    Quick connector for pipes
    The present invention refers to a connector for pipes of the typecalled "fast" connector for pipes. Said type of "fast" connections forpipes comprises a male pipe, a female pipe and aconnection device, usually arranged in the female part, which is activated fromimmediately when the female part receives the male part, retaining said part
    10 male
    The present invention is especially suitable for applications in the automotive industry and in particular for fuel pipes and pipes in selective catalytic reduction (SCR) systems, although the invention does not remain
    15 necessarily limited to that application.
    Quick connectors are known which comprise one or two push buttons associated with an elastic element.
    20 Push button connectors generally block the male connector in an unbalanced manner, only on one side.
    The connectors of two pushbuttons and some of a pushbutton block the male connector by symmetrical points (180º apart), leaving opposite points unblocked.
    25 However, it would be advisable to balance the locking areas of the connector and increase the retention surface to obtain a more uniform retention.
    In order to provide a solution to the problems set forth above, the present invention gives
    30 a quick connector for pipes is known, of the type comprising a male part and a female part and a retention device of said male part in said female part, said device being disposed inside the female part, the device providing the retention of elastic elements that are activated by inserting the male part into the female part to retain the male part, and arranging the device to
    35 minus a push-button that deactivates the retention device, characterized in that the retention device comprises three pins, each pin having a


    less a passage ramp for the male part and push-buttons at their ends that exert an action of separation of the pins, moving them radially with respect to the female part, allowing the release of the male part.
    5 Preferably said three pins are articulated with each other. Preferably said three pins of the retention element are elastic and deform allowing a passage hole for the male part when pressing the buttons.
    10 Preferably, each of said passage ramps comprises a wedge-shaped part located on the inner side of the connector for its retention. Preferably the female part comprises holes through which the protrusions protrude.
    buttons of the retention device, allowing the actuation of the buttons with
    15 one hand. Figure 1 is a perspective view of a connection made in an embodiment of the connector according to the present invention.
    Figure 2 is a side sectional view of the connection of Figure 1, the internal elements of the connection being visible. Figure 3 is a perspective view of the female part with the connection device. Figure 4 is a view of the front frontal elevation of the mouthpiece of the female part in which the elements that hide the parts of the connection device have been removed. Figure 5 is a perspective view of the retention device.
    30 Figure 6 is a front elevation view of the retention device. Figure 7 is a perspective view of the male part of the quick connection shown in Figures 1 to 3.
    An example of a quick connection embodiment with a connector according to the present invention can be seen in Figure 1. The pipe connection is formed by a


    male piece -1-and a female piece -2-. Both the male part -1-and the female part -2 are hollow to give way to the fluids of the connected pipes. In the case shown, the pipes or tubes (not shown) would be joined by interference in both the male part -1-and the female part -2-. To ensure the fixing of the tubes to said male part -1-and female part -2-, these have radial projections of a truncated conical shape -13-. The figure also shows one of the buttons -31-of the retention device, whose function is to retain the male part -1-inside the female part -2-, the buttons 31 must be operated to extract the male -1 -.
    Different internal elements of the connection can be seen in Figure 2. The hollow spaces -19-, -29-of the male part -1- and the female part -2- can be observed, respectively. A retaining ring of interior elements not shown -9- can also be observed internally. A main function of the interior elements is to seal the joint between male part -1-and female part -2-. The figure also shows the pins -3- of the retention device of the male part that collaborate to retain a radial projection -11-of the male part -1-. The retention occurs because the radial projection -11-comes into interference with projections corresponding to the pin -3-. Said projection has a ramp shape -34- for the entrance of the male part -1-, generally wedge shaped. This form allows the radial projection to enter -11-, but prevents its exit due to the existence of dimensional interference, as shown in Figure 3.
    The entrance ramp -34- of one of the pieces can be observed, in perspective in figure 3. The button -31- corresponding to one of the pieces can also be observed.
    The three pieces -3-, -4-, -5-belong to the retention device and its operation (see figures 3 to 6). In the embodiment shown, said parts are arranged inserted in the female part -2-. The pins -3-, -4-and -5-are arranged in a triangular shape.
    In the male part -1-the radial projection -11-, conical projections -13 and a stop -12- can be observed. The pipe or pipe would be pressurized on the tapered projections -13 to the stop -12-as shown in Figure 7.
    While the invention has been described with respect to examples of preferred embodiments, these should not be construed as limiting the invention, which will be defined by the broader interpretation of the following claims.
