Definitions

  • the present invention relates to the field of electrical connectors, consisting of a fixed base and a movable plug, made of insulating material, and supporting both of the contact elements made of conductive material, the shape of which complementary ensures, by mutual penetration during insertion, the desired electrical connection.
  • Such connectors are widely used, but their use in certain areas of operation, such as telephone exchanges for example, entails special requirements, such as the guiding of the plug relative to the socket during the 'manual insertion operation, associated with a locking thereof at the end of this operation.
  • a second difficulty results therefrom, linked to the existence of the locking device itself, the short distances between plugs making manual access and unlocking complicated, a preliminary operation the necessity of which has been shown above.
  • connection base for an electrical circuit comprising on the one hand a fixed base and a movable plug, both provided with conductive elements of complementary shape making the electrical connection, and on the other hand a device for locking the plug on the base, the connection and / or disconnection of the circuits being obtained respectively, by plugging and / or extraction by manual action on gripping surfaces carried by the movable plug.
  • the locking device comprises a fixed keeper carried by the base and a movable bolt carried by the plug, fixed to a first end of a lever provided with one of the gripping surfaces, the unlocking control member being constituted by one of the surfaces gripping. The second end of the lever is attached to the top of the plug.
  • Such a base comprising a channel as a keeper, located directly on the base of the base in cooperation with a lever at the end of which is the bolt, cannot be used for locking a plug on its base in telephone exchanges where the bases of the bases are arranged at extremely reduced mutual distances for reasons of space.
  • Such a solution in fact requires either a lateral slot having a large-width strike function to allow sufficient clearance of the lever and the bolt, or a lever-blade holder of thickness so small that its rigidity and solidity would be very seriously affected.
  • the locking means are gripped on the sides, which requires sufficient space to introduce the fingers on the gripping surfaces.
  • connection bases known from the prior art do not make it possible to solve the problem of manual gripping and simultaneous unlocking during the juxtaposition of a plurality of bases of this type allowing a high density of connections.
  • the base according to the invention provides a solution to the problem posed. It is characterized in that the lever is fixed by its second end to a support provided with another of the gripping surfaces, said support being arranged projecting in the direction of extraction relative to the movable plug, and in that the fixed keeper of the locking device is fixed to the end of a keeper support.
  • FIG. 1 represents a known connection base, of the "inverted DIN male” model, equipped with a locking device for the mobile plug of known type.
  • the base consists of a fixed fixed part or base 1, of parallelepiped shape and of a movable plug 2, both carrying conductive contacts such as 3 and 4, realizing the electrical transmission between the wires , such as 5 and 6, circuits to be connected.
  • the base 1 is parallelepipedic, and has an open access face 7 to allow plugging in, one of the edges of which has a protruding rim 8 in which a channel 9 has been made opening out on each side thereof.
  • This channel is intended, as explained above, to receive a lock, in the form of an elastic band or blade, one end 10 of which is designed to be inserted therein and fixed therein, thanks to the harpoon 11 and bearing pins such that 12.
  • the other end 13 is provided with a bolt 14.
  • the movable plug 2 is, for its part, provided with a strike 15. When plugging in, the bolt 14 enters the strike 15, and the locking is achieved.
  • Such a base has the drawbacks described in detail above, namely the need for two separate stages during unplugging, and the risk of accidental unlocking by tilting the movable plug in the direction of the latch away from the striker. .
  • FIG. 2 shows another known embodiment of the locking system, fitted to a base of the "inverted DIN male” model.
  • the base 1 comprises the known channel 9, which in this case is implemented, by its lower face, as a strike for the lock 20, the bolt of which is carried by a pivoting lever 21 secured to the movable plug 2.
  • Locking takes place by the elasticity of the articulation 23, and the unlocking is controlled by the action of a slide 24, carrying at one end an inclined plane 25 cooperating with an inclined plane 26 carried by the latch 20, and at the other end a data entry plate 27.
  • the lock can be locked in the locked position by pressing one of its parts 28 with a locking hook 29 carried by the slide.
  • the device ensures the transmission of the unlocking command above the mobile plug, which is useful in telephone exchanges, but on the other hand always requires two separate steps to unlock.
  • the lower edge 30 of the rim of the base 1 degrades quickly after a few plugs, and the base itself must be replaced.
  • FIGS. 3 and 4 represent, according to two variants, a first embodiment of the connection base of the invention, in the case where the bases are used in large numbers in equipment, with very short distances, both between the long sides and between the short sides. The introduction of the fingers between two bases for manual gripping is then made impossible.
  • a lock is implemented, the static or strike part of which is carried by a strike holder 51, the length of which, counted in the direction of insertion, is made greater than the height of the movable plug 2.
  • the channel 9 of the base serves as an attachment receptacle for the static part of the strike holder 51.
  • the fixing is carried out by a harpoon 11 and bearing faces such as 35.
  • the active part of the bolt holder of the bolt in the form of lever 52, pivoting elastically at 53, is itself carried to the end of a support 54 surmounting the housing, the length of which, counted in the direction of insertion, is chosen sufficient to allow easy gripping on the surfaces 55 and 56, grooved for better grip of the fingers.
  • Figures 3 and 4 correspond to the case where the direction of the pivot axis is respectively parallel and perpendicular to the long portuer side of the channel 9 of the base of the base (not shown in the figures).
  • Figures 5 and 6 show a second alternative embodiment of the invention, making the striker holder 51 an additional function, that of guiding the plug during insertion.
  • the plug carries, facing the keeper, complementary members in the form of a slide such as 71 and 72, cooperating by sliding with the keeper 51; chamfers such as 63 and 64 facilitate placement.
  • connection bases while being extremely close together, are furthermore arranged in the bottom of deep chassis, for example of those of the so-called "backplane" type.
  • the role of the plug-in guide thus assumed by the same means as that which participates in the locking and unlocking of the movable plug, thus provides, in a manner which is not evident from the state of the art, a set of results contributing to a common goal of improved operational efficiency and reduction in manufacturing costs.
