Description

The present invention relates to a connection device

  intended to be fixed, preferably but not exclusively

  on the housing of a household appliance for the purpose of receiving the terminals of the power cable in order to make the connection between the outer cable and the interior of the appliance. Thus, if it is necessary to change the cable due, for example, to a

  mechanical or electrical fault, this operation may be carried out

  killed without the need to access the inside of the device

  machine, and, therefore, without the obligation to intervene

  the electrical installation of the appliance or

  Such an operation may be carried out by an electrician

  or even by the user of the device if it has a

minimum manual skill.

  The device described in this application consists of

  a junction box including wire clamps on the

  which conductors of a cable can be fixed, the terminals being in adequate number, as for example and frequently, two

  restraint of the cable body at a point close to the ex-

  connected trenches, so that traction exerted on that

  An embodiment of the present invention is hereinafter described by way of example with reference to the accompanying drawings, in which: FIG. 1 is a front view of the new device with its cover and a separate retainer FIG. 2 is a plan view in projection

  dirty device and some of its constituent elements.

  The reference numbers cited in the description that follows

  correspond to the numbers indicated on the drawings.

  In the case of an application on a household appliance or the like, the housing 1 is pierced by a rectangular opening in which is introduced an orthometric shaped box 2 of an insulating material and having a flange 3 extending on the periphery of its open end face, the rim on which is fixed the cover 4, the latter being rectangular and having a rim on its periphery and a projecting portion 5 which

clings behind the edge 6.

  Inside the box 2 are provided clamps

  son which comprise the terminals 7, the screws 8 and the nuts 10, these being arranged in housings provided in the upper part, partitions 9 being provided to separate the

  An extension 11 to the top of the body 2 also includes

  partitions 29 for separating the incoming conductors

  in the body of the apparatus or machine on which the

  positive link has been fixed, the said conductors being fixed

  by their ends at the upper ends 12 of the terminals 7.

  Element 13, in the form of a stirrup, serves as

  means of retaining the power cable and has two

  tubular arrangements 14 each for receiving a screw

  both the fixing of said element in cooperation with the holes made in the tubular extensions 16 of the rear face of the body 2 The fortuitous separation or the loss of the element 13

  is avoided by means of plastic connecting wires 15.

  The inner section 7 of the body 2 and the central section 18 of the element 13 delimits a space 19 in which is clamped the

  power cable, the ribs and grooves provided for

  in these sections contributing to the restraint effort.

  The projection 20 at the bottom of the rim 3 constitutes, with the cover 4, a central opening of the cable inlet and

  comprises to one side the opening 21 intended to receive and re-

  hold an insertion piece in the form of hook 22, constituted by deformation of the lower end of the cover 4 Similarly, the hook 23 is also formed by deformation of the same cover, fits into the slot 24 of the flange 3 so that, in combination with Parts 5 and 6 described above, the

  lid is held securely in place once the

  The orifice 25 receives the screw 27 which passes through the opening 26 pierced in the rim 3 of the device to be screwed into an orifice made in the housing of

  the device or machine on which the device is attached.

  Similarly, the orifice 28 pierced in the lower part 20 of the body 2 receives the screw 36 which is also screwed into an orifice

  pierced for this purpose in the housing of the device.

  The opening 30, the shape and dimensions of which are visible

  Figure 7, introduces the body 2 to the inte-

  the machine or machine, with the remaining edge 3 remaining

  TER AL. The plastic wire 31, integral with the body 2 and its cover 4, prevents the possible separation and the loss thereof. The cable 32 entering the device is folded according to a

  double bend, as shown in Figure 9, so that the ex-

  The ends of the conductors 33, once stripped, can be fixed to the terminals 7 by means of screws 8, as already described. To prevent their possible loss, the screws 34 clamped in the extensions 14 of the retaining bracket 13 are themselves retained by ribs 35 made on the inner walls.

  It goes without saying that many modifications can be made to the device described and represented without

depart from the scope of the invention.
