Claim of US Patent No. 9,748,719

1. A battery connector, for being mounted on a circuit board to electrically connect a button battery, the circuit board being
provided with a first conductive portion, a second conductive portion and a third conductive portion, and an indicating member
being electrically connected between the first conductive portion and the third conductive portion, the battery connector
comprising:
an insulating housing comprising a bottom wall, a plurality of elastic side walls which respectively connect with the bottom
wall and a plurality of protruding blocks, each protruding block protruding from the corresponding elastic side wall at a
position adjacent to the top of the corresponding elastic side wall, being spaced apart from the bottom wall and facing the
bottom wall, the bottom wall, the plurality of elastic side walls and the plurality of protruding blocks cooperating with
each other to define a limiting space for receiving and fixing the button battery;

a positive terminal fixed to the insulating housing, the positive terminal comprising a positive contact portion which extends
into the limiting space so as to contact a positive electrode on a side surface of the button battery and a first tail portion
which extends out of the insulating housing so as to maintain an electrical connection with the first conductive portion of
the circuit board; and

a negative terminal fixed to the insulating housing, the negative terminal comprising a negative contact portion which extends
into the limiting space so as to contact a negative electrode on a bottom surface of the button battery, a second tail portion
which extends out of the insulating housing so as to maintain an electrical connection with the second conductive portion
of the circuit board and a connection portion which is brought to move by the negative contact portion so as to electrically
connect with the third conductive portion when the button battery is received in the limiting space, the indicating member
being electrified to generate an indication signal by that the connection portion electrically connects with the third conductive
portion.
