Definitions
- terminal blocks are used, in particular in the electrical cabinets, to electrically connect two or more electrical conductors together.
- junction blocks are known to engage a ⁇ conductor rail, provided with an insulating housing having two main faces (one partially open and the other closed) and side faces connecting the main faces.
- this housing are provided two conduits for introducing portions of ends of electric cables and a receiving housing of a subassembly formed of a conductive strip and two spring blades.
- the bars of such subassemblies comprise two cells for receiving the end portions of the electric cables, each cell being delimited by surfaces of which one form a seat.
- Each leaf spring has two branches connected to one another by a curved section.
- each spring blade The end portions of the two branches of each spring blade are previously engaged in the corresponding cell to form the subassembly to be introduced into the receiving housing by the open face of the housing.
- each cable introduction duct formed in the housing opens into a corresponding cell of the bar.
- Each leaf spring is adapted to deform to leave the end portion of a cable, when engaged in said cell, to fit between the seat and an end edge of the leaf spring and, if the cable is then urged to be removed from the block, to wedge the end portion of the cable between the seat and the end edge.
- the offset of the section provided with a stop outside and at a distance from the cell allows the leaf spring to cooperate with the bar under more favorable mechanical conditions than in the case where the end portions of the two branches of the blade spring are inserted into the cell.
- the insertion force of an electric cable is reduced here, thus improving the comfort of use, while being sufficient to ensure good electrical contact.
- the inclination of the ear in the direction of the cell makes it possible, by cooperation with the spring blade, to take up the majority of the forces exerted on this blade in the presence of a conductor in the cell, the blade spring coming to press against the corresponding ear so that the blade does not come to lean excessively against the insulating housing when it is requested by the driver.
- the main mechanical forces transverse to the bar are thus exerted essentially at the level of the ear and not at the level of the insulating casing which ensures a better reliability and an improved safety of use.
- leaf spring and the terminal block of the block according to the invention it is even possible for example, when implementing the Preferred features discussed below, to mount separately in the insulating housing the spring blade and the bar.
- the pre-assembly between the bar and the spring blade to form the subassembly is no longer required, it is possible to achieve a successive assembly within the housing of the spring blade and the bar.
- the partial closure of the common area to the introducer duct and the reception housing is made possible by the fact that the spring blade is assembled regardless of the bar. It is thus made possible, firstly, to introduce the spring blade into the housing through the open portion of the housing and then, in a second step, to move the spring blade to accommodate a portion of this blade in the partially closed common area and finally, in a third time, to assemble the bar to maintain in position the spring blade thus disposed.
- the partially closed zone common to the introduction duct and the receiving housing thus makes it possible to ensure optimal guiding of the end portion of the cable towards the cell during its insertion thus preventing the end portion of the cable, in particular in the vicinity of the cell, to escape from the terminal block transversely to the main faces of this block.
- the presence of the pin facilitates the installation of the spring blade in the partially closed zone by acting as a support around which the spring blade pivots to be placed in position in the introduction conduit.
- the additional pin plays the role of stop pin to limit the movement of the first branch of the spring blade.
- the terminal block 1 shown in FIGS. 1 to 12 comprises an insulating housing 2, a conductive bar 3 and two spring blades 4.
- the insulating casing 2 is made of molded plastic and has two main faces 5 and 6 connected to each other by a front lateral face 7, a rear lateral face 8, an upper face 9 and a lower face 10.
- the face 6 is completely obscured by a partition 22 while the face 5 is partially open.
- This housing comprises a latching lug 15, a latching lug 16 to an ⁇ rail, two cable introduction ducts 32, two operating ducts 33 and a receiving housing 39 (FIG. 3) of the bar 3 and leaf springs 4.
- the tabs 15 and 16 are located on the side of the face 8. Between these tabs extends a slot 17 formed inside the housing 2 and opening at the face 8.
- the hooking lug 15 has two identical portions 19 on either side of the slot 17, each portion presenting opposite the leg engaging a recess 20 adapted to receive as will be seen hereinafter a wing of a rail in ⁇ .
- the latching lug 16 has three partitions 25, 26 and 27 extending substantially transversely to the face 8.
- the partition 25 closest to the latching lug is separated by the slot 17 in two identical portions 18.
- Each portion 18 has a tooth 24 projecting towards the hooking lug 15.
- the housing also comprises between the legs 15 and 16 two partitions 21 on either side of the slot 17 extending parallel to the faces 5 and 6 of the partition portions 19.
- the ducts 32 (FIGS. 7 and 8) are delimited by two concave surfaces 47 and by the surface of a partition 48 located on the side of the face 6 and having a shoulder 48 '.
- the conduits 32 open on the face 7 through an opening 45 and on the face 5 through an opening 43.
- the opening 43 has two parallel edges 43 'in the direction of insertion of the cable and a curved edge 43 ".
- Each duct 32 is closed at the main faces by two triangular partitions 34 projecting parallel to the faces 5 and 6 towards the inside of the housing.
- One of these partitions 34 is located at the partially open face 5 and the other against the wall 22 closing the face 6 of the terminal block ( Figure 9) locally forming an extra thickness.
- the partition 34 located on the side of the face 6 is extended by a corner 42 ( Figure 9).
- the conduits 33 have a rectangular section and open only on the face 7 through an opening 46.
- the receiving housing 39 of the bar 3 and the spring blades 4 is partially delimited by a pair of closed-contour ribs 30 and a pair of closed-contour ribs 31 (FIG. 3).
- the zone of the housing 39 adapted to receive the bar is partially delimited by the rib sections 30 ", 31"'and the lower edge in FIG. 3 of the partitions 34 while each zone of the housing 39 adapted to receive a leaf spring 4 is partially delimited by the rib sections 30 ', 31', 31 "(FIG. 4) and comprises the space 44 (FIG. 7) situated between the two corresponding partitions 34.
- each zone of the receiving housing 39 adapted to receive a leaf spring 4 is a cylindrical pin 40 and an oblong pin 41.
- the space 44 located between two partitions 34 is common to the corresponding conduit 32 and the housing 39.
- the receiving housing 39 is thus, at each end, partially obscured on the face 5 by a partition 34.
- the casing is molded using three drawers, one for each pair of ducts 32, 33 and a third to form the slot 17.
- the bar 3 comprises a central step 50 (FIG. 7) and, on each side of the central step, a lateral step 51, each lateral step being connected to the central step by a riser 52 at right angles to the central step 50 and lateral steps 51 so that each step 51 forms with its riser 52 an L-shaped portion.
- the side steps 51 are located at the same level relative to each other so that the bar has a podium profile.
- the central step 50 has at its center a single orifice 63 while each side step 51 is provided with a cell 54 delimited by the surfaces of a stamped cage 55 projecting from the opposite side to the central step 50.
- the spring blades 4 shown in FIGS. 1 to 10 have an asymmetrical V-shaped profile, each leaf spring being formed by a large straight branch 58 and a small straight branch 59 connected to one another at one end by a curved section 60.
- Each of the branches 58 and 59 has, at about mid-length, a width change, with their width being smaller between their free end and the width changing zone.
- This assembly consists first of all in arranging each leaf spring 4 in the receiving housing 39.
- the curved section 60 of each leaf spring 4 is arranged around the pin 40 in the space in the vicinity of this piece the opposite side to the pin 41 ( Figure 3).
- the large branch 58 then takes place between the pins 40, 41 corresponding and the corresponding partitions 34 while the small branch 59 takes place between the pins 40, 41 corresponding and the corresponding rib 30 '( Figure 3).
- the next step is to rotate each leaf spring 4 around the corresponding pin 40, parallel to the faces 5 and 6, so that the end portion of the long section 58 of the spring blade is placed in the space 44 between the partitions 34 (Figure 4), this section being guided towards this space by the ramp formed by one of the surfaces of the wedge 42 ( Figure 9), to abut against the housing ( Figure 4).
- the end portion of the branch 58 is thus housed in the corresponding introduction conduit 32.
- the blade thus disposed releases the area of the housing 39 adapted to accommodate the bar 3 so that it is now possible to introduce this bar in the housing.
- the central step 50 is disposed between the sections of ribs 30 "and 31 '" of the insulating housing while the end portions of the side steps 51 are housed under the partitions 34 ( Figure 5).
- the conduit 32 For each cage 55, the conduit 32 thus opens into the cell 54. A wall 56 of the cage 55 is then disposed under the end edge 61 of the branch 58 of the corresponding spring blade while the end portion of the branch 59 looks, on the opposite side to the branch 58, the riser 52 ( Figures 5 and 6).
- the last operation consists, using a tool or a rigid core cable through the conduit 32 or 33, to come to exert pressure against the branch 58 to abut the branch 59 against the riser 52 and thus bend the branch 58 to cross a hard point relative to the bar 3 so as to have the end edge 61 of this branch in the cell 54, against the surface 57 of the wall 56 of the cage 55 ( Figure 7).
- Such tips are for example used in conjunction with cables whose conductive core is formed of flexible strands to facilitate the introduction of conductors in the terminal block without the risk of folding the flexible strands.
- tips (70) comprise a hollow and conductive hollow cylindrical element 71 crimped around the stripped end of a conductor (not shown) and an insulating plastic casing 72.
- the first step is to penetrate the tip 70 through the conduit 32 in which it must be inserted in order to constrain the leaf spring by pressing the leg 58 to separate the end edge 61 ( Figures 6 and 7). the surface 57 to allow this element to pass between this edge 61 and the wall 56.
- the wiring end-piece 70 is thus introduced into the duct 32, the driving movement of the cable continuing for example until the end of the element 71 comes into abutment against the ridge section 31 'or until that the envelope 72 abuts at the level of the face 5 against the curved edge 43 'of the partition 34 or, at the level of the face 6, against the shoulder 48' of the partition 48.
- this wall forms for the element 71 a seat against which it is held by the spring blade 4 which plate against this surface. If this element once installed in the terminal block 1 tends to be removed from the block, that is to say if it is subjected to a force directed in a direction contrary to the direction of insertion, this element will tend to bring with it the branch 58, which will bend and thus wedge against the wall 56, which will prohibit the removal of this element.
- the operator For the withdrawal of the tip 70, the operator makes it through the conduit 33 corresponding to the duct 32 into which is inserted the nozzle 70, a tool (for example the flat end 73 of the screwdriver shown in FIG. of constrain the spring blade, until the branch 58 eventually abuts against the oblong pin 41, to release the element 71 and allow to extract the tip 70.
- a tool for example the flat end 73 of the screwdriver shown in FIG. of constrain the spring blade, until the branch 58 eventually abuts against the oblong pin 41, to release the element 71 and allow to extract the tip 70.
- the contact foot 80 to be assembled at the terminal block 1 will now be described with reference to FIGS. 10 to 14 if it is desired to form a terminal block electrically connecting one or two cables not only to each other but also to the conducting rail. in ⁇ (block for protective conductors).
- Such terminal blocks are generally identified by their color, the insulating housing of these blocks being tinted in two colors, one yellow and the other green (green / yellow block).
- the contact foot 80 illustrated in FIGS. 13 and 14 is made of conductive metal and is formed in one piece. It comprises a central body 81, a hooking tab 82, and a locking tab 83.
- the central body 81 has two generally rectangular portions 84 and 85, the portion 84 being wider than the portion 85.
- the portion 84 attaches the tabs 82 and 83 to the rectangular portion 85.
- This portion 85 has at its top two protruding teeth 86 on the side opposite the portion 84 while in the portion 84 is formed a rectangular window 87.
- the locking tab 83 has at its distal end a rigid notch 88 and an elongated and flexible narrow arm 91 attaching the notch 88 to the body 81.
- This notch 88 has a tooth 90 and a finger 77 having a ramp surface 89 and a boss 78.
- the arm 91 is of constant width except for its end portions which are slightly curved, each respectively reaching, by flaring, the notch 88 and the body 81.
- the hooking lug 82 comprises a hook 92 adapted to receive, as will be seen below one of the wings of a rail in ⁇ and an elongated and flexible narrow arm 76 joining the hook 92 to the body 81 by attaching to the hook 92 on the opposite side of the hook 81 to the body relative to the notch 93.
- the arm 76 comprises a C-section 94, here more precisely in a half-circle, in the hollow of which is housed the hook 92 and an inclined straight section 95.
- the C-section 94 is connected at one end to the hook 92 and at the other end to the straight inclined section 95 itself connected by its opposite end to the body 81 so that the arm 76 has a profile in J.
- the hook 92 comprises a rigid block 79 in which is formed a notch V 93.
- the leg of the block 79 defining the notch V located on the side of the hook opposite the body 81 relative to the notch 93 is attached to the arm 94 of the leg 82.
- the contact foot is introduced into the junction block on the side of the face 8 by the slot 17 extending from the latching lug 15 to the latching lug 16 of the insulating housing 2.
- the body 81 enters the insulating housing between the rib portions 31 "", the portion 85 first until a tooth 35 ( Figure 11) of the insulating housing, projecting from the partition 21 located on the side of the face 5 towards the inside of the housing, is snapped into the square-shaped orifice 87 of the body 81, the slots 23 formed in this partition 21 ensuring an elastic deformation of the tooth 35.
- the hook 92 of the hooking tab 82 of the contact foot is housed between the two partition portions 19 of the tab 15, so that the notch 93 is between the two recesses 20 while the notch 88 of the engagement tab 83 is housed between the two partition portions 18 between the teeth 24 (FIG. 11).
- a crimping operation is performed using a tool (not shown) adapted to be introduced into the housing on the side of the face 7 by two chimneys 37 ( Figure 10) formed in the insulating housing on each side of a central wall 38 and opening on the face 7 to exert pressure against the surfaces 96 of the teeth 86 to move away from one another as shown in Figure 10.
- This crimping makes it possible to guarantee the permanent mechanical maintenance of the contact foot 80 with the bar 3 and improves, by increasing the clamping pressure with this bar, the quality of the electrical contact between this foot and this bar.
- the engagement of the terminal block is here described in the case where it has a contact foot.
- the interlocking characteristics of the insulating housing alone remain the same when the terminal block does not have such a contact foot (no electrical connection to the rail).
- the conductive support rail 65 shown in Figures 15 to 18 is a profile rail commonly used to install terminal blocks. It has a central section 66 and two branches 67 folded at right angles, the ends of the branches 67 being bent at right angles outwards to form two lateral wings 68, the section of the profiled rail thus having a shape in ⁇ (reversed on the figures).
- This rail can be fixed (for example by screwing the section 66) to the uprights of an electrical cabinet or against a wall support, the central section 66 and the wings 68 then being in a vertical plane (rotated 90 ° with respect to the figures 17 and 18).
- the interlocking operation consists in hooking the terminal block against one of the wings 68 of the ⁇ rail as illustrated in FIG. 15 by introducing this wing into the notch 93 of the hooking tab 82.
- the contact foot shown without the insulating housing in Figure 17 for the sake of clarity
- the recess 20 of the attachment lug 15 of the insulating housing Figure 15
- the next step is to simultaneously engage the engagement tab 83 (Figure 18) of the contact foot and the latching tab 16 ( Figure 16) of the insulating housing on the other flange 68 of the ⁇ rail.
- the operator presses the terminal block against the face 7 towards the rail in ⁇ and preferably, to take advantage of the leverage, the farthest side of the tab 15.
- This action causes a deformation of the arm 82 until the engagement tab 83 is supported by the ramp 89 of the finger 77 against the upper edge of the wing 68 corresponding.
- the ramp 89 thus guides the foot 80 which deforms until the ramp passes under the wing 68, the tooth 90 abuts against this wing ( Figure 18).
- the boss 78 located at the end of the ramp 89, under the tooth 90 ensures the stable maintenance of the contact foot rail, preventing any risk of inadvertent disengagement.
- the long length of the sections 94 and 95 ensures optimum flexibility for the arm 76 which deforms throughout this operation.
- a connection to the ⁇ rail is made in the same way except that such a terminal block is engaged to the rail only by the legs of the rail. hooking and engagement of the insulating housing. Such an operation then in this case not to provide an electrical connection but only to ensure mechanical support of the terminal block to the rail.
- the rail 165 shown in Figure 19 and the rail 265 shown in Figure 20 differ from the rail 65 shown in Figure 17 in particular by the height and thickness of their branches and their wings.
- the V-shaped notch 93 and in particular the distance to the bottom of the notch separating the two branches of the V is adapted to cooperate with the three types of rail illustrated, that the wings of these rails is of constant thickness ( rail 65) or that this thickness decreases towards the edge of the wings (rails 165 and 265).
- This partition 97 ( Figures 21 to 23) has two notches 99, two pins 98 and two ribs 96 projecting from the same side of the partition 97.
- Each notch 99 has a contour similar to that of the opening 43 of the conduit 32 corresponding. Each notch is thus delimited by two straight edges 99 'parallel to the direction of insertion of the cable and an edge 99 "transverse to this direction joining the straight edges 99'.
- This partition is nested at the junction block 1 by disposing the partition 97 facing the face 5 of the junction block 1 so that the lugs 98 of this partition are engaged in mortises 29 that presents the insulating housing 1 of the block of junction ( Figure 22), the rib 96 then being housed within the rib 31 to increase the length of the vanishing lines of the terminal block.
- each duct 32 of the terminal block has an opening 43 through which a wiring end can project laterally, in particular if the largest diameter of this endpiece is greater than the distance separating the main faces 5 and 6 (also called step of the terminal block), neglecting the thickness of the partition 48 closing the conduit 32 at the face 6.
- the thickness of the partition 48 is relatively small so that it is considered that it is a negligible magnitude before the pitch of the terminal block.
- larger diameter is used here to mean that of the diameters of the element of the endpiece which has the largest dimension, for example, in the case of the endpiece 70, the diameter of the envelope 72.
- the convex faces 47, the partition 48 and the shoulder 48 'and the edges 43' and 43 are dimensioned together with the partition 97 to ensure that, even for a wiring end having a larger diameter equal to the diameter. maximum that can be received in the conduit, the portion of this nozzle projecting from the block through the opening 43 of the conduit can be fully housed in the opening 99 of the partition 97 without protruding from this partition.
- the junction block has a pitch of 5 mm and the ducts 32 are adapted to receive wiring nozzles of greater maximum diameter equal to 6 mm, while the partition 97 has a thickness of 1 mm. so as to accommodate in each aperture 99 the portions of the end pieces projecting from the block up to a maximum diameter of 6 mm (ie a maximum lateral projection of about 1 mm with respect to the terminal block).
- a tip of larger diameter greater than 6 mm can not be introduced into the ducts 32, these ducts being shaped so that such an endpiece abuts against the edges of the opening 45 and thus prevent its insertion.
- FIGS. 24 to 28 Another embodiment of the terminal block is shown in FIGS. 24 to 28.
- the pins 140 and 141 are joined, the end of the pin 140 forming a finer finger than the pin 40 to reduce the bending force and ensure a better fit of the curved section 160 within the housing 102.
- the rib portion 131 "' has a recess 136 facing the corresponding rib portion 130" and is thus adapted to cooperate snap-in as will be seen hereinafter with the bar 103.
- the partition 122 is not located here at the face 106 but midway between the faces 105 and 106 (if not under the rib section 131 "') in order to lengthen the lines as much as possible. leakage between conductive elements.
- the bar 103 has two bosses 149.
- each leaf spring is disposed in the housing ( Figure 24) and rotated ( Figure 25) to make room for the bar 103 ( Figure 26).
- the bosses 149 of this bar cooperate snap with the recesses 136 to enhance the mechanical retention of the bar 103 to the housing 102 ( Figure 26).
- the offset located under the rib portion 131 "'of the wall 122 at the face 106 allows this section to be sufficiently deformable and elastic to snap the bar.
- the branch 158 is then flexed to pass a hard point relative to the bar so that it comes opposite the wall 156 of the cage 155 ( Figure 27).
- the bar 103 of the block 101 has a window 163 so that this block can receive the contact foot 80 ( Figure 28).
- the strip 203 is rectilinear and has a central section 250, each end of which is connected to the end of a section 252. provided with an ear 253, one face forms, as will be seen hereinafter, a stop for a corresponding leaf spring 204.
- the end of each section 252 opposite to that connected to the section 250 is connected to one end of a section 251 provided with a cell 254.
- the sections 252 are connected in the extension of the neighboring section 251 and the central section 250.
- Each lug 253 is inclined towards the corresponding cell 254, so that the ear forms with the rest of the section 252 closest to the cell 254 an acute angle.
- the insulating housing 202 has under the rib 230 a finger 264 adapted to cooperate with the section 250 and the corresponding section 252.
- the branch 259 comprises a straight section 269 and a straight section 262 connected to each other so that the branch 259 has a bent shape, with the section 262 which is turned on the opposite side at branch 258 and looking at the face of the ear 253 closest to the cell.
- FIGS. 30 to 33 The various assembly steps illustrated in FIGS. 30 to 33 are similar to those described in the preceding embodiments except that in this case, the bar 203 is inserted between the fingers 264 and the ribs 231 "'. 253 ear along this finger coming to be placed next to it) and that it is the section 262 which abuts against the ear 253 ( Figure 33).
- the branch 259 is here bent so as to cooperate effectively with the inclined lug 253 corresponding, the section 262 being disposed opposite it.
- each lug 253 towards the corresponding cell 254 makes it possible to take back part of the forces exerted on the casing transversely to the lug by means of the leaf spring 204 when a conductor is inserted into the lug. alveolus.
- the section 262 of the spring blade is pressed against the corresponding ear which thus takes up part of the forces so that the curved section 260 of this blade is less biased to move towards the face 207 and not therefore does not exert excessive pressure against the casing insulation at the wall of this housing located opposite the pin 240 relative to this section 260.
- each lug 253 is connected to the remainder of the section 252 at a right angle and / or the force to be exerted to cross the hard point for each leaf spring to be arranged opposite the seat of the cell corresponding is very low or non-existent depending on the set of non-reproducible assembly of the different elements together (housing, blades, bar).
- the terminal block is designed to receive not two but at least three conductors arranged on one or more stages of the terminal block.
