The present invention relates to an apparatus for coupling electrical components to a control or signaling device mounted in an opening in a plate in an electrical switchboard. The coupling device includes a tubular bushing member adapted to be secured in the opening and to receive a control or signaling device therein. Also. The coupling device comprises an apertured block in which the end of the tubular member can be fixed by elastic locking, which end extends towards the inside of the exchange during operation. The opening is used to mechanically or electrically connect a device mounted in the tubular member to a component that is secured to the block on the side away from the tubular member during operation.

The coupling device comprises a desk or casing, the switch being controlled by actuating a key or pressbutton or comprising signaling means using incandescent or semiconductor only or incandescent or semiconductor combined with a switch. Widely used when monitoring.

For example, US Pat. No. 4,451,720 describes a control device configured as described above, which uses a V-shaped spring clip coupled within a block to engage or support the control device. And an elastic device having two parallel arms disposed in a lateral notch at the end of the tubular member.

A comparable principle is also known from the Federal Republic of Germany Publication No. 26 09 473, which is used to mechanically lock two elastic hooks in which the laterally movable slide member is symmetrically operated. do.

To disassemble the device according to the above US patent specification (US PS), a spring loop is moved in one of two possible radial directions to deform the elastic arms using tools to disassemble them from the notches. Should be.

This device has the disadvantage that, if not taken care of, the associated elastic component can slip out of the recess during operation. If the recess is formed to prevent accidental detachment, the spring may become difficult to assemble. If it is desired to apply pressure on the elastic part in order to avoid the above-mentioned disadvantages, there is no stable pedestal of the tool used as a lever, which is quite difficult. In addition, the coupling force must be quite large in order to deform two elastic means simultaneously.

It is therefore an object of the present invention to synthesize blocks forming blocks to exhibit a snap-engagement effect without the need for components to double elastically deform the hook to be accidentally dislodged and assembled or disassembled. To provide a device comprising means for easily and quickly securing a block to a tubular member using the inherent elasticity of the material

For this purpose, according to the invention, for elastic locking purposes, the block has two hooks arranged on both sides of the end of the tubular member and cooperating with the matching shape above. The hook is secured relative to the block and is transverse to the axis of the tubular member when the second hook is operated by a tool extending into an eye formed in the protruding outer end of the sliding member away from the second hook. It is conveyed by the slide member which is completely connected to the block by the partition which can be elastically deformed so as to move the slide member.

In this way, one of the hooks is simply moved laterally by acting on a sliding member having a small hole into which it can easily enter, so it is freely released or engaged with the end of the tubular member in the opening of the block.

For example, other known control devices, such as those described in Federal Republic of Germany Patent Publication No. 2,801,074, extend through openings in the switchboard and are suitable for receiving a switching device fixed by elastic lateral means, It has a cylindrical component that cooperates with an elastic tongue integrated with an outer collar made of material. This tongue extends parallel to the axis of the tubular member and engages in a corresponding groove, but a nut is used to better cooperate between the groove and the tongue by fixing the tongue.

The invention also relates to a method for efficiently holding in place and a method for producing a block of synthetic material that is sufficiently rigid when in a relatively high stress state.

Hereinafter, with reference to the accompanying drawings will be described in detail the features and advantages of the present invention.

The accompanying drawings are only shown as an example, and the present invention is not limited thereto.

As shown in FIG. 1, the apparatus according to the invention comprises a tubular bushing member 51 comprising a neck 56 mounted in an opening 101 in a support plate 60. Outside of the plate 60, the bushing member 51 has a shoulder 102 on the outer surface of the plate 60 with an insert of a tag 103 and a seal 104. Widen into the collar 55. The threaded neck 56 externally cooperates with the nut 57 which presses the inner surface of the plate 60 and compresses the seal 104 with the collar facing the outer surface of the plate. A rotary control knob 106 used as an example of a control or signaling device is rotatably mounted in a bushing member in a known manner and remains stable during operation.

The end of the neck 56 away from the collar 55 is removably secured in the opening 5 extending through the block 1 to operate inside the switchboard.

The electrical component 107, for example one switch or one set of switches, is fixed to the surface of the block away from the tubular member 51. The means 108 for actuating the component are coupled in the opening 5 and are actuated by a cam 109 fixed to the knob 106. Thus, the knob 106 can be operated from the outside of the switchboard to actuate the switch 107 from the inside, the connection between the two parts being between the tubular member 51 and the opening 5 in the block 1. Is formed through.

The neck 56 (FIG. 2) is in combination with the corresponding protrusion 52 of the opening 5 in order to prevent the tubular member 51 from rotating about the block 1 around the axis XX 'of the tubular member. It has two notches 53 opposite to each other that are engaged.

The neck 56 has two skirts 54 between the two notches 53, and the block 43 on the neck 56 inside the skirt 54 is in contact with the collar 55 ( On the outer surface of the skirt each has a locking recess 44 which is adapted to cooperate by engaging with the locking means held by the block 1 when being pressed against the surface 42 of 1) (FIGS. 3 through 3). See also).

The means for locking the block 1 comprises two hooks 2, 14 which project radially toward the inside of the opening 5 from the periphery at oppositely opposed positions deviating by 90 ° from the position of the projection 52. do. These two hooks have a surface in contact with the collar 55 that moves away for snap-fit fitting.

The hook 2, ie the first hook, is almost secured to the remaining blocks. It is produced in one piece by molding plastic.

The second hook 14 (when in position) is connected to the rest of the block by three partitions 7, 8, 9 on a surface parallel to the opening 5 and the axis XX 'of the tubular member 51. Supported by the sliding member (6).

These three bulkheads can be elastically satisfied around an axis parallel to the axis XX ', so that the sliding member crosses the axis XX' and in the FO direction (FIG. 6) corresponding to the radial motion of the second hook 14. The protruding outer end 12 can be moved.

The partitions 7 and 9 are arranged on both sides of the sliding member protruding outer end 12 and connected to the vicinity of the hook 14. In non-operation, these partitions together form an obtuse angle extending radially towards the interior of the opening 5. The partition 8 is arranged on the same axis of the sliding member 6 as the partition 7 but further away from the axis XX 'close to the periphery of the bolus 1. The partition 8 is parallel to the partition 7 so as to cooperate with each other to form a deformable parallelogram between the sliding member protruding outer end 12 and the remaining block 1 to help guide the sliding member 6.

The partitions 7 and 9 extend the entire thickness H of the block measured parallel to the axis XX '. On the other hand, the partition wall 8 only extends to the portion h of this thickness, and the remaining thickness reinforces the transverse member 16, in particular to complete the shape of the transverse member as a rigid single piece frame. The cross-member 16, which is in contact with the two corner regions 17, 18 of the block, remains free.

Near the end of the transverse member away from the axis XX ', the sliding member forms a small hole 11 superimposed in the small hole 26 in the transverse member 16, but the partition 7-9 is non-parallel. The edge of the small hole 11 distant from the axis XX 'is slightly separated between the small holes 11 and 26 (FIG. 4) when it is operated or when the sliding member protruding outer end 12 is in the locked position. It is closer to the above-mentioned axis than this corresponding edge.

As shown in FIG. 7, the small holes 11 and 26 are suitable for receiving a tool 10, such as the tip of a driver. When the user rotates the screwdriver, one edge of the tool (the left edge in FIG. 7) is prevented from escaping in the axial direction XX by the small hole 26, and the other edge encloses the edge of the small hole 11 Press the slide edge 6 in the direction opposite to the axis X'X. Therefore, the user can move the slide member 6 by the lever effect using the driver 10 when the small hole 26 acts as a fulcrum for the lever.

As a result of the parallel slope having two opposite sides deformed by the partitions 7 and 8, the sliding member 6 moves almost parallel to its original position.

During this movement, the partitions 7-9 are bent and compressed. When the tubular member 51 is in place, the partitions 7-9 are kept under some residual compression and curvature.

As shown by the dashed-dotted line in FIG. 4, the area of the sliding member formed by the small hole 11 and the area of the transverse member 16 formed by the small hole 26 extend beyond the part 107, and the block The protrusions 12 and 29 are formed in relation to the rectangle in which (1) is inscribed.

On the side away from the sliding member 6, the block 1 has a groove 27 in the form of engaging with the projection. This makes the blocks in the switchboard very close together as shown in FIG.

The block 1 has a rectangular shape with a symmetrical long axis YY 'extending through the two hooks 2, 14, and the rectangular short axis ZZ' is a screw for increasing the rigidity of the block and fixing the part. It extends through two elements 22, 23 fitted in the block to bear the slicing holes 24, 25.

The tubular member 51 can be attached to the block 1 simply by force-fitting the tubular member into the opening 5 in the block.

For disassembly, the small holes 11 and 26 are engaged by the tip of the driver moving along the component 107 without removing the component 107. The lever effect is generated as described above, and at the same time the block 1 is relatively moved toward the block itself relative to the member 51.
