Definitions

  • the invention relates to electrical connectors with two plug-in connection blocks, and more particularly relates to a connection block for such a connector, of the so-called modular type, comprising a rectangular box whose two opposite faces have longitudinal projections delimiting parallel corridors and flat wafers of insulating material, each wafer occupying one of said corridors, comprising a single row of parallel passages for receiving contact terminals and having a large face cut out in a front part to constitute pawls of individual retention of the terminals by snap-fastening in the terminal holes, the housing and each wafer comprising cooperating coding means authorizing the complete introduction of a wafer only in one orientation.
  • a block of the kind defined above can easily be designed to incorporate wafers giving the terminals a pitch of distribution of the contacts variable from one wafer to another (but obviously equal for the cooperating wafers of the two blocks of the same connector ). It is also possible to omit some of the wafers in applications where the corresponding terminals are not necessary. All these features make such a connector particularly advantageous in many fields, such as the automobile and workshops with electronically controlled machine tools and / or robots.
  • the invention aims in particular to eliminate this risk.
  • it offers a connection block of the above type, characterized in that the projections occupy the entire depth of the housing so as to guide each wafer as soon as it is introduced into the housing, in that the pawls are recessed relative to at the front of the wafer and in that the housing comprises on one of the long sides a step for abutment of any pawl of the wafer raised by incomplete depression of a terminal of the wafer, limiting the bending deformation of a ratchet.
  • the invention is of particular interest in connectors whose male terminals are tongues whose width is in the direction of the rows and whose female terminals are of the cage type.
  • the housing of each block advantageously has side walls connected by a bottom pierced with rows of slots each corresponding to a location of wafer; giving the slots a length greater than the spacing between two passages, it is possible to place in the housing wafers having any one of several different distribution steps, intended for terminals of different size in the direction of the rows: it is for example possible to use female terminals having 2.8 mm and 1.5 mm wide, distributed respectively in steps of 5 mm and 3.33 mm (i.e. such that three terminals in short pitch occupy the same length as two terminals in long pitch).
  • each of the small faces of each wafer carries an elastic retaining finger having at the rear a spout intended to engage in an opening of the housing, framed by two rigid wings. These wings avoid jamming of the finger, for example by a wire engaged between the finger and the body of the cake.
  • the polarizing means may comprise, on one of the small faces of each wafer, a groove or rib placed on one side of the median plane for one type of wafer, on the other side for the other type; only one of the faces of the housing has grooves or ribs having a corresponding location.
  • the polarizing means thus fulfill a double function.
  • the male connection block 10 shown in FIGS. 1 to 3 is intended to receive female terminals of the cage type and to be plugged into a complementary female connection block 12 (FIG. 6) equipped with male terminals with contact strips or tabs.
  • a complementary female connection block 12 FIG. 6
  • Such a block can in particular be used to equip motor vehicles.
  • the block 10 comprises a housing 14 intended to receive one or two wafers 16 (the housing can be designed to receive a higher number of wafers).
  • the housing 14 and the wafers 16 may be made of polymerized synthetic material containing fillers.
  • the housing 14, of rectangular section, has sides connected by a bottom pierced with rows of parallel slots 17. It comprises means defining guide tracks for the pancakes 16 from the start of their introduction. In the case of a housing with two pancakes, these means comprise a single pair of guide projections 18 formed along two opposite sides of the housing and pairs of guide notches 20 located at the intersection of the long sides and the small sides of the shoemaker, both of constant section and corresponding to that of grooves made in the dihedrons of the pancakes.
  • a row of several passages, of rectangular section, each intended to receive a terminal 22 (FIGS. 1 and 9) is formed.
  • the maximum insertion position of the terminal is determined by its support against an abutment flange 24 provided on the wafers.
  • One of the large faces of each wafer is cut out and constitutes elastic pawls 26, the spout of which is intended to engage in one of the two locking holes 28 that each terminal has, on two opposite sides.
  • the pawls 26 end in withdrawal with respect to the front end of the wafer and to the abutment rim 24.
  • the pawl extends beyond the spout so that its bending causes a displacement of its end which is greater than the displacement caused by the spout, which is a factor favoring the detection of non-snap-fastening.
  • a keying groove 30 offset relative to the median plane of the wafer and intended to slide on a keying rib 32 provided on one side of the housing 14
  • the housing only intervenes to prevent the insertion of the first wafer when one of its pawls remains raised.
  • Means are advantageously provided to avoid likewise the insertion of the second pancake and possibly of the following ones. In the case shown in Figure 6, these means consist of a step 36 on each of the wafers.
  • each of the small faces of each wafer is cut to form an elastic finger 38 having a locking spout intended to engage in a corresponding opening 40 of the housing 14.
  • each finger 38 is advantageously framed laterally by two protective wings 42 ( Figure 2).
  • the means making it possible to fix the male block to the female block may include extensions 44 inserted between the fingers 38 and the body of the pancakes, preventing the withdrawal of the pancakes.
  • Figures 7 and 8 show alternative embodiments in which the steps 36, prohibiting the insertion of wafers other than the first when a pawl remains raised, are replaced by other means.
  • each wafer which separate the passages have an inclined edge 46 and that of the large faces of the wafer which carries no pawls ends at about two-thirds of the height of the wafer, so as to constitute a support shoulder 48.
  • the housing 14 has walls 50 whose end constitutes a stop.
  • a connector can consist of a male block of any of the types which have just been described and of a female block 12 of the kind shown in FIG. 6.
  • This female block also has sides and a bottom 52 which, this times, is far from the entrance of the block.
  • the slots 17 formed in the bottom of the housing 14 and 54 in the bottom 52 are placed in coincidence. Their width is such that they can allow passage to the tabs of male terminals 56 retained in the wafers of the female block 12 and their length is such that they occupy most of the length of the row of slots.
  • Figures 3 and 5 show, by way of example, rows of three slots 17, while the housing 14 allows to receive wafers having six passages.
  • This arrangement of the slots makes it possible to place, in a given housing, any one of several types of wafer, having transverse passage dimensions and a number of different passages. It is thus possible, depending on the intensity of the current to be passed, to provide wafers intended for terminals having a width of the contact area l varying from one wafer to another, but the same thickness.
  • these terminals can be formed by folding a strip doubling the thickness of the tongue, then cutting the end of the tongues.
