Definitions
- the present invention relates to a terminal board, preferably of the N-terminal (multi pole) type, having modular contacts. Terminal boards of this type are particularly useful for making the electric connections required for powering air conditioning apparatuses.
- 'terminal boards' which consist of an electrically non-conducting body, to which a plurality of electric contacts, possibly interconnected, are mounted.
- the most used contacts are screw terminals, generally consisting of a threaded nut or matrix engaged by a fastening screw for a stripped end of an electric wire, or of faston-type reed contacts.
- Spring contacts are also used, e.g. of the type illustrated in JP-A-6333632 , inorder to make quick connections, particularly on wires having stripped ends or preferably, on wires butted by means of a rigid tip, or by tinplating.
- the known terminal boards of the aforesaid type are not, however, able to simultaneously / indifferently make connections of different type, so as, for example, to be able to use the same terminal board, both for making connections which require contacts consisting of screw terminals, and for connections using spring contacts. If contacts of both types were installed on the same terminal board, the interconnections between the contacts would need to be doubled, with consequent additional costs, an excessively complex layout of the terminal board and, above all, a large bulk, which is not acceptable in the field of electric household appliances, where the spaces available for this type of devices are always smaller.
- a terminal board is thus provided as defined in claim 1.

Description
- The present invention relates to a terminal board, preferably of the N-terminal (multi pole) type, having modular contacts. Terminal boards of this type are particularly useful for making the electric connections required for powering air conditioning apparatuses.
- As known, the electric connections required for electrically powering an electric household appliance are made using wiring devices known as 'terminal boards', which consist of an electrically non-conducting body, to which a plurality of electric contacts, possibly interconnected, are mounted. The most used contacts are screw terminals, generally consisting of a threaded nut or matrix engaged by a fastening screw for a stripped end of an electric wire, or of faston-type reed contacts.
- Spring contacts are also used, e.g. of the type illustrated in
JP-A-6333632 - The known terminal boards of the aforesaid type are not, however, able to simultaneously / indifferently make connections of different type, so as, for example, to be able to use the same terminal board, both for making connections which require contacts consisting of screw terminals, and for connections using spring contacts. If contacts of both types were installed on the same terminal board, the interconnections between the contacts would need to be doubled, with consequent additional costs, an excessively complex layout of the terminal board and, above all, a large bulk, which is not acceptable in the field of electric household appliances, where the spaces available for this type of devices are always smaller.
- Therefore, it is an object of the present invention to provide a terminal board with modular contacts which, though having a small bulk and preserving a simple layout and, accordingly, having low production costs and high assembly ease, allows to indifferently make connections of at least two different types on the same terminal board.
- According to the present invention, a terminal board is thus provided as defined in claim 1.
- Specifically, the terminal board comprises a body made of an electrically non-conducting material delimited between a first and a second opposite longitudinal faces making connections which require contacts consisting of screw terminals, and for connections using spring contacts. If contacts of both types were installed on the same terminal board, the interconnections between the contacts would need to be doubled, with consequent additional costs, an excessively complex layout of the terminal board and, above all, a large bulk, which is not acceptable in the field of electric household appliances, where the spaces available for this type of devices are always smaller.

- A terminal board according to any one of the preceding claims, characterized in that the terminal board further comprising an additional element (101) comprising a standard pin terminal board consisting of a plurality of insulating body portions obtained in one piece reciprocally side-by-side and held together by bridge-shaped body elements which may possibly, easily be cut, each of which provided with a pair of screw terminals (105), of which one is adapted to transversally receive an end of an electric wire and the other withholds a fork-shaped oval tip cylindrical pin (106); the distance between said bands (100) of said bridge elements (18) and the size of the third holes (47) being chosen so that said pins (106) are in use freely insertable into the third holes (47) inserting the fork-shaped oval tips thereof into the void between each pair of said bands (100) placed side-by-side, which is slightly smaller in size than the diameter of the pins (106), thus elastically deforming the latter.
