IDEA NOTE Fix harness with magnets

Harness holder is attracted to the magnets. The attraction force can be adjusted by changing the distance the magnet is screwed-in.

IDEA NOTE Notch the base plate to prevent rotation.

To prevent the guide plunger shaft from rotating, the tip is roughly guided by a notch in the base plate.

    CAD Data Limitations

    1. Assembly data shows the assembly drawings in the concept design phase. The sole purpose of the data is to explain the structure and functionality of the assembly and is not considered nor to be used as a final design.
      You will need to edit the Data so that it meets your specific design conditions.
    2. Unit assembly Data consists of some sub-assemblies.
      It is configured so that each sub-assembly unit can be used as it is or edited.
    3. * The part in the frame is a sub-assembly unit.

    4. The Data for fabricated parts is based on easy-to-edit dimensions and shapes in sketches and histories.
    5. The Data including the third-part components are made by the Company.

Application Overview

Purpose

  • Guide plunger retains the PC board. Magnets attract the lid to hold the harness for soldering.

    Wire harness: A bundle of wires.

Points for use

  • Manual mechanism with a guide plunger retains the PC board.

Target workpiece

  • PC board unit
    Dims.: 10 x 20 x 1.2, Harness DIA. φ2.7

Design Specifications

Operating Conditions or Design Requirements

  • External dims: W110 x D70 x H34
  • Guide plunger stroke: 6mm
  • Harness holder rotation: 90°
  • Harness holder is retained by magnets.

Required Performance

  • Workpiece retention force: 1.24N
  • Harness clamp force: 7.8N

Selection Criteria for Main Components

  • Guide plunger
    • In order to obtain clamping force that does not damage workpieces, plunger for light loads is selected.
  • Magnet
    • Select magnets that can hold the harness and be adjusted manually.

Design Evaluation

Verification of main components

  • Verify if the guide plunger can retain the workpiece.
  •  Spring load
    • Formula: Reaction force: F 1 =kx 1 +S
    • Initial load: S = 0.6N
    • Assumed deflection during pressurization: x 1 =2mm
    • Spring constant: k = F 2 /x 2 =1.9/6=0.32 N/mm
      When (Stroke (x 2 )6mm,(Max - Min load) = F2 = 2.5 - 0.6 = 1.9
      =2.5-0.6=1.9Load increase of N: From catalog)
    • Assumed applied load on workpiece: F 1 =kx 1 +S=0.32×2+0.6=1.24 N

Other Design Consideration

  • A guide plunger with clamp from the side is selected since the top surface of the PC board is the working surface.
  • The harness is held with a hinge to keep the assembly simple and easy to adjust.
  • The harness holder is made of stainless steel 403 to ensure it is magnetic.
  • The clamp block tip has a 5° angle to push the piece diagonally down.
  • The magnets are held with set screws.(Can also be glued)
