Definitions

  • the present invention relates to a female socket connector of the type comprising a centrally located bottom pole and, coaxial thereto, an annular pole which is disposed in an internally cylindrical housing.
  • Connectors of this kind are common in cars, caravans and boats and are being used to connect exterior consumers such as torches, television and radio receivers etc. to a source of current.
  • the most frequent and well known application, however, of connectors of this kind is that of a socket and retainer for a cigarette lighter in passenger cars.
  • One type of such a connector comprises a cylindrical metal sleeve constituting at the same time the connector housing and its annular pole, which, thus, is fed only by direct contact with surrounding portions of the car or the like in which it is mounted.
  • One object of the present invention is to provide a novel connector of the kind indicated which is not necessarily fed by direct contact with the object in which it is mounted but is preferably fed through contact means disposed in the bottom area of the connector.
  • Another object is to provide a connector which comprises simply and inexpensively manufactured parts which are easily assembled by the manufacturer or by the user.
  • the shoulder retaining the annular pole also serves as a retainer for a male connector introduced in the female connector.
  • the connector according to the invention comprises a housing 1, which preferably is of an insulating material, such as plastic, an annular pole 2 of a conductive material, such as brass, a bottom plate 3 of an insulating material and a bottom pole 4 of a conductive material, such as e.g. brass (fig. 1).
  • the cylindrical part Internally, relatively close to the mounting flange 5, the cylindrical part is provided with an annular shoulder 8.
  • axial slots have been provided in order to form four radially resilient protrusions 9, 10, 11 and 12, which are evenly distributed around the periphery of the cylindrical part.
  • the protrusions also extend beyond the bottom plane 13 of the cylindrical part.
  • the protrusions are provided with external bevels 14 and inwardly of these with likewise external locking recesses 15, the defining surfaces of which located closest to the mounting flange 5 are levelling with the bottom plane 13 of the cylindrical part 7.
  • the annular pole 2 is preferably an originally plane sheet metal detail comprising a band-shaped portion 17 bent into an annular shape, the ends of which are inclinedly cut such that they complete each other in the annular shape to form, axially viewed, an overlapping joint 18. From these ends extend equally long support tongues 19 and 20. Between its ends the band-shaped portion is provided with a contact tongue 21 running in the same direction as the support tongues and being longer than the two support tongues 19 and 20. The free end of the contact tongue is inwardly bent back forming a double folded terminal 22 for the annular pole 2. The free, back bent end of the contact tongue 21 is bent radially inwards to form an abutment 23.
  • the band-shaped portion 17 of the annular pole is so dimensioned, that, bent to annular shape according to fig. 1, it allows insertion into the housing 1 to abutment with the shoulder 8 (fig. 2).
  • the support tongues 19 and 20 are of a length that they extend to the bottom plane 13 of the cylindrical part. In this plane is also located the surface of the abutment 23 turned away from the band-shaped portion 17, while its double folded end forming the terminal 22 extends somewhat beyond the ends of the resilient protrusions 9-12.
  • the bottom plate 3 consists of a circular disc of e.g. plastic, the outer diameter of which corresponds to the outer diameter of the cylindrical part 7 and the thickness of which, at least at the periphery, corresponds to the width of the locking recesses 15 of the protrusions 9-12. Adjacent the periphery the bottom plate 3 is provided with four through openings 24, 25, 26 and 27, which are distributed in correspondence with the distribution of the resilient protrusions 9-12.
  • openings 25, 26 and 27 have ring segment shapes substantially corresponding to the cross sections of the resilient protrusions 10, 11 and 12, respectively, so that these protrusions can be introduced through said openings, while the remaining opening 24 radially outwards has an arcuate shape and radially inwards is plane and is dimensioned so that apart from the protrusion 9 also the terminal 22 can be introduced through same.
  • the bottom pole 4 consists of a plate strip bent to an approximate U-shape, the web portion 28 of which is parallel to the bottom plate 3 and located essentially in the center of same, while its two flanges 29 and 30 extend into and are fixed to the bottom plate, at least the flange 30 extending through the bottom plate, forming a terminal 31 for the bottom pole 4.
  • the bottom pole 4 is manufactured of a material substantially twice as thick as the annular pole 2, while the widths are the same.
  • the annular pole 2 is inserted into the housing 1 to abut against the shoulder 8, whereafter the bottom plate 3 with attached (e.g. moulded-in) bottom pole 4 with its opening 24 is passed over the resilient protrusion 9 and the terminal 22 and with the remaining openings 25, 26 and 27 is passed over the protrusions 10, 11 and 12.
  • the bevels 14 make the protrusions spring radially inwards until the bottom plate abuts the bottom plane 13 of the cylindrical part, whereby the protrusions spring back and the bottom plate is snap-like retained by the locking recesses 15.
  • both the annular pole 2 and the bottom pole 4 can be manufactured of sheet metal of the same thickness, in which case the flange 30 of the bottom pole should be double-folded.
  • An advantage of such an arrangement should be on one hand that one does not have to work with more than one plate thickness and on the other hand that the terminal 31 as well as the terminal 22 (fig. 2) would be finished with a rounded end portion, which may facilitate thrusting-on of the terminal contact.
