System for mechanical and electrical connection between electronic devices to be integrated into flush-mounted electrical equipment items

This invention relates to a system for mechanical and electrical connection between generic electronic communication devices and electronic devices of specific function which are to be integrated into flush-mounted electrical equipment items for domestic use.

The increasing evolution of electronic communication systems using bus communication lines (along which digital signals corresponding to information and data are transferred) presents to an increasingly serious degree the problem of connecting and integrating electronic devices of specific function (for example thermostats, programmers, electronic control units, small electronic processors) into the system.

Said electronic devices are currently formed in a single container containing both the elements for supporting communication between the device and digital bus (access doors, communication control, control unit), and the electronic circuit which implements the specific function, or alternatively in physically separate containers connected by connection cables (in this case the specific functions requested and the communication process cannot be mutually coordinated).

If reference is made to domestic electronic devices for flush-mounting, the problem is even more evident because known devices are generally of single-block type.

They direct the specific electronic function or consist of communication gates of generic type and hence, as such, cannot be coordinated with the modular lines of flush-mounted equipment items, either in terms of homogeneity between bus communication and specific electronic function, or in terms of integration with said flush-mounted modular lines.

This gives rise to the drawback of not being able to propose and separately install a specific electronic circuit and generic electronic communication devices.

Moreover, if the electronic part relative to bus communication is physically separate from that specific function, said communication part cannot be used as a network addressable unit of generic connector type integrated into the modular lines of flush-mounted electrical equipment items for domestic use.

Finally, for the aforesaid reasons it is not possible to use a single electronic part reserved for bus communication or an assembly of different functional modules housed in the same flush-mounting box.

An object of the present invention is therefore to indicate a system for mechanical and electrical connection between electronic devices to be integrated into flush-mounted electrical equipment items for domestic use, which obviates the aforesaid drawbacks, by allowing wide freedom of installation of the functional electronic and communication parts (joint or separate installation, further connections to electronic equipment items for the simultaneous use of several coupled devices, possibility of network addressing).

A further object of the present invention is to provide a system for mechanical and electrical connection between electronic devices to be integrated into flush-mounted electrical equipment items for domestic use using standard circuit techniques, unique mechanical and electrical arrangements, and aesthetically rational and elegant configurations.

A further object of the invention is to provide a system for mechanical and electrical connection between electronic devices which is of simple and low-cost construction, without the use of complex or costly techniques.

These and further objects are attained by a system for mechanical and electrical connection between electronic devices to be integrated into flush-mounted electrical equipment items for domestic use in accordance with claim 1.

Advantageously, the system for mechanical and electrical connection between electronic devices according to the present invention comprises a plate for flush-mounted electrical equipment items for domestic use (mounted by means of the usual accessories defined for this), comprising a communication module (mechanically compatible with the modular lines of the plate), which presents a series of connectors for data transfer and for powering, which can be used for trailing-cable connection to semifixed external equipment items, in a like manner to the connection of a telephone to a flush-mounted socket.

A trailing plug, designed to engage the socket of the communication module, is connected by connection cables to other electronic equipment items, by plugs which are also harmonized into a unique mechanical and aesthetic arrangement.

A series of electronic equipment items implementing different specific functions and characterised by a container provided with a connector are coupled rigidly and ergonomically to the socket provided in the communication module, and occupy the recess in the communication module.

The communication module and the electronic circuit of the equipment items which implement specific functions are housed in separate containers, although harmonized into a unique mechanical and aesthetic arrangement, allowing the widest installational freedom.

Moreover the communication module is also usable as a network addressable unit provided with a rigid and ergonomic socket for connection by cable to electronic equipment items external to the system.

Finally, a single communication module can present to the user a plurality of sockets, allowing the simultaneous use of several coupled electronic devices or of several plugs or a combination thereof, so as to distribute the cost of the communication circuits among several users.

Further objects and advantages of the present invention will be apparent from the ensuing description and the accompanying drawings, which are provided by way of non-limiting example and in which: <ul id="ul0001" list-style="none" compact="compact"><li>Figure 1 is an exploded schematic view of the mechanical and electrical connection system of the present invention;</li><li>Figure 2 is a schematic front view of the plate of a mechanical and electrical connection system, provided with a double data and power socket compared with the system of Figure 1;</li><li>Figure 3 shows an electronic device for transferring information and data, which is housed within the plate of the mechanical and electrical connection system;</li><li>Figure 4 represents a plug connected to the electronic device of Figure 3;</li><li>Figure 5 shows an electronic equipment item of specific function connected to the electronic device of Figure 3.</li></ul>

In Figures 1 and 2, the reference numerals 10, 10A indicate a flush-mounting plate housing a flush-mounted electrical equipment item 30, 30A and one or more series-connected electronic devices 20, 20A, 20B able to transfer information and data along digital communication buses.

The electronic devices 20, 20A, 20B are provided with sockets 80, 80A, 80B for data transfer and powering. Said sockets 80, 80A, 80B can be connected to plugs 40 provided with cable 90 for connection to other electronic equipment items (not shown), or can house electronic devices 50 of specific function.

In Figures 3, 4 and 5, the reference numerals 20C, 20D, 20E indicate three electronic devices arranged to transfer information and data along digital communication buses 60, 60A, 60B.

Connection between each electronic device 20C, 20D, 20E and each bus 60, 60A, 60B is obtained by the connectors 80D, 80E, 80F respectively.

The reference numeral 80C indicates a data transfer and powering socket, 40A indicates a plug provided with connection cable 90A for connection to other electronic equipment items, and 50A indicates an electronic device of specific function.

The connection system of the present invention provides the facility for inserting, into flush-mounted electrical equipment items 30, 30A for domestic use (generally of modular type), plugs 40, 40A for connecting electronic equipment items external to the system (by connection cables 90, 90A) and/or electronic devices 50, 50A of specific function.

This connection enables information and data to be transferred from the electronic equipment items external to the system or from the electronic devices 50, 50A of specific function, to the communication buses 60, 60A, 60B via the electronic devices 20, 20A, 20B, 20C, 20D, 20E (inserted in a variable number into the plates 10, 10A of the flush-mounted electrical equipment items 30, 30A for domestic use).

This is made possible by the connection between the sockets 80, 80A, 80B, 80C and the plugs 40, 40A and/or electronic devices 50, 50A.

The characteristics of the system for mechanical and electrical connection between electronic devices to be integrated into flush-mounted electrical equipment items for domestic use according to the present invention are apparent from the aforegoing description, as are its advantages.
