Problems solved by technology

For metallic conduits and non-metallic terminals (e.g., plastic), compression-based connections may be less useful because the compression required to sustain a steady pull force may exceed the structural limits of non-metallic terminals

Embodiment Construction

[0015] In the following description, numerous specific details are set forth in order to provide a more thorough description of the invention. It will be apparent, however, to one skilled in the art that the present embodiments may be practiced without these specific details. In other instances, well-known features have not been described in detail in order not to obscure the invention.

[0016] Adapters are provided for attaching flexible conduits. Adapters secure flexible conduit with conduit retention clamps. Due to the geometry of the flexible conduit and the arrangement of the clamps, the conduit retaining clamp axially constrains the flexible conduit to the fitting without unduly compressing the fitting.

[0017] figure 1 An example of a flexible conduit 95 , depicted here as a flexible metal conduit 95 (FMC), is shown. The FMC 95 may also be known as Greenfield or Flex, and may be made of aluminum, steel, galvanized steel, or other materials. Other types of flexibl...

Abstract

Systems and methods are provided for attaching a flexible conduit to a fitting. Prongs (84) of a conduit retention clip (85) are configured to be arranged at opposite sides of the flexible conduit (95) in an aperture (83) of the fitting. By aligning the prongs (84) in grooves of the flexible conduit (95), the flexible conduit (95) is held in place in the aperture of the fitting without sufficientcompression to surpass the structural limits of the fitting.

Description

technical field [0001] Embodiments generally relate to fittings for flexible conduits. Background technique [0002] Flexible conduits can be made by coiling self-interlocking ribbed strips of material. The interlocking ribbed structure forms a tube that can be bent or flexed in multiple directions. The ability to bend allows flexible catheters to be used in many applications where rigid catheters may not be practical. Unlike rigid conduit, flexible conduit can change its shape to match each installation, or as repairs are made. The wire is pulled through the tube, and thus the wire is protected by the conduit from both internal and external damage. [0003] Flexible conduits may be attached to one or more terminals or connection boxes. The fitting between the flexible conduit and the terminal needs to be strong enough to withstand a steady pull so that the flexible conduit cannot be removed by bending or flexing. For metal-on-metal connections, strap-based or compressi...
