According to another embodiment, shown in
figure 28 , on each male (21) and female body (31) there are provided a plurality of reliefs (2191), and the surface of the clamping cone facing the corresponding male (or female) body is provided, in corresponding positions, with invitations (2391) configured to allow said reliefs (2191) to enter by means of axial movement.

- The space (314) in which the tongues are introduced is arranged at the elastically deformable portion of the piece on which there are provided the clamping teeth, and the high tongues (383), while entering this space, deform elastically outwards this deformable portion, widening the clamping teeth. Obviously, there are provided as many spaces (314) and respective deformable portions of the female body (31) as are the positions where the clamping teeth are provided.
- In order to carry out the coupling of male and female in block position, after inserting the two elements into each other until the respective clamping teeth are engaged, it is needed to translate the ring (38) so that the low tongues (381) are introduced without interference in the space (314) of the female body (31) and the projecting tooth (382) of the ring goes in the block position, shown in
figure 3 , thus avoiding the possibility that the ring slides axially. In such a way it is guaranteed the coupling of the four inner teethed sectors, avoiding at the same time that the two male/female bodies are removed. The unblocking operation is allowed only by inserting the tip of a common tool (as for example a screwdriver) in the space corresponding to the position of the tooth. The tool makes the ring (38) roto-translate which, by virtue of the geometry of the elements, translates axially and goes again in the initial rest condition. - The decoupling step of the two co-molded male/female bodies occurs by translating onward the ring (in
fig. 27 it is represented the starting position of such step): the insertion with interference of the high tongues (383) in the respective space (314) of the female body causes the displacement outwards of the flexible tongue (320) of the female body (31) on which there are provided the clamping teeth (317). In such way, the inner teeth of the female body are decoupled from the outer ones arranged on the male body, thus allowing two bodies to be decoupled by simple traction. - It is to be observed that the ring (38) acts on the female body by means of axial translation, and in fact it does not have even a thread in its geometry.
Claims (5)
- Sealed, multipolar connector (1), comprising:- a male sub-assembly (2) comprising a plurality of pins (27),- a female sub-assembly (3) comprising a plurality of sockets (37),
wherein said pins are configured so that they engage said sockets when the connector is closed, and wherein- said male sub-assembly (2) comprises a co-molded element (21) in plastic and rubber,- said female sub-assembly (3) comprises a co-molded element (31) in plastic and rubber, and a locking ring (38),- said co-molded elements (21, 31) comprise, in a plurality of circumferential positions, clamping teeth (217, 317) configured to be engaged with each other when said elements (21, 31) are coupled,Characterized in that the clamping teeth of said female sub-assembly(317) are positioned on elastically deformable tongues and are configured so that the clamping teeth (217, 317) are engaged when said elastically deformable tongues are in rest position,in that said ring (38) is provided with tongues (383) configured to be introduced with interference in a respective space (314) provided on the female body (31),said tongues (383) being configured to widen said clamping teeth (317) while entering said respective space (314)so that the clamping teeth (317) of the female element do not engage the respective clamping teeth (217) provided on said male connector,and in that said ring (38) can rotate with respect to said female sub assembly between a first position, in which by axially sliding said ring (38) said tongues (383) can be introduced in said respective space (314) and a second position, in which the axial sliding is hindered by a suitable block element (382). - Sealed, multipolar connector (1), according to claim 1, characterized in that said male sub-assembly (2) further comprises:- a plug (22),- a clamping cone (23),- a big seal (24) of the clamping cone (23),- a small seal (25) of the clamping cone (23),- a stop nut (26),and in that said female sub-assembly (3) further comprises:- a plug (32),- a clamping cone (33),- a big seal (34) of the clamping cone (33),- a small seal (35) of the clamping cone (33),- a stop nut (26).
- Sealed, multipolar connector (1) according to claim 2, characterized in that said female co-molded element (31) comprises a plastic portion (311) bonded to a co-molded seal (312), configured to exert sealing both between the female sub-assembly (3) and the male sub-assembly (2), when assembled, and between the co-molded element (31) and the clamping cone (33), and said male co-molded element (21) comprises a plastic portion (211) bonded to a co-molded seal (212), configured to exert sealing both between the male sub-assembly (2) and the female sub-assembly (3), and between the co-molded element (21) and the clamping cone (23) .
- Sealed, multipolar connector (1) according to claim 3, characterized in that the shape of the co-molded element (31) of the female connector comprises, in the portion coupling with the male, an outer cylinder (315), an empty circular crown, apt to house the male element, and an inner cylinder (316) in which there are obtained both the housing holes of the sockets (37) and a central shaped hole (39), configured to house a respective shaped projection (29) provided on the male body (21), and in that said clamping teeth (317) are positioned on the inner side of said outer cylinder (315) and are configured so that the portion of the plastic body supporting them is flexible (320), and can be elastically deformed outwards to allow the connector to be decoupled.
- Sealed, multipolar connector (1) according to claim 4, characterized in that each clamping cone (23, 33) is coupled with the respective co-molded male/female portion (21, 31) by means of a snap-system, which can be actuated by a simple axial translation of the clamping cone,in that each clamping cone (23, 33) comprises a couple of pliers (231, 331), diametrically opposed to each other,and in that on each male (21) and female (31) body it is provided a wedge element (219, 319), configured so that when the respective clamping cone (23, 33) is assembled in the body (21, 31), the wedge (219, 319) widens the respective pliers (231, 331), which closes then by grasping the wedge element and thus guaranteeing that the cone is coupled with the respective co-molded body.
