Definitions

  • the present invention relates to electrical connections between conductors of an electrical cable and electrical pins such as pins mounted on a printed circuit substrate and / or rigid electrical terminals of components, in particular for interconnections between chassis of electrical equipment, circuits printed matter, electronic components or electrical elements with rigid connections.
  • connections between conductors and rigid pins can be made by standard type coiled connections.
  • connection terminal of modular structure, making it possible to easily and quickly make such connections and also allowing, at will, the cutting or closing of all the connections concerned.
  • the electrical connection terminal is of the modular type. It includes identical contact supports such as 1 and 1 ', which will each receive twelve contacts such as 2, an insulating element 3 for the alignment of contact supports 1 and 1', a housing-cover 4 ensuring the blocking of the 'element 3 on the contact supports and a cam 5 rotatably mounted in the contact supports 1 and 1' for the simultaneous actuation of all the contacts 2 and therefore putting them in the so-called rest position or in the so-called contact position.
  • this terminal is intended to ensure the connection between electrical conductors 6 and aligned electrical pins 7.
  • each of the contact supports 1 and 1 ′ is in the form of an elongated parallelepipedic block with internal longitudinal groove 10 open on almost all of its upper face .
  • Each of these supports 1 and 1 ′ comprises, along each of their two large lateral faces, six external cells 11 formed on the height of these large lateral faces and arranged, from one face to the other, in staggered rows. Each also includes along the longitudinal walls of the groove 10 six other cells, said internal cells, 12, extending to the underside of the support. These six internal cells 12 are interposed between the six external cells formed on the corresponding large side face of the support, that is to say are vis-à-vis respectively with the six external cells of the large opposite side face.
  • the twelve internal cells 12 of the support, with the twelve external cells 11 of this same support define the housings for the twelve contacts 2 that each support 1 or 1 ′ can receive.
  • Each of the supports 1 and 1 ′ also has a longitudinal groove 13 on each of its two large lateral faces, in the vicinity of the lower edge of these faces, coming to cut the six external cells 11.
  • the internal groove 10 is of a depth close to half the height of the support and is at the bottom 14 rounded. It defines the housing of the cam 5, the rounded bottom constitutes the bearing surface.
  • This groove 10 opens onto the two small side faces each having an opening 15 in the form of an arch open on the side of the lower face, the semi-circular apex of these arched openings and the rounded bottom of the groove 10 limiting the possible vertical movement of the cam 5 in its housing.
  • These supports 1 and 1 ′ are made of plastic, for example polycarbonate; they advantageously come from molding.
  • the contacts 2, one of which is shown on a larger scale in FIG. 2 are spring-type contacts of general U shape.
  • one of the branches of the contact 2, identified at 20 is intended to be connected to the conductor 6 sheathed in insulation, by making a contact by stripping edges.
  • this branch 20 is itself in the form of a U open towards the outside of the contact 2 and has, laterally internal edges 21 stamped coming through the insulating sheath of the conductor 6 during its insertion according to arrow F and keeping it in this branch 20, to make the electrical connection of the conductor 6 and the contact 2.
  • This branch 20 has, in addition, stamped stamped lugs 22, oriented towards the inside of the contact 2, gripping in the housing 11 of the support 1 or 1 ′, receiving this branch for maintaining this contact.
  • the other branch 23 of the contact 2 is in the form of a flat blade and has in a intermediate part a simple deformation 24 forming a boss towards the outside of the contact 2.
  • This branch 23 is intended to come into contact with one of the pins 7, the deformation 24 then locating the electrical contact to be made.
  • the contacts 2 will be made of elastic metal and advantageously covered with a protective coating against corrosion; this protective coating will be for example tin-lead.
  • this protective coating will be for example tin-lead.
  • the springs are inserted into their housings from the underside of the support 1 or 1 'which receives them, being, one on two alternating mounted of 180 0.
  • the branches 23 of the successive contacts 2 on one of the supports 1 or 1 ′ will be arranged in the successive internal cells 12 of this support, which are alternately on one and the other of the walls of the groove 10, while the branches 20 successive contacts are housed in the external cells 11 which are alternately on one and the other of the side faces of the support concerned.
  • the branches 23 will extend to the top of their respective internal cells.
  • the insulating element 3 is an inverted U-shaped section profile and of length equal to that of the set of supports 1 and 1 'which it will cover.
  • This profile 3 has two longitudinal bosses 30 on portions of its branches, in the vicinity of its base, these bosses being obtained by an extra thickness given to its base and to the adjacent portions of its lateral branches.
  • It also has two longitudinal tabs 31 projecting towards its internal part and forming flanges on its two lateral branches. These tongues 31 keep the supports 1 and 1 'in alignment by fitting into the grooves 13 of the supports.
  • This profile 3 is of higher height than that of the supports 1 and 1 'and comes, when it covers them, to provide above them ( Figures 3, 5A, 5B and 6) a free space 33 forming a housing for the conductors 6 which will be connected to the contacts 2.
  • the housing-cover 4 is made of a ferromagnetic conductive material, for example steel known under the references Z8 C17.
  • This casing-cover 4 is, like the element 3 which it covers, of U-shaped section and has two longitudinal deformations 40 on these two lateral branches, corresponding to the longitudinal bosses 30. It has at one end a tab 41 substantially in the extension of his upper face, on which is housed a collar 42 with screw tightening 43 which will hold the cable of conductors 6 ( Figures 3, 4) to be connected to the contacts 2.
  • This collar 42 will also ensure, as can be seen in Figures 3 and 4 , the electrical connection of the housing-cover 4 to an electrical earth and to the cable screen, by a screen continuity wire 61 with terminal Faston terminal 62, the housing-cover 4 serving as an electromagnetic screen for the circuits that it contains.
  • the front face 44 of the housing-cover 4 is closed by an end portion folded down from its upper face.
  • This 'front face 44 is provided with a circular passage 45 for access to the cam 5, in its housing supports 1 and 1'; it is further provided with a small circular opening or hole 46 for holding the cam 5 in position for which the closing of the contacts is ensured.
  • this assembly 3-4 is mounted on the supports 1 and 1 ′ equipped with their contacts 2.
  • the rigid terminal thus produced also has its control cam 5.
  • this cam 5 is slightly longer than that of the assembly 3-4 covering the supports 1 and 1 ' . It is generally cylindrical in shape and has over almost its entire length two diametrically opposite flats 50 (FIGS. 5A, 5B and 6). At one end forming a rounded end it has a peripheral groove 51, while the opposite end forms an actuation handle 52.
  • This actuation handle which will be external to the housing-cover 4 has a positioning lug 53 projecting towards the front face 44 of the casing-cover, disposed substantially in the axial plane of the cam cutting the flats and in order to be able to come and penetrate into the bore 46 to maintain this cam in position.
  • This cam 5 is made of insulating material. It is introduced, through the passage 45 of the front face of the housing-hood into the groove 10 of the supports, coming to rest on the rounded bottom of the groove of the supports, its rounded end projecting beyond supports 1 and 1 '. This cam 5 introduced into the supports improves their alignment. It is held in position using a clip 55 inserted in the groove 51.
  • connection terminals 7 ready to be inserted on pins 7, of the type with wound connections, aligned in two rows as shown in FIGS. 3 and 4 and more particularly in FIG. 7.
  • connection terminals designated by A, B, C, and D identical to each other and of the type of that illustrated in Figures 1, 3 and 4.
  • These terminals are inserted or ready to be inserted on double rows of pins 7, projecting from a printed circuit substrate 8, this substrate possibly being an interconnection card for circuits or electrical elements or electronic components to be connected via connection terminals to different conductors of electrical cables.
  • connection terminal connected to its conductor 6 and arranged in relation to one of the pins 7 extending beyond the interconnection card 8.
  • This pin 7 belongs like the other pins similar to one or more electrical elements 9 such as that shown in dotted lines, for example to a zero insertion force connector for printed circuit boards carrying various components, producing by individual contacts on tracks printed on one of the edges of this card the inputs or outputs for the circuit formed on this card (not shown).
  • the pins 7 are inserted at the bottom of the internal cells 12 of the contact support 1 (or of the contact support 1 '). This insertion is made possible during the positioning of the branches 23 of the contacts 2 along the top of their respective internal cells 12, that is to say by actuation of the cam 5 one of the flats of which then comes opposite the branch 23 of each of the contacts 2 which then completely releases the bottom of its cell.
  • the branch 23 of the contact 2 and the pin 7 both housed in the same internal cell are then in contact with each other.
  • the terminal being mounted on the interconnection card 8, the actuation of the cam 5, by its handle 52 by bringing the lug 53 carried by the handle in the bore 46 of the housing-cover 4, causes the semi portions to be put -cylindrical of the cam opposite the branches 23 of the contacts 2. Under these conditions the pressure exerted on these branches, causes them to sink towards the bottom of their cells 12 and therefore bring them into contact with the pins 7 which are respectively housed there.
  • connection terminal will be controlled at will in the so-called rest position for which the contacts 2 and the pins 7 are non-contact and for which it can be freely disengaged from the card 8 or in the so-called contact position for which the pins 7 will be connected to the conductors 6.
  • the terminal included two contact supports each capable of receiving twelve contacts. It is obvious that the terminal can have a different number of contact supports and that these can also receive a different number of contacts. Of course also, it is possible to mount all or part of the contacts 2 on the support which receives them as a function of the arrangement of the pins 7 in the two rows of pins to be connected to the same number of electrical conductors.
