  • the present invention relates to a connection element between, on the one hand, a coaxial cable comprising a central core and an outer braid, and, on the other hand, a first and a second contact pin. It also relates to a set of such connection elements.
  • the invention advantageously applies to the general technical field of electrical connections.
  • connection between a coaxial cable and contact pins constituting, for example, the rear parts of a connector contact through a card
  • the connection between the central core of the cable and one of the contact pins can be carried out quite easily by soldering or crimping
  • the connection of the ground braid to the second contact pin is much less easy to carry out since it is necessary, not only to strip the cable, but also to untwist the strands of the braid, then to bring them together in a single conductor which must then be welded on said second pin, or to come solder on the braid a short length of an auxiliary conductor.
  • the connection thus obtained does not lend itself easily to frequent disassembly and reassembly.
  • connection element in accordance with the preamble, which would be easy to use, quick and safe and also removable and reassemblable as many times as necessary and without wear. excessive.
  • said connecting element consists of a core ferrule and a mass ferrule, each made of a conductive material with shape memory, and shaped so as to be able to adapt closely, in a first state of shape memory, respectively to said central core and to said outer braid and to be able to ensure the release and / or the engagement of said core ferrules and mass in a second shape memory state, the core and mass ferrules being respectively connected to a first and a second sockets intended to ensure the electrical connection and the mechanical cohesion respectively with said first and said second contact pins .
  • the connecting element, object of the invention comprises two parts, a core ferrule and a mass ferrule which can be easily connected, on the one hand, to the central core and, on the other hand , to the outer braid after the cable has been stripped.
  • the ferrules below the transition temperature of the conductive material with shape memory, that is to say in the martensitic phase, to engage the ferrules respectively on the core and on the braid, then, by increasing the temperature, passing the material into its austenitic phase where, by effect of shape memory, the ferrules of core and braid resume their first state of shape, that is to say say the one that provides the best electrical and mechanical contact.
  • the ferrules are again brought to a temperature below the transition temperature, in the martensitic phase, then disconnected from the central core and from the outer braid.
  • the transition temperature in the martensitic phase, then disconnected from the central core and from the outer braid.
  • there is therefore a coaxial cable which has been provided in a very simple, rapid and effortless manner with ferrules which can be assembled and dismantled at will, terminated by sockets easily. connectable to contact pins.
  • connection element object of the invention, it is provided that at least one of said sockets is made of a conductive material with shape memory, and shaped so as to be able to adapt closely , in a first state of shape memory, to one of said contact pins and to be able to ensure the release and / or the engagement of said socket in a second state of shape memory.
  • an increase in temperature is carried out which brings the various components of the connection element endowed with shape memory into their first shape memory state corresponding to the optimum contact.
  • the shape memory materials constituting the connection element according to the invention were different, it would be advisable that at operating temperature, for example ambient temperature, all the materials be in the austenitic phase in order to all shape memory components are in their first shape memory state.
  • the martensitic transition temperatures can be different so as to be able, if necessary, to disengage the sockets from the contact pins without at the same time disengaging the core and braid ferrules. In this case, the martensitic transition temperature of the ferrules should be lower than that of the sleeves.
  • the transition from the first shape memory state to the second shape memory state is effected in a reversible manner simply by crossing the transition temperature of said shape memory material, which it be the material constituting the ferrules and, where appropriate, the sockets.
  • connection elements according to the invention is remarkable in that the first and second sockets are held in the same insulating housing. This arrangement makes it possible to provide the various connection elements with the solidarity necessary for the easy use of said assembly.
  • Figure 1 is a perspective view of a connecting element according to the invention.
  • Figure 2 is a perspective view of a split socket used in the invention.
  • Figure 3 is a perspective view of a clip socket used in the invention.
  • Figure 4 is a front view of a set of connecting elements according to the invention, held in an insulating housing.
  • Figure 1 shows in perspective a connecting element between, on the one hand, a coaxial cable 10 and, on the other hand, a first 21 and a second 22 contact pins.
  • the coaxial cable 10 comprises a central core 11 and an outer braid 12.
  • the core 11 and the braid 12 are intended respectively to be connected to the contact pins 21 and 22.
  • These contact pins can be rear parts of a contact passing through a card 50, or even through pins of the pressfit or soldering type.
  • the connecting element of Figure 1 consists of a ferrule 31 of core and a ferrule 32 of mass, each made of a conductive material with shape memory, and shaped so as to be able to adapt closely, in a first state of shape memory, respectively to said central core 11 and to said outer braid 12 and to be able to ensure the release and / or the engagement of said core and mass ferrules in a second state of shape memory form.
  • the ferrules 31, 32 will, in their first state of shape memory, in the austenitic phase, at the operating temperature of the connection element, that is to say for example at the usual ambient temperature .
  • the transition to the second shape memory state in which the ferrules are engaged on or disengaged from the core 11 and the braid 12 of the coaxial cable 10, is then obtained by decreasing the temperature below the transition temperature shape memory material, in martensitic phase.
  • the release of the ferrule 31 of the core and of the ferrule 32 of mass in the martensitic state can be carried out with a weak force exerted either manually, or using an elastic return member whose action is canceled and overcome by the shape memory effect when returning to the austenitic phase.
  • said release can also be carried out at zero force when the transition from the first to the second shape memory state is effected in a reversible manner simply by crossing the transition temperature of the conductive shape memory material.
  • This mode of operation requires subjecting the ferrets of soul and mass to an education process described in European patent application No. 86 400 560.8, and the general principles of which are given in European patent application No. 85 400 523.8.
  • the ferrules 31, 32 of core and of mass are connected respectively to a first 41 and a second 42 sockets intended to ensure electrical connection and mechanical cohesion respectively with said first 21 and said second 22 contact pins.
  • the sleeve 41 is directly connected to the ferrule 31 of the core, while the sleeve 42 is connected to the ferrule 32 of mass by means of a connecting lug 52.
  • the sockets 41 and 42 are sockets of the "split socket" type, shown in FIG. 2, and comprising a slot extending only partially over the length of said sockets.
  • the material constituting the split bushings may be different from the shape memory material in which the ferrules are made, but for reasons of simplification, it will preferably be taken identical.
  • the sockets 41 and 42 are made of a conductive shape memory material, and shaped so as to be able to adapt closely, in a first shape memory state, to one of said pins 21, 22 contact and able to ensure the release and / or engagement of said sockets 41, 42 in a second state of shape memory.
  • the shape memory materials used to form the ferrules 31, 32 of core and mass, on the one hand, and the sockets 41, 42, on the other hand, can be identical, and, in this case, the operations engagement and disengagement are carried out at the same temperature for all components of the connection element, ferrules and sockets.
  • said shape memory materials can be different, that is to say have different transition temperatures, with the advantage of being able to dissociate, if desired, the operations of engagement and disengagement of the ferrules from those of the sockets.
  • the passage of the sockets 41, 42 from the first to the second state of shape memory can be carried out, in a nonlimiting manner, in a reversible manner simply by crossing the transition temperature of the shape memory material.
  • FIG. 1 shows that the ferrules 31 and 32 as well as, possibly, the sockets, here the socket 42, can each be constituted, in the first state of shape memory, by a substantially tubular element comprising a slot s 'extending substantially over its entire length.
  • a socket of this type called clip socket is shown in Figure 3. This particular embodiment of the active part of the ferrules and sockets, as well as the corresponding educational process, are described in detail in the patent application. European No. 86 400 560.8.
