View Patent ↗A collar for maintaining electric cables is disclosed. The maintaining collar includes an annular sleeve which may be crossed by the electric cables and having two axial ends around which protective sheaths of the electric cables are intended to be mounted; an annular attachment flange capable of being attached on a fixed support, the attachment flange being maintained axially around the sleeve and capable of pivoting around the sleeve; and a seal between the maintaining collar and the support on which the seal is intended to be attached.
1. A maintaining collar for maintaining electric cables, the collar comprising:
an annular sleeve which may be crossed by electric cables and having two axial ends around which protective sheaths of the electric cables are intended to be mounted;
an annular attachment flange capable of being attached onto a fixed support, the attachment flange being axially maintained around the sleeve and capable of pivoting around the sleeve; and
a seal between the maintaining collar and the support on which the maintaining collar is intended to be attached,
wherein the attachment flange includes a central opening, and the sleeve includes a first annular shoulder portion which passes through the central opening of the attachment flange such that the attachment flange is capable of pivoting around the sleeve,
wherein the sleeve includes a second annular shoulder portion with an outer circumferential surface which abuts an inner circumferential surface of the support,
wherein the seal is an annular seal gasket housed in a groove formed in the second shoulder portion of the sleeve, and
wherein the attachment flange is maintained axially around the first shoulder portion of the sleeve between a flank of the sleeve and an axial retaining ring housed in a groove in the first shoulder portion of the sleeve, the flank of the sleeve extending radially and connecting the first shoulder portion of the sleeve and the second shoulder portion of the sleeve.
2. The maintaining collar according to claim 1 , wherein the seal is an annular seal gasket housed in a groove formed at an outer periphery of the sleeve.
3. The maintaining collar according to claim 1 , wherein the attachment flange is maintained axially around the sleeve between a flank of the sleeve and an axial retaining ring housed in a groove of the sleeve.
4. The maintaining collar according to claim 1 , wherein the attachment flange is a metal plate provided with bores for letting through fixing screws.
5. The maintaining collar according to claim 4 , wherein the bores are regularly spaced apart over a whole circumference of the attachment flange.
6. The maintaining collar according to claim 1 , wherein each of the axial ends of the sleeve comprises means for maintaining protective sheaths of the electric cables.
7. The maintaining collar according to claim 1 , wherein said collar is axisymmetrical.
