    1 CONNECTOR FOR CONNECTING TWO ELECTRIC CABLES TOGETHER 5 The invention relates to connectors for connecting two electric cables together. Such a connector for connecting two electric cables together, typically cables formed by a conductive core and an insulating sheath, is already known, particularly from French patent application 2 762 449, such a 10 connector providing both an electrical connection and a mechanical connection of the two cables. The connector described by this document comprises: two jaws and a screw/nut pair to bring said jaws together, each of said jaws comprising a body made from a rigid insulating material and a conductive contact member 15 having two active portions, each configured to protrude from a receiving surface of the jaw respectively to enter the conductive core of one cable and the conductive core of the other cable, the receiving surface of each jaw facing the receiving surface of the other jaw, with each active portion of the contact member of one jaw in line with an active portion of the contact member of the 20 other jaw, said connector being configured to permit a cable placement position in which the cables are placed between the receiving surfaces of the jaws with each active portion of a contact member in line with a cable, to permit an operational position in which the cables are sandwiched between the jaws with each active portion having entered a conductive core of a respective cable, and 25 to move from the cable placement position to the operational position by the jaws being brought together with the screw/nut pair. Generally, such connectors are used in low-voltage electricity distribution systems (i.e. between 110 and 1,000 volts RMS) and are entirely satisfactory. 30 The invention aims to make possible the use of such connectors in medium- and high-voltage electricity distribution networks (i.e. between 1,000 and 110,000 volts RMS).
    2 To this end, the invention proposes a connector for connecting two electric cables together, comprising two jaws and at least one tightening member for bringing said jaws together, each of said jaws comprising a body made from a rigid insulating material and a conductive contact member having 5 two active portions each configured to protrude from a receiving surface of said jaw respectively to enter the conductive core of one cable and the conductive core of the other cable, the receiving surface of each jaw facing the receiving surface of the other jaw, with each active portion of the contact member of one jaw in line with an active portion of the contact member of the other jaw, said 10 connector being configured to take a cable placement position in which the cables are placed between the receiving surfaces of the jaws, with each active portion of a contact member in line with a cable, to take an operational position in which the cables are sandwiched between the jaws with each active portion of each contact member having entered a conductive core of a respective 15 cable, and to move from the cable placement position to the operational position by the jaws being brought together by the tightening member; said connector comprises a solid metal element surrounded by said body made from a rigid insulating material; characterized in that at least one said jaw comprises, on said receiving surface, between said solid metal element and one said active 20 portion, a surface element that is more conductive than said body made from a rigid insulating material, said surface element being configured to carry, in the event of the occurrence of a potential difference between said solid metal element and said active portion, a potential-equalization current between said solid metal element and said active portion. 25 In the aforementioned connector of the prior art, the solid metal elements such as the screw/nut pair, separated from the contact members by the insulating material of the body of the jaws, have floating potential; consequently, in the presence of the higher voltages in medium- and high voltage distribution networks, there can be a very significant potential difference 30 between the conductive core of the cables connected by the connector (and therefore the contact member connecting them) and the solid metal parts. If the surfaces of the connector are contaminated, for example with dust or water, an 3 electric arc may occur on the surface of the insulating materials, known as tracking, capable of damaging the insulating materials. In the connector according to the invention, the surface element procures on the surface of the insulating materials the path of least resistance, 5 and the potential-equalization current is therefore carried by the surface element. Depending on the potential difference and the resistance value of the path of least resistance procured by the surface element, the potential equalization current is carried more or less smoothly or more or less suddenly. 10 Even in the latter case (sudden flow, i.e. a discharge), the fact that the tracking takes place on the added surface element rather than on the surface of the insulating material of the jaw, for example, makes it possible to avoid the damage caused by such tracking when it takes place on the surface. The insulating portions of the connector according to the invention 15 are thus protected from damage by tracking. According to features that are preferred for reasons of simplicity, convenience and/or performance of the connector according to the invention: - said solid metal element forms part of a screw comprised by said tightening member; 20 - said surface element is a jacket made from a flexible sheet material; - said jacket comprises a plastic sheet and a conductive additive; - said jaw, which comprises a surface element between said solid metal element and one said active portion, comprises a seal made from a 25 flexible insulating material around said active portion, said seal being covered by a cover comprised by said surface element; - said cover comprises at least one slot through which a tooth of said active portion passes; - said flexible plastic seal comprises a curved wall that is concave 30 on the outer side, connected to a skirt surrounding it; and said cover has a curved wall covering the curved wall of the flexible seal and a skirt covering the skirt of said seal; 4 - said cover comprises a flanged edge connected to said skirt on a side away from said curved wall; - said surface element comprises a connecting flange between said cover and said solid metal element; 5 - said flange comprises at least one ring surrounding a shank comprised by said solid metal element; - said ring surrounds a tube in which is arranged said shank, with at least one tab engaged in an opening of said tube; - said surface element comprises two said rings and a connecting 10 portion between said rings and said cover; - said jaw comprising said surface element comprises three said contact members and two said tightening members each comprising a metal screw, with said cover arranged on the seal surrounding an active portion arranged between two other active portions and each said ring surrounding the 15 shank of a respective one of said screws; and/or - one of said jaws has a side wall closing said connector, in the operational position, on the side on which said cover is located. The disclosure of the invention will now continue with a detailed description of an embodiment, given below as a non-limitative illustration, with 20 reference to the attached drawings, in which: - Figure 1 is a highly diagrammatical plan view of a connector according to the invention, in the operational position in which it connects two electric cables together; - Figure 2 is a cross-sectional elevation view along the line marked 25 Il-1l in Figure 3, showing the connector according to the invention in the cable placement position, with one of the cables shown; - Figure 3 is a cross-sectional view along the line marked 1ll-Ill in Figure 2; - Figures 4 to 6 are front, plan and side elevation views respectively 30 of the jaw shown at the bottom of Figure 2, together with metal screws comprised by the connector to bring the jaws together; and 5 - Figure 7 is a perspective view of the jacket comprised by the connector according to the invention to carry, in the event of the occurrence of a potential difference between the metal screws and the contact member shown at the bottom of Figure 2, a potential-equalization current between said screws 5 and said contact member. The connector 10 shown in Figures 1 and 2 is intended to provide an electrical connection between two electric cables 11 and 12 (Figure 1). As shown in Figure 2, the cable 11 comprises a conductive core 13 covered by an insulating sheath 14. Similarly, the electric cable 12 comprises a. 10 conductive core covered by an insulating sheath. In the operational position shown in Figure 1, the connector 10 provides both an electrical connection and a mechanical connection between the cables 11 and 12. The connector 10 comprises a jaw 15 (Figure 2), a jaw 16 and two 15 tightening members 17 to bring the jaws 15 and 16 together. Each of the jaws 15 and 16 has a receiving surface 20. The receiving surface 20 of the jaw 15 is facing the receiving surface 20 of the jaw 16. The connector 10 is configured to receive the cables to be 20 connected, such as 11 and 12, between the receiving surface 20 of the jaw 15 and the receiving surface 20 of the jaw 16. In the cable placement position (Figure 2), the receiving surfaces 20 are sufficiently far apart for the cables to be placed between them. Active portions 21 of contact members 22 protrude from each 25 receiving surface 20. Each contact member 22 is made from a U-shaped rigid conductive metal plate with a central arm and two distal arms. Each distal arm ends in an active portion 21, here comprising three pointed teeth arranged side by side. 30 Each active portion 21 is configured to puncture the insulating sheath such as 14 and enter the conductive core such as 13 of a cable to be connected 6 such as the cable 11 or the cable 12 when the jaws 15 and 16 are brought together with the tightening members 17. On either side of the tightening members 17, the active portions 21 of the contact members 22 are aligned in an axial direction, i.e. in the direction in 5 which the cables such as 11 and 12 are intended to be arranged between the jaws 15 and 16, with each active portion 21 of the jaw 15 in line with an active portion 21 of the jaw 16. Here, the connector 10 comprises three contact members 22 in each of the jaws 15 and 16. Each of the tightening members 17 comprises a metal screw 25 10 comprising a head 26 and a shank 27. The head 26 of each screw 25 is arranged facing an outer surface 28 of the jaw 15, which is located on the side of the jaw 15 opposite the receiving surface 20. The jaw 15 has a passage for each screw 25 made in the outer 15 surface 28 and the receiving surface 20. The shank 27 is engaged freely in this passage. The jaw 16 has a recess for each screw 25, in which is immobilized a nut in which the shank 27 is engaged. The nut has an internal thread and the shank 27 has an external thread with a corresponding configuration, so that 20 when the screw 25 is turned in the screwing direction, the shank 27 enters the recess; when the screw 25 is rotated in the unscrewing direction, the shank 27 emerges. A metal washer 29 is placed between the head 26 of each screw 25 and the outer surface 28 of the jaw 15. 25 Each head 25 is covered by a plastic cap 30 having at its distal end a head 31 with a prismatic cross-section, here hexagonal, connected to the rest of the cap 30 by a frangible portion 32 configured to break under the effect of a predetermined torque. To connect the electric cables such as 11 and 12 together, the 30 connector 10 is placed in the cable placement position shown in Figure 2, in which the receiving surfaces 20 of the jaws 15 and 16 are sufficiently far apart 7 to enable the arrangement of a cable such as 11 on the side shown on the left in Figures 1 to 5 and a cable such as 12 on the side shown on the right. A tool such as a spanner is engaged on the head 31 to turn the screw 25 in the screwing direction, the head 26 comes into contact with the 5 washer 29, which in turn comes into contact with the outer surface 28 of the jaw 15, the jaws 15 and 16 come together, the active portions 21 puncture the insulating sheath of the cables such as 11 and 12 and then enter the conductive core of said cables, and when they have entered far enough, the frangible portion 32 of the head 31 of the cap 30 breaks, said frangible portion 32 being 10 configured accordingly. In the example shown, the connector 10 is intended to connect a branch cable such as 11 to a main cable such as 12, with the main cable having a larger cross-section than the branch cable. The active portions 21 shown on the left in Figures 2 to 5 are for the branch cable such as 11 and the active 15 portions 21 shown on the right are for the main cable such as 12. Due to the difference in cross-section between the cables such as 11 and 12, the active portions 21 shown on the left in Figures 2 to 5 protrude more than the active portions 21 shown on the right. In the configuration shown in Figure 1, the branch cable 11 extends 20 on just one side of the connector 10. Consequently, to protect the end of the cable 11, the connector comprises a watertight plug 33. Each active portion 21 emerges from a watertight seal 35. The seal 35, shown on the right in the middle of Figures 3 and 5, will now be described in more detail. 25 The seal 35 has a curved wall 36 that is concave on the outer side. The active portion 21 emerges through the curved wall 36. The curved wall 36 is connected to a skirt 37 that surrounds it. Each of the jaws 15 and 16 comprises three contact members 22 arranged parallel to each other in a direction transverse to the intended 30 direction of the cables to be connected such as the cables 11 and 12. For the jaw 16, on the side shown on the right in Figures 2 to 5, the seal 35 shown at the top of Figure 3 and the seal 35 shown at the bottom of 8 Figure 3 are identical to the seal 35 shown in the middle, which has just been described. For the jaw 15, each of the seals 35 located on the side shown on the right is identical to the seal 35 that has just been described. 5 On the side shown on the left in Figures 2 to 5, the seals 35 are similar, with a curved wall 36 and a skirt 37 that protrude more, in the same way as the active portions 21 shown on the left. For the seal 35 shown in the middle on the left in Figure 3, the curved wall 36 and the skirt 37 are thinner because said seal 35 is covered, as 10 explained in more detail below, by a cover 51 of the jacket 50 shown in isolation in Figure 7. Each seal 35 forms part of an envelope 38 receiving one of the contact members 22. In each envelope 38, the seals 35 that cover the two active portions 15 21 of a contact member 22 are connected by a U-shaped saddle 39, the central wall 40 of which extends between the skirts 37 of the two seals 35 comprising the envelope 38. In each envelope 38, the skirt 37 of each seal 35 is connected, on the side away from the curved wall 36, with the exception of the section 20 connected to the central wall 40 of the saddle 39, to a flanged edge 41. At each end, the side walls of the saddle 39 are connected to a flanged edge 41. Each contact member 22 is thus covered by an envelope 38 over its entire surface, with the exception of the active portions 21 and the side away from the active portions 21. 25 Here, the three envelopes 38 are connected to each other by spacers 42, each extending between two adjacent seals 35. Here, the spacers 42 are each formed by a flat wall. The assembly formed by the envelopes 38 linked by the spacers 42 forms a packing seal 43. 30 In each of the jaws 15 and 16, the assembly formed by the packing seal 43 and the three contact members 22, each arranged in one of the 9 envelopes 38 of the packing seal 43 is received in a body 44 made from a rigid insulating plastic material. The packing seal 43 is made from a flexible insulating plastic material. 5 Each assembly formed by a contact member 22 and an envelope 38 surrounding said contact member is received in an indentation in the body 44 so that only the seals 35 and the active portions 21 protrude from the body 44. When the jaws 15 and 16 are brought together to puncture the insulating sheath such as 14 and enter the conductive core such as 13, the 10 seals 35 deform due to the flexibility thereof and the rigidity of the body 44. Thus, the seals 35 follow the shape of the sheath such as 14 and provide a watertight seal. So that the cable such as 11 is positioned correctly vis-A-vis the corresponding active portions 21, the seals 35 shown in the top left and bottom 15 left of Figures 3 and 5 comprise guide lugs 45. The body 20 of the jaw 16 comprises two tubes 46 each defining an inner space continuing on from one of the recesses receiving the shank 27 of one of the screws 25. The tubes 46 (and therefore the shanks 27 and the corresponding 20 recesses in the body 44 of the jaw 16) are centred on an axial mid-plane (parallel to the intended direction of the cables such as 11 and 12) and arranged on either side of a transverse mid-plane. In the axial direction, each tube 46 is arranged between an end contact member 22 (contact member shown top and bottom in Figures 3 to 5) 25 and the middle contact member 22. Each of the tubes 46 has two narrow openings 47, each extending over the entire length of the tube 46 along the axial mid-plane. Each portion of tube 46 extending between two openings 47 surrounds the shank 27 of a screw 25 on the side where a cable such as 11 or 30 a cable such as 12 is placed. Thus, the tubes 46 prevent a cable such as 11 or 12 from coming into contact with the shank 27 of a screw 25, the thread of which might damage the insulating sheath such as 14.
    10 According to the invention, the connector 10 comprises a jacket 50 shown in isolation in Figure 7. The jacket 50 comprises a cover 51 covering the seal 35 shown on the left in the middle in Figures 3 to 5 and a flange 52 to connect the cover 51 to 5 the shank 27 of the metal screws 25. The jacket 50 is made from a relatively thin flexible sheet material, more conductive than the body 44 of the jaw 16, so that it can carry, in the event of the occurrence of a potential difference between one of the metal shanks 27 and the active portion 21, shown on the left in the middle in Figures 3 10 to 5, a potential-equalization current between said metal shank 27 and said active portion 21. The assembly formed by the seal 35 shown on the left in the middle in Figures 3 and 5 and the cover 51 covering it has an outer configuration similar to the other seals 35. To this end, the seal 35 shown on the left in the middle in Figures 3 15 and 5 has an outer indentation having the same configuration as the cover 51 and a depth corresponding to the thickness of the material from which the cover 51 is made (see in particular Figure 2). The cover 51 has a curved wall 53 that is concave on the outer side. For each tooth of the active portion 21, the curved wall 53 has a slot 54. 20 The curved wall 53 is connected to a skirt 55 that surrounds it. Each side section of the skirt 55, i.e. each section oriented transverse to the axial direction of the connector 10, is connected to a flanged edge 56 on the side away from the curved wall 53 (Figure 7). In the connector 10, each flanged edge 56 is engaged between the 25 body 44 of the jaw 16 and the seal 35 covered by the cover 51. This favours the securing of the jacket 50 vis-b-vis the rest of the jaw 16. The flange 52 comprises two rings 57 and a connecting portion 58 between the rings 57 and the cover 51. Two diametrically opposite tabs 59 protrude from the inner 30 circumference of each ring 57. Each ring 57 surrounds a tube 46 and each tab 59 is engaged in a respective opening 47. Because the jacket 50, and consequently the cover 51, 11 is made from a relatively flexible sheet material, the cover 51 deforms like the seal 35 that it covers when the active portion 21 enters a cable such as 11. The cover 51 therefore actively contributes, with the seal 35 that it covers, to procuring a watertight seal around the active portion 21, the teeth of 5 which pass through the slots 54. Because the material located on the periphery on the slots 54 is in contact with or immediately adjacent to the active portion 21, the tabs 59 are in contact with or immediately adjacent to the metal shanks 27 of the screws 25 and the material from which the jacket 50 is made is more conductive than the 10 material from which the body 44 of the jaw 16 is made, in the event of the occurrence of a potential difference between a shank 27 (and more generally a screw 25) and the active portion 21, the teeth of which pass through the slots 54 (and more generally the conductive core of the cables such as 11 and 12), the jacket 50 will provide the path of least resistance and carry a potential 15 equalization current between the metal shank 27 and the active portion 21. Depending on the potential difference and the resistance value of the path of least resistance procured by the jacket 50, the potential-equalization current is carried more or less smoothly or more or less suddenly. In the latter case (sudden flow, i.e. a discharge), the fact that the 20 tracking takes place on the jacket 50 rather than on the surface of the packing seal 43 and/or the insulating body 44 makes it possible to avoid the damage caused by such tracking when it takes place on the surface. It will be noted that in the operational position of the connector 10, no part of the jacket 50 is directly accessible from the outside, since: 25 - the cover 51 is separated from the outside by a side wall 60 comprised by the jaw 15 on the side shown on the left in Figures 1 to 5; - the cover 51 is separated from the outside by the end seals 35 between which it is located, i.e. the seals 35 shown on the top left and bottom left in Figures 3 and 5; and 30 - the flange 52 is at a distance from the transverse surfaces of the connector 10, i.e. the surfaces oriented parallel to the contact members 22, in a location between the cables such as 11 and 12.
    12 In the example shown, the jacket 50 is made from a flexible plastic sheet coated in carbon black so that it is conductive. As a variant, the jacket 50 is made from a plastic material moulded with carbon particles. As a further variant: 5 - the carbon black or carbon particles are replaced by another conductive additive, for example carbon fibres or another form of carbon and/or fibres of another conductive material, for example copper; and - the jacket 50 is made from a sheet of metal such as copper or aluminium. 10 In a variant (not shown), the flange of the jacket such as 50 provides a link with solid metal elements other than the screw 25, for example a nut of the tightening members. In variants (not shown): - the jacket such as 50 comprised by the jaw such as 16 is 15 replaced by another surface element that is more conductive than the insulating body 44 and packing seal 43, for example a wire or ribbon or even a coating or plating made from a conductive material; - the active portions 21 do not emerge from the seals such as 35 in the cable placement position, while each remaining configured to protrude 20 from the receiving surface such as 20 during the move from the cable placement position to the operational position under the effect of the sandwiching of the cables; and/or the portion of the surface element such as the cover 51 does not have any slots such as 54, the teeth of the active portion such as 21 puncturing the cover during the move from the cable placement 25 position to the operational position; - the tightening member such as 17 is different from a screw/nut pair, for example a rivet; - the connector is intended to connect a branch cable having the same cross-section as the main cable, or even a branch cable having a larger 30 cross-section than the main cable, or to connect two main cables; - the number of conductive members such as 22 is different from 3, for example 2 or 4; 13 - the number of tightening members such as 17 is different from 2, for example I or 3; and/or - the number of teeth of the active portions such as 21 is different from 3, for example 2 or more than 3. 5 A number of other variants are possible depending on the circumstances, and it must be pointed out in this regard that the invention is not limited to the examples described and shown.
