  The end of the wall 35c, opposite the wall 35a, is extended by a plate 40 provided, on the one hand, with a hole 41 for the passage of a stud 4 and, on the other hand, with a opening 42 intended to receive a hook 2, said plate 40 being provided, between hole 41 and opening 42, with a locking stop 4335 having a ramp 43a and a steep 43b (see figures, 7 and 13). The edge of the wall 35d is also extended by a plate 44 pierced with an opening 45 intended

to receive a hook 3.

  The wall 35e is provided with an opening 46, while the wall 35a has a slot 47 which extends from the opening 46 to the vicinity of the wall of

floor 35d.

  When the modules 35 are put in place, the tongues 21 and the wings 20 extend inside

of said modules.

  Each module 35 is intended to receive a support 50 of a fuse 51 having two contact pads 52 and 53 connected by a fuse wire housed in an insulating body. The support 50 (see Figure 11) consists of a body of insulating material comprising two compartments 71 and 72 separated by a veil 73 intended to be inserted in the slot 47, the first compartment 71 engaging in the opening 46 and comprising, on its side wall 117, a locking stop 118 having a ramp 118a

and a steep 118b (Figure 11).

  The first compartment 71 is intended to receive an electrical connection member 55 formed from a plate which is a good conductor of electricity conveniently cut and folded to present a first clamp 56 formed of a bottom 58 and of two folds 57 of which

  the free edges cooperate with the bottom, the tongues 21 being intended to be inserted in this clamp.

  The electrical connection member 55 also has a second clamp 59 having a section body

  rectangular 60 with extensions 61 folded inside

  laughing body which is provided on one of its faces with an opening 63. The second clamp 59 is intended to receive

  one of the contact pads 52 or 53 of the fuse.

  The first compartment 71 comprises, in one of its side walls 75, an elastic tab 76 terminated by a hook 77 projecting inside the compartment which is open at its lower end and whose upper end, also open, is bordered by a rim 78. The electrical contact member

  abuts by the free end of the clamp 59 against the flange 78.

  The second compartment 72 is open at its upper end and at its lower end and it is intended to receive a female electrical contact member 80 (see FIGS. 10 and 12). This member 80 has, at one end, tabs 81 for crimping a

  stripped end of an electrical conductor 83 and tabs 84 for crimping the latter.

  The member 80 is shaped to present a body of rectangular section whose long sides are extended and folded inside said body to form an elastic clamp 85 intended to receive one of the studs.

  contact 52 or 53 of fuse 51, one of the short sides 87 of the body being pierced with an opening 86, while one of the adjacent sides 88 is cut to form a retaining tab 89.

  The second compartment 72 internally comprises an elastic tab 90 having, in the vicinity

  from its free end, a projection 91, a free space 9235 being formed between the elastic tab 90 and the corresponding internal wall 93 of said compartment 72.

  On the internal wall 94 of the second compartment

  ment 72 is formed a groove 95 with a stop 96, while the upper end of said compartment 72 is provided with a flange 97 constituting a stop for the member 80.

  The member 80 is inserted in the second compartment

  ment 72 so that its end provided with the clamp 85 bears against the rim 97, while the retaining tab 89 is engaged in the groove 94 and bears

  against the stop 96, the projection 91 being inserted into the opening

  re 86. The member 80 is thus blocked in the compartment

  72, but so that it is perfectly locked, a key 100 is provided (see FIG. 12) which is inserted into the free space 92. This key is made up

  by a flat plate which, at one end 101, is cut out

  sword to present two slots 102 determining tongues-

  your elastic bands 103 provided laterally, each with a

  projection 104 in the vicinity of their free end.

  Compartment 72, in free space 92,

  presents notches 105 intended to receive the sail-

lees 104.

  It is understood that, when the key 100 is put in place, the elastic tongue 90 can no longer

  play and thus the electrical contact member 80 is locked in the compartment 72.

  The support plate 1 has two projections 107 in the form of a dovetail, the free ends of which

  are terminated by hooks 108.

  The housing element 5 comprises a housing 110 with a bottom 111, two side walls 112 and two hooks 113, the terminal 15 comprising a head 115 which is placed in the housing 110 and which is located

  locked in the latter by the hooks 113.

  The support plate 1 receives first the head 115 from the terminal 15, then the contact strip 9 of which

  holes 10 and 13 are crossed by the respective pins

  4 and 7, while terminal 15 crosses the opening

  ture 14 and receives the terminal 16 set at one end of a

  conductor 17, the nut 19 then being tightened.

  The terminal 15 is hidden by the complementary housing element 25, the hook 28 of which cooperates with the core 29 and the bosses 26 with the hollows 27.15 The modules 35 are assembled side by side by engaging the projections 37 in the grooves 39 so

  that the hooks 38, by means of a slight elastic deformation, cross the stops 36 and ensure the ver-

  rusting of said modules together.

  The set of modules 35 thus formed is fixed to the support plate 1, on the one hand, by the end module, the grooves 39 of which receive the projections 107 and the hooks 108 and, on the other hand, by the hooks 2 and 3 which are inserted respectively in the openings 42 and 45. The pins 4, by engaging in the holes 41, make it possible to center the modules so that the wings 21

  thus housed in the modules are located exactly30 to the right of the openings 46.

  The electrical connection members 55 are housed in the supports 50 and wedged in the compartment 71

  by the hooks 77 which penetrate into the openings 6335 and the flanges 78 against which the free ends of the clamp 59 come to bear.

  The female electrical contact members 80 are placed in the compartments 72 and locked by the hooks 91 engaged in the openings 86, the tongues 89 bearing against the stops 96, and by the keys 100 inserted in the free spaces 92. The fuses 51 are then placed and their stud 53 are inserted in the clamp 55, while the other studs are engaged

in clamp 85.

  The supports 50 are then, by the part delimiting the compartment 71, engaged in the openings

  46, the web 73 fitting into the slot 47 and the lock

  lage of the supports 50, on the modules 35, being provided by the stops 43 and 118. Indeed, during the engagement

  of the web 73 in the slot 47, the ramps 43b and 118b slide

  smells on each other until the steep 43a

  and 118a coincide (see Figure 13).

  Of course, the invention is not limited

  to the embodiment which has just been described and shown

  smelled. We can make many modifications

  detail without departing from the scope of the invention.
