Abstract

The edge connector socket clip comprises a single metal strip folded into the desired doubled-back shape in the conventional manner. Each side of the clip has a pair of longitudinal slots cut in it, each with an opening at the upper end. When the metal is bent the sections delimited by the slots are forced away from the rest of the clip outer faces. The clip walls converge to knees (6) which form a constriction past which the inserted plate of the male connector move. The separated central sections have their upper ends bent (5) so as to clip into the openings formed in the faces and also forming edges which bear against the underside of the connector housing (2), thus lodging the clip firmly in place. The upper ends (4) are bent over to grip the top faces of the housing where they can be soldered into place. Contact with the inserted plate at four points is achieved.

Description

Clips perfectionnés pour connexion de languettes plates sur circuit imprimé.Improved clips for connection of flat tabs on printed circuit.

L'invention est relative aux pinces de contact, dites "clips", pour connexion de languettes plates sur circuit imprimé. The invention relates to contact clips, called "clips", for connection of flat tabs on a printed circuit.

Plus précisément, elle concerne les clips antérieurement connus réalisés à partir d'un plat métallique en forme de pinces élastiques destinées à être insérées par poussée dans des orifices rectangulaires ménagés dans la plaque du circuit, les extrémités de la pince recourbées vers l'extérieur viennent ainsi en butée sur la face supérieure de la plaque et sont raccordées par soudure au circuit; des bossages symétriques externes, espacés des rebords extrêmes d'une distance légèrement supérieure à l'épaisseur de la plaque du circuit, viennent s' appuyer élastiquement contre les rebords inférieurs des orifices rectangulaires pour assurer un bon maintien en position correcte du clip avant soudure; enfin, les parties médianes en regard des deux branches sont rapprochées l'une de l'autre pour constituer la zone de pincement de la languette plate, et cette zone de pincement, pour garder une élasticité suffisante à la pince, se trouve nécessairement assez éloignée de la face supérieure de la plaque à partir de laquelle on embroche les languettes plates. More specifically, it relates to the previously known clips made from a metal dish in the form of elastic clamps intended to be inserted by pushing into rectangular holes formed in the circuit plate, the ends of the clamp bent outwards come thus in abutment on the upper face of the plate and are connected by welding to the circuit; symmetrical external bosses, spaced from the extreme edges by a distance slightly greater than the thickness of the circuit plate, come to bear elastically against the lower edges of the rectangular orifices to ensure good retention of the clip in correct position before welding; finally, the middle parts opposite the two branches are brought closer to each other to constitute the nip area of the flat tongue, and this nip area, to keep sufficient elasticity with the pliers, is necessarily quite distant of the upper face of the plate from which the flat tabs are inserted.

Les clips de ce type ont donc l'inconvénient d'interdire l'utilisation de composants dont la longueur des languettes plates de connexion est relativement courte. Clips of this type therefore have the drawback of prohibiting the use of components whose length of the flat connection tabs is relatively short.

L'invention a pour but principal d'éliminer cet inconve- nient. The main object of the invention is to eliminate this drawback.

A cet effet, l'invention a pour objet un clip du type décrit ci-dessus réalisé à partir d'un plat métallique en forme de pince élastique à deux branches assurant les deux fonctions, d'une part de maintien en position du clip dans un orifice de la plaque du circuit et, d'autre part, de pincement d la languette plate, caractérisé en ce que les branches comportent des découpes longitudinales de façon à constituer côte à côte dans chaque branche des éléments séparé s conformés pour assurer lesdites deux fonctions, les éléments assurant la fonction de pincement étant positionnés pour pouvoir être situés à proximité de la face inférieure de la plaque du circuit. To this end, the subject of the invention is a clip of the type described above produced from a metal dish in the form of an elastic clamp with two branches ensuring the two functions, on the one hand holding the clip in position. an orifice of the circuit board and, on the other hand, of pinching the flat tongue, characterized in that the branches have longitudinal cutouts so as to constitute, side by side in each branch, separate elements shaped to ensure said two functions, the elements ensuring the pinching function being positioned so that they can be located near the underside of the circuit board.

A titre d'exemples, on décrira ci-après quelques modes différents de réalisation de l'invention. By way of examples, a few different embodiments of the invention will be described below.

On se reportera au dessin annexé, sur lequel
La figure 1 représente en coupe un clip antérieurement connu,
Les figures 2 et 3 représentent, respectivement en coupe et de face, une première réalisation,
Les figures 4 et 5 représentent, respectivement en coupe et de face, une seconde réalisation, et
Les figures 6 et 7 représentent, respectivement en coupe et de face, une troisième réalisation.Reference is made to the appended drawing, on which
FIG. 1 represents in section a previously known clip,
FIGS. 2 and 3 show, respectively in section and from the front, a first embodiment,
FIGS. 4 and 5 show, respectively in section and from the front, a second embodiment, and
Figures 6 and 7 show, respectively in section and from the front, a third embodiment.

La figure 1 représente, en coupe, un clip connu réalisé par conformation d'un plat métallique en forme de pince élastique. Cette pince vient se loger par poussée dans un orifice rectangulaire 1 d'une plaque 2 de circuit. Une soudure 3 raccorde les extrémités 4 de la pince recourbées vers l'extérieur aux éléments conducteurs du circuit. Des bossages symétriques externes 5 viennent s'appuyer élastiquement contre les bords inférieurs des orifices 1 pour assurer le maintien en place du clip avant soudure. Les parties médianes en regard 6 de la pince, rapprochées l'une de l'autre, et nécessairement assez éloignées de la plaque 2 pour garantir l'élasticité de la pince, constituent la zone de pincement de la languette plate 7, représentée juste avant la fin de 1' opération d'embrochage. Figure 1 shows, in section, a known clip made by shaping a metal dish in the form of elastic clamp. This clamp is housed by pushing in a rectangular orifice 1 of a circuit plate 2. A weld 3 connects the ends 4 of the clamp bent outwards to the conductive elements of the circuit. Symmetrical external bosses 5 come to bear elastically against the lower edges of the orifices 1 to ensure that the clip is held in place before welding. The facing middle parts 6 of the clamp, brought closer to each other, and necessarily far enough from the plate 2 to guarantee the elasticity of the clamp, constitute the nip area of the flat tongue 7, shown just before the end of the racking-in operation.

Les figures 2 et 3 représentent, respectivement en coupe et de face, un premier mode de réalisation d l'invention. Comme on le voit sur la figure 3, les branches latérales de la pince comportent des découpes longitudinales 8. Cela permet de constituer côte à côte dans chaque branche des éléments conformés séparés lO-lo-12,assurant en combinaison entre eux les deux fonctions distinctes de maintien en position du clip avant soudure, et de pincement de la languette. Figures 2 and 3 show, respectively in section and from the front, a first embodiment of the invention. As seen in Figure 3, the side branches of the clamp have longitudinal cutouts 8. This allows to build side by side in each branch of separate shaped elements lO-lo-12, ensuring in combination between them the two distinct functions holding the clip in position before welding, and pinching the tongue.

Dans cette réalisation, les découpes 8 permettent d'avoir longitudinalement de chaque côté deux branches 10-10 de la pince se rejoignant pour former les extrémités recourbées 4 de la pince, puis les parties médianes rapprochées 6 remontées vers la face inférieure de la plaque. Les découpes 8 permettent par ailleurs de conformer les bossages 5 dans la partie centrale 12 des branches de la pince. Ces bossages 5, recourbés vers l'intérieur de la pince pénètrent dans un évidement 9 du plat.In this embodiment, the cutouts 8 make it possible to have longitudinally on each side two arms 10-10 of the clamp joining together to form the curved ends 4 of the clamp, then the close-together median parts 6 raised towards the underside of the plate. The cutouts 8 also make it possible to conform the bosses 5 in the central part 12 of the arms of the clamp. These bosses 5, bent towards the inside of the clamp penetrate into a recess 9 of the plate.

Incidemment, on observe que l'invention permet d'obtenir ainsi quatre points de contact, dans la zone de pincement 6, au lieu de deux dans les clips antérieurement connus. Incidentally, it is observed that the invention thus makes it possible to obtain four contact points, in the pinching zone 6, instead of two in the previously known clips.

Les figures 4 et 5 concernent une seconde réalisation encore plus simple. Les découpes longitudinales 8, visibles fig. 5, permettent l'obtention des mêmes caractéristiques fonctionnelles que dans le cas précédent, c'est-à-dire que les branches latérales 10 assurent la fonction de pincement tandis que les branches centrales 12 assurent la fonction de maintien. Figures 4 and 5 relate to a second even simpler embodiment. The longitudinal cuts 8, visible in fig. 5, allow the obtaining of the same functional characteristics as in the previous case, that is to say that the lateral branches 10 provide the pinching function while the central branches 12 provide the holding function.

Les figures 6 et 7 concernent une réalisation un peu différente. Ici, les découpes longitudinales 8 évident complètement la partie centrale 14 de la pince. Des flancs latéraux 16 à bords inclinés 18 et 20 sont découpés dans le plat métallique de la pince. Dans ce cas, lorsque l'on met en place le clip, c'est l'élasticité de la partie centrale 22 de la pince qui permet la mise en place du clip, par glissement du bord 20 sur l'orifice 1 de la plaque, et son maintien en position, par application du bord i8 sur la base de l'orifice. Figures 6 and 7 relate to a slightly different embodiment. Here, the longitudinal cutouts 8 completely visible the central part 14 of the clamp. Side flanks 16 with inclined edges 18 and 20 are cut from the metal plate of the clamp. In this case, when the clip is put in place, it is the elasticity of the central part 22 of the clamp which allows the clip to be put in place, by sliding the edge 20 over the orifice 1 of the plate. , and maintaining it in position, by applying the edge i8 to the base of the orifice.

Les flancs latéraux 16 assurent ici la même fonction.que les bossages 5 des premier et second mode de réalisation.The lateral flanks 16 here perform the same function as the bosses 5 of the first and second embodiment.

D'autres modes de réalisation sont possibles pour mettre en application l'idée inventive consistant à conformer longitudinalement côte à côte dans les branches du clip des éléments distincts conformés assurant les deux fonctions de maintien en place du clip, et de pincement de la languette plate rapprochée de la plaque du circuit  Other embodiments are possible for implementing the inventive idea consisting in longitudinally conforming side by side in the branches of the clip separate shaped elements ensuring the two functions of holding the clip in place, and pinching the flat tongue. close to the circuit board
