Definitions

  • the present invention relates to an electrical socket base with a safety device, which has significant characteristics of novelty and inventive activity compared with the type which is currently known.
  • the socket base which is the subject of the present invention belongs to the type of socket bases which have safety means to prevent introduction of foreign bodies into the contact holes or alveoli for the pins or spigots.
  • These safety devices are designed to prevent accidents caused by the introduction of electrically conductive components into the interior of the socket bases, for example inadvertently, or by actuation by children etc.
  • the object of the present invention is to provide an electrical socket base which is provided with a device which has safety characteristics such that it is not possible to penetrate the inlet of any of the contact alveoli in order to accommodate the contact pins, by acting on only one of these alveoli.
  • the object is to provide a safety device which in order to be opened, requires balanced and simultaneous actuation of both contact alveoli, since if this action is carried out on only one of the alveoli, it is not possible to gain access to the internal contacts, and thus accidents which are possible at present can be avoided.
  • the socket base which is the subject of the present invention is of the type which has a gliding or sliding part, which is connected in the interior of the socket base, and is subjected to the action of antagonistic springs which maintain this slide opposite the inlets for the pins, such that the inlet of the corresponding alveoli is closed, but opening takes place automatically when a male-type plug is presented and introduced, since the pressure of the pins of the latter gives rise to opening of the safety slide.
  • This type of slide is known from European patent application 94301773.
  • the present invention is based on the principles described in the aforementioned patent, and facilitates the means wherein the slide can be displaced only when simultaneous, balanced actuation takes place by the male plug in the two contact alveoli, but displacement of this slide is prevented if the actuation takes place in only one of these alveoli.
  • the present invention thus comprises an assembly formed by the cover of the socket base, and a slide with two arms which is accommodated in the latter, such that this slide is guided with a specific amount of play, and can strike against some fixed stops, such that if an eccentric thrust action is produced, in other words on only one of the alveoli for the contact pins, this slide is displaced slightly and undergoes slight rotation, which makes a fixed stop of the aforementioned cover intervene relative to a part of this slide, such that the latter cannot continue its displacement, and the inlet cannot be penetrated in order to establish contact in the socket base.
  • the separation between the rear edge of the slide and the edge of the inlet apertures for the pins is designed to be greater than the path to be travelled by the stop parts of the slide on the corresponding reception area of the socket cover.
  • the opposite areas both of the contact parts of the slide, and of the reception areas of the cover of the socket base have slight inward inclination which tends to produce a specific transverse force of closing the arm which has made contact with the slide.
  • the socket base with a safety device comprises a closing cover 1, which in its interior accommodates a slide 2, which is generally in the shape of a "U”, with parallel arms 3 and 4, and a rear projection 5, and is housed in bosses of the cover 1, which are delimited by a projecting edge 6, which closes the bosses on the exterior.
  • the slide 2 is faced by the sides of a main section, which position the arms 3 and 4 relative to the apertures 7 and 8, which correspond to the position of the contact pins, such that in the closing position shown in figure 1, the contact pins cannot be introduced, since this is prevented by the slide 2 which is opposite the apertures.
  • some flanges 10 and 11 in the interior of the cover 1 are designed to carry out accurate guiding of the respective inner sides 12 and 13 of the arms 3 and 4, when the slide 2 is advanced by the aforementioned mechanism, i.e. by the thrust of the contact pins.
  • the dimensions of the arrangement of the flanges 10 and 11 relative to the inner faces 12 and 13 are such as to permit accurate adjustment with sliding movement, but with very little play between these components.
  • the displacement of the slide must take place in a manner which is straight and without lateral deflections.
  • the rear projection 5 has a straight internal groove 50 which is parallel to the sides of said projection, said groove narrowing to form the groove 51 which has a smaller cross section, forming the hook-like steps 52 and 53.
  • the cover has a rib 54 straight and coaxial with grooves 50 and 51 having in its end a V form indentation 55, which two sides are liable to abut respectively against stops 52 and 53 in case that a deviation of the slide should occur in its operation. It is precisely by acting on this principle according to the present invention, that off-centred actuation of the slide is prevented.
  • the slide is mounted such that the rear projection 5 is guided by the inner faces 14 and 15 of both partitions of the interior of the cover 1, with a specific play or gap, such that slight rotation of the slide along its own axis is possible, i.e. along an axis which is perpendicular to the plane of the drawing, when actuation takes place with only one of the contact pins in only one of the apertures 7 or 8.
  • the slide is pivoted slightly on its own axis, owing to the action of the spring, such that one or another of the quoins 16 and 17 of the inner faces 12 and 13 of the arms 3 and 4 strike against one or the other of the steps 18 and 19 which exist in the initial section of the flanges 10 and 11.
  • the slide 2 cannot advance.
  • one of the sides of the indentation 55 will colide against one or the other of the corresponding steps 52 and 53 as shown in Figure 16.
  • the slide 2 can advance only when actuation takes place simultaneously by means of the two contact pins of a male socket in the apertures of the connection base 1, since otherwise the slide cannot be displaced and a component cannot be introduced individually in a single one of the contact alveoli, thus preventing this possibility of accidents.
  • the separation "x" in figure 2 bis between the rear edge of the slide and the edge of the inlet apertures 7 and 8 for the pins is designed to be greater than the path "y", figure 1 bis, to be travelled by the parts of the stop 16 and 17 of the slide on the corresponding reception area of the cover of the socket.
  • integrated antagonistic springs are provided, for example the spring 26, which acts on internal L-shaped strips 20, which are provided with two arms 22 and 22', the former being supported in the interior of the body 23 of the socket base, which in the case in question can correspond to an adaptor device which supports external contact pins 24.
  • the spring 26 is slightly inclined and supported on a stamped part of the arm 22, by this means obtaining more efficient action.
  • the end of the arm 22 is accommodated in the interior of a slot 25 of the slide 2.
  • the contact by the contact pins to be introduced via the apertures 7 and 8 is obtained firstly by the arm 22 of the strip 20, and secondly by the parallel arm 27 of a second strip 28, the other arm 21 of which is adapted to the interior of the body 23. Both the strip 20 and the strip 28 are secured at the end 29 of the contact pin 24.
  • each of the latter receives the double contact produced for example by the arms 22 and 27, which receive this contact pin between the two of them.
  • Figure 5 shows the springs, which are numbered 26 and 26', corresponding to the two contacts.
  • the central spring 30 is designed for the earthing contact.
  • the slide 31 is subjected to the action of helical springs 32, which are partially accommodated in apertures 33 of the arms, for example that which is indicated 34 in figure 11.
  • This version corresponds to a socket base in which there are no internal strips, as shown in figure 2 and the successive figures. This corresponds to a version with flat pins 35, 36 and 37.
