Definitions

  • the present invention concerns a releasing fork for actuating springs of push-in terminals to dismantle connection devices inserted in said push-in terminals.
  • each terminal presents an actuating orifice offering an access to the spring that is designed for a screwdriver.
  • the present invention aims to solve all or some of the disadvantages mentioned above.
  • the present invention relates to a releasing fork for actuating springs of push-in terminals, the releasing fork comprising a handle and a plurality of prongs linked to and extending from the handle, each prong extending according to a corresponding extension direction and comprising an end fraction and a main fraction linking the end fraction to the handle, the end fraction having a decreasing section along the extension direction by moving away from the main fraction and the main fraction presenting two opposed and parallel cooperation surfaces extending parallel to the extension direction and defining a constant thickness of the main fraction.
  • the releasing fork enables to actuate a plurality of push-in terminals at the same time. For an equivalent result, a plurality of screwdrivers would be necessary. As there is a difficulty to hold a plurality of screwdrivers by hand, a releasing fork become an important tool for releasing a plurality of plugged conductors in one operation.
  • the end fraction with its growing section in direction of the main fraction facilitates the insertion of the prong in the actuating orifice of the push-in terminal.
  • the spring of the push-in terminal releases the plugged conductor.
  • the two cooperation surfaces of the main fraction that are extending in a parallel way allow the blocking of the releasing fork when inserted. Indeed, it maximizes the frictions with the spring and the actuating orifice wall.
  • the prongs are extending in the same plane called main extension plane.
  • the end fraction presents a contact surface that is inclined with respect to the contiguous cooperation surface of the main fraction.
  • each prong is rod with a rectangular or square base presenting said beveled or chamfered end at its free extremity.
  • the extension directions of the prongs are parallel and at least one of the prongs is shorter than the longest prong(s) according to the extension directions.
  • the prongs are extending in a parallel way from the handle and at least one of the prongs is shorter, that is to say extending less than the others according to the extension directions.
  • one or more of the prongs is shorter facilitates the insertion of the releasing fork in the corresponding actuating orifices of the push-in terminals. In this way, there is less resistance when the user pushes the releasing fork in the actuating orifices.
  • the insertion effort is distributed along the insertion path. This is not necessary to strongly push at the beginning of the insertion.
  • the plurality of prongs is constituted of three prongs that are reported on a transverse side of the handle and that are aligned transversally to the extension directions, the middle prong of the three prongs being shorter than the two other prongs.
  • a three prong releasing fork with a shorter middle prong is a good compromise for easily and reliably unplugging conductors. As the number of prongs is relatively low, the positioning with regard to the actuating orifices is easy. The length difference of the middle prongs distributes the insertion effort so that the user shall not press to heavily on the handle.
  • the releasing fork presents a hole for inserting a tool as a screwdriver, said hole extending transversally to the extension directions of the prongs.
  • the present invention also concerns a releasing assembly comprising two releasing forks as detailed above and a three phase connection device, the three phase connection device comprising an alignment of six electrical connectors extending in parallel, each electrical connector of a first group of three consecutive electrical connectors being electrically linked to a corresponding electrical connector of a distinct second group of three consecutive electrical connectors.
  • the three phase connection device is designed to electrically connect three phases of two electrical apparatus as contactors or breakers positioned side by side.
  • the first three electrical connectors constitute the first group and the following three the second group.
  • the releasing assembly thus comprises three complementary devices: the three phase connection device and two releasing forks to be inserted in corresponding actuating orifices to enable a single user to easily dismantle the three phase connection device.
  • each releasing fork remains positioned when inserted in the actuating orifices, the user can easily position the releasing forks one after another and then remove the three phase connection device.
  • each push-in terminal comprises an actuating orifice designed to access the spring from the outside with a dedicated tool and a connector opening designed to receive an electrical connector.
  • Said electrical connector comprises a conductive end in one part to be inserted without a tool inserted in the actuating orifice.
  • the insertion suffices to reach the end position.
  • each spring is configured to act as a harpoon to accept easily insertion but to block extraction.
  • the gap between each consecutive electrical connector of a same group is constant and corresponds to the gap between two consecutive prongs of the releasing forks.
  • each of the releasing forks comprises a marking for the positioning along a complementary marking of the three phase connection device so as to align each prong of the two releasing forks with the six electrical connectors.
  • the two releasing forks form an alignment extending in parallel to the alignment of the six electrical connectors.
  • the markings of the releasing forks and the complementary marking is designed to orient the contact surface of the release forks opposite to the electrical connectors.
  • the markings comprises each at least one triangle with an angle designed to be aligned with a corresponding angle of the complementary marking.
  • each triangle of the markings is positioned in a mirrored way with the complementary marking. As angles are pointing a same virtual point the middle, a precise alignment can be realized by the user. Once aligned, the releasing forks can be easily inserted in the actuating orifices.
  • the releasing assembly comprises a latch mechanism configured to releasably fix the two releasing forks on a back surface of the three phase connection device, the back surface being located opposite to the electrical connectors.
  • This provision allows having the releasing assembly as one entity that can be plugged in six connector openings.
  • the two releasing forks can be removed when the user would like to disassemble the three phase connection device from the six-connector openings.
  • the latch mechanism comprises a first part that is reported on the back surface and a second part that is comprised in each releasing fork.
  • the first part comprises lugs and the second part comprises slots.
  • the three phase connection device presents a cabling illustration indicating the electrical connections between the electrical connectors of the first group and the electrical connectors of the second group.
  • connection scheme can exist depending on the three phase connection device variant. This provision enables to easily realize several cabling possibilities as the user will take the proposer three phase connection device according to his needs.
  • the cabling illustration is located on the back surface of the three phase connection device.
  • the cabling illustration is located on a part of the back surface that is not in front of the releasing forks when cooperating with the latch mechanism. The cabling illustration is therefore always visible for the user.
  • the releasing assembly also comprises at least one common point connection device provided with two electrical connectors that are electrically linked, said two electrical connectors extending in a parallel way according to a gap corresponding to a gap between two consecutive prongs.
  • the releasing fork can be used to unplug a common point connection device as well as a three phase connection device.
  • the releasing assembly is therefore adaptable to the cabling necessities.
  • the present invention also concerns an electrical system comprising a releasing assembly as detailed above and two or more electrical apparatus, each electrical apparatus comprising a plurality of push-in terminals, the three phase connection device being adapted to connect the first group of electrical connectors to push-in terminals of one of the electrical apparatus and the second group of electrical connectors to push-in terminals of the other electrical apparatus.
  • the three phase connection device serves as a bridge between the two electrical apparatus, which is advantageous compared to connections realized by cables.
  • One connection operation is necessary instead of six when using individual cables between each push-in terminal. Thus, the risk of a bad cabling is reduced.
  • the two electrical apparatus can be three phase contactors with push-in terminals to realize starter, reverser or star-delta devices.
  • the releasing fork 1 for actuating springs of push-in terminals 3.
  • the releasing fork 1 comprises a handle 5 and a plurality of prongs 7 linked to and extending from the handle 5.
