Definitions

  • the present invention relates to electrical connectors of the type comprising an insulating housing pierced with parallel passages for receiving electrical terminals and a retention plate insertable in the housing to a front position in which it is retained, said plate being pierced with holes reception of the terminals, distributed along the same network as the passages and extending forwards by elastic fingers for retaining the terminals by snap-fastening, the fingers having a shape adapted to that of the passages so as to be able to penetrate the passages and be retained there in the position where they hold the terminals when the retention plate is in said front position.
  • a description of a connector of this kind can be found in document FR-A-2626720 by the applicant.
  • connectors of the above type are widely used, both in the case where the housing is rectangular and has terminals distributed in a rectangular or staggered network, as in the case of a so-called round housing. .
  • These connectors can have a relatively simple constitution and allow high densities of distribution of the terminals.
  • the current connectors of the above type have drawbacks.
  • the first solution complicates the realization.
  • the second hardly makes it possible to arrive at an energetic retention of the terminals in a precise longitudinal position.
  • the present invention aims in particular to provide an electrical connector of the type defined above, guaranteeing the retention of the contact terminals efficiently and precisely, and yet very simple.
  • the terminal retention means are entirely on the retention plate, the passages of the housing having only a role of confirming the latching.
  • each hole is advantageous to provide each hole with two opposite fingers, the fingers equipping a determined hole being oriented at 90 ° from the fingers equipping the four adjacent holes.
  • the retention plate may include means allowing it to be locked directly on the insulating housing in the front position: this avoids the need for additional locking members. Consequently, in a connector according to an advantageous embodiment, the retention plate is provided with locking means which cooperate with the side wall of a cavity formed in the insulating housing to receive the plate. These means make it possible to prohibit the backward movement of the plate relative to the housing from the front position, for which the plate is in abutment against a transverse partition, which can be viewed as the bottom of the housing.
  • the connector is made removable without the use of a tool.
  • the section has a circumferentially offset portion of the pawl and the lug and the wall of the housing has a notch for passage of the offset portion, allowing to exert under this portion an inward bending force to the help with your finger.
  • the connector shown schematically in the figures is a base, the contact terminals of which consist of pins distributed in a square network.
  • the invention would also be applicable to a plug and / or to a connector provided with terminals constituted by sockets.
  • the invention is of particular interest in the case of low-profile terminals, it is also applicable to the case of terminals manufactured by cutting and rolling of strip.
  • the connector includes a housing 10 and a plate retention 12, both in insulating material, for example in thermoplastic or thermosetting material reinforced with fillers, such as fiberglass.
  • the housing 10 shown can be viewed as having a partition 14 pierced with terminal receiving passages 16 (only one of which is shown) and a rear side wall 18 delimiting a receiving cavity for the retention plate 12.
  • the connector being a base , it further has a front sleeve 20 carrying means for fixing a complementary connector and which, in the illustrated case, consist of a thread.
  • staged passages are regularly distributed for receiving the barrels of the terminals.
  • the retention plate 12 has, for its part, a solid part 22 in the form of a disc intended to bear against the partition 14 of the housing and a rear skirt 24.
  • the massive part 22 is pierced with holes 25 for receiving terminals, having the same distribution as the passages. Each of these holes has a shoulder 26 directed towards the rear and intended to constitute a stop for the corresponding terminal.
  • the plate is extended, beyond the solid part 22, by sets of locking fingers 28 thickened at their free end and the elasticity of which tends to keep them in a position where their end, constituting snap-on spouts, delimits a section smaller than that of the terminal barrel.
  • Each set will generally have two diametrically opposite fingers 28.
  • the two fingers associated with a hole will generally be oriented at 90 ° from the fingers associated with the adjacent holes, in the case of a square or rectangular network.
  • Each terminal 16 has a step, which in the illustrated case is formed by the flank facing towards the front of a collar 30.
  • the part of the barrel of the terminal placed in front of the collar has a smaller diameter, sufficiently small so that '' it is possible to introduce the terminal beyond of the shoulder of the hole 26.
  • Each terminal further comprises a groove with a V- shaped profile, intended for the snap-fastening of the end beaks of the fingers 28.
  • the front wall of the groove constitutes a shoulder for hooking the end beaks of the fingers 28
  • the distance between this shoulder and the step corresponds to the distance between the shoulder of the hole and the location of the spouts.
  • the retention plate 12 is provided with locking means cooperating with the side wall 18 of the housing. These means comprise a circumferential section of the rear skirt, delimited by slots 32, parallel to the direction of insertion.
  • the section 32 includes a lug 34 intended to snap into a circumferential groove 36 of the housing ( Figure 2).
  • the section further carries a pawl 38 intended to engage in a longitudinal slot 40 of the housing.
  • the longitudinal development of the light is such that the pawl can move freely between a rear position ( Figure 3) where it retains the retention plate in a position where the fingers are free and allow the insertion and removal of the terminals and a position corresponding to the support of the plate against the transverse partition 14 of the housing 10.
  • the housing is advantageously formed to allow to flex easily the section carrying the pawl and the lug with the finger.
  • a rear notch 42 is provided in the side wall 18. It allows to press with the finger on a fraction of the section which can be provided with a flange.
  • Figures 3 and 4 show two diametrically opposite sections, facilitating the release by clamping the sections between two fingers.
  • the connector is then generally completed by sliding a grommet made of flexible material in the skirt of the plate and by blocking it with a cap, screwed for example onto a thread of the side wall 18 of the housing.
