[0057] At the same time, a sealing ring 5 is limited in the top port of the waterproof plug body, and the sealing ring 5 is limited by a limiting convex ring at the port of the waterproof plug body. The slots 63 and the convex pieces 64 are arranged alternately, and the convex pieces 52 are arranged in sequence at a certain angle adjacent to each other. The opening direction of the slot 63 forms an acute angle of 15-45° with the normal direction of the outer wall circumference of the plug body 6 at this location, such as Figure 3 As shown in the angle θ in the middle. Based on this design, when the end cap 6 is gradually screwed down and screwed with the external thread of the upper side wall of the waterproof plug body 5, the spherical concave surface on the upper inner wall of the end cap 6 gradually contacts the upper end of the protrusion 64, giving the protrusion 64 an inward and downward force, so that the protrusion 64 begins to deform from a vertical state. Since the direction of the slot 63 is at an angle to the normal, the protrusion 64 is not directly pressed toward the axis after deformation, but is biased toward another adjacent protrusion 64. By analogy, the gradually deformed protrusions squeeze each other and gather inward, so that the protrusions tightly wrap the sealing ring 5 and the wire passing through the through hole 62 at the top of the end cap, achieving a waterproof and dustproof sealing effect after wiring; at the same time, the sealing ring 5 completely wraps the outer skin of the wire, so that there is no gap for water to enter, so as to achieve a waterproof effect. The sealing ring adopts a silicone ring; so that the waterproof performance is better.

[0058] Furthermore, sealing rings 305 are provided between the waterproof connectors 6 at both ends of the installation through hole 302 and the two side surfaces of the middle plate 300, and between the waterproof connector 6 at the top of the middle plate 300 and the step surface 306 at the top of the middle plate 300. The sealing rings are rubber sealing rings. The structure makes the waterproof performance better.

[0059] Based on the above, after a waterproof member is added to the wire connection mechanism with a three-terminal interface, its insert sleeve 2041 is inserted into the top port of the longitudinal channel 303, and the positioning sleeve 13 is inserted into the bottom port of the longitudinal channel 303 to respectively position the first wire connector 100 and the second wire connector 200. At the same time, the upper side wall of the mounting through hole 302 has a guide groove 307 matching the positioning sleeve 13, so as to facilitate positioning the positioning sleeve at the bottom port of the longitudinal channel.

[0060] In summary, the first conductive spring of the first wire connector and the second conductive spring of the second wire connector are both made of U-shaped conductive copper sheets, while the conductive plate and the conductive plug plate are both made of conductive copper plates, and the wiring housing (composed of an intermediate block and a mounting block) and the waterproof housing (composed of an intermediate plate body, a waterproof connector and a waterproof end cap) are both insulating housings.

[0061] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, all technical solutions that are the same or similar to those of the present application fall within the protection scope of the present invention.
