To achieve the above object, the utility model provides following technical scheme：A kind of shell fragment group knot in parallel for battery core Structure, is made up of M row N row shell fragments, and M and N are not less than 2, and the shell fragment includes shell fragment base, and each shell fragment base is circumferentially uniform It is provided between four connection sheets, two adjacent connection sheets of each shell fragment base and is provided with two shell fragment pawls, connection sheet and bullet Piece Claw is arc-shaped, and shell fragment pawl is arranged on shell fragment base；（With a line or same row）Distance between two adjacent shell fragments Connected between two nearest connection sheets by Spring sheet clip, arc-like sheet of the Spring sheet clip by upper cover plate and positioned at both sides below upper cover plate Composition, two arc-like sheets of Spring sheet clip are located at two connection sheets respectively（Two closest companies between two adjacent shell fragments Contact pin）Inner side, upper cover plate is located at the top of two connection sheets；Connection sheet and shell fragment pawl are arc-shaped, and to shell fragment bottom Seat center curvature；Two arc-like sheets of both sides are respectively to two lateral bends of upper cover plate below upper cover plate.

It is preferred that, the shell fragment base is provided with back taper blind hole.

It is preferred that, the height of the Spring sheet clip is less than shell fragment pawl.

It is preferred that, the width of the connection sheet is more than the width of shell fragment pawl.

Technique effect of the present utility model and advantage：Battery core is directly parallel in together by connection sheet, save parallel-connection network The processing step of processing, technology is novel, is used manpower and material resources sparingly in production process, easy to connect firm, it is ensured that to shake Effective parallel connection of battery in journey.Technics comparing is simple, and the process-cycle is short, and processing cost is low.
