FAQ

I am looking for a very specific center pin DC coaxial connector for my laptop power cord. I have an Alienware M17xR3, I know it is probably a LONG, very LONG shot that i find one online, but $3 is better than the $130 it is to replace it. I don' t have the proper caliper to determine the actual size, but based off a ruler.70-.80mm Outer diameter .50-.60mm Inner Diameter

wtf just find one or a charger on OKorder

i have a 1995 ford ranger 2.3l and i cant find the self-test connector can anybody help??

Right side if steering column, below dash. It is a 16 pin connector and the body of it is trapazoidal in shape.

Hi ,I have recently bought a Philips HTS 3105 Home theater system which works great.But I am unable to find an FM antenna with the correct 'connector' for my system.It's outer dia is same as that of the normal TV coaxial RF connector , and the center pin has a hole in it.Sorry for being crude, but i don't know what is the connector's name Pls. help.Thanks in advance.

It's called a push-on F connector. However, unless you are connecting it to your cable system, all you need is a single strand of wire that you can shove into the center hole. The best is a 24 guage or thinner wire, about 3 feet long, with a loose knot in it that forms a crude loop. I've even put a twist-tie in there and it worked as an FM antenna. If you are going to connect it to a coaxial cable, you will need an adapter. Normally, these come with the system, but if not, it's a Radio Shack item.

I recently purchased an NZXT Apollo computer case which came with a 4-pin power led connector. However, I found that there were no instructions in the motherboard/case manuals of where to insert the connector in the motherboard(I own an Asus P5Q SE/R Intel ATX motherboard).I did some research, but most people seem to have 2 or 3 pin connectors.

check ur motherboard manual it should have it in there

I don't get it my antec 900 case has these odd 10 pin usb plugs that have a white plastic thing covering one pin so it might be 9 pin and I don't know were they plug in!!! I only have the case so far to my build and want to buy the best mobo but I need to know if those go under onboard usbs or what.

computer fan is 12 volt as mentioned formerly get off to ya interior reach maplins. as for usb fan, the only style u could desire to get is a computer fan. usb is 500m amps. as for the amp, does it have a warmth sink? or a place on the pcb for yet another fan?

I purchased 1/2 fmc conduit, 1/2 bushings, 1/2 knockout junction box, and 1/2 connectors.The conduit, bushings and knockout seem to fit, but the connector looks too small? What size connector should I be using with 1/2 fmc? Or is there a trick to connecting it?

Have you tried assembling the connector to the conduit? If you spin the collar off, you should have 3 pieces. The outer collar, a plastic ring, and the end piece that screws into the conduit. Slide the collar and ring over the end of the conduit and screw the end piece in until the conduit end is covered by the end piece. If it doesn't fit, the store sold you the wrong connector. Hope this helps

how many 3 pin connactors and molex and that sort does this mobo have and will it support 3 120mm fans and 1 200mm fan like my case has 2 default 120 mm fans and i want to install 1 more 120mm fan and 1 200mm fan will it be possible?

For big fans that draws relatively large amounts of current (compared to smaller fans), you really should connect them to the PSU molex connectors using adapters. The motherboard fan headers can't handle much current, and larger fans WILL burn them out. Don't ask me how I know.

Assume you start with a 12 inch piece of 16guage stranded automotive wire for each connector test.You then check continuity and resistance for the wire.Then you cut the 12 inch piece of wire in half and try reconnecting one end of each wire with following methods.1) Soldered ends together2) male/female spade connector3) ring terminal bolt ring terminal4) twisted ends together w/ twist capThen you check continuity and resistance for each different type of connector.How can you tell if you have connected the two wires properly? i.e. soldered correctly, or crimped the spade connectors snug enough, or twisted the ends properly or tight enough?How do you do this with a multimeter?

It sounds as though you're trying to measure the difference between the various types of connections. Is that right? One difficulty is that multimeters, unless they're laboratory-grade, aren't very accurate at measuring very low resistance values. I don't think you'll get any meaningful results doing continuity and resistance measurements. An accurate way to determine the resistance in a connection is to measure the voltage drop across the connection. To do this, you'll have to connect a power supply and a resistive load in series with the connection. You'll also need an ammeter so you can tell how much current is flowing through the circuit. Set your multimeter for volts, and place one probe on each side of the connection. The voltage reading represents the amount of voltage lost through the junction. With the voltage and current measurements, you can use Ohm's Law to calculate the resistance in the connection. However, if you find a resistance, there's no easy way to tell whether it's due to an error in making the connection, or an inherent loss in the type of connection itself. Probably the only way is to repeat the test several times for each connector type, discarding any results that are significantly different from the average. Given that all of these connection types are used very commonly in car or home wiring, I don't think you'll find much of a significant difference in each of them in terms of resistance. There are other factors that make each of them a good or bad choice in various wiring situations.
