Il comprend deux branches perpendiculaires creuses en matériau élastomère, dont une première branche est destinée à recevoir un câble avec à son extrémité une partie excentrée apte à être insérée dans une partie de cavité de forme correspondante du connecteur et une seconde branche apte à recevoir un conducteur dont l'extrémité est vissée dans cette partie d'extrémité du câble.It comprises two hollow perpendicular branches of elastomeric material, a first branch of which is intended to receive a cable with at its end an eccentric part adapted to be inserted into a correspondingly shaped cavity portion of the connector and a second branch capable of receiving a conductor whose end is screwed into this end portion of the cable.

Le montage d'un tel connecteur sur un câble est effectué en utilisant de la graisse de lubrification et est relativement complexe.The mounting of such a connector on a cable is performed using lubricating grease and is relatively complex.

Selon l'ajustement du câble à l'intérieur du connecteur et selon la quantité de graisse appliquée, l'installateur doit maintenir fermement le corps du connecteur, afin d'éviter que ce dernier se repousse du câble, avant que le vissage du conducteur soit réalisé.Depending on the fit of the cable inside the connector and depending on the amount of grease applied, the installer must hold the connector body firmly to prevent the connector from pushing back against the cable before the driver's screw is tightened. realized.

Le câble est ainsi retenu longitudinalement et peut aisément rester en place, sans nécessité de retenue manuelle, et le second conducteur peut aisément être vissé.The cable is thus retained longitudinally and can easily remain in place, without the need for manual restraint, and the second conductor can easily be screwed.

The dielectric layer 5B of the cable is here surrounded by a dielectric coupling sheath 5C commonly called cable reducer.

L'adaptateur 6 fait saillie radialement du câble 5 équipé de la gaine diélectrique d'adaptation 5C et la bride de blocage 4 est disposée en butée contre la surface d'extrémité de l'adaptateur 6 tournée vers la gaine diélectrique d'adaptation 5C et vers la couche diélectrique 5B.The adapter 6 protrudes radially from the cable 5 equipped with the dielectric adapter sheath 5C and the locking flange 4 is placed in abutment against the end surface of the adapter 6 facing the dielectric adapter sheath 5C and to the dielectric layer 5B.

Sur cette figure 2, le second conducteur 8, de préférence une tige ou une broche de contact, est en cours d'installation.On this figure 2 , the second conductor 8, preferably a rod or a contact pin, is being installed.

L'adaptateur conducteur excentré 6 est également représenté en détail sur les figure 3 à 5.The eccentric driver adapter 6 is also shown in detail on the figure 3 to 5 .

L'adaptateur 6 cylindrique présente un méplat longitudinal 6A portant un orifice fileté 6B dans lequel est vissée l'extrémité du second conducteur 8.The cylindrical adapter 6 has a longitudinal flattening 6A carrying a threaded orifice 6B into which is screwed the end of the second conductor 8.

L'équipement du connecteur 1 s'effectue de la manière suivante.The equipment of the connector 1 is carried out as follows.

L'extrémité du câble 5 est dénudée de sa couche diélectrique 5B pour laisser l'extrémité du conducteur 5A libre et la gaine diélectrique d'adaptation 5C est disposée à cette extrémité.

The end of the conductor 5A is introduced into the longitudinal cavity of the adapter 6 and is fixed there by screwing the radial stud 7.

Le câble ainsi équipé de son adaptateur 6 est introduit dans la première branche 1A dans une seule position possible compte-tenu de la forme de la cavité de l'insert 2B en élastomère conducteur et de l'excentricité de cet adaptateur 6.The cable thus equipped with its adapter 6 is introduced into the first branch 1A in a single possible position taking into account the shape of the cavity of the insert 2B conductive elastomer and the eccentricity of the adapter 6.

Suite à ses dimensions et à l'élastomère qui est un matériau rigide d'une dureté de de l'ordre de 78 Shore A et d'une résistance à la traction de l'ordre de 12,7 MPa, la bride 4 tout comme l'extrémité de l'insert 2B en élastomère conducteur peut se déformer élastiquement au passage de l'adaptateur qui est ainsi disposé dans la position représentée dans la figure 2, où la bride 4 vient se loger en butée contre la surface d'extrémité 6A1 du méplat 6A de l'adaptateur.Due to its dimensions and to the elastomer which is a rigid material with a hardness of about 78 Shore A and a tensile strength of about 12.7 MPa, the flange 4 just as the end of the insert 2B conductive elastomer can deform elastically to the passage of the adapter which is thus disposed in the position shown in the figure 2 , where the flange 4 is housed in abutment against the end surface 6A1 of the flat part 6A of the adapter.

Le câble ainsi retenu peut aisément rester en place, sans nécessité de retenue manuelle, et le second conducteur peut être vissé dans l'orifice fileté 6B de l'adaptateur.The retained cable can easily remain in place without the need for manual restraint, and the second conductor can be screwed into the threaded hole 6B of the adapter.
