Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a connector with a high-strength rotary locking structure. Background Technology

[0002] With the continuous expansion of application scenarios for new energy vehicles such as electric riding devices and electric motorcycles, the requirements for performance and handling stability of these vehicles are increasing. Inside the vehicle, connectors, as key components, must not only undertake high-power transmission tasks to ensure a stable power supply, but also possess high contact reliability to maintain stable signal transmission. Furthermore, considering the frequent operations during vehicle use, connectors must be adaptable to various high-frequency operating environments.

[0003] However, most power connectors currently on the market use a rotary locking structure made of plastic. Due to the limitations of plastic materials, this structure cannot meet the demands of high-frequency and high-intensity user operations. For example, under prolonged and frequent insertion and removal and rotation operations, the plastic rotary arm is prone to wear and breakage, leading to a shortened connector lifespan, affecting the normal use of new energy vehicles, increasing maintenance costs, and posing safety hazards. Therefore, designing a rotary locking connector with high transmission capacity, durable insertion and removal resistance, a built-in locking structure, and high strength is an urgent problem to be solved.

[0012] The preferred technical solution is as follows: the locking arm is configured as a U-shaped structure, including two side arms and a drive arm connecting the two side arms; the two opposite sides of the male connector plug end are provided with rotating shafts, the two side arms are provided with shaft holes, and the two shaft holes are fitted onto the two rotating shafts in a one-to-one correspondence.

[0013] The preferred technical solution is as follows: the drive arm is provided with a push lock, the male connector is provided with a buckle, and the push lock and the buckle are correspondingly matched.

[0014] A preferred technical solution is as follows: a sealing gasket is provided on the plug end of the female connector, and a sealing cover is connected to the sealing gasket through a connector. The sealing cover is matched with the plug end of the female connector.
