Description

La présente invention concerne un ensemble de connexion pour connecter un conducteur électrique à une cosse électrique mâle d'un dispositif électrique, un ensemble d'interconnexion comprenant un tel ensemble de connexion, une minuterie comportant un tel ensemble de connexion ou d'interconnexion, ainsi qu'un procédé de connexion pour connecter un conducteur électrique à une cosse électrique mâle d'un dispositif électrique.The present invention relates to a connection assembly for connect an electrical conductor to a male electrical lug of a electrical device, an interconnection assembly comprising such set of connection, a timer comprising such a set connection or interconnection and a connection method to connect an electrical conductor to a male electrical lug an electrical device.

L'invention concerne plus particulièrement un tel ensemble de connexion dans lequel lesdites cosses électriques mâles sont formées d'une lame en matériau électriquement conducteur, ledit ensemble comprenant au moins un organe de connexion en matériau également électriquement conducteur comportant au moins un orifice allongé de forme correspondant à une section transversale d'une cosse.The invention relates more particularly to such a set of connection in which said male electrical terminals are formed of a blade of electrically conductive material, assembly comprising at least one connecting member of material also electrically conductive having at least one orifice elongated shape corresponding to a cross section of a lug.

On connaít des dispositifs électriques, et plus particulièrement électromécaniques, pourvus de cosses électriques de montage et de connexion, par exemple dans le domaine des minuteries pour appareils électroménagers tels que lave-vaisselle, lave-linge ou sèche-linge.Electrical devices are known, and more particularly electromechanical devices, provided with electrical lugs for mounting and connection, for example in the field of timers for appliances such as dishwashers, washing machines or dryer.

Une telle cosse de montage et de connexion est constituée par une lame rigide en cuivre qui permet le montage de la minuterie sur un circuit imprimé recevant également les composants électroniques nécessaires au fonctionnement des différents moteurs ou électrovannes de l'appareil.Such a connection and connection lug is constituted by a rigid copper blade that allows the mounting of the timer on a printed circuit also receiving the electronic components necessary for the operation of the different engines or solenoid valves of the device.

Ces minuteries commutent dans le temps des lignes électriques connectées aux cosses de montage et de connexion dans différents états électriques. En général, ces états sont au nombre de trois, soit un inverseur avec une entrée et deux sorties et un état ouvert.These timers switch over time with power lines connected to the terminal lugs and connection in different electrical states. In general, these states are three in number, an inverter with one input and two outputs and one open state.

Les fabriquants d'appareils incorporant ces minuteries doivent relier les lignes aux cosses des minuteries. Pour diminuer le nombre de fils, on crée alors des ponts de liaison multiples pour les entrées ou sorties de la minuterie qui sont au même potentiel au même instant. Il s'agit des interconnexions. Manufacturers of devices incorporating these timers must connect the lines to the lugs of the timers. To decrease the number of wires, multiple link bridges are then created for the inputs or timer outputs that are at the same potential at the same moment. These are the interconnections.

On peut également être amené à connecter à une de ces cosses un fil d'alimentation pour le moteur de la minuterie.We may also have to connect to one of these lugs a power wire for the timer motor.

Plusieurs techniques sont actuellement utilisées pour effectuer ces connexions ou interconnexions.Several techniques are currently used to perform these connections or interconnections.

On peut en premier lieu utiliser des cosses femelles reliées entre elles par des fils conducteurs et montées sur les cosses mâles à interconnecter. Plusieurs fils peuvent être reliés à une même cosse femelle, ce qui permet des interconnexions multiples entre cosses mâles ainsi que des connexions de ces cosses à un circuit électrique. Cette solution présente l'inconvénient d'être onéreuse pour l'utilisateur.We can first use connected female pods between them by wires and mounted on the male terminals to interconnect. Several wires can be connected to one terminal female, which allows multiple interconnections between pods males as well as connections of these lugs to an electrical circuit. This solution has the disadvantage of being expensive for the user.

Il est également connu de réaliser les interconnexions à l'aide de pistes conductrices formées sur l'une des faces ou sur les deux faces du circuit imprimé précité, soudé sur les cosses. Cette solution est également onéreuse, notamment en temps de vérification de la soudure, lorsque le nombre de connexions à réaliser est faible.It is also known to realize the interconnections using conductive tracks formed on one or both sides faces of the aforementioned printed circuit, soldered on the terminals. This solution is also expensive, especially when checking the when the number of connections to be made is small.

Une autre solution consiste à réaliser les connexions à l'aide de ponts métalliques comportant des orifices dans lesquels les cosses à relier sont engagées à force. L'inconvénient est ici de former des rayures sur les parties de connexion des cosses, ce qui interdit l'utilisation de connecteurs du type à enfichage doux car, la pression de contact étant faible, les rayures empêchent un bon contact entre le connecteur et la cosse.Another solution is to make connections using metal bridges having orifices in which the lugs connect are forcibly engaged. The disadvantage here is to form scratches on the connecting parts of the terminals, which prohibits the use of plug-in type connectors because the pressure contact is weak, scratches prevent good contact between the connector and the terminal.

Afin d'éviter ce dernier inconvénient, on a également proposé d'utiliser des ponts métalliques qui pincent le bord de la cosse pour éviter, dans la mesure du possible, de rayer la zone centrale de raccordement. Toutefois, les contacts entre le pont et les cosses sont alors ponctuels, de sorte que, pour des courants forts, il est nécessaire d'empiler plusieurs ponts de ce type.In order to avoid this last disadvantage, it has also been proposed to use metal bridges that pinch the edge of the pod for avoid, as far as possible, the removal of the central zone of connection. However, the contacts between the bridge and the pods are then punctual, so that for strong currents it is necessary to stack several bridges of this type.

Le document US-A-4 567 654 présente un ensemble selon le préambule de la revendication 1.US-A-4,567,654 discloses a set according to the preamble of claim 1.

La présente invention vise à pallier ces inconvénients.The present invention aims to overcome these disadvantages.

A cet effet, l'invention a tout d'abord pour objet un ensemble de connexion pour connecter un conducteur électrique à une cosse électrique mâle d'un dispositif électrique, ladite cosse étant formée d'une lame en matériau électriquement conducteur et ledit ensemble comprenant au moins un organe de connexion en matériau électriquement conducteur comportant au moins un orifice allongé de forme correspondant à une section transversale d'une cosse, caractérisé par le fait que ladite cosse possède une surépaisseur sur au moins une de ses faces dans sa partie la plus éloignée de son extrémité libre et que les dimensions dudit orifice sont telles que ledit organe de connexion s'engage avec jeu sur l'extrémité libre de la cosse et de façon serrée sur ladite surépaisseur.For this purpose, the invention firstly relates to a set of connection to connect an electrical conductor to a pod male electrical device, said terminal being formed of a blade of electrically conductive material and said assembly comprising at least one connecting member made of material electrically conductive having at least one elongated shape corresponding to a cross section of a lug, characterized in that said pod has an extra thickness on at least one of its faces in its farthest part of its free end and that the dimensions of said orifice are such that said connecting member engages with play on the free end of the pod and tightly on said overthickness.

L'extrémité libre de la cosse constitue la zone de raccordement pour l'utilisateur du dispositif électrique, par exemple de la minuterie. Du fait que l'organe de connexion s'engage avec jeu sur cette zone, aucune rayure n'est à craindre. Ce n'est que lorsque l'organe de connexion arrive dans la zone de la cosse la plus éloignée de son extrémité libre qu'il rencontre la surépaisseur sur laquelle il peut alors s'accrocher.The free end of the lug constitutes the connection zone for the user of the electrical device, for example the timer. Since the connection member engages with play on this zone, no scratches are to be feared. Only when the connection arrives in the area of the pod the farthest from his free end that it meets the extra thickness on which it can then hang on.

Dans un mode de réalisation particulier, ladite surépaisseur possède une forme allongée dans le sens longitudinal de la cosse.In a particular embodiment, said overthickness has an elongate shape in the longitudinal direction of the pod.

Egalement dans un mode de réalisation particulier, ladite surépaisseur possède une épaisseur croissante à partir de son bord le plus proche de l'extrémité libre de la cosse.Also in a particular embodiment, said overthickness has an increasing thickness from its edge closest to the free end of the pod.

Le serrage de l'organe de connexion sur la cosse est ainsi progressif. On assure en particulier un bon contact entre l'organe de connexion et la cosse, qui se fait d'une part sur toute la largeur de la face de la cosse opposée à la surépaisseur, ainsi que sur une certaine largeur de cette surépaisseur du fait d'une déformation du bord de l'orifice de l'organe de connexion. On évite donc la nécessité d'utiliser plusieurs organes de connexion superposés.The tightening of the connection member on the lug is thus progressive. In particular, good contact is ensured between the organ of connection and the pod, which is on the one hand across the width of the opposite of the thimble opposite the overthickness, as well as on a certain width of this extra thickness due to a deformation of the edge of the orifice of the connecting member. We therefore avoid the need to use several superposed connection members.

Ladite surépaisseur peut être formée d'un embouti et correspond alors à un creux sur la face opposée de la cosse.Said overthickness may be formed of a stamp and then corresponds to a hollow on the opposite side of the pod.

On observera qu'un tel ensemble de connexion peut être utilisé soit pour l'interconnexion de deux cosses mâles, soit pour la connexion d'une cosse mâle à un fil, par exemple pour l'alimentation d'un moteur de minuterie.It will be observed that such a connection set can be used for the interconnection of two male terminals, or for the connection of a male lug to a wire, for example for feeding a timer engine.

L'invention a donc également pour objet un ensemble tel que décrit ci-dessus dans lequel ledit organe de connexion comporte des moyens pour sertir un conducteur électrique.The invention therefore also relates to a set such that described above in which said connection member comprises means for crimping an electrical conductor.

L'invention a également pour objet un ensemble d'interconnexion pour connecter entre elles des cosses électriques mâles d'un dispositif électrique, caractérisé par le fait qu'il comprend au moins deux ensembles de connexion tels que décrits ci-dessus, les organes de connexion des deux ensembles étant réalisés d'une seule pièce.The subject of the invention is also a set interconnection to interconnect electrical lugs males of an electrical device, characterized in that it comprises at least two connection sets as described above, the connecting members of the two assemblies being made of a single piece.

L'invention a également pour objet une minuterie, notamment pour appareil électroménager, caractérisée par le fait qu'elle comprend des cosses électriques munies d'ensembles de connexion ou d'interconnexion tels que décrits ci-dessus.The invention also relates to a timer, in particular for household appliances, characterized by the fact that includes electrical terminals with connection sets or interconnection as described above.

L'invention a également pour objet un procédé pour former un ensemble pour connecter un conducteur électrique à une cosse électrique mâle d'un dispositif électrique, ladite cosse étant formée d'une lame en matériau électriquement conducteur, ledit procédé comportant l'étape consistant à former au moins un organe de connexion en matériau électriquement conducteur comportant au moins un orifice allongé de forme correspondant à une section transversale d'une cosse, caractérisé par le fait qu'il comprend en outre les étapes consistant à emboutir ladite cosse pour former une surépaisseur sur une de ses faces dans sa partie la plus éloignée de l'extrémité libre de la cosse, et à former lesdits orifices de manière que leur dimension soit telle que l'organe de connexion s'engage avec jeu sur l'extrémité libre de la cosse et de façon serrée sur ladite surépaisseur.The invention also relates to a method for forming an assembly for connecting an electrical conductor to a male electrical terminal of a device electrical, said lug being formed of a blade of material electrically conductive, said method comprising the step of forming at least one connecting member of material electrically conductive having at least one elongated shape corresponding to a cross section of a lug, characterized by further comprising the steps of stamping said lug to form an extra thickness on one of its faces in its farthest part of the free end of the pod, and forming said orifices so that their dimension is such that the connection member engages with play on the free end of the pod and tightly on said overthickness.

We will now describe, by way of non-limiting example, particular embodiments of the invention, with reference to the appended diagrammatic drawings in which:
  • Figure 1 is a partial cross-sectional view of a timer provided with connection assemblies according to the invention;
  • Figure 2 is a much larger scale view of a portion of such a timer;

  • Figure 6 is a sectional view on a larger scale of the detail VI of Figure 4; and
  • Figures 7a to 7d are perspective views illustrating the method according to the invention.

On voit à la figure 1 une minuterie 1 comportant de façon connue dans un boítier 2, une pluralité de leviers 3, 4, 5 montés respectivement sur des axes de rotation 6, 7, et 8.FIG. 1 shows a timer 1 comprising known in a housing 2, a plurality of levers 3, 4, 5 mounted respectively on axes of rotation 6, 7, and 8.

Ces leviers comportent des doigts suiveurs de came 9, 10 et 11. Les doigts suiveurs de came 9, 10 et 11 coopèrent avec des cames tournantes non représentées entraínées en rotation par un moteur électrique de façon connue.These levers comprise cam follower fingers 9, 10 and 11. The cam follower fingers 9, 10 and 11 cooperate with rotating cams, not shown, driven in rotation by a electric motor in a known manner.

A une extrémité opposée aux doigts suiveurs de came 9, 10 et 11, les leviers 3, 4, 5 comportent des ergots de manoeuvre 12, 13 et 14 agencés pour coopérer avec des lames de contact élastiques 15, 16 et 17 respectivement.At an end opposite the cam follower fingers 9, 10 and 11, the levers 3, 4, 5 have operating pins 12, 13 and 14 arranged to cooperate with elastic contact blades 15, 16 and 17 respectively.

La minuterie 1 comporte par ailleurs un certain nombre de cosses mâles 18 montées de façon fixe de toute manière convenable, solidaires du boítier 2. Chaque lame de contact 15, 16 et 17 a une de ses extrémités reliées de façon fixe à une des cosses 18 et son autre extrémité est munie d'un contact 19, 20 sur chacune de ses faces, agencé pour coopérer avec un contact correspondant formé sur chacune des cosses en vis-à-vis.Timer 1 also includes a number of male lugs 18 fixedly mounted in any suitable manner, integral with the housing 2. Each contact blade 15, 16 and 17 has one of its ends connected in a fixed manner to one of the terminals 18 and its other end is provided with a contact 19, 20 on each of its faces, arranged to cooperate with a corresponding contact formed on each of the pods opposite.

A titre d'exemple, on voit à la figure 1 le levier 3 dans une position telle que la lame de contact 15 est en situation élastiquement relâchée de sorte qu'elle assure le contact électrique entre la cosse 181 à laquelle est reliée son extrémité fixe et une cosse 182.For example, we see in Figure 1 the lever 3 in a position such that the contact blade 15 is in situation elastically released so that it provides electrical contact between the terminal 181 to which is connected its fixed end and a pod 182.

Dans une autre position du levier 3, le contact d'extrémité de la lame 15 se trouverait dans une position intermédiaire entre la cosse 182 et la cosse 183 adjacente de sorte que le circuit serait ouvert. C'est la situation dans laquelle se trouve la lame de contact 16.In another position of the lever 3, the end contact of the blade 15 would be in an intermediate position between the pod 182 and the adjacent lug 183 so that the circuit would be open. This is the situation in which the contact blade 16 is located.

Enfin, dans une troisième position du levier 3, la lame de contact 15 serait dans un état de contrainte maximum et assurerait la connexion entre la cosse 181 et la cosse 183. C'est la situation de la lame de contact 17. Finally, in a third position of the lever 3, the blade of contact 15 would be in a state of maximum restraint and would ensure the connection between lug 181 and lug 183. This is the situation of the contact blade 17.

Les figures 3 à 6 représentent à grande échelle une cosse 18.Figures 3 to 6 represent a large scale pod 18.

Cette cosse est réalisée dans une lame de laiton rigide de forme généralement rectangulaire allongée.This pod is made of a rigid brass blade of generally elongated rectangular shape.

L'extrémité libre de la cosse 18 est effilée en 21 pour permettre un engagement aisé d'une cosse femelle correspondante. La cosse 18 comporte par ailleurs deux renfoncements 22 pour permettre son montage sur un face 23 du boítier 2.The free end of the lug 18 is tapered in 21 to allow easy engagement of a corresponding female lug. The pod 18 has two recesses 22 to allow its mounting on a face 23 of the housing 2.

La cosse 18 comporte également, dans sa partie transversale médiane, un embouti 24 formant une surépaisseur 25 sur une de ses faces et un creux 26 sur son autre face.The lug 18 also has, in its transverse part median, a stamp 24 forming an extra thickness 25 on one of his faces and a hollow 26 on its other face.

La partie de la surépaisseur 25 la plus proche de l'extrémité libre 21 de la cosse 18 possède une épaisseur qui croít à partir de son début le plus proche de cette extrémité 21. On voit à la figure 6 le plan incliné 27 (en fait sensiblement un demi-tronc de cône) par lequel la surépaisseur 25 se raccorde à la surface de la cosse 18.The part of the overthickness 25 closest to the end free 21 of the pod 18 has a thickness that increases from its beginning nearest this end 21. We see in Figure 6 the inclined plane 27 (in fact substantially a half-truncated cone) by which the excess thickness 25 is connected to the surface of the lug 18.

On voit enfin sur les figures 3 et 4 le contact électrique 28 de la cosse, formé d'un embouti 29 réalisé simultanément à l'embouti 24, recouvert du côté où il est en relief d'un métal de contact 30.Finally we see in Figures 3 and 4 the electrical contact 28 of the pod, formed of a stamp 29 made simultaneously stamped 24, covered on the side where it is embossed with a contact metal 30.

On décrira maintenant les connexions entre une cosse 18 et un conducteur d'alimentation, ainsi que les interconnexions entre cosses 18.We will now describe the connections between a lug 18 and a supply conductor, as well as the interconnections between pods 18.

On voit à la figure 7b un certain nombre de modes de réalisation d'organes d'interconnexion 31 selon l'invention, susceptibles de coopérer avec des cosses mâles 32 telles que celles de la figure 7a.We see in Figure 7b a number of modes of embodiment of interconnection members 31 according to the invention, likely to cooperate with male pods 32 such as those of Figure 7a.

Les cosses 32 sont disposées selon un agencement matriciel en lignes et colonnes.The pods 32 are arranged in a matrix arrangement in rows and columns.

Les organes d'interconnexion 31 sont constituées par des lames conductrices découpées telles que la lame 33 comportant deux orifices allongés 34 de forme correspondant généralement à la section transversale d'une cosse 32. Les deux orifices 34 sont ici parallèles et côte à côte transversalement.The interconnection members 31 are constituted by blades cut conductors such as the blade 33 having two elongated orifices 34 of shape generally corresponding to the cross section of a lug 32. The two orifices 34 are here parallel and side by side transversely.

Les dimensions d'un orifice 34 sont telles que l'organe de connexion 31 s'engage avec jeu sur l'extrémité libre de la cosse 32 et de façon serrée sur la surépaisseur 25. The dimensions of an orifice 34 are such that the organ of connection 31 engages with play on the free end of the terminal 32 and tightly on the overthickness 25.

D'autres formes d'organes d'interconnexion sont représentées à la figure 7b.Other forms of interconnecting devices are represented in Figure 7b.

Par exemple, l'organe 35 possède trois orifices 36 pour trois cosses mâles, mais qui sont ici alignés par rapport à leur dimension longitudinale.For example, the member 35 has three orifices 36 for three male pods, but which are here aligned with respect to their size longitudinal.

Dans le cas de l'organe 37, les orifices 38 sont formés en quinconce.In the case of the member 37, the orifices 38 are formed in staggered.

Bien entendu, toute autre combinaison, notamment des cas précédents, peut être envisagée.Of course, any other combination, including cases precedents, can be considered.

On voit également à la figure 7b des organes de connexion 39 entre une cosse et un fil conducteur électrique. Un tel organe de connexion comporte comme les organes d'interconnexion précédemment décrits un orifice allongé 40, ainsi que des ailes 41 susceptibles par repliement d'assurer le sertissage d'un conducteur électrique non représenté.FIG. 7b also shows connection members 39 between a pod and an electrical conductor wire. Such a body of connection has like the interconnecting devices previously described an elongate orifice 40, as well as wings 41 likely by folding to ensure the crimping of a driver electric not shown.

Les figures 7a à 7b illustrent les différentes étapes d'un procédé permettant le montage des organes de connexion qui viennent d'être décrits sur l'ensemble des cosses électriques mâles 32.Figures 7a to 7b illustrate the different steps of a method for mounting the connecting members which have just been described on the set of male electrical lugs 32.

Ce montage utilise une plaque intermédiaire isolante 42 et un gabarit 43.This assembly uses an insulating intermediate plate 42 and a template 43.

La plaque intermédiaire 42 comporte des orifices 44 permettant un montage glissant des cosses 32 dans la partie d'extrémité de ces dernières, puis un serrage sur les surépaisseurs 25. Un orifice est prévu pour chaque cosse.The intermediate plate 42 has orifices 44 allowing a sliding mounting of the pods 32 in the end portion of these last, then a tightening on the extra thicknesses 25. An orifice is provided for each pod.

La plaque intermédiaire 42 est pourvue par ailleurs de renfoncements tels que 45 dans lesquels peuvent être disposés les organes d'interconnexion 31 ou de connexion 39. Des découpes 46 sont prévues pour faire communiquer avec l'extérieur les renfoncements destinés à recevoir les organes de connexion 39, de manière à permettre le passage des moyens de sertissage 41 et des fils souples.The intermediate plate 42 is also provided with recesses such as 45 in which can be arranged the interconnection members 31 or connection 39. Cutouts 46 are planned to communicate with the outside the recesses for receiving the connecting members 39, to allow the passage of the crimping means 41 and the soft threads.

Les renfoncements 45 peuvent comporter plusieurs étages tels que 47 et 48 pour recevoir plusieurs organes de connexion ou d'interconnexion superposés tels que 35 et 49 respectivement. The recesses 45 may comprise several stages such 47 and 48 to receive several connection members or interconnect interconnects such as 35 and 49 respectively.

Le gabarit 43 comporte également des renfoncements 50 permettant de recevoir d'autres organes de connexion ou d'interconnexion tels que 51.The template 43 also has recesses 50 to receive other connection devices or interconnection such as 51.

Le montage de l'ensemble qui vient d'être décrit s'effectue de la manière suivante.The assembly of the assembly which has just been described is carried out from the following way.

Les organes de connexion 31 et d'interconnexion 39 sont tout d'abord mis en place dans leurs renfoncements respectifs 45 de la plaque intermédiaire 42. Le sous-ensemble ainsi constitué est ensuite engagé sur les cosses 32 jusqu'à la position de butée représentée à la figure 1.The connection members 31 and interconnection 39 are all first set up in their respective recesses 45 of the intermediate plate 42. The subset thus formed is then engaged on the terminals 32 to the stop position shown in Figure 1.

Les organes 51 sont ensuite disposés dans leurs renfoncements 50, après quoi le gabarit 43 est à son tour engagé sur les cosses 32.The members 51 are then arranged in their recesses 50, after which the template 43 is in turn engaged on the pods 32.

Enfin, le gabarit 43 est retiré, laissant en place les organes 51, la plaque intermédiaire 42 et les organes 31 et 39.Finally, the template 43 is removed, leaving the members 51 in place, the intermediate plate 42 and the members 31 and 39.

Les organes 31, 39 et 51 sont maintenus en place du fait des surépaisseurs des cosses 32 qui sont ajustées de façon serrée dans les orifices tels que 34 et 36. De plus, les organes tels que 51 retiennent la plaque intermédiaire 42.The members 31, 39 and 51 are held in place because of the thicknesses of the pods 32 which are tightly adjusted in the orifices such as 34 and 36. In addition, the organs such as 51 retain the intermediate plate 42.

Dans un autre mode de mise en oeuvre du procédé de montage, on commence par placer les organes de connexion 31 dans le gabarit 43, puis la plaque 42 est mise en place. On met ensuite en place les connexions 31 dans la plaque 42, et le minuteur avec ses cosses 32 est engagé dans l'ensemble ainsi réalisé.In another embodiment of the mounting method, we begin by placing the connection members 31 in the template 43, then the plate 42 is put in place. Then we put in place connections 31 in the plate 42, and the timer with its terminals 32 is engaged in all so realized.

On observera que le montage avec jeu de la plaque intermédiaire sur les parties d'extrémité des cosses 32 puis le serrage sur les surépaisseurs permet à lui seul le maintien mécanique. Il fournit également une isolation électrique entre les organes de connexion.It will be observed that the assembly with play of the plate intermediate on the end portions of the pods 32 and then the tightening on the overthickness alone allows the maintenance mechanical. It also provides electrical insulation between connecting members.

On notera également que la plaque intermédiaire pourrait être plane, c'est-à-dire ne pas comporter les renfoncements 45. Le moule de fabrication de la plaque en serait d'autant simplifié, mais ce serait au détriment de l'isolation entre les organes de connexion, qui ne seraient plus séparés que par de l'air.It should also be noted that the intermediate plate could be flat, that is to say do not include the recesses 45. The mold plate making would be all the more simplified, but it would be to the detriment of the insulation between the connecting members, which does not would be more separated than by air.
