Embodiment approach

[0028] According to one embodiment of the present invention, the fastener can be completely accommodated in the connector 3, that is, it does not protrude outside the housing of the connector 3, so the fastener plays the role of passing through the protective circuit The through hole 10 of the board (the insulating part) is inserted into the battery cell 1 (for example, inserted into the hole 24 of the battery cell 1), the fastener can not only play the role of electrical connection, but also can play a role in stably protecting the circuit board 4 role. In this embodiment, the connector 3 can be fixed on the battery cell 1 in various ways, for example, by bonding, or fixing the connector 3 to the battery cell 1 by fastening screws.

[0029] According to another embodiment of the present invention, the fastener is not completely located in the connector 3 , but is fastened to the battery cell 1 through the connector 3 and the protective circuit board 4 from the outside in sequ...

Abstract

The invention discloses a battery, comprising a battery cell (1) and a connection structure (2) connected with the battery cell (1), wherein the battery cell (1) is provided with a first electrode and a second electrode; the connection structure (2) comprises a connector (3) and a protective circuit board (4) fixedly connected with the connector (3); the protective circuit board (4) is provided with a first electrode end (9) and a second electrode end which are respectively connected with the first electrode and the second electrode electrically; the protective circuit board (4) is also provided with a through hole (10) and a conductor enclosing the through hole (10); the conductor part is electrically connected with the first electrode end (9) and the first electrode of the battery cell (1) by a fastener; and the fastener passes through the through hole (10). The battery provided by the invention can ensure connection between the battery cell and the connection structure to be simpler, more convenient and more reliable.

Description

technical field [0001] The present invention relates to the battery field, and more specifically, relates to a battery, such as a lithium ion secondary battery. Background technique [0002] In recent years, with the rapid development of electronic terminal products, such as mobile phones, notebook computers, electric tools, etc., new requirements have been put forward for batteries as power sources in various aspects. For example, the battery structure is required to be more compact and the assembly is simpler. , more reliable performance and larger capacity. [0003] Such as figure 1 As shown, the battery includes a cell 1 and a connection structure 2 connected to the cell 1 , and the connection structure 2 includes a connector 3 and a protective circuit board 4 disposed in the connector 3 . However, a defect that often occurs in existing batteries is that the electrical connection is unreliable, which causes the battery to fail to work normally and be scrapped. Therefo...
