Description

La présente invention se rapporte àune borne de connexion élastique pour appareil d'interruption ou de jonction électrique, la borne comprenant une pièce conductrice dotée àune extrémité d'une plage d'appui pour une boucle élastique destinée àserrer au moins un câble.The present invention relates to an elastic connection terminal for an interruption device or electrical junction, the terminal comprising a conductive part provided with a end of a bearing surface for an elastic loop intended to tighten at least one cable.

Dans les bornes de ce genre, il est généralement prévu une boucle élastique présentant une branche d'appui, une branche de serrage et une partie cintrée reliant les branches d'appui et de serrage. La branche d'appui est appliquée sur le recto de la plage d'appui pour faire contact avec la pièce conductrice, tandis que la branche de serrage est munie d'une fenêtre agencée pour permettre le coincement d'un câble introduit par une ouverture d'un boítier ou d'un capot de l'appareil. Plus précisément, le coincement du câble s'effectue entre un bord mobile de la fenêtre et une région de connexion située au verso de la plage d'appui. ; le desserrage du câble s'effectue par une pression exercée sur la partie cintrée de la boucle au moyen d'un outil ou d'une broche d'interconnexion.In terminals of this kind, there is generally provided an elastic loop having a supporting branch, a clamping branch and a curved part connecting the branches support and clamping. The support branch is applied to the front of the support area to make contact with the conductive part, while the clamping branch is provided with a window arranged to allow the jamming of a cable introduced by an opening of a housing or cover of the device. More precisely, the cable is trapped between a movable edge of the window and a connection region located on the back of the support surface. ; the cable is loosened by pressure exerted on the curved part of the loop by means of an interconnection tool or pin.

Une telle borne, décrite dans le document EP 1 052 729, comporte une pièce auxiliaire qui sert àlimiter la flexion de la boucle et qui est apte àformer une butée pour le câble. L'introduction du câble dans cette borne s'effectue avec un guidage qui peut être amélioré. D'autre part, les efforts du câble àl'insertion se traduisent par un flottement de la pièce auxiliaire, voire des risques de rupture de celle-ci.Such a terminal, described in document EP 1 052 729, comprises an auxiliary part which serves to limit the bending of the loop and which is capable of forming a stop for the cable. The introduction cable in this terminal is carried out with a guide which can be improved. Else apart, the forces of the cable on insertion result in a floating of the auxiliary part, or even the risk of it breaking.

L'invention a pour but d'améliorer dans une borne du type décrit le guidage, le maintien et l'isolement du câble, tout en assurant une tenue satisfaisante de la boucle élastique et une bonne cohésion de l'assemblage de ses pièces composantes.The object of the invention is to improve in a terminal of the type described the guidance, the maintenance and cable insulation, while ensuring satisfactory resistance of the elastic loop and good cohesion of the assembly of its component parts.

Selon l'invention, la pièce auxiliaire est adossée au verso de la plage d'appui et présente au moins un élément d'accrochage en prise avec la plage d'appui, par exemple dans sa région de connexion. Il en résulte une bonne tenue de la borne dans l'appareil, en particulier sous l'effet des efforts ou chocs subis lors des manoeuvres du câble et de l'outil. According to the invention, the auxiliary part is attached to the back of the support surface and present at the less a hooking element engaged with the support surface, for example in its region of connection. This results in good behavior of the terminal in the device, in particular under the effect of the forces or shocks undergone during the operations of the cable and the tool.

La pièce auxiliaire offre de préférence des joues de guidage et d'isolement du câble, ces joues s'étendant jusqu'au voisinage de la région de connexion de la pièce conductrice et présentant une pente de guidage adaptée àla forme incurvée de la branche de serrage de la boucle. Les éléments d'accrochage peuvent être des tenons prévus aux extrémités des joues de guidage qui sont situées vers la branche de serrage de la boucle élastique.The auxiliary part preferably offers cheeks for guiding and isolating the cable, these cheeks extending to the vicinity of the connection region of the conductive part and having a guide slope adapted to the curved shape of the clamping branch of the loop. The hooking elements may be studs provided at the ends of the guide cheeks which are located towards the tightening branch of the elastic loop.

On peut avantageusement doter la pièce conductrice d'une fente et le pied de la pièce auxiliaire d'une languette, la languette traversant la fente pour faire saillie du côté du recto de la plage d'appui. La languette détermine ainsi une plage de garde ou de butée qui limite le glissement de la boucle. La languette peut en outre être munie d'un élément d'encliquetage ou analogue qui contribue àmaintenir la pièce auxiliaire assemblée àla pièce conductrice.It is advantageous to provide the conductive part with a slot and the foot of the auxiliary part a tongue, the tongue crossing the slot to project from the side of the front of the support range. The tongue thus determines a range of guard or stop which limits the sliding of the loop. The tongue can also be provided with a snap-in element or analog which contributes to maintain the auxiliary part assembled to the conductive part.

Une pièce de protection indépendante de la pièce auxiliaire peut avantageusement être logée dans la boucle, en étant agencée de façon en soi connue pour limiter la flexion de la boucle.A protective part independent of the auxiliary part can advantageously be accommodated in the loop, being arranged in a manner known per se to limit the bending of the loop.

La description détaillée qui suit se réfère àun mode de réalisation de l'invention donné àtitre d'exemple non limitatif et représenté par les dessins annexés.The following detailed description refers to an embodiment of the invention given under non-limiting example and shown in the accompanying drawings.

La figure 1 représente schématiquement en vue de côté une borne selon l'invention.Figure 1 shows schematically in side view a terminal according to the invention.

La figure 2 est une vue similaire montrant la boucle élastique en position de desserrage.Figure 2 is a similar view showing the elastic loop in the released position.

La figure 3 représente en perspective avant une borne selon l'invention.Figure 3 shows in perspective before a terminal according to the invention.

La figure 4 est une vue partielle d'une borne double, similaire àcelle de la figure 3, en perspective arrière.Figure 4 is a partial view of a double terminal, similar to that of Figure 3, in perspective back.

La figure 5 montre en perspective la pièce auxiliaire de la borne de la figure 4.FIG. 5 shows in perspective the auxiliary part of the terminal of FIG. 4.

La borne de connexion élastique 10 illustrée sur les figures est associée ou intégrée àun appareil d'interruption ou dispositif de jonction électrique 11 tel qu'un contacteur, disjoncteur, bloc de jonction, bornier, ou autre dispositif électrique analogue impliquant une connexion rapide. La borne 10 est placée dans un logement approprié 12 du corps ou boítier 13 de l'appareil.The elastic connection terminal 10 illustrated in the figures is associated or integrated with a interruption device or electrical junction device 11 such as a contactor, circuit breaker, terminal block, terminal block, or other similar electrical device involving connection fast. Terminal 10 is placed in a suitable housing 12 in the body or case 13 of the device.

La borne comprend une boucle élastique 20 de type connu montée sur une pièce conductrice 14 propre àl'appareil 11, la pièce conductrice étant par exemple emboítée ou fixée dans le boítier 13 de l'appareil. Dans le cas présent, la pièce 14 est fixée àune plage de connexion 15 par une vis 15a (illustrée par son axe figure 1), la pièce 14 et/ou la plage 15 étant solidarisées avec le boítier par tout moyen. Le logement 12 communique avec l'extérieur du boítier 13 par une ouverture 16 en forme d'entonnoir pour l'introduction d'un câble conducteur dénudé en bout, et par une ouverture 17 d'introduction d'un outil de desserrage ou d'une broche conductrice de connexion.The terminal comprises an elastic loop 20 of known type mounted on a conductive part 14 specific to the device 11, the conductive part being for example fitted or fixed in the housing 13 of the device. In the present case, the part 14 is fixed at a range of connection 15 by a screw 15a (illustrated by its axis in figure 1), the part 14 and / or the track 15 being secured to the housing by any means. Housing 12 communicates with the outside of the housing 13 by an opening 16 in the form of a funnel for the introduction of a cable conductor stripped at the end, and by an opening 17 for introducing a loosening tool or a connecting lead.

La boucle 20 offre une branche d'appui 21 et une branche de serrage 22 reliées entre elles par une partie cintrée 23. La boucle 20 est disposée sur une plage fixe d'appui 18 de la pièce conductrice 14 qui offre un recto 18a et un verso 18b. Plus en détail, la branche d'appui 21 est appliquée sur le recto 18a, tandis que la branche de serrage 22 est munie d'une fenêtre 24 définie latéralement par deux segments 25 et, vers l'extrémité libre de la branche 22, par une languette d'extrémité 26 afin de présenter en regard du verso 18b une arête 27 de serrage (voir figure 3).The loop 20 offers a support branch 21 and a clamping branch 22 connected to each other by a curved portion 23. The loop 20 is disposed on a fixed bearing surface 18 of the conductive part 14 which offers a front 18a and a back 18b. In more detail, the support branch 21 is applied to the front 18a, while the clamping branch 22 is provided with a window 24 defined laterally by two segments 25 and, towards the free end of the branch 22, by an end tab 26 in order to present opposite edge 18b an edge 27 tightening (see figure 3).

Une pièce auxiliaire 30, apte aux fonctions de guidage, de butée et d'isolement du câble, est appliquée contre le verso 18b de la plage d'appui 18. La pièce auxiliaire 30 présente des joues 31 de guidage de câble, un fond de butée 32 pour le câble et une paroi arrière 33. Elle présente aussi vers le haut , en saillie vers l'avant, des tenons 34 ou éléments similaires d'accrochage qui s'engagent sur la pièce conductrice 14, ainsi que vers le bas au moins une languette 35 pénétrant dans une fente 19 de la pièce 18. Les tenons et la languette positionnent et maintiennent la pièce auxiliaire 30 sur la pièce 14. La languette 35 sert de butée basse pour la boucle élastique, et est pourvue d'un élément d'encliquetage (ou d'emboítement) 36 qui permet de maintenir la pièce 30 assemblée àla plage d'appui 18. A l'arrière de la pièce 30 sont prévues des butées 38, sous forme de nervures ou de doigts, coopérant avec une face 12b du logement 12. On observera que les joues 31 ménagent avec le fond 32 et la paroi arrière 33 un logement individualisé 37 pour l'extrémité dénudée du câble, assurant notamment les fonctions de guidage et d'isolement interphases lorsque plusieurs fils sont connectés dans des bornes voisines correspondant àdifférentes phases (voir par exemple figures 4 et 5). Cet espace protège d'autre part la borne électrique contre des effets fâcheux dus àl'introduction de matières polluantes.An auxiliary part 30, suitable for guiding, abutment and cable isolation functions, is applied against the back 18b of the support surface 18. The auxiliary part 30 has cable guide cheeks 31, a stop bottom 32 for the cable and a rear wall 33. It also has upward, projecting forward, studs 34 or the like hooking which engage on the conductive part 14, as well as at least down a tongue 35 penetrating into a slot 19 of the part 18. The tenons and the tongue position and hold the auxiliary part 30 on the part 14. The tongue 35 serves as a stop low for the elastic loop, and is provided with a latching (or interlocking) element 36 which keeps the part 30 assembled to the support surface 18. At the rear of the part 30 are provided with stops 38, in the form of ribs or fingers, cooperating with a face 12b of the housing 12. It will be observed that the cheeks 31 spare with the bottom 32 and the rear wall 33 an individualized housing 37 for the stripped end of the cable, ensuring especially the interphase guidance and isolation functions when several wires are connected in neighboring terminals corresponding to different phases (see par example Figures 4 and 5). This space also protects the electrical terminal against effects annoying due to the introduction of pollutants.

Les joues 31 de la pièce auxiliaire 30 sont appliquées par des faces rectilignes sur la face plane correspondante du verso 18b de la pièce 14 jusqu'au voisinage de la branche de serrage 22 de la boucle. Elles comportent juste en dessous de cette branche 22 (figures 1-4) des éléments d'accrochage ou d'encliquetage. Dans le cas présent, il s'agit de tenons d'accrochage 34 engagés dans des encoches 18d situées àla partie haute de la pièce 14, près de l'extrémité de la plage d'appui 18 dans sa région de connexion 18c. Des éléments coopérants de forme différente, mais ayant une même fonction d'accrochage ou d'encliquetage, peuvent bien sûr être substitués aux tenons 34 et encoches 18d. Dans le prolongement des tenons 34, les joues 31 ont une forme, par exemple àpente descendante, adaptée àla forme pentue ou incurvée de la branche 22 et àson mouvement pivotant, pour en faciliter le guidage. La languette 35 s'étend orthogonalement au sens d'introduction du câble et traverse la fente 19 prévue dans la région 18e de la plage 18 qui est opposée àsa région de connexion 18c (voir figure 4).The cheeks 31 of the auxiliary part 30 are applied by rectilinear faces to the face corresponding plane of the back 18b of the part 14 to the vicinity of the clamping branch 22 of the loop. They include just below this branch 22 (Figures 1-4) hooking or snap-fastening elements. In this case, these are latching studs 34 engaged in 18d notches located at the top of room 14, near from the end of the support surface 18 in its connection region 18c. Cooperating elements differently shaped, but having the same hooking or snap-fastening function, can of course be substituted for studs 34 and notches 18d. In the prolongation studs 34, the cheeks 31 have a shape, for example with a falling slope, adapted the sloping or curved shape of the branch 22 and its pivoting movement, to facilitate guidance. The tongue 35 extends orthogonally to the direction of introduction of the cable and crosses the slot 19 provided in the region 18e of the range 18 which is opposite to its region of connection 18c (see figure 4).

Le logement 37 déterminé par le fond 32, les joues 31 et la paroi 33 sert àguider l'extrémité du câble dès sa sortie de l'entonnoir et àloger l'extrémité du câble. L'élément d'emboítement ou d'encliquetage 36 assure avec les tenons 34 un assemblage rigide et résistant de la pièce auxiliaire 30 avec la pièce conductrice 14. On notera qu'une pièce de protection 40, indépendante de la pièce auxiliaire 30, est disposée àl'intérieur de la boucle pour limiter l'écrasement de celle-ci.The housing 37 determined by the bottom 32, the cheeks 31 and the wall 33 serves to guide the end of the cable as soon as it comes out of the funnel and house the end of the cable. The interlocking element or snap-fastening 36 ensures with the studs 34 a rigid and resistant assembly of the auxiliary part 30 with the conductive part 14. It will be noted that a protective part 40, independent of the auxiliary part 30, is arranged inside the loop to limit overwriting it.

La borne décrite s'utilise de la manière suivante. Un outil ou une broche de manoeuvre est engagé dans l'ouverture 17 pour presser l'extrados de la partie cintrée 23 et mettre ainsi la boucle élastique en position desserrée (en traits pleins sur la figure 2). Ce faisant, les bords de la languette 26 et les segments latéraux 25 de la branche de serrage 22 glissent sur les pentes des joues de guidage 31. Un câble par exemple multibrins est alors présenté devant l'ouverture 16 et engagé dans celle-ci, la pente de l'entonnoir amenant l'extrémité dénudée du câble contre le verso 18b de la plage d'appui 18, dans sa région de connexion 18c. L'extrémité du câble est guidée d'une part par le verso 18b de la plage 18, d'autre part latéralement par les joues 31, jusqu'àêtre arrêté par le fond 32. On peut remarquer que le câble introduit dans son logement 37 reste isolé d'un câble inséré dans un logement 37 adjacent par une joue intermédiaire 31 formant une cloison.The terminal described is used as follows. An operating tool or spindle is engaged in the opening 17 to press the upper surface of the curved part 23 and thus put the elastic loop in the released position (in solid lines in Figure 2). In doing so, the edges of the tongue 26 and the lateral segments 25 of the clamping branch 22 slide on the slopes of the guide cheeks 31. A cable for example multi-strand is then presented in front the opening 16 and engaged therein, the slope of the funnel bringing the stripped end of the cable against the back 18b of the support pad 18, in its connection region 18c. The end of the cable is guided on the one hand by the back 18b of the track 18, on the other hand laterally by the cheeks 31, until being stopped by the bottom 32. It can be noted that the cable inserted into its housing 37 remains isolated from a cable inserted in an adjacent housing 37 by an intermediate cheek 31 forming a partition.

Les efforts de poussée subis par la pièce auxiliaire 30 àl'introduction du câble sont repris en haut par la partie supérieure (sur les figures) de la pièce 14 au moyen des tenons 34 engagés dans les encoches 18d et en bas par la languette 35 coopérant avec la fente 19.
