[embodiment]

Fig. 1 to Fig. 2 is first embodiment of the utility model battery connector.

Battery connector 100 comprises that insulating base frame 1, positive terminal 3 and negative terminal 2, two conducting terminals are fixed in the insulating base frame 1.

Insulating base frame 1 comprises circular bottom wall 10 and sidewall 11, diapire 10 and sidewall 11 formation one can be accommodated the accepting groove 12 of battery, sidewall 11 non-sealings, which is provided with a breach 13, be provided with an elastic arm 14 in this breach 13, this elastic arm 14 is to extend upward from diapire 10 edges, elastic arm 14 inboards are provided with projection 141 in the appropriate location, the upper surface of projection 141 slopes inwardly, the guiding face 142 that formation can supply battery to pack into, elastic arm 14 is provided with a through hole 15 with diapire 10 junctions, and sidewall 11 is at the accepting hole 16 that runs through diapire 10 that is provided with respect to the opposite side of breach 13.

Negative terminal 2 comprises the conducting strip 21 that is positioned on the bottom surface and passes the pin 22 of insulating base frame 1 through hole 15.Conducting strip 21 is a laminated structure, it comprises base portion 211, bends the connecting portion 212 of extension downwards and extend leading section 213 from connecting portion 212 ends from base portion 211 1 ends, also offers a medium altitude groove 214 in the middle of this conducting strip 21, and conducting strip 21 is the arch bridge shape, so, conducting strip 21 has elasticity.Positive terminal 3 is a rectangular plate shape, it comprises the fastener portion 33 that base portion 31, the pin 32 that extends from base portion 31 reach from base portion 31 other ends are bent to form downwards, positive terminal 3 is fixed in the accepting hole 16, the lateral margin of base portion 31 can be provided with chamfering or hangnail to strengthen fixation, and wherein fastener portion 33 and the projection 141 on the elastic arm 14 form the buckle structure of the battery that can lock.

When battery is installed, at first, battery one end is placed the lower edge of positive terminal 3 fastener portions 33, press down the battery other end then, battery slips over the guiding face 142 of elastic arm 14, elastic arm 14 expands outwardly, battery enters accepting groove 12, makes the conducting strip 21 pressurized elastic deformations of negative terminal 2 and contact with the battery floor surface elastic, and projection 141 and positive terminal 3 clips are in the battery upper surface, so, battery is stablized fixing.When taking out battery, outwards pull elastic arm 14, make battery break away from projection 141 and fix, elastic conducting strip 21 pops up battery, so, can take out battery easily.Certainly, for preventing that elastic arm 14 from suffering extraneous damage, a leg 17 that outwards protrudes can be set at breach 13 places of insulating base frame 1, this leg 17 is connected in breach 13 side walls 11, height maintains an equal level substantially with elastic arm 14, and this leg 17 is wrapped in its inside with elastic arm 14.In this embodiment, also can directly at the sidewall apical margin with respect to breach 13 the fastener portion 33 that edge clipping replaces positive terminal 3 be set, so, the projection 141 of edge clipping and elastic arm 14 also can form the buckle structure of self-contained battery.
