Definitions
- connection device electric of the type comprising at least one terminal intended to be fixed on a support and means of pod rotation.
- the invention aims to provide a device for electrical connection which eliminates above-mentioned drawbacks of known devices and to get the same result as these in a way very simple and therefore economical.
- the connecting device electric according to the invention is characterized in that the anti-rotation means include integrated means to the terminal, adapted to cooperate with the means provided on the support, as defined in claim 1.
- the anti-rotation means are arranged so as to only allow a limited number of positions.
- a terminal according to the invention has a flat shape, advantageously circular, which comprises at at least one notch formed at its periphery, and at least one stud is provided on the bearing face of the terminal on the support, and intended to come into contact with an edge side of the notch.
- Figure 1 is a top view of a device for electrical connection according to the invention.
- Figure 2 is a sectional view along line II-II of the support of the device according to FIG. 1.
- Figures 3 to 6 show the terminal according to Figure 1 in different positions.
- a device for electrical connection comprises a terminal 1 intended to be fixed on a support 2 using a clamping screw 3 (figure 2).
- the terminal is cut from a metal strip and has a flat and circular shape. It includes a connection zone 3 for fixing the conductor electric, which protrudes radially from the part circular, this connection being made for example by crimping. At the periphery of the terminal are provided two notches 5 and 6 of different angular length which are separated by the bonding area or area of crimping 3.
- the means anti-rotation include two pads 8 which are angularly separated by a distance slightly greater than the width of the crimping area 3 for allow the engagement of this crimping area between the two studs, as shown in Figures 4 and 5.
- the notch 5 has a slightly angular length. greater than the angular difference between the radial flanks 10 of the studs, which are distant from each other, thus allowing the engagement of the two studs ( Figure 3).
- the notch 6 has a length slightly greater than the width of a stud to allow the reception of a single stud, as shown in Figures 4 and 5.
- the bearing surface of the terminal is in relief, that is to say overhanging its immediate environment and its dimensions are such that the connection zone 3 is outside this surface when the terminal is in place. This allows the mounting of the pod in any direction without there interference between link area 3 and the environment of the bearing surface because the area of bond is generally not symmetrical with respect to plan of the pod.
- Figure 1 shows yet another embodiment of terminal 1, which is shown in broken lines and that in the middle of notch 5 such that shown in solid lines, an extension is planned radial 11 extending just between the two studs anti-rotation 8.
- a third embodiment it would be possible to only plan on the outskirts of the circular part as the radial extension 11.
- Terminal 1 can be mounted in only two positions, depending on the direction of mounting.
- Figures 3 and 4 show mounting on the support with crimping on top of the terminal, while Figures 5 and 6 show the mounting with crimping on the underside. So the shape of the terminal combined with the two anti-rotation pads 8 only allows two positions for a mounting direction of the terminal given.
- the terminal of the invention has a very simple and easy form, therefore economical, to manufacture and is not aggressive to the support face of the support due to its flat shape.
- the edges 12 and 13 forming the edges of the notches 5 and 6 respectively are radiated, i.e. that their end is slightly rounded so that there is no sharp angle at their junction with the peripheral edge of the terminal. Congestion of means is reduced due to the presence of only two anti-rotation pads, which are simple to machine.

Description
Claims (10)
- Dispositif de raccordement électrique, du type comprenant au moins une cosse destinée à être fixée sur un support à l'aide d'une vis de serrage et des moyens d'antirotation de la cosse (5, 6 ; 11 ; 8) comprenant au moins une découpe (5, 6) pratiquée dans la cosse (1) et coopérant avec au moins un plot (8) prévu sur le support (2) et disposé de façon à pouvoir s'engager dans ladite découpe, caractérisé en ce que ladite découpe (5, 6) est formée par une encoche (5, 6) ménagée à la périphérie de la cosse, et en ce que la cosse présente une forme extérieure telle que, lorsque le plot (8) n'est pas engagé dans l'encoche (5, 6), la périphérie de la cosse vienne en butée lors d'une mise en place de la cosse sur le plot si bien que cette mise en place soit empêchée.
- Dispositif selon la revendication 1, caractérisé en ce que la cosse présente une forme circulaire coaxiale au trou de passage de la vis de serrage.
- Dispositif selon la revendication 2, caractérisé en ce que la cosse 1 comprend deux encoches (5, 6) séparées par une zone en saillie radiale (3) servant de zone de sertissage de la cosse.

- Dispositif selon la revendication 4, caractérisé en ce que l'autre encoche de la cosse (1) a une largeur adaptée pour la réception d'un seul plot (8).
- Dispositif selon l'une des revendications 2 à 4, caractérisé en ce que la cosse présente une excroissance radiale (11) destinée à s'engager entre deux plots (8) sur la face d'appui (9) du support (2).
- Dispositif selon l'une des revendications précédentes caractérisé en ce que les cosses sont réalisés par découpage à partir d'une bande métallique.
- Dispositif selon l'une des revendications précédentes, caractérisé en ce que les moyens d'antirotation (5, 6 ; 11 ; 8) sont agencés de manière à n'autoriser qu'un nombre limité de positions de la cosse sur la face d'appui (9) du support (2).
- Dispositif selon la revendication 7, caractérisé en ce que le nombre de positions possibles est égal à deux.
- Dispositif selon l'une des revendications 7 ou 8, caractérisé en ce que les moyens d'antirotation (5, 6 ; 11 ; 8) sont agencés pour n'autoriser que le nombre désiré de positions possibles quel que soit le sens de montage de la cosse (1) sur le support (2).
