  • One or more fasteners may be used to secure a first component to a second component.
  • a first fastener such as a mid-panel nut
  • a second fastener such as a screw or nut
  • the mid-panel nut is a kind of a self aligning fastener and is used to mount one panel (child panel) to another (mother panel).
  • the mid-panel nut is inserted into a cut-out/slot formed in the mother panel at one station, for instance, in an assembly line.
  • the mother panel bearing the mid-panel nut is moved to a subsequent station where the child panel is mounted to the mother panel at the mid-panel nut using a threaded fastener, such as a screw or a bolt.
  • Mid-panel nuts generally, are made of metal, and include a head and a body part having two or more arms.
  • the arms of the mid-panel nut move away from the threaded fastener due to force applied by the threaded fastener onto the arms of the mid-panel nut.
  • the threaded fastener When the threaded fastener is fully inserted into the mid-panel nut, the threaded fastener does not engage with the arms of the mid- panel nut. Instead, the threaded fastener only makes contact with the arms of the mid-panel nut.
  • the threaded fastener does not provide any support to the arms when the threaded fastener is inserted into the mid-panel nut.
  • the insertion force required for deploying the mid-panel nut in the mother panel is considerably high since the mid-panel nut is made of metal. For instance, a force of 70 kilogram-force (kgf) or more may be required to insert the mid-panel nut into a slot formed in the mother panel. Also, the body of the mid-panel nut may cause damage to the mother component if inserted at such high force. Further, manufacturing of the mid-panel nut needs to go through multiple processes, (at least two) to be formed.
  • the mother panel can be a carrier of a vehicle and may be made of sheet metal.
  • vibrations may occur due to metal-metal contact between the mother panel and the mid-panel nut.
  • the vibrations may cause the metallic mid-panel nut and the sheet metal of the mother panel to cause noise, thereby adversely affecting the NVFI (noise, vibration, harshness) characteristics of the vehicle.
  • NVFI noise, vibration, harshness
  • the metal sheet of the mother component can be exposed, for example, to elements of nature which may cause damage to the metal, for instance, by rusting.
  • fasteners such as the mid-panel nuts
  • such fasteners have been designed to be formed of plastic instead of metal, so as to address the issues associated with the metallic fastener elucidated above.
  • a plastic fastener may be unable to withstand the forces involved in coupling the panels. For instance, since the threaded fastener does not provide any support to the arms of the mid-panel nut, the components to be secured by the mid-panel nut may get displaced easily if a considerable amount of force is applied.
  • the arms of the mid-panel nut may break down if force is applied over a period of time.
  • the fastener is designed with plastic material to have the required strength, the size of the fastener may be very large and may require further modification in the mother component and child component design to be able to be accommodated.
  • the mid-panel nut is made of plastic material and may be used for securing components, such as for coupling an instrument panel trim and a carrier of a vehicle. Since the mid panel nut is made of plastic, the manufacturing process is simple, cost-effective, and consumes less time. Further, the mid-panel nut, according to the present subject matter, has considerably low insertion force and still can be used to securely mount a child component to a mother component. Moreover, the mid panel nut can be used with mother components made of sheet metal, without any issued regarding NVFI especially in vehicles.
  • the mid panel nut is designed to withstand the loads of the components mounted using the mid-panel nut without undergoing failure.
  • the mid-panel nut includes a body having a nose (in the direction of insertion of the mid-panel nut into a mother component) and a head opposite to the nose.
  • the head may be formed at one longitudinal end of the body.
  • the mid-panel nut further has a hole formed in the head for the insertion of the threaded fastener for engaging the threaded fastener with the mid-panel nut.
  • the body of the mid-panel nut may include 4 or more walls.
  • the mid-panel nut may include two flexible snaps formed on opposite walls of the body.
  • the flexible snaps are designed in a way that they can flex when the mid-panel nut is inserted into a slot in the mother component, thereby reducing the insertion force required for deployment of the mid-panel nut.

  • the threaded fastener when assembled with the mid-panel nut, makes a positive engagement with the interior of the flexible snaps, as a result of which, the flexible snaps are non-yielding in the assembled state (i.e., when the mid-panel nut is assembled with the threaded fastener).
  • the flexible snaps do not flex inwards even when a considerable amount of force is applied, thereby ensuring that the mid-panel nut securely sits in the mother component and does not inadvertently disengage from the mother component.
