Description

La présente invention concerne une borne de raccordement pour conducteur de câble, et en particulier une telle borne destinée à être fixée par soudure, à la façon d'un composant discret classique, sur un circuit impriné.The present invention relates to a connection terminal for cable conductor, and in particular such a terminal intended to be fixed by soldering, in the manner of a conventional discrete component, on a printed circuit.

La présente invention s'applique notamment au raccordement de conducteur de câble coaxial.The present invention applies in particular to the connection of a coaxial cable conductor.

La description qui va suivre se rapporte à cette application sans toutefois que celle-ci puisse être considérée comme limitative.The description which follows relates to this application without however that it can be considered as limiting.

Les bornes de raccordement pour conducteur de câble coaxial destinées à être fixées par soudure sur un circuit imprimé, jusqu'ici proposées sont composées d'une façon générale d'une plaquette fixée sur le circuit imprimé, d'une contre-plaquette séparée disposée en regard de la plaquette précitée et sollicitée en rapprochement de celle-ci par une vis de serrage.The connection terminals for coaxial cable conductor intended to be fixed by soldering on a printed circuit, hitherto proposed are generally composed of a plate fixed on the printed circuit, of a separate counter-plate arranged in look of the aforementioned wafer and biased in approach thereof by a clamping screw.

Bien que ces bornes aient rendu de grands services, celles-ci ne donnent pas pleinement satisfaction, en ce qui concerne en particulier leur facilité d'utilisation, la qualité du contact établi avec le conducteur de câble coaxial, la fiabilité et le coût.Although these terminals have rendered great services, they are not fully satisfactory, in particular with regard to their ease of use, the quality of the contact established with the coaxial cable conductor, the reliability and the cost.

La présente invention vient maintenant améliorer la situation en proposant une borne de raccordement pour conducteur de câble coaxial constituée d'une pince d'un seul tenant en tôle comprenant deux branches en regard reliées par un pontet de liaison qui leur est généralement transversal, des pattes en saillie sur l'une des branches adaptées pour être introduites dans des orifices d'une embase support formant circuit imprimé et,à ce niveau, être raccordées par soudure à des liaisons électriques, l'une des branches possédant un orifice qui reçoit le corps d'une vis de serrage, cette branche servant en outre d'appui à la tête de la vis, et l'autre branche possédant une ouverture, en regard de l'orifice, avec laquelle vient en prise le filetage de la vis pour serrer un conducteur de câble introduit entre les branches.The present invention now improves the situation by proposing a connection terminal for coaxial cable conductor consisting of a clamp in one piece made of sheet metal comprising two facing branches connected by a connecting bridge which is generally transverse to them, legs projecting from one of the branches adapted to be introduced into the orifices of a support base forming a printed circuit and, at this level, being connected by soldering to electrical connections, one of the branches having an orifice which receives the body a clamping screw, this branch also serving as a support for the head of the screw, and the other branch having an opening, facing the orifice, with which the thread of the screw engages to tighten a cable conductor inserted between the branches.

Les bornes de raccordement ci-dessus définies, conformes à la présente invention, présentent une dynamique de serrage plus importante que les bornes de raccordement classiques.The connection terminals defined above, in accordance with the present invention, have a greater clamping dynamic than the conventional connection terminals.

Par ailleurs, les bornes de raccordement conformes à la présente invention présentent une meilleure tenue à l'arrachement.Furthermore, the connection terminals according to the present invention have better resistance to tearing.

Des essais réalisés sur des bornes de raccordement conformes à la présente invention ont également montré que celles-ci présentent une résistance électrique plus faible que les bornes de raccordement classiques, ce qui est bien entendu essentiel pour la qualité du raccordement. Cet avantage semble dû essentiellement au fait que selon l'invention, les deux branches sont réalisées d'un seul tenant, alors que par le passé, la plaquette et la contre-plaquette des bornes de raccordement étaient réalisées séparément et raccordées sur le plan électrique par la vis de serrage.Tests carried out on connection terminals in accordance with the present invention have also shown that they have a lower electrical resistance than conventional connection terminals, which is of course essential for the quality of the connection. This advantage seems essentially due to the fact that according to the invention, the two branches are made in one piece, while in the past, the plate and the counterplate of the connection terminals were produced separately and electrically connected by the clamping screw.

De façon avantageuse, la borne de raccordement conforme à la présente invention peut présenter un serrage à pas rapide.Advantageously, the connection terminal according to the present invention can have a rapid pitch tightening.

Un autre avantage fondamental de la présente invention réside dans la possibilité de livrer la borne de raccordement en position ouverte, sans risquer de perdre la vis de serrage. Là encore, cet avantage résulte de la réalisation de la borne de raccordement conforme à la présente invention d'un seul tenant, de telle sorte que, grâce à l'élasticité résiduelle entre les branches de la pince, l'une en prise avec le filetage de la vis de serrage, l'autre en appui contre la tête de celle-ci, la vis n'est pas sujette à desserrage à la suite de manipulations diverses ou de vibrations.Another fundamental advantage of the present invention lies in the possibility of delivering the connection terminal in the open position, without risking losing the tightening screw. Again, this advantage results from the realization of the connection terminal according to the present invention in one piece, so that, thanks to the residual elasticity between the branches of the clamp, one engaged with the thread of the clamping screw, the other pressing against the head of the latter, the screw is not subject to loosening following various manipulations or vibrations.

Par contre, dans le cas des bornes de raccordement classiques, la plaquette et la contre-plaquette étant formées de pièces séparées, en position ouverte non serrée de la borne, la vis est très sensible aux vibrations et donc sujette à desserrage. De ce fait, il était jusqu'ici indispensable de livrer les bornes de raccordement pour conducteur de câble en position de fermeture serrée afin de bloquer la vis de serrage.On the other hand, in the case of conventional connection terminals, the plate and the counter-plate being formed from separate parts, in the open, non-tight position of the terminal, the screw is very sensitive to vibrations and therefore subject to loosening. As a result, it has hitherto been essential to deliver the connection terminals for cable conductor in the tightly closed position in order to block the clamping screw.

Ainsi, avant toute utilisation, les bornes de raccordement devaient dans un premier temps être placées en position ouverte, en veillant dans cet état à ne pas perdre la vis de serrage.Thus, before any use, the connection terminals must first be placed in the open position, taking care in this state not to lose the tightening screw.

Un câble coaxial comprend généralement une âme centrale électriquement conductrice, revêtue d'une protection électriquement isolante enveloppée d'une tresse cylindrique en matériau électriquement conducteur, servant de masse et/ou de blindage, le tout étant recouvert d'une protection électriquement isolante.A coaxial cable generally comprises an electrically conductive central core, coated with an electrically insulating protection wrapped in a cylindrical braid made of electrically conductive material, serving as ground and / or shielding, the whole being covered with an electrically insulating protection.

La borne de raccordement conforme à la présente invention peut être l'objet de divers modes de réalisation adaptés respectivement pour être raccordés à l'âme conductrice centrale du câble coaxial ou au blindage de masse de celui-ci.The connection terminal according to the present invention can be the subject of various embodiments adapted respectively to be connected to the central conductive core of the coaxial cable or to the ground shielding of the latter.

Selon une caractéristique avantageuse de l'invention, le pontet de liaison est incurvé vers l'intérieur de la pince.According to an advantageous characteristic of the invention, the connecting bridge is curved towards the inside of the clamp.

Cette caractéristique s'applique de préférence aux bornes de raccordement destinées à être reliées au blindage de masse.This characteristic preferably applies to the connection terminals intended to be connected to the ground shield.

Selon un mode de réalisation avantageux de la présente invention concernant tout particulièrement cette dernière application, chaque branche possède la forme générale d'un "L".According to an advantageous embodiment of the present invention relating particularly to this latter application, each branch has the general shape of an "L".

Plus précisément, selon l'invention, l'une des branches possède de préférence une ailette en forme de calotte cylindrique, convexe vers l'extérieur, destinée à être portée au contact du conducteur du câble.More precisely, according to the invention, one of the branches preferably has a fin in the form of a cylindrical cap, convex towards the outside, intended to be brought into contact with the cable conductor.

L'ailette précitée en forme de calotte cylindrique est avantageusement évasée vers l'extérieur au niveau de la zone d'engagement du conducteur, afin de faciliter l'introduction de ce dernier dans la borne.The aforementioned fin in the form of a cylindrical cap is advantageously flared outwards at the level of the driver's engagement zone, in order to facilitate the introduction of the latter into the terminal.

Ainsi, selon un mode de réalisation de bornes de raccordement conformes à la présente invention, considéré actuellement comme préférentiel, et applicable notamment au raccordement des blindages demasse du câble coaxial, l'une au moins des branches est formée d'une ailette principale raccordée au pontet de liaison et d'une ailette secondaire raccordée à l'ailette principale et généralement transversale à celle-ci, l'ailette principale étant munie de l'orifice ou l'ouverture recevant la vis, l'ailette secondaire ayant la forme d'une calotte cylindrique convexe vers l'extérieur, destinée à être portée au contact du conducteur, et un bord libre au moins de l'ailette principale étant déforme par pliage pour former raidisseur.Thus, according to one embodiment of connection terminals in accordance with the present invention, currently considered preferential, and applicable in particular at the connection of the mass shields of the coaxial cable, at least one of the branches is formed by a main fin connected to the connecting bridge and a secondary fin connected to the main fin and generally transverse thereto, l main fin being provided with the orifice or opening receiving the screw, the secondary fin having the shape of a cylindrical cap convex towards the outside, intended to be brought into contact with the conductor, and at least one free edge of the main fin being deformed by folding to form a stiffener.

Selon une autre caractéristique avantageuse de la présente invention, applicable notamment aux bornes de raccordement destinées à être reliées à l'âme centrale du câble coaxial, la largeur du pontet de liaison, considérée dans une direction généralement parallèle aux branches, est inférieure à la largeur de ces dernières.According to another advantageous characteristic of the present invention, applicable in particular to connection terminals intended to be connected to the central core of the coaxial cable, the width of the connecting bridge, considered in a direction generally parallel to the branches, is less than the width of these.

Cette caractéristique permet en particulier de faire dépasser l'âme conductrice centrale du câble coaxial sur l'extérieur de la borne de raccordement, à côté du pontet de liaison, et ainsi de vérifier aisément le positionnement correct de l'âme conductrice centrale sur la borne de raccordement.This characteristic makes it possible in particular to make the central conductive core of the coaxial cable protrude on the outside of the connection terminal, next to the connecting bridge, and thus to easily verify the correct positioning of the central conductive core on the terminal. connection.

Selon une autre caractéristique avantageuse de la présente invention applicable en particulier aux bornes de raccordement destinées à être reliées à l'âme centrale du câble coaxial, les deux branches de la pince sont généralement planes et parallèles.According to another advantageous characteristic of the present invention applicable in particular to connection terminals intended to be connected to the central core of the coaxial cable, the two branches of the clamp are generally planar and parallel.

L'ouverture apte à coopérer avec le filetage de la vis, réalisée dans l'une des branches de la pince est avantageusement formée par découpe et déformation de languettes dans la branche précitée.The opening capable of cooperating with the thread of the screw, produced in one of the branches of the clamp is advantageously formed by cutting and deformation of tongues in the aforementioned branch.

On va dans un premier temps décrire la structure des bornes de raccordement pour blindage de masse de câble coaxial illustrées sur les figures 1 à 1 G.We will first describe the structure of the connection terminals for ground shielding of coaxial cable illustrated in Figures 1 to 1 G.

Ces bornes de raccordement 10 comprennent deux branches 20, 40 généralement parallèles, reliées par un pontet de liaison 60 qui leur est généralement transversal.These connection terminals 10 comprise two branches 20, 40 generally parallel, connected by a connecting bridge 60 which is generally transverse to them.

Selon l'exemple de réalisation représenté sur les figures annexées, chaque branche de la borne de liaison 10 possède la forme générale d'un "L".According to the embodiment shown in the appended figures, each branch of the connection terminal 10 has the general shape of an "L".

Plus précisément, chaque branche est formée d'une ailette principale 21, 41 raccordée au pontet de liaison 60, et d'une ailette secondaire 22, 42 raccordée à l'ailette principale 21, 41, à distance du pontet de liaison 60, en étant généralement transversale à celle-ci, à la façon d'un "L".More specifically, each branch is formed of a main fin 21, 41 connected to the connecting bridge 60, and a secondary fin 22, 42 connected to the main fin 21, 41, at a distance from the connecting bridge 60, in being generally transverse thereto, like an "L".

Dans la suite de la description, les branches 20 et 40 seront dénommées respectivement branche supérieure et branche inférieure, sans que cette désignation puisse être considérée comme limitative en ce qui concerne le positionnement de la borne à l'utilisation.In the following description, the branches 20 and 40 will be called respectively upper branch and lower branch, without this designation can be considered as limiting with regard to the positioning of the terminal in use.

L'aile principale 21 de la branche supérieure 20 est munie au voisinage de son extrémité opposée au pontet de liaison 60 d'un orifice 23 généralement circulaire destiné à recevoir en traversée le corps d'une vis de serrage 90.The main wing 21 of the upper branch 20 is provided in the vicinity of its end opposite to the connecting bridge 60 with a generally circular orifice 23 intended to receive the body of a clamping screw 90 through it.

De préférence, le centre des orifices 23 coïncide avec l'intersection des axes longitudinaux médians de l'ailette principale 21 et de l'aile secondaire 22, telsqu'illustrésrespectivement 24 et 25 sur la figure 4.Preferably, the center of the orifices 23 coincides with the intersection of the median longitudinal axes of the main fin 21 and the secondary wing 22, as illustrated respectively 24 and 25 in FIG. 4.

Le diamètre de l'orifice 23 est inférieur au diamètre de la tête 91 de la vis de serrage 90, de telle sorte que la surface externe de la branche supérieure 20, opposée à la branche 40 serve d'appui à la tête 91 de la vis.The diameter of the orifice 23 is less than the diameter of the head 91 of the clamping screw 90, so that the external surface of the upper branch 20, opposite to the branch 40 serves to support the head 91 of the screw.

L'ailette principale 41 de la branche inférieure 40 possède une ouverture 43 ménagée en regard de l'orifice 23 précité et adaptée pour venir en prise avec le filetage de la vis 90 pour permettre le rapprochement des deux branches 20, 40 lorsque la vis 90 est entraînée en rotation dans l'ouverture 43, pour serrer un conducteur de câble introduit entre les branches 20, 40.The main fin 41 of the lower branch 40 has an opening 43 formed opposite the aforementioned orifice 23 and adapted to engage with the thread of the screw 90 to allow the two branches 20, 40 to be brought together when the screw 90 is rotated in the opening 43, to clamp a cable conductor introduced between the branches 20, 40.

Là encore, le cent de l'ouverture 43 coincide de préférence avec l'intersection des axes longitudinaux médians de l'ailette principale 41 et de l'ailette secondaire 42 homologuesdes axes'24 et 25 schématiquement représentés sur la figure 4.Again, the cent of the opening 43 preferably coincides with the intersection of the median longitudinal axes of the main fin 41 and the secondary fin 42 homologous to the axes 24 and 25 schematically represented in FIG. 4.

Les ouvertures 43 précitées peuvent faire l'objet de diverses variantes de réalisation connues en soi pour l'assemblage de vis sur des tôles.The aforementioned openings 43 can be the subject of various variant embodiments known per se for the assembly of screws on sheets.

Selon un mode de réalisation considéré actuellement comme préférentiel, tel que représenté sur la figure 2, l'ouverture 43 adaptée pour coopérer avec le filetage de la vis 90 est formée par découpe et déformation de languettes 44, 45 vers l'extérieur de la pince 10.According to an embodiment currently considered as preferred, as shown in FIG. 2, the opening 43 adapted to cooperate with the thread of the screw 90 is formed by cutting and deformation of the tongues 44, 45 towards the outside of the clamp 10.

La branche inférieure est de plus munie d'une pluralité de pattes 46, 47, 48 en saillie vers l'extérieur de la pince sensiblement perpendiculairement à la branche inférieure 40, cette dernière mis à part les pattes 46, 47, 48 et les languettes 44, 45 étant généralement plane .The lower branch is further provided with a plurality of legs 46, 47, 48 projecting outwards from the clamp substantially perpendicular to the lower branch 40, the latter apart from the legs 46, 47, 48 and the tongues 44, 45 being generally planar.

Plus précisément, on aperçoit sur les figures, deux pattes 47, 48 formées par pliage sur le bord libre avant 49 de la branche inférieure 40, opposé au pontet de liaison 60 et généralement parallèle à celui -ci.More specifically, we can see in the figures, two tabs 47, 48 formed by folding on the free front edge 49 of the lower branch 40, opposite the connecting bridge 60 and generally parallel thereto.

On aperçoit également sur les figures, une troisième patte 46 formée par pliage sur le bord libre 50 de l'ailette secondaire 42 dirigé vers le pontet de liaison 60 et sensiblement parallèle à celui-ci.We also see in the figures, a third tab 46 formed by folding on the free edge 50 of the secondary fin 42 directed towards the connecting bridge 60 and substantially parallel thereto.

Le nombre de pattes 46, 47, 48 précitées ne doit cependant pas être considéré comme limitatif.The number of legs 46, 47, 48 mentioned above should not however be considered as limiting.

L'ailette secondaire 22 de la branche supérieure 20 a la forme générale d'une calotte hémicylindrique de révolution autour d'un axe (schématiquement illustré 26 sur la figure 4) parallèle à l'axe 24 précité et donc sensiblement orthogonal au pontet de liaison 60.The secondary fin 22 of the upper branch 20 has the general shape of a semi-cylindrical cap of revolution around an axis (schematically illustrated 26 in FIG. 4) parallel to the above-mentioned axis 24 and therefore substantially orthogonal to the connecting bridge 60.

La forme de cette ailette secondaire 22, et par conséquent son rayon de courbure sont bien entendu adaptés pour permettre un contact étroit contre le blindage de masse généralement cylindrique du câble coaxial, pincé à l'utilisation entre les ailettes secondaires 22 et 42.The shape of this secondary fin 22, and consequently its radius of curvature are of course adapted to allow close contact against the generally cylindrical mass shield of the coaxial cable, pinched in use between the secondary fins 22 and 42.

De préférence, comme cela est illustré sur les figures, sous la référence 27, pour faciliter l'introduction du conducteur entre les branches 20 et 40 de la pince, l'ailette 22 en forme de calotte cylindrique est évasée vers l'extérieur au niveau de la zone d'engagement du conducteur, soit au niveau du bord libre 28 de l'ailette secondaire 22 qui est opposé au pontet de liaison 60 et sensiblement parallèle à celui-ci.Preferably, as illustrated in the figures, under reference 27, to facilitate the introduction of the conductor between the arms 20 and 40 of the clamp, the fin 22 in the form of a cylindrical cap is flared outwards at the level of the driver's engagement zone, ie at the free edge 28 of the secondary fin 22 which is opposite to the connecting bridge 60 and substantially parallel thereto.

On remarquera à l'examen des figures que la vis de serrage 90 engagée dans les ailettes principales 21, 41 est placée à côté de la zone de serrage du conducteur de câble coaxial définie par les ailettes secondaires 22, 42.It will be noted on examining the figures that the clamping screw 90 engaged in the main fins 21, 41 is placed next to the clamping area of the coaxial cable conductor defined by the secondary fins 22, 42.

Pour cette raison, afin d'éviter une déformation de l'ailette principale 21 lors du serrage de la vis 90 tendant à rapprocher les branches 20, 40 à l'encontre de la résistance élastique du pontet de liaison 60 et du conducteur de câble coaxial introduit entre les ailettes secondaires 22, 42, des plis 29, 30 formant raidisseur sont réalisés sur les bords libres 31, 32 respectivement orthogonaux de l'ailette principale 21, et respectivement parallèles aux axes 24 et 25 précités.For this reason, in order to avoid deformation of the main fin 21 when tightening the screw 90 tending to bring the branches 20, 40 against the elastic resistance of the connecting bridge 60 and the coaxial cable conductor introduced between the secondary fins 22, 42, folds 29, 30 forming a stiffener are formed on the free edges 31, 32 respectively orthogonal to the main fin 21, and respectively parallel to the axes 24 and 25 above.

Plus précisément, comme cela apparaît à l'examen des figures 2, 3 et 4, les raidisseurs 29, 30 sont formés par pliage des bords 31, 32 vers l'intérieur de la pince, soit vers la branche inférieure 40.More precisely, as appears on examining FIGS. 2, 3 and 4, the stiffeners 29, 30 are formed by folding the edges 31, 32 towards the inside of the clamp, ie towards the lower branch 40.

Par ailleurs, selon une autre caractéristique importante de l'invention, comme cela apparaît notamment à l'examen de la figure 2, le pontet de liaison 60 est incurvé vers l'intérieur de la pince.Furthermore, according to another important characteristic of the invention, as appears in particular on examining FIG. 2, the connecting bridge 60 is curved towards the inside of the clamp.

Cette caractéristique permet de limiter l'encombrement extérieur de la borne 10, et ainsi de rapprocher la borne 10 précitée et une borne 100, telle qu'illustrée sur les figures 11 et 12 destinée à être reliée à l'âme centrale conductrice du câble coaxial, tout en respectant les spécifications électriques généralement imposées.This characteristic makes it possible to limit the external dimensions of the terminal 10, and thus to bring the above-mentioned terminal 10 closer to a terminal 100, as illustrated in FIGS. 11 and 12 intended to be connected to the central conductive core of the coaxial cable. , while respecting the generally imposed electrical specifications.

Selon l'illustration donnée sur les figures annexées, la largeur du pontet de liaison 60, considérée sensiblement parallèlement aux branches 20 et 40 est égale à la largeur des ailettes principales 21, 41 considérée transversalement à l'axe 24 précité.According to the illustration given in the appended figures, the width of the connecting bridge 60, considered substantially parallel to the branches 20 and 40 is equal to the width of the main fins 21, 41 considered transversely to the aforementioned axis 24.

De préférence, comme cela est illustré sur la figure 4, les bornes de raccordement 10 sont livrées sous forme de bandes d'une pluralité de bornes raccordées entre elles par des languettes 70 reliant entre elles les branches inférieures40 des différentes bornes 10. Cette caractéristique est particulièrement avantageuse lorsque les blindages de différents câbles coaxiaux reliés à une même embase de circuit imprimé possèdent une masse commune.Preferably, as illustrated in FIG. 4, the connection terminals 10 are supplied in the form of strips of a plurality of terminals connected together by tabs 70 connecting the lower branches 40 of the various terminals 10 to one another. This characteristic is particularly advantageous when the shields of different coaxial cables connected to the same printed circuit base have a common ground.

Ces languettes de liaison 70 présentent de préférence une faible largeur de telle sorte que les languettes puissent être aisément découpées dans le cas où une seule borne 10 doit être utilisée ou encore lorsque les différentes bornes 10 fixées sur une embase commune 1 de circuit imprimé ne doivent pas être reliées entre elles.These connecting tabs 70 preferably have a small width so that the tabs can be easily cut in the case where a single terminal 10 must be used or when the different terminals 10 fixed on a common base 1 of printed circuit must not be related to each other.

On va maintenant décrire la structure de la borne de raccordement 100 illustrée sur les figures 11 à 14 destinée à être reliée à l'âme conductrice centrale d'un câble coaxial.We will now describe the structure of the connection terminal 100 illustrated in Figures 11 to 1 4 intended to be connected to the central conductive core of a coaxial cable.

Là encore, la borne 100 comprend deux branches 120, 140 en regard reliées par un pontet de liaison 160 qui leur est généralement transversal. L again, the terminal 100 comprises two arms 120, 140 facing connected by a bridge connection 160 that is generally transverse to them.

Dans la suite de la description, les branches 120 et 140 seront dénommées respectivement branche supérieure et branche inférieure sans que cette désignation puisse être considérée comme limitative en ce qui concerne le positionnement de la borne à l'utilisation.In the following description, the branches 120 and 140 will be called respectively upper branch and lower branch without this designation can be considered as limiting with regard to the positioning of the terminal in use.

Chaque branche 120, 140 est généralement plane et présente un contour sensiblement rectangulaire.Each branch 120, 140 is generally planar and has a substantially rectangular outline.

La branche supérieure 120 est munie d'un orifice 123 recevant en traversée le corps d'une vis de serrage 190. Le diamètre de l'orifice 123 est inférieure au diamètre de la tête évasée de la vis de serrage 190. Ainsi, la surface externe 121 de la branche supérieure 120, opposée à la branche inférieure 140 sert d'appui à la tête de la vis 190.The upper branch 120 is provided with an orifice 123 receiving the body of a clamping screw 190 therein. The diameter of the orifice 123 is less than the diameter of the flared head of the clamping screw 190. Thus, the surface external 121 of the upper branch 120, opposite the lower branch 140 serves to support the head of the screw 190.

L'orifice 123 est de préférence réalisé en position centrale sur l'aile supérieure 120..The orifice 123 is preferably made in a central position on the upper wing 120.

L'aile inférieure 140 possède une ouverture 142 en regard de l'orifice 123, adaptée pour venir en prise avec le filetage de la vis de serrage 190, pour solliciter,lors de la rotation de la vis 190 dans l'ouverture 143, le rapprochement des branches 120 et 140 afin de serrer le conducteur central du câble coaxial entre les branches 120 et 140.The lower wing 140 has an opening 142 opposite the orifice 123, adapted to engage with the thread of the clamping screw 190, to urge, during the rotation of the screw 190 in the opening 143, the bringing branches 120 and 140 together to clamp the central conductor of the coaxial cable between branches 120 and 140.

Là encore, l'ouverture 143 peut faire l'objet de diverses variantes de réalisation.Again, the opening 143 can be the subject of various alternative embodiments.

Selon un mode de réalisation considéré actuellement comme préférentiel, l'ouverture 143 est réalisée par découpe de languettes 144, 145 dans la branche inférieure 140 et déformation de celles-ci vers l'extérieur de la pince, comme illustré sur la figure 11.:According to an embodiment currently considered preferential, the opening 143 is produced by cutting tongues 144, 145 in the lower branch 140 and deformation of these towards the outside. of the pliers, as illustrated in figure 11 .:

Le pontet de liaison 160 reliant de façon élastique les branches 120 et 140 présente une enveloppe convexe vers l'extérieur de la pince, et généralement hémicylindrique de révolution autour-d'un axe parallèle aux embases 120 et 140 précitées.The connecting bridge 160 connecting the branches 120 and 140 in an elastic manner has a convex envelope towards the outside of the clamp, and generally semi-cylindrical in revolution around an axis parallel to the abovementioned bases 120 and 140.

La branche supérieure 120 est munie de pattes en saillie 146, 147, 148, adaptées, de façon similaire aux pattes 46, 47 et 48 précitées,pour être introduites dans des orifices ménagés dans l'embase support 1 de circuit imprimé et, à ce niveau, être raccordée par soudure à des liaisons électriques.The upper branch 120 is provided with projecting tabs 146, 147, 148, adapted, similarly to the tabs 46, 47 and 48 mentioned above, to be introduced into orifices formed in the support base 1 of the printed circuit and, to this level, be connected by welding to electrical connections.

De préférence, comme cela est illustré sur les figures, la branche supérieure 120 est munie sur chacun de ses quatre coins d'une patte (146, 147, 148) repliée perpendiculairement au plan de la branche supérieure 120 vers la branche inférieure 140, en dépassant largement au-delà de cette dernière, pour être engagée dans les orifices précités ménagés dans l'embase de circuit imprimé 1.Preferably, as illustrated in the figures, the upper branch 120 is provided on each of its four corners with a tab (146, 147, 148) folded perpendicular to the plane of the upper branch 120 towards the lower branch 140, in protruding well beyond the latter, to be engaged in the aforementioned orifices provided in the printed circuit base 1.

Comme représenté sur la figure 12, et comme cela est plus précisément illustré pour la patte 147, chacune des pattes formée en saillie sur la branche supérieure 120 possède de préférence une première partie 149 adjacente à la branche supérieure 120 qui se prolonge par une seconde partie 150 de plus faible largeur.As shown in FIG. 12, and as is more precisely illustrated for the tab 147, each of the tabs projecting from the upper branch 120 preferably has a first part 149 adjacent to the upper branch 120 which is extended by a second part 150 of smaller width.

Ainsi, le décrochement prévu entre les deux parties 149, 150 délimite une surface d'appui 151 généralement parallèle aux branches 120, 140 et dirigée vers l'extrémité libre des pattes 146, 147 et 148 pour servir de butée à la borne de raccordement 100 lors du positionnement de celles-ci sur l'embase de circuit imprimé 1.Thus, the recess provided between the two parts 149, 150 delimits a bearing surface 151 generally parallel to the branches 120, 140 and directed towards the free end of the legs 146, 147 and 148 to serve as a stop for the connection terminal 100 when positioning these on the printed circuit base 1.

Selon une autre caractéristique importante de la présente invention, la largeur 1. du pontet 160, considérée parallèlement aux branches 120, 140 est infé- rieure aux largeurs 12 correspondantes des branches 120, 140.According to another important characteristic of the present invention, the width 1. of the trigger guard 160, considered parallel to the branches 120, 140 is less than the corresponding widths 12 of the branches 120, 140.

Ainsi, comme cela est illustré sur la figure 12, l'âme centrale introduite dans la borne 100 par l'ouverture de celle-ci opposée au pontet de liaison 160, peut émerger à l'extérieur de la borne 100, à côté du pontet 160, ce qui permet à l'installateur de contrôler aisément le positionnement correct de l'âme électriquement conductrice A.Thus, as illustrated in FIG. 12, the central core introduced into terminal 100 by the opening of the latter opposite the connecting bridge 160, can emerge outside the terminal 100, next to the bridge 160, which allows the installer to easily control the correct positioning of the electrically conductive core A.

De préférence, selon la présente invention, les bornes de raccordement 10 et 100 sont réalisées en acier-ressort traité puis revêtu d'un dépôt métallique le rendant apte à être brasé à l'étain, pour permettre un assemblage des bornes sur une embase de circuit imprimé 1, par soudure, par exemple par soudure à la vague à la façon d'un composant discret classique.Preferably, according to the present invention, the connection terminals 10 and 100 are made of treated spring steel then coated with a metallic deposit making it suitable for being soldered with tin, to allow assembly of the terminals on a base of printed circuit 1, by soldering, for example by wave soldering in the manner of a conventional discrete component.

Bien entendu, la présente invention n'est aucunement limitée aux modes de réalisation qui viennent d'être décrits mais s'étend à toute variante conforme à son esprit.Of course, the present invention is in no way limited to the embodiments which have just been described but extends to any variant in accordance with its spirit.

A titre d'exemple, comme cela est représenté sur les figures annexées, on peut envisager de réaliser des crochets anti-retours sur les bornes, en particulier sur la borne 10. Ces crochets anti-retours peuvent être adaptés pour s'enfoncer dans la partie isolant-diélectrique du câble et rendre plus difficile son arrachement par traction.By way of example, as shown in the appended figures, it is possible to envisage making non-return hooks on the terminals, in particular on terminal 10. These non-return hooks can be adapted to sink into the insulating-dielectric part of the cable and making it more difficult to pull it out by traction.

Sur les figures annexées, on a ainsi représenté trois crochets 51 de forme générale triangulaire formés par découpe de languettes dans l'ailette 42 et déformation de ces languettes vers l'intérieur de la borne, la pointe des crochets étant dirigée vers le bord libre 50 pour réaliser un effet anti-retour.In the accompanying figures, there are thus shown three hooks 51 of generally triangular shape formed by cutting tabs in the fin 42 and deformation of these tabs towards the inside of the terminal, the point of the hooks being directed towards the free edge 50 to achieve a non-return effect.

De même, on a représenté trois crochets 33 sur l'ailette secondaire 22. Ces crochets 33 sont allongés transversalement à l'axe de courbure de l'ailette. Les crochets 33 sont réalisés par découpe de languettes dans l'ailette 22 et déformation vers l'intérieur de la borne, le bord libre des crochets 33 étant dirigé vers le pontet de liaison 60.Similarly, three hooks 33 are shown on the secondary fin 22. These hooks 33 are elongated transversely to the axis of curvature of the fin. The hooks 33 are produced by cutting tongues in the fin 22 and deformation towards the inside of the terminal, the free edge of the hooks 33 being directed towards the connecting bridge 60.

Par ailleurs, de préférence, les bords d'engagement des branches 120, 140 de la borne 100 sont évasés vers l'extérieur, comme illustré en 170, 180.Furthermore, preferably, the engagement edges of the branches 120, 140 of the terminal 100 are flared outwards, as illustrated in 170, 180.
