Low voltage recessed lighting burning wire connectors

Hello,
I have low voltage (12 Volts) recessed lighting in the kitchen, and when I change bulbs (Halogen 50 watts) I find that the wire connectors are burned, and I have to change connectors too (they "disintegrate" upon touching them). Should I be concerned about this, or is this normal? Bulbs usually last several years. I am somewhat concerned that this may be a risk for fire.

Thank you for your help! Glad I found this website

Are the sockets rated for 50W? Are there blocked ventilation holes?

This should not be happening. Could you post a pic of the burned contacts?

Hello,
Thank you for your responses. Yes, the socket is for 50 w. I am not sure about the ventilation holes.

Since I posted, I had changed the bulb, and then noticed a thin white smoke coming from the light fixture. I pulled it out and saw the connectors are completely melted! Something is really, really wrong. I have turned off for now and will call electrician tomorrow morning.

I have a pic of it, but don't know how to post pictures.

thanks again!

That looks like the wires are too close to the bulb. Halogen bulbs have a high surface temperature. That looks like a lot of excess wiring in the housing. Perhaps it has been pulled out of the junction box above the fixture.

so do you think if the bulb were farther away from connectors this would not have happened?

I am not sure I understand the following sentence:

"Perhaps it has been pulled out of the junction box above the fixture"

There is a junction box above the fixture where the house wires connect to the fixture. Between the fixture and the socket are some leads in a flexible conduit. The will slide in the conduit. You might be able to push some back towards the junction box.
