As can be understood from the explanation, these are: 15 Figures 1a and 1b show the disassembled parts of two tubular fittings containing a female element conforming to the invention. It shows the images separately; Figure 2 shows a cross-section of the head of a female element conforming to the invention; Figures 3a and 3b show a female element, 20, conforming to the first application mode of Figure 1a. cross-sectional images separately in the unattached and attached positions. It shows; Figures 4a and 4b show an unattached female element, suitable for the second application mode of Figure 1b. and shows them separately in cross-section in connected positions. DETAILED DESCRIPTION OF THE INVENTION Figures 1a and 1b show two versions of a tubular fitting containing a fitting head (3) conforming to the invention. This tubular fitting consists of a female element (1) and a male element, both of which are tubular. (7) includes. These elements form the end pieces of the pipes (not shown). Male element (7), 30 The female element (1) will be penetrated and inside it will connect the two pipes in a fluid sense. It is designed to be held. Two elements (1,7) hold a fluid whose cross-section is advantageously circular. It defines the passage, but of course, a different cross-sectional shape can also be imagined. Based on the figures, the female element (1) has a main axis (AA') and a main 35 defining an insertion direction. The main body (2) includes a connecting end (2a) and a connecting end (2a) that continues the connecting end (2a). It includes a tubular section (2b). In Figure 1a, this tubular section is straight along the same line as the major axis (AA'). 4 In Figure 1b, the tubular section (2b) is angled, i.e., a first section is on the extension of the main axis (AA'). It is arranged and a second part adjacent to the first, in another direction, here perpendicular to the main axis (AA'). It is arranged in one direction. The straight or angled shape of the tubular part (2b) of the main body (2) of the fitting. the layout plan of the system into which it will be integrated, and in particular the pipes to be connected to that system It will depend on the relative arrangement. 5 The end of the male element (7) is connected to the main body end (2a) to fit into the tubular part (2b). will pass through it and thus connect the male element (7) to the female element (1) in a fluid sense. It is designed in this way. For this purpose, the inner diameter of the tubular part (2b) of the main body (2) is the male element (7) It is largely equal to the outer diameter. In the examples shown, the inner dimension of the connection end (2a) is the tubular 10 the inner diameter of part (2b) is larger than the main body (2), which is composed of two parts (2a, 2b) It has at least one inner shoulder (2c) in the connection between them. However, this particular configuration is entirely It is optional, as the connection end (2a) can have the same dimensions as the inner diameter of the tubular part (2b). The female element (1) also contains a fitting head (3). This head is attached to the connection end (2a) of the main body (2). It is designed to connect and surround it at least partially. Fitting head (3), main 15 by means of any means suitable for the body (2), e.g. the fitting head (3) of the main body mounted by passing it over, or conversely, by passing the main body (2) over the fitting head (3). It can be fitted. The fitting head (3) forms a connecting piece independent of the main body (2). Male This housing (2) is connected to element (7) to ensure a leak-proof connection. This feature is particularly important. It is interesting because, as explained in the introduction to this application, it is a 20 that can be attached to a wide variety of mainframes. It allows you to provide a connecting piece. In the configuration shown in Figure 1a, the main body (2) is diametrically on the outer wall of the main body (2). It contains two opposing locking protrusions (2d) (only one of these protrusions is visible in Figure 1a). This lock The protrusions are designed to fit into two openings (3c) in the fitting head (3). These openings (3c) fit the fitting 25 It is arranged on flexible tongues defined by (3) longitudinal cuts on its head. In the configuration shown in Figure 1b, the main body (2) is located on the outer wall of the main body (2). It includes four key projections (2d) distributed at an angle of 90° to each other (two projections (2d) in Figure 1b) (visible). Similarly, four openings (3c) are arranged on the fitting head (3). This application 30 In this mode, the connection end (2a) of the main body (2) runs along two transverse orthogonal axes. It is symmetrical and this situation means that the fitting head (3) has four relative parts that are 90° apart from each other. This feature allows the main body (2) to be fitted onto the connection end (2a) in its angular orientation. one of the four different directions of the tubular part (2b) (at a distance of 90°) or the other By positioning the fitting head (3), it ensures that the female element (1) is seated in the fitting 35 It becomes usable in a wide variety of system configurations where it is intended to be integrated. For example, the locking protrusions (2d) are on the connection head (3) and the openings (3c) are on the connection end Of course, other assembly methods besides those shown could be provided by providing (2a). Returning to the general description of a female element (1), the fitting head (3) is one that can be clearly seen in Figure 2. It includes an internal guide ring (3a). This internal guide ring (3a) is used to restrict the passage from its circumferential end. It extends radially into the head (3). This restriction is in the fitting head (3) for the male element (7), Here, it defines a passage that is circular. Therefore, this passage is where the fitting head (3) is mounted to this main body. When done, it looks at the tubular part (2b) of the main body (2). The diameter of this passage is the outer part of the male element (7). It is largely equal to the diameter. As can be clearly seen from the figures, the inner guide ring (3a) is male When element (7) is inserted into the female element (1) to be connected, the end of this element (7) is connected to the main 10 It offers a preferably angled cheek to guide it toward the body (2) (in the direction of insertion). This The inclined cheek extends from the inner surface of the coupling head (3) to the circumferential end of the inner guide ring (3a). and when the male element (7) is inserted into the female element (1) into this ring, this element (7) sequentially oriented so that the cone section passes through the large base and then through the small base, It essentially gives a truncated conical shape. However, the inner guide ring (3a) is 15 from the inner surface of the fitting head (3). It can also extend radially at 90°, and the presence of an oblique cheek is by no means necessary. The fitting head (3) and inner guide ring (3a) are produced, for example, by plastic injection molding. It can be a single, monolithic piece. To ensure the connection is leak-proof, the fitting head (3) is circumferential to the inner guide ring (3a). It includes a flexible seal (4) integrated with its end. This seal (4) is defined by the main body (2). Extending at least partially into the passage, the inner guide ring (3a) is directed toward the male element (7) It partially blocks the passage. When the insertion end of the male element (7) is inserted into the main body (2), The flexible seal (4) is deformed by this male element (7). 25 The flexible seal (4), which is advantageous, is an annular seal in which at least one lip extends radially. It consists of parts (to fit the outer dimensions of the male element (7)). Flexible seal (4), male The end of element (7) can be deformed when positioned on the tubular part (2b) of the female element (1), It is made of an elastomeric material that makes it flexible. This is because the end of the male element (7) is connected to the female 30 When positioned on the tubular part (2b) of the element (1), it passes through the inner guide ring. The male element can be lifted by the tip of the (7) and the male element has a sealed contact cheek. This applies to lips that can be pressed down correctly. Flexible seal (4) fits into the inner guide ring (3a) of the fitting head (3), e.g. circumferential 35 of this ring (3a). The end is securely fastened by arranging it in an annular recess of the flexible seal (4). For this purpose, the circumferential end of the inner guide ring (3a) is designed to improve the grip of the flexible seal (4) 6 It can be configured. This configuration may correspond to at least one protrusion (3f) or at least one cavity. In the example shown, the circumferential end of the inner guide ring (3a) has a triangular cross-section and the seal (4) carries a protrusion (3f) occupying its ring housing. The configuration in question is the inner guide ring. by providing a large contact surface between the flexible seal (4) and the connection, ensuring a robust and compact connection. It provides. 5 This assembly is injected onto the inner guide ring (3a) of the fitting head (3) of the flexible seal (4). by molding the flexible seal (4) onto the guide ring (3a) or by making the two It can be produced by injection molding. This joint form is particularly protruding (3f) above the inner guide ring (3a). When found, a secure connection is made between the flexible seal (4) and the rest of the connection head (3) 10 This ensures that the inner guide ring (3) and flexible seal (4) are formed as a single unit. It is a fitting head that houses the flexible seal (4) in the following way (3). This configuration allows the fitting head (3) to hold the flexible seal (4) to ensure that it is transported and / or handled without the risk of loss during the process It is particularly advantageous in this respect. Elastomeric material in a mold that defines the shape of the gasket (4) and includes the fitting head (3). The injection takes place at one or more injection sites. An injection site is... an injection that defines the part, an injection mark, a gap, or a pico on the surface of the part It tends to mark the point. Injection to ensure the connection is leak-proof. region / regions such that the lip of the flexible seal (4) will not be on a contact flank 20 is selected. Therefore, when the flexible seal (4) contains several lips, the lip of the flexible seal (4) is selected. The contact cheek and each contact cheek bear no signs of injection. In the special configurations shown in the figures, the guide ring (3a) is positioned between its circumferential end and the fitting head. (3) between an inner surface, into which the connecting end (2a) of the main body (2) can be inserted (25 in Figure 2). It also defines a groove (3b) that is clearly visible. When this end has a circular shape, the groove (3b), It is ring-shaped as shown in the figures. The connecting end of the main body (2) is grooved (2a) (3b) When inserted, the inner shoulder (2c) and the inner guide ring (3a) of the main body (2) are in contact with each other. They are not. The distance between them defines a groove (6). The groove (6) is connected to the end (2a). two 30 defined by a defined base and guide ring (3a) and the inner shoulder (2c) of the main body (2). It has a separate side wall. This groove (6) connects the female element (1) and the male element (7). It is designed to include the flexible gasket (4) used to make it leakproof. The flexible seal (4) consists of two lips (4a, 4b) here. In the absence of the male element (7), there is a groove (6) The outer lip (4a) is arranged and an inner lip (4b) is radially inserted into the main body (2) at least 35 By extending partially, it partially blocks the passage by the guide ring (3a). 7 Two lips (4a, 4b) are used to define a flexible seal (4) with an H-shaped cross-section, for example a The central standing can be joined. In this configuration, the flexible seal (4) is in the concentric rings. It consists of two arranged lips (4a, 4b) and the rings are connected to each other via the central foot. The outer lip (4a) is squeezed into the groove (6) when the connecting end (2a) is inserted into the head (3). On the other hand, the inner lip (4b) is deformed by the male element (7) and the male element (7) is the main 5 When inserted into the connection end (2a) of the body (2), it is pushed back into the groove (6). This configuration is shown in Figure Shown in 3b. The outer lip (4b) is a guide ring to facilitate the insertion of the male element (7). This element (7) has an inclined contact cheek like (3). Since this inner lip (4b) is flexible, During their attachment, the male element must be given (7) to advance into the female element. It has very little effect on the insertion force. The two lips close off two possible leakage lines and 10 It makes the connection perfectly leakproof. In the locked configuration shown in Figure 4b. The inner lip has a cheek that makes a watertight contact with the male element, and the outer lip has a groove. (6) a cheek that makes leak-proof contact with the inner wall of the connecting end (2a) forming the base. It has. As is advantageous, the fitting head (3) must have at least one locking groove (3d) (two in the example shown in the figures). It has (number). This groove is configured to accommodate a locking pin (7a) of the male element (7). It is done. When the male element (7) is properly inserted into the female element, the inner guide 20 It may have a bracelet (7b) configured to rest on the ring (3a). This bracelet is beveled It may be and may have a complementary shape to that of the inner guide ring (3a). To secure this position, the tubular connector shown in the figures attaches to the two side arms of the head (3). U 25 is designed to pass through the side openings (3e) provided on it by sitting down as if riding a horse. It includes a clip (5) in the form of two openings. These two openings face each other. The two side arms of the clip (5) are the male element. (7) passes into the fixing grooves on the outer wall. Of course, the female element (1) fixes the male element (7). It could also be fitted with a tool other than the clip (5). One particularly advantageous feature, shown in Figure 1b but easily incorporated into Figure 1a, is 30. According to the female element (1), it includes an assembly indicator (8). Here this indicator is a protruding pin. It takes the form of a flat, rectangular tongue that overlaps with (8a). On one of its faces, the pin (8a) The tongue opposite the bearing face bears an advantageous so-called "locking" pattern. This pattern It can be a colorful pattern, and any color makes it particularly visible in its surroundings. The pattern, It can be a simple block of solid color, or it can consist of a color gradient. Some configurations have 35 interlocking pattern, one or two-dimensional barcode (e.g. QR code, data matrix code, PDF417, It contains a code such as AZTEK etc. In any case, the locking pattern is the female of the male element (7). 8 a sighting device to ensure that the element is mounted correctly It can be interpreted by the machine and / or by an operator. The indicator (8) is placed on one of the lock bearings (3d) of the fitting head (3) which is shaped for this purpose. It is designed to fit. The connection end (2a) of the main body (2) and the head (3) are connected to this connection end (3a) 5 When properly seated, it has a flat surface (2e) facing the lock groove (3d). The symmetry and the main body (2) and the head (3) mentioned in the paragraph are in several different relative angular orientations. In order to maintain the sitting ability, the main application mode shown in Figure 1b that its body (2) has four flat surfaces (2e) placed between two consecutive notches (2d) Attention should be paid. 10 In practice and before inserting the male element (7) into the fitting head (3), the indicator (8) of the fitting head (3) is placed into one of the locking grooves (3d), this head forms the female element (1) of the main body. (2) surrounds the connection end (2a). When the male element (7) is inserted (to align the lock pin (7a) with the lock groove (3d) correctly (directed), this pin (7a) rests on the tab (8a) of the indicator (8) groove of the indicator (8). (3d) slides into and possibly onto the flat surface (2e) of the main body (2). This sliding locking pattern during movement, e.g. at least part of the indicator (8) on the flat surface (2e) It gradually becomes visible when positioned on it. Alternatively, the locking pattern can be set to 20 To make the indicator (8) visible without moving it completely over this flat surface (8e), A window can be provided on the fitting head (3), near the flat surface (2e). In any case, male When element (7) is inserted into female element (1) by holding this element (1) against the indicator (8), locking It is sufficiently displaced by the locking pin (7a) to make its pattern visible and detectable. Of course, the invention is not limited to the methods described and the invention defined by the claims 25 Alternative structures can be used without deviating from the scope.
