Abstract

Aspects of the current subject matter relate to methods and system for protecting a battery cell and/or a /pack of multiple battery cells serving as a power source of a vaporizer device from developing a short-circuit in a vaporizer device. In one aspect, a vaporizer device is provided. The vaporizer device may include a power source including a battery and a power source lead extending outward from a distal end of the battery. The vaporizer device may further include a printed circuit board (PCB) electrically coupled to the power source via the power source lead extending outward from the battery. The vaporizer device may further include an insulator at least partially surrounding the power source lead. The insulator may be mechanically coupled to at least one of the power source and the PCB.

Claims (14)

1 . A vaporizer device, the vaporizer device comprising:

a power source comprising a battery and a power source lead extending outward from the battery;

a printed circuit board (PCB) electrically coupled to the power source via the power source lead extending outward from the battery; and

an insulator at least partially surrounding the power source lead, the insulator being mechanically and directly coupled to a distal end of the PCB and a proximal end of the power source;

wherein the PCB is at least partially in physical contact with a portion of the battery; and

wherein the insulator couples to the PCB within a recess of the proximal end of the power source.

2 . The vaporizer device of claim 1 , wherein the insulator comprises a polymer material.

3 . The vaporizer device of claim 1 , wherein the PCB is positioned superior to the insulator.

4 . The vaporizer device of claim 1 , wherein the insulator comprises an additional insulator piece installed superior to the PCB.

5 . The vaporizer device of claim 1 , wherein the insulator comprises an aperture.

6 . The vaporizer device of claim 1 , wherein the insulator is coupled to the PCB via a laser weld.

7 . The vaporizer device of claim 6 , wherein the laser weld comprises a weld tab coupled to the power source lead.

8 . The vaporizer device of claim 7 , wherein the insulator comprises an aperture.

9 . The vaporizer device of claim 1 , wherein the insulator is configured to secure the PCB in a fixed position with respect to the power source.
