- Patents FR 2,686,459, FR 2,701,150 and FR 2,710,788 relate to methods of connecting a cable to a contact and to a crimping tool of such a contact suitable for aluminum cables.
- they require the use of contacts having a partially frustoconical outer surface and are therefore not suitable for contacts of cylindrical outer shape at least in the parts to be crimped.
- the patents FR1.240.942 and US2.985.047 relate to a tool allowing, in one embodiment, crimping a contact both on the conductive core of the cable and on a non-stripped portion of its insulating sheath.
- This tool comprises articulated jaw blades forming two stages operated simultaneously, one ensuring crimping of the contact on the conductive core and the other ensuring crimping of the contact on the insulating sheath.
- the part of the contact crimped on the insulating sheath has a section whose perimeter comprises three flat faces arranged substantially in a triangle, interconnected by concave portions.
- this section is not suitable for connector contacts used in particular in aeronautics because the tools for inserting and extracting said contacts in these connectors require that the section of the contacts crimped on the insulating sheath be substantially elliptical and preferably circular .
- the best airtightness of the crimping of the contact on the insulating sheath is still obtained with a section of the contacts crimped on the substantially elliptical and preferably circular insulating sheath.
- crimping said contact on the conductive core should preferably have a section with concave portions distributed over its perimeter in order to obtain good mechanical tensile strength characteristics and good electrical connection characteristics.
- US Patent 3,713,322 relates to a tool for crimping a contact in a substantially circular section.
- this tool does not allows only one crimping at a time and is therefore not suitable for crimping a connector contact on an aluminum cable.
- Patent applications US2004 / 072378 and WO2004 / 021523 describe a tool having two crimping stages and for crimping a contact both on the conductive core of the cable and on the insulating sheath of this cable, substantially simultaneously.
- a tool requires significant effort on the clamping handles. These efforts are all the more important as the diameter of the cable is high. They are particularly troublesome when returning the tool to the rest position at the end of crimping. In addition, such forces can cause rapid wear of some parts of the tool.
- a crimping tool of a contact on the end of a cable said cable end having a stripped portion where a conductive core of the cable is stripped and an isolated part. wherein said conductive core is covered by an insulating sheath, said contact comprising a hole coaxial with the longitudinal axis of said contact adapted to receive both said stripped portion and said insulated portion of the cable end, said crimping tool comprising:
- said first stage and second stage comprise crimping elements able to be displaced relative to the crimp contact during crimping;
- At least one of said first stage and second stage comprises a cam cooperating with the crimping elements of the stage considered to move them so as to crimp the contact during crimping; this tool being furthermore remarkable in that at least one rotary element is disposed between at least one of said crimping elements and said cam, this rotary element being able to occupy at least two positions relative to the crimping element considered such that when this rotating element is in contact with both this crimping element and with said cam, the distance between on the one hand said cam and on the other hand an end of this crimping element able to touch said contact to crimp it is different in said at least two positions.
- this tool is designed so that during a displacement of the cam relative to the crimping elements, in a first direction corresponding to a crimping, said rotary element occupies a first position with respect to said crimping element, wherein said distance is maximum, and upon displacement of the cam relative to the crimping elements, in a second direction, inverse of the first direction, said rotary member occupies a second position with respect to said crimping member, wherein said distance is minimal.
- said second stage comprises means capable of crimping a substantially elliptical section.

- said cam is rotatably mounted around a jaw support, said cam having a track which cooperates with ends of the jaws to move them radially. to the crimp contact, during crimping, these jaws being slidably mounted in grooves of the jaw support.
- This tool thus serves to crimp the contact simultaneously on the conductive core of the cable and on the insulating sheath, the crimping on the insulating sheath having a substantially elliptical or circular section, which allows both a good airtightness and thus a protection against the oxidation of the crimping on the conductive core, as well as a compatibility with the tools of insertion and / or extraction of the contact in the connectors used in particular in aeronautics.
- At least one rotary element is disposed between at least one jaw end and said track, this rotating element being able to occupy at least two positions with respect to the jaw end considered, such that when this rotary element is in contact both with this end of jaws and with said track, the distance between on the one hand said track and on the other hand another end of the jaw able to touch said contact to crimp is different in said at least two positions.
- the crimping tool is designed so that during a rotation of the cam around the jaw support in a first direction corresponding to a crimping, said rotary member occupies a first position relative to at said jaw end, wherein said distance is maximum, and upon a rotation of the cam about the jaw support in a second direction, inverse of the first direction, said rotary member occupies a second position with respect to said end of jaws, wherein said distance is minimal.
- said rotary element is a substantially spherical ball.
- said rotary element is a substantially cylindrical roller.
- said roller is mounted integral with an axis of rotation coaxial with said roller and whose ends can slide in slides secured to said jaw end.
- said track of the cam comprises a notch at each position of said track facing each jaw which is associated with a rotary member when said cam is at the end of stroke relative to the jaw support, during crimping. These notches facilitate the passage of said rotary members from said first position to said second position at the end of crimping, in order to reduce friction on the track of the cam when the crimping tool returns to its rest position.
- said track has a shape adapted to allow centrifugal radial movement of the jaws at the end of crimping so as to release these jaws of said contact.
- the jaw supports are integral with a first handle and the cams are integral with a second handle, said first handle and second handle being common to the first stage and the second stage.

- the jaws of the first group have ends adapted to touch the crimp contact whose shape substantially corresponds to a plane whose orientation is substantially tangent to the contact during crimping;
- the jaws of the second group have ends capable of touching the crimp contact whose concave shape corresponds substantially to a cylinder arc smaller than a half-cylinder;
- the two jaws of the first group are arranged diametrically opposite on either side of a hole of the jaw support adapted to receive the crimp contact;
- the two jaws of the second group are arranged diametrically opposite on either side of said hole of the jaw support adapted to receive the crimp contact; the jaws of the second group are oriented at an angle substantially equal to 90 degrees with respect to the jaws of the first group.

- said first stage comprises means capable of producing a crimping whose section has concave parts on its perimeter. This makes it possible to obtain a crimping of the contact on the conductive core of the cable having satisfactory characteristics of mechanical tensile strength as well as of electrical connection between the conductive core of the cable and this contact.
- the first stage comprises four identical jaws such as:
- Two jaws other than neighboring jaws are arranged diametrically opposite on either side of a hole of the jaw support adapted to receive the crimp contact;
- the ends of said jaws able to touch the crimp contact have a convex shape capable of imparting concave deformations in this contact during crimping.
- This embodiment of the first stage therefore serves to crimp the contact on the conductive core of the cable by obtaining the required characteristics of electrical connection and mechanical tensile strength.
- the invention is however not limited to first and second crimping stages comprising jaws moving radially to the crimp contact.
- the invention also relates to a method of crimping a contact on the end of a cable, said cable end having a stripped portion where a conductive core of the cable is stripped and an insulated portion where the conductive core is covered by a insulating sheath, said contact comprising a hole coaxial with the longitudinal axis of said contact adapted to receive both said stripped portion and said insulated portion of the cable end, wherein:

- the jaw support 10 of the first stage is shown in more detail in Figure 2. It has grooves 14 radial to its axis and therefore also radial to the axis of the crimp contact when it is inserted into the hole 6 of the crimping tool.
- said jaw support has four grooves 14; these are arranged two by two diametrically opposite with respect to the axis of the jaw support and two adjacent grooves are offset from each other by an angle substantially equal to 90 degrees.
- Each of said grooves receives a jaw 18 able to slide in this groove. For clarity of the figure, only one of said jaws is shown.
- the jaw support 10 of the first stage, equipped with four jaws 18, is shown surrounded by the cam 12 in the rest position.
- the track 16 of this cam is shaped so as to cooperate with ends of the jaws 18 to allow a displacement of said jaws radially to the axis of rotation of the jaw support 10, towards this axis of rotation, when said cam rotates around of the jaw support, in the direction of arrow F, during crimping.

- the track 16 has notches 32 at positions of said track facing each of the jaws 18 when the cam 12 is at the end of the stroke relative to the jaw support 10. during crimping.
- Each of said slots 32 may for example correspond to a groove, substantially perpendicular to the plane of Figure 9a, formed in said track 16; without departing from the scope of the invention, it may also correspond to a blind hole in the track 16. This is very advantageous because, at the end of crimping, the rotating element 30 is no longer in contact with the track 16 because of the presence of said notch.
- the rotary member 30 is more subject to frictional forces against this track 16 and it can easily move from said first position (corresponding to crimping) to said second position (corresponding to the return of the crimping tool in the rest position).
- the depth of this notch 32 in the track 16 is preferably determined taking into account the elastic deformation of the crimp contact: this depth is at least equal to the displacement of the jaw 18 under the effect of the elastic deformation of said contact, in the end crimping, when the jaw is no longer subjected to the forces applied by means of said rotary member 30. This ensures that the rotary member 30 is released from the friction forces on the track 16.
- the depth of said notch 32 is smaller than the difference in distance d1, considered in projection on a line dr radial to the axis of the jaw support 10 and passing through the jaw 18, between the positions G1 and G2 occupied respectively by the center of gravity of the rotating element 30 on the one hand in said first position and secondly in said second position, shown in Figure 9b.
- d1 considered in projection on a line dr radial to the axis of the jaw support 10 and passing through the jaw 18, between the positions G1 and G2 occupied respectively by the center of gravity of the rotating element 30 on the one hand in said first position and secondly in said second position, shown in Figure 9b.
- said notch 32 results from the fact that preferably the length it occupies on the track 16 is at most substantially equal to the width Lm of the jaw 18, said notch being, moreover, located at a position on the track 16 corresponding to the end of crimping.
- the track length 16 useful for the actual crimping is not significantly reduced due to the presence of said notch. Therefore, it is possible to conform said track 16 so as to distribute the crimping forces of the contact throughout the crimping movement, while benefiting from the aforementioned advantages of said notch 32 and said rotary member 30 as to the reduction of efforts friction, especially when returning the crimping tool 1 in the rest position.
- said track 16 comprises parts 17 allowing centrifugal radial displacement of the jaws in order to release the jaws of the contact at the end of crimping.
- Such a portion 17 is provided at positions of said track facing each of the jaws when said cam is at the end of stroke relative to the jaw support, during crimping.
- the second stage comprises two groups of two jaws.
- the jaws 28a of the first group have ends capable of touching the crimp contact whose shape substantially corresponds to a plane whose orientation is substantially tangent to this contact during crimping.
- the jaws 28b of the second group have ends capable of touching the crimp contact whose concave shape corresponds substantially to a cylinder arc smaller than a half-cylinder.

- the jaws 28b of the second group are oriented at an angle substantially equal to 90 degrees relative to the jaws 28a of the first group.
- the lengths of the jaws 28a of the first group on the one hand and the jaws 28b of the second group on the other hand, as well as the shape of the track 26 are advantageously provided so that, during crimping:
- the first stage for its part, preferably comprises four identical jaws able to perform a crimping of the contact whose section comprises concave parts on its perimeter.
- Each of said jaws can in particular be:
- a ridge is adapted to touch said crimp contact in a single segment 33 of said ridge to form a concave part;
- one edge is adapted to touch said crimp contact two disjoint segments 35a and 35b of said edge to form two concave parts, for example according to MIL-C-22520.
- the four jaws of the first stage are arranged so that two neighboring jaws are offset from each other by an angle substantially equal to 90 degrees and that two jaws other than neighboring jaws are diametrically opposed from each other. else of the hole 6 of the jaw support 10 adapted to receive the crimp contact.
- the crimping tool 1 makes it possible to simultaneously actuate the first stage and the second stage by means of the first handle 4 and the second handle 2. In this way, it enables the crimping to be performed substantially simultaneously. contact 34 on the electrical core of the cable by means of the first stage and the crimping of this contact on an insulating sheath of the cable by means of the second stage.
- the crimping tool 1 since in the aforementioned preferred embodiments the first stage makes it possible to perform a crimping such that the section of the contact 34 has concave parts on its perimeter and that the second stage makes it possible to perform a crimping such that the section of the contact is substantially while reducing the efforts during the return of the crimping tool in the rest position, the crimping tool 1 according to the invention therefore advantageously solve the problems of the prior art.
