Description

Technical Field

[0001] The utility model relates to the field of connectors, in particular to a waterproof connector for a power supply controller of an unmanned aerial vehicle. Background Art

[0002] Connectors are also called connectors. They are also called joints and sockets in China. They generally refer to electrical connectors. They are devices that connect two active devices to transmit current or signals.

[0003] In commercial drones (such as agricultural drones, express delivery drones, etc.), their charging connectors generally use a high-current charging connection structure to ensure their endurance and work efficiency. However, in order to ensure the passability of large currents, existing connectors generally use larger diameter terminals and larger plastic shells to ensure that they can charge with large currents without arc interference.

[0004] For example, Chinese patent CN202111659930.4 adopts a structure of multiple spring clips to ensure that large current passes through while ensuring that the arc does not interfere. However, its structure is relatively complex, and the thickness of the spring clip is relatively small. Correspondingly, its resistance is also relatively large during use, which is prone to heat problems and affects the stability of the connector. Utility Model Content

[0005] The main purpose of the utility model is to propose a waterproof connector for a UAV power supply controller, which aims to improve the structure of the connector so that it can ensure its waterproofness, large current passability and arc non-interference, effectively ensure the rapid charging of the UAV, and the structure is relatively stable when installed on the UAV.

[0006] To achieve the above purpose, the utility model provides a waterproof connector for a drone power supply controller, comprising:

[0007] A female connector, the female connector comprising a female rubber shell provided with a first slot and a male terminal provided in the first slot, the female rubber shell being provided with an insertion slot, a partition being provided in the middle of the insertion slot, and the partition being provided between the two male terminals;

[0008] A male connector, the male connector comprising a male plastic shell provided with a second slot and a female terminal provided in the second slot, the female terminal being provided with a female slot for the male terminal to extend into, the male plastic shell being able to extend into the insertion slot, the male plastic shell being provided with a partition slot cooperating with a partition plate, the partition plate being able to extend into the partition slot;

[0009] The front end of the male terminal is a cylindrical structure;

[0010] The locking device is arranged between the female rubber shell and the male rubber shell, so that the male rubber shell and the female rubber shell are locked when they are plugged into each other.

[0011] In actual charging, the current passing through the connector is about 80A, so the contact area and spacing between the male and female terminals are related to the stability of the current. Through the cooperation of the grooves and partitions, the current breakdown problem between the terminals can be avoided, and the stability of charging is effectively guaranteed; in the actual design, its height is about 30mm, and a larger current can pass through a smaller space. At the same time, the stability of plugging and unplugging can be guaranteed, and the setting of the partitions and grooves also plays a guiding and limiting role. BRIEF DESCRIPTION OF THE DRAWINGS
