Definitions

  • cigarette lighter sockets There are many electrical or electronic devices such as household appliances, telecommunication equipment, audio devices, video devices, etc., intended to be connected to a female socket, in particular of the cigar lighter type of motor vehicle.
  • the diameter of these cigarette lighter sockets not being a world standard, it depends on the country of manufacture of the vehicle. For example, vehicles manufactured in Europe generally have a cigarette lighter socket whose diameter is greater than that of the cigarette lighter sockets of vehicles manufactured in the United States and Japan.
  • a male connection device adaptable to different diameters of cigarette lighter socket is known from patent GB2293054A.
  • This device consists of an internal sleeve and an external sleeve.
  • the external sleeve is provided with at least one retaining tab capable of laterally deviating from an initial position by a spacer, when one of the sleeves slides relative to the other in a relative movement longitudinal. This spacing then increases the outside diameter of the male connection device until it reaches the appropriate diameter to hold the device in the cigarette lighter socket.
  • the adaptation of the male connection device to the diameter of the cigarette lighter socket therefore results from a longitudinal sliding movement of a sleeve of said device relative to the other, this movement being in the extension of the insertion movements and extraction of said device.
  • This male connection device has at least one major drawback. In fact, each time the said device is inserted / removed, the spacing of the retaining tab can be modified. Consequently, the adaptation of the diameter of said male connection device to the diameter of the socket must be carried out with each new connection.
  • An object of the present invention is to remedy this drawback to a large extent and to provide a male connection device making it possible to connect an electrical or electronic device to a socket, in particular of the cigarette lighter type, in a reliable manner, such so that the diameter of said device can be adapted beforehand to the diameter of the socket.
  • This rotary spacing device has the advantage of being adjustable beforehand to the diameter of the socket to avoid the user having to make this adjustment with each new connection.
  • a blocking device of the rotary spacer device for blocking the rotation of one sleeve relative to the other.
  • Another object of the present invention is to provide a male connection device less sensitive to possible imbalances caused by multiple insertions / extractions.
  • the adaptation of the diameter of the male connection device according to the invention necessitating a relative rotational movement between the internal sleeve and the external sleeve of said device, the probability that the spacing is adjusted during an action of insertion (resp. extraction) of said device, in (resp. of) the female socket is very low, these insertion / extraction actions being effected during longitudinal movements not requiring a rotational movement.
  • Figure 1 shows an exploded perspective view of the male connection device according to a preferred embodiment of the invention.
  • FIG. 2 represents a perspective view of the male connection device according to the preferred embodiment of the invention.
  • FIG. 3 shows at A, B, C and D four views of the male connection device according to the preferred embodiment of the invention.
  • FIG. 4 represents these same views for a different value of the diameter of the socket.
  • FIG. 5 represents an exploded perspective view of a variant of the preferred embodiment according to the invention.
  • FIG. 6 represents an exploded perspective view of 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, an external sleeve 12 surrounding the internal sleeve 10, at least one tab of retaining 14 disposed outside of the outer sleeve 12, the retaining tab 14 can be conductive.
  • a rotary spacer device 16, integral with the internal sleeve 10, makes it possible to radially move the retaining tab 14 from an initial position, during a relative movement of rotation between the internal sleeves 10 and external 12.
  • the rotary spacer 16 comprises a cam element 18 having a cam profile, so that the retaining lug 14, integral with the external sleeve 12, moves away from its initial position under the action of the element cam 18 in order to adapt the external diameter of the male connection device to the internal diameter of the socket 17 and maintain them in mechanical and electrical contact after insertion.
  • the end of the male connection device comprises an electrically conductive element 19 intended to cooperate with a conductive element of the socket to provide a first electrical contact.
  • a second electrical contact is made on the side walls of the male and female parts of the connection device.
  • a metal device 21 is provided which is elastically pressed towards the outside of the internal sleeve 10 by a return spring 15 and sliding by openings made in said sleeve 10.
  • a printed circuit 11 provides the interface between the first and second contacts described above and the electrical circuits of the device that it is desired to connect to the socket 17.
  • the spacing of the retaining tab 14 under the action of the cam 18 can be obtained by different means. If the natural elasticity of the material does not make it possible to obtain the desired spacing, provision may be made for an elastic return means (not shown).
  • FIGS. 3 and 4 show a good understanding of the mechanism for spreading the retaining tab 14 during the rotation of the cam element 18 relative to the external sleeve 12.
  • FIG. 3 the view shown in A represents a section along the plane [CC] of the view represented in B.
  • the view shown in D represents a section along the plane [BB] of the view represented in B.
  • the view shown in C represents a section according to the plane [DD] of the view shown in D.
  • a locking device 13 consisting of a first series of teeth on the outer periphery of the internal sleeve 10 and a second series of teeth on the internal periphery of the external sleeve 12 is shown in C in FIGS. 3 and 4.
  • This locking device with locking notches 13 makes it possible to maintain the spacing of the tab 14.
  • An enlargement of the detail of the locking notches 13 makes it possible to understand clearly how the sleeves 10 and 12 cooperate during the rotation of the cam 18.
  • FIG. 4 represents the same views as in FIG. 3, the sleeves 10 and 12 having undergone an angle of rotation a relative to one another. We therefore see in Figure 4 how the lug 14 is raised under the action of the cam 18 to vary the diameter of the
  • FIG. 5 represents an embodiment according to the invention in which the retaining tab 14 is disposed longitudinally on the external sleeve 12.
  • the device according to another embodiment represented in FIG. 6 has the same elements than that represented in FIG. 5, with the difference that the roles of the external sleeves 20 and internal 22 are reversed compared to FIG. 5 and that the device comprises an additional element, an elastic return means (not shown) intended to maintain the tab 24 in an initial position forming an angle with the axis of the internal sleeve 22 corresponding to a maximum diameter of female socket 25.
  • the rotary spacer 26, integral with the external sleeve 20, comprises a cam element 28 in contact from which the angle formed by the retaining tab 24 and the axis of the internal sleeve 22 decreases to adapt the male connection device to a smaller diameter female socket.
