Definitions

  • the present invention generally refers to the field of electrical connections, and in particular regards a quick insulation displacement connection device (IDC) for electrical connections.
  • IDC quick insulation displacement connection device
  • the function of the device according to the invention is that of drawing the electrical signal from a bus formed by a pair of conductors (twisted together or parallel), by means of the insulation displacement connection (IDC) principle.
  • IDC insulation displacement connection
  • the quick insulation displacement connection devices substantially provide for the use of pairs of contact blades, in which each blade pair is housed inside a respective contact-carrier element of an electrical line.
  • connection terminal of a respective electric cable is inserted in order to draw its signal to be sent over a shunt electrical line.
  • the electrical contact is usually made by means of a pressure system, i.e. by pressing each electrical cable, equipped with related outer insulation sheath and respective inner conductor, between the blades of the contact-carrier element, such that the cutting edges of the blades remove the insulation sheath of the electrical cable from the inner conductor and contact the aforesaid conductor, establishing the desired electrical connection between the terminals.
  • a pressure system i.e. by pressing each electrical cable, equipped with related outer insulation sheath and respective inner conductor, between the blades of the contact-carrier element, such that the cutting edges of the blades remove the insulation sheath of the electrical cable from the inner conductor and contact the aforesaid conductor, establishing the desired electrical connection between the terminals.
  • the terminations of the electrical conductors can be simply joined together, without having to previously remove insulation sheath pieces of the electrical cable, in order to free the inner conductor.
  • the insulation displacement connectors can also be arranged in series within a single connection interface, so to make several electrical connections between respective cable terminations in a single operation.
  • the known electrical connection devices of IDC type still lack of flexibility of use, above all if it is necessary to draw the electrical signal from a pair of conductors (twisted or parallel) positioned inside suitable housing raceways; this is typical of the buses for the transport of the electrical signal and/or electrical line made with twisted wire and equipped with ceramic insulators.
  • the object of the present invention is that of overcoming the mentioned drawbacks, and in particular that of making a quick insulation displacement connection device for electrical connections which allows making, in a simple, quick and practical manner, the electrical terminations of the cables to be connected and in particular the pick-up of the bus signal housed inside a raceway.
  • Another object of the present invention is that of making a quick insulation displacement connection device for electrical connections which allows attaining considerable installation and wiring ease and speed and functionality of the connection, as well as effective installation arrangement for any technical installer, even one not particularly specialised.
  • Another object of the present invention is that of making a quick insulation displacement connection device for electrical connections which is extremely simple and quick to install and to wire.
  • Further object of the present invention is that of making a quick insulation displacement connection device for electrical connections which is easy and inexpensive to make.
  • the quick connection device is entirely integrated in the electrical and/or home automation systems, and allows making electrical connections on lines and/or buses in an advanced, simple, practical and extremely fast manner.
  • Essential characteristics of the invention are the modularity and flexibility of the device, which first of all allows prearranging the line and/or bus signal and deciding where to make the connections for the desired terminations.
  • the quick insulation displacement connection device for electrical connections which is the object of the present invention, permits drawing the signal from a pair of electrical cables 10 (twisted or parallel and protected by an outer insulation sheath), such as those of a bus, for example SCS, by means of pairs of metal blade 4 and 5, according to the principle of insulation displacement connection (IDC).
  • a pair of electrical cables 10 twisted or parallel and protected by an outer insulation sheath
  • an outer insulation sheath such as those of a bus, for example SCS
  • the aforesaid device comprises a first shaped containment element 1 (so-called “holder”), made of an insulating material, adapted to guide, maintain and prearrange the bus cables 10 for electrical connection, and a second contact-carrier element 6, it too made of insulating material, which bears on the bottom the pairs of metal contact blades 4, 5, enclosed within insulating walls 21 and adapted to make the electrical insulation displacement connection on each conductor of the bus cables 10, in order to draw the signal to be sent over the conductors 11 of a generic shunt electrical line.
  • holder shaped containment element 1
  • insulating material adapted to guide, maintain and prearrange the bus cables 10 for electrical connection
  • a second contact-carrier element 6 it too made of insulating material, which bears on the bottom the pairs of metal contact blades 4, 5, enclosed within insulating walls 21 and adapted to make the electrical insulation displacement connection on each conductor of the bus cables 10, in order to draw the signal to be sent over the conductors 11 of a generic shunt
  • the containment element 1 comprises a head 14, preferably T-shaped, which is mounted on a central circular body 15, provided with two lateral flanges 12, which terminate with respective elongated surfaces 13, adapted to be fit-inserted within respective seats 16 of the contact-carrier element 6.
  • a nut screw 18 is positioned which is adapted to receive a central pin 19, with suitable thread and pitch for the nut screw 18, pin 19 mounted on the shaped support 20 and passing through the centre of the contact-carrier element 6.
  • the threaded pin 19 is adapted to be engaged in the in the nut screw 18, in a manner such that, upon completed mounting of the containment element 1 on the contact-carrier element 6, the gradual insertion of the pin 19 inside the nut screw 18 causes the piercing of the insulation of the bus cables 10 by the metal blades 4, 5, which are inserted inside the seats of the retaining elements 17, so to achieve the electrical contact with the inner conductors of the bus cables 10.
  • the device is advantageously usable for electrical connections to make inside the shaped raceways 22, by pre-installing the containment element 1 inside the upper portion 23 of the raceway 22, in order to support the cables 10 of the bus signal and maintain them in position.
  • the head 14 of the containment element 1 is translatable inside the lower shaped seat 24 of the portion 23 of the raceway 22, while the contact-carrier element 6 is manoeuvrable by the installer by means of a standard tool, such as a socket wrench 25, which permits operating, by means of a bush 27, on the shaped lower portion 26 of the pin 20.
  • a standard tool such as a socket wrench 25 which permits operating, by means of a bush 27, on the shaped lower portion 26 of the pin 20.
  • the installer can obtain the pick-up of the signal of the bus cables 10, by means of the cables 11, by simply bringing the contact-carrier element 6 close to the containment element 1, by means of the socket wrench 25, and by rotating the wrench 25 at least several turns, without having to manually butt or connect the electrical conductors.
  • connection device can be analogously employed for applications on raceways (as in the above-described and illustrated example), where intake lines of the signal and/or bus are placed which are usable for the supply and transport of digital signals, as with analogue signal electrical lines, which employ twisted cables and/or ceramic isolators.
