Magnetic type miner lamp with convex-shaped charging contact

Abstract

The invention discloses a magnetic type miner lamp with a convex-shaped charging contact. The magnetic type miner lamp with the convex-shaped charging contact mainly comprises a miner lamp head, a miner lamp cable, a battery and a charging plate, the battery is packaged by a plastic shell body and provided with an absorbing plate, magnetic iron is arranged on the charging plate, the convex-shaped charging contact is arranged on a battery plastic shell body, and a fixed charging contact is arranged on the charging plate. When the battery is close to the charging plate, an iron plate and the magnetic iron are absorbed together, the convex-shaped charging contact is contacted with the fixed charging contact, and the battery begins to charge. The magnetic type miner lamp with the convex shaped charging contact conducts positioning and charging by magnetic absorption and charging a convex point. The fixed charging contact of the charging plate is tightly contacted with the convex shaped charging contact of the battery, charging state is good, and the problem that charging and communication are not conducted due to poor contacting can be effectively solved.

Description

technical field [0001] The invention relates to a miner's lamp, in particular to a magnetic suction type miner's lamp with a convex charging contact. Background technique [0002] At present, the miner's lamp in the prior art is a cable miner's lamp with a twist-type charging method. When using the miner's lamp charging cabinet to charge the miner's lamp, it is very inconvenient to operate in the small space of the miner's lamp charging cabinet because a twist is required to complete the charging of the miner's lamp. It is both labor-intensive and easy to cause injury to the operator's hand or damage to the miner's lamp caused by improper force; in addition, although the existing magnetic suction type miner's lamp is easier to operate than the twist-type cabled miner's lamp, due to the correspondence between the battery and the charging board The charging contacts are divided into two planes, and there is often a problem of poor contact of the charging contacts, resulting in...

[0002] At present, the miner's lamp in the prior art is a cable miner's lamp with a twist-and-twist charging method. When using the miner's lamp charging cabinet to charge the miner's lamp, it is very inconvenient to operate in the small space of the miner's lamp charging cabinet because a twist is required to complete the charging of the miner's lamp. It is both labor-intensive and easy to cause injury to the operator's hand or damage to the miner's lamp caused by improper force; in addition, although the existing magnetic suction type miner's lamp is easier to operate than the cabled miner's lamp with the twist-type charging method, due to the correspondence between the battery and the charging board The charging contacts are divided into two planes, and there is often a problem of poor contact of the charging contacts, resulting in no power or no communication
