1. A sensing transformer comprising:
- (a) a first transformer portion defining a first guide element and a first directing element;
(b) a second transformer portion defining a second guide element and a second directing element, said second guide element slidingly engageable with said first guide element, said second directing element slidingly engageable with said first directing element, the combination of said second guide element being said slidingly engageable with said first guide element and said second directing element slidingly engageable with said first directing element to contemporaneously direct translation and rotation of said second transformer portion relative to said first transformer portion;
(c) a first latch element including a first latch surface projecting from said first guide element; and
(d) a second latch element resiliently attached to said second transformer portion and including a second latch surface arranged to resiliently engage said first latch surface when a first core portion of said first transformer portion is urged into contact with a second core portion of said second transformer portion and to resist separation of said first core portion and said second core portion.

5. A sensing transformer comprising:
-
(a) an elongate first core portion; (b) a first core housing enclosing a portion of said first core portion and defining an elongate guide pin having a guide pin axis extending normal to a longitudinal axis of said first core portion and spaced from a side of said first core portion, said guide pin defining a first directing surface; (c) a second core portion having plural end portions arranged for engagement with said first core portion; and (d) a second core housing enclosing a portion of said second core portion and defining a guide pin receiving socket spaced from a side of said second core portion, and a second directing element slidingly engageable with said first directing surface, the combination of (1) said guide pin and said guide pin receiving socket and (2) said second directing element slidingly engageable with said first directing surface to control translation and rotation of said first core housing relative to said second core housing as said first core portion is urged toward contact with said second core portion. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14)
