Im possibly thick, but not sure yet (electrical things)

So finally getting my self around a maplin that has all the bits i want, i get an inline fuse holder and a fuse and some wires.

Just came home, and realise: i am not sure what goes where!
Have i got all the bits i need, or do i need 2 sets of everything?

The fuse:


The holder:


And all of it:


Now, how do i know where to solder on the wires here?

As far as i can see, only one wire can go on each side, because it's all metal, so if i put 2 wires on it (for + and - ), then they will touch, making it a bit bad.

Can anyone, from looking at these pictures, tell me if i got the whole thing wrong, and should be draged out and shot, or if i can solder 2 wires on each side for + and - somehow (and possibly then get shot)

And what exactly are we trying to do here?

Put the fuse on the + wire & connect the - to the battery.

Just crimp the metal ends.

Oh i do appologize, in all my madnes i forgot to mention what im doing:
Im going to put this in between the battery and a car auxiliry socket so i can charge my phone / gps via the bike.

Instead of putting the socket straight to the battery, i was told by the very clever Sid Squid that i should put a fuse in between.
And that is what this i suppose to do.

Mind you, im not very technical

My guess:
1) poke wire through plastic
2) solder/crimp/attach wire to metal terminals
3) put metal terminals inside plastic, pull through wire
4) put in fuse
5) close plastic bit and attach wire to other electrical gubbins.

Oh, so the fuse doesn't connect to the negative at all?

Thanks for the quick replies!
As usual im useless without you lot!

No, it just breaks the Live wire.

As Viney says..the purpose of the fuse is to break the live circuit in the event of an excessive draw of current due to say a short in the system. Basically the neutral side of the electrics on a bike or car are taking any unused/unwanted elctricity to earth and so safety. the fuse would have no affcet being on the neutral line.

Dan's on the money as usual.

Local, we discussed this face to face not long ago, now tell we you were listening, yes?

Wrong, a fuse on the neutral would do exactly the same thing in the event of an excessive current draw as it would when on the live side, which is go 'pop' of course.

Just a note though that its better to have it on the live in a car/bike though as there is more chance of shorting a live against the frame (-) than the neg against a live terminal connection (+).
