Your opinion on the feasibility of a video clip

Simulation Resistance of materials
1

Hello

You are probably familiar with the clip system that is on the attachment.
Not mastering the hardness of plastics, I have trouble knowing if the male part will fit in the female part or if I have to rethink the model?
Thank you.

Hello

    Looking at the drawing, the answer is: it depends:(

  It depends on the material, the polymers are a lot of them with lots of different characteristics.

 At first glance I would say that for an ABS type material, it would need more elasticity in the orifice (make the rectangle longer to give it elasticity).

If your polymer is a foam or an elastomer it should fit....

If you work with SolidWorks you can do a clipping simulation and that would be the best.

Quickly a simulation with ABS: (Re<<400 MPa) with a view of areas above 100MPa

Edit: all in all, I'm going to go through a system with screws...

;)

Whaaa... :)

As stated, I'm going to go through a screw system.
But you make me discover a great function.
In fact, I'm working on fusion 360 (I'm actually starting...).
I don't think he's the equivalent there.
This function would interest me but I'm afraid I won't have the time to learn all these tools...

Could someone tell me what this kind of tab is called please?

Hello BJ07

I don't want to quibble about flexible lugs, but here are three remarks (although you seem to have chosen another method of attachment (a screw))

  1. As you made the square hole (in the woman ;-)  ) the so-called male part will not fit, because the rectangular hole must be larger than the ergo. In other words, the hole is 2mm while the lug is 2.5.
     
  2. In addition, there must be a gap between the max size of the ergo and the hole for the lug to bend before clicking.
     
  3. There is a specialized feature in SolidWorks for making lugs and other snap-together methods.

 

A friendly note to our colleague @Maldoror00

You don't need to have the female part to do the ergo simulation. Simply place your efforts on the chamfer with a single fixed connector on the top of the ergo. Side connectors are useless.

In addition, in the female part, you have an artificial concentration of stress in the corners only because there is no play between the lug and the die. If you were to make a simulation of the forces on the matrix separately, you should have a first concentration distributed on the edge.

Otherwise I completely agree on the dimensions of the lug which are not good.
What apparently does not know @BJ07 is that once the lug is clipped, the forces are only made in traction.
So if, as you suggest, (make the rectangle longer to give it elasticity), you have to specify that on a thickness of 2mm for plastic it's very soft. And that the height is generally defined according to the rigidity of the assembly. Easily dismantled or not. If you want to be unremovable, then you make a very short lug.

Although the design is badly rated, if we take the ratio of height to width of the lug, we must not be far from what is needed. On the other hand, the 0.5 heel won't hold anything at all. ETC...Etc... But the subject is closed since finally the requester changes his mind for a screw.

Hello@BJ07

You have these functions in SolidWorks with the fastening functions.

How to get there

  1. Tools
  2. Commands
  3. Fixing function
  4.  

Here you will find the Stud and lug housing functions.

Kind regards

Hello Zozo_mp,

Yes, indeed, I had some pretensions about my male part compared to the female part... You can't make up for it... :)

I'm really new to the design of this kind of object and even more so to software manipulation.

For the sake of economy and for its simplicity, I chose Fusion 360.
I think it would take me a long time to learn how to handle and understand all the functions you mentioned.
I have to have with my financial means and above all... intellectuals... :)

As I progress, I discover constraints due to my inexperience. My screw system might be suitable.
I'm still keeping the idea of snapping around (thanks for the title), I'm going to look for slt of this type of part.

Hello BJ07

As you posted in "Other Products" I didn't pay attention to the fact that you had "Fusion 360" and not SolidWorks. It is quite likely that the functions I told you about will also be in your software.

If the answers suit you, you can close the subject.

Kind regards
