Description

Prise de couraut. Los constructeurs de materiel electrique pour installations interieures cherchent de- puis de tres nombreuses annees ä reduire 1e prix de ce materiel. Ils ont Porte leurs efforts entre autres Sur une construction rationnelle des prises de courant pour appareils electro- domestiques. 0n sait, en effet, que selon los reglements en vigueur, ces prises de courant doivent comporter des Organes de eontact de forme et. de disposition differentes, selon 1e type d'appareil electrodomestique devant etre Branche, ceei independaminent de 1'amperage nominal de 1'appareil. 11 s'ensuit que 1e cons- trueteur est dann 1'obligation de prevoir des prises de courant de forme et de montage dif- ferents correspondant ä chaque type de prises de eourant prescrit, ce qui, evidemment, aug- mente 1e prix de revient de celles-ei. Current socket. Manufacturers of electrical equipment for indoor installations have been seeking for many years to reduce the price of this equipment. They focused their efforts, among other things, on the rational construction of power outlets for domestic appliances. 0n knows, in fact, that according to the regulations in force, these outlets must include Organs of eontact form and. with different layouts, depending on the type of household electrical appliance to be connected, regardless of the nominal amperage of the appliance. It follows that the manufacturer is obliged to provide power sockets of different shape and mounting corresponding to each type of power socket prescribed, which obviously increases the cost price. of these.

Cet etat de Fait est encore rendu plus de- favorable par los trois types de prises de cou- rant preserits pour los trois genres de locaux: eaves, loeaux humides et locaux secs, et par les divers genres de montage possible des prises de eourant (mural, encastre, pour ta- bleaux, avec connexion avant ou arriere, etc.). On voit que 1e nombre des variantes exigees est tres Brand, de Sorte qu'il n'est pas aise de realiser une eonstruction permettant, a 1'aide d'un Beul et intime soele uruni de pieces de contaet et de connexion Standard, de realiser toutes les vaxiantes pouvant etre demandees. This state of affairs is made even more favorable by the three types of power outlets preserted for the three types of premises: dry, wet and dry rooms, and by the various types of possible mounting of the power outlets ( wall-mounted, recessed, for panels, with front or rear connection, etc.). We see that the number of variants required is very high, so that it is not easy to achieve a construction allowing, with the help of a Beul and intimate soele uruni of Standard contact and connection parts, to carry out all the vaxiantes which can be requested.

Neanmoins, divers constructeurs ont dejä mis Sur 1e marche des prises de coiirant re- pondant ä toutes ces exigences. Toutefois, ces prises de courant sont dun prix relativement MW, du fait qu'elles comportent des pizees de contact et de connexion maintenues Sur un socle en ceramique a 1'aide de vis, par scelle- ment ou autre moy en de fixation. Or, non seulement la mise en place et 1e serrage de ces Organes de fixation sont des operations one- reuses, mais 1e prix des vis et des pereages taraudes West pas negligeable, de Sorte quo 1e prix de revient de ces prises de courant est eneore trop eleve. Nevertheless, various manufacturers have already marketed power sockets which meet all these requirements. However, these socket outlets are of a relatively MW price, owing to the fact that they comprise contact and connection sockets held on a ceramic base by means of screws, by sealing or other fixing means. However, not only is the positioning and tightening of these fixing devices costly, but the price of the screws and tapped holes is not negligible, so that the cost price of these socket outlets is still higher. too high.

La presente Invention a - pour objet une Prise de courant comportant un socle en ma- tiere isolante Sur lequel sont montees des pieces de contact femelles, reliees chacune electriquement ä une Borne. Cette Prise de courant tend ä obvier aux inconvenients cites par 1e fait quo chaque piece de contaet forme, avec sa Borne et la connexion los reliant l'une ä 1'autre, un enseinble partiel, par 1e fait quo RTI ID="0001.0271" WI="11" HE="4" LX="1017" LY="1733"> ehacun de ces ensembles partiels est uruni d'organes de retenue cooperant avee des faces de retenue amenagees Sur 1e socle et par 1e Fait quo des moyens darret sont prevus, inter- disant aux Organes de retenue d'echapper aux faces de retenue. The subject of the present invention is a power outlet comprising a base of insulating material on which are mounted female contact parts, each electrically connected to a terminal. This Power Outlet tends to obviate the drawbacks cited by the fact that each piece of contact forms, with its Terminal and the connection los connecting one to the other, a partial assembly, by the fact that RTI ID="0001.0271" WI="11" HE="4" LX="1017" LY="1733"> each of these partial assemblies is provided with retaining members cooperating with retaining faces arranged on the first base and by the first fact quo means stop are provided, prohibiting the Retaining Organs from escaping the retaining faces.

Le dessin annexe montre, schematiquement et ä, titre d'exemple, une forme d.'execution de la Prise de courant objet de 1'invention et quelques pieces accessoires. The appended drawing shows, schematically and by way of example, one form of execution of the socket object of the invention and some accessory parts.

Les fig. 9 et 10 sont des vues de dessus de deux prises de courant dont l'une est equipee d'un neutre selon les anciennes norines, tan- dis que 1'autre est eqizipee d'un neutre selon les nouvelles prescriptions. Figs. 9 and 10 are top views of two socket outlets, one of which is equipped with a neutral according to the old standards, while the other is equipped with a neutral according to the new prescriptions.

Selon 1e dessin annexe, la Prise de courant comprend un socle 1 de preference en c6rami- que, deux pikes de contact 2 destinees ä etre reliees aux deux pöles du reseau de dist.ribu- tion, une pike de contact 3 destink ä eire reliee ä la terre et un couverele 4 fixe SurJe socle ä 1'aide dune vis 5 engagee dass un ecrou 6 loge dans 1e soele 1. According to the appended drawing, the power socket comprises a base 1 preferably in ceramic, two contact pins 2 intended to be connected to the two poles of the distribution network, a contact pin 3 intended to be connected to the earth and a cover 4 fixed on the plinth by means of a screw 5 engaged in a nut 6 lodged in the base 1.

Le socle presente la forme generale Tun eylindre circulaire dont deux Segments sont enleves. Les faces a etb de ces Segments sont approximativement paralleles, mais Prrne est environ deux fois plus grande que Pautre. Deux evidements lateraux 7, disposes suivant un plan diametral parallele aux faces a et b du socle et comportant chacun une face d'ap- pui 8, sont destines ä recevoir des Organes de fixation (non representes) permettant de fixer 1e socle Sur une paroi par exemple, leurs tetes prenant appui Sur les faces B. The base has the general shape of a circular cylinder from which two segments are removed. The faces a andb of these Segments are approximately parallel, but Prrne is about twice as large as the other. Two lateral recesses 7, arranged along a diametral plane parallel to faces a and b of the base and each comprising a support face 8, are intended to receive fastening members (not shown) allowing the base to be fixed on a wall. for example, their heads resting on the B sides.

Chaque pike de contact 2 comporte deux faces de serrage 9 portees par les bras elasti- ques dune Partie 10 en forme d'epingle ä cheveux. L'une desdites faces de serrage pre- sente La forme dune Partie de cylindre evase ä Pune de ses extremites, tandis que Pautre est plane. La Partie 10 Porte deux Organes de retenue 11 s'etendant lateralement. Chaque piece de contaet est reliee par tiiie connexion 19 ä une plaquette d'appui 12 constituant Tune des Parties dune Borne. Cette plaquette d'appui est munie de deux ailes et presente un percage taraude 13 dans lequel est enga- gee une vis 14 portant une plaquette de ser- rage 15. Each contact pin 2 has two clamping faces 9 carried by the elastic arms of a part 10 in the shape of a hairpin. One of said clamping faces has the shape of a flared cylinder part at one of its ends, while the other is flat. Part 10 carries two Retainers 11 extending laterally. Each contact piece is connected by a third connection 19 to a support plate 12 constituting one of the Parts of a Terminal. This support plate is provided with two wings and has a tapped hole 13 in which is engaged a screw 14 carrying a clamping plate 15.

La plaquette d'appizi Porte encore irn Or gane de retenue 16 constitue par un bee Porte par un bras 17 dispose äangle droit par rap- port ä cette plaquette 12. Enfin, cette der- niere est encore munie d'un Organe de retenue et de guidage 18. Ainsi, la pike de contact est venue de fabrication dune Beule pike avec ses Organes de retenue, une Partie de sa Borne avec Bon Organe de giiidage et la connexion la reliant ä sa Borne. La fabrication de l'en- semble partiel ainsi forme ne necessite que des operations de decoupage, pliage et. cam- brage, qui sont des-operations rapides et peu onereuses. Un Beul taraudage doit eire effec- tue pour la mise en place de la vis 14 rreces- saire au serrage des conducteurs dans la Borne. The appizi plate still carries a retaining member 16 constituted by a bee carried by an arm 17 placed at a right angle with respect to this plate 12. Finally, the latter is also provided with a retaining member and guide 18. Thus, the contact pike came from the manufacture of a Beule pike with its Retaining Organs, a Part of its Terminal with Good Giiidage Organ and the connection connecting it to its Terminal. The manufacture of the partial assembly thus formed requires only operations of cutting, bending and. bending, which are quick and inexpensive operations. A single thread must be made for the installation of the screw 14 required for tightening the conductors in the Terminal.

Cette pike de contact est placee dann un logement 20 pratique dann la face superieure du soele 1. Les Organes de retenue sont en- gages saus des faces d'appui 21 amenagees Sur Je socle, tandis que 1e bras 17, 1e bec 16 et 1'organe de guidage 18 sont engages dans des evidements 22 et 23 de formes correspon- dantes, 1e bec 16 et 1'organe 18 kant engages saus des faees de retenue 24. Enfin, 1'extre- mite libre de la vis 14 emergeant du percage taraii,de 13 est engagee dans un trau borgne 25 pratique dans 1e soele, Bette extremite de vis constitue un Organe d-'arret interdisant aux Organes de retenue d'echapper aux faces de retenue. This contact pike is placed in a practical housing 20 in the upper face of the base 1. the guide member 18 are engaged in recesses 22 and 23 of corresponding shapes, the spout 16 and the member 18 being engaged without retaining faees 24. Finally, the free end of the screw 14 emerging from the drilling taraii, 13 is engaged in a blind trau 25 practice in the first soele, Bette end of screw constitutes a Organ d-'arrest prohibiting the Retaining Organs to escape the retaining faces.

La pike de contaet 3 comporte deiix faces, de serrage 26 en forme de Partie de cylindre evase ä l'une de ses extremites, portees par deux paires de bras 27 relies ä des ponts 28 et 29. Le pont 28 presente un pereage 30 des tin6 ä la fixation par rivetage d'un doigt de mise ä la terre (non represente). Le pont 29 constitue une plaquette d'appui et presente an percage taraude Jans lequel est engagee une vis 14 munie Tune plaquette de serrage 15. La plaquette d'appui 29 Porte encore un bras 31 muni de deux organes de retcnue 32 engages dann un evidement 33 de forme cor- respondante, pratique dann 1e soele, tandis que 1e pont 28 poste un doigt 34 de guidage et de retenue, engage dans un evidement 35 pratique dann 1e socle 1. L'extremite libre de la vis 14 emergeant du percage taraude est engagee dann un trou borgne pratique dans 1e socle. Cette extremite de vis constitue un or- gane darret interdisant aux organes de re- tenue d'echapper aux faces de retenue. The contact pin 3 has two clamping faces 26 in the form of a flared cylinder part at one of its ends, carried by two pairs of arms 27 connected to bridges 28 and 29. The bridge 28 has a bore 30 of the tin6 to the fixing by riveting of an earthing finger (not shown). The bridge 29 constitutes a support plate and has a Jans tapped hole which is engaged with a screw 14 provided with a clamping plate 15. The support plate 29 still carries an arm 31 provided with two retaining members 32 engaged in a recess 33 of corresponding shape, practical in the first floor, while the bridge 28 posts a finger 34 for guiding and retaining, engaged in a recess 35 practical in the first base 1. The free end of the screw 14 emerging from the drilling taps is engaged in a convenient blind hole in the base. This end of the screw constitutes a stop member preventing the retaining members from escaping from the retaining faces.

Le montage normal de la Prise de courant cleerite est celui represente par les fig. 1 ä 4. La Prise de courant est alors munie de trois pieces de eontact femelles, tandis que la fiche eomportera trois pikes de contact mäles, dont les positions relatives sont representees ä la fig. 10. Cette Prise de courant correspond alors aux conditions et exigences imposees par les plus recents reglements. Par contre, en rivant un doigt de mise ä la terre dans 1e percage 30 et en munissant le socle d'un cou- verele pourvu dune ouverture en regard de ee doigt, an obtient une Prise de eourant re- pondant aux exigences des anciennes pres- criptions qui sont encore en vigueur. Enfin, les pieces de contact 2 peuvent etre rnunies d'un cache 37 autorisant seulement 1'engage- ment de fiches comportant des doigts de sec- tion rron circulaire. The normal mounting of the cleerite power socket is that shown in figs. 1 to 4. The power socket is then provided with three female contact pieces, while the plug will have three male contact pins, the relative positions of which are shown in fig. 10. This Socket then corresponds to the conditions and requirements imposed by the most recent regulations. On the other hand, by riveting an earthing finger in the hole 30 and by providing the base with a cover provided with an opening facing this finger, an outlet is obtained that meets the requirements of the old regulations. - stipulations which are still in force. Finally, the contact parts 2 can be provided with a cover 37 allowing only the engagement of plugs comprising fingers of circular section.

La mise en place de la fiche Sur la Prise de courant est tres aisk, car chaque pike de eontact femelle presente une extremite evasee facilitant 1'engagement de la Partie mäle portee par la fiche. De plus, les organes de retenrre, les fa.ces de retenue, ]es moyens dar- ret ainsi que chaque logement destine ä. rece- voir un ensemble forme dune pike de con- iact relik ä sa Borne par une connexion sont prevrrs de maniere ä permettre des dAplace- ments relatifs de faible amplitude (1 ä 2 mm) entre chaqrie ensemble et 1e socle. Ainsi, les pieces de contact femelles portees par 1e socle 1 peuvent aisement venir se placer dans 1e prolongement des pikes de contact mäles portees par la fiche. The installation of the plug on the power socket is very easy, because each female contact pin has a flared end facilitating the engagement of the male part carried by the plug. In addition, the organs of retenrre, the retaining fa.ces] are means dar- ret and each housing intended ä. receiving an assembly in the form of a contact pin connected to its Terminal by a connection are provided in such a way as to allow relative displacements of small amplitude (1 to 2 mm) between each assembly and the base. Thus, the female contact pieces carried by the first base 1 can easily be placed in the extension of the male contact pins carried by the plug.

L'une des Bornes extremes peut eire relik ä la Borne de mise ä la terre par un shunt 38 eomportant deux Parties 39 munies chacune d'un percage 40 et destinks ä etre serrees sous les plaquettes de serrage 15 des Bornes. One of the end Terminals can be connected to the Earthing Terminal by a shunt 38 comprising two Parts 39 each provided with a bore 40 and intended to be tightened under the clamping plates 15 of the Terminals.

Des pikes auxiliaires 41, 42, munies cha- cune dune Borne et dune Partie destink ä etre serree sous les plaquettes de serrage 15, permettent de realiser une Prise de courant av ec Bornes accessibles de 1'arriere. Ces pikes auxiliaires comportent ehacirne un doigt d'ap- pui 43 prenant appui Sur la face inferieure du socle 1 afin d'interdire une deformation de la pike auxiliaire lors du serrage d'un conducteur dann sa Borne. Auxiliary pegs 41, 42, each provided with a Terminal and a Part intended to be tightened under the clamping plates 15, make it possible to produce a Power Outlet with Terminals accessible from the rear. These auxiliary pegs each have a support finger 43 resting on the lower face of the base 1 in order to prevent deformation of the auxiliary peg when tightening a conductor in its terminal.

Gräce ä la grande elasticite qu'il est possi- ble de conferer aux bras e1astiques des pikes de contaet, il est possible d'utiliser les memes ensembles partiels pour les fiches munies de doigts de 4 mm et pour les ficlres munies de doigts de 5 mm de diametre, ce qui presente egalement un grand av antage par rapport aux prises de courant connues. Thanks to the great elasticity which it is possible to confer on the elastic arms of the contact pins, it is possible to use the same partial assemblies for the plugs fitted with 4 mm fingers and for the cables fitted with 5 mm fingers. mm in diameter, which also has a great advantage over known sockets.

Enfin, cette Prise de courant ne comporte aucune pike serree Sur 1e socle ou fixee rigi- dement Sur celui-ei, en Sorte que son mon- tage se compose uniquement d'operations simples et rapides. En fait, 1e montage dune telle prise,de courant se resume ä la pose des ensembles partiels Jans leur logement, au vis- sage des vis 14 et ä la mise en place de 1'ecrou 6 qui est serti dans son logement. Finally, this power socket does not have any pike tightened on the base or rigidly fixed on the latter, so that its assembly consists only of simple and rapid operations. In fact, the assembly of such a power socket is reduced to the installation of the partial assemblies in their housing, to the screwing of the screws 14 and to the positioning of the nut 6 which is crimped in its housing.

D'autre pari, cette Prise de courant per met tous les montages desires ä 1'aide de pattes, Supports, Plaques de fixation, etc., de. types connus et dejä utilises aetuellement pour 1'installation de prises de courant mri- rales encastrees, Sur panneaux, etc. On the other hand, this power socket allows all the desired assemblies using legs, brackets, fixing plates, etc., of. known types already in use for the installation of recessed socket outlets, on panels, etc.;

Comme represente ä la fig. 4, 1e couver- cle 4 est muni de nervures 44 formant chi- canes entre les pikes de contact. Ce couver- cle peut evidemment etre remplace par une protection lorsque la Prise de courant est en castr6e ou fixee Sur un panneau. As represented in fig. 4, the cover 4 is provided with ribs 44 forming baffles between the contact pins. This cover can of course be replaced by a protection when the power socket is castrated or fixed on a panel.

En variante, chaque pike de contact pour- " rait etre reliee ä sa Borne par u.ne piece de connexion, de manière à former des ensembles partiels assemblés par rivetage, par exemple, et munis, d'une part, d'organes de retenue destinés à coopérer avec des faces de retenue aménagées sur le socle et, d'autre part, de moyens d'arrêt. Ces organes de retenue, faces de retenue et moyens d'arrêt doivent évidem ment être prévus et agencés de manière à maintenir chaque ensemble partiel en position sur le socle sans nécessiter de serrage ou de scellement et autoriser un certain déplace ment relatif favorisant la mise en place de la fiche sur la prise de courant. Alternatively, each contact pin could be connected to its Terminal by a connection piece, so as to form partial assemblies assembled by riveting, for example, and provided, on the one hand, with retainers intended to cooperate with retainer faces provided on the base and, on the other hand, stop means.These retainers, retainer faces and stop means must obviously be provided and arranged in such a way as to maintain each partial assembly in position on the base without requiring tightening or sealing and allowing a certain relative movement favoring the positioning of the plug on the socket.
