Abstract
A non-metallic fluid coupling is disclosed with electrical current transferring elements incorporated therein. The coupling is formed of two C-shaped halves of non-metal, non-conducting material, where each halve includes integral hinges and latches, or hinges and latches made of a common material with the C-shaped halves. A non-metallic, substantially rigid sealing sleeve can be incorporated into the coupling to seal the coupling while maintaining the strength of the coupling.
Claims8
A fluid coupling for joining first and second fluid pipes each having a ferrule adapter at respective mating ends, the coupling comprising:
- first and second semi-cylindrical elements cooperating to form a cylindrical coupling, the first and second semi-cylindrical elements formed of a non-metallic material, said first and second semi-cylindrical elements each having integrally formed thereon complementary interlocking hinge elements for establishing a pivoting relative motion of the first and second semi-cylindrical elements;
- a pin passing through the first and second hinge elements;
- a latch releasably connecting the first and second semi-cylindrical elements;
- and
- a non-metallic sealing sleeve positioned adjacent the ferrule adapter of each fluid pipe to seal the coupling;
- wherein a first latch element of the latch is integrally formed with the first semi-cylindrical element and comprises a pair of barbed projections extending from the first semi-cylindrical element over a shoulder integrally formed on the second semi-cylindrical element;
- and
- wherein a second latch element of the latch is integrally formed with the second semi-cylindrical element and comprises a single barbed projection extending therefrom and passing between the pair of barbed projections on the first latch element to engage an integrally formed member of the first latch element.
