The sleeve and/or the collar are made of electrically conductive plastic material to electrically connect the tubes.

Description

Coupling device for releasably connecting two tubes.

The invention relates to a coupling device for releasably connecting two tubes each having a free end. The invention relates more particularly to a double-hull coupling device intended to be placed in an aircraft. Multiple coupling devices are known for connecting the free end of two tubes, in particular tubes carrying fluids, such as those comprising a sleeve and a collar, and in which: the sleeve has an axis of elongation and has an inner surface defining a cavity for receiving the free end of the two tubes, - said collar comprises a first shell and a second shell, a hinge device and a locking device, - the first hull and the second hull each have a first end and a second end, and the hinge device connects the first end of the first shell to the first end of the second shell, - the first shell and the second shell of the collar are movable relative to one another. to the other between: - an open position of the collar in which the second end of the first hull and the second end the second shell provide a space between them, and - a closed position of the collar in which the collar surrounds the sleeve to hold the two tubes together, - the locking device has a locked state and a state unlocked, in the locked state the locking device now releasably maintaining the second end of the first shell and the second end of the second shell in the closed position of the collar. For safety reasons, especially when the transported fluid is flammable, it is important to ensure electrical continuity between the two tubes to dissipate electrostatic charges and thus to avoid the creation of a spark potential difference. Usually, this electrical continuity is achieved by means of an electrical conductor extending in the direction of the axis of elongation and whose establishment on the collar is sometimes tedious and therefore expensive. The invention aims to reduce the manufacturing cost of the coupling device, but also the induced costs it generates, in particular by facilitating its use and improving its robustness. To do this, according to the invention, the coupling device 1 o is at least partly made of electrically conductive plastic material, in order to electrically connect the two tubes. Thus, it dispenses with electrical conductor since the function is performed by the collar and / or the sheath, thus reducing the number of parts and the cost of manufacture. On the other hand, the plastic has an elasticity and a coefficient of friction which makes it possible to create a contact with a slight stress between the parts which reduces the uncertainty as to the flow of current between the parts in contact without generating a significant friction between them. Finally, the plastic has a low density to reduce the weight of the coupling device and therefore its cost in the operation of the aircraft. According to another characteristic according to the invention, preferably the coupling device further comprises two seals intended to be interposed between the sheath and the free end of each of the tubes, the seals are made of Elastomeric material 25 electrically conductive, and the sheath is made of electrically conductive plastic material. Thus, the electrical conduction between the two tubes performed by the coupling device is improved. According to a complementary feature according to the invention, preferably the coupling device further comprises two tips of electrically conductive material and intended to form the free end of said tubes, said seals being arranged (sealing ) between the sheath and said end pieces. According to another complementary feature according to the invention, preferably the sheath has a rib extending perpendicularly to the elongation axis of the sheath and projecting relative to the inner surface of the sheath. It has been found that the sheath is subjected to stresses that can generate by fatigue cracking of the sheath when the sheath is made of plastic material, and that the above solution makes it possible to solve this problem effectively. According to another characteristic according to the invention, the sheath preferably has an outer surface having a generally circular shape perpendicular to the elongation axis of the sheath, said sheath is provided with indentations on said outer surface, and the collar comprises in addition a stop cooperating with the indentations of the sheath to prevent the rotation of said sheath about its axis of elongation relative to the collar, when the collar is in the closed position. Thus, it is simply and effectively avoided that the collar starts to rotate relative to the sheath (in particular under the effect of vibrations and movements of the tubes causing the sheath, in particular by friction due to the joints), and therefore to the tubes. around the axis of elongation, which risks bringing the coupling device into a position where it risks creating a technical problem (contact with a moving or short-circuited part by contact with an electrically conductive part, by example) or be difficult to handle. According to a complementary characteristic according to the invention, preferably the first shell carries a first flexible tab whose free end bears against the indentations and prevents the rotation of the sleeve relative to the collar around the axis of elongation in a first direction, and the second shell carries a second flexible tab whose free end bears against the indentations and prevents the rotation of the sleeve relative to the collar about the axis of elongation in a second direction, opposite said auditory first sense. According to another characteristic according to the invention, the first shell and the second shell are preferably made of electrically conductive plastic material. This further reduces the weight of the coupling device and increases its electrical conductivity. According to yet another characteristic according to the invention, the electrically conductive plastics material preferably includes metal particles. This solution is simple, inexpensive and effective in giving the plastic a level of electrical conductivity sufficient to prevent the creation of a spark by electrostatic discharge. According to another complementary feature, the electrically conductive plastic material is preferably polyamide with inclusion of metal particles. The polyamide has a satisfactory compromise to obtain a mechanical strength and sufficient electrical conductivity without generating a very high cost. According to another characteristic according to the invention, the first shell and the second shell are preferably strictly identical. The number of molds necessary for producing the coupling device is thus reduced, which reduces the cost of producing the coupling device. According to the invention, the coupling device preferably also has the following characteristics: the coupling device further comprises a safety device comprising a first support fixed on the first shell, a second support fixed on the second shell and an articulated hook on the first support between an active position and an inactive position, the first support of the safety device is identical to the second support of the safety device, the first support of the safety device and the second support. of the safety device each have a recess, - the hook comprises: - a base pivotally mounted in the recess of the first support of the safety device, - a bulge engaging by elastic deformation in the recess of the second support of the safety device, only when the hook is in the active position, to hold the clamp e n closed position. 1 o The number of different parts is thus further reduced, which reduces the cost of producing the coupling device. According to a complementary feature according to the invention, preferably the first support of the safety device is obtained from material with (integrated to) the first shell and the second support of the safety device is obtained from material with (integrated to) the second hull. The number of parts constituting the coupling device is reduced, which reduces the number of assembly operations. According to another complementary feature according to the invention, preferably the locking device has a locked state and an unlocked state, and the locking device prevents the safety device from being in the active position when the locking device is in unlocked position.
