Application to the connection of at least one insulated electrical conductor (11).

Description

  • The present invention relates generally to self-stripping connectors, that is to say the connectors which, intended for the connection of at least one insulated electrical conductor, themselves provide local stripping of the latter. ci, by moving its insulator.
  • It can be either a connector acting in isolation as such, for example for the connection, between them, of two insulated electrical conductors, or for the connection of such an electrical conductor to any electrical apparatus, as a connector which, integrated into such electrical equipment, for example forms a connection terminal for the latter.
  • Overall, a self-stripping connector of the type concerned comprises at least one conductive element assigned to a contact slot in which the insulated electrical conductor to be connected must be forced.
  • One of the problems to be solved in the production of a self-stripping connector of this type is due to the very fact that such an electrical conductor must be forced into a slot.
  • It is necessary, in fact, to have means suitable for allowing this electrical conductor to be pushed into this slot.
  • In the French patent which, filed on February 2, 1986 under No 86 01191, was published under No 2.593.969, there is provided, to do this, a clean wall to circulate in the slot.
  • This arrangement, which has the advantage of allowing a push of the electrical conductor on either side of the slot, is satisfactory.
  • However, it has drawbacks, which are as follows.
  • First of all, by the very fact that it must be thin enough to engage in the slot, the wall thus implemented inevitably presents a certain brittleness, and this all the more since, in practice, it is made of synthetic material.
  • Finally, at the end of the travel, the stripped part of the electrical conductor concerned is most often butted only on one side, that of the wall having served to push this electrical conductor, while being more or less free on the opposite side.
  • It therefore has every freedom to flourish on this last side as time goes by, in particular when it is of the multi-strand type, to the detriment of its contact pressure with the lips of the slit, and, therefore, to the detriment the quality of the electrical contact assured.
  • In the Japanese patent application published under No. 59-205171, there is provided a self-stripping connector comprising two conductive elements, which are mounted movable relative to each other between two positions, one of opening , the other closing, and each of which has, opening onto one of its edges, a contact slot suitable for ensuring the local stripping of an insulated electrical conductor when such an insulated electrical conductor is forced there, with, from one to the other of these two conductive elements, a crossed arrangement of their respective contact slots which increases when they pass from their open position to their closed position.
  • Thus, due to the increasingly accentuated crossing of the contact slots of these two conductive elements when they pass in the closed position, the stripped part of the insulated electrical conductor to be connected is advantageously confined both on one side and on the other. 'other.
  • However, a self-stripping connector of this type is difficult and delicate to implement, since the force to be exerted on the insulated electrical conductor to be connected must not only be sufficient to allow its local stripping but must also be sufficient important for jointly ensure the passage into the closed position of the two corresponding conductive elements.
  • In practice, a tool, of the pliers type, is essential.
  • In addition, the two conductive elements of this self-stripping connector do not lend themselves to possible subsequent reopening.
  • The present invention generally has an arrangement which, while advantageously leading to effective holding of the stripped portion of the electrical conductor to be connected, makes it very simple to avoid the above drawbacks.
  • More specifically, it first relates to a self-stripping connector of the kind comprising at least two conductive elements, which are mounted movable relative to each other between two positions, one of opening , the other closing, and each of which has, opening onto one of its edges, at least one contact slot suitable for ensuring the local stripping of an insulated electrical conductor when such an insulated electrical conductor is forced into it, and this self-stripping connector is, in general, characterized in that, jointly, the contact slots of its conductive elements open onto edges of these conductive elements which, for their closed position, are generally opposite the one with respect to the other, and said conductive elements are able to intersect one another by means of their said contact slots for their said closed position.
  • Thus, according to the invention, the two conductive elements which mutually ensure the thrust, one with respect to the other, in their respective contact slots, of the electrical conductor to be connected, and which, at the end of this thrust , jointly ensure the containment of its bare part.
  • This results in a very secure holding, in all directions, of this bare part, which is in particular particularly advantageous for multi-strand electrical conductors.
  • Admittedly, it is known, from the French patent application filed on May 13, 1976 under No. 76 14448 and published under No. 2,351,514, a self-stripping connector whose two conductive elements each have a slot opening on their opposite edges .
  • However, this slot is only a contact slot for one of these conductive elements.
  • As is apparent from the drawings, in fact, the other conductive element does not have a sufficient height to reach the conductive core of an insulated electrical conductor.
  • It is therefore in practice only a claw capable of gripping in its insulating part such an insulated electrical conductor.
  • Furthermore, and above all, it is nowhere suggested in this French patent application that the two conductive elements can intersect one another by their slots in the closed position.
  • In practice made of metal, the conductive elements of the self-stripping connector according to the invention do not exhibit any brittleness.
  • In addition, after its closure, the self-stripping connector according to the invention can advantageously be easily reopened if desired, with easy release of the electrical conductor (s) that it previously enclosed.
  • This is all the more so since, according to a preferred embodiment, for at least one of the conductive elements, and in practice for each of them, the contact slot affects a portion of this conductive element which, to allow its intersection with the other, extends generally transversely, at an angle between 0 and 90 °, relative to the general direction of its current part, or, more precisely, relative to the general direction of elongation of the assembly in the closed position.
  • Consequently, the contact slot of each of these conductive elements can advantageously be relatively wide, which facilitates the production thereof, and which, when opened, allows immediate release of the electrical conductor (s) concerned.
  • In short, the self-stripping connector according to the invention, which is advantageously capable of being implemented without tools and requiring little effort, advantageously blocks in all directions, in the closed position, the conductor (s) electrical it encloses, it allows, when opened, easy wiring of this or these electrical conductors, it is compatible with all types of electrical conductors, single-wire or multi-strand, likely to be affected, it is advantageously in a very small overall size transversely with respect to this or these electrical conductors, thereby facilitating combing, that is to say a paralleling, of these, and, by the possibilities it offers to engage this or these electrical conductors from very different angles and / or in very different directions, it is advantageously suitable for many embodiments, at least some of which are very simple, and / o u many applications, by allowing multiple combinations of connection with other connectors or other electrical equipment.
  • Incidentally, the self-stripping connector according to the invention is advantageously capable, in the closed position, of constituting by itself a cable clamp, thereby advantageously ensuring mechanical resistance of the electrical conductor concerned upstream from its connection point; it is also advantageously capable of constituting by itself, downstream of this connection point, a sectioning member capable of cutting this electrical conductor.
  • Finally, when the two conductive elements of the self-stripping connector according to the invention intervene within a housing having at least two parts, one per conductive element, which, movable relative to each other, are thus able to allow the drive, one relative to the other, from one to the other of their open and closed positions, of these two conductive elements, each of the parts which such a housing thus comprises is advantageously reinforced by the presence of such an element conductor, which is favorable to its good behavior.

  • As illustrated in these figures, the self-stripping connector 10 according to the invention, which is provided for the connection of at least any electrical conductor 11 with conductive core 12 and insulating sheath 13, comprises, generally, in a known manner per se, two conductive elements 15, which, according to methods described in more detail later, are mounted movable relative to each other between two positions, one of opening, the other of closing, and whose each one, opening onto one, 16, of its edges, a contact slot 18 suitable for ensuring the local stripping of such an electrical conductor 11 when this electrical conductor 11 is forced into it, that is to say when it is forcibly engaged therein.
  • According to the invention, the contact slots 18 of the conductive elements 15 open onto edges 16 of these conductive elements 15 which, for their closed position, FIG. 3 for example, are generally opposite one with respect to the other, and, together, these conductive elements 15 are able to intersect one another in favor of these contact slots 18 for such a closed position.
  • In the embodiments more particularly shown in FIGS. 1 to 11, the two conductive elements 15 are in one piece with one another, these two conductive elements 15 coming one and the other from a single and same blank, for example a simple strip, suitably cut and folded.
  • In practice, in these embodiments, the conductive elements 15 are identical to each other, and, for each of them, the contact slot 18 affects a portion 21 which extends generally transversely, along a angle A between 0 and 90 °, relative to the general direction of elongation D of the assembly in the closed position.
  • In Figures 1 to 4, the angle A is substantially equal to 60 °.
  • As a variant, it may for example be substantially equal to 45 °, FIG. 5, be substantially equal to 90 °, FIG. 6, or be substantially zero, the corresponding portions 21 of the conductive elements 15 then being substantially contiguous one with the other, Figures 7 and 8.
  • In practice, the portion 21 of a conductive element 15 thus presenting the contact slot 18 extends between two fold lines 22 affecting transversely, in opposite fold directions to each other, this conductive element 15, and the contact slot 18 itself extends transversely, parallel to the fold lines 22, over a depth greater than at least half the height of such a conductive element 15.
  • In the embodiments shown, the lips of such a contact slot 18 are parallel to each other, and, at its outlet, this contact slot 18 is connected to a large engagement V 24.
  • In the embodiments shown, the portion 21 of a conductive element 15 thus assigned a contact slot 18 extends generally transversely between two portions 25, 26 of the current part of this conductive element 15 which are parallel to the one to the other being both parallel to the general direction of elongation D of the assembly in the closed position.
  • In the embodiment more particularly shown in the figures in 4, the two conductive elements 15 are established symmetrically with respect to one another with respect to a common median plane of symmetry passing through this general direction of elongation.
  • They form erect wings substantially perpendicular to a common central sole 30, by being attached by folding to the latter along its longitudinal edges, at one of the ends of the latter.
  • From its corresponding transverse edge, the common central sole 30 is affected, longitudinally, in its central region, by a slot 31 dividing it into two branches 32 over part of its length.
  • In line with these branches 32, the ends 33 of the portions concerned of the conductive elements 15, in this case their portion 25, are generally rounded in a semicircle.
  • They thus jointly form a hinge pin pivot A transverse to the general direction of elongation D of the assembly in the closed position.
  • For reasons which will appear below, on the side opposite to the common central sole 30, the edge 16 ′ of that of the conductive elements 15 which must span the other in the closed position is, from a shoulder 34, in elevation relative to that of the other.
  • In the embodiment shown, the two conductive elements 15 are moreover capable of forming jointly, for their closed position, at a distance from their contact slots 18, on the one hand a cable clamp 36, and on the other hand a sectioning member 37.
  • The cable clamp 36 results from tongues 38 coming, by a puncture, in correspondence with one another, from the portion 25 of these conductive elements 15.
  • The sectioning member 37 results from angle returns 39, which came from the portion 26 of these conductive elements 15 and whose edge is biased.
  • Finally, in the embodiment shown, the self-stripping connector 10 according to the invention further comprises, at the other end of the common middle sole 30, two other wings 40, which, erected perpendicular to this common middle sole 30 , are intended to jointly form a connection member 41.
  • If desired, the self-stripping connector 10 thus formed can be implemented in isolation, without any housing.
  • In this case, its conductive elements 15 are preferably each insulated by a protective coating, only the lips of their contact slot 18 remaining exposed.
  • However, in the embodiment shown, and as illustrated in FIG. 1, this self-stripping connector 10 acts as a comb, that is to say in parallel with others, not shown, inside. an insulating housing 43 having at least two parts 44, one per conductive element 15, which, movable relative to each other, are thus able to allow the drive, one relative to the other, from one to the other of their open and closed positions, of its conductive elements 15.
  • In the embodiment shown, the part 44 of this housing 43 associated with the conductive element 15 intended to stepping over the other forms a pivoting flap, in which, for its drive by it, this conductive element 15 is anchored by the part in elevation of its edge 16 ', precisely raised for this purpose, and which, by a line of lesser thickness , is articulated to a fixed part 45.
  • The other part 44 of the housing 43 forms, parallel to the fixed part 45, a bottom on which the other conductive element 15 and the central sole 30 common to the assembly rest.
  • This part 44 forming the bottom has a bore 46, for the engagement of an electrical conductor 11 to be connected.
  • In a transverse end wall 47 disposed in line with the connection member 41, the housing 43 also has a bore 48 suitable for the passage of any connection pin, in practice a flat connection pin, not shown, capable of cooperating in engagement with this connection member 41.
  • In practice, to thus contain, parallel to one another, several self-stripping connectors 10, the housing 43 forms, parallel to each other, several housings 49, which are delimited two by two by ribs 50 projecting from the part 44 forming the bottom, and which each have a bore 46 and a bore 48.
  • For its fitting onto the ribs 50, the part 44 forming a flap has grooves 51.
  • However, for the implementation of a self-stripping connector 10 according to the invention, the procedure is as follows.
  • The part 44 forming a flap of the housing 43 being in the open position, and therefore also driven by it, the conductive element 15 of the self-stripping connector 10 intended to span the other, the electrical conductor 11 to be connected is engaged , as shown schematically in broken lines in Figure 1, between the two conductive elements 15, by means of the bore 46 of the part 44 forming the bottom.
  • The part 44 forming a flap is then folded back in the closed position, parallel to the part 44 forming the bottom.
  • During the corresponding path, the conductive element 15 linked to this part 44 forming a flap engages the electrical conductor 11, and, driving it with it while engaging on it, forces it to bend at right angles and to engage on the other conducting element 15.
  • The corresponding closing force being continued, the electrical conductor 11 is forced to engage, simultaneously, in the contact slot 18 of one and the other of the conductive elements 15.
  • Jointly, by their contact slots 18, which then have concavities turned towards one another, the two conductive elements 15 come to intersect, each passing through the other in favor of the contact slot 18 of the latter and its own contact slot 18.
  • The result is a local stripping of the conductive core 12 of the electrical conductor 11 by incision and discharge of the insulating sheath 13 thereof, until contact is established between this conductive core 12 and the lips of the contact slot 18 of each of the conductive elements 15, FIG. 4.
  • The stripped part of the conductive core 12 of the electrical conductor 11 is therefore advantageously perfectly confined in all directions in the contact slots 18.
  • Jointly, upstream of these contact slots 18, the electrical conductor 11 is caught between the tongues 38 constituting the cable clamp 36, which ensures its mechanical retention.
  • Together, also, downstream of the contact slots 18, the angle returns 39 constituting the sectioning member 37 eliminate, if necessary, and as shown diagrammatically in broken lines in FIG. 3, the overperfluential section of the electrical conductor 11.
  • In the foregoing, the electrical conductor 11 to be connected has been engaged from below, transversely with respect to the general direction of elongation D of the self-stripping connector 10 in the closed position, before being aligned, by folding, with this general direction of elongation D.
  • However, as a variant, in particular when a self-stripping connector 10 is used in isolation, this electrical conductor 11 can be engaged from the side, transversely with respect to the general direction of elongation D, FIG. 5.
  • In the foregoing, the conductive elements 15 intersect obliquely.
  • However, as a variant, they can intersect flat, either that the corresponding angle A is equal to 90 °, FIG. 6, or that this angle A is substantially zero, FIGS. 7 and 8.
  • In the case where the angle A is equal to 90 °, the electrical conductor 11, once connected, necessarily extends in the general direction of elongation D of the assembly in the closed position, as described with reference to the figures 1 to 4.
  • In the case where the angle A is zero, it necessarily extends perpendicular to the general direction of elongation D, that is, engaged by the side, as described with reference to FIG. 5, it is also perpendicular to the conductive elements 15, as shown in FIG. 7, that is, engaged from below, as described with reference to FIGS. 1 to 4, and as shown diagrammatically in broken lines in FIG. 11, it remains parallel to these conductive elements 15, favored by an S-fold at the right of these, as shown in Figure 8.
  • As will be noted, when passing into the open position, the conductive element 15 intended to span the other rolls on the common central sole 30 by the edge of its rounded end 33.
  • Of course, the respective roles of the conductive elements 15 can be reversed, and, like the other, that associated with the part 44 forming the bottom of the housing 43 can be anchored in the latter.
  • In the embodiment shown in FIG. 9, the common central sole 30 extends continuously, and the conductive elements 15 are established symmetrically with respect to each other, no longer with respect to the median plane of symmetry of this common middle sole 30, but relative to its center.
  • In other words, they are generally arranged upside down with respect to this common middle sole 30.
  • Furthermore, in this embodiment, the cable clamp 36 is formed by angled returns 38 ′, which, coming from the ends of the common central sole 30, beyond the portions 21 of the conductive elements 15 having their slot contact 18, each have, on their edge, a semi-circular notch.
  • However, as before, and as shown, tongues 38 can also be provided on the conductive elements 15.
  • In the embodiment shown in FIG. 10, the conductive elements 15, cut from the same strip, only connect to each other by a transverse fold line 53, which, formed longitudinally in this strip, in the median zone thereof, connects to each other two notches slitting it, head to tail, half-width, from its opposite edges and constitutes the corresponding axis of articulation A.
  • Furthermore, in this embodiment, the fold lines 22 delimiting the portions 21 of the conductive elements 15 affected by their contact slot 18 extend in arcs of a circle, centered on this axis of articulation A, and therefrom is the same for this contact slot 18.
  • Finally, in this embodiment, the connection member 41 is formed by the conductive elements 15 themselves, the end of their portion 25 opposite the transverse fold line 53 being duly shaped accordingly.
  • As shown, this connection member 41 is intended to cooperate with a flat pin.
  • However, as a variant, it can just as easily be shaped so as to be able to cooperate with a spindle of another type, and, for example, with a round spindle.
  • Anyway, coming from the conductive elements 15, it is only reconstituted when, as shown diagrammatically in broken lines in FIG. 10, these conductive elements 15 are in the closed position.
  • In the embodiment shown in FIG. 11, two conductive elements 15 are provided at each end of the common central sole 30.
  • For one of them, the conductive elements 15 intersect, for example obliquely, as shown, as described with reference to FIGS. 1 to 4.
  • For the other, they intersect for example flat, as also shown, as described with reference to FIG. 8.
  • In the embodiment shown in Figures 12 to 14, the two parts 44 that comprise the housing 43 for driving the conductive elements 15 form jaws which, articulated to a common median block 54, are thus pivotally mounted one relative to each other, and these conductive elements 15 are constituted by blades, which are connected to each other, in rotation, by a rivet 55 constituting their axis of articulation A and formed for example of a boss coming from one and crossing the other, and which, each having two contact slots 18 symmetrical to one another with respect to this axis of articulation A while each extending in an arc of a circle centered on it, are substantially contiguous and are capable of intersect at substantially zero angles to the right of these two contact slots 18.
  • Together, the housing 43 forms, parallel to the articulation axis A, in line with the contact slots 18 of the conductive elements 15, and on either side of the parts 44 forming jaws, two chimneys 56, which, each respectively , are suitable for the engagement of two electrical conductors 11 to be connected.
  • In addition, each of the parts 44 forming the jaw of the housing 43 has, projecting from its internal face, a bead 57 by which it is capable of acting jointly on one and the other of the conductive elements 15, for the passage of those -from their open position, Figure 12, to their closed position, Figure 14.
  • In the embodiment shown in Figures 15 to 16, the two parts 44 of the housing 43 one form a barrel the other a body in which this barrel is rotatably mounted.
  • Part 44 forming a barrel is capable of driving in rotation, with play, one of the conductive elements 15, while that forming a body is integral with the other of these.
  • In the embodiment shown, these conductive elements 15 are constituted by blades which, at their ends, have, for their attachment to the part 44 forming a barrel or to the part 44 forming a body, returns 58 directed in a direction for the 'one of them and in opposite direction for the other.
  • As before, the two conductive elements 15 thus formed each have two contact slots 18 symmetrical to one another with respect to their axis of articulation A, which is formed by the axis of rotation of the part 44 forming a barrel , and in line with the contact slots 18 of that of these conductive elements 15 which is integral therewith, this part 44 forming a barrel has, parallel to this articulation axis A, for engagement electrical conductors 11 to be connected, two oblong passages 59.
  • In the embodiments shown in FIGS. 18 to 21, the common central sole 30 constitutes by itself the two parts 44 of the housing 43, these two parts 44 then each forming a flap, being connected one to the another by a middle part 60, and each carrying, projecting on its inner surface, in one piece with it, two conductive elements 15, adapted to intersect each respectively with the two conductive elements 15 carried by the other.
  • Therefore, the housing 43 is no longer made of insulating material, but of metal.
  • However, if desired, it can be coated with an insulating coating.
  • Anyway, once closed, this housing 43 has a generally rectangular shape, in the manner of a nut, and, for the passage of a screw 62, it has, in its central area, a recess 63 .
  • In the embodiment shown in FIGS. 18 and 19, this recess 63 extends continuously, in a buttonhole, from one of its parts 44 forming a flap to the other.
  • Alternatively, Figures 20 and 21, it has a closed outline.
  • The housing 43 can thus be substituted for a nut in any connection terminal, the screw 62 cooperating for example with a bore 64 provided for this purpose in the corresponding support 65.
  • In the embodiment shown in FIGS. 18 and 19, the conductive elements 15 are of the type of those, with a portion 21 provided with a contact slot 18 interposed obliquely between two parallel portions 25, 26, described with reference to the figures 1 to 11.
  • As a variant, FIGS. 20 and 21, these are simple flaps which, coming from the edges of the parts 44 forming a flap of the housing 43, are erected by folding perpendicular to these parts 44, and which are directly affected by the corresponding contact slot 18.
  • In both cases, cable clamps 36 are provided.
  • Of course, the present invention is not limited to the embodiments described and shown, but encompasses any variant and / or combination of their various elements.
  • In particular, instead of being rotatably mounted relative to one another, the conductive elements according to the invention could just as well, at least in the final phase of their intersection, be mounted movable parallel to themselves .
