Say I have this LaTeX code:
\begin{equation}
\label{eq1}
V_{conf}(r) = \frac{A}{r^2} + Br^2  2\sqrt{AB}
\end{equation}
How to import it in MS Word?

See here for a list of several solutions, of whom some are free: 


There's an opensource converter here on SourceForge. I've not used it myself, but the comments look encouraging. 


I have been using Aurora (http://elevatorlady.ca/) to good effect in Word and PowerPoint. It integrates itself into the menu and calls your LaTeX environment (e.g. MikTeX) or its own minimal MikTeX. The rendered equations can be either bitmaps or vector. For sharing with others, the bitmaps are more portable. 


I'm guessing that you're using Windows, but on the offchance that you are using OS X, my preferred solution is LaTeXiT, which creates a picture of the equation that you can drag into Word or elsewhere. A potential Windows analog that I have not tested is Laeqed. 


I do this by using MathType with version >= 6.0.
