinching or seaming part for clinching to a central conductor wire of a coaxial cable; an outer contact element made of punched and bent sheet metal forming an annular part and, connected thereto, a part having arms for fixing to a braiding of a coaxial cable; an inner insulating element disposed between said first and second contact elements, and an outer plastic insulating body which is injection molded on an assembly made of the first and second contacts preassembled on the cable.
  • a connector according to the present invention has been devised as defined in claim 1 and a manufacturing process thereof as defined in claim 10.
  • the new connector comprises: a first "inner contact” component; a second "outer contact” or “peripheral contact” component; a third “body” or “housing” component that provides insulation between the contacts and around the outer contact.
  • the inner contact component is made of punched and bent conductor sheet metal or foil and comprises a contact plug or pin and a connecting part, in electrical continuity with each other, the connecting part comprising a first pair of connecting tongues for connecting to a central wire of a coaxial cable and a second pair of connecting tongues for connecting to an insulating sheath of the coaxial cable.
  • the second component is made of punched and bent conducting sheet metal or foil and comprises a first annular contact part generally in the form of two half-rings or half-cups and a second connecting part in electrical continuity with the first part. If the connector is angular, the first part and the second part are arranged along axes at right angle to each other.
  • the connecting part comprises a first pair of shielding tongues and a second pair of clinching tongues, the latter to clinch the coaxial cable partly on an exposed braiding of the cable and partly on an outer insulation thereof.
  • the third, insulating component is made of pre-molded plastic and is comprised of two half-shells with engaging means for engagement with each other to form a shell.
  • the two half-shells comprise a half-shell extending on the same side as the contact pin and the contact cup, which forms an insulation between the contact pin and the contact cup, and an opposite back or covering half-shell, the half-shells being pivotally joined together.
  • the plastic shell is shaped with a back part having a connected half-cup, and a second part forming an other half-cup and an insulating portion between the contacts, and the two parts are locked together.
  • Subject matter of the invention is also a manufacturing/assembling process for a connector as defined above, which comprises the steps of providing a first or "inner contact” component made of cut and bent conducting sheet metal or foil; providing a second or “outer contact” component made of cut and bent sheet metal or foil; providing a third or molded plastic insulating shell component; providing one end of a coaxial cable cut and stripped so as to expose a part of a central wire and a part of a braiding thereof; assembling said first component on said cable by clinching first tongues of the first component on the central wire of the cable and second tongues of the first component on an insulating sheath of the cable, situated between the central wire and the braiding; assembling said second component on the cable by clinching second tongues of the second component on the braiding of the cable and on part of the outer sheath of the cable; assembling the third component on the first two components thus assembled and fixing together two parts thereof.
  • the new connector and manufacturing/assembly process enable assembling times and the relative costs to be reduced.
  • the new connector is suitable to be assembled completely automatically on usual so-called "cut-strip-clinch" machines.
  • the connector is particularly useful in the field of radio - TV aerials and signal transmission between hi-fi systems.
  • a pin connector having two contacts, a central contact and a peripheral contact is referenced 10 as a whole and is shown assembled on a coaxial cable referenced C.
  • the connector is angular, is referenced 10 and comprises a first central contact component referenced 20, a second peripheral contact component referenced 30, and a third insulating shell component referenced 40.
  • the component 20 comprises a pin-shaped part 22 and a connecting part 23 connected thereto and at right angles thereto.
  • the connecting part 23 comprises first tongues 24-24 and second tongues 25-25.
  • the first tongues 24 have a limited lateral extension and are in an intermediate position with respect to the pin part 22 and the second tongues 25.
  • the second tongues 25 have a greater extension than the first.
  • Both the first tongues and the second tongues are preferably preformed with a shape extending on the same side and the tongues 25 have a slightly curved shape.
  • the curve of one tongue 25 and the other is not specular but one tongue has its end further from the base than the other, to facilitate clinching to cables with different diameters.
  • the element 20 is obtained from flat, cut and bent conducting sheet metal or foil.
  • the cylindrical pin part is bent so as to close along a generating line.
  • a plurality of components 20 are preferably provided as a continuous band and, as illustrated in Figure 4, joined to a sheet metal ribbon F, which can be seen in said figure, through a narrow neck F'. Once the neck F' has been broken, each component 20 can easily be bent into the position in Figure 6.
  • the fact of providing the component as a continuous ribbon is particularly useful for automatic assembling.
  • the second component 30 can be seen clearly in Figures 8 to 11.
  • Figure 8 shows a plan view thereof in cut and bent form, but as a continuous band, in which a plurality of components 30 are connected to each other by means of narrow necks.
  • Each component 30 comprises a base part 31 from which two tabs 32 and 32 extend from diametrically opposite sides, said tabs being folded upwards, in Figure 9, and bent in an arc of a circle, so as to define a cup part with diametrically opposite openings.
  • the base part has a circular opening at the bottom defined by an edge 33.
  • the base part extends axially on one side and forms a first pair of tongues 34-34 and a second pair of tongues 36-36.
  • the tongues 34-34 extend upwards substantially parallel to each other and an opening 35 is provided in the base portion therebetween.
  • the tongues 34, 34 have a shielding function in the assembled connector.
  • the tongues 36-36 are bent one toward the other with a nonsymmetrical curvature, as previously explained with respect to the tongues 25 of the first component, to facilitate clamping to cables of different diameters.
  • the tabs 32 bent into a cup in the usual manner, have a narrowing 32' near the edge.
  • the shell component 40 comprises two half-shells 42, 44 pivotally integral to each other along line 45.
  • the half-shell 42 comprises a cup-shaped part 46 able to be disposed around the cup part of the second contact component and a body part 48 integral therewith.
  • the bottom part 47 of the cup part has a through opening 51.
  • the bottom 47 comprises an annular part provided to insulate the first contact from the second contact.
  • the half-shell 42 comprises a plurality of peripheral teeth referenced 52, having an arrow-like shape in sectional view or a per se known shape suitable for coupling.
  • the half-shell 44 comprises a base 54 from which insulating support portions extend, i.e. a first central support portion 56 and a second support portion 58.
  • the half-shell 44 has teeth engagement openings referenced 62.
  • C 1 can also be soldered or electrically spot welded to the tongues 24.
  • the second component 30 is positioned around an intermediate product consisting of the cable plus the first component, and fixed thereto disposing the cup part or tabs 32 around the pin part 22 and spaced therefrom, the tongues 34 at the sides of the tongues 25 and the tongues 36 wrapped and closed (clinched) so as to grip the braiding C 3 and the sheath C 4 .
  • the shell component 40 is applied to the semifinished product in Figure 14c, disposing the cup part 46 around the cup part 32 and the body part 48 to cover the parts 34 and 36.
  • the base 44 is then folded around the pivot line until the teeth 52 and the opening 62 are engaged with each other.
  • the insulating spacing part 56 is disposed through the hole 33 of the component 30 and the insulating spacing part 58 is disposed through the hole 35 of the component 30, and both cooperate to support the first component 20 in the correct position with respect to the second component and insulated therefrom.
  • Figures 15a and 15d a clinching (also said clamping or crimping) process particularly useful for clinching the tongues 25-25 or 36-36, but not limited to use therewith, is described. Said process will now be explained for clinching tongues 25-25 which solely for said figure are called 25f, the one situated on the left, and 25d, the one situated on the right. Clinching dies are referenced 70 for the bottom die and 72 for the top die.
  • Reference C denotes a cable on which the tongues 25, 25 must be clinched.
  • the bottom die is of a traditional type with a cavity 70' of a shape corresponding to the joining part of the tongues that must be clinched.
  • the tongue 25s has a curved end 25's at a slightly lower level than a curved end 25'd of the right-hand tongue; obviously a specular arrangement can also be provided.
  • the upper fixture 72 has a particular cavity 73 with an asymmetrical configuration with respect to a axis a shown vertical through the center of the cable C (dotted and dashed line in the figures), and to be precise the shape comprises a sloping portion 73s on the left and a sloping portion 73d on the right in the figure, forming roughly equal angles with respect to the axis a , but whereof the portion 73s is nearer to the axis a than is the corresponding portion 73d on the right in the figure.
  • the cavity 73 ends in a part shaped like an arc of a circle 73c which comes into operation in the step corresponding to Figure 15d, to press down the tongues one on top of the other around the cable C.
  • a third shell component according to a variant of the invention is illustrated.
  • the shell component is denoted as a whole with reference numeral 140 and is comprised of a half-shell 142 and a half-shell 144.
