Description

Technical Field

[0001] The present invention relates to the technical field related to connectors, and in particular to a pogopin connector. Background Art

[0002] Pogopin connector, also known as spring pin connector, is a precision connector widely used in various electronic products to play the role of signal transmission connection. Its application areas are very wide, including but not limited to mobile phones, drones, smart robots, smart wearable series, battery chargers, Bluetooth headsets, automobiles, medical equipment and other electronic industries. The design features of this connector include small size and light weight, which can save space and beautify the appearance of the product. Therefore, its application in the automotive field is also one of its common application scenarios. Pogopin (spring pin) is mainly used for current and signal transmission, that is, charging and conductive functions.

[0003] Pogopin connectors include male and female ends. The male end usually refers to the part with a spring, i.e., the Pogopin spring pin, which is retractable and can adapt to different connection requirements. The female end is the flat surface part without elasticity, usually called a turning part or electrode. The combination of the male and female ends enables the Pogopin connector to achieve the transmission connection of current and signals.

[0004] At present, when the existing pogo pin connector is used in the automotive field, the spring pin in the male end is installed inside the housing, which is inconvenient to disassemble and thus cannot be quickly replaced with a new spring pin. Moreover, although the existing pogo pin connector is provided with a self-locking structure, the self-locking structure is mostly achieved by snapping an elastic cone head with a matching hole. Since the cone head is mostly made of plastic, it is prone to breakage, which reduces the life of the self-locking structure and causes the connection between the male end and the female end to lose fixation. This will cause the connection to become loose, thereby reducing the practicality of the pogo pin connector. Summary of the invention

The cone heads 308 are fixedly connected to the sides opposite to the outer tubes 307 with springs 309. The front and back sides of the left end of the lock shell 301 are fixedly connected to two side support plates 310. The ends of the two side support plates 310 that are away from each other are hinged with two force-bearing arc plates 311. The two force-bearing arc plates 311 are located on the opposite sides of the right ends thereof and are fixedly connected with two steel ropes 312. The two steel ropes 312 are fixedly connected to the two side support plates 310. The ends of the two arc plates 311 are respectively extended to the inside of the outer tube 307 and fixedly connected to the side away from the cone head 308. The left ends of the two force-bearing arc plates 311 are fixedly connected to two main drive plates 313. The upper surface of the left end of the main shell 101 is provided with an auxiliary groove 314. The front and rear inner walls of both ends of the auxiliary groove 314 are provided with two slide grooves 315.
