Elastic electrical contact device

Abstract

The invention discloses an elastic electrical contact device, which comprises a plug and a socket. The plug is provided with a plug protection ring table and at least two fixed contacts. The fixed contact is provided with a static contact point, a static insulation and magnetic strips; the static insulation wraps the other surfaces of the static contact point except the contact surface of the contact point; the contact surface of the static contact point protrudes out of the convex surface of the static insulation; the two magnetic strips are arranged on the convex surface of the static insulation; the fixed contact is arranged in the plug protection ring table to form the plug; the socket is provided with a socket protection ring table, a proximity switch and a moving contact; the movingcontact is provided with a moving contact point, an insulator, a permanent magnet strip and an elastic piece; the insulator is provided with a counter bore, and the moving contact point is arranged inthe counter bore; and the elastic piece is arranged between the bottom surface of the moving contact point and the bottom surface of the counter bore. Electrical conduction connection is achieved ina contact mode, effective contact of the contacts is stably kept through permanent magnetic force, automatic butt joint is conveniently achieved, and safety and reliability are achieved.

Description

technical field [0001] The invention relates to the technical field of drone battery applications, in particular to an elastic electrical contact device. Background technique [0002] Unmanned aircraft is referred to as "drone", and the application of drones can be divided into military and civilian. In terms of military use, UAVs are capable of patrolling, reconnaissance, tracking, anti-terrorism, targeted killing and target drones. In terms of civilian use, it is currently used in aerial photography, agricultural plant protection, pasture monitoring, micro-selfie, express delivery, disaster relief, wildlife observation, epidemic monitoring, epidemic publicity, epidemic disinfection, surveying and mapping, local area networking, news reports, power inspections, river courses Applications in inspections, urban security, fire protection, film and television shooting, romantic creation, etc. The increasing maturity of industrial UAV technology, the improvement of mounting te...

Problems solved by technology

[0003] However, the existing rechargeable UAVs have the following problems during the charging process: (1) The charging method is usually charged by plugging in, which may easily lead to the charging of the UAV during the long-term plugging and unplugging process. Two-way damage to the power supply end affects charging efficiency and device safety; (2) Under normal conditions, the power supply end is in a long-term power supply state or needs to be switched manually. The former is prone to safety problems, and the latter is more difficult to operate. It is cumbersome, and the switch lacks the function of automatic power supply
