[0001] This utility model relates to the field of connectors, specifically to a high-current charging connector with signal transmission. Background Technology
[0002] In the existing technology, the charging connectors used on short-distance vehicles such as electric bicycles, scooters, and electric motorcycles are generally designed for low-current charging and direct power supply after insertion. They lack signal control and sometimes start supplying power even when the male and female connectors are not fully inserted, which is not safe. In addition, they are not suitable for situations that require fast charging. Utility Model Content
[0003] To address the aforementioned shortcomings of existing technologies, the technical problem this invention aims to solve is how to improve the signal control and high-current performance of charging connectors. The specific technical solution is as follows:
[0004] A high-current charging connector with signal transmission includes a male connector and a female connector. The male connector includes a male connector base and a male connector transmission assembly. The male connector transmission assembly is installed inside the male connector base. The female connector includes a female connector base, a female connector transmission assembly, and a female connector sleeve. The female connector sleeve is installed behind the female connector base. The female connector transmission assembly is installed inside the female connector base and the female connector sleeve. The female connector transmission assembly includes a positive pin, a first negative contact spring, a second negative contact spring, and a signal contact spring. An outer column is provided behind the female connector base, and a central column is provided at the center of the outer column. The positive pin is inserted into the central column. The outer wall of the central column is separated from the inner wall of the outer column to form a cavity. The first negative contact spring, the second negative contact spring, and the signal contact spring are respectively installed on the outer column. The rear ends of the first negative contact spring and the second negative contact spring are shorted by solder wire. After the male connector is inserted into the female connector, the signal contact spring is electrically connected to the first negative contact spring and the second negative contact spring through the male connector transmission assembly.
[0005] As a preferred embodiment of this utility model, the male transmission component includes a conductive post, an inner insulating sleeve, an inner male pin, an outer insulating sleeve, and an outer conductive ring. The inner insulating sleeve is installed inside the conductive post, and the inner male pin is installed at the center of the inner insulating sleeve. The outer insulating sleeve is installed outside the conductive post, and the outer conductive ring is installed outside the outer insulating sleeve. After the conductive post is inserted into the cavity, the positive pin is inserted into the inner male pin, and the signal spring, the first negative spring, and the second negative spring all contact the outer conductive ring.
[0006] As a preferred embodiment of this utility model, the front end of the signal spring is bent and extends into the cavity, and the middle parts of the first negative electrode spring and the second negative electrode spring are bent and extend into the cavity.
[0007] As a preferred embodiment of this utility model, the male base is coated with rubber to fix the conductive post, the inner insulating sleeve, and the tail of the inner male pin.
[0008] As a preferred embodiment of this utility model, the male base is provided with a waterproof silicone ring on its outer periphery, and the outer diameter of the waterproof silicone ring is slightly larger than the inner diameter of the female base.
[0009] Beneficial effects: Compared with the prior art, the main improvement of this utility model lies in the improvement of the female connector transmission component. The rear ends of the first negative spring and the second negative spring are short-circuited by solder wire. The two negative springs meet the requirements of high current transmission. After the male connector is inserted into the female connector, the signal spring is electrically connected to the first negative spring and the second negative spring through the male connector transmission component. The signal spring can feed back the connection signal to the connector management system, and the connector will then start. Adding a signal spring is beneficial to controlling the connector start-up and increasing safety. Attached Figure Description
