Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a device for connecting electrical components to control or signaling devices mounted in openings in the plates of switchboards.

The device comprises tubular bushing means adapted to receive and secure within the opening a control or signal device. The device also comprises a block in which an opening is formed, in which the end of the tubular means is secured by an elastic lock, the end projecting towards the inside of the switchboard during operation. There is. The opening is used to mechanically and/or electrically connect a control or signaling device mounted within the tubular means to an electrical element, said electrical element being connected to the block during operation. , secured on the side remote from the tubular means.

This noble device is intended for use in monitor desks or monitor casings which control switches by activation of keys or pushbuttons, or which are equipped with incandescent or semiconductor signaling means, either alone or in combination with switches. is widely used.

[PRIOR ART AND PROBLEM TO BE SOLVED BY THE INVENTION] For example, U.S. Pat. A control device is disclosed having two parallel arms disposed in transverse cutouts at the ends of the member, by which the device is adapted to grip and hold.

A similar principle is also known from German publication DEB 2609473, in which a transversely moving slide is used to mechanically lock two mutually symmetrically acting elastic hooks. .

To remove the U.S. patent device, use a tool.
Loop the spring in one of two possible radial directions.
direction, the elastic arm must be deformed, and the arm must be removed from the notch.

This device requires the elastic elements to be connected;
It has the disadvantage that it will fall out of the recess if care is not taken during operation. If the recess were to be shaped to prevent such accidental falling off, it would be difficult to install the spring.

If one were to try to apply pressure to the elastic element in order to avoid the aforementioned disadvantages, it would be very difficult, since there is no stable fulcrum to use the tool as a lever.

Furthermore, the force required to fit or engage must be relatively large in order to deform the two elastic means simultaneously.

Therefore, the object of the present invention is to form a block in order to exert a snap effect, without any elements that can cause accidental falling off, and without requiring elastic deformation of double hooks for installation and removal. It is an object of the present invention to provide a device equipped with means for easily and quickly attaching a block to a tubular means by utilizing the natural elasticity of a synthetic resin material.

[Means to solve the problem]

To this end, according to the invention, for the purpose of elastic locking, the block has two hooks corresponding to each side of the end of the tubular means and adapted to engage by means of mutually adapted shapes. in which case the first hook is fixed with respect to the block, while the second hook is supported by a slide integrated and connected to the block by a septum, said septum being elastically deformable; The slide thereby became detached from the second hook of the slide.
Movement transverse to the axis of the tubular means is possible by action of a tool extending into an eyelet formed in the outer end of the projection.

In this way, one hook is easily moved aside by the movement of the slide, which has an easily accessible eyelet, and is thus free to leave the end of the tubular means that is within the opening of the fooro vine. Or engage.

Other known control devices, for example, the device disclosed by German Patent Application No. 2801074, comprises a cylindrical element extending through an opening in a switch board and adapted to receive a switch device. ,
The switch device is held in its position by means of resilient lateral acting means and a resilient tongue acting integrally with an external collar made of synthetic resin material. Said tongue extends parallel to the axis of the tubular means and engages a corresponding recess, which must be tightened using a nand to ensure a secure connection between the recess and the tongue.

The invention also relates to a process for effectively holding the block in place and to making the block from a synthetic resin material of sufficient stiffness when subjected to relatively high stresses.

Other features and advantages of the invention will become apparent from the description provided below.

〔Example〕

As shown in FIG. 1, the device according to the invention includes a tubular bushing member 51 including a neck 56 attached to the aperture 101 of the bearing plate 60. As shown in FIG. On the outside of the plate 6o, the bushing 51 expands to form a collar 55, which is connected to the shoulder 1.
02, and the shoulder rests on the outer surface of plate 60 with tongue 103 and seal 104 in between. Externally threaded neck 56 engages a nut 57 that receives the inner surface of plate 60, tightening the collar toward the outer surface of the plate and compressing seal 104. Rotary control knob 106, taken as an example of control and/or signaling means, is rotatably mounted in a known manner within a bushing that is held stationary during operation.

The end of the neck 56 that is far from the collar 55 is
It is removably mounted and retained in an opening 5 through the block 1 and thus operates inside the switchboard.

An electrical element 107, such as a switch or a set of switches, is held on the surface of the block, remote from the tubular member 51. Means 108 for activating the electrical element include a cam 10 that fits into the aperture 5 and is attached to the knob 106.
Operated by 9. Thereby, the knob 106
From the outside of the switch board, switch 107 on the inside
, in which case the connection between the two takes place through the tubular element 51 and the opening 5 in the block 1.

The neck 56 (FIG. 2) has diametrically opposed notches 53.
, the notch engages a corresponding projection 52 of the opening 5 when assembled and prevents rotation of the tubular member 51 with respect to the block 1 about the axis Xx' of the tubular member. ing.

The neck 56 has 1. two skirts 54 between the two notches 530, each of the skirts having a locking recess 44 on its outer surface, and the inner part of the skirt at the shoulder 43 of the neck 56 having a collar 55. The top surface 42 of block 1 faces
It is adapted to compliantly join the locking means by the block l when pressed against it. (Figures 1 to 3)
The means for locking the block 1 is 9 from the position of the protrusion 52.
It is constituted by two hooks 2, 14 which are offset by 0" and are diametrically opposed and project radially from the circumference of the opening 5 towards the inside of the opening.

The two hooks have surfaces facing the collar 55 and move apart for the purpose of snap-lock attachment.

Hook 2, the first hook, is held substantially rigidly on the rest of the block. The hook 2 is made of molded synthetic resin integrally with the rest.

The second hook 14 consists of three septums with planes parallel to the axis XX' of the opening 5 and the tubular element 51 (if in its position). , 8.9 by a slide 6 connected to the rest of the block.

The three bulkheads can be bent to wrap around the axis parallel to the axis XX', so that the slide has the ability to move in the direction F, 0 transverse to the axis XX', and the second This corresponds to the radial movement of the hook 14.

The bulkheads 7.9 are located on both sides of the slide 12 and have hooks 1
It is connected to four neighbors. When not in operation, the partitions together form an obtuse angle extending radially inside the opening 5. The bulkhead 8 is on the same side of the slide 6 as the bulkhead 7, but further away from the axis XX' and near the periphery of the block 1. The bulkhead 8 is parallel to the bulkhead 7 and forms a deformable parallelogram between the slide 12 and the rest of the block 1;
Thus, it helps guide slide 6.

The partition walls 7, 9 have a height corresponding to the total thickness (H) of the block, measured parallel to the axis XX'. On the other hand, the partition wall 8 is
It has only a height (h) equal to part of this thickness, the remainder of the thickness being devoted to the cross members 16 connecting the two corners of the block between the areas 17, 18, which strengthen the block and
More specifically, its shape is that of a solid, integrated frame.

Near the end remote from the axis XX', the slide is formed with an eyelet 11 which overlaps the eyelet 26 in the cross member 16, but the bulkheads 7-9 are not in operation or the slide 12 is in the locked position, small holes 11 and 2
6 has a slight deviation (Fig. 4), so that the small hole 11 on the side farther from the axis xX'
The edges of the eyelet 26 are closer to said axis than the corresponding edges of the eyelet 26.

As shown in FIG. 7, the eyelets 11 and 26 are adapted to receive a tool 10, such as the tip of a screwdriver. When the user turns the screwdriver, one edge of the tool (left edge in FIG. 7) is prevented from escaping in the axis XX' direction by the small hole 26, while the other edge is prevented from escaping in the direction of the axis XX' by the small hole 11. press the corner of and move the slide 6 in the opposite direction of axis XX'.

In this way, the user can use the screwdriver to move the valve 6 by means of a lever effect, with the eyelet 26 acting as a fulcrum for the lever.

As a result of the action of the parallelogram with opposite sides formed by the partitions 7 and 8, the slide 6 moves almost parallel to its home position.

During this movement, the partition walls 7-9 bend and become compressed. When the tubular element 51 is in position, the partition walls 7-9 are
It remains under slight residual compression and is bent.

4, the area of the slide in which the eyelet 11 is formed and the transverse member 1 in which the eyelet 26 is formed.
The area 6 extends beyond the electrical element 107 and forms protrusions 12 and 29 with respect to the rectangle in which the block 1 is anyway inscribed.

On the side remote from the slide 6, the block l has a recess 27 with a shape adapted to the projection. This allows the blocks to be packed very closely together within the switchboard, as shown in FIG.

Block 1 has a rectangular shape, and its long axis of symmetry XX' is 2
The short axis ZZ' of the rectangular shape extends through two hooks 2, 14, while the short axis ZZ' of the rectangular shape is substantially mounted within the block to enhance the rigidity of the block, and also includes a threaded hole 24 for retaining components. Two elements 22, 2 with °25
Extends through 3.

The tubular means 51 can be attached to the block 1 simply by pushing it into the opening 5 of the block 1.

Removal can be accomplished without removing the electrical element 107 by placing the tip of a screwdriver in the small holes 11 and 26 and moving it along the electrical element 107. As mentioned above, a lever effect occurs and the block 1 separates from the member 55 at the same time.
