Connecting device and multi-rotor aircraft

Abstract

The invention discloses a connecting device and a multi-rotor aircraft. The connecting device comprises a first insertion piece and a second insertion piece. An insertion part is formed at the front end of the first insertion piece. First terminal mounting parts and at least one key mounting position are formed on the outer surface of the insertion part. First terminals are fixed in the first terminal mounting parts. A key is arranged in each key mounting position through a spring. An insertion cavity is formed in the second insertion piece. Second terminal mounting parts matched with the first terminal mounting parts are formed on the inner surface of the insertion cavity. Key ports matched with the keys are formed in the cavity wall of the insertion cavity. Second terminals are fixed in the second terminal mounting parts. The insertion part is inserted in the insertion cavity. The first terminal mounting parts are assembled to the second terminal mounting parts. The first terminals are electrically connected with the second terminals. The keys are arranged into the corresponding key ports under the action of the springs. The connecting device and the multi-rotor aircraft have the beneficial technical effects that the terminal butt-joint accuracy is high, and the connecting effect is good.

Description

technical field [0001] The invention relates to a connection device and a multi-rotor aircraft using the connection device. Background technique [0002] The existing multi-rotor aircraft mainly includes a fuselage, a plurality of arms integrally formed with the fuselage, and a plurality of propellers separately arranged at the ends of the arms. Since the arms are integrally formed with the arms, although this structure is simple, However, when electrically connecting the motor located at the end of the arm and the electronic speed controller located inside the fuselage, the connecting wire of the motor needs to pass through the ESC connected to the fuselage from the inside of the arm, and must be checked one by one Connecting the power cables and then plugging them into the machine arm is extremely cumbersome, inefficient, and increases the chance of errors. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a con...
