Description

DETAILED DESCRIPTION OF THE INVENTION The present invention comprises a substrate capable of housing at least one attachable air component, the orifice being specifically designed to co-operate in an intimate manner with an opposing orifice of an adjacent substrate. control module provided and associated with said substrate and an adjacent substrate to enable transfer of information and/or fluid supplies, said association being accomplished by a mechanical coupling device shaped to hold the substrates together; It is.

These modules are particularly useful when configuring automatic control systems, in which case they provide a continuous code, the associated modules must occupy a limited volume, and a metal cabinet is provided with mounting members such as metal parts. It is suitable when it is necessary to attach the

Substrates that can be combined are already known, such as French Patent No. 2154372 (71.35894) ``Elements for realizing functional pneumatic logic blocks with integrated circuits'' (
Daniel Boutil, filed September 29, 1971).

In this type of board, the connection is achieved by a tie bar extending across all the boards, the ends of which are threaded so that the clamping action can take place at the same time.

The drawbacks of this device are numerous.

The tie bars must be cut to the appropriate length according to the number of boards involved, which complicates shortening or expanding the chain and makes it impossible to remove it within the cabinet.

Second, when a board that is not located at the edge of the system must be changed, it must be completely disassembled.

Finally, the clamping device forming the coupling device may be lost and must be replaced by another member of the end of the chain connected to the feeding device, and one or more terminals of the last board of the chain may be removed. The orifice must be sealed with special equipment.

Other pneumatic control systems that can be associated with modules have side ears that must be connected by bolts to the preceding and following modules.

Assembly and disassembly of such systems is complicated;
The constitution required to set it in place is limited.

It is therefore an object of the present invention to provide a module having a substrate which is similar in function to that hitherto known, but which reduces the inconvenience of the known devices and allows quick assembly or disassembly of all or part of the device. The present invention provides a coupling device associated with each substrate, which coupling device also serves to seal the supply channel of at least the last substrate of the chain.

Another object of the present invention is to prevent the board from being disassembled when a freely attachable logic element is mounted on the board.

Finally, an interesting result aimed at by the invention is that by making the coupling device irremovable and by choosing the type of module-to-module tight coupling particularly suitable for the above-mentioned purpose, a complete guarantee of security and reliability is achieved. Provided is a module having a coupling system that provides.

According to the invention, each substrate is provided with a first housing shaped for accommodating a movable bonding device and a second housing capable of cooperating with a bonding device of an adjacent substrate, the bonding device being connected to two The coupling device assumes a first position at the extreme position, where the desired bonding with the adjacent substrate is achieved, and conversely the coupling device assumes a second position, where the bonding device achieves the desired bonding with the adjacent substrate. is configured to participate in sealing the orifice of the substrate without being associated with an adjacent substrate.

According to a preferred embodiment of the invention, the coupling device is located near the surface of the substrate shaped to accommodate the attachable element, so that when the attachable element is placed in position, a portion of said element is Locking of the coupling device is provided in the first and second positions.

Other useful configuration examples can be understood from the description of the drawings below.

These implementations are not intended to limit the invention.

As shown diagrammatically in FIG. 1, a single-piece air module 1 is interconnected with adjacent modules 1'.

For simplicity, only one channel 50 and 5σ each is shown.

The connection is intended in principle to allow fluid to pass from the channel 50 to the subsequent channel 5σ.

Both modules are brought into association and their opposing sides are crimped to the sealer tube indicated by the rOJ ring seal 51.

on one of the module 10 faces 53) mountings 2 and 4;
and 71 housings 2 and 1 are provided in the adjacent module 1', which housings are adapted to accommodate in each case a part of the movable coupling device 3, which is considered to perform a dual function.

Firstly, place the coupling device 3 on the first device a and arrow F1
When driven in the direction of , this causes the adjacent module 1
and 1' to achieve the connection so that a sealant tube can be used.

In this position the coupling device 3 enters the housings 2 and 4 and ensures the mechanical connection of the modules.

Each module is distributed to a customer, in which case the coupling device 3 is placed in the housing 2 and the coupling device 3 is applied to the housing 2, for example by friction or elasticity.

Then the same coupling device 3 or preferably module 1'
Place the coupling device distributed with the arrow F2
The second function of the coupling device is achieved by driving in the direction of .

The coupling device cooperates with the sealer tube 51' to connect the channel 5σ.
The orifice σ will be sealed.

In the row shown in FIG. 2, the air module 100 and its associated adjacent module 10σ are each configured with a substrate 1, on which the air component 5, which can be mounted, is
For example, it is fixed with a mounting screw 52.

This embodiment is preferred where it is desired that the substrate serve as a collection of fluid transfer and/or pneumatic signal carrying piping, and the attachable elements may be used to solve logic equations or achieve time lag, locking, etc. is assigned to.

In this last case, the attachable air component 5 comes into contact on the surface 80 of the substrate, with its part 31 being located opposite the coupling device 3 .

Once the coupling device 3 is placed in the correct position, it is sealed by the presence of the element 5.

FIG. 3 shows the construction of the locking device as shown in the above drawings.

In principle, the device newly designated by reference numeral 3 consists of a rotating body consisting of an upper part 7, the ends of which are folded to form an ashtray-like part 8, with a cylindrical extension projecting in the center. 12 is placed.

The housings 2 and l are each shaped to accommodate a half of the coupling device in position a, and are therefore provided with annular portions 11 and 11', and furthermore are continuous with grooves 9 and 1 designed to accommodate said cylindrical extensions. shall be established.

The locking device frictionally or elastically joins both housing halves together and utilizes the same phenomenon to maintain the device in position.

In the latter case, the locking device acts as a plug 82 in cooperation with a tight container 51' which is permanently arranged in the module 1'.

In the variant shown in FIG. 4, the coupling device is constructed with a lever 13, which is connected to the
3 by a shaft 33, and this upper portion 53 is configured to face a surface 54 and serve to fix the substrate 1 to the holder.

Each board is provided with two housings 2 and 4 and 2 and a, respectively.

1) The housing 2 accommodates a shaft 33 in its upper part,
further extending through passage 110 (and 1σ);
The lever 13 can be accommodated in this passage when placed in the second position.

The second housing 4 and a have first notches 15 and 15', respectively, which engage a hook 14 provided on the lever 13 when the lever 13 is placed in the first device a, and thus to achieve the bonding of two adjacent substrates or modules.

In addition to the hook 14, the levers 13 and 13' have cylindrical or conical projections 17 and 1γ, which are located opposite the orifices 6 and σ of the base plate and provide a seal therewith.

The seal is maintained by hooks 14 and 14' and passages 10 and 1.
This is ensured by the respective cooperation of the second notch 16 and 1da adjacent to 0'.

This type of substrate is very easy to implement when the substrate accommodates an attachable air element as shown in FIG.

When realizing the above embodiment, the coupling device is arranged on the upper side of the module or even near the wall, which is perpendicular to the module.

Even in the latter case, the freely mounted air element can be adapted to obtain the locking effect as described above.

However, the fact that two adjacent modules or substrates are joined near the upper or orthogonal planes results in the disadvantage of a lack of chain rigidity caused by the juxtaposition of a large number of modules.

This can be tolerated if the substrate or module is fixed at an arbitrary position on the holder.

The holder is, for example, a rail with a certain cross-section, onto which the lower surface is firmly hooked by means of an elastic tie-down having a certain rigidity.

In order to improve the rigidity of the chain of associated modules or substrates, it is desirable to bond them along their sides or side walls.

Two rows of such connections are shown in FIGS. 5 and 6.

FIG. 5 shows two mutually opposite sides 3 of module 1.
4 and 29 are provided with two housings 27 and 28, respectively.

The coupling device is constructed with a sliding drawer 18 which can be moved between two positions C and d along the housing by moving the drawer 18 in opposite directions.

As is well known, sliding joint members 19 and 19' are formed by connecting mutually overlapping parts.
can be obtained by

Therefore, the drawer 18 is arranged to overlap between two adjacent substrates 1 and 1, and the first surface 20 is
contacting the bottom of the housing 27 of the substrate and
A second surface opposite the surface is brought into contact with the housing 28 of the adjacent board and the bottom of the second girdling.

Drawer 18 is placed in module 1 and the modules are already connected.

In addition to the sliding member 19, two hooks 22 and 23 can be provided on the second side of the drawer 18, which can be connected to two bolts 24 located near the housing 28' of the adjacent board.
Let them work together.

The role of these hooks is to obtain a locking effect when the drawer 18 is placed in position d, or to serve more effectively for the connection near the orifice 6, C, or to perform these two functions.

In addition to the sliding device described above, the drawer 18 can also hold a device indicated at 34, which cooperates with it to hold in place a plug 45 designed to seal the orifice 6.

A plug 45, which is an inexpensive component, can be provided with the module or separately.

In this case as well, the drawer performs two functions.

On the one hand, the drawer connects adjacent modules or substrates, and on the other hand it serves for the sealing of one orifice.

The performance of these two functions cannot be distinguished by the two sensually distinct positions of the drawer.

In this case too, the face 30 of the base plate accommodates a attachable air element, which ultimately locks the drawer in the operating position.

5 and 6 show how the drawer cooperates with the annular groove 41 of the plug 45 to form a locking by the semicircular collar 40. FIG.

The drawer, when placed, is associated with the module or with the board and can be designed to be non-removable, but this differs from the case in the embodiments described above.

To prevent the drawer from being removed (resulting in limiting the range of the substrate to which the drawer is fixed).

It is therefore essential to adapt the part of the bonding device that cooperates with the adjacent substrate to satisfy limited movement conditions that allow bonding and unbonding operations.

First, the column that makes the drawer non-removable will be described with reference to FIG.

As a general rule, the drawer 35 has two dovetail slots 25 and 2.
The shape of a flat prism is formed by joining 6 along its minimum base.

The first and second housings 27 and 28 each have a complementary dovetail shape corresponding to the grooves.

The movement of the drawer 35 is limited on the one hand in direction d by a predetermined thrust 42 which is integral with the drawer and is placed in a cavity 43 of the base plate.

On the other hand, a hook 38 integral with the bottom of the drawer will be located facing a notch 39 in the base plate, and its length will be such that it will provide a certain amount of linear movement to the drawer.

The hook 38 exhibits sufficient elasticity to allow its positioning to be effected by deflection of the material.

As in the previous drawing, the drawer 35 has a semicircular collar 40.
, which cooperates with the ring-shaped groove 41 of the plug 45.

Notches 36 and 37 are cut into the edge of the second slot 26 of the drawer, and two areas 48 and 49 are similarly cut into the edge of the dovetail cutout of the adjacent module.

These various notches are the tenon parts 22, 23° 46.4
7 and the chest portions 55, 56 remain, which face each other when the drawer is driven to position d, and conversely, when the drawer is placed in position C, the said parts of the tenon and chest are located opposite the notch. It is thus possible to press two adjacent substrates together along their side walls 29 and 34'.

When the drawer is driven with the substrates juxtaposed, the portions of the grooves and ribs are embedded and the desired mechanical connection is achieved.

These parts make it possible to achieve a bond that is distributed over the entire height of the substrate, thus improving the rigidity of the mounting.

Figure 7 shows the orifice 6 and σ in the embodiments of Figures 1 to 6.
In other words, a tight coupling device suitable for easily solving coupling constraints is shown.

This coupling device has a passage 10 in the module 1 located in the vicinity of the housing 27, a trick fitting 51 designed to cooperate with the protruding tip of a tube 60, usually made of flexible plastic material, The other tip 63 of 60 is held in place by a clamp 61 extending transversely to the adjacent module 1'.

Said clamp 61 exhibits a conical profile and comes into contact with the conical housing 62 of the module 1', thereby providing a permanent retention and quick anchoring of the tube.

FIG. 8 shows the structure of a device utilizing the principle of the coupling device of FIG. 6 and the module of FIG. 2.

The entire board is fixed to the metal part 2 and several air elements 3
Install.

The flexible pipe 14 is connected to a quick coupling device 15 as shown in FIG.
There are also devices for supplying fluid through the .

In the unattached position of the air element, a driven coupling drawer is seen at 29a, whereas drawer 29b is in a partially tensioned state to allow separation of adjacent substrates 1', and the coupling flexible tube 22 is This shows that the tip can be easily separated.
