Definitions

  • the subject of the invention is a connection device between a termination of a cable and a contact element. It presents more particularly its use in the field of interconnections in the field aeronautics. Cable has metal strands held together in a cable sheath. These strands must be connected to the element of connection so that the latter can ensure the continuity of the electrical signal to a junction between the cable and a complementary device. But the materials in which they are respectively made are of natures different and have different physical properties. Now such elements and cables are subject to significant physical constraints, in terms of pressure and temperature variation due to their use on board of on-board vehicles. Therefore the guarantee of a connection permanent may not be insured.
  • the invention provides a solution using an intermediate element to compensate for effects of these temperature variations in particular.
  • a contact element provided to receive a termination of a cable in a receptacle of this element of contact.
  • the receptacle generally forms a cylindrical barrel inside from which a stripped portion of the cable can be introduced.
  • the barrel is also planned with a widening at the level of an exit of this barrel for also be able to receive a non-stripped portion of the cable.
  • the cable is retained inside the barrel because it is then crimped around the portion stripped, and around the non-stripped portion of the cable.
  • This contact element generally offers one end of contact opposite the end giving access to the opening opening onto inside the barrel.
  • This contact end generally has a shape elongated and has either a female end or a male end.
  • the contact element is made in one piece, for example it is machined or well obtained by turning. It is made of copper, and constitutes a part massive.
  • cables with copper strands cannot be used. Through therefore it is envisaged to use cables with aluminum strands, having good conductivity, contact resistance characteristics, and having a lower weight compared to that of the copper strands.
  • the barrel is crimped at a first level on the bare strands of the cable and at a second level on the cable sheath.
  • the first crimping ensures an electrical connection and both mechanical strength.
  • the second crimping seals the connection at the opening of the barrel.
  • the object of the invention is to solve the problems posed in offering a secure connection that can keep its qualities even when subjected to such pressure and temperature variations.
  • the solution implemented in the invention consists in producing an element of contact in two parts.
  • the first part is made up of contact male or female machined or cleavage and having a massive end.
  • the second part of the contact consists of a tube inside which the first part can be force-fitted. The first part is pressed into a first open end of the tube.
  • the second part forming a tube can receive at a second end the strands of the cable and also a portion of the cable not naked. This second end is crimped onto the strands of the cable.
  • the second part is made of a material similar to the nature of the strands, similar at least in terms of coefficient expansion, when this connection is subject to physical variations described above, the two elements evolve in the same way one by to each other and therefore remain in constant contact. This solution allows to obtain a sufficient mechanical and electrical connection. During shocks there is no drop in contact pressure between the strands and the walls of the tube. This improves the contact resistance and promote signal transmission.
  • Another advantage conferred by the invention is that if one still wants to improve the quality of the connection between the strands and the tube, we can very easily protect the inner walls of the tube with a layer of gilding for example. This layer can be very easily deposited and controlled, since the tube thus prepared and before mounting is open to its two ends.
  • the subject of the invention is a connection device between an element of contact and strands of a cable, the strands of the cable being made in a material with an expansion coefficient different from an expansion coefficient of the contact element, the device comprising a cooperating intermediate tube respectively with the contact element and the strands, this tube having a rigidity similar to that of the contact element, and having a coefficient of expansion similar to that of the strands, characterized in that the tube intermediate is covered internally with a ductile material and driver.
  • Figure 1 shows a contact 100 according to the interior art.
  • This contact 100 has a generally elongated shape along an axis 101.
  • contact 100 has an opening 103 inside which is inserted one end 104 of a cable 105.
  • This end 104 has a first terminal portion 106 stripped bare, revealing strands 107 of this cable 105.
  • the end 104 has a second portion 108 for which the strands 107 are protected by a sheath 109 of this cable 105.
  • the contact 100 has at a second end 110 a form of male or female termination to cooperate with a device complementary.
  • Contact 100 is made in one piece in one single material for example copper, while the strands 107 are made aluminum.
  • a layer 113 is deposited on the walls 111. This layer comprises for example gold.
  • the filing of this layer 113 in the barrel 112 is made by injection. Homogeneity control of this deposit to ensure that the layer is not just a deposit concentrated at the bottom 114 of the barrel, this barrel has a manhole 115. This manhole is formed to allow access between the interior of the barrel 112 and the outside of contact 100. The excess material which is deposited for forming the layer is evacuated through this manhole.
  • Figure 2 shows a connecting device 1 according to the invention.
  • This device 1 makes it possible to connect one end 2 of a cable 3 to an element of contact 4.
  • the end 2 has a first terminal portion 5 leaving appear strands 6 of this cable 3. Furthermore, the end 2 has a second portion 7 for which the strands 6 are protected by a sheath 8 of cable 3. The end 2 corresponds to the length of cable which is inserted at inside an intermediate tube 9 of the device 1.
  • the cable 3 extends along an axis 10.
  • the end 2 is inserted into an opening 11 of the tube 9, on the right side of this tube.
  • the opening 11 opens onto an internal channel 12 which runs right through leaves the tube 9.
  • This channel extends parallel to the axis 10.
  • the inner channel is for example cylindrical. It can present several sections of different interior diameters.
  • the tube has a first section with an internal diameter 13, and a second section with an internal diameter 14.
  • the diameter 14 is less than the diameter 13.
  • the second section of diameter 14 is no longer in a position central inside the tube.
  • the sheath 8 abuts against a setback interior 15 which is defined between the first section 13 and the second section 14.
  • the sections respectively 13 and 14 are crimped around the portions respectively 7 and 5. It is therefore retained by a double crimp.
  • the crimping of the second section of diameter 14 around the 6 bare strands of the first portion 5 ensures both the mechanical retention of the end 2, but also an electrical connection between the interior walls of channel 12 with the strands 6.
  • the crimping of the first section of internal diameter 13 around the second portion 7 of the end 2 also provides a mechanical retention function, and also guarantees the tightness of the opening side connection 11.
  • the cable 3 has for example aluminum strands and is surrounded by an insulating plastic sheath.
  • the intermediate tube 9 is him for example machined or obtained by turning in a material solid, for example aluminum. Since the materials of strands 6 are similar to those of tube 9, so they have similar expansion coefficients. That is, when they are submitted to the same constraints, they react in the same way, which means only if the contact pressure and the electrical resistance of the connection meet certain criteria under certain conditions, these criteria will be met in all types of conditions.
  • the inner walls of the channel 12 can be covered with a layer 16 in a ductile and conductive material.
  • This layer 16 can for example include silver, gold, and or tin.
  • the deposition of this layer 16 is a very easy operation since access to the interior walls of the channel 12 is allowed on the one hand on the side of the opening 11, but also to a second opening 17, on the left side of this tube 9.
  • the openings 11 and 17 are parallel to each other, and orthogonal to the axis 10.
  • this layer 16 is deposited on the tube 9, it can be mounted both on the cable and then fitted with its contact element 4.
  • the contact element 4 has a tubular shape and has at a end a male or female connection means 18 for cooperating with a complementary device.
  • this means of connection 18 is a male connector.
  • the contact element 4 is for example obtained by machining in a solid material such as copper. Indeed, the copper has good conductivity and contact resistance which limits signal losses at the junction with the device complementary.
  • the contact element 4 is forcibly mounted on the tube 9. They are each made of a material with technical characteristics different, especially from the point of view of the coefficient of expansion. Strands 6 and the tube 9 having a similar coefficient of expansion, therefore the coefficient of expansion of the strands is therefore different from that of the element of contact 4.
  • the contact element 4 and the tube 9 are rigid similar, they each constitute a massive piece. And since they are both massive, when a mechanical contact is established between them, even if the external variations induce differential dilations, they do not prevent that the contact pressure always remains sufficient to guarantee the connection.
  • the channel 12 has a third section of which an internal diameter 19 is slightly less than an external diameter 20 of the inserted part 21 of the contact element 4.
  • the entire periphery outside of part 21 is constrained over the entire inner wall at the level of this third section 19. The fact that part 21 is inserted by forcing against the interior walls of channel 12 ensures both good mechanical strength, but also good electrical contact.
  • the inserted part 21 is delimited by a collar 22 which comes lean against an outer periphery of the second opening 17.
  • the presence of this flange 22 provides an additional means for guarantee the tightness of the connection at the second opening 17.
  • the part 21 is intended to receive in a barrel of this part 21 the second end having the opening 17 tube. In this case, the tube is then forcefully inserted into the barrel of part 21.
