The product can be plugged into two cables to achieve data transmission, power supply, and connection suitable for device sensor action. It is simpler for users to connect wiring and is suitable for various applications in industry, construction, automated machinery, machinery, automobiles, aviation and other fields. The male end wire connection adopts a press-connection terminal and wire puncture connection, and the female end is a PCB board end connector. The male and female connectors are designed with a snap-on design. The design of the male terminal entrance adopts a needle-type wire end metal conductor, which is inserted and connected with the female end board end metal connecting piece. The cap body and the cap ring are screwed together with internal and external screws, which can make the wire connection more secure and the wire is not easy to fall off. The outer ring of the wire end nut sleeve is designed with ribs to increase locking and anti-slip when using the product. The rubber ring block inside the cap ring is designed with the same arc angle as the rear end of the cap body, which can clamp the wire more tightly during the screw connection process. The tail ends of the upper and lower shells are added with wire tie rings to implement a snap-on method. In order to prevent the spring piece of the protruding part of the upper shell from bouncing open, an anti-detachment mechanism is designed at the corner. BRIEF DESCRIPTION OF THE DRAWINGS
