Definitions
- the present invention relates to a connection device for electrically connecting to the at least one conductor to a strip or the like provided with contact elements, said device comprising a means of pushing the conductor between the contact elements driven by a screw.
- the pushing means comprises on the one hand, a well containing a screw immobilized in translation and on the other hand, a threaded pusher internally to receive said screw and mounted inside said well so as to be immobilized in rotation and movable in translation relative to the axis of the screw.
- the rotation of the screw under the action of a screwdriver causes the translation of the pusher and therefore the displacement of a conductor between the self-stripping contacts of a tubular connection clamp.
- connection clamp is located under the system screw, at a certain distance from the latter. This results in a significant bulk of the whole device.
- the present invention provides a particularly compact connection device whose maneuver is more in harmony with the usual actions of the electrician.
- the present invention relates to a connection device, characterized in that the pushing means comprises means for establishing the connection between the conductor and the bar by rotation of the screw, in one direction, and to establish the positive disconnection of the conductor by rotating the screw in the opposite direction to the previous one.
- connection is established by driving the screw in rotation in the direction clockwise, while disconnection is established by rotating the screw in the opposite direction to the direction schedule.
- the pushing means comprises a block comprising a tapped orifice intended to receive the aforementioned screw and at least one orifice intended to receive a driver.
- the pushing means is mounted inside a support, so as to be immobilized in rotation and movable in translation between a position connection position and a disconnection position of the conductor under the effect of actuation of the screw, said screw being immobilized in translation relative to the support.
- the pushing means comprises a screw screwed into a support and comprising at least one through orifice intended to receive the conductor, said orifice being shaped so that the actuation of the screw causes the movement of the conductor between a connection position and a disconnection position.
- the pushing means comprises a screw mounted mobile in rotation and immobilized in translation inside a support, said screw comprising at least an orifice intended to receive the conductor and shaped so that the actuation of the screw causes the conductor to move between a connection position and a position logout.
- it comprises at least one tubular connection clamp fixed mounted inside the support and having a split face forming two edges of blocking of the conductor, said edges carrying the contact elements.
- said clamp is mounted around the part of the block receiving the screw.
- the screw is immobilized in translation inside the support, the screw head resting on the one hand on the support and on the other hand, on the clamp.
- the invention also relates to a terminal block equipped with at least one connection device comprising one or more of the characteristics mentioned above taken alone or in combination.
- connection device D for electrically connecting at least one conductor C to a metal strip not shown.
- This device connection D mainly comprises a support in the form of a cage 1 inside which is mounted a pushing means M, formed by a screw system 5, said support 1 comprising on its front face 2 an opening 3 intended for the passage of a cable C and on its upper face 7, an opening 4 intended for the passage of a tool for actuating a screw 5, such as a screwdriver, in the case of the embodiment of Figure 1, or the passage of the screw itself 6 in the case of the embodiment illustrated in FIG. 8.
- connection block 8 mainly comprises a connection block 8, a connection clamp 9 and a screw 5. Note also the presence of an electrical connection bar 30.
- This block 8 consists of a part 10, having an orifice 11 intended to receive the conductor C and a massive part 12 comprising a threaded orifice 13 of substantially cylindrical shape and intended to receive the screw 5.
- connection clamp 9 is constituted by a generally tubular piece having on its front face 9a, two edges 14, 15 said to block the conductor C, said edges 14, 15 comprising at one of their ends self-stripping elements 16, 17.
- the rear face 9b of said clamp 9 has a portion 18 extending beyond said self-stripping elements 16, 17, so that when the clamp 9 is mounted on the block 8 around its part 12 receiving the screw 5 ( Figure 4), the self-stripping elements 16, 17 are located slightly at the above conductor C. It is also seen in this figure, that means 18 are provided on block 8 and clamp 9 to facilitate the relative translational movement of block 8 by compared to clamp 9.
- the block 8 has a projecting part 19 constituting a means of foolproof.
- the screw 5 and the block 8 are each equipped with a position indicator respectively 20 and 21 and that stop means 22 (free stops) will be provided in part on the head 5a of the screw 5 and on the support 1 in order to limit the stroke of the block 8 and of the cable C between two positions corresponding to the connection and disconnection positions of the conductor C.
- the orifice 11 provided for the conductor C in the block 8 is inclined towards the lower part 26 of the support 1 so as to allow pre-maintenance of cable C before connection.
- the support 1 has on its rear face 23 an opening orifice 24 lying in the extension of the orifice 11, block 8 and intended to allow the evacuation of the insulating material after connection in the event of insulation jamming in the terminal.
- the pushing means M comprises a screw 6 screwed through the upper part 7 of the support 1 and having an orifice 25 for introduction of cable C allowing said cable C to move in translation parallel to the axis of the screw 6 between a connection part of the conductor C with the strip and a position of logout.
- the electrician will drive the screw 5 in the direction opposite to the previous one. Thanks to the presence of the position indicators 20 and 21 provided respectively on screw 5 and on block 8, the electrician will be able to check the open or closed position (connected or not connected position) of the terminal, which is important considering that conductor C may very well be in the position of premainten without being connected.
- connection will be obtained in the same way by driving the screw 6 clockwise, which will cause the displacement of the conductor C down, and conversely disconnection will be established by rotation of screw 6 in the opposite direction.
- a quick connection device has been produced (1/4 turn for the connection), which, in particular because the block is inside the clamp, in unconnected or connected position, is particularly compact, and whose operation is in harmony with the usual actions of the electrician namely, the operation of a screwdriver clockwise to make a connection and counterclockwise to make a connection logout.
- this device can advantageously be used in a terminal block with by example the same connection block comprising several cable insertion holes in parallel, said block being driven by means of a single screw.
