Definitions

  • the present invention relates to an interconnection box modular intended more particularly for the automotive industry.
  • the fuses they are of the type called flat fuse that is to say comprising two flat connection tabs, connected by one of their ends of a wire which is the fuse properly and which breaks when the temperature exceeds a predetermined intensity or amperage value, or of the type constituted by a blade which is in contact with terminals of fixed connections, are generally arranged in boxes which are supplied with electric current by the battery of the motor vehicle.
  • Each electrical cable or cable bundle intended for an electrical control function predetermined is connected to the interconnection box, then we proceed to positioning or mounting of the various fuses, after which the box of interconnection is mounted in a space reserved for this purpose either in the engine compartment, or in the passenger compartment of the vehicle.
  • the indication amperage of the fuses is performed on the fuse body when it it is a flat fuse or on the fuse when it is a blade.
  • the object of the present invention is to remedy the drawbacks mentioned above and to propose a modular interconnection box which is able to adapt to a large number of fuses likely to be used in a wide range of vehicle models.
  • the present invention relates to an interconnection box modular comprising a support on which are formed at least two receptacles capable of each receiving a module which includes a fuse, each module being on the one hand connected to an electric cable of which one end is connected to said fuse of said module and secondly supplied in electric current from an electrically conductive blade mounted on said support and connected to a source of electric current.
  • An advantage of the present invention lies in the fact that the interconnection box can be connected to the complete harness, control fuses that can be made before mounting in said box interconnection because it becomes possible to carry out this control directly on each independent module. It follows that the cable or harness cables which is directly mounted in the module can also be checked before installation in the interconnection box. Therefore, the final assembly time is considerably reduced and control in final assembly is no longer necessary since it is performed module by module before final assembly.
  • Another advantage is that it becomes possible to provide a structure of the interconnection box which adapts particularly well to various functions provided in the vehicle. Indeed, the case may include more receptacles there are no modules, so add one or more modules additional options corresponding to the options chosen in the vehicle, without that it is necessary to dismantle said interconnection box for the fitting new fuses and / or checking additional after fitting the new fuses.
  • modules can be housed in any receptacle, even those that are unoccupied since all the receptacles are crossed by a conductive blade.
  • the conductive strip comprises a first part arranged to receive blade fuse modules and a second part arranged to receive fuse modules pluggable.
  • retractable means such as a flexible tongue or a clip, blocking access to the fuse blade when the module is not in place in its receptacle, cooperating with an element of the receptacle for retract and free access to the blade when the module is in place.
  • identification can be made by the given external appearance of the module, for example all the identical sizes being of the same color or bearing a mark given on the body of the module. Likewise, we can also identify, by appropriate marking, the nature and section of the cable corresponding to each module.
  • the invention even makes it possible to do without completely of identification when assembling each cable with its module, because a cable assembly line is provided, with its module, a fuse and a cover (only one reference per component).
  • the interconnection box whose protective cover is not not shown, includes a general support 1 on which is fixed, by any suitable means, a conductive strip 2 which is supplied with current at from a source, not shown, which is for example a battery of a motor vehicle.
  • Modules 3, independent of each other, are intended to be mounted in receptacles which, in the example in the figure, are delimited by locations made on said support 1.
  • Each module 3 comprises a hollow body 4 divided into two parts 5, 6, one of which part 5 receives a fixed connection terminal 7 constituted by an insert molded.

  • a terminal 8 On the support 1 and on each side a terminal 8 are provided with two guide and retaining studs 17 which each have one end in the form of a flexible hook 18 forming a retaining clip intended to come to bear on a notch 19 formed on the upper edge of the corresponding groove 16, so as to maintain in places the body 4, once it is inserted between two consecutive pads 17, which delimit between them the location for housing the body 4, this location constituting a receptacle 3a for a module 3.
  • the fixed terminal 7 comprises a base overmolded in a stud in plastic 20 which is housed in a corresponding blind hole 21 formed in holder 1.
  • each cable 10 is produced by the conductive strip 2, the terminal 8, the fuse 9 and the fixed terminal 7.
  • the support 1 and the conductive strip 2 are identical to those of FIG. 1 and the modules 22 have flat fuses 23, as shown in Figure 3.
  • the receptacles 24 for the modules 22 are formed in a receiving assembly 25 comprising a number of receptacles 24, six in the example in Figure 2, which are overmolded on the right side of blade 2.

  • the body 41 also includes a part 45, in the shape of an inverted L, which comprises at least one element of link or clip 46 which cooperates with a notch 47 formed in the cover 42.
  • a part 45 in the shape of an inverted L, which comprises at least one element of link or clip 46 which cooperates with a notch 47 formed in the cover 42.
  • the part 45 also serves as a stop for the module after positioning in the corresponding receptacle.
  • a seal 48 is mounted around of the body 41 and is housed in a peripheral groove 49 formed in the cover 42; alternatively, the seal can be housed in the cover 42 and come lean on the body 41.
  • a locking jumper 50 is provided for block the clips 46 after their positioning in the notches 47, so as to avoid any lateral displacement of the cover 42 relative to the body 41.
  • a reception assembly 51 for the modules 40 can be formed directly in or attached to the support 1. It is more advantageously overmolded on the blade 2.
