Description

L'invention concerne une pince à sertir notamment pour sertir les manchons, isolés ou non, destinés au raccordement des câbles électriques.The invention relates to a crimping tool especially for crimping sleeves, insulated or not, intended for the connection of electric cables.

Les pinces connues, notamment celle décrite dans le document FR-A-1 276 554, comportent habituellement deux mâchoires qui restent ouvertes en position de repos et se rapprochent par rotation pour le sertissage. Dans la position ouverte des mâchoires, le manchon à sertir n'est pas maintenu ; il est donc nécessaire de le positionner et de le maintenir à la main jusqu'à ce qu'il soit serré par les mâchoires.Known pliers, in particular that described in document FR-A-1 276 554, usually have two jaws which remain open in the rest position and move together by rotation for crimping. In the open position of the jaws, the crimp sleeve is not held; it is therefore necessary to position and hold it by hand until it is clamped by the jaws.

L'invention a pour but de réaliser une pince à sertir comportant des mâchoires fermées en position repos de façon à permettre de positionner le manchon à sertir dans la pince avant le sertissage, libérant une main de l'opérateur qui peut ainsi tenir la pince d'une seule main. Plus particulièrement cette pince destinée à sertir un manchon sur un câble, comporte classiquement des mâchoires accouplées l'une à l'autre de manière que l'une soit mobile par rapport à l'autre, une came entraînée par une roue à rochet actionnant un dispositif à genouillère agissant lui-même sur la mâchoire mobile dans le sens de la fermeture, un cliquet monté sur la poignée mobile de façon à entraîner la roue à rochet pas-à-pas lors des mouvements de rapprochement de la poignée mobile.The object of the invention is to produce a crimping pliers comprising jaws closed in the rest position so as to allow the crimping sleeve to be positioned in the pliers before crimping, freeing a hand of the operator who can thus hold the pliers. 'one hand. More particularly, this pliers intended to crimp a sleeve on a cable, conventionally comprises jaws coupled to one another so that one is movable relative to the other, a cam driven by a ratchet wheel actuating a toggle device acting itself on the movable jaw in the closing direction, a pawl mounted on the movable handle so as to drive the ratchet wheel step by step during movements of the movable handle.

Selon une caractéristique de l'invention la pince à sertir comporte une matrice mobile coulissant dans des rainures rectilignes fixes vers la mâchoire fixe, à la fermeture, en vue d'assurer le sertissage, le dispositif à genouillère faisant tourner la mâchoire mobile qui pousse la matrice mobile, une liaison entre matrice et mâchoire assurant le retrait de la matrice mobile lors de l'ouverture de la pince. De plus en position de repos, la mâchoire mobile est fermée sous l'action d'un ressort agissant sur le dispositif à genouillère, une gâchette permettant d'appuyer sur le dispositif à genouillère en s'opposant au ressort pour assurer un écartement de la mâchoire mobile qui permet l'introduction du manchon à sertir entre les mâchoires, le relâchement de la gâchette assurant le maintien du manchon en position de sertissage dans la pince.According to one characteristic of the invention, the crimping tool comprises a movable matrix sliding in fixed rectilinear grooves towards the fixed jaw, on closing, in order to ensure crimping, the toggle device rotating the movable jaw which pushes the mobile matrix, a connection between matrix and jaw ensuring the removal of the mobile matrix when the clamp is opened. In addition, in the rest position, the movable jaw is closed under the action of a spring acting on the toggle device, a trigger making it possible to press the toggle device while opposing the spring to ensure a separation of the movable jaw which allows the insertion of the sleeve to be crimped between the jaws, the release of the trigger ensuring the maintenance of the sleeve in the crimping position in the pliers.

L'invention va être précisée par la description qui va suivre d'un mode préféré de réalisation de l'invention donné à titre d'exemple non limitatif, en référence au dessin annexé dans lequel :

  • La figure 1 est une vue en élévation d'une pince selon l'invention.
  • La figure 2 est une vue en coupe longitudinale selon la ligne II-II de la figure 1.
  • La figure 3 est une vue en coupe des mâchoires suivant la ligne Ill-lll de la figure 1.
  • La figure 4 est une coupe suivant la ligne IV de la figure 1.
  • La figure 5 est une coupe partielle suivant la ligne V de la figure 1.
  • La figure 6 est une coupe partielle suivant la ligne Vl de la figure 1.
The invention will be clarified by the description which follows of a preferred embodiment of the invention given by way of nonlimiting example, with reference to the appended drawing in which:
  • Figure 1 is an elevational view of a clamp according to the invention.
  • FIG. 2 is a view in longitudinal section along the line II-II of FIG. 1.
  • Figure 3 is a sectional view of the jaws along the line III-III of Figure 1.
  • Figure 4 is a section along line IV of Figure 1.
  • FIG. 5 is a partial section along the line V in FIG. 1.
  • FIG. 6 is a partial section along the line V1 in FIG. 1.

En se référant au dessin, la pince comporte une mâchoire fixe 11 et une mâchoire mobile 12 commandée par une poignée mobile 13. La mâchoire mobile 12, tournant autour d'un axe 12a, agit sur une matrice 14 à déplacement axial dans une rainure de la mâchoire fixe 11 et dans une rainure d'une pièce d'usure 10 fixée au boîtier de la pince. Ce déplacement est obtenu pour le sertissage axial d'un manchon (non représenté), à partir du déplacement de la poignée 13 par l'intermédiaire d'une came 15 solidaire d'une roue dentée 16, montée sur un axe 16a, à avance pas à pas par cliquet 17 monté sur un axe 17a de la poignée 13 et sollicité par un ressort 17b.Referring to the drawing, the clamp comprises a fixed jaw 11 and a movable jaw 12 controlled by a movable handle 13. The movable jaw 12, rotating around an axis 12a, acts on a matrix 14 with axial displacement in a groove of the fixed jaw 11 and in a groove of a wearing part 10 fixed to the housing of the clamp. This displacement is obtained for the axial crimping of a sleeve (not shown), from the displacement of the handle 13 by means of a cam 15 integral with a toothed wheel 16, mounted on an axis 16a, in advance step by step by ratchet 17 mounted on an axis 17a of the handle 13 and biased by a spring 17b.

Le manchon à sertir est maintenu dans la pince entre une matrice fixe 18 et la matrice mobile 14 ; le déclenchement d'une gâchette 19 permet de déplacer la mâchoire mobile 12 par action sur un ressort 25 accroché par un axe 25a à une extrémité 20b de la biellette 20 et par suite la matrice mobile 14 pour libérer le manchon. La gâchette 19 agit sur la biellette 20 qui déverrouille la mâchoire mobile en tendant le ressort 25. La pince comporte de préférence une came double 15 qui agit sur un même galet 21 d'une genouillère formée de deux biellettes 20 et 22. Il suffit d'un déplacement de 180° de la came pour réaliser l'opération de sertissage - un tour complet de 360° de la came permet de réaliser deux opérations de sertissage, ce qui réduit de moitié le nombre de manoeuvres de la poignée mobile.The crimp sleeve is held in the pliers between a fixed die 18 and the movable die 14; the triggering of a trigger 19 makes it possible to move the movable jaw 12 by action on a spring 25 hooked by an axis 25a at one end 20b of the link 20 and consequently the movable matrix 14 to release the sleeve. The trigger 19 acts on the link 20 which unlocks the movable jaw by tensioning the spring 25. The clamp preferably comprises a double cam 15 which acts on the same roller 21 of a toggle formed by two links 20 and 22. It suffices to '' a 180 ° movement of the cam to perform the crimping operation - a full 360 ° revolution of the cam allows two crimping operations to be carried out, which halves the number of operations of the movable handle.

La came double 15 agit sur le galet mobile 21 solidaire des deux biellettes 20, 22 dont l'une 22 pivote sur un axe fixe 22a et l'autre 20 pivote sur un axe 20a de la mâchoire mobile 12 qu'elle pousse dans le sens de la fermeture de la mâchoire mobile. Cette dernière comporte à son extrémité une partie semi-cylindrique 23 en appui sur un flanc de la matrice mobile 14, laquelle coulisse dans des rainures suivant un déplacement axial. Les biellettes 20, 22 peuvent être doubles comme représenté sur la figure 2.The double cam 15 acts on the movable roller 21 integral with the two links 20, 22 one of which 22 pivots on a fixed axis 22a and the other 20 pivots on an axis 20a of the movable jaw 12 which it pushes in the direction closing the movable jaw. The latter comprises at its end a semi-cylindrical part 23 bearing on a side of the movable matrix 14, which slides in grooves according to an axial displacement. The links 20, 22 can be double as shown in FIG. 2.

La came double 15 est solidaire d'une ou deux roues dentées (16, 16b) disposées de chaque côté de la came, avec cliquet d'avance 17 et cliquet de retenue 24, celui-ci pivote sur un axe 24a et est sollicité par un ressort 24b. La came double 15 avance pas à pas, toujours dans le même sens, lorsque l'on manoeuvre la poignée mobile 13 qui agit sur le cliquet d'avance 17 fixé sur son bras de levier par l'axe 17a. Le ressort de tension 25 de la mâchoire mobile maintient les matrices en position fermée sur le manchon à sertir.The double cam 15 is integral with one or two toothed wheels (16, 16b) disposed on each side of the cam, with advance pawl 17 and retaining pawl 24, the latter pivots on an axis 24a and is biased by a spring 24b. The double cam 15 advances step by step, always in the same direction, when the movable handle 13 which operates on the advance pawl 17 fixed on its lever arm by the axis 17a. The tension spring 25 of the movable jaw keeps the dies in the closed position on the crimp sleeve.

L'action de la gâchette 19 a pour effet d'amener le galet mobile 21 du système de biellettes dans le creux 32 de la came double 15 en tendant le ressort 25.The action of the trigger 19 has the effect of bringing the movable roller 21 of the rod system into the hollow 32 of the double cam 15 by tensioning the spring 25.

On peut prévoir un accrochage 26 entre la mâchoire mobile 12 et la matrice mobile 14 pour le rappel de cette dernière lors du déplacement de la mâchoire mobile ou bien un ressort de rappel de la matrice mobile.There can be an attachment 26 between the movable jaw 12 and the movable die 14 for the recall of the latter during movement of the movable jaw or else a return spring of the movable die.

La pince est réalisée sous forme de deux flasques 27, 28 en alliage léger ou en matière plastique emprisonnant le mécanisme proprement dit. Pour le montage on peut positionner le mécanisme dans un flasque puis placer le deuxième flasque sur le premier, et ensuite on verrouille les deux flasques au moyen de vis ou d'un accrochage. Le montage s'en trouve facilité.The clamp is produced in the form of two flanges 27, 28 of light alloy or of plastic material trapping the mechanism itself. For mounting, the mechanism can be positioned in a flange, then place the second flange on the first, and then the two flanges are locked with screws or a hook. The assembly is thereby facilitated.

Le guide 10 servant de pièce d'usure est fixé de façon interchangeable sur la matrice mobile. Une bague souple 30 en caoutchouc permet l'arrêt de la came double 15 en position fixe après la fin de chaque demi-course de la came. La pince comporte des poignées isolantes 31 emmanchées sur les poignées fixe 33 et mobile 13 pour le travail sous tension.The guide 10 serving as a wearing part is fixed interchangeably on the movable matrix. A flexible rubber ring 30 stops the double cam 15 in a fixed position after the end of each half-stroke of the cam. The clamp has insulating handles 31 fitted on the fixed 33 and movable 13 handles for working under tension.

La mise en place d'un manchon dans la pince s'effectue en appuyant sur la gâchette 19 de façon à écarter la matrice mobile de la matrice fixe. Une fois le manchon positionné, on lâche la gâchette et le manchon conserve sa position dans la pince, serré entre les matrices sous l'action du ressort 25. Le sertissage s'effectue en agissant sur la poignée mobile 13 avec ressort de rappel 34, qui fait progresser pas à pas la roue dentée 16 et par suite la came 15 qui lui est solidaire. Cette progression pas à pas de la demi- came 15 produit une grande force de fermeture de la matrice mobile vers la matrice fixe et réalise le sertissage du manchon. La seconde demi- came permet de réaliser un deuxième sertissage.The establishment of a sleeve in the clamp is carried out by pressing the trigger 19 so as to separate the movable matrix from the fixed matrix. Once the sleeve is positioned, the trigger is released and the sleeve keeps its position in the clamp, clamped between the dies under the action of the spring 25. The crimping is carried out by acting on the movable handle 13 with return spring 34, which advances the gear 16 step by step and consequently the cam 15 which is integral with it. This step-by-step progression from the half-cam 15 produces a large closing force from the movable die to the fixed die and crimps the sleeve. The second half-cam allows a second crimping to be carried out.

Le maintien du manchon à sertir entre les matrices permet de le positionner avec une meilleure précision avant le sertissage. Il permet également de libérer une main de l'opérateur. La pince peut ainsi être tenue d'une seule main par l'opérateur pendant que le manchon est maintenu entre les mâchoires de la pince sous l'action, du ressort de tension 25.Maintaining the crimp sleeve between the dies makes it possible to position it with better precision before crimping. It also frees one hand from the operator. The clamp can thus be held with one hand by the operator while the sleeve is held between the jaws of the clamp under the action of the tension spring 25.

Toutefois, il peut être nécessaire de dégager le matériau à sertir de l'emprise des matrices, sans réaliser l'opération de sertissage complète telle qu'évoquée plus haut. En ce but il est prévu une gâchette auxiliaire de dégagement 36 montée sur l'axe 17a et faisant légèrement saillie hors de la poignée mobile. Cette gâchette 36 comporte un ergot 36a qui vient s'engager dans un becquet de rappel 17c du cliquet d'avance 17. Le becquet 17c est agencé de manière à soulever le cliquet 17 hors des dents de la roue dentée 16 et à lui faire repousser le cliquet de retenue 24 hors des dents de la même roue dentée 16, lorsque la gâchette 36 est actionnée, ici par pression, et que la poignée mobile 13 est pressée vers la poignée fixe 33.However, it may be necessary to release the material to be crimped from the grip of the dies, without carrying out the complete crimping operation as mentioned above. For this purpose there is provided an auxiliary release trigger 36 mounted on the axis 17a and slightly protruding from the movable handle. This trigger 36 comprises a lug 36a which engages in a return spoiler 17c of the advance pawl 17. The spoiler 17c is arranged so as to lift the pawl 17 out of the teeth of the toothed wheel 16 and to make it repel the retaining pawl 24 outside the teeth of the same toothed wheel 16, when the trigger 36 is actuated, here by pressure, and when the movable handle 13 is pressed towards the fixed handle 33.

La came 15 n'étant plus retenue, il suffit d'appuyer sur la gâchette 19 pour communiquer un couple à cette came 15 via le galet 21 et pour permettre l'écartement de la mâchoire mobile 12.As the cam 15 is no longer retained, it suffices to press the trigger 19 to communicate a torque to this cam 15 via the roller 21 and to allow the movable jaw 12 to move apart.
