Re: Better drawing of the intended target.

[Mark Anderson <emer@xxxxxxxx>]

Sorry I could not make it this morning, everyone. I had a class that I am dropping in the 10am slot, so I should be able to make the 10am's from now on.

As a quick reminder, the connector meeting is Tomorrow at 10AM.

UPAMD,

 

Following the meeting this morning, Tom has forwarded a mechanical drawing of the target for our use.

 

This has the dimensions.  It also shows the concave conical section for the top of the contact pad as we talked about. Input from vendors suggests that this may want to be flat.  Apple uses a shape similar to that drawn.  Input from the group  with respect to these features is welcome.

 

The committee needs to specify what the target connector is. The connector on the cable needs to have spring pins to contact the target and meet the retaining features.  It is expected that different connector vendor for the spring pin, Pogo pin, male portion of the connector will used different pin and spring mechanisms.

 

In addition to the target shape, we need to specify the required minimum and maximum spring force for each contact and the release forces for the latching mechanism.

 

This version of the connector has the creapage enhancing features that allows the power pins to be moved closer together and still retain the 63V creapage distance.   This is about as small as it can get.  This is slightly shorter than the models on the website.

 

The conn.pdf shows the design concept for the cable connector and its latching mechanism.  This will be modified with different pin lengths to stage the connect sequence of negative/positive/communications pins and the inverse disconnect sequence.

 

 

Please review and comment.

 

Respectfully;
