Definitions
- the subject of the present invention is a method for improving a electrical connection between a contact and strands of a cable. She also has for subject a connector assembly thus obtained. She finds more particularly its use in the aeronautical field where the material embedded with such connector assemblies is often subject to strong variations in physical constraints (temperature, pressure, ). However, the different elements of these connector assemblies are not all made of the same materials. Each material has a coefficient of specific expansion in response to these variations in temperature and pressure. It may result that contact between two materials with different coefficients of expansion can be in contact with one of the other under certain temperature and pressure conditions and no longer be in contact with each other under other conditions.
- connection between a cable termination and a contact used to form a connection plug for this end of the cable, it is generally expected to form a contact in which a barrel is dug at a first end to receive conductive strands of the cable.
- This contact has at a second end a male shape or female to be able to be connected with an additional device.
- the first end of the contact is preferably crimped around the strands of the cable. But despite this crimping, we risk getting connections defective when subjected to variations in temperature and pressure.
- Another prior art solution consists in manufacturing a ring by machining or stamping in a material with expansion coefficient intermediate. And then this ring must be force-fitted to inside the contact to narrow the opening and thereby decrease the opening of the barrel supposed to receive the strands of the cable.
- Such a solution can be effective and reliable but it also poses a problem because the realization of rings is an additional step.
- the precision of the necessary tools is expensive, and the risks of damaging the barrel during assembly are important.
- the contacts generally having an opening of about 1 millimeter in diameter, mounting a ring in this opening becomes very meticulous and therefore requires long steps. In the event that the ring is incorrectly mounted inside the contact barrel, this contact is permanently rendered unusable. There is therefore a reject rate important with this technique.
- the object of the invention is to solve the problems posed, namely to propose a reliable connection between a contact and a cable, while proposing a means of mounting and easy realization of such a connector assembly.
- the invention provides for stamping a metallic layer of material ductile against a contact wall.
- the metal layer is stamped against an interior wall of the barrel receiving the strands of the cable.
- the subject of the invention is a method of improving a connection between a contact and a cable comprising strands, the strands of the cable being intended to cooperate with a wall of the contact, characterized in that that an internal metallic layer is pressed against this wall to make the strands cooperate with this metallic layer.
- the subject of the present invention is a method for improving a connection between a contact and strands of a cable.
- the first end of the contact may be male and have a outer wall on which the strands of the cable can be supported.
- this first end of the contact can be female and in this case it has a barrel inside which are inserted the strands of the cable. cable strands.
- the strands of the cable come into contact with an interior wall of the barrel.
- the method according to the invention plans to stamp an intermediate metallic layer of ductile material on the contact wall, which must then be brought into contact with the strands of the cable.
- Figures 1 to 4 show a female contact 1 comprising a cavity 2, or was 2, to receive a cable 3 shown in Figure 4.
- the object of the invention is to allow the drawing of a layer metal on the contact wall being intended to receive the strands of the cable.
- Stamping consists of pressing a sheet against a wall of the contact, starting by pushing the center of the sheet inside cavity 2.
- a means for stamping 5 is specific to the type of contact.
- Contact 1 is elongated along an axis 6, and cavity 2 forms a barrel of cylindrical shape having an opening 7 perpendicular to this axis 6. Parallel to this axis 6, the barrel 2 has walls 8 forming a periphery of the cavity 2. The walls 8 are provided to cooperate with strands 9 of the cable 3.
- the metal layer 4 is obtained from a film made of a ductile material, namely, that it can be stretched without breaking.
- This layer can be made from silver or tin.
- a silver film with a thickness of of the order of 0.1 millimeter in the case where contact 1 which is to receive this metallic layer has dimensions of the order of 1 millimeter in diameter concerning the opening 7, of the order of 2 to 5 millimeters deep for the walls relative to the axis 6, and these walls 8 themselves having a thickness of the order of 0.1 millimeter.
- the stamping means 5 preferably comprises a matrix 10 and a punch 11.
- the punch 11 is used to push the metal layer 4 against the walls 8.
- the matrix 10 serves to retain the contact 1 in a position given relative to the punch 11 which is in motion.
- the matrix 10 in this case presses on external walls 12 of contact 1.
- the punch 11 is preferably made of hardened steel to give it high resistance to wear.
- the film presented opposite the opening 7 is square, and a center of this square is centered relative to the center of the opening 7.
- the punch 11 is itself centered along the axis 6.
- the film formed by the metal layer 4 driven by the punch 11 is disposed along the walls of the punch 11 and the punch 11 entering the cavity 2, this metal layer 4 is plated by the punch 11 on the walls 8. Under the pressure of the punch 11, the film is entrained in the cavity 2, but also it undergoes an elastic deformation which eventually leads to a thinning of the layer of plated film definitely against the wall 8.
- a surface formed by this film 4 is clearly greater than the opening 7. So when the punch 11 drives a central part of this film 4 inside the cavity 2, a portion 13 of this film remains outside of the opening 7. This excess metal layer 4 is then pressed against of the edges 14 of the opening 7 by a recess 15 of the punch 11. This surplus portion 13 is as shown in Figure 3 broken by the displacement of the die 10 relative to the punch 11 and to the contact 1 nested one inside the other.
- the matrix 10 is raised along the perimeter outside 12 parallel to the axis 6 in the direction of the opening 7. Thus the part of the additional portion 13 protruding from the rim 14 is severed during the scissor movement made by the matrix 10 relatively at the offset 15. Thus a clear drawing of the layer is obtained metal 4 inside the cavity 2.
- this punch 11 is removed parallel to the axis 6.
- an orifice may possibly be provided exhaust air 17 as shown in Figure 4. This orifice 17 therefore connects the cavity 2 at the outer wall 12.
- the contact 1 thus prepared is thus improved to ensure the connection with the strands 9 of the cable 3.
- the strands 9 are made of aluminum and the contact body 1 is made of copper, then the metal layer 4 deposited in silver or tin provides a better continuity in the electrical contact established between the strands 9 and the contact 1.
