Abstract
A battery (100) includes a terminal fixing portion (40) projecting outwardly from a lid body (14), and an outer cover member (60) covering the terminal fixing portion (40). The terminal fixing portion (40) includes a hole (42) into which an electrode terminal (30) is inserted. The outer cover member (60) includes a cylindrical portion (62) (deformation restricting portion) covering an outer peripheral surface (40b) of the terminal fixing portion (40) and restrict deformation of the outer peripheral surface (40b) of the terminal fixing portion (40), and a pressure application portion (64) that compresses against a top end portion (40a) of the terminal fixing portion (40) and causes the terminal fixing portion (40) to deform.
Claims18
A battery in which an electrode terminal is fixed to a battery case in an inserted state, comprising:
- a terminal fixing portion that projects outwardly from said battery case and includes a hole into which said electrode terminal is inserted;
- and
- an outer cover member completely external to the battery case, the outer cover member being in contact with and covering an outer peripheral surface facing in a radial direction and a top end surface facing in a projecting direction of said terminal fixing portion,
- wherein said outer cover member includes:
- a deformation restricting portion that covers the outer peripheral surface and the top end surface of said terminal fixing portion;
- and
- a pressure application portion projecting from the inner surface of the outer cover member and compressed into the top end portion of the terminal fixing portion,
- wherein the terminal fixing portion is deformed by the pressure application portion, and
- wherein the electrode terminal inserted into the hole is fixed to the terminal fixing portion of which an inside surface is protruded toward the inner diameter side.
A battery comprising:
- a battery case configured to received an electrode body;
- an electrode terminal configured to be inserted into the case;
- a terminal fixing portion projecting outwardly from the case and including a hole configured to receive the electrode terminal;
- and
- an outer cover member completely external to the case, the outer cover member being in contact with and covering an outer peripheral surface facing in a radial direction and a top end surface facing in a projecting direction of the terminal fixing portion, wherein the outer cover member includes:
- a deformation restricting portion covering the outer peripheral surface of the terminal fixing portion and configured to restrict deformation of the outer peripheral surface;
- and
- a pressure application portion configured to deform the terminal fixing portion by compressing against the top end surface of the terminal fixing portion;
- and
- wherein the top end surface faces away from an interior of the battery case.
A battery in which an electrode terminal is fixed to a battery case in an inserted state, comprising:
- a terminal fixing portion that projects outwardly from the battery case and includes a hole into which the electrode terminal is inserted;
- and
- an outer cover member completely external to the battery case;
- wherein the outer cover member is harder than the terminal fixing portion,
- wherein the outer cover member includes:
- a ceiling portion in contact with, covering, and compressing a top end surface facing in a projecting direction of the terminal fixing portion;
- and
- a cylindrical portion covering and compressing an outer peripheral surface facing in a radial direction of the terminal fixing portion,
- wherein the outer cover member and the terminal fixing portion together define an engaging portion,
- wherein an inside edge portion of the terminal fixing portion is plastically deformed into a recessed shape, and
- wherein the electrode terminal inserted into the hole is fixed to the terminal fixing portion of which an inside surface is protruded toward an inner diameter side.
