Definitions

  • the present invention relates to an intermediate connection device arranged between wires of a network and a connection element for an electrical appliance and / or a data processing unit.
  • connection boxes are mounted directly on sections of a network by conventional means which generally consist in interrupting the wires of this network and in ensuring the connection by screwing or clipping in contact elements provided in the boxes.
  • connection boxes are designed to be permanently mounted and changing or replacing them is a relatively complicated operation.
  • the present invention proposes to overcome this drawback by providing an intermediate connection device as defined in the preamble and arranged to allow easier and faster replacement of a connection box, this replacement can also be done without interrupting the network supply.
  • the device according to the invention characterized in that it comprises a body, at least one contact plate provided on the one hand with means for connection to a network wire and, on the other hand, with a opening for receiving connection means of a socket contained in said connection element.
  • connection means of the socket advantageously comprise an elastic end piece designed to removably engage in the opening of the contact plate. Thanks to the elasticity of this tip, the contact between the edges of the opening provided with folded tabs and the elastic tip being ensured.
  • the intermediate connection device 10 is disposed between the wires 11 of a network, which can be a distribution and transport network of electrical energy and / or a data transfer network, and a element 12 for connecting an electrical appliance and / or a data processing unit.
  • the connection element 12 comprises a housing 13, the upper face of which is for example equipped with three openings 14 for the passage of the pins (not shown) of a connector of an electrical appliance. Inside this housing are mounted three conductive sockets 15 arranged in correspondence with the three openings 14 and housed in molded cells of the housing. These sockets are designed to receive said pins of the connector.
  • the intermediate connection device 10 comprises a body 16 in which are mounted contact plates 17 which have a double function.
  • Their first function is to provide a fixed electrical connection by connection to the wires of the network.
  • Their second function consists in ensuring a removable electrical connection by connection of the sockets 15.
  • the contact plates 17 are provided with openings 18 arranged to cooperate with elastic end pieces 19 which equip the sockets 15 by extending them downwards. .
  • the elastic ends 19 and the openings 18 are designed to cooperate in order to ensure said second function, namely the removable electrical connection between the sockets 15 and the contact plates 17.
  • the first function can be ensured of the quick connection members known per se, such as for example self-stripping connection elements or the like, which will be described in more detail below.
  • the contact plates 17 are advantageously overmolded in the body 16 which has, on its upper face, openings 20 for access from the elastic ends 19 to the openings 18 for the contact plates 17.
  • the intermediate connection device 10 is designed to be fixedly installed on the network and the connection element 12 is designed to be able to be quickly and removably installed on the intermediate connection device 10.
  • the replacement of the connection element 12 is easy and can be done by a person not specially trained and without any interruption in the operation of the network, for example by cutting the current.
  • FIG. 2 represents, in perspective view, an embodiment of the elastic end piece 19 associated for example with a socket 15 defined above
  • FIG. 3 represents, in perspective view, an embodiment of a contact plate 17 provided with an opening 18.
  • the elastic end piece which is a contact piece, is produced by cutting-forming from a strip.
  • This nozzle essentially comprises an arm 19a for connection between a support element 19b which may be integral with a socket 15 or the like and an elastic spout 19c bent approximately at 180 ° relative to the linkage arm.
  • the opening 18 is formed by stamping cutting of the contact plate 17.
  • two tabs 18a and 18b are formed along two opposite sides of the rectangular opening 18 and folded down. In the example shown, they are formed along the two opposite longest sides of the opening 18.
  • These tongues can have a certain elasticity, but can also be rigid to oppose a predetermined resistance to the penetration of the elastic end-piece. 19.
  • FIGS. 4 and 5 are section views.
  • the elastic spout 19c forms a non-zero angle with the connecting arm 19a, so that the maximum spacing of these two components is greater than the transverse dimension of the opening 18.
  • the two components come closer because of the elasticity of the elastic spout 19c. Therefore, the mechanical strength of the elastic end piece 19 relative to the contact plate is well ensured.
  • Figures 6, 7 and 8 show an alternative embodiment of the elastic end piece 19.
  • the end piece shown differs from the elastic end piece described above in that the elastic nose 19c has two bosses 19d having the effect of improving the contact resistance with the tabs bordering the opening 18 of the contact plate 17. It can be seen in FIG. 8 that the support of the elastic spout 19c against the tab 18b and, consequently, the electrical contact, is effected by through the bosses 19d. These bosses create an additional thickness, so that the bearing stress is reinforced on the elastic spout when the end piece 19 is engaged in the openings 18 of the contact plate 17.
  • Figures 9 to 12 show another embodiment of an elastic tip 19 intended to be engaged in an opening 18 of a contact plate 17.
  • the openings 18 have a circular shape instead of being rectangular , which eliminates the problem of the orientation of the elastic tip 19.
  • the end of the connecting arm 19a and the elastic spout 19c have a symmetrical curved shape. They are provided with protrusions 19e which constitute stop means limiting the deformation at the time of the introduction of the elastic end piece 19 into the corresponding opening 18 of the contact plate.
  • This embodiment makes it possible to settle two questions which are, on the one hand, that of pre-orientation of the elastic tips and, on the other hand, that of limiting the deformation at the insertion of these tips.
  • the first question is settled thanks to the circular shape of the openings 18 and the circular shape of the elastic end pieces when the elastic spout 19c is pushed against the end of the arm 19a.
  • the second is set thanks to the presence of the 19th protrusions.
  • FIG. 13 is a perspective view showing an embodiment of a socket 15 provided with an elastic end piece 19 provided with two bosses 19d as shown in FIG. 7.
  • FIG. 14 is a perspective view illustrating an embodiment of a contact plate 17 provided with an opening 18 and with a self-stripping connector 30.
  • This connector comprises two forks 31 and 32 which delimit two slots 33 and 34 respectively between the claws 31a and 31b of the fork 31 and 32a and 32b of the fork 32.
  • Figure 15 shows, seen in section, the intermediate connection device mounted on a circuit and associated with a connection element.
  • This device 10 contains, in the example shown and in order not to clutter the figure, a contact plate 17 associated with a self-stripping connector 30 mounted on a cable 11.
  • a socket 15 contained in a connection element 12 comprises a elastic tip 19 which is engaged in the opening of the contact plate.
  • the number of sockets placed in the housing 13 depends on the number of openings made in the front face of this housing and finally on the intended use. This number is for example three for single-phase current with an earth line. It can be four for a telephone line.
