  • these devices comprise a male box element intended to be engaged in the female box and which comprises guide means, female contact members and means for blocking these in channels intended to receive them.
  • the female contact members are not well positioned in the channels, it is often difficult to check. In addition, if it is necessary to dismantle and change a female contact member often it must be damaged or, at least, the blocking means provided in the channels.
  • One of the aims of the present invention is to remedy these drawbacks.
  • the device according to the invention is of the type comprising a housing element having a body of generally parallelepipedal shape with four side walls and a bottom in which are erected male electrical contact tabs, said body comprising partitions standing up from the bottom and forming conduits in which the tongues extend, each conduit being intended to receive a female electrical contact member having, at its corresponding end, an elastic clamp intended to grip a tongue, and a locking member being provided for blocking said female electrical contact members in the conduits, said locking member being formed of a body having, of on the one hand, means for guiding it on the housing element and, on the other hand, means for blocking it in the locked position on said housing element, characterized in that each partition has, in the vicinity of its free end, a part having a thickness less than that of its end adjacent to the bottom, each female electrical contact member having, at least, one lug, the free projecting end of which is turned on the side opposite to the elastic clamp, the locking member comprising, at least, a fin intended to cooperate with the free end of the
  • the locking member also constitutes a pushing and insertion member for the electrical contact members in the conduits. It is thus possible to envisage using the device for relatively large intensities, the tongues having corresponding thicknesses.
  • the female electrical contact member comprises two ears arranged on two opposite sides, while the locking member comprises, for each conduit, two fins, the interval of the corresponding faces of the partitions corresponds to the distance separating the external faces of the fins intended to be inserted in said interval and the space separating the free ends of the ears is greater than the spacing of the fins and less than the interval separating the partitions.
  • the ears elastically spread the fins which return to their initial position when the female members are in a position in which the free ends of the fins can abut against the free ends ears and thus be pushed to occupy a position in which the locking member can be blocked.
  • the fins are spaced apart and cannot be inserted between the partitions so that said member cannot be suitably engaged and blocked on the housing element.
  • the locking member comprises a locking tab constituted by a U-shaped element, one wing of which is, at its end, secured to the body, while the other wing is free and has a locking pin in the vicinity from its free end, the housing element having a housing intended to receive the blocking tab and having a stop with which the lug cooperates in the locked position, the width of the housing being slightly less than the thickness of the tab blocking in order to be able to maintain the locking member in a waiting position.
  • Figure 1 is an exploded perspective view of a device according to the invention.
  • Figure 2 is a plan view of a female electrical contact member for use with the device.
  • Figure 3 shows, in perspective, on a larger scale with a cutaway, part of a female housing element.
  • Figures 4, 5 and 6 are sectional views showing the establishment of the female contact member.
  • Figure 7 is a sectional view along line 7-7 of Figure 4.
  • Figures 8 and 9 are sectional views showing the blocking of the locking member.
  • Figure 10 is a sectional view showing that the locking member can not be put in place if the electrical contact member is not properly inserted into the corresponding conduit.
  • Figure 11 is a schematic sectional view of an alternative embodiment.
  • the electrical connection device shown in the figures comprises a female housing element 1 having two parallel side walls 3 and 6, two end side walls 2 and 8 and a bottom 4 from which a series of male contact tabs are erected. 5.
  • the female housing element is fixed.
  • These male tabs 5 may be contact members carried by an element of a complementary housing, may be integral with the bottom 4 and be connected to a printed circuit or the like.
  • Each male tongue 5 is separated from the neighboring male tongue by a partition 7 which extends to a certain level from the walls 3 and 6.
  • Each partition 7 has an end 7 a having a thickness less than that of the end adjacent to the bottom 4 and connected on one side by a ramp 7 b and on the other side by a ramp 7 c .
  • the partitions 7 delimit conduits 13.
  • the housing element 1 is intended to receive electrical contact members 10 comprising a body with, at one end, crimping lugs 11 and 12 making it possible to fix respectively the stripped strands 14 of an insulated conductor 15 and the latter.
  • the member 10 On the side opposite to the crimping lugs 11 and 12, the member 10 is terminated by an elastic clamp 16 intended to elastically grip a male tongue 5.
  • the body of the member 10 is provided with ears 17, the free ends of which are directed towards the legs 11 and 12.
  • the free edge of the element 22 facing the wall 6 forms a stop 24.
  • the housing element 1 is completed by a locking member 30 for the members 10.
  • the locking member 30 consists of a molded plastic body having, on one side, elastic fins 31 which delimit channels 32 between them.
  • the body of the member 30 has two walls 35 which are separated from the fins 31 by notches 33 corresponding to the thickness of the wall 6, each wall 35 having a guide projection 37 which forms a bend 38.
  • a locking tab 39 is provided which affects the U shape, the end of which free of one of the branches is secured to the body of the member 30, while the other free branch has, near its end, a locking pin 40 having a ramp 40 b terminated by a steep 40 a on the side of the free end of said branch.
  • the fins 31 have a length such that, when the locking member 30 is put in place, said fins extend along the parts 7 has partitions 7 to vicinity of the ramps 7 c , 7 d .
  • the female contact member 10 is engaged in a conduit 13 so that its clamp 16 abuts against the tongue 5, the locking member 30 is then put in place and the free ends of the fins 31 abut against the ears 17 (fig. 5) and push the member 10 so that its clamp 16 encloses the corresponding tongue 5 (fig.6).
  • the face of the walls 35 When the locking member 30 is put in place, the face of the walls 35, turned towards the side of the fins 31, cooperates with the external face of the wall 6, while the free edge of said walls bears against the corresponding face of the ribs 20 and the projections 37 against the corresponding faces of the element 22.
  • the locking tab 39 comes to be placed in the housing 21.
  • the distance between the stop 24 of the wall 6 is slightly less than the thickness of the locking tab 39 so that, when the member 30 is engaged in the housing element 1, it can occupy a waiting position (see FIG. 8) in which the ramp 40b has not crossed the stop 24 .
  • the members 10 can easily be inserted by engaging them in the guide channels 32 until the ears 17 come to cooperate with the edge of the fins 31. Then, the member 30 is pushed so that the abrupt 40 a comes to cooperate with the stop 24.
  • FIG. 10 shows, in fact, that the ears 17, during the engagement of the members 10, elastically spread the fins 31, the latter then no longer being able to be inserted between the parts 7 has partitions 7.
  • the fins 31, by cooperating with the free end of the balls 17 facilitate the insertion of the members 10 into the conduits 13 by allowing the engagement of the tongues 5 in the clamps 16.
  • FIG. 11 shows a variant of the invention in which the references given in the preceding figures have been used to designate the corresponding parts, but assigned the letter "a".
  • Figure 11 shows a housing part of which has a tab 5 is intended to be electrically connected to a clamp 16 has an electrical contact member 10 has female.
  • the member 10 comprises a one ear 17a, while the locking member 30 a has only one fin 31 a. As shown in Figure 11, this arrangement offers the same security and the same advantages as that of the previous figures.
  • FIG. 1 to 10 there is shown an embodiment in which the housing 1 is intended to receive three members 10, this could, of course, be arranged to receive a larger number, the member 30 being able to be larger or be made up of modules arranged side by side.
  • the device passes through a particularly advantageous application for relatively large electrical currents, the tabs 5 being able to have a large thickness.
