Definitions

• the invention relates to a modular electrical connector, and in particular an electrical power connector made up of modular connection elements to be arranged as required.
• the invention aims to improve these modular electrical connectors, in particular for power transmission.
• a modular electrical connector in particular for power transmission, comprising at least one male connector element and a corresponding female connector element, characterized in that each of the corresponding connector elements comprises a body identical insulator, this body comprising an axial bore receiving the contact element, male or female, and at least two transverse drilling holes perpendicular to said bore, by which it can be threaded on complementary rods and fixed to constitute a modular assembly of 'connector elements, the assemblies of male and female connector elements being shaped in correspondence to allow them to be plugged in or axially disabled.
• Said insulating body advantageously has a rectangular parallelepiped conformation and said holes are arranged laterally at the base of the body and in the same plane perpendicular to the axial bore, so that the connector elements can be assembled in line on the rods and the lines connector elements can themselves be supported fixed on bars transverse to the lines, allowing an assembly of connector elements on a plane, with connection correspondence of the assemblies of male and female connector elements in plan.
• Said body comprises on each of its assembly faces, at least one projection and a shaped recess complementary, at a distance from each other.
• This projection and this recess are received respectively in a recess and a complementary projection of the adjacent body face. They are intended to allow the interlocking of two adjacent bodies and ensure their assembly positioning by limiting the assembly clearance.
• a third interlocking point for example a projecting element (lug) of a face coming in a complementary recess of an adjacent face, can be provided on each of the assembly faces so as to position precisely in volume. said interlocking assembly of connector element bodies.
• Said projection may consist of an annular shoulder formed axially on the edge of a drilling hole.
• a complementary recess is therefore formed on the opposite assembly face of the body.
• an assembly face of a body fits on the assembly face of an adjacent body, at three points arranged in a triangle to allow rigorous positioning in line and in plan of the assembly of the connector elements. , which must be found in a relatively precise correspondence to allow the insertion of an assembly of male connector elements in an assembly of opposite female connector elements.
• insulating flanges can be placed between said connector elements, in order to increase the length of the current creepage line between two adjacent or neighboring connector elements, or possibly allow coding from one connector to another.
• the body further comprises an annular shoulder threaded at its upper part, coaxial with the bore and allowing the connection with a cable tie clamp.
• An annular recess is provided on the opposite opposite face, for mounting a contact sealing ring, which, mounted on one of the body recesses, is received in a sealed manner in the opposite annular recesses two connector elements corresponding to the plug-in.

• FIG. 5 is a view of an alternative embodiment showing an assembly of connector elements on the surface, on fixing bars.
• FIG. 1 A modular in-line connector according to the invention is shown in FIG. 1. This connector results from a linear assembly of two corresponding sets 1 of connector elements, male 3 and female 5 respectively, intended to be inserted one at a time. the other or cutters according to arrow, respectively, by engagement of the male contact elements 7 in the corresponding female elements 9.
• the lower set 1 of female contact is fixed integral with a support element 11, thus corresponding to the base of the connector and the upper male set 1 is movable, corresponding to the plug.
• Each of the sets has 3 connector elements, respectively male 3 (with a male contact element) for the upper clearance or plug, and females 5 (with a female contact element) for the lower clearance or base.
• the connector elements 3, 5 each comprise an insulating body 13 and a contact element 7 or 9 fixed in the body ( Figures 2 and 3).
• the insulating bodies 13 are identical with the resulting manufacturing advantage.
• the male contact elements 7 are identical, as are the female contact elements 9.
• the insulating bodies 13 are mounted opposite from a clearance to the other. They are essentially rectangular parallelepipedal in shape and each have a through central bore 15 housing the contact element 7 or 9, and two parallel lateral drilling holes 17 arranged in the same plane perpendicular to the bore 15 and close to the base.
• the contact elements 7, 9 are cylindrical, substantially the same diameter as the bore 15, each being fixed axially therein.
• the drilling holes 17 each receive a threaded rod 19 (threaded into the body), and the connector elements 3, 5 of each of the sets are thus connected in position adjacent to each other, by means of two threaded rods 19, being mounted tight to one another by means of two end tabs 21 on which nuts 23 are applied tightly to the ends of the threaded rods 19.
• Insulating flanges 25 are interposed between the connector elements 3, 5. These flanges 25 increase the current creepage path (to be used for power connectors) and protect against any risk of electric arc between the contact elements 7 or 9 in charge.
• the plug-in connector has a median longitudinal plane of symmetry (with the exception of the nesting elements described below) containing in particular the axes of the contact elements 7, 9 and centering guides 27, and the insulating bodies 13 are mounted opposite axially to each other as mentioned above. These bodies include an external threaded shoulder 31 receiving the cable conductor clamp (not shown) connected to the contact element, and at the opposite end an enlarged annular recess 33 capable of receiving a sealing ring as required. 35 of the contact (see Figures 2,3). This ring 35 can be fixed on the male connector element 3, being held by a latching washer 37 engaged at the base of the male contact element 7.

The opposite game naturally has the same configuration.
• the connector elements are arranged in three rows 56 of two connector elements connected to a rigid rectangular frame 57. Each of the rows 56 results from a linear assembly of two connector elements 3 'or 5' threaded on two threaded rods 19 ' fixed to said framework 57.
