Hi,
Does anyone know which schematic symbol and footprint to use for cellphone usb charger (female) connector – the connector which is inside the body of the phone itself. I was planning to make my pcb mobile phone charger powered.
Thanks and Regards,
Arvind Gupta.
Well you might need to give more details here. There is no standard usb connector. (From the view of the pcb designer. The connection between the connector and the cable plug is standardized.)
So first find a component that you can buy, and then look up what the landing pattern for this component should be. (Datasheet) You can also look at the footprints found in Connectors_USB. Maybe one of them is available to you. (And fits your application.)
As symbol, look in the Conn (or Connector for nightly) lib. Here it mostly depends if you want to use USB 2 or 3.
Thanks for your reply. As I understand, all mobile phone chargers nowadays have the same miniature usb connectors for charging (I am not referring to the broad USB 3.0 connector in the phone or old mobile phone chargers). I am looking for its female connector version so that the PCB can use any generic mobile charger for power. Since I will not use the connector for data transfer, USB 2 /3 may not matter here. Basically I am looking for the female connector of the male connector circled in the attached picture pls. I just dont know its name.
Thanks again,
Arvind Gupta
You need either Micro A or Micro AB receptable
Which one do you want? (None of them will be compatible on the PCB side. This is why you need to make this decision before you go further)
Yes. I am looking for the Micro B receptacle (preferably with horizontal orientation & through hole anchors in the PCB). Which symbol and footprint do you suggest pls? If not available in Ki CAD, what keywords should I search the net with for the symbol and footprint pls?
Thank You.
Arvind Gupta
Again you do not seem to understand me.
Searching for a footprint first is the wrong direction.
YOU NEED TO SELECT A PART FIRST!
And then you search for a footprint for this specific part. (most likely you will need to design it yourself.)
THERE IS NO GENERIC FOOTPRINT THAT WORKS FOR ALL USB CONNECTORS.
Above i already told you that the symbols that exist in the official lib are found in the Conn lib. The footprints are in Connectors_USB. If nothing in these two libs fits a part that is available to you, You need to design them yourself.
Specifically, you need to choose a part which is well anchored to the PCB so that it can withstand the mechanical stresses of being repeatedly plugged and unplugged. Some I see only have solder tabs for surface mount. Others I see have 2 or 4 tangs going through the board. You need to look at these and make a decision on which suits your particular needs based on price and availability.

OK.I just realized that I cannot use mobile phone USB chargers (I will need 6 v input; not provided by mobile phone chargers). Also I want to avoid components not available on KiCAD library as they may not be commonly available.
So the problem comes down to which cheap, easily available 6v (AC to DC voltage) adapter with male pin – female pin combination do you suggest. I just need a DC power supply with 0.6-1 A current rating. I can search RS/ebay but I don’t know which ones are commonly available (I will first try the local markets before ordering online). This is absolutely the first time I am working with power supply connectors.
I just realized it is more difficult to select connectors than ICs! And thanks all for your continued support.
Arvind Gupta.
First, to answer your original question: the footprints for USB connectors are here. So there are several different Micro B USB receptacles there. You could choose one of those parts, if you didn’t want to create your own footprint.
There’s not necessarily any correlation between those two things. The KiCad library contains things which people felt like contributing to the KiCad library. These might be common or not-so-common. And certainly plenty of commonly available parts will not be in the KiCad library yet.
For that, you will probably want a barrel jack.
OK thanks. I wanted to know if there are ready made symbols and subsequently footprints for these two components I am planning to buy (in case any one has come across them earlier):
SPDT Switch (Part No: SS12D00G3 )
Thanks and Regards,
Arvind Gupta
PS. Which is the library for SPDT switches and oscillators. KiCAD library would have at least basic SPDTs and 4 pin oscillators defined (I could not find it though 
). That way I can get going with the schematic at least. If required, I can start a new discussion on this topic. – Thanks. AG.
look in my molex lib
both part/symbol and footprint
I checked the molex folder. It most probably has components related to barrel connector. I had already got the the symbol and footprint of barrel connector in KICAD library. I am looking for the symbol and footprint of the mini SPDT switch and 4 pin oscillator as per the links posted last time.
Thanks for your time,
Arvind Gupta
Ok
there are other libs i have apart from Molex
Abracon lib keep some oscillators and there are an SPDT somewhere also in there.
just need to guesstimate the Manufacturer lib
CK-Components:PTS530GG065SMTR
a small smd push-button
Thanks. The Oscillators are all SMD type in Abracon. The link shows a through pin device (I will be using these devices for the first time; so SMD may be difficult for me to solder) Also, I am looking for sliding SPDT components; not push buttons. Any other library you suppose I should check out pls. (I dont have the dimensions of these devices; otherwise would have made the components myself 
). Have written to the sellers on the site; they are looking for the drawings.
Regards,
Arvind Gupta
So you would simply trust somebody else that they made the footprint correct without any chance of checking them?
I avoid trough hole components as much as possible
not producible for volume, and typically takes up huge space, and mess up the secondary layer.
so i my libs are a bad source for trough hole
sorry
OK. I got the dimensions of the SPDT switch. I was trying to make its schematic symbol through quicklib website. I made the following symbol:
I wanted to know how to hide the text in blue (1, Pole, 2) I was able to hide the name of the component but not the remaining text.
Also, is there any similar website tool to make the corresponding footprint pls. Quickink is a great site.
Thanks,
Arvind Gupta
In the symbol settings.
(top toolbar the button that looks like a gear)
untick the “shop pin name” selector.
By the way your symbol looks like some sort of resistor with a middle connection.
OK thanks. I will try that out. Well … that was what quicklib was offering… and I will take it as it requires lesser time and effort. Also, any similar sites for quickly making footprints of the switch ?
Regards,
Arvind Gupta
