Abstract
A battery holder (1) for receiving a coin cell (6) includes an insulative housing (2) and a first and a second contacts (4, 5) received in the insulative housing. The coin cell includes a positive pole (61) and a negative pole (62) with a smaller diameter than the positive pole thereby forming an annular receiving room (63) around the positive pole. The insulative housing includes a base plate (21), a bulge (22) and a number of chimbs (24) extending upwardly from the base plate and a protrusion (34) at a junction between the base plate and the bulge. The protrusion is mating with the receiving room around the positive pole for preventing the coin cell from reverse insertion.
