Added a new page to define Gender Changers. The page is linked off one of the Dictionary of Engineering Terms pages, and off the Manufacturers of D-Sub Connectors page. I'll start to add companies that manufacturer gender changers as I find them.
The graphic is an adapter and not a gender changer. D-sub is short hand for D-Subminiature.
Related pages:
Dsub Shell Dimensions.
Dsub Insert Arrangements.
Mil-C-24308 Connector Manufacturers.
IDC D-sub Shell Dimensions.
Pin/Plug D-sub Shell Dimensions.
9-pin Dsub Insert Arrangement.
25-pin Dsub Insert Arrangements.
An Insert Arrangement is another way to indicate a connector pin out. Insert Arrangements indicate the pin numbering of a connector but does not indicate what signal may be on a pin. The term Signal Assignment is used to define a particular pin with an electrical signal. Signal Assignments for any number of interface buses may be found on the Personal Computer Buses page.
It's a bit early in the day, the virus scanner is running, my server is off-line, and I just can't figure out what to say ~ so I'll have to get back to it and fix it later.
Two more pages were added dealing with D-Sub miniature connectors, both linked off the main Insert Arrangements page. The new pages provides connector dimensions for Insulation Displacement D-Sub connectors, and D-Sub connectors with Plug Pin Contacts.
D Subminiature connectors are not found on commercial PCs any longer but are still being used in Industrial and Military applications. There are many other connector styles that are smaller and able to carrier higher speed signals.
Any way now there are pages that provide shell sizes for;
Board Mount D-Sub Connectors,
Insulation Displacement D-Sub Connectors,
Solder Cup D-Sub Connectors.
With each page providing Mechanical Dimensions for each of the connector styles, and showing the different connector sizes [number of pins] available under each different style.
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].
A related page, general listing of Manufacturers of Military Grade Connectors.
A few new pages have been added over the last week. Tonight I pushed the listing of Manufacturers of Header Connectors onto its own page. The link reside on the main page for Manufacturers of Connectors.
Also off the dictionary section, 'P' Engineering Terms, a new page was added to cover the term, Pulse Shape. and related terms to describe a waveform.
And in the same dictionary section, 'S' Engineering Terms, another new term was added to hold a larger graphic of a Synchro. Same pic that was on the previous page, but a bit larger.
Added a page to cover IDC Connectors. Another page addition to the Engineering Dictionary.
IDC [Insulation Displacement Connectors] work with Flat and Twisted-flat ribbon cables and offer cable to connector connections with out soldering.
Manufacturers of Connectors.
Manufacturers of Ribbon Cables.
The diagram is an example of an IEEE-488 IDC connector.
Added another page to cover the definition for a Banana Jack style connector. One page shows a graphic for a female to male banana jack connector, while a second page provides a view of a female to female banana jack connector. Both styles provide a BNC connector at one end. Both pages are linked off the main Engineering Dictionary page.
A definition for Twisted Pair cable was also added to the Engineering Glossary section. Of course there are pictures for each new page. Think RS422..
A definition for the term Back Shell was added, again off the electronic dictionary section. The end section of a connector shell....
Related links include; manufacturers of Connectors, and manufacturers of Cables.
A new page was added to hold a graphic for a Bayonet style locking connector. The page is linked off the page covering the definition of a BNC Connector. A small definition is also provided. Both pages are part of the Definition of Radar Terms section.
Also added a graphic holding page to cover the definition of Terminal Lugs. The Terminal Lugs diagrams reside in the Engineering Glossary of Terms section.
In addition to the pictures referenced above a few others were added to pre-existing pages. A few additional entries were also added to the Definition of Resistor Terms section, but no new pages added.
I also moved the Balun Definition to its own page as the definition was being duplicated on three other pages. The new page covering Baluns is linked from a number of pages including the Antenna Terms section, and Engineering Dictionary section. Of course each of the new pages have been added to the site-map, linked of the index page.
Finally added some text to the Sealed Circular Connector page located on interfacebus.net. The page was created a few months back... So far the page is a collection of links to pages that list manufacturers that produce round connectors on interfacebus.com.
The listing groups all the different pages into one list, which should make round connectors easier to locate.
Looks like the web site could use a few more pages dealing with Military Spec connectors.
Several pages have been added to hold military CID [Commercial Interface Document] paper mechanical drawings for the IEEE-488 connector, GPIB [General Purpose Interface Connector].
The main link is off the top level HPIB Description page, to IEEE488 CID Mechanical Drawings. Here are the new pages, that carry the CID drawings:
A-A-55094,
A-A-55138,
A-A-55139,
A-A-55140,
A-A-55141,
A-A-55144,
A-A-55145,
A-A-55146.
These page show the mechanical drawing for the connector, and provide no other data other than the specification title. The purpose of the page is to hold the connector picture or gif and that's it.
The page addition to the site map is coming soon.
I added a new page that contains the definition of a Twinax connector. Remember it's a new page and contains little data. The link is off the RF Radar Terms section.
Remember because so many sites relay on hits from search engines, adding pages may not help a web site. A new page may place well in a search for some terms but because it takes three months to get a page rank may not place well for many terms ~ which is why they get up-loaded as the page is generated.
Even as new pages are added and older pages are up-dated, site hits are down this week. Page visits are down at least 300 per day this week, looks like about 7,800 visits per day ~not page views. It must be common when so many sites depend on search engine traffic. Regardless of what you do the search engine may bring in less traffic. I think interfacebus.com takes in 75% of its traffic from search engines. A small reduction in search engine traffic results in a major drop of visitors. I see it all the time........
Also up-dated the manufacturers of Connector Dust caps page.
Added a new page that depicts coaxial impedance terminators. The link is off one of the Glossary/Dictionary pages. Just now, clicking on the thumb nail brings up a larger pic of the image, but I may end up adding a new page to hold the larger image.
The new page show both a BNC terminator and a TNC terminator [or dummy load].
Twenty eight other files were up-dated today, but most of those were for new java code for Google Analytics. However a few pages did receive a small formatting correction, a word was put in bold text to follow the formatting of all the other pages. Oh, I did make sure that I added the new java code to the top six pages that receive the most hits per day ~ but it's just a maintenance issue. The new java code had been out for awhile now, but I'm really already in the middle of another update.....
I added two pages to cover the mechanical standards for the VME interface. The first page covers the new mechanical specification that deals with the VPX card format; REDI, Ruggedized Enhanced Design Implementation Form Factors. While the second page addresses the original VME form function, IEEE-1011.
The IEEE1101 page was added just for completeness and currently only points to a mechanical drawing of the VME board sizes that have been on the site for a number of years now.
The REDI standard defines the new direction with the VME bus, using the VPX card. The VME road map is moving in a new direction leaving the old legacy form factors behind.
COTS Manufacturers:
..... Manufacturers of VME Boards.
..... Manufacturers of VPX Boards.
..... Manufacturers of VXS Boards.
I added a page that describes MIL-STD-1399 specification. The page provides Alternating Current, Electrical Power Types. The addition of the MIL1399 page compliments the Naval Use Environmental standard; MIL-HDBK-217 page.
The Military Standard 1399 page details the three types of electrical power supplied on Navy ships; Type I, Type II, and Type III.
Other Military specifications and Handbooks may be found on the Military Specifications page.
Because of a typo this blog post was updated on 3/1/2011.

Following yesterdays addition of the listing for microSD connector manufacturers, two additional pages to cover miniSD connector manufacturers and of course Secure Digital connector manufacturers were added.
At the same time I added the microSD and miniSD links to the alphabetic interface bus listing.
From the data shown in the attached graphic it does not appear that a listing of computer buses in alphabetic order is required or at least used that much. I assume designers find the required bus by function, type, or name.
So the series of pages were started last Feb. but only receive about 10 or 20 hits a-day, with a total pageview count of 3,869 for the year.
In regards to the Mirco-Secure Digital 'microSD' page, a listings was started that provides microSD connector manufacturer. This new listing is linked off the microSD Description page.
microSD is the smallest of the Secure Digital family of products. The microSD card format is one of many 'thumb' drive flash formats. microSD happens to be the smallest form factor
I added a new page to cover the insert arrangements for MIL 83513 connectors. The following link provides MIL83513 Pin locations. It's linked off the main MIL-DTL-83513 page that was added a while ago, but never updated. I did add a few words to the MIL-DTL-83513 page tonight, but just in passing, it's off the Military Connector specification page. I also added a page that covers MIL-83513 insert arrangements. I noticed that the MIL-DTL-32139 is out-of-date. Both of these Mil standard pages were just copies of the MIL D-sub manufacturers page, at MIL-C-24308. So I updated MIL32139 and added a page for part numbers and insert arrangemets.
Here is the listing of the main page for Manufacturers of Military Connectors. And the main page of Manufacturers of Connectors.
