D-Sub Connector Insert Arragenments


There are a number of pages that deal with D Sub-miniature connectors on the engineering web site. The main two are Manufacturers of Commercial D-Sub Connectors, and Manufacturers of Military D-Sub Connectors. Military connectors meet the MIL-DTL-24308 specification.

A graphic of a D-Subminiature outline, and a table of D-Sub mechanical dimensions is provided to determine the different sizes available. Along with a new page providing Insert Arrangements for D-sub connectors.

9-pin D-Sub Insert Arrangements,
15-pin D-Sub Insert Arrangements, Size 22 Contacts.
15-pin D-Sub Insert Arrangements, Size 20 Contacts.
25-pin D-Sub Insert Arrangements,
26-pin D-Sub Insert Arrangements,
37-pin D-Sub Insert Arrangements,
44-pin D-Sub Insert Arrangements,
50-pin D-Sub Insert Arrangements,
62-pin D-Sub Insert Arrangements,
78-pin D-Sub Insert Arrangements,
104-pin D-Sub Insert Arrangements.

So the Insert Arrangements for D-subs gives the dimensions and locations of the individual pins, while the Dimensional outline for D-subs gives the case out-line. In addition, you can determine the pin location or pin numbering using the 'insert arrangement' pages.

Although in declining usage on PC's the three most common sizes used are the 9-pin [Serial Port], the 15-pin [Video Port], and the 25-pin [Parallel Port].

IC Socket Drawings


Added a few more pages off the IC Package Definitions page.

SOP IC and Socket graphic,
BGA IC Graphic,
IC DIP Sockets graphic,

and I think one other. These are new pages to hold a graphic or picture file, with little or no text on the topic.

IC Package Drawings


The IC Package Type Definitions page received a few new links to new pages. Some of the links were already there but pointed to a pic file, now they point to a new page that contains the gif file.


The first three are Integrated Circuit packages, while the last two are really passive component packages. In any case the new pages provide a drawing to show what the package looks like.

Definition of Capacitor Terms


There are now thirteen pages that cover the Capactior Dictionary section. Each page now has a link to all the other pages at the top of the page. In addition a few new graphics were added to aid in the defintion of the terms.


Because this section is a dictionary of Capacitor Terms not all letters are covered, but two new pages were added:
The first new page covers 'G' terms; Dictionary of Capacitor Terms, 'G'.
While the second page covers 'P' terms; Dictionary of Capacitor Terms, 'P'.
And another page for 'D' Capacitor definitions.

The definitions came from pages all ready in the section but those pages were runing a bit long. How ever because of other additions made tonight, now other pages are running to long which means that they may be sub-divided into other 'new' pages.

The dictionary pages change more than a few times a year, as more terms are added or new graphics are added, and in some cases obsolete terms are removed.

Some of the 'side' terms are still not listed in the Capacitor section, but they may be found in the Glossary of Engineering Terms section.

Note; 1/28/2010. The links to the capacitor dictionary have been updated in a newer blog posting; Indexed URLs.
