Definitions

  • the present invention relates to an electrical connection device with insulation perforation, intended to electrically connect at least one conductor and an apparatus such as a socket outlet current or an actuator.
  • Devices of the kind previously mentioned generally include at least one perforation means mounted in a support, said means being intended on the one hand to be electrically connected to an electrical appliance and on the other hand, to be moved towards one of the conductors so as to perforate its insulating part and thus establish the connection electric.
  • a connector incorporating such a connection device is described in the patent application EP 0 665 608.
  • the electrical connection with a cable flat is made by a connector comprising a fixed upper block and a lower block to each other and between which the conductors are clamped. Contact elements individual are screwed into the upper block so as to penetrate the insulator of the ribbon cable and establish contact with the soul of the conductors.
  • connection requires as many screwing operations as there are connections to be made, which results in a relatively long connection time.
  • connection of the devices cannot be made directly on the connector.
  • Patent applications WO 95/03615 and FR 2331167 also describe devices using screwed contact elements.
  • US 5,055,065 describing a spike connection device used not to connect a conductor and an electrical device but to electrically connect two electrical conductors by perforating insulation.
  • Document EP 0 573 368 describes an electrical distribution device with quick connection making it possible to electrically connect the conductors of a flat cable to an electrical outlet.
  • the structure of this device is particularly bulky and complicated.
  • the present invention overcomes these drawbacks and proposes a device for connecting simple design allowing by eliminating the screwing operations, to obtain a faster connection, devices can be connected directly to the connector.
  • the device of the invention makes it possible to obtain in combination a low voltage drop and low penetration force.
  • the subject of the invention is a connector according to claim 1. Thanks to these characteristics, it is possible to make several connections at the same time, hence a significant gain in terms of connection speed and on the other hand, to connect the devices directly to the upper part of the connector.
  • the invention also relates to a connector according to any one of claims 2 at 20.
  • a connector C comprising mainly a lower part 1, or cradle, and an upper part 2, or cover, between which are tightened a set of conductors 3 forming a flat cable 4.
  • the cradle 1 forms a substantially U-shaped housing intended to receive the flat cable aforementioned 4 and comprises on its lateral faces la, projecting elements 5, 6, of section triangular cross. Each lateral face 1a of the cradle 1 thus comprises two elements protruding 5.6.
  • the cover 2 consists of a plate 7, the two edges of which 7a, 7b, each have two legs 8, 9 bent at 90 ° to the plate 7 (as more particularly visible in FIG.

  • connection M include connection blocks 11, 12, 13, three in this form of realization, intended to cooperate with openings 14, 15, 16 of rectangular shape formed in the cover 2 and intended to allow the passage of plugs or the like (not shown) belonging to said device.
  • connection block 11, 12, 13 consists of an elongated piece 17 of U-shaped cross section, comprising a base 18 and two wings 19, 20, extending substantially perpendicular to said base 18.
  • the base 18 extends to form two legs 21, 22, called the first legs, curved substantially in a U shape towards the inside of the blocks 11, 12, 13.
  • the two aforementioned wings 19, 20 also extend beyond the first legs 21, 22 to form two other legs 23, 24 called seconds, curved in the shape of U towards the inside of blocks 11, 12, 13 and the two ends 23a, 24a of which are located in look and in the vicinity of the rounded portions 21a, 22a, respectively of the first two legs 21, 22.
  • the elasticity of the legs is such that the elastic stress exerted on the first legs 21, 22 is the same as that exerted on the second legs 23, 24.
  • the base 18 of each block 11, 12, 13 also comprises on the one hand, a fixing orifice 25 of the block on the cover 2 and on the other hand, a spike connection device 26.
  • the block 11, 12, 13 is fixed to the cover 2 preferably by crimping.

  • D for example for a flexible wire of 2.5mm 2 , we can choose D between 1.8 and 2.5mm.
  • the diameter of the cylindrical part D is substantially equal to 2.1 mm for a flexible wire with a cross section of 2.5 mm 2 . This value makes it possible to decrease both the insertion force and the voltage drop.
  • the tip 27 and / or the strands of the conductors 3 will be tinned.
  • silvering or tinning of tips 27 guarantees a more constant voltage drop over time.
  • the conductors consist of tinned strands the use of a coated tip allows obtain a reduction in voltage drop of up to 25%, the best results being obtained with a tinned tip rather than silver.
  • the angle at the top ( ⁇ ) (fig. 3a) of the pointed part 29 is between 40 and 60 °, advantageously 40 °.
  • the length of the tip 27 is advantageously such that in the connected position, the end 29a of its conical part 29 is flush with or exceeds the lower part of the conductor 3 (fig. 3b).

  • This cover 2 will then fixed on the cradle 1 by snap-fastening, during the insertion of the projecting elements 5,6 in the openings 10 provided for this purpose in the cover 2.
  • the pins 27 of the connection blocks 11 to 13 will pass through the insulation 31 of the conductors 3.30 until reaching the soul of the drivers.
  • Connecting devices to conductors can then be established by introducing the contact elements in the form of a plug through the rectangular holes 14 to 16 provided in the plate 7 of the cover 2, then between the first and second elastic tabs 21, 22 and 23, 24 of the connection block corresponding, which tabs 21 to 24 form means for retaining the plugs on the blocks 11, 12, 13.
  • the connectors can be assembled longitudinally between them thanks to the assembly means 32 provided at the front and rear ends of the cradles 1 of connectors C, which guarantees a constant distance between the connectors, therefore between electronics.
  • connection device allowing by removing the screwing operations required in conventional systems, to increase the speed of connection.
  • diameter of the cylindrical part can be chosen, depending on different applications, depending on the constraints imposed relative to the fall of tension, or the penetration force of the tip.
  • the connector of the invention allows on the one hand in a single operation, to achieve several connections at the same time, resulting in a significant gain in connection speed, and on the other hand, plug the devices directly into its upper part.
  • This connector by its structure, is particularly compact, and allows a derivation of power in a minimum of space.
