Abstract

Provided is a vacuum cleaner. The vacuum cleaner includes a cleaner body including a suction motor for generating a suction force, a suction part communicating with the cleaner body to suction air and dusts, a battery disposed in the cleaner body or suction part to supply a power to the suction motor, and a cleaner connector disposed on the cleaner body or the suction part, a charger including a charger connector separably connected to the cleaner connector to charge the battery, and a disconnection member disposed on the cleaner body or the suction part to selectively connect or disconnect the cleaner connector to or from the battery.

First claim

What is claimed is:

1. A vacuum cleaner comprising:
a cleaner body comprising a suction motor for generating suction;
a suction part communicating with the cleaner body to receive air and dust particles;
a battery disposed in the cleaner body or the suction part to supply power to the suction motor; and
a cleaner connector disposed on the cleaner body or the suction part;
wherein the cleaner connector comprises a terminal insertion part comprising a plurality of main body terminals connected to corresponding a plurality of charger terminals of a charger terminal part of a vacuum cleaner charger when the charger terminal part is inserted in the cleaner connector,
wherein the cleaner connector protrudes from the cleaner body or the suction part,
wherein each of the plurality of main body terminals comprises a first portion inserted into the charger terminal and a second portion having a bent shape extending from the first portion and connected to the cleaner body or the suction part.

2. The vacuum cleaner according to claim 1 , wherein the charger terminal part comprises an accommodation part accommodating the plurality of charger terminals and a plurality of terminal through-holes through which the plurality of main body terminals to pass therethrough and connect to the charger terminals, respectively.

3. The vacuum cleaner according to claim 2 , wherein each of the plurality of charger terminals has a main body terminal insertion groove into which each of the main body terminals passing through the terminal through-holes is inserted.

4. The vacuum cleaner according to claim 1 , wherein the plurality of main body terminals are spaced apart from an inlet of the terminal insertion part.
