Problems solved by technology

like Figure 5 For the button battery device shown, when the button battery is installed with the protection board 7b, the positive and negative input interfaces of the protection board 7b need to be electrically connected with the positive and poles of the button battery respectively, and the lower case of the button battery has positive polarity , the top cover has a negative polarity, so its negative input interface 72b is drawn out from the top cover, while the positive input interface 71b is drawn out from the lower shell and goes around to the top of the top cover along the casing, so the space utilization rate is low

Embodiment Construction

[0021] figure 1 A button battery in some embodiments of the invention is shown, which may preferably be a button battery. As shown in the figure, the button battery includes a sealed casing 1 , an electrode isolation assembly 2 , an insulating sealing body 3 and a conductor 4 . In some embodiments, the casing 1 includes a conductive top cover 12 , the top cover 12 has a conductive top wall 121 , and an outlet hole 123 is opened on the top wall 121 . The insulating sealing body 3 is hermetically plugged in the lead-out hole 123 , and the conductor 4 is vertically penetrated in the insulating sealing body 3 , and its two ends are respectively exposed from the two ends of the insulating sealing body 3 . The insulating sealing body 3 insulates the conductor 4 from the top cover 12 . The electrode isolation assembly 2 is arranged in the casing 1, which includes at least one positive electrode 21, at least one negative electrode 22 and a separator 23 between the positive electrod...

Abstract

The invention relates to a button battery which comprises a shell and an electrode isolation assembly arranged in the shell, wherein the electrode isolation assembly comprises at least one anode and at least one cathode; the shell comprises a conductive end wall; the end wall is electrically connected with one of the at least one anode and the at least one cathode; the end wall comprises at leastone lead-out hole; a conductor is arranged in the at least one lead-out hole; an insulation sealing body insulated from the end wall is arranged between the hole wall of the at least one lead-out holeand the conductor; the conductor is electrically connected with the other one of the at least one anode and the at least one cathode. The invention further relates to a button battery device which comprises the button battery and a protective plate mounted on the end wall of the button battery; the protective plate comprises positive and negative input interfaces and positive and negative outputinterfaces; the positive and negative input interfaces are electrically connected with the anode and the cathode of the button battery respectively.

Description

technical field [0001] The present invention relates to a battery, and more particularly, to a button battery. Background technique [0002] Button cells of the known art generally comprise a casing consisting of two electrically conductive casing halves, a lower casing and a top cover respectively. Typically, the lower case has positive polarity and the top cap has negative polarity. Such as Figure 5 For the button battery device shown, when the button battery is installed with the protection board 7b, the positive and negative input interfaces of the protection board 7b need to be electrically connected with the positive and poles of the button battery respectively, and the lower case of the button battery has positive polarity , the top cover has a negative polarity, so its negative input interface 72b is drawn out from the top cover, while the positive input interface 71b is drawn out from the lower case and goes around to the top of the top cover along the casing, and...
