Abstract

The rectangular socket has one part (2) for coupling with the male pin and one part (3) for fixing to the electric wire on which the part (2) is seated. The coupling part is formed from a plate which is bent at four corners making a rectangle one of whose sides has two folds which overlap partially to form an angle of about three degrees with the vertical giving the part elasticity for the introduction of the male pin.S The opening of the socket (4) has a flare (5) which forms an angle of about five degrees with the longitudinal axis of the socket, facilitating the introduction of the male pin. Clamping of the socket on the pin is provided by a boss set between the socket and the pin.

Description

L'invention a pour objet une douille rectangulaire pour cordons de raccordement d'appareils électriques. The invention relates to a rectangular socket for connection cords of electrical devices.

Ces pièces métalliques sont surmoulées ou tout simplement montées dans des fiches. These metal parts are overmolded or simply mounted in sheets.

Ces pièces doivent permettre une entrée facile des broches mâles tout en permettant un bon contact électrique et sans que lesdites broches puissent sortir inopinément. These parts must allow easy entry of the male pins while allowing good electrical contact and without the said pins being able to come out unexpectedly.

Ces douilles doivent donc permettre une entrée des broches, un peu en force avec des parois un peu souples. De plus, il est nécessaire que l'entrée soit parfaitement plane pour les douilles qui doivent être surmoulées de manière à éviter ainsi que de la matière ferme ou recouvre même partiellement l'entrée. These sockets must therefore allow entry of the pins, somewhat in force with somewhat flexible walls. In addition, it is necessary that the entry is perfectly flat for the sockets which must be overmolded so as to avoid as well as firm material or even partially covering the entry.

Les douilles actuelles présentent ces différents inconvénients techniques notamment de grands risques d'infiltration de matière plastique au moment du surmoulage. Current sockets have these various technical drawbacks, in particular great risks of infiltration of plastic material during overmolding.

L'invention évite tous ces inconvénients. The invention avoids all these drawbacks.

La douille selon l'invention est rectangulaire au niveau de la partie d'emmanchement et de contact avec la borne mâle. Elle est formée par une plaque qui est repliée en quatre plis et dont un des côtés comporte deux plis que se recouvrent partiellement et forment un angle o( faible de l'ordre de trois degrés avec la verticale, pour assurer une élasticité à l'ensemble de cette partie de la douille . Tout en étant rigoureusement plane, l'ouverture de la douille comporte une partie évasée qui forme avec l'axe longitudinal de la douille un angle ,ss voisin de quinze degrés qui facilite l'introduction de la broche mâle. The socket according to the invention is rectangular at the level of the fitting part and of contact with the male terminal. It is formed by a plate which is folded in four folds and one of the sides of which has two folds that partially overlap and form an angle o (small on the order of three degrees with the vertical, to ensure elasticity to the assembly of this part of the socket. While being strictly planar, the opening of the socket has a flared part which forms an angle with the longitudinal axis of the socket, ss close to fifteen degrees which facilitates the introduction of the male pin .

Les figures ci-jointes données à titre d'exemple indicatif et non limitatif permettront aisément de comprendre l'invention. Elle représentent un mode de réalisation préféré selon l'invention. The attached figures given by way of indicative and non-limiting example will easily allow the invention to be understood. They represent a preferred embodiment according to the invention.

La figure 1 est une vue de côté de la douille rectangulaire. Figure 1 is a side view of the rectangular socket.

La figure 2 est une vue de la douille, vue de dessus à plat. Figure 2 is a view of the socket, seen from above flat.

La figure 3 est une vue en bout de ladite douille. Figure 3 is an end view of said socket.

La douille 1 est composée d'une partie d'emmanchement 2 avec la broche mâle et d'une partie de fixation 3 avec le fil électrique, sur lequel ladite partie est sertie. The sleeve 1 is composed of a fitting part 2 with the male pin and a fixing part 3 with the electric wire, on which said part is crimped.

L'ouverture 4 de la douille 1 comporte un évasement 5 qui facilite l'introduction de la broche mâle non représenté sur les figures. The opening 4 of the sleeve 1 has a flare 5 which facilitates the introduction of the male pin not shown in the figures.

Sur la figure 2 les parties en pointillé 14 et 15 indiquent l'endroit où sera coupée l'attache 6 au moment du sertissage. In Figure 2 the dotted parts 14 and 15 indicate the location where the clip 6 will be cut at the time of crimping.

Dans la figures 3 on comprend comment la partie 2 est repliée en quatre coins 7, 8, 9 et 10. Un des côtés 11 comporte deux plis 12 et 13 qui se recouvrent de manière à donner de 1 ' élasticité à la pièce. In Figures 3 we understand how the part 2 is folded into four corners 7, 8, 9 and 10. One of the sides 11 has two folds 12 and 13 which overlap so as to give elasticity to the part.

Eventuellement, un verrouillage de la douille 1 sur la broche peut être prévu afin d ' augmenter sensiblement la tenue mécanique de l'assemblage douille sur broche, ledit verrouillage pouvant être composé par exemple d'un jeu de bossage entre ladite douille et la broche. Cette réalisation n'est pas représentée sur les figures. Optionally, a locking of the socket 1 on the spindle can be provided in order to substantially increase the mechanical strength of the socket on spindle assembly, said locking being able to be composed for example of a boss game between said socket and the spindle. This embodiment is not shown in the figures.
