摘要:
A device (1) for connecting together tubes (101, 102) for protecting an optical fiber cable (103), the device comprising a tubular body (2) defining a channel (3) having a first housing (4.1) and a second housing (4.2) each arranged to receive one of the tubes and provided with means (5) for sealed retention of said tube, and an annular step (9) extending between the housings to form an abutment against penetration of the tubes into the housings, an annular sealing element (10) being arranged in the first housing beside a flank of the step and being arranged to be taken, under the effect of axial compression exerted by the tube, from a first state in which the sealing element defines a section through which the cable can pass freely to a second state in which the sealing element defines a section less than a section of the cable. A segment, of an optical transmission circuit including such a connection device.

Connection elements include a coupling defining an internal channel having an end segment possessing an insertion opening for insertion of an endpiece and provided with members for retaining the endpiece in leaktight manner therein. The members include an annular axially compressible sealing element that is mounted in the coupling to have one face serving as a bearing surface for a terminal face of the endpiece, and an annularly-shaped retaining element elastically deformable in a radial direction that is received in an inner groove (21) of the end segment to have an inner circumferential portion projecting through an opening of the inner groove so as to be received in an outer groove of the endpiece. The inner groove has a concave frustoconical flank beside the opening of the end segment to form members for shrinking the retaining element, and a convex frustoconical flank on its side remote from the opening.

An instantaneous connection device includes a tubular body (1), a tight element used to hold the end of a line in the body and includes an elastically deformable annular sealing element and a holding element that are arranged to receive the end of the line, a cam member for moving the holding element from a free state into a state wherein it grips the end of the line when it is axially displaced in the tubular body from a first position to a second position, and an elastic member for bringing the holding element back towards its second position. The sealing element is mounted between a radial shoulder of the body and a radial face of the holding element. The radial shoulder and the radial face are provided with reciprocal reliefs for laterally coming into contact with the annular sealing element.

Device for connecting a tube to a circuit element, including a cartridge type tubular body provided externally with a washer for anchoring the body in a well of the circuit element and provided internally with a retainer for the tube, characterized in that the anchor washer is mounted on an end portion of the tubular body designed to lie at the level of the opening of the well when the connecting device is in use, the end portion being elastically deformable between a deformed state enabling the washer to be placed on the body and a rest state for retaining the washer on the body.
摘要:
A coupling device comprising a tubular body defining a channel and axially subdivided into an anchor section provided on the outside with an anchor member associated with a cover mounted on the body to have both an actuator end for actuating the anchor member and a drive end, and so as to be movable between an inactivation position and an activation position, a resilient return member urging the cover towards the activation position being mounted in a chamber defined by the cover and the body, the cover having a holder device for holding it in the inactivation position, which holder device is arranged to be declutchable when the cover is moved into a declutching position beyond its inactivation position in a direction away from the activation position, and the device including a passage for putting the chamber into communication with the well.
摘要:
A quick-coupling tube fitting for coupling a tube to a body having a bore. The fitting includes a retaining member received within the bore for retaining the tube, and a release member received within the bore to be slidably moveable to release the retaining member when pushed. The release member has a rear portion that projects outwardly from the body. The rear portion has a shoulder surface which faces a stationary surface of the body to define a groove therebetween in which a safety member is disposed to delimit the sliding of the release member. The safety member is provided in the form of an elongate member which is closable to form a ring in the groove.
摘要:
Device for coupling the ends of carrier tubes used for guiding and protecting a cable. The device includes axially juxtaposed first and second tubular bodies, each having a first end for connection to one of the tube ends and a second end for connecting the body portions and which coaxially receives a flexible tubular sealing member. The bodies are connected such that they are relatively movable between a first position in which the body bodies are close together and the sealing member is in a rest state, and a second position in which the bodies are spaced apart and in which surfaces thereof contact the sealing member to dispose it into an energized state wherein it is urged radially inward and has an inner diameter that is no greater than the outside diameter of the cable.
摘要:
The invention relates to a coupling device comprising a tubular body (100) having a plastics material portion provided with an anchor member (5) for anchoring the tubular body in a first duct, the anchor member being made of metal. The anchor member is secured to a metal support element (1) that is covered at least in part in a layer of plastics material (9) compatible with the plastics material of said tubular body portion and that is connected to said portion by local welding of said portion with said layer. The invention also provides a method of fabricating such a coupling.
