Definitions

  • the invention relates to the field of connectors, and in particular that of automotive connectors.
  • the invention relates to a connection assembly, female and male terminals and a method of mounting a female terminal, for use in power connectors.
  • these connectors When it is necessary to integrate connectors into the wiring networks intended to transmit currents, these connectors must be provided with terminals of size and section large enough to transmit these strong currents without excessive heating. Thus, for example, it may be necessary to use male terminals whose section can reach 113 mm 2 or more. Likewise, the female terminals must be able to receive male terminals having such sections and be protected, in particular when they are used at voltages greater than 60Volts.
  • the invention aims to at least partially limit this risk of electric shock.
  • the female electrical terminal also optionally includes one or other of the characteristics set out in claims 2 to 5, considered in isolation or in combination with one or more others.
  • the finger of the protective element hinders, or even prevents the insertion of a finger or a tool inside the contact portion of the female terminal. This at least partially limits a risk of electrocution by contact with the internal surface of the contact portion of the female terminal.
  • the male electrical terminal comprises a substantially cylindrical pin, extending longitudinally parallel to the coupling axis when the male electrical terminal and the female electrical terminal are coupled, this pin having a free end, as well as an external surface suitable for establish electrical contact with the internal surface of the female electrical terminal.
  • the male electrical terminal optionally includes a pin comprising an electrically insulating crown, surrounding an entrance to the cavity, at the free end of the pin.
  • connection assembly includes the characteristic set out in claim 9.
  • the invention is a method of mounting a female electrical terminal, as mentioned in claim 6.
  • this process includes the characteristic set out in claim 7.
  • connection assembly 1 An example of a connection assembly 1 according to the invention is shown in the figure 1 . It includes a male connector housing 2 and a female connector housing 3 (not shown in the figure 1 , see figure 2 ).
  • the male 2 and female 3 connector housings are essentially made of an electrically insulating material.
  • Two male electrical terminals 4 connected to electrical cables 5 are mounted in the male connector housing 2.
  • Two female electrical terminals 6 connected to electrical cables (not shown) are mounted in the female connector housing 3.
  • the two electrical terminals females 6 intended to be coupled, along a coupling axis A, each respectively to a male electrical terminal 4 mounted in the male connector housing 2.
  • On the figure 1 only a female electrical terminal 6 is shown.
  • the female electrical terminal 6 comprises a fixing portion 7 and a contact portion 8.
  • the fixing portions 7 and contact 8 are formed in this example from a single piece which can be made of an electrically conductive material. This monobloc piece is formed from a cut and curved sheet.
  • the fixing portion 7 is shown on the figures 1 , 4 and 5 with crimping fins 9 intended to mechanically attach the female electrical terminal 6 to a cable of an electrical network (not shown).
  • the crimping fins 9 are shown in the open position, before crimping on a cable.
  • the contact portion 8 has an essentially tubular shape extending longitudinally parallel to the coupling axis A, between a free end 10 and an end mechanically integral with the fixing portion 7. It has an internal surface and a surface external. It comprises a tubular ring 12 connected to the fixing portion 7. It also includes elastic contact tongues 13 extending, essentially longitudinally parallel to the coupling axis A, from the ring 12 towards the free end 10.
  • Each tongue 13 has a substantially rectilinear portion connected to the ring 12 and a curved portion 14 towards the free end 10.
  • the curved portion 14 has a convex contact surface directed towards a longitudinal central axis of the contact portion 8 (the longitudinal central axis coincides on the Figures 4 and 5 with the coupling pin A).
  • the tongues 13 are distributed in an essentially uniform manner on one edge of the ring 12. They are spaced regularly. In other words, a slot 15 separates two neighboring tabs 13.
  • the female electrical terminal 6 also includes a protective housing 16, made of an electrically insulating material.
  • This protective housing 16 can also be used for the retention of the female electrical terminal 6 in the female connector housing 3.
  • this protective housing 16 is for example in the form of an essentially cylindrical cap extending longitudinally parallel to the coupling axis A. It has two diametrically opposite openings 17 intended to receive hooks 18 carried by elastic tabs 19 integral with the female connector housing 3.
  • the female electrical terminal 6 can be mounted and clipped into the female connector housing 3.
  • the protective housing 16 covers, by its cylindrical wall 20, essentially the contact portion 8, and by cornices 21 extending radially inwards from the cylindrical wall 20, the free end 10 of the contact portion 8, and in particular the free end of at least some of the elastic contact tabs 13.
  • the cornices 21 leave a central passage for inserting a pin 22 of a male electrical terminal 4.
  • This passage can correspond for example to a diameter of 12 , 3 mm, that is to say greater than that which would meet the IP2X standard (which limits the dimensions of this type of passage to prevent a user from being electrocuted by inserting the end with a finger 23).
  • the female electrical terminal 6 also includes a protective element 24 made of electrically insulating material (see Figures 1 to 7 ).
  • the protective element 24 comprises a base 25 and a finger 26, both essentially cylindrical, extending longitudinally parallel to the coupling axis A.
  • the base 25 has a radius greater than that of the finger 26.
  • the finger 26 has, at its free end 27, an apical surface essentially perpendicular to the coupling axis A.
  • the protective element 24 includes attachment means.
  • these attachment means are in the form of three elastic fixing lugs: two internal fixing lugs 28 and an external fixing lug 29 (see also figure 6 ).
  • the internal 28 and external 29 fixing lugs extend longitudinally essentially parallel to the coupling axis A.
  • One of the longitudinal ends of the internal 28 and external 29 fixing lugs is connected to a flange 30 extending radially towards the exterior from the base 25.
  • the other longitudinal end is free and provided with a hook 31.
  • Each hook 31 forms a lug adapted to be inserted in a slot 15 between two tabs 13, at the base of these, in abutment on the ring 12.
  • the lug of each internal fixing lug 28 therefore projects on an external face of each internal fixing lug 28.
  • the lug of the external fixing lug 29 makes projection on an internal face of the external fixing lug 29.
  • Two diametrically opposite notches 32 are formed in the base 25 to allow each of the internal fixing lugs 28 to flex respectively towards the longitudinal central axis of the contact portion 8.
  • the protective element 24 even by pressing on the free end 27 of the finger 26, it remains practically impossible to move the protective element 24 and to touch a contact tab 13. It will be noted that it is preferable, because easier, to mount the protective element 24 before the crimping operation of a cable at the fixing portion 7, that is to say when the crimping fins 9 are open. It will also be noted that the base 25 is shorter (parallel to the coupling axis A) in a lower sector than in an upper sector (the lower sector being located opposite, with respect to the internal fixing lugs, of the sector upper which has the external fixing tab). Thus, the insertion of the protective element 24 in the contact portion 8 is made easier.
  • the protective element 24 is optional. We will choose to mount it, or not, depending on the application that will be made of the female electrical terminal 6 and the risk of electrocution incurred related to the use made of the female electrical terminal 6.
  • the protective element 24 When the protective element 24 is mounted on the female electrical terminal 6, as shown in the figure 7 , the distance between the cornices 21 and the end of the finger 26 is reduced enough to meet the IP2X standard.
  • the male electrical terminal 4 has a general structure of a type already known (see in particular the figures 2 and 8 ). Only the specific aspects of the invention will therefore be described here.
  • the male electrical terminal 4 comprises a substantially cylindrical pin 22 extending longitudinally parallel to the coupling axis A, in the direction of a free end 33 intended to engage in the female electrical terminal 6 and establish contact electric inside the contact portion 8 thereof.
  • This pin 22 is formed in a bar of electrically conductive material.
  • An electrically insulating ring 34 is mounted on the free end 33.
  • An end portion of the pin 22 is pierced, for example by boring, with a central cylindrical cavity 35 extending parallel to the coupling axis A. This cavity 35 is extended through the crown 34 by a passage.
  • each male electrical terminal 4 engages respectively in the contact portion 8 of a female electrical terminal 6 (see figure 2 ).
  • the finger 26 then enters through the passage formed in the crown 34, then in the cavity 35.
  • the electrical contact between the external surface of the pin 22 of the male electrical terminal 4 and the internal surface of the contact portion 8 of the terminal female electrical 6 is established on at least one contact point 36 located, in projection on the coupling axis A and starting from the free end 33 of the pin 22, essentially at or beyond the bottom of the cavity 35.
  • the current lines can pass through a path corresponding essentially to a solid section of the pin 22 (a section for example of 113 mm 2 ).
  • This type of configuration is obviously more favorable for the passage of strong currents compared to an electrical contact which would be made at the level of the cavity 35 and which would therefore correspond to a disc having a surface, for example of 84.7mm 2 , therefore with a much smaller section than the maximum section of the spindle.
