Parametric Multiconnect Cutout Negative (Bản tuỳ biến rãnh âm Multiconnect)

This is a parametric implementation of the multiconnect “connector back” negative, i.e. it's a customizable model of the female channel on the back of multiconnect-mounted designs. The negative is used by boolean subtracting it from the back of your own parts, “cutting” the necessary channel.

A number of sample negatives are provided, but most likely you want to customize your own with the instructions below.

Configuring your own negative

1. Visit the Onshape document here. You should see the 3D part in the center and some panels surrounding it.
2. Locate the “Configurations” area in the top right.
   • You may have to expand the panel down to see all the configuration options.
3. Adjust the configuration options/variables as needed, see the section below for details.
   • Regular Onshape controls can be used to manipulate the model, or navigation buttons in the bottom toolbar can be used.
4. Export the model with the export (download) button in the bottom toolbar.

Configuration Options

Height: The height of the negative, top to bottom.

Repeat Indent: Repeats the inner indent down the part. This indent (which is a bump once the negative is applied) “locks” a connector in place, so this option is used for parts mounted with more than one connector.

Indent Spacing: The spacing between the repeated indents, in 25mm units.

Quick Change Cutouts: Enables cutouts in the channel to slot in a connector in mid-way, rather than sliding it entirely from top to bottom. To be used by parts mounted with more than one connector, follows the indent spacing option.

Quick Change Offset: The offset of the quick change cutouts relative to the indents.

The design and option limits are generally in-place to prevent non-functional parts, though the document can always be copied and modified if you find them too restrictive.
