  The present invention relates to the design and production of a support frame for the components of the pain

  locking electrical connection.

  Locking electrical connection sockets are electrical distribution devices that can be mounted on walls or installed on support panels. A locking electrical connection socket essentially consists of a switch, optional protective devices and an industrial socket (in accordance with European standard EN 60309) and in which it is characterized in that it includes a locking mechanism. . Thanks to this locking mechanism, a male plug can only be inserted or removed when the switch is in the open position and the switch can only be put in the closed position if the male plug is inserted in the socket. Said locking electrical connection sockets have a protective housing which normally consists of a base housing and a cover. The various components (socket, switch, protection device, etc.) are generally mounted using the base housing or the inside of the cover directly as a support and are connected to each other at the

by means of electric cables.

  This entails drawbacks due to a certain difficulty in placing the cables for the connection of the electrical system because of the lack of space available around

of the different components.

  The locking bushings are mounted both in versions comprising a housing made of insulating material and in versions comprising a housing made of metallic material. Therefore, it is necessary to keep both versions in stock, which incurs an expense

excessive in matter and space.

  locking according to the invention is described with the aid of the figures.

  FIG. 1 represents a locking socket designated as a whole by the reference numeral 100. The locking socket 100 comprises an external housing and a group of electrical components 4 which must be enclosed inside the external housing. Component group 4 is mounted on a frame

  support 5 of substantially rectangular shape.

  The outer case includes a base case 2 of parallelepiped shape and a cover 3 which can be mounted on the base case 2 so as to enclose therein the group of components 4 which are mounted on the support frame 5. The base case 2 and the cover 3 are generally made of an insulating plastic material or a metallic material such as aluminum, for example

example.

  s As also shown in FIGS. 2, 4 and 5, the group of components 4 comprises a switch 6 which is mounted on the rear part of the support frame 5, a fuse block 7 which is mounted in the central part of the frame support 5, a socket 8 which is mounted in the front part of the support frame 5 and a locking mechanism 23 which is mounted in the front part

of the support frame 5.

  The switch 6 has the shape of a parallelepiped box which comprises, in its two lateral faces, tongues 11 which

  are projecting and which are intended for assembly on the frame 5.

  In the rear face of the switch 6, there are holes or housings 12 provided with electrical contacts for receiving the strands of the electric power cables. On the upper face of the switch 6 is a hole 13 intended to receive a coupling pin 10 which

has a notched head.

  n / a Two lateral shoulders 14 rise upwards from the rear part of the support frame 5. The inside face of the shoulders 14 engages with the projecting parts 11 of the switch 6. Fixing means 24 of the screw type can

  be provided for fixing one of the projecting lateral tabs 11 of the switch 6 on the support frame 5 while the other lateral tab is placed in a housing provided in

the lateral shoulder considered.

  s In the central part of the frame 5, a cross member is provided which supports the fuse block 7. The fuse block 7 has the shape of a parallelepiped box in the upper face of which three bases 16 have been formed in which are

  mounted three small plugs 17 for receiving fuses.

  o A pin 18 rises upwards from the front face of the support frame 5. The pin 18 comprises a substantially circular flange 19 on which the substantially cylindrical sleeve 8 is mounted. The sleeve 8 comprises, in its front face, holes 21 intended to receive the poles of a socket

  A support 22 projects forward from the frame 5 below the flange 19. The support 22 receives the

lock 23.

  A cam 20 comprising a coupling pin 25 which penetrates inside the switch 6 is mounted below the support frame 5 in the direction of the switch 6. The cam 20 comprises a cam path 26 which receives a cam follower 27 which is mounted on a locking lever 28. The locking lever 28 comprises, in a central position, a flange 29 which is pivotally mounted in the bottom wall of the support frame 5. The locking lever 28 has, at its end opposite the cam follower 27, a fork 50 which operates the locking mechanism 23. The support frame 5 comprises, in its front part, a pair of opposite pins 30 which project laterally. The pins 30 are designed to engage in corresponding grooves 31 which are arranged on the inner face of the

  side walls of the base case 2.

  Once the support frame 5, on which the group of components 4 has been mounted, is put in place in the base box 2, to connect the electrical supply cables, the operator can lift the rear part of the support frame 5 which rotates around the axis of the pins 21 in such a way that the housings 12 of the switch 6 are raised relative to the rear part of the

basic case 2.

  The rear wall of the base housing 2 has a through hole 32 which allows the passage of a sheath 33 which surrounds a group of electric power cables 34. In this way, the strands of the electric cables can be inserted and fixed. supply 34 in the housings 12 of the switch 6 and, once this operation is completed, the rear part of the support frame is lowered in such a way that the frame is perfectly in place at

Inside the base case 2.

  At this time, the cover 3 can be mounted on the base housing 2. The support frame 5 is held in the correct position without having to use screws thanks to the positioning parts of the frame which come to rest on the cover 3. As is o shown in Figure 3, a seal 35 is interposed between the base housing 2 and the cover 3. The cover 3 has a substantially cylindrical hollow portion 36 which projects forward from the latter. The cylindrical part 36 of the cover 3 is designed to receive the socket 8 and is covered by a

  plug 38 which is hinged therein (see FIG. 1).

  In the rear part of the cover 3, a cylindrical flange 39 is provided which is designed to receive a button 40 which can be actuated by the operator to put the switch in the open or closed position. The button 40 includes a locking device 41 which engages with the head 10 of the switch 6 to operate it. A seal 42 is interposed between the

button 40 and flange 39.

  There is provided, in the upper central part of the cover 3, a square flange 43 which allows accessibility to the poles 17 of the RA07-08B.DOG i
