Double-spring electric conduction structure for battery and circuit board, and flashlight

Abstract

The invention discloses a double-spring electric conduction structure for a battery and a circuit board. The double-spring electric conduction structure comprises a lamp body cylinder, a tail cover device, the circuit board, the battery, a first spring and a second spring, wherein the battery is arranged in the lamp body cylinder, and the tail cover device is connected with the lamp body cylinder through threads; the circuit board is arranged on the end face of the inner side of the tail cover device and is opposite to the end face of the battery; the first spring and the second spring are tower-shaped and are located between the battery and the circuit board; the tower bottom end of the first spring and the tower head end of the second spring are located on a same side, and the tower head end of the first spring and the tower bottom end of the second spring are located on a same side; and the two ends of the first spring and the two ends of the second spring are respectively in contact with the circuit board and the positive pole and the negative pole of the battery. The invention further discloses a flashlight which comprises the electric conduction structure. According to the electric conduction structure, the electric conduction structure and performance between the battery and the circuit board are guaranteed to be more reliable, the light emitting property of the flashlight is stable, and the flashlight is simple to operate and use.

Description

technical field [0001] The invention relates to a conductive structure and a torch using the conductive structure, in particular to a double-spring conductive structure used for batteries and circuit boards in lamps and torches and a torch with the structure. Background technique [0002] Existing flashlights or similar lamps use various contact methods to achieve conductive functions; the conductive structure between the battery and the circuit board at the tail cover of the traditional flashlight is generally provided with elastic components on the circuit board Or two ordinary springs, which are connected to the battery through elastic parts or ordinary springs, to achieve electrical conduction; however, this conductive structure has relatively high requirements for the size and surface accuracy of the mating surfaces between the parts, which increases the manufacturing cost, and The structure is not reliable enough, and the performance is not stable enough. If two common...
