Abstract
Description
La présente invention conceme un bloc de jonction électrique comportant dans un boîtier des bomes de connexion exteme reliées entre elles par une liaison conductrice et une zone de fixation à un support, le boîtier présentant dans le sens de sa largeur une face frontale et des faces latérales dotées d'une part d'une plage porte-repères et d'autre part, entre cette plage et la zone de fixation, d'une zone d'engagement de conducteurs extemes munie d'une ouverture pour l'introduction de ceux-ci dans les bomes. The present invention relates to an electrical terminal block comprising in a housing external connection terminals connected together by a conductive link and a zone of attachment to a support, the housing having in the direction of its width a front face and side faces. provided on the one hand with a marker carrier area and on the other hand, between this area and the fixing area, with an engagement area for external conductors provided with an opening for the introduction thereof in the bomes.
Dans les blocs de jonction connus, la plage porte-repères est disposée obliquement par rapport à une direction orthogonale au plan de montage du bloc sur son support, pour faciliter la visualisation et la manipulation des repères, et la zone d'engagement des conducteurs est sensiblement perpendiculaire au plan de montage. II en résulte que le monteur ne peut pas guider commodément l'extrémité du câble selon une direction sensiblement parallèle à la direction précitée. In known terminal blocks, the marker carrier area is arranged obliquely to a direction orthogonal to the mounting plane of the block on its support, to facilitate viewing and manipulation of the markers, and the conductor engagement area is substantially perpendicular to the assembly plane. As a result, the fitter cannot conveniently guide the end of the cable in a direction substantially parallel to the aforementioned direction.
L'invention a pour but de rendre plus commode l'opération de câblage dans un bloc de jonction du type décrit. The object of the invention is to make the wiring operation more convenient in a terminal block of the type described.
Selon l'invention, la zone d'engagement des conducteurs présente, par rapport à la direction orthogonale au plan de montage sur le support, une obliquité dégageant une région apparente de l'ouverture d'introduction située au débouché de celle-ci et permettant une visualisation et un guidage des conducteurs selon la direction précitée. According to the invention, the zone of engagement of the conductors has, with respect to the direction orthogonal to the mounting plane on the support, an obliquity freeing an apparent region from the introduction opening situated at the outlet thereof and allowing display and guidance of the conductors in the aforementioned direction.
Le câbleur peut ainsi orienter l'extrémité du conducteur selon la direction orthogonale au plan du support puis, après contact de l'extrémité du conducteur avec la région apparente de l'ouverture d'introduction, poursuivre l'introduction en orientant le conducteur parallèlement au plan du support. II est de plus avantageux que l'ouverture d'introduction se présente sous forme d'entonnoir sensiblement tronconique débouchant à l'extérieur du boîtier sur un contour à coins arrondis. The cable operator can thus orient the end of the conductor in the direction orthogonal to the plane of the support and then, after contact of the end of the conductor with the visible region of the insertion opening, continue the introduction by orienting the conductor parallel to the support plan. It is more advantageous that the introduction opening is in the form of a substantially frustoconical funnel opening out of the housing on a contour with rounded corners.
La description va être faite, en regard des dessins annexés, d'un mode de réalisation non limitatif de l'invention. The description will be made, with reference to the accompanying drawings, of a non-limiting embodiment of the invention.
- la figure 1 représente en élévation un bloc de jonction conforme à l'invention. - Figure 1 shows in elevation a terminal block according to the invention.
- la figure 2 est une vue de côté du bloc. - Figure 2 is a side view of the block.
- la figure 3 représente le bloc de jonction en perspective. - Figure 3 shows the terminal block in perspective.
Le bloc de jonction illustré sur les figures 1 à 3 comprend un boîtier 10 en matière isolante et, dans celui-ci, deux bornes 11 de tout type connu, destinées à assurer le serrage et la connexion de conducteurs extemes C. Le boîtier est symétrique par rapport à un plan P et comprend une grande paroi 12 perpendiculaire à ce plan et formant une cloison isolante ; de l'autre côté, le boîtier est ouvert en pouvant être obturé par la cloison 12 d'un autre bloc juxtaposé, mais il pourrait bien entendu présenter une autre grande paroi isolante telle que 12. Le boîtier est aussi délimité par une petite face frontale 13 et deux petites faces latérales 14.Chaque face latérale 14 comprend de façon usuelle une plage 15 porte-repères oblique, proche de la face frontale 13, et une zone d'engagement 16 des conducteurs extemes C ; la zone 16 est munie d'une ouverture 17 pour l'introduction et le retrait des conducteurs C. Le boîtier présente à la partie arrière une zone 18 de fixation, par exemple par des moyens d'encliquetage, sur un support tel qu'un rail normalisé N, définissant un plan de montage Q perpendiculaire à P. The terminal block illustrated in Figures 1 to 3 comprises a housing 10 of insulating material and, in this, two terminals 11 of any known type, intended to ensure the tightening and connection of external conductors C. The housing is symmetrical relative to a plane P and comprises a large wall 12 perpendicular to this plane and forming an insulating partition; on the other side, the housing is open, being able to be closed by the partition 12 of another juxtaposed block, but it could of course have another large insulating wall such as 12. The housing is also delimited by a small front face 13 and two small side faces 14.Each side face 14 usually comprises an area 15 oblique marker carrier, close to the front face 13, and an engagement zone 16 of the outer conductors C; zone 16 is provided with an opening 17 for the insertion and removal of conductors C. The housing has a zone 18 for fixing on the rear part, for example by latching means, on a support such as a standard rail N, defining a mounting plane Q perpendicular to P.
La plage porte-repères 15 fait avec la direction X dans laquelle le câbleur ou l'utilisateur se trouve par rapport au bloc de jonction, un angle aigu Al, tandis que la zone d'engagement 16 fait avec la direction X un angle aigu A2 inférieur à Al. The marker carrier area 15 made with the direction X in which the cable operator or the user is in relation to the terminal block, an acute angle A1, while the engagement zone 16 makes with the direction X an acute angle A2 less than Al.
L'angle A2 est défini par le segment de droite joignant les extrémités avant et arrière des petits côtés 17a, 17b du contour 17c de l'ouverture 17. De la sorte, l'opérateur situé devant le bloc de jonction dans la direction X orthogonale au plan de montage Q peut, d'une part visualiser cette ouverture, d'autre part engager au jugé le conducteur
C parallèlement à P en étant certain que l'extrémité du conducteur va buter, puis glisser, sur une zone apparente 17d située au débouché de l'ouverture et placée, par rapport au plan P1 parallèle à P qui passe par le petit côté intérieur 17a du contour 17c, du côté opposé à P.Le câbleur peut alors incliner le conducteur pour l'orienter selon la direction Y perpendiculaire au plan de symétrie P, afin de l'introduire dans la bome 11 entre la pièce déplaçable Il a de la bome et une barrette de contact 19 (figure 1).The angle A2 is defined by the line segment joining the front and rear ends of the short sides 17a, 17b of the contour 17c of the opening 17. In this way, the operator located in front of the terminal block in the orthogonal X direction on the assembly plan Q can, on the one hand visualize this opening, on the other hand commit the driver to the judge
C parallel to P, being certain that the end of the conductor will abut, then slide, over an apparent area 17d situated at the outlet of the opening and placed, with respect to the plane P1 parallel to P which passes through the small interior side 17a of the contour 17c, on the side opposite to P. The cabler can then tilt the conductor to orient it in the direction Y perpendicular to the plane of symmetry P, in order to introduce it into the boom 11 between the movable part It has the boom and a contact strip 19 (Figure 1).
La zone oblique d'engagement 16 présente transversalement un profil concave (figures 1 et 3) qui accentue l'accessibilité de la région apparente 17d. The oblique engagement zone 16 has transversely a concave profile (FIGS. 1 and 3) which accentuates the accessibility of the visible region 17d.
L'ouverture d'introduction 17 se présente sous forme d'entonnoir sensiblement tronconique débouchant à l'extérieur du boîtier sur le contour 17c, lequel comporte à cet effet des coins arrondis 17e, en contraste avec la section sensiblement rectangulaire du débouché inteme 17e de l'ouverture. Les coins arrondis 17e ont un rayon de courbure supérieur ou comparable à celui des extrémités dénudées des conducteurs usuels C pour assurer un meilleur guidage et un centrage amélioré de ceux-ci en cours d'introduction.The introduction opening 17 is in the form of a substantially frustoconical funnel opening out of the housing on the contour 17c, which for this purpose has rounded corners 17th, in contrast to the substantially rectangular section of the internal outlet 17th of the opening. The rounded corners 17e have a radius of curvature greater than or comparable to that of the stripped ends of the usual conductors C in order to ensure better guidance and improved centering of the latter during introduction.
II convient en outre d'observer que la face frontale 13 du bloc comporte des ouvertures d'accès 20 pour un outil de manoeuvre des bornes 11 et, sur ses bords, entre les ouvertures 20 et la plage porte-repères 15, des oreilles 21 de fixation pour des additifs, ou blocs de jonction de même type, un léger retrait 22 étant ménagé dans la face 14 entre l'oreille 21 et la plage 15. It should also be observed that the front face 13 of the block has access openings 20 for a tool for operating terminals 11 and, on its edges, between the openings 20 and the marker carrier 15, ears 21 of attachment for additives, or terminal blocks of the same type, a slight recess 22 being provided in the face 14 between the lug 21 and the track 15.
