Definitions

  • the present disclosure relates to an electrical female connector and to an electrical connector assembly including such a female connector and a male connector configured to be uncoupled from and coupled to one another via a mate assist lever locking mechanism. More particularly, the female connector is a sealed electrical connector.
  • Motor vehicle doors contain electrical devices such as window raisers, mirror adjusters, etc. To power and/or control these devices, sealed connectors are fitted to the door or car body. As connectors of this type have a large number of contacts, mating assistance devices are required to prevent, in particular, musculoskeletal disorders for the operators responsible for fitting them. To this end, the connectors are fitted with mate assist systems comprising a slider or a lever. In addition, waterproofing and/or dustproofing, for example, are essential to ensure that the function of these connectors remains properly fulfilled over the long term.
  • a sealed connector and an assembly comprising such a sealed connector is disclosed below in the context of seeking to improve the combined functions of mating assistance and sealing.
  • the present disclosure relates to an electrical female connector according to claim 1.
  • the watertight barrier thus formed increases the connector's resistance to water, dust, etc.
  • this type of female connector is usually equipped with an interfacial seal between the connector and a male connector (i.e., counter-connector to be mated with the female connector), and a cable seal, or rear seal, between the cable and the female connector housing.
  • a male connector i.e., counter-connector to be mated with the female connector
  • a cable seal or rear seal
  • the electrical female connector comprises, independently of each other or in combination with one or more others, one or several features according to any one of claims 2 to 9.
  • this cable connector assembly 100 is designed to connect cables (not shown) through an opening in a frame 35 of a car door or of a car body.
  • the counter-connector 2 is a male connector and comprises a male housing 3 intended to be fastened to the frame.
  • the male housing 3 is made of molded plastic and accommodates electrical male terminals (not shown).
  • the male housing 3 comprises two actuating pins 4, each extending from a male housing side face 5 essentially perpendicular to the mating direction MD.
  • the connector 1 is a female connector and comprises a female housing 6.
  • the female housing 6 is made of molded plastic and accommodates electrical female terminals (not shown).
  • An actuating lever 7 is rotatably mounted onto the female housing 6 about a rotation axis RA essentially perpendicular to the mating direction MD.
  • the actuating lever 7 is made of molded plastic.
  • the actuating lever 7 comprises two pivots 29 aligned with the rotation axis RA.
  • the actuating lever 7 provides mate assist means.
  • the female connector 1 can be mated with a counter-connector 2 (e.g., they can be brought closer to each other in "preposition").
  • the two lever arms 20 When the actuating lever 7 is in open position, the two lever arms 20 form an angle which is, for example, comprised between 40 and 90 degrees, for example close to 70 degrees.
  • the female connector 1 When the actuating lever 7 is in closed position the female connector 1 is mated with a counter-connector 2.
  • the two lever arms 20 When the actuating lever 7 is in closed position the two lever arms 20 form an angle which is, for example, comprised between 0 and 20 degrees with the mating face 10, for example close to 0 degree. In the closed position, the actuating lever 7 is flush with the female housing 6, taking up less space.
  • the female housing 6 comprises a first female housing side face 8, a second female housing side face 9 and a mating face 10 (see Fig. 4 ).
  • the mating face 10 is essentially perpendicular to the mating direction MD.
  • the first female housing side face 8 and the second female housing side face 9 extend essentially parallel to the mating direction MD.
  • a compartment 11 is arranged over each of the first female housing face 8 and the second female housing side face 9 respectively (see Figs. 1 and 11 ).
  • Each compartment 11 partially covers a respective female housing side face 8, 9.
  • Each compartment 11 comprises an external wall 32 and an internal wall 33 (See Fig. 11 ).
  • the external wall 32 and the internal wall 33 extend essentially perpendicular to the rotation axis RA.
  • a concave surface 12 is formed inside each compartment 11 (See Fig. 4 ). Each concave surface 12 extends along a portion of a first arc of a circle 13 centred on the rotation axis RA.
  • the female housing 6 comprises guiding slots 18 longitudinally extending essentially perpendicular to the mating face 10.
  • each actuating pin 4 engages a respective guiding slot 18 (See Fig. 9 ).
  • each actuating pin 4 moves along a respective guiding slot 18.
  • Each guiding slot allows a respective pin 4 to pass through an internal wall 33, so that each respective pin 4 can engage and cooperate with a cam slot 28, thereby providing a mating assistance when the actuating lever 7 is rotated from the open position to the closed position.
  • the connector 1 comprises sealing means 14 overmoulded on the female housing 6 (see Figs. 2 , 5 and 6 for example).
  • the female housing 6 is a two-component part.
  • the female housing 6 comprises a hard plastic portion 15 and the elastomeric sealing means 14 overmoulded on the hard plastic portion 15 (See Fig. 6 ).
  • the sealing means 14 comprises two lever seals 16 and an interfacial seal 17 (See Fig. 5 ). Each lever seal 16 is connected to the interfacial seal 17.
  • each lever seal 16 is connected to the interfacial seal 17 through one of the guiding slots 18 (See Fig. 6 ).
  • the female housing 6 comprises bonding surfaces 31 on which the lever seal 16 is overmoulded (See Fig. 4 ).
  • the actuating lever 7 has two lever flanges 19 and two lever arms 20 respectively connecting one lever flange 19 to a lever handle 21.
  • Each lever flange 19 is at least partially accommodated in a respective compartment 11 (In Figs 2 , 4 , 6 , 9 , 10 and 12 , the external wall 32 of a compartment 11, is removed in order to show one of the flanges 19 of the lever 7).
  • This configuration prevents the flanges 19 from moving apart. Indeed, the flanges 19 are blocked in directions parallel to the rotation axis RA by the external walls 32 on the one hand and by the internal walls 33 of the compartments on the other.
  • Each lever flange 19 has an inner face 22 facing a respective female housing side face 8, 9 (i.e., facing an internal wall 33) and an outer surface 30 facing an inner surface of the respective compartment 11 (i.e., facing the inner surface of an external wall 32).
  • Each pivot 29 extends from an outer surface 30.
  • Each pivot 29 engages a respective hole formed in the inner surface of the respective compartment 11.
  • Each lever flange 19 has a convex surface 23 that extends along a portion of a second arc of a circle 24 centred on the rotation axis RA, when the actuating lever 7 is rotatably mounted on the female housing 6.
  • Each lever seal 16 comprises at least one first portion 25 intercalated between at least a portion of said concave surface 12 and a portion of said convex surface 23, and at least one second portion 26 intercalated between each inner face 22 of a lever flange 19 and a portion of the inner wall 33 of a respective female housing side face 8, 9.
  • the first portion 25 and second portion 26 of the lever seals 16 are configured to form, between each inner faces 22 and the respective female housing side face 8, 9, a continuous sealing barrier around the rotation axis RA, at least when the actuating lever 7 is in closed position.
  • first portion 25 and second portion 26 of the lever seals 16 are also configured to form, between each inner faces 22 and the respective female housing side face 8, 9, a continuous sealing barrier around the rotation axis RA, when the actuating lever 7 is in open position.
  • each inner face 22 of a lever flange 19 has a polished area 27 onto which wipes said at least one second portion 22 of the sealing means 14.
  • This polished area 27 extends all around a cam slot 28 designed to engage the actuating pin 4 to assist coupling and uncoupling of the connector 1 and the counter-connector 2.
  • This polished area 27 promotes a better contact of the second portion 26 of each lever seal 16 on each lever flange 19 and improves tightness.
  • Lips 34 may be provided on the second portion 26 to improve water tightness and/or dust-tightness.
  • the first portion 25 and second portion 26 of each lever seal 16 form, between each inner faces 22 and the respective female housing side face 8, 9, a continuous sealing barrier around each cam slot 28, at least when the actuating lever 7 is in closed position.
  • the first portion 25 and second portion 26 of each lever seal 16 form, between each inner faces 22 and the respective female housing side face 8, 9, a continuous sealing barrier around each cam slot 28, when the actuating lever 7 is in open position too.
  • the lever flanges 19 are sufficiently thick for the pins 4 to enter the cam slot 28, but the lever flanges 19 are in continuous contact with the first portions 25 on the second arcs of a circle 24.
  • the sealing means 14 is already in place when the connector 1 and the counter-connector 2 are in preposition (i.e., with the lever 7 at 70°). And of course, the sealing means 14 the sealing is already in place when the connector 1 and the counter-connector 2 are fully mated (i.e., with the lever 7 at 0° - see Figures 12 and 13 ).
  • the cam slots 28, the guiding slots 18 and the pins 4 are located inside a watertight region delimited by the lever seals 14 and more particularly by its first 25 and second 26 portions.
