A battery connector includes a number of connector blocks (1) each including an insulative housing (10) and a terminal (3) retained therein. The insulative housing has a mating face (11), opposite sidewalls (14) and a pair of slabs (16). Each sidewall and a corresponding slab define a passageway (17) therebetween. A pair of apertures (18) is defined through the sidewalls communicating with the passageways. The terminal includes a fixing portion (31) and a contact portion (30). The fixing portion includes a base section (32) and a pair of limbs (33) extending from the base section engaging with the passageways. Each limb forms a protrusion (331) thereon engaging with the aperture. The contact portion protrudes beyond the mating face to engage a terminal (50) of a rechargeable battery (5).
