In a preferred embodiment, the diameter at second end is from the junction with the first end to away from described The direction of first end is gradually reduced.

In a preferred embodiment, the shell fragment is arcuate structure.

In a preferred embodiment, the boss of annular is provided with the inner bottom wall, the shell fragment is arranged at described Boss is close to the side of the madial wall.

In a preferred embodiment, the battery main body is cylindric.

In a preferred embodiment, the madial wall is cylinder, the inner bottom wall for it is circular and with the inner side Wall vertical connection.

Battery connecting construction of the present utility model, the first end of the negative pole are provided with the first screw thread, and the of the negative pole Two ends are arranged to frustum, the second screw thread being engaged with first screw thread are set on the madial wall of the positive pole, connection is surely Gu；Second end is resisted against the shell fragment for being arranged at the inner bottom wall, and contact area is big, and contact resistance is small, and impedance is low, so as to connect Contacting surface caloric value is reduced.

【Brief description of the drawings】

Fig. 1 is the sectional view for the battery connecting construction that the utility model embodiment provides.

Fig. 2 is positive pole, the sectional view of negative pole and shell fragment shown in Fig. 1.

Fig. 3 is the top view of the positive pole and shell fragment shown in Fig. 1.

Fig. 4 is the sectional view that the positive pole shown in Fig. 1 is connected with negative pole.

【Embodiment】

In order that the purpose of this utility model, technical scheme and advantageous effects become apparent from understanding, below in conjunction with Accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely retouched State, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole embodiments. Based on the embodiment in the utility model, those of ordinary skill in the art are obtained under the premise of creative work is not made Every other embodiment, belong to the utility model protection scope.

Referring to Fig. 1, a kind of battery connecting construction 100 provided by the utility model, including battery main body 10, negative pole 20, Positive pole 30 and shell fragment 40.

The battery main body 10 is substantially cylindrical.

Please refer to Fig. 2, the negative pole 20 is arranged at one end of the battery main body 10.The negative pole 20 includes first End 21 and the second end 22 being connected with the one end of first end 21.The first screw thread 211 is provided with the first end 21.Second end 22 be frustum and diameter is gradually reduced from the junction with the first end 21 to the direction away from the first end 21.

Please refer to Fig. 3, the positive pole 30 is arranged at the other end of the battery main body 10.The positive pole 30 is hollow Structure and one end open.The positive pole 30 includes madial wall 31 and the inner bottom wall 32 positioned at the one end of madial wall 31.The madial wall 31 be cylinder, the inner bottom wall 32 for it is circular and with the vertical connection of madial wall 31.The madial wall 31 is away from described interior One end of bottom wall 32 is provided with the second screw thread 311 that can be engaged with first screw thread 211.Set in the inner bottom wall 32 There is the boss 321 of annular.
