Definitions

  • the invention relates to an electrical connection device formed by a base active and a plug provided with at least one contact which is intended to cooperate with a antagonistic contact of the base arranged in an insulator, which insulator is provided with minus one passage for the introduction of said plug contact during coupling of the latter with the base.
  • connection devices concerned by the invention are in particular the sockets, extenders and connectors.
  • connection devices present many problems with solve according to their applications and in particular security problems.
  • a finger is used articulated test defined according to a standard.
  • the tests consist in not being able to make contact between the finger standard test and the live parts of the device to be tested by attempting to introduce the test finger in all possible positions, these tests being all the more difficult to satisfy that the currents used are of high intensities.
  • a plug should not be able to mate with a base only insofar as there is electrical compatibility between them so that the currents and / or voltages and / or electrical powers correspond by one connecting element to each other.
  • connection devices require or recommend the use of pilot contacts intended, for example, to remotely control the current flow.
  • pilot contacts intended, for example, to remotely control the current flow.
  • the space required for pilot contacts is often insufficient in conventional devices, in particular for connectors unipolar.
  • the inventors have imagined a contact which makes it possible to resolve in at the same time several of the problems posed.
  • connection device of the aforementioned type of known art, formed by an active base and a plug provided with at least one tubular contact which is coaxial with the direction coupling of the plug and the base, and which is intended to cooperate with a contact antagonist of the base arranged in an insulator, which insulator is provided with at least a passage in the form of an annular groove for the introduction of said contact the plug when the latter is coupled with the base, this device being particularly remarkable in that each contact of the base is under the form of an axial pressure contact, that each passage of the insulation in the form of annular groove is intended for the passage of a single contact of the plug while being in in addition to at least partially opening axially in the zone of said contact of the base, while each contact on the plug cooperates with the corresponding contact on the base, by at least part of the edge of its front end which is applied on said base contact.
  • such a tubular contact and the annular groove of the base can at the same time constitute mechanical coding means of compatibility between the plug and the base since then so that a plug can mate with a base, the tubular contact of the plug must be introduced into the annular groove of the base.
  • One or more tubular contacts also allow coupling of the elements without compulsory angular orientation of the plug and the base, which is very advantageous, especially with the use of large cables since it avoids any twisting.
  • one or more tubular contacts also allow to clear a space free interior in each contact that we can take advantage of, for example to have it pilot contacts.
  • connection devices multipolar or not it is particularly interesting to constitute a device unipolar connection in the sense of power contacts, and in particular for high intensity currents.
  • the plug and the base only have one contact apart from any pilot contacts, the plug contact being for example provided with a crimping head in or on which a cable is crimped.
  • This mode of unipolar realization which is the solution to the original problem submitted to the inventors, still shows the fundamental difference compared to the known art of aforementioned documents DE-196 38 157 or US-5,759,069 A whose purpose is to allow on the contrary, in a limited space, to realize a multipolar device.
  • connection device formed by a base and a cooperating plug, it also further relates to a plug or socket separately intended to constitute such a connection device.
  • connection device unipolar that is to say that the plug 1 and the base 2 which constitute it do not include each one power contact (phase, neutral, earth, ).
  • a device of the extension type is shown here, that is to say with a base and a plug, both mobile, the base constituting according to vocabulary of international standards, a mobile outlet.
  • the base and the plug extension are intended to mate by various mechanical means to establish an electrical connection between their contacts.
  • base could be fixed to constitute the base of a socket outlet according to the vocabulary of international standards, or on the contrary, the plug could be fixed and constitute the base of a connector according to said standards.
  • Sheet 1 includes, as the drawings clearly show, a tubular casing 3 in the interior space of which is therefore arranged in this example, a single contact 4 of power in the very particular form of a ring or tube entirely in conductive material.
  • the base 2 is also provided with a casing 5 intended to receive the casing 3 of the plug which is inserted into said base casing during coupling.
  • the base 2 has inside its casing 5, an insulator 6 which protects access to a contact 7 of the base ( Figures 3 and 4).
  • the contact 7 of the base 2 is here in the form of a flexible blade offset, forming a spring and / or provided with a spring.
  • Contact 7 of the axial pressure base is accessible to contact 4 of the plug by means of a passage 8 formed in the insulation 6 of said base so that the end edge of the tubular contact can be applied to the contact of the base so as to form an end contact under pressure.
  • the passage 8 of the base 2 has the form of an annular groove which is at least partially opened axially opposite the contact 7 of said base.
  • the tubular contact 4 of the plug is here provided with a crimping head in or on which a cable 9 is crimped (Figure 1), the base being also provided here with a cable 10 (figure 3).
  • the plug 1 of Figures 1 and 2 can only mate with the base 2 of Figures 3 and 4 only on condition that the diameter and thickness of the tubular contact 4 of said plug corresponds to the diameter and respectively to the thickness of the annular groove 8 of the insulator 6 of the base 2.
  • one of the many advantages of such contact tubular 4 makes it possible to release a free space which can be used in particular for have for example one or more pilot contacts (intended for example to control remote current flow) like the coaxial pilot contacts 11 and 12 of the sheet 1, shown in Figures 1 and 2 and which are intended to cooperate with antagonistic contacts 13, 14 of the base 2 ( Figures 3 and 4).
  • the pilot contacts 11, 12 of the plug 1 pass in this example through a additional passage 15 provided in the insulation 6 of the base 2 ( Figures 3 and 4).
  • the invention relates to many other embodiments than the one described, to one or more contacts.
  • the or the tubular contacts of a plug associated with the annular groove or grooves of a base, offer the advantages already mentioned about finger protection standard test, the or each passage 8 in the form of an annular groove of a base being intended for the passage of a single tubular contact 4 of the plug corresponding.
