Abstract

The wire-stripping contactor consists of a metal profiled channel in which the wire is gripped, and a plastic cap which guides the wire prior to insertion. Wires of different diameters can be accommodated. The channel (11) is of rectangular section and has two or more pairs of tapering side wings (12a,13a,12b, 13b,12c,13c) which are bent inwards towards its axis. The ends of the wings leave gaps (a,b,c) in the centre of the channel which decrease along the direction of entry of the wire. The arrangement ensures that at least one pair of side wings will be of the correct spacing to pierce the wire insulation and grip the conducting core when the wire is held in the device. To form the connection, the wire is inserted into the plastics cap. The cap has a profiled recess corresponding to the variation of width in the channel sections and allows the wire to be correctly positioned in the channel when the cap is snap-fastened to the latter.

Description

La présente invention a pour objet un perfectionnement aux éléments de contact électrique d connexion autodénudante pour fiil ou câble décrits dans le brevet principal et dans le premier certificat d'addition nO 78 26527 du 05/09/1978. La présente addition s'applique sans exception a tous les modes de réalisation du brevet principal et de la première addition et en particulier 9 toutes les revendications de ces deux titres. The subject of the present invention is an improvement to the electrical connection elements for insulation displacement connection for wire or cable described in the main patent and in the first certificate of addition No. 78 26527 of 05/09/1978. This addition applies without exception to all the embodiments of the main patent and the first addition and in particular all the claims of these two titles.

Le brevet principal et la première addition ont pour objet un élément de contact électrique à connexion autodénudante pour fil ou câble, ayant la forme générale d'un profilé a section en forme d'un U et comportant des moyens de contact obtenus par découpage et pliage de parties des ailes du profilé, les moyens de contact comportant au moins une paire de'languettes planes découpées de préférence chacune dans une des parois du profilé, et de préférence symétriquement l'une en regard de l'autre et pliées vers l'intérieur du profilé selon un angle aigu de façon que le bord libre desdites languettes morde le conducteur formant l'âme du cible ou fil à raccorder, de façon qu'une traction sur le câble ou fil provoque un effet de coincement par rapprochement des languettes, pour s'opposer a l'arrachement du câble ou fil, grace a la rigidité en compression des languettes dans leur plan. La forme et la fonction de ces paires de languettes évoquent des "portes d'écluses".  The main patent and the first addition concern an electrical contact element with an insulation displacement connection for wire or cable, having the general shape of a U-shaped section section and comprising contact means obtained by cutting and folding. parts of the wings of the profile, the contact means comprising at least one pair of planar tongues preferably each cut into one of the walls of the profile, and preferably symmetrically facing one another and folded inwards the profile at an acute angle so that the free edge of said tongues bite the conductor forming the core of the target or wire to be connected, so that a pull on the cable or wire causes a wedging effect by bringing the tabs together, for oppose the tearing of the cable or wire, thanks to the compressive rigidity of the tongues in their plane. The shape and function of these pairs of tongues evoke "lock gates".

Conformément à la présente invention, l'élément de contact comporte au moins deux paires de languettes présentant des intervalles différents entre les bords des languettes des différentes paires, les intervalles étant croissants vers l'extrémité du profilé a laquelle arrive le câble ou fil. According to the present invention, the contact element comprises at least two pairs of tongues having different intervals between the edges of the tongues of the different pairs, the intervals being increasing towards the end of the profile to which the cable or wire arrives.

L'invention a également pour objet un capuchon utilisable en combinaison avec l'élément de contact, servant d'outil d'insertion et d'extraction, et de protection du contact. The invention also relates to a cap that can be used in combination with the contact element, serving as a tool for insertion and extraction, and for protecting the contact.

D'autres caractéristiques de l'invention apparai- tront au cours de la description qui va suivre, donnée a titre d'exemple non limitatif en regard des dessins ci-joints et qui fera bien comprendre comment l'invention peut être réalisée. Other features of the invention will become apparent from the following description given by way of non-limiting example with reference to the accompanying drawings and which will make it clear how the invention can be realized.

Les dessins montrent

figure 6, une vue en élévation de l'élément de contact des figures 1 à 4, garni d'un capuchon de protection; et
figure 7, une vue en coupe du capuchon de la figure 6, suivant la ligne VII-VIf,
L'élément de contact des figures 1 à 4 présente la forme générale d'un profilé 11 en forme de U (figure 3) dans les parois latérales duquel sont découpées trois paires de languettes 12a, 13a , 12, 13b , 12c, 13c.Les languettes sont repliées vers l'intérieur du profilé conformément au brevet principal. Elles peuvent aussi comporter avantageusement un chanfrein 15 de guidage. Conformément à la présente invention, les intervalles a, b, c (figure 1) entre les bords libres des languettes sont différents et vont en croissant vers l'extrémité 14 du profilé par laquelle arrive le câble à raccorder, extrémité que l'on désignera par la suite, extrémité d'entrée. Ainsi les intervalles a, b, c sont tels que a > b > c. Ceci est obtenu par le choix des dimensions des languettes et/ou par le choix des angles de pliage des languettes vers l'intérieur du profilé. Ceci permet de raccorder des conducteurs de différents diamètres à un même élément de contact.Sur la figure 2 on a représenté un câble 15 d'un diamètre correspondant à l'intervalle a et raccordé à la paire de languettes 12a,13a la plus proche de l'entrée 14 du contact.The drawings show
FIG. 1 is a view from above of a contact element according to the invention, the U-profile open towards the top.
FIG. 2, an elevational view of the same contact element
FIG. 3 is an end view along arrow III of FIG.
FIG. 4, a plan view of the developed element
FIG. 5, a view similar to FIG. 3 for a variant
Figure 6 is an elevational view of the contact element of Figures 1 to 4, provided with a protective cap; and
FIG. 7 is a sectional view of the cap of FIG. 6 along the line VII-VIf,
The contact element of Figures 1 to 4 has the general shape of a U-shaped profile 11 (Figure 3) in the side walls of which are cut three pairs of tongues 12a, 13a, 12, 13b, 12c, 13c. The tabs are folded towards the inside of the profile according to the main patent. They may also advantageously comprise a guiding chamfer. In accordance with the present invention, the intervals a, b, c (Figure 1) between the free edges of the tongues are different and are increasing towards the end 14 of the section through which the cable to be connected, end that will be designated subsequently, entrance end. Thus the intervals a, b, c are such that a>b> c. This is achieved by the choice of the dimensions of the tongues and / or by the choice of the folding angles of the tongues towards the inside of the profile. This makes it possible to connect conductors of different diameters to one and the same contact element. FIG. 2 shows a cable 15 having a diameter corresponding to the interval a and connected to the pair of tabs 12a, 13a closest to the input 14 of the contact.

Un câble plus fin passera sans contact galvanique entre les languettes 12a, 13a qui coopéreront à la rétention axiale du câble et sera raccordé entre les languettes 12b, 13b et un câble encore plus fin sera raccordé entre les languettes 12c, 13c. A l'extrémité opposée à l'entrée est formé un contact de sortie, par exemple au moyen de deux lamelles 17,18. A thinner cable will pass without galvanic contact between the tabs 12a, 13a which cooperate with the axial retention of the cable and will be connected between the tabs 12b, 13b and an even finer cable will be connected between the tabs 12c, 13c. At the end opposite the inlet is formed an output contact, for example by means of two strips 17,18.

La figure 4 représente à titre d'exemple un mode de découpage de l'élément de contact dans une feuille métallique. L'élément est formé par un pliage approprié. FIG. 4 represents, by way of example, a method of cutting the contact element in a metal foil. The element is formed by a proper folding.

Comme cela est expliqué dans le brevet principal, un élément de contact selon l'invention peut comporter deux rangées 12', 13' et 21,22 de paires de languettes comme représenté sur la figure 5. Cet exemple n'étant pas limitatif du nombre de rangées, les intervalles correspondants des deux rangées peuvent être les mêmes, ou des intervalles de la rangée supérieure peuvent être plus grands. D'une manière générale, toutes les caractéristiques prévues dans le brevet principal et la première addition peuvent être appliquées dans le cas présent. As explained in the main patent, a contact element according to the invention may comprise two rows 12 ', 13' and 21,22 pairs of tongues as shown in Figure 5. This example is not limiting the number of rows, the corresponding intervals of the two rows may be the same, or intervals of the upper row may be larger. In general, all the features provided for in the main patent and the first addition can be applied in the present case.

-Le nombre de paires de languettes est évidemment au moins égal à deux. I1 peut être de trois comme représenté, ou supérieur. The number of pairs of tongues is obviously at least equal to two. I1 can be three as represented, or higher.

Conformément à une autre caractéristique de la présente invention, l'élément de contact est utilisé en combinaison avec un capuchon de protection 23, qui sert d'outil d'insertion et d'extraction. Le capuchon a une forme de gouttières, permettant de recouvrir le profilé 11, avec des découpages latéraux 24 permettant aux lamelles de contact de venir s'encastrer.Le fond de la gouttière présente trois niveaux 25, 26, 27 auxquels correspondent des parois d'épaisseurs différentes 29, 30, 31 de façon a former trois sections libres différentes se succédant en diminuant de la droite vers la gauche. Ainsi, en introduisant un câble par l'extrémité évasée 37, on pourra l'engager et le faire avancer dans la gouttière jusqu'à ce que son extrémité butte sur une section inférieure à celle du câble.On a représenté à titre d'exemple sur la figure 7 un câble 39 pouvant passer dans les sections33 et 34, mais ne pouvant pas s'engager dans la section 35. Une fois le câble calé dans le capuchon, on vient placer celui-ci sur le profilé 11 pour l'amener dans la tosi- tion représentée sur la figure 6. Dans cet exemple, le contact sera réalisé entre les languettes 12b et 13b et les languettes 12a, 13a viendront coopérer a rétention axiale du fil. According to another feature of the present invention, the contact element is used in combination with a protective cap 23, which serves as an insertion and extraction tool. The cap has a shape of gutters, for covering the profile 11, with lateral cutouts 24 allowing the contact strips to be embedded.The bottom of the gutter has three levels 25, 26, 27 which correspond to the walls of different thicknesses 29, 30, 31 so as to form three different free sections succeeding each other by decreasing from right to left. Thus, by introducing a cable through the flared end 37, it can be engaged and advance in the gutter until its end abuts on a lower section than the cable.On has been represented by way of example in Figure 7 a cable 39 can pass in the sections33 and 34, but can not engage in section 35. Once the cable wedged in the cap, we just place it on the profile 11 to bring it In this example, the contact will be made between the tabs 12b and 13b and the tabs 12a, 13a will cooperate to axial retention of the wire.

Le-capuchon peut comporter tout moyen de fixation coopérant avec des moyens correspondants prévus sur le pro- filé tel aue des vis ou un encliauetase, Ces moyens sont bien connus en eux-mêmes, ils sont très variés et il n'est pas nécessaire de les représenter. Le capuchon peut également comporter des moyens de coincement du fil, en sens axial ou radial. The cap may comprise any means of attachment cooperating with corresponding means provided on the profile such as screws or an encliauetase, These means are well known in themselves, they are very varied and it is not necessary to represent them. The cap may also comprise means for jamming the wire, in axial or radial direction.

I1 va de soi que les modes de réalisation décrits ne sont que des exemples et qu'il serait possible de les modifier notamment par substitution d'équivalents techniques sans sortir pour celà du cadre de l'invention.  It goes without saying that the described embodiments are only examples and that it would be possible to modify them in particular by substitution of technical equivalents without departing from that of the scope of the invention.
