Definitions

  • An adaptable male connection device corresponding to the preamble of claim 1 to different cigarette lighter socket diameters is known from the patent GB2293054A.
  • This device consists of an internal sleeve and an outer sleeve.
  • the outer sleeve is provided with at least one holding lug that may move laterally away from a initial position by a spacer device, when one of the sleeves slide relative to each other in a relative motion longitudinal. This spacing then causes the increase of outer diameter of the male connection device up reach the correct diameter to maintain the device in the cigarette lighter plug.
  • Adaptation of the connection device male to the diameter of the cigarette lighter socket therefore results from a longitudinal sliding movement of a sleeve of said device compared to the other, this movement being an extension of the insertion and extraction movements of said device.
  • This male connection device has at least one major disadvantage. Indeed, at each insertion / extraction of said device, the spacing of the retaining lug is likely to be modified. Therefore, the adaptation of the diameter of the male connection device to the diameter of the socket must be performed at each new connection.
  • An object of the present invention is to remedy in a large measure to this disadvantage and to provide a device for male connection for connecting an electrical appliance or electronic to a female socket, in particular of the cigarette lighter type, reliably, so that the diameter of said device can be adapted in advance to the diameter of the socket.
  • This rotary spacing device has the advantage of being adjustable in advance to the diameter of the socket to avoid the user to make this adjustment at each new connection.
  • a device for blocking the rotary spacing device to block rotation of a sleeve relative to each other is provided.
  • Another object of the present invention is to provide a male connection device less sensitive to potential misalignments caused by multiple insertions / extractions. Indeed, the adaptation of the diameter of the male connection device according to the invention requiring a relative rotational movement between the inner sleeve and the outer sleeve of said device, the probability that the gauge will go wrong during an action insertion (or extraction) of said device, into (or from) the socket is very small, these actions insertion / extraction during movements longitudinal not requiring rotation.
  • FIG. 1 represents an exploded perspective view of the male connection device according to one embodiment preferred embodiment of the invention.
  • Figure 2 shows a perspective view of the male connection device according to the preferred embodiment of the invention.
  • Figure 3 shows in A, B, C and D four views of male connection device according to the preferred embodiment of the invention.
  • Figure 4 shows these same views for a value different of female socket diameter.
  • FIG. 5 represents an exploded perspective view of a variant of the preferred embodiment according to the invention.
  • Figure 6 shows an exploded perspective view another variant of the preferred embodiment according to the invention.
  • the device according to the preferred embodiment shown in FIG. 1 comprises an internal sleeve 10, a sleeve 12 surrounding the inner sleeve 10, at least one leg of holding 14 disposed outside the outer sleeve 12, the tab holding member 14 may be conductive.
  • a rotary device 16, secured to the inner sleeve 10, allows to spread radially the holding tab 14 of an initial position, when of a relative rotational movement between the inner sleeves 10 and 12.
  • the rotary spacing device 16 comprises a cam member 18 having a cam profile, so that the holding lug 14, secured to the outer sleeve 12, deviates from its initial position under the action of the cam member 18 to adapt the external diameter of the connection device male to the inner diameter of the socket 17 and hold them in mechanical and electrical contact after insertion.
  • the end of male connector device has an element electrically conductor 19 intended to cooperate with a conductive element of the socket to ensure a first electrical contact.
  • a second electrical contact is made on the side walls male and female parts of the connection device. For that, it is provided a metal device 21 elastically pressed towards the outside of the inner sleeve 10 by a return spring 15 and sliding through openings in said sleeve 10.
  • a printed circuit board 11 provides the interface between the first and second contacts described above and the electrical circuits of the device that you wish to connect to the socket. 17 the embodiment chosen, the spacing of the holding tab 14 under the action of the cam 18 can be obtained by different means. If the natural elasticity of the material does not allow to obtain the desired spacing, we can provide a means of recall elastic (not shown).
  • FIG. 3 the view shown in A represents a section along the plane [C-C] of the view represented in B.
  • the view shown in D represents a section along the plane [B-B] of the view represented in B.
  • the view shown at C represents a section according to the plane [D-D] of the view represented in D.
  • a blocking device 13 consisting of a first set of teeth on the periphery outside of the inner sleeve 10 and a second series of teeth on the inner periphery of the outer sleeve 12 is shown in C in FIGS. 3 and 4.
  • This locking device with detent locks 13 allows to maintain the spacing of the tab 14.
  • An enlargement detail of locking notches 13 allows to understand how the sleeves 10 and 12 cooperate during the rotation of the cam 18.
  • FIG. 4 represents the same views as FIG. 3, the sleeves 10 and 12 having rotated at an angle ⁇ to one with respect to the other. So we see in Figure 4 how the leg 14 is raised under the action of the cam 18 to vary the diameter of the male connection
  • FIG. embodiment according to the invention in which the holding lug 14 is arranged longitudinally on the outer sleeve 12.
  • the device according to another embodiment shown in Figure 6 shows the same elements as the one shown in Figure 5, with the difference that the roles of the outer sleeves 20 and 22 are reversed with respect to FIG. device includes an additional element, a means of recall elastic strap (not shown) for holding the tab 24 in a initial position forming an angle with the axis of the inner sleeve 22 corresponding to a maximum diameter of socket 25.
  • the rotary spacing device 26, secured to the outer sleeve 20, comprises a cam member 28 in contact with which the angle formed by the holding lug 24 and the axis of the inner sleeve 22, decreases to adapt the male connection device to a diameter female socket bottom.
