Description

Adaptateur pour générateur électrochimique aux dimensions extérieures non normalisées
La présente invention concerne un adaptateur pour générateur électrochimique aux dimensions extérieures non normalisées.Adapter for electrochemical generator with non-standardized external dimensions
The present invention relates to an adapter for an electrochemical generator with non-standardized external dimensions.

il est destiné notamment à équiper un accumulateur électrique cvlindrique, susceptible de remplacer une pile, et dont la configura- tion etérieure ne correspond pas à un format normalisé répondant aux normes CEI.  it is intended in particular to equip a cylindrical electric accumulator, capable of replacing a battery, and whose external configuration does not correspond to a standardized format meeting IEC standards.

On connaît un tel adaptateur décrit dans le brevet américain n0 30864 583. Il est constitué par une enveloppe cylindrique isolante aux dimensions extérieures normalisées et présentant intérieurement des nervures de blocage latéral de l'accumulateur. Les constituants de l'accumulateur sont logés dans un godet portant sur sa face supérieure une borne positive et dont le fond constitue une borne négative.There is known such an adapter described in US Patent No. 30,864,583. It is constituted by an insulating cylindrical envelope with standardized external dimensions and having internally lateral locking ribs of the accumulator. The constituents of the accumulator are housed in a cup carrying on its upper face a positive terminal and the bottom of which constitutes a negative terminal.

Le brevet prévoit d une part un élément de connexion négative constitué par un disque métallique en contact avec la borne négative et bloqué dans la partie inférieure de ladite enveloppe, et d'autre part un élément de connexion positive en forme de tube métallique bloquée dans une cheminée centrale appartenant au couvercle de l'enveloppe. The patent provides on the one hand a negative connection element constituted by a metal disc in contact with the negative terminal and blocked in the lower part of said casing, and on the other hand a positive connection element in the form of metal tube blocked in a central chimney belonging to the cover of the envelope.

La présente invention a pour but de réaliser un adaptateur plus simple et plus économique que l'adaptateur précédent.The present invention aims to achieve a simpler and more economical adapter than the previous adapter.

La présente invention a pour objet un adaptateur pour générateur élec trochimique aux dimensions extérieures non normalisées, ce générateur étant contenu dans un godet cylindrique dont la face supérieure porte une borne positive et dont le fond constitue une borne négative, ledit adaptateur comportant une enveloppe cylindrique isolante aux dimensions normalisées munie d'un fond et d'un couvercle et à l'inté rieur de laquelle est calé ledit générateur S ilil. est notamment carac- térisé par le fait que le fond de ladite enveloppe est ouvert de manière à laisser accessible ladite borne négative, qu'une capsule métallique est fixée sur la face supérieure dudit couvercle, que cette capsule est munie d'au moins un ergot traversant ce couvercle et relié par une connexion électrique à ladite borne positive.The subject of the present invention is an adapter for an electro-chemical generator with non-standardized external dimensions, this generator being contained in a cylindrical cup whose upper face carries a positive terminal and whose bottom constitutes a negative terminal, said adapter comprising a cylindrical insulating envelope with standard dimensions provided with a bottom and a cover and inside which is wedged said generator S ilil. is in particular characterized by the fact that the bottom of said envelope is open so as to leave accessible said negative terminal, that a metal capsule is fixed on the upper face of said cover, that this capsule is provided with at least one lug passing through this cover and connected by an electrical connection to said positive terminal.

Le blocage du godet dans ladite enveloppe est avantageusement assuré par le fond de l'enveloppe# des nervures internes latérales, et une nervure parallèle à l'axe du godet et solidaire de la face interne du couvelzele de 17 enveloppe. The blocking of the bucket in said envelope is advantageously ensured by the bottom of the envelope # of the lateral internal ribs, and a rib parallel to the axis of the bucket and integral with the internal face of the cover of the envelope.

Selon une première variante de réalisation, la paroi latérale et le couvercle de l'enveloppe sont deux pie ces indépendantes reliées entre elles par un procédé choisi parmi le soudage, l'encliquetage, le bouterollage.According to a first alternative embodiment, the side wall and the cover of the envelope are two independent parts linked together by a process chosen from welding, snap-fastening, snap-fastening.

Si cette solidarisation est effectuée par soudage par ultra-sons, l'extrémité de la nervure parallèle à l'axe du godet peut être soudée simultanément à la face supérieure de ce godet.If this joining is carried out by ultrasonic welding, the end of the rib parallel to the axis of the bucket can be welded simultaneously to the upper face of this bucket.

Selon une seconde variante de réalisation, la paroi latérale de 17enveloppe e; son couvercle forment une pic ce monobloc, tandis que son fond est suffisamment ouvert pour permettre le passage dudit godet.According to a second alternative embodiment, the side wall of 17envelope e; its cover forms a peak this one-piece, while its bottom is sufficiently open to allow the passage of said bucket.

D' autres caractéristiques et avantages de la présente invention âpparatront au cours de la description suivante faite à l'aide du dessin annexé donne à titre illustratif mals nullement limitatif et dans lequel - la figure 1 montre schématiquement en coupe partielle un adaptateur selon l'invention dans lequel est monté un accumulateur, - la figure 2 montre en vue de dessous le couvercle de l'adaptateur de la figure 1, - les figures 3, t. et 5 illustrent des phases du montage de l'acoumula- teur dans son adaptateur, - la figure 6 montre schématiquement une variante de réalisation de l'adaptateur de la figure 1. Other characteristics and advantages of the present invention will appear during the following description given with the aid of the appended drawing, which is non-limiting in illustration and in which - FIG. 1 schematically shows in partial section an adapter according to the invention in which is mounted an accumulator, - Figure 2 shows a bottom view of the adapter cover of Figure 1, - Figures 3, t. and 5 illustrate phases of mounting the accumulator in its adapter, - Figure 6 schematically shows an alternative embodiment of the adapter of Figure 1.

On voit dans les figures 1 et 2 un accumulateur électrique cylindrique muni de son godet métallique i, dont le fond 2 constitue une borne négative et dont la face supérieure 3 présente une borne centrale positive 4. Les dimensions extérieures de ce godet ne correspondent pas à un format normalisé CEI. C'est pourquoi on l'introduit dans une enveloppe en matière plastique 5 dont la forme et les dimensions répondent aux normes. Cette enveloppe présente un fond 24 ouvert et un couvercle 6#. Ce couvercle comporte une protubérance centrale 7 dont la base présente trois ouvertures 8, 9, 10. Cette protubérance est destinée à recevoir une capsule métallique 20 munie de trois ergots susceptibles de s' engager respectivement dans les ouvertures 8, 9, 10.We see in Figures 1 and 2 a cylindrical electric accumulator provided with its metal bucket i, the bottom 2 of which constitutes a negative terminal and the upper face 3 of which has a positive central terminal 4. The external dimensions of this bucket do not correspond to a standardized IEC format. This is why it is introduced into a plastic envelope 5 whose shape and dimensions meet the standards. This envelope has an open bottom 24 and a cover 6 #. This cover has a central protuberance 7, the base of which has three openings 8, 9, 10. This protuberance is intended to receive a metal capsule 20 provided with three lugs capable of engaging respectively in the openings 8, 9, 10.

(Bien entendu le nombre d'ergots et d'ouvertures peut être quelconque). L'un des ergots 21 est plus long que les autres ou il est soudé à une connexion électrique souple en vue d'être soudé à la borne positive 4.(Of course the number of pins and openings can be arbitrary). One of the lugs 21 is longer than the others or it is soldered to a flexible electrical connection in order to be soldered to the positive terminal 4.

Les figures 3, 4 et 5 montrent schématiquement le procédé de montage - On engage les ergots 21, 22 de la capsule 20 dans les ouvertures correspondantes (figure 3) - par un rabottage (ou un rivetage) on immobilise ces ergots contre la face interne du couvercle 6 (voir figure 4) - on soude l'ergot 21 à la borne 4 (voir figure 5) - on replie ensuite l'ergot 21 et on introduit l'ensemble dans l'enve- loppe 5 par le haut (voir figure 1). Une nervure 11 terminée en pointe 12 et formant une portion de cercle vient au contact de la face 3 du godet 1 et immobilise ce godet contre le fond 24. L'immobilisation latérale est assurée par plusieurs nervures de la face interne de l'enveloppe 5 ; seule la nervure 30 apparaît sur la figure 1.Figures 3, 4 and 5 schematically show the mounting process - We engage the pins 21, 22 of the capsule 20 in the corresponding openings (Figure 3) - by planing (or riveting) these pins are immobilized against the internal face of the cover 6 (see figure 4) - the lug 21 is welded to the terminal 4 (see figure 5) - the lug 21 is then folded back and the assembly is introduced into the envelope 5 from above (see figure 1). A rib 11 terminating in a point 12 and forming a portion of a circle comes into contact with the face 3 of the bucket 1 and immobilizes this bucket against the bottom 24. The lateral immobilization is ensured by several ribs on the internal face of the casing 5 ; only the rib 30 appears in FIG. 1.

La solidarisation des bords du couvercle et de l'enveloppe se fait par soudage, bouterollage ou enoliquetage. The edges of the cover and the enclosure are joined together by welding, gluing or polishing.

Lorsque l'on utilise un soudage, par exemple aux ultra-sons, la pointe 12 de la nervure 11 se trouve chauffée en même temps que les bords du couvercle 6 et de l'enveloppe 5 r il en résulte une fixation de cette nervure au niveau de la zone 25 de l'accumulateur.When welding, for example ultrasonic welding, the tip 12 of the rib 11 is heated at the same time as the edges of the cover 6 and of the envelope 5 r this results in attachment of this rib to the level of zone 25 of the accumulator.

On voit dans la figure 6 une variante de réalisation d'un adaptateur selon l'invention. FIG. 6 shows an alternative embodiment of an adapter according to the invention.

L'enveloppe 40 forme avec son couvercle une pièce unitaire s son fond 42 est suffisamment ouvert pour laisser le passage du godet 1.The envelope 40 forms with its cover a unitary piece s its bottom 42 is sufficiently open to allow passage of the bucket 1.

Le montage de la capsule 43 se fait de la même manière que celui de la capsule 20 de la#figure 1, l'ergot 41 étant toutefois choisi suffisamment long pour que l'on puisse appliquer le procédé de montage des figures 3 à 5.The mounting of the capsule 43 is done in the same way as that of the capsule 20 of # FIG. 1, the lug 41 being however chosen long enough so that the assembly method of FIGS. 3 to 5 can be applied.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation qui viennent d'être décrits. On pourra, sans sortir du cadre de l'invention remplacer tout moyen par un moyen équivalent. Of course, the invention is not limited to the embodiments which have just been described. Without departing from the scope of the invention, any means may be replaced by equivalent means.
