Definitions
- the present invention relates to an increased safety connection intended for demanding connection applications in terms of user protection and environmental protection.
- Such fittings include a male end piece, a female end piece, an outer flange or groove of the male end piece, and a stop movable transversely in the wall of the female end piece to be housed in the groove or behind the flange of the end piece. male when placed in the female end cap.
- Some of these devices include a indicator to show whether the connection is correct or not, in order to reduce the risks associated with a bad connection.
- the invention is intended to satisfy both the increased security requirement in terms of connection quality and the request for an increase in the mechanical strength characteristics of a connector to contain higher and higher pressures.
- the subject of the present invention is therefore a reinforced safety connector comprising: a female end-piece defining a stage housing, a male end-piece with a collar, the outside diameters of which correspond to those of the stage housing of the female end-piece, a movable locking ring transversely in a base of the female end-piece, situated at the entrance of the housing of the latter , remarkable in that it comprises an additional locking cage, one wall of which forms a front cover at the end of the female end piece, slidably mounted on the base of the locking ring between a connection position allowing passage of the flange through the front cover of this cage, and a locking position preventing the passage of this flange through this front cover.
- the cage which covers the hollow base of the locking ring of the female end piece constitutes a reinforcement of this base, that is to say of the weakest parts of the locking which are this base and the ring which is mounted. with transverse sliding, so that the collar secured to the male end piece is practically impossible to remove from the cage.
- the cage will be made from a stamped metal sheet. It comprises, parallel to the cover and behind it, a pin made of metal wire, the elastic branches of which each define the two aforementioned positions by shape correspondence with the female end piece.
- each branch includes a cage retaining pawl on the base, each corresponding to one of the two aforementioned positions.
- FIGS. 1 and 2 are two external views of a connector according to the invention in the connection position of the cage with respect to the female end piece
- FIGS. 3 and 4 are two same views of this embodiment of the invention, the cage being in its position for locking the connection
- FIGS. 5 and 6 illustrate an alternative embodiment of a connector according to the invention, by two rear views of the two connection and locking positions of the cage according to the invention placed on the female end piece
- - Figure 7 is an external view of the first embodiment of the cage alone.
- the female end-piece shown in FIGS. 1 to 4 is a bent end-piece 1, which comprises a terminal connection section defining in known manner a cylindrical stage housing whose outer wall 2 can be seen in the figures.
- the end piece 1 At the end of this cylindrical stage housing, the end piece 1 comprises a base 3 whose shape is substantially square, which is hollow and which contains a locking ring 4 movable transversely to the housing 2 in the hollow base 3 to the against elastic members which recalls it in the high position, position in which a pusher 5 protrudes from the base 3 and is used to operate the locking ring to effect disconnection.
- a structure of this type is fully illustrated by the document FR 2 705 430.
- a cage 6 which has a front wall 7 forming a front cover provided with flanges 8 extending rearward.
- the base 3 can be housed between these edges, behind the front wall 7.
- the height of the cage 6 is greater than the dimension taken in this direction of the base 3, so that the cage can take several positions relative to this base in the direction of this height.
- the front cover 7 of the cage is provided with an opening 9 in the keyhole.
- this opening has a part 9a of circular outline and a part 9b in a U opening into part 9a.
- the front opening of the hollow base 3 has a diameter substantially identical to that of the part 9a of the opening 9 in the keyhole.
- the width of the part 9b of this opening 9 is of course less than the diameter of the part 9a, so that when the base 3 is facing this part 9b, the edges of this opening partially mask the opening front of this base 3.
- the connection of the cage 6 and the female end piece 1 is ensured by a pin 12, made of metal wire, and kept in the cage at a distance from the front cover 7 as illustrated in FIG. 7.
- This metal pin is in the general shape of U , with at the lower angles, ears 13 which penetrate into slots 14 of the side walls 8 of the cage 6.
- Each of the branches 12a, 12b, of the U has a double hanger which defines with the double hanger. of the other branch, a means of indexing in two positions the part 2 of the female end cap covered by the cage 6.
- the free end of the branch 12a is curved in a pawl 15 while the free end of the branch 12b is curved in a pawl 16 longer than the pawl 15. It can be seen in FIG. 7 that the pa - lateral king 8 of the cage 6 is scalloped in the upper part to allow the cage to be introduced onto the base 3 by sliding parallel to the front cover 7.
- the bottom of the U that this pin 12 defines is wavy, so that after having placed it in the slots 14, the two undulations are at least partially crushed from this bottom, which causes it to lengthen and cause the two ears 13 to penetrate without the possibility of leaving it, in the slots 14.
- the cylindrical part stepped 2 located behind the base 3 of the end piece 1 moves aside the branches 12 until it is located as in Figures 2 and 5 in a first indexing position in which on the one hand the pawl 15 returns over this section of the nozzle 1 and on the other hand the branches 12a and 12b tighten on this section 2 at their first hanger.
- This first indexing position is the delivery position of the nozzle fitted with the cage, and the position in which a connection is possible.
- the male end piece 10 is introduced into the female end piece, the user relatively moves the cage and the base 3 so as to reach the second indexing position defined by the two other lower hangers close to the ears 13 of the pin 12.
- the pawl 16 is released, constitutes a relative anti-sliding stop of the cage and the base 3.
- the pin has a branch 12b which, instead of having a pawl 16, has an extension 17 parallel to section 2 of the female end piece 1 when the relative position of the cage and this end piece corresponds to the first indexing, therefore to the connection position of the end piece, and which is folded elastically behind the base 3 so as to hang in a notch 18 in the wall 8 of the cage 6 when the locking position is reached.
- FIG. 3 An alternative embodiment of the cage according to the invention in which the part 9b of the opening 9 in the keyhole is bordered by a wall 20 projecting frontally from the cover 7.
- This wall 20 has for object to prohibit the passage from the connection position to the locking position of the ring relative to the female end piece if the penetration of the end piece 10 into the female end piece 1 is not complete the flange 11 being still outside the front face of the cover 7.
