Patent ID: 7806739

Claim:
A battery connector comprising: an insulative housing defining a mating face; and a power contact, a signal contact and a grounding contact received in the insulative housing, each contact forming a contacting portion extending out of the mating face of the insulative housing; wherein a distance from the contacting portion of the power contact to the mating face is larger than a distance from the contacting portion of the signal contact to the mating face, wherein the signal contact is located between the power contact and the grounding contact, wherein a distance from the contacting portion of the grounding contact to the mating face is same as the distance from the contacting portion of the power contact to the mating face, wherein the insulative housing defines an assembling face perpendicular to the mating face, wherein the insulative housing comprises a pair of lateral walls and a pair of dividing walls parallel with the lateral walls, and wherein the lateral walls and the dividing walls define three passageways, further comprising a pair of reinforcing elements, and wherein each dividing wall defines a slit and each reinforcing element is received in a corresponding slit, wherein the insulative housing has a plurality of protrusions extending into the passageways and the contacting portions of the power contact, the signal contact, and the grounding contact each form a pair of wing portions opposing the protrusions, wherein each of the power contact, the signal contact, and the grounding contact has a soldering pad extending out of the insulative housing, a retaining pad retained in the insulative housing, an S-shaped curved portion connecting with the retaining pad and the contacting portion, and a locked portion connecting to the contacting portion, wherein the S-shaped curved portion comprises a first curved portion bending towards the assembling face at the upper face and a second curved portion bending towards the mating face at the assembling face.
