Definitions

  • the present invention generally relates to an end fitting assembly for mounting a cable to a bracket.
  • bracket which is coupled to a vehicle.
  • the bracket has a plate member defining an open-ended slot.
  • the end fitting assembly is received vertically into the top of the open-ended slot at the plate edge.
  • the bracket has a projection or upset that extends from a planar side surface of the bracket near the bottom of the slot.
  • Conventional end fitting assemblies are provided with a collar that moves axially along an axis of the conventional end fitting assembly. The collar moves between an engaged position in which the upset is received inside the collar. The collar receives the upset to prevent the conventional end fitting assembly from being removed from the open-ended slot. The collar is moved axially from the engaged position to a disengaged position to allow the conventional end fitting assembly to be inserted into or removed from the open-ended slot.
  • the collar is slid or threadedly rotated into its engaged position, and may be biased towards its engaged position by a compression spring disposed between the collar and a retaining cap fixed to the conduit housing.
  • a compression spring disposed between the collar and a retaining cap fixed to the conduit housing.
  • An end fitting assembly secures a cable to a bracket.
  • the bracket defines an open-ended slot and has a retention tab.
  • the end fitting assembly is included in a motion transmitting remote control assembly.
  • the motion transmitting remote control assembly includes the cable, which comprises a conduit and a core wire.
  • the end fitting assembly includes a body configured to receive the cable.
  • the body defines a channel for receiving the bracket to allow the body to be inserted into the open-ended slot of the bracket.
  • the end fitting assembly also includes a flexible latch having a base portion coupled to the body.
  • the flexible latch also has a finger portion extending from the base portion.
  • the finger portion has a generally hook-shaped configuration.
  • the flexible latch is movable between a disengaged position and an engaged position for engaging the retention tab of the bracket to secure the body and the cable within the body to the bracket.
  • the body defines a cavity adjacent the flexible latch.
  • the finger portion is housed within the cavity when in the disengaged position for allowing the body to be inserted into the open-ended slot of the bracket.
  • the finger portion is rotatable from the disengaged position within the cavity to the engaged position to engage the retention tab of the bracket for securing the body within the open-ended slot of the bracket. Therefore, the end fitting assembly is automatically coupled to the bracket via the engagement of the finger portion of the flexible latch and the retention tab of the bracket. Coupling the end fitting assembly to the bracket prevents the end fitting assembly, and therefore the cable that is received by the body, from moving relative to the bracket.

  • an end fitting assembly is generally shown at 10.
  • the end fitting assembly 10 is included in a motion transmitting remote control assembly.
  • the motion transmitting remote control assembly includes a cable 12, such as a transmission cable of a vehicle.
  • the motion transmitting remote control assembly mounts the cable 12 to a bracket 14 that is coupled to the vehicle.
  • the bracket 14 has at least one plate member 16 defining an open-ended slot 18.
  • the end fitting assembly 10 is disposed within the open-ended slot 18 of the bracket 14 for coupling the end fitting assembly 10 to the bracket 14. Said differently, the end fitting assembly 10 is seated within the open-ended slot 18.
  • the open-ended slot 18 of the bracket 14 has a U-shaped configuration, which is complementary to the end fitting assembly 10.
  • the open-ended slot 18 can be of any suitable configuration.
  • the bracket 14 includes a retention tab 20 extending from the plate member 16 of the bracket 14.
  • the retention tab 20 is typically adjacent the open- ended slot 18 of the bracket 14. More typically, the retention tab 20 is located below the open-ended slot 18 of the bracket 14.
  • the retention tab 20 has a shoulder surface 22 that extends perpendicularly from the plate member 16 of the bracket 14.
  • the retention tab 20 also has a ramped surface 24 intersecting the shoulder surface 22.
  • the ramped surface 24 is disposed proximate the open-ended slot 18 and the shoulder surface 22 is distal the open-ended slot 18 relative to the ramped surface 24.
  • the end fitting assembly 10 engages the retention tab 20 of the bracket 14 to couple the end fitting assembly 10 to the bracket 14. More specifically, the end fitting assembly 10 engages the shoulder surface 22 of the retention tab 20. The engagement of the end fitting assembly 10 with the retention tab 20 is described in greater detail below.
  • the cable 12 comprises a conduit 26 and a core wire 28 disposed thought the conduit 26.
  • the conduit 26 of the cable 12 is coupled to the end fitting assembly 10 by disposing the conduit 26 through the end fitting assembly 10.
  • the cable 12 is mounted to the bracket 14 once the end fitting assembly 10 is coupled to the bracket 14.
  • coupling the end fitting assembly 10 to the bracket 14 secures the conduit 26, and therefore the core wire 28, to the bracket 14.
  • Mounting the conduit 26 to the bracket 14 prevents the cable 12 from moving relative to the bracket 14 while allowing the core wire 28 to move within the conduit 26 of the cable 12.
  • the end fitting assembly 10 includes a body 30 configured to receive the cable 12. More specifically, the body 30 defines a hollow core 32 for receiving the conduit 26 of the cable 12. The body 30 has a first end 34 and a second end 36 spaced from the first end 34 with the hollow core 32 of the body 30 extending along an axis A therebetween. Generally, the conduit 26 of the cable 12 is disposed within the hollow core 32 and extends beyond the first end 34 and the second end 36 of the body 30. It is to be appreciated that the conduit 26 may have multiple component or may be a single unitary component.
  • body 30 may have a tapered wall 37 defining a portion of the hollow core 32 between the first end 34 and the second end 36 of the body 30, as shown in figure 6.
  • the tapered wall 37 allows the cable 12 to pivot at the second end 36 of the body 30.
  • the tapered wall 37 allows pivotal movement of the cable 12 at the second end 36 of the body 30 while the cable 12 at the first end 34 of the body 30 is prevented from pivoting.
  • the body 30 may include a bearing wall 39 within the hollow core 32, as shown in Figure 6, for securing the conduit 26 within the body 30 of the end fitting assembly 10.
  • the body 30 may have a first half 30A and a second half 30B removable from the first half 30 A for allowing access to the hollow core 32 to insert the cable 12 within the hollow core 32.
  • the first half 30 A and the second half 30B are separated from each other and the conduit 26 of the cable 12 is disposed within the hollow core 32 of the first half 30A of the body 30.
  • the second half 30B of the body 30 is then coupled to the first half 30A for trapping the conduit 26 of the cable 12 within the hollow core 32 of the body 30.
  • the conduit 26 may be coupled to the body 30 of the end fitting assembly 10 in any suitable manner, such as press-fitting the conduit 26 into the hollow core 32 of the body 30. Coupling the conduit 26 to the body 30 of the end fitting assembly 10 prevents the conduit 26 from undergoing longitudinal and lateral movement relative to the end fitting assembly 10.

  • the channel 42 of the body 30 has a diameter D2 that is smaller than the diameter Dl of the body 30 adjacent the channel 42. Said differently, the channel 42 is recessed relative to the rest of the body 30 of the end fitting assembly 10.
  • the diameter D2 of the channel 42 is also approximately equal to or less than the width W of the open-ended slot 18 for allowing the plate member 16 of the bracket 14 to be received by the body 30 to seat the body 30 in the open-ended slot 18 of the bracket 14. Said differently, once the plate member 16 is inserted into the channel 42 of the body 30, the diameter Dl of the body 30 on either side of the plate member 16 is larger than the width W of the open- ended slot 18 to prevent the body 30 from being pulled through the open-ended slot 18. Seating the body 30 in the open-ended slot 18 of the bracket 14 prevents the body 30, and therefore the conduit 26 coupled thereto, from moving laterally relative to the bracket 14.
